Description

  In the manufacturing process of the electrical equipment storage box, the present invention is designed to prevent coating defects due to air pockets by escaping air when the electrical equipment storage box is immersed in an electrodeposition coating tank and electrodeposition coating is performed. It is related with the air vent hole obstruction | occlusion structure of the electrical and electronic equipment storage box which plugs up the air vent hole provided in.

  The electric and electronic equipment storage box is a thick metal plate material that is bent and welded, and after degreasing and chemical conversion treatment, is then immersed in an electrodeposition coating tank to coat the whole. In this case, air is released when the electrodeposition coating is performed by dipping in the electrodeposition coating tank, and an air vent hole is provided to prevent coating failure due to the air pocket. And since this air vent hole is unnecessary in a product state, it was closed by a closing member provided with an elastic piece (see, for example, Patent Document 1).

    However, when repainting the electrical and electronic equipment storage box, it is necessary to remove the closing member. In this case, since the air vent hole is provided at the corner of the electric / electronic device storage box, the gap between the inner wall of the corner and the elastic piece of the closing member on the inner wall side is narrow, so that the elastic piece is bent. There is a problem that it is difficult to work. This problem can be solved by using only one elastic piece of the closing member and not locking the elastic member on the inner wall side with the elastic piece, and locking it on the opposite side only with the elastic piece.

However, this has the problem that the position of the elastic piece is wrongly attached when the sealing member is attached to the air vent hole.
