Description

[Detailed explanation of the idea] This idea concerns a distribution board.

Conventionally, regarding the installation of an inner cover that covers the internal wiring circuit and exposes the breaker handle, for example, as disclosed in Japanese Patent Application Laid-open No. 55-129477, a hook hole in the inner cover is hooked onto a protrusion on the lower box, and then a hook is attached to the protrusion. It has been considered to screw a stopper having a hooking hole to the inner lid.

However, there was a drawback that it was troublesome to attach and remove the inner cover, and the inner cover was prone to wobbling.

Therefore, the purpose of this invention is to provide a distribution board in which the inner cover can be easily attached and removed and the inner cover is less likely to rattle.

An embodiment of this invention is shown in FIGS. 1 to 7. That is, 1 is the lower box, 2 is the door, 3 is its hinge, 4 is the handle, 5 is the main breaker, 6 is the branch breaker, and 7 is the inner lid. Inside the lower box 1, the breakers 5, 6 and their wiring parts (not shown) are arranged, and a pair of upper support columns 8 and lower support columns 9 are installed in the opening direction. First, as shown in FIGS. 6 and 7, the upper support column 8 is an iron rod with a U-shaped cross section, and has an end plate 10 formed at its tip, a screw hole 11 formed in the end plate 10, and upper and lower plates 12 and A tongue piece 14 extends from the lower plate 13. A cap-shaped first buffer member 15 made of plastic or rubber is attached to the tip of the upper support column 8, and a tapered guide hole 16 is formed in correspondence with the screw hole 11. On the other hand, the lower support column 9 is made of iron and has a U-shaped cross section as shown in FIGS.
9 is formed, and a second cap-shaped (buffer member) 20 made of plastic is attached to this to form a hook recess 21 that fits into the hook recess 19.

The inner lid 7 has a hole 22 for exposing the operating parts of the breakers 5 and 6, a hook hole 23 corresponding to the hook cap 20, and a screw through hole corresponding to the screw hole 11 of the upper support column 8. 24 is formed. To install the inner lid 7, first hook the hooking hole 23 into the hooking recess 21 of the second buffer member 20, and then insert the screw 25, which is an example of a thumbscrew, into the hole 24 and the guide hole 16.
guide it and screw it into the screw hole 11. In this way, it can be installed so as not to come into contact with the internal wiring circuit. 26 is a circuit explicit label.

With this configuration, the second buffer member 20
This prevents the steel lower support column 9 from directly colliding with the inner cover 7, so there is no peeling of the paint, and the occurrence of rust can be prevented. through screw hole 1
1, the inner cover 7 can be easily attached and detached, and the structure of the inner cover 7 can be made simple by simply drilling a hole. Moreover, when the screws 25 are removed, the inner cover 7 can be easily removed. Since it can be held without twisting, it can be attached and detached safely. Furthermore, since the approximately V-shaped hooking recess 21 whose rear surface is approximately vertical and whose front surface is inclined is surrounded by the second buffer member 20, the inner lid 7 is initially fitted in the inner lid 7 and is tilted in the direction of the front inclination. In this state, when the weight of the inner lid 7 is applied and the inner lid 7 is rotated, the inner lid 7
Since the edge of the inner cover 7 bites into it, it is possible to prevent the inner cover 7 from wobbling, and since the inner cover 7 comes into contact with the substantially vertical rear surface, it is possible to hold the inner cover more securely.

As described above, the distribution board of this invention has an inner lid with a screw hole formed in the upper part and a hook hole formed in the lower part;
The lower supporting column is approximately V-shaped with the rear surface being approximately vertical and the front surface being inclined, and has a hook recess formed upwardly at the front end to be hooked into the hook hole, and has a screw hole aligned with the screw hole on the front end surface. a first buffer member interposed at a contact portion between the inner lid and the front end surface of the upper support pillar;
Since the second buffer member surrounding the hooking recess is provided, the following effects can be obtained. In other words, since the lower part of the inner lid is hooked into the hooking recess and the upper part is fixed with screws, the inner lid is easier to attach and detach than before, and the first buffer member and the second buffer member prevent the inner cover from being painted. It can prevent the occurrence of rust due to peeling. Moreover, since the approximately V-shaped hooking recess with the rear surface approximately vertical and the front surface inclined is surrounded by the second buffer member, initially when the inner lid is inserted, the inner lid is tilted in the direction of the front inclination, but in this state, the inner lid is When the lid is rotated under the weight of the lid, the edge of the inner lid bites into the second buffer member, which prevents the inner lid from wobbling, and also allows the inner lid to come into contact with the substantially vertical rear surface for more secure retention. It becomes possible.
