Abstract
A polytetrafluoroethylene medium semi-soft coaxial radio frequency cable is characterized in that an inner conductor, a medium layer, an outer conductor and an outer jacket are coaxially arranged in the cable from inside to outside, wherein the inner conductor adopts a single silver plated copper-clad steel wire, the medium layer adopts polytetrafluoroethylene, the outer conductor is formed through weaving tin-plated copper wires and then being coated by tin layers, the outer jacket is a polytetrafluoroethylene raw material strip lapped layer processed by high-temperature fuse sealing. The cable can prevent leaking, has low degeneration, small standing wave ratio, small volume, light weight and low cost, has good high-temperature resistance, low-temperature resistance, bending performance,electrical performance and mechanical performance, and can satisfy the use requirements of high-frequency 20 GHz communication system.
Description
Technical field
The utility model relates to cable, is particularly suited for " black box ", mobile communication base station, delay line and microwave, mobile radar equipment and adopts the electronic equipment of similar high frequency, super high frequency technique.
Background technology
In recent years, the develop rapidly of China's Aero-Space cause, mobile communication system, high speed computer system, medical electronic and relevant supporting information industry thereof, all kinds of high frequency communication systems also improve day by day to the specification requirement of cable.Because the particularity of environment for use, then require the cable anti-leak, decay is low, standing-wave ratio is little, volume is little, in light weight, price is low, and has good high temperature resistant, low temperature resistant, bendability, electric property, mechanical performance etc.Existing radio frequency cable, high temperature resistant and poor performance at low temperatures, the dielectric constant of cable dielectric in use changes with the variation of working temperature and frequency, has increased the transmission attenuation and the reflection loss of cable, influences the normal use of cable.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of anti-leak is provided, decay is low, standing-wave ratio is little, volume is little, in light weight, price is low, and PTFE medium half flexible coaxial radio frequency cable with good high temperature resistant, low temperature resistant, bendability, electric property and mechanical performance, to satisfy the user demand of high frequency 20GHz communication system.
The utility model technical solution problem adopts following technical scheme:
Coaxial from inside to outside inner wire, dielectric layer, outer conductor and the oversheath of being provided with of the utility model;
Described inner wire adopts single silver-copper plated steel clad wire, and dielectric layer adopts polytetrafluoroethylene, and outer conductor is to weave dip-coating tin layer with tinned wird to form again; Oversheath is the polytetrafluoroethylraw raw material band lapping layer of high temperature sealing by fusing.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the inner wire in the utility model adopts single silver-copper plated steel clad wire, has both improved the resistance to corrosion of inner wire, has improved the mechanical strength and the shock resistance of inner wire again, and has effectively saved the copper metals resources; Dielectric layer adopts polytetrafluoroethylene, has improved the stability of signal of telecommunication cable transmission under high low temperature and broadband state; Outer conductor weaves dip-coating tin layer with tinned wird again and forms, and compares stability and the consistency with better screen effect and signal transmission than the conductor of not dip-coating tin layer after braiding, has effectively improved the operating frequency and the transmission performance of cable; Oversheath adopts polytetrafluoroethylraw raw material band wrapped, and the high temperature sealing by fusing makes product have flexibility, moistureproof moist, anti-salt fog characteristics.
2, the utility model anti-leak, decay is low, standing-wave ratio is little, volume is little, in light weight, price is low, be easy to promote the use of.
3, the utlity model has good high temperature resistant, low temperature resistant, flexibility, electric property and mechanical performance, do not need complicated flector, can manually be shaped arbitrarily; And can repeat to change shape and the performance that do not influence cable, it is very convenient to construct.
4, the utlity model has than the higher operating temperature range of PTFE medium semihard coaxial radio frequency cable, can match with the connector of same specification PTFE medium semihard coaxial radio frequency cable.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 inner wire, 2 media, 3 outer conductors, 4 oversheaths.
Below pass through embodiment, and in conjunction with the accompanying drawings the utility model is further specified.
Embodiment
Referring to Fig. 1, coaxial from inside to outside inner wire 1, dielectric layer 2, outer conductor 3 and the oversheath 4 of being provided with of present embodiment;
Wherein, inner wire 1 adopts single silver-copper plated steel clad wire, both can improve the resistance to corrosion of inner wire, has improved the mechanical strength and the shock resistance of inner wire again, and has effectively saved the copper metals resources;
Dielectric layer 2 adopts polytetrafluoroethylene, has improved the stability of signal of telecommunication cable transmission under high low temperature and broadband state;
Outer conductor 3 is to weave dip-coating tin layer with tinned wird to form again, and compares stability and the consistency with better screen effect and signal transmission than the conductor of not dip-coating tin layer after braiding, has effectively improved the operating frequency and the transmission performance of cable;
Oversheath 4 is the polytetrafluoroethylraw raw material band lapping layer, and adopts the high temperature sealing by fusing, and this makes product have performances such as good softness, protection against the tide and anti-salt fog.
