Abstract
A kind of new-energy automobile double shield high-tension cable, include conductor, insulating barrier, double shield and sheath, described double shield is made up of braid and aluminium plastic membrane layer, and described conductor, insulating barrier, braid, aluminium plastic membrane layer and sheath are radially arranged successively from inside to outside.The utility model adopts braid and the design of aluminium plastic membrane layer double shield structure between insulating barrier and sheath, the impact of the surrounding environment passed through vehicle when effectively eliminating and inhibit power cable to run and the electric/electronic device of vehicle itself, substantially increases the interference free performance of cable product; Adopt braid and the design of aluminium plastic membrane layer double shield structure, do not affect the flexible nature of cable product, bending techniques requirement when meeting product practical application.
Description
(1) technical field
The utility model relates to automobile cable technology, specifically uses double shield high-voltage power cable in a kind of new-energy automobile car.
(2) background technology
In high-flexibility anti-interference battery cable for new energy vehicle (patent No.: ZL200920256779.8), disclosed in the existing patents such as new-energy automobile motor cable (patent No.: ZL201220345244.X), new-energy automobile car inner high voltage power cable mostly adopts copper wire or tinned copper wire individual layer braid shielded structure, but in practical application, during new-energy automobile (comprising pure electric automobile and hybrid vehicle etc.) load running, start, braking, when accelerating and slow down, voltage, electric current and frequency all can change, in addition the voltage and current of new-energy automobile cable transmission is larger, so the electromagnetic interference produced is very large.The electric/electronic device of the surrounding environment that this interference can be passed through vehicle and vehicle itself has an impact, and vehicle even can be made normally not run.Automobile industry also strengthening the research and formulation that require the electromagnetic compatibility (EMC) of car load and automobile related components, proposes more and more higher requirement to the interference free performance of high-voltage power cable key components and parts especially.
In addition, in the structural design of disclosed new-energy automobile car inner high voltage cable, basic structure is conductor, insulation, proof copper-wire braided, sheath, in actual manufacture process, the process such as lousiness, meropodium silk of braiding is on the one hand bad, is easy to damage sheath, in addition, because sheath material characteristic determines squash type processing mode, sheath easily embeds braiding, brings in the high-voltage wiring harness course of processing and not easily opens the problems such as skin.
(3) summary of the invention
The technical problems to be solved in the utility model is to provide a kind of new-energy automobile double shield high-tension cable, substantially increase interference free performance and the safety in operation of cable, eliminate product electrical quality risk, ensure that the flexible nature of cable simultaneously, meet many technical requirements of products application.
For this reason, the utility model takes following technical scheme:
A kind of new-energy automobile double shield high-tension cable, include conductor, insulating barrier, double shield and sheath, described double shield is made up of braid and aluminium plastic membrane layer, and described conductor, insulating barrier, braid, aluminium plastic membrane layer and sheath are radially arranged successively from inside to outside.
Described conductor is annealing bare copper conductor or zinc-plated annealed copper conductor.
Described insulating barrier adopts thermoplastic elastomer (TPE) or thermo-setting elastomer, and insulation is closely extruded on conductor.
Described braid adopts tin-plating round copper wire or naked circular copper wire braiding composition, and braid closely covers the outer surface of insulation.
Described aluminium plastic membrane layer is close to the vertical bag of braid by single or double aluminum-plastic composite membrane or is wrappedly formed.
Described sheath adopts thermoplastic elastomer (TPE) or thermo-setting elastomer, and sheath is closely extruded on aluminium plastic membrane layer.
The utility model has the advantages that:
1, between insulating barrier and sheath, adopt braid and the design of aluminium plastic membrane layer double shield structure, the impact of the surrounding environment passed through vehicle when effectively eliminating and inhibit power cable to run and the electric/electronic device of vehicle itself, substantially increases the interference free performance of cable product; 2, adopt braid and the design of aluminium plastic membrane layer double shield structure, do not affect the flexible nature of cable product, bending techniques requirement when meeting product practical application; 3, between braid and sheath, adopt the vertical bag of aluminium plastic membrane or the design of lapping structure layer, eliminate the lousiness, meropodium silk etc. that weave in actual manufacture process to the damage of sheath and quality risk, improve the safety and stability of cable product electrical operation; Meanwhile, it also avoid sheathing and add and embed braided wires man-hour, excessive with braided wires cohesive force, thus cause high-voltage wiring harness to be processed not easily opening the problems such as skin.
(4) accompanying drawing explanation
Fig. 1 is the utility model structure cross-sectional schematic;
Wherein, 1-conductor, 2-insulating barrier, 3-braid, 4-aluminium plastic membrane layer, 5-sheath.
(5) specific embodiment
With reference to accompanying drawing 1, a kind of new-energy automobile double shield high-tension cable, include conductor 1, insulating barrier 2, double shield and sheath 5, described double shield is made up of braid 3 and aluminium plastic membrane layer 4, and described conductor, insulating barrier, braid, aluminium plastic membrane layer and sheath are radially arranged successively from inside to outside.The 6th class annealing bare copper conductor that described conductor 1 requires for meeting GB/T3956.Described insulating barrier 2 adopts TPE-S type thermoplastic elastomer (TPE), and insulating barrier 2 is closely extruded on conductor 1.Described braid 3 adopts the naked circular copper wire braiding composition meeting GB/T 3953 and specify, braid 3 closely covers the outer surface of insulating barrier 2.Count is not less than 80%.Described aluminium plastic membrane layer 4 is close to braid 3 by one side aluminum-plastic composite membrane and is indulged bag and form, and the vertical bag rate of putting up is not less than 15%.Described sheath 5 adopts TPE-S type thermoplastic elastomer (TPE), and sheath 5 is closely extruded on aluminium plastic membrane layer 4.
Have excellent interference free performance with double shield high-voltage power cable in the new-energy automobile car made in case study on implementation, shielding rejection coefficient is less than transfger impedance in 0.05,1-30MHz frequency range and is not more than 250m Ω/m.Product has good flexibility, and bending radius can reach the outside diameter of cable of 6 times.Electrical security and the stability of product are high.And eliminate high-voltage wiring harness processing and not easily open the problems such as skin.
