Description
~64~i!38 1. Background of the Invention The inven-tion disclosed herein was conceive~ in connection with an eEfort to manufacture small electric motors more e~Eiciently and economically. However, the principles may be used in the assembly of transformers, inductors and other devices such as relays which require the windin~ of wire on a form. For many years, machines have been used for winding wire on various forms. After the winding has been completed, the machine severs the wound coil from the supply reel, and as 10. a result the last turn, or few turns, may tend to loosen.
Accordingly, the next stage of production usually requires a manual operation wherein a worker must manually tighten the loosened turn, or turns, and apply some form of tape or harness to retain the individual turns in the desired position. In addition, it is common practice to manually strip the end of the wound wire of its enamel insulation and connect a heavier duty flexible wire to facilitate making external connections.
The connection is manually insulated and placed in a position to provide mechanical and electrical protection. These costly 20. manual steps tend to slow down the assembly process and fre-quently require a substantial number of skilled dexterous workers.
Various techniques have been developed to try to eliminate, or at least minimize manual operations. For example, U.S. patent 3,725,707 issued April 3/ 1973, to Leimbach et al and entitled Field Sub-assembly for Universal Electric Motors discloses a special terminal board and terminal which eliminates much of the hand labor of the prior art. However, the Leimbach et al patent requires a more complicated coil winding machine in that the starting end and terminating end of the coil must be laid in a 30. channeI of a -terminal and the channel crimped prior to the time that the wound coil is severed from the supply reel.
The teachings of the present invention overcomes the .. ~ - ~ , .
.
, 1. disadvantages of the prior art and does not require a more complex coil winding machine.
Summary of the Inven~ion The present invention employs a terminal receiving member as a part of the sub-assembly on which the coil is wound.
The terminal receiving member includes a well into which a ter-minal may be inserted subsequent to the winding and at a differ-ent assembly station. In a preferred embodiment, opposite faces of the well include funnel shaped slots into which the starting 10- and terminating ends of the coil are laid by the coil winding machine. The slot dimensions are chosen to constitute a press fit for the wire. Thereafter, the wound coil may be severed from the supply reeI without any danger of any portion of the wound coil coming loose. The sub-assembly, including the wound coil, may subsequently be transferred from the coil winding machine to a terminal inserting machine. The terminal inserting machine inserts a terminal into the well to make eIectrical con-tact with the coil ends laid in the slot of the well. As a simultaneous operation, an~ excess wire projecting beyond the 20- boundary of the well may be severed and discarded. The terminal is designed to accommodate another connection constituting a wire for external connections and which is inserted into the terminal and clamped thereby.
The assembly, including the terminal recei~ing well, may ; overlay the form on which the coil is to be wound in such manner ; that the winding of the coil helps to retain the terminal re-~` ceiving member in a predetermined position. In addition, the terminal receiving member may include a portion~ or portions, that will assist in retaining the wound coil within predetermined space limits. One form of the terminal receiving member includes a boss for securing the terminal receîving member to the form on which the coil is wound before the coil is wound. After the coil :. .
1. is wound, the boss may be knocked of~ if it is expedient to do so. The well into which the terminal is inserted includes a projecting member, or anvil, which helps to provide support for the wire as the terminal is inserted~
It is an objec-t of the invention to provide a new and improved means for terminating the ends, and center taps if used, of coils.
I-t is a more specific object of the invention to pro-vide a means for capturing and retaining ends and/or taps from 10. a wound coil so that the ends and/or taps will be securel~ re-tained in a predetermined position subsequent to the windin~
of the coil and the removal of the sub-assembly from that pro-duction stageO
It is another object of the invention to provide a terminal board which may be secured by a first holding means to the form on which the coil is to be wound.
It is another object of the invention to provide a terminal board which is retained on the form by the wound coil after it is wound.
20. It is another object of the invention to provide a structure wherein the first holding means may be broken off to facilitate a subse~uent assembly step.
It is another object of the inven-tion to retain the ends and/or taps of the wound coil in a predetermined location to ~acilitate the insertion of terminals in the terminal board for ma~ing contact with the coil ends.
It is another object of the invention to provide a terminal which makes contact with the coil ends and/or taps and into which another wire may be inserted for making external 30- connections.
It i5 another object of the invention to prov:ide a terminal which may be adapted to receive connections from -1~6~
1. another sub-assembly.
