Definitions

  • the present invention relates to an electrical plug connector having the features of patent claim 1.
  • the present invention also relates to an electrical mating connector having the features of patent claim 8.
  • the present invention relates to an electrical plug connector having the features of patent claim 15.
  • Electrical connectors are used in particular for the transmission of data signals and supply voltages to corresponding mating connectors. If a high volume of data has to be transmitted in a data signal, the data to be transmitted is modulated onto a high-frequency carrier signal. Electrical high-frequency plug connectors have become established for the transmission of such a high-frequency signal.
  • An electrical high-frequency plug-in connection is characterized above all by good electrical transmission properties, the simplest possible plugging and unplugging of the connection, good shielding of electromagnetic fields and a connection that is as low-reflection as possible between two high-frequency lines, each with an identical characteristic impedance.
  • the electrical contact between the inner and the outer conductor contact elements of the electrical connector and the electrical mating connector takes place in the most commonly used electrical connector, namely the polarized electrical connector, via a pin-socket contact or a socket-socket contact.
  • the pin-socket or socket-socket contact is functionally associated with a change in the diameter between the two contact partners and thus with a point of discontinuity in the transmission link on the inner and outer conductor side.
  • a radial offset between the electrical connector and the electrical mating connector can lead to a point of discontinuity in the transmission path, at least on the inner-conductor side.
  • Each inner conductor-side and/or outer conductor-side discontinuity within the electrical plug-in connection disadvantageously causes a reflection of the high-frequency signal to be transmitted via the electrical plug-in connection and thus disadvantageously impairs the high-frequency transmission properties of the electrical high-frequency plug-in connector.
  • the present invention is based on the object of specifying an electrical high-frequency plug-in connection that is optimized with regard to its high-frequency transmission behavior.
  • a surface vector or normal vector of the named contact planes is preferably oriented in each case parallel to the insertion direction.
  • the finding/idea on which the present invention is based is to position the contact plane on the inner conductor side and the contact plane on the outer conductor side between the connector and the mating connector in such an axial manner relative to one another that the high-frequency signal reflected in the contact plane on the inner conductor side and the high-frequency signal reflected in the contact plane on the outer conductor side each have a phase offset each other that a superimposition of the two reflected and mutually phase-shifted high-frequency signals ideally leads to mutual complete compensation.
  • a contact plane is understood here and below to mean a plane which is preferably oriented orthogonally to the longitudinal axis of the electrical plug connection.
  • the contact plane is spanned by the individual common contact points of the respective contact area, in which the inner conductor contact element and the associated inner conductor mating contact element or the outer conductor contact element and the associated outer conductor mating contact element make contact when the electrical plug connection is plugged in.
  • these common contact points preferably lie on a circular line which is preferably aligned coaxially to the longitudinal axis of the electrical plug connection.
  • contact is also made on the inner or outer conductor side via a number of contact points in each case.
  • these common contact points preferably lie within an annular area (and thus also on at least one circular line) and in the case of an inner conductor contacting, they lie within a circular area or within an annular area.
  • the ring-shaped area or the circular area is preferably aligned orthogonally to the longitudinal axis of the electrical plug connection.
  • the contact level contains at least three, but preferably the sum of all contact points between the two contact partners in the plugged-in state of the electrical plug connection
  • the contact area of a contact element in the case of radial contact is the outer lateral surface of a pin-shaped contact element, the outer or inner lateral surface of a socket-shaped contact element or the contact points of all spring tabs of a contact element designed as a spring contact sleeve and, in the case of end contacting, the end face of a contact element.
  • the contact area on the inner conductor side/outer conductor side and/or the counter-contact area on the inner conductor side/outer conductor side can optionally have an axial extension or an extension in the insertion direction exhibit.
  • all contact areas of the plug connector have no axial extension and all mating contact areas of the mating connector have an axial extension—or vice versa.
  • a mixed variant according to which, for example, the contact area on the inner conductor side has no axial extension and the counter-contact area on the inner conductor has an axial extension, and the contact area on the outer conductor side has an axial extension and the counter-contact area on the outer conductor side has no axial extension, can be provided (or vice versa). If at least one of the contact partners has a contact area or mating contact area with an axial extent, tolerances in the direction of insertion can be compensated particularly well.
  • a plugged-in state of the electrical connector and the electrical mating connector is understood below to mean a state in which a contact area of the inner conductor contact element of the electrical connector is a mating contact area of the inner conductor mating contact element of the electrical mating connector and a contact area of the outer conductor contact element of the electrical connector is a mating contact area of the outer conductor mating contact element of the electrical mating connector contacted.
  • the electrical connector and the mating electrical connector are each preferably a coaxial connector, e.g. H. a connector with an outer conductor contact element, the longitudinal axis of which is positioned and oriented identically to the longitudinal axis of the single inner conductor contact element (coaxial).
  • the invention also covers an electrical plug connection with more than one inner conductor contact element, for example two inner conductor contact elements, three inner conductor contact elements, four inner conductor contact elements or more than four inner conductor contact elements.
  • the individual inner conductor contact elements are preferably each formed identically and are each oriented identically within the outer conductor contact element.
