An orientationless squib connector assembly (,) for automotive air bag assemblies is disclosed. A single initiator pin (,) is provided axially aligned within a squib socket (,). An annular ground plate (,) surrounds the initiator pin (,) 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.

Grounding plate for orientationless squib connector assembly for automotive air bag assemblies

An orientationless squib connector assembly (10) for automotive air bag assemblies is disclosed. A single initiator pin (24, 326) is provided axially aligned within a squib socket (12, 324). An annular ground plate (28, 328) surrounds and shunts to ground the initiator pin near the base of the socket. An associated connector (16, 202, 312, 410) includes a first, axially located terminal (64, 280, 314, 416) for electrical contact with the initiator pin and a second terminal (66, 282, 316, 418) comprising a depending leg or beam (110, 320) radially aligned with the first terminal for electrically contacting the ground plate at any rotational orientation of the connector with respect to the socket and for moving a part of the ground plate (28) out of electrical engagement with pin (24). Eliminating a required rotational orientation of the connector simplifies its manufacture and assembly and its incorporation into a vehicle. Preferably, the entering wires, surrounded by a ferrite block (84), are also axially aligned with the first and second terminals. CPAs (72, 322, 420) may be used to prevent unlatching of the connector assembly. Closure of the CPA may be prevented by a blocking feature on the associated connector that is automatically displaced when the connector is properly engaged in the socket.

A high density electrical connector is provided for supporting a plurality of contact assemblies in a geometric array, each contact assembly comprising a conductive contact portion, a retention portion, a vertical offset portion and a conductive connection portion. The contact portions are disposed in side by side positions along n rows across the connector. An insulative housing is provided having a rear wall, a forward wall and a plurality of contact assembly support cavities extending between the rear and forward walls. Each support cavity has a contact retention rib which engages the retention portion of the contact assembly. Each support cavity also has an elongate contact entry opening in the rear wall, the entry openings being disposed along n pairs of rows in a staggered array, with adjacent cavities in each pair of rows being alternately upright and inverted. The entry openings for upright cavities in a pair of rows lie along a first center line. The entry openings for inverted cavities lie along a second center line offset from the first center line by a distance less than height of the contact entry openings such that the inverted and upright cavities in each pair of rows are interleaved.
