Definitions

  • the invention relates to a circuit breaker for motor vehicles according to the preamble of claim 1.
  • the object of the present invention is to provide a circuit breaker for motor vehicles which automatically breaks the circuit in the event of an accident and with which motor vehicles can also be retrofitted.
  • the task solution according to the invention creates a circuit breaker for motor vehicles which automatically interrupts the circuit in the event of an accident in the motor vehicle and thus prevents cable fires and electrical short circuits and consequent motor vehicle fires.
  • Motor vehicles can easily be retrofitted with the circuit breaker according to the invention.
  • the circuit breaker is simply connected between the battery and ground.
  • the drawing shows a circuit breaker 2 with a pendulum-like around a metal bearing bush 6 arranged switch arm 8 made of metal with weight 10.
  • the bearing bush 6 is clamped between two spaced circular segment-shaped plates with the aid of a screw bolt 4.
  • One plate forms an upper part 12 made of an insulating material, for example bakelite resin, and the other plate forms a lower part 14 made of metal, for example brass.
  • the lower part of the screw bolt 4 holds a bracket 16 to which a fastening tab 18 is screwed by means of a screw connection 20. With the aid of the fastening tab 18, the circuit breaker 2 can be mounted on an engine compartment wall.
  • the screw bolt 4 holds a bracket 22 between the mounting bracket 16 and the lower part 14, in which a push-button switch 24 is fastened, the spring-mounted push pin 26 of which is guided in a bore 28 of the lower part 14 and into a rear recess 30 of the switch arm 8 in the circuit-closed position of the Circuit breaker 2 engages.
  • bushings 36, 38 are clamped between the upper and lower part by means of countersunk screws 32, 34, each of which holds a leaf spring 40, 42 with an angle 44, 46.
  • the upper part 12 has a rectangular hole 48 in which a metal contact body 50, which rests under pressure on the switch arm, is guided, which has a threaded shaft 52 which projects through a bore 54 of a guide plate 56 which acts on the pressure body and on which a nut 58 for screwing the contact body onto the guide plate.
  • the guide plate 56 is held on both sides of the contact body 50 by means of countersunk screws 58, 60 which are screwed into the upper part from the inside and pass through bores in the guide plate, the guide plate 56 being slidably mounted on the bushings 62, 64 surrounding the countersunk screws.
  • Knurled nuts 66, 68 are screwed onto the outwardly projecting threaded shafts of the countersunk screws 58, 60.
  • Helical compression springs 70, 72 are supported between the knurled nuts and the guide plate 56.
  • the switch arm 8 has a longitudinal recess 74 on the outside, into which one of the leaf springs 40 or 42 with the bends 44, 46 engage when the switch arm is pivoted.
  • a bore 76 can also be provided in the switch arm 8 for attaching a pull cable 78 which can be actuated from inside the vehicle, as a result of which the circuit breaker 2 can be actuated manually.
  • the circuit breaker is connected between the negative pole of the battery and ground.
  • the pendulum-like switch arm 8 In the event of an acceleration force occurring due to a collision, regardless of the direction, the pendulum-like switch arm 8 is pivoted from its central circuit closing position 84 to the left or right into one of the two circuit interruption positions 86, 88, in which the circuit is interrupted, since in these two positions the contact body 50 is no longer in contact with the switch arm 8.
  • the pivoting into the power cut position can also be done by operating the pull cable 78.
  • the reset is then carried out manually, the correct operating position, i.e. H. the closed circuit can be indicated by a light-emitting diode (not shown) arranged on the circuit breaker 2.
  • the circuit breaker 2 is preferably attached to the engine compartment wall in an inclined position of 45 ° in the engine compartment. A vertical arrangement or any angular arrangement is also possible.
