Definitions

  • the invention relates to an overvoltage protection element according to the Preamble of claim 1
  • Surge protection elements used to the appropriate Twin wires before overvoltages and currents due to technical Defects or external faults such as To protect lightning strikes.
  • surge protection elements have a voltage-limiting and usually also a current-limiting component on which a Melting element, usually in the form of a solder pill, is assigned. Occurs in the voltage-limiting component for a long time Overcurrent, the solder pill melts due to the occurring Heat loss from the component, which usually means a mechanical fail-safe shorts the lines to earth. This is necessary because of the resulting overcurrents the components and their immediate surroundings functionality may have been impaired.
  • Various optical fail-safe signaling known for example, LEDs are used.
  • the spring-loaded Plug the fail-safe contact onto the surge arrester which is to be used one via a melting element and the other directly with one Center electrode of the surge arrester is connected.
  • the center electrode is also permanently connected to the via a solder joint Earth potential connected, so that the fail-safe contact is also permanent is connected to the earth potential.
  • the fail-safe contact formed with a clamp that, for example, in a circuit board is insertable. The clamping causes an adjustment between Surge arrester and fail-safe contact or signaling contact and surge arrester.
  • the signaling contact is in the same Direction like the fail-safe contact is spring-loaded and lies over one insulating film on the melting element.
  • the signaling contact is below the melting element with a hook-shaped bulge formed, the when melting the melting element Signaling contact below the insulating film electrically with the Fail-safe contact and thus connected to the earth potential. This will the electrical circuit of the fail-safe signaling is closed, and for example an LED starts to light up.
  • This well known Surge protection element has some disadvantages.
  • the Surge arrester and fail-safe contact are in balance, that is disturbed by the additional bias of the signaling contact is so that the surge arrester can be displaced under load can.
  • Another problem is the complex manufacture of the insulating Foil for the signaling contact.
  • the positioning between the surge arrester and the fail-safe contact via the Clamping or between fail-safe contact and signaling contact quite complex and prone to errors, since only an exact relative movement between fail-safe contact and signaling contact an error-free Signaling guaranteed.
  • the invention is therefore based on the technical problem Surge protection element with direct signaling to create that is easier to manufacture and position and is reliable Signaling realized, as well as to create a fail-safe contact for such an overvoltage protection element can be used.
  • a fusing element is placed on the insulating parts of the Surge arrester arranged and the signaling contact permanently electrically connected to the fail-safe contact. This eliminates the difficult to set relative movement between fail-safe contact and signaling contact. Another advantage is that the Signaling contact no insulating film or the like is required.
  • the permanent connection between fail-safe contact and signaling contact by a resilient bias of the Signaling contact against the fail-safe contact can be realized nevertheless the problem of displacement of the surge arrester prevent since the bias of the signaling contact is not in the must be in the same direction as the fail-safe contact, as long as only it is ensured that the two are permanently electrically connected, so that the bias of the signaling contact is not that Balance on the surge conductor disturbs so that it does not displace can be.
  • clamping can also be dispensed with what simplifies manufacture and positioning. Then kick one longer-term overvoltage, the melting element melts, and the Shorting bar short-circuits the electrodes of the surge arrester. At the same time, the fail-safe contact touches the center electrode and is thereby connected to the earth potential.
  • the fail-safe contact is on another side of the shorting bar Melting element designed with an associated earth contact. At the When the melting elements melt, the earth contact contacts the Center contact of the surge arrester safely before the shorting bar shorts the electrodes. This will always counter the electrodes Earth shorted.
  • the melting elements designed as a solder bridge. This allows the fail-safe contact to move smoothly, so that the two electrodes are safe at the same time be short-circuited.
  • the fail-safe contact is in the middle area formed with support elements, which preferably from the Fail-safe contact are cut out.
  • the support elements prevent the fail-safe contact is pushed too far onto the surge arrester is and acts like an adjustment element that ensures the safe contact of Guaranteed solder bridge and surge arrester.
  • the longitudinal dimensions are of the fail-safe contact in the middle area is equal to that of the Surge arrester, which allows simplified visual control, whether the fail-safe contact is symmetrical on the surge arrester is postponed and a simple shift of the fail-safe contact prevented ..
