Description

Resistance to compression cable

Technical field

This utility model belongs to communication accessory technical field, especially relates to a kind of resistance to compression line Cable.

Background technology

Electric wire is in order to transmit electricity (magnetic) energy, information and the line realizing electromagnetic energy conversion Material product, the electric wire of broad sense is also referred to simply as cable, and the cable of narrow sense refers to insulated electro Cable, it may be defined as: the aggregation being made up of following part；One or more covered wire Core, and the clad that each of which is likely to be of, total protective layer and outer jacket, cable Also can there is the additional conductor not having insulation.In order to transmit electricity (magnetic) energy, information and reality The wire product of existing electromagnetic energy conversion.The electric wire of broad sense is also referred to simply as cable, narrow sense Cable refer 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, always protect Layer and outer jacket, cable also can have the additional conductor not having insulation.Existing cable exists The use time can cause cable to be damaged by rolling for a long time.

Such as, Chinese patent literature disclose a kind of network cable [application number: 201420240509.9], including: four strands of twisted-pair feeders, it is arranged on outside four strands of twisted-pair feeders Metal tape lapped shielding layer and be arranged on the oversheath outside described metal tape lapped shielding layer Layer, is provided with flame resistant filler layer between described four strands of twisted-pair feeders and metal lapped shielding layer, Described flame resistant filler layer is provided with four tension ropes.

Although such scheme has can protect core, but remain design not Rationally, there is crushing resistance poor, be easily damaged, be also easy to be baited by animals such as mouse, Cable damage, safety is caused to 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, no Fragile, safe and reliable resistance to compression cable.

For reaching above-mentioned purpose, this utility model have employed following technical proposal: this resistance to compression Cable, the wire turned to including some cores, described wire periphery is provided with interior insulation Layer, it is characterised in that be cased with pressure-resistant framework, described pressure-resistant framework on described inner insulating layer The most uniform by three including internal ring and outer shroud, described internal ring and outer shroud The supporter of distribution is connected, and three supporters are by the circular gap between internal ring and outer shroud It is separated into three chambers, in each chamber, is provided with air cushion, described air cushion maximum volume It is slightly less than chamber volume, places outside described pressure-resistant framework to be provided with and prevent baiting structure, described Prevent that baiting structure peripheral is provided with external insulation layer.

In above-mentioned resistance to compression cable, described anti-structure of baiting includes being fixed on outside outer shroud Place some circumferences be uniformly distributed and the most equally distributed first anti-bait tooth, arbitrarily Adjacent two first anti-baiting are provided with between tooth that second matched with backlash is anti-baits tooth, Described second prevents that baiting tooth is fixed on inside external insulation layer.

In above-mentioned resistance to compression cable, between described inner insulating layer and internal ring, there is annular Fire prevention cushion pad.

In above-mentioned resistance to compression cable, described annular fire prevention cushion pad includes foamed plastic Layer, has mica layer inside described foamed plastic layer.

In above-mentioned resistance to compression cable, described internal ring, outer shroud and supporter are connected as a single entity Formula structure.

In above-mentioned resistance to compression cable, described pressure-resistant framework is that PA material is made.

Compared with prior art, the advantage of this resistance to compression cable is: reasonable in design, no Fragile, safe and reliable, can bait by the toy such as effective anti-ageing Mus；Sound construction, Crushing resistance is good, can effectively buffer rolling of the external world, ensures that communication is smooth and easy；Even if running into Fire also can effectively prevent core from damaging.

Accompanying drawing explanation

Fig. 1 is the structural representation that this utility model provides.

In figure, wire 1, inner insulating layer 2, pressure-resistant framework 3, internal ring 31, outer shroud 32, The anti-tooth 41, second of baiting of supporter 33, chamber 34, air cushion 35, first is prevented baiting tooth 42, fire prevention cushion pad 6, foamed plastic layer 61, mica layer 62.

Detailed description of the invention

As it is shown in figure 1, this resistance to compression cable, the wire 1 turned to including some cores, lead Line 1 periphery is provided with inner insulating layer 2, it is characterised in that be cased with resistance to compression on inner insulating layer 2 Frame 3, pressure-resistant framework 3 includes that internal ring 31 and outer shroud 32, internal ring 31 and outer shroud 32 are by three Individual the most equally distributed supporter 33 is connected, and three supporters 33 will Circular gap between internal ring 31 and outer shroud 32 is separated into three chambers 34, in each chamber Being provided with air cushion 35 in room 34, air cushion 35 maximum volume is slightly less than chamber 34 volume, anti- Place outside pressure rack 3 to be provided with and prevent baiting structure 4, prevent that baiting structure 4 periphery is provided with external insulation Layer 5.Reasonable in design, it is hardly damaged, safe and reliable, can the petty action such as effective anti-ageing Mus Thing is baited；Sound construction, crushing resistance is good, can effectively buffer rolling of the external world, ensures Communication is smooth and easy；Also can effectively prevent core from damaging even if running into fire.

In particular, anti-structure 4 of baiting includes being fixed on outside outer shroud 32 and places some weeks To being uniformly distributed and the most equally distributed first anti-baiting tooth 41, arbitrary neighborhood two First anti-baiting is provided with between tooth 41 that second matched with backlash is anti-baits tooth 42, the Two prevent that baiting tooth 42 is fixed on inside external insulation layer 5, inner insulating layer 2 and internal ring 31 Between have annular fire prevention cushion pad 6, annular fire prevention cushion pad 6 include foamed plastic layer 61, there is inside foamed plastic layer 61 mica layer 62；Internal ring 31, outer shroud 32 and support Body 33 is connected as a single entity structure；Pressure-resistant framework 3 is made for PA material.

Specific embodiment described herein is only for example to this utility model spirit Explanation.This utility model person of ordinary skill in the field can be to described concrete Embodiment is made various amendment or supplements or use similar mode to substitute, but not Spirit of the present utility model can be deviateed or surmount model defined in appended claims Enclose.

Although the most more use wire 1, inner insulating layer 2, pressure-resistant framework 3, internal ring 31, Outer shroud 32, supporter 33, chamber 34, air cushion 35, first are prevented baiting tooth 41, second Prevent baiting the term such as tooth 42, fire prevention cushion pad 6, foamed plastic layer 61, mica layer 62, But it is not precluded from using the probability of other term.These terms are used to be only used to more Describe and explain essence of the present utility model easily；It is construed as any attached The restriction added is all contrary with this utility model spirit.
