Definitions

  • the invention relates to a contact sleeve for insertion into a recess of a housing or support component of a measuring mechanism, which can be electrically conductively connected to the measuring mechanism, wherein a contact or fastening screw can be screwed into the recess, through which a circuit board in contact with one frontal mouth area of the recess can be pressed and a conductor track area of the circuit board can be connected to the contact sleeve in an electrically conductive manner.
  • the object of the invention is to provide a contact sleeve of the type mentioned at the outset, which ensures a high level of contact reliability and can be used unchanged for the most varied arrangements of the conductor track region on the printed circuit board.
  • the contact sleeve has at its end facing the circuit board an approximately radially outwardly extending flange-like extension which extends into the front mouth area of the recess between the housing or carrier component and the circuit board which can be pressed thereon.
  • This design makes it possible to arrange the conductor track area on the one hand on the side facing away from the housing component, the screw serving both as a contact screw and as a fastening screw.
  • the conductor track area is arranged on the side facing the housing component.
  • the flange-like extension lies over a large area on the conductor track area and thus reliably establishes contact.
  • the screw only has the function of fastening the circuit board to the housing component and pressing the conductor track area onto the flange-like extension.
  • the flange-like extension is not only used for contacting, but also forms a mounting stop when inserting the contact sleeve into the recess of the housing component.
  • the flange-like extension acts to a certain extent as a spring arm and is clamped between the housing component and the circuit board when the screw is screwed on, as a result of which both the reliability of contact is increased and manufacturing tolerances can be compensated for.
  • the contact sleeve is particularly simple to manufacture if the flange-like extension is formed by one or more radially outwardly directed tabs.
  • the contact sleeve can consist of a sheet metal part bent into a sleeve, in the end region of which there are flap-forming axial incisions which enable the flaps to be bent radially outwards. This training also improves the spring behavior and thus the contact security of the extension.
  • the contact screw can preferably be pressed with its screw head, which widens radially with respect to the screw shaft, onto the conductor track region arranged on the side of the printed circuit board facing away from the housing or carrier component.
  • a contact hole disk can be arranged between the screw head and the conductor track area, the contact reliability being increased even further if a spring washer can be arranged between the screw head and the contact hole disk.
  • the two variants of the circuit board contacts can be used at each end of the recess. This means that a single version of a contact sleeve can be used for a wide variety of mounting variants of the printed circuit board, so that the contact sleeve can be manufactured and stored inexpensively.
  • the flange-like extension extends radially outwards at an acute angle to the front mouth area of the housing or carrier component, then the Spring effect of the flange-like extension and thus the contact reliability is increased.
  • the recess and the contact sleeve can have a circular or even a polygonal, in particular square, cross section.
  • the polygonal cross-section has the advantage that it provides positive locking against rotation about the longitudinal axis of the contact sleeve in the recess.
  • the contact sleeve has a continuous longitudinal slot, spreading and thus securing the position of the contact sleeve in the recess can be achieved in a simple manner by screwing in the contact or fastening screw.
  • the longitudinal slot preferably extends along a corner of the contact sleeve.
  • the contact or fastening screw can be screwed into the contact sleeve in a self-tapping or thread-tapping manner.
  • the inner wall of the contact sleeve and / or the surface of the contact flange facing the conductor track has a highly conductive, easily plastically deformable layer, such as, for. B. a tin layer is provided.
  • This layer is preferably made of a material which additionally has a low contact resistance and is not oxidizing.
  • the shape of the adjoining one is adapted both in the area of the screw shank and in the area of the flange-like extension Parts and thus a high level of contact reliability achieved.
  • a further embodiment for the screwability of the screw consists in that at least one radially inwardly directed projection for engaging in the thread of the contact or fastening screw is formed on the inner wall of the contact sleeve.
  • a plurality of projections are preferably formed in accordance with the pitch and pitch of the thread of the contact or fastening screw.
  • the contact sleeve can be inserted into the recess with force and / or friction and / or positive locking.
  • the contact sleeve can be provided on its outer lateral surface with a roughening which, for. B. is formed by knurling.
  • the contact sleeve has a projection protruding from its outer surface.
  • the contact sleeve can also have a resilient arm projecting from its outer lateral surface.
  • the contact surface can have an opening on its outer lateral surface, into which an appropriate extension projecting from the inner wall of the recess can be engaged.
  • the contact sleeve can have a contact tab for connecting the measuring mechanism. Is the contact tab by bending a partially punched out wall section from the Formed outer surface of the contact sleeve, no additional material is required for the contact tab.
  • the measuring instrument shown in FIGS. 1, 2 and 3 is a measuring mechanism with a winding carrier 1 carrying windings 4 with laterally arranged support arms 2 for fastening a printed circuit board and optionally also for fastening the measuring instrument to a carrier.
  • a permanent magnet is rotatably mounted within the windings 4, depending on the current supply to the windings, from which a pointer axis 5 projects outside the windings.
  • a pointer axis 5 projects outside the windings.
  • the contact sleeves 7 and 7 ' have laterally projecting contact tabs 8, with which the winding ends 9 are connected.
  • the contact sleeves 7 and 7 ' are provided with flange-like outwardly directed tabs 10, which extend approximately radially along the end region of the recesses 6 and 6'.
  • a printed circuit board 11, 11 ′ or 11 ′′ is placed on the end face of the support arms 2 and fastened by a fastening screw 12.
  • This fastening screw 12 extends through a recess 13 in the printed circuit board 11, 11 'or 11''and is screwed with its shaft 14 into the contact sleeve 7'.
  • the fastening screw 12 is a self-tapping screw which cuts with its thread into the inner wall of the contact sleeve 7 '.
  • the fastening screw 12 presses the printed circuit board 11, 11 ′ or 11 ′′ via the tabs 10 of the contact sleeve 7 ′, which extend between the support arm 2 and the printed circuit board 11, 11 ′ or 11 ′′, onto the end faces surrounding the recess 6 Mouth area of the support arm 2.
  • the printed circuit board 11 ' is a flexible printed circuit board, between which and the tab 10 a support plate 16 is also arranged.
  • the copper-clad conductor area 17 of the printed circuit boards 11 and 11 ' is arranged on the side facing the screw head 15.
  • the screw head 15 lies on a contact plate 18 resting on the conductor track region 17 and a spring washer 19 on the conductor track region 17.
  • the conductor track region 17 is conductively connected to the contact sleeve 7 'via these disks 18 and 19 and the fastening screw 12, which is made of elastically conductive material and also serves as a contact screw.
  • the conductor track region 17 is arranged on the side of the printed circuit board 11 ′′ facing away from the screw head 15 and lies directly on the tab 10 of the contact sleeve 7 ′.
  • the contact sleeve 7 ' shown in FIGS. 4 and 5, which is provided for the measuring instrument according to FIG. 3 and the exemplary embodiments of FIGS. 8 to 10, has a square cross section and a longitudinal slot 20 along one corner.
