Definitions

  • the invention relates to the connection between a printed circuit board and a coaxial cable.
  • a solution according to Figure 2 is known in the art, in which the inner conductor 30 of the coaxial cable 3 is inserted into a corresponding bore 20 on the printed circuit board 2 and soldered.
  • the ground connection is created by baring the shield 32 of the coaxial cable 3 above the printed circuit board, twisting it together into a cord and inserting and soldering it into a corresponding bore 21 for the ground connection on the printed circuit board.
  • Another construction which is known in the art provides first of all for a cable to be soldered onto the shield and then to be inserted and soldered with its other end in the printed circuit board.
  • both variants have the disadvantage that the coaxial cable is not shielded above the printed circuit board over a relatively long length, which has a disadvantageous effect on the transmission properties.
  • the object of the invention is to create a connection between coaxial cable and printed circuit board which has better transmission properties and improved mechanical stability than the known solutions described above.
  • a cable adapter for the connection between a printed circuit board and a coaxial cable which has only an ground pin and means for receiving the coaxial cable, the receiving means being constructed in such a way that the inner conductor of the received coaxial cable is spaced from the ground pin so that - when the cable adapter is assembled - the inner conductor and the ground pin can be inserted into two correspondingly spaced pin holes on the printed circuit board and then will be soldered.
  • the unshielded region of the coaxial cable can be reduced to a minimum, resulting in corresponding improvement in the transmission and crosstalk properties. Moreover, reproducible connections with high mechanical stability can be created with the cable adapter.
  • a cable adapter 1 according to a first embodiment is shown which serves as connection between a printed circuit board 2 and a coaxial cable 3.
  • the cable adapter 1 has in particular an ground pin 10 and means 11 for receiving the coaxial cable 3, the receiving means 11 being constructed in such a way that the inner conductor 30 of the received coaxial cable 3 is spaced from the ground pin 10, so that - when the cable adapter 1 is assembled - the inner conductor 30 and the ground pin 10 can be inserted into to correspondingly spaced pin holes 20, 21 on the printed circuit board 2.
  • the cable adapter 1 is also provided with a support surface 12 with which it is supported on the printed circuit board 2 and which enables vertical fitting of the cable adapter on the printed circuit board, the support surface is advantageously provided in the region of the ground pin 10.
  • the ground pin projects approximately centrally and vertically out of the support surface 12.
  • the means 11 for receiving the coaxial cable 3 are constructed as a sleeve with a through bore 13 into which the coaxial cable 3 can be inserted.
  • the through bore 13 has a first region 13a with a first diameter and a second region 13b with a smaller second diameter.
  • the coaxial cable consists in a known manner of an inner conductor 30, a dielectric 31, a shield 32 and a jacket 33.
  • the two regions 13a, 13b of the through bore 13 are dimensioned in such a way that the first diameter of the first region 13a is slightly greater than the diameter of the shield and the second diameter of the second region 13b is slightly greater than the diameter or the dielectric 31.
  • the coaxial cable 3 is prepared in accordance with Figure 1 so that the end or the coaxial cable 3 is formed by a bared inner conductor 30, the length of the bared inner conductor being somewhat greater than the thickness of the printed circuit board 2.
  • the inner conductor 30 is cladded with the dielectric 31 which, when the cable adapter 1 is assembled, extends from the beginning of the second region 13b as far as the surface of the printed circuit board.
  • the shielding is still present. Outside the cable adapter 1 the coaxial cable also still has the jacket 33.
  • the receiving means 11 For fixing the coaxial cable 3 in the cable adapter 1, the receiving means 11 have a transverse bore 14 which opens in the first region 13a of the through bore 13. Thus the transverse bore 14 opens in the region in which the shield of the coaxial cable 3 is bared. Thus by way of this transverse bore 14 the coaxial cable 3 can be soldered to the cable adapter 1.
  • the cable adapter 1 is advantageously produced in one piece from electrically conductive material, and between the receiving means 11 and the ground pin 10 there is provided a transverse piece 15, at one end of which the ground pin 10 extends perpendicular thereto in one direction and at the other end the receiving means 11 extend perpendicular thereto in the other direction.
  • the cable adapter 1 With the support surface 12 provided in the region of the ground pin 10 the cable adapter 1 is supported on the printed circuit board 2 in such a way that between the printed circuit board 2 and the opposing end of the receiving means 11 a slot with a defined slot height a remains. This slot ensures that the soldering does not cause a short circuit between inner conductor 30 and ground.
  • the size of the support surface 12 with which the cable adapter 1 is supported on the printed circuit board 2 is advantageously at least 25%. preferably at lest 30% of the total area of the cable adapter, as can be seen from Figure 5. In this way it can be ensured that by light pressing the cable adapter 1 can be vertically aligned above the support surface and can be soldered on in this position.
  • the slot height a is fixed by the geometry of the cable adapter 1 and can be reproduced again and again during soldering.
  • the connection impedance of the connection can be adapted for example to 50 ⁇ for a specific application.
  • the cable adapter 1 illustrated in Figures 1, 3, 4 and 5 is produced as a turned/milled part.
  • FIGs 7 and 8 shows a cable adapter according to a second embodiment which has been produced as bent sheet material part from a flat material blank (see Figure 6).
  • Figures 7 and 8 shows a cable adapter according to a second embodiment which has been produced as bent sheet material part from a flat material blank (see Figure 6).
  • the same reference numerals are used for equivalent components.
  • This cable adapter also consists of only an ground pin 10 and means 11 for receiving the coaxial cable which are constructed in such a way that the inner conductor of the received coaxial cable is spaced from the ground pin so that - when the cable adapter is assembled - the inner conductor and the ground pin can be inserted into two correspondingly spaced pin holes on the printed circuit board.
  • the through bore 13 has no inner graduation. Nevertheless a lateral opening corresponding to the transverse bore 14 is provided, via which the inserted coaxial cable can be soldered to the receiving means 11.
  • the cable adapter illustrated in Figures 6, 7 and 8 should be regarded merely as an example. Especially when it is produced as a bent sheet material part a large number of variants are conceivable.
  • a significant aspect is also again the construction of a support surface 12, which makes possible a defined vertical alignment of the cable adapter on the printed circuit board 2.
  • the support surface 12 is formed by two clips which are bent in opposite directions (see Figure 8). Also in this embodiment in the assembled state of the cable adapter a slot with a slot height a remains between the printed circuit board and the lower end of the receiving means 11.
  • the cable adapter according to the invention can also be produced by transfer moulding or sintering.
  • the cable adapters according to the invention have substantially better transmission and crosstalk properties than the known solution according to Figure 2.
  • S21 parameter transmission measurement
  • the cable adapter offers a substantially higher stability of the cable/printed circuit board connection, so that bending or breaking of the cable can be avoided.
  • the means for receiving the coaxial cable also act as shielding in the region where the dielectric 31 is exposed, so that it is only in the region of the slot between the means 11 and the printed circuit board 2 that there is no shielding.
  • the substantially improved shielding which results from this by comparison with the embodiment according to Figure 2 also results in a lower inductance of the connection.
