Coaxial Cable Stripper

This cutting blade for a wire stripping hand tool enables insulation to be stripped from a wire without nicking or scratching the wire.

The basic tool, shown in U.S. Patent No. 2,313,793, comprises a normally closed pair of coacting jaws 1 and 2. These are pivoted about an axis 3 and are opened and closed by handles 4 and 5. Jaw 1 carries a pair of coacting and normally open clamping members 6 and 7 for gripping an insulated wire 8. Jaw 2 carries a pair of coacting and normally open wire stripping blades 9 and 10. Members 6 and 7 and blades 9 and 10 are urged to the closed position about wire 8 during the first portion of the travel of handles 4 and 5 as they are drawn together. Jaws 1 and 2 are pivoted to the open position during a subsequent portion of the travel of handles 4 and 5 which are being drawn together.

Each of the cutting blades is designed to have complementary grooved configuration which, when the blades are in the closed position, form a cylindrical cutting zone defined by an annular blade edge 11 disposed between cylindrical guide bores 13 and 14. The cross-sectional dimensions of bores 13 and 14 are sized so that when they seat on the insulation of wire 8 they dispose wire 8 in a position which prevents the blade edge 11 from contacting wire 8.

Such a coacting configuration of the blade grooves is obtained by forming the groove of blade 9 with a concave blade edge 11a. The latter is disposed between concave recesses 13a an...
