  However, the invention described in Patent Document 1 has a drawback in that it takes time and labor for confirmation and wiring because the electric wire moves during wiring work.

  In addition, the invention described in Patent Document 2 has a drawback in that a plurality of parts for fixing the electric wire are required, so that costs are incurred and work takes time. In addition, since the electric wire is press-connected by the press contact blade, there is a drawback that the electric wire may be damaged.

  In addition, the invention described in Patent Document 3 has a drawback in that a plurality of parts for fixing the electric wire are required, so that the cost is generated and the operation takes time.

  For this reason, the problem to be solved by the present invention is a box body having an opening at least on the front surface, a door covering the opening of the box body, and a device mounting plate fixed inside the box body. To provide a distribution board input / output wire fixing structure that reduces the number of parts required when fixing the input / output wires to equipment attached to the equipment mounting plate, and does not damage the electric wires. It is in.

  The distribution board input / output wire fixing structure of the present invention made to solve the above-mentioned problems is a fixing bracket for fixing an input / output line to a device attached to a device mounting plate fixed inside the box body of the distribution board. And this fixing bracket is fixed to the box body by the same bracket fixing screw together with the device mounting plate.

  According to the distribution board input / output fixing structure of the present invention, a box body having an opening at least on the front surface, a door covering the opening of the box body, and a device mounting plate fixed inside the box body In a distribution board comprising: a fixing bracket for fixing an incoming / outgoing line to a device attached to a device mounting plate, and the fixing bracket is fixed to the box body together with the device mounting plate by the same bracket fixing screw Therefore, it is possible to reduce the cost of the fixing metal and the metal fixing screw for fixing the input / output line.

  In addition, the number of work steps can be reduced because the fixing bracket for fixing the input / output line to the device attached to the device mounting plate is attached to the box body by the same bracket fixing screw as the device mounting plate.

  In the present invention, the structure for fixing the input / output line to the circuit breaker attached to the equipment mounting plate is made possible with a small number of parts and the number of work processes.

Embodiments of the present invention will be described below.
In a distribution board comprising a box body 11 having an opening at least on the front surface, a door body covering the opening of the box body 11, and device mounting plates 12 and 22 fixed inside the box body 11, Fixing brackets 15 and 25 for fixing the input / output lines 13 and 23 to the apparatus 14 attached to the apparatus mounting plates 12 and 22, and grooves 27 provided in the fixing brackets 15 and 25 correspond to the number of the input / output lines 13 and 23.
