Tester for testing correct assembly of terminals in connector housings

摘要

A terminal assembly tester comprises a contact probe module having electrical contact probes. The contact probes have a contact surface biasable against tips of electrical terminal mounted in cavities of a connector housing. The connector housing comprises integrally moulded resilient locking lances that are separated from housings walls by a slot. Extensions of the contact probes are insertable into the housing slots when contacting the terminal tips. If a terminal is not fully inserted into a cavity, the resilient locking lances are biased into the slot and prevent insertion of the contact probe tip thereinto thereby ensuring that the contact probe does not electrically contact the terminal. The latter thus ensures that even almost completely inserted terminals will not be electrically contacted and thus provides for a reliable testing mechanism.
