Definitions

  • the present invention relates to a plug-in connection for connecting assembly circuit boards to a backplane wiring board, in which the knives are arranged on the assembly board side and the contact springs on the backplane wiring side.
  • Such a plug connection, in which the knives are arranged on the assembly circuit board side, is known, for example, from DE 88 14 942 UI.
  • the object of the present invention is to provide a plug connection of the type mentioned at the outset, which is distinguished by a simple structure and is easy to produce.
  • the knives can be fastened to the assembly circuit board by means of SMD technology become.
  • This consistent application of SMD technology results in great potential for cost savings. So z. B. when using SMD technology on the assembly side, complete operations and manufacturing facilities for press-fit technology, wave soldering, etc. are eliminated.
  • a connector is known, the knives of which are encapsulated in plastic in a male connector body and are applied to a circuit board by means of SMD technology.
  • the male connector body has the construction described above as disadvantageous.
  • FIG. 1 shows a cross section through a plug connection according to the invention
  • FIG. 2 shows a section above the rear wall wiring board corresponding to FIG. 1,
  • FIG. 3 cross sections through certain parts of the plug connection according to the invention
  • FIG. 4 shows a section above the rear wall wiring board corresponding to FIG. 3,
  • Figure 6 is a schematic plan view of an assembly circuit board with a male connector according to the present invention.
  • Figure 7 is a schematic front view of a male connector of the connector according to the invention.
  • the knife bar is assigned to the assembly circuit board 1.
  • the knives 4 are held in a molded plastic body 3 in a male connector body 3, the male connector body 3 being arranged perpendicular to the component circuit board 1.
  • the extensions of the individual knives are soldered on the assembly side using SMT technology.
  • the fact that the knives are arranged on the assembly side eliminates the problem with the grease coating of the springs when using SMT technology.
  • the male connector body 3 can be divided into modules, each module being assigned a certain number of grid points of a grid in which the knives 4 are arranged. This modular division is z. B. shown in Figures 6 and 7.
  • the contact springs consist of rotating parts bent from spring sheet metal with two contact legs and two retaining lugs 7 and are inserted into bores 6 in the rear wall wiring plate 2. This means that the contact springs 5 can be greased be inserted directly into the holes 6 of the rear wall wiring board 2. This eliminates the plastic part of the female connector body and thus saves a further assembly process.
  • the contact legs and the retaining lugs 7 of the contact springs 5 are each offset by 90 °.
  • a contact spring 5 is shown at the top in FIG. 3, in which the engagement of the rear wall wiring board 2 by the retaining lugs 7 after the introduction of the contact spring 5 into the bore 6 of the rear wall wiring board 2 is shown.
  • the holding lugs 7 prevent the contact springs 5 from being pulled out of the bores 6 of the rear wall wiring board 2 when the assembly circuit board 1 is pulled. 3, the contact spring 5 is shown rotated by 90 °, so that the contact legs can be seen.
  • a molded pre-pin 8 is provided, which fits precisely into a bore 6 of the rear wall wiring plate 2 which is not equipped with a contact spring 5.
  • the bores in the rear wall wiring board 2 are designed as blind holes 9 (FIG. 5) and the bottom of the blind hole 9 is also metallized.

Abstract

Les lames (4) sont placées côté carte de circuits modulaire (1) et les lames de contact (5) côté fond de panier (2). Les lames (4) entourées de matière plastique sont maintenues dans une réglette de contacts (3) en forme de plaque, perpendiculaire à la carte de circuits modulaire (1). Les prolongements des lames (4) dirigés vers la carte de circuits modulaire (1) sont raccordés à cette dernière selon la technique du montage en surface. Les lames de contact (5) sont constituées d'un élément rotatif cintré à partir d'une tôle à ressort, comportant deux bras de contact introduits dans des trous (6) du fond de panier (2). La technique du montage en surface peut être appliquée pour le système de connexion enfichable selon l'invention.
