Application scope and use of junction box

The plastic junction box is a device used for electrical connection and protection, usually used for the distribution, connection and terminal processing of electrical lines. It is made of insulating material, usually plastic, with good insulation performance, which can ensure the safety and reliability of electrical connection.

Scope of application:

Architectural field:
Junction boxes are widely used in lighting, electric power, fire protection and security systems in the building field.
In the electrical engineering of buildings, a large number of cables, wires and other circuits are usually connected in the junction box to realize the connection of wires and make the circuit system have certain functions.
Traffic field:
Junction boxes are often used to connect cables, wires and other equipment in the transportation field, such as trains, subways and other rail transit equipment.
It can also be connected with signal equipment and power supply equipment to ensure the efficient operation of traffic facilities.
Home decoration:
In home decoration, junction box is one of the electrical accessories, which is used for the transition of wire joints.
When the line is long or the conduit needs a corner, the conduit is connected with the junction box, and the wires in the conduit are connected in the junction box to protect and connect the wires.
Industrial automation control system：
Junction boxes are also used in industrial automation control systems, communication circuits, signal lamp control circuits, medical instrument circuits and other scenes.

The purpose of junction box：

Connecting wires:
The main function of the junction box is to connect wires and make the circuit system work normally.
Protect the wire:
The junction box can protect the wires from the external environment, such as dust and water.
Specific junction box types, such as splash-proof type and waterproof type, can also protect wires and circuits in specific environments.
Easy to maintain:
The use of junction boxes can reduce the connection points between cables and wires, which is more convenient for maintenance and management.
Transition:
In home decoration and other scenes, the junction box plays the role of wire joint transition, making the wire connection more standardized and safe.

Plastic junction boxes are widely used in buildings, factories, household electrical systems and various electrical and mechanical equipment, and are an important part of electrical connection and protection.
