ABSTRACT:
A waterproof method for a wire end joint includes expanding a heat shrinkable tube radially outwardly. The method then includes inserting the wire end joint and a melted thermosetting waterproofing agent through an opening at an end of the waterproof protection tube. A solidification starting temperature of the waterproofing agent is set higher than a shrinkage starting temperature of the heat shrinkable tube. The method then applies heating so that the heat shrinkable tube shrinks to the original diameter and so that the waterproofing agent is not solidified. The heating is continued to the solidification starting temperature after the heat shrinkable tube is shrunk to a set inner diameter, thereby causing the thermosetting waterproofing agent to be solidified.
