[0002] Terminal blocks are solid devices composed of an insulating base and one or more live parts. Each conductive part can be used as a junction for connecting two or more conductors (wires), and also as a tool for connecting or disconnecting conductors (wires) individually. Terminal blocks are needed in the fields of automation control, control cabinet wiring, and data maintenance.

[0003] The terminal block distinguishes multiple terminals on the terminal block by setting patches of different colors on the surface, or setting numbers arranged in sequence, so as to realize the terminal block anti-wrong connection function. However, after the terminal female seat component and the terminal male seat component are plugged in, they are prone to looseness, resulting in poor consistency in the transmission of electrical signals. In view of this, we propose a terminal block with an anti-wrong connection function. Utility Model Content
