Definitions

  • the invention relates to a fuse link, in particular for low voltage high power fuses, too NH fuses called, the working fuse by one display fuse element electrically arranged parallel to this is monitored.
  • the display fuse element stops Spring element tensioned in front of a circuit board.
  • the spring element is also slidable along the body of the fuse link led signal element connected in one Field of vision when the fuse element responds striking design the response state of the working fuse displays.
  • Such a fuse link is known (DE-U-2 97 18230).
  • Fuse inserts with a display device usually have a weakening of the body in the area of the display device of the fuse link. Especially with so-called The body's center indicator is in a critical area weakened.
  • the fuse link mentioned above a Weakening can be avoided in that the signal element largely on the back of the fuse link and not is guided in a tunnel of the housing body.
  • the signal element however, it is conveniently provided by a cover protected and if necessary also managed.
  • connection of the movable signal element that consists of a film can be made with the spring element that can also be used as a so-called front indicator can is not straightforward in practice. Glue, warm emboss, crimp, connect with shrink wrap have become shown in practice as expensive.
  • the invention has for its object a fuse link the described type to develop further and with regard the connection of the signal element with the spring element to improve:
  • the described task is solved by a fuse link according to claim 1.
  • the signal element is here executed as a film in a transition area to Spring element is narrower than in the field of vision; in a head area for attachment to the spring element is outgoing of a greater width of the head than it is Has passage opening in the board, the signal element tapered to a tip. Through the tip, the signal element inserted into the through opening of the board in the transition to the larger width of the head area bevels are formed that are film-like Material formed signal element roll up, so that first an assembly position can be reached and later the signal element can be pulled out of the board.
  • the narrow transition area between the viewing area and the head area can run in the lead-through opening of the board and the viewing area takes place in front of the board or in front of one Insulation or sealing layer a stop.
  • the wide head area allows using conventional techniques such as those above are described, the signal element with the spring element connect.
  • the signal element in its head area in a transition to the taper area at least a more tapered ramp on.
  • the signal element is carried out the board facilitated by its constructive training.
  • the spring element has one free cut mandrel on, against the pulling direction of the signal element is flipped.
  • This mandrel can become a spring element be placed vertically, whereupon the film-like signal element can be pressed so that the thorn pierces and his undercuts the signal element without additional fasteners hold.
  • the signal element be obtained by section from an endless belt.
  • the fuse link according to FIG 2 has a working fuse 1 with two opposing knife contacts 2 more common kind of. Electrically parallel to the working fuse a display fuse element 3 is arranged, which is a spring element 4 holds tensioned on one of two boards 5. The boards have usual grip tabs in the upper area.
  • the Spring element is in Figure 2 in addition to its rest position illustrated in the sprung state.
  • a signal element 7 is displaceable guided.
  • a viewing area 8 it shows when the Display fuse element 3 and spring deflection of the spring element 4 conspicuous execution in a display area 9 for addressed Fuse when moving out that fuse has addressed. Because of the usual vote of Display fuse element to the working fuse element is then namely the working fuse melted and has the The fuse is switched off.
  • the signal element 7 is of a cover 10 covered by it on the back of the body 6 of the fuse link can be performed.
  • the signal element 7 can also have a flat guide groove in the body 6 for that Display element may be formed so that the cover then only covers the signal element to the outside.
  • the signal element 7 is designed according to FIG 1 as a film in a transition area 11 to the spring element narrower than in Viewing area 12 is executed.
  • a head area 13 for Attaching to the spring element 4 is the signal element 7 to one Tapered tip.
  • the head area 13 starts from a larger one Width as its opening 14 in the board 5th has from.
  • the spring element 4 can on the knife contact 2 in a manner known per se.
  • the signal element points in a transition to the tapered area 7 according to FIG. 1 two bevels 15 in which the head area tapers more than in its other lacy Education. This promotes curling up when Insertion into the feedthrough opening 14.
  • the spring element 4 in the development according to FIG 3 has one cut-out mandrel 16 on the fully assembled Fuse is flipped.
  • Figure 3 is the spring element 4 shown as it can be made.
  • the cushioning of the spring element 4 when addressed Display fuse element 3 can be influenced favorably.
  • the mandrel 16 can be bent out of the plane of the drawing and then flipped over in the pulling direction of the spring element be, so that it points opposite to FIG 3. at mentally opposite direction of pull of the signal element in other words, the mandrel 16 is then against the direction of pull of the signal element flipped.
  • the signal element 7 can be cut by section from an endless belt be won.
  • the mandrel 16 has an undercut, as shown in 3 is illustrated, holds the pressed signal element even behind the head of the mandrel 16 even before the flip of the thorn.
  • a wide head region 13 of the signal element 7 can use conventional fastening techniques to connect the Signal element can be used with the spring element 4.
  • the head area overall can also be made narrower. In each In this case, the signal element is connected without play 7 with the spring element 4.
  • the signal element can Made of polyethylene, elastic and tear-resistant his.
