Description
Technical field
The utility model relates to cable cover(ing)s, more specifically to a kind of cable cover(ing) with high-wearing feature.
Background technique
It is exactly to be made of the conductor and external insulating protective layer of one or more mutually insulated for cable is popular, by electric power
Or information is transferred to the conducting wire at another place from one.With the rapid development of economy, more and more places need cable to transmit
Electric power or other information, therefore also have tightened up requirement to the manufacture of cable.Cable cover(ing) is the indispensable centre of cable
Structure division plays a part of protecting cable, guarantees the energization safety of cable, allows copper wire and water, the isolation of the media such as air avoids
There is leaky.In use, to the insulating properties of cable, tensile strength, wear-resisting property, cold tolerance and anti-flammability
Can there are strict requirements；Therefore the properties for cable jacket material being continuously improved are the broken ball demand of economy and society anyway.
Existing cable structure can generally be divided into conductor, insulating layer, shielded layer and four part of restrictive coating composition.Because of cable
It is required that insulating materials has excellent electrical insulation capability, it often cannot be considered in terms of to extraneous protective capacities, so for the external world
The resistance of various external force, corrosion-resistant, anti-aging and fire protecting performance resist power often wretched insufficiency, and restrictive coating is exactly to make up
The key point of problems.The restrictive coating of Gu Yaoqiu cable should have the good characteristics such as insulation, corrosion-resistant, non-aging.
Common sheath material has fiber, General Purpose Rubber, plastics and nylon etc., compared with these materials, silicon rubber tool
There are good high temperature resistant, low temperature resistant, electrical insulating property, oxytolerant ageing resistance, chemical stability etc., and soft, therefore should
The range of material application is also very extensive.But silastic material is easy to extend, elongation >=700%, and cable internal junction
Structure elongation is little, especially pulls under effect after long-time use, the restrictive coating of silicon rubber can be made to cable internal structure
Protection not enough, causes the reduction of cable service life.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide a kind of with high-wearing feature
Cable cover(ing) can be effectively reduced the elongation of silastic material sheath, the tensile strength and wearability of sheath be improved, to increase
Strong protective effect of the silicone rubber jacket to cable, extends the service life of cable.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of cable cover(ing) with high-wearing feature, comprising: core strueture, insulating layer, the screen being successively arranged from inside to outside
Cover layer and restrictive coating, further includes: the wear resistant outer layer being coated on restrictive coating, the wear resistant outer layer are made of PTFE material, the screen
Cover layer and be also made of PTFE material, the insulating layer, shielded layer, restrictive coating and wear resistant outer layer thickness ratio be 2~4:1:2~4:
1~3, fiber web layer is also embedded in the restrictive coating.
Pass through alite paste between the insulating layer, shielded layer, restrictive coating and wear resistant outer layer to connect.
The fiber web layer is with a thickness of 0.2~0.4mm.
The fiber web layer is KEVLAR fiber filament, polytetrafluoroethylene (PTFE) sewing thread or heat-resisting aramid fiber.
In the above technical solution, a kind of cable cover(ing) with high-wearing feature provided by the utility model can have
Effect reduces the elongation of silicone rubber material restrictive coating, improves the tensile strength of restrictive coating, enhances the wearability of restrictive coating, thus
Protective effect of the restrictive coating to inside cable is enhanced, the more effective service life for extending cable.In addition, the electricity of the utility model
Cable sheath is also applied for various signal cables, the characteristics and advantages without influencing silicon rubber.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model cable cover(ing).
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of cable cover(ing) with high-wearing feature provided by the utility model, comprising: successively
Core strueture 1, insulating layer 2, shielded layer 3 and the restrictive coating 4 being arranged from inside to outside, above-mentioned is prior art part, herein just not
It repeats again.Unlike the prior art, further includes: the wear resistant outer layer 5 being coated on restrictive coating 4, the wear resistant outer layer 5 use
PTFE material is made, its outmost surface is made to have good wearability, anticorrosive property, and the shielded layer 3 also uses PTFE material
It is made, can play the interference signal that preferably shielding is extraneous, the insulating layer 2, shielded layer 3, restrictive coating 4 and wear resistant outer layer 5
Thickness ratio is 2~4:1:2~4:1~3, selects 3:1:3:3 in the present embodiment, is also embedded with fiber web layer in the restrictive coating 4
6, or be wrapped on restrictive coating 4.
Preferably, connected between the insulating layer 2, shielded layer 3, restrictive coating 4 and wear resistant outer layer 5 by alite paste, from
And synthesize an entirety.
Preferably, 6 thickness of fiber web layer selects 0.2~0.4mm preferable.
Preferably, KEVLAR fiber filament, polytetrafluoroethylene (PTFE) sewing thread or heat-resisting aramid fiber etc. can be selected in the fiber web layer 6
Preferably.
In conclusion the elongation of silicone rubber material restrictive coating can be effectively reduced in the cable cover(ing) of the utility model, improve
The tensile strength of restrictive coating enhances the wearability of restrictive coating, to enhance protective effect of the restrictive coating to inside cable, more
Effectively extend the service life of cable.In addition, the cable cover(ing) of the utility model is also applied for various signal cables, without influencing
The characteristics and advantages of silicon rubber.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
