ABSTRACT:
A light weight, portable device for stripping a section of tough, resilient electrical insulation from a free end portion of a wire to expose the electrical conductor previously enveloped by the sheath section. The section of the sheath enveloping the end portion is severed from the balance of the sheath by radially compressing a thin longitudinal sheath section through substantially the entire periphery thereof to form the section into one that has an extremely thin wall. When the sheath section is so compressed, the device is moved longitudinally and parallel to the wire in a direction to tension the compressed wall section to the extent it breaks, and longitudinal movement of the device being continued to slide the severed sheath section from the end portion of the electrical conductor to expose the latter. Stops are provided on the device to prevent the latter coming into contact with the electrical conductor during the compression of the sheath section. Contact of portions of the device with the electrical conductor during such compression is undesirable, and could give rise to a nick or the like in the conductor that under stress may serve as a source of origin for cracks, fissures and the like to develop in the electrical conductor.
