Description

[Detailed Description of the Invention] The present invention relates to an engagement method and shape of an inner lid of a distribution board having a single-opening upper lid with a built-in breaker inside.

Conventionally, the inner cover of this type of distribution board was generally engaged by screwing it to a support fitting protruding from the bottom of the lower box, but this method was difficult to connect the built-in breaker, measure insulation resistance, etc. When removing the inner cover from the distribution board, a tool such as a screwdriver is required, and the mounting screws are lost after the inner cover is removed.Also, the screw heads are exposed on the surface of the inner cover, making it less aesthetically pleasing. No etc.
It was getting a bad reputation.

The invention of the present invention was made in view of the above-mentioned points in order to provide an inner lid device that can be easily removed and attached without the need for tools and has a good appearance.

One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a lower box, 2 a single-opening top lid, and 3 an inner lid that covers a built-in breaker.

Figure 2 4 shows support fittings that stand upright from the bottom of the lower box at appropriate intervals above and below the lower box 1, and have their heads bent in an inverted L shape, and are attached directly to the bottom of the lower box or to the internal switch. The field with the mounting plate is screwed or spotted onto it.

3 is the above-mentioned upper support metal fitting 4 in two places on the upper side.
It has a hooking end 6 that is hooked to the inverted L-shaped head 5 from above, and has two fitting holes 7 on the lower side into which the engaging element 8 is fitted. The inner lid is provided with a convex knob 9 for lifting the inner lid, and the fitting hole 7 is shaped like a long rectangular window as shown in FIG. A small protrusion 11 is provided at the center back of the guide 10.

The engaging member 8 is composed of a finger hook head 12 and an L-shaped engaging foot 14 that is engaged with the inverted L-shaped head 5 of the above-mentioned support fitting 4. The thinned part 1 is provided in the part where the thinned part 15 is provided to give elasticity.
6, the bottom surface 13 of the finger hook head 12 and the L-shaped engagement foot 14
A sliding groove 17 is provided in parallel to this, and it is a resin molded product.

The engaging element 8 has L-shaped engaging legs 14 as shown in FIG.
The thin wall portion 16 of the vertical portion of is press-fitted in such a way that it is pushed into the space of the thinned portion 15, but after fitting, the sliding groove 17 narrows the sliding guide 10 of the fitting hole 7. This prevents the engaging element 8 from coming off from the fitting hole 7.

Furthermore, the engaging element 8 fitted into the fitting hole 7 is positioned at a position where the L-shaped engaging foot 14 engages with the inverted L-shaped head 5 of the lower support fitting 4, as shown in FIG. Fitting hole 7 on the side or in the position where it does not engage, the OPEN side in the figure.
The small protrusion 11 prevents movement, resulting in a stable state. However, when manually sliding the engager from the LOCK side to the OPEN side, or vice versa, the thin part 16 of the engager 8 moves into the space of the thinned part 15. Inner lid 3 pushed away by
It moves between the small protrusions 11 of the fitting hole 7.

As shown in FIG. 7, the inner lid 3 with the engaging element 8 fitted thereto as described above is hooked from above with the hooking end 6 onto the inverted L-shaped head 5 of the upper support fitting 4 that stands upright from the lower box 1. LOCK the engager 8, slide the engager 8 to the OPEN side of the fitting hole 7, cover it from the front, and then LOCK the engager 8.
Slide it to the side to complete the installation as shown in Figure 8.

On the other hand, when removing the inner cover 3, hold the engager 8 with your fingertips.
By sliding it from the LOCK side to the OPEN side, the engagement element 8 and the lower support metal fitting are disengaged, and can be easily removed by performing the reverse operation of the above-mentioned installation.

Furthermore, when installing or removing the inner lid,
Since the convex knob 9 can be held with fingers, the operation is very easy.

As described above, according to the embodiment of the present invention, there is no need to install screws for the inner cover, the screw head is not on the surface of the inner cover, so the appearance is good, and the cost is low because no parts other than the engager are required. . Attaching the engager to the inner cover is very easy because it is a press-fit type, and the operability when attaching and removing the inner cover to the distribution board is easier than using screws because no tools are required. It has the effect of becoming much better.
