Definitions

  • the present invention relates to an inner conductor spring-loaded contact element and an assembly containing this inner conductor spring-loaded contact element.
  • So-called board-to-board connectors have established themselves as fast data transmission interfaces for high-frequency signals between two high-frequency components, for example two printed circuit boards each with high-frequency electronics.
  • the task of these board-to-board connectors is to create an electrical connection for high-frequency signals between the two high-frequency components with an adjusted characteristic impedance.
  • the outer conductor contacts on the two high-frequency components are firmly connected to one another via an electrically conductive intermediate component that serves as an outer conductor.
  • This electrically conductive component can be, for example, an electrically conductive sleeve or an electrically conductive plate with a bore.
  • An inner conductor is arranged coaxially between the two high-frequency components in the bore of the sleeve or the plate for high-frequency transmission.
  • the inner conductor must compensate for an axial offset between the two high-frequency components due to a production-related inaccuracy in the planarity between the two high-frequency components.
  • two mutually contacting contact pins which are each connected to a printed circuit board and are arranged such that they can move relative to one another.
  • the two contact pins are biased by an elastic element which is clamped between transverse surfaces of the two contact pins.
  • a variable distance between two printed circuit boards is realized by a block of inner conductor, insulator and outer conductor, which is made of a conductive and a non-conductive elastomer, respectively.
  • the US 5,427,535A discloses the use of an elastically shaped contact element, which is encapsulated by an elastic insulating compound, to compensate for a variable distance between two printed circuit boards in the case of direct current contacting.
  • the EP 2 680 371 A1 and the EP 2 680 372 A1 each disclose a board-to-board connector that can compensate for an axial and/or rotational offset between two printed circuit boards.
  • the US 2004/0029433 A1 finally discloses an adapter between two coaxial connectors, which has an elasticity transverse to the longitudinal axis.
  • the inner conductor is implemented as a so-called SLC contact element (spring loaded contact).
  • SLC contact element spring loaded contact
  • an SLC contact element has a contact pin which is resiliently mounted in a socket-shaped housing. While the socket-shaped housing is typically fixed to one high-frequency component, the contact pin contacts the other high-frequency component with its contact tip. Due to the resilience of the contact pin in the socket-shaped housing, sufficient contact pressure and thus reliable electrical contact between the contact tip of the contact pin and an associated contact surface on the other high-frequency component can be achieved within a specific range for the distance between the two high-frequency components.
  • board-to-board connectors of this type also disadvantageously have too great a geometric extent in order to be able to meet future requirements for the spacing between a plurality of high-frequency contact elements in SLC technology positioned in a grid or in a row.
  • the present invention is based on the object of specifying an inner conductor contact and insulation between the outer conductor and inner conductor contact for high-frequency transmission between two high-frequency components and given fixed outer conductor contacting between the two high-frequency components Size and the number of its individual parts is minimized.

Due to its elasticity and its fixation on the at least one inner conductor, the elastic element can, in the compressed case - if the at least one inner conductor, which is variable in its axial extension, is also compressed when it comes into contact with the first and the second component - on the at least one inner conductor one Transmitted spring force with which the at least one inner conductor exerts a sufficient contact pressure on the first and second component.

  • the elastic element has a reduced rigidity in a central region between two end regions which are each adjacent to an axial end of the elastic element.
  • This reduced rigidity of the elastic element in its central area has the advantageous effect that the greatest elastic deformation of the elastic element occurs primarily in this central area and not in the two end areas.
  • the reduced rigidity in the central area of the elastic element is preferably realized by a reduced outer diameter and by a plurality of slots running in the longitudinal direction, which are located between the outer and inner surface of the hollow elastic element. Due to these slots running in the direction of the longitudinal axis, the reduced outer diameter of the central area increases when a compressive force acts in the direction of the longitudinal axis, while the axial longitudinal extent of the central area of the elastic element is advantageously shortened.

  • the individual recesses are preferably arranged at points in the central area in which a change in the elastic element in the radial direction occurs particularly strongly during contraction.
  • the effective permittivity is reduced in a section of the high-frequency transmission path in which the middle area of the elastic element is located. This increases the characteristic impedance in this section of the high-frequency transmission path.
  • the outer diameter of the at least one inner conductor in the section of the high-frequency transmission path in which the central area of the elastic element is located is opposite to the sections of the high-frequency transmission path in each of which the end regions of the elastic element are located, increased.
