Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vehicle harness, especially CCS vehicle harness. BACKGROUND

[0002] In the modern automobile industry, with the rapid development of electronic technology, the electrical system of the vehicle becomes more and more complex. In order to ensure the efficient operation and safety of the system, the International Organization for Standardization has developed a series of strict electrical connection standards, of which the most important is the CCS harness standard. CCS, which stands for Car Connector System, is a connection solution specially designed for automobile electrical systems. It aims to provide a universal and efficient electrical connection interface, so that automobile components produced by different manufacturers can be seamlessly connected, reducing the failure rate and improving the overall performance and reliability of the vehicle.

[0003] At the same time, with the development of automobile electrification, the demand for lightweight and low-carbon of automobile harness is increasing. In order to better reduce the carbon emission cost of automobile harness without reducing its electrical performance, smaller design of wire specifications, and newer metal compatible wires are generated. The amount of 0.35 square CCS harness accounts for about 50% of the total low-voltage harness, and the wire length accounts for more than 70%. The current automobile harness signal line and most low-power harness use 0.35 square copper wire. This specification is too redundant for signal line and low-power harness design. If a smaller square specification wire is used, the mechanical strength is lower, resulting in shorter service life of the harness. SUMMARY

[0009] Further, in order to make the copper wires uniformly distributed in the space between the copper layer and the insulating layer in the circumferential direction, 6 to 12 copper wires are uniformly distributed on the outer side of the copper layer in the circumferential direction.

[0010] Further, in order to make the copper wires uniformly distributed in the space between the copper layer and the insulating layer in the circumferential direction while being able to use copper wires of appropriate specifications, 8 copper wires are uniformly distributed on the outer side of the copper layer in the circumferential direction.

[0011] Further, in order to reduce the design redundancy of large-specification wires for signal lines and low-power wire harnesses, the wire is a 0.19 square wire.

[0012] Further, the wire is connected with a connector one through a crimping mode.

[0013] Further, the end of the wire is connected with a connector two and / or a connector three through an ultrasonic wave or a crimping mode.

[0014] Further, a fixing member is arranged on the wire for fixing on a vehicle body.

[0015] Further, the fixing member is a PA material or a metal material, and is a clamping nail and / or a support and / or a wire slot.
