Therefore, an object of the present invention is to provide a wiring cover mounting structure for a residential power distribution panel that can be easily mounted and locked, and the structure is provided with a wrapping claw at a tip of the wrapping supporting the wiring cover, The covering claws protrude from through holes provided in at least four corners of the wiring cover, and lock mechanisms are provided at least at two lower portions of the periphery of the through hole, and the wiring cover is attached to the box.
[0005]
The lock mechanism used in the mounting structure of the wiring cover is such that a spring is attached to the case, a button portion that can be pushed back to the case by the spring is attached, and the claws protruding from the through hole of the wiring cover are hooked on the button portion. The wiring cover can be fixed to the box.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
In the wiring cover mounting structure for a distribution board for a house according to the present invention, a covering tab is provided at a leading end of the covering for supporting the wiring cover. The wiring cover is provided with a through hole at a position facing the claws. On the upper side of the residential power distribution panel, cover claws are inserted into the through holes and locked with the cover claws. Only the lower side is fixed by the lock mechanism, and a wiring cover is attached to the box.
[0007]
A lock mechanism provided on the lower side of the distribution board for a house attaches a spring to the case and attaches a button portion which can be pushed back to the case by the spring. When attaching the wiring cover, the upper through-hole is hooked on the claws, and then the lower covering claw is inserted into the through-hole of the wiring cover and inserted into the case. When inserted into the case, the hook-shaped claws are locked by hooks inside the case. When the wiring cover is to be removed, the button portion is pressed from below, the locking of the cover claws is released, and the cover claws are removed from the case.

【Example】
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a housing for a distribution board wiring cover for a house according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
In a residential distribution board, electric devices such as a main breaker and a branch breaker are arranged in a box, and a front surface of the box is covered with a wiring cover 2 having a projecting hole 1 through which an operation handle of the electric device can project. The wiring cover 2 is supported by a cover 3 attached to a box. The present invention relates to a mounting structure of the wiring cover 2.
[0010]
The wiring cover 2 is provided with at least two through holes 4, at least two through holes, and two through holes at the bottom. At the tip of the covering 3, a covering claw 5 formed in a hook shape is attached. A lock mechanism 6 for the wiring cover 2 is provided in the lower through hole 4a.
[0011]
When the wiring cover 2 is attached to the box, the upper through-hole 4b of the wiring cover 2 is opposed to the locking portion of the upper claws 6, and the wiring cover 2 is positioned so as to be hooked. After that, the lower through-hole 4 a is made to penetrate through the lower covering tab 5 through the stopper 7. The cover claws 5 are locked by the lock mechanism 6, and the wiring cover 2 can be mounted on the box.
[0012]
An embodiment of a wiring cover mounting structure for a residential distribution board according to claim 2 of the present invention will be described with reference to the accompanying drawings of FIGS.
[0013]
The wiring cover 2 is provided with at least two through holes 4, at least two through holes, and two through holes at the bottom. At the tip of the covering 3, a covering claw 5 formed in a hook shape is attached. A lock mechanism 6 for the wiring cover 2 is provided in the lower through hole 4a.
[0014]
The lock mechanism 6 includes a case 8, a spring 9 attached to the case 8, and a button 10 that can be pushed back to the case 8 by the spring 9.
[0015]
When the wiring cover 2 is attached to the box, the upper through hole 4b of the wiring cover 2 is opposed to the upper claws 5, and the wiring cover 2 is positioned so as to be hooked. After that, the lower through-hole 4 a is made to penetrate through the lower covering tab 5 through the stopper 7. The covering claws 5 are inserted into the lock mechanism 6 while pulling up the button portion 10, and the covering claws 5 are locked to the button portions 10 in a state where the wiring cover 2 is pushed out, so that the wiring cover 2 can be attached to the box. .
[0016]
To remove the wiring cover 2, the button portion 10 is pushed up from below. By pushing up, the locking between the claws 5 and the button portion 10 is released, and the button portion 10 pushes the claws 5 to protrude the wiring cover 2 to the front. When the button portion 10 is released, the wiring cover 2 is held in a state where the lock is released.
[0017]
【The invention's effect】
As described above, the wiring cover mounting structure for a residential distribution board according to the present invention includes the covering claws provided at the tip of the covering that supports the wiring covering, and the covering claws provided at at least four corners of the wiring covering. In this case, a lock mechanism is provided at at least two lower portions of the periphery of the through hole, and the wiring cover is attached to the box body, so that the work of attaching the wiring cover can be simplified and the workability can be improved. In addition, it becomes difficult to come off due to vibration during transportation or the like.
[0018]
The lock mechanism used in the wiring cover mounting structure is such that a spring is attached to the case, a button portion that can be pushed back to the case by the spring is attached, and a claws protruding from the through hole of the wiring cover are hooked on the button portion. Accordingly, the wiring cover can be fixed to the box, so that the work of attaching the wiring cover can be simplified and the workability can be improved. In addition, it becomes difficult to come off due to vibration during transportation or the like. Even when the lock mechanism is removed, the wiring cover is hooked on the upright by the upper wiring cover claws, so that the work can be performed safely and reliably even in places with poor workability such as high places.
