Door-opening shielding device of magnetic shielding equipment case/ cabinet

Abstract

The invention provides a door-opening shielding device of a magnetic shielding equipment case / cabinet. The door-opening shielding device of the magnetic shielding equipment case / cabinet comprises a cabinet body and an equipment installation framework arranged in the cabinet body, the cabinet body and the equipment installation framework are connected to form a closed equipotential body, and the door-opening shielding device of the magnetic shielding equipment case / cabinet further comprises conductive fabric arranged between the equipment installation framework and the inner surface of the cabinet body and a shielding spring leaf assembly arranged on the mounting flange surfaces of the equipment installation framework. The shielding spring leaf assembly comprises an upper shielding spring leaf, a lower shielding spring leaf, a left shielding spring leaf and a right shielding spring leaf, wherein the upper shielding spring leaf is arranged on the upper framework mounting flange surface of the equipment installation framework, the lower shielding spring leaf is arranged on the lower framework mounting flange surface of the equipment installation framework, and the left shielding spring leaf and the right shielding spring leaf are arranged on framework mounting flange surfaces of the two sides of the equipment installation framework respectively. The door-opening shielding device of the magnetic shielding equipment case / cabinet is simple in structure, can be directly improved on an ordinary metal equipment cabinet, has good electromagnetic shielding effectiveness, does not influence the operation of the equipment in the equipment case / cabinet, and has no influence on the operation performance and heat dissipation effect of the equipment case / cabinet and the equipment.

Description

technical field [0001] The invention relates to an electromagnetic shielding case / cabinet, in particular to a door-opening shielding device for the magnetic shielding case / cabinet. Background technique [0002] At present, the requirements for electromagnetic shielding in the fields of electronics, communication, testing, and control are constantly improving, so the application range of chassis / cabinet products with electromagnetic shielding function is becoming more and more extensive; but the traditional electromagnetic shielding chassis / cabinets are all through the overall The closed way realizes the complete equipotential shielding cavity of the cabinet body to electromagnetically shield the equipment in the cabinet; but this device requires the cabinet / cabinet to be closed in the working state, and the equipment with monitoring and operation requirements It is very inconvenient, and the electromagnetic shielding effect is lost after the door is opened, so it is impossib...

[0002] At present, the requirements for electromagnetic shielding in the fields of electronics, communication, testing, and control are constantly improving, so the application range of chassis / cabinet products with electromagnetic shielding function is becoming more and more extensive; but the traditional electromagnetic shielding chassis / cabinets are all through the overall The closed way realizes the complete equipotential shielding cavity of the cabinet body to electromagnetically shield the equipment in the cabinet; but this device requires the cabinet / cabinet to be closed in the working state, and the equipment with monitoring and operation requirements It is very inconvenient, and the electromagnetic shielding effect will be lost after opening the door, so it is impossible to achieve both convenient operation and electromagnetic shielding

[0003] The current solution in the industry is to transfer the display screen, sockets and operation buttons on the box / cabinet door, which requires modification and secondary processing of the equipment in the cabinet. The transfer process is complicated, the design and processing are difficult, and a large number of The transfer line causes electromagnetic interference between internal devices and interferes with the cooling air duct of the chassis / cabinet, which has a certain impact on performance and life
