Definitions

  • the invention relates to an antenna system, in particular for a vehicle, comprising a printed circuit board and an antenna support having at least one electrically conductive structure for transmitting and / or receiving high-frequency signals, wherein the at least one electrically conductive structure via a crimp with crimped blades with a conductor of the circuit board electrically is contacted, according to the features of the preamble of claim 1, and generally a crimped connection.
  • Such antenna systems in which electrically conductive structures form antenna structures which are arranged on an antenna carrier, for example a plastic film, and in which the at least one electrically conductive structure with an electronic device, the printed circuit board with a conductor thereon, which is a point of contact forms, are known.
  • the antenna carrier with the antenna structures can, for example, be arranged plane-parallel to a vehicle window (for example in the region of the black print) visible or invisible, whereby the electrical contact with the electronic device, for example a frequency converter, a matching network, an amplifier or the like, takes place the electronic device is housed in a suitable space in the vehicle.
  • the materials used for the antenna carrier and for the electronic device are different from each other, so it is necessary to separately produce the antenna carrier with the conductive structures on the one hand and the electronic device with its printed circuit board on the other hand.
  • a crimp connector For electrical contacting of an antenna structure on an antenna carrier with an associated contact point of a conductor track on a printed circuit board of the electronic device, a crimp connector has already become known. Such a crimp connector used in a corresponding antenna system is shown in the prior art in FIG.
  • Figure 1 shows an antenna system 1 with a printed circuit board 2 of an electronic device, not shown, wherein on the circuit board 2 a likewise not shown conductor track or a contact point of such a conductor path is present.
  • an antenna support 3 is manufactured and arranged, wherein on the antenna support 3 not shown electrically conductive structures forming antenna structures are applied.
  • a crimp 4 is used to the electrically conductive structure, in particular whose end region to be able to connect to the contact point of the conductor track of the printed circuit board 2 of the electronic device.
  • This known crimp connector 4 has Crimperiel 5 (here four Crimperiel 5) and in the axial extent a Lötfahne 6.
  • the crimp 4 is stung by means of a special press through the antenna support 3 and then mechanically deformed the Crimperiel 5 in the region of the electrically conductive structure or in the region of the contact point.
  • a crimp connector 4 is shown in the undeformed state and in the right-hand part of FIG. 1 in the deformed state, wherein it can be seen that the crimp wings 4 are unbent in the direction of the electrically conductive structure, so that this region is not only mechanical set, but also contacted electrically.
  • a soldering lug 6 of the crimp connector 4 is required, which considerably increases this crimping connector 4.
  • the crimp connector 4 stands out clearly by means of this solder tail 6 at the edge of the printed circuit board 2 (board edge) or has a difficult repeatable distance to the printed circuit board 2 in the case of mass production of antenna systems.
  • These properties in particular limit the possible applications in a good high-frequency design for such an antenna system disadvantageous, because it is particularly important here that no impedance jumps are present in the supply line, since such impedance jumps generate reflections, which leads to a loss of power and this in turn to a significantly deteriorated performance of the antenna system.
  • the crimp connector 4 is soldered after deformation with the Lötfahne 6 with the contact point on the circuit board 2, so that special temperature characteristics of the antenna carrier 3 are required.
  • This process is a further processing step, which costs time and money, since the antenna support 3 must either be made of high temperature resistant material and / or shielded against the soldering in an appropriate manner. It is therefore an object of the invention to improve a generic antenna system with respect to its mechanical structure, thereby simultaneously improving the performance characteristics of the antenna system. In addition, an improved crimp connection is to be provided for use in an antenna system, but also for applications beyond that.
  • the crimp connector is soldered onto the conductor track of the printed circuit board (without having the known solder tail) and that the electrically conductive structure in the contact region with the crimp connector is arranged approximately plane-parallel to the printed circuit board.
  • a Crimperieln crimp is provided, which is mounted on the circuit board and soldered to the electrically conductive structure of the circuit board.
