insertion and extraction life and mechanical performance

Test Background

AI servers require frequent maintenance, and quick connectors need to withstand thousands of insertion and extraction operations without failure. If the insertion and extraction force is too large, it will affect the operation experience. If it is too small, it may cause accidental disconnection. Mechanical performance is the key to user experience and safety.

Test Introduction

Through the insertion and extraction cycle test, insertion and extraction force/connection force test, and locking mechanism reliability test, verify the mechanical durability and operational convenience of quick connectors during long-term insertion and extraction use.

Testing Objectives

Verify that the seal and structure are intact after 5000 insertion and extraction cycles

The measured insertion force is ≤35N, and the extraction force is 15-45N

Ensure the locking mechanism is reliable to prevent accidental disconnection

Evaluate changes in mechanical properties during hot-plugging under pressure

FAQ
Q: Why is the insertion force required to be ≤ 35N?
A: To ensure that maintenance personnel can operate it easily with one hand and avoid pipeline shaking, or cold plate displacement caused by excessive insertion and extraction force.
