Definitions

  • the invention relates to an electrical connector for printed circuit boards according to the preamble of claim 1 and a connector arrangement with an electrical connector according to the invention and an associated mating connector.
  • the invention also relates to a use of the connector arrangement for the electrical connection of two printed circuit boards.
  • B2B board-to-board
  • a disadvantage of such B2B connectors is their three-part design.
  • One possibility to achieve a simplification of the structure that is derived from the EP 2 780 985 B1 consists in providing a coaxial connection element whose outer conductor has a first conductor with a tubular jacket, the ends of which are intended for contact with the two boards and which has openings for tolerance compensation with regard to the distance between the boards, and also the outer conductor a tubular second conductor in electrical contact with the first conductor having a portion of the first conductor and is in axially movable contact with a portion of the first conductor.
  • a lateral offset of the printed circuit boards to be connected to one another can only be compensated for with difficulty.
  • the invention is based on the object of specifying an improved connector of the type mentioned at the outset, with which a B2B plug connection can be established. Another object is to specify a connector arrangement with this electrical connector with which a B2B connection can be implemented.
  • the tolerance compensation which compensates for the lateral axial offset is integrated into the electrical connector by means of a flexible bending section of the sleeve.
  • the compensating section can be pivoted with respect to the holding section, which is preferably connected to a printed circuit board, from the direction of the longitudinal axis of the sleeve of the plug connector.
  • a circumferential line of a sleeve in the description of the electrical connector and / or the sleeve in a cylindrical coordinate system in which the axis defining the axial direction through the plug-in direction of the Electrical connector is specified is a line, the points of which all have the same coordinate on this axis, so that the circumferential line lies in a plane that is perpendicular to the plug direction.
  • the structure of the outer conductor with a sleeve and at least one inner sleeve, which is arranged inside the sleeve and extends in the axial direction over a partial area of the sleeve, can, in particular when used for applications in the field of RF technology, essentially lead to a Contribute to improving the signal transmission properties. It goes without saying that the inner sleeve must be in electrical contact with the sleeve, at least in sections, in order to be part of the outer conductor.
  • the invention is when there is an inner sleeve which extends over the bending section.
  • an inner sleeve which extends over the bending section.
  • the introduction of slots in an outer conductor designed as a sleeve, as is done in the bending section, can lead to a noticeable deterioration in the signal quality.
  • This effect can be effectively counteracted by an inner sleeve which extends over the bending section and thus covers this area.
  • This embodiment is advantageously developed in that the inner sleeve springs back radially in the bending section.
  • empty volumes must remain between the first and the second partial dielectric body, which have undesirable effects in terms of HF technology. As the inner sleeve springs back radially in this area, these empty volumes can be noticeably reduced.
  • the inner sleeve is mechanically firmly and electrically conductively connected to the holding section and electrically conductively contacted with the connecting section in such a way that the contact point or the contact surface between the inner sleeve and the holding section can be displaced on the inner surface of the connecting section. In this way, it can contribute to the fact that the quality of the electrical contact hardly changes due to mechanical loading of the contact surface when the compensating section is deformed.
  • the inner sleeve is supported on the first partial dielectric body arranged in the holding section and / or is connected to the first partial dielectric body arranged in the holding section, migration of the inner sleeve in the connector can in particular be prevented.
  • the inner sleeve is radially spaced from the second partial dielectric body arranged in the connecting section. This measure can help to prevent undesired deformation of the inner sleeve in the axial direction, as can occur in particular with an axial load on the connecting section, and that instead, when such a load occurs, the contact surface between the connecting section of the sleeve, more precisely its inner surface, and the contact area of the inner sleeve to the connecting portion of the sleeve on the inner surface of the sleeve.
  • the second partial dielectric body arranged in the connecting section is designed in a stepped manner, so that its diameter extends in the direction of the first partial dielectric body reduced towards.
  • this distance should be kept as small as possible.
  • the inner sleeve is mechanically preloaded in such a way that a contact pressure acts on the inner surface of the connecting section at the contact point or on the contact surface between the inner sleeve and the holding section in order to ensure good and intimate electrical contact between the inner sleeve in the compensating section even if the compensating section is deformed Ensure area.
  • a second inner sleeve is present which extends into a contact zone of the connecting section of the sleeve in which the electrical connection to the associated mating connector is established.
  • this enables the contact zone of the connecting section to widen in a funnel-shaped manner in the direction of the plug-in end of the sleeve, which can be desirable in order to ensure good electrical contact with the outer conductor of a mating connector that overlaps the outer conductor of the sleeve as a socket, and still a negative one Avoid influencing the HF signal as much as possible.
  • inner sleeves which are elastically deformable, that is to say have high elasticity, as is the case, for example, with spring materials.
  • At least two slots are arranged one behind the other in the circumferential direction of the sleeve, the bending section preferably being formed with at least two slots in the axial direction, which are arranged offset from one another.
  • the connecting web is designed with an axial length corresponding to the width of the slot.
  • a slot has an axial width so that the opposite end faces of the holding section and the compensating section are spaced apart and therefore the connecting web also has an axial length corresponding to the axial width of the slot, which ensures the required flexural elasticity in the area of the bending section.
  • a further advantageous development of the invention provides that the inner conductor has a cross-sectional taper in the transition region of the first dielectric sub-body and the second dielectric sub-body. This also gives the inner conductor the necessary flexural elasticity in the area of the flexible section of the sleeve.
  • a further improvement in the flexural elasticity in the area of the bending section is ensured by the fact that the diameter of the inner conductor in the area of the second dielectric part body has a smaller diameter compared to Diameter of the inner bore of the second dielectric part body is formed.
  • one of the adjacent end faces of the first and second dielectric part body has a blind hole and the other end has a contour adapted to this, but which has a smaller diameter than the blind hole by an axial offset and / or to enable tilting of the second dielectric body relative to the first dielectric body.
  • a further improvement in the bending elasticity in the area of the bending section is achieved according to a further development in that the connecting web has an inwardly pointing bead running in the circumferential direction.
  • the second dielectric part body is formed with a groove running in the axial direction, which runs congruently with the connecting web for receiving its bead and is therefore designed with a depth corresponding at least to the height of the bead on the inner wall of the sleeve.
  • the bead is preferably designed as a triangular bead.
  • the holding section of the sleeve is on an end face opposite the bending section with a connecting flange for mechanical and electrical connection to a printed circuit board educated.
  • the sleeve of the connector according to the invention can thus be used as an SMD component.
  • the compensating section of the sleeve is designed with an end face opposite the bending section with a contact zone for making electrical contact with a mating connector.
  • the contact zone of the compensating section preferably has a circumferential bead, the bead base of which is designed to make contact with an outer conductor of a mating connector.
  • the second partial dielectric body is preferably designed to be shortened by the axial length of the contact zone, that is to say arranged outside the contact zone, so that the sleeve can accommodate the contact zone of a mating connector as a socket in the area of the contact zone.
  • Such an electrical connector arrangement is suitable for use as a B2B connector for connecting two parallel printed circuit boards, in which a lateral axial offset between the electrical connector and the associated mating connector is compensated for by means of the bending section of the connector according to the invention.
  • the Figures 1 and 2 show an electrical connector 1.1, which together with an associated mating connector 1.2 according to FIG Figure 3 a connector arrangement 1 as a B2B connector electrically connects two printed circuit boards, not shown, to one another as shown in FIG.

