Process advantages

Precision welding technology: semi-automatic welding process is adopted, the diameter error of the welding spot is ≤0.05mm, ensuring extremely low contact resistance (＜1mΩ).

Ultrasonic sealing process: the shell is made of ABS material through 20kHz ultrasonic welding to form a molecular-level bond, and the airtight performance reaches 10kPa/min.

Error-proof design: the OBD interface adopts an asymmetric keyway design to 100% prevent mis-insertion; the terminal adopts a polarization design to ensure the only correct insertion direction.

Stress release structure: the joint between the wire and the connector adopts a tapered stress buffer design, and the bending resistance is ＞10,000 times.
