Abstract
The invention discloses a semi-flexible radio-frequency coaxial cable. The semi-flexible radio-frequency coaxial cable comprises an inner conductor, an insulator, an outer conductor and a sheath which are coaxially arranged in sequence from inside to outside, wherein an isolating layer is arranged between the insulator and the outer conductor and is a fluorine plastic film layer or a metal composite foil layer. According to the semi-flexible radio-frequency coaxial cable, the isolating layer is additionally arranged between the insulator and the outer conductor and isolates the insulator from the outer conductor, the insulator is prevented from making direct contact with the outer conductor, and therefore the metal weave layer serving as the outer conductor is prevented from being embedded into the insulator and being stripped from the insulator difficultly. Meanwhile, as the outer conductor adheres to the isolating layer and the insulator does not adhere to the isolating layer together, in the process of wire stripping, the outer conductor and the isolating layer are both stripped from the insulator easily.

The beneficial effect that the present invention produces is: in half soft radio frequency coaxial-cable of the embodiment of the present invention, by additional isolation layer between insulator and outer conductor, by insulator and outer conductor isolation, avoid both directly to contact, thereby prevent from can being embedded in insulator as the wire sheathing of outer conductor, cause outer conductor to be difficult to peel off from insulator.Meanwhile, because outer conductor sticks on separator, and insulator can not adhere to each other with separator, thereby in wire stripping process, outer conductor is easy to peel off from insulator together with separator.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of half soft radio frequency coaxial-cable in prior art;
Fig. 2 is the structural representation of half soft radio frequency coaxial-cable in the embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 2 shows the structural representation according to half soft radio frequency coaxial-cable of the embodiment of the present invention, compare with the half soft radio frequency coaxial-cable of the prior art shown in Fig. 1, this half soft radio frequency coaxial-cable also comprises separator 5 between insulator 2 and outer conductor 3, for isolated insulation body 2 and outer conductor 3, make can directly not contact between insulator 2 and outer conductor 3.
From material, say, this separator 5 is fluorine plastic film layer or metal composite foils layer.Particularly, when separator 5 is fluorine plastic film layer, fluorine plastic film layer is polytetrafluoroethylene (PTFE) thin layer or perfluoroethylene-propylene (FEP) thin layer.When separator 5 is metal composite foils layer, metal composite foils layer is that plastic-aluminum combined paper tinsel layer or copper are moulded composite insulating foil layer.Certainly, above material is only used for example, in the situation that not departing from protection range of the present invention, can select other applicable fluoroplastics or metal composite foils to prepare separator 5.In addition, the fluorine plastic film adopting in the present invention or metal composite foils are any applicable fluorine plastic film or the metal composite foils that can sell on the market.Take metal composite foils as example, optional by the extend various applicable metal composite foils of unit preparation of Shanghai.
From structure, say, the thickness of separator 5 is generally less than or equals 0.5 millimeter, is preferably less than or equal to 0.05 millimeter, and the best is 0.033 millimeter.Can, according to the model of cable, select the separator 5 that is applicable to thickness.
From preparation method, say, separator 5 is wrapped separator 5 or vertical bag separator 5.Wrapped or vertical packet preparation method does not have substantive difference for the performance impact of separator 5, can select applicable preparation method according to actual conditions.
In addition, in half soft radio frequency coaxial-cable of the embodiment of the present invention, preferably, insulator 2 is solid fluoroplastic insulation body or foaming fluoroplastic insulation body or lotus root core fluoroplastic insulation body; Wherein, this fluoroplastic insulation body is polytetrafluoroethylene (PTFE) insulator or perfluoroethylene-propylene (FEP) insulator.
