The role of the junction box: In home decoration, the junction box is one of the electrical accessories, because the wires used for decoration pass through the wire tubes, and wiring is used at the joints of the wires (such as the lines are relatively long, or the wire tubes need to be turned). The box is used as a transition, the wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box to protect the wires and connect the wires.

Selection of junction box:

1. Determine the junction box model, name, logo, etc., and try to choose a big brand junction box, so that the quality and other aspects are more guaranteed.

2. Check whether the contact between the junction box and the network cable is even, whether there is an obvious gap, whether the connection is firm, and whether there is looseness. If the contact is poor, it will cause signal strength. Also pay attention to whether the socket socket is flush and whether the edges are No bulges, swelling or other problems.

3. The junction box must have a protective door, and the socket must have a certain width from the edge of the panel to ensure that a single pole of the plug cannot be inserted. Generally, the panel of a good quality junction box has a uniform color, good surface gloss, and no dents and other problems.

4. Pay attention to whether the panel and bottom plate of the junction box are firm and not loose, and whether the panel and bottom plate can be easily disassembled without tightness or difficulty in disassembly and assembly.
