A device and method facilitates grounding shielding, including hardware and structures necessary to allow proper connection, practice the steps of the method, minimize pigtail length, facilitate the formation of a wire bundle assembly, facilitate repair and installation, and result in materials and labor savings.

Shield grounding connector and method

A mechanical interlock system using ball detents for interlocking the first and second connector halves of an electrical connector assembly. In the preferred embodiment, two ball detents are utilized. The first connector half, or plug member, has recesses for receiving ball detents secured in the second connector half, or receptacle member. Slots are formed in each of the side walls of the receptacle member, each ball detent being positioned in an aperture formed between the slot and a receiving area in the receptacle member. A first portion of the surface of the ball detent extends into the slot and a second portion of the ball surface extends into the receiving area, the ball detents being secured in the aperture by a preloaded spring washer positioned in each slot. The second surface portion of each ball detent enters the recesses when the plug is inserted into the receptacle area thus forming the mechanical interlock.

Connector mechanical interlock using ball detents

An electrical connector assembly having first and second electrical connector halves. Coupling and decoupling is accomplished by a coupling nut mounted on the first electrical connector, the coupling nut having a screw thread adapted to receive a screw thread on the second connector. The first electrical connector half includes an annular recess formed about its circumference. A belt member having a plurality of resilient protrusions formed thereon is positioned within the annular groove. A split-ring member having inner and outer circumferences is then positioned about said belt type member in a manner such that ratchet teeth formed on the inner circumference of the split ring can engage the protrusions on said belt member. In one embodiment, the outer circumference of said split-ring member has plurality of apertures formed thereon, the apertures being aligned with apertures formed in the coupling nut. Fastening members positioned through the co-lined apertures join the coupling nut to the split-ring, the split-ring being rotatable with the coupling nut. The fastening members integrally join the coupling nut to the first electrical connector via the split-ring thus preventing the coupling nut from being removed from the electrical connector due to any vibration or other type of disturbance. The serrations on the inner circumference of the split-ring interact with the protrusions to provide an anti-rotation feature such that coupling may be accomplished with less effort whereby a greater resistance is provided to decoupling.

Self-locking coupling nut

A plastic electrical connector member is disclosed having bayonet pins thereon adapted to engage bayonet slots on a coupling nut of a mating connector member. The bayonet pins are formed on a metal band which surrounds the plastic body of the first connector member. The pins are hollow and filled with a molding compound which is integral with the plastic body so that movement of the bayonet pin band on the plastic body is prevented.

Bayonet coupling for electrical connector

A bayonet coupling nut is disclosed in which a metal element having at least one bayonet slot formed therein is mounted within a cylindrical nut body. The body may be formed of metal or plastic, and the bayonet slot-forming element is formed from a stamped sheet metal strip or a suitably formed wire. The element is inherently resilient, thus eliminating the need for a separate wave spring as in prior bayonet coupling nuts.

Bayonet coupling nut

A unitary one-piece electrical connector body is disclosed having an outer shell portion surrounding an inner insulator portion. The outer shell portion is formed of an insulator containing a conductive filler. The connector body is formed by a double shot molding process using a single cavity mold.

Electrical connector body and method of making same

A radio frequency and electromagnetic shield for an electrical connector comprising a spring band which is interposed between the mating halves of the connector. The band is formed from a sheet of resilient metal which is lanced to provide alternating slits which open at opposite edges of the band. The band is expanded over the male half of the connector so that the slits open, providing therebetween spiraled spring arms. When the mating halves are connected, the band is radially compressed causing the spring arms to untwist thereby closing the slots in the band.
