Abstract
A cable stripping tool for the preparation of high voltage cable for termination or splicing by simultaneously removing the semiconducting sheathing from a section of cable and insulation and sheathing from the end section of the cable to expose the conducting core. The tool has a tubular body with a central bore which receives the cable. The body has an adjustable scoring blade disposed in a longitudinal slot which scores the sheathing at a predetermined distance. An insulation cutting blade is radially disposed in the central bore which cuts the sheathing and insulation upon rotation of the body. In one embodiment, a shaft is coupled to the tubular body to provide rotation of the body about the cable by a drill motor.
Claims19
An apparatus for stripping insulation from a cable, said apparatus comprising:
- (a) an elongate tubular body having a cylindrical bore with an axial opening at one end of said body, said body having a longitudinal raceway;
- (b) a scoring blade assembly slidably disposed in said longitudinal raceway;
- (c) a shank, said shank coupled with the elongate body along a central axis of rotation;
- and
- (d) an insulation cutting blade mounted to said body, said blade radially disposed within the cylindrical bore of said elongate body.
A cable stripping tool, comprising:
- (a) an elongate tubular body having proximal and distal ends and a central axis, said body having and an opening at the proximal end communicating with a first cylindrical bore and a contiguous second cylindrical bore centered about said central axis;
- said body having a longitudinal slot and race, said slot extending through said body to the first cylindrical bore;
- said body having a radial discharge port;
- (b) a shaft coupled with the distal end of the elongate tubular body;
- (c) a scoring blade assembly slidably coupled to said race, said assembly having a scoring blade disposed within said slot and said first cylindrical bore;
- (d) an insulation cutting blade disposed in said radial discharge port, said blade extending in to said first cylindrical bore;
- and
- (e) a bearing and bearing cap disposed in said second cylindrical bore perpendicular to said central axis.
A device for preparing an end of an insulated cable comprising:
- (a) a rotatable tubular body having an axis of rotation and a central bore, said bore centered in said axis of rotation;
- (b) means for scoring the exterior sheathing of a cable radially disposed in said bore;
- (c) means for cutting sheathing and insulation from a cable:
- (d) means for imparting rotation to said tubular body around said axis of rotation;
- and
- (e) a bearing and a bearing cap positioned at a distal end of said central bore.
