Definitions

  • the present invention relates to a Miniature circuit breaker for interrupting a circuit when a predetermined current is exceeded.
  • Circuit breakers are known for example from DE 195 03 530 A1.
  • On such circuit breaker as shown in Fig. 5 is composed of two half-shells Switch housing, a switching mechanism, a Contact device, a magnetic release, a switching and Extinguishing chamber as well as a thermal trigger.
  • the Switching of this circuit breaker is internal either via the magnetic release or the thermal Triggers when the specified current is exceeded triggered.
  • the switching process can also be done by a external signal are triggered.
  • a external signal can also be done by a external signal.
  • the switch housing in the swivel range of a release lever of the switching mechanism an elongated hole.
  • a pen can go through this slot through into a recess or hole in the Engage the release lever.
  • circuit breaker can be arranged exactly next to each other, and that circuit breaker of the same type are used, i.e. that the swivel axes and the cutouts of the release levers of the individual circuit breakers are arranged concentrically to each other.
  • the object of the invention is to create a innovative circuit breaker, in which the constructive design of the signal transmission means is improved.
  • the first release lever serves the internal one Trip of the circuit breaker while the second trip lever at least for external triggering.
  • the provision of the second release lever increases the Design freedom regarding the arrangement of the Access opening for the signal transmission pin.
  • different circuit breakers can be operatively coupled become, i.e. for example circuit breakers, their swivel axis of the first release lever is not arranged concentrically.
  • Fig. 1 shows a circuit breaker according to the invention in partially cut condition.
  • Fig. 2 shows a detailed view of a lever arrangement of the Circuit breaker shown in Fig. 1, a first Release lever is not yet installed.
  • Fig. 3 shows the detailed view of Fig. 2 after the Installation of the first release lever.
  • Fig. 4 shows a top view of a second Release lever.
  • Fig. 5 shows a conventional circuit breaker in partially cut condition.
  • the circuit breaker has one of two half shells composite switch housing 1, a switching mechanism 2, a contact device 3 for producing the electrical Connection or to disconnect the electrical connection in the circuit to be protected, a magnetic release 4 for electromagnetic triggering of the switching process, a switching and Arcing chamber 5 and a thermal trigger 6 for thermal triggering of the switching process.
  • the circuit breaker is switched on via the switching mechanism 2. switched off. This is done manually by swiveling a hand control lever or toggle 2.4.
  • the pivoting of the Hand control lever 2.4 actuates the Contact device 3 via a knee joint lever 2.3 and an actuation of a first release lever 2.1 via a Gear mechanism (not shown).
  • a second release lever 2.6 through the first release lever 2.1 actuated.
  • circuit breaker can be operated by an external Signal are triggered. This process is referenced on Fig. 2 to 4 explained in more detail.
  • An external signal is transmitted through a Switch housing 1 provided slot (not shown) via a provided in the second release lever 2.6 Recess or hole 2.9 in the second release lever 2.6 initiated.
  • a pen (not shown) through the slot of the housing 1 with the recess 2.9 are engaged.
  • the by the external signal in the second release lever 2.6 initiated force causes Swiveling the second release lever 2.6 around his Swivel axis fixed to the housing 2.7.
  • the contour of the second release lever 2.6 to the housing contour adjusted that the ingress of dust particles into the Switch housing 1 is prevented.
  • the circuit breaker according to the invention makes it possible to Circuit breakers of different types, i.e. with different arranged trigger axis, in a group next to each other to arrange a simultaneous triggering of the entire Switch group due to the tripping of a single circuit breaker to effect. That is, during the first release lever with regard to its shape and its pivot point on the housing adapted to the switching mechanism of the respective circuit breaker must be the articulation point as well as the shape of the second preferably lever-shaped trigger means arbitrarily and thus be uniform for all circuit breaker types.
  • the second trigger means 2.6 does not necessarily have to Have the shape of a lever, but can also be another Be gear element with which a pivoting movement of the first Trigger means 2.1 in a substantially linear movement (also corresponds to a circular movement with a large radius) one Transfer pin is converted.
  • a rack, a crank / connecting rod assembly and the like conceivable.
  • the invention is not limited to the bilateral Signal transmission limited. Rather, it can be executed in such a way that a signal is only one-sided is transmitted, e.g. only from the inside of the circuit breaker, but not the other way round, or from the inside out, but not the other way around. This can be done, for example that the driver pin 2.8 of the second release lever 2.6 only on one side of the cam 2.5 of the first Trigger lever 2.1 is applied while the game on the other Side is so large that signal transmission is effective is prevented.
  • the circuit breaker according to the invention has the two release levers to trigger the switching process.
  • the first release lever 2.1 is used to trigger the switching process due to an internal signal, such as from a Bimetal as the thermal release 6 or the Magnetic release 4.
  • the second release lever 2.6 is used Triggering the switching process due to an external signal, for example one from another circuit breaker signal transmitted via a signal transmission pin.
  • the both release levers are via the gear mechanism, preferably consisting of the cam 2.5 and the Driving pin 2.8 and / or other gear elements such as Gears, connecting rods, etc. are operatively coupled.
