Problems solved by technology

During manufacturing, it is difficult to ensure the concentricity between the conductor and the first and second insulating layers; and the eccentricity caused by insufficient concentricity makes the impedance of the cable fluctuate greatly
The mismatch of impedance causes a part of the signal to be reflected to the transmission source at a specific frequency, so that the signal is lost, and return loss occurs.
The concentricity of the cable and the cylindricity of the cable core are poor, which causes the signal to radiate outward on the one hand, and on the other hand, there i

Example Embodiment

[0034] Implementation mode one: if figure 1 As shown, the Teflon (Teflon) insulating sheath 3 with an outer diameter of 6.2±0.3mm is composed of four pairs of cables twisted together to form a pair and each pair has a different twist distance. The wires are all composed of a conductor cable core 1 with an outer diameter of 0.58 mm and an insulating sheath 2 with an outer diameter of 0.95 mm. The conductor cable core 1 is made of a stretched steel core 11 coated with a copper coating layer 12 and then plated with a silver layer 13 ( see image 3 ), the insulation sheath is also equipped with cross-section foamed Teflon (Teflon) packing, which separates each pair of twisted signal lines from each other; the total lay length is 130±5mm; the insulation sheath 2 is made of Teflon Dragon (Teflon) made.

Example Embodiment

[0035] Embodiment 2: Except that the cable core is replaced by silver-plated copper, other structures and materials are the same.

Example Embodiment

[0036] Embodiment 3: Except that the cable core is replaced by bare copper, other structures and materials are the same; the surface roughness of the bare copper is relatively low.

[0037] The aforementioned cables can be made by the following processes:

[0038] 1. The production process of silver-plated copper-clad steel cable core:

[0039] 1) Stretch φ6.0mm billet into φ2.2mm steel bar;

[0040] 2) Stretching the φ2.2mm steel bar and simultaneously annealing it to obtain a stretched steel core 11 with an outer diameter of 0.5mm;

[0041] 3) Copper-clad steel continuous extrusion cladding (refer to the paper "Research on continuous extrusion cladding of copper-clad steel contact wire billet" 10006 Yun Xinbing 116028 Song Baoyun Liu Yuanwen) The basic principle of continuous extrusion cladding is to use friction as the driving force Carry out extrusion; on the basis of the continuous extrusion process method, the shoe seat is placed on the upper part of the extrusion whee...

Abstract

A high speed data communication cable used on network is prepared as forming cable by four pairs of cable lines as each pair being prepared by twisting two cable lines and being covered with insulation protective sheath, forming each signal line by conductor cable core and insulation cover, packing Teflon or PE material with cross form section in insulation protective sheath and applying copper covered steel conductor as conductor cable core and using flame proof CMP Teflon to prepare insulation protective sheath and insulation cover.

Description

technical field [0001] The invention relates to a signal transmission cable, in particular to a high-speed and high-performance data communication cable for a network and a manufacturing process thereof. Background technique [0002] In the utility model whose announcement number is CN2266183, the announcement date is October 29, 1997, and the name is a high-speed high-performance data communication cable for computer network, it is disclosed that it is composed of eight cables with the same structure, and every two cables are twisted together. Become a pair, and set an outer sheath on the outside of the four pairs. Each cable is composed of a conductor, a first insulating layer, a second insulating layer, and a color ring. The transmission performance of the utility model is greatly improved, the transmission rate reaches 100Mbps, and the distributed capacitance is small, the attenuation is reduced, and the anti-crosstalk ability is strong. [0003] The publication number ...
