Spring terminal element and terminal block

摘要

A spring terminal element, with a tensioning bracket mounted on a busbar piece such that it can move relative to the busbar piece has at least one clamping edge which engages under the busbar piece for clamping an electrical conductor between the clamping edge and the busbar piece and a helical spring which is operatively connected to the busbar piece and to the tensioning bracket. An operating cylinder can rotate and be fixed in position in the direction of the operating cylinder on the tensioning bracket or on the busbar piece. The screw thread on the operating cylinder engages with a screw thread on an operating section which is coupled to the tensioning bracket or to the busbar piece in order to move the tensioning bracket relative to the busbar piece during rotation of the operating cylinder.
