Definitions

  • the invention relates to a rotary encoder according to the preamble of patent claim 1 and a device or a device assembly with such a rotary encoder.
  • a generic encoder is from the EP 1 278 111 A2 known.
  • an operating element which has a hood, a coupling element and an evaluation unit.
  • the hood is connected via a first connecting piece with the coupling element and this with a second connecting piece with the axis of the evaluation unit.
  • the coupling element is now designed to be displaceable relative to the two connecting pieces, wherein the displacement directions are perpendicular to one another.
  • the hood of the control element is guided in an opening of a device housing.
  • the arrangement has the effect that a lateral offset of the axis of the evaluation unit with respect to the center of the housing opening is compensated.
  • it has the disadvantage that a plurality of interlocking parts, which must be manufactured separately and then assembled together, is necessary.
  • the invention has the object, starting from the cited prior art to propose a rotary encoder, which ensures with fewer components to compensate for axial misalignment.
  • the coupling element preferably has, on its side facing the rotary switch, a planar contact surface with which it is supported on a likewise plane surface (for example the rotary switch or a circuit board carrying the rotary switch).
  • a planar contact surface with which it is supported on a likewise plane surface (for example the rotary switch or a circuit board carrying the rotary switch).
  • the rotary switch can be arranged and fixed on the side of the printed circuit board, which lies opposite the actuating head, and project with its axis through a hole in this printed circuit board.
  • the actuating head is mounted on a second axis, in which case this second axis is slidably supported on the coupling element.
  • the actuating head on the second axis can also be held axially displaceable, whereby e.g. a retractable actuator head can be realized.
  • the coupling element on its side facing the actuating head on a guide, in which engage the actuating head or the actuating head bearing axis slidably.
  • the coupling element may have a fastening portion, on which the actuating button or the axis carrying the actuating button (preferably via snap hooks or undercuts) is held.
  • a holding element may be provided which holds the coupling element on the axis of the rotary switch.
  • a guide element guides the actuating head or the axis carrying the actuating head, which is also possible with an axial offset of the axes of rotation, without the functionality of the rotary encoder being impaired.
  • a rotary switch 2 is arranged in addition to other electrical or electronic components. This can be a potentiometer or a rotary position transmitter.
  • the axis 3 of the rotary switch 2 protrudes through an opening 4 in the printed circuit board 1.
  • the end 5 of the axis 3 is flattened on both sides.
  • a coupling element 6 is fitted positively. It is supported with its planar contact surface 24 against the surface 7 of the circuit board 1 and has an opening in the middle, which serves as a guide 8 for the laterally flattened end 5 of the axis 3.
  • this guide 8 the end 5 of the axis 3 in a direction perpendicular to the sectional surface of FIG. 1 displaceable (see arrow R1).
  • the coupling element 6 openings 9, in which engage two, formed on opposite sides of a hollow axis 10 legs 11.
  • the serving as guides openings 9 in the coupling element 6 are formed such that the hollow axis 10 with its legs in these along the cutting plane is displaceable (see arrow R2), while the hollow axis 10 is positively connected to the coupling element 6.
  • an actuating head 12 is supported on the hollow axis 10.
  • This holder is designed such that the actuating head 12 can be pushed onto the hollow axis 10 in the axial direction.
  • a mechanism 13, 14, 15 is arranged with a spring 16, which operates on the ballpoint pen principle and allows the actuating head 12 by pressure in the axial direction on the hollow axis 10th can be pushed and held in a deferred position, unlocked by renewed pressure in the axial direction and in the in the characters 1 and 2 shown extended position can be returned.
  • a retractable knob is provided, the actuating head 12 when not in use in a (eg in a hole in a housing cover not shown) recessed position can be brought.
  • the section through the encoder in FIG. 2 is perpendicular to the in FIG. 1 ,
  • the displacement direction R1 in which the coupling element 6 relative to the axis 3 of the rotary switch 2 in the guide 8 is displaceable, in the cutting plane.
  • the displacement direction R2 in which the actuating head 12 with the hollow axis 10 relative to the coupling element 6 in the (in FIG. 2 not visible) guide 9 is displaceable, perpendicular to the cutting plane.
  • the two directions of rotation R1 and R2 arranged at right angles to one another thus make it possible, in their combination of the movements, to compensate for an axial offset when the actuating head 12 is rotated.
  • FIGS. 3a and 3b the assembly of the encoder is shown.
  • the coupling element 6 is attached to the laterally flattened end 5 of the axis 3 of the rotary switch 2 ( FIG. 3a ).
  • the actuating head 12 is fitted with the hollow shaft 10 on the coupling element, that the feet 11 of the hollow shaft 10 engage in the guides 9 in the coupling element 6.
  • the coupling element 6 has a structure 17, which is provided on both sides with integrally formed bevels 18 with undercuts behind which are arranged within the hollow shaft 10 and integrally formed thereon fasteners 19 when plugging the actuating head 12 with the hollow shaft 10 on the coupling element 6.
  • the actuating head 12 with the hollow shaft 10 is fixed (but displaceable along the direction R2) connected to the coupling element 6 and can be withdrawn only under increased force (or not at all a destruction of the encoder) again.
  • the rotary encoder described is a simple and constructed with few parts rotary actuator with a retractable head, which can compensate for axial misalignment by applying the known principle of the cardan shaft.
  • the encoder can be retrofitted, i. the actuator head 12 with the hollow shaft 10 can also be mounted only after the assembly of the circuit board 1 in the time switch housing 2 and even after the installation of the entire timer in the stove (ie after attaching a control panel in front of the timer housing 20) by is plugged through an opening in the control panel and / or through the opening 21 in the timer housing 20 through the preassembled coupling element 6.
  • the structure 17 of the coupling element 6 can also after the installation of the rotary switch 2 on the circuit board 1, the coupling element 6 on the axis 3 of the rotary switch 2 and the circuit board 1 with rotary switch 2 and coupling element 6 in the housing 20, the function of the rotary switch 2 tested be touched by a person, the coupling element 6 on the structure 17 and so the rotary switch 2 is actuated.
  • the structure 17 of the coupling element 6 is designed such that its shape corresponds to the axis of standard rotary switches insofar, Existing conventional test adapters can be used to test the rotary switch.
