A method of making a waterproof intermediate spliced portion of wires and waterproof inter-spliced unit of wires

摘要

A method of making a watertight intermediate spliced portion (10) of wires, comprising: (a) a step of supplying a water sealant (40) to an intermediate spliced portion (20) of wires; (b) a step of covering said waterproofing agent (40) supplied to said intermediate spliced portion (20) with a protective sheet (30); and (c) a step of hardening the waterproofing agent (40) while maintaining a state where the surface of the waterproofing agent (40) and the protective sheet (30) are in direct contact by deforming the protective sheet (30) following holding the deformation of the surface of the waterproofing agent (40) with the protective sheet (30) wrapped around the waterproofing agent (40) supplied to the intermediate spliced portion (20) and pulled out, overlapping outer portions, and the waterproofing means (40) between overlapping parts toward the intermediate spliced portion (20) by ironing the overlapping parts of the protective sheet (30) in a state sandwiching between a plate and a round bar member (62) is sandwiched between or between a pair of rod-like members (70) is pushed and / or pressed during the step (b), the water-sealing agent (40) being photocurable; the protective sheet (30) is capable of transmitting light for curing the waterproofing agent (40); and the water-sealing agent (40) is hardened by irradiating with light to harden the waterproofing agent (40) in the step (c).
