Description

Technical Field

[0001] The present invention relates to the technical field of automobile connectors, and in particular to a new energy automobile connector that is easy to connect. Background Art

[0002] New energy vehicles are clean energy vehicles powered by unconventional automotive fuels and integrating advanced power control and drive technologies. They encompass technologies such as pure electric, plug-in hybrid, and fuel cell vehicles. Their core feature is the replacement of traditional internal combustion engines with electric motors to achieve zero-emission or low-emission driving. They also leverage cutting-edge technologies such as battery management systems and intelligent networking to reshape the vehicle's energy supply and interaction model. As the "nerve hub" of new energy vehicle power transmission systems, new energy vehicle connectors play a crucial role in the overall vehicle architecture. They must not only carry the stable transmission of high voltage and high current, but also ensure secure interconnection between the signal control unit and core modules such as the power battery, drive motor, and charging port under complex operating conditions. Their reliability is directly related to the stability of the vehicle's power transmission system.

[0003] The new energy vehicle connection devices in the existing technology generally adopt a mechanical connection structure of male and female plug-in. Its axial holding force mainly depends on the static friction resistance generated by the mating interface between the two. This traditional design scheme can meet the basic conductivity requirements under static working conditions, but in actual applications, that is, when the male head undergoes periodic plugging and unplugging operations, the contact surfaces of the male and female terminals will produce slight wear, resulting in nonlinear attenuation of the actual contact area, causing an exponential increase in contact impedance, which can easily lead to abnormal temperature rise, signal transmission distortion and other electrical performance degradation phenomena. In extreme cases, it may even cause unexpected interruption of the power circuit. For this reason, a new energy vehicle connector that is easy to connect is provided. Summary of the Invention
