First of all, this kind of junction box must have a waterproof effect, and its manufacturing material should have a waterproof effect. At present, the waterproof effect of our common materials is mainly plastic, rubber, metal and other materials. For the junction box, metal is obviously unrealistic. The main thing is that metal is a conductor. Using it as a material for the junction box can easily lead to leakage accidents. The rubber is prone to aging and not easy to form, so there is only one functional requirement of the
Plastic Waterproof Junction Enclosure.
In addition to the choice of materials, there is another point in its design structure. The structure is a key factor restricting its waterproof effect. A reasonable structure design can effectively avoid rainwater caused by various wind directions. There is also an efficient waterproof setting with a silicone seal ring, which can increase the waterproof performance by 5 times.
