Problems solved by technology

[0003] The shielding structure of computer cables occupies an absolutely important position. Existing computer cables mainly use the method of adding shielding layers to improve anti-interference performance, especially for signal connections between equipment terminals. Multi-layer shielding needs to be added, which increases the cable The weight of the cable is relatively reduced, and the bending performance of the cable is also reduced

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0027] refer to Figure 1-5 , a computer cable with a lightweight shielding structure, including a cable core, a general insulating layer 1 wrapped outside the cable core, a general shielding layer 2 wrapped outside the general insulating layer 1, and a sheath wrapped around the general shielding layer 2 3. The cable core is composed of control wire core 4, twisted wire core 5 and wrapping layer 6. The control wire core 4 is set at the center of the cable core, and the twisted wire core 5 is annularly distributed outside the control wire core 4. The layer 6 is wrapped around the outer ring of the twisted pair core 5, and the general insulation layer 1 is extruded on ...

Abstract

The invention discloses a computer cable with a light shielding structure. The computer cable comprises a cable core, a master insulating layer, a master shielding layer and a sheath layer; the cablecore is composed of a control core, twisted cores and a wrapping layer; the control core is composed of control conductors, a control insulating layer, a control shielding layer and a control rubber sleeve; each twisted core is composed of transmission conductors, transmission insulated sheaths, a twisting wrapping belt, a transmission insulation layer, a transmission shielding layer and a transmission rubber sheath; and each of the master, control and transmission shielding layers is of a double-side coated membrane structure in which the basement membrane is coated with a conducting paint and the other side is coated with an insulating paint. A light PET dielectric film serves as the master, control and transmission shielding layers to form the light shielding structure of the computer cable, the dielectricity is improved greatly, charge accumulation is effectively avoided, and the anti-interference performance of the computer cable is improved; and the bending performance of the cable is ensured, the cable weight is reduced, and the computer cable is worth of popularization.

Description

technical field [0001] The invention relates to the technical field of computer cables, in particular to a computer cable with a light shielding structure. Background technique [0002] Computer cables, especially cables for connection between electronic computers and their automation equipment, have very high requirements for anti-interference. In order to reduce the mutual crosstalk and external interference between circuits, the computer cables adopt shielding structure, and the shielding requirements of the cables are adopted according to different occasions: combined shielding of twisted pairs, general shielding of cables composed of twisted pairs, general shielding after combined shielding of twisted pairs, etc. method. [0003] The shielding structure of computer cables occupies an absolutely important position. Existing computer cables mainly use the method of adding shielding layers to improve anti-interference performance, especially for signal connections between...
