Description

iiGr~(~uND .:~ND ~;UMMAR~' OF TilE :LNVENq'ION
The present invent:ion relates to a connector assembly for providing a swivelab]e quick connection.
In the automotive industry, as well as Lor many other industries, the need alwavs exists for low-cost, re]iable, and easy to assemble components. This need is especialLy apparent with respect to providing a connection between fluid carrving conduits, such as a fuel or re~rigerant lines.
In older threaded connectors, substantial assembly time could be accumulated in screwing on a cap to a fitting and tightening the cap down to the proper torque needed to provide for a fluid tight seal. Further, an inventory would have to be maintained to keep track of the number of caps and fittings~ and any liners or other components that may be necessary. Also, retightening of the caps may be required to maintain the seal after the automobile or other system has been put in use.
~ccordingly, it is the primary object of the present invention to provide an improved connector assembly for providiny a swivelable quick connection between fluid convey-ing conduits.
Broadly speaking the present invention provides a connector assembly for providing a swivelable quick connection, comprising: a tubular conduit adapted to convey fluid, having outwardly projecting annular surface means, formed at a predetermined distance from an end of the conduit to be connected, for providing a blockins wall portion disposed transversely to a central axis of the conduit; a housing having axial bore mean~ formed therein for receiving the conduit at a first end a~d for providing à fluid path at a second end; elastomerlc ri~g means disposed in the bore means ~r providinq a seal between the conduit and the housing;
annular bushing means disposed in the bore means for position-ing the ring means and for guiding the insertion of the conduit into a sealing engagement with the ring means; the hushing means cooperating with the bore means of the housing to impede further axial insertion movement of the conduit ~Z~;~26S
~ithill the hollsillg, the anllular surface means of -the conduit ju~taposed to the ~usliing means; and retaining means, demount-a~.ly coupled to t}le first end of the housing, for cooperating with the blocking wall portion of the annu].ar surface means to resist the disconnection of the conduit from the housing.

DETAILED DESCRIPTIO~ OF THE PREFERRED EMBODIMENTS

Referring to FIGURE l, a perspective assembly view of a connector assembly lO according to the present invention is shown. The connector assembly is generally comprised of a tubular conduit 12 adapted to convey fluid, ~Z~)3'~65 ~

a housing 14, and a ~etainer element 16. Conduit 12 is provided with an outwardly projecting annular surface 18 displaced from a beveled connecting end 20 of the conduit.
- Annular surfsce 18 is formed with a blocking wall ~ortion 22 disposed transversely or perpendicularly to a central axis 24 of conduit 12, and a sloping wall portion 26 grad-ually increasing fro~ an outer surface 28 of the conduit.
Housing 14 may have any suitable outer surface shape, and in one form of the present invention, the housing is provided with an enlarged diameter portion 30~ a reduced diameter portion 32, and a third diameter portion 34. The housing is adapted *o provide for apertures or openings 36 a-d, which are equidistantly spaced around the circumference of enlarged portion 30 of the housing. Apertures 36 are provided to receive and position retainer ~lement 16 transversely to axis 24 of the conduit. ~he retainer element ~s made from a resilient material, such as plastic, and is comprised of a pair of generally parallel elongated legs 38 joined at one end by a cross member 40, which provides a separation between the legs approximately equal to the outside diameter of conduit 12. Each retainer leg 38 in-cludes a sloping lead area 42 formed in the interior side of the leg, and a barb 44 projecting from the exterior side of the leg. In addition, each retsiner leg further in-cludes 8 first recess 46 and 8 second recess 48 formed iD
the front side of the leg.
Referring to FIGURE 2, a side elevation view of connector assembly 10 is 5hown, partially in cross-section, in a fully assembled position. Housing 14 i5 shown to be (i ~ lZ~;)3265'~`

