Mechanical properties areWaterproof connectorAn important performance of, mainly including five types: mechanical lifespan, positioning keys, locking, vibration resistance, and impact resistance. Below is a detailed introduction of these five types.

1. The mechanical life is actually a durability indicator of waterproof connectors. The mechanical life of waterproof connectors is determined by one insertion and one extraction as a cycle, and is evaluated based on whether the connection can be completed without errors after the predetermined insertion and extraction cycle

2. The function of the positioning key is to prevent the use of waterproof connector key structures due to incorrect insertion during use.

3. Locking is a special safe and reliable connection method used to prevent accidental separation of waterproof connectors caused by vibration, thus solving problems such as waterproofing. When threaded connections are made, the connector is equipped with a safety fuse.

4. Vibration and impact resistance are one of the main mechanical properties of waterproof connectors, which are very important in practical application cases and are generally applied in fields such as aerospace, railway, aviation, and road transportation.
