Waterproof joints, as the name suggests, can be applied to the water environment, providing safe and reliable connector joints. For example: LED street lights, lighthouses, cruise ships, industrial equipment, sprinkler and so on, all need to use waterproof joints.
At present, the main evaluation criteria for waterproof performance of waterproof connectors are based on the IP waterproof grade standard. To see how the waterproof joint waterproof performance, mainly to see the IPXX behind the two digit XX, the first X is from 0 to 6, the highest level is 6; second digits from 0 to 8, the highest level is 8; therefore the highest waterproof grade of joints is IP68.
Refer to general is waterproof connector and waterproof box supporting the use of this type of junction box is generally called the joint waterproof box or terminal waterproof box, depending on how much the hole we have one into one, one in two out to a waterproof box more into consideration, which includes the following:
1. waterproof connector is usually installed into the plastic waterproof box side, so for the opening of the requirements is to achieve the external thread dimensions of the joint can be.
2. consider wiring and opening. At least one in and out, this involves at least two waterproof connectors and two box wall openings, so make sure the size and location of the opening and the size of the waterproof joint.
3. whether the junction box, terminal or other electrical components, must through the waterproof joint to wiring, guarantee waterproof performance.
