Definitions

  • the present invention relates to a connector for HF lines according to the preamble of claim 1.
  • Connectors of the type of an insulation displacement connection which make contact with a conductor via cutting, for example to take a signal from the conductor, or to connect two conductors to one another via such a plug connection, are known. Such known connectors are used wherever it is necessary to create an inexpensive solution to establish an electrically conductive connection between the connector and the conductor.
  • the shielding of the line is generally penetrated via metal cutting edges until the cutting edges come into contact with the conductor.
  • an electrically conductive connection can be established between two lines, the shields of which are penetrated by the cutting edges of the plug connection, so that the two conductors are in electrical contact via the cutting edges.
  • a connector for HF lines has also become known in which a pair of cutting edges is arranged such that the end faces of the two cutting edges are exactly opposite one another, that is to say the pair of cutting edges is arranged in one plane with respect to the HF line.
  • Such RF lines are used where there is a large amount of data or signals to be transmitted that are of a correspondingly high level
  • Another area of application for such RF lines is automotive technology, in which large amounts of data and wave signals have to be transmitted for audio systems, multimedia applications in the field of communication or navigation.
  • the cutting edges may shift with respect to the conductor, as a result of which the contact resistance is changed and different potentials or faulty contacts may occur.
  • the signal picked up by the conductor is falsified.
  • the invention is therefore based on the object of creating a plug connector which, while basically maintaining the insulation displacement technique, permits contact with the conductor to remain unchanged even in the event of temperature fluctuations and vibrations.
  • the present invention is based on the finding that there is a cold welded connection in the insulation displacement connection between the cutting edges and the conductor and this connection is disturbed in the case of a relative movement between the cutting edges and the conductor due to the gap gap which arises between the cutting edges and the conductor. An air gap is created that changes the electrical resistance at the contact point between the cutting edges and the conductor. There are potential differences at the contact point.
  • a connector for HF lines for contacting the outer conductor of the HF line by means of an insulation displacement connection is provided with at least one pair of opposing cutting edges, in which the cutting edges are offset opposite one another in the axial longitudinal direction of the outer conductor.
  • the RF line is preferably a coaxial cable.
  • the term opposite and offset arrangement of the cutting edges is to be understood in the sense of the invention that the cutting edges are basically arranged opposite one another on the HF line, but in contrast to the known plug connector the cutting edges are not arranged end-to-end , but seen one behind the other in the axial longitudinal direction of the conductor, d. H. at a distance from each other.
  • the connector has a plurality of pairs of cutting edges that are perpendicular to one in the axial longitudinal direction of the outer conductor extending plane are arranged symmetrically.
  • Training is achieved that the RF line between the cutting edges of the connector during the manufacture of the insulation displacement connection is not subjected to a tensile force running in the axial longitudinal direction of the outer conductor and leading to shear of the line, but is slightly compressed between the cutting edges.
  • the connector may have several pairs of cutting edges, which are arranged symmetrically to a plane running along the axial longitudinal direction of the outer conductor, so that a mirror-symmetrical design of the connector is made possible for both planes, so that only one half of the connector has to be manufactured and two halves over the cutting - Which can be plugged into each other to form the connector.
  • the increased contact area between the cutting edges and the conductor causes the cutting edges to slide on the outer conductor when the distance between their end faces is changed, without forming a gap between the outer conductor and the cutting edges, since the sliding surface is largely formed by the side surface of the respective cutting edge.
  • Fig. L in a perspective view of a known connector
  • Fig. 2 shows the connector of Figure 1 in a schematic representation from the side.
  • Figure 3 shows a connector according to the invention in a perspective view.
  • FIG. 4 shows the connector according to FIG. 3 in a schematic see representation from the side
  • Fig. 5 is a front view showing how the outer conductor is clamped between the cutting edges of the connector.
  • Fig. 1 and Fig. 2 of the drawing show a known connector 1 with cutting edges 2, which are arranged face to face on the end.
  • the connector 1 has a largely rectangular base plate 4, on the longitudinal sides of which tabs 5 are formed, so that the connector 1 has a U-shaped configuration in a view from the front.
  • the two legs of the U-shaped arrangement formed in this way are formed by the tabs 5 which surround the HF line 3.
  • the cutting edges 2 of the connector 1 each run in one plane, so that the outer conductor 8 clamped between the cutting edges 2 is only grasped by the respective end faces of the cutting edges 2, so that it is at a change in the distance between the cutting edges 2, for example due to a temperature fluctuation, leads to a gap in the contact area between the cutting edges 2 and the outer conductor 8 and potential differences or faulty contacts result.
  • FIG. 3 and 4 of the drawing show a plug connector 9 according to the invention, which is largely similar to the known plug connector 1 and can therefore be clamped in an advantageous manner with an already existing tool.
  • Tabs 5 extend from the base plate 4 of the connector 9 to form a largely U-shaped configuration of the connector 9 and encompass the HF line 3.
  • the tabs 2 extend from the tabs 5 at an angle substantially at right angles to the axial longitudinal direction of the conductor 3 Direction to the inner conductor 6 (see FIG. 5) and penetrate the outer insulation 7 of the conductor 3 and clamp and squeeze the outer conductor 8.
  • the connector 9 has on the long sides of its base plate 4 two tabs 5, which have pairs of blades with different axial distances a, b of the blades 2.
  • the connector 9 can be composed of two halves, with a half made from a sheet metal part being assembled with another half to form the connector 9 can be arranged by overlapping the pairs of cutting edges.
  • the tabs 5 have receptacles 12 which can engage and engage in the locking lugs 13 of the other connector half.
