Connector with removable unkeyed insert and removable unkeyed insert therefor

摘要

An unkeyed insert (4) removably retained in a electrical connector (2) has a mating portion (44) projecting from a forward face of the connector beside a mating structure (12) also projecting from the forward face of the connector (2). The mating part (44) defines a socket (60) for receiving a screw lock (234) on a mating connector (200). The mating part (44) has an open side (58) closely adjacent to the mating structure (12). By virtue of its rectangular shape, the mating part (44) can only be angularly oriented with its open side facing the mating structure (12). The unkeyed insert (4) cannot be mated with a keyed structure (218) of the mating connector (200) since an end face (62) of the mating part (44) would butt against the distal end of a rib (222) of the keyed structure (218).
