Abstract
An insulation stripper is described which is especially useful for shielded wire, the stripper including a first pair of jaws with blades extending substantially perpendicular to the axis of the wire, and a second pair of jaws with blades extending substantially parallel to the axis of the wire. The first pair of jaws is pressed against the wire so the blades thereof cut into the insulation, and the device is turned to form circumferential cuts in the insulation. Then the second pair of jaws is pressed against the wire so the blades thereof cut into the insulation, and the wire is moved through the device to form longitudinal cuts that permit easy removal of the insulation. Each of the blades is located within the concave face of a V-block, to center the blades on the wire and to limit the depth of blade penetration.
Claims3
A wire stripper comprising:
- a body forming a wire-receiving hole extending along a predetermined axis;
- a first pair of jaws moveably mounted on said body to move toward and away from said axis, each of said first jaws having a blade with an edge that extends substantially perpendicular to said axis, said jaws positioned directly opposite one another so their blades can form part of the same circumferential cut in the wire;
- and
- a second pair of jaws moveably mounted on said body to move toward and away from said axis, at least one of said second jaws having a blade with an edge that extends substantially parallel to said axis, whereby a person can clamp the first jaws and pivot the body by 90.degree. in opposite directions to form an approximately 360.degree. circumferential cut in the insulation and then clamp the second jaws to cut the insulation longitudinally as the wire moves out of said hole.
