Electric wire is in order to transmit electricity (magnetic) energy, and information and the wire product realizing electromagnetic energy conversion, the electric wire of broad sense is also referred to simply as cable, and the cable of narrow sense refers to insulated cable, and it may be defined as: the aggregation being made up of following part；One or more insulated wire cores, and the clad that each of which is likely to be of, total protective layer and outer jacket, cable also can have the additional conductor not having insulation.In order to transmit electricity (magnetic) energy, information and the wire product realizing electromagnetic energy conversion.The electric wire of broad sense is also referred to simply as cable, and the cable of narrow sense refers to insulated cable.It may be defined as, the aggregation being made up of following part: one or more insulated wire cores, and the clad that each of which is likely to be of, total protective layer and outer jacket, and cable also can have the additional conductor not having insulation.Existing cable in use between cable can be caused to be damaged by rolling for a long time.
Such as, Chinese patent literature discloses a kind of cable [application number: 201120191567.3], including some cables core, PP rope packed layer, dacron thread braid and oversheath, cable core includes some conductors, colour band and polyolefin inner sheath the most from inside to outside, is between the conductor in described cable core and colour band and is equipped with between described dacron thread braid and oversheath to be woven, by compound copper-plastics band, the wire sheathing made.This utility model is by arranging wire sheathing in cable core, and this wire sheathing has functioned well as the shield effectiveness between cable core, and anti-interference raising i.e. decreases crosstalk；And between dacron thread braid and oversheath, it is also provided with identical wire sheathing, the most effectively increase anti-external disturbance performance.
Although such scheme has can protect core, but it is not reasonable to remain design, there is crushing resistance poor, is easily damaged, and safety can not get the technical problems such as guarantee.
Summary of the invention
The purpose of this utility model is for the problems referred to above, it is provided that a kind of reasonable in design, is hardly damaged, safe and reliable pressure network cable.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this pressure network cable, it is characterized in that, including three of the wires, it is provided with in three of the wires periphery and can be wound around the first of three of the wires and tighten layer, tighten layer periphery first to be provided with second and tighten layer, tighten layer and second first to tighten there is between layer the first packed layer, it is equipped with ground wire on the first described packed layer, tighten layer periphery second and be provided with oversheath, described second is tightened and is provided with resistance to compression assembly between layer and oversheath, described resistance to compression assembly include four axially arranged and be uniformly distributed the pressure resistance column that cross section is rounded in a circumferential direction, it is provided with some along pressure resistance column axial distribution and the pressure-proof spring of horizontally set between two pressure resistance columns of arbitrary neighborhood.
In above-mentioned pressure network cable, described pressure-proof spring one end is fixed on a pressure resistance column, and the other end is fixed on another root pressure resistance column.
In above-mentioned pressure network cable, each wire includes some cores, is arranged with Wire sheath in some core peripheries, and described ground wire is made up of the most metal-cored.
In above-mentioned pressure network cable, described resistance to compression assembly and second is tightened and is provided with corrugated tube between layer, has the second packed layer between described corrugated tube and oversheath.
In above-mentioned pressure network cable, the first described packed layer and the second packed layer are polytetrafluoroethylmaterial material.
In above-mentioned pressure network cable, described first is tightened layer and second and tightens layer and be mica material and make.
Compared with prior art, the advantage of this pressure network cable is: reasonable in design, is hardly damaged, and safe and reliable, sound construction is long for service life, can effectively resist ambient pressure.
