Definitions

  • the invention relates to an electronic circuit breaker.
  • a circuit breaker serves to automatically open an electrical load circuit upon the occurrence of a trip condition, i. to interrupt electrically.
  • the tripping condition is usually an overcurrent (short circuit or overload).
  • a circuit breaker may also be set up to trip at a different trip condition, in particular an under or overvoltage.
  • Thermal circuit breakers In classic electrical circuit breakers, the presence of the tripping condition is detected by a thermal and / or magnetic action principle.
  • Thermal circuit breakers usually comprise a tripping element in the form of a load current flowing through the bimetal or wire, the thermally induced change in shape triggers the circuit breaker.
  • tripping In the case of magnetic circuit breakers, tripping usually takes place by direct energization of a magnet coil by the load current itself.
  • An electrical overcurrent circuit breaker with a thermal tripping principle for example, is off EP 0 616 347 B1 known.
  • Another electrical circuit breaker with an additional undervoltage release is off EP 0 802 552 B1 known.
  • the trigger condition in an electronic circuit breaker is detected by an electronic circuit.
  • the trip electronics upon detection of the trip condition, generate a trip signal, which in turn is used to actuate, e.g. magnetic trigger leads.
  • An electronic circuit breaker usually consists of a large number of individual parts. For this reason, it is often only comparatively large in volume. On the other hand, an electronic circuit breaker is often comparatively expensive to assemble.
  • An electronic circuit breaker according to the preamble of claim 1 is made US 2004/251994 A known.
  • an electronic trip unit and an electromagnetic tripping unit are accommodated separately from the switching contact in a housing, wherein the two tripping units act in parallel to each other via a triggering mechanism on the switching contact.
  • the invention has for its object to provide a compact and easy to install electronic circuit breaker.
  • the circuit breaker comprises an insulating housing, a switch contact for reversible contact closure, ie opening and closing a load circuit to be monitored, a release magnet, which acts on the switching contact via a trigger mechanism, and a triggering electronics for controlling the trigger magnet.
  • the switching contact, the trigger magnet and the triggering electronics are firmly mounted on a common circuit board.
  • the printed circuit board thus forms a pre-assembly, which can be used as intended outside the circuit breaker housing and in the course of the final assembly of the circuit breaker as a whole in the housing. Due to the pre-assembly of the switch contact, the release magnet and the triggering electronics on the common printed circuit board assembly costs of the circuit breaker is greatly simplified overall.
  • circuit board with the components to be mounted on it outside the circuit breaker housing is much more accessible than in the installed state, whereby the mechanical or semi-mechanical production of the pre-assembly is considerably simplified.
  • the components of the preassembly assembly can be completely electrically wired outside the housing by the mounting on the common circuit board.
  • the electrical or electronic function of the circuit breaker can thereby also be tested before inserting the circuit board in the housing, which production errors detected early, and follow-up costs due to increased production committee or subsequent repair of defective circuit breakers are avoided.
  • the pre-assembly of the switch contact, the trigger magnet and the triggering electronics on the common circuit board also allows a spatially particularly advantageous arrangement of these components, which favors a spatially particularly compact realization of the circuit breaker.
  • contact rails are also pre-mounted on the printed circuit board, which are used for connection of the switch contact, the trigger magnet and the triggering electronics to external power lines, and so far protrude from the housing in the final assembly state of the circuit breaker within the preassembly.
  • the pre-assembly in this embodiment advantageously contains the entirety of the current and / or live parts of the circuit breaker, so that the final assembly of the circuit breaker is reduced to purely mechanical manufacturing steps.
  • the housing is formed in a preferred embodiment of the circuit breaker essentially by a housing pan and a housing cover placed on this, wherein the circuit board with the parts pre-assembled thereon is received in the final assembly state approximately parallel to the housing cover in the circuit breaker housing.
  • the printed circuit board directly adjoins the housing cover. All other functional parts of the circuit breaker, in particular the moving parts of the release mechanism are thus arranged in the final assembly state on the side facing away from the housing cover side of the circuit board in the interior of the housing tub.
  • the release magnet is preferably designed as a holding magnet.
  • the trigger magnet is thus coupled to the trigger mechanism such that it the circuit breaker held in an energized state in a non-triggered position.
  • the triggering of the circuit breaker is thus done by deactivation or shutdown of the release magnet, and not by energizing.
  • the formation of the release magnet as a holding magnet allows a comparatively small dimensioning of this magnet, especially since no active magnetic energy pulse must be applied to trigger the circuit breaker. Rather, the circuit breaker triggers in the release magnet formed as a holding magnet due to an elastic restoring force of the trigger mechanism.
  • the compact design of the holding magnet designed as a trigger magnet advantageously further contributes to the structural reduction of the circuit breaker.
  • the release magnet is aligned with respect to its longitudinal axis substantially perpendicular to the direction of movement of the switching contact during opening and closing.
  • the trigger magnet is - again to achieve a particularly compact design - aligned with respect to its longitudinal axis substantially perpendicular to the longitudinal direction of the housing.
  • the longitudinal direction of the housing in this case is designated that direction in which the housing has its greatest extent. This is usually the direction that connects a housing front side to a housing rear side.
  • the housing front side in this case is that side of the housing, at which an operating element, in particular a control knob or a rocker switch protrudes out of the housing to the outside.
  • the rear side of the housing that side of the housing is called, at which the circuit breaker is electrically contacted, so in particular so the contact rails described above emerge to the outside.
  • the circuit breaker is preferably an overcurrent circuit breaker which triggers when an overcurrent exceeding a predetermined current threshold occurs.
  • the circuit breaker triggers depending on the load for different holding times.
  • the triggering electronics are set up in this case in the case of very high short-circuit currents after short hold times, and in case of lower overcurrents (overload), switch off after longer hold times.
  • the release electronics preferably takes into account the magnitude of the load current.
  • the trip electronics will take into account the squared load current as a measure of the load current's electrical power.
  • the tripping electronics are preferably again subdivided into a plurality of tripping stages with load-dependent respectively different dwell times.
  • the circuit breaker in a preferred embodiment has an undervoltage release function and / or overvoltage release function. Furthermore, it can be provided that the circuit breaker additionally or alternatively triggers in the presence of another particular thermal tripping condition.
  • multi-pole versions of the circuit breaker according to the invention are also provided. These include - in particular in a common housing - one of the number of poles corresponding plurality of switching contacts, which can be opened and closed simultaneously reversibly coupled via triggering mechanisms.
  • a separate printed circuit board is expediently provided per pole in the context of such multi-pole embodiments, on which the switching contact and in each case one of this pole associated tripping electronics are pre-assembled.
  • the contact rails necessary for the connection of the switching contact and the tripping electronics to external power lines are already firmly preassembled on each printed circuit board.

