Electrical connector with polarizing and grounding means

摘要

An electrical connector assembly includes a receptacle connector (4) having a housing (10) defining a generally rectangular mating receptacle (13). A polarizing recess (16) is formed in each of three corners of the generally rectangular mating receptacle. A plug connector (9) includes a housing (8) defining a generally rectangular mating plug for insertion into the mating receptacle (13) of the receptacle connector (4). A polarizing projection (35) is formed at each of the three corners of the generally rectangular mating plug corresponding in position to the positions of the polarizing recesses (16) of the receptacle connector (4) when the connectors are properly mated to prevent mating of the connectors in improper orientations. A U-shaped grounding clip (17) embraces a wall (42) of the receptacle connector (4) and includes a spring finger (17a) extending into the receptacle (13) for engaging the plug connector (9), along with a connecting portion (17c) outside the wall (42) for engaging a conductive fastener that mounts the receptacle connector to a chassis.
