Definitions

  • the invention relates to the connection of two energy conduits by interlocking into one another.
  • conduits for transporting microwave electromagnetic signals such as coaxial cables.
  • connection devices between, for example, two coaxial cables, or between a coaxial cable and a printed circuit board, or even between a coaxial cable and a microwave device comprise two parts, or connectors, suitable for connection and which , each one, must respect electrical characteristics in order to limit the alteration of the transmitted signal.
  • These electrical characteristics, for the frequency band in which these connectors must operate, are notably the standing wave ratio, the characteristic impedance and the insertion losses. They must be preserved whatever the relative position of the two connectors.
  • the connectors comprise shouldered cylinders of various diameters fitted concentrically and rigidly into each other.
  • This internal geometry which results from both complex calculations and extensive experimentation, combined with the nature of the dielectric present inside these connectors contributes to obtaining the required electrical characteristics, and the rigid fitting of the various cylinders makes it possible to avoid any variation in these characteristics.
  • Their production and their operating condition therefore make it necessary to present them almost facing one another in order to couple them, and, once the coupling has been carried out, it is practically no longer possible to move a connector transversely with respect to to the other due to the rigid and tight fitting of these.
  • the connectors employed must be able to accept, after being coupled, transverse displacement without significant alteration of their electrical characteristics.
  • the main object of the present invention is to provide a solution to this problem.
  • An object of the invention is to provide a connection device allowing relative movement of the parts connected by interlocking, along an axis perpendicular to the interlocking axis.
  • Another object of the invention is to allow the coupling of the two parts in a given initial position as well as their uncoupling in this position or else in the position obtained after relative displacement.
  • the object of the invention is also, in particular in the case of transmission of electromagnetic signals, in particular microwave, to preserve the nature of the electrical contacts within the connection device as well as not to significantly alter the performance of this device regardless of the relative position of the two parts.
  • the present invention therefore relates to a connection device comprising a first hollow part, opening at one end, and adapted to be inserted along an interlocking axis in a second hollow part also opening at one end; these two hollow parts can for example be connected on the other hand respectively to two conduits for transporting electromagnetic signals, in particular microwave.
  • Each hollow part has a side wall and, when the first part is fitted into the second, the external face of the side wall of this first part is connected to contact via a first connection zone, on a second zone connecting the internal face of the side wall of the second part; these two connection zones are able to fit into two cylinders whose generatrices are substantially parallel to each other and to the interlocking axis;
  • the term "cylinder” here refers very generally to any surface generated by a straight line, or generative, moving parallel to a fixed direction by relying on a fixed plane curve, or director, whose the plan cuts the given direction.
  • a cylinder can either be of revolution, the directrix then being a circle, or else a prism with a polygonal base.
  • the second connection zone comprises two flats, symmetrical with respect to a nesting plane containing the axis nesting; in addition, the internal face of the side wall of the second part as well as the external face of the side wall of the first part are shaped with a clearance contained in the interlocking plane and substantially perpendicular to the generatrix of the cylinders, which thus allows relative movement of the two parts along an axis perpendicular to said generator and contained in the nesting plane, while preserving contact between the two faces.
  • the invention starts from the observation that the geometrical characteristics of the two side walls thus defined will make it possible, with suitable arrangements, to provide a solution to the problem posed.
  • the cylinders in which the connection zones are inscribed have the same longitudinal axis of symmetry contained in the interlocking plane.
  • this first hollow part comprises a first internal cylindrical stud, substantially parallel to the wall and separated from the internal face of this wall by a dielectric;
  • the second hollow part also comprises a cylindrical internal stud, substantially facing the internal stud of the first hollow part and also separated from the internal face of the wall of this second hollow part by a dielectric.
  • One of the studs then advantageously comprises a housing opening, having two flats substantially symmetrical with respect to the axis of symmetry of the stud and suitable for being connected by interlocking and electrical type contact on the other internal stud, the two internal studs being shaped with a parallel and at least equal clearance the play of the internal and external faces of the side walls of the two parts in contact.
