[0002] Terminal blocks are accessories used to achieve electrical connections. In industry, they are classified as connectors. As industrial automation increases and industrial control requirements become more stringent and precise, the use of terminal blocks is gradually increasing. With the development of the electronics industry, the application scope of terminal blocks is expanding, and the types of terminal blocks are also increasing.

[0003] The assembly and maintenance of equipment require the use of a large number of terminals, which in turn require a large number of fixing screws and wire clamps during installation. This results in a waste of time during installation, and during long-term operation, safety accidents can easily occur due to loose screws.

[0004] To address the aforementioned issues, a press-fit type terminal block is proposed. Utility Model Content
