Liquid crystal display screen wire with filtering and shielding function

Abstract

The invention discloses a liquid crystal display screen wire with filtering and shielding function, belonging to a screen wire, the structure thereof includes a screen wire and a screen wire plug, the terminal of the screen wire is connected with the screen wire plug, each screen wire is in three-layer structure, a wire core, a shielding layer and an insulating layer respectively, the outside of the wire core is wrapped with the shielding layer, and the outside of the shielding layer is wrapped with the insulating layer; the screen wire plug comprises a case and a signal pin; the wire core of the screen wire is connected with the signal pin of the screen wire plug, the shielding layer of the screen wire is connected with the case of the screen wire plug; and the screen wire is connected into a three-terminal filter. Compared with the prior art, the liquid crystal display screen wire with filtering and shielding function of the invention has good filtering function and shielding function.

Description

technical field [0001] The invention relates to a screen cable, in particular to a liquid crystal screen cable with filtering and shielding functions. Background technique [0002] Electromagnetic shielding technology is the most effective means to suppress radiation interference. In the current situation where the electromagnetic spectrum is becoming increasingly dense, the electromagnetic power density per unit volume is increasing sharply, and a large number of high- and low-level devices or equipment are used in a mixed manner, which leads to the deteriorating electromagnetic environment of the system, its importance is even more prominent. [0003] At present, in some information security fields, such as the military, armed police, public security, fire protection, telecommunications, government departments and other industries, computers are required to have good anti-radiation and anti-electromagnetic interference capabilities. [0004] There are many types of LCD sc...
