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.
