Requires a waterproof plug (rubber plug) 6 and an inner plate 4 for holding the terminal. Therefore, not only the number of parts is increased and the manufacturing cost is increased, but also much labor is required for assembling. In particular, since the epoxy resin requires a long time to be heated and cured, workability is poor. Further, the epoxy resin solution has a problem such as rash when touched.
Further, when the epoxy resin solution is injected into the housing 5, it may flow out to the electrical connection portion of the connection terminal 3 to impair the conductivity, or the injection amount may be insufficient.

When the rear end of the terminal including 5 is covered with the cover 16,
The gel-like UV curable resin 18 filled in the inside and the housing 13 enters into the gap between the fixed portion 15 of the connection terminal 12 and the partition wall 13e and the cover 16 to liquid-tightly seal the gap. As a result, the oil in the transmission case is not only transmitted on the outer surface of the electric wiring 11, but even if the oil penetrates the electric wiring 11 and tries to enter the connection terminal 12 side, the oil is prevented from entering. Further, since the ultraviolet curable resin 18 also enters the gap between the connection terminal insertion hole penetrating the vertical wall 13d and the connection terminal 12, oil is surely prevented from entering the fitting portion 13a. To be done.

It is possible to reduce the number of parts by eliminating the need for a rubber plug or the like to be fitted to the wire 13. In addition, the ultraviolet curable resin 18
Eliminates the inconvenience of requiring an injection work at the assembly site like an epoxy resin or taking a long time to heat and cure the resin, so that workability can be greatly improved.
Further, the ultraviolet curable resin 18 does not adhere to the hand and cause a rash unlike the epoxy resin. Further, unlike the epoxy resin, the ultraviolet curable resin 18 does not flow out to the tip portion of the connection terminal 12 and hinder the electrical conduction with the mating terminal.

The assembly can be completed in a short time without spending a long time for heating and curing the epoxy resin. Moreover, since the fixed portion of the connection terminal can be sealed liquid-tight by closing the cover, the assembly is extremely easy. Further, since the sealant is attached to the cover when the cover is open, the sealant can be directly visually inspected, and the sealant will not run short. Therefore, according to the present invention, it is possible to provide a connector that can seal a connection terminal in a liquid-tight manner without using an epoxy resin and that has a small number of parts and is easy to assemble.
