Abstract: An electrical supply or connecting terminal with a clamping spring and a metal part, the clamping spring having a clamping leg and a contact leg, and the metal part having a conductor bar piece. The clamping leg and the conductor bar piece form a spring force clamp connection for the electrical conductor. The contact leg of the clamping spring has a recess for insertion of the electrical conductor, and an end of the clamping leg extends through the recess. The clamping spring has a retaining section which runs essentially parallel to the insertion direction of the electrical conductor and parallel to the conductor bar piece and the conductor bar piece has been inserted though the recess in a direction opposite the insertion direction of the electrical conductor, the conductor bar piece being clamped securely between the end of the clamping leg and the retaining section.

Abstract: A tension spring clamp assembly comprising: a housing (1) in which a tension spring (2) is attached by its bearing arm (3) to a power terminal (4) that protrudes through a clamping window (7) in a frontal section (6) of a spring arm (5) of the tension spring (2), and which is furnished with a conductor insertion aperture (8) below the power terminal (4) that in a clamped position faces an open area of the clamping window (7), and a test tap aperture (10) opposite an actuating aperture (9) allowing insertion of a contact pin (11 ) of a test plug (12) that contacts the power terminal (4). The test tap aperture (10) for insertion of the contact pin (11) is conformed as a hollow cylinder, wherein an extension of a cylinder axis (A) thereof extends along an inner side (13) of the bearing arm (3) that is facing away from the power terminal (4). An insertion aperture (14) for the contact pin (11) is also present in the frontal section (6) of the spring arm (5).

Abstract: Such a clamp has a clamping spring (5) and a busbar (4) on which the pretensioned clamping spring (5) can be placed. One end leg (8) of the clamping spring (5) has a window (9) penetrated by the tongue of the busbar (4), and a spring-tensioned electrical conductor can be fixed between a front edge (12) and the busbar (4). The other end section (14) of the clamping spring (5) abuts a brace of the busbar (4), and the spring forms a flexible joint (6) between its end leg (8) and the end section (14). To make the design and installation simpler, the clamping spring (5) is bent essentially in the form of a circular arc section at its flexible joint (6). Its end leg (8) and end section (14) are bent away from the open side (7) of the arc-shaped flexible joint (6), and the tongue (10) and brace (15) are in a respectively adapted position on the busbar (4).
