The present invention has been made in view of the above points, and an object thereof is to provide a closed switchboard which prevents a part of a human body from inadvertently entering a bus room or a cable room.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention mounts a plurality of horizontal wiring circuit breakers in a vertical line on a mounting metal fitting at the rear side of the inside of the main body of the board, and installs the circuit breakers on the left and right sides of the circuit breaker. In a closed switchboard having a bus room and a cable room, and a protective plate provided between the control wiring room on the front side inside the board body and the bus room and the cable room, the mounting bracket is provided so as to be movable back and forth. Mounting auxiliary body, a first mounting means for mounting the auxiliary body whose front surface is substantially flush with the protective plate on the mounting bracket, and the circuit breaker on the front surface of the circuit breaker. A second mounting means for mounting the auxiliary body, the front surface of which is substantially flush with the protective plate, on the mounting bracket.

[0007]

[Action]

 In the closed switchboard of the present invention configured as described above, the mounting bracket is provided with the mounting auxiliary body so as to be movable back and forth, and when the wiring breaker is mounted on the mounting auxiliary body, the second mounting means causes the circuit breaker to operate. The front surface of the auxiliary body can be positioned substantially on the same plane as the protective plate, and when the circuit breaker is not mounted, the first mounting means can position the front surface of the auxiliary body substantially on the same surface as the protective plate, Electric shock can be prevented without accidentally entering arms or the like into the bus room or cable room.

【Example】

 One embodiment will be described with reference to FIGS. 1 to 3. In these figures, the same reference numerals as those in FIGS. 4 and 5 indicate the same or corresponding ones. Reference numeral 15 is a mounting bracket having a shorter depth than that of the conventional mounting bracket 2, 16 is a mounting auxiliary body having a U-shaped cutting plane, and the circuit breaker 3 for wiring is detachably mounted on the front plate 17. Reference numeral 18 is in sliding contact with the outer surfaces of both side plates 19 of the mounting bracket 15 and is provided on the mounting bracket 15 so as to be movable back and forth.

Reference numeral 20 denotes a mounting hole that is transparently provided in the front portion of both side plates 19 of the mounting bracket 15, 21 is a first hole that is transparently provided in the rear portion of the side plate 18 of the auxiliary body 16, and 22 is a side plate 18. The second hole is provided through the front portion, 23 is the third hole provided slightly behind the second hole 22, 24 is the large hole provided on both sides of the front plate 17, and 25 is the large hole. The mounting hole 20 and the first hole 21 constitute a first mounting means 26, and the mounting hole 20 and the second hole 22 constitute a second mounting means 27. Is configured.

In the case of a large-sized circuit breaker 3, as shown in FIG. 3A, the circuit breaker 3 is mounted through the large-sized hole 24 of the mounting auxiliary body 16, and the second hole 22 is attached to the mounting hole of the mounting bracket 15. 20, and the auxiliary body 16 is attached to the mounting bracket 15 with bolts and nuts, and the front surface of the circuit breaker 3 is positioned almost flush with the protective plate 10.

Next, in the case of the small circuit breaker 3, as shown in FIG. 3B, the circuit breaker 3 is mounted through the small hole 25, the third hole 23 is fitted into the mounting hole 20, and the auxiliary body 16 is attached. It is attached to the mounting bracket 15, and the front surface of the circuit breaker 3 is located substantially flush with the protective plate 10.

Further, when the circuit breaker 3 is not mounted, as shown in FIG. 1, the first hole 21 is fitted to the mounting hole 20 and the auxiliary body 16 is attached to the mounting metal fitting 15. The plate 17 is positioned almost flush with the protection plate 10. The first hole 21 and the second hole 22 are formed in the side plate 19 of the mounting member 15, and the mounting hole 20 is formed in the side plate 18 of the auxiliary body 16 to configure the first and second mounting means 26, 27. You may do it.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the closed switchboard of the present invention, when the mounting auxiliary member 16 is provided on the mounting member 15 so as to be movable back and forth, and the wiring auxiliary circuit breaker is mounted on the mounting auxiliary member 16, the front surface of the circuit breaker 3 is provided by the second mounting means 27. Can be positioned substantially on the same plane as the protective plate 10, and when the circuit breaker 3 is not mounted, the first mounting means 26 can position the front surface of the auxiliary body 16 on substantially the same surface as the protective plate 10. Therefore, the arm of the human body does not accidentally enter the bus room 4 or the cable room 6 and an electric shock can be prevented.