  • the inner conductor contact element and the outer conductor contact element of the electrical connector are each socket-shaped and the inner conductor mating contact element of the electrical Mating connector corresponding pin-shaped and the outer conductor mating contact element of the electrical mating connector corresponding socket-shaped.
  • the inner conductor contact element of the electrical plug connector is pin-shaped and the inner conductor mating contact element of the electrical mating connector is correspondingly socket-shaped.
  • the electrical connector or the mating electrical connector can be a cable connector, a printed circuit board connector, a housing connector or an adapter between two of the connector types mentioned.
  • it can be an adapter that is plugged into a so-called board-to-board connection between two circuit board connectors, or an adapter that is in a so-called board-to-filter connection between a circuit board connector and a housing connector of a filter module is inserted.
  • the idea according to the invention can be used in an electrical connector and in an electrical mating connector, which are each designed as a straight connector or as an angled connector.
  • the inner and outer conductor contact elements and the inner conductor and outer conductor mating contact elements can each be manufactured using machining technology (turning technology), stamping and bending technology, deep-drawing technology, embossing technology or other production technologies.
  • the outer conductor contact element preferably encloses each inner conductor contact element over the entire axial longitudinal extent of the inner conductor contact element.
  • the plug-side end of the outer conductor contact element can protrude beyond the plug-side end of each inner conductor contact element in the axial direction, so that during a plugging process the outer conductor contact element contacts the outer conductor mating contact element before the inner conductor mating contact element makes contact with the inner conductor contact element.
  • the electrical connector in the plugging process is typically first on the associated connector housing, then on the associated outer conductor contact elements and finally on the associated inner conductor contact elements to the mating electrical connector aligned.
  • Such a geometric arrangement between the outer and the inner conductor contact element also protects the inner conductor contact element from the more robust outer conductor contact element during transport of the electrical plug connector.
  • the distal end of the inner conductor contact element can protrude beyond the distal end of the outer conductor contact element in the axial direction. This is particularly conceivable with adapters for a board-to-board connection or for a board-to-filter connection, also known as a bullet. Damage to the inner conductor contact element is prevented in this case, since such connections are generally not plugged in by hand, but in automated assembly lines.
  • the axial distance between the contact plane on the inner conductor side and the contact plane on the outer conductor side in the electrical connectors or in the electrical mating connector corresponds approximately (especially within tolerances) or exactly to a quarter of the wavelength of the electrical signal that is transmitted via the plug connection .
  • the electrical signal reflected at the contact plane on the inner conductor side due to the point of discontinuity there and the electrical signal reflected at the contact plane on the outer conductor side due to the point of discontinuity there have a phase shift of half the wavelength of the electrical signal.
  • This compensation condition relates to a transmission frequency of the electrical signal.
  • a data signal modulated onto a high-frequency carrier signal requires a certain bandwidth relative to the carrier frequency.
  • a narrow-band transmission signal is therefore preferably used for the transmission via the electrical plug connection according to the invention.
  • the axial spacing between the contact plane on the inner conductor side and the contact plane on the outer conductor side is preferably designed for the frequency that corresponds to the frequency of the spectral component of the narrow-band transmission signal with the highest amplitude. In this way, the spectral component of the narrow-band transmission signal with the highest amplitude can be completely compensated and is therefore not reflected.
  • the respective adjacent spectral components of the narrow-band transmission signal are at least partially compensated by the measure according to the invention and can be completely compensated by additional technical compensation measures.
  • the axial distance between the contact level on the inner conductor side and the contact level on the outer conductor side in the electrical connector or in the electrical mating connector can also be in a range between 0 .2 times and 0.3 times a wavelength of the electrical signal, preferably in the range between 0.22 times and 0.28 times the wavelength of the electrical signal, particularly preferably in the range between 0.24 and times and 0.26 times the wavelength of the electrical signal.
  • the inner conductor contact element and/or the outer conductor contact element is preferably designed as a radially contacting contact element. But it can also be provided a frontal contact.
  • the contact element or alternatively the mating contact element is designed as a spring contact sleeve with at least two spring tabs on the inner conductor side and the outer conductor side.
  • the spring contact sleeve causes sufficient contact pressure between the two contact partners.
  • contacting by means of a spring contact sleeve avoids multiple contacts that are axially spaced apart from the contact partner and thus undesired passive intermodulation.
  • the contact to the contact partner is made solely via contact points on the individual spring shackles, which lie on a circular line of the contact level.
  • an insulator element encloses the at least one inner conductor contact element between the inner conductor-side contact plane and the outer conductor-side contact plane.
  • the insulator element which is referred to below as an additional insulator element, is set up to fill a space between an outer conductor mating contact element of the mating connector and the at least one inner conductor contact element of the connector when the connector and the mating connector are in a plugged-in state.
  • the additional insulator element can serve as transport protection.
  • the additional isolator element enables mechanical stabilization of the connector in the mating connector and stronger centering, i. H. erecting or parallelizing the connector to the mating connector.