formed with a central bore 50, ha~ing an enlarged diameter portion 52, n ~educed dihmeter portion S4, and 8 third diameter portion 56. Housing 14 also includes a buslling 58 and an elsstomeric ring 60 disposed in third diameter portion 56 of housing central bore 50. Bushing 58 also includes a flange portion 62, which extends into enlarged dia~eter portion 52 of ceDtral bore 50. A surface 64 of flange portion 62 i5 shaped to pro~ide a slope correspond-ing to sloping wall portion 26 of conduit 12.
In the preferred embodiment, connector assembly 10 may be connected by first coupling retainer element 16 to housing 14, and then inserting connecting end 20 of conduit 12 into central bore 50 of the housing. Retainer element 16 is coupled to housing 14 by inserting legs 38 into spertures 36a and 36b and QUt through apertures 36c and 36d until barbs 44 extend through apertures 36c and 36d. Barbs 44 projects outwardly a distance sufficient to engage *he upper edges of apertures 36c and 36d and pre-vent the removal of the retainer element from the housing.
Apertures 36 a-d are shaped sufficiently large to permit both an inward and outward deflection of retainer legs 38.
When retainer element 16 is being inserted into housing 14, the retainer legs deflect inwardly to permit barbs 44 to entend through apertures 36c and 36d. When connecting end 20 of conduit 12 is being inserted into bore S0 of housing 14, the retainer legs deflect outwardly to permit annular surface 18 to translate past the retaiDer logs.
Sloping wall portion 26 of annulsr surface 18 cooperates with sloping lead area 42 of retainer legs 38 to reduce ~ ? lZ032~5~ ~

the force required to translate the annular surf~ce pas~
the retainer le~s. After conduit 12 is fully inserted into central bore 50 of housing 14, as shown in FIGURE 2, ~etainer legs 38 cooperate with blocking wall portion ?2 of annular surface 18 to resist the disconnection or ~e-moval of conduit 12 from housing 14.
An important feature of housing 14 is elastomeric ring 60. This ring pro~ides a ~luid tight seal between conduit 12 and housing 14, and yet permits thç conduit to rotate or swivel relati~e to the housing. Ring 60 is positioned transversely to axis 24 of conduit 12 by bushing 58. Flange portion 62 of bushing 58 pro~ides a means for impeding further insertion of conduit lZ within central bore 50 when surface 64 of flange portion 62 contscts sloping lS wall portion 26 of annular surface 26 of the conduit.
Referring to FIGURE 3, another ~iew of connector assembly 10 is shown. Here, the connector assembly is illustrated in the "blced-down" position. This feature of the in~ention msy be used to safely disconnect conduit 12 from housing 14 when the fluid pressure is greater than ambient. Accordingly, retainer element 16 is par~ially removed or lifted up to the point where first and second recesses, 46 and 48 respectively, permit the retainer element to be translated toward a first end 66 of housing 14, in the direction of the arrows shown in FI~URE 2. Surfaces 68 and 7D of the retainer recesses will engaBe the vertical edges of apertures 36 ~-d adjacent to housing end 66, and prevcnt further axisl translation of retainer element 16.
Conduit 12 may then also be translsted toward housing end 66, ~ lZ03Z65 ~) past the point where elastomeric sing 6~ contacts conduit end 20. This will interrupt the fluid tight seal, and permit the pressure of the fluid to rapidly decrease.
When this seal is broken, legs 38 of retainer element 16 will prevent the total ejection of the conduit from the housing ~nder the force of the fluid pressure by engaging blocking wall portion 22 of annulas surface 18. After the fluid pressure has decTeased to the ambient pressure, the conduit may then be translated back toward 8 second end 72 of ~he housing, so that the retainer element may be removed. ~he condui~ may then be removed from the housing without any obstruction.
Referring to FIGURE 4, a second embodiment of a retaineT element 74 is shown. Retainer eiement 74 is similar to Tetainer element 16~ and the reference numerals for the corresponding components are the same. As in the case of retainer element 16, ~etainer element 74 is an integral element, formed in any conventional manner from a resilient material, such as plastic. The difference be-tween these retainers resides in the lead areas formed in the sides of legs 38. Retainer element 74 is formed with an annular outwardly extending lead area 76 in each of the legs. Lead areas 76 ha~e approximately the s~me thickness as the thickness of legs 38. Lead areas 76 may extend to the back surface of retainer element 74, or may only partially extend the widtb of legs 38, as shown in ~IGURE 4 ~t reference nu~eral 78. ln contrast, lead sreas 42 of retainer element 16 do not outwardly extend. Ra~her, lead areas 42 are recessed in the interior sides of legs 3~ for retsiner ... .

