  • known electronic control circuits for vehicle door locking systems often comprise a transmitter or a transceiver with a resonance circuit which, for example, consists of the series connection of an induction coil with a capacitance.
  • the induction coil generates an electromagnetic field that is received by the external data carrier.
  • the desired range is typically around one and a half meters. To achieve this range at the desired frequency, an induction coil with a large inductance must be provided become. Such an inductance can only be achieved if the induction coil comprises the largest possible ferrite core.
  • the induction coil must be installed outside the car body so that the electromagnetic field is not damped.
  • the optimal position for mounting the induction coil is inside the car door handle, very close to the data carrier of an approaching person and to the other electronic and mechanical parts of the car door locking system.
  • the induction coil or even the entire electronic circuit is sometimes cast into a polymeric mass, primarily to protect it from moisture.
  • the electronics of the control circuit are sensitive to water and dust and must therefore be protected against moisture infiltration.

However, the assembly of the handle with such seals is a process which has to be carried out manually and is therefore expensive. If an identical control circuit is determined for installation in different handles, the problem of water resistance must be solved anew for each handle. It has also been proposed to encapsulate the electronic components in a thermoplastic insulating material. Experiments were carried out with a "hot melt" material (for example Macromelt), which is sprayed at a temperature of approximately 215 ° degrees and at low pressure.

  • Ceramic or polypropylene capacitor with a value of approx. 1 5 to 18nF. It is used to match the impedance of the induction coil to the driver stage of the microcontroller. It is preferably positioned and / or fastened in the cover by further ribs 40.

These cables go through the housing 1, 13; a rubber seal is preferably provided to make the housing watertight.
  • Dispensing with potting in the housing 1, 13 permits longitudinal play of the various components, in particular the induction coil, when the housing bends, so that the electrical contacts and the ferrite core do not have to absorb any pressure.
  • FIG. 3 shows a second embodiment variant of the control circuit, in which the connecting cables 12 are connected to the printed circuit board 2 via a plug 122-123.
