We all use plastic waterproof junction boxes during line construction. They are widely used due to their excellent waterproof capabilities and material characteristics. Today, let's introduce in detail how plastic waterproof junction boxes achieve waterproofing and how to install them specifically.

  How do plastic waterproof junction boxes achieve waterproofing?

  The raw materials of waterproof junction boxes mainly include five categories: stainless steel, ABS engineering plastic, polycarbonate (PC), glass fiber reinforced polyester, and PC/ABS. Among these materials, plastic waterproof junction boxes have the best waterproof effect. In addition to the material, the waterproof performance also depends on the design structure. A reasonable structure can improve its waterproof performance, making it able to waterproof well even in heavy rain. Moreover, the waterproof device using silicone sealing rings can improve the waterproof performance by five times.

  How to install plastic waterproof junction boxes?

  First, thread the cable into the bottom shell. After stripping the cable, pull it back and tighten the waterproof connector housing clockwise. Strip about 2 cm of the wire, then complete the wiring as needed. Then cover the terminal cover, then the inner cover, and finally tighten the outer cover clockwise. This way, the outer cover will fit closely with the bottom shell.
