DETAILED WRITTEN DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0091] This disclosure of the invention is submitted in furtherance of the Constitutional purposes of the US Patent Laws “to promote the progress of Science and the useful arts” (Article 1, Section 8).

[0092] FIGS. 1A to 1C show a first variant of an electrical plug connection 1 comprising an electrical plug connector 2 and an associated electrical mating plug connector 3. The electrical plug connection 1 shown in FIGS. 1A to 1C relates to a plug connector 2 formed as an adapter (=bullet) and an electrical mating plug connector 3 formed as a housing plug connector of a filter module, as used in a printed circuit board-to-filter connection (board-to-filter connection) or alternatively in a printed circuit board-to-printed circuit board connection (board-to-board connection). The electrical plug connector 2 is designed in particular to compensate for a variable distance between the printed circuit board and the filter module or between two printed circuit boards, i.e. an axial offset.

[0093] The electrical plug connector 2 has an inner conductor contact element 4, which is coaxially sheathed by an outer conductor contact element 5 at least in a middle axial longitudinal portion. For mechanical spacing and electrical insulation of the inner conductor contact element 4 from the outer conductor contact element 5, an insulator element 6 is arranged between the inner conductor contact element 4 and the outer conductor contact element 5 at least in the middle axial longitudinal portion.

[0094] An inner-conductor-side contact region 7 of the inner conductor contact element 4 and an outer-conductor-side contact region 8 of the outer conductor contact element 5 are provided and are each formed by way of example at the plug-in-side end 9 of the electrical plug connector 2. The contact regions 7, 8 are each formed elastically, i.e. as a spring contact sleeve with a plurality of spring lugs 10. The inner-conductor-side contacting between the spring lugs 10 of the inner-conductor-side contact region 7 of the electrical plug connector 2 and an inner conductor mating contact element 11 of the electrical mating plug connector 3 takes place via individual contact points on the spring lugs 10 lying on a circular line in an inner-conductor-side contact plane 13. Equivalently, the outer-conductor-side contacting between the spring lugs 10 of the outer-conductor-side contact region 8 of the electrical plug connector 2 and an outer conductor mating contact element 12 of the mating plug connector 3 takes place via individual contact points on the spring lugs 10 lying on a circular line in an outer-conductor-side contact plane 14.

[0095] It should be noted at this juncture that the variants of the plug connection 1, or rather of the electrical plug connector 2, shown in the exemplary embodiments, in which the contact planes 13, 14 are each located at the distal end of the inner conductor contact element 4 and the outer conductor contact element 4 respectively, are not to be understood in a limiting manner. Within the scope of the claimed invention, it may also be provided that the contact planes 13, 14 are axially offset with respect to the relevant distal end. For example, spring lugs 10 with conically curved contact regions 7, 8 of which the contact points are spaced from the distal end are frequently used.

[0096] The axial distance between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14 preferably corresponds to a quarter of the wavelength (i.e. λ/4) of the electrical signal to be transmitted via the plug connection 1, in particular the high-frequency signal to be transmitted. With this geometrical configuration of the plug connector, optimum suppression of a reflection of an electrical signal at the inner-conductor-side contact plane 13 and at the outer-conductor-side contact plane 14 is possible, provided that the amplitudes of the electrical signals reflected at the inner-conductor-side contact plane 13 and at the outer-conductor-side contact plane 14 are each equal. The latter condition is typically given. In the variant of the plug connection 1 shown in FIGS. 1A to 1C, the inner-conductor-side contact plane 13 projects axially beyond the outer-conductor-side contact plane 14.

[0097] In an axial portion of the inner conductor contact element 4 adjacent to the spring sleeve, a plurality of slot-shaped recesses 15, preferably four slot-shaped recesses 15, are formed in the inner conductor contact element 4, and, with regard to their longitudinal extent, each extend from the outer lateral surface of the inner conductor contact element 4 in mutually orthogonal directions to the longitudinal axis of the inner conductor contact element 4. With an elasticity in the inner conductor contact element 4 realized by the slot-shaped recesses 15, it is possible to compensate for an asymmetry between the inner conductor contact element 4 and the outer conductor contact element 5.

[0098] On the other hand, the slot-shaped recesses 15 in the inner conductor contact element 4 and the spring lugs 10 of the outer conductor contact element 5 allow inner-conductor-side and outer-conductor-side elasticity to compensate for a radial offset between a printed circuit board and a filter module or between two printed circuit boards via the adapter arranged between them and the printed circuit board plug connector connected to the printed circuit board or the housing plug connector connected to the filter module. In order to thus compensate for an existing asymmetry or an existing radial offset via the elasticity of the slot-shaped recesses 15, a clearance 16, (i.e. an area freed from the insulator element 6), is formed between the inner conductor contact element 4 and the outer conductor contact element 5 in the axial region of the slot-shaped recesses 15. With regard to impedance matching, the inner conductor contact element 4 has a diameter in the axial portion of the clearance 16 which is increased compared to the diameter in the axial portion with the insulator element 6.

