  • Damaged contact housings must always be replaced. New contact housings may be ordered via OTC Kassel.
  • Small screwdrivers may be used as an aid to release the secondary locks.
  • Chamber/pin assignment is located partially stamped in on secondary lock or rear side of terminal housing.
  • Detailed information on component locations of harness connectors.

The allocation of the correct release tools to the respective locking mechanisms can be found in the table in the Release Tool Set -VAS1978/35- Operating Instructions.

Secondary Lock

The secondary lock is a housing securing mechanism (second locking mechanism) that secures all wires in one contact housing. If a secondary lock is installed at a contact 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.
