Description
Technical field
The present invention relates to a kind of cable, especially relate to a kind of new-energy automobile inside high tension cable, belong to new forms of energy
Automobile technical field of cables.
Background technology
Cable is the bridge between power supply unit and electrical equipment, plays the effect of transmission electric energy.It is widely used, therefore fault
The most often occur, below brief analysis high tension cable FAQs Producing reason, be roughly divided into following a few class: producer manufactures
Reason, construction quality reason, designing unit's design reasons, external force destroy four big classes. and common GB PVC automobile electric wire has QVR
And QVR-105, but because of reform and opening-up, world community auto vendor China Jun You co-partnership company, these companies are by various countries
The standard of automobile electric wire be brought in China, the labour force utilizing China cheap is its all kinds of automotive wire bundles of production, main state
Family is shown, Japanese (Japan, Korea S, Latin America, Southeast Asia etc.), U.S. system (U.S., Britain, Canada), German (Germany, method
State).Can be divided into according to working environment: 70 degree, 105 degree, 115 degree.
It is a kind of for electric connection line for connecting cable with high pressure inside new-energy automobile, and the primary high pressure for vehicle interior passes
Defeated.Cable flexible conductor does not require nothing more than has good flexibility, in order in narrow space or when similar conveniently
Lay；Tool needs have good anti-flammability, to meet higher fire-protection rating requirement；There is the strongest shield effectiveness, shield
Cover the impact for external environment condition of the electromagnetic interference in the external world and the electromagnetism of internal high pressure and the generation of high electric current.Automobile the most both at home and abroad
Aluminium-plastic tape+braiding is used to reach shield effectiveness by the cable overwhelming majority, but aluminum and copper Long contact time, electricity can be accelerated
The oxidation of cable parts, service life is short, does not reaches the life length of universal automobile.As CN 105374415 A is provided with " a kind of
Electric automobile inner high voltage cable ", CN 104376903 A be provided with " a kind of electric automobile inside high tension cable and making thereof
Method ", the electric wire that above-mentioned prior art is provided has easily oxidation, and conductor, braid are the loosest, cause cable resistance to
High pressure weak effect.
Summary of the invention

The mode extruded is coated on outside interior belting layer.Being provided with screen layer, the cable being is safer during using.
Preferably, semiconductive shielding layer is 125 DEG C or 150 DEG C of semiconductive crosslinked polyethylenes or polyolefin, with the side extruded
Formula is coated on outside insulating barrier.
Preferably, woven shield be tin-plating round copper wire or naked circular copper wire material braiding form, woven shield is coated on
Outside semiconductive shielding layer.
Shielding is to the isolation carrying out metal between two area of space, to control electric field, magnetic field and electromagnetic wave by one
Region is to the sensing in another region and radiation.Specifically, it is simply that with shield by component, circuit, molectron, cable or whole
The interference source of individual system is surrounded, and prevents from disturbing electromagnetic field to external diffusion；Circuit, equipment or system bag will be received with shield
Fence up, prevent them from being affected by external electromagnetic field.Contrast prior art is not provided with screen layer, and its cable uses process
In the most inevitably affected by external magnetic field.
Preferably, outer belting layer is cable paper tape, by vertical bag or wrapped in the way of be coated on outside woven shield.Arrange many
Layer cable paper tape not only can effectively ensure the aspect performance such as its dielectric, ash damage, moreover it is possible to further in constraint cable
The structure in portion, has had this structure just, contrasts prior art, and the structure of the present invention is more reasonable, and cable is the most durable.
Preferably, outer belting layer is wrapped in by restrictive coating, restrictive coating be 125 DEG C of environmentally-friendly flame retardant thermoplastic elastomer TPE,
125 DEG C of environmental protection flame retardant crosslinked polyethylene XLPE, 150 DEG C of environmental protection flame retardant cross-linked polyolefin XLPO.Use this protective layer, the electricity made
Cable is more durable, also will not weaken the flexibility of cable while increasing service life.
The present invention is respectively coated with one layer of cable paper tape at conductor outer layer and woven outer layer, makes conductor and weaves more rounding, tight
Gather, can effectively avoid conductor loose or ellipse causes insulation or sheath thinnest point the thinnest, affect the high pressure resistant effect of cable.With
Time the present invention use aluminium-plastic tape is changed to extrusion molding semiconductive shielding layer to avoid this problem.The present invention has following master
Want advantage: soft, be easily bent, be more easy to construction；Big electric current high pressure resistant, resistance to；High temperature resistant；Resistant to liquid (gasoline, diesel oil, machine oil and
The various liquid of automotive interior) corrosion；Anti-electrical Interference is effective；Good flame retardation effect, use safer.The present invention and existing skill
Art is compared, and the adaptation ability in the presence of using screen layer to add its outside magnetic field, simultaneously because employ multi-layer cable paper tape
Structure, the structure of the cable being more rationally compacts, and owing to using six class conductor structures, therefore the present invention has more soft
Technique effect, substantially increase the pliability of whole cable, it is simple in the space that cable is narrow in car bending lay.
