Abstract: What is described is: a spring-loaded connection terminal (3) comprising a busbar piece (5) which has a base surface (6) and side walls (7) emerging laterally from the base surface (6). Mutually opposite side walls (7) delimit a receiving area (35) on both sides. The spring-loaded connection terminal (3) has a terminal arrangement for the terminal connection of an electrical conductor at an associated clamping point with at least one clamping spring (8), which is operatively connected to the busbar piece (5). At least one current bar (25, 25a, 25b) which is separate from the busbar piece (5) is introduced into the receiving area (35) of the busbar piece (5) and arranged in the receiving area (35) so as to form a clamping surface for the terminal connection of an electrical conductor.

Abstract: 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.

Abstract: A spring terminal element (1) is described, with a busbar piece (2), a tensioning bracket (3), which is mounted on the busbar piece (2) such that it can move relative to the busbar piece (2) and has at least one clamping edge (5a, 5b), which engages under the busbar piece (2), for clamping an electrical conductor between the clamping edge (5a, 5b) and the busbar piece (2), and a helical spring (8), which is operatively connected to the busbar piece (2) and to the tensioning bracket (3) and exerts a spring force between the tensioning bracket (3) and the busbar piece (2). An operating cylinder (10, 19) with a screw thread is mounted such that it can rotate and fixed in position in the extent direction of the operating cylinder (10, 19) on the tensioning bracket (3) or on the busbar piece (2). The operating cylinder (10, 19) is arranged with its screw thread (11) essentially in the internal area of the tensioning bracket (3), at least in the clamping state when it is clamped on an electrical conductor (L).
