Definitions

  • the invention relates to an electrical connection device for producing a solder joint according to the preamble of claim 1 and to a method for the production thereof according to claim 17.
  • Solder joints are among the most common types of connection in the field of electrical and electronic equipment technology.
  • an electrical connection between connecting wires or generally connecting lines on the one hand and electrically conductive contact elements on the other side are to be made, which consist for example of non-solderable materials.
  • strip conductors as may be provided on a plate-shaped substrate, or generally plate-shaped conductors in the form of metal sheets or metal strips, etc. belong.
  • Non-solderable strip conductors are often used in the form of thin-walled sheets, which can be mounted, for example, on dielectric substrate.
  • the strip conductors or strip lines can also be mounted in front of a metallic surface using air as a dielectric.
  • Strip waveguides which are mounted at a distance in front of an electrically conductive reflector plate and are held by means of an insulating body which is mounted on the reflector plate, are frequently used, in particular in mobile radio technology.
  • an electrical connection connection must optionally be made using copper wires, etc. It would be advantageous if such good solderable connection wires can be soldered to the strip conductors.
  • galvanic contacts are known in which, for example, two printed circuit boards or printed conductors are screwed together.
  • a method and a device for fastening an insert in a plate material is for example from CH 383 082 known. It is assumed that a metal, a sheet or an insulating material, which is designed plate-shaped.
  • a cylindrical insert is to be pressed, which is provided in a partial height in the axial direction on its outer periphery with a knurling.
  • a pressing tool ie a punch and serving as a counter support cylindrical hollow punch can then be pre-pressed in the direction of plate, the cylindrical insert, wherein a cylindrical material portion of the plate is punched out by the hollow punch.
  • the cylindrical insert can be pressed.
  • the outer circumference of the press-fit piece corresponds in principle to the inner diameter of the cylindrical punched-out bore, wherein only the knurling of the insert piece may have a slightly larger outer diameter in order to be able to scrape the axially extending flanks of the knurling into the surface of the cylindrical recess in the plate during assembly. This is to ensure a good interference fit.
  • a comparable solution is also from the DE 10 2007 057 501 A1 known.
  • a press-in connection using a bolt with an outer contour is preferably proposed in the form of knurling, which is adapted to a correspondingly matched by its diameter surface design of a hole in a busbar.
  • the anchoring of a two-stage plug element with stepped arranged Jardinrändelung and a correspondingly stepped recess of a wall portion of a housing wall is made of DE 102 59 803 B3 to be known as known. Again, by the interaction of the knurling on the outer circumference of the plug-in element and the inner surface of the stepped bore to be ensured by notching effected optimum interference fit.
  • the WO-2005 079 127 discloses an electrical connection device as in the preamble of appended claim 1.
  • connection device by the features specified in claim 1 and with respect to a corresponding manufacturing method for such a connection device according to the features indicated in claim 17.
  • Advantageous embodiments of the invention are specified in the subclaims.
  • press-fit bolts have a stamp-shaped connection side on which a solder connection can be made.
  • the press-in bolts are pressed in the manner of a punch through a plate-shaped non-solderable material, whereby the non-solderable material is pierced in particular as strip conductor material, which receives a broken circumferential edge material in the penetration of the press-fit pin. With this edge of the material, a base peripheral area of the press-in pin is held while achieving high press-in and clamping forces, the head of the press-in pin protruding beyond this strip conductor material edge being available as a soldering point.
  • the clamping portion on the peripheral edge of the press-in pin which cooperates with the broken-up during the pressing-in edge of the material Vietnamese solderable plate material and holds the press-in bolts may preferably be provided with a circumferential knurling. This creates an excellent frictional connection between the wall material of the press-in pin and the non-solderable material adjacent thereto.
  • the press-fit bolt is ultimately used as a press or stamping die to deform a corresponding plate-shaped material, wherein the press-in pin is then left behind in this quasi after penetration of the non-solderable material.
  • the advantage also lies in the fact that the corresponding deformation of the non-solderable material is carried out by the press-in pin itself, so that ultimately there are no tolerance deviations in the press connection between the outer and inner part.
  • the flanged edge of the material which is formed during the pressing of the press-in and protrudes beyond the thickness of the plate-shaped material, at the same time also serves to prevent tilting of the press-in pin. Because of the flanged edge of the material of the bolt is held with a larger total area of the surrounding material edge in a press fit. In the case of thin sheets, otherwise the penetration in the plate material would be critical since the pin could otherwise tilt more easily if pressure or tensile forces are applied laterally. The solution according to the invention therefore also significantly improves the long-term stability under radial tensile or compressive loads.
  • the electrical connection connection thus formed is particularly suitable for the connection of coaxial cables, with particularly good solder joints are then also feasible when the press-in pin, for example, tinned or silvered or, for. made of brass, etc.
  • the press-in pin is provided in the circumferential direction with at least one circumferential recess or groove, which may be formed concave in axial vertical section, for example (different cross-sectional configurations of this groove are possible). It is also possible that, for example, two such, circumferential in the circumferential direction on the outer circumference of the Einpressbolzens grooves are provided which are offset from one another in an axial height. These at least one or more grooves should come to lie in the compressed state in the range of the material thickness of the plate-shaped or sheet-like material. As a result of this embodiment, in the remaining contact region, an even increased pressure and contact pressure between the plate-shaped or sheet-like material on the one hand and the circumferential surface of the injection bolt is ensured, which avoids possible intermodulation even better and safer.
  • the invention can be used in all relevant areas in which electrically solderable and electrically non-solderable materials are to be soldered together. This is especially true in a solder joint in electrically highly conductive materials such as coaxial inner conductors with strip conductors.
