Why Waterproof Junction Boxes Are Waterproof？

Why waterproof junction boxes are waterproof:

First of all, this junction box should be waterproof, and its material should be waterproof. At present, the most common materials with better waterproof effect are plastic, rubber, metal and other materials. For the junction box, metal is obviously unrealistic, mainly because the metal is a conductor, and using it as a material for the junction box can easily lead to leakage accidents. Rubber is easy to age and difficult to form, so in addition to the selection of materials, it is its design structure. The structure is the key factor restricting its waterproof effect. A reasonable structure design can effectively avoid water caused by various situations.

Waterproof junction boxes are generally used together with waterproof joints and waterproof junction boxes. According to the number of openings, we have one in and one out, one in and two out to one in and more out of the waterproof box, which includes the following considerations:

1. The waterproof joint is generally installed on one wall of the plastic waterproof box, so the requirement for opening the hole is to meet the external thread size of the joint.

2. Consider that the wiring and openings are at least one in and one out. This involves at least two waterproof connectors and two openings on the box wall, so be sure to figure out the size and location of the openings and the correct waterproof connector size.

3. Regardless of the terminals in the junction box or other electrical components, they must be wired through waterproof connectors to ensure waterproof performance.

There is also a silicone sealing ring in the box, so that the lid and the box are tightly sealed, which greatly improves the waterproof performance of the box.
