Abstract
Abstract An orientationless squib connector assembly ( 10 ) for automotive air bag assemblies is disclosed. A single initiator pin ( 24 ) is provided axially aligned within a squib socket ( 12 ). An annular ground plate ( 28 ) surrounds the initiator pin ( 24 ) near the base of the socket. An associated connector includes a first, axially located terminal for electrical contact with the initiator pin and a second terminal comprising a depending beam radially aligned with the first terminal for electrically contacting the ground plate at any rotational orientation of the connector with respect to the socket. Eliminating a required rotational orientation of the connector simplifies its manufacture and assembly and its incorporation into a vehicle. Preferably, the entering wires are also axially aligned with the first and second terminals.
