Spring clamp connection and conductor connection terminal

Abstract

Spring-loaded clamping connection with at least one busbar (3) and at least one clamping spring (4) fixed to the busbar (3) by means of a positive and / or force-fit connection, the clamping spring having a clamping leg (43) for clamping an electrical conductor to at least one contact section (31, 32) of the busbar (3), wherein an electrical conductor inserted in a conductor insertion direction (L1, L2) can be clamped to the at least one contact section (31, 32) by means of the clamping leg (43) by means of spring force, wherein the busbar (3) has a retaining opening (33) and the clamping spring (4) has a retaining section (44) which projects through the retaining opening (33) of the busbar (3), characterized in that the retaining opening (33) has a width in a through-hole area (35) which is greater than the width of at least the part of the retaining section (44) projecting through the retaining opening (33) of the busbar (3).and the width of the retaining opening (33) decreases in the direction of the at least one contact section (31, 32).
