Definitions

  • the invention relates to an outer conductor assembly for an electrical connector, having a first interface for electrical and mechanical contacting of an outer conductor of a corresponding electrical mating connector and a second interface for electrical and mechanical contacting of metallized recesses of an electrical assembly, according to the preamble of claim 1.
  • the invention also relates to an electrical connector.
  • the invention also relates to an electrical connection arrangement, having an electrical connector and an electrical assembly, in particular an electrical circuit board.
  • electrical connectors are known from electrical engineering. As is known, electrical connectors are used to transmit electrical supply signals and / or data signals to corresponding electrical mating connectors.
  • a plug connector or mating plug connector can in particular be a plug, a printed circuit board plug, a built-in plug, a socket or a coupling.
  • the term "connector” or “mating connector” used in the context of the invention is representative of all variants.
  • a plug connection must withstand high loads, for example mechanical loads, and remain closed in a defined manner so that the electrical connection is not unintentionally separated, for example during operation of the vehicle. Ensuring safety is a priority, especially when it comes to the autonomous operation of vehicles and driver assistance systems.
  • An electrical connector often has an outer conductor assembly, in particular for the electromagnetic shielding of the signal transmission and for the transmission of a reference voltage between the mating connector and the electrical assembly as a contribution to the signal transmission.
  • the quality of the electromagnetic shielding and in particular the contact resistance between the outer conductor assembly and the electrical assembly define in a not inconsiderable way the electrical properties of the entire connector and its usability for the transmission of high-frequency electrical signals.
  • the maximum press-in pressure that can be supplied is limited in order to avoid the formation of cracks and breaks in the electrical assembly, in particular an electrical circuit board. For this reason, a defined minimum distance between two adjacent press-fit pins should not be undershot. The smallest possible distance between the press-fit pins is, however, desirable in order to provide a high shielding effect and a low contact resistance, in particular if the plug connector is to be used for the transmission of high-frequency electrical signals.
  • the object of the present invention is to provide an outer conductor assembly which offers a particularly high shielding effect, especially in the transition area to an electrical assembly, and which is preferably economical to manufacture and easy to assemble as part of mass production.
  • the present invention is also based on the object of providing an electrical plug connector which offers a particularly high shielding effect, in particular in the transition area to an electrical assembly, and which can preferably be manufactured economically and easily assembled in the context of mass production.
  • the object is achieved for the outer conductor assembly with the features listed in claim 1. With regard to the electrical connector, the object is achieved by the features of claim 8. With regard to the electrical connection arrangement, the object is achieved by claim 12.
  • the outer conductor assembly for an electrical connector is provided.
  • the outer conductor assembly has a first interface for electrical and mechanical contacting of an outer conductor of a corresponding electrical mating connector and a second interface for electrical and mechanical contacting of metallized recesses of an electrical assembly.
  • the second interface has a plurality of contact elements for contacting the electrical assembly.
  • the outer conductor assembly is preferably made in one piece, but can optionally also be made in several parts.
  • the outer conductor assembly can optionally have a spring cage adjacent to the first interface for connection to the outer conductor of a corresponding mating connector.
  • the outer conductor assembly is preferably formed entirely from an electrically conductive material. In principle, however, the outer conductor assembly can also have electrically insulating components, for example seals and / or latching elements made of plastic.
  • the outer conductor assembly is preferably designed to electromagnetically shield connector components of the electrical connector.
  • the outer conductor assembly is preferably also designed to provide an impedance-controlled electrical transition between the electrical assembly and the mating connector.
  • the outer conductor assembly can be formed partially, essentially or preferably completely from a metal, preferably a sheet metal.
  • the first interface can be formed in particular in the area of the “front” end of the outer conductor assembly or in the area of the front end of the electrical connector equipped with the outer conductor assembly.
  • the second interface can in particular in the area of the "rear” end of the outer conductor assembly or in the area of the rear end of the equipped with the outer conductor assembly electrical connector be formed.
  • the two interfaces can preferably be arranged at opposite ends (along the longitudinal axis or central axis) of the outer conductor assembly or of the electrical connector equipped with the outer conductor assembly.
  • the outer conductor assembly is preferably designed in the form of a sleeve in order to suitably encase plug connector components of the electrical plug connector that are to be shielded electromagnetically.
  • the outer conductor assembly can have a straight, curved or angled course, in particular also a right-angled course for use in an angled connector.
  • a first group of the contact elements is designed as press-fit pins (also known by the term “press-fit pins”) for an interference fit in the metallized recesses of the electrical assembly.
  • This press-fit technique is known in particular as a connection technique in the field of electrical circuit boards and has proven itself to produce solder-free electrical connections.
