Abstract
Abstract A connector terminal checking device includes a base, a conduction checking part rotatably supported by the base to check the conductive condition of a connector to be checked, an abutting part attached to the base to come into contact with a rear end of the connector mounted on the conduction checking part arranged in a conduction check position, a compression spring for urging the conduction checking part against a stand-by position and a solenoid for holding the conduction checking part in the conduction check position when checking the connector. In an initial state of the device, the solenoid is not energized, so that the conduction checking part is moved in the stand-by position by the compression spring. After the connector is inserted into the conduction checking part, it is pressed to the conduction check position by an operator. During checking, the solenoid is energized to maintain the conduction checking part in the conduction checking position. After checking, the solenoid is inactivated, so that the conduction checking part is raised from the base by the compression spring.

Claim 10
Independent Claim
195 words
A method of checking connector terminals with a connector terminal checking device having a base portion having a free end, a stay having a free end pivotably joined therewith at common ends thereof, a solenoid adapted to draw the free ends together, and a compression spring adapted to urge the free ends apart from a conduction check position to a stand-by position whereat the solenoid is not energized so that the stay is urged by the compression spring to increase the angle of the stay with respect to the base and the conduction checking part to which a connector is to be attached to and detached from, comprising the steps of: mounting the connector with terminals onto a conduction checking part supported by the stay; pivoting the conduction checking part from the stand-by position to the conduction check position against an urging force of the compression spring so that a rear end of the connector abuts an abutting part of the checking device by energizing the solenoid; checking the conduction of the connector terminals while holding the conduction checking part in the conduction check position; and releasing the solenoid to return to the initial state.
