Problems solved by technology

The sheath layer made of ordinary polyvinyl chloride plastic has strong permeability and is easily affected by moisture, which will cause internal oxidation, affect normal signal transmission, and shorten the service life of the entire cable
The traditional cable core is generally wrapped around the cladding, and the core is easy to deviate from the original set position when the external extrusion is relatively strong.

Embodiment Construction

[0011] Such as figure 1 As shown, a three-core twisted pair cable for a computer includes a core conductor 1 and a sheath 8 wrapped around the core conductor 1. The core conductor 1 is formed by twisting three insulated cores. The core conductors 1 are closely arranged in pairs, and the wrapping layer 3 , the shielding layer 4 , the insulating layer 6 and the waterproof layer 7 are sequentially arranged between the core conductors 1 and the sheath 8 .

[0012] As a further solution of the present invention: the reinforcing member 2 is wrapped between the wrapping layer 3 and the core conductor 1 .

[0013] As a further solution of the present invention: the insulated wire core is composed of a wire core twisted with a plurality of oxygen-free annealed annealed copper wires, a crust layer wrapped outside the wire core, and an outer conductor braided with nickel-plated copper wires.

[0014] As a further solution of the present invention: the shielding layer 4 is also wrapped w...

Abstract

The invention discloses a three-core twisted-pair cable for a computer. The three-core twisted-pair cable comprises cable core conductors and a sheath coating the exteriors of the cable core conductors, wherein a wrapping layer, a shielding layer, an insulating layer and a waterproof layer are arranged between the cable core conductors and the sheath in sequence; each cable core conductor is formed by three insulating cable cores in a pair-twisting manner; the cable core conductors are tightly arranged in a two-by-two external tangent manner; the cable core of each cable core conductor comprises a cable core twisted by multiple strands of anaerobic annealing soft copper wires, a skin-forming layer coating the exterior of the cable core, and an external conductor woven by nickel-plated copper wires. The cable is wide in application, high in conductivity, high-temperature-resistant, anti-dragging, good in shielding performance, waterproof, oil-resistant, winding-resistant, anti-breaking, and firm in cable cores, and mainly applied to the fields of computers and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a three-core pair twisted cable for computers. Background technique [0002] At present, with the continuous increase of cable consumption, high requirements are also put forward for the quality of cables. For example, cables for instruments have particularly high requirements for high temperature resistance, waterproof and oil resistance, drag resistance, acid and alkali resistance, corrosion resistance and anti-interference. The sheath layer made of ordinary polyvinyl chloride plastic has strong permeability and is easily affected by moisture, which will cause internal oxidation, affect normal signal transmission, and shorten the service life of the entire cable. The traditional cable core is generally wrapped around the cladding, and the core is easy to deviate from the original set position when the external extrusion is relatively strong. [0003] Only by meeting the requirements can...
