Embodiment 1

[0035]In the embodiment of the present invention, the inner conductor of the inner core layer of the coaxial cable is copper, and when the frequency of the transmitted high-frequency signal is 15MHz, then according to It can be seen that the transmission depth of the high-frequency signal in the copper of the inner core layer is 0.02119 mm.

[0036] In this coaxial cable, the thickness of the conductor copper in the inner core layer is determined to be 2 mm or the like.

[0037] Alternatively, in this coaxial cable, the inner core layer is made of copper-clad aluminum, and the thickness of copper and aluminum in the inner core layer is determined according to the principle that the thickness of copper and aluminum is 1:3. The thickness of aluminum is used to make the inner core layer, and the outer layer of the inner core layer is made of copper and the inner layer is made of aluminum.

Embodiment 2

[0039] In the embodiment of the present invention, the inner conductor of the inner core layer of the coaxial cable is copper, and when the frequency of the high-frequency signal in the coaxial cable is 1750MHz, then according to It can be seen that the transmission depth of the high-frequency signal in the copper of the inner core layer is 1.8163×10 -4 .

[0040] In this coaxial cable, the inner core layer is composed of copper-clad zinc alloy. According to the principle that the thickness of copper and alloy is 1:5, the thickness of copper and zinc alloy in the inner core layer is determined. According to the determined copper and aluminum The thickness of the inner core layer is made, and the outer layer of the inner core layer is made of copper, and the inner layer is made of aluminum.

[0041] When other metals or metal alloys with a lower density than the inner conductor and the inner conductor are used as the inner core layer of the coaxial cable, according to the fre...

Abstract

The invention discloses a coaxial cable and a method for manufacturing the coaxial cable, and aims at solving the problems of difficult fixing and mounting, and inconvenient laying of coaxial cables in the prior art. The method comprises the following steps: determining a first thickness of an inner copper conductor of an inner core layer in the coaxial cable, wherein, the first thickness is determined by frequency of a transmission signal in the coaxial cable and attribute information of the inner conductor; selecting a metal or a metal alloy with the density smaller than the inner conductor, and determining a second thickness of the metal or the metal alloy according to the thickness of the inner core layer in the coaxial cable and the first thickness; manufacturing the inner core layeraccording to the first thickness and the second thickness, wherein, the inner conductor is positioned on the outer layer of the metal or the metal alloy; and sequentially manufacturing an insulating layer and an outer skin layer on the outer layer of the inner conductor in the inner core layer. The proposal can help effectively reduce the weight of the coaxial cable, reduce the fixing and mounting difficulty of the coaxial cable, and facilitate the laying of the coaxial cable without changing the transmission signal quality of the coaxial cable.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a coaxial cable and a method for making the coaxial cable. Background technique [0002] With the popularization and diversification of mobile communications, there is a higher demand for network construction. At present, the feeders widely used in the mobile communication industry are basically made of copper. This is because copper has good electrical, mechanical and thermal properties. [0003] The weight of the copper coaxial cable, that is, the feeder is relatively large, so there are high requirements for the installation and fixing of the feeder. Especially for projects that have a large demand for the promotion of feeder lines, such as the promotion of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) base stations of the 3rd Generation Mobile Communications System (3G) Time Division Synchronization , which is 9 times higher than that of t...
