Description

Double-layer shielded computer cable

Technical field

The utility model is related to technical field of electric wires and cables, and in particular to a kind of double-layer shielded computer cable.

Background technology

Although a wires and cables industry simply supporting industry, in occupation of the output value of Chinese electrician trade 1/4.Its product Huge number, application is quite varied, is related to the industries such as electric power, building, communication, manufacture, each portion with national economy Door is all closely related.Electric wire is also known as " artery " and " nerve " of national economy, is conveying electric energy, transmission information and system Various motors, instrument, instrument are made, the indispensable basic equipment of electromagnetic energy conversion institute is realized, is following electrified, information Change necessary basic product in society.

The pcs signal connecting line of existing conventional household electrical appliance internal signal device or building interior is generally by conductive copper Core and insulating barrier composition.It is well known that the electric wire of this structure can produce electromagenetic wave radiation in itself when being powered, while itself Also it can be disturbed by the electromagnetic wave of other electronic building bricks, so that often influenceing electrical equipment because of Electromagnetic Interference just in use Often work.I.e. its anti-interference is poor, easily by ectocine, has influence on the transmission of signal.

Utility model content

For above-mentioned deficiency, the purpose of this utility model be there is provided a kind of smart structural design, rationally, with dual Shield effectiveness, the good double-layer shielded computer cable of antijamming capability.

To achieve the above object, technical scheme provided by the utility model is：A kind of double-layer shielded computer cable, it includes By seven strands of wires and the stranded cored wire of one ground wire and the aluminium foil wheat being coated on successively on the cored wire are drawn, tinned copper wire is shielded Stratum reticulare and PVC servings；The tinned copper wire shields 0.10~0.14mm of thickness of stratum reticulare；The wire includes many tin-coated coppers The stranded thickness for forming tegillum in tegillum in the PVC of conductor and cladding on the conductor, the PVC of line is 1.2~1.4mm, institute The thickness for stating PVC servings is 6.3~6.7mm, and the thickness that the aluminium foil wheat is drawn is 0.22~0.27mm.

As a kind of improvement of the present utility model, the ground wire is tin annealed copper wire.

The beneficial effects of the utility model are：The utility model smart structural design, rationally, be coated with successively on cored wire The drawing of aluminium foil wheat and tinned copper wire shield stratum reticulare, form double-layer shielding structure, and shield effectiveness is good, effectively lift radioresistance and anti-interference Ability, reduces external interference, and then the quality of signal transmission is effectively ensured；It is simultaneously stranded in cored wire to have one ground wire, by connecing Ground causes screening energy further to be lifted, strong antijamming capability, is particularly suitable for use in pcs signal connection use；In use, PVC servings It can effectively protect and isolate cored wire, greatly prolong the service life of electric wire, dielectric properties are excellent, and pliability is good.

Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

A kind of double-layer shielded computer cable provided referring to Fig. 1, the present embodiment, it is included by seven strands of wires 1 and one ground wire 5 Stranded cored wire and the aluminium foil wheat being coated on successively on the cored wire draw 2, tinned copper wire shielding stratum reticulare 3 and PVC servings 4； Preferably, the ground wire 5 is tin annealed copper wire, inoxidizability is strong.It is coated with aluminium foil wheat successively on cored wire and draws 2 and tinned copper wire Stratum reticulare 3 is shielded, double-layer shielding structure is formed, shield effectiveness is good, effectively lifting radioresistance and antijamming capability, is reduced extraneous dry Disturb, and then the quality of signal transmission is effectively ensured；It is simultaneously stranded in cored wire to have one ground wire 5, by ground connection screening energy is entered One step is lifted, and strong antijamming capability is particularly suitable for use in pcs signal connection

The tinned copper wire shields the 0.10~0.14mm of thickness, preferably 0.12mm of stratum reticulare；The wire 1 includes many Tinned wird is stranded into tegillum in conductor and cladding PVC on the conductor, in the PVC thickness of tegillum for 1.2~ 1.4mm, preferably 0.3mm, the aluminium foil wheat draw 2 thickness for 0.22~0.27mm, preferably 0.25mm.The outer quilts of the PVC The thickness of layer 4 is 6.3~6.7mm, preferably 6.5mm, in use, PVC servings 4 can effectively be protected and isolate cored wire, significantly The service life of extending wire, dielectric properties are excellent, and pliability is good

Preferably, being provided with multiple annular projections on the outer surface of tegillum also in PVC, effectively strengthen frictional force, reduce and shake It is dynamic, it more can guarantee that the quality of signal transmission；Thickness is also increased simultaneously, lifts abrasion resistant effect.

The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model Constitute any limitation.As described in the utility model above-described embodiment, using other obtained from same or similar structure The electric wire of structure, in the utility model protection domain.
