Description
Technical field
The invention belongs to technical field of cables, especially relate to a kind of pressure network cable.
Background technology
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 can cause cable to be damaged by rolling for a long time in use.
Such as, Chinese patent literature discloses a kind of cable [application number: 201520164861.3], 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.The present invention 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 poor to remain crushing resistance, is easily damaged, and safety can not get the technical problems such as guarantee.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of reasonable in design, be hardly damaged, safe and reliable pressure network cable.
For reaching above-mentioned purpose, present invention employs following technical proposal: this durable type cable, it is characterized in that, including some have lead core sheath lead core, it is arranged with and can wrap up some the first of cores of leading leading core periphery and tighten layer, tighten layer periphery first to be provided with second and tighten layer, tighten layer and second first to tighten and between layer, be provided with ground wire, described second is tightened layer periphery and is provided with surge layer, it is provided with oversheath in surge layer periphery, it is provided with some along the axial equally distributed resistance to compression assembly of cable between described surge layer and oversheath, described resistance to compression assembly includes that four circumferences are uniformly distributed and the pressure-proof spring of horizontally set, the end of two pressure-proof springs of arbitrary neighborhood is connected by contiguous block, described contiguous block outside is curved to adapt with oversheath.
In above-mentioned durable type cable, also having flexible packed layer between described oversheath and surge layer, described resistance to compression assembly is arranged in flexible packed layer.
In above-mentioned durable type cable, described oversheath is that PVC material is made, and described flexible packed layer is that polytetrafluoroethylmaterial material is made.
In above-mentioned durable type cable, described first tightens layer, and to be that mica tape is S-shaped be entwined, and it is integral type mica layer that described second tightens layer.
In above-mentioned durable type cable, described ground wire has ground wire protective layer.
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.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention provides.
In figure, lead core 1, lead core sheath 11, first tighten layer 2, second tighten layer 3, ground wire 4, surge layer 5, oversheath 6, resistance to compression assembly 7, pressure-proof spring 71, contiguous block 72, flexible packed layer 8.
Detailed description of the invention
As shown in Figure 1, this durable type cable, including some have lead core sheath 11 lead core 1, it is arranged with and can wrap up some the first of cores 1 of leading leading core 1 periphery and tighten layer 2, tighten layer 2 periphery first to be provided with second and tighten layer 3, tighten layer 2 and second first to tighten and between layer 3, be provided with ground wire 4, second tightens layer 3 periphery is provided with surge layer 5, it is provided with oversheath 6 in surge layer 5 periphery, it is provided with some along the axial equally distributed resistance to compression assembly 7 of cable between surge layer 5 and oversheath 6, resistance to compression assembly 7 includes that four circumferences are uniformly distributed and the pressure-proof spring 71 of horizontally set, the end of two pressure-proof springs 71 of arbitrary neighborhood is connected by contiguous block 72, contiguous block 72 outside is curved to adapt with oversheath 6.
Also having flexible packed layer 8 between oversheath 6 and surge layer 5, resistance to compression assembly 7 is arranged in flexible packed layer 8；Oversheath 6 is made for PVC material, and flexible packed layer 8 is made for polytetrafluoroethylmaterial material；First tightens layer 2 is entwined for mica tape is S-shaped, and second tightens layer 3 for integral type mica layer, and ground wire 4 has ground wire protective layer.
