Description

Technical Field

[0001] The utility model relates to the technology of cable field, in particular to an agricultural electric vehicle cable. Background Art

[0002] With the rapid development of social economy and the continuous improvement of people's living standards, the requirements for agricultural production efficiency and quality are getting higher and higher. In order to meet people's growing demand for agricultural products, agricultural production methods must be transformed into more efficient, environmentally friendly and sustainable forms. In this context, agricultural electric vehicles, as a new type of agricultural machinery, have received widespread attention.

[0003] Agricultural electric vehicles have been widely used in the agricultural field. They can replace human or animal power for agricultural handling operations, greatly reducing the physical labor intensity of farmers, reducing their labor burden and improving work efficiency. Moreover, agricultural electric vehicles are driven by electricity. Compared with traditional fuel vehicles, they have the advantages of zero emissions, low noise, and environmental protection. The use of agricultural electric vehicles can reduce pollutant emissions and improve the quality of rural environment. Therefore, in today's vigorous promotion of green agriculture, agricultural electric vehicles have become an important driving force for agricultural modernization.

[0004] There are many parts on agricultural electric vehicles, and many cables are used to connect different parts. At present, the cables used in agricultural electric vehicles generally include a core, an insulating layer, a shielding layer and an outer sheath. The insulating layer, the shielding layer and the outer sheath are sequentially coated on the outside of the core. The insulating layer, the shielding layer and the outer sheath are usually single-layer structures. Although the structure of this cable is relatively simple and can basically realize the signal transmission function, its function is relatively single and the structural design is not reasonable. The agricultural electric vehicle will vibrate a lot when in use. The buffering performance and shock resistance of the current cable are not good. Excessive vibration will affect the transmission of the signal and even damage the internal structure of the cable. The service life of the product is short; secondly, the tensile strength of the cable is not good, and it is easy to break when subjected to external impact, which brings inconvenience to the user; and the waterproof performance of the cable is poor, and it is easy to short-circuit due to external water immersion, which has a large safety hazard and cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current agricultural electric vehicle cables. Utility Model Content
