The insert assembly that retains the contacts includes inserts (10) and (20) each having a plurality of passages (11, 21) having a respective contact (50) mounted therein and is characterized by a first and second plurality of resiliently and radially deflectable contact retention members (15, 25) arranged in face to face relationship in each of the passages (11, 21) the retention members (15, 25) having facing shoulders (16, 26) that retain the contact (50) by engaging the shoulders (52) and (53) of the enlarged portion (51) of the contact 50.

Abstract: A plurality of integrally molded fingers (21) extend outwardly and forwardly from the rear portion of a housing (20) to captivate an annular shoulder (11) of a coupling member (10) between the fingers (21) and an annular shoulder (22) on a housing (20).

Abstract: The invention is a plastic connector assembly characterized by a metal washer 10b, located between a wave washer 30 and the shoulder 21 of the connector housing 20. The metal washer 10 is further characterized by at least one projection 11 or 12 thereon which prevents relative motion between the metal washer 10b and the housing shoulder 21. This reduces the wear on the shoulder of the housing. Similarly to reduce wear on the shoulder in the coupling ring a second metal washer 10a may be placed on the other side of the wave washer 30 to accomplish the same purpose.

Abstract: The invention is a one piece molded electrical connector insert that snaps in to a connector housing without the need for additional mounting members or chemical bonding. The insert includes a plurality of resiliently and radially deflectable fingers 21 disposed around the outside of the insert and a second plurality of resiliently and axially deflectable fingers 22 also disposed on the outside of the insert 20 and adjacent to first plurality of fingers 21. The radial fingers 21 and axial fingers 22 completely fill a groove 15 in the inside of a connector housing 10 to prevent axial movement of the insert once it is mounted in the connector housing 10.

Abstract: The invention described is a plastic electrical connector characterized by a metal sleeve 20 mounted around the bayonet pin 12 coupling that projects from a connector housing 10.

Abstract: The invention is an electrical connector assembly characterized by a plurality of resiliently deflectable fingers (11) which extend between a shoulder 12 in the coupling ring and a shoulder 22 of the housing 20 to provide a bias between the coupling ring 10 and the housing 20 when the coupling ring 10 is completely threaded onto another connector housing. The fingers 11 may be integrally molded into either the coupling ring or the housing shoulder eliminating the need for an extra biasing member. The bias increases the force of friction on the threads in the coupling ring when it is fully mated to retard unwanted rotation, i.e., uncoupling.

Abstract: The invention described is a plastic electrical connector characterized by a coupling ring 1 having two elongated apertures 11 and 14, one of which 14 receives a pin 21 on another housing 2. The elongated aperture 11 allows the portion 16 between the apertures 11 and 14 to deflect when the pin 21 travels between recesses 15 in one side of aperture 14 thereby providing a bias against the coupling ring 1 that helps to prevent accidental uncoupling of the housings 2 and 3.

Abstract: This invention is an electrical connector assembly that prevents unwanted decoupling when this connector assembly is connected to another connector assembly. The first connector assembly is characterized by at least one resiliently deflectable and rearwardly extending projection 31 that mates with a notch 21 in the coupling ring 20 to prevent rotation of the coupling ring when it is connected to the second connector housing. An outer ring 10 is used to unlock the coupling ring and allow rotation when the coupling ring 10 is pushed forward against the coupling ring 20 and a forward projection 11 on the outer ring 10 enters the notch 21 in the coupling ring 20 and forcing the housing projection 31 out of the notch so that when the outer ring 10 is rotated the coupling ring 20 will also rotate.

Abstract: This invention provides a single core pin for use with a mold that may be rearranged to provide a plurality of molded configurations. The core pin is characterized by a plurality of arcuate segments 11 arranged to make up a cylindrical core pin 10. On at least one of the arcuate segments 11 there is along the outer surface thereof at least one radial projection 12 extending a predetermined axial distance along the surface.

Abstract: A socket contact is disclosed for miniature electrical connectors of the plug and receptacle type. The socket contact (10) comprises a contact sleeve (12) with two contact fingers (66) each extending as a cantilever beam from its root in the sleeve. A reenforcing ridge (68) in each finger extends from a point spaced from the free end of the contact finger to a point past the root of the finger to increase the stiffness of the finger. The radius of each finger and the location of the ridge thereon is such that the ridge is not engaged by a mating contact pin upon insertion into the socket.

Abstract: An electrical contact, for use in pin and socket type connectors, is fabricated as a unitary, composite body of metal and plastic. The contact (10) comprises a tubular body (12) having a wire receiving end (16) and a mating end (14). The composite tubular body (12) includes a sleeve (18) of wire cloth which is impregnated to form multiple islands (32) of plastic between the wires (34) on the internal surface and a plastic jacket (24) on the external surface. The contact fingers (22) are surrounded by a plastic hood (40) which provides a closed entry (42) for guiding a mating pin contact (44). The socket contact (10) is fabricated by stamping wire cloth to form a sleeve blank (18') and rolling the blank to form the sleeve (18). The sleeve (18) is fitted with core members (60) and (62) and placed in a mold cavity for injection molding of the plastic.

Abstract: One piece socket (1) or pin type (37) electrical contacts are stamped from a sheet of resilient, electrically conductive material and rolled into a tubular body (3) having a center section (11, 39) of enlarged diameter which functions as a C spring and is radially compressed to insert or remove the contact from either the front or rear of a bore (33, 41) in a connector (31, 45). An annular groove (17, 47) in the center section (11, 39) engages a retention ring (35, 49) in the bore (33, 41) to lock the contact (1, 37) in place and the center section (11, 39) bears against the wall of the bore (33, 41) to stabilize the connection. The resilient fingers (19) forming the socket type contact (1) taper inward and then flare outward to form a funnel (21) which guides the pin (53) of a mating pin type contact (37) into a narrow neck (55) in the socket where it is wiped clean and firmly gripped.

Abstract: An electrical contact 47 includes a tubular liner 1 stamped and rolled from a sheet of an electrically conductive material with an annular connector retention recess 13 provided in the external surface thereof between a mating end and a wire receiving end. One or more sleeves 21, 27 are telescoped over the liner 1 with at least one sleeve deformed in place into the annular recess 13. One of the sleeves 21 can be axially aligned preparatory to deforming it into the recess by an internal projection 25 which engages an annular groove 19 on the liner 1. A second sleeve can be axially aligned by lancing it to the liner 1 and by prick-punching the sleeve.
