Abstract
A keying arrangement for electrical connectors is disclosed for preventing the inadvertent mating of a plug to the wrong receptacle. The opposing ends of the mating plug (14) and receptacle (12) have polygonal openings (80,94) formed completely through their housings that contain opposing polygonal-shaped keys (100) that are axially aligned. Each of the keys is retained in its respective polygonal opening by a pair of wing-like flanges (116) extending from the key that overlies a first surface (86) formed in the housing adjacent the polygonal opening and a locking tab (122) projecting from the key that underlies another surface (92) spaced from the first surface (86).
