Abstract
Abstract An electrical connector assembly is disclosed having the capability of being field repairable as well as being assembled in a plurality of configurations by appropriate selection of parts. The assembly includes mating plug and receptacle shells, a pin insert and a socket insert each capable of being received in either shell aligned in a selected one of a plurality of positions and a mating socket terminal and pin terminal each being mountable in either said socket or said pin insert. The connector assembly further includes rubber boots to enclose conductors leading to the respective terminals as well as a rear sealing gasket making a sealing engagement between a respective pin or socket insert and the sealing boots, and the respective socket or plug shells. The connector assembly also includes a compression ring for applying compression to the sealing gasket to effect the sealing engagement, a compression cone providing rear gasket compression, strain relief for the conductors, interfacial seals, and a spring loaded coupling ring. The above itemized parts can be arranged in any one of a number of configurations according to the particular local needs with the entire assembly being such that it can be easily disassembled for repair in the field without requiring the use of extensive and particularized tools.
