Definitions

  • the present invention relates to a connection means according to the preamble of claim 1 and a hearing aid according to the preamble of claim 7.
  • Hearing aids such as hearing aids
  • a housing that consists of at least two housing shells.
  • the housing shells must be connected to the finished, closed housing to complete the hearing aid.
  • screws are often used for the connection of such housing shells. If the housing shells are made of plastic, so-called self-tapping screws can be used. These screws need in contrast to threaded screws no mating thread, in which they are screwed, but only a hole, which have a smaller diameter than the threaded surfaces of the screw. At the top of the threaded surface of such screws is formed as a cutting surface, which cuts into the bore and thus created the mating thread itself.
  • threaded screws can be used, which engage in nuts, which are arranged in correspondingly shaped receptacles on the inside of the housing shells.
  • housings are known in which the housing shells are connected by means of smooth pins.
  • Such housings are, however, in contrast to bolted housings divided parallel to the pin axis, which leads compared to transverse to the longitudinal axis of the screws separate housing shells to more expensive and therefore more expensive injection molding tools.
  • This eyelets must be created for the connection, which significantly increases the complexity of the injection molding tools used for this purpose.
  • the head parts of the pins are visible from the outside and the corresponding holes, even if they are smaller than in the solution with screws, also tend to accumulate dirt.
  • the connecting means for hearing aids with a housing that at least two to be connected to each other
  • Housing shells consists, according to the invention consists of a one-piece, extending straight along its longitudinal axis pin which has at least one outwardly tapered retaining surface towards both ends.
  • This pen can now be used as
  • Openings of the housing shells are introduced. By squeezing the housing shells penetrate the two ends of the pin in the two holes, respectively. Openings.
  • the retaining surfaces nestle frictionally against the inner wall of the respective bore respectively. Opening and thus form a frictional connection, which fixes the housing shells in a completely closed state together.
  • the connection itself, ie, the connecting pin is arranged by the two arranged on the inner surface of the housing shells, preferably designed as a blind hole bores. Openings not visible from outside. This eliminates the risk of contamination from drilling holes to the outside, respectively. Openings.
  • the pin has a central part with a cylindrical lateral surface.
  • a backlash-free and exact fit of the housing shells can be achieved during assembly.
  • At least two, preferably three, spaced apart along the longitudinal axis retaining surfaces are formed towards both ends.
  • the retaining surface is surrounded by a conical or helical around the entire circumference
  • the end of the retaining surface directed towards the middle part has a sharp edge, preferably a substantially right-angled edge
  • the connecting means made of plastic, which allows a cost-effective production by injection molding.
  • a plurality of recesses arranged opposite one another in each case in an axis are arranged transversely to the separating edge of the housing shells on the housing inner wall, to which a connecting means is assigned.
  • Another advantage is the fact that the space required for the recesses is not greater than, for example, the space required by known snap connections, however, a much lower strength, respectively. Have stability.
  • the recesses are circular or polygonal recesses, from the opening to the bottom of the recess at least two different diameters, respectively. Have cross-sectional areas, wherein the first diameter resp. Cross-sectional area at the opening is greater than the following second diameter resp. Cross sectional area.
  • Such recesses can be easily manufactured and facilitate the insertion of the connecting means, respectively. the tips of the lanyards.
  • the first diameter corresponds approximately to the diameter of the cylindrical middle part of the connecting means and the second diameter is smaller than the outermost diameter of the retaining surfaces of the connecting means.
  • a particularly good fit accuracy when assembling the housing shells is achieved, which are positioned without play on the cylindrical middle parts.
  • a particularly good clamping effect on the retaining surfaces of Connecting means achieved, which allows a particularly stable connection.
  • the assembly resp. the assembly of the housing shells is very simple, it only need the connecting means are inserted into the recesses of a housing shell and then brought the second housing shell on the connecting means and thereafter merely to be compressed.
  • hearing aids all in connection with the collection and
  • Treatment of sound and playback are meant to the ear, such as headphones, hearing protectors, hearing aids and in particular behind-the-ear hearing aids.
  • Figure 1 shows the view of an open hearing aid consisting of two housing shells and arranged therebetween, according to the invention connecting means.
  • 2 shows the cross section through the hearing aid of Figure 1 in the assembled state in the region of a connecting means.
  • connection means according to the invention.
  • FIG 1 the upper housing shell 1 and the lower housing shell 2 of a hearing aid of the type BTE (behind the ear - behind the ear) is shown in the open state.
  • the housing shells 1, 2 have conventional openings 3 on the outside, recesses 4 and webs 5 on the inside for receiving the electrical and mechanical components (not shown for clarity) of the hearing aid.
  • FIG. 2 shows the cross section through the composite housing of the hearing aid according to FIG. 1 in the region of a connecting means .6.
  • FIG. 3 shows in more detail the view of a connecting means 6 according to the invention.
  • the cylindrical center part 8 can be seen particularly well, whose outer diameter is preferably slightly larger than the largest diameter of the conically formed retaining surfaces 9.
  • three circumferential conical surfaces 9 on each are advantageous Side of the middle part 8 is arranged.
  • the outermost conical surface 9 ' is advantageously formed slightly longer than the other conical surfaces, and has a slightly lower inclination relative to the longitudinal axis L.

Abstract

L'invention concerne un moyen d'assemblage pour appareils auditifs présentant un boîtier comportant au moins deux coques (1, 2) qui doivent être assemblées entre elles, ledit moyen étant caractérisé en ce qu'il comprend une tige (6) en une seule pièce, s'étendant le long de son axe longitudinal (L), présentant avantageusement une partie médiane (8) à surface latérale cylindrique et, vers chacune de ses deux extrémités, au moins une surface de retenue (9, 9') amincie coniquement vers l'extérieur. Cette tige (6) peut dès lors être introduite, en tant que tige de liaison, dans deux trous, ou ouvertures (7) des coques (1, 2) du boîtier, directement opposés l'un à l'autre. Par pression exercée sur les coques (1, 2), les deux extrémités de la tige (6) pénètrent dans les deux trous ou ouvertures (7).
