A mode for carrying out the invention is shown below. The electric device storage box of the present embodiment stores the electric device 81 inside the housing. As can be understood from FIGS. 1 to 5, in this electric device storage box, a mounting member 73 on which the electric device 81 is mounted is connected to a mount angle 71 extending in the vertical direction. ing. Further, at least the first anti-vibration member 31 that sandwiches the fixing portion 82 provided in the electric device 81 and extends in the direction of the mount angle, and a part of the fixed portion 82 is interposed between the mount angle 71 and the electric device 81. A second anti-vibration member 32, a part of which is located between the mounting member 73 and the electric device 81, is provided. Therefore, it is possible to suppress the failure of the electric device 81 due to the transmission of vibration or shock applied to the housing.

Here, a basic embodiment of the electric device storage box of the embodiment will be described. The electric device storage box is provided with a housing and a door that can close the opening of the housing, and is configured so that the housing and the door form an outer shape. The housing of the electric device storage box has a skeleton composed of a plurality of frames. Four mount angles 71 are erected near the corners inside the housing, and a large number of mounting holes 72 are formed in the mount angles 71 at a predetermined pitch. The electric device 81 housed inside the housing is only attached to the mounting hole 72 via the screw 92, and some are fixed to the mount angle 71, while others are passed between the plurality of mount angles 71. In some cases, the electric device 81 is mounted on the mounting member 73 and then mounted in the mounting hole 72.

According to the prior art, the vibration or impact applied to the housing is transmitted to the mount angle 103, and further transmitted to the electric device 101 via the mounting screw 104 of the mounting hole and the mounting member 73. Therefore, in the embodiment, in order to prevent vibration or shock from being transmitted to the electric device 81, a vibration isolator member is provided between the mount angle 71 and the electric device 81, and between the mounting member 73 and the electric device 81. There is. The material of the anti-vibration member may be any material such as synthetic rubber, gel material, polymer material, resin material, etc. that absorbs and absorbs vibration, and is not particularly limited.

By the way, the electric device 81 fixed to the mount angle 71 includes a fixing portion 82 extending in the direction of the mount angle in order to fix the electric device 81 to the mount angle 71. In the present embodiment, the first anti-vibration member 31 sandwiches the fixing portion 82 so as to cover the front-rear direction. Further, the first anti-vibration member 31 sandwiching the fixing portion 82 is pressed in the direction of the mount angle 71 by the fixing member 60 fixed to the mounting hole 72 of the mount angle 71, so that the electric device 81 becomes the mount angle 71. It is fixed. If the electric device 81 and the first anti-vibration member 31 are suppressed by the fixing member 60 with respect to the mount angle 71 so that the electric device 81 can be fixed to the mount angle 71, the fixing member 60 is the electric device 81. Not only is it used for fixing the anti-vibration member 31, but it also contributes to preventing the first anti-vibration member 31 from falling off.

The fixing member 60 shown in FIGS. 1 and 3 includes an abutting portion 61 that abuts on the first anti-vibration member 31, and a bent portion 62 formed by bending from both ends of the abutting portion 61 in the direction of the mount angle 71. An extension portion 63 formed by further bending in the vertical direction from the end portion of the bent portion 62 is provided. In this way, the fixing member 60 shown in FIGS. 1 and 3 is configured to form a hat cross section.

The first anti-vibration member 31 is housed in the space formed by the contact portion 61 and the bent portion 62 of the fixing member 60. The length of the bent portion 62 of the fixing member 60 is preferably shorter than the thickness (horizontal length) of the first anti-vibration member 31.

By the way, if the bent portion 62 is too long, the first anti-vibration member 31 sandwiching the fixed portion 82 cannot be pressed. Further, if the bent portion 62 is too short, the first anti-vibration member 31 is pressed too much, which hinders the function of absorbing / mitigating the vibration. That is, it is preferable that the length of the bent portion 62 is such that the first anti-vibration member 31 sandwiching the fixed portion 82 can be pressed down to the extent that it does not fall. The extension portion 63 is fixed by using a screw 92 inserted into the mounting hole 72 of the mount angle 71.

