A cable connector is a waterproof connector that can be used underwater without affecting its performance. There are many manufacturers of waterproof joints, and some well-known brands, but which one is better, this is more difficult to judge. Therefore, when you buy waterproof joints, you must learn how to judge the waterproof strength of the waterproof joints, so that you can buy quality products.
    I don't know if you noticed it. Generally, there is a string of numbers on the description of the waterproof connector. The larger the number, the stronger the waterproof ability of the connector. This can be used as a reference for everyone when purchasing waterproof connectors. This number is a two-digit number that represents the different parameters of the waterproof connector. The first digit is from 0 to 6, which represents the ability of the cable connector to protect against solids. The higher the value, the stronger the protection. If it is 0, it means there is no protection at all.
    The second digit indicates the ability to protect against water. This value is from 0 up to 8 and is the same as the ability to prevent solids. The greater the value of the second digit, the proportional change in protection. 0 means no water resistance at all, the same as non-waterproof products, if you want to buy waterproof products, the latter value is 0, you can not buy. On the other hand, if it is the maximum value of 8, it means that the ability to waterproof is very strong, and it can be used for a certain period of time under water without any problem. Of course, if it is not for professional needs, there is no need to buy such a good waterproof connector, because the price is still relatively expensive.