~ ZO 3~ ~ 3 element 16. Thus, the thickness of legs 38 for setainer element 16 is reduced at ~he fron~ surface of the legs, ~nd gradually increases to the normal leg thickness a~
the back surface.
RefeTring to FIGURE 5, a third embodiment of a r retainer element 80 is shown. Retainer element 80 is also intended for use with housing 14 shown in FIGURE 1.
Retainer element 80 is made from a resilient material, and is comprised of a pair of generally parallel elongated legs 82 joined a~ one end by a cross number 84, which is extended to form annulsr members 86. These annular mem-bers generally conform tD and partially encircle the outside surface of enlarge diameter portion 30 of housing 14. Annular members 86 are each formed with a barb 88 and a handle 90. Legs 82 are each formed with a lead area 92 similar in shape to lead area 42 for legs 38 of retainer element 16.
Retainer element 80 is coupled to housing 14 by inserting legs 82 into apertures 36a and 36b and out through apertures 36c and 36d. As legs 82 are being inserted, annular members 86 deflect outwardly to permit their trans-lation around the outside surface of housing 14. When the retainer element is fully inserted, barbs 88 will extend inwardly into apertures 36c and 36d to lock the retainer element in place. Handles 90 sre used to sssist the removal of retainer element 80 from housing 14, which is achieved by deflecting annular member 86 outwsrdly to disengage barbs 88 from the appertures and lifting the retsiner element out from the housing.

Referring to FIGURE 6, A fourth embodiment of a retainer element 94 is shown. Again, retainer element may be used with housing 14, and is made ~rom a resilient material. Retsiner element 94 is comprised of a pair of generally parallel elongated legs 96 joined at one end by a cross member 98. Legs 96 are each formed with an in-wardly extending barb 100, &nd a lead area 102 similar in shape to lead area 42 of retainer element 16. Retainer element 94 is coupled to housing 14 by deflecting legs 96 outwardly a sufficient distance to permit their insçrtion into apertures 36a and 36b and out through apertures 36c and 36d. When fully inserted, barbs 100 engage the lower lateral edges of apertures 36c and 36d to lock retainer element 94 in place.
Referring to FIGURES 7.and 8, retainer element 94 is shown coupled to a housing 104, similar in construc-tion to housing 14. FIGURE 7 is a front elevation view and FIGURE 8 i5 8. side elevation view partially in cross-section. Housing 104 is provided with an enlarged diameter portion 106 at & ~irst end 108 for receiving a conduit and for mounting retainer element 94, and a reduced diameter portion 110 at a second end 112 for providing a fluid path.
Housing 104 is also provided with a third diameter por-tion 114 interposed between enlarged diameter portion 106 snd reduced diameter portion 110. Housing lG4 further includes a bushing 116, two elastomeric rings 118 and 120, and an annular sleeve 122 for separating the rings.
This housing illustrates that more than one elastomeric ring mày be employed to provide a fluid tight seal, 85 may be required for the particular application of the con-nector assembly.

Referring to Figure 9, snother embodiment of a connector assembly 124 according to the present in-~ention is shown. This embodiment illustrates a housing 126 that may be employed to provide a fluid tight con-nection between a tubular conduit 12B and 8 metalllc tubular conduit 130. As in the case of conduit 12 of ~igure 1, conduit 128 includes an outwardly projecting annular surface 132, which is formed with a blocking wall por~ion 134 and a sloping wall portion 13~. Çonduit 130 is formed with an enlarged diameter portion 13~, which provides the third diameter portion of the abo~e described housings 14 and 104. Housing 126 is pro~ided with a bushing 140, an elastomeric ring 142, and a spacer 144 mounted in enlarged diameter portion 138 of conduit 130, Both bushing 140 and spacer 144 are made ~rom an electri-cally non-conductive material, sùch as plastic, and serve an important function when both conduits 128 and 130 are made from dissimilar metals subject to galvanic cor-rosion. Bushing 140 and spacer 144 support conduit 128 within housing 126 and preclude an end 146 of conduit 128 from contacting a reduced diameter portion 148 of conduit 130. Thus, where the fluid being conveyed is a liquid having the properties of sn electrolyte, bushing 140 and spacer 144 prevent the completion of a circuit loop which would allow 8 corrosion current to flow. Housing 126, as well as housings 14 and 104, may be made from either plastic or metal. Any of the retainer elements 16, 74, 80, or 94 may be coupled with housing 126 in the manner described above.
Referring to Figure 10, A fifth embodiment of a retainer element 150 is shown in relation to a conduit 152.

