Description

[0001]
[Industrial application fields]
The present invention relates to a breaker fixing structure for a distribution board in which a panel on which a main breaker or a branch breaker is mounted is attached to a base.
[0002]
[Prior art]
In the conventional breaker fixing structure in the distribution board, the screw hole 23 is provided in the terminal portion 22 of the breaker 21, the screw 24 is inserted from the screw hole 23, and the breaker 21 is screwed to the panel 25.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional breaker fixing structure has a drawback that it takes time to tighten the screw and the workability is poor. Further, since the tip of the screw 24 protrudes under the panel 25, the wiring may be damaged.
[0004]
[Means for Solving the Problems]
Therefore, the present invention has an object to provide a breaker fixing structure that can be easily attached to the breaker and has good workability. The structure is provided with a notch in the vicinity of the breaker mounting position of the panel. fit the fixed part, the structure of the stationary part includes a retainable fitting portion to the panel fitted in notches to form a fixing portion for fixing the breaker, a load-side connection terminals of the fixed portion breaker The breaker is fixed to the panel by fitting into a convex portion provided at the lower part of the surface.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Breaker fixing structure of the distribution board according to the present invention, is held by fitting the notch in the fixed part provided on the panel in the panel, the convex portion provided to move the mounting bracket to the lower side of the Breaker Insert the fixing part and fix the breaker to the panel.
[0006]
【Example】
An embodiment of a breaker fixing structure for a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
As shown in FIG. 1, a breaker 1 housed in a distribution board is fixed to a panel 2. A notch 3 is provided near the breaker mounting position of the panel 2. A fixed part 4 is rotatably attached to the notch 3.
[0008]
As shown in FIG. 2, the fixing component 4 forms a fitting portion 5 that can be fitted into the notch 3 and a fixing portion 6 that fixes the breaker 1. The fixing part 6 is provided with a holding part 7 for holding the breaker 1 with elasticity.
[0009]
The fitting part 5 of the fixing part 4 is fitted into the notch 3 of the panel 2 and the fixing part 4 is rotatably attached. In order to attach the breaker 1 to the panel 2, the breaker 1 is placed at the attachment position, the fixing component 4 is rotated, and the convex portion 8 provided at the lower portion of the surface having the load side connection terminal of the breaker 1 is fixed to the fixing portion 6. The pinching part 7 is fixed with scissors. To remove the breaker, as shown in FIG. 3, a jig such as a driver 9 is inserted between the breaker and the fixed component 4, and the fixed component 4 is rotated.
[0010]
A second embodiment of the breaker fixing structure for a distribution board according to the present invention will be described with reference to the attached drawing of FIG.
[0011]
The breaker 10 that is housed in the distribution board is fixed to the panel 11. A notch 12 is provided in the vicinity of the breaker mounting position of the panel 11. A fixing component 13 is attached to the notch 12.
[0012]
The fixing component 13 forms a fitting portion 14 that can be fitted into the notch 12 and a fixing portion 15 that fixes the breaker 10. The fixing part 15 is provided with a clamping part 16 for clamping the breaker 10 by elasticity.
[0013]
The fitting part 14 of the fixing part 13 is fitted into the notch 12 of the panel 11 so that the fixing part 13 is slidably mounted. In order to attach the breaker 10 to the panel 11, the breaker 10 is placed at the attachment position, the fixed component 13 is slid, and the convex portion 17 provided at the lower portion of the surface having the load side connection terminal of the breaker 10 is fixed to the fixing portion 15. The pinching part 16 is fixed with scissors.
[0014]
【The invention's effect】
As described above, the breaker fixing structure of the distribution board according to the present invention is provided with a notch in the vicinity of the breaker mounting position of the panel, the fixing part is fitted into the notch, and the structure of the fixing part is notched. To form a fitting part that can be fitted and a fixing part for fixing the breaker, and to fix the breaker to the panel by fitting the fixing part into the convex part provided on the lower part of the surface having the load side connection terminal of the breaker The breaker can be easily fixed to the panel with only the fixing parts. Also, since there are no protrusions such as screws, the wiring space under the panel is not affected.