Brief Description of _he Drawing For a better and more complete understanding of the present invention together with other objects and advantages, the following description should be considered together with the drawing in which;

FigO 2 is a front view of the sub-assembly shown in 10. Fig. 1 with a partial cut-away section;
Fig. 3 is a fragmentary perspective view of a portion of the terminal board of the invention, showing a coil end and a terminal in position to be inserted into the terminal board;
Fig. 4 is a cross-sectional view of a portion of the terminal board together with an inserted terminall the end of the coil winding and an inserted wire for making external connections; and ~' Fig. 5 shows the portion of the terminal board which may be broken away to facilitate mounting of the sub-assembly.
20. Description o~ the Preferred Embodiment -~ he invention disclosed herein relates to a terminal board and the manner in which it may cooperate with a sub-assernbly on which a coil is to be wound such that the terminal board is retained on the sub-assembly by a first means before the coil is wound and wherein the terminal board is retained by a second means after the coil is wound. The terminal board includes means for capturing and re-taining the ends, and/or taps, of wound coils. The invention also discloses a termlnal means for providing electrical continuity be~ween the coil 30- ends and external leads. While the invention disclosed herein may find utility in a wide variety of applications including transformers~ relays and inductances, it is disclosed more 1. specifically with respect to a small universal motor.
Considering now more speciEically Figs. 1 and 2, there will be seen therein a sub-assembly illustrated generally as 101 comprising a lamination stack 102 held together by a pair of rivets 103. The lamination stack 102 also has holes 105 which may extend through the entire lamination stack 102 or which may penetrate only a portion of the lamination stack 102 depending upon the s~ecific means which may be used for mounting the sub-assembly in a housing (not shown). The lami-10. nation stack 102, as viewed in Fig. 1, is generally circular incross section and includes a pair of pole pieces 106 and 107 through which magnetic ~lux is directed across an armature (not shown) which is subsequently placed in the cavity 108. In order to generate the magentic flux, coils will be wound in the pairs of winding slots 109 and 110. Machines for efficiently and expeditiously winding coils in the winding slots 109 and 110 are well known.
Moun-ted on the lamination stack 102 is a terminal board illustrated generally as 115 and comprising a plurality 20. of terminal wells 116 which are shown in some addi~ional detail in Figs. 3 and 4. The terminal board 115 has arms 117 which ; extend from the terminal well area and follow the general out-line of the lamination stack including the winding slots 109 and 110. The arms 117 terminate in ribs 118 which join wings ` 119.
Prior to the winding.of.the coils in the winding slots 109 and 110, it is conventional to place insulating slo-t : liner in the slots 109 and 110~ In order to avoid confusion in the drawing, such slot liners have been omitted since their use 30- is conventional and well known. When the coil 120 5not shown ; in Figs n 1 and 2/ but shown in Figs. 3 and 5~ is wound in the ~: winding slots lOg and 110, the individual turns thereof make : _5_ .~
.. - . -; . . ~ . . . .
. i. . . - : : ~: . : . :
1. physical contact wi-th the ribs 118 and help to :re-tain the ter-minal board 11~ on the lamination s-tack 102. The wings 119 serve to retain the coil 120 away from the armature cavity 108.
The terminal board 115 includes a pair of bosses 121 which extend into the mating hoLes 105 as a press fit and retain the terminal board 115 on the lamination stack 102 prior to the winding of the coil 120 in the winding slots 102 and 110. As will be seen later, the bosses 121 may be knocked off after the terminal board 11~ is retained in its position by the coil 10. 120. The bosses may have holes lO~o As may be seen more clearly in Fig. 3, each termlnal well 116 is generally rectangular in cross section and has "Y"
shaped slots 126 in opposite walls 127 and 128 of the terminal wells 116. The base 1~9 of the Y slo-t 126 is proportionecl so that it will snuggly grasp and re-tain an end 130 of coil 120.
That is., the base 129 of the slot 126 has a width which is approximately equal to the diameter of the wire 130 which is an end, or center tap, of the wire of the coil 120.
