Embodiment Construction

[0019] Preferred embodiments of the present invention will be described.

[0020] In the conductive wire with a sealing function according to the present invention, the sealing part and the covering part may be formed of the same material.

[0021] According to such a structure, since a sealing part and a covering part are made of the same material, they are joined easily, and sealing performance is ensured effectively. In addition, since the rigidity of the conductive wire is increased at the portion where the sealing portion is formed, so-called waist folding (buckling of the conductive wire) can also be prevented from occurring. In addition, the sealing portion may be formed over the entire length of the covering portion in the covering portion.

[0022] According to such a structure, it is possible to further improve the sealing function inside the conductive wire.

[0023] Next, an embodiment of the conductive wire with a sealing function of the present invention will b...

Abstract

The invention provides a conductive wire with seal function and a manufacturing method thereof. A conductive wire includes a core formed of a plurality of conductive metal strands, a coating portion formed of an insulating material and configured to cover the core and seal portions arranged at intermediate positions in a coating portion and configured to hold clearances between the strands and between the core and the coating portion in a water-tight state. A sealant is supplied before the respective strands are twisted. By doing so, the sealant can be spread to a central part of the core and the clearances between the strands can be filled with the sealant.

Description

technical field [0001] The invention relates to a conductive wire with a sealing function and a manufacturing method thereof. Background technique [0002] Conventionally, ground terminals are often connected to electrical equipment for automobiles via wires, and some of such ground terminals are arranged in engine compartments and the like of automobiles. Since the engine room is a water-receiving area, when the wire core wire connected to the wire sleeve of the ground terminal receives water, the water easily penetrates into the wire coating layer through between the wire rods. When water is soaked in the covering layer of the electric wire in this way, there is a possibility that the soaking progresses due to the capillary phenomenon and reaches the electrical equipment. [0003] As an example of a method for avoiding the above-mentioned situation, the disclosure of the following Patent Document 1 is known. [0004] prior art literature [0005] patent documents [00...
