Terminal blocks are modular electrical connectors for reliable circuit interconnection, used to link wires with PCBs, equipment enclosures and standard DIN rails. Wires are fixed via screw clamp, spring push-in, pluggable, barrier or feed-through structures. Featuring insulation, high voltage resistance, anti-loosening and easy disassembly, they are widely adopted in industrial control, power supply, new energy, lighting and communication devices.
