Definitions

  • the invention relates to an RF coaxial connector part for fixed mounting to a printed circuit board, consisting of a metallic housing part with solder terminals and a metallic plug-in part in the form of a coaxial connector or a Koaxialbuchse, wherein the solder terminals in the form of solder pins from the bottom of the Stand out housing part and in which the solder pins when mounting the housing part with its bottom on the circuit board in them board side associated electrical connections in the form of contacted mounting holes intervene in which they are soldered in a Schwallötbad to the circuit board.
  • RF coaxial connector parts of this type are known, for example, from the reference SIEMENS: "HF Connectors Data Book 1990", page 4,13.
  • SIEMENS "HF Connectors Data Book 1990”
  • the underside of the housing part of the coaxial connector part must not sit well on the printed circuit board.
  • this is achieved by a so-called “offset” in the form of a one-sided approach of the solder pins for the coaxial outer conductor or the reference potential of the coaxial connector part at the bottom of its housing part.
  • EP 0 189 846 A a connector part for a coaxial cable is described in which a connector is soldered to a printed circuit board by means of solder pins which engage in corresponding mounting holes. A coaxial cable is subsequently inserted into a sleeve so that a central conductor contacts the centrally soldered conductor terminal. Furthermore, a flat collar is provided on which the solder pins are arranged frontally.
  • the invention has for its object to provide a further design solution for a coaxial connector part of the aforementioned type, which also allows a perfect soldering of the solder pins of the coaxial connector part in the contacted mounting holes of the circuit board to create good RF-tightness, but without the mentioned Offset and the related disadvantages described.
  • the invention is based on the finding that it is sufficient when soldering for a good flow of the solder through the contacted mounting holes of the circuit board with the solder pins of the coaxial connector part when the solder can emerge at least at two opposite locations of the contacted mounting holes on the top of the circuit board. This requirement is readily ensured in the use of the annular collar when the solder pins for the coaxial outer conductor or the reference potential of the coaxial connector part are arranged on the inner or outer wall of the annular collar.
  • a straight coaxial connector part has a metallic housing part, in which at the top 3, a male part 4 is inserted or screwed in the form of a coaxial connector, of which only the coaxial outer conductor 5 is visible.
  • solder pins 7 and 8 engages the housing part 2 of the coaxial connector part 1 in electrical connections performing contacted mounting holes 9 a circuit board 10 a.
  • an offset representing approach 11 is provided on the underside 6 of the housing part 2, via which the coaxial connector part 1 is seated on the circuit board 10.
  • FIGS. 2 and 3 show in various perspective views of a coaxial connector part 15, which is designed here as an angle connector part.
  • the metallic housing part 16 of this coaxial connector part 15 merges on its underside 17 into a self-contained annular collar 18.
  • the solder pins 19 for the coaxial outer conductor 5 and the reference potential of the coaxial connector part 15 protrude from the free end face 20 of the annular collar 18 and are in their length relative to the solder pin 21 for in Fig. 3 visible coaxial inner conductor 22 by the height H of the annular collar 18 shorter.
  • the protruding from the free end face of the ring collar solder pins 19 have an approximately square cross-section with a side length equal to the wall thickness W - see Fig. 5 - Of the annular collar 18 is.
  • FIGS. 2 and 3 can be seen in this design is achieved that the coaxial connector part 15, which rests on its connection with the circuit board 10 with the free end 20 of its annular collar 18 on the circuit board top 12, the contacted mounting holes 9 on the circuit board top 12 is not completely covered. Rather, the mounting holes 9 remain peripherally on two opposite sides of the solder pins 19, namely on the side of the inner and outer walls of the annular collar 18 without cover.
  • the solder can also rise unhindered from the circuit board base 14 in the mounting holes 9 up to the circuit board top 12, especially since the clearance for the solder in the round mounting holes 9 is increased by the approximately square cross-section of the solder pins 19 .
  • the contacted mounting holes 9 expediently have a diameter of 1 mm.
  • a residual gap of about 0.1 mm In united with the circuit board 10 state of the coaxial connector part 15 remains between the free end 20 of the annular collar 18 of its housing part 16 and the circuit board top 12, a residual gap of about 0.1 mm. The achieved despite this residual gap RF-tightness is in the order of 60 db. In special cases, HF-impermeability of> 100 db may be required. In this case, it is necessary to eliminate even this residual gap. In a simple way, this is possible because of the in Fig. 3 dashed lines shown on the circuit board top surface 12 ring portion 23 is designed as a soldering surface and the annular collar 18 with its free end face 20 in the terminal is soldered to the Schwallötvorgang on the circuit board 10.
  • annular groove 24 is provided in the outer wall of the annular collar 18.
  • the annular groove 24 is particularly clearly visible. It has about the same depth and width.
  • the wall thickness W of the annular collar 18 is greatly reduced to the wall thickness W1 and thus realized an effective thermal resistance.
  • the annular groove could also be provided on the inside of the annular collar. However, this would require additional measures to adjust the characteristic impedance of the coaxial line of the coaxial connector part at this point, which is avoided by attaching the annular groove on the outside of the annular collar.
  • the coaxial connector part with ring collar on the bottom of its housing part can be designed either as a straight coaxial connector part or as a coaxial-angle connector part. It can also be designed either as a coaxial plug part or coaxial socket part. For this it is, based on the in the FIGS. 2 and 3 shown coaxial connector part only required to replace the inserted into the housing part 16, a plug part performing male part 4 by a female part.
