    • H01H19/005—Electromechanical pulse generators

Definitions

  • the present invention relates to a pulse generator according to the preamble of claim 1.
  • the present invention is concerned inter alia with the task of designing a pulse generator in such a way that false pulses, such as additional pulses due to contact bruises, are avoided, the pulse generator is simple in construction, efficient to manufacture and a compact design is possible.
  • a housing part made of insulating material or metal which is advantageously designed in the form of a box lid or a trough and has two end faces 2 and 3, two side walls 4 and 5 and a bottom 6.
  • a gear 7 is provided, which with its axis of rotation 8 in an opening 9 made in the bottom 6, e.g. a bearing bush 10 attached or molded on the outside of the base 6 is rotatably mounted.
  • a leaf spring 12 is attached vertically in the direction of the center point 11 of the gear 7, the upper end 13 of which is fastened in a fastening block 14 attached to the upper end face 2, in particular molded on.
  • the attachment takes place, for example, by pressing in or deforming the attachment block 14, for example by squeezing or hot forming.
  • the lower end 15 of the leaf spring 12 protrudes into the uppermost tooth gap 16 of the gear 7 in the rest position and thus determines a locked rest position of the gear 7.
  • two transverse slides 17 and 18 are arranged displaceably mounted perpendicular to the leaf spring 12. These can be arranged next to one another, but preferably, as in the exemplary embodiment, one above the other.
  • two guide tabs 19 are provided on the bottom 6 and / or on the side walls 4 and 5, each extending from the outside inwards perpendicular to the leaf spring 12.
  • the guide tabs 19 on each side have a distance from one another which corresponds to the thickness of the two cross slides 17, 18 plus a small gap in the form of a plus tolerance, so that the cross slides 17, 18 used are easily displaceable with as little play as possible.
  • the cross slide 17 and 18 are each provided with a recess 20 and 21, in which the leaf spring 12 engages.
  • the recesses 20, 21 of the cross slide 17, 18 are arranged offset from one another such that in the rest position of the leaf spring 12 and the gear 7 the end edges 22 and 23 of the recesses 20 and 21 respectively facing the leaf spring 12 are at a short distance 24 from the leaf spring 12 are located. As a result, no vibrations of the leaf spring 12 can be transmitted to the cross slide 17 and 18 in the idle state.
  • a contact spring band 25 and 26 is arranged almost parallel to the leaf spring 12 on both sides thereof.
  • the contact spring strips 25 and 26 are fastened with their lower end 27 or 28 in the end face 3 or, according to the exemplary embodiment, in the end wall 29 of a base part 30, for example molded in.
  • the bottom part 30 can be pushed into the housing part 1 or plugged onto it, so that a box-shaped housing is formed. This connection can be done by latching and / or gluing and / or welding, for example by means of ultrasound.
  • the upper ends 31 and 32 of the contact spring strips 25 and 26 each have a movable contact 33 and 34 on both sides.
  • Each movable contact 33, 34 is assigned two fixed contacts 35 and 36 or 37 and 38, the fixed contacts 35 and 37 with the associated movable contact 33 and 34, respectively, a normally closed contact, that is to say a closed contact pair in the rest position, and the fixed contacts 36 and 38 with the respectively associated movable contact 33 and 34, respectively, form a switching contact, that is to say a closed contact pair in the switching state .
  • the cross slides 17 and 18 each have a stop edge 39 or 40, which can be formed by a cutout in the cross slide 17 or 18.
  • the stop edges 39 and 40 can, however, also extend from the contact spring strips 25, 26 lying in another, but parallel plane reaching stop arms 41 or 42 of the cross slide 17 or 18 or be formed by cuts on correspondingly wide cross slide.
  • the length of the cutouts 20 and 21 in the cross slides 17 and 18 is dimensioned such that with maximum deflection of the one cross slide 17 or 18 due to maximum deflection of the leaf spring 12 by the gear 7, the end edge 44 or 43 of the cutout 20 or 21 of the other cross slide 18 or 17 is not touched.
  • connection contacts 45 protruding through the base part 30, each of which is connected to an inner contact part, for example the contact spring strip 25 or 26 or one of the fixed contacts 35 to 38, or forms a structural unit with these.
  • the connection contacts 45 can also be a Penetrate the side wall or an end face of the housing part 1 and protrude outwards.
  • the leaf spring 12 is deflected to the right by the tooth located on the left of it. It strikes the end edge 22 of the cross slide 17 and shifts it to the right. As a result, the stop edge 39 of the cross slide 17 comes into operative connection with the contact spring band 26 and the latter is likewise deflected to the right against its own spring force.
  • the left movable contact 34 lifts off the fixed contact 37 on which it previously rested under pretension. Finally, the right movable contact 34 is pressed against the fixed contact 38 and this pair of contacts is closed.
  • the contact spring band 26 is bent slightly to the right until the lower end 15 of the leaf spring 12 springs back over the tooth edge into the tooth space left of the actuating tooth and springs in the rest position or approximately in the rest position.
  • the cross slide 17 is released and the contact spring band 26 can spring back from its switching position into the rest position by internal stress. Any reverberations of the leaf spring 12 have no effect in the form of a switching operation because they cannot influence the cross slide 17 because of the distance of the leaf spring 12 from the inner end edge 22.
  • a corresponding process is triggered when the gear 7 rotates counterclockwise with the cross slide 18, the contact spring band 25 and the contacts 33, 35 and 36.
