Definitions

  • the invention relates to a contact tongue for an electrical switching device, according to the preamble of claim 1 or 3, an electrical switching device with a contact tongue according to the preamble of claim 4 or 6 and a method for producing an electrical contact tongue according to the preamble of claim 20 or 21.
  • the invention may, for. B. in so-called mechanical attenuators, d. H. switchable damping lines are used.
  • the application is not limited to this.
  • a contact tongue of the present type is a tongue-shaped component of electrically conductive material whose free contact end is movable transversely to the broad side of the tongue body to open or close the electrical contact with a mating contact body.
  • the contact tongue In order to avoid a joint in the region of the base end of the contact tongue, the contact tongue consists of an elastically flexible material, so that the transverse movement of the contact end can be achieved by bending and bending back the contact tongue.
  • the depressions can be produced by embossing, erosion or etching, wherein the contact surface is coated with a contact layer of electrically conductive material.
  • a contact tongue for a small electrical switch is described, wherein the contact tongue for contacting contact elements arranged on both sides has on both sides in each case one or more coatings of conventional coating and etching techniques.

  • the object of the present invention is It is therefore in particular to design the contact surfaces in such a way that particles leave the contact regions of the contact tongue after as short a time as possible and thus ensure optimum contact between contact spring and mating contact body at all times and for a long time.
  • the recess extends into the tongue body.
  • an enlarged receiving space for From the abrasion or pollution originating particles present whereby a caused by the particles susceptibility is significantly reduced.
  • the invention is particularly advantageous in the case of a contact layer formed by a thin film, because the thickness of such a contact layer is very small and therefore the depth of a depression incorporated only in the contact layer is insufficient to eliminate the risk of interference emanating from the particles.
  • the embodiments of the invention are therefore particularly well suited for a switching device according to the preamble of claim 2, because at the contact of the at least one transversely offset mating contact body, the contact end of the contact tongue performs a sliding movement on the mating contact body and is therefore expected to considerable wear and abrasion, the particles
  • the electrical contact does not affect and endanger, because the particles are harmless in the at least one depression.
  • the switching devices according to the invention according to claim 2 is therefore less susceptible to disturbances of the electrical contact.
  • the contact tongue can have a contact layer of electrically conductive material in its end region on both broad sides and have at least one depression on both broad sides.
  • a contact tongue is suitable to be contacted by bending to one side and to the other side in each case with a mating contact part, and it is therefore preferably suitable for the aforementioned attenuator lines.

  • the embodiment of the invention is suitable both for a contact tongue, which consists entirely of electrically conductive material or one which is coated at least in the region of the contact surface with a material layer of an electrically conductive material, preferably with gold or a gold alloy.
  • Both the tongue body and the contact layer can be made relatively thin.
  • the contact layer is preferably a vapor-deposited material layer.
  • the contact tongue is made of a thin material, it is advantageous not to produce the outer shape of the contact tongue by punching or cutting, but by etching.
  • the production according to claim 7 then takes place when both the outer contour of the contact tongue and the at least one recess are produced simultaneously by etching.
  • Such a process is not only fast and inexpensive, but also gentle on the edges, leaving the reed in its flat shape without being bent, or even tending to give rise to bending.
  • a particularly inexpensive production is that a plurality of contact tongues are etched with their depressions simultaneously from a film.
  • the designated in their entirety by 1 switching device has a contact tongue 2, one end of which is a base end 3 and the other end is a contact end 4.
  • the contact tongue 2 is held in the region of its base end 3 by a holder 5 with respect to a simplified base 6 shown fixed.

  • the respective displacement or displacement path is greater than half the distance between the two Jacoborialeilen 7a, 7b, so that in the contact position, the respective contact surface 9 with a compressive force on the associated mating contact part 7a, 7b abuts, wherein the contact tongue 2 is slightly bulged and a slightly occupy S-shaped form as it Fig. 1 shows.

  • the electrical contact between the contact tongue 2 and the associated mating contact part 7a, 7b depends inter alia on the cleanliness of the abutting contact surfaces. If there are one or more particles between the contact surfaces, the electrical contact is impaired.
  • Such particles may be general pollution.
  • Another reason for the accumulation of particles between the contact surfaces is that at a switch by the contact at the contact surfaces wear takes place, inevitably resulting in abrasion with fine particles.
  • the contact tongue is bent not only in the above-described S-shape, but there is also a directed in the longitudinal direction of the contact tongue 2 relative movement between the contact surfaces, resulting in greater wear.
  • a similar cause for the formation of harmful particles also consists in the fact that, when the contact tongue is bent back and forth, a relative displacement also takes place between the contact tongue 2 and the adjusting pins 12a, 12b and the adjusting pins 12a, 12b and the guide pieces 15a, 15b which leads to comparable wear with resulting particles.
