Abstract
Abstract A tool for fastening a wire-bearing terminal pin to terminal lug. A drive member is slidably mounted in a tube having a longitudinal opening in the tube wall at one end thereof. A terminal pin having a wire crimped thereto is pushed into the end of the tube until the tip of the terminal pin touches the tip of the drive member. As this occurs, the wire passes through the longitudinal opening and is deflected away from the tip of the terminal pin thus to clear the path of movement of the drive member, this being accomplished by a deflecting surface at the tip of the drive member. The end of the loaded tube is slipped over the companion terminal lug until the contact between the flat end of the tube and the mounting surface of the terminal lug orients the longitudinal axis of the tube along the longitudinal axis of the terminal lug. This allows the end of the drive member to pushingly engage the tip of the terminal pin while the contact between the terminal pin and the tube wall prevents the application of a lateral force to either the terminal pin or the terminal lug. The longitudinal movement of the drive member forces the terminal pin substantially longitudinally into intimate electrical contact with the terminal lug. As the tool is removed, the terminal pin passes through the end of the tube and the wire passes through the longitudinal opening in the wall thereof.