When the coil winding machine (not shown) starts 20. winding a coil, the starting end 130 of the coil is laid into one of the Y slots 126 of one of the terminal wells 116 and urged towards the base 129. If the coil 120 has a center tap, a loop of wire will be brought out and urged towards the base 129 of another slot 126 of another well 116. When the coil 120 is fully woundrthe termi.nal end thereof, which will be simi-lar to wire 130 t will be laid into another slot 126 and urged to the base 129 thereof in yet another terminal well 116. Sub-se~uent to this placement of the coil end, the end 130 will be severed from the supply spool. The snug fit between the coil 30- end 130 and the base 129 of the slot 126 will retain the coil end 13Q in position and prevent the loosening of the last few turns of the coil 120. This re.tention of the coil end and ' - : . . . ~ . . . .
lo maintenance oE the inkegrity of the winding 120 e:Liminates the need Eor a subsequent manual opera-tion to snug up the last Ee~
turns of the winding 120 ancl the use oE auxlliary means for re-tainin~ the Eorm of the winding 120.
Considering now more specifically Figa ~ which con-stltutes a cross section oE the terminal well 116 taken throu~h the center oE the Y slots 126, it will be observed that at the base of the well 11~ there is an anvil 132 which is generally circular, or oval, (as seen in Fig. 1) and whose top sur~ace is 10. slightly below the base 12~ of the slots 116n It will al.so be observed from FigO 4 that the base 129 of the Y slot 126 in outer wall 128 is stepped with the lower level Eacing the in-terior o~ the well 116. The function of this step will be de-scribed more fully hereinaEter in connection with the descrip-tion of the insertion of the terminal 135 into the terminal well 116.
Upon completion of the sub-assembly 1019 including wind-ing the coil 120 and laying the coil ends and taps into slots 126, the assembly may leave the winding station and proceed 20- to the terminal installation station. As the sub-assembly 101 is conveyed from the winding station to the terminal in-stallation station, there is no tendency Eor the ends of the coils 120 to loosen inasmuch as they are securely retained with-in the ~ase 129 of the Y slots 126. The coil ends 130 protrude beyond the ou~er wall 128 of the terminal wells 116 and the wire 130 has enamel insulation thereonO The sub-assembly 101 is automatically oriented and posi-tioned at the terminal inserting station so that terminals 135 may be automatically inserted into any or all oE the terminal wells 116 wherein i-t is desired to have a terminal 135~ Generally spea]~ing~ -the outer dimensions of the terminal 135 are such as to constitute a secure :Ei-t into the terminal well 116n In addition, the terminals 135 may be ~ ~6~
1. equipped with serrations 136 which coact wi-th the interior surfaces of the well 116 to securely retain the terminal 135 within the confines oE the well 116 subsequent to the insertion of the terminal 135 into the well 116. That is, the serrations 136 are oriented to permit insertion of the terminal and resist removal thereof. That is, the serrations 136 di~ into and em-bed themselves in the plastic material of which the terminal board 115 is Eabricated. The terminal 135 will be seen to ha~e a generally "U" shape, but with a member 140 extendin~ downward 10. from an upper arm of the U towards the interior base of the other arm of the U. Thus, the terminal 135 is seen to comprise a single piece of metal shaped to form a first wall 137, a base 138, a second wall 139 and an interior member 1~0. The terminal 135 has a cut-away portion 141 which is relativaly wide in the base member 138 and narrows into slots 142 and 143 in the walls 137 and 139~ respecti~ely. The slots 142 and 143 are sized and shaped so that as the terminal 135 is pressed into the terminal well 116 these slots will engage the wire 130, pierce the enamel insulation on the wire 130 and make a good electrical contac-~
20. between the wire 130 and the terminal 135. The cut-away portion 1~1 in the base 138 allows the terminal 135 to s~raddle the anvil 132 as the terminal 135 is pressed into the terminal well 116.
As the slots 142 and 143 Eirst engage the wire 1~0, the portion of the wire 130 within the well 116 will be pressed down into contact with the upper surface of the anvil 132 and the base 12g of the slots 126. Further movement of the terminal 135 into the well 116 will cause the piercing of the enamel insulation already mentioned. In additionl prior to the full insertion of the ter-minal 135 into the well 116, the portion of the wire 130 which 30. e~tends outside the outer wall 128 will be sheered ofE by a means not shown. The final seatin~ of the terminal 135 within the well 116 will tend to draw the end oE the wire 130 towards the interior 1- oE the well 116. That is, the end of the w.ire 130 will not protxude beyond the outer sur~ace 128 oE the terminal board 115. This provides protection against accidental contact of the coil end 130 with a metal housin~ within which the sub-assembly 101 may be placed. The stepped shape at the base 129 of the ~ slot in the wall 128 assists in pullin~ in the end of the wire 130. When the terminal 135 ls fully inserted in the well 116, a portion of the wire 130 rests on the anvil 132. The wire 130 is also securely gripped within the slots 10- 142 and 143 of the terminal 135 to make good electrical contact therewith. If desired, the an~il 132 could include a slo-t having a width approximately equal to the wire diameter.
