Description
Technical field
The utility model relates to a kind of concentric cable, particularly relates to a kind of height of resistance to high pressure phase stabilization indoor test line concentric cable.
Background technology
Concentric cable is the cable general name of transmission signal or energy in radio-frequency band. Main be used as transmit by radio or receiving equipment antenna feeder and various communication, the machine intraconnections of electronics or be interconnected line. Conventional concentric cable is made up of inner conductor layer, insulation layer, screen layer and restrictive coating. Wherein insulation layer is by PTFE(tetrafluoroethylene) push the puffing material stretched, in order to the guarantee of transmission performance, PTFE puffing material is generally raw material, and nodeless mesh between the molecule of raw material and molecule, inner air content height, its proof voltage poor-performing, is generally 300 to 600 volts, some high pressure places cannot be applicable to, it may also be useful to there is limitation. There is the defect being difficult to peel off in the restrictive coating of conventional coaxial cable in addition when needing to peel off. Therefore a kind of height of resistance to high pressure phase stabilization indoor test line concentric cable that can be applicable to high pressure place is sought particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of height of resistance to high pressure phase stabilization indoor test line concentric cable that can be applicable to high pressure place.
The purpose of this utility model is achieved in that
A kind of height of resistance to high pressure phase stabilization indoor test line concentric cable, it is characterized in that it comprises inner conductor layer from the inside to the outside successively, Withstand voltage layer, insulation layer, first outer conductor layer, 2nd outer conductor layer and restrictive coating, described inner conductor layer is silver-plated copper wire twisted wire, described Withstand voltage layer is that heatproof FEP or PFA has extruded, the thickness of described Withstand voltage layer is 0.06 ~ 0.3mm, described insulation layer is that PTFE pushes the expanded bed of material stretched, described first outer conductor layer is silver-plated flat wire-wound covering, described 2nd outer conductor layer is silver-plated round silk braid, described restrictive coating is FEP or PFA extrusion molding layer. wherein restrictive coating comprises internal layer restrictive coating and outermost sheath layer, described internal layer restrictive coating surface is provided with one embedding slot, it is disposed with from the inside to the outside in embedding slot and fills rope and cutting steel wire, the surface of described cutting steel wire is provided with insullac, the outside surface of described internal layer restrictive coating is provided with the many stiffening webs being evenly arranged, and the position that stiffening web avoids embedding slot is arranged.
Compared with prior art, the beneficial effects of the utility model are:
The utility model height of resistance to high pressure phase stabilization indoor test line concentric cable is owing to adding, at inner conductor layer and insulation layer, the Withstand voltage layer that thickness is 0.06 ~ 0.3mm, its proof voltage performance is improved greatly, can reaching more than 1000 volts, therefore this height of resistance to high pressure phase stabilization indoor test line concentric cable has the advantage that can be applicable to high pressure place.
Accompanying drawing explanation

Embodiment
See Fig. 1 ~ Fig. 2, a kind of height of resistance to high pressure phase stabilization indoor test line concentric cable that the utility model relates to, it comprises inner conductor layer 1, Withstand voltage layer 2, insulation layer 3, first outer conductor layer 4, the 2nd outer conductor layer 5 and restrictive coating 6 from the inside to the outside successively. described inner conductor layer 1 is silver-plated copper wire twisted wire, described Withstand voltage layer 2 is heatproof FEP(fluorinated ethylene propylene copolymer) or PFA(tetrafluoroethylene perfluorinated alkoxy vinyl ether copolymer) extrude and become, the thickness of described Withstand voltage layer 2 is 0.06 ~ 0.3mm, the expanded bed of material that described insulation layer 3 becomes for PTFE pushes stretching, described first outer conductor layer 4 is silver-plated flat wire-wound covering, silver-plated flat wire-wound covering has high fragrance stability, during bending, transmission speed change is little, described 2nd outer conductor layer 5 is silver-plated round silk braid, described restrictive coating 6 is FEP or PFA extrusion molding layer.
Wherein restrictive coating 6 comprises internal layer restrictive coating 6.1 and outermost sheath layer 6.2, described internal layer restrictive coating 6.1 surface is provided with one embedding slot 6.3, being disposed with from the inside to the outside in embedding slot 6.3 and fill rope 6.4 and cutting steel wire 6.5, the surface of described cutting steel wire 6.5 is provided with insullac. The outside surface of described internal layer restrictive coating 6.1 is provided with the many stiffening webs 6.6 being evenly arranged, and the position that stiffening web 6.6 avoids embedding slot 6.3 is arranged, and the setting of stiffening web 6.6 can improve the strength of joint between internal layer restrictive coating 6.1 and outermost sheath layer 6.2. When needing to peel off restrictive coating, it is only necessary to cut at cable end, filling rope 6.4 is wound on cutting steel wire 6.5, then cutting steel wire 6.5 is outwards torn and can be peeled off by restrictive coating.
