Definitions

  • the invention relates to a connection terminal for electrical switching devices the preamble of claim 1.
  • Such an exclusion clamp is from the Document DE-U-94 06 108 known.
  • connection terminals Essentially two different types are known. Depending on the material used, these clamps are designed with closed clamp frames in a first embodiment and with open clamp frames in a second embodiment.
  • clamp frames in an open embodiment increased demands are to be made of the material to be used with regard to the tensile strength (Rm) and the yield strength (Rp 0.2 ). The requirements are varied. On the one hand, a certain strength of the clamping frame is required so that it does not plastically deform under load, and on the other hand, the material must be sufficiently soft so that it can still be processed as well as possible (especially punching and bending).
  • Known clamping frames only partially meet these requirements.
  • the invention is therefore based on the object of having a connecting terminal to create a particularly open clip frame that the previously mentioned requirements better than conventional Clamping frame.
  • the clamping frame 2 made of a non-magnetizable steel, in Form of a chrome-nickel alloy with an austenitic structure.
  • the Distribution of chromium and nickel within the alloy is chosen so that after work hardening of the material by cold working, this remains non-magnetizable. For this the material becomes like this cold worked that a cross-sectional decrease of 15-20%, preferably 17%, is reached (Fig. 3).
  • FIG. 2 shows the mass content diagram of a particularly preferred material.
  • This is the material with the steel key number 1.4571 (DIN 17007). After a special work hardening, this material fully fulfills the requirements of the invention.
  • the chrome-nickel alloy has the greatest possible distance from the line to the transformation of austenite (not magnetizable) into ferrite or martensite (both magnetizable) with the highest possible proportion of nickel. This distance to the transformation line is required so that no strain of martensite or ferrite is produced during work hardening by cold working, which would then make the material magnetizable. Exactly this magnetizability should be avoided in any case in order to keep the self-heating of the connection terminal which occurs due to eddy current losses as low as possible.
  • this steel is not an expensive custom-made product but a standard steel.
  • this steel is strain hardened to a certain extent in order to obtain the desired properties for the clamping frame according to the invention.
  • the steel is cold worked, for example by rolling or drawing, in such a way that the steel has a cross-sectional decrease of 15% -20%.
  • FIG. 3 shows the tensile strength (Rm / N / mm 2 ), the yield strength (Rp 0.2 / N / mm 2 ) and the elongation at break (A b /%) as a function of the decrease in cross section of the steel 1.4571. It can be seen from this that the desired properties are achieved with a cross-sectional decrease of the above-mentioned material by 15% -20%.
  • a steel treated in this way has a tensile strength of 700-800 N / mm 2 and an elastic limit of 600-700 N / mm 2 .
  • the present invention includes all described in claims 2 to 5 Embodiments.
