Abstract

A cutting/clamping terminal element for electrical conductors (14) is disclosed including a clamping slot (0) defined between a clamping piece (4) and an elastic clamping leg (2,3; 23, 13) to ensure an improved contact connection, such that even conductors (14) having very thin conductor core diameters, in particular wire strands, can be connected, without the conductor cross section being reduced and without there being a risk of conductor breakage. For this purpose, the clamping piece (4) is provided with clamping legs (2,3; 12,13) arranged on its front and rear sides, said clamping legs overlapping in the position of rest the clamping piece (4) at least in part, such that the sharp edges (15,24) of the two clamping legs (2,3; 12,13) and of the clamping piece (4) cut into the insulation (11) and clamp the core (10) of the conductor (14) in the clamping slot (9) at in total three different positions.
