Description

A kind of double layer screen armouring insulated cable

Technical field

The utility model is related to electric wire fields, more specifically more particularly to a kind of double layer screen armouring insulated electro Cable.

Background technology

With the development of science and technology various instruments are all producing, what is produced therewith is exactly more and more electricity Cable, and what cable was usually all twisted by multiple conducting wires, mutually insulated between each wire, and also need in different field to electricity The requirement of cable is also relatively different, and existing cable on shielding outer signals and influences also to be designed not reasonable, makes existing Cable cannot play shielding outer signals effect, it is easy to be interfered by outer signals, cause it to transmit signal performance difference etc. and lack Point does not meet demand of the existing people to cable.

Utility model content

The utility model to solve the above-mentioned problems, provides a kind of double layer screen armouring insulated cable, technical solution is such as Under：

A kind of double layer screen armouring insulated cable, including insulating layer and core wire, the insulating layer wrap up core wire, the insulation Layer is outer to be wrapped up by first screen layer, and the first screen layer is outer to be wrapped up by armor, between the first screen layer and armor Gap portion is provided with filler, and secondary shielding layer, twining package tape and oversheath are enclosed with successively outside the armor.

Preferably, the twining package tape uses aluminium-plastic tape, and winding is wrapped in outside secondary shielding layer.

Preferably, the first screen layer and secondary shielding layer are all made of compound copper-plastics band material.

Preferably, the filler uses high-temperature insulation material.

Preferably, the oversheath is made of PVC material.

Preferably, the insulating layer is made of PVC material.

Compared with prior art, the beneficial effects of the utility model are：The utility model is reasonable for structure, anti-tampering and use The features such as long lifespan, realizes jamproof effect to cable by using two layers of shielded layer, and can be prevented by armor It presses, pound, racking short circuit caused by damage core after cable sheath.

Further, first screen layer and secondary shielding layer are all made of compound copper-plastics band material, can effectively reduce outer bound pair The interference of cable keeps transmission quality and transmission signal more stable.

Further, the filler uses high-temperature insulation material, and cable is made persistently to be kept in the case of flame calcination Good insulation performance can also work normally to realize that cable is under the calcination of flame.

Description of the drawings

It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment The attached drawing used is briefly described：

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

Including：It is core wire 10, insulating layer 11, first screen layer 12, filler 13, armor 14, secondary shielding layer 15, wrapped Band 16, oversheath 17.

Specific implementation mode

With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work The every other embodiment obtained, belongs to the scope of protection of the utility model.

The utility model embodiment is described in further detail below in conjunction with attached drawing, it is as follows in detail：

A kind of double layer screen armouring insulated cable, including insulating layer 11 and core wire 10, insulating layer 11 wrap up core wire 10, insulation Layer 11 is outer to be wrapped up by first screen layer 12, and first screen layer 12 is outer to be wrapped up by armor 14, first screen layer 12 and armor 14 Between gap portion be provided with filler 13, secondary shielding layer 15, twining package tape 16 and outer shield are enclosed with outside armor 14 successively Set 17.

In the present invention, twining package tape 16 uses aluminium-plastic tape, and winding is wrapped in outside secondary shielding layer 15.

Oversheath 17 is made of PVC material.

Insulating layer 11 is made of PVC material.

By taking theory structure combination above structure as an example, increase the purpose of armor 14 on cable in addition to enhancing tension is strong Degree, compression strength are outer to prolong the service life, more important is the anti-interference for improving cable by shielding protection, and this practicality It is novel again by increasing by two layers of shielded layer 15, so that the utility model is played better effect to external interference, and pass through Armor 14 can prevent from pressing, pound, rack short circuit caused by damage core after cable sheath.

Further, first screen layer 12 and secondary shielding layer 15 are all made of compound copper-plastics band material, can effectively reduce outer The interference of bound pair cable keeps transmission quality and transmission signal more stable.

Further, the filler 13 uses high-temperature insulation material, and cable is made persistently to be protected in the case of flame calcination Good insulation performance is held, can also be worked normally to realize that cable is under the calcination of flame.
