Abstract
Disclosed is a sub-high temperature semi-flexible coaxial cable, comprising an internal conductor, an insulating layer, an outer conductor, and a sheath layer, wherein the exterior of the internal conductor is sequentially covered by an insulating layer, an outer conductor, and a sheath layer; the insulating layer is made of the poly-4-methyl-1-pentene foaming material; and the outer conductor comprises a copper foil longitudinal package and a metal wire braid ply. The sub-high temperature semi-flexible coaxial cable features stable structure and good shielding property, reaches the heatproof requirement of 150 DEG C, is easy to weld and install, and has high coupling degree with the connector.
Description
Technical field
The utility model belongs to field of cables, is specifically related to a kind of inferior high temperature semi-flexible coaxial cable.
Background technology
Signal transmission in the market mainly is divided into two types with radio frequency coaxial-cable: one type is the common polythene foamed coaxial cable, and its serviceability temperature reaches-55～85 ℃, is suitable for general base station, indoor covering construction; Another kind of is main high-temperature coaxial cable for sending out polytetrafluoroethylene, and such cable temperature resistant grade is higher, and serviceability temperature can reach 200 ℃; But the employed material cost of such cable is than higher, and wherein one and half gentle high-temperature coaxial cables are used for short distance connection between oscillator in the antenna, because of the frequent welding and the transmission requirement of upper frequency; Use it that heatproof is required to have brought up to certain degree; But because of higher material cost, and slower process velocity, the utilance of the course of processing is lower; Cause such cable price high especially, thereby improved the overall cost of antenna.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, and a kind of inferior high temperature semi-flexible coaxial cable is provided.
Technical scheme: in order to achieve the above object; The utility model is specifically realized like this: a kind of inferior high temperature semi-flexible coaxial cable; Comprise inner wire, insulating barrier, outer conductor and restrictive coating; Inner wire is covered with insulating barrier, outer conductor and restrictive coating outward successively, and insulating barrier is the poly 4-methylpene-1 expanded material; Outer conductor comprises vertical bag of Copper Foil and wire braid.
Wherein, said inner wire is single or many silver-coated copper wires.
Wherein, one deck wicking layer is arranged on the wire braid.
Beneficial effect: the utility model Stability Analysis of Structures, advantages of good shielding performance, the heatproof that has reached 150 ℃ requires, is prone to welding, and is strong with the connector matching, easy for installation.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
