Abstract
The utility model relates to a special cable used for electric and signal transmission in application of new energy vehicles. A technical problem solved is that aimed at defects in the prior art, the cable suitable to be used in the electric vehicles is developed, and requirements of electric drive is satisfied. The cable should satisfy large current and high voltage, and has good electromagnetic shielding performance, relatively good flexibility, and impact resistance and vibration resistance. The high voltage cable used for electric vehicles is a multiple core cable. Core wires are formed by inner conductors and core wire insulating layers. An outermost layer is an outer sheath. The cable is characterized in that after multiple cores of the core wires are stranded, a first shielding layer formed by wrapping an aluminum plastic composite film and a second shielding layer formed by weaving tinned wires. Preferably, the insulating layers of the core wires and the outer sheath are silicone rubber. The high voltage cable used for electric vehicles made according to the above can satisfy application requirements of large current and high voltage, and has good electromagnetic shielding performance, impact resistance, vibration resistance, and good flexibility.
Description
Technical field
The utility model relates to cable, relates in particular to be the applied special cable in order to electric power and signal transmission of new-energy automobile.
Technical background
After country advocates energy-saving and emission-reduction energetically, all actively developing new-energy automobile both at home and abroad, because new-energy automobile is pure driven by power, require different with traditional fuel-engined vehicle, traditional automotive line only has good environment resistant and mechanical performance, but but be difficult to satisfy the use of electric automobile, power-jdriven gear needs cable to have properties such as big electric current, high voltage.Be badly in need of the special cable with above-mentioned premium properties that research and development can be applicable to new-energy automobile at present.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, develops the cable that is suitable on the electric automobile, satisfies power-actuated performance need.Cable will satisfy big electric current, high voltage, good capability of electromagnetic shielding, shock-resistant, vibration resistance, flexibility.
For solving the problems of the technologies described above, technical solution of the present utility model is:
The used for electric vehicle high-tension cable is multicore cable, and heart yearn is made of inner wire and core insulation layer, and outermost layer is oversheath; It is characterized in that: after described heart yearn multicore is stranded, be provided with successively by the wrapped ground floor screen that forms of plastic-aluminum combined film and the second layer screen that formed by tinned wird braiding at its skin.
Preferably, described core insulation layer is silicon rubber.
Preferably, described oversheath is silicon rubber.
The utility model can bring following beneficial effect:
The utility model adopts plastic-aluminum combined film and tinned copper wire braiding dual shield, makes it to have advantages of favorable electromagnetic shielding effect, from the mechanical performance of structure and technology assurance cable.The utility model heart yearn adopts silicon rubber as its insulating material, guarantee electrical property and the environmental performance of cable from material, silicon rubber has good flexibility, electric property and weatherability, the long-term work temperature can reach 180 ℃, it is the highest that withstand voltage to reach the general automotive line of 600V(can only be withstand voltage following to 60V), maximum rated operating current reaches 600A, guarantees the safe transmission of cable signal and electric energy under various environment.
The used for electric vehicle high-tension cable of making according to the utility model satisfies big electric current, high-tension application needs, has good capability of electromagnetic shielding, and shock-resistant, vibration resistance, flexibility are good.
Description of drawings
Fig. 1: the construction of cable schematic diagram of a preferred embodiment of the present utility model;
Fig. 2: the making flow chart of a preferred embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1,1 is inner wire (the tinned wird specification is 37/0.23) among the figure; 2 is core insulation layer (silicon rubber, external diameter 2.9mm); 3 is ground floor screen (plastic-aluminum combined film is wrapped); 4 is second layer screen (tinned wird braiding); 5 is oversheath (silicon rubber, external diameter 10.8mm).
Present embodiment uses silicon rubber as cable core insulation and oversheath, guarantees higher electrical property, weatherability and the flexibility of cable; Use plastic-aluminum combined film and tinned copper wire braiding dual shield, reach good shield effectiveness.The requirement on electric performance of every core can reach: insulation resistance 〉=10
12Ω, D.C. resistance≤11.7 Ω/km; Environmental performance can reach: serviceability temperature-40 ℃～180 ℃.
The manufacturing process of this preferred embodiment is as follows:
Tinned wird was stranded before this, extruded silicone rubber insulation layer simultaneously outside the inner wire of the stranded formation of tinned wird; The heart yearn that adopts above-mentioned steps to make is carried out the stranded and wrapped plastic-aluminum combined film of four-core form the ground floor screen, adopt the tinned wird braiding to form second layer screen again, adopt silicon rubber to extrude the formation oversheath at last.
