Motor lead for new energy pure electric vehicle

Abstract

The invention discloses a motor lead for a new energy pure electric vehicle, and belongs to the technical field of electric wires and cables. The motor lead comprises a cable core, isolation paper and an outer sheath, wherein the isolation paper is extruded outside the cable core, and the outer sheath is positioned outside the isolation paper. A signal cable core and a group of power leads are stranded to form the cable core, the signal cable core comprises a group of signal wire cores, a filler strip, a lapping layer, a braided layer, an inner sheath and a ground wire, a coating layer is extruded on each signal wire core, the filler strip is positioned in the middle of the signal wire cores, the lapping layer laps outside the signal wire cores, the braided layer and the inner sheath are sequentially arranged outside the lapping layer from inside to outside, the ground wire is positioned between the lapping layer and the braided layer, the outer sheath is a soft polyether type polyurethane sheath, and the inner sheath is a thin-walled polyester elastic body. The motor lead has the advantages that the motor lead is better in scouring abrasion resistance, greasy dirt resistance and flexibility, vibration of the inside cable core can be decreased, the signal cable core can be individually protected in an enhanced manner and separated from the power leads, interference caused by external electromagnetic waves can be prevented, and adaptability to service environments is effectively reflected.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, and in particular relates to a motor lead wire for a new energy pure electric vehicle. Background technique [0002] At present, more than 95% of the power of motor vehicles comes from oil and gas, and oil and gas are non-renewable energy sources. With the intensification of use and dependence, the withering phenomenon is becoming more and more serious, and will cause serious environmental pollution. Due to the depletion of oil resources and the improvement of environmental protection requirements, new energy vehicles will surely become the mainstream of vehicle development. The new energy vehicles mentioned above refer to vehicles that use non-conventional vehicle fuels other than gasoline and diesel as the power source and have advanced drive and control technologies. According to different power sources, they can be divided into three categories: 1. Hybrid vehicles (full name in Eng...

Problems solved by technology

The reported motor cables for new energy pure electric vehicles widely use soft PVC (polyvinyl chloride) materials as insulating layers or sheaths. The disadvantages are: 1. Adhesion is prone to occur at high temperatures and the service life is short; Poor performance, easy to crack when exposed to oil, and low reliability for long-term use; 3. The softness is not high, and it is not convenient for vehicle wiring
