るという大なる利点を有する。<Effects of the Invention> As is already clear from the above description, the present invention has the following advantages:
In insulators used with internal wire connection terminals,
The covering tube of the metal terminal for maintaining insulation is formed of an insulating synthetic resin material, and one end of the wire insertion side is made to cover the covering part of the wire,
The covering portion is formed using a heat-shrinkable resin material,
In addition, a heat-melting resin layer is formed on the inner surface,
Furthermore, when the connecting parts of the metal connection terminal are in a connected position, the extended cylindrical parts that cover the connected parts are designed to overlap and fit each other, and at least one of them has a watertight structure that closes the gap between the two extended cylindrical parts. Since the ring is attached, after the male and female connection terminals are inserted and connected, the outer part of the tube is heated and shrunk, and at the same time, the hot-melt resin layer is melted and adhered to the wire sheathing, and the molten resin is applied. By acting as an adhesive and a sealant, it is possible to maintain sufficient watertightness of the clamping part of the electric wire to the connection terminal, and at the same time, the terminal clamping part and the end of the wire sheathing can be kept sufficiently watertight. It is possible to avoid local concentration of vibrations etc. at the base end of the bare electric wire between the
In addition, since the gap created between the extended cylindrical parts of the two covering tubes can be reliably closed in a watertight state by the watertight ring, it can be used in a state where the risk of electrical leakage is extremely low even in a humid atmosphere. At the same time, it has the great advantage of preventing intensive deterioration and damage at the base end of the bare wire due to external vibrations, tensile forces, etc., and ensuring a wire connection condition that can withstand many years of use.
