Method and contact latching system for temporary primary locking of electrical contacts in connectors

摘要

In a method for secondary locking of at least one electrical contact (2), which is plugged into a contact chamber (7) and is then primarily locked, the at least one electrical contact (2) is made in its contact chamber (7) by means of an external locking tool (12), which engages from the outside through a side wall opening (11) of the contact chamber outer wall (10) into the contact chamber (7), primarily latched, and then the electrical contact (2) is secondarily locked in its contact chamber (7) before the external latching tool (12) again Will get removed. The associated contact locking system for an electrical plug connection comprises at least one electrical contact (2) which has an undercut (6) for primary locking, a contact chamber housing (1) which has at least one contact chamber (7) for inserting the electrical contact (2), and at least one locking element (17) for secondary locking of the inserted electrical contact (2) against the mounting direction (3), whereby according to the invention a contact chamber outer wall (10) of the contact chamber (7) has a side wall opening (11) through which the undercut (6) of the inserted contact (2) is accessible from the outside.
