Abstract
The invention discloses an electrical apparatus case electromagnetic shielding structure comprising a top plate, side plates and a bottom plate. The adjacent side plates are mutually connected; one side plate of the adjacent side plates is provided with an L-shaped groove along the edge in an extending manner; the other side plate connected therewith is provided with a bent convex edge along the edge in an extending manner; and the bent convex edge is inserted in the L-shaped groove in the other side plate. The further improvement is that the bent convex edge of the side plate is embedded in the L-shaped groove in the other side plate. The structure at the junction of the adjacent side plates can increase absorption and reflection of electromagnetic waves in the L-shaped groove of the side plate, thereby preventing electromagnetic wave from leaking.
Description
Technical field
The present invention relates to a kind of shielding casing of electric instrument.
Background technology
Along with the progressively intensification of people to electromagnetic leakage, hazards of electromagnetic radiation understanding, the existing means that start to adopt in a large number various anti-electromagnetic leakages, electromagnetic radiation, wherein adopting electromagnetic shielding instrument cabinet is one of conventional means.For the cabinet of side cover-opening structure, in order to reach the electromagnetic effect of shielding, prior art is to make every effort to the gap of cabinet reduce as far as possible, but after cabinet is shut, from the joint of adjacent side plates, still exist certain gap, cause electromagnetic leakage, after particularly frequency is greater than 1HZ, problem is more outstanding.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of electric apparatus cabinet electromagnetic armouring structure with better shielding electromagnetic wave effect.
The present invention is achieved through the following technical solutions technical goal.
Electric apparatus cabinet electromagnetic armouring structure, comprise top board, side plate, base plate, adjacent side plate interconnects, its improvements are: in described adjacent side plate, side plate extends and is provided with L shaped groove along edge, another side plate being attached thereto extends the chimb that is provided with bending along edge, the chimb of this bending inserts in the L shaped groove of another side plate.
The present invention further improves and is: the chimb of described side plate bending embeds in the L shaped groove of another side plate.
The present invention compared with prior art, has following good effect: the structure of adjacent side plates joint can increase the absorption reflection of electromagnetic wave at the L shaped groove of side plate, thereby prevents electromagnetic-wave leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the I part partial enlarged drawing in Fig. 3.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Electric apparatus cabinet electromagnetic armouring structure shown in the drawings, comprise top board 1, side plate 2 and side plate 3, base plate 4, adjacent side plate 2, side plate 3 interconnect, in adjacent side plate 2, side plate 2 extends and is provided with L shaped groove along edge, the side plate 3 that another is attached thereto extends the chimb that is provided with bending along edge, the chimb of this bending inserts in the L shaped groove of another side plate 2, and in the present embodiment, the chimb of side plate 2 bendings embeds in the L shaped groove of another side plate 2.Like this, utilize the structure of adjacent side plates 2 and side plate 3 joints can increase the absorption reflection of electromagnetic wave at the L shaped groove of side plate 2, thereby prevent electromagnetic-wave leakage.
Claims (2)
