Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a waterproof wiring device, such as an outlet or a switch, which is used by being attached to the rear side of the outdoors where there is a risk of rain water.

(Background Art) Conventionally, as shown in Fig. 1, this type of wiring device has a functional block d consisting of a container body a, a lid body, and a surface plate C, a blade receiving spring e, a door body f, a return spring g, and a functional block d. Contains parts such as terminal structure, and this function is professional.

However, it is necessary to position and hold the functional block d on the rainproof plate i by some means until it is fixed with the driving studs. This made assembly work difficult.

(Object of the invention) This invention has been made focusing on the above circumstances,
The purpose is to provide a waterproof wiring device that can position and hold the functional blocks simply by storing them in the rainproof plate, thereby preventing parts from coming apart and making assembly work easier.

(Disclosure of the Invention) The present invention will be described below with reference to FIGS. 2 to 5 in which it is applied to an electrical outlet as an embodiment. Reference numeral 1 designates a rainproof plate, which has an opening window 2 for connection operations on its lower surface, and a bulge 3 that is open for wiring on its back surface. Insertion holes 7, 8.9 for the operation button 4, test button 5, energization indicator lamp 6, etc. are formed on the front surface, and waterproof ribs 10 are formed around these holes.
The operating section 11 is formed by surrounding the operating section 11. 12 is a ground terminal, and 1 is a cord holder. 14 F'i is a rising piece, and one side is formed as an open end 15 at the lower edge 2a of the opening window 2, making it easy to bend. A 16fi functional block is made up of a combination of a container body 17, a lid body 18, and a surface plate 19 that loosely fits into the opening window 2, and a blade support spring and a load device connected to this blade support spring. An opening/closing mechanism (not shown) that detects electrical leakage and turns off the power is housed, and an operation button 4 and a test button 5 are located at positions corresponding to the insertion holes 7, 8.9 of the lid m. A power indicator lamp 6 is also provided. The display board 19 is provided with an inclined surface to which the upright piece 14 is deflected outward when the function block 16 is rotated in the direction F with one point of the function block 16 as the fulcrum A, and the function block 16 is attached to the bulge 3.
A hook protrusion is formed with a locking surface 21 that locks on the protruding upper piece 14 housed in the holder. Further, the dimension S from the fulcrum A of the bulging portion 3 to the upright piece 14 is smaller than the dimension R from the fulcrum A of the functional block 16 to the tip of the hook protrusion ρ. The cover is a rubber packing, and the rainproof plate 1
This prevents rainwater from entering through the gap between the rainproof plate 1 and the construction side when the rainproof plate 1 is attached to the construction material. 24 is a mounting frame. Reference numeral 25 denotes a hinge mechanism, which has a cylindrical shape above the operating portion 11 of the rainproof plate 1. An operation button 4 which is an opening door body, is formed into a box shape so as to close the operation part 11, and protrudes in the open state (off).
, the test button 5 and the energization indicator pump 6 are made transparent so that the states can be visually confirmed. Here, the term "transparent" includes colors that have translucency. In the door body part, a frame-shaped opaque part row is formed around the outer periphery of the transparent part n by multilayer molding or by combining different parts. This opaque part arrangement is formed at a position corresponding to the waterproof lip 1o and the hinge mechanism 5, and completely covers them. Reference numeral 25 denotes a hinge mechanism for attaching the door body passageway so that it can be opened and closed, and is supported by a shaft. 31 is a spring for stopping the doorway in an arbitrary open position or completely closing it;
(4) It is in contact with 3. Further, the other end 26b is formed with a notch, and since it can be opened and closed freely, rainwater accumulated inside the operation part 11, which cannot be prevented, is drained away. 33 is a transparent collar that makes it easy to insert the plug and also improves the waterproof performance of the plug blade insertion hole.

(Effects of the Invention) As explained above, this invention has an opening window 2 for operation on the bottom surface.
The rainproof plate 1 has a rear surface formed with a bulge 3 that is open for wiring, and a functional block that loosely fits into the opening window and is housed in the bulge 3. 2, and the surface plate 19 has an inclined surface I that bends the rising piece 14 outward when the functional block part is rotated about a point A as a fulcrum A, and the functional block Since the hooking protrusion η is formed with a locking surface 21 that locks the stand-up piece 16 housed in the bulge 3, the stand-up piece can be assembled simply by storing the functional block 6 in the rainproof plate 1. 14
By being able to position and hold the functional block (1) by engaging the hooking protrusion n, a waterproof wiring device is obtained which prevents the parts inside the functional block from becoming loose and makes assembly work easier.
