Main application fields

The application of terminal blocks is almost ubiquitous in all areas that require wiring. Here are some typical scenarios:

Industrial Automation and Control Systems

PLC control cabinet: As an intermediate connection point between the PLC input/output (I/O) module and field sensors (such as photoelectric switches, proximity switches), as well as actuators (such as solenoid valves, motor starters).

On-site equipment connection: Installed near motors, frequency converters, servo drives and other equipment on the production line, it is used for quick connection to power and control lines.

Distributed I/O system: As a component of the remote I/O station, it centrally connects a large number of field signal lines.

2. Building Automation and Intelligent Buildings

Illumination control system: It is used to connect and control the lighting circuits in different areas to achieve centralized management.

Security system: A node that provides power supply and signal connection for devices such as cameras, access control card readers, and alarm detectors.

Fire protection system: Connect smoke detectors, temperature detectors, manual alarm buttons, etc. The terminal box is required to have high reliability.

3. Energy and power industry

The photovoltaic junction box is a core component of the photovoltaic power generation system. It is responsible for collecting the current generated by the solar cells and outputting it, and also has the functions of lightning protection and diode protection.

Wind power generation system: It is used to connect various sensors and control systems inside the wind turbine nacelle.

Distribution box: In a low-voltage distribution system, it serves as a node for power input and the distribution of multiple branch outputs.

4. Transportation and Logistics

In the automotive industry, the junction box in the vehicle wiring harness is used to distribute power and protect circuits (integrating fuses and relays), serving as the "nerve center" of the entire vehicle's electrical system.

Rail transit: Electrical connections between train carriages and cable distribution for on-board control systems.

5. Infrastructure and Others

Telecommunication base station: used for the distribution of power lines and signal lines.

Outdoor lighting: Street lamps in parks and squares are usually equipped with waterproof and dustproof terminal boxes for cable connection.

Mechanical equipment: Inside almost all non-standard automated equipment and CNC machine tools, there are various types of terminal boxes of different specifications, which are used for the interconnection of electrical components.
