Abstract
The invention discloses an electric appliance cabinet capable of shielding electromagnetic leakage. The electric appliance cabinet comprises a cabinet shell, an installation member, a nut for fastening the installation member to the cabinet shell and a shielding gasket located between the nut and the cabinet shell, wherein the shielding gasket is welded to the inside of the cabinet shell; and the part, which contacts the nut, of the shielding gasket is a smoothly polished shielding region. The electric appliance cabinet has the advantages that: electromagnetic leakage at a door lock and other parts of the electric appliance cabinet can be effectively shielded by arranging the shielding gasket; on the one hand, the shielding gasket is welded with the cabinet shell to prevent electromagnetic leakage; and on the other hand, the smoothly polished shielding region is in close fit with the nut of a fastening door lock and other installation members to prevent electromagnetic leakage.
Description
Technical field
The present invention relates to a kind of electrical equipment bin.
Background technology
Electrical equipment bin inside is installed with a lot of electric elements; Can produce harmful electromagnetic interference in the use; Though the electrical equipment bin adopts the hermetically-sealed construction and the precautionary measures at the main folding positions that produces electromagnetic leakage such as doors; But but fail to prevent effectively electromagnetic leakage with the installation position of electrical equipment bin at for example door lock etc.; Parts such as door lock are fixed on the door-plate through nut, because the door-plate outer surface is the main skin of paint that plays insulating effect, fit-state is undesirable between nut and the skin of paint; Electromagnetic radiation is come out from the slot leakage between nut and the skin of paint, and the electromagnetic leakage at these parts places has the influence that can not be ignored to normal, the safe operation of outside miscellaneous equipment.
Summary of the invention
Goal of the invention: to the problems referred to above, the purpose of this invention is to provide a kind of shielding protection of electromagnetic leakage of the parts installation places such as electrical equipment bin, particularly door lock that shield electromagnetic leakage fully and effectively.
Technical scheme: a kind of electrical equipment bin that shields electromagnetic leakage; Comprise case shell, installed part, said installed part is fastened on the nut on the said case shell; Also comprise the shielding gasket between said nut and the said case shell; It is inboard that said shielding gasket is welded on said case shell, and the part that said shielding gasket contacts with said nut is the level and smooth blind zone of polishing.
Contact area polishing corresponding with said blind zone on the said nut is level and smooth, and shielding gasket is the key point that stops electromagnetic leakage with the tightness degree that contacts of nut, and the contact area polishing is level and smooth, makes the blind zone contact with its applying more closely effectively.
Beneficial effect: compared with prior art; Advantage of the present invention is through the electromagnetic leakage that shielding gasket effectively shields parts installation places such as electric appliance box cabinet door lock is set; Shielding gasket prevents electromagnetic leakage with the welding of case shell on the one hand, and the nut of the installed parts such as level and smooth blind zone and fastening door lock of polishing on the other hand fits tightly and prevents electromagnetic leakage.

Fig. 2 is the structural representation that shielding gasket contacts with nut;
Fig. 3 is the structural representation that nut contacts with shielding gasket.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Shown in accompanying drawing 1-3; A kind of electrical equipment bin that shields electromagnetic leakage comprises case shell 1, installed part 2, installed part 2 is fastened on the nut 3 on the case shell 1, between nut 3 and the case shell 1 shielding gasket 4 is set also; Shielding gasket 4 is welded on case shell 1 inboard; The part that shielding gasket 4 contacts with nut 3 becomes the blind zone 5 of surface smoothing through polishing, and slides through sanding of flat with blind zone 5 corresponding contact areas 6 on the nut 3, and blind zone 5 contacts with contact area 6 fits closely; In order to avoid there is the slit to produce, prevent that electromagnetic radiation from leaking into case shell 1 outside from the composition surface.
Claims (2)
1. electrical equipment bin that shields electromagnetic leakage; Comprise case shell (1), installed part (2), said installed part (2) is fastened on the nut (3) on the said case shell (1); It is characterized in that: also comprise the shielding gasket (4) between said nut (3) and the said case shell (1); Said shielding gasket (4) is welded on said case shell (1) inboard, and the part that said shielding gasket (4) contacts with said nut (3) is the level and smooth blind zone (5) of polishing.
2. the electrical equipment bin of shielding electromagnetic leakage according to claim 1 is characterized in that: it is level and smooth that said nut (3) is gone up contact area (6) polishing corresponding with said blind zone (5).
