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.

Dependent claims

An environmentally sealed electrical connector assembly comprising:

a receptacle shell having a substantially cylindrical configuration including a profiled axial bore with at least one key extending therein;
a plug shell having a substantially cylindrical configuration having an external profile matable within said bore of said receptacle shell with at least one keyway recessed into the exterior of said plug shell and a profiled axial bore of like configuration to said profiled axial bore of said receptacle shell;
a socket insert having a substantially cylindrical external configuration adapted to be received in said axial bore of either of said shells and a plurality of terminal receiving passageways extending therethrough;
a like plurality of socket terminals each received in a respective passageway of said socket insert;
a pin insert having a substantially cylindrical external configuration adapted to be received in said axial bore of either of said shells and a like plurality of terminal receiving passageways extending therethrough;
a like plurality of pin terminals each received in a respective passageway of said pin insert;
polarizing means within the bore of each of said shells and on the exteriors of each said inserts allowing mounting of an insert in a respective shell with a specific orientation, said polarizing means including indicia at least on the faces of both said inserts to facilitate selection of the desired polarization;
means to environmentally seal rear end portions of each of said shells including a boot member engaging each conductor leading to a respective terminal, a rear gasket engaging a rear portion of said insert and having a planar portion with a plurality of bores, each receiving one of said boots therein in sealing engagement, and an integral annular sleeve portion;
compressive ring means engagable with the rear end of the respective shells and adapted to apply pressure to said gaskets with said planar portion forming a first seal between said gasket and each said boot member, a second seal between said gasket and the respective compressive ring and said sleeve portion forming a third seal between said shell and the respective insert received therein,
interfacial seal means providing sealing between mating face portions of said inserts;
and
annular sealing means providing sealing between the mated shells.
