US 6,546,617 B1 · Method of peeling off coating of insulated conductive wires

Abstract

A method of peeling off a coating of an elliptical cross sectional insulated conductive wire has a groove forming process of forming a groove nearly perpendicular to a longitudinal direction of the insulated conductive wire at given positions within a peeling region thereof, a first peeling process of peeling off the coating by moving a pair of first cutting edges in a longitudinal direction of the insulated conductive wire and perpendicularly to a longer diameter direction of the cross section thereof toward the groove from opposite ends of the peeling region, and a second peeling process of peeling off the coating at the peeling region by moving a pair of second cutting edges in a direction perpendicular to the longitudinal direction and in parallel with the longer diameter direction of the cross section thereof. As a result, the coating all around the outer circumference of the insulated conductive wire at the peeling region may be completely peeled off.

Dependent claims

A method of peeling off a coating of an insulated conductive wire at a peeling region covering a predetermined length in a longitudinal direction thereof by cutting edge means, the insulated conductive wire being constituted by a conductor and the coating covering and being entirely and strongly connected with the conductor all around an outer circumference thereof, comprising steps of:

forming a groove by removing the coating and a part of the conductor at a predetermined position of the peeling region;
and
executing a first peeling process of peeling off the coating on a surface of the insulated conductive wire at the peeling region by making the cutting edge means cut into the conductor so as to penetrate through the coating at a leading end of the peeling region and moving the cutting edge means relatively to the insulated conductive wire in a longitudinal direction thereof toward the groove.

A method of peeling off a coating of a near square shaped cross sectional insulated conductive wire at a peeling region covering a predetermined length in a longitudinal direction thereof by grinding stone means, the insulated conductive wire being constituted by a conductor and the coating covering the conductor around an outer circumference thereof and having four round corner surfaces and four nearly flat side surfaces, comprising steps of:

peeling off simultaneously the coatings at the peeling region on any one corner surface of the four corner surfaces and on adjacent any two side surfaces of the four side surfaces between which the any one corner surface is put by making the any one corner surface and the adjacent any two side surfaces come in contact with any one of the grinding stone means whose grinding surface has a profile corresponding to shapes of the any one corner surface and the adjacent two any side surfaces and moving the insulated conductive wire relatively to the any one of the grinding stone means in a longitudinal direction thereof.
