Definitions

  • the invention relates to a low-voltage high-performance fuse, hereinafter referred to as an NH fuse, with a display device in the manner of spring plate indicators, the fuse element attached to a circuit board being passed through the other circuit board. is guided through and fastened to a spring plate under pretension, so that the spring plate changes its position as a visual display when it melts.
  • a NH fuse is e.g. known from FR-E-93 779.
  • spring plate indicators have the advantage over the usual pin indicators that they are more economical to manufacture and assemble.
  • the invention has for its object to develop a NH fuse with a particularly reliable spring plate indicator, which can also be installed particularly economically.
  • the spring plate is formed from two superimposed legs, a base leg and a narrower display leg, which are arched together, that slots are formed in the curvature up to the flat legs and in the leg ends and that the display fuse element is fastened to the inside of the display leg and is guided outwards through the slot in the arch and is passed through a hole in the other board at the slot in the leg ends.
  • An NH fuse with such a spring plate indicator ensures, on the one hand, for mechanical reasons and, on the other hand, due to the resulting strain relief of the fuse element through the special guidance on the spring plate indicator, a reliable indication of whether the fuse has blown. Since no parts can fall off the indicator when the fuse responds, such an NH fuse is also particularly reliable when used in systems.
  • the slot at the end of the leg of the indicator leg serves to guide and secure the position of the indicator fuse element.
  • a further development of the NH fuse is that rivets are embossed from the board that carries the spring leaf indicator, which are matched to rivet holes in the base leg in such a way that the inner end of the slot in the base leg has a wide through hole in the board almost up to the Diameter of the fuse element covers. This eliminates the otherwise necessary separate sealing of the through hole in the board that carries the spring leaf indicator.
  • Such through holes can not be made arbitrarily fine because of the material thickness of the board and it must be avoided that sand the Lösch spalluhg the NH fuse is lost from the through hole.
  • the spring plate indicator thus also serves to seal the through hole. It is advantageous if the inner end of the slot in the base leg is tapered in a V-shape with a small curve.
  • the switching state of the fuse is indicated by a display device consisting of a spring plate indicator 4 and a fuse element 5.
  • the display fuse element 5 is clamped to the circuit board 6 by a sleeve 7, which at the same time closes the filling opening for the quenching sand in a conventional manner.
  • the display fuse element is passed through the other circuit board 8 through a through hole 9 and fastened to one leg of the spring plate indicator 4.
  • FIG. 2 consists of a spring plate, which forms two superimposed legs, a base leg 10 and a display leg 11. Both legs, as can be seen more clearly from FIG. 3, are connected to one another by a curvature 12. 2, the display leg 11 is narrower than the base leg 10. A slot 13 is formed in the arch 12 up to the flat legs. Likewise, slots 14 and 15 are formed in the leg ends, which are aligned at their roots in the assembled state.
  • the display fuse element 5 is welded to the inside of the display leg 11, guided outwards through the slot 13 and passed through the through hole 9 through the slots 15 and 14 in the leg ends.
  • assembly begins more expediently 4, which is clamped through the through hole 9 after the display fuse element 5 has been passed through.
  • rivet holes 16 are formed in the base leg, compare FIGS. 2 and 6.
  • rivets 17 can be embossed from the board 8, which carries the spring plate indicator 4, as shown in FIG. 8.
  • the inner end of the slot tapers in a V-shape in the base leg and is designed with a small rounding, as shown in FIG. 6.