In the embodiment, the first anti-vibration member 31 has a substantially U-shaped cross section. By covering the fixing portion 82 of the electric device 81 from the left-right direction with the first anti-vibration member 31, the fixing portion 82 can be inserted into the recess. The first anti-vibration member 31 may have any shape as long as it abuts on the front surface and the back surface of the fixing portion 82 of the electric device 81 and sandwiches the fixing portion 82. For example, by covering the first anti-vibration member 31 from above the fixed portion 82 of the electric device 81, the fixed portion 82 is inserted into the recess, and the first anti-vibration member 31 It may be something to prevent falling off. Further, the first anti-vibration member 31 may have a shape that covers all of the front / rear, left / right, and vertical directions of the fixing portion 82. By covering each direction of the fixing portion 82, it is possible to prevent vibration from being transmitted to the electric device 81 from all directions.

Next, vibration isolation between the mounting member 73 and the electric device 81 will be described. In the example shown in FIG. 1 and the like, the mounting member 73 is attached so as to cross between the mount angles 71 located in the front-rear direction of the housing. As can be seen from FIG. 4, in this example, the mounting member 73 has an L-shaped cross section, and the electrical device 81 can be mounted on a mounting surface extending in the direction perpendicular to the mount angle 71. it can. Further, since the second anti-vibration member 32 is arranged on the mounting surface so that the second anti-vibration member 32 is interposed between the mounting surface and the electric device 81, the second anti-vibration member 32 is arranged via the mounting member 73. It is possible to suppress the transmission of vibration or shock to the electric device 81. As can be understood from FIG. 5, the second anti-vibration member 32 may be provided over one surface of the mounting surface, but is partially provided at the four corners of the electric device 81. You may do so.

Next, vibration isolation of the mount angle 71 and the electric device 81 will be described. The electric device 81 is fixed via the mounting hole 72 of the mount angle 71 in a state of being mounted on the mounting member 73, but is mounted on the side surface of the electric device 81 in order to facilitate mounting the electric device 81. A gap is provided between the angle 71 and the inner surface of the angle 71. A third anti-vibration member 33 may be arranged in this gap. As can be understood from FIG. 6, if the mount angle 71 is provided with the third anti-vibration member 33 on the surface facing the electric device 81, the influence of vibration on the electric device 81 is further increased. It can be suppressed.

When an impact or vibration is applied to the housing, the first anti-vibration member 31 acts on the vibration in the front-rear direction and the second anti-vibration member 32 acts on the vibration in the vertical direction to protect the electric device 81. However, by forming the third anti-vibration member 33 on the surface of the mount angle 71 facing the electric device 81, the electric device 81 can be protected from vibration in the left-right direction and the like. The third anti-vibration member 33 may be fixed to the mount angle 71, or may be integrally formed with the second anti-vibration member 32 and upward from the second anti-vibration member 32. It may be stretched.

Here, the fixing member 60 used for pressing the second anti-vibration member 32 against the mount angle 71 will be described including an example different from the above. In the above example, the fixing member 60 extending in the vertical direction is used, and the fixing portion 82 of the electric device 81 and the first anti-vibration member 31 are supported by the extending portion 63 of the fixing member 60 extending in the vertical direction. This has the effect of preventing the first anti-vibration member 31 from falling. Such a configuration is sufficient when the number of electric devices 81 mounted on the housing is small, but when it is desired to increase the number of electric devices 81 mounted on the housing, the extension portions 63 are placed above and below the electric devices 81. The configuration of fixing with screws at the position may be inconvenient for arranging the electric devices 81 in the vertical direction.

On the other hand, as shown in FIG. 7, the cross section is substantially L-shaped, which is composed of an abutting portion 66 that abuts on the first anti-vibration member 31 and a bent portion 67 formed by bending one end of the abutting portion 66. If the bent portion 67 is fixed to the side surface of the mount angle 71 via a screw 93, the fixing member 60 can be formed within the vertical size range of the electric device 81, and the electric device 81 can be formed. There is no limit to the amount of storage.

Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be in various modes. For example, the housing may be made of only a plate material instead of forming a skeleton with a frame.
