1. The wires in this area must be disassembled frequently due to factors such as adjustment and maintenance. For example, two wires that sometimes need to be connected and sometimes need to be disconnected can be connected with terminals and disconnected anytime and anywhere without the need to weld or coil them together, which is very time-saving and labor-saving.  

2. An electrical equipment box or circuit board, as a whole, must be electrically connected to other external power circuits. By using PCB wiring terminals on circuit boards, it is easy to detect wires in the event of common faults, without the time-consuming and laborious process of disassembling and assembling wires from the circuit board.  

3. The same equipotential point must be connected to a larger number of wires. There are holes on both sides of the terminal block for wires, screws for tightening or loosening, and suitable for interconnecting with many wires. In the power industry, there are specialized terminal blocks, terminal boxes, covered with terminal blocks, single-layer, double-layer, current, working voltage, general, breakable, etc.  

4. The cable diameter is very large, making it inconvenient to connect with screw terminals. Plug in terminal blocks use crimping frames for wiring, which can connect large cable diameters and protect wires from damage.  

5. The current is very high, and the contact area at the electrical connection must be increased. The TB series products' high current terminal blocks can meet the demand for high current connections.  

6. Multiple wires need to be connected to the same terminal. Because the same terminal block has multiple sockets for easy wire connection.  

It has been nearly a hundred years since the invention of self connecting terminals. From the earliest combination terminals to various plug-in, direct welding, fence, spring terminals, and even bare terminals, a sound electrical interface technology system has been formed in the connector industry. Its application scope has also expanded to several industries such as urban rail transit, intelligent security lighting fixtures, elevator car power engineering operation, medical equipment, etc., in various situations. Due to the convenient and stable electrical characteristics of wiring terminals, they are gradually gaining the trust of a large number of consumers.
