  A lid member 6 including a lid body 4 and a base member 5 is attached to the front surface of the rectangular parallelepiped case 1. The base member 5 is formed in a rectangular shape that covers the entire surface of the case 1 with a synthetic resin. And the opening part 8 for exposing the open / close lever 7 of the main circuit breaker 2 and the branch circuit breaker 3 is provided in the center part, and it fixes to the case 1 with the screw 9 at the both sides of the opening part 8. .

  Further, around the base member 5, a peripheral edge portion 10 that is bent in a direction along the outer surface of the case 1 is formed. As shown in FIG. 4, when the case 1 is accommodated in the mounting portion 11 provided on the wall surface or the like, the peripheral edge portion 10 comes into contact with the mounting surface 12 around the mounting portion 11.

  The lid 4 is formed of a synthetic resin as a rectangular member having an area that can cover the entire surface of the base member 5. A hinge portion 13 is formed on the upper edge portion of the lid 4 and the base member 5, and the lid 4 can be flipped upward with the hinge portion 13 as a rotation fulcrum.

  A cover portion 14 extending along the peripheral edge portion 10 of the base member 5 is formed around the entire periphery of the lid body 4 except for the hinge portion 13 and the finger hook portion 15 described later. As shown in FIG. 4, when the lid 4 is closed, the covering portion 14 of the lid 4 comes into close contact with the peripheral edge 10 of the base member 5 except for the upper edge of the base member 5. Yes.

  As shown in FIGS. 3 and 5, a finger hook 15 is formed at the center of the lower edge of the lid 4. This finger hook portion 15 is formed with a locking piece 16 formed by slightly denting the covering portion 14 inward, and the locking piece 16, so that the base end of the locking piece 16 is connected to the front surface of the lid 4. And a finger-hanging piece 17 extending downward.

  A concave portion 18 is formed in the peripheral edge portion 10 of the base member 5 at a position facing the finger hook portion 15. As shown in FIG. 5, when the lid body 4 is closed, the lid body 4 can be rotated by inserting a fingertip into the recess 18 and pulling the finger-hook piece 17.

  A locking projection 19 is formed on the back surface of the locking piece 16 (the upper surface when the lid 4 is closed), and the peripheral edge 10 of the base member 5 is locked at a position facing the locking projection 19. A hole 20 is formed. And in the state which closed the cover body 4, the latching convex part 19 elastically engages with the latching hole 20, and the cover body 4 is hold | maintained in the closed state.

  As shown in FIG. 3, an accommodation recess 21 is formed on the front surface of the base member 5 above and below the opening 8 so as to be recessed from the peripheral portion of the base member 5 through a step. Even when the lid 4 is closed, a space that does not hinder the rotation of the open / close lever 7 of the main circuit breaker 2 and the branch circuit breaker 3 is secured.

  As shown in FIG. 7, a convex portion 22 is formed on the rear surface of the base member 5 so as to protrude toward the rear surface side in order to form the accommodating concave portion 21. As shown in FIG. 6, the height of the convex portion 22 from the front surface of the base member 5 is formed lower than the height of the peripheral edge portion 10 of the base member 5, and the height difference h is secured. In other words, the thickness of the peripheral edge portion 10 of the base member 5 is thicker than the thickness of the base member 5 other than the peripheral edge portion 10.

Next, the operation of the residential distribution board configured as described above will be described.
As shown in FIG. 1, the base member 5 is substantially covered with the lid body 4 when the lid body 4 is closed. Accordingly, when the case 1 is attached so as to be immersed inside the attachment portion 11 such as a wall surface, only the lid 4 is exposed in the room, so that the aesthetics of the room is not deteriorated.

The peripheral edge 10 of the base member 5 is attached in close contact with the attachment surface 12 around the attachment 11, and the cover 14 of the lid 4 is held in close contact with the peripheral edge 10 of the base member 5. .
Therefore, the indoor where the distribution board is attached and the inside of the case 1 of the distribution board are almost sealed by the base member 5 and the lid 4, so a case of small insects such as ants, dust, dust, etc. Intrusion into 1 is prevented.

  When the lid 4 is opened to operate the opening / closing lever 7, if the finger is placed on the finger hooking piece 17 at the center of the lower edge of the lid 4 and pulled to the front, the lid 4 is rotated with the hinge portion 13 as a rotation fulcrum. By moving it, it is possible to open the lid 4.

  When the distribution board is transported, the lid member 6 is packed in a state where the lid body 4 and the base member 5 are laminated. At this time, since the convex portion 22 at the center of the back surface side of the base member 5 is lower than the peripheral portion 10 by the height difference h, the weight of the lid member 6 laminated at the time of packing does not apply only to the convex portion 22. . Therefore, damage of the convex part 22 at the time of packing and conveyance is prevented.

In the residential distribution board as described above, the following effects can be obtained.
(1) Since the central convex portion 22 of the base member 5 is formed lower than the peripheral edge portion 10 with a height difference h, even if the lid member 6 is laminated and packed at the time of packaging, The weight is received by the peripheral edge portion 10 and the covering portion 14. Accordingly, since the weight of the laminated lid member 6 does not act on the convex portion 22, damage to the convex portion 22 can be prevented in advance.
(2) Since the peripheral portion 10 and the covering portion 14 are provided on the base member 5 and the lid body 4, the mechanical strength of the base member 5 and the lid body 4 can be improved.

The above embodiment may be modified as follows.
The height difference h between the convex portion 22 and the peripheral edge portion 10 may be zero.
The technical idea that can be grasped from the above embodiment will be described below.
