Description

The present invention relates to a residential distribution board comprising a rail laid on a base having a through hole on the bottom surface, a device mounting panel provided on the rail, and a main breaker / branch breaker arranged on the device mounting panel. It is about.

The residential distribution board 31 includes a base 32 and a cover body constituting a housing, a main breaker mounting panel 33, and a branch breaker mounting panel 34. The base 32 of the conventional residential distribution board 31 has a bottom surface 32a as a wall surface mounting portion, and is provided with mounting holes (not shown) and outgoing wire holes 35. An electric device 36 such as a breaker is placed on the device mounting panels 33 and 34 attached to the base 32. The equipment mounting panel 33 on which the main breaker 36a is placed is formed in a size that does not cover the through hole 35 provided in the bottom surface 32a of the base 32, and the electric wire drawn from the through hole 35 is attached to the equipment. On the panel 33, it was connected to the terminal portion of the main breaker 36a.
Japanese Patent No. 3212844

  Since the device mounting panel 34 is mounted on the base 32, the main breaker 36 a is naturally mounted at a position raised from the bottom surface of the base 32. Therefore, the thickness of the housing of the residential distribution board 31 is occupied by the device mounting panel 34. In particular, a large space is required to bend a thick electric wire connected to the main breaker 36a, but it cannot be secured sufficiently. There was a drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide a residential distribution board capable of securing sufficient wiring space and wiring work space with a simple structure, and the structure is a device for mounting a main breaker. The size of the mounting panel is made smaller than the main breaker, and in order to secure the wiring space and wiring work space, it is not protruded from the upper end part of the power supply side terminal and the lower end part of the load side terminal of the main breaker To do.

The distribution board for houses according to the present invention is such that the size of the device mounting panel for placing the main breaker is made smaller than that of the main breaker, and in order to secure the wiring space and the wiring work space, the power supply side terminal of the main breaker The upper end of the cable and the lower end of the load side terminal are prevented from coming out, so when connecting the wires inserted from the bottom of the housing, the space for placing the wires and the space for connecting the wires are It can be sufficiently secured on the upper part of the breaker, and the efficiency of the wiring work of the residential distribution board can be improved.

  A residential distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

The residential distribution board 1 is provided with a large through hole 2 on the bottom surface, and a rail 5 is attached to a frame-shaped base 4 that forms the side surface portion 3, and a device mounting panel 6 is attached to the rail 5 . the equipment mounting panel 6 is placed an electrical device such as a main breaker 7 and branch breakers 8. A front opening 9 of the residential distribution board 1 is surrounded by a cover body 10, and a cover body 13 having a window through which the operation handle 11, display 12, etc. of the main breaker 7 and the branch breaker 8 can be confirmed is attached. Furthermore, the door body 14 is covered and configured.

  On the residential distribution board 1, a device mounting panel 6 b for the branch breaker 8 is installed adjacent to the device mounting panel 6 a for the main breaker 7. A fixing hole 15 is formed in each of the device mounting panels 6a and 6b, and is opposed to a screw receiving portion (not shown) provided on the base 4 and fixed by screwing. Further, connection holes 16 are also provided in the connection portions 6c of the device mounting panel 6, and the device mounting panel 6a for the main breaker 7 and the device mounting panel 6b for the branch breaker 8 are connected by screwing or the like.

  The device mounting panel 6a for mounting the main breaker 7 according to the present invention is composed of a main breaker mounting portion 6c, a fixing portion 6d, and a connecting portion 6e, and the main breaker mounting portion 6c is smaller than the size of the main breaker 7. When viewed from the front, the size of the device mounting panel 6a does not protrude from the main breaker 7 from the end of the power supply side terminal 7a.

  The base 4 constituting the housing of the residential distribution board 1 has a large through hole 2 on the bottom surface, and all the through hole 2 portions can be used as through holes. An electric wire inserted at an arbitrary position of the through hole is connected to the power supply side terminal 7 a of the main breaker 7. The electric wire connected to the power supply side terminal 7a for taking in the commercial power is thicker than the electric wire wired in other parts such as the load side terminal 7b of the main breaker 7, and there is a wide space even when bent when being routed in the casing. In the present invention, the device mounting panel 6a for placing the main breaker 7 is made smaller than the main breaker 7 so that a sufficient wiring space and wiring work space can be secured.
