Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method of mounting a wiring cover for covering the electric devices, wiring, and the like in a distribution board including various electric devices housed in a box body.
[0002]
[Prior art]
A wiring cover attached to a conventional distribution board is often attached so that it can be opened and closed by a rotating operation. Further, when a space for opening and closing the wiring cover by rotating operation is not sufficient, such as in a pipe shaft room or a room dedicated to electric equipment, the four corners of the wiring cover are attached by turning fingers with screws having knobs (for example, See Patent Document 1.).

[Problems to be solved by the invention]
However, according to the above-described conventional method of attaching the wiring cover of the distribution board, the screw must be turned many times with a finger at the time of attachment and detachment, which is very troublesome. Since the wiring cover is fixed only by screws, positioning is difficult, and when the wiring cover is large, it is very difficult for one person to attach the wiring cover. In addition, the wiring cover is provided with an opening to expose the internal device, but there is some clearance in the mounting hole for attaching the screw, depending on the mounting method, the opening does not face the device, There is a disadvantage that the wiring cover cannot be fixed.
[0005]
[Means for Solving the Problems]
Therefore, an object of the present invention is to provide a wiring cover mounting method for a distribution board which can easily attach and detach a wiring cover and can surely cover a wiring, and the structure thereof is a lower box of the wiring cover. A mounting bracket having an insertion pin is provided on the body side, and a lower receiving bracket capable of supporting the insertion pin is mounted on the box body, the wiring cover is opposed to the box body, and the insertion pin is received on the lower receiving body. The wiring cover is attached to the box body by inserting the wiring cover into a metal fitting.
[0006]
Further, a locking portion operated by a knob provided on a surface is attached to an upper portion of the wiring cover, and an upper receiving metal fitting to which the locking portion can be locked is provided in the box body.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the method for attaching a wiring cover of a distribution board according to the present invention, an upper receiving portion and a lower receiving portion are provided in a box body of the distribution board, and the wiring cover is insertable into the lower receiving portion. A mounting member having a pin formed thereon and a locking member for locking the upper receiving metal member are provided. The locking tool has a knob on the front surface of the wiring cover, and a locking section is provided on the back surface at a position facing the upper receiving bracket, so that the locking section locks the upper receiving bracket by the operation of the knob. It has become. The insertion pin of the wiring cover is inserted into the lower receiving portion, the locking tool is locked to the upper receiving metal fitting, and the wiring cover is attached to the box body.
[0008]
【Example】
An embodiment of a method for mounting a wiring cover on a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
According to the wiring cover mounting structure for a distribution board according to claim 1 of the present invention, in a distribution board in which an electric device such as a breaker is mounted on the box body 1 and wiring is performed between the electric devices, A wiring cover 2 is attached to the opening 1a to cover electric equipment and wiring. A lower receiving metal fitting 3 is provided below the peripheral edge of the box body opening 1a. The lower receiving metal fitting 3 has an insertion hole 3a and has a shape capable of temporarily supporting the wiring cover 2. At the position of the wiring cover 2 facing the lower receiving metal fitting 3, the mounting bracket 4 on which the insertion pin 4 a is formed is fixed by screwing from the back surface of the wiring cover 2.
[0010]
The wiring cover 2 is attached by inserting an insertion pin 4a of a mounting member 4 provided on the wiring cover 2 into an insertion hole 3a of the lower receiving metal member 3, and positioning and supporting the wiring cover 2. As it is, the upper side of the wiring cover 2 is also pressed and fixed to face the opening 1a.
[0011]
In the wiring cover mounting structure of the distribution board according to the second aspect of the present invention, the upper receiving metal fitting 5 is provided above the peripheral edge of the box body main body opening 1a. The upper receiving member 5 is provided with, for example, a locking hole 5a. On the other hand, the wiring cover 2 is provided with a locking member 6 at a position facing the upper receiving member 5 provided on the box body 1. The locking member 6 has a knob 6a on the surface of the wiring cover 2, and a locking portion 6b is provided on the back surface of the wiring cover 2. By operating the knob 6a, the locking portion 6b is locked to the upper receiving member 5. It is possible.
[0012]
The wiring cover 2 is attached by inserting an insertion pin 4a of a mounting member 4 provided on the wiring cover 2 into an insertion hole 3a of the lower receiving metal member 3, and positioning and supporting the wiring cover 2. The upper side of the wiring cover 2 is also pressed as it is, and the knob 6a on the surface of the wiring cover 2 is operated to lock the locking portion 6b to the upper receiving metal fitting 5 of the box body 1 and fix it.
[0013]
The wiring cover 2 can be removed by releasing the lock 6a with the knob 6b provided on the wiring cover 2 from the upper receiving metal fitting 5, lifting the wiring covering 2 as it is, and lowering the insertion pin 4a with the lower receiving metal fitting. Pull out from 3.
[0014]
The method of attaching the wiring cover according to the present invention is not limited to the above-described method. It can be changed appropriately within the range.
[0015]
Further, the mounting bracket and the locking tool used in the present invention may have a shape that can be used even in the case of a revolving door type in which the wiring cover can be opened and closed by a rotation operation. For example, as the mounting bracket, insertion pins are formed on both upper and lower sides, a hinge receiving bracket is mounted on the box body side, and the insertion pin is inserted into the hinge receiving bracket and rotated as a hinge for use. In addition, the locking tool can be shared with a part for fixing the wiring cover other than the hinge side of the revolving door type wiring cover.
[0016]
【The invention's effect】
As described above, the wiring cover mounting method according to the present invention provides a mounting method in which an insertion pin is formed on the lower box side of the wiring cover, and the box body can support the insertion pin. Attach the side bracket, make the wiring cover face the box body, insert the insertion pin into the lower bracket, and attach the wiring cover to the box body. There is no need to hold it floating, it is easily installed and can be done by one worker. Positioning can be reliably performed when the wiring cover is attached. The screw is not exposed on the surface, and the aesthetic appearance can be maintained.
[0017]
In addition, the upper part of the wiring cover is equipped with a locking part that operates by a knob provided on the surface, and the box body has an upper receiving bracket that can lock the locking part. The wiring cover can be easily removed simply by pulling out the wiring cover diagonally upward without the trouble of rotating the screw many times, which facilitates the work of mounting and removing.
