Definitions

  • the invention relates to an electrical bobbin, suitable for automatic feeding to a winding device and for automatic winding, with a winding space delimited by flanges and with an open-edge flange recess into which a locking lug arranged on the winding mandrel of the winding device engages in such a way that the bobbin is secured against rotation can be wound.
  • Previously used for automatic winding bobbins have flanges with slot-like, largely parallel contact surfaces, into which, during winding, a rigid latching nose arranged parallel to the longitudinal axis of the winding mandrel and offset to the winding mandrel is immersed, under the action of which the coil former is secured against rotation relative to the winding mandrel.
  • Flange breaks occur to a considerable extent, particularly when the winding devices are automatically equipped with bobbins of this design.
  • One of the reasons for this is the rigid alignment of the latch.
  • the nature of the receiving slots previously used for the locking lug does not ensure a positionally secure, ie geometrically exact arrangement of the connecting pins for the winding wires injected into the coil former flange. When the winding wires are automatically wound onto these connecting pins, which are not exactly aligned with one another, this likewise leads to manufacturing difficulties during winding and to failures.
  • the present invention has for its object to provide a bobbin of the type mentioned, by which flange breaks can be avoided in particular during automatic winding and which can also be locked during winding so that a secure application of the winding wires to the electrical connection pins is possible.
  • the invention provides in a bobbin according to the preamble of the claim that the flange recess has at least sections of contact surfaces for a wedge-shaped, radially and resiliently lockable nose against the bobbin.
  • the entire flange recess is preferably wedge-shaped.
  • This wedge-shaped design of the flange recess which is to provide sufficient contact surfaces for the likewise wedge-shaped latching lug at least in sections, is always a safe, ie. H. quasi elastic and thus non-destructive engagement of the resilient locking lug in the flange recess is possible, with a sufficiently rotationally secured fixing of the coil former on the winding mandrel and thus a correct application of the winding wires to the connecting pins being ensured with sufficiently large contact surfaces between the flange recess and the locking lug.
  • a coil body designated by 1 in FIG. 1 has flanges 2 with webs 5, 6 integrally formed on a flange. These webs have wire guide slots 7, 8 directed towards the winding space and carry electrical wire connecting pins 9 injected to one another in a specific geometric orientation.
  • the web-free flange 2 this known embodiment of a coil body, has an open-edge flange recess 3, into which a locking lug 10, which is offset parallel to the longitudinal axis of the winding mandrel, engages during winding, in which the coil body is pushed onto a winding mandrel.
  • This "latching" ensures the rotationally secure arrangement of the bobbin 1 on the winding mandrel, not shown, during winding.
  • Difficulties in this embodiment are the accurate "dipping" of the locking lug 10, which is guided perpendicular to the plane of the drawing, into the flange recess 3, which is adapted to the circumference of the locking lug.
  • Occasional flange breaks when the flange is not exactly aligned Recess 3 to the latch 10 are inevitable in this embodiment.
  • the possibility of widening the flange recess 3 so that the locking lug 10 is guided with play in the flange recess cannot be taken up, since an exact alignment of the wire connecting pins 9 with the corresponding winding elements of the winding device is only possible when the locking lug 10 is properly seated in the flange recess 3 is secured.
  • the flange recess 3 according to FIG. 1 is replaced by a flange recess 11 which is also open at the edge, but which is widened such that at least sections of contact surfaces are present, against which a locking lug 12 with parts of its wedge-shaped tapered end faces is provided during winding 13, 14 is present.
  • 1 is also aligned in a suitable manner to the winding mandrel, not shown, can be guided radially to the coil body 1 in the double arrow direction A and is pressed during winding under the action of a spring, not shown, against the flange recess 11. Problems such as occur with the coil former according to FIG. 1 are eliminated with this arrangement.
  • FIG. 3 shows the preferred embodiment of such a coil former and a corresponding latching lug.
  • a wedge-shaped flange recess 23 here ensures the completely break-proof latching of a latching lug 20 which can also be guided in the direction of arrow A and which has wedge-shaped end faces 21, 22.
