The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

The novel coaxial line of the utility model, as shown in fig. 1-2, comprises a conductor 1, an insulating layer 2 and a shielding layer 3. The insulating layer 2 is arranged on the outer surface of the conductor 1; the shielding layer 3 comprises a copper strip winding layer, and the copper strip winding layer is arranged on the outer surface of the insulating layer 2. In the structure, the shielding layer 3 adopts a copper strip winding layer to replace a copper wire winding layer and a belting layer in the prior art; on the premise of not influencing the electrical performance, the material cost is effectively reduced; simple structure and convenient production and processing.

Preferably, the conductor 1 is made of copper or copper alloy material; the conductor 1 can be composed of a copper wire or a copper alloy wire, or a plurality of copper wires or copper alloy wires are twisted into a whole.

Preferably, the insulating layer 2 comprises a plurality of insulating material layers, which are sequentially stacked; the insulating material layer is an insulating plastic layer. In the structure, when the insulating layer 2 comprises an insulating material layer, the insulating layer is made of an insulating material; when the insulating layer 2 comprises several layers of insulating material, each layer of insulating material is made of a different material and then laminated together. The mode of using multilayer insulating material to laminate is favorable to using the material that the dielectric constant is outstanding at the inlayer to the electric property of reinforcing coaxial line, and uses functional plastics at the skin and makes the electric wire more high temperature resistant, or adds look mother at the skin and makes the wire rod have more colours and distinguish in order to make subsequent processing, has avoidd the adverse effect of look mother to electric property simultaneously again. The insulating plastic layer may be made of one of fluorinated ethylene propylene resin, polyethylene and polypropylene, or may be made of other existing plastic insulating materials.

Preferably, the thickness of the flat copper strip is greater than 0.001mm and less than 0.1 mm; the width of the flat copper strip is greater than 1mm and less than 8 mm. In the structure, the thickness of the shielding layer 3 has a significant influence on high-frequency electrical performance such as attenuation performance of the coaxial line, and therefore the shielding layer 3 needs to have a certain thickness to obtain good electrical performance; the thickness of the copper strip is more than 0.001mm, the copper strip starts to have positive influence on the attenuation performance, and the thickness of the flat copper strip can be flexibly adjusted, so that the whole thickness of the shielding layer can be adjusted according to the actual condition of the electrical performance. The copper wire with the diameter of about 0.1mm can be pressed into a flat shape, so that the flat copper strip with the required specification is obtained, and the processing technology is simple.

Preferably, the copper strip winding layer is formed by winding a flat copper strip. In the structure, the width of the flat copper strip is wider than that of a copper wire used for winding the copper wire layer in the prior art, so that the number of winding turns required in winding processing is reduced, and the material cost is effectively reduced.

Preferably, the winding mode of the flat copper strip is spiral winding; the flat copper strip comprises a plurality of turns 31, between two adjacent turns 31, the edge of the previous turn 311 having the edge of the next turn 312 overlapping the outer surface thereof. By adopting the structure, the flat copper strip can be ensured to completely cover the insulating layer 2, so that the insulating layer 2 is completely shielded.

In the prior art, about 50 copper wires with the diameter of 0.05mm are wound on the outer surface of the insulating layer 2 to form a copper wire winding layer; however, the copper wires are only close to each other and do not have a firm and tight structure, and the copper wires are combined together by a wrapping tape layer containing a copper layer on the outer layer to form an effective shielding layer; therefore, when the wire is bent or the winding process is unstable, gaps are easily generated among the copper wires, and leakage points of signals are generated; the conventional tape layer has a copper layer thickness of 1U or less, and does not have an absolute shielding effect. In this embodiment, the flat copper tape completely covers the insulating layer 2, does not generate a leakage point, has sufficient thickness, and can meet the electrical performance requirement.

Preferably, the shielding layer 3 comprises a plurality of copper strip winding layers, and the plurality of copper strip winding layers are sequentially arranged from inside to outside by taking the insulating layer 2 as an axis. With the structure, when the shielding layer 3 needs to be adjusted, the thickness of the copper strip during pressing can be changed, and multiple layers of copper strip winding layers can be stacked, so that the thickness of the shielding layer 3 can be freely adjusted.

It should be noted that by adjusting the thickness of the flat copper strip, compared with the copper wire winding layer in the prior art, the actual amount of copper material used is reduced, the material can be effectively saved, and the copper-containing belting layer with a complex preparation process is not needed, thereby reducing the production cost.

Compared with the prior art, the novel coaxial line adopts the copper strip winding layer to replace the copper wire winding layer and the belting layer in the prior art; on the premise of not influencing the electrical performance, the material cost is effectively reduced; simple structure and convenient production and processing. The novel coaxial line has the characteristics of low cost and simple structure.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the utility model.
