ついには火災の原因となるものである。 Conventionally, in electrical appliances that are directly attached to a mounting surface such as a wall and wired internally, for example, a lighting fixture as shown in FIG.
A space 13 for accommodating the device is provided, and after the mounting bracket 3 is attached with screws 4 such as wood screws, the connection portion 7 is accommodated in the space 13 and the instrument main body 8 is attached. 2 is a plate-like packing. However, if the wiring is defective or the taping insulation is defective, it may lead to an electrical accident. To further explain this based on FIG. 7, this FIG. 7 shows, for convenience,
As the mounting surface 1, there is a wall surface (left half) on which a metal plate 16 is decorated on the surface of a base 15, and a metal lath 18 is applied to the base 15 through waterproof paper 17, and a wall material 19 such as cement or mortar is applied to the surface. This is also shown with the painted wall surface (right half), but there are poor connections,
In other words, the connection part 7 between the power supply line 5 and the internal wiring 6 of the appliance contacts the mounting bracket 3, and electricity is transmitted to the mounting bracket 3 and the screw 4.
If it is transmitted to a conductive member such as the metal plate 16 or metal lath 18 through the metal plate 16 or the metal lath 18, it may lead to an electrical accident. In other words, since electricity is constantly being transmitted to the conductive member on the mounting surface 1 side, it plays the role of a heater.
Eventually, this will cause a fire.

The figure shows a waterproof lighting fixture used in bathrooms, etc. as an example of an electrical appliance.As shown in Fig. It is composed of a metal fitting 3 and an instrument main body 8 attached to the fitting 3. A lamp 21 waterproofly covered with a globe 20 is provided on the appliance main body 8. As shown in FIG. 3, the interior of the device main body 8 is a space 13 for connecting the cord, and the connection portion 7 between the power supply line 5 and the internal wiring 6 of the device is accommodated in this space 13. Here, the mounting surface 1 in FIG. 3 is shown with separate left and right configurations for convenience, similar to the conventional example shown in FIG. 7. As shown on the left in FIG. 4, the insulating bushing 10 has an oblong screw insertion hole 23 in the center of a disk-shaped flat part 22, and an annular hanging rib 24 hanging from the periphery of the screw insertion hole 23. With the configured configuration,
As shown on the right side of the same figure, two types are used: one in which two screw insertion holes 23 are arranged in the flat part 22 and a hanging rib 24 is provided vertically in each screw insertion hole 23. An annular rising rib is provided on the flat part 22 of each insulating bushing 10 surrounding each screw insertion hole 23, and this is used as the insulating protruding rib 11. 25 is a nail. Mount the mounting bracket 3 at the mounting pitch l or m shown in Fig. 4 above.
A screw insertion hole 9 is provided that is large enough to fit the hanging rib 24 of each type of insulating bushing 10, and a claw hooking hole 26 into which each claw 25 is inserted and hooked is provided. The insulating bushing 10 is attached by fitting the hanging rib 24 and simultaneously inserting and hooking each claw 25 into the claw hooking hole 26. Further, draining pieces 3a are bent and vertically provided on the outer peripheral edge of the mounting bracket 3 and the inner peripheral edge of the cord insertion hole 3b, respectively. To install this mounting bracket 3, screw 4 with insulating bushing 10 attached.
From the top, insert the screw insertion hole 23 of the insulating bushing 10.
This is done by inserting the insulating bushing 10 through the hanging rib 24 and into the screw insertion hole 9 of the mounting bracket 3, and then screwing this into the mounting surface 1. With the mounting bracket 3 installed in this way,
The head 12 of the screw 4 is now sunk into the insulating protruding rib 11. The instrument main body 8 is fastened and fixed to the mounting piece 28 of the mounting bracket 3 with screws 27, and by this fixation, the instrument main body 8 is mounted with the connection part 7 accommodated in the space 13. With the device main body 8 installed in this way, even if the connection part 7 directly touches the mounting bracket 3, the insulating bushing 10 insulates the space between the screw 4 and the mounting bracket 3, and the leakage current from the connection part 7 is transferred to the screw 4. I have nothing to tell you. Furthermore, even if the connection part 7 tries to touch the screw 4 directly, this will not happen because the screw 4 is sunk in the insulating bushing 10, and current leakage directly transmitted from the connection part 7 to the screw 4 can be prevented. In addition, each draining piece 3a strongly presses the plate-shaped packing 2 portion against the wall surface coated with the metal plate 16 or wall material 19 such as cement or mortar,
Water adhering to the wall surface is not transmitted between the plate packing 2 and the wall surface to the mounting screw 4 due to capillary action. Therefore, water from the wall surface does not pass through the screw 4 and infiltrate into the device, and it is possible to suppress electrical leakage accidents caused by water.

に絶縁突出リブ１１を設けるものにしてもよい。 In addition to the above structure, the structure of preventing the connection part 7 from coming into direct contact with the screw 4 is such that, as shown in FIG. 6, an insulating bushing 10 is provided integrally with the plate-like packing 2, and an insulating protruding rib 11 is provided on the auxiliary insulating rib 11', which closely opposes the screw 4. may be provided.

事故を一層確実に防ぐことができるものである。 As described above, the present invention is an electric appliance in which the wiring part is housed in the space above the mounting bracket, and the screw is inserted into the screw insertion hole of the mounting bracket with an insulating bushing interposed therebetween, and this is screwed into the mounting surface. Since the mounting bracket is fixed, an insulating bushing is interposed between the mounting bracket and the screw, increasing the creepage distance and providing good insulation between the two, which prevents poor insulation at the wiring connection. However, the leakage current is not transmitted from the screw to the conductive member within the mounting surface, and accidents due to poor wiring can be reliably prevented.
In addition, water cutters are provided vertically on the outer periphery of the mounting bracket and on the periphery of the cord insertion hole, and each water cutter is pressed against the plate-shaped packing. Unlike the method of bringing the entire surface into contact with the packing, the present invention allows the draining piece to be strongly pressed against the plate-shaped packing, and this pressed plate-shaped packing part is strongly pressed against the mounting surface and adheres to the mounting surface. This effectively prevents water from flowing between the plate packing and the mounting surface and reaching the mounting screws due to capillary action, and prevents water from entering the appliance through the screws. Therefore, even if a leakage current flows through the mounting fitting due to poor taping of the connection portion, it is possible to prevent the leakage current from transmitting through the water to the screw and leaking to the outside. Furthermore, since the head of the screw is surrounded by an annular insulating protruding rib, moisture that accidentally enters the device will reach the screw head unless it gets over the insulating rib that protrudes beyond the surface of the insulating bushing. I can't do it,
Compared to the method of simply forming a recess and sinking the head of the screw into the recess, electric leakage accidents due to water can be suppressed. Furthermore, an annular insulating protruding rib that surrounds the screw head is made to protrude from the insulating bushing so as to isolate the connection between the screw head and the wiring part, so that the wiring part comes into contact with the screw head and the wiring is connected. It can prevent the insulation of the part from being damaged and leakage from the wiring part to the screw, and the protruding insulating rib can increase the creepage insulation distance between the screw and the wiring part, which can prevent faulty wiring from occurring. This makes it possible to prevent accidents even more reliably.
