Description

A kind of super abrasive electric automobile interconnection cable

Technical field

The utility model is related to a kind of cable, especially a kind of super abrasive electric automobile interconnection cable.

Background technology

The structure of cable that electric automobile inside in the market uses usually conductor, insulating barrier, outer braid shielded Layer and restrictive coating.The sheath material of cable is the materials such as cross-linking radiation polyolefin, TPE or PVC, for using said structure and shield Operationally there is different degrees of phase mutual friction, lasting vibration meeting in circulation, installation and electric automobile in the cable of cover material Sheath to electric automobile inside cable causes serious abrasion, greatly reduces the use longevity of electric automobile interconnection cable Life.

Existing electronic vehicular cable also has that shield effectiveness is poor.

Utility model content

To solve the above problems, the utility model provides a kind of high intensity, high-resistance wear-resistant, antidetonation, shield effectiveness good one Super abrasive electric automobile interconnection cable is planted, concrete technical scheme is：

A kind of super abrasive electric automobile interconnection cable, the cable is followed successively by conductor, insulating barrier, aluminium foil from inside to outside Lapping layer, screen layer, middle tegillum, acrylic fibers braiding layer, nylon outer jacket.

The insulating barrier is 125 degree of cross-linking radiation thermosetting polyolefin layers.

The aluminium foil lapping layer is aluminium-plastic tape.

The aluminium-plastic tape is the band that aluminium foil and plastics PE films are composited.

The rate of putting up of the aluminium-plastic tape is not less than 25%.

The screen layer is braiding tinned copper wire layer.

The aluminium foil of the aluminium-plastic tape is located at outside, is contacted with braiding tinned copper wire layer.

The middle tegillum is thermoplasticity TPU layer.

The acrylic fibers braiding layer is bonded into an entirety with nylon outer jacket.

After conductor is from the 6 class flexible conductor monofilament elder generation bundle strand of the requirements of GB/T 3956 is met, then it is multiple in the same direction twist, when twisting again into Cable machine is furnished with back-twist device, can eliminate the multiple stress for twisting and producing, and makes wire rod more rounding, softness.

Insulating barrier uses 125 degree cross-linking radiation thermosetting polyolefine materials, the high-quality and efficient fire retardant of addition, crosslinking agent, Antismoke agent, antioxidant and other processing aids, are formed through mixing, plasticizing, granulation, and high molecular polymer from chain is made by irradiation The thermoplastic of structure is changed into the thermosets of space network.Thermosetting polyolefin temperature classification is high, chemically-resistant Corrosion, is not dissolved in oil and organic solvent；Tensile strength, wearability, crushing resistance, shock resistance, tear-proof and the machinery such as anti-shearing Performance is good.

Aluminium foil lapping layer is aluminium-plastic tape, and aluminium-plastic tape is that aluminium foil and plastics PE films are combined with each other, with one side Electric conductivity.In the production of electric automobile inner high voltage cable, the wrapped aluminium-plastic tape outside insulating barrier, conductive aluminium foil surface with Braiding tinned copper wire layer is in contact, and effectively improves the shield effectiveness of cable, reduces transfger impedance, solves braiding tinned copper wire layer Weak problem is shielded to high-frequency signal.

Screen layer is formed by tinned copper wire braiding, and tinned copper wire braiding is wrapped to be taken plastic-aluminum combined, aluminium-plastic tape Rate is put up not less than 25%, wrapped aluminium-plastic tape is the supplement to tinned copper wire, shielding rate is reached 100%, improves shielding Effect.

Middle tegillum uses thermoplasticity TPU materials, and TPU materials have good wear-resisting, and tensile strength is high, tear resistance The good physical property such as by force, and surface relative smooth can produce relative slip, reduce the phase mutual friction between material, play Good transitional function.

Acrylic fibers braiding layer is to be covered in TPU layer outside, and acrylic fibers braiding layer is worked out by acrylic fiber, good with having Resisting combustibility, wearability and weathering capabilities also very well, can play good anti-wear performance.When nylon outer jacket is extruded, nitrile Synthetic fibre braiding layer can effectively be bonded into an entirety with nylon outer jacket, improve the hole tear resistance of sheath and resisting for cable entirety Drawing property.

Nylon material as oversheath, with good resisting combustibility, wearability and weathering capabilities；Specific tensile strength is high In metal, specific compress strength is equally matched with metal, but its rigidity is not as good as metal.Tensile strength close to yield strength, than ABS doubles many；Fatigue performance is protruded, and product is through repeatedly flexion remains to keep original mechanical strength repeatedly；Surface is smooth, rubs Wipe coefficient small, it is wear-resisting.Nylon is corrosion-resistant, very alkaline-resisting and most of saline solutions, goes back weak acid resistant, machine oil, gasoline, the chemical combination of resistance to aromatic hydrocarbons Thing and common solvent, it is inert to aromatic compound, the erosion of gasoline, oil, fat, alcohol, weak base etc. can be resisted and had very Good ageing resistance；Excellent electric property.Electrical insulating property is good, and the volume resistance of nylon is very high, breakdown voltage resistant Gao Gan Under dry environment, can be as power frequency insulating materials, even if still having preferable electrical insulating property under high humidity environment.

The utility model has the advantages that compared with prior art：

A kind of super abrasive electric automobile interconnection cable that the utility model is provided has oil resistant, water-fast moistureproof, corrosion resistant Erosion, acid and alkali-resistance, mechanical resistant stress, high-low temperature resistant, high fire-retardance, non-toxic nature, weather resisteant high, high-wearing feature, mechanical performance are strong, screen Cover effect good, it is ensured that cable long-term safety under various complex environments is used, use reliable, stabilization, long service life.
