Definitions
- the present invention relates to an electrically conductive Anwickelpfosten according to the preamble of claim 1. Furthermore, the invention relates to an inductive sensor comprising at least one such Anwickelpfosten.
- Inductive sensors are already known which comprise a bobbin, a circuit board and two Anwickelpfosten.
- the bobbin of the inductive sensor is usually constructed so that it can accommodate windings of a coil in a winding space.

- Bobbin a shell core - also called ferrite core - be housed to manipulate a magnetic field generated by the coil.
- the board is used for electronic control and evaluation of the coil.
- the board can be arranged upright on the bobbin.
- the beginning and end of a coil wire of the coil may be wound around an Anwickelpfosten and anterminiert thereon, so that the coil wire is fixed in particular for the winding process.
- Anwickelpfosten have the shape of a straight pin.
- the beginning and end of the coil wire, after each fixed to a Anwickelpfosten still need to be connected to the board, for example by connecting both for the beginning and for the end of the coil wire in each case another wire the board with the Anterolster antermin faced coil wire.
- the object of the present invention is therefore to provide an improved and simplified connection of a wound on the Anwickelpfosten coil wire with a circuit board of an inductive sensor.

- an electrically conductive Anwickelpfosten for a coil of an inductive sensor is provided, wherein the electrically conductive
- Anwickelpfosten is angled to produce an electrically conductive connection to a circuit board. Since the Anwickelpfosten is made of an electrically conductive material and is angled to make an electrically conductive connection to a circuit board, it is possible to connect both a beginning and an end of a coil wire directly via a Anwickelpfosten with a circuit board of the inductive sensor, without another electrical
- An advantage here is the one-piece design of the electrically conductive Anwickelpfostens that acts simultaneously as an electrical connection element to the board.
- This design is not only inexpensive and easy to manufacture, but also acts to support the board, so that the entire structure of the inductive sensor is more stable and durable compared to known inductive sensors.
- the Anwickelpfosten can either be angled in by having a kink or bow at an end facing the board or otherwise deviates from a straight pin shape, or alternatively be arranged to be attached as a straight pin in an angled manner obliquely to a bobbin to make an electrically conductive connection to the board.
- the electrically conductive Anwickelpfosten is double angled, so that it is approximately J-shaped.
- This embodiment is particularly suitable for a construction of an inductive sensor in which both one or more Anwickelpfosten and the board upright on the bobbin stand and extend approximately parallel to each other. If the electrically conductive Anwickelpfosten double angled and J-shaped, a first leg of the angled portion of the Anwickelpfostens extend approximately at right angles from a central axis of the Anwickelpfostens towards the board. A second leg of the angled portion of the
- Anwickelpfostens may in turn extend from the first leg of the angled portion of Anwickelpfost from approximately at right angles, so that the second leg extends in a plane of the board or directly in front of the board and parallel to the board, so that the second leg in a known manner can be connected to the board, for example by soldering.
- the electrically conductive Anwickelpfosten be angled so that it is Z-, L-, C-, U-, V- or I-shaped.
- the decisive factor here is that the electrically conductive Anwickelpfosten is angled in such a way that it extends in operation, so when it is installed in an inductive sensor, so towards a circuit board that he electrically conductive at a designated location with the board can be connected
- Rim and / or ridges are provided on an outer surface of the electrically conductive Anwickelpfostens to hold a beginning or an end of the coil wire of the coil of the inductive sensor.
- grooves are recesses which project into a plane of the outer surface. Elevations, on the other hand, are discharges that protrude from the plane of the outer surface. The expert knows how to groove,
- the grooves and / or elevations may guide the coil wire and prevent the coil wire from slipping.
- the grooves and / or elevations are preferably adapted to the coil wire, for example by each groove and / or elevation respectively by the diameter of the
- the electrically conductive Anwickelpfosten in cross section on a first bending side and a parallel to the first bending side second bending side.
- the electrically conductive Anwickelpfosten also has a first side connecting the parallel bending sides and a second side connecting the parallel bending sides. Further preferably, the two sides connecting the parallel bending sides face each other.
- the grooves and / or elevations are provided only on the connecting sides of the parallel bending sides of the outer surface of the electrically conductive Anwickelpfostens.
- the angled part of the Anwickelpfostens can be particularly easily produced by bending. Because when bending a profile around one with a substantially flat bending side, the material experiences the highest compressive stress at the inner bending radius, while the opposite material experiences the highest tensile stress at the outer bending radius on the other bending side.

- the first end can be poured into the bobbin, plugged, clamped, screwed or other known manner with the
- the coil wire is preferably wound on and anterminated at the first end of the Anwickelpfostens, but may also be wound and anterminiert at the second end of the Anwickelpfostens or over the entire length of the Anwickelpfostens.
- a central axis of the electrically conductive Anwickelpfostens is arranged substantially parallel to a plane of the board and perpendicular to a winding plane of the coil.
- the at least one electrically conductive Anwickelpfosten may extend from its first end substantially parallel to the board.
- the Anwickelpfosten can then at its second end - preferably substantially at right angles - angled towards the board and with the board be connected.

- the electrically conductive Anwickelpfosten is angled such that the electrically conductive Anwickelpfosten Z-, L-, C-, U-, V- or I-shaped.
- the shape of the Anwickelpfostens should be chosen so that the
- Anwickelpfosten is connected at its first end to the bobbin and executed at its second end to the board and connected to the circuit board.
