ABSTRACT:
A connector housing (22) before insertion of a terminal lug thereinto is set in an inspection chamber (7) on a connector inspection device (A), so that a movable pin (9) of an inspection pin (8) is located inside a front end portion of the terminal-accommodating chamber in the connector housing. With the terminal lug thereafter inserted into the accommodating chamber, the movable pin is moved back against a spring (11) so that, when the terminal lug has been fully inserted, the movable pin comes into contact with a stationary pin to energize an inspection electric circuit (18). Thus, the full insertion of the terminal lug (C) can be known. Hold on the terminal lug is then released to allow the terminal lug to retract by a distance corresponding to a clearance (D) present between an edge of a locking portion (28) of the terminal lug and a locking projection (24a) of a resilient locking piece (24), so that the movable pin is now separated from the stationary pin to shut off the inspection electric circuit. Owing to the above, concurrently with the insertion and locking of terminal lugs in terminal-accommodating chambers in a connector housing, the terminal lugs can be individually inspected for their insertion condition.
