Abstract
The utility model discloses an electronic device structure body with high electromagnetic shielding and high anti-seismic properties, which aims at solving the problems of electromagnetic leakage and poor anti-seismic performance of a seam between connecting bodies. The key points of the technical scheme are as follows: two side plates, a baseplate, a rear panel and a front panel frame of an electronic device are connected through welding, and the two side plates, the baseplate, the rear panel and the front panel frame are welded into a whole; and key devices in the structure body are fixed. Annular U-shaped slots with the width of 3mm and the depth of 2mm are respectively formed on planes of the front panel frame and a welded body which are in contact with an upper cover plate, and the U-shaped slots are used for filling wire mesh lining pads which comprise rubber cores and have the diameter of 3mm. When all connectors of the front panel are assembled, annular electromagnetic seal rings need to be mounted. The connectors mounted on the front panel need to be filter connectors. A power supply is mounted in an independent and hermetically sealed metal box, and the metal box is further fixed on the baseplate. The electronic device structure body is applicable to the electronic devices with high requirements on anti-electromagnetic radiation and anti-seismic performance.
Description
Technical field
The utility model relates to electronic apparatus application Environmental Technology field, more particularly, relates to a kind of high electromagnetic shielding, high Shockproof electronic device structure body.
Background technology
Adopt connected modes such as screw connection, riveted joint more at present with class of electronic devices, seldom adopt integral structure, there is electromagnetic leakage unavoidably in the slit between the connector, and current techniques seldom can surpass 60dB in 100kHZ-1GHZ scope inner shield effect; While current device fixedly electronics integrated circuit board adopts the riveted joint double-screw bolt more, and shockproof properties is not good enough.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of high electromagnetic shielding, high Shockproof electronic device structure body are provided.
The technical solution of the utility model is as follows:
Electronic equipment biside plate, base plate, rear board and front panel framework adopt welding manner to connect, and biside plate, base plate, rear board and front panel framework are welded as a whole.This technological means can guarantee sealing fully between each structure member, and the unlikely electromagnetic leakage that causes.The inner Primary Component of structure fixes.
The welding body contact with front panel the plane, weld the body plane that contacts with upper cover plate and respectively open the annular U type groove of a dark 2mm of wide 3mm, this U type groove is used for filling the band rubber core mesh pad of diameter 3mm.After this technology can guarantee that this welding body covers front panel and upper cover plate, its capability of electromagnetic shielding was still very good.
The all connector of front panel all needs to install when assembling and does not have electromagnetic leakage after this technological means of ring-type electromagnetic sealing circle is to guarantee assembling connector.
The connector that is installed on the front panel all need be a filter connector, and this technology can effectively reduce the interference of transmitting by lead in extraneous and the device body.
Power module is installed in independent sealed can the inside, this can is fixed on the base plate again, and this technology can effectively reduce the electromagnetic interference between power module and the internal circuit board.
Simultaneously components and parts big on the power panel are used insulating cement to be solidificated in power supply can the inside, this measure can improve the power unit shock resistance.
Side plate upper mounted plate card stud adopts integral structure, but not current main-stream riveted joint double-screw bolt, this measure can significantly improve this equipment anti-seismic performance.
The a plurality of electric wire fixed mounts of the inner employing of structure, this measure can significantly improve this equipment anti-seismic performance.
The beneficial effects of the utility model are: solved the electronic equipment that current techniques manufactures and designs and seldom can surpass 60dB in 100kHZ-1GHZ scope inner shield effect, simultaneously the limited problem of anti-seismic performance; The present invention can bring up to the shield effectiveness of electronic equipment in the 100kHZ-1GHZ scope more than the 90db, can obviously improve the electronic equipment anti-seismic performance simultaneously.
