Abstract

This device severs a part of insulation material 2 from substantially straight, covered conductor assembly 1 without nicking or otherwise distorting wire 3 enclosed within conductor 1. Conductor 1 lies within the aligned openings of and is grasped by chucks 4 and 5, which are spaced apart from each other. Chuck 4 then is advanced toward chuck 5 along a path parallel to the axis of wire 3. The parts of insulation 2 grasped by chuck 4 and lying between chucks 4 and 5 slip over the surface of wire 3. The stiffness of wire 3 maintains the wire straight.

Mechanical Wire Stripper

This device severs a part of insulation material 2 from substantially straight, covered conductor assembly 1 without nicking or otherwise distorting wire 3 enclosed within conductor 1. Conductor 1 lies within the aligned openings of and is grasped by chucks 4 and 5, which are spaced apart from each other. Chuck 4 then is advanced toward chuck 5 along a path parallel to the axis of wire 3. The parts of insulation 2 grasped by chuck 4 and lying between chucks 4 and 5 slip over the surface of wire 3. The stiffness of wire 3 maintains the wire straight.

The movement of chuck 4 stretches the part of insulation 2 lying between the chucks into a disc-like bubble indicated as A. The continued advance of chuck 4 impales on cutting point 6 the bubble of insulation at a point of the bubble close to the undisturbed, outer surface of conductor 1. Point 6 is remote from the surface of wire 1 and is connected by arm 9 to annular ring 8, which is journaled to chuck 5 and which is substantially concentric with conductor 1. Rotation of ring 8 causes point 6 to slit insulation bubble A about conductor 1.

After the slitting operation is complete, chucks 4 and 5 are moved apart in order to draw the severed end of insulation 2 grasped by chuck 4 away from the remainder of conductor 1. The chucks are further manipulated to carry the severed end of insulation 2 clear of wire 3 and to release the severed insulation portion from chuck 4.
