Definitions

  • the invention relates to a rotary encoder according to the preamble of the claim 1 and a device or a device assembly with such a rotary encoder.
  • a generic rotary encoder is known from EP 1 278 111 A2.
  • the hood is connected via a first connector the coupling element and this with a second connector with the Axis of the evaluation unit connected.
  • the coupling element is now opposite slidably executed two connectors, the Verschieueberungen perpendicular to each other.
  • the hood of the control is in one Opening a device housing out.
  • the arrangement causes 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 multiplicity of each other gripping parts, which are manufactured separately and then assembled must, is necessary.
  • the invention has the object, starting from the cited state the technique of proposing a rotary encoder which ensures with fewer components, compensate for axial misalignment.
  • Plan surface e.g., the rotary switch or a circuit board supporting the rotary switch
  • the rotary switch can be arranged and fixed on the side of the circuit board be, which lies opposite the operating head, and with its axis through protrude a hole in this circuit board.
  • the actuating head is supported on a second axis, in which case this second axis on the Clutch is slidably supported.
  • the actuator head be supported axially displaceable on the second axis, whereby e.g. a retractable actuator head can be realized.
  • the coupling element also on his the actuator head side facing a guide, in which the Actuator or slidably engage the axis carrying the actuator head.
  • the coupling element can have a fastening section, on which the actuating button or the actuating button bearing Axis (preferably via snap hooks or undercuts) is supported.
  • a holding element may be provided which the coupling element on the axis of the rotary switch stops.
  • a Guide element, the actuating head or the actuator head bearing Axis leads, which is also possible with an axial offset of the axes of rotation, without affecting the functionality of the encoder.
  • a rotary switch 2 is arranged on a printed circuit board 1 is in addition to other electrical or electronic components. It can be a potentiometer or a rotary positioner.
  • the axis 3 of the rotary switch 2 protrudes through an opening 4 in the circuit board 1.
  • the end 5 of the axis 3 is on both sides flattened.
  • a coupling element 6 is positively attached on the end 5 of the axis 3, a coupling element 6 is positively attached. It rests with its flat 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 is used. This is 8 in this guide End 5 of the axis 3 in a direction perpendicular to the sectional surface of Figure 1 displaced (see arrow R1).
  • the coupling element 6 openings 9, in which two, on engage opposite legs of a hollow axle 10 molded legs 11.
  • the serving as guides openings 9 in the coupling element 6 are formed such that the hollow axis 10 with their legs in these along the Cutting plane is displaceable (see arrow R2), while the hollow axis 10 is a positive fit is connected to the coupling element 6.
  • an actuating head 12 is supported on the hollow axis 10.
  • This bracket is formed such that the actuating head 12 in the axial direction of the hollow Axis 10 can be postponed.
  • a mechanism 13, 14, 15 arranged with a spring 16, which works on the ballpoint pen principle and allows that 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 figures 1 and 2 shown extended position can be returned.
  • a retractable knob is provided, the actuating head 12th when not in use in a (e.g., in a bore in a housing bezel, not shown) submerged position can be brought.
  • the section through the rotary encoder in Figure 2 is perpendicular to that in Figure 1.
  • the direction of displacement R1 in which the coupling element 6 opposite 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 opposite the coupling element 6 in the (in FIG 2 not visible) guide 9 is displaceable, perpendicular to the cutting plane.
  • the two orthogonal displacements R1 and R2 thus allow in their combination of movements, an axial offset when turning the actuating head 12 to compensate.
  • FIGS. 3a and 3b show the assembly of the rotary encoder.
  • the coupling element 6 on the laterally flattened end 5 of the axis 3 of the Rotary switch 2 attaches ( Figure 3a).
  • the actuating head 12 with the hollow axle 10 so attached to the coupling element that the feet 11 of the hollow axle 10 engage in the guides 9 in the coupling element 6.
  • the coupling element 6 has a structure 17 which is integrally formed on both sides Bevel 18 is equipped with undercuts behind which within the hollow axis 10 arranged and integrally formed on this fastening elements 19th when plugging the actuator head 12 with the hollow shaft 10 on the Snap coupling element 6 in place.
  • the actuating head 12 with the hollow axis 10 fixed (but displaceable along the direction R2) with connected to the coupling element 6 and can only with increased effort (or not at all without destroying the encoder).
  • the encoder described provides a simple and built with few parts Rotary actuator with a retractable head by the application compensate the known principle of the cardan shaft axial misalignment can.
  • the encoder can be retrofitted, i. the actuating head 12 with the hollow shaft 10 can only after the installation of the circuit board. 1 in the timer housing 2 and even after the assembly of the entire timer in the stove (ie after attaching a control panel in front of the front the watch case 20) are mounted by passing through an opening in the Control panel and / or through the opening 21 in the timer housing 20 therethrough is attached to the preassembled coupling element 6.
  • the coupling element 6 Due to the structure 17 of the coupling element 6 can also after 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 are tested, by a person, the coupling element 6 on the structure 17 touches and so the Rotary switch 2 actuated.
  • Another advantage of the encoder described is that compressive forces not be passed on the axis 3 of the rotary switch 2, but over which is supported on the surface 7 of the circuit board 1 coupling element. 6 On the circuit board 1. tensile forces are on the fasteners 19 of the hollow axis 10, the undercuts of the bevels 18 on the structure 17 of the Coupling element 6 and the retaining ring 23 on the opening boundary wall 22nd transferred to the housing 20.
  • the structure 17 of the coupling element 6 carried out in this way is that its shape corresponds to the axis of standard rotary switches so far, that existing conventional test adapter for testing the rotary switch can be used.
