The present invention relates to a coupling between an external housing (11) and a mounting plate (20) constituting a wall-mounted control panel or a distribution board, wherein the coupling between the housing (11) and the mounting plate (20) The member is made of rubber or urethane which can absorb vibration.

As shown in Fig. 2, the housing 11 of the distribution board 10 is fixed to the wall by a fixing screw 1 with a buffer material 2 interposed therebetween.

3, one side of the back plate 12 of the housing 11 is cut and then bent to the opposite side of the wall so that a pair of housing protrusions 13 are formed. At the place where the housing protrusion 13 is cut, (13-1) are formed. The housing protrusion 13 is cut by using the back plate 12 of the housing 11, and then bent by 90 degrees so that no additional parts are added.

Then, the screw fastening portion 14 is fixed by welding to the center of the pair of arm protrusions 13. The screw fastening portion 14 is a means for fastening the attachment plate 20 to the housing 11.

Since the mounting plate 20 is located inside the distributor box 10 and the main electrical parts are fixed, the vibration insulating member 30 is mounted to prevent the mounting plate 20 from being prevented from functioning due to earthquake, So that they are fixed to each other between the plate 20 and the housing 11.

 The housing protrusion 13 formed on the back plate 12 of the housing 11 of the distribution board 10 is formed adjacent to a portion fixed to the wall by the fixing screw 1 and is coupled with the dustproof member 30, And the vibration generated between the housing and the housing is absorbed.

It is preferable that the positions where the housing protrusions 13 are formed are formed adjacent to the four fixing screws at which the distribution board 10 is fixed.

The mounting plate 20 is fixed to the back plate 12 by a fastening screw 40 inside the housing 11 and the fastening screw 40 is screwed and fixed to the screw fastening portion 14. [ At this time, the washer 35 is interposed and fixed. The washer 35 is made of plastic in order to block electricity from reaching the inner surface of the screw hole.

One side of the plate of the mounting plate 2 is cut and then bent toward the wall to form a pair of protrusions 22. The protrusions 22 are engaged with the anti-vibration member 30. A screw hole 21 is formed at the center of the pair of projections 22 so that the screw portion of the fastening screw 40 is inserted and engaged with the screw fastening portion 14.

The vibration preventing member 30 has a through hole 33 passing through the front and back at the center of the rectangular body 31 and the screw coupling portion 14 described above is positioned in the through hole 33.

The mounting plate engaging grooves 32 are formed on the upper and lower sides of the through hole 33 at one side of the body 31 of the anti-vibration member 30, and the protrusions 22 of the mounting plate 20 are inserted and fixed. The housing fixing groove 34 is formed at an intermediate position between the through hole 33 and the mounting plate engaging groove 32 on the other side of the other side of the body 31 on which the mounting plate engaging groove 32 is formed, Is inserted and fixed.

The vibration preventing member 30 is made of a urethane material or a rubber material and is provided with a threaded fastening portion 14 inside the through hole 33. The threaded fastening portion 14 has a cylindrical vibration proof rubber The space between the screw engagement portion 14 and the through hole 33 can be selectively filled.

Here, the housing 11 and the mounting plate 20 are combined so as not to come into direct contact with each other. The housing protrusion 13 is formed by bending a part of the back plate constituting the housing and the housing fixing groove 34 of the vibration preventing member 30 is fitted and fixed to the housing protrusion 13 .

The projections 22 facing the back plate 12 of the housing 11 are formed by bending the surface of the mounting plate 12 like the housing 11 so that the projections 22 can be attached to the mounting surface of the vibration- And inserted into the plate engaging groove 32 to be fixed.

Therefore, the housing and the mounting plate are not fixed directly but the anti-vibration member is positioned in the middle. At this time, the anti-vibration member 30, the housing protrusions 13, and the protrusions 22 are formed in a rectangular shape so that they are pressed and pressed between the projections in the vertical direction in the vertical direction. As shown in Fig. 6, this structure can absorb the vibration in the vertical direction well.

Vibration in the horizontal direction is also absorbed easily because the housing fixing groove 34 and the mounting plate engaging groove 32 are engaged with the housing protrusions 13 and the protrusions 22 in a state of being meshed with each other.

Since the mounting plate and the housing are separated by the anti-vibration member which is an insulator, even if the circuit breaks due to the vibration transmitted to the mounting plate, the anti-vibration member prevents current from being transmitted to the external housing, It has the effect of preventing damage.
