With the rapid advancement of technology in today’s society, mechanical equipment has become increasingly sophisticated. These advanced machines reflect a clear trend: they are capable of replacing more and more manual labor. It’s evident that high-tech mechanical equipment plays an essential role in modern society. Among these machines, there is a small yet crucial component that should not be overlooked—the connector.

Compared to other industrial connectors, waterproof connectors are particularly important in any environment where water is present or there is a risk of exposure to moisture. So, what are the two key aspects to consider when evaluating a high-quality waterproof connector? Beyond its fundamental waterproof function, special attention must be paid to its mechanical performance—specifically insertion and extraction force—and its environmental adaptability.

First and foremost, the insertion and extraction forces of a waterproof connector must comply with industry standards. If the insertion force is too high, it can lead to difficulties during installation. Over time, this may introduce potential safety hazards to the entire mechanical system.

On the other hand, the extraction force should be relatively higher. If it is too low, the connector may easily become disconnected after installation. This not only shortens the service life of the connector but also poses significant safety risks to the connected equipment—especially since waterproof connectors are often used in environments where exposure to water is likely. If the connector fails, allowing water to reach the equipment, the consequences could be severe.

Secondly, it is crucial to consider the operating environment when selecting a waterproof connector. The connector’s temperature and humidity ratings must exceed those of the equipment it serves. A high-quality waterproof connector should perform reliably within its specified temperature range without degradation of components or performance.

High humidity can compromise the insulation properties of the connector, so it’s important to ensure that the operating environment does not exceed the connector’s humidity resistance. Additionally, resistance to shock, vibration, and compression is critical—particularly in industries such as aerospace, railway, and road transport. The connector must be robust enough to withstand harsh conditions and maintain stable performance under significant mechanical stress.

No matter where the waterproof connector is used, it is essential to choose the appropriate protection level to avoid unnecessary complications in the future.
