[0053] The wave-absorbing ...

Embodiment 3

[0061] See attached figure 1 And attached Figure 4 The difference between this implementation and the first embodiment is that the basic wire base 1 sequentially includes a wire core 101, a spiral bracket 108, an EVA insulating layer 105, an aluminum foil shielding layer 106, an outer silver-plated shielding layer 107, and a nylon shielding layer from the center to the outside. The shockproof layer 109 ; the spiral support 108 is wound on the wire core 101 . The EVA insulating layer 105 is an insulating layer formed of ethylene-vinyl acetate copolymer. The spiral support 108 adopts high-permeability wave-absorbing materials, but different permeability will produce different conduction characteristics.

[0062] The structure of the spiral support 108 utilizes a wave-absorbing support 201 in the basic line base 1, which is directly wound on the surface of the conductor of the main line core 101 in a helical form. Let the conductor and the insulating layer have a certain amou...

Abstract

The invention relates to an anti-vibration, filtering and anti-electromagnetic interference signal line, and belongs to the technical field of signal transmission, which aims at solving the problems of incomplete electromagnetic and electrostatic shielding, inadequate mechanical vibration isolation and consumption, and conduction of high-order harmonic interference caused by electric network entering into the wire rod or interface reflection between devices. The invention comprises a base line base; An n-layer anti-seismic adsorption layer is coated on the base line, each layer of anti-seismicadsorption layer comprises an anti-seismic layer, a plurality of microwave absorbing supports arranged between the anti-seismic layer and the opposite inner layer; a plurality of microwave absorbingsupports are evenly distributed and a cotton yarn anti-seismic outer layer. A microwave absorbing bracket uniformly distributed in each layer is used for realizing the microwave absorbing; Shock protection is realized by silica gel shock-proof layer and microwave absorbing bracket. The single layer or multi-layer anti-seismic absorbing layer makes the anti-seismic and filtering absorbing effect multiply. The multiple absorbing brackets in each layer adopt different magnetic permeability to enhance the absorption and resist the influence of high frequency interference signals in different frequency bands on the conduction of the wire core.

Description

technical field [0001] The invention belongs to the technical field of signal transmission, and in particular relates to a signal line for anti-shock, filtering and anti-electromagnetic interference. Background technique [0002] Wired communication between devices is mostly carried out through signal lines. Commonly used signal cables include data cables, audio cables, telephone cables, network cables, power adapter cables, cables, and optical cables. [0003] At present, most of the wire bodies of commonly used signal wires are circular in appearance, that is, the shape of the cross-section of the wire body is circular. The structure of the round wire body is mostly a plurality of stranded wires, for example, a plurality of copper wires are twisted to form a copper stranded wire, which is individually wrapped with an insulating layer with a certain degree of softness to form multiple core wires, and then the multiple core wires are Stranding, that is, multiple core wires...
