Abstract

Abstract Apparatus for trimming the end of a wire and inserting the wire into a terminal in a multi-contact connector comprises a reciprocable ram and a supporting means for supporting the connector in spaced relationship to the ram. The ram cooperates with a stationary shearing member disposed beside the path of reciprocation of the ram so that upon movement of the ram towards the connector, the wire is moved past the shearing member, its end is trimmed, and the trimmed wire is inserted into the terminal in the connector.
