  • a device CPA can serve on the one hand to cause a tension of the locking spring during a phase of contact or approach of a coupling of the connector with a counter-connector, and of on the other hand to ensure the maintenance of the main locking of the connector when it is correctly coupled to the counter-connector.

  • the spring in the state of delivery: the spring can be essentially relaxed or is in any case with a minimum tension with respect to a loaded state in which the spring is pushed back, and therefore stretched or loaded, by the deflection of the connector position insurance element; the position assurance element of the connector is in its initial position which is its default position at rest before coming into contact with a contact surface of the counter-connector during a coupling, or just in contact with this one; and said at least one main locking element, which can be deflected during a coupling, is in its non-deflected position which, when the connector is correctly coupled to the conjugate connector, provides the main locking, for example between a pyrotechnic connector and a conjugate lighter support.

It is therefore possible to combine the above advantageous effects with a CPA device that can be configured for, in the loaded state of the connector and once the CPA device sufficiently moved by a push against the counter-connector during a coupling, can allow the deflection of the main locking element of the connector, allowing then to pass to a properly locked state of the connector with the counter-connector if the mating is continued.
  • the locking lances or lances of a pyrotechnic connector can be deflected in a loaded state, allowing then to continue the insertion of the pyrotechnic connector into the lighter carrier. Once the connector is properly inserted into the igniter holder, the locking lances can return to their delivery position, then snapping into spaces provided in the lighter bracket and thus achieving the main lock with it.
  • the invention is advantageous with respect to the pyrotechnic connectors known from the state of the art because the tension of the loaded spring allows: when the connector is not fully and correctly inserted into the counter-connector, to eject automatically the connector by performing a reverse thrust of the connector position assurance element on a contact surface of the counter-connector; or, when the connector is properly inserted into the counter-connector, automatically return the connector position assurance element to its delivery position, thereby preventing deflection of the main locking element (s), thereby maintaining lock.
