Description

Cable and manufacturing method thereof
Technical Field
The present invention relates to a cable and a method for manufacturing the same, and more particularly, to a cable having excellent electrical and mechanical characteristics and a method for manufacturing the same.
Background
Generally, a cable includes a conductor and an insulating layer covering the outer surface of the conductor, the insulating layer being capable of protecting the conductor and providing an insulating effect.
The manufacturing method of the cable in the prior art comprises two methods of extrusion molding, wrapping and the like. As shown in fig. 1, the extrusion molding method comprises: an insulating material is extruded over the outer surface of a conductor 2, the insulating material forming an insulating layer 3 to form a cable 1. As shown in fig. 16, the wrapping method includes: an insulating tape is wound around the outer surface of a conductor, the insulating tape forming an insulating layer to form a cable.
In order to reduce Insertion Loss (dB) in applications where high-speed cables are used for transmission efficiency, it is generally necessary to use a material having a relatively low dielectric constant as an insulating layer, such as insulating materials including polypropylene (abbreviated as PP), polyethylene (abbreviated as PE), perfluoroalkoxy (abbreviated as PFA), Fluorinated ethylene propylene (abbreviated as FEP), and polytetrafluoroethylene (abbreviated as PTFE). The insulating material of the extrusion molding method is made of materials such as polypropylene, polyethylene, fluorinated ethylene propylene copolymer, perfluoroalkyl and the like, and the insulating wrapping tape of the wrapping method is made of materials such as polytetrafluoroethylene and the like.
However, the extrusion molding method has problems in that: the dielectric constant of the insulating layer has a great influence on the performance of high frequency/high speed transmission, so that a foaming material is usually used to reduce the dielectric constant, but the foaming material is not easy to reach the distribution and yield standards during the manufacturing process.
Although the wrapping method can solve the problem of the extrusion molding method, the wrapping device is difficult to control the tension of the insulated wrapping tape wound on the conductor because the insulated wrapping tape made of polytetrafluoroethylene is softer. If the insulating wrapping tape is pulled too tightly by the wrapping device, the insulating wrapping tape is easy to stretch and deform to generate wrinkles. If the insulating wrapping tape is pulled too loose by the winding device, the wrapping property of the insulating wrapping tape is poor, the insulating wrapping tape cannot be tightly bonded, and the adhesion degree of the insulating wrapping tape and the conductor is poor, so that the insulating wrapping tape and the conductor slide. As shown in fig. 17, the insulating layer is significantly deformed and wrinkled, and the roundness is poor, the conductor is eccentric, and the concentricity of the cable is poor. The above problems will result in deterioration of the electrical and mechanical characteristics of the cable.
Disclosure of Invention
The present invention is directed to a cable and a method for manufacturing the same, which can prevent an inner layer from being wrinkled, so that the inner layer can be flatly coated on an outer surface of a first conductor, and improve the adhesion and coating properties between the inner layer and the first conductor.
Another object of the present invention is to provide a cable and a method for manufacturing the same, which can increase the overall structural strength of the cable, and can avoid the problems of deformation of the inner layer and the outer layer, eccentricity of the first conductor, and the like, thereby improving the roundness and concentricity of the cable.
It is a further object of the present invention to provide a cable and a method for manufacturing the same, which is more excellent in electrical and mechanical characteristics than the cable manufactured by the prior art wrapping method.
In order to achieve the above object, the present invention provides a method for manufacturing a cable, comprising the steps of: two sides of an inner layer respectively pass around two sides of a first conductor along a circumferential direction and a reverse direction of the circumferential direction and are mutually combined, so that the inner layer is coated on an outer surface of the first conductor; and an outer layer continuously wound around an outer surface of the inner layer along a length of the first conductor along one circumferential side to form a cable.
In one embodiment, the inner layer includes a first tape, and two sides of the first tape respectively surround two sides of the first conductor along the circumferential direction and the opposite direction of the circumferential direction and are combined with each other, so that the first tape wraps the outer surface of the first conductor.

Preferably, the material of the first wrapping tape is an insulating material.
Preferably, the insulating material is polytetrafluoroethylene.
In one embodiment, the outer layer includes a second wrap strip continuously wrapped around the outer surface of the inner layer along a length of the first conductor along one circumferential edge.
In one embodiment, the outer layer includes a plurality of second tape strips, one of the second tape strips is continuously wound on the outer surface of the inner layer along the length direction of the first conductor along one side in the circumferential direction, and the other second tape strip is continuously wound on an outer surface of the second tape strip in the previous layer along the length direction of the first conductor along one side in the circumferential direction.

The applicant further tested the cables 41,41A of the present invention with cables made by prior art lapping methods for various electrical and mechanical properties. The electrical characteristics were measured by Impedance (Differential Impedance), Insertion Loss (Insertion Loss @13.28G/Hz), and time difference (Skaw), and the Impedance was designed to have a target value of 105 + -5 Ω. The mechanical properties were tested for roundness, wrinkles and flexibility/bendability under the conditions (1) bending radius of 10 XR, (2) bending angle of 180 DEG + -90 DEG, (3) bending speed of 13cycles/min and (4) load of 50 g.

Figure BDA0002939640030000081
from the above table, it can be seen that the cables 41 and 41A of the present invention have several advantages over the cables made by the prior art wrapping method: firstly, the roundness of the cables 41 and 41A is obviously higher and is closer to a circle; secondly, the impedance values of the cables 41 and 41A are closer to a design target value of 105 omega, and the impedance values are more stable; thirdly, the insertion loss of the cables 41 and 41A is less, and the authenticity and integrity of the transmission signal are better; fourthly, the time difference of the cables 41 and 41A is small, misjudgment is not easy to generate, and the error rate is reduced; fifthly, the cables 41 and 41A have better flexibility/bending property and longer service life; sixth, the cables 41 and 41A of the present invention have no wrinkles, and can improve the adhesion and coating properties between the inner layers 20 and 20A and the first conductor 10.
In summary, the inner layers 20 and 20A of the cables 41 and 41A of the present invention are covered on the outer surface of the first conductor 10, so that the inner layers 20 and 20A can be prevented from being wrinkled, the inner layers 20 and 20A can be flatly covered on the outer surface of the first conductor 10, and the adhesion and the covering performance between the inner layers 20 and 20A and the first conductor 10 are improved.

The above results are clearly observed from the gold phase diagram of fig. 18.
Furthermore, the electrical characteristics (e.g., resistance value, insertion loss, time difference) and mechanical characteristics (e.g., roundness, crimp, flexibility/bendability) of the cables 41,41A of the present invention are superior to those of the cables produced by the prior art wrapping method.
