Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a insert structure on a terminal block. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections, and are classified as connectors in industry. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising. As the electronics industry develops, the application range of terminal blocks is expanding, and the types are also increasing. Besides PCB board terminals, the most widely used types include metal terminals, nut terminals, spring terminals, and so on.

[0003] Existing terminal blocks typically consist of a plastic base, a set of long pins, and a set of short pins. The installation process involves inserting the long pins and short pins into the plastic base. Potential risks associated with this installation method include:

[0004] 1. Due to the negligence of the installer, the installation was not in place, and the long and short pins were not well fixed on the plastic part holder. During subsequent transportation and use, the long and short pins were prone to falling or shaking due to poor stability, which led to poor contact of the PCB board and affected the use of electrical components.

[0005] 2. The top of the long needle is completely exposed, which can easily lead to bending or pressure on the needle body during transportation and installation due to external forces, resulting in problems such as the needle body being unable to make normal electrical connections.
