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 are the alternatives to the terminal block?
The main alternatives to the terminal block are as follows:
Wire plug: A wire plug can be used instead of a terminal block. Cut a small section of the end of the wire and insert the wire plug into it. It should be noted that the wire plug needs to be selected to match the cross-sectional size of the wire, and it must be stable after insertion.
Insulating tape: Insulating tape can be used instead of a terminal block. Cut a small section of the end of the wire and cross its center line together, then wrap the wire end with insulating tape until the end of the wire covers the insulating tape. It should be noted that the tape needs to be tightly wrapped around the wire.
Wire twister: If a more professional method is needed, a wire twister can be used. Peel the wire, bend the staggered middle part and then weld it below. Hold the shell left and right to connect the wires firmly. It should be noted that welding needs to be done correctly to prevent the interface from loosening and causing electrical failure.
Pressure-free quick wiring terminal: For example, the pressure-free quick wiring terminal tool-free direct plug-in terminal block KV2.5 replaces the UK/ST/PT rail type, the pressure-free quick wiring terminal tool-free direct plug-in terminal block, etc. These products do not require tools to install and are suitable for alternative use in emergency situations.
PCB male and female butt plug-in terminal block: For example, the PCB male and female butt plug-in terminal block 15EDGK-3.5/3.81KA/KB replaces the Machiyo Gaozheng. This terminal block has a plug-in function, which is convenient for connection and disconnection.

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.
