Description

Technical Field

[0001] The utility model relates to the technical field of terminal blocks, in particular to a cover plate for a terminal block row. Background Art

[0002] A terminal block is a fitting product used to achieve electrical connection and is classified as a connector in the industry. With the increasing industrial automation level and the more and more strict and precise industrial control requirements, the usage amount of terminal blocks is gradually increasing. With the development of the electronics industry, the application range of terminal blocks is getting wider and wider, and the types are also increasing. Besides PCB board terminals, the most widely used ones also include hardware terminals, nut terminals, spring terminals and so on.

[0003] After the terminal block is connected to the external wire, the connection part will be exposed to the air, which is likely to cause dust to fall on the connection part between the two. As the dust increases, a short circuit is likely to occur, and a cover plate is needed to block it. The existing cover plate structure is relatively complex. When installing, the wires on the terminal block row need to be removed, and then the wires are connected one by one after the installation is completed. It is easy to get confused when there are many wires, and it is more inconvenient to use. Content of the Utility Model
