Abstract
The utility model discloses a radiation protection type coaxial cable. The radiation protection type coaxial cable comprises an inner conductor, an insulating layer, a copper foil layer, a braided layer and a sheath layer from inside to outside. A polyimide thin film layer is arranged between the inner conductor and the insulating layer. A polyimide thin film layer is arranged between the braided layer and the sheath layer. The braided layer is a tinned copper wire braided layer. The outer sheath layer is made from a polytrifluorochloroethylene material. According to the utility model, through the polyimide thin film added outside the inner conductor, the electromagnetic leakage in the high-frequency power condition in the process of transmission can be prevented, and the outside of the braided layer of the outer conductor is coated with a polyimide thin film at the same time, so the external radiation interference can be prevented, and especially the infringement of secondary cosmic rays after the cosmic rays enter the atmosphere.
Description
Technical field
The utility model relates to a kind of cable, and particularly a kind of radiation-proof coaxial cable belongs to technical field of electric wires and cables.
Background technology
Coaxial cable is a kind of transmission line of transmitting high-frequency signal, and its coaxial kernel of section is circular inner wire, is the tubular outer conductor around circular inner wire, is provided with insulating barrier between two conductors.Because internal and external conductor is in coaxial position, like this so that the electromagnetic field of high frequency in coaxial line, transmit.
The important parameter of weighing coaxial cable is its shielding and anti-interference, and common inner conductor adopts the insulation of PE layer, and aluminium foil is outer conductor, and the magnalium silk is woven shield, and shield effectiveness is poor, and the signal of transmission is undesirable.
The utility model content
The utility model purpose provide a kind of simple in structure, can prevent that built-in field from leaking and can prevent the coaxial cable of external radiation.
Scheme of the present utility model is as follows: a kind of radiation-proof coaxial cable, comprise from inside to outside inner wire, insulating barrier, copper foil layer, braid, restrictive coating, be provided with polyimide film layer between described inner wire and insulating barrier, also be provided with polyimide film layer between described braid and the restrictive coating.
Described braid is tincopper fuse wire braided armor.
Described external sheath layer adopts the polytrifluorochloroethylene material to make.
The beneficial effects of the utility model:
1, the outer polyimide film that increases of inner wire, the electromagnetic field under the high frequency power that can prevent from transmitting leaks.
2, the braid outer cladding polyimide film of outer conductor can prevent that outside radiated interference, especially cosmic ray from entering the infringement of the secondary cosmic rays behind the atmosphere.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of radiation-proof coaxial cable, comprise from inside to outside inner wire 1, insulating barrier 2, copper foil layer 3, braid 4, restrictive coating 5,2 of described inner wire 1 and insulating barriers are provided with polyimide film layer 6, also are provided with polyimide film layer 6 between described braid 4 and the restrictive coating 5.
Described braid 4 is tincopper fuse wire braided armor.
Described external sheath layer 5 adopts the polytrifluorochloroethylene material to make.
The utility model is when implementing, and inner wire 1 coats one deck polyimide film 6 synchronously in 2 layers of plastic extruding insulateds; The outer conductor Copper Foil of coaxial line coats one deck polyimide film layer 6 synchronously with machine when adding tincopper fuse wire braided armor 4; Above-mentioned processing step and other technique are carried out synchronously, do not increase operation, also just do not increase human cost, so that this coaxial line cost is reasonable, cost performance is high.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
