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).
