Abstract
Abstract An electrical cable loosening device, for loosening an electric cable having a conductor wire covered by an insulating material, has a clamping unit, a stop unit, and a pounding unit. The clamping unit clamps the electrical cable. The pounding unit pounds and bends the cable end portion against the stop unit. Thus, the insulating material separates from the conductor wire at the end portion to facilitate the stripping of the insulating material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A stripping method for stripping an electrical cable having a conductor wire wound around a core member and a coating member tightly mounted on said conductor wire, said method comprising the steps of: clamping said electrical cable at a clamping position which is adjacent an end portion of said electrical cable; pounding and bending said end portion to separate said coating member from said conductor wire; and stripping said electrical cable of said coating member at the pounded end portion.
Claim 2
Dependent Claim
80 words
A stripping method for stripping an electrical cable having a conductor wire wound around a core member and a coating member tightly mounted on said conductor wire, said method comprising the steps of: clamping said electrical cable at a clamping position which is adjacent an end portion of said electrical cable; pounding and bending said end portion to separate said coating member from said conductor wire; and stripping said electrical cable of said coating member at the pounded end portion.
Claim 3
Dependent Claim
126 words
An electrical cable loosening device in combination with an electrical cable and for loosening said electrical cable, said electrical cable having a conductor wire wound around a core member and a coating member tightly mounted on said conductor wire, said electrical cable loosening device comprising: a frame structure; a stop surface formed on said frame structure; a clamping means for clamping said electrical cable at a clamping position which is adjacent an end portion of said electrical cable; and a pounding means provided on said frame structure and in association with said stop surface, for repeatedly pounding and bending said end portion of said electrical cable including said coating member against said stop surface to attendantly loosen and separate said coating member form said conductor wire.
Claim 4
Dependent Claim
126 words
An electrical cable loosening device in combination with an electrical cable and for loosening said electrical cable, said electrical cable having a conductor wire wound around a core member and a coating member tightly mounted on said conductor wire, said electrical cable loosening device comprising: a frame structure; a stop surface formed on said frame structure; a clamping means for clamping said electrical cable at a clamping position which is adjacent an end portion of said electrical cable; and a pounding means provided on said frame structure and in association with said stop surface, for repeatedly pounding and bending said end portion of said electrical cable including said coating member against said stop surface to attendantly loosen and separate said coating member form said conductor wire.
