Definitions

  • Circuit breaker for example circuit breaker
  • the invention relates to a protective switching device, for example a circuit breaker, the switch lock of which can be unlatched between a manual control element and at least one movable contact arm at a latching point between a pawl and a release lever by a release device.
  • switch locks with so-called flying latching that is to say a portable latching point
  • flying latching that is to say a portable latching point
  • a portable latching is achieved with components arranged flat next to one another.
  • the invention has for its object to develop a protective switching device with a compact switch lock and contact arrangement, which enables a portable latching point.
  • Movable contact arm m of a strap that encompasses this is mounted on both sides of a first axle bearing with the strap so that it can be moved and rotated.
  • the pawl is also mounted off-center on this axle bearing.
  • the tab has another axle bearing on both sides, on which the release lever is mounted so that it can move in a stationary manner off-center.
  • the tab and the movable contact arm also pivot about this axis when it is not in contact with a fixed contact.
  • the first axle bearing limits the switch-off path of the contact arm, for example when the axle is in contact with a housing stop. It is therefore also referred to as the Ausschlag.
  • the tab forms a stable support element for the latch and release lever, which can be arranged in a plane above or below the contact area.
  • the stable tab structure enables a quick, low-friction contact opening with a motion-free guided contact arm. No elongated hole guidance is required for this.
  • the asymmetrical structure over several levels has the further significant advantage that it avoids the ignition that occurs when a moving contact strikes and bounces back against a stop that limits the contact path after being switched off, again approaching the fixed contact of the contact pair. Since the stop in one plane is arranged eccentrically to the contact arrangement, that is to say outside the plane of the contact arrangement, torsion vibrations result in the event of a strike from the impact anchor of a trigger device, which have a damping effect on the switching process.
  • the structure described thus combines on the one hand a stable, torsion-free guide for the movable contact arm with, on the other hand, damping torsional vibrations when switched off on the release lever. This prevents sudden ignition. A useless guidance of the contact arm also prevents restless contact positions.
  • the structure over several levels also has the advantage that a compact arrangement of the switch lock and contact arm is achieved.
  • the axle bearing for the release lever can advantageously be arranged with respect to the axle bearing for the contact arm on the contacting side of the contact arm.
  • a spring on the contact arm is sufficient to generate the contact force and the tear force at the contact opening. This in turn does not require several spring forces, which in turn would compensate for and decrease in different switching processes.
  • the pawl can store a coupling rod to the manual control element at a mobile Kimken bearing spaced from the bearing for the contact arm, which requires the construction of the key switch.
  • the contact arm can advantageously be formed in two parts from components arranged one above the other in the axis.
  • a base part can be made of mechanically strong material and a contact carrier or a contact-forming head area can be made of electrically highly conductive material that can be optimized for the protective switching device.
  • Base part and contact carrier can be arranged overlapping one another in the axial direction, which enables simple manufacture.
  • the spring-loaded switching mechanism can be connected to the manual control element, so that when the hand is switched on, a body with a distance between the pair of contacts and a waste edge is pulled away, so that a sudden switch-on takes place.
  • Such jump switches are known m different designs (DE-A-4 016 364).
  • Such snap-action switches lead to particularly intense switching impacts, which are dampened by the construction according to the invention.
  • a magnetic trigger can be arranged so that its plunger, also known as an impact anchor, engages the trigger lever to form a long lever arm.
  • a spring acts on the contact arm between the axle bearing for the contact arm and the axle bearing for the release lever.
  • the spring is advantageously arranged on the side facing the manual control element and is designed as a tension spring. The contact force and the contact opening force are then achieved by this spring without having to overcome a counter-spring force.
  • the tab can be connected to a switch position indicator. The movable contact arm can be guided in the tab between additional guide ribs.
  • FIG. A tab encompasses a movable contact arm on both sides and forms axes for an axle bearing.
  • FIG. 2 shows the assembly according to FIG. 1 in the manner of an exploded view.
  • FIG. 3 shows a protective switching device with a manual control unit, switch lock and contact arrangement and a plunger in the switched-off position for the sake of clarity because of the magnetic trigger not shown.
  • FIG. 4 the switch-on position is shown in the figure of FIG. 3.
  • FIG. 5 schematically illustrates a jump switch, with further components according to FIGS. 3 and 4 being omitted for the sake of clarity.
  • FIG. 6 the impact initiation for unlatching is illustrated in the representation according to FIGS. 3 and 4 and in connection with a reproduced switching spring, the plunger of a magnetic release just hitting the release lever.
  • FIG. 7 An additional switch position indicator is shown in FIG. 7 in the representation according to FIGS. 3 and 4.
  • the protective switching device has a movable contact arm 1 according to FIG. 1, which is mounted in a tab 2 encompassing it on both sides of a first axle bearing 3 in the kinematics of the switch lock with the tab, so that it can be moved and rotated.
  • the tab 2 has a further axle bearing 4 on both sides, on which a release lever can be mounted so that it can rotate in a non-central position.
  • the tab and the movable contact arm also pivot about this further axis if it is not in contact with a fixed contact 7, as shown in FIG. 3.
  • the first axle bearing 3 also limits the switch-off path of the contact arm 1. Compare FIG. 3. 3.
  • the switch-off position is shown in FIG.
  • the fixed axle bearing 4 for the release lever is arranged with respect to the movable axle bearing 3 for the contact arm 1 on the contacting side of the contact arm.
  • the contact arm 1 forms a contact pair with a fixed contact 7.
  • the pawl 6 supports in a portable pawl bearing 8 spaced from the bearing 3 for the contact arm 1, a coupling rod 9 to a manual control element 10.
  • the contact arm 1 is formed in two parts from components arranged one above the other in the axial direction.
  • a base part 11 made of mechanically strong material is mechanically firmly connected laterally to a contact carrier 12 or a head region forming a contact part, for example by means of electro spot welding.
  • the electrodynamic triggering can be carried out by an electromechanical trigger, the plunger 13 of which is illustrated.
  • FIG. 3 The switch-on position after pivoting the manual control element 10 out of the switch-off position according to FIG. 3 is illustrated in FIG. A conventional electrothermal release is not shown in FIG. 4 or in FIG. 3 for the sake of clarity.
  • FIG. 6 in addition to the illustration according to FIG. 4, a spring 14 acting on the contact arm 1 is shown between the axle bearing 3 for the contact arm and the axle bearing 4 for the release lever 5.
  • the moment is reproduced when the plunger 13 strikes the release lever 5 as a result of an electrodynamic release in order to initiate the release by the pawl 6 falling off the release lever 5. It is advantageous if the plunger 13 engages the release lever 5 to form a long lever arm 15.
  • FIG. 5 shows an additional snap-action switching mechanism 16 which is connected to the manual control element 10.
  • a distance-giving body 17 When switched on by hand, a distance-giving body 17 is pulled away with a waste edge 18 between the contact pair 19, so that there is an abrupt switch-on in which the contact arm occurs on the fixed contact 7.
