Wire Stripper

This tool scores a miniature coaxial cable for stripping the same to prepare it for a termination.

Annular housing 10 is mounted to be axially reciprocable as indicated at 12 on an inner, spider member. The latter has first and second cam parts 14 and 16 interconnected by pins 18. Housing 10 and cam parts 14 and 16 are bored axially at 20, 22, and 23 to receive the cable to be stripped. Housing 10 mounts three scoring knives 24, 26, and 28 for coaction with shoulder portions 30 of parts 14 and 16.

The plan drawing shows knives 24 and 26 in their relaxed, planar position. Each knife has a central aperture 32 and 34 and a system of radial slits 36 and 38 which permit conical deflection of the knife so as to open its central aperture. Slits 36 of knife 24 have holes 40 to pass pins 18.

In operation, housing 10 is retracted to the position shown so that the knives are pulled down onto shoulders 30. This deforms them into the conical shape as shown in section. Central apertures 32 and 34 are thus opened so as to admit a piece of coaxial cable when it is fed into position in the tool through the openings 20, 22, and 23.

When the housing is reciprocated to an extended position so that the blades relax to their planar positions, the apertures of the blades assume their contracted condition. Aperture 32 of blade 24 is dimensioned to score the outer sheath of the cable. The apertures of the knives 26 and 28 are proportioned to score the insulation and the cen...
