ABSTRACT:
A portable hand-held power-operated cable stripper is disclosed. A pressure arm is disposed in and pivotally joined to a handle, so as to have a portion extending therefrom that is gripped during the use thereof. The pressure arm has a forward clamping portion that moves in a first direction and in a second opposite direction. A cable shield stripping means including a motor and a rotary blade driven by the motor is disposed in the handle. The cutting blade is aligned with the forward clamping portion of the pressure arm, such that when the pressure arm is pivoted in the first direction towards the handle, the shielded cable is clamped by the forward clamping portion of the pressure arm and pushed into contact with the cutting blade which longitudinally cuts and strips the shield from the cable. When the forward clamping portion of the pressure arm is pivoted in the second direction, the cable is released. A switch is provided for controlling the flow of electric power from an electric power source to the motor. This switch is activated and deactivated by the movement of the pressure arm that results from the gripping of the handle, so that when the pressure arm is gripped, the switch is automatically switched "on", and further so that when the pressure arm is released, the switch is automatically switched "off". In this manner, a user may both hold the cable cutter and activate the cutting blade thereof with only one hand.
