Abstract
The utility model discloses a heat shrink tube with a shielding function. The heat shrink tube comprises a heat shrink tube body with a hollow structure, and a flame retardation layer coated on an external surface of the heat shrink tube body; a tin ring is sleeved inside the heat shrink tube body; and a plastic ring is sleeved at two sides of the tin ring inside the heat shrink tube body. The heat shrink tube is simple in structure, has good sealing performance and shielding performance, and is provided with the fireproof function.
Description
Technical field
The utility model relates to the heat-shrink tube field, is specifically related to a kind of heat-shrink tube with function of shielding.
Background technology
Heat-shrink tube is a kind of polyolefin material heat-shrinkable tube with high-temperature shrinkage, soft fire-retardant, insulation corrosion protection function.It at room temperature is glassy state, becomes elastomeric state after the heating, shrinks rapidly after cooling.Because its characteristic, heat-shrink tube is widely used in antirust, the corrosion protection place of the insulation protection of various wire harness, solder joint, inductance and metal tube, rod.In order to adapt to various different application place, people have invented various heat-shrink tubes, such as isolating shrinkable tube, shielding heat-shrink tube, anti-skid heat shrinkable tube etc.
And be that all trades and professions cable connects and the important devices of the sealing of cable ground connection, shielding with the heat-shrink tube of function of shielding, particularly for the place of some sealing properties, the structure of the cable connecting device that shielding properties is high and performance thereof directly affect the electric energy consume and are connected texts with cable.
On the other hand, it mainly is the mode that adopts the rear protection process of that traditional welding that cable in the market connects, and this traditional welding adds guard method, although can guarantee welding effect,, its operation is wasted time and energy, and sealing effectiveness is difficult to guarantee.Simultaneously, for the cable that is under the not good and long-term work environment of radiating effect, be easy to cause temperature to raise, cause cable on fire, produce fire.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of simple in structure, good sealing effect, shield effectiveness is good and have the heat-shrink tube of fire-proof function.
For achieving the above object, a kind of heat-shrink tube with function of shielding of the utility model, comprise hollow structure the heat-shrink tube body, be coated on the flame-retardant layer of described heat-shrink tube outer surface of tube body, be arranged with the tin ring in the described heat-shrink tube body, in the heat-shrink tube body of described tin ring both sides, be arranged with the glue ring.
Preferred on the basis of such scheme, described heat-shrink tube body is fluorine elasticity body.
Preferred on the basis of such scheme, described flame-retardant layer is the halogen-free flameproof layer.
Preferred on the basis of such scheme, the shrinkage of described glue ring is different from the shrinkage of heat-shrink tube body.
Preferred on the basis of such scheme, described flame-retardant layer is provided with oxygen barrier heat resistant glass cloth belting layer outward.
The utility model compared with prior art, its beneficial effect is: the utility model is simple and reasonable, shielding heat-shrink tube bilateral adopts two glue ring sealed construction designs, for the sealing of cable junction provides dual assurance, guarantee shielding, the pyrocondensation texts of cable junction under the adverse circumstances such as hot and humid.The utility model is coated with a flame-retardant layer at the heat-shrink tube outer surface of tube body in addition, can effectively improve its fire retardant performance.Heat-shrink tube adopts fluorine elasticity body to have transparent, fire-retardant, high temperature resistant, oil resistant, the characteristic such as corrosion-resistant, wear-resistant.The problems such as the utility model is conducive to solve above-mentionedly wastes time and energy, cost of labor height, failure welding.
Description of drawings
Fig. 1 is a kind of heat-shrink tube overall structure schematic diagram with function of shielding of the present utility model.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
See also Fig. 1, the utility model provides a kind of heat-shrink tube with function of shielding, it comprise hollow structure heat-shrink tube body 10, be coated on the flame-retardant layer 20 of described heat-shrink tube body 10 outer surfaces, wherein, described heat-shrink tube body 10 is fluorine elasticity bodys, be arranged with tin ring 40 in the described heat-shrink tube body 10, in the heat-shrink tube body 10 of these tin ring 40 both sides, be arranged with glue ring 30.As the preferred version of this case, the shrinkage of described glue ring 30 is different from the shrinkage of heat-shrink tube body 10, the described flame-retardant layer 20 outer oxygen barrier heat resistant glass cloth belting layers (not shown) that are provided with.
During use, through high-temperature baking, heat-shrink tube tightly is fixed on the protected cable; two ends glue ring 30 plays the protection sealing function; prevent that air, steam etc. from entering the oxidation cable, 40 on middle tin ring is coated on after thawing and is connected the cable surface, and cable is tightly welded together.Simultaneously, the flame-retardant layer 20 that is coated on heat-shrink tube body 10 surfaces can prevent effectively that it from producing spontaneous combustion in the process of high-temperature baking, prevents it because of the high-temperature heating fired vapour, and when making it in use run into high-temperature condition, heat-shrink tube body 10 directly is heated.Produce the gas of contaminated environment in order to prevent that flame-retardant layer 20 is heated, described flame-retardant layer 20 is the halogen-free flameproof layer.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection range of the utility model claim all.
Claims (5)
1. heat-shrink tube with function of shielding, it is characterized in that: comprise hollow structure the heat-shrink tube body, be coated on the flame-retardant layer of described heat-shrink tube outer surface of tube body, be arranged with the tin ring in the described heat-shrink tube body, in the heat-shrink tube body of described tin ring both sides, be arranged with the glue ring.
