Grounding plate for orientationless squib connector assembly for automotive air bag assemblies
First Claim
1. A grounding plate for use in an automotive orientationless squib assembly having a single, centrally axially and upwardly extending initiator pin, the grounding plate comprising:
- an electrically conductive plate having a centrally located opening therein, the plate sized and configured to fit within a cylindrical socket of the squib assembly with the centrally located opening coaxially disposed about and spaced from the single, centrally axially extending initiator pin; and
a shorting member connected to the plate by a flexible hinge member and extending radially inwardly toward the centrally located opening to contact electrically to the single, centrally axially extending initiator pin when no external force is applied to the shorting member, the shorting member including an opening therein disposed to surround the single, centrally axially extending initiator pin, the opening generally aligned over the centrally located opening in the plate.

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.