  • connection device has references assigned a suffix equal to the number of the embodiment described. Elements which are analogous or have an analogous function in several embodiments have the same reference. When these elements are mentioned in general, the suffixes corresponding to the various embodiments are deleted.
  • connection device is interposed between an electrical conductor capable of carrying microwave signals, and a printed circuit board.
  • this electrical conductor is a coaxial cable carrying signals in a frequency band extending up to 40 GHz.
  • connection device comprises two connectors suitable for fitting one into the other.
  • the first of them has a first hollow part 1, opening at one end, and connected at its other end to a housing 4 provided with two pins 5 capable of being soldered on the printed circuit.
  • the second connector comprises a second hollow part 2 also opening at one end, and connected to its other end to the coaxial cable 3.
  • the first hollow part 1 has a first cylindrical side wall 10 having a longitudinal axis of symmetry 6. This side wall is split longitudinally by slots 13, which thus gives it a certain transverse elasticity.
  • the second hollow part 2 also has a cylindrical side wall 20, having the same longitudinal axis of symmetry as that of the side wall of the first hollow. This axis of symmetry thus constitutes the interlocking axis of the two connectors.
  • the internal face 201 of this side wall 20 comprises two parallel longitudinal flats 202, 203, arranged symmetrically with respect to a plane containing the interlocking axis, called the interlocking plane.
  • the material of the side walls of the two hollow parts is an electrically conductive material with elastic properties; it may for example be stainless steel, a copper alloy which may be based on berrylium, coated or not with precious metal.
  • the external face 100 of the side wall 10 of the first hollow part comprises, in the vicinity of its free end, ribs 11 projecting and intended to come into contact on the two flats of the internal face 201 of the side wall of the second hollow part.
  • these ribs are part of a first connection zone while the flats are part of a second connection zone.
  • the external face 100 of the side wall of the first hollow part and the internal face 201 of the side wall of the second hollow part are shaped with a clearance j contained in the interlocking plane and substantially perpendicular to the axis of interlocking 6. This play then allows a relative movement of the two connectors along the axis 7 perpendicular to the interlocking axis 6. Of course, this play is at least equal to the maximum relative movement desired for the two connectors.
  • the first hollow part 1 also comprises a first cylindrical internal stud 12 whose longitudinal axis of symmetry is substantially coincident with the interlocking axis 6.
  • This internal stud 12 is open and split longitudinally so as to provide two other flats 120, 122, symmetrical to one another, and defining a housing 122 also having a certain elasticity.
  • This internal stud 12 is separated from the internal face 101 of the side wall 10 by a dielectric 9 which here is air.
  • the second hollow part 2 also includes an internal cylindrical stud 22, the longitudinal axis of symmetry of which is substantially coincident with the interlocking axis.
  • This internal stud 22 is therefore capable of being inserted into contact in the housing 122 of the internal stud 12 so as to ensure the electrical continuity of the internal conductor of the cable 3.
  • These two internal studs are also shaped with a play js parallel and at least equal to the game j.
  • FIGS. 1A to 1C describe the first embodiment of the device according to the invention.

  • This side wall 10-2 also includes an upper plate 104-2 and a lower plate 105-2, the four plates of this side wall then forming a rectangular parallelepiped whose axis of symmetry is the interlocking axis 6-2 .
  • Each side plate 102-2 and 103-2 has a rib extending transversely at its free end.
  • the side wall 10-2 has four slots 13-2 formed over most of its length at the intersection of each of the four plates.
  • the internal stud 12-2 is identical to the internal stud 12-1 in the first embodiment.
  • the two upper and lower plates 104-2 and 105-2 are not really essential.
  • the first hollow part only comprises the two side plates coming into contact with the two flats of the second hollow part.
  • the nature of the dielectric as well as the geometric characteristics of the connection device are such that the electrical characteristics of the type of those mentioned above. front are substantially identical regardless of the position of the first hollow part relative to the second hollow part.
  • the two parts can be coupled or uncoupled whatever their relative position.
  • the device according to the invention also makes it possible, for example, to connect a two-wire shielded cable to a printed circuit board, that is to say a cable having an outer conductor surrounding two inner conductors.
  • a connection device is illustrated in FIGS. 3A and 3B.