  • the electrical connector 1.1 via a connecting flange 2.10 mechanically and electrically with the one printed circuit board and the mating connector 1.2 via a Connection flange 1.23 mechanically and electrically connected to the other circuit board.
  • This connector arrangement 1 has the property that in the event of a lateral offset or angular offset of the connectors 1.1 and 1.2 mechanically connected to the circuit boards with regard to their axes of symmetry, tolerance compensation for this offset is made possible by means of the electrical connector 1.1.
  • the connector assembly 1 according to Figure 4 exposed to an angular offset, as can occur, for example, when the circuit boards are not completely aligned parallel to one another, the two connectors 1.1 and 1.2 tilt towards one another. This tilting is compensated for by means of a bending section 2.3 or a bending zone of the electrical connector 2.1 of the connector arrangement 1.
  • This compensation or tolerance function of the electrical connector 1.1 which also works with a parallel offset of the circuit boards and thus the axes of symmetry of the connectors 1.1 and 1.2 arranged on them, is explained below.
  • the electrical connector 1.1 comprises an outer conductor 2.0 consisting of a sleeve 2a and two inner sleeves 2b, 2c arranged within the sleeve 2a, each extending in the axial direction over a portion of the sleeve 2a, an inner conductor pin 3 as an inner conductor 3.0 and one of the remaining ones Space between the inner conductor 3.0 and the outer conductor 2.0 largely filling the dielectric 4.0, which is constructed as a substantially cylindrical dielectric body 4 in two parts from a first dielectric sub-body 4.1 and a second dielectric sub-body 4.2.

  • an inner sleeve 2c is arranged in the plug-side end area as a further component of the outer conductor 2.0, which is held between the plug-in end area 4.24 of the second dielectric part body 4.2 and the inside of a section of the compensating section 2.2 of the sleeve 2a and is essentially the same up to its plug-side end extends radial distance from the central axis of the electrical connector 1.1.
