Abstract
The utility model discloses a kind of self-rolling low-temperature protection sets, include separation layer and weathering protective layer successively from the inside to the outside, and separation layer uses polytetrafluoroethylene film, weathering protective layer to be prepared by weather resistant materials.The self-rolling low-temperature protection set of the utility model has many advantages, such as good weatherability, hygroscopicity, organic solvent-resistant, anti-interference, tear-proof, insulation, fire-retardant, radioresistance, compressible and bending; it is sleeved on outside cable; good weather-proof, fire-retardant, abrasion resistant effect can be played; and obstruction is not will produce in cable bend or winding, it is ensured that cable steady operation under low temperature, weather defective mode.
Description
Technical field
The utility model is related to cable low-temperature protection fields, and in particular to a kind of self-rolling low-temperature protection set.
Background technology
It in aerospace and electronics field, is commonly used and arrives various cables, however partial cables can be directly sudden and violent for a long time
Dew in air, is easy, by various natural environments and artificial destruction, existing cable wave prevention sleeve service life to be caused to decline,
And cause cable service life and safety by significant impact, to influence the electricity consumptions such as aerospace and electronics.
Defect existing for existing cable protective sleeve：Not weather-proof and fire-retardant, cable protective sleeve in use can be by
It is comprehensive caused by illumination, cold and hot, wind and rain, bacterium etc. to destroy, cause cable is exposed to influence its use；Not flexible or bending process
Trouble, the protective case that existing cable protective case is generally used hard material or formed using weather-proof body and connector sleeve.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of self-rolling low-temperature protection set are provided, by this
Protective case is sleeved on outside cable, plays good weather-proof, fire-retardant, abrasion resistant effect, and not will produce in cable bend or winding
It hinders, it is ensured that cable steady operation under low temperature, weather defective mode.
To achieve the goals above, the technical solution adopted in the utility model is：A kind of self-rolling low-temperature protection set, by interior
To outside successively include separation layer and weathering protective layer, the separation layer use polytetrafluoroethylene film, the weathering protective layer by
Weather resistant materials are prepared.
The weathering protective layer is by the poly- phthalein amine fiber Nomex of meta-aromatic and the PET braidings of poly terephthalic acid resinoid
Made of weather-proof cloth, count be not less than 95%.
The low-temperature protection set has from after knitting forming from volume property, can form cylindrical shape from volume, be adapted to cable profile, cover
It need not apply additional pressure again when protecting cable.
The beneficial effects of the utility model：
1. the separation layer of the utility model uses polytetrafluoroethylene film in the case where temperature and frequency are widely varied,
Its change in dielectric constant is small；And volume resistivity will not change long-time is impregnated in water, stability is better than it
His insulating materials.
2. the weathering protective layer of the utility model is by the poly- phthalein amine fiber Nomex of meta-aromatic and poly terephthalic acid class tree
Weather-proof cloth made of fat PET braidings, count is not less than 95%, material novel environment friendly, weather-proof, fire-retardant, chemicals-resistant,
Hydrolysis, wear-resisting, corrosion-resistant, radiation resistance, satisfactory mechanical property, fracture strength is high, and elongation is larger, soft, does not melt,
Smokescope is low when burning, and calorific value is low, wash resistant, keeps good through repeatedly washing flame retardant property, has preferable size steady
It is qualitative, while the bending softness of wave prevention sleeve is also substantially increased, it not will produce obstruction in cable bend or winding, it is ensured that
Cable is in low temperature, the bad steady operation under having disturbance state of weather.
Description of the drawings
Fig. 1 is the structural schematic diagram of the self-rolling low-temperature protection set set shield cable of the utility model；
Fig. 2 is the sectional view of the self-rolling low-temperature protection set of the utility model；
Wherein, 1- separation layers, 2- weathering protective layers, 3- self-rolling low-temperature protection sets, 4- cables.
Specific implementation mode
Below by way of specific implementation mode, and in conjunction with attached drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of self-rolling low-temperature protection set includes separation layer 1 and weather-proof protection successively from the inside to the outside
Layer 2, separation layer 1 use polytetrafluoroethylene film, and weathering protective layer is by the poly- phthalein amine fiber Nomex of meta-aromatic and gathers to benzene two
Weather-proof cloth made of the PET braidings of formic acid resinoid, count are not less than 95%.The low-temperature protection set from after knitting forming from
Volume forms cylindrical shape, is adapted to cable profile, need not apply additional pressure again when set protects cable.
In specific implementation, corresponding structure setting and material selection are respectively：
Using polytetrafluoroethylene film in the case where temperature and frequency are widely varied, dielectric constant becomes separation layer 1
Change small；And volume resistivity will not change long-time is impregnated in water, stability is better than other insulating materials.
Weathering protective layer 2 is woven by meta-aromatic poly- phthalein amine fiber Nomex and poly terephthalic acid resinoid PET
Weather-proof cloth, count be not less than 95%, material novel environment friendly, weather-proof, fire-retardant, chemicals-resistant, hydrolysis, it is wear-resisting,
Corrosion-resistant, radiation resistance, satisfactory mechanical property, fracture strength are high, and elongation is larger, soft, does not melt, and smog is dense when burning
Spend low, and calorific value is low, wash resistant, keeps good through repeatedly washing flame retardant property, has preferable dimensional stability, while also big
The big bending softness for improving wave prevention sleeve, not will produce obstruction in cable bend or winding.
The self-rolling low-temperature protection set of the utility model has good weatherability, hygroscopicity, organic solvent-resistant, resists and do
Disturb, tear-proof, insulation, fire-retardant, radioresistance, compressible and bending the advantages that, be sleeved on outside cable, can play good resistance to
It waits, fire-retardant, abrasion resistant effect, and not will produce obstruction in cable bend or winding, it is ensured that cable is in low temperature, weather defective mode
Lower steady operation.
