The handle opening 21 is different from the bank 31 of the circuit breaker 30 on the center line in the width direction, and the center line A of the handle opening 21 extends from the center line B of the width of the cover 20 to the dimension C. Only the position shifted downward is formed. That is, the dimension in the width direction of the handle opening 21 from the edge of the board cover 20 is different from the dimension in the width direction from the edge of the circuit breaker 30 of the opening / closing operation handle 32 . For this reason, the upper plane part (wide plane part) 22 from the handle opening 21 has a relatively wider surface than the lower plane part (narrow plane part) 23.

A large shallow square recess 24 and a plurality of small shallow recesses 25 are formed on the surfaces of the wide planar portion 22 and the narrow planar portion 23, respectively, for attaching a name plate. Two pairs of ridges 26 are formed on the back surface of the cover 20 so as to face each other at a pitch of the same dimension W2 as the width dimension of the panel opening 41 of the panel of the switchboard.

For this reason, the name plate 27 has the same size as the recess 24 and is disposed under the protrusions 28 formed on the left and right ends of the recess 24. Therefore, the name plate 27 can be easily mounted and replaced, and does not easily fall off. ing.

When the cover 20 is attached to the front panel of the panel, the cover 20 is arranged so that the bank 31 of the circuit breaker 30 fits into the handle opening 21, and the left and right ridges 26 are connected to the panel opening 41 of the front panel. Engage with the left and right inner edges. In this way, if the plurality of covers 20 are attached corresponding to the plurality of circuit breakers 30, for example, the wide flat portion 22b of the panel cover 20b corresponding to the circuit breaker 30b is on the upper side with respect to the opening / closing operation handle of the circuit breaker 30b. And a ridge projecting by a dimension C in the direction of the circuit breaker 30a adjacent to the upper side. Therefore, this scissors cover a part of the surface of the circuit breaker 30a and also covers the contact portion between the circuit breaker 30b and the circuit breaker 30a. Further, the lower surface of the circuit breaker 30b opening / closing operation handle has a narrow flat surface portion 23b of the panel cover 20b and a flange of the wide flat surface portion 22c of the panel cover 20c corresponding to the circuit breaker 30c adjacent to the lower side. Covered by.

Referring to FIG. 5, the cover 20 is formed with a wrap edge 29 that protrudes from the back surface of the upper side of the cover 20 so as to overlap the wrap edge 29 of one cover 20b. By disposing the lower edge of the cover 20a, no gap is generated between the cover 20a and the cover 20b.
Further, since the wide flat surface portion 22a of the upper end cover 20a and the narrow flat surface portion 23d of the lower end cover 20d cover the upper edge portion 41a and the lower edge portion 41b of the panel opening portion 41, the entire panel opening portion 41 has a plurality of covers. 20 with no gaps.

With reference to FIG.6 and FIG.7, the other board | substrate which attached the cover 20 of the Example by this invention is demonstrated. This panel can be attached with a cover 20, but is provided with a circuit breaker 2 having a width W3 wider than the circuit breaker 30, and a gap cover 50 having a width commensurate with the difference in width (W3-W1) is provided. It is a thing.

The board shown in FIG. 6 has a plurality of circuit breakers 2 composed of the circuit breaker body 4 and the base member 3 described in the prior art, and is arranged so that the base members 3 are in contact with each other.
In order to facilitate understanding of the description of this board, in the following description, the width of the above-mentioned circuit breaker body 4 is set to W1 = 90 mm which is the same as the width of the above-mentioned circuit breaker 30, and the width of the base member 3, that is, The overall width of the circuit breaker 2 is W3 = 120 mm. Further, when it is necessary to distinguish between the circuit breakers 2 and the gap cover 50, the description will be made by adding symbols such as “a” and “b” to the symbols as illustrated.

In the case of FIG. 6, the upper edge of the relatively lower cover 20f is located between the upper circuit breaker body 4a and the lower circuit breaker body 4b, and the upper edge and the upper side of the lower cover 20f. A portion between the lower edge of the cover 20e is a gap that is not covered by any of the covers 20e and 20f. By attaching two gap covers 50a and 50b having a width of W4 = (W3-W1) / 2 to such a gap, the entire opening of the panel can be manufactured without manufacturing a cover having a width of W3. The cover 20 with the width W1 can be used to cover the gap without any gap.

Referring to FIG. 7, the gap cover 50 is a thermoplastic molded insulator, and a plurality of pieces divided by a groove for each width are continuously manufactured, and can be divided and used by the required number. . Similar to the cover 20, the gap cover 50 is provided with a pair of flanges 51 at a pitch W2 on the back surface, so that it can be attached to the opening 41 of the panel. In FIG. 6, the lower edge of the lower gap cover 50b is attached so as to overlap the wrap edge 29 of the lower cover 20f.
In FIG. 6, two gap covers 50 having a width of W4 are used, but one cover having a width of (W3-W1) may be used.

With reference to FIG. 8, still another board to which the cover 20 of the embodiment according to the present invention is attached will be described. This board is mounted so that the above-mentioned circuit breaker 30 having a width W1 = 90 mm and the circuit breaker 2 having a width W3 = 120 mm are alternately combined to be in contact with each other, and the gap between the cover 20 and a piece having a width W4 = 15 mm. A cover 50 is attached.
The board of FIG. 8 has a cover 20g, a cover 20h and a cover 20k attached to the circuit breaker 2c, the circuit breaker 30d and the circuit breaker 2d, respectively, and further between the lower edge of the cover 20g and the upper edge of the cover 20h and below the cover 20h. One piece of the gap cover 50c and the gap cover 50d are attached between the edge and the upper edge of the cover 20k so that the upper edge and the lower edge of each cover are in contact with each other. This allows, without width to produce the cover of the W3, Ru can range covers without gaps an entire opening of the panel by using the cover 20 of W1.

In the panel of FIG. 8, only a total of three circuit breakers, one circuit breaker 30 and two circuit breakers 2, are attached. However, from the technique shown in FIGS. It can be easily understood that a board in which the circuit breaker 30 and the circuit breaker 2 are freely combined and attached in contact with each other can be configured.