[0099] The electrical mating plug connector 3 has an inner conductor mating contact element 11 in the form of a pin, an outer conductor mating contact element 12 in the form of a socket, and an insulator element 17 arranged therebetween. In the case of a filter module, the electrical mating plug connector 3 can also be formed as a housing plug connector in a bushing of the housing belonging to the filter module. If the plug connection is used in a board-to-board connection or in a board-to-filter connection, the inner-conductor-side mating contact region 18 of the inner conductor mating contact element 12 and the outer-conductor-side mating contact region 19 of the outer conductor mating contact element 11 each have a specific axial extent in order to compensate for an axial offset between a printed circuit board and a further printed circuit board or a filter module. The axial extent of the inner-conductor-side contact region 18 and of the outer-conductor-side contact region 19 corresponds in each case at least to the permissible maximum axial offset.

[0100] FIG. 1B shows a plug-in connection 1 in an exemplary first plug-in position, in which the inner-conductor-side contact plane 13 is located in a middle region of the inner-conductor-side mating contact region 18 and the outer-conductor-side contact plane 14 is also located in a middle region of the outer-conductor-side mating contact region 19.

[0101] In the first plug-in position, the electrical plug connector 2 is only partially inserted in the electrical mating plug connector 3 in the axial direction. FIG. 1C shows a second plug-in position of the plug connection 1, in which the inner-conductor-side contact plane 13 is located in an end position of the inner-conductor-side mating contact region 18 facing away from the plug-in side and the outer-conductor-side contact plane 14 is also located in an end position of the outer-conductor-side mating contact region 19 facing away from the plug-in side. The electrical plug connector 2 is inserted in the electrical mating plug connector 3 in the second plug-in position in the axial direction to the maximum extent possible.

[0102] To ensure that a reflection of the electrical signal is minimized, preferably completely compensated, also in the second plug-in position of the plug connection 1, the axial distance between the outgoing-side end 20 of the inner-conductor-side mating contact region 18 and the outgoing-side end 21 of the outer-conductor-side mating contact region 19 preferably corresponds to a quarter of a wavelength λ/4 of the electrical signal to be transmitted via the plug connection 1.

[0103] It can also be seen from FIG. 1A that the axial distance L between the plug-side end 22 and the plug-side end 23 of the inner-conductor-side mating contact region 18 is preferably greater than the axial distance between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14 amounting to preferably a quarter of a wavelength λ/4 of the electrical signal to be transmitted via the plug connection 1. This guarantees that, in a plugging process, the outer-conductor-side contacting precedes the inner-conductor-side contacting between the plug connector 2 and the mating plug connector 3.

[0104] The axial extent L.sub.A of the outer-conductor-side mating contact region 19 between the plug-side end 22 and the outgoing-side end 21 of the outer-conductor-side mating contact region 19 and the axial extent L.sub.I of the inner-conductor-side mating contact region 18 between the plug-side end 23 and the outgoing-side end 20 of the inner-conductor-side mating contact region 18 correspond at least to the maximally permissible axial offset, as also shown in FIG. 1A.

[0105] To allow the inner conductor contact element 4 of the electrical plug connector 2 to be joined as far as the outgoing-side end 20 of the inner-conductor-side mating contact region 18 of the inner conductor mating contact element 17 of the electrical mating plug connector 3, the insulator element 17 of the mating plug connector has a sleeve-shaped recess 24 on its inner lateral surface over the axial extent of the inner-conductor-side mating contact region 18. The sleeve-shaped recess 24 is preferably formed in such a way that, when the plug connection 1 is in the fully plugged state, the insulator element 17 completely fills the axial region between the outer conductor mating contact element 12 and the inner conductor contact element 4.

[0106] The sleeve-shaped recess 24 of the insulator element 17 forms a step at the outgoing-side end 20 of the inner-conductor-side mating contact region 18, said step forming an axial stop for the inner conductor contact element 4 of the electrical plug connector 2 in the fully plugged state according to FIG. 1C. Equivalently, the outer conductor mating contact element 12 has a step at the outgoing-side end of the outer-conductor-side mating contact region 19, said step forming an axial stop for the outer conductor contact element 5 of the electrical plug connector 2 in the fully plugged state.

[0107] The electrical plug connector 2 has a first axial longitudinal portion I extending between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14. This is followed by a second axial longitudinal portion II of the electrical plug connector 2, as can be seen in FIGS. 1A to 1C. Similarly, the electrical mating plug connector 3 has a third axial longitudinal portion III and a fourth axial longitudinal portion IV. It is envisaged that the wave impedance in the second axial longitudinal portion II of the electrical plug connector 2 and in the third axial longitudinal portion III of the electrical mating plug connector 3 is identical. In a fifth axial longitudinal portion V of the plug connector 1, which is located between the second and third axial longitudinal portions when the plug connector 1 is in the plugged state, there is a wave impedance that differs therefrom, in particular a higher wave impedance than in the second and third axial longitudinal portions II and III.

