FIG. 5 is a sectional view of the plug taken along line 5-5 of FIG. 4.
Referring to the drawing and FIGS. 1, 2, and 3 in particular, the connector of this invention comprises a socket 10 and a plug 12 adapted to be inserted into the socket and make electrical connection therewith.
The socket 10 includes a base 14, a pair of side walls 15 upstanding from the base, and a support 16 extending between the side walls parallel to and a preselected distance from the base. The support 16 has a rear wall 18 depending therefrom and the support and rear Wall in conjunction with the base 10 and the side walls 15 define a rectangular cavity 20.
The support 16 is formed of a dielectric material, and it has a plurality of parallel channels 22 therein that extend perpendicular to the entrance of the cavity 20. As shown most clearly in FIG. 2, each channel 22 extends through the support 16 in an offset fashion to provide a portion that faces the interior of the cavity 20 and a portion that faces the exterior of the cavity. The interior portion of each channel 22 extends from a point adjacent to the rear end of the support 16 to a point intermediate the front and rear ends, while the exterior portion of each channel extends from a point intermediate the front and rear ends of the support to a point adjacent to the front end.
A plurality of spaced slots 24 also extend through the support 16, the slots being located in a row adjacent to the rear end of the support. Each slot 24 is aligned with an individual channel 22, and each channel and associated slot accommodates a contact member 25.
Each contact member 25 includes a stop portion 26 at one end thereof, a terminal portion 28 at the other end thereof, and a contact portion 30 intermediate the stop and terminal portions. The stop portion 26 is positioned within the exterior portion of the channel 22 and is biased toward the support. 16, the bias being due to deformation of the contact member 30 at the junction of the contact portion 30 with the terminal portion 28. The contact portion 30 is nose-shaped, and when the stop'portion rests on the support 16, the contact portion protrudes from the interior portion of the channel '22 into the cavity 20. The terminal portion 28 of each contact member 25 extends through the slot 24 from the interior portion of the channel 22 to the exterior side of the support. The terminal portion 28 is staked in the slot 24 to secure the contact member 25 in place, and the exterior end of the terminal portion is adapted to be secured to a conductor (not shown) by soldering or wire Wrapping. Since the support 16 is made of a dielectric material, each of the contact members 25 and thereby the conductors secured to the contact members are electrically insulated from one another.
The socket further includes a. front piece 32 at the forward end of the cavity that extends parallel to the support 16. The front piece 32 includes a ridge 34 along one edge thereof and a groove 35 that extends through the ridge transverse thereto.
Referring now to FIGS. 1-, 4, and 5, the plug 12 includes a rectangular dielectric housing that is of substantially the same height and width as the cavity 20 of the socket 10, the housing comprising a support 42 and a cover 44. The support 42 has a plurality of spaced parallel channels 45 in the side thereof facing the interior of the housing 40, the channels corresponding in number and spacing to the channels 22 and the support 16 of socket 10. The channels 45 extend perpendicular to the forward end of the housing 40 from a point adjacent to the forward end to a point intermediate the forward and rearward ends thereof.
A slot 46 extends through the support 42 at the forward end of each channel 45 and a slot 48 extends through the support at the rearward end of each channel, the forward edge of each slot 48 being beveled. In addition, a ridge 50 protrudes from the exterior side of the support 42 rearward of the slots 48, the ridge 50 extending generally parallel to the forward end of the support.
Finally, a wall 52 protrudes from the interior side of the support 42 and a recess 54 is located on both the forward and rearward sides of the wall. The wall 52 and recesses 54 are intermediate the slots 48 and the rearward end of the support 42, and as seen most clearly in FIG. 5, the wall and recess extend briefly on each side of the longitudinal axis of the support, a hole 55 extending through the support adjacent to each end of the wall.
The cover 44, which couples with the support 42 to form the housing 40, includes a front wall 56 projecting from the forward end thereof and a pair of recesses 58 and 60 in the side thereof facing the interior of the housing. When the cover 44 is properly positioned on the support 42, the front wall 56 extends in front of the forward end of the support 42 while the recess 58 is in juxtaposition with the channel 45 and the recess 60 is in juxtaposition with the wall 52 and the recess 54 of the support. In addition, when the cover 44 is properly positioned on the support 42 the cover has a pair of spaced holes therein (not shown) that are in registration with the holes 55 in the support.
A plurality of contact members are mounted on the support 42 of the housing 40, the contact members 62 corresponding in number to the contact members 25 of the socket 10. Each contact member 62 includes a hook portion 64 at one end thereof, a terminal portion 65 at the other end thereof and a contact portion 66 intermediate the terminal and hook portions. Furthermore, each contact member 62 has a U-shaped configuration, it being bent back on itself intermediate the terminal portion 65 and the contact portion 66.
Each contact portion 62 is positioned on the support 42 with the hook portion 64 engaging the beveled forward edge of the slot 48, with the contact portion 66 extending along the exterior side of the support parallel to and above a channel 45, with the bend in the contact member extending through the slot 46, and with the terminal portion 65 positioned within the channel beneath the contact portion.
The terminal portion 65 is advantageously of the insulation piercing type whereby the terminal is electrically connected to an insulated conductor 68 in the process of being crimped thereabout. The insulated conductors 68, which are themselves advantageously encased within a dielectric sheath to form a cord 70, enter the housing 40 through a grommet 72 mounted to the rear end of the housing, the grommet comprising a flexible portion 74 and a rigid portion 75.
flexible portion is flush with the forward face of the middle flange. The flexible portion 74 and the rigid portion 75 are thereby affixed together. The forwardmost flange of the rigid portion 75 is accommodated by complementary grooves in the support 42 and the cover 44, and when the forwardmost flange is so situated, the forward face of the middle flange and the flexible portion 74 The rigid portion of the grommet 72 has three flanges i spaced along the length thereof, and the flexible portion 74 is molded thereabout so that the forward face of the butt against the rear end of the support and cover. Consequently when the support 42 and cover 44 are fastened together to form the housing 40, the grommet 72 is captured and held securely to the rear end thereof.
In addition, when the support 42 and cover 44 are fastened together the cord 70 is forced to follow a tortuous path to get around the wall 52 of the support, the cord proceeding from the rearward recess 54 in the support, into the recess 60 in the cover, and then into the forward recess 54 in the support. This arrangement prevents tension on the cord 70 from being transmitted to the terminal portions 65.
The support 42 and cover 44 are fastened together by means of rivets 76, the rivets extending through the holes 55 in the support and the holes in the cover in registration therewith. The rivets 76 also secure one end of a spring detent 78 to the exterior surface of the support 42, the other end of the detent being normally spaced from the support.
As the plug 12 is inserted into the cavity 20 of the socket 10, the contact portions 66 of the contact members 62 on the plug engage the contact portions 30 of the contact members 25 in the socket and deflect the contact portion 30 upward. Further movement of the plug 12 into the cavity thereafter results in a rubbing together of the two contact portions 30 and 66. This movement of the two contact portions 30 and 66- against one another, together with the contact force generated by the deflection of the contact portion 30, provides a good electrical connection between the contact members 25 and 62.
In addition, as the plug 12 is inserted into the cavity 20 of the socket 10 the free end of the detent 78 is deflected downward by the ridge 34 of the front piece 32. Then when the plug 12 is fully inserted into the cavity 20, the free end of the detent 78 moves behind the ridge 34 and latches the plug into the cavity. To remove the plug 12 from the cavity 20 it is necessary to insert a stiff wire or similar implement through the groove 35 in the front piece 32, deflect the free end of the detent 78 below the crest of the ridge 34, and pull on the plug.
