Definitions

  • the present invention relates to a coaxial microwave connector.
  • a connector is intended in particular to connect two printed circuit boards or a printed circuit board to another component such as a module or a filter.
  • microwave connector is meant here and in the context of the present invention, a connector capable of ensuring the transmission of signals in the microwave range, for example at frequencies between 1 GHz and 20 GHz.
  • contact is meant here and in the context of the present invention, an element of electrically conductive material for passing the electric current.
  • an "insulating element” is an element of electrical insulating material.
  • the coaxial connectors are known, comprising a first cylindrical connector element intended to be fixed at one end to a first circuit board printed, and a second cylindrical connector member for contacting, at one end, a second printed circuit board, each connector member having a central contact and an outer contact separated by an insulator, the central and outer contacts first and second connector members having mutually contacting cylindrical bearing surfaces, resilient means being interposed between the first and second connector members and biasing the central and outer contacts of the second connector member towards the second printed circuit board.
  • the first connector element may be mechanically fastened, in particular by soldering, to the first printed circuit board and the second card is brought in abutment against the second connector element which is displaced relative to the first connector element, the contacts of the second element connector being pressed under the action of the elastic means against the conductive zones provided on the second card.
  • these elastic means are necessary to obtain a sufficient mechanical contact force, ensuring a good electrical contact.

  • a major disadvantage is that one of the mass contacts in the form of a solid cylinder is not really compressible, which does not guarantee a good electrical ground contact and absorb card-to-card tolerances relatively important.
  • the central spring induces excessive inductance, unsuitable for the transmission of microwave signals.
  • the patent US 7416418 discloses a microwave coaxial connector, said card-to-board, wherein a first spring is interposed axially between the conductive rods of the connecting elements. A second spring is interposed axially between the conductive bodies of the connection elements. The first connection element is attached to the first printed circuit board. When the second printed circuit board is brought against the second connection element, the springs push the rod and the body of the second connection element against the second printed circuit board, opposite the first connection element, so as to ensuring a satisfactory electrical contact between the second connection element and the second printed circuit board.
  • the structure of this connector remains relatively complex, especially given the use of springs.

    - ein isolierendes Element (5), das einen Schlitz (50) umfasst, der durchgehend und entlang der Achse X gestreckt ist, wobei das isolierende Element zwischen dem gestreckten leitenden Element und dem röhrenförmigen Körper eingerichtet ist, dass das gestreckte leitende Element (3) in dem Inneren des isolierenden Elements (5) derart ist, dass seine Schleife geschlossen und elastisch durch Kompression auf sich selbst zwischen einer nicht verformten Position, in der sein Scheitel (32) über das erste Ende (21) vorragt, und einer verformten Endposition, in der sein Scheitel (32) auf dem ersten Ende (21) ausgerichtet ist, verformt werden kann, wobei das freie Ende (31) des gestreckten leitenden Elements außerhalb der Schleife geeignet ist zu gleiten, indem es aus dem Schlitz (50) derart vorragt, dass es auf dem zweiten Ende (22) ungeachtet der verformten Position der Schleife ausgerichtet ist, und dass der Ring (4) außerhalb des röhrenförmigen Körpers (2) derart gehalten wird, dass er elastisch durch Aufliegen gegen die erweiterte Oberfläche (23) zwischen einer nicht verformten Position, in der er nicht in Auflage gegen die erweiterte Oberfläche ist und sein Scheitel (40) über das erste Ende (21) vorragt, und einer verformten Endposition, in der sein Scheitel (40) auf dem ersten Ende (21) ausgerichtet ist, verformt werden kann, gemäß welchem die folgenden Schritte ausgeführt werden:
    a/ Montage mit Halten des gestreckten leitenden Elements (3) des zentralen Kontakts in dem Inneren des isolierenden Elements (5) mit Vorabeinfügen des freien Endes in den durchgehenden Schlitz (50) und mit Ausbilden mindestens eines Teils der geschlossenen Schleife;
    b/ Montage des isolierenden Elements, indem das gestreckte leitende Element gehalten wird, in dem Inneren des röhrenförmigen Körpers des ersten externen Kontakts (2) ;
    c/ Montage mit Halten des offenen Rings (4) als zweiter äußerer Kontakt um den röhrenförmigen Körper (2);
    d/ abschließendes Herstellen der geschlossenen Schleife derart, dass sie bis zu ihrer Endposition, die auf dem ersten Ende (21) des röhrenförmigen Körpers (2) ausgerichtet ist, verformt werden kann, und Gleiten des freien Endes (31) der Schleife heraus, bis es auf dem zweiten Ende (22) des röhrenförmigen Körpers (2) ausgerichtet ist, indem sie von dem isolierenden Element vorragt.
  12. Elektrische Schaltkreiseinheit, die Folgendes umfasst:
    - mindestens einen koaxialen Hyperfrequenzkoaxialanschluss (1) nach einem der vorstehenden Ansprüche,
    - zwei gedruckte Karten (6, 7), die zueinander in einem gegebenen Abstand (Hi, Hm) parallel gehalten sind, wobei jede der Karten eine erste leitende Bahn, zentrale Bahn (60, 70) genannt, und eine zweite leitende Bahn, Massebahn (61, 71) genannt, umfasst,
    wobei die Verbindung zwischen den zentralen Bahnen (60, 70) durch das gestreckte leitende Element (3) mit seiner geschlossenen Schleife (30) in einer beliebigen verformten Position bis zu seiner verformten Endposition hergestellt wird, während die Verbindung zwischen den Massebahnen (61, 71) durch den Ring (4) in einer beliebigen verformten Position bis zu der verformten Endposition hergestellt wird.
