  1. Screw connection: This method uses screw terminals to connect wires. It is important to consider the maximum and minimum wire cross-sections allowed, as well as the maximum torque for different screw sizes.2. Soldering connection: The most common soldering method is tin soldering. It is essential to ensure that a continuous metal connection is formed between the solder material and the surface being soldered. Different types of soldering connections include solder tab style, eyelet solder tab style, and arc notch solder tab style.3. Crimp connection: Crimping is a technique where metal is compressed and displaced within specified limits to connect wires to contact pairs. Good crimp connections can produce metal intermolecular flow, resulting in symmetrical deformation of the wire and contact material. This type of connection is similar to cold welding and can withstand harsh environmental conditions.4. Wrapping connection: Wrapping involves wrapping the wire directly around the angular contact pillar. The wire is wrapped, pressed, and fixed at the angular contact pillar to create a sealed contact.

  When using PCB terminal blocks for wiring applications, it is important to keep in mind the following precautions:1. Always ensure that the power is switched off before starting any wiring operations. Never attempt to work on the terminal blocks while they are live. If you are unsure whether the power is off, use a voltage tester to verify. Additionally, if there are sliding buttons on the terminal blocks or switches, it is advisable to replace them if they are worn out to prevent any risk of electric shock.2. When connecting to the power source, make sure to install PVC conduit for wire routing. Avoid leaving wires hanging loosely without any proper support or fixation on support brackets or busbars.3. Pay attention to the length of the wires when connecting to the switch box. It is recommended to keep the wire lengths within a suitable range and properly route them through conduits. Avoid pushing the wires directly into the switches for fixing.By following these precautions, you can ensure safe and efficient operation of the PCB terminal blocks.
