Description

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

Previously, for example, as in JP-A No. 48-39939,
There was a distribution board that had an inner cover that covered the internal wiring circuit and exposed the breaker handle, and was attached to the support pole of the lower box using mounting screws. However, there was a drawback that the inner cover could not be easily attached because the screw holes in the inner cover and the screw holes in the support pillar could not be easily aligned.

Therefore, the purpose of this invention is to provide a distribution board whose inner cover can be easily attached to a support pole.

An embodiment of this invention is shown in FIGS. 1 to 7. That is, 1 is a lower box, 2 is a door, 3 is its hinge, 4 is a handle, 5 is a main breaker, 6 is a branch breaker, and 7 is an 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 support column 8 is an iron rod with a U-shaped cross section, and an end plate 10 is formed at the tip, and a screw hole 11 is formed in the end plate 10. A tongue piece 14 extends from the plate 13. A cap-shaped buffer member 15 made of plastic or rubber is attached to the tip of the support post 8, and the threaded hole 1

is formed. On the other hand, the lower support column 9 is made of iron and has a U-shaped cross section, with a vertical plate 1 at the tip, as shown in Figures 4 and 5.
A hook 18 is formed extending from the tongue 7, a hook recess 19 is formed on its upper surface, a plastic hook cap (buffer member) 20 is attached to the tongue, and a hook recess 21 is fitted into the hook recess 19. is formed.

The inner lid 7 has a hole 22 that exposes the operating parts of the breakers 5 and 6, a hook hole 23 corresponding to the hook cap 20, and a screw hole 1 of the support column 8.
A screw through hole 24 is formed corresponding to 1. To install the inner lid 7, first hook the hook hole 23 into the hook recess 21 of the cap 20, and then insert the mounting screw 2 into the screw through hole 24.
5 into the guide hole 16, and screw hole 1.
Screw in 1. 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 inner cover 7 comes into contact with the buffer member 15 and does not directly contact the iron support pillar 8, so the paint on the inner cover 7 does not peel off, rust does not occur, and the buffer member 15 does not come into contact with the inner cover 7 directly. Since the guide hole 16 for guiding the mounting screw 25 into the screw hole 11 is provided, screw tightening becomes easy and the inner cover 7 can be easily attached and detached.

As described above, the distribution board of this invention has a receiving post erected inside, an end plate having a screw hole at the tip of the receiving post, and a tongue protruding at a higher position than the end plate. a lower box provided at the tip of the support pillar; an inner lid placed on the tip end surface of the tongue piece and having a screw hole that matches the screw hole; and a lower box that is screwed into the screw hole through the screw hole. a mounting screw for fixing the inner cover to the support post, and a guide hole that is interposed between the inner cover and the distal end surface of the tongue and guides the mounting screw, and a guide hole for guiding the mounting screw. Since it is provided with a buffer member formed between the hole and the hole, it has the following effects.

In other words, by forming the tongue piece which is located at a higher position than the end plate and on which the inner cover rests via the buffer member, a screw tightening space is formed between the end plate and the inner cover, and it is possible to tighten the end plate by drawing it to the inner cover. This allows the inner lid to be firmly fixed. Furthermore, since the guide hole of the buffer member is arranged in this space, the guide hole allows the mounting screw to be guided to the screw hole that is difficult to see when the inner cover is attached, making it easier to attach the inner cover. Moreover, since the inner cover does not come into contact with the support pillar due to the buffer member, peeling of the paint on the inner cover can be prevented.
