How to quickly determine the performance of waterproof connectors

Many things in life will use electricity, but the charged things will have certain dangers, and the waterproof connector can avoid this danger very well. It has excellent sealing performance and reliable waterproof performance. For example, if some equipment is to enter the water or be installed underwater, then use waterproof connectors to avoid the problem of damage to the mechanical equipment due to the entry of water, especially water containing more chemical substances.
At present, there are many brands and types of waterproof connectors on the market, but there are still not many connectors with excellent sealing and waterproof performance in the true sense. Therefore, all waterproof connectors should undergo rigorous waterproof test experiments when they leave the factory. It is best to put the connector in a water depth of 10 meters to work for 2 weeks, or put it in a water depth of 100 meters to work for 12 hours. If it can still maintain good working performance, then it is a pass.
A major advantage of waterproof connectors is that they are waterproof, so that the connectors can be used in a wider range of harsh working environments. Generally, there are two types of waterproof connectors: ①The design process is waterproof; ②The connector has a matching waterproof plug/block, which plays a waterproof role.
To see the waterproof performance of the waterproof connector, it mainly depends on the two digits XX at the back of IPXX. The first X is from 0 to 6, and the level is as high as 6. The second digit is from 0 to 8, and the level is as high as 8. Therefore, the waterproof connector The waterproof rating is up to IP68. Sealing principle: Rely on up to 5 sealing rings and sealing rings to pre-tighten the seal with pressure. This kind of seal will not lose the pre-tightening force when the connector expands and shrinks, and the waterproof effect is guaranteed for a long time. Water molecules cannot penetrate under ordinary pressure. (It can work for a long time at a water depth of less than 2-5m) IP68 , The first digit "0~6" indicates the dustproof level, and the last digit "0~8" indicates the waterproof level.

The above is an introduction to the waterproof level of the connector. I believe that after reading it, you must have a deeper understanding.
