Definitions

  • the invention relates to an outside door handle of the type referred to in the preamble of claim 1 (as known, for example, from US-A-5 340 174).
  • the functions triggered by the capacitive sensor contained in the outside door handle may include, for example, an access authorization to the vehicle and serve for more comfortable opening and closing.
  • the corresponding outside door handles have one or more functional surfaces via which the capacitive sensor can be addressed.
  • a disadvantage of such an arrangement is that it may cause interference of the capacitive sensors and so an unwanted operation or locking of the door mechanism is done. These disturbances lead to malfunctions and thus to energy loss.
  • the disturbances often come about through environmental influences, such as rain or increased humidity.
  • the outside door handle also has a second or even additional functional areas are additionally accompanied by the problem that the capacitive sensors of the different functional areas influence one another and thus further malfunctions occur.
  • the object of the invention is therefore to avoid the aforementioned disadvantages and to provide a cost-effective outside door handle with at least one capacitive sensor, which works trouble-free despite environmental impact.
  • This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.
  • Such a screw connection which additionally generates a clamping pressure, is simple and inexpensive to produce. It represents an effective and quick way of contacting the panel with the ground potential of the vehicle.
  • the outside door handle 10 shown in Fig. 1 consists of an electrically conductive aperture 11 and a handle portion 12. These two parts are connected by a connecting means 14 with each other.
  • the aperture 11 is often made of chrome or chromium-plated material, which is easy and inexpensive to manufacture and has a nice visual effect.
  • a capacitive sensor 20 which serves to trigger functions on the vehicle. These functions may be, for example, that the vehicle automatically opens and closes after the access authorization of the person operating the outside door handle has been established. Other examples include the start-up of open windows or the activation of the alarm system of the vehicle.
  • the electrically conductive diaphragm 11 is connected to the ground potential of the vehicle.
  • the connection 21 to the ground potential is located in the interior 13 of the outside door handle 10.
  • This connection of the electrically conductive panel 11 to the terminal 21 of the ground potential is realized via an electrical conductor 30 and a screw 15, which also at the same time the connecting means 14 of the diaphragm 11 with the handle ridge 12 represents.
  • An electrical conductor 30 is connected at its one end 31 via the screw 15 with the diaphragm 11, while the other end 32 of the conductor 30 is connected to the interior located in the handle 13 terminal 21 of the ground potential of the vehicle.
  • This conductor 30 connects so easily and inexpensively, the aperture 11 with the ground potential of the vehicle.
  • the electrical conductor 30 is designed as a metallic tongue 34.
  • This has a hole 35 through which the screw 15 is guided.
  • the hole 35 at the end 31 of the metallic tongue 34 is designed as a plate spring 36.
  • the plate spring 36 is generated by crimping the inner edge 37 around the hole 35 around. If now a clamping pressure 16 is generated by tightening the screw 15, this is particularly secured by the special design of the metallic tongue 34.
  • the plate spring 36 prevents namely the loosening of the screw 15 and amplifies the clamping pressure 16.
  • the plate spring 36 additionally secures the connection between the Aperture 11 and the handle ridge 12, so that even with a flowing deformation of these two parts a connection is ensured.
  • the electrical conductor 30 is a metallic wire 33 which is clamped by the screw 15.
  • the metallic wire 33 may at its one end 31 and a ring or ring sector-like training, through which the screw 15 is guided. As a result, a better clamping of the metallic wire 33 comes about.
  • the conductor 30 In order to avoid corrosion on the diaphragm 11 and / or the electrical conductor 30, it is advisable to produce the conductor 30 from a stainless sheet or wire whose potential of the electrochemical series is close to the potential of the material from which the diaphragm 11 consists. In fact, in the case of corrosion of the conductor 30, it would not be possible to ensure the continuity of the electrical connection between the diaphragm 11 and the terminal 21 of the ground potential of the vehicle. In addition, corrosion on the diaphragm 11 would still lead to an ugly appearance, which affects the attractiveness of the vehicle.
  • the conductor 30 is connected to a in the handle interior 13 located film 22, which in turn is connected to the ground potential of the vehicle.
  • a film 22 is space-saving and easy to assemble.
  • the conductor 30 is soldered at its other end 32 to the terminal 21 of the ground potential, or with the film 22. This type of connection ensures a conductive connection that is easy to implement and does not require additional fasteners such as screws, rivets or the like.
  • a prior at least partial coating of the conductor 30 with tin is advantageous.
  • the handle interior 13 of the exterior door handle 10 is at least partially filled by its intended use with a filler to protect the electronics 20 from moisture and environmental influences.
  • the embodiments shown here merely represent, for example, realizations of the invention. This is not limited thereto, but rather various modifications and designs are possible. So it is conceivable, for example, to provide the handle remainder directly with a shape that represents the connection to the ground potential of the vehicle or the connection to the ground potential in such a way that the aperture can be connected directly via the screw, without the use of an electrical conductor , Furthermore, other embodiments of the electrical conductor are conceivable.
  • the one end of the conductor may have various shapes, for example, form a half or partial ring and / or be provided with leaf springs.