  • the crimp connector can be soldered in a simple manner to the printed conductor (or to a contact point of the printed conductor specially designed for this purpose). This can be done either individually by hand or in a particularly advantageous manner in a solder bath.
  • the crimp connector is designed as an SMD crimp connector, so that the SMD technology (surface-mounted device technique) can be used. This offers itself from all things in the series production of such antenna systems or in general for the realization of crimp connections. This soldering is done in an advantageous manner completely independent of the antenna carrier, so that it does not have to have high temperature properties.
  • the region of the electrically conductive structure to be contacted with the crimping connector is arranged approximately plane-parallel to the printed circuit board and by deformation the Crimperiel mechanically fixed and contacted at the same time.
  • This crimp connection is a highly durable and long-lasting reliable contact that has been tried, so that thereby the electrically conductive structure is reliably and permanently connected to the associated contact point of the circuit board of the electronic device.
  • a further advantage of this solution is the fact that the impedance in the contact region is favorably and purposefully influenced by the degrees of freedom, such as the different thicknesses of the antenna carrier and / or printed circuit board and the materials used for the electrically conductive structures and the conductor track, as well as the materials and geometries of the crimp connector can be.
  • This design has the decisive advantage that, if at all, only a few transition losses occur and the impedance jumps that are disadvantageous in the prior art are either completely or largely avoided, thereby significantly increasing the performance of the antenna system.
  • a plurality of crimp connectors are arranged side by side on the printed circuit board.
  • a plurality of electrically conductive structures are arranged on the antenna carrier in a corresponding manner. This can be done in a simple manner by bringing the antenna carrier with the on the circuit board arranged Crimpsteckverbindern fast, easy and efficient contact can be achieved.
  • the antenna carrier overlaps with one of its longitudinal sides at least partially, in particular completely, the printed circuit board. Due to this layer construction, contacting of several crimp connectors with a plurality of antenna structures results in a good contact with good impedance matching at the same time, so that even with more than one antenna structure no or only little transition loss occurs on the antenna support.
  • a contact point of the electrically conductive structure is arranged on a tab projecting from a longitudinal side of the antenna carrier and contacted electrically by the crimp connector.
  • a contacting of a crimp connector with a contact point on a tab takes place one after the other, whereas when the contact points or end regions of the antenna structures are guided to the side area of the antenna carrier, contacting of all contact points of the antenna structures with the crimp connectors occurs simultaneously the printed circuit board of the electronic device takes place when this side area of the antenna carrier overlaps placed on the side region of the circuit board and moved plane-parallel to each other.
  • the antenna carrier recesses for the implementation of the Crimpulatel of the crimp in the not yet deformed state. This means that recesses are punched in the antenna support, for example, through which the crimps projecting upwards from the printed circuit board are carried out when a side region of the antenna support is moved in an overlapping plane parallel to the surface of the printed circuit board. This facilitates the process of bringing together and, moreover, the crimps have sufficient space and are not disturbed by material of the antenna carrier during deformation.
  • the antenna carrier is suitable and designed for piercing the crimping prong of the crimp connector in the not yet deformed state.
  • geometry and material properties of both the Crimperiel and the antenna carrier must be coordinated so that when the tips of Crimperiel the antenna carrier to pierce (possibly with the aid of a press or a punch) still no deformation or only a very minor Deformation of the Crimperiel takes place, so that they are then purposefully deformed for the purpose of mechanical fixation and electrical contacting.
  • the antenna carrier is a plastic film.
  • plastic film has the advantage that it can be easily and simply provided with the electrically conductive structures (for example by an imprinting process), at the same time can be adapted to the geometry in the installation space (or the installation surface) and also puncture the crimping prongs or ., the punching for the recesses for the implementation of Crimperiel realized easily.
  • the plastic film may be plastically or thermally deformed in order to adapt it to the contact area on the printed circuit board and / or the installation space of the conductor structure arranged on the antenna carrier preferably before or during or even after installation.
