Description
Technical field
The utility model relates to technical field of cables, more particularly to a kind of freeze proof anti-fracture cable.
Background technique
Cable is the general designation of optical cable, cable and other items.There are many uses of the cable, is mainly used for control installation, connection is set
It is standby, the multiple actions such as transmit electric power, be a common and indispensable thing in daily life.Since cable charges, so
It is especially careful that installation needs.
Cable freezing tolerance on existing market is poor, so that cable can not keep steady when outdoor temperature is lower
Fixed performance is being installed cable and is being transported to be unfavorable for the protection to cable, and the cable portion has ductility
During, it can not effectively avoid cable from leading to the case where damaging because of shaking, therefore be unfavorable for promoting.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is freeze proof anti-fracture
Cable.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of freeze proof anti-fracture cable, including inner core are designed, compound sleeve is equipped with internal protective cover on the outside of the inner core, described interior
The appearance compound sleeve of protective case is equipped with extended layer, compound sticking matcoveredn on the outside of the extended layer, and the extended layer includes set
The insulated sponge layer being located on the outside of internal protective cover, insulated sponge layer outer surface compound sticking have memory cotton layer, and memory sponge
The thickness proportion of layer and insulated sponge layer is 1:1.
Preferably, the protective layer includes rubber-plastic sponge layer of the compound sticking in extended layer outer surface, the rubber-plastic sponge
Layer outer surface compound sticking has a polytene heat-insulation layer, and the outer surface of the polytene heat-insulation layer is bonded with rock wool layer, and rock wool layer,
The thickness proportion of polytene heat-insulation layer and rubber-plastic sponge layer is 1:1:2.
Preferably, multiple connecting columns, and the fan-shaped distribution of multiple connecting columns are connected between the extended layer and protective layer,
The connecting column is between memory cotton layer and rubber-plastic sponge layer.
Preferably, the outer surface of the protective layer, which is coated with, freeze proof splits oxidant layer.
The utility model proposes the freeze proof anti-fracture cable of one kind, beneficial effect is: the freeze proof anti-fracture cable has
Freeze proof effect still can keep stable state in the environment of low temperature, will not extend there is a phenomenon where being broken easily to lose
The service life of cable, and the cable has the advantages of draftability, so as to be sent out during transport and installation
The raw situation lost, therefore be conducive to promote.
Detailed description of the invention
Fig. 1 be the utility model proposes the freeze proof anti-fracture cable of one kind structure sectional view.
Fig. 2 be the utility model proposes the freeze proof anti-fracture cable of one kind protective layer schematic enlarged-scale view.
Fig. 3 be the utility model proposes the freeze proof anti-fracture cable of one kind extended layer schematic enlarged-scale view.
In figure: freeze proof to split oxidant layer 1, internal protective cover 2, protective layer 3, rock wool layer 31, polytene heat-insulation layer 32, rubber-plastic sponge layer
33, extended layer 4, memory cotton layer 41, insulated sponge layer 42, connecting column 5, inner core 6.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of freeze proof anti-fracture cable, including inner core 6,6 outside compound sleeve of inner core are equipped with internal protective cover 2,
The design of internal protective cover 2 can play the role of protection to inner core 6, enable the work of 6 normal table of inner core.
The outer surface of protective layer 3 be coated with it is freeze proof split oxidant layer 1, it is freeze proof split agent can low temperature, drying environment in play
Cold-proof effect, so that cable can prevent the case where being broken.
The appearance compound sleeve of internal protective cover 2 is equipped with extended layer 4, and extended layer 4 includes the insulation for being set in 2 outside of internal protective cover
Froth bed 42,42 outer surface compound sticking of insulated sponge layer have memory cotton layer 41, and memory cotton layer 41 and insulated sponge layer 42
Thickness proportion is 1:1, and memory sponge has the characteristics of low resilience, and low resilience refers to that material has the ability slowly deformed, and external force makes it
After deformation, reply original shape with will be slow, i.e. material has a kind of characteristic for having both stickiness and elasticity, impact kinetic energy is absorbed,
And Reusability and can be unlikely to be permanently deformed, insulating foams have slim and graceful, heat-insulated, damping the characteristic of quality, to pass through note
Recall the design that cotton layer 41 is 1:1 with the thickness proportion of insulated sponge layer 42, enable to the protective layer 4 can have insulation, every
Heat, the effect of damping and extension, so that the cable has stretchable feature.
Multiple connecting columns 5, and the fan-shaped distribution of multiple connecting columns 5, connecting column 5 are connected between extended layer 4 and protective layer 3
Between memory cotton layer 41 and rubber-plastic sponge layer 33, the design of connecting column 5 is enabled between extended layer 4 and protective layer 3
Connect more stable, the stability of raising cable entirety.
4 outside compound sticking matcoveredn 3 of extended layer, protective layer 3 include rubber and plastic of the compound sticking in 4 outer surface of extended layer
Spongy layer 33,33 outer surface compound sticking of rubber-plastic sponge layer have polytene heat-insulation layer 32, and the outer surface of polytene heat-insulation layer 32 is viscous
It is connected to rock wool layer 31, and the thickness proportion of rock wool layer 31, polytene heat-insulation layer 32 and rubber-plastic sponge layer 33 is 1:1:2, rubber and plastic
Sponge has that density is small, quality is slim and graceful, restoring force is strong and the effect of damping, and polytene heat-insulation material water imbibition is small, insulating properties
Good and physical property is stablized, and rock wool has high reply, damping and freeze proof effect, improves rock wool layer 31, polytene heat-insulation
The thickness proportion of layer 32 and rubber-plastic sponge layer 33 is the design of 1:1:2, can be improved cryoprotective effects and the drawing of cable entirety
The ability of liter, is conducive to extend the service life of cable.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
