The pcs signal connecting line of existing common household electrical appliance internal signal device or building interior is usually by conductive copper Core and insulating layer composition.It is well known that the electric wire of this structure can generate electromagenetic wave radiation, while itself when being powered itself Also it can be interfered by the electromagnetic wave of other electronic building bricks, so that often influencing electric appliance just because of Electromagnetic Interference in use Often work.I.e. its anti-interference is poor, is easy to be influenced by the external world, influences the transmission of signal.

Utility model content

In view of the above deficiencies, a kind of the purpose of the utility model is to provide shield effectiveness good, strong interference immunity, and make With the feedback transmission band shielded cable that the service life is long.

To achieve the above object, technical solution provided by the utility model is: a kind of feedback transmission band shielded cable, It the core wire that is mutually twisted centered on the center conductor including the eccentric conducting wires of one center conductor and six strands and successively coats PET belting layer, tinned copper braid, aluminium foil layer and PVC serving on the core wire；The center conductor includes by more copper The center PE insulating layer that line is twisted center conductor and is coated on the center conductor, the bias conducting wire includes by more copper The eccentric PE insulating layer that line is twisted eccentric conductor and is coated on the bias conductor, the center PE insulating layer and bias PE The thickness of insulating layer is 1.3~1.5mm.

As a kind of improvement of the utility model, the PET belting layer with a thickness of 0.3~0.4mm.

As a kind of improvement of the utility model, the tinned copper braid with a thickness of 0.2~0.3mm.

As a kind of improvement of the utility model, the aluminium foil layer with a thickness of 0.1~0.2mm.

As a kind of improvement of the utility model, the outer surface of the PVC serving is equipped with to be extended along its axial direction Raised line, the raised line are embedded with ground line.One end of ground line is connected with tinned copper braid, other end ground connection can more mention Rise shield effectiveness, strong antijamming capability.

The utility model has the following beneficial effects: the utility model smart structural design, rationally, be successively coated on core wire PET belting layer, tinned copper braid, aluminium foil layer and PVC serving, are isolated by tinned copper braid and aluminium foil layer, screen It is good to cover effect, effectively promotes anti-radiation and anti-interference ability, reduces external interference, passes through PET belting layer and PVC serving centering Heart conducting wire and eccentric conducting wire carry out cladding protection, have preferable oil resistivity, chemical resistance and the performances such as wear-resisting, tear-resistant, greatly The big service life for extending cable, while the outer PE material that is all made of of center conductor and eccentric conducting wire is made, chemical stability Good, electrical insulating property is excellent, further promotes the comprehensive performance of cable, applied widely.

With reference to the accompanying drawing with embodiment, the present invention will be further described.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Referring to Fig. 1, a kind of feedback transmission band shielded cable provided in this embodiment comprising one center conductor 1 and six The eccentric core wire being mutually twisted centered on the center conductor 1 of conducting wire 2 of stock and the PET band being successively coated on the core wire Layer 3, tinned copper braid 4, aluminium foil layer 5 and PVC serving 6；PET belting layer 3, tin-coated copper braiding are successively coated on core wire Layer 4, aluminium foil layer 5 and PVC serving 6, are isolated, shield effectiveness is good, effectively mentions by tinned copper braid 4 and aluminium foil layer 5 Anti-radiation and anti-interference ability is risen, external interference is reduced, by PET belting layer 3 and PVC serving 6 to center conductor 1 and bias Conducting wire 2 carries out cladding protection, has preferable oil resistivity, chemical resistance and the performances such as wear-resisting, tear-resistant, greatly prolongs cable Service life.

The center conductor 1 includes the center for being twisted center conductor by more copper wire and being coated on the center conductor PE insulating layer, the bias conducting wire 2 include being twisted eccentric conductor by more copper wire and being coated on inclined on the bias conductor The thickness of heart PE insulating layer, the center PE insulating layer and bias PE insulating layer is 1.3~1.5mm.Center PE insulating layer and Eccentric PE insulating layer is all made of PE material and is made, and chemical stability is good, and electrical insulating property is excellent, further promotes the comprehensive of cable Can, it is applied widely.

Preferably, the PET belting layer 3 with a thickness of 0.3~0.4mm, preferably 0.36 mm.The tin-coated copper braiding Layer 4 with a thickness of 0.2~0.3mm, preferably 0.25mm.The aluminium foil layer 5 with a thickness of 0.1~0.2mm, preferably 0.15mm。
