ABSTRACT:
A hand tool for verifying the proper installation of pins in the insulation body of a multi-pin connector, said tool including a tubular handle having received on the interior thereof a cylindrical casing. Formed around the periphery of the casing is an exteriorly directed groove communicating through a plurality of radially directed bores with an interior concentric cavity. A plurality of balls are received within the radial bores, each ball being further urged into the interior by an associated follower or bushing. Disposed within the groove around said bushings are two rubber O-rings dimensioned to urge the balls toward the interior cavity. A probe provided with a peripheral ball seat is received within the interior cavity of the casing to be thus retained by the balls in longitudinal translation. The probe then extends through a tubular guide to terminate on the free end thereof in a probe tip which can then be pressed against the male pin of a multi-pin connector.
