What is the power terminal
Power supply terminal block refers to the terminal block used on the drive power supply, while the widely used power supply terminal block is the fence type terminal block.
Classification of power terminals
Generally speaking, power terminals can be divided into four categories: 1. Plug in terminals are mostly used for controllers; 2. Direct welding terminal blocks are mostly used for system power supply and solar power supply; 3. Spring type terminal blocks are mostly used for rail transit and weak current system control; 4. Fence type terminal blocks are mostly used in fields such as control power supply of injection molding machines.
Fence type terminals are also called "American terminals" (Japanese terminals are also called black terminals because most of them are black), which are mainly composed of plastic shells, screws (including gaskets) and solder legs; Either single core wire or multi strand wire can be directly connected or connected with the end; The plate type crimping method is adopted, and the wiring is intuitive and firm, which is widely favored by customers.
The spacing between fence terminals is 6.35mm, 7.62mm, 8.25mm, 9.5mm, 10.0mm, 11.0mm and 13.0mm. Generally speaking, the greater the circuit current is, the greater the spacing between terminals will be, which can meet the requirements of various installation environments.
How to connect the power board terminal to the power line
1. In case of single connection and single switch, one terminal on the switch is connected to the live wire, one terminal is connected to the control wire, and the control wire is connected to the base of the lamp holder.
2. If it is a single double switch or triple switch, the grounding wire on the terminal shall be used as jumper to connect other terminals in the same row, and the remaining terminals shall be connected to the control wire (preferably separated by color wire), which shall be connected to the corresponding lamp base. After the switch is installed, the experiment shall be carried out. The principle is that the door shall be opened first and the rest shall be opened later. If the switch sequence is wrong, the control wire shall be adjusted. If the Owner requires otherwise, adjust the control line as required.
3. In case of single switch and double control, the single pole shall be connected to the live wire and control wire respectively, and the other two terminals in the switch box shall be connected to the two terminals in the other switch box with equal longitude wires.
4. For the socket with switch, just connect one end of the terminal in the switch to the live wire terminal, and allow the other terminal to connect it to the live wire terminal of the socket as a jumper.
