Description

Compression-resistincable cable

Technical field

This utility model belongs to field of cable technology, especially relates to a kind of Compression-resistincable 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 Compression-resistincable cable [application number: 201320262997.9], including cable core and sheath, sheath is wrapped in cable core outer surface, protects Set is outside is surrounded by pressure-bearing set.At sheath outer cover harness resilient opening identification pressure-bearing set, Pressure-bearing set is by tuft support set and sheath flexibility fit, it is to avoid hard contact causes Power is transmitted, and pressure-bearing set is absorbed by the elastic shrinkage of self dissolves external force, and at all impact is not To cable core, thus avoid the external force impact to cable core, effectively protect cable.

Although such scheme has can protect core, but remain design not Rationally, being easily damaged, it is easy to suffered that toy baits damage, safety can not get protecting The technical problems such as barrier.

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, be energized the Compression-resistincable cable that can be protected.

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, sets outside described pressure-resistant framework The anti-of mouse bite preventing is had to bait screen layer, if described anti-baiting has on screen layer outer surface Dry circumference is uniformly distributed and axial equally distributed anti-tooth of baiting, and described anti-baits outside tooth Side is provided with metal screen layer, has external insulation layer outside described metal screen layer.

In above-mentioned Compression-resistincable cable, described air cushion volume is slightly less than the volume of chamber.

In above-mentioned Compression-resistincable cable, described internal ring, outer shroud and supporter are connected as a single entity Formula structure, and internal ring, outer shroud and supporter are for make for PA material.

In above-mentioned Compression-resistincable cable, described anti-bait hot melt on tooth and have rubber layer.

In above-mentioned Compression-resistincable cable, have between described described inner insulating layer and internal ring There is annular fire prevention cushion pad.

Compared with prior art, the advantage of this Compression-resistincable cable is: 1, reasonable in design, Being hardly damaged, safe and reliable, energising can be protected.2, structure is long for firm service life, Can effectively resist ambient pressure.3, shield effectiveness is good, can reduce the impact on toy.

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, Supporter 33, chamber 34, air cushion 35, anti-bait screen layer 4, anti-bait tooth 41, Metal screen layer 5, external insulation layer 6, rubber layer 41a, annular fire prevention cushion pad 7.

Detailed description of the invention

As it is shown in figure 1, this Compression-resistincable cable, the wire 1 turned to including some cores, lead Line 1 periphery is provided with inner insulating layer 2, and inner insulating layer 2 is cased with pressure-resistant framework 3, pressure-resistant framework 3 Including internal ring 31 and outer shroud 32, internal ring 31 and outer shroud 32 by three at circumferencial direction Upper equally distributed supporter 33 is connected, and three supporters 33 are by internal ring 31 and outer shroud Circular gap between 32 is separated into three chambers 34, is provided with gas in each chamber 34 Pad 35, is provided with the anti-of mouse bite preventing and baits screen layer 4 outside pressure-resistant framework 3, prevent baiting shielding There is on layer 4 outer surface some circumferences be uniformly distributed and axial equally distributed anti-bait tooth 41, anti-baiting is provided with metal screen layer 5 outside tooth 41, have outside metal screen layer 5 External insulation layer 6.Reasonable in design, it is hardly damaged, safe and reliable, energising can be protected； Structure is long for firm service life, can effectively resist ambient pressure；Shield effectiveness is good, can drop The low impact on toy.

In particular, air cushion 35 volume is slightly less than the volume of chamber 34, internal ring 31, Outer shroud 32 and supporter 33 are connected as a single entity structure, and internal ring 31, outer shroud 32 and Support body 33, for make for PA material, prevents that baiting hot melt on tooth 41 has rubber layer 41a, interior There is between insulating barrier 2 and internal ring 31 annular fire prevention cushion pad 7.

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, anti-bait screen layer 4, anti-tear Biting teeth 41, metal screen layer 5, external insulation layer 6, rubber layer 41a, annular fire prevention buffering Pad 7 terms such as grade, but be not precluded from using the probability of other term.Use these terms It is only used to describe and explain essence of the present utility model more easily；They are explained The restriction becoming any one additional is all contrary with this utility model spirit.
