  • an electrical connector is formed in each case from an inner conductor, a dielectric and a separate outer conductor.
  • the inner conductor and the outer conductor of each coaxial connector must be soldered separately on a conductor track.
  • the applicant himself describes an angle connector of the QMA connector series under the type designation 85 QMA-50-0-3 / 1 1 1 N (see SUHNER, Coaxial Connector General Catalog, Edition 2003/2004, p. 188).
  • the housing of this connector is made of metal and has molded directly onto the housing solder feet for insertion and soldering in holes of a printed circuit board.
  • the connector interface is a QMA type receptacle and is positioned so that the connector axis is at 90 ° to the solder feet, or parallel to a printed circuit board.
  • the connector series QMA is a snap connector with lock.
  • the applicant also discloses a connector of the QMA series under the type designation 22 QMA-50-0-1 / 1 33 (see SUHNER, Coaxial Connector General Catalog, Edition 2003/2004, p.185), in which the connector can be pressed directly into an opening in a chassis with its outer housing.
  • the outer conductor thus makes contact with the ground of a housing, while the inner conductor protrudes into the housing and is exposed for contacting.
  • Rosenberger has announced a 59S2AG-400A5-Y connector (see data sheet by Rosenberger, RF_35 / 1 2.04 / 3.0) for the automotive industry according to the FAKRA standard, in which two connectors with their outer conductors are fastened to a tinned steel stamped and bent part with soldering feet , The connector pair can now be fixed by means of the stamped and bent part directly on a printed circuit board or inserted into corresponding holes. The inner conductor and the stamped bent part, which contacts the outer conductor, are soldered.
  • a multiple connector to be shown, in which With little effort, the number of connections can be adapted to the respective field of application and varied.
  • An embodiment of a connector according to the invention consists essentially of an electrically conductive mounting body and one or more interface parts.
  • the mounting body preferably consists of a stamped and bent part with molded contact feet, preferably in the form of press-fit pins.
  • the interface part has a coaxial construction, which can be connected at its first end to a coaxial Cegenstecker. At its second end, the interface part is crimped into an opening in the mounting body (e.g., press-fitting and / or crimping) so that the outer conductor of the coaxial interface part electrically contacts the mounting body.
  • another type of connection may also be used, for example screwing, soldering or gluing.
  • the advantage of pressing is the comparatively simple manufacture. If necessary, the contact surface may be surface treated to increase the contact ability. Good results can be achieved with galvanic or other coatings.
  • the inner conductor of the interface part protrudes through an opening in the mounting body and also has at its lower end a contact foot which is arranged in the vertical direction substantially at the same level as the contact feet of the mounting body or slightly above it , This ensures that not all contact feet come into active connection at the same time.
  • the contact foot of the inner conductor may also be formed as a press-fit.
  • the contact feet of the mounting body, as well as the one or more inner conductor may be configured so that they can be placed on corresponding pads of the circuit boards or inserted directly into holes in the circuit board and soldered.
  • the contact feet as lateral cheeks are formed with molded Einpressiten whose integral design is particularly efficient at a mounting body as a stamped and bent part and has a high stability. It is also possible to press in beads that have a positive effect on the mechanical stability even of thin sheets. Particularly in automated processing, increased mechanical stability is advantageous, e.g. when the press-fit pins are pressed into the openings provided for this purpose.
  • the preferably used Einpressstatten are metal pins with a range for pressing in a non-metallized (non-conductive) or metallized (conductive) bore of a printed circuit board (in the art also called via), which usually without subsequent soldering reliable electrical contact with allow the metallization of the borehole and thus the corresponding trace or serve only for anchoring the connector.
  • a printed circuit board in the art also called via
  • comparatively rigid or elastic press-fit pins are preferred. When trained as a rigid pin whose press-in area is massive and usually designed as a square. The forces necessary for the connection result from a deformation of the printed circuit board hole into which the massive press-fit pin is pressed.
  • An elastic pin has a press-in area with an elastic deformation zone and the forces necessary for the connection are applied primarily by the deformation of the elastic press-fit pin.
  • a variant of an elastic press-in pin with deformation zone is centrally crushed in the press-in and / or has an opening and is flared lens-shaped.
  • the press-fit pin can have a shoulder above the deformation zone or the press-in area which is larger than the drill hole and serves as a stop.
  • the contact feet are arranged on both sides of the base area, with the interface parts mounted thereon.
  • the mounting body is substantially U-shaped, so that the interface parts have a distance from a printed circuit board.
  • the contact feet can be designed so that they are designed as cheeks and have recesses. These recesses allow on the one hand a visual inspection of the components, which are arranged in the space below the connector and on the other hand, an air circulation to prevent heat build-up under the connector. They also serve to reduce the required material consumption. Variants are conceivable where the axial direction of the interface parts are parallel or at right angles to the printed circuit board. For special applications other angles are possible.
  • a suitable arrangement of the contact feet for example a staggered arrangement of the front and rear feet, optimum material utilization in the production of the mounting body, for example as a stamped and bent part, can be achieved by reducing the material loss during punching.
  • the design of the mounting body as a stamped and bent part ensures great flexibility in the design of the connector. It is also possible with a comparatively simple tool to punch the mounting body of several coherent segments step by step. As a result, a simple adaptation to the desired number of connections is possible and the punching tool can be configured independently of the number of interface parts. So also individual connectors can be produced.
  • the mounting body is designed so that at least three mutually staggered contact feet are present per segment or interface part, for example, two contact feet are arranged on the side in the vicinity of which the opening for the interface part is provided.
  • the interface part with its inner conductor contact foot can also be arranged approximately centrally between the three contact feet of the mounting body.
  • the arrangement close to the two front contact feet has the advantage that forces are transmitted from the interface part on the contact feet ideally on the circuit board. Another advantage is that this still room on the base for additional elements, such as a fastener in the form of a threaded hole, which can be manufactured in the same operation, is present.
  • the design with three contact feet of the mounting body also offers the advantage of a stable state of a single segment or a single connector.
  • a band-shaped, endless starting material enables optimized material utilization, since less material is lost as a rule.
  • perforations or predetermined breaking points can be provided, which allows a subsequent splitting of a multiple connector.
  • To increase the stability can additionally serve a bead over any number of segments.
  • stamping bending technology also allows easy adjustment for different orientations of the base or the Interfaceachse.
  • a sheet of bronze, brass, nickel silver or steel can be used in a thickness of 0.2 to 2.0 mm.
  • the connector has a sheet-metal stamped bent part with integrally formed contact feet with press-in pins for pressing into openings of a printed circuit board and one or more interface parts, which are each arranged in an opening of the stamped and bent part and operatively connected thereto.
  • the interface part may be crimped with an edge of the opening.
  • the stamped and bent part has a substantially U-shaped cross-section.
  • the injection pins are flared lenticular and may have an opening and / or a web.
  • the press-fit pins are rigid.
