Abstract
An object is to enable a fluid synthetic resin to easily spread into the gaps between a plurality of insulated wires when a waterproof portion covering a spliced portion of a wire group is obtained by curing the fluid synthetic resin, thereby ensuring a sufficient waterproofing performance. A pair of first clamping portions sandwich a first covering portion of the spliced portion of the wire group between a parallel pair of first supporting surfaces. A swing mechanism reciprocally displaces one of the pair of first clamping portions sandwiching the first covering portion relative to the other and parallel to the first supporting surfaces.
Claims6
A waterproofing method of a wire spliced portion, comprising:
- first clamping including sandwiching, between a parallel pair of first supporting surfaces of a mutually opposed pair of first clamping portions, a first covering portion of a wire group including a plurality of insulated wires and having a spliced portion where conductors of the insulated wires are joined, the first covering portion being located at a position spaced from an end portion of an insulating covering that faces the spliced portion;
- swinging including reciprocally displacing one of the pair of first clamping portions sandwiching the first covering portion relative to the other and parallel to the first supporting surfaces;
- parallelism maintaining including maintaining at least the end portion of the insulating covering of the wire group in a parallel condition at the end of the swinging;
- and
- waterproof portion forming including covering, with a fluid waterproofing material, a waterproof region of the wire group whose parallel condition is maintained by the parallelism maintaining, and further curing the waterproofing material, the waterproof region extending from the spliced portion to the end portion of the insulating covering.
A wire group alignment apparatus that aligns a portion of an insulating covering of a wire group including a plurality of insulated wires and having a spliced portion where conductors of the insulated wires are joined, into a condition in which the plurality of the insulated wires are arranged in a line, comprising:
- a pair of first clamping portions that have a parallel pair of first supporting surfaces and that sandwich, between the pair of first supporting surfaces, a first covering portion of the wire group that is located at a position spaced from an end portion of the insulating covering that faces the spliced portion;
- and
- a swing mechanism that reciprocally displaces one of the pair of first clamping portions sandwiching the first covering portion relative to the other and parallel to the first supporting surfaces.
