SRS Air Bag Special Connector

GENERAL INFORMATION

SRS AIR BAG SPECIAL CONNECTOR





To enhance the system reliability, a connector short circuiting mechanism is integrated in the SRS-ECU connector, air bag module connectors, clock spring connector, pre-tensioner connectors, and intermediate connector between curtain air bag module and SRS-ECU (black connector "A" shown in the figure).

SQUIB CIRCUIT CONNECTOR LOCK SWITCH





This mechanism prevents the improper deployment of air bag module because of the current application to the squib due to the static electricity when connectors between SRS-ECU and air bag modules
(squibs) are disconnected. When the connector is disconnected, the short spring short circuits the power supply side terminal and ground side terminal of squibs, and prevents the static electricity from generating the potential difference. This connector mechanism is adopted for the following connectors.

- SRS-ECU connector
- Connector between the clock spring and body-side wiring harness
- Each air bag module connector
- Each pre-tensioner connector
- Intermediate connector between curtain air bag module and SRS-ECU
