[0002] Terminal blocks are an electrical accessory product that is mainly used to achieve electrical connections. They are designed to connect and disconnect wires quickly and easily, ensuring a safe, stable and easy-to-maintain electrical connection between wires. Terminal blocks have a variety of forms and structures in different applications. Terminal blocks are widely used in industrial automation equipment, control systems, household appliances, building wiring and other fields. With the development of technology and changes in demand, the types and functions of terminal blocks are also continuously increasing and improving.

[0003] Some terminal blocks are designed without full consideration of the actual installation environment and operating space. For example, the terminal spacing is too small, the fixing screw position is not conducive to tool operation, etc., which makes it difficult for tools to accurately and conveniently access the wiring parts when disassembling and installing wires, or the operator's fingers cannot move flexibly, increasing the risk of misoperation. Therefore, we hope to design a terminal block with a new structure to solve this problem. Utility Model Content
