Terminal blocks are modular, insulated bases used to connect wires, printed circuit boards, and other electronic components to one another. Terminal blocks consist of an insulating body and a clamping device.
Based on the application, a terminal block may be designed to accept clips, stripped wires, plugs or other specialized connectors. Wires and other components can be affixed to terminal blocks through soldering, screws, clamps, tabs, tabular screws and plugs.
