Even if the internal pressure increases above the male electrode 20, the O-ring 16
Since there is no effect on the lower sealed space, the rubber stopper does not come off. Next, the operation of the present embodiment having the above configuration will be described. In the lower case 10, an O-ring 16 is attached to the upper end of the male screw portion 23 of the male electrode 20, inserted into the cylindrical body 12 protruding from the upper surface of the lower case 10, and penetrated through the through-hole 11. A crimp terminal 51 is crimped to the end of the electric wire 50, and is inserted from the side of the crimp terminal 51 into the cylindrical portion 17 on the side surface of the lower case 10. Lower case 1
The collar 24 is inserted through the cylindrical portion 15 on the back surface of No. 0 and inserted into the male screw portion 23, the crimp terminal 51 is inserted, and the nut 25 is screwed and tightened. Then
The male electrode 20 is fixed to the lower case 10 by sandwiching the periphery of the through hole 11 between the flange portion 22 and the collar 24, and the electric wire 50 having the crimp terminal 51 fixed to the tip is also connected.

The male screw 41 of the female electrode 40 is inserted into the screw holes 31 and screwed together. Thus, the female electrodes 40, 40 are fixed to the upper case 30 and are conducted through the fuse 60. After this,
When the upper case 30 is put on the upper surface of the lower case 10, the female electrode 40 is inserted into the cylindrical body 12 protruding from the upper surface of the lower case 10. Female electrode 40 is cylindrical 1
2, the conductive portion 21 at the tip of the male electrode 20 is inserted into the female electrode 40,
The female electrode 40 is inserted into the seal member 13 held on the step 12a on the opening side of the cylindrical body 12. at first,
The male electrode 20 is inserted without contacting the female electrode 40, but when penetrating the louver 42 held on the inner peripheral surface, the male electrode 20 is electrically connected to the female electrode 40 via the louver 42. I do. Since the contact is made via the louver 42, the insertion resistance is small. On the other hand, when the female electrode 40 penetrates through the seal member 13, the female electrode 40
The seal member 13 is compressed and held between the inner peripheral surface of the cylindrical member and the inner peripheral surface of the cylindrical member 12 to form a water-like space inside the cylindrical body 12. Thus, the conductive portion 21 of the male electrode 20 and the louver 42, which is the conductive portion of the female electrode 40, are held in a space that is nectar to water from above.

固定される。When the upper case 30 is further pushed in, the female electrode 40 is inserted into the cylindrical body 12, and the internal pressure in the sealed space increases. However, since the O-ring 16 is mounted between the through-hole 11 and the male screw portion 23 and is hermetically sealed, the rise in the internal pressure does not affect the area below the panel. Conversely, since no rubber stopper is attached to the lower part of the panel, water may enter, but the O-ring 16 prevents the water from entering upward. Therefore, the conductive portion 21 of the male electrode 20 and the louver 42, which is the conductive portion of the female electrode 40, are maintained in a humid manner even when water is immersed from below. When the upper case 30 is sufficiently pushed into the lower case 10, the lock arm 33 formed on the outer surface of the upper case 30 is engaged with the wedge-shaped projection 19 formed on the outer surface of the lower case 10, and
Fixed.

The number of openings can be reduced as compared with the case where all the openings are closed with rubber stoppers, and a sealing space is formed above when the upper case 30 is put on, so that the O-ring 16 seals even if the internal pressure increases. Also, even when the opening is closed with a rubber stopper, it does not come off.
