For the junction box, the metal is obviously unrealistic. The main reason is that the metal is a conductor. Using it as a junction box to make materials is likely to cause a leakage accident. The rubber is easy to age and is not easy to form. Therefore, in addition to the choice of materials, its design structure, the structure is the key factor that restricts its waterproof effect, and the reasonable structural design can effectively avoid the water caused by various conditions.
The waterproof junction box is generally used with waterproof joints and waterproof junction boxes. According to the number of holes, we have one in and one out, one in and two out to one in and 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 the opening is to reach the external thread size of the joint.
2. Consider wiring and opening at least one in and one out. This involves at least two waterproof joints and two opening holes in the box wall, so be sure to find out the size and position of the opening and the size of the waterproof joint.
