Abstract
Abstract A method of protecting a conductive connecting part of a flat cable and a protecting structure of the cable are provided. The method includes a step of connecting conductors of the flat cable to conductors of relay wires at the conductive connecting part, a step of arranging a protective member at the exterior of an insulating cover part of the flat cable, a step of interposing the protective member between opposing molding dies and accommodating the conductive connecting part of the flat cable in a cavity defined by the molding dies in a leak-tight manner, and a step of supplying insulating material in the cavity for an insert molding. The protecting structure includes the conductive connecting part, the protective member and the insulating member for enclosing the conductive connecting part together with a leading end of the protective member. The insulating member is formed by insert molding. Since the cover part is not held by the mold directly, but is held through the intermediary of the protective member in forming the conductive connecting part, it is possible to moderate a force applied on the conductors by the aid of the protective member without increasing a thickness of the cover part of the flat cable, so that the breaking of the conductors can be prevented with certainty.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A method of protecting a conductive connecting part of a flat cable, at which said flat cable is electrically connected to an object, said flat cable comprising a conductor and an insulating cover part for enveloping a major portion of said conductor, said object including another conductor to be connected to said conductor of said flat cable, said method comprising the steps of: connecting a portion of said conductor, not enveloped by said insulating cover part of said flat cable to said conductor of said object at said conductive connecting part; arranging a protective member at an exterior of said insulating cover part in a direction of thickness of said insulating cover part; interposing said protective member between opposing molding dies in the direction of thickness, and accommodating said conductive connecting part of said flat cable in a leak-tight manner in a cavity defined by said molding dies; supplying insulating material in said cavity, thereby insert-molding an insulating member for enclosing said conductive connecting part; and wherein each of said molding dies is provided, on both sides of said cavity, with a recess for holding said protective member and a groove for holding said object, respectively.
Claim 2
