Description

TECHNICAL FIELD

[0002] In the field of power transmission and distribution, especially in application scenarios that need to handle large current loads, traditional connection methods often rely on ordinary cable lines. However, due to material and structural limitations, such cable lines generally have the technical shortcomings of large parasitic inductance and high hardness, which are not suitable for high-speed dynamic current, greatly limiting their application in high-speed dynamic current transmission scenarios.

[0003] For example, in the rapid charging system of electric vehicles, high-frequency inverter power supply, and dynamic power supply system of some automation equipment, the rapid change of current and dynamic adjustment of transmission path require the connecting wire harness not only to have high conductivity, but also to have good flexibility and durability. The hard wire characteristics of ordinary cable lines not only increase the complexity of installation, but also may cause damage to the insulation layer or internal conductor due to the inability to adapt to frequent bending and twisting, thereby affecting the stability and safety of current transmission.

[0004] Therefore, it is a technical problem to be solved to provide a soft and easy-to-install wire harness suitable for high-speed dynamic current scenarios, a new type of connecting wire harness that can not only meet the demand for large current transmission, but also has high flexibility and reliable insulation protection.
