And a front lid (front door) 5 attached to the.

The housing body 1 has a shield plate 6 in the side opening 2 thereof.
A recess 7 is provided so that the shield plate 6 is attached, and a large number of screw holes 8 are formed in the recess surface. The shield plate 6 is screwed into the screw insertion hole 9 and screwed into the screw hole 8. Is openably and closably attached to the recess 7.

The casing body 1 is integrally formed by welding by combining structural steel plates and shaped steels having appropriate plate thicknesses, and the essential points to be grounded including the recessed surface 7 are, for example, hot dip galvanized. The metal surface such as is exposed, and the other inner and outer surfaces are appropriately finished by painting.

The shielding plate 6 attached to the housing body 1 as described above is also a similar steel plate and is plated similarly, so that the side opening 2 is reliably electrically shielded by the shielding plate. This prevents electromagnetic waves from entering and leaving the external space. Therefore, the side surface lid body 3 may be formed by appropriately applying a suitable number of screws, and for example, the four corners may be attached to the housing body 1 so as to be openable and closable, and only the appearance is maintained. Although such a configuration is shown on the right side in the figure, the left side in the figure is similarly configured.

A shield member 11 made of an electrically conductive and elastic material is attached to the peripheral surface forming the front opening 4 of the housing body 1 so that the inner periphery of the front cover 5 comes into contact with the peripheral surface. Has become.

Below the right end of the front lid 5 in the figure is the housing body 1.

(Not visible), the front cover 5 can be opened and closed by using the pin shafts 12 and 13 as spindles.

A handle 14 is provided at the center of the left side of the front lid 5 in the figure.
Is provided, and when the handle 14 is operated, the tip of a rod-shaped locking member 15 that is provided so as to interlock with the inner surface side and moves up and down respectively is provided with a hole 16 ( (Only the lower side is shown), the front lid 5 is locked to the housing body 1 and the front opening 4 is closed.

The peripheral surface of the front opening 4 is plated with the same metal as the surface of the recess 7 of the side opening 2. The front lid 5 is made by bending a structural steel plate having an appropriate thickness, the inner surface of the front lid 5 is also plated with the same metal, and the other parts are painted and finished. It is what

Since the shielding member 11 is a long tube having a circular cross section and contains a conductive material, the front cover member 5 is formed.
