DETAILED DESCRIPTION OF THE INVENTION

[0036] FIGS. 1 and 2 show an embodiment of a plug-in connector 1 according to the invention, which in this case is designed as an RJ45 plug-in connector, which can be fabricated in the field. In this case, FIG. 1 shows the plug-in connector 1 in the assembled state—but without a data line connected to the plug-in connector 1—while FIG. 2 shows an exploded view of the plug-in connector 1. The plug-in connector 1 has a two-part housing 2 with a housing upper part 2a and a housing lower part 2b. Inside the housing 2, a total of eight connecting elements 3, which are designed here as cutting contacts, and eight contact elements 4 are arranged, wherein in each case, a connecting element 3 is connected in an electrically-conductive manner via a conductor element 5 to a contact element 4. The contact elements 4 are arranged and designed corresponding to corresponding mating contact elements of a jack, not shown here, into which jack the plug-in connector 1 that is designed as a plug can be inserted.

[0037] In the case of the plug-in connector 1 according to the invention, in each case at least one section 6 of the individual conductor elements 5 is designed and arranged in such a way that the characteristic wave impedance of the section 6 is specifically mismatched. This means that the value of the characteristic wave impedance in the section 6 deviates from the rated characteristic wave impedance of the data line, which is to be connected to the plug-in connector 1. In the case of data lines in the EDP networks, the rated characteristic wave impedance is in general 100 Ohm, so that the corresponding sections 6 of the individual conductor elements 5 in each case have a characteristic wave impedance that is greater than or less than 100 Ohm. In the case of the embodiment of the plug-in connector 1 that is depicted in the figures, the connecting elements 3 and the contact elements 4 are arranged on a conductor plate 7, which has multiple strip conductors 8 as conductor elements 5. The conductor plate 7 that is depicted in FIG. 2 is in this case a multi-layer conductor plate, which has a total of four thicknesses or layers, wherein in FIG. 2, only the upper layer of the conductor plate 7 is visible.

[0038] FIGS. 3 and 4 show two different embodiments of the uppermost layer of the conductor plate 7 that is depicted in FIG. 2, once as an overall view and once as an enlarged detailed depiction. In addition to the strip conductors 8 that are arranged on the top of the conductor plate 7 or the uppermost layer of the conductor plate 7, the individual layers of the conductor plate 7 in each case still have a ground surface 9, which is arranged below the strip conductors 8 and is separated from the strip conductors 8 by the corresponding base material of the conductor plate 7.

[0039] The individual strip conductors 8 can be identified in particular by their geometry parameters, which are altered for targeted mismatch of the characteristic wave impedance in the section 6.

[0040] In the case of the embodiment depicted in FIG. 3, in section 6, the widths w of the two strip conductors 8 are decreased, in proportion to the width of a corresponding strip conductor with rated characteristic wave impedance. As a result, the characteristic wave impedance of the section 6 of the strip conductors 8 is greater than the rated characteristic wave impedance, i.e., in this case is greater than 100 Ohm. In addition, in the case of the embodiment depicted in FIG. 3, the distance h between the sections 6 of the two strip conductors 8 and the ground surface 9 is increased; to do this, a corresponding cutout 10 is made in the ground surface 9. Also, increasing the distance h between the sections 6 and the ground surface 9 leads to an increase in the characteristic wave impedance of the sections 6 of the strip conductors 8, so that because of the two above-described measures, the two strip conductors 8 in the area of their sections 6 in each case have a characteristic wave impedance that is, for example, approximately 15% to 20% above the rated characteristic wave impedance.

[0041] In the case of the second embodiment of a conductor plate 7 that is depicted in FIG. 4, the characteristic wave impedance of the sections 6 of the strip conductors 8 is also increased in comparison to the rated characteristic wave impedance. For this purpose, in the case of the embodiment according to FIG. 4, the distance s between the two sections 6 of the two strip conductors 8 that run parallel to one another is increased relative to a match with the rated characteristic wave impedance. This measure can, as depicted in FIG. 4, be carried out together with a reduction in the width w of the two strip conductors 8 in the section 6 or can be carried out as an alternative to the two measures that are depicted in FIG. 3. In principle, it is also possible to combine all measures with one another.

[0042] Another option for altering the characteristic wave impedance of a section 6 of a strip conductor 8 consists in decreasing or increasing the thickness t of the strip conductor 8. In this case, decreasing the thickness t leads to an increase in the characteristic wave impedance, while increasing the thickness t of the strip conductors leads to a decrease in the characteristic wave impedance. The influence of an alteration of the thickness t of the strip conductor on the characteristic wave impedance is, however, less than the influence of an alteration of the width w of the strip conductor. Since, moreover, the manufacturing tolerances for the conductor thicknesses are relatively large, this option of targeted mismatch of the characteristic wave impedance of a strip conductor 8 is in general less well-suited, and in practice thus less simple to implement.

[0043] Finally, it is also evident from FIGS. 3 and 4 that in the case of the two variant embodiments, the sections 6 in the strip conductors 8 can be selected so that the strip conductors 8 run parallel to one another there and do not have any bends. This has the advantage that, as a result, it is possible to avoid further influences on the characteristic wave impedance of the individual strip conductors, which can arise by varying conductor lengths or by the bends.
