Description

A kind of shield type holding wire

Technical field

The utility model relates to signal data transmission technique field, particularly relates to a kind of shield type holding wire.

Background technology

Traditional audio signal wire, generally be made up of two bundle conductors and the PVC material layer be coated on outside two bundle conductors, bundle conductor generally adopts copper wire to make, and the audio signal wire of this structure exists shielding properties difference, and the transmission of audio signal such as to be easily interfered at the problem.For blocking the harassing and wrecking in external interference source in transfer of data, or prevent other equipment of electromagnetic interference of signal transmission, signal cable generally adopts the measures such as aluminium foil, aluminium-plastic tape, metal net to shield electromagnetic interference.But, along with the development of mechanics of communication, the speed goes of transfer of data is fast, the frequency of transmission is more and more higher, electromagnetic amount of radiation also increases thereupon, and at high frequency, ultra-high-frequency data transmission field, traditional shielding material such as aluminium foil, aluminium-plastic tape, metal net etc. have not reached desirable shield effectiveness, the requirement of Electro Magnetic Compatibility cannot be met, urgently improve.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind ofly has good shielding properties, safe and reliable shield type holding wire.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of shield type holding wire, comprise the wire stylet, packed layer, external insulation layer, outer shielding layer and the sheath that set gradually from inside to outside, described sheath is coated on the outside of described outer shielding layer, described outer shielding layer is coated on the outside of described external insulation layer, described wire stylet is positioned at described external insulation layer, and described packed layer is arranged on the gap between described wire stylet and described external insulation layer; The inner insulating layer that described wire stylet comprises conductor, is coated on the internal shield outside described conductor and is coated on outside described internal shield, described wire stylet can be provided with one or more; Described external insulation layer adopts cotton paper, cotton yarn or polytetrafluoroethylmaterial material to make; Described outer shielding layer comprises tincopper fuse wire braided armor and copper foil wire braid, and described copper foil wire braid is coated on the outside of described tincopper fuse wire braided armor, to strengthen tensile property, strengthens shielding properties simultaneously, can also reduce costs and lower molding difficulty.

Preferably, the copper conductor that described conductor adopts outside to be provided with silver coating is made.Preferably, described internal shield adopts tinned copper wire braiding to form, and in order to strengthen inner shield, reduces by two bundle conductors and produces interference when transmission of audio signal.Preferably, described inner insulating layer adopts cotton paper, cotton yarn or polytetrafluoroethylmaterial material to make.

Preferably, be provided with between described tincopper fuse wire braided armor and described copper foil wire braid and inhale ripple layer, strengthen the shielding properties of holding wire further.

Preferably, described packed layer is made up of cotton yarn or Kevlar fabric, in order to strengthen tensile property and the structural strength of holding wire entirety.

Preferably, described sheath adopts polytetrafluoroethylmaterial material to make, to strengthen integrally-built protection.Polytetrafluoroethylene is a kind of Prof. Du Yucang macromolecular material employing fluorine atom and replace all hydrogen atoms in polyethylene, its chemical stability and good insulating, there is the feature of antiacid alkali resistant, anti-various organic solvent, also have resistant to elevated temperatures feature and extremely low coefficient of friction, be the ideal material of pipeline simultaneously.

Based on technique scheme, the beneficial effects of the utility model are: the utility model adopts the screen of multilayer coating structure outside conductor, can improve the laser propagation effect of signal, have good shield effectiveness, make the signal of transmission purer; Adopt the multiple protective layer such as packed layer, insulating barrier, sheath, improve the performances such as high temperature resistant, the anticorrosion of holding wire and stretch-proof, effectively extend its useful life, strengthen the reliability of its use procedure.
