In home decoration, the junction box is one of the electrical accessories, because the wires used for decoration pass through the wire tube, and the junction box is used as a transition at the joint part of the wire (for example, the line is relatively long, or the wire tube needs to be cornered) Use, 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. This is the junction box.
Generally, the junction box is composed of a box cover, a box body, a terminal, a diode, a connecting wire, and a connector.
The requirements for use are as follows:
1) The shell must have strong anti-aging and ultraviolet resistance;
2) Meet the requirements for use under harsh outdoor environmental conditions;
3) The self-locking function makes the connection method more convenient and firm;
4) It must have a waterproof seal design, scientific anti-shock insulation protection, and better safety performance;
5) The wiring terminal should be installed firmly and have good weldability with the bus;
6) The main function of the diode is the one-way conduction function;
7) Connectors and connecting wires: with good insulation performance, male and female plugs with self-locking function make the solar panel and electrical connection more convenient and reliable.
Installation of junction box
Installation of wire box under cast-in-situ floor
For the installation of the junction box under the cast-in-situ floor, there are three installation methods: set terminal junction box connection, set intermediate junction box connection, and set branch line box connection. Among them, the terminal connection method has only one outlet, while the indirect method has two outlets, and there are 4 outlets in the branch box connection.
The junction box is installed on the beam side
The junction box is installed on the beam side, and the cables need to be bound on the steel bars when entering the floor.
The junction box is installed in the wall
The cables also need to be bound and fixed after they are led out from the junction box.
