Abstract

The invention provides a box body for housing an electric apparatus. In an assembled box body divided into a back plate and a front frame, the deformation of the back plate due to the unevenness of an accommodation part is prevented and the front frame is easily assembled to improve the opening and closing performance of the door. The box body (1) for housing an electric apparatus comprises a back plate (3) arranged on the wall face of a building and a front frame (7) mounted on the front side of the back plate. A door (8) is supported by the front frame (7). The back plate (3) is equipped with a substrate (11) for the installation of electric devices (40) and an installation hole (23) for fastening the mounting screw. A slit (27) is formed around the installation hole (23). A flexible part (28) corresponding to the unevenness of a wall is arranged between the slit (27) and the installation hole (23).

Description

technical field [0001] The invention relates to a box for accommodating various electrical equipment. Background technique [0002] In the past, the box for housing power distribution equipment, control equipment, communication equipment, etc. was generally integrated with a back panel, top panel, bottom panel, left and right side panels, and a door was provided on the front opening to open and close freely. (For example, refer to Patent Document 1). In addition, there is also known a box that is divided into a back panel, a top panel, a bottom panel, and left and right side panels as a whole in order to realize space-saving during storage and transportation, and to allow one person to perform installation work, and place it in the storage area. Assembled sequentially (for example, refer to Patent Document 2).
