DESCRIPTION OF EXEMPLARY EMBODIMENTS

(19) FIG. 1 shows an illustration of a longitudinal section through one embodiment 1 of a connector arrangement according to the invention with a mating connector inserted.

(20) The connector arrangement 1 according to the invention has a connector 2 and a cable 3 which, at the cable-side end 4 of the connector 2, is mechanically and electrically connected to the connector 2.

(21) The cable 3 is shielded by a shield 51, 52 for a pair of conductors. At the same time, the shield 51 for a pair of conductors forms an external conductor of the cable. This shield 51 for a pair of conductors can be in the form of a wire mesh or in the form of an electrically conductive film-type shield. The end of the shield 51 for a pair of conductors is placed around a supporting sleeve 6 which is fitted onto the shield 51 for a pair of conductors, and the shield 51 for a pair of conductors is axially fixed in relation to the conductors 8 of the cable 3. A cable sheath 7 which is composed of a plastic material and is placed around the shield 51 for a pair of conductors of the cable 3 is arranged in front of the supporting sleeve 6.

(22) A plurality of conductors 8, here a pair of conductors, are guided within the shield 51 for a pair of conductors. The conductors 8 are each encased by a first insulating part 9. The conductors 8 respectively form a core with the respective insulating part 9. The conductors 8 are twisted with one another (twisted pair cable). As an alternative, the conductors 8 can also run in parallel (twin ax(ial) cable). The pair of conductors transmits a differential signal, for example a high-frequency differential signal.

(23) The conductors 8 run in the longitudinal direction L of the cable 3 and are at a first mutual distance X within the cable 3 in the first section 10.

(24) A further shield 52 for a pair of conductors, which initially jointly shields the pair of conductors in the further profile of said pair of conductors, is formed following the shield 51 for a pair of conductors.

(25) The region of the cable 3 as far as the conductor shield 53 therefore forms the first section 10.

(26) In FIG. 1, the intermediate section 13 is subdivided into a widening section, in which the distance between the conductors is increased, and into a shield section, in which the conductors are shielded from one another by the conductor shield 53. The shield section is identical to the intermediate section 13. The widening section is limited to a front part of the intermediate section 13.

(27) The shield 52 for a pair of conductors has a conductor shield 53, which splits the pair of conductors to form individual conductors, between the conductors 8 in a interface-side end region. Therefore, the shield 52 for a pair of conductors is both a shield for a pair of conductors and also a conductor shield in the end region. The conductor shield 53 can be of unipartite design or multipartite design with the shield 52 for a pair of conductors.

(28) Unipartite shields 52, 53 can be cast or inserted and fixed during assembly. Reference is made to FIGS. 8A-8F in respect of exemplary configurations between a conductor shield 53 and a shield 52 for a pair of conductors.

(29) The distance between the individual conductors 8 increases from the first mutual distance X to the greater second mutual distance Y within the shield 52 for a pair of conductors in the intermediate section 13. After this point, the distance between the conductors 8 in the intermediate section 13 remains constant and the conductors 8 run parallel to one another.

(30) In order to avoid or to reduce a possible air gap between the shield 52 for a pair of conductors or the conductor shield 53 and the insulating part 9, the shield 52 for a pair of conductors or conductor shield 53 can be in the form of a unipartite potting compound which surrounds the conductors 8, as far as possible without intermediate spaces. As an alternative, the shield 52 for a pair of conductors or conductor shield 53 can also be produced as a turned, milled or cast part.

(31) The shield 52 for a pair of conductors is electrically connected to the shield 51 for a pair of conductors by means of a conductive crimp sleeve 16. The crimp sleeve 16 is guided coaxially over the supporting sleeve 6 to this end. For the purpose of DC-coupling or electrically connecting the shield 51 for a pair of conductors of the cable 3 to the shield 17 for a pair of conductors of the connector 2, the shield 17 for a pair of conductors is placed over the shield 52 for a pair of conductors which is in turn connected to the shield 51 for a pair of conductors.

