Electrical Connection Locking Mechanism

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

Twin Terminal Locking Mechanism

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