  • Coaxial high-frequency connector for connecting numerous coaxial lines
  • the invention relates to a coaxial high-frequency connector for the connection of numerous coaxial lines in which the plug connections of the coaxial lines are arranged directly adjacent in a row, with the features of the types described in the preambles of claims 1 and 2.
  • Coaxial connectors for high-frequency technology are known per se.
  • Coaxial connectors for connecting numerous coaxial lines are required, for example, in transmission technology.
  • signal speeds for coaxial lines in the HF range are achieved with up to 93 percent of the speed of light.
  • an essential requirement is to prevent crosstalk between neighboring lines as much as possible. So far, with coaxial cables directly next to each other, a lower grid spacing of 2.54 mm for the individual cables has been achieved for the plug connections. So far, all signal lines and the associated ground lines have been connected purely manually.
  • Conventional soldering technology is usually used as the connection technology. Due to the closely adjacent signal and ground wires, the soldering process easily leads to short circuits and thus to errors in the connector structure.
  • the coaxial shielding effect of the coaxial lines is also disturbed or interrupted by the separation of signal and ground lines for connection on the adjacent contact points.
  • the juxtaposition of the signal or ground wires of the numerous coaxial lines lying next to each other on the contact points of the connector then leads to additional errors in the contacting if the signal lines and the ground lines are not fully seated on the contact point, as is the case, for example, with high-frequency coaxial lines is whose signal and ground lines consist of thin wires or strands that have resilient properties.
  • Such sources of error must be eliminated by means of an appropriate control and by a time-consuming repair process.
  • the invention is therefore based on the object of creating a simple and inexpensive high-frequency plug connector suitable for mass production, which in particular permits automatic and mechanical connection of numerous coaxial lines simultaneously and which achieves the narrowest latching distances for the connection of a plurality of coaxial lines enables the connection of the coaxial lines to the individual plugs while maintaining the coaxial shielding effect of each individual coaxial line for the respective signal line.
  • the advantages of the invention are in particular that a common intermediate support is provided for the base housing.
  • the basic housing is used to connect the intended number of individual coaxial lines to the high-frequency connector.
  • These recesses are thus designed to be radio-frequency-tight, ie the base housing made of electrically insulating material for guiding the signal lines is surrounded by a complete electrical shield for each individual coaxial line, which ensures perfect coaxial behavior.
  • the recesses described can be arranged very closely next to one another, if this is done, for example, in a line-like manner or in a line-like continued block with openings for the base housing, so far not possible close spacing of signal lines reach individual coaxial lines.
  • the latching distances of 2.54 mm between two signal lines known from the prior art can be at least halved.
  • the coaxial lines consisting of strands or thin wires, e.g. used in multi-core round cables, in the state of the art often led to positioning errors at the contact points due to their elasticity and their resilient properties.
  • centrally arranged through holes are provided for the signal lines in the subject matter of the invention, with each through hole being preceded by a run-in phase in the form of a funnel-shaped expansion of the through hole.
  • This funnel-shaped extension practically always ensures that the signal wires are guided.
  • This bore with a funnel-shaped extension also makes it possible to correctly position resilient or slightly elastic signal lines at the connection point when they are inserted mechanically into the running-in phase.
  • this funnel-shaped extension provides passive tolerance compensation, which in turn can also compensate for positioning inaccuracies.
  • the multiple coaxial plug connectors according to the invention are also equipped with features in order to be able to connect the combined ground shielding lines or possibly both wires also automatically and mechanically for each of the adjacent coaxial lines at the same time.
  • the coaxial high-frequency connector for each individual ground contact of the numerous coaxial lines is equipped with one bendable tab on the overall housing per ground line.
  • the correspondingly curved and supplied individual ground lines of the numerous coaxial lines automatically lie on the correspondingly designed tab of the overall housing wall when the base housing already connected to the signal contact is inserted.
  • the pre-bent ground lines of the individual coaxial lines lie exactly on the correspondingly pre-bent tabs of the overall housing wall and can now be fitted by suitable means Connect soldering devices electrically to one another.
  • the automated connection options for the signal lines and the ground lines of the coaxial lines arranged next to one another only enable the tasks to be solved for the coaxial radio-frequency connector according to the invention.

Abstract

Dans un connecteur coaxial haute fréquence à fiches pour la connexion d'une pluralité de lignes coaxiales, les connexions des lignes coaxiales sont placées les unes à côté des autres en une rangée et sont enfermées dans un boîtier commun. Chaque ligne coaxiale individuelle est raccordée à un boîtier de base et les boîtiers de base sont à leur tour montés dans des supports intermédiaires communs. Les supports intermédiaires sont enfermés dans le boîtier commun. Des ouvertures ou des évidements ménagés dans les supports intermédiaires proprement dits ou dans les supports intermédiaires et le boîtier commun servent au montage des boîtiers de base, qui sont montés coulissants dans ces évidements ou ouvertures. Comme les parois des ouvertures ou des évidements sont électroconductrices, un espace étanche aux hautes fréquences est crée pour la connexion des lignes coaxiales et du connecteur. Toutes les pièces du connecteur coaxial haute fréquence peuvent être montées de manière automatique par des machines. En outre, ce connecteur coaxial haute fréquence à fiches permet d'obtenir une grille de dimensions particulièrement réduites entre les lignes de signalisation pour le montage des lignes coaxiales individuelles.