(32) The conductors 8 are guided in associated guide channels 18 in the second section 14. The conductors 8 are at the distance Y from one another and are surrounded by an insulating part 19. The conductors 8 are electrically connected to associated internal conductor contact elements 20 within the guide channels 18. The electrical connection can be made, for example, by means of soldering or crimping.

(33) The internal conductor contact elements 20 each have a socket-like recess 23 for receiving an associated contact pin 24 of a mating connector 25 at the connector-side end 22 of the connector 2.

(34) As an alternative, the internal conductor contact elements 20 can also be realized as contact pins and can be inserted into associated socket-like contact elements of the mating connector 25 so as to protrude beyond the interface-side end 22 of the connector 2. The connector 2 can also be realized as a coupler which connects the cable 3 to a further cable.

(35) FIG. 2 shows a further embodiment 1 of a connector arrangement according to the invention in which the shield 5220 for a pair of conductors with the conductor shield 5221 is shorter than in the case of the embodiment above. Accordingly, the shield section and the widening section coincide in the intermediate section. Consequently, the intermediate section is also shorter than in the above embodiments.

(36) FIG. 3 shows a further embodiment 1 of the invention, in which the widening section extends over a part of the shield section similarly to FIG. 1. The shield element 5230 with the conductor shield 5232 and the shield 5231 for a pair of conductors extends over the intermediate section 13 and also over a part of the first section 10. The shield 5231 for a pair of conductors forms a shield case. The conductor shield is in the form of an isolating element which isolates the conductors 8.

(37) For the purpose of axially fixing the internal conductor contact element 20 in the insulating part 19 of the connector 2, the said insulating part has a radially outwardly directed spring element 21 which is respectively supported on an end face of an annular slot in the guide channel 18 within the insulating part 19.

(38) In FIG. 3, there is an intermediate space containing air between the conductors 8 and the conductor shield 5232. It is self-evident that the intermediate space can be adapted in an application-specific manner in accordance with electrical requirements and manufacturing conditions.

(39) FIG. 4 shows an embodiments 1.sup.IV of the invention, with an alternative shield element 5240 with a shield 5242 for a pair of conductors and conductor shield 5241. The shield 5242 for a pair of conductors extends over the entire intermediate section 13. However, the conductor shield 5241 which forms the shield section extends only over a part of the intermediate section 13 and tapers in the widening section 15 so as to form a trapezoid. The shield element 5240 prespecifies the profile of the conductors 8 by the conductor shield 5242 splitting the conductors 8.

(40) It is clear to a person skilled in the art that compensation of the impedance on account of the changing distance can also be performed in a region in which the distance between the conductors is constant, provided that this region is formed immediately adjacent to the region with the changing distance in the intermediate section.

(41) FIG. 5 shows a further embodiment 1.sup.V of the invention, with an alternative shield element 5250 with a shield 5252 for a pair of conductors and conductor shield 5251. The shield 5252 for a pair of conductors extends the entire intermediate section 13. However, the rectangular conductor shield 5251 extends only over a part of the intermediate section and imposes a parallel profile on the conductors 8. The embodiment 1.sup.V enables particularly simple production of the connector arrangement.

(42) FIG. 6 shows a further embodiment 1.sup.VI of the invention, in which the shield element 5260 with the shield 5261 for a pair of conductors and the conductor shield 5262 extends both over parts of the cable 3 and also over parts of the connector 2 for the purpose of further optimization of the transmission characteristics. In this respect, the intermediate section 13 is not limited to the cable 3 or to the connector 2 either.

(43) FIG. 7 shows a further embodiment 1.sup.VII of the invention, in which the shield element 5280 is formed by a shield 5281 for a pair of conductors and also by a conductor shield 5282 which is inserted into the insulating part 19. The insulating part 9 of the conductors 8 ends in front of the intermediate section 13.

(44) The insulating part 19 extends along second section 14 and along the intermediate section 13, serves to insulate the conductors in this region and has a recess, which corresponds to the conductor shield 5272, in the intermediate section. Complex shapes, for example cylindrical shapes, or a recess slot, in which a shielding plate is inserted, are feasible here.

(45) The insulating part 19 can be designed to make contact with the converging conductors 8.

(46) FIG. 8 shows a further embodiment 1.sup.Ix of a connector arrangement according to the invention, in which matching of the impedance Z.sub.odd of the differential mode is performed.

