Abstract: An assembly for coupling a resilient electrical connector component to another mateable connector component includes a shell engageable about the resilient component. The shell includes a plurality of axially cantilevered, circumferentially spaced fingers at one end thereof which surround the resilient component, the fingers including means for defining a substantially rigid circumferential bearing surface thereabout. An annular coupling member is provided which is engageable with the bearing surface for rotation about the shell and includes means for attachment to the mateable connector component. The coupling member and the bearing surface means are configured and arranged such that the inherent elasticity of the resilient component maintains the coupling member and bearing surface in cooperative engagement.

Abstract: A clip for securing a detachable electrical plug and cable assembly in an electrical receptacle having a hinged cover plate. The clip has first and second body members; means for securement of the first body member to the electrical plug and cable assembly; means for rotatably attaching the second body member relative the first body member; and biasing means integral with the first or second body members for pressing an adapted end of the second body member against the outside suface of the cover plate and bias the cover towards a closed position such that at least a portion of the inside surface of the cover plate presses against the plug to secure the electrical plug and cable assembly against relative movement with the receptacle. The first and second body members of the clip are preferably made from metallic wire or plate, but may be made from polymeric materials or combinations of polymeric and metallic materials.

Abstract: A locking shield for an electrical terminal includes a base wall secured to an insulator body molded about a female terminal. Wing flanges extend from the base wall about the insulator body and include overlapping apertured terminal flanges which overlie an apertured wall of the body opening to the terminal. The terminal flange apertures are normally misaligned since the wing flanges are resiliently biased apart relative to each other. When the wing flanges are manually squeezed together, the apertures are aligned so that a male terminal can be inserted therethrough into electrical engagement with the female terminal. The resilient bias of the wing flanges engages the edges of the apertures with the male terminal to lock it in place when the wing flanges are manually released.

Abstract: A connector for a cable, hose or the like, which connector comprises a pin, a female portion having a collar, and a male portion having a ring of members which are adapted to move outwardly when the pin is pushed between a pair of the members and which are adapted to move inwardly when the pin is pulled out from between the pair of members, the members in the ring being effective to engage the collar in their outward position and so retain the male and female portions together, and the members in the ring being disengaged from the collar when they are in their inward position such that the male and female portions can separate.

Abstract: A removable pin-aligning insert is formed for positioning within a substantially tubular, pin isolating means of a cathode ray tube base. This insert assures positive alignment of the respective isolated tube connector pin within the tubular, pin isolating means from the time the base is applied to the tube until subsequent utilization.

Abstract: The invention is concerned with separable electric connection devices of the kind comprising two rigid supports fitting one inside the other, e.g. a printed circuit board and a connector therefor, one support carrying at least one primary contact member and the other carrying at least one resilient secondary contact member the free end of which is movable in a direction fixed relative to its support, and mechanical means for displacing one support relative to the other in the said direction after the supports have been fitted together, to make contact between the primary and secondary contact members. In the device of the invention the mechanical means is adapted to effect such a movement in the said direction followed by a supplementary movement in a direction perpendicular to the said direction which provides a self-cleaning action on the contacts.

Abstract: An apparatus for facilitating the coupling and uncoupling of electrical connectors. The apparatus includes at least one rack gear on the body of a first of a pair of electrical connectors and a pinion member on the other, engageable with the rack and having an actuating lever for rotating the pinion member. As the lever is moved in a first direction, the pinion rotates and engages the rack, pulling the two connectors together. When the lever is moved in the other direction, the connectors are pulled apart.

Abstract: There is provided a cylindrical connector shell for receiving electrical contacts. The shell includes an annular recessed ring having at least one ratchet tooth projecting upwardly from the surface of the ring. One side of the tooth has a greater angle of inclination with respect to the surface of the ring than the other side. A coupling nut is received over the shell for engaging the shell with another body such as a mating connector shell. The coupling nut has at least one member projecting away from the inner surface of the nut for periodically engaging the ratchet tooth. The coupling nut turns easier in one direction than the other because of the angle differences of the sides of the ratchet teeth. At least one slot is further provided in front of the annular recessed ring for fitting the projecting member of the coupling nut into the recessed annular ring. The slot is deeper at one end than the other for snapping the coupling nut into the recess and securing the nut to the shell.

Abstract: A battery connector clamp has a cooperating pair of solid lead jaws having abutting inner ends that clampingly encircle a battery post and having grooved outer side surfaces to seat the parallel shanks of a U-bolt with the threaded ends of the shanks being engaged by nuts so as to secure a clamping bar against the outer end of one jaw and in clamping cooperation with the bight portion of the U-bolt which is seated in a groove in the outer end of the other jaw that has a bore to receive the bared end of a conductor cable.

Abstract: An improved environmentally sealed connector is disclosed. The connector includes mating members having bodies of semi-rigid dielectric material with a plurality of contact receiving cavities therein. A like plurality of seals are provided each inserted into a recessed rear end portion of a respective contact receiving cavity to effect seating engagement with both the member and the wires connected to the terminals mounted therein.

The seals allow easy replacement of the contacts without destroying the sealing characteristics. The connector members also include radially deformable locking means and sealing means at the mating faces.

Abstract: An electrical connector having means for suppressing electromagnetic interference when the connector pins are separated from the pin sockets. To this end, each of the connector pins or each pin socket is contained in an electrically conductive housing. The housing forms an open space about and extending beyond each pin or socket. This open space forms a waveguide having a predetermined upper cutoff frequency. This cutoff frequency depends on the length of the waveguide measured from the tip of each pin or socket to the end of the waveguide and on the diameter or largest dimension of the waveguide, which may be a cylindrical waveguide. Each of the corresponding pin sockets has an outer insulation tube which fits into the open waveguide. Further, each pin socket is provided with a spring contact for making electrical connection to the respective connector pins. The cutoff frequency of the waveguide is selected to be substantially above the highest frequency of the expected electromagnetic interference.

Abstract: A coupling arrangement for mating electrical or optical connector subassemblies in which opposing coupling members are secured by a bayonet arrangement about their outer perimeters. Resilient (spring) fingers on at least one coupling member engage bayonet key-ways about the opposite member outer surface. The key-way and finger interface at the locked position is along at least one chamfered surface to permit the resilient fingers to deflect radially outwardly and "ride out" of the locked position to allow connector separation in response to excessive cable tension.