Furthermore, at right angles to the plate 11 in the region of the rear wall 7 edge facing pins 14 are formed, which are approximately accurately inserted in complementary slots 15 of the rear wall 7.
  • the circuit breaker 1 further comprises a printed circuit board 20, which is used in the assembled state substantially parallel to the housing cover 4 in the housing 2.
  • circuit board 20 On the circuit board 20, three electrical contact rails 21, 22 and 23, and a substantially serving as a trigger element of the circuit breaker 1 electromagnet 24 soldered. Furthermore, a triggering electronics 25, not shown here, is arranged on the printed circuit board 20 for controlling the electromagnet 24.
  • the contact rails 21 and 23 are used for contact closure with a load circuit 26 to be monitored (FIG. Fig. 3.6 ).

  • a longitudinal direction Y parallel to the side walls 8, 9 and a transverse direction X directed from the side wall 8 to the side wall 9 are indicated here.
  • the contact rails 21, 22 and 23 in their main surface extension are each aligned approximately parallel to the side walls 8 and 9 and thus approximately at right angles to the surface extent of the printed circuit board 20.
  • the contact rails 21 and 23 are in each case arranged in the immediate vicinity of one of the side walls 8 and 9, while the contact rail 22 is arranged approximately centrally between the other two contact rails 21,23.
  • Each of the contact rails 21,22,23 is led to connection purposes with a free end 34,35,36 each through a corresponding slot 37 in the rear wall 7 to the outside.
  • Each slot 37 is closed on the housing cover 4 side facing in the assembled state otherwise by one of the pins 14.
  • a contact surface 45 which likewise projects approximately at right angles and which corresponds to the contact surface 42, is integrally formed on the corresponding fixed end 44.
  • the assembly formed from the contact spring 41, the contact surface 42 and the contact surface 45 is hereinafter referred to as the switching contact 46.

  • the guide 69 is optional designed as a groove or slot.
  • the switching rocker 6 corresponds via the plunger 33 with the release lever 32nd
  • the shift lever 31 in turn acts on the one hand by means of a retaining lug 70 with a retaining shoulder 71 on the short leg 56 of the release lever 32 together. On the other hand, the shift lever 31 acts on the contact spring 41 via an active surface 72.

Otherwise (i B > k 0 ), the comparison module 110 0 outputs a trigger signal A, due to which the energization of the electromagnet 24 is interrupted, and the circuit breaker 1 is thus triggered.

In this case, the control program 100 generates the trigger signal A when the detected voltage amount falls below the threshold value.