  • the overvoltage protection element 1 comprises one Surge arrester 2, a fail-safe contact 3, a fusible element 4 and a signaling contact 5.
  • a center electrode of the Surge arrester 2 is permanently connected to a solder joint 6 Earth rail 7 connected.
  • the melting element 4 is also with the Center electrode of the surge arrester 2 connected.
  • About the Fusible element 4 is therefore also permanently in contact with fail-safe contact 3 Ground.
  • Part of the fail-safe contact 3 is in the earth rail 7 introduced and forms a clamping 8.
  • the signaling contact 5 is arranged on a circuit board 9 and is part of a Signaling circuit.
  • the signaling contact 5 is like the fail-safe contact 3 spring-loaded and in the area of the melting element 4 electrically by means of an insulating film against the melting element 4 isolated.
  • the signaling contact 5 is like the fail-safe contact 3 spring-loaded and in the area of the melting element 4 electrically by means of an insulating film against the melting element 4 isolated.
  • Surge protection element 1 is the principle of the invention Surge protection element 1 shown.
  • As in the prior art 5 is the center electrode of the surge arrester 2 for example via a solder joint 6 permanently with the earth rail 7 connected.
  • the fail-safe contact 3 is spring-loaded on the Surge arrester 2 snapped open.
  • the fuse element 4 connected to the fail-safe contact 3 but not with the center electrode of the surge arrester 2 connected, but lies on the isolated areas of the Surge arrester 2 between the electrodes.
  • the Signaling contact 5 is resilient in the direction of the printed circuit board 9 preloaded and electrically connected to fail-safe contact 3.
  • Another advantage is that the Force of the signaling contact 5 on the surge arrester 2 in is substantially perpendicular to the earth rail 7, so that no displacement of the Surge arrester 2 takes place. At this point, only one more time expressly noted that, if necessary, even on one Biasing of the signaling contact 5 can be omitted, as long as it is only ensured that despite a movement of the fail-safe contact 3 this permanently with the signaling contact 5 electrically stays connected.
  • the fail-safe contact 3 comprises a short-circuit area 11, a middle one Area 12 and an earth contact area 13 and is made of one strip-shaped, resilient, electrically conductive material in the form of a open ring trained.
  • the fail-safe contact is in the short-circuit area 11 3 formed with a shorting bar 14, the thermal Overload the two electrodes 15, 16 of the surge arrester 2 short circuit.
  • the associated with the shorting bar 14 Melting elements 4 is in the form of a solder bridge, which on the insulated areas 17 next to the center electrode 18 on the Surge arrester 2 rests.
  • the fail-safe contact is in the earth contact area 13 3 with an earth contact 19 in the area of the center electrode 18 formed, the earth contact 19 preferably by a suitable Free cut is realized.
  • the earth contact 19 is also a solder bridge trained melting element 20 associated, which also on the isolated Areas 17 rests.
  • the fail-safe contact 3 is in the middle region 12
  • Support elements 21 formed, which in the snapped-out state on the isolated areas 17 of the surge arrester 2 and can also be realized with free cuts. The support elements effect an adjustment of the solder bridges so that they are not on the center electrode 18th come to rest.
  • the melting elements 4, 20 begin to melt what a movement of the fail-safe contact 3 in Earth contact area 13 and in the short-circuit area 11 results. by virtue of the inward formation of the earth contact 19 touches it first the center electrode 18 so that the fail-safe contact 3 is at ground potential lies. When melting further, the shorting bar 14 then touches the two electrodes 15, 16 and closes lines connected to them against earth briefly. This ensures that the lines are always against Earth short-circuited.
  • the melting elements 4, 20 as solder bridges ensures that even with only one-sided Overvoltage, for example on the a line, both electrodes 15, 16 and thus the a and b lines are safely short-circuited to earth, because due to the heat conduction, the melting element 4, 20 melts completely.
  • the central area 12 is the longitudinal dimension of the fail-safe contact 3 equal to that of the surge arrester 2, which is a simple optical Control of proper snapping enabled.