  • the outside diameter of the press-fit pins is slightly larger than the inside diameter of the metallized recesses.
  • the “overpressing” that occurs during the press-in process can be absorbed by the deformation in the recess and / or by the deformation of the press-fit pin.
  • the force that has been built up creates a cohesive, cold-welded or gas-tight connection.
  • the use of the interference fit to connect the electrical connector to the electrical assembly can be advantageous because, for example, there is no thermal load on the components involved.
  • the press-fit connections can also be made very quickly and easily.
  • the gas-tight connection can lastingly counteract the aging and corrosion of the connector.
  • a second group of the contact elements be designed as spring-loaded contact elements for insertion into the metallized recesses of the electrical assembly.
  • the spring-loaded contact elements are preferably designed in the form of angled contact feet or spring tabs.
  • the spring-loaded contact elements can be angled and protrude laterally from the outer conductor assembly at least in sections.
  • the spring-loaded contact elements preferably do not run coplanar with the wall of the outer conductor assembly.
  • the number or density of contact elements can advantageously be increased without assembly-related damage or breakage of the electrical assembly, such as an electrical circuit board to risk. Due to the increased density of contact elements or the reduction in the minimum distance between the contact elements, the shielding effect of the outer conductor assembly can finally be increased sufficiently and the contact resistance can be reduced in order to provide an electrical connector for the transmission of high-frequency electrical signals. Furthermore, an impedance-controlled transition between the outer conductor assembly and the electrical assembly can be provided.
  • the outer diameter of the press-fit pins are preferably larger than the inner diameter of the metallized recesses of the electrical assembly in order to enable the interference fit.
  • the outer diameter of the spring-loaded contact elements are preferably smaller than the inner diameter of the metallized recesses of the electrical assembly. Because the spring-loaded contact elements can be inserted into the metallized recesses without any significant expenditure of force, the electrical assembly is mechanically relieved. At the same time, the bias of the spring-loaded contact element creates a mechanically and electrically secure connection between the outer conductor assembly and the electrical assembly.
  • the press-fit pins can have an insertion section at their free ends, the outer diameter of which is smaller than the inner diameter of the metallized recesses. It can be provided that the cross section of the press-fit pin widens starting from the insertion section. This can facilitate the insertion of the press-fit pin. In addition, the press-in pressure required for pressing the press-in pin into the recess can increase steadily during the press-in process, which can further reduce the mechanical stress on the components involved.
  • the press-fit pins are made longer than the spring-loaded contact elements, are preferably made at least 10% longer, particularly preferably are made at least 20% longer, very particularly preferably are made at least 50% longer and even more preferably at least are trained 100% longer.
  • the press-fit pins have an elastic deformation zone at least along a section of their longitudinal axis.
  • the deformation zone is preferably formed by a central material recess.
  • the press-fit pins can in particular have an elongated material recess or a slot oriented along the longitudinal axis of the press-fit contact, preferably in the manner of the eye of a needle.
  • the material recess does not extend completely through the material of the press-fit pin, but is designed, for example, only as a recess or groove, for example also as a recess on both sides.
  • a plurality of material recesses can also be provided, which are preferably arranged distributed along the longitudinal axis of the respective press-fit pin.
  • press-fit pins do not have any deformation zone, but instead are solid.
  • the second interface is formed on an end section of a sleeve-shaped circumferential wall of the outer conductor assembly facing the electrical assembly.
  • the contact elements preferably extend, starting from the end section, in the direction of the assembly.
  • the contact elements preferably run in an extension of the wall of the outer conductor assembly.
  • the contact elements are preferably arranged in a ring shape, for example rectangular, oval or round, in the region of the second interface.
  • the contact elements are arranged distributed along the circumference of the sleeve-shaped circumferential wall.
  • the contact elements are preferably arranged symmetrically and / or uniformly or equidistantly distributed.
  • the contact elements can be arranged distributed along the circumference, preferably axially symmetrically. A point-symmetrical arrangement can, however, also be provided. In addition, an equidistant distribution of the contact elements can be particularly suitable, with a non-equidistant distribution also being able to be provided in individual cases.
  • At least one of the spring-loaded contact elements is arranged along the circumference of the sleeve-shaped circumferential wall between two press-fit pins.
  • press-in pins In principle, a large number of press-in pins is preferred to reduce the transition resistance between the outer conductor assembly and the electrical assembly, which is why it can be provided to use more press-in pins than spring-loaded contact elements. In general, however, any number of press-fit pins and any number of spring-loaded contact elements can be provided. The ratio between the number of press-fit pins and the number of spring-loaded contact elements can be arbitrary.
  • two to ten or more spring-loaded contact elements are provided, more preferably four to eight spring-loaded contact elements, in particular exactly six spring-loaded contact elements.
