SRS Connectors

SRS CONNECTORS





All connectors in the SRS are colored yellow to distinguish them from other connectors. Connectors having special functions and specifically designed for SRS are used in the locations shown below to ensure high reliability. These connectors use durable gold-plated terminals.





1. Terminal Twin-Lock Mechanism

Each connector has a two-piece construction consisting of a housing and a spacer. This design secures the locking of the terminal by two locking devices (the spacer and the lance) to prevent terminals from coming out.





2. Airbag Activation Prevention Mechanism

Each connector contains a short spring plate. When the connector is disconnected. the short spring plate automatically connects the power source and grounding terminals of the squib.

HINT: The illustration shows connectors (3) and (4). Connector (1) has a short spring plate on the female terminal side, but the operating principle is the same.








3. Electrical Connection Check Mechanism

This mechanism is designed to electrically check if connectors are connected correctly and completely. The electrical connection check mechanism is designed so that the connection detection pin connects with the diagnosis terminals when the connector housing lock is in the locked condition.





4. Connector Twin - Lock Mechanism

With this mechanism the male and female connectors are locked by two locking devices to increase connection reliability. If the primary lock is incomplete, ribs interfere and prevent the secondary lock.
