Band and oversheath；The cable core, the waterstop and the oversheath are set gradually from inside to outside；The inner core is led including interior
It body, the insulating layer on the outer surface of the inner wire and is filled between the inner wire and the insulating layer
First water blocking yarn.
As being further improved for above-mentioned water-proof cable, between the insulating layer and the waterstop, it is also filled with second
Water blocking yarn.
As being further improved for above-mentioned water-proof cable, the inner wire is twisted by more copper wire.
As being further improved for above-mentioned water-proof cable, the cable core is by single or two or two or more inner core structures
Into.
As being further improved for above-mentioned water-proof cable, the oversheath uses polythene material.
As being further improved for above-mentioned water-proof cable, the oversheath uses butyronitrile polyvinyl chloride.
As being further improved for above-mentioned water-proof cable, the insulating layer is using ethylene propylene rubber insulated.
The water-proof cable of the utility model is provided with waterstop first between cable core and oversheath, forms first and blocks water
Protective layer, and the first water blocking yarn is equipped between inner wire and insulating layer, longitudinal water-blocking layer is formed, reaches conductor and is hindered with insulating layer
Water from internal protection inner wire waterproof, avoids the inner wire inside cable core from leaking electricity, charges water body, cause security risk, especially
It is to work as water-proof cable long period of soaking in water, when insulating layer aging causes insulation damage layer, avoids its thermal breakdown, greatly shorten electricity
The service life of cable, causes serious consequence；Further improve is also filled with the second water blocking yarn between insulating layer and waterstop,
For the further oversheath that improves using polythene material, especially butyronitrile polyvinyl chloride, high density attribute, molecular structure are close
It is real, radial water-resisting is formed again so that moisture or moisture are difficult through its structure, effectively inner wire are avoided to intake from diametric(al)
Electric leakage, the serious consequence that damage object is caused to hurt sb.'s feelings.As it can be seen that the water-proof cable of the utility model, simple in structure, easy for installation, waterproof
Moisture resistance effect is good, safe, service life is long.

Specific embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to practical new herein
Type, which is done, more comprehensively, meticulously to be described, but the scope of protection of the utility model is not limited to specific examples below.
Unless otherwise defined, all technical terms used hereinafter are generally understood meaning phase with those skilled in the art
Together.Technical term used herein is intended merely to the purpose of description specific embodiment, is not intended to the limitation present invention's
Protection domain.
It please refers to shown in Figure of description 1, it is shown that a specific embodiment of the utility model.A kind of water-proof cable,
Including the cable core 100, waterstop 200 and oversheath 300 being made of inner core 10.Cable core 100, waterstop 200 and oversheath 300 by
It is interior and set gradually outside.Wherein, inner core 10, the insulating layer 12 including inner wire 11, on the outer surface of inner wire 11, with
And it is filled in the first water blocking yarn 13 between inner wire 11 and insulating layer 12.
The water-proof cable of the utility model, is provided with waterstop between cable core and oversheath, forms first and blocks water protection
Layer, and the first water blocking yarn is equipped between inner wire and insulating layer, longitudinal water-blocking layer is formed, reaches conductor and blocks water with insulating layer,
From internal protection inner wire waterproof, the inner wire inside cable core is avoided to leak electricity, charges water body, causes security risk, especially
When water-proof cable long period of soaking in water, insulating layer aging cause insulation damage layer when, avoid its thermal breakdown, greatly shorten cable
Service life, cause serious consequence.It is not only simple in structure, is easy for installation, and under long-term immersion and larger hydraulic pressure,
It throws away with preferable waterproof moisture resistance effect, there are good electrical insulation properties, it is safe, service life is long.
In an advantageous embodiment, in order to further improve the total cross-section block-water effect of water-proof cable, insulating layer 12 with
Between waterstop 200, the second water blocking yarn 400 is also filled with, another layer longitudinal water-blocking layer is formed, further avoids inside cable core
Inner wire leaks electricity, and improves the safety of cable and service life in water.
Specifically, inner wire 11 are twisted by more copper wire.Cable core 100 by it is single or two or two or more in
Core 10 is formed (as described in Figure 1, to be made of, structure size of noticeable each inner core 10 etc. can unanimously be set three inner cores 10
It puts, can also set respectively).It should be noted that inner wire is twisted preferably using the tin plating annealed copper conductor of the 6th class in inner wire
It closes in gap plus around several first water blocking yarns, which contains high temperature resistant water-proofing powder, because insulating layer is rubber steam
Vulcanization, steam vulcanization (cure) temperature are up to 170 DEG C, and according to common water blocking yarn, water-proofing powder is vulnerable at high temperature, it is impossible to be led in playing
Body total cross-section block-water effect.
In a specific embodiment, oversheath 300 uses polythene material.Oversheath uses high-density polyethylene as a result,
Alkene material, molecular structure is closely knit, and moisture or moisture penetrate its structure very much, diametrically with good block-water effect.
More specifically, oversheath 300 uses butyronitrile polyvinyl chloride.In this way, oversheath uses butyronitrile polyvinyl chloride, cable core and oversheath
It bonds closely, meanwhile, butyronitrile pvc sheath has good flexibility and oil resistivity, suitable for complicated underwater environment.
In above-described embodiment, it is preferred that insulating layer 12 is using ethylene propylene rubber insulated.In this way, insulating layer uses insulation performance
Good is ethylene propylene rubber insulated, and insulating exruded mode is squash type, is prevented in cable core using filling water blocking yarn and wrapped waterstop are compound
Hydraulic art prevents the gap in cable core from penetrating into moisture.
In conclusion the water-proof cable of the utility model has, simple in structure, easy for installation, flexibility is good, bending radius
Small, good waterproof performance, sunlight resistance can be good, the features such as security reliability, while have water blocking tape layer, water blocking yarn longitudinal water-blocking, outer
The total cross-section waterproof advantage of sheath radial water-resisting, the first water blocking yarn filled between inner wire and insulating layer, insulating layer is with blocking water
The second water blocking yarn and waterstop filled between band, form the longitudinal water-blocking of water-proof cable, and oversheath uses high-density polyethylene
Alkene material, molecular structure is closely knit, and moisture or moisture penetrate its structure very much, has good block-water effect from diametric(al),
Form the radial water-resisting of water-proof cable.This water-proof cable is the common selection of fountain landscape, in long-term immersion and larger water
Pressure, it is safe, service life is long still with good electrical insulation properties.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that the common skill for this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
