Abstract

PROBLEM TO BE SOLVED: To make a distribution board be of a thin type by forming the central part of a cover to be a projecting curved surface so that it be recessed from a master switch and branch switches projecting most from a body. SOLUTION: A cover 4 has side walls 46 in the circumference and projecting holes 26 through which switch handles 16 project, in the upper side 34, and it is fitted to a body 1 and covers a master switch 2 and branch switches 3. The side wall 46 in the direction of connection of a connecting terminal part and the upper side 34 in this portion are made continuous through a curved part 27, while the upper side 34 is composed of a central part 28 covering upper surfaces 31 of the master switch 2 and the branch switches 3 and of side parts 33 stretching from the central part 28 to the curved parts 27, and the central part 28 is formed to be a projecting curved surface, while the side parts 33 are formed to be virtually flat surfaces. As the result, the side parts 33 being virtually flat surfaces can be made near to the body 1 and, since the upper side 34 and the side walls 46 are continuous through the curved parts 27, the whole of this board can be made to be of a thin type. Since the master switch 2 and the branch switches 3 are fitted in proximity to the body 1, besides, the thickness of the whole board can be lessened further.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board applied to general households and the like.

[0002]

2. Description of the Related Art A conventional distribution board of this type has a body to be mounted on a mounting surface of a wall, a main switch and a plurality of branch switches mounted to this body, and a projecting hole for passing these opening / closing handles. And a cover attached to the body to cover the main switch and the branch switch.

[0003]

However, this distribution board has a drawback in that it has a large thickness and appears to project largely from the mounting surface. Therefore, an object of the present invention is to provide a distribution board which is thin.

[0004]

According to a first aspect of the present invention, there is provided a distribution board having a body mounted on a mounting surface, an opening / closing handle projecting on an upper surface, connecting terminals at both ends, and a bottom surface mounted on the body. And a main switch, which has an opening / closing handle projecting on the upper surface, has connection terminals at both ends, and attaches the bottom surface to the body, wherein the connection direction of the connection terminal is the connection terminal of the main switch. A plurality of branch switches arranged side by side in the main switch so as to be in the same direction as the connection direction of the main switch, and a projecting hole for projecting the open / close handle on the upper surface of the branch switch and attached to the body. And a cover for covering the main branch switch and the branch switch, the cover being continuous with the side wall in the connecting direction of the connection terminal portion and the upper surface via a curved portion, and the upper surface being the main trunk. Switch and minutes A central portion for covering the upper surface of the switch,
It is characterized in that it is composed of side portions extending from the central portion to the curved portion, the central portion is formed into a convex curved surface, and the side portions are formed into a substantially flat surface.

According to the distribution board of the first aspect, since the central portion of the cover is formed in a convex curved surface so as to escape the main switch and the branch switch that are most protruded from the body, the side portions of the substantially flat surface approach the body. Moreover, since the upper surface and the side wall are continuous at the curved portion, it is possible to reduce the overall thickness. A distribution board according to a second aspect of the present invention is the distribution panel according to the first aspect, wherein the main switch and the branch switch are attached close to the body.

According to the distribution board of claim 2, in addition to the effect of claim 1, the overall thickness can be further reduced.
The distribution board according to claim 3 is the distribution board according to claim 2, wherein a wiring passage extending in a connection direction of the connection terminal portion is formed on at least one of both sides of an inner unit including the main switch and the branch switch of the body. It was done.

According to the distribution board of claim 3, in addition to the effect of claim 2, wiring becomes easy.

Further, a large number of wire knockout portions 11 are formed on the upper side wall 10 of the peripheral side wall 5.

As shown in FIGS. 2 and 3, the main switch 2 has an opening / closing handle 8 projecting from an upper surface 30, has connecting terminal portions 9 at both ends, and has a bottom surface attached to the body 1. In the embodiment, the main switch 2 is an earth leakage breaker, the connection terminal portion 9 is formed lower than the upper surface 30 and protrudes outward,
The upper connection terminal portion 9 in FIG. 3 is the input side, and the lower connection terminal portion 9 is the output side. The bottom plate 13 is attached to the bottom surface of the main switch 2 with screws 12, and the bottom plate 13 is connected to a frame 22 described below to be locked to the positioning / mounting portion 15 and fixed with the screws 14, whereby one side portion of the body 1 is attached. Installed on. 18 is a connection terminal portion 9 of which one end is an output side
And 47 is a cover plate of the connection terminal portion 9 on the output side.

The branch switch 3 has an opening / closing handle 16 projecting from the upper surface 31, has connection terminal portions 17 at both ends, and attaches the bottom surface to the body 1.
Are arranged side by side on the master switchgear 2 so that the connection direction thereof is the same as the connection direction of the connection terminal portion 9 of the master switchgear 2. In the embodiment, the branch switches 3 are vertically arranged in two horizontal rows and arranged in parallel with the master switch 2, and the connection terminal portion 1 facing between the two rows.
7 as the input side, and a pair of 200V branch bars 18 between the two rows
And a 100V branch bar 19 between them are provided, and each end is connected to the connection path 18 by a connection screw 21. Further, a pair of frames 22 are attached to the bottom surface of the branch switch 3 with screws 23, and the frames 22 are connected to the bottom plate 13 to connect the body 1
It is locked to the positioning / mounting portion 15 and is attached by the screw 14. The frame 22 raises the branch switch 3 to the bottom so that the main switch 2 and the top of the branch switch 3 are flush with each other. 40 is a cover plate.

Main switch 2 and a plurality of branch switches 3
Is attached in close proximity to the body 1 as described above, and a wiring passage extending in the connecting direction of the connection terminal portion 9 to one side of the inner unit formed by the main body switch 2 and the branch switch 3 of the body 1. Four
5 is formed. The cover 4 has a side wall 46 on the periphery thereof and has projecting holes 25 and 26 for projecting the opening / closing handles 8 and 16 formed on the upper surface 34 thereof.