~Z~)3~65 ; 3 Retainer element 150 is comprised of two wedge shaped members 154 and 156~ which combine to form a jam fit against the bloc~ing wall portion (not shown~ of an an-nular surface 15B of conduit 152. Wedge member 156 5 . is comprised of a pair of generally parallel elongated legs 160 joined at one end by A cross member 162. Simi-larly, wedge ~ember 154 is comprised of a pair of generally parallel elongated legs 164 joined at one end by a cross member 166. Wedge member 156 further includes ~n out-wardly extending barb 168 formed at the end of eaoh o legs 160. Similarly wedge member 154 includes an out-wardly extending barb 170 formed in the side of each of legs 164. The sides of the legs 16D and 164 where wedge members 156 and 154 are joined are reciprocably slanted and formed with serrations, as indicated generally at reference number 172. Retainer element 150 may be coupled to a housing, such as housing 14 of Figure 1 to force annular surface 158 of conduit 152 securely against a bushing, such as bushing 58 of Figure 2. Retainer element 150 may be coupled to housing 14 by inserting legs 164 of wedge member i54 into apertures 36a and 36b, and in-serting legs 160 of wedge member 156 into apertures 36c snd 36d in a similar manner to that described above for retainer element 16. As the wedge members are being in-serted, the serrated edges of legs 160 and 164 engage and exert a further insertion force on conduit 152 via an-nular surface 158. After the wedge members are fully inserted, the serrated edges of legs 160 and 164 fixedly hold the wedge members in their relative positions. It of course should be appreciated by one skilled in the art that conduie lS2 may be inserted into hsusing l4 before the wedge members are coupled to the housing.

3265 ::j Referring t~ Figures 11 and 12, anotheT embodi-ment of a connector ~ssembly 174 according to the present invention is shown. Fi~ure 12 illustrates a perspective view of a retainer element 176, snd Figurc 11 illustrates n side elevation view, parlially in cross-section, of the fully assembled connector assembly. Connector assembly 174 is comprised of a tubular conduit 178, a housing 180, and retainer element 176 Housing 180 ~ay be made from any suitable material, such as plastic or metal, and may have any appropTiate outer shape, such as a cylinder or hex cons~ruction. Housing 180 is formed wi~h a central bore 182, which provides an enlarged diameter portion 184, a reduced diameter portion 186, and 8 third diame~er portion lB8. Housing lB0 further includes an inwardly extending flange 190, forming a forth diameteT portion, for mounting retainer element 176 to the housing. ~lange 190 may have a slant shape 85 shown in Figure 11 or may have a flat surface. Housing 180 is also provided with a bushing 192, two elastomeric rings 194 snd 196, a 2D sleeve l9B, and a spacer 200 generally mounted in third diameter portion 188. Retainer element 176 is made from a resilient material, and is comprised of a pair of op-posing annulhr leg members 202 and 204 centrally joined by a recessed ring 206, which positions the retainer element at flange 190 of housing 180. Annular leg 202 is formed with a radially extending tab end 20B on one side of recessed ring 206 and a radially converging jaw end 210 on the other side of the recessed ring.

Retain~r element 176 is coupled to housing 180 by insert;on into centrsl bore 182 until flange 190 engages or strsddles rec~ssed ring 206. Conduit 178 is then inserted into centrsl bore - 182 with an insertioD force sufficient to deflect ~on~er-ging jaw ends 210 and 214 outwardly to permit an snnular surface 216 of the conduit to be translated passed re-tainer element 176. After conduit 178 is fully inserted into housing 180, converging jaw ends 21D and 214 of re-tainer element 176 cooperate with a bloc~ing wall portion 218 of annular surface 216 to resist the disconnection or removal of conduit 178 from the housing. Conduit 1?8 may be remo~ed from housing 180 by compressing extending tab ends 208 and 212 together suffic'iently to extend conver-~ing jaw ends 210 and 214 apart, so that the conduit may be extracted from the housing without having to remove retainer element 176.
Referring to Pigure 13, another embodiment of a retainer element 220 for the connector assembly of Figure 11 is shown. Retainer element 220 is made from a resilient materisl, and is comprised of a ring 222 for mounting the retainer element on flange 190 of housing 180, a pair of opposing jaws 224 and 226 projecting from one sid0 of the ring, and a pair of tabs 228 snd 230 projecting from the other side of the ring ~nd positioned on opposite sides of the jaws.