In order to make electrical connections from an ex-ternal power source to the coil 120, a wire 145 is inserted into -the terminal 135 as shown in Fig. 4. The stripped and tined end 146 of the wire 145 is securely retained within the terminal 135 by the sprin~ action of the interior member 140~
That is, the end 147 of the interior member 140 is positioned so close to the wall 137 that insertion of the wire end 146 20- therebetween will urge the end 147 of member 140 away from wall 137 and the spring tension Qf the interior member 140 will retain the wire end 146 in position. The shape and angle, of contact of the interior member 140 and the wire end 146 are such as to make it difficult to remove the wire 145 once its end 14~ has been inserted into the terminal 135. The anvil supports the wire 130 and prevents the insertion of the wire 146 from disturbin~ the wire 130. That is, the anvil 132 and the wire 13~ on it provide a down stop for the wixe end 146~
As previously mentioned, the terminal board 115 is first held on the lamination s-tack 102 by means of -the bosses 121 which press fit into the holes 105 (see Fi~s. 2 and 5~.
Subsequently, the windin~ of -the coil 120 over the ribs 11 _g_ - .
1. provides an alternate means for holdiny the terminal board in its position on the lamination stack 102. Accordingly, after the winding of the coils 120, the bosses 121 can be knocked off the terminal board 115. Therefore, if it is convenient or ex-pedient to do so to mount the assembly 101 to a frame or within a housing (not shown), a bolt 150 may be in<,erted into the holes 10~ of the -terminal board and forced therein to knock off the boss 121 of the terminal board 115 and push it through the holes 105 of ~he lamination stack 102 and discard it~ The bolt 150 10. can then be used to attach the sub-assembly 101 to a housing.
Because the terminal board 115 is first held on the lamination stack 102 by means o~ the bosses 121 interacting with the holes 105 and that the terminal board is later held by the coi.l 120 acting with the ribs 118, there is no need ~or any por-tion of the terminal board 115 to extend beyond the boundaries of the lamination stack 102. Accordingly, there are no over- : .
hanging pieces, arms, legs, or supports which infringe on the winding slots 109 or 110 or the armature cavity 10~ which would complicate the molding o~ the terminal board 115 and~or possibly 20. inter~ere with the winding of the coil 120. Since no part of the terminal board 115 extends beyond -the outer perimPter of the lamination stack 102, no special provision has to be made in the housing into which the sub-assembly is mounted.
When the structure of -the present invention is used ` with small motors, an auxiliary terminal board for supporting the brushes, which contact the armature, may be provided and projections ~rom the auxiliary terminal board may plug directly into one or more of the terminals 135 inserted into the terminal well 116 in order to make connections from the brushes to the 30- coil.
I~ conditions or circumstances are such as to make it expedient to do so, a terminal board 115 may be placed on ~6~
l- both sides of the lamination stack 102. However, under normal conditions onl~ one terminal board would be us d. The Eact that the terminal board comprises a single piece includiny the terminal wells 116, the arms 117, the ribs 118 an~ the wings ll9, there is only a single piece to be placed in position on the lamination stack 102, this will provide a simpler and more economical assembly. The cost of assembly is further reduced because the coil ends can be retained in their proper position prior to the insertion of the -terminal lO- 135 and the terminal 135 does not have to be inserted at the coil winding stationO
~ hile there has been shown and described what is considered at present to be the preferred embodiment of the invention, modifications thereto will readily occur to those skilled in the related arts. For example, the terminal board could be modified for use with a transformer stack, a solenoid or other assemblies including a coil windin~. It is believed that no further analysis or description is required and that the foregoing so fully reveals the gist of the present in-20- vention tha-t those skilled in the applicable ar-ts can adapt it to meet the exigencies of their specific requirements. It is not desired, therefore, that the invention be limited to the emhodiments shown and described, and it is intended to cover in the appended claims all such modifications as fall within the true spirit and scope of the in~ention.

