Description

A kind of double layer screen tape cable

Technical field

The utility model relates to field of cable technology more particularly to a kind of double layer screen tape cables.

Background technique

Anti- signal interference signal control line need to surround the upper one layer aluminium foil strip for being coated with aluminium outside signal wire, anti-interference to increase Ability is needed sometimes outside around aluminium foil of double-baging, and conventional method uses wrapped on signal control line surface in two times around packet mode Aluminium foil, such production efficiency is one times low, meanwhile, band is covered with Shi Buquan, causes interference free performance poor.

Utility model content

The purpose of this utility model is to provide a kind of double layer screen tape cables, to solve the above technical problems.

The utility model uses following technical scheme to achieve the above object:

A kind of double layer screen tape cable, including conductor, inner insulating layer, tension strengthening core, filler, first layer band, Two layers of band, foaming PE layers, braiding layer, external insulation layer, the conductor are wrapped with inner insulating layer, and more are enclosed with inner insulating layer The conductor composition conducting wire around tension strengthening core be twisted, the multiple conducting wires are wrapped with first layer band and the second layer Band is equipped with filler between the first layer band and multiple conducting wires, the second layer belting layer is wrapped with braiding layer, institute It states braiding and is externally provided with external insulation layer layer by layer.

On that basis of the above technical scheme, the conductor is refined copper conductor, and the inner insulating layer and external insulation layer use chlorine Ethylene material, the filler are glass fiber, and the first layer band and second layer band are the aluminium foil strip for being coated with aluminium, are compiled Tissue layer is tinned copper wire braid shielded net.

Compared with prior art, the utility model has the advantage that the utility model using multiple conducting wires while being twisted When stranding, directlys adopt and drag the mode of packet by two layers of aluminium foil while rotation is wound on conductive line surfaces, stranding, the double-deck band are primary simultaneously It completes, due to stranding, first layer band, the synchronous progress of second layer band, realizes a hundred percent all standing, and production efficiency mentions One is risen, there is preferable shield effectiveness, prevent the communication apparatus of surrounding from receiving interference to a certain extent, PE foaming layer is played Protective effect strengthens cable isolation and vulnerability to jamming, and reduces material cost.

In figure: 1, conductor, 2, inner insulating layer, 3, tension strengthening core, 4, filler, 5, first layer band, 6, second layer packet Band, 7, PE layers of foaming, 8, braiding layer, 9, external insulation layer.

Specific embodiment

The utility model is further elaborated in the following with reference to the drawings and specific embodiments.

As shown in Figure 1-3, a kind of double layer screen tape cable, including conductor 1, inner insulating layer 2, tension strengthening core 3, filler 4, first layer band 5, second layer band 6, foaming PE layer 7, braiding layer 8, external insulation layer 9, the conductor 1 are wrapped with interior insulation Layer, the conducting wire that the more conductors 1 for being enclosed with inner insulating layer 2 form is twisted around tension strengthening core 3, outside the multiple conducting wires It is enclosed with first layer band 5 and second layer band 6, filler 4 is equipped between the first layer band 5 and multiple conducting wires, it is described 6 layers of second layer band are wrapped with braiding layer 8, and 8 layers of the braiding layer is externally provided with external insulation layer 9.

The first layer band 5 and second layer band 6 rotate cladding by the way of dragging packet centered on multiple conducting wires.

The conductor 1 is refined copper conductor, and the inner insulating layer 2 and external insulation layer 9 use vinyl chloride material, the filler 4 be glass fiber, and the first layer band 5 and second layer band 6 are the aluminium foil strip for being coated with aluminium, and braiding layer 8 is tinned copper wire Braid shielded net.

The utility model using multiple conducting wires simultaneously twisted synthesizing cable when, directly adopt drag the mode of packet by two layers of aluminium foil simultaneously Rotation is wound on conductive line surfaces, and stranding, the double-deck band are primary simultaneously to be completed, since stranding, first layer band, second layer band are synchronous It carries out, realizes a hundred percent all standing, and improving productivity one, there is preferable shield effectiveness, to a certain extent Prevent the communication apparatus of surrounding from receiving interference, PE foaming layer plays a protective role, and strengthens cable isolation and vulnerability to jamming, and drop Low material cost.

The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired Change, replacement and variant is still fallen within the protection scope of the utility model.
