Abstract

The invention provides a temperature sensing cable for an automobile and a preparation method thereof. The temperature sensing cable for the automobile comprises a temperature sensing optical fiber, a soft copper conductor, a silicon rubber insulating layer, a graphene / activated carbon fiber cloth wrapping shielding layer, a sheath and an activated carbon fiber woven protective layer which are sequentially arranged from inside to outside. By adding the temperature sensing optical fiber, the cable can monitor the temperature of the cable and the connector at any time, and the safety of the new energy automobile is improved; and secondly, the graphene / activated carbon fiber cloth wrapping shielding layer and the activated carbon fiber woven protection layer are matched, so that the cable can adsorb peculiar smell and dust in the automobile and purify the environment in the automobile, the shielding performance and the heat conduction performance of the cable can be improved, and the finally obtained temperature sensing cable meets the design requirements of the new energy automobile.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a temperature-sensing cable for automobiles and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for the comfort, reliability and safety of cars are getting higher and higher. Good riding environment and safety warning system have become important symbols of modern cars. Concentration control improves the quality of the environment inside the car and ensures that drivers and passengers have a comfortable state and a happy mood. However, with the rapid development of new energy vehicles, spontaneous combustion incidents occur frequently, and the reliability and safety of new energy vehicles have become the focus of attention. [0003] CN210006534U discloses a heat dissipation cable for new energy vehicles, which includes an inner skeleton, a predetermined number of cable cores, an insul...
