Description

A kind of computer flexible shielded cable

Technical field

This utility model relates to field of cables, particularly relates to a kind of computer flexible shielded cable.

Background technology

At present, development along with science and technology, no matter it is industry or the daily life of the mankind, all develop towards electrified direction, cable is then in industry and power domain, its status is also gradually rising, the existing construction of cable includes many conductors, is coated on several parts such as the insulating barrier outside each conductor, braid and sheath, and existing cable bending resistance is not as, in bending situation frequently, cable is easy to situation fracture occur, brings very big inconvenience to the use of the maintenance of staff and user.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of computer flexible shielded cable.

This utility model takes techniques below scheme to realize: a kind of computer flexible shielded cable, it includes cable body, and described cable body includes conductor, insulating barrier, screen layer and oversheath, and described cable body is internally provided with multiple conductor；Described conductor outer wrapping one layer protection set；Described protection set and conductor collectively form cable core；Described cable body is internally provided with multiple cable core；Described cable body center is provided with polyethylene tube；One layer insulating is set outside described cable core；One layer of screen layer is extruded outside described insulating barrier；One layer of steel-tape armouring layer is extruded outside described screen layer；One layer of proof copper-wire braided layer is extruded outside described steel-tape armouring layer；One layer of inner sheath is extruded outside described proof copper-wire braided layer；One layer of oversheath is extruded outside described inner sheath.

Above-mentioned a kind of computer flexible shielded cable, described conductor is that naked copper or tin plated materials and carbon fibre material are stranded to be formed.

Above-mentioned a kind of computer flexible shielded cable, between described insulating barrier, cable core and polyethylene tube, gap portion is provided with packed layer.

Above-mentioned a kind of computer flexible shielded cable, described steel-tape armouring layer is internally provided with many carbon fiber composite core rods.

Above-mentioned a kind of computer flexible shielded cable, described proof copper-wire braided layer adopts copper free wire braiding to form.

Above-mentioned a kind of computer flexible shielded cable, described oversheath adopts fluorosioloxane rubber to make.

This utility model has the advantages that this utility model cable has the advantages such as reasonable in design, bend resistance performance be good and easy to use in sum, described oversheath adopts fluorosioloxane rubber to make, this kind of material is based on silicon-fluorine polymer thing, there is resistance to polarity and the oil resistance of excellence, and can when high temperature and low temperature life-time service, there is the advantages such as corrosion-resistant, weather-proof and excellent electrical insulating property simultaneously, and can electromagnetism interference.

Detailed description of the invention

As it is shown in figure 1, a kind of computer flexible shielded cable, it includes cable body 1, and described cable body 1 includes conductor 2, insulating barrier 6, screen layer 7 and oversheath 12, and described cable body 1 is internally provided with multiple conductor 2；Described conductor 2 outer wrapping one layer protection set 3；Described protection set 3 and conductor 2 collectively form cable core；Described cable body 1 is internally provided with multiple cable core；Described cable body 1 center is provided with polyethylene tube 5；One layer insulating 6 is set outside described cable core；One layer of screen layer 7 is extruded outside described insulating barrier 6；One layer of steel-tape armouring layer 8 is extruded outside described screen layer 7；One layer of proof copper-wire braided layer 10 is extruded outside described steel-tape armouring layer 8；One layer of inner sheath 11 is extruded outside described proof copper-wire braided layer 10；One layer of oversheath is extruded outside described inner sheath 11.

Described conductor 2 is for naked copper or tin plated materials and carbon fibre material is stranded forms, and is possible not only to so that conductor 2 that to transmit signal more stable, and is not easy to fracture, and also allows for the maintenance of later stage workman；Described polyethylene tube 5 increases the resistance to tension of conductor 2, it is to avoid conductor 2, because being there is the situation of fracture by external force, expands the use scope of cable；Described steel-tape armouring layer 8 can play good magnetic conduction effect, it is ensured that cable also can be properly functioning under noiseless environment, it is ensured that the safe operation of equipment；Described carbon fiber composite core rod 9 further enhances the structural strength of cable body 1, makes cable also can use for a long time under high temperature and high pressure environment, extends the service life of cable body 1；Described proof copper-wire braided layer 10 adopts copper free wire braiding to form, and not only increases the electromagnetic shielding capability of cable, simultaneously without influence on the pliability of cable；Described oversheath 12 adopts fluorosioloxane rubber to make, this kind of material is based on silicon-fluorine polymer thing, has resistance to polarity and an oil resistance of excellence, and can when high temperature and low temperature life-time service, there is the advantages such as corrosion-resistant, weather-proof and excellent electrical insulating property simultaneously, and can electromagnetism interference.

The above is embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model application range, feature and principle change or modify, and are all included in this utility model patent claim.
