DETAILED WRITTEN DESCRIPTION OF THE PREFERRED EMBODIMENTS

(33) This disclosure of the invention is submitted in furtherance of the Constitutional purposes of the U.S. Patent laws “to promote the progress of science and useful arts (Article 1, Section 8).

(34) FIG. 1 shows a prefabricated electric cable 1 according to the prior art which is fitted with a plurality of plug-in connector components of an electrical plug-in connector. The cable 1 is fitted with an external conductor contact element 2, a dielectric 3 and an internal conductor contact element pair 4 (FIG. 3) for differential signal transmission. Said plug-in connector components 2, 3, 4 are part of a differential electrical plug-in connector, not illustrated in greater detail in FIGS. 1 to 3. FIG. 2 shows a longitudinal section view through the plug-in connector components 2, 3, 4, and FIG. 3 shows a cross section view through said components.

(35) The dielectric 3 extends along a longitudinal axis L through the external conductor contact element 2. The internal conductor contact element pair 4 comprises a first internal conductor contact element 5 and a second internal conductor contact element 6 which both extend along the longitudinal axis L through the dielectric 3.

(36) The plug-in connector components 2, 3, 4 are indicated merely highly schematically and by way of example in all of the figures. Where a following exemplary embodiment of the invention is described without a dielectric 3 (or at least without a dielectric 3 which is formed from a solid body), this is not to be understood as being limiting. In principle, a dielectric 3, or a dielectric 3 which is formed from a solid body, can be provided for each exemplary embodiment, or not.

(37) According to the prior art, it is provided for differential signal transmission, in particular in radiofrequency technology, that the internal conductor contact elements 5, 6 of a common internal conductor contact element pair 4 are of symmetrical and identical design and are arranged in a uniformly distributed manner within the external conductor contact element 2 or the dielectric 3. This is intended to ensure that electrical signal transmission takes place entirely in the “differential mode”.

(38) According to the invention, it is provided that an asymmetry of a plug-in connector component 2, 3, 4 is compensated for by a suitable compensation geometry 8, 9, 11, 12 in the same or in another plug-in connector component 2, 3, 4.

(39) Firstly, it can be provided that the external conductor contact element 2 and/or the dielectric 3 have/has a compensation geometry 8, 9, 11, 12 in order to compensate for an asymmetry of the internal conductor contact element pair 4 with respect to the longitudinal axis L. However, secondly, it can also be provided that the internal conductor contact element pair 4 has a compensation geometry 8, 9, 11, 12 in order to compensate for an asymmetry of the external conductor contact element 2 and/or of the dielectric 3 with respect to the longitudinal axis L.

(40) FIGS. 4 to 27 show advantageous exemplary embodiments or exemplary compensation geometries 8, 9, 11, 12. The features of the exemplary embodiments illustrated can also be combined with one another. In particular, a large number of further compensation geometries for compensating any desired symmetries of any desired plug-in connector components 2, 3, 4 are also possible. The exemplary embodiments are intended to serve only to illustrate a few advantageous measures for producing the symmetry of an electrical plug-in connector using one or more compensation geometries according to the invention.

(41) FIGS. 4 to 6 show a first exemplary embodiment of the invention. In the exemplary embodiment of FIGS. 4 to 6, there is no dielectric 3 or only a gaseous dielectric (generally air). However, a dielectric 3 comprising at least one solid body, as illustrated in FIGS. 1 to 3 or FIGS. 10 to 12 for example, can also be provided.

(42) In the first exemplary embodiment, the internal conductor contact elements 5, 6 of the internal conductor contact element pair 4 are each of different and asymmetrical design and also rotated relative to one another. Owing to the asymmetrical cross-sectional geometry of the internal conductor contact elements 5, 6 and their relative rotation to one another, the second internal conductor contact element 6 of an adjoining inner surface 7 of the external conductor contact element 2 in the region of a central axial section along the longitudinal axis L provides a larger, more capacitively acting surface than the first internal conductor contact element 5. For compensation purposes, a compensation geometry is provided in the external conductor contact element 2 as a material recess 8. The external conductor contact element 2 has a corresponding window parallel to the longitudinal axis L and along the axial extent of the asymmetry of the internal conductor contact elements 5, 6.