Accordingly, the next stage of production usually requires a manual operation wherein a worker must manually tighten the loosened turn, or turns, and apply some form of tape or harness to retain the individual turns in the desired position. In addition, it is common practice to manually strip the end of the wound wire of its enamel insulation and connect a heavier duty flexible wire to facilitate making external connections.

20. Description o~ the Preferred Embodiment -~ he invention disclosed herein relates to a terminal board and the manner in which it may cooperate with a sub-assernbly on which a coil is to be wound such that the terminal board is retained on the sub-assembly by a first means before the coil is wound and wherein the terminal board is retained by a second means after the coil is wound. The terminal board includes means for capturing and re-taining the ends, and/or taps, of wound coils. The invention also discloses a termlnal means for providing electrical continuity be~ween the coil 30- ends and external leads. While the invention disclosed herein may find utility in a wide variety of applications including transformers~ relays and inductances, it is disclosed more 1. specifically with respect to a small universal motor.
Considering now more speciEically Figs. 1 and 2, there will be seen therein a sub-assembly illustrated generally as 101 comprising a lamination stack 102 held together by a pair of rivets 103. The lamination stack 102 also has holes 105 which may extend through the entire lamination stack 102 or which may penetrate only a portion of the lamination stack 102 depending upon the s~ecific means which may be used for mounting the sub-assembly in a housing (not shown). The lami-10. nation stack 102, as viewed in Fig. 1, is generally circular incross section and includes a pair of pole pieces 106 and 107 through which magnetic ~lux is directed across an armature (not shown) which is subsequently placed in the cavity 108. In order to generate the magentic flux, coils will be wound in the pairs of winding slots 109 and 110. Machines for efficiently and expeditiously winding coils in the winding slots 109 and 110 are well known.
Moun-ted on the lamination stack 102 is a terminal board illustrated generally as 115 and comprising a plurality 20. of terminal wells 116 which are shown in some addi~ional detail in Figs. 3 and 4. The terminal board 115 has arms 117 which ; extend from the terminal well area and follow the general out-line of the lamination stack including the winding slots 109 and 110. The arms 117 terminate in ribs 118 which join wings ` 119.
Prior to the winding.of.the coils in the winding slots 109 and 110, it is conventional to place insulating slo-t : liner in the slots 109 and 110~ In order to avoid confusion in the drawing, such slot liners have been omitted since their use 30- is conventional and well known. When the coil 120 5not shown ; in Figs n 1 and 2/ but shown in Figs. 3 and 5~ is wound in the ~: winding slots lOg and 110, the individual turns thereof make : _5_ .~

1. physical contact wi-th the ribs 118 and help to :re-tain the ter-minal board 11~ on the lamination s-tack 102. The wings 119 serve to retain the coil 120 away from the armature cavity 108.
The terminal board 115 includes a pair of bosses 121 which extend into the mating hoLes 105 as a press fit and retain the terminal board 115 on the lamination stack 102 prior to the winding of the coil 120 in the winding slots 102 and 110. As will be seen later, the bosses 121 may be knocked off after the terminal board 11~ is retained in its position by the coil 10. 120. The bosses may have holes lO~o As may be seen more clearly in Fig. 3, each termlnal well 116 is generally rectangular in cross section and has "Y"
shaped slots 126 in opposite walls 127 and 128 of the terminal wells 116. The base 1~9 of the Y slo-t 126 is proportionecl so that it will snuggly grasp and re-tain an end 130 of coil 120.
That is., the base 129 of the slot 126 has a width which is approximately equal to the diameter of the wire 130 which is an end, or center tap, of the wire of the coil 120.