  • the connector is used as an adapter in a board-to-board connection or in a board-to-filter connection, there may be a misalignment between the two printed circuit boards or between the printed circuit board and the filter module position in a direction transverse to the longitudinal axis of the adapter.
  • a radial offset between the two circuit board connectors or between a circuit board connector and a housing connector of the filter module should be balanced by the adapter.
  • a further elasticity is formed in the inner conductor contact element, which bridges the radial offset that occurs between the two axial ends of the adapter.
  • the additional elasticity of the inner conductor contact element is preferably a slot-shaped recess in the inner conductor contact element.
  • the slot-shaped recess is a slot formed on the lateral surface of the inner conductor contact element, the longitudinal extension of which runs transversely to the longitudinal axis of the inner conductor contact element.
  • Four slot-shaped recesses are preferably formed, which each run in one of four mutually orthogonal directions, starting from the lateral surface of the inner conductor contact element. With recesses shaped and oriented in this way in the inner conductor contact element, a radial offset in all four radial directions in the adapter can thus be compensated for.
  • the slit-shaped recesses are preferably formed in an axial section of the inner conductor contact element, which directly adjoins the axial end of the inner conductor contact element, which is designed as a spring contact sleeve. In this axial section, no insulator element is arranged between the inner conductor contact element and the outer conductor contact element, so that a radial displacement between the axial end and the middle section of the inner conductor contact element is possible.
  • the slot-shaped recesses in the inner conductor contact element can also compensate for a lack of centricity between the inner conductor and the outer conductor contact element of the connector.
  • At least one slit-shaped recess can also be formed in the inner conductor mating contact element in order to compensate for a radial offset or a lack of centricity between the inner conductor and the outer conductor mating contact element of the mating connector.
  • slot-shaped recesses should preferably also be formed in the axial vicinity in the insulator element with regard to an elastic deformation possibility of the inner conductor mating contact element in the radial direction.
  • a free space is preferably formed axially adjacent to the insulator element to the slot-shaped recesses in the inner conductor contact element or in the insulator element, which allows the radial mobility of the inner conductor mating contact element with or without the insulator element.
  • An electrical plug-in connection equipped according to the invention for the transmission of a high-frequency signal ultimately has a minimized reflection behavior, preferably no reflection behavior, along its entire transmission path.
  • the course of the characteristic impedance or the impedance thus has minimized points of discontinuity, preferably no points of discontinuity, along the entire transmission path.
  • a first axial longitudinal section of the plug connector between the contact plane on the inner conductor side and the outer conductor side thus has a different characteristic impedance than a second axial longitudinal section of the plug connector, which adjoins the first axial longitudinal section.
  • a fourth axial longitudinal section of the mating connector between the outgoing end of the inner conductor-side mating contact area and the mating end of the outer conductor-side mating contact area has a different characteristic impedance than a third axial longitudinal section of the mating connector, which adjoins the fourth axial longitudinal section.
  • the course of the characteristic impedance is preferably constant within the first, second, third and fourth longitudinal sections.
  • the characteristic impedance in the second longitudinal section of the connector preferably corresponds to the characteristic impedance of the third longitudinal section of the mating connector and is adapted to the characteristic impedance of the other transmission components and is, for example, 50 ⁇ .
  • the contact areas on the outer and inner conductor side of at least one of the contact partners each have an axial distance corresponding to the distance interval expansion on.
  • the contact areas on the outer and inner conductor side of one contact partner can make electrical contact with different contact positions within the contact areas of the other contact partner, depending on the axial distance.
  • a variable axial offset i. H. a variable distance between a printed circuit board and another printed circuit board or alternatively a filter module.
  • the contact areas of the adapter formed in the outer and inner conductor contact elements each make contact with different contact positions within the mating contact area of the printed circuit board connector or the housing connector belonging to the filter module on the outer or inner conductor side.
  • the mating contact areas of the mating connector on the inner conductor and outer conductor side preferably have a sufficient axial extent.

  • a recess is preferably formed in the outer conductor mating contact element and in the insulator element of the mating connector, which extends along the mating contact area on the outer conductor side or along the mating contact area on the inner conductor side.
  • This recess in the outer conductor mating contact element and in the insulator element of the mating connector each form a step and thus a point of discontinuity in the course of the outer conductor mating contact element or in the insulator element of the mating connector.
  • the point of discontinuity is located at an outgoing end of the counter-contact area on the outer conductor side or at an outgoing end of the counter-contact area on the inner conductor side.
  • the procedure is analogous to the compensation of the signal reflected at the inner conductor and at the outer conductor side contact level of the connector.
  • An axial distance between an outgoing end of the inner conductor-side counter-contact area and an outgoing-side end of the outer conductor-side counter-contact area is to be set up in such a way that when the plug connector and the mating connector are plugged in, there is compensation for the reflected contact area at the outgoing-side end of the inner-conductor-side counter-contact area and at the outgoing-side end of the outer-conductor-side counter-contact area electrical signal can be achieved.

  • the inner conductor mating contact element of the mating connector can also be at least partially along the mating contact area on the inner conductor side, preferably along the entire mating contact area on the inner conductor side be encased in an insulator element.
