Abstract: A wire clamp including a housing having a guide slot for receiving a wire, a first clamp arm rotatably mounted in the housing and having a first wire clamping surface, a second clamp arm rotatably mounted in the housing and having a second wire clamping surface, a bias means for applying a tension force between the first and second clamp arms, and an actuator cylinder for applying a pushing force against the first clamp arm. The second clamp arm, when receiving pressure from a wire inserted in the guide slot, rotates against the tension force toward a clamping position and thereby clamps such wire between the first and second wire clamping surfaces by the tension force. Activation of the actuator cylinder applies a pushing force against the first clamp arm to urge the first clamp arm to rotate against the tension force toward an open position so that an increased tension force simultaneously acting on the second clamp urges the second clamp to rotate toward an ejection position, thereby ejecting the wire.
