Switchboard

Abstract

A switchboard, wherein the main piece (31) of the mounting plate (30) has an extended piece (36) extending to the front side with an inverted L-shaped cross-section, and an extending piece (36) extending from the upper edge of the main piece (31) A plurality of inverted L-shaped hook claws (37) can be inserted into hook holes formed on the input-side end surface of the branch circuit breaker (7). In addition, the distance between the buckle claw (37) and the extension piece (36) in the short side direction of the main piece (31) is set so that the hook claw (37) is inserted into the buckle hole (77) to stop The protruding piece (36) reaches the insertion groove portion (72) and is stopped by the slider (74) in the state of the slider. A plurality of elastic retaining members (130a) contacting the output-side end surface of the branch circuit breaker (7) are disposed on the lower front side of the mounting plate (30). Accordingly, it is possible to realize a switchboard in which circuit breakers can be easily attached and detached individually.

Description

technical field [0001] The invention relates to a switchboard equipped with DIN standard circuit breakers. Background technique [0002] Such a switchboard has been described in JP-A-2001-28810. The switchboards mentioned in the bulletin, such as Figure 15 ~ Figure 17 As shown, in the box body 10, a so-called DIN rail 40 for mounting an internal body is disposed. The cross-sectional shape of the DIN rail 40 is U-shaped, and protruding pieces 41 , 41 are extended from the front edges of the two leg pieces in a direction away from each other. Correspondingly, the branch circuit breaker 7 to be installed on the DIN guide rail 40 is formed with a local embedding groove 72 capable of embedding the DIN guide rail 40 at the back of its body, and on the inner side of one of the embedding grooves 72 is formed a The stop slot 73 that can stop the protruding piece 41 on one side of the DIN guide rail 40 from moving is provided on the other inner side of the insertion groove 72, whic...

Problems solved by technology

[0005] But, owing to be to adopt a conductive rod 100 ' to connect the input terminals (power supply side terminals) 79a of each branch circuit breaker 7, so when the branch circuit breakers 7 were separately removed, the conductive rod 100' hindered the connection of the branch circuit breakers 7. In addition, when the branch circuit breaker 7 is installed on the DIN rail 40 again, the conductive rod 100' also becomes an obstacle, making it difficult to separately install the branch circuit breaker 7

[0006] In addition, when the terminals of the branch circuit breaker 7 are connected with electric wires, the slider must be operated to release the slider from the protruding piece 41 of the DIN rail 40, and there will be a slider at the back of the body. When one side of the DIN rail 40 is lifted from the DIN rail 40, the circuit breakers 6 and 7 are moved in the direction of releasing the protruding piece 41 on the other side of the DIN rail 40, so the deformation of the wires may occur.

At this time, when relatively thick wires are used, it is difficult to remove the branch circuit breaker 7 because the wires are not easily deformed. Even if the wires have been deformed, the wires need to be restored when the branch circuit breaker 7 is installed again to the state before deformation, therefore, the work of separately disassembling and attaching branch circuit breakers 7 is very troublesome.
