Secondary Lock

Secondary Lock

The secondary lock is a housing securing mechanism (second locking mechanism) that secures all wires in one terminal housing. If a secondary lock is installed at a terminal housing, it must always be opened or removed using specified tool before releasing and pulling out individual crimp contacts.

Secondary lock is distinguished by a different color from the rest of the contact housing. It simplifies recognizing the secondary lock and clarifies its function.

The shapes of the terminal housings depicted here are only a selection which, as an example, should make clear the various functions of the secondary lock.
