Description

[Detailed description of the invention] This invention relates to a mounting device for the side plate of the panel, and in particular,
The present invention relates to a mounting device for side plates of a panel body such as a power distribution board or a control panel, and for connecting a plurality of adjacent panels so that they can be separated and independently.

In conventional panels used for control panels, etc., a lipped groove-shaped (hereinafter referred to as groove-shaped) side plate with a bent end in the width direction is attached between the top frame and the bottom frame. There is. However, in such a board side plate, only the lip portion on the groove-shaped opening side contacts the top frame and the bottom frame. For this reason, simply fastening the lip portions to the top frame and the bottom frame using screw attachment members or the like is insufficient in terms of strength, since the side plates of the disk body made of thin steel plates also serve as supports for the disk body. Moreover, when a plurality of unit board base frames are connected and provided as one body, only the adjacent board side plates are connected. There is a groove-shaped space between the top frame and the bottom frame, and since the side plates of the board are made of thin steel plates, the connection strength is weak against vibrations and shocks. Further, there is a drawback that it is not easy to tighten a plurality of unit board bodies with screw members.

Therefore, the main purpose of this invention is to allow the side plates of the panel body connecting the top frame and the bottom frame to be easily and firmly attached using the mounting screw members, and to connect the base frames of the unit panel bodies. It is an object of the present invention to provide a mounting device for side plates of a board that can facilitate connection and separation of unit boards when provided.

To summarize, this idea is to form a board connecting hole at a position corresponding to the top frame and bottom frame of the board side plate, and attach a boss member having a tap hole aligned with the board connecting hole to the board. Attaches integrally to the side plate. A board side plate mounting bolt having a through hole formed in its center is screwed into the tap hole of the boss member from inside the top frame and the bottom frame.
