Definitions

  • the invention relates to an electrical connector having an insulating part and at least one pair of inner conductor contact elements for differential signal transmission, the pair of inner conductor contact elements comprising a first inner conductor contact element and a second inner conductor contact element, which extend from a first end of the insulating part to a second end of the insulating part through the insulating part , according to the preamble of claim 1.
  • 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, a coupling or an adapter.
  • 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 To transmit data at high data rates, an electrical connector often has a differential pair of inner conductor contact elements.
  • the quality of the signal transmission depends essentially on the transition resistance between the inner conductor contact elements and an electrical assembly connected to the electrical connector and the adaptation of the characteristic impedance in the electrical connector.
  • the suitability of the connector for mass production should also be taken into account and the effort required to mount the connector on the electrical assembly should be kept low.
  • the electrical and mechanical contact between the inner conductor contact elements of the electrical plug connector and the electrical assembly is in practice often done via a so-called interference fit or "press fit".
  • press-in pins are pressed into associated metallized recesses in the electrical assembly under a specific press-in pressure. In this way, a cold welding is caused and a material connection is formed between the press-fit pins and the recesses.
  • press-in pressure that is as symmetrical as possible should be exerted on the respective press-fit pin.
  • the press-in pins in practice each have two opposing support shoulders, via which the press-in force is correspondingly uniformly transmitted.

  • the “overpressing” that occurs during the press-in process can be absorbed by deformation in the recess or in the press-fit pin.
  • the force that has built up preferably results in 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.

  • the inner conductor contact elements each have exactly one support shoulder via which a press-in force required to press the press-fit pin into the metallized recess can be introduced (indirectly or directly, preferably based on a suitable assembly tool).

  • the number or the density of contact elements can advantageously be increased without risking assembly-related damage or breakage of the electrical assembly, for example an electrical circuit board. 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 and the contact resistance reduced in order to provide an electrical connector for the transmission of signals with even higher frequencies.
