HAND TOOL FOR PRESSING WIRE CONNECTORS Abstract of the Disclosure A hand tool for pressing wire connectors to establish electrical connection between a plurality of insulated wires inserted into the connector includes an elongated body having a mouth at one end for receiv- ing a wire connector with wires inserted therein. A movable jaw is pivotally mounted on the body for move- ment about a first pivot laterally offset from a longi- tudinal axis of the body forming a movable wall of the mouth for compressing the connector to a precise geometric configuration. An operating handle is pivot- ally connected to the jaw for movement about a second pivot on the jaw and the handle has an opposite outer end portion movable toward and away from the tool body for moving the jaw between open and closed posi- tions. A thrust element is pivotally interconnected between a third pivot on the handle and a pivot point at the outer end of the tool body. The handle is pivoted relative to the jaw on an operating stroke moving the jaw from an open position toward a closed position with a rapidly increasing mechanical advan- tage for providing a maximum compressive force gener- ally aligned with the longitudinal axis of the tool and transversely across the inserted connector as the third pivot approaches the longitudinal axis of the tool body.