When the coil winding machine (not shown) starts 20. winding a coil, the starting end 130 of the coil is laid into one of the Y slots 126 of one of the terminal wells 116 and urged towards the base 129. If the coil 120 has a center tap, a loop of wire will be brought out and urged towards the base 129 of another slot 126 of another well 116. When the coil 120 is fully woundrthe termi.nal end thereof, which will be simi-lar to wire 130 t will be laid into another slot 126 and urged to the base 129 thereof in yet another terminal well 116. Sub-se~uent to this placement of the coil end, the end 130 will be severed from the supply spool. The snug fit between the coil 30- end 130 and the base 129 of the slot 126 will retain the coil end 13Q in position and prevent the loosening of the last few turns of the coil 120. This re.tention of the coil end and ' - : . . . ~ . . . .
lo maintenance oE the inkegrity of the winding 120 e:Liminates the need Eor a subsequent manual opera-tion to snug up the last Ee~
turns of the winding 120 ancl the use oE auxlliary means for re-tainin~ the Eorm of the winding 120.
Considering now more specifically Figa ~ which con-stltutes a cross section oE the terminal well 116 taken throu~h the center oE the Y slots 126, it will be observed that at the base of the well 11~ there is an anvil 132 which is generally circular, or oval, (as seen in Fig. 1) and whose top sur~ace is 10. slightly below the base 12~ of the slots 116n It will al.so be observed from FigO 4 that the base 129 of the Y slot 126 in outer wall 128 is stepped with the lower level Eacing the in-terior o~ the well 116. The function of this step will be de-scribed more fully hereinaEter in connection with the descrip-tion of the insertion of the terminal 135 into the terminal well 116.
Upon completion of the sub-assembly 1019 including wind-ing the coil 120 and laying the coil ends and taps into slots 126, the assembly may leave the winding station and proceed 20- to the terminal installation station. As the sub-assembly 101 is conveyed from the winding station to the terminal in-stallation station, there is no tendency Eor the ends of the coils 120 to loosen inasmuch as they are securely retained with-in the ~ase 129 of the Y slots 126. The coil ends 130 protrude beyond the ou~er wall 128 of the terminal wells 116 and the wire 130 has enamel insulation thereonO The sub-assembly 101 is automatically oriented and posi-tioned at the terminal inserting station so that terminals 135 may be automatically inserted into any or all oE the terminal wells 116 wherein i-t is desired to have a terminal 135~ Generally spea]~ing~ -the outer dimensions of the terminal 135 are such as to constitute a secure :Ei-t into the terminal well 116n In addition, the terminals 135 may be ~ ~6~
1. equipped with serrations 136 which coact wi-th the interior surfaces of the well 116 to securely retain the terminal 135 within the confines oE the well 116 subsequent to the insertion of the terminal 135 into the well 116. That is, the serrations 136 are oriented to permit insertion of the terminal and resist removal thereof. That is, the serrations 136 di~ into and em-bed themselves in the plastic material of which the terminal board 115 is Eabricated. The terminal 135 will be seen to ha~e a generally "U" shape, but with a member 140 extendin~ downward 10. from an upper arm of the U towards the interior base of the other arm of the U. Thus, the terminal 135 is seen to comprise a single piece of metal shaped to form a first wall 137, a base 138, a second wall 139 and an interior member 1~0. The terminal 135 has a cut-away portion 141 which is relativaly wide in the base member 138 and narrows into slots 142 and 143 in the walls 137 and 139~ respecti~ely. The slots 142 and 143 are sized and shaped so that as the terminal 135 is pressed into the terminal well 116 these slots will engage the wire 130, pierce the enamel insulation on the wire 130 and make a good electrical contac-~
20. between the wire 130 and the terminal 135. The cut-away portion 1~1 in the base 138 allows the terminal 135 to s~raddle the anvil 132 as the terminal 135 is pressed into the terminal well 116.
As the slots 142 and 143 Eirst engage the wire 1~0, the portion of the wire 130 within the well 116 will be pressed down into contact with the upper surface of the anvil 132 and the base 12g of the slots 126. Further movement of the terminal 135 into the well 116 will cause the piercing of the enamel insulation already mentioned. In additionl prior to the full insertion of the ter-minal 135 into the well 116, the portion of the wire 130 which 30. e~tends outside the outer wall 128 will be sheered ofE by a means not shown. The final seatin~ of the terminal 135 within the well 116 will tend to draw the end oE the wire 130 towards the interior 1- oE the well 116. That is, the end of the w.ire 130 will not protxude beyond the outer sur~ace 128 oE the terminal board 115. This provides protection against accidental contact of the coil end 130 with a metal housin~ within which the sub-assembly 101 may be placed. The stepped shape at the base 129 of the ~ slot in the wall 128 assists in pullin~ in the end of the wire 130. When the terminal 135 ls fully inserted in the well 116, a portion of the wire 130 rests on the anvil 132. The wire 130 is also securely gripped within the slots 10- 142 and 143 of the terminal 135 to make good electrical contact therewith. If desired, the an~il 132 could include a slo-t having a width approximately equal to the wire diameter.
