Abstract
Abstract An electrical connector assembly is formed of opposed hermaphroditically mating connectors, having two or more pairs of alternating male and female contact members. Each female contact member is carried by and disposed at the outer end of a linear elongated insulating member projecting from the end of the plug. The insulating members in cross-section are each in the configuration of a sector of a circle having a truncated central edge. The male contact members are disposed between the elongated insulating members. The elongated insulating members are so configured that when two of the connectors are mated together the elongated members will form a cylindrical shape. The connectors will mate together only in one orientation due to the fact that at least one of the elongated insulating members forms an arcuate part of the circumference of a circle that has a different length than at least one of the other elongated members. The connectors are protected from the environment in three separate ways, the position of the female contact within the elongated insulating members, a snap-in-place sleeve element that engages grooves on the outer surface of the plug members, and a shroud of heat shrinkable material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
An electrical connector assembly comprising opposed mating connectors, said connectors comprising substantially identical hermaphroditically mating plug members each of which has two or more pairs of alternating male and female contact members, each female contact member being carried by and disposed at the outer end of a linear elongated insulating member, each of said insulating member, in cross-section, being in the configuration of a sector of a circle with the central edge thereof being truncated in an amount sufficient to facilitate sliding together of the members, the male contact members being disposed between said elongated insulating members, the elongated members of two of said connectors, when mated together, forming a cylindrical shape, at least one of the elongated members on each plug member forming an arcuate part of the circumference of said circle of a different length than at least one of said other elongated members, whereby said plug can be mated together in only one orientation each plug being provided with a circumferential groove and a cylindrical protective sleeve having internal ridges engageable in said grooves being provided to envelope the connecting part of said plug assembly.
Claim 2
Dependent Claim
188 words
An electrical connector assembly comprising opposed mating connectors, said connectors comprising substantially identical hermaphroditically mating plug members each of which has two or more pairs of alternating male and female contact members, each female contact member being carried by and disposed at the outer end of a linear elongated insulating member, each of said insulating member, in cross-section, being in the configuration of a sector of a circle with the central edge thereof being truncated in an amount sufficient to facilitate sliding together of the members, the male contact members being disposed between said elongated insulating members, the elongated members of two of said connectors, when mated together, forming a cylindrical shape, at least one of the elongated members on each plug member forming an arcuate part of the circumference of said circle of a different length than at least one of said other elongated members, whereby said plug can be mated together in only one orientation each plug being provided with a circumferential groove and a cylindrical protective sleeve having internal ridges engageable in said grooves being provided to envelope the connecting part of said plug assembly.