(43) In general, the impedances of a first (hypothetical) asymmetrical transmission system and of a second (hypothetical) asymmetrical transmission system can be matched to one another in order to determine the compensation geometry (geometries) 8, 9, 11, 12. In this case, the first asymmetrical transmission system can be defined as a transmission system in which exclusively the first internal conductor contact element 5 is used for signal conduction and the external conductor contact element 2 is used for reference conduction. The second asymmetrical transmission system can be defined as a transmission system in which exclusively the second internal conductor contact element 6 is used for signal conduction and the external conductor contact element 2 is used for reference conduction.

(44) FIGS. 7 to 9 show a second exemplary embodiment of the invention. In this case, the first internal conductor contact element 5 and the second internal conductor contact element 6 have an identical, symmetrical cross-sectional geometry. However, the internal conductor contact element pair 4 of FIGS. 7 to 9 is offset in relation to the axis of symmetry of the external conductor contact element 2 within the external conductor contact element 2 in such a way that the first internal conductor contact element 5 is arranged closer to the inner surface 7 of the external conductor contact element 2 than the second internal conductor contact element 6. The first hypothetical asymmetrical transmission system is therefore more capacitive than the second hypothetical asymmetrical transmission system. According to the invention, the compensation geometry is determined in such a way that the impedances of the two transmission systems are matched to one another. To this end, the compensation geometry runs in the external conductor contact element 2 in a manner adjoining the first internal conductor contact element 5 and is, as in FIGS. 4 to 6, designed as a material recess 8.

(45) As an alternative to the material recess 8, a cross section-widening material deformation 9 of the external conductor contact element 2 can also be provided for example (indicated in dashed lines in FIG. 9).

(46) No dielectric 3, or no dielectric 3 which is formed from a solid body, is provided in the exemplary embodiment illustrated in FIGS. 7 to 9 either. If a dielectric 3 is provided, a compensation geometry can also be formed in the dielectric 3, wherein the dielectric 3 can have a material recess 8 for example between the first internal conductor contact element 5 and the inner surface 7 of the external conductor contact element 2.

(47) FIGS. 10 to 12 illustrate a third exemplary embodiment of the invention. The internal conductor contact elements 5, 6 are, on the other hand, of different, asymmetrical design and rotated in relation to one another. A dielectric 3 which is formed from a solid body is also provided in the exemplary embodiment of FIGS. 10 to 12.

(48) The compensation geometry is formed in the dielectric 3 by suitable material recesses 8 or by two longitudinal slots/grooves. A compensation geometry in the external conductor contact element 2 can be dispensed with as a result. However, a compensation geometry can also additionally be provided in the external conductor contact element 2.

(49) A fourth exemplary embodiment of the invention is illustrated in FIGS. 13 to 15. FIGS. 13 to 15 show an internal conductor contact element pair 4 in which the first internal conductor contact element 5 and the second internal conductor contact element 6 have an identical, but asymmetrical, cross-sectional geometry. This variant is particularly preferred for forming an electrical plug-in connector according to the invention (for example the plug-in connector 10 illustrated in FIG. 27 below).

(50) In order to compensate for the asymmetry, the external conductor contact element 2 has different compensation geometries along the longitudinal axis L which are each designed as a material recess 8. As already mentioned, as an alternative or in addition to a material recess 8, a cross section-widening material deformation 9 can also be provided, as indicated in FIG. 9.

(51) In this case, compensation of the asymmetry takes place by way of example by the four material recesses 8 in the external conductor contact element 2 in the region of the asymmetry of the internal conductor contact elements 5, 6. The axial length of the material recesses 8 is different on both sides of the external conductor contact element 2 in this case.

(52) FIGS. 16 to 18 show a fifth exemplary embodiment of the invention, wherein a configuration of the internal conductor contact elements 5, 6 which is comparable to the exemplary embodiment of FIGS. 4 to 6 is provided. It should be made clear with reference to the fifth exemplary embodiment that, instead of an inductively acting compensation geometry (for example a material recess 8) adjoining the more capacitively acting internal conductor contact element, a capacitively acting compensation geometry adjoining the more inductively acting internal conductor contact element (the second internal conductor contact element 6 in FIGS. 16 to 18) can also be provided. The corresponding compensation geometry can run in the external conductor contact element 2 along the inner surface 7 of the external conductor contact element 2, which inner surface adjoins the second internal conductor contact element 6, and can be designed as a cross section-narrowing material deformation 11.

(53) FIGS. 19 to 21 show a sixth exemplary embodiment of the invention. It should be made clear with reference to FIGS. 19 to 21 that a compensation geometry can also be realized by a composite of different materials. To this end, the dielectric 3 is designed as a composite of two materials 3.1, 3.2, each with a different permittivity, in FIGS. 19 to 21.

