The Necessity of Waterproof Connectors

Definition and function of waterproof connector

Waterproof connector is an electronic component with waterproof function for working in water. Power cords, network cables, etc. can be placed inside it. Not only can it provide normal and safe and reliable power supply and signal transmission, the most important role is to have a good waterproof and dustproof effect.

At present, the main assessment standard for the waterproof performance of waterproof connectors is based on the IP waterproof rating standard.
The waterproof performance of the waterproof connector mainly depends on the two digits XX behind the IPXX. The first digit X is from 0 to 6, and the highest grade is 6; the second digit is from 0 to 8, and the highest grade is 8. Therefore, the highest waterproof grade of the waterproof joint is IP68.

Why are waterproof connectors so widely used?

With the development of technology, the use of electricity is everywhere. However, there are certain hidden safety hazards to live things, so waterproofing is very important. The waterproof connector can enter the environment with water because it has excellent sealing performance and reliable waterproof performance. For example, if some equipment needs to enter the water or be installed underwater, using a waterproof connector can eliminate the problem of damage to the equipment due to water entering the connector (especially water containing more chemical substances).

The emergence of waterproof connectors can be said to be a great boon. It has a wide range of applications, and waterproof connectors are needed in many fields. For example, in the industrial environment, LED lighting, urban outdoor lighting projects, lighthouses, cruise ships, aviation, industrial equipment, cables, sprinklers, etc., all need to use waterproof connectors. In the military field, due to stricter application requirements, a large number of waterproof connectors are used, such as connectors for submarines and connectors for submarine-launched missiles.