[0108] FIGS. 2A to 2C each show a preferred extension of the first variant of a plug connection 1 according to the invention already disclosed in FIGS. 1A to 1C. For transport protection of the elastically formed inner conductor contact element 4, which has an axial protrusion with respect to the outer conductor contact element 5, the axial portion of the inner conductor contact element 4 between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14 is surrounded by an additional insulator element 25. The additional insulator element 25 of the electrical plug connector 2 preferably has an outer diameter that corresponds to the outer diameter of the insulator element 17 arranged in the electrical mating plug connector 3. The axial extent of the insulator element 17 arranged in the electrical mating plug connector 3 is reduced by the axial extent of the additional insulator element 25. Both geometrical conditions allow, on the one hand, the electrical plug connector 2 to be inserted into the electrical mating plug connector 3 and, on the other hand, the space between the outer conductor mating contact element 12 and the inner conductor contact element 4 to be completely filled over the first axial longitudinal portion I of the electrical plug connector 2 when the electrical plug connector 2 is fully plugged into the electrical mating plug connector 3.

[0109] FIGS. 3A to 3C show a second variant of a plug connection 1 in which the outer conductor contact element 5 projects axially beyond the inner conductor contact element 4. Consequently, the inner conductor mating contact element 11 projects beyond the outer conductor mating contact element 12 of the electrical mating plug connector 3.

[0110] In order to compensate for a radial offset in a board-to-board connection or in a board-to-filter connection in the second variant of a plug connection 1, an elasticity of the outer conductor contact element 5 belonging to the electrical plug connector 2, i.e. the outer-conductor-side spring contact sleeve, and an elasticity of the inner conductor mating contact element 11 belonging to the electrical mating plug connector 3 are used.

[0111] This is due to the fact that in the second variant the inner conductor mating contact element 11 of the electrical mating plug connector 3 forms the protruding and thus longer contact element, while in the first variant the inner conductor contact element 4 of the electrical plug connector 2 forms the protruding and thus longer contact element.

[0112] For this purpose, four slot-shaped recesses 15 are preferably formed in the pin-shaped inner conductor mating contact element 11, the longitudinal extent of each of which extends from the outer lateral surface of the inner conductor mating contact element 11 in mutually orthogonal directions in the direction of the longitudinal axis of the inner conductor mating contact element 11. In order to allow a radial elasticity of the inner conductor mating contact element 11, equivalently arranged and shaped axially adjacent slot-shaped recesses 27 are formed in the insulator element 17 of the electrical mating plug connector 3. Lastly, slot-shaped recesses 15 in the inner conductor mating contact element 11 and slot-shaped recesses 27 in the insulator element 17 are each formed in an axial portion in which a clearance 28 is provided in the outer conductor mating contact element 12 of the mating plug connector.

[0113] FIGS. 4A and 4B each show a third variant of a plug connection 1 which has no possibility for axial offset compensation. The axial spacing between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14, preferably amounting to a quarter of a wavelength λ/4 of the electrical signal to be transmitted, is realized by an additional axial fixing between the electrical plug connector 2 and the electrical mating plug connector 3.

[0114] In the plug connection of FIGS. 4A and 4B, axial fixing is achieved, for example, via an axial stop 29 formed in the outer conductor contact element 5, against which stop the outer conductor mating contact element 12 axially abuts in the plugged state, and a union nut 30. The union nut 30 is rotationally movably connected to the electrical plug connector 2 and can be screwed via an internal thread to an external thread formed on the outer conductor contact element 12. However, other technical solutions for an axial fixing between the electrical plug connector 2 and the electrical mating plug connector 3 are also conceivable, such as a latching between the plug connector housing and the mating plug connector housing.

[0115] In contrast to the first and second variants of the plug connection 1, the electrical plug connector 2 in the third variant has an inner conductor contact element 4 in the form of a pin with an inner-conductor-side contact region 7, and an outer conductor contact element 5 formed as a spring contact sleeve with an outer-conductor-side contact region 8, which forms an outer-conductor-side contact plane 14. Correspondingly, the electrical mating plug connector 3 has an inner conductor mating contact element 11 in the form of a spring contact sleeve with an inner-conductor-side mating contact region 18, which forms an inner-conductor-side contact plane 13, and an outer conductor mating contact element 12 in the form of a socket with an outer-conductor-side mating contact region 19. In the plugged state, the plug connection 1 is dimensioned such that the axial distance between the inner-conductor-side contact plane 13 and the outer-conductor-side contact plane 14 preferably corresponds to a quarter of a wavelength λ/4 of the electrical signal.

[0116] In the third variant of the plug connection, the wave impedance in the second axial longitudinal portion II of the electrical plug connector 2 corresponds to the wave impedance in the third axial longitudinal portion III of the electrical mating plug connector 3. The wave impedance in a fifth longitudinal portion V of the plug-in connection 1, which is located between the second axial longitudinal portion II and third axial longitudinal portion III in the plugged state of the plug-in connection 1, is different from the wave impedance in the second and in the third axial longitudinal portions II and III, in particular smaller than in the second and third axial longitudinal portions II and III.

[0117] Although the present invention has been fully described above with reference to preferred exemplary embodiments, it is not limited thereto, but can be modified in a variety of ways.
