Definitions

  • the invention relates to a fuse link, in particular for low-voltage high-performance fuses, NH fuses, the working fuse by one display fuse element electrically arranged parallel to this is monitored by a signal element in a display device against the train through the display fuse element by means of a spring element is tensioned.
  • a fuse link is e.g. known from document DE-A-3 203 211.
  • Fuse inserts with a display device usually have a weakening of the body in the area of the display device of the fuse link.
  • the body's center indicator is in a critical area weakened.
  • They are designed as center indicators Display devices on the market with a Display pearl made of glass or plastic work.
  • the Display pearl is in one through the display fuse element Fixed recess in the body of the fuse link, where the fuse element is threaded through holes and on Contact plates or contact on the contact blades connected is. If the fuse element melts, the display bead is removed from the recess of the fuse body thrown out, causing the response of the Fuse link is displayed.
  • the falling out Display pearl and any necessary spring elements around the Ensure display function can fall in plants and Cause malfunctions or contamination.
  • the invention has for its object a fuse link to develop a clear display without falling parts and where the body through the Display device is not weakened.
  • Die Display device has a along the body of the Fuse insert sliding signal element on that in a field of vision when addressing the Display fuse element due to the striking design Indicates the response status of the working fuse.
  • the Signal element can be made of electrically non-conductive material be made so that protection against accidental contact is given is.
  • the viewing area can also be a recess or a viewing window be in a cover on the body surface. This mechanically protects the display device.
  • the signal element can also be recessed electrically conductive material. Independent of You can choose the material through a viewing area in a Cover particularly easily the visual conspicuity increase.
  • the field of vision can be easily carried out in the middle of the back of the body, so that the function of a center indicator is achieved is, without the weakening of the Body.
  • the signal element can be advantageously in the field of view in shifted condition so that it differs from its im
  • the color shown in the idle state differs in color, the distinguishing color also differs from the Color of the cover and / or the color of the body of the Melting insert stands out clearly.
  • FIG 2 is for the embodiment of FIG 1 View of the back of the fuse link with the Display device shown.
  • the fuse link according to FIG 1 is designed as a NH fuse and shown in longitudinal section.
  • the fuse link has a working fuse 1 and one electrically display fuse element 2 connected in parallel.
  • a Display device 3 includes a along the body 4 of the Melting insert displaceably guided signal element 5, the in a viewing area 6, see FIG 4, at Response of the display fuse element is shifted and through striking execution the response state of the Working fuse 1 shows.
  • the signal element 5 of the Display device 3 is against the train through the Display fuse element 2 by means of a spring element 7 curious; excited.
  • the spring element 7 is in the idle state under train through the fuse element 2 on the termination board 8.
  • the spring element 7 released so that the attached signal element 5 is moved under a cover 9. In a field of vision 6 then appears when the fuse element responds 2 the signal element 5 in a striking design.
  • the connection boards 8 can from Insulation material to be made. With such a It is executed for reasons of protection against accidental contact advantageous to electrically isolate the spring element 7 coat.
  • the signal element in Viewing area 6 designed in a band shape, the viewing area through a recess in the cover 9 on the body surface is formed.
  • the signal element points in the field of vision 6 in the shifted state a signal effect in that it is different from its shown in the visual range at rest Color differs, with the distinguishing color also on the color of the cover 9 and the color of the body 4 of the melt insert lifts off.