(54) A further exemplary embodiment of the invention is illustrated in FIGS. 22 to 24. It should be made clear with reference to FIGS. 22 to 24 that a compensation geometry for a configuration of an internal conductor contact element pair of the type as already illustrated in FIGS. 16 to 18 can also be realized by a material addition 12, that is to say for example a further metal layer within the external conductor contact element 2.

(55) In addition to, or as an alternative to, the described variants of the invention, provision can also be made to reduce the distance between the internal conductor contact elements 5, 6 of the internal conductor contact element pair 4. As a result, concentration of the electromagnetic field lines can advantageously take place.

(56) FIGS. 25 and 26 show an external conductor contact element 2 and two internal conductor contact element pairs 4 for a further electrical plug-in connector. The arrangement of the two internal conductor contact element pairs 4 corresponds to a so-called star quad. However, this arrangement is merely exemplary. A plug-in connector according to the invention can have, in principle, precisely one internal conductor contact element pair 4, as illustrated in FIGS. 1 to 24 and in FIG. 27. However, any desired number of internal conductor contact element pairs 4 can be provided in principle. For example, two, three, four or even more internal conductor contact element pairs 4 can be provided.

(57) The internal conductor contact elements 5, 6 illustrated by way of example in FIGS. 25 and 26 are each of identical, but asymmetrical, design and arranged in a manner distributed around the longitudinal axis L or around the axis of symmetry of the external conductor contact element 2. The external conductor contact element 2 has a suitable compensation geometry (material recesses 8 and material addition 12) in order to ensure symmetrical operation overall.

(58) A material addition 12 can also be designed in one piece in the external conductor contact element 2.

(59) A shielding element which is galvanically connected to the external conductor contact element 2 can optionally run along the longitudinal axis L between the internal conductor contact element pairs 4 (not illustrated).

(60) FIG. 27 shows a cross section through an electrical plug-in connector 10 comprising an external conductor contact element 2, a dielectric 3 and an internal conductor contact element pair 4 according to a preferred embodiment of the invention. However, in principle, the plug-in connector components 2, 3, 4 can also already be referred to in their own right as electrical plug-in connectors within the scope of the invention. By way of example, the electrical plug-in connector 10 of FIG. 27 has a single internal conductor contact element pair 4. However, as already stated, a plurality of internal conductor contact element pairs 4 can also be provided.

(61) In the plug-in connector 10 illustrated in FIG. 27, the internal conductor contact elements 5, 6 of the common internal conductor contact element pair 4 are each of identical, but asymmetrical, design. The illustrated electrical plug-in connector 10 can advantageously be suitable for use in radiofrequency technology solely owing to the compensation geometry according to the invention.

(62) The dielectric 3 and the external conductor contact element 2 have, by way of example, corresponding compensation geometries (material recesses 8 and material additions 12) in order to ensure symmetrical signal transmission through the electrical plug-in connector 10 overall.

(63) In particular, if the electrical plug-in connector 10 or the external conductor contact element 2, the dielectric 3 and/or the internal conductor contact element pair 4 have a comparatively complex geometry, iterative simulations can be provided in order to minimize a DC component during the differential signal transmission and to establish a suitable compensation geometry 8, 9, 11, 12.

(64) FIG. 28 shows an exemplary method sequence for an iterative simulation or for iteratively establishing a compensation geometry 8, 9, 11, 12.

(65) In a first method step S1, the impedance of the first (hypothetical) asymmetrical transmission system can be determined, which transmission system uses the first internal conductor contact element 5 for signal transmission and the external conductor contact element 2 for reference transmission, while the second internal conductor contact element 6 is not allocated to a fixed potential and therefore has a floating potential.

(66) In a second method step S2, the impedance of a second (hypothetical) asymmetrical transmission system can be ascertained, which transmission system uses the second internal conductor contact element 6 for signal conduction and the external conductor contact element 2 for reference conduction, while the first internal conductor contact element 5 is not allocated to a fixed potential and therefore has a floating potential.

(67) In a third method step S3, a compensation geometry 8, 9, 11, 12 in the external conductor contact element 2, in the dielectric 3 and/or in the internal conductor contact element pair 4 can be determined and/or modified with the objective of matching the impedances of the two asymmetrical transmission systems to one another.

(68) The method steps S1, S2, S3 can then be repeated or the impedances of the asymmetrical transmission systems can be determined once again and the compensation geometry (geometries) 8, 9, 11, 12 can optionally be further modified.
