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.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1,2 and 3, as the embodiments of the present invention it is a kind of fire prevention isolation cable, including cable core 4,
Insulating layer 3, fireproof coating layer 2, clockwork spring 5 and protective layer 1 are insulating layer 3,3 outer cladding fireproof coating of insulating layer outside cable core 4
Layer 2,2 outer cover of fireproof coating layer are equipped with multiple clockwork springs 5, and in the present embodiment, the clockwork spring 5 rolls tightly piece and hair using stainless steel
The distance between item 5 is equal, and the outside of the fireproof coating layer 2 and clockwork spring 5 is protective layer 1, and the clockwork spring 5 is in protective layer 1
When be that the cable core 4 can be supported when the clockwork spring 5 is in releasing orientation, and the protective layer 1 in compressive state
It is provided with resin-bonded mastic between fireproof coating layer 2 and clockwork spring 5 respectively, resin-bonded mastic has durability, high temperature resistant, impermeability, close
Reality and high bonding force and extremely strong waterproof and anticorrosion effect, can effectively improve the service life of cable, even protecting
Sheath rupture, resin-bonded mastic also can be very good hermetically-sealed cable core 4, guarantee its normal use, in addition, also functioning to the work of insulation
With.By being provided with multiple roll film shape clockwork springs 5 in existing cable, the clockwork spring 5 is in compression in the protective layer of cable
State replaces traditional bellows by the way that clockwork spring 5 is arranged, different to keep away using the elasticity of clockwork spring 5 and the thickness of protective layer 1
Exempt from the damage that cable is caused when being bent cabling.
In the present embodiment, the outer diameter at the every place of the protective layer 1 is identical, to guarantee to be wrapped in the protective layer 1 at clockwork spring 5
Than relatively thin, in cable generation overload or short circuit, at a temperature of same, being wrapped in the meeting of protective layer 1 at clockwork spring 5, first burning is broken, is in
The constraint that the clockwork spring 5 of impaction state loses protective layer 1, which can scatter, supports cable core 4, so that isolated from power be got up, keeps away
Exempt from directly to contact with surrounding articles.
Preferably, the clockwork spring 5 is bonded with fireproof coating layer 2 by epoxy AB glue, using this high-temperature plastic, when condensation
Between it is fast, do not need that tough and tensile film can be formed in the case of a high temperature by curing agent, in other embodiments, the clockwork spring 5 can also
With fixed using other modes and fireproof coating layer 2.
