In the embodiment, the substrate 11
The three conductive bars 2a to 2 are mounted on the fixed base 13 fixed to the
c is supported. The first conductive bar 2a and the second conductive bar 2b are positioned on both sides of the partition plate 14 of the fixed base 13 by the partition plate 14 and the positioning protrusions 15 standing on the fixed base 13, and the first and second conductive bars 2a and 2b are positioned. A pair of leg pieces 16 standing up from the side of the partition plate 14 side of the second conductive bar 2a, 2b and extending to the branch breaker 3 adjacent to each conductive bar and the branch breaker 3 located on the opposite side to the partition plate 14. , 17 are stepped up and down and extend. The third conductive bar 2c is attached to the upper ends of the columns 19 standing on both ends of the partition plate 14, and the upper leg 17
Is located at a distance substantially equal to the above step.

The plurality of branch breakers 3 are arranged side by side in the extending direction of the conductive bar 2 and connected to the conductive bar 2. That is, the branch breaker 3 is a plug-in type having a receiving blade 22 that is inserted and connected to the conductive bar 2. Further, a locking projection 23 is provided on the surface of the branch breaker 3 on the insertion tip side of the conductive bar 2, and an elastic hooking member 24 for locking the locking projection 23 is provided on the upper surface of the third conductive bar 2c, and The insulating cover 4 is arranged so as to be in contact with the upper surface of the elastic hooking member 24. Accordingly, when the insulating cover 4 described later is provided, the elastic hooking member 24 is prevented from being deformed, and the locking projection 23 can be prevented from coming off from the elastic hooking member 24.

In the embodiment, a pair of locking projections 23 on the upper surface of the branch breaker 3 are provided. The elastic hooking member 24 is formed of, for example, a synthetic resin molded product, has a plurality of protrusions (not shown) on the lower surface of the main body 26, and is press-fitted into a plurality of holes 46 formed on the upper surface of the third conductive bar 2c. And then the third
It is attached to the conductive bar 3c. This elastic hook member 24
1 and 4, as shown in FIG. 1 and FIG.
Has T-shaped hooks 27 with the number of branch breakers on both sides of
An intermediate portion of the leg portion 27a of the hook portion 27 is rotatably connected to the main body 26 and is biased in the hook direction by resin elasticity.
Both shoulders of the T-shaped hook 27 are elastically locked to the locking projection 23 to prevent the branch breaker 3 from coming off. On the other hand, fixed base 13
Is provided with a hook-shaped projection 28 corresponding to the rear end of the branch breaker 3, and a hook-shaped recess 29 for catching the projection 28 is provided on the side surface of the branch breaker 3. When removing the branch breaker 3, the leg portion 27a of the hook portion 27 of the elastic hook member 24 is removed.
The shoulder portion of the hook portion 27 is released from the locking projection 23 by pushing the end portion of the main body side of the branch breaker 3 to the conductive bar 2a.
By pulling it away from 2c, the projection 28 is simultaneously removed from the recess 29, so that the branch breaker 3 can be removed.

The insulating cover 4 covers the conductive bars 2a to 2c from above and also has a load name display section 32 for displaying the load name of each branch breaker and a handle exposing section 33 for exposing the handle 3a of the branch breaker 3. Have. The insulating cover 4 is connected to the load name display portion 32 and is provided with an enclosure portion 7 that surrounds the outermost portions of the plurality of branch breakers 3. On both sides of the back surface of the insulating cover 4, the central portions of the inverted U-shaped attachment pieces 35 are attached, and elastic claws 36 are provided at both ends thereof. On the other hand, the receiving portions 38 on which the elastic claws 36 are hooked are formed at both ends of the fixed base 13 by, for example, penetrating cylindrical portions. The insulating cover 4 is fixed by the mounting piece 35 to the fixed base 13
When fixed to the elastic hooking member 24, the back surface of the elastic hooking member 24 abuts against the upper surface of the elastic hooking member 24 as shown in FIG.
From the locking projection 23.

The lid 6 has a through hole 40 through which the load name display portion 32 of the insulating cover 4 faces, and is attached to the open surface of the box 5. In the embodiment, the lid attachment members 62 are provided upright on both ends of the attachment plate 10 of the box body 1, and the lid 6 is attached to the upper end of the lid attachment member 62 by the attachment tool 43. The through hole 40 has a size equal to or larger than the four peripheral end faces of the surrounding portion 7, and has a large vertical size, for example. Then, the insulating cover 4 is stepped so as to fall in the direction of the box body 5 at both end edges in the direction in which the through hole on the outer periphery of the surrounding portion 7 has a large dimension, and the tongue piece with which the edge portion of the through hole 40 engages. 8 are provided. In this case, the edge portion of the through hole 40 and the surrounding portion 7 and the load name display portion 32 are arranged in a step with the edge portion of the through hole 40 engaged with each other. As a result, the surface of the lid 6 does not become uneven, and the appearance is good.

According to this embodiment, even if the cover 6 is removed from the box 5, the load name display portion 32 is still on the insulating cover 4 inside the box 5, so the cover 6 is removed and each branch breaker 3 is removed. When connecting each load to, it is possible to easily determine which load corresponds to the breaker, which improves workability. In addition, the peripheral edge of the through hole 40 of the box body 5 has a plurality of branch blurs.
Even if it does not fit perfectly on the outermost side of the mosquito, it can be hidden by the tongue piece 8, and the work of producing the through hole of the lid 6 becomes easy.

[0021]

According to the distribution board according to the first aspect of the present invention, even if the cover is removed from the box, the load name display portion is located on the insulating cover inside the box, and therefore the cover is removed and each branch breaker is attached to each branch breaker. When connecting the load, it is possible to easily determine which load corresponds to the breaker, which improves workability. Further, even if the peripheral edge of the through hole of the box body is not perfectly fitted to the outermost of the plurality of branch breakers, it can be hidden by the tongue piece, and the work of forming the through hole of the lid becomes easy.

According to the distribution board of claim 2, claim 1
In addition to the same effect as above, the surface of the lid does not become uneven, and it looks good.

According to the distribution board of claim 3, claim 1
Alternatively, in addition to the same effect as the second aspect, by disposing the insulating cover, it is possible to prevent the elastic hooking member from being deformed and prevent the locking projection from coming off from the elastic hooking member.
