Definitions

  • the present invention relates to a pulse generator according to the preamble of claim 1.
  • Such a pulse generator is known from DE-A-31 20 598.
  • the outer side of the switching rocker interacting with the leaf-shaped pressure spring is designed in the form of a circular arc.
  • a V-shaped so-called hairpin spring is provided on the side of the rocker arm opposite this outside.
  • Each leg of the same is supported on a housing projection and the part of the hairpin spring which is coiled at the connection point of the two legs in the manner of a helical spring is attached to a pin formed on the rocker arm.
  • the shift arm in the Rest position fixed.
  • the movable contacts are fixed on one side of the rocker arm and press resiliently against a switch plate provided with fixed contacts.
  • a pulse generator which has a lever which can be deflected by a toothed disc and can only be pivoted about an axis and which can actuate a contact spring of two sets of contact springs with lateral arms.
  • the rest position of the lever is maintained by two opposing spiral springs.
  • an angle lever pretensioned by a tension spring is provided, which presses against the toothing of the toothed disk with a rotatable roller and causes the toothed disk to latch.
  • the contact springs of the contact sets are from the lever and the Toothed washer facing away.
  • a pulse generator is known from EP-A-0127 043, in which a helical spring clamped on one or both sides is provided between the two mutually parallel contact spring sets, which can be deflected laterally by the toothed disk and thereby bring a movable contact spring into the closed position.
  • the coil spring is deflected perpendicularly to the lateral deflection direction when the tooth tip is skipped.
  • the spiral spring serves both as a return spring and as a detent spring for locking the toothed lock washer in the rest position.
  • the object of the present invention is to achieve a pulse generator of the type mentioned at the outset, while maintaining the compact design with little expenditure on components and therefore inexpensive and easy to assemble.
  • This design of the pulse generator means that a single, inexpensive leaf or bar spring acts both as a detent spring and as a return spring.
  • a housing of a pulse generator which consists of a base part 2 and a cover part 3, in particular a tub or box-shaped part.
  • Support supports 4 for the base part 2 can be provided in the base part 2.
  • Fixed contacts 5, 6, 7, 8, 9, 10 are preferably provided in the bottom part 2 and protrude externally as connection elements. For example, these are inserted or molded into the base part 2, a contact spring 11, 12 being fastened to the upper fixed contacts 5, 6 in a mechanically strong and electrically conductive manner. In particular, it is attached by welding.
  • the fixed contacts 7, 8 and 9, 10 provided on the free end 13 of the contact springs 11 or 12 form pairs of contacts with the contacts 14 of the contact springs 11 and 12, in particular changeover contacts.
  • the contact springs 11, 12 are biased so that their inner contacts 14 each rest against the inner fixed contact 8 or 9 in a contact-safe manner, thus forming a normally closed contact.
  • a toothed disc 16 rotatable about an axis of rotation 15 and a plate-shaped switching rocker 18, which can be pivoted about a pivot axis 17, are arranged such that the connecting line 19 between the axis of rotation 15 and the pivot axis 17 runs at least approximately parallel to the contact springs 11, 12.
  • the shift arm 18 has a bearing bore 20 or a slot 20 running in the Ruhr position of the shift arm 18 in the direction of the connecting line 19 for mounting on the pivot axis 17.
  • the switching rocker 18 engages in the rest position with a tooth-like projection designed as a latching element 21 in an opposite tooth gap 22 of the toothed disk 16.
  • the rest position is obtained by a compression spring 23, which presses the shift rocker 18 against the toothed disk 16 in the case of an elongated hole. It is designed, for example, as a rod or leaf spring and presses on the outer side 24 of the switching rocker 18 opposite the latching element 21.
  • the outer side 24 is preferably designed in a straight line or inward in an arc shape, so that two lateral outer edges 25, 26 are formed, which on the Apply compression spring 23.
  • the position of the switching oscillation 18 is fixed and, after deflection by the toothed disk 16 as a result of the force of the compression spring 23, after the rotary shaft 27 has been released, it can be pivoted back into the rest position. At the same time, the toothed disk 16 and the rotary shaft 27 are also locked in the last rotary position.
  • the return can be supported in that limit stops are provided which prevent the rocker arm 18 from pivoting further and instead cause the rocker arm 18 to shift in the respective direction of the elongated hole 20, indicated by the dashed arrow 30, when the toothed disk 16 is turned further.
  • the latching element disengages from the moving tooth in that the tooth slides over the inclined contact surfaces 31 of the latching element 21. The latter can thus snap into the next tooth gap 29.
  • the shift rocker 18 is moved upwards.
  • the inner fixed contacts 8, 9 serve as a limit stop, which is achieved by corresponding positioning thereof in connection with the shape of the side walls 32 of the switching rocker 18.
  • the contact springs 11, 12 can run above but also below the toothed disk 16, the rocker arm 18 being effective in two planes by the latching element 21 in the plane of the toothed disk 16 and the arms 28 are arranged in the plane of the contact springs 11, 12.
  • a transmission gear is provided in this embodiment. This comprises a toothed pinion 33 which is rigidly coupled to the toothed disk 16 or forms a structural unit with it, and a toothed wheel 34 which meshes with the latter. The latter can be driven via the rotary shaft 27.
