A positionable screw terminal and its connecting device

This utility model relates to the field of terminal block technology and discloses a positionable screw terminal, including a wiring portion and a conductive plate fixed to the lower side of one end of the wiring portion. A copper post is installed through one end of the conductive plate, and a fastening component is embedded in the front side of the wiring portion. A positionable screw terminal connection device includes a rubber plate and a circuit board, which are connected by the positionable screw terminal. This utility model overcomes the problems of inaccurate positioning, misalignment, jamming, and slippage when installing screw terminals on circuit boards by assembling guide chamfers, assembling positioning steps, and interference straight hobbing teeth for installation. The pressure plate in the fastening component squeezes the wire inside the wiring portion, making the wire more securely fixed without deforming the wiring portion. When inspecting or replacing the wire, there is no need to replace the screw terminal. The positioning hook and positioning step make the installation of the screw terminal to the rubber plate and circuit board simpler and more secure.
