ることを目的とする。However, since the waterproof connector is a special connector, the parts cost is high and the waterproof connector is expensive.
There is a problem that the power supply side electric wire needs to be bundled with the product, which increases the overall cost. More specifically, the waterproof connector has both male and female sides,
These waterproof connectors must be connected to electric wires at the time of shipment from the factory in order to maintain waterproofness. Therefore, in addition to connecting the waterproof connector to the heater side,
The wires must also be connected to the waterproof connector on the power side. Therefore, wires for indoor wiring, which are not usually included in the product, are included in the product, which increases the cost. Then, an object of the present invention is to solve such a problem and to provide an inexpensive and safe electric wire connection part.

The connection portion between the device-side electric wire and the power-supply-side electric wire is housed in the space, and the space is sealed by closing the space with a rubber plug having a through hole through which the electric wire passes. As a result, a highly waterproof wire connection portion can be obtained without using a waterproof connector. In addition, since it has a simple structure, it can be manufactured at low cost.

In FIG. 1, an outlet box 1 is embedded in a wall surface W of a bathroom, and a waterproof case 2 is attached to a surface side thereof. The connector box 3 is inserted from the front side of the waterproof case 2 toward the outlet box 1 and buried in the wall surface W. Then, the mirror 4 is attached to the front surface side of the connector box 3. Mirror 4
This is an electric device that adheres a heater 5 for anti-fogging to the back surface and turns the heater 5 on and off by a switch (not shown) to prevent the mirror 4 from fogging. A heater-side electric wire 6 protrudes from the heater 5, and its tip is connected to a power-supply-side electric wire (indoor wiring) 8 on the outlet box 1 side. The mirror 4 is fixed together with the waterproof case 2 by a mirror stopper 7 screwed to the wall surface W. Among these, the following two parts should be waterproofed from water drops and moisture in the bathroom. 1. 1. Heater 5 attached to the back of mirror 4 Connection between heater side wire 6 and power source side wire 8

触することがないので、安全性が高い。[0008] The connector box 3 has a flange 3 around it.
It is a substantially hollow cylindrical body having a, and is fixed to the wall surface W with screws. Flange 3a of connector box 3 is waterproof case 2
The waterproof packing 11 is squashed by pressing the periphery of the center hole 2a against the wall surface with screws so that the outlet box 1 is kept waterproof. The connection portion between the power supply side electric wire 8 and the heater side electric wire 6 is housed in the connector box 3 in which waterproofness is ensured. Inside the connector box 3, three cylindrical spaces 12a, 12b, and 12c each having an opening at one end are formed, and each of these spaces serves as a storage space for a positive-side electric wire connection portion, a negative-side electric wire connection portion, and a ground plug connection portion. . Therefore, since the electric wires of different poles do not contact with each other, the safety is high.

a, 12b and 12c are covered with a rubber stopper 14. Rubber stopper 1
4 has two through holes 15 for passing the electric wires 6 and 8. After passing the heater-side electric wire 6 and the power-supply-side electric wire 8 through these through holes 15, respectively, the ends of both electric wires are connected with the connector 16. Connect. Therefore, this rubber stopper 14 allows the cylindrical space 12
a, 12b, and 12c, the cylindrical space 12 is closed.
The interiors of a, 12b, and 12c are hermetically sealed, and the waterproofness of the inside of the space is maintained, and the waterproofness of the wire connection portion housed therein is ensured.
