Utility model content

In view of the above, the purpose of this utility model is to provide a kind of insulation control cable, improves cable shield performance, strengthens its antijamming capability.

A kind of insulation control cable, comprise its inner some cable cores arranged, described cable core comprises its inner setting by the conductor of many proof copper-wire braideds and insulating barrier conductor being rolled into circular cross-section, circular cross-section is rolled into by arranging packing material by lapping layer between some cable cores, aluminium THIN COMPOSITE film strips, proof copper-wire braided layer, restrictive coating is disposed with outside described lapping layer, wherein said lapping layer adopts PET film, the copper wire band that described proof copper-wire braided layer is made up of copper wire adopts compartment braiding to form, and described restrictive coating adopts crosslinked polyethylene to make.

A kind of insulation control cable that the utility model provides, preferably, described copper wire adopts tinned copper wire, and the diameter of copper wire is 1.03mm, and on each copper wire band, the radical of copper wire is 60.

A kind of insulation control cable that the utility model provides, preferably, the thickness of described insulating barrier is 4.5mm.

A kind of insulation control cable that the utility model provides, preferably, the thickness of described sheath is 0.68mm to 1.20mm.

Preferential and beneficial effect of the present utility model is: a kind of insulation control cable that the utility model provides, a PET film is set up in aluminium THIN COMPOSITE film strips inside by insulation control cable, make the connection between cable core tightr, and play certain cushioning effect, prevent aluminium THIN COMPOSITE film strips from scratching or incised wound cable core insulating barrier, and it is wrapped by the braiding of copper wire band in aluminium THIN COMPOSITE film strips, and employing is compartment braiding, raw material are saved to a certain extent, the antijamming capability providing cable is isolated by the bilayer of aluminium THIN COMPOSITE film strips and copper wire band braid.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, preferred implementation of the present utility model is just preferably described, wherein,

The schematic diagram of a kind of insulation control cable that Fig. 1 provides for the utility model;

The cross-sectional view of a kind of insulation control cable that Fig. 2 provides for the utility model.

Embodiment

Referring to figs. 1 through Fig. 2, a kind of insulation control cable embodiment of the utility model is described further.

A kind of insulation control cable in Fig. 1 and Fig. 2, comprise its inner some cable cores 1 arranged, described cable core 1 comprises its inner setting by the conductor 11 of many proof copper-wire braideds and the insulating barrier 12 conductor 11 being rolled into circular cross-section, and described cable core 1 also can set up internal shield 13 between insulating barrier 12 and conductor 11, the screening ability of cable can be improved like this, circular cross-section is rolled into by arranging packing material 2 by lapping layer 3 between some cable cores 1, aluminium THIN COMPOSITE film strips 4 is disposed with outside described lapping layer 3, proof copper-wire braided layer 5, restrictive coating 6, wherein said lapping layer 3 adopts PET film, and described PET film adopts transparent membrane.The copper wire band 51 that described proof copper-wire braided layer 5 is made up of copper wire fits tightly and adopts compartment braiding to form in aluminium THIN COMPOSITE film strips 4, every two adjacent and spacing L between the copper wire band 51 that lapping direction is identical is 1/4 to 1/3 of copper wire band 51 width D, the intersection point of every four crossing copper wire bands 51 forms a rhombus, and described restrictive coating 6 adopts crosslinked polyethylene to make.Described copper wire adopts tinned copper wire, and the diameter control of copper wire is at 0.98mm to 1.05mm, and preferably, the diameter of copper wire is 1.03mm.On each copper wire band 51, the radical of copper wire is 60 simultaneously.

The thickness of described insulating barrier 12 is 4.5mm.The thickness of described sheath 6 is 0.68mm to 1.20mm.

Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
