Abstract

The invention discloses an electronic equipment case. The electronic equipment case comprises a shell, a cover plate and an anti-EMI (Electro Magnetic Interference) structure, wherein the cover plate is arranged on the shell; the shell is provided with a connector for plugging external electronic equipment; the anti-EMI structure comprises a first contact member and a second contact member; the first contact member comprises a first connection part and first contact pieces; the first connection part is connected to a side edge of the anti-EMI structure; the first contact pieces are connected to the two ends of the first connection part; the anti-EMI structure is provided with a through hole which is matched with the connector; the second contact member comprises a second connection part and second contact pieces; the second connection part is connected to the edge of the through hole; the second contact pieces are connected to the second connection part; the anti-EMI structure is fixedly arranged on the cover plate; when the cover plate is arranged on the shell, the first contact pieces are abutted against the shell, and the second contact pieces are abutted against the part, protruding out of the through hole, of the connector.

Description

technical field [0001] The invention relates to an electronic equipment case, in particular to an electronic equipment case with a better effect of preventing electromagnetic interference. Background technique [0002] In recent years, with the rapid development of electronic products, the problem of electromagnetic interference of electronic products has become more and more prominent. Electromagnetic Interference (EMI for short) refers to the interference phenomenon caused by the interaction between electromagnetic waves and electronic components. There are two types of conducted interference and radiated interference. Conducted interference refers to the coupling (interference) of a signal on one electrical network to another electrical network through a conductive medium. Radiation interference refers to the interference source coupling (interference) its signal to another electrical network through space. In high-speed PCB and system design, high-frequency signal line...