In order to make electrical connections from an ex-ternal power source to the coil 120, a wire 145 is inserted into -the terminal 135 as shown in Fig. 4. The stripped and tined end 146 of the wire 145 is securely retained within the terminal 135 by the sprin~ action of the interior member 140~
That is, the end 147 of the interior member 140 is positioned so close to the wall 137 that insertion of the wire end 146 20- therebetween will urge the end 147 of member 140 away from wall 137 and the spring tension Qf the interior member 140 will retain the wire end 146 in position. The shape and angle, of contact of the interior member 140 and the wire end 146 are such as to make it difficult to remove the wire 145 once its end 14~ has been inserted into the terminal 135. The anvil supports the wire 130 and prevents the insertion of the wire 146 from disturbin~ the wire 130. That is, the anvil 132 and the wire 13~ on it provide a down stop for the wixe end 146~
As previously mentioned, the terminal board 115 is first held on the lamination s-tack 102 by means of -the bosses 121 which press fit into the holes 105 (see Fi~s. 2 and 5~.
Subsequently, the windin~ of -the coil 120 over the ribs 11 _g_ - .
1. provides an alternate means for holdiny the terminal board in its position on the lamination stack 102. Accordingly, after the winding of the coils 120, the bosses 121 can be knocked off the terminal board 115. Therefore, if it is convenient or ex-pedient to do so to mount the assembly 101 to a frame or within a housing (not shown), a bolt 150 may be in<,erted into the holes 10~ of the -terminal board and forced therein to knock off the boss 121 of the terminal board 115 and push it through the holes 105 of ~he lamination stack 102 and discard it~ The bolt 150 10. can then be used to attach the sub-assembly 101 to a housing.
Because the terminal board 115 is first held on the lamination stack 102 by means o~ the bosses 121 interacting with the holes 105 and that the terminal board is later held by the coi.l 120 acting with the ribs 118, there is no need ~or any por-tion of the terminal board 115 to extend beyond the boundaries of the lamination stack 102. Accordingly, there are no over- : .
hanging pieces, arms, legs, or supports which infringe on the winding slots 109 or 110 or the armature cavity 10~ which would complicate the molding o~ the terminal board 115 and~or possibly 20. inter~ere with the winding of the coil 120. Since no part of the terminal board 115 extends beyond -the outer perimPter of the lamination stack 102, no special provision has to be made in the housing into which the sub-assembly is mounted.
When the structure of -the present invention is used ` with small motors, an auxiliary terminal board for supporting the brushes, which contact the armature, may be provided and projections ~rom the auxiliary terminal board may plug directly into one or more of the terminals 135 inserted into the terminal well 116 in order to make connections from the brushes to the 30- coil.
I~ conditions or circumstances are such as to make it expedient to do so, a terminal board 115 may be placed on ~6~
l- both sides of the lamination stack 102. However, under normal conditions onl~ one terminal board would be us d. The Eact that the terminal board comprises a single piece includiny the terminal wells 116, the arms 117, the ribs 118 an~ the wings ll9, there is only a single piece to be placed in position on the lamination stack 102, this will provide a simpler and more economical assembly. The cost of assembly is further reduced because the coil ends can be retained in their proper position prior to the insertion of the -terminal lO- 135 and the terminal 135 does not have to be inserted at the coil winding stationO
~ hile there has been shown and described what is considered at present to be the preferred embodiment of the invention, modifications thereto will readily occur to those skilled in the related arts. For example, the terminal board could be modified for use with a transformer stack, a solenoid or other assemblies including a coil windin~. It is believed that no further analysis or description is required and that the foregoing so fully reveals the gist of the present in-20- vention tha-t those skilled in the applicable ar-ts can adapt it to meet the exigencies of their specific requirements. It is not desired, therefore, that the invention be limited to the emhodiments shown and described, and it is intended to cover in the appended claims all such modifications as fall within the true spirit and scope of the in~ention.
