Description
Technical field:
The utility model relates to a kind of cable, particularly relates to a kind of expanded microporous polytetra fluoroethylene-EPTEE soft radio frequency cable that insulate.Be generally used for Military Electronic Equipment and relevant civilian microwave equipments such as communication, electronics tracking, warning, electronic countermeasures, navigation, high frequency connecting line.Belong to the telecommunication cable technical field.
Background technology:
Radio frequency cable is the cable general name of interior transmission of electric signals of radio-frequency band or energy.Wherein most widely used is coaxial cable, mainly as the machine intraconnections of the feeder of radio transmission or receiving equipment and various communication, electronic equipment or interconnect line.Before the utility model was made, existing coaxial cable such as SFF type were pushed insulating barrier, outer conductor silver-plated single line individual layer woven shield and sheath skin by inner wire heart yearn, solid PTFE usually and are formed.Though modern cables manufacturing development of technology has been improved the antijamming capability of cable greatly, adapted to the transmission demand of high-speed data communication and LAN (Local Area Network).But it also comes with some shortcomings: big as loss, shielding and anti-interference are poor, and especially the telecommunication cable electrical property is subject to shortcomings such as natural environment and climate condition influence, makes its scope of application enjoy restriction, can not use at high-frequency range.Frequency generally is no more than 3G, and transmission attenuation is big: 0.52 (dB/m), cable is stiff.Along with the continuous development of national defence weapon equipment and microwave communication, and the demand of civilian intelligent microwave instrument, telecommunication transmission is more and more urgent to the requirement of radio frequency cable attenuation and voltage standing wave ratio.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, and little, the low standing wave of a kind of transmission attenuation, cable softness, shielding and the good expanded microporous polytetra fluoroethylene-EPTEE of the anti-interference soft radio frequency cable that insulate is provided.
The purpose of this utility model is achieved in that a kind of expanded microporous polytetra fluoroethylene-EPTEE soft radio frequency cable that insulate, and successively by inner wire heart yearn, insulating barrier, outer conductor screen and sheath skin, it is characterized in that from the inside to the outside:
A) it is wrapped that described insulating barrier adopts micropore PTFE multilayer, and the teflon insulation that has air can reduce the transmission attenuation and the loss of cable;
B) described outer conductor screen adopts silver-plated lenticular wire internal layer and the outer double braid of silver-plated single line, to improve the shielding properties of cable.
The utility model expanded microporous polytetra fluoroethylene-EPTEE soft radio frequency cable that insulate, described inner wire heart yearn adopt 7 or 19 silver-coated copper wires stranded, guarantee the flexibility of cable.
The utility model expanded microporous polytetra fluoroethylene-EPTEE soft radio frequency cable that insulate, the outer polyurethane material that adopts of described sheath.
The utility model selects for use these materials can guarantee that cable has lower loss, suitable flexibility and the characteristic of wide working temperature.
The utility model has adopted some special material and processing modes, thereby this cable has low-loss, broadband, low standing wave, characteristics such as high shielding than radio frequency cable of the same type.Be usually used in high-frequency range: can reach 18G～26G.Transmission attenuation is little, the cable softness.
The utility model decay nominal value such as following table:
| F(GHz) | 1 | 3 | 6 | 10 | 16 | 18 | 26 |
| (αdB/m) | 0.39 | 0.74 | 1.08 | 1.43 | 1.80 | 1.99 | 2.48 |

| 0.18 | 0.33 | 0.50 | 0.68 | 0.95 |
When cable was pressed the regulation test of 4.7.10 among the GJB973A-2004, the return loss of cable (specimen length is 6m) was not less than following table institute indicating value:
| Frequency range (GHz) | 0.05～4 | 4～8 | 8～18 | 18～26 |
| Return loss value (dB) | 17.7 | 15.6 | 14.0 | 12.7 |
