AI Technical Summary
Traditional AB glue sealing is prone to cracking and sealing failure, affecting the accuracy of lithium battery testing, and the aging of the glue leads to inaccurate test results.
The pneumatic connector body with threaded part is used to achieve double sealing by combining the first sealing ring and the second sealing ring. It can be quickly installed with the battery housing through the internal thread, and the sealing ring is provided with sealing protrusion and anti-dislodgement groove to improve the sealing effect.
It enables rapid sealing installation of the pneumatic connector and the battery casing, avoiding problems such as seal failure and colloid aging, and improving testing accuracy and reliability.
