Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the rainproof joint box of the present invention. The body 1 made of an insulating material is formed in a substantially L-shape, and includes a back plate 2 and a bottom plate 3. At the end of the back plate 2 of the body 1, a plurality of mounting holes 4 for screw insertion for mounting on the outer wall surface are formed.

An electric wire insertion hole 5 is formed between the mounting holes 4, and a rectangular electric wire insertion hole 6 is formed at the center. At one end of the central portion of the back plate 2 is formed a terminal block mounting portion 8 on which a terminal block 7 for 100 V / 200 V to which a power supply line from the outside is connected. At the other end of the central portion of the back plate 2, a terminal block mounting portion 10 for arranging a terminal block 9 for weak electricity such as a telephone line is formed.

The terminal block 7 is attached to the terminal block mounting portion 8 with a tapping screw 11, and a rib 12 is formed around the terminal block 7 to prevent water from entering the terminal block 7. In addition, the terminal block 9 is also attached to the terminal block mounting portion 1 with a tapping screw 13.
A rib 14 is provided around the terminal block 9 to prevent water from entering the terminal block 9. Body 1 backboard 2
Side walls 15 are integrally provided with the bottom plate 3 on the upper side and both sides of the base plate 3 to prevent water from entering. A flange 16 is formed on both sides of the back plate 2, and a groove 17 is formed on the outer surface of the side wall 15 by a rib 18 formed in a vertical direction. A plurality of notches 19 are formed in the middle of the rib 18.

The bottom plate 3 of the body 1 is formed with three knockout portions 20 for inserting a conduit tube erected from the ground, and the tip of a driver is inserted into the center of the circular knockout portion 20. A slit 21 is formed. In the center of the body 1, an insulating separator 22 for separating the terminal block 7 for the power supply line and the terminal block 9 for the weak electric current is arranged, and the end of the separator 22 is inserted and supported. A groove 23 to be formed is formed inside the side wall 15. A rubber packing 24 having a rectangular frame shape is mounted on the back surface of the body 1, and water enters the back surface of the body 1 with the packing 24.

A cover 25 mounted on the front surface of the body 1 and made of an insulating material has an opening on the back surface and the bottom surface.
A large transparent window 41 is formed on the front surface of 5 so that the internal connection state can be easily checked. The side wall 1 of the body 1 is provided inside the side plate 26 of the cover 25.
A plurality of fixing ribs 27 are formed to be inserted and locked in the grooves 17 through the cutouts 19 formed in the groove 5.

A hole 28 is formed in the lower portion of the front surface of the cover 25, and a mounting screw 30 having a spring 29 inserted therein is inserted from the front surface. . Next, a case where the cover 25 is mounted on the body 1 will be described. The cover 25 is slightly shifted upward at the front of the body 1 installed on the wall surface, and the positions of the fixing rib 27 of the cover 25 and the notch 19 of the body 1 are aligned. Then, when the cover 25 is pushed toward the body 1, the fixing rib 27 is inserted through the notch 19,
By sliding the cover 25 downward and inserting and locking the fixing rib 27 into the groove 17 of the body 1, the rib 1 of the body 1 is locked.
8 and the fixing rib 27 of the cover 25 are at the same position, and the cover 25 is fixed to the body 1. Then, the cover 25 is fixed to the body 1 by pushing the mounting screw 30 against the spring force of the spring 29 and screwing it into the screw hole of the body 1.

When the cover 25 is to be removed from the body 1, the mounting screw 30 is removed, and then the cover 25 is slid slightly upward so that the fixing rib 27 and the notch 19 are aligned. When pulled, the cover 25 can be easily removed from the body 1. Here, the amount by which the cover 25 is slid is only the amount by which the fixing rib 27 is fitted to the notch 19, and therefore, even if there is an obstacle 32 immediately above the body 1, the amount of slide of the cover 25 is small. The cover 25 can be easily attached and detached.

Next, a case where the cover 25 is temporarily fixed to the body 1 will be described. As shown in FIG. 1, ribs 36 are formed at upper ends on both sides of the body 1.
A rib 38 having a concave portion 37 engaging with 6 is formed at a lower portion of the inner surface of the cover 25. The surface of the projection 39 above the rib 38 is curved so that the rib 36 can easily get over the rib 36.

Now, from the state where the cover 25 is completely covered with the body 1, the cover 25 is slid upward while the fixing rib 27 of the cover 25 is slid into the groove 17 of the body 1. When the cover 25 reaches the upper end of the body 1, the protrusion 39 of the rib 38 of the cover 25 rides over the rib 36 of the body 1, and the concave portion 37 of the rib 38 and the rib 36 engage with each other.

The cover 25 moves the body 1 by this uneven engagement.
Is temporarily fixed to the body 1 with its front surface exposed.
