  • the conductor terminal according to the invention in all the embodiments described additionally has an optimized overload protection to protect the clamping spring 5 in too inclined or otherwise improperly inserted conductor 8 in the conductor receiving chamber 60.
  • the clamp spring 5 must be protected from overstressing the second end portion 50 and the area extending from the second end portion 50 to the approximately half-round, along the wall 23 extending spring arc.
  • the clamping spring 5 extends with its second end portion 50 up to the chamfered portion 31 of the insulating material, which acts as a conductor insertion slope.
  • the running as part of the insulating housing 2 beveled portion 31 extends in the embodiment to below the upper portion 32 of the contact piece. This bevelled portion 31 thus acts at the same time as a stop for the second end portion 50 of the clamping spring 5, so that it can not be deflected further upwards.
  • the part of the contact piece 3, on which the actuating lever 7 is at least in the open position and possibly also other positions supported, in particular in positions before reaching the open position, can be formed as in the direction of rotation of the operating lever when opening rising ramp, sloping ramp or neutral surface without inclination.
  • the first and third embodiments of the terminal described above are in the form of a rising ramp, the second embodiment of a neutral area.
  • a sloping ramp can be realized by the upper portion 32 of the contact piece 3 not, as in FIG. 1 seen to the operating lever 7 towards the front of the terminal 1, that is formed to the side of the conductor insertion opening 6, rising, but with sloping slope.
