Definitions

  • all known installation built-in switches can also be switched off manually, by actuating a pivotable or tiltable hand lever or a push button. Manual switching from the off to the on position saves energy. When it is switched off manually or triggered automatically, the stored energy is released and the switch jumps to the off position.
  • Switch locks of known design are designed in such a way that when switching manually from the on to the out position, the contact or the contacts are / are opened continuously in linear motion.
  • the contact pressure of two contacts is initially reduced and then gradually separated from each other.
  • An arc arises between two contact plates which move away, which is not only undesirable but also leads to increased material wear and further impairments, in particular of the contacts and the housing made of plastic.
  • a key switch of a known type which can be operated manually by means of a switching lever, essentially has the following assemblies: - A tab group with a three-armed design Knee lever, wherein a first arm is articulated on a pivotable switching cam actuated by the gear lever, a second arm on a pawl tab that can be pivoted and locked, and a third arm on a plunger for actuating the electrical contact system.
  • the arms which are distributed in a star shape, are held together by a central rivet.
  • a slide hand that can be moved by the switch cam with means for transmitting power to the ratchet hand for manual switching off.
  • the release pawl is actuated by the moment or release slide of an electromagnetic release and possibly an undervoltage release or by the compensator of a thermal bimetallic release.
  • the inventor has set himself the task of creating a method and a switch lock for switching installation built-in switches which, regardless of the speed of actuation of the switch lever, produce a rapid shutdown and ensure the freewheeling function when triggered automatically.
  • the object is achieved in relation to the method in that the switch-off force generated manually on a shift lever is transferred to a gradation of a slider hand that can be displaced in the direction of a latch hand until a latch tab disengages from the pivoting latch hand and is opened by stored spring force , or an automatically actuated release pawl is pivoted until its nose lies next to a ratchet nose and a pawl tensioned with spring force corresponds to one of the nose heights Appropriate pivoting movement is allowed, which is transferred to the jack hand, whereby the jack tab disengages from the pivoting jack hand and is opened by stored spring force, which causes a sudden opening of the electrical contacts of the installation switch.
  • a sudden arc is prevented by the sudden opening of the electrical contacts, which leads to the immediate interruption of the current flowing through the built-in switch. Significantly less erosion damage occurs on the contact plates, the surrounding plastic housing parts are not damaged.
  • the latch tab opens due to overcurrent or undervoltage when the switching cam or lever is blocked.
  • the type of tripping (manually or electrically in the event of overcurrent or undervoltage) is preferably displayed externally.
  • the object is achieved according to the invention in that a bearing pin of the first arm of the tab group is extended in the switching cam, the slide hand has a sliding surface with a gradation on which the bearing pin moves the slide hand in the direction when it is switched off manually the pawl group is in a sliding position, and the release pawl and pawl have lockable lugs which, when disengaged, allow the pawl to pivot with the pawl hand.
  • the gradation in the sliding surface of the slide hand is preferably approximately rectangular.
  • the pivot pin which swivels with the switch cam, can thus transmit the force to the gradation without essential lateral components and move the pawl hand to disengage the pawl tab.
  • the height of the gradation in the sliding surface of the slide hand preferably corresponds approximately to the diameter of the bearing pin.
  • the slide hand is preferably pulled back into the original position by a tension spring.
  • An articulated connection with the pawl hand means that this too is returned to the original position.
  • This articulated connection is expediently established by appropriately arranged bolts.
  • a shift axis 14 which is essentially square in cross section, receives a shift lever (not shown).
  • a cam of the shift lever engages in a guide groove 16 when it is attached.
  • a torsion spring for resetting the shift lever is arranged outside the metal plate when the shift lock is working, wrapping around the shift axis 14.
  • Rigidly connected to the switching axis 14 or integrally formed with it is a switching cam 18 which serves to transmit power to other components of the switching lock.
  • the tab group essentially comprises a pawl tab 20, a 5-part tab with three arms pivotally held together by a rivet 22 and a plunger 24.
  • the 5-part tab transmits the pivoting movement or the latch tab 20 into a linear movement transmitted to the tappet 24.
  • the first, one-piece arm 30 of the 5-piece tab is articulated to the switching cam 18 via a bearing pin 32 which is elongated in the direction of the viewer.
  • the second arm 34 of the bracket is connected via a rivet 36 in the corner region thereof to the latch bracket 20, likewise in an articulated manner.
  • the third arm 38 which is formed in two parts like the second arm, is ver via an axis 40 with the axially movable plunger 24 bound.
  • the disengagement is initiated by a movement of the slide hand 52, which is directly in engagement with the pawl hand 44 (manual release) or by the pawl 42, which transmits its pivoting movement to the pawl hand 44 via the rivet 50 (automatic or electrical release).
  • Fig. 1 the switched-on position of the switch lock 10, the latch tab 20 is latched via its latch 74 on the latch 72 of the latch hand 44. Likewise, the nose 68 of the release pawl 60 engages on the nose 70 of the pawl 42. The second arm 34 and the third arm 38 of the 5-part tab form a practically elongated angle, the plunger 24 is therefore pressed far down. The contacts of the installation built-in switch are closed.
  • the phase shown in FIG. 3 shows the key switch immediately after opening the latch tab 20, FIG. 4 a little later.
  • shift lever (not shown), which is attached to the shift axis 14, is blocked, it can still be switched off; this freewheeling function is guaranteed by the system.
