Problems solved by technology

[0002] The outer sheath material of the wiring harness is used to protect the wiring harness. It should have certain wear resistance, corrosion resistance and mechanical properties. The car USB2.0 connection harness is usually bent and wound due to frequent use and small space in the car. Therefore, in addition to wear-resistant and corrosion-resistant properties, the vehicle-mounted USB2.0 connection harness also needs to have good resistance to bending and deformation. However, the current vehicle-mounted USB2.0 connection harness is resistant to wear, corrosion, bending, The resistance to deformation can not be well balanced, therefore, it is necessary to provide a new outer sheath material for the flex-resistant automotive USB2.0 connection harness

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a flexure-resistant vehicle USB2.0 connection harness outer sheath material. Background technique [0002] The outer sheath material of the wiring harness is used to protect the wiring harness. It should have certain wear resistance, corrosion resistance and mechanical properties. The car USB2.0 connection harness is usually bent and wound due to frequent use and small space in the car. Therefore, in addition to wear-resistant and corrosion-resistant properties, the vehicle-mounted USB2.0 connection harness also needs to have good resistance to bending and deformation. However, the current vehicle-mounted USB2.0 connection harness is resistant to wear, corrosion, bending, The anti-deformation performance cannot be well balanced. Therefore, it is necessary to provide a new outer sheath material for the flex-resistant in-vehicle USB2.0 connection harness. Contents of the invention...
