1. What is a fence terminal block?
A fence terminal block is a commonly used electrical connection device, mainly used to connect wires or conductors to a circuit. It usually consists of a plastic or metal shell and multiple metal terminals, each of which has a pressure plate or screw that can clamp the wire or conductor to connect it safely and firmly to the circuit.

2. What are the uses of terminals?
Terminal blocks have a variety of uses in electrical connections and are widely used in various electrical equipment and systems.
Main uses
Distribution boxes and control cabinets: In distribution equipment and control cabinets, terminals are used to connect power supplies, loads and various control devices to form electrical control loops.
Home appliances: In home appliances such as air conditioners and refrigerators, terminals are used to connect power lines to ensure the normal operation of equipment.
Industrial equipment: In various types of automation equipment, sensors and actuators, terminals are used to transmit signals and power to ensure precise control.
Power supply system of buildings: In the power supply system of buildings, terminals are used to connect cables to ensure the safety and stability of power supply.
Automotive electrical system: In a car, the terminal block is used to connect batteries, control modules, lights and other electrical equipment to ensure the normal operation of the overall electrical system.

3. What is a three-way terminal block?
A three-way terminal block is a device with three terminals, usually used to connect three different circuits or signals. This type of terminal is usually used in situations where multiple signals or power supplies need to be processed simultaneously, such as sensors, control circuits, etc.
Structure and function
Three-way terminal blocks usually have three independent terminals, each of which can connect different circuits or signals. These terminals usually have identification to facilitate users to distinguish and connect different lines. For example, the upper wiring position can connect the signal line of the sensor, and the bottom and middle layers can connect the positive and negative power lines of the sensor respectively.

4. What is the difference between a junction box and a terminal block?
There are significant differences between junction boxes and terminal blocks in structure, function and use.
Structural differences
The junction box is usually composed of a housing, a terminal board, an isolation board, etc. The structure is relatively complex and the design is compact. It can save space and prevent problems such as short circuits and circuit failures. The terminal block is composed of a cable, a conductor, a connector, etc. The structure is relatively simple and is mainly used for circuit connection of multiple wires.
Functional differences
The main functions of the junction box include branch connection, protection, isolation and fixation of the circuit, and are often used in lighting, electricity, communications and other fields. The terminal block focuses more on the circuit connection of multiple wires, and is usually used in automation control, power distribution, electronic communications and other fields. It can quickly complete the circuit connection and improve work efficiency.
