AI Technical Summary
Existing male and female plug connectors use a stamping process, which results in insufficient roundness of the cross-section, uneven insertion, and deformation of the contact surface, affecting connection reliability and the stability of signal or current conduction.
The male and female plug-in assembly is precision machined using a CNC lathe, including a male connector, male pin, female connector, and female pin sleeve, ensuring the roundness of the parts. The plug-in connection between the male pin and the female pin sleeve, combined with the insulating sleeve and raised structure, improves the smoothness and reliability of the connection.
This solves the deformation problem caused by traditional stamping processes, making the insertion and removal contact between the female connector and the female insert cylinder smoother and more reliable, thus improving conduction stability and service life.