(47) On account of the increasing distance between the two conductors 8 in the intermediate section 13, the capacitance C.sub.12 between the two conductors 8 reduces. As a result, the impedance Z.sub.odd of the differential mode increases.

(48) With regard to matching of the impedance Z.sub.odd of the differential mode between the individual sections, the impedance Z.sub.odd of the differential mode is also likewise artificially increased within the cable 3 in the first section 10. To this end, the distance d1 between the conductors 8 and the shield 51 for a pair of conductors, and therefore the capacitance C.sub.11 between the individual conductors 8 and the shield 51 for a pair of conductors, within the cable 3 is reduced.

(49) The connector 1.sup.IX has a dielectric spacer 27 between the conductors 8. The connector 1.sup.IX has a shield element 5270 with a shield 5271 for a pair of conductors and a conductor shield 5272 in the intermediate section 13. The shield element can be of unipartite or multipartite design.

(50) FIGS. 9A-9F show different configuration comprising a conductor shield and a shield for a pair of conductors.

(51) FIG. 9A shows a further embodiment of the invention with a unipartite shield element 5290 through which the conductors 8 are guided. The shield element forms the outer conductor shield 5291 and also the conductor shield 5292 between the conductors 8.

(52) FIG. 9B shows a further embodiment of the invention with a two-part shield element 5293 which has two symmetrical half-shells 5294. The half-shells 5294 are respectively in the form of a negative in relation to the other half-shell and can additionally have a corresponding surface profile, for example serrated profile. For the purpose of guiding the conductors 8, the half-shells 5294 have semicircular depressions which impose a profile on the conductors 8.

(53) FIG. 9C shows a further embodiment with a shield element 5295 with in each case two symmetrical parts 5296 which are each in the form of a stamped or bent part.

(54) FIG. 9D shows a further embodiment of the invention which is similar to the embodiment according to FIG. 10B. The shield element 5297 has two non-identical shells 5298, 5299 which, when put together, surround the conductors 8.

(55) FIG. 9E shows a further embodiment of the invention with a shield element 5310 which has a conductor shield 5312 and a shield 5311 for a pair of conductors. The conductor shield 5312 surrounds approximately one third of the circumference of the conductors. The shield for a pair of conductors can be designed to follow the profile of the insulated conductors 8 in the widening section and can taper to a point or to a wedge in this region.

(56) FIG. 9F shows an embodiment with a similar shield element 5313 to FIG. 9E with a different conductor shield 5315 with a rectangular basic area which optionally tapers to a point or to a wedge, and with a different shield 5314 for a pair of conductors.

(57) FIG. 10 shows a sectional view of one embodiment of the invention in the intermediate section. The conductors 8 are surrounded by a shield 52 for a pair of conductors. The intermediate space between the conductors 8 together with their insulating parts 9 and the shield 52 for a pair of conductors is filled with air. A conductor shield 53 which also shields the conductors from one another is inserted into the shield 52 for a pair of conductors. By way of example, the conductor shield 53 can be in the form of a plate and inserted into the shield 52 for a pair of conductors by means of a slot.

(58) FIG. 11 shows a further embodiment of the invention. Here, the distance d.sub.1 between the conductors 8 and the shield 51 for a pair of conductors is realized by an additional dielectric spacer 27 in the first section 10. This distance d.sub.1 is greater than the distance d2 between the conductors 8 and the shield element 52 in the intermediate section 13.

(59) A cable 3 is not limited to one pair of conductors, but rather can also have a plurality of pairs of conductors.

(60) According to FIG. 12A, one shield element with a part 5316 which isolates the conductors 8 and a part 5317 which holds the conductors together is provided for, for example, three pairs 8 of conductors.

(61) FIG. 12B likewise shows one shield element with a plurality of parts 5318 which isolate the conductors and a plurality of parts 5319 which hold the conductors 8 together for, for example, three pairs 8 of conductors. It is self-evident that this embodiment can be extended or varied as desired.

(62) FIG. 13A shows the reflection behavior 1303 in the spectral region of a connector arrangement according to the invention, the reflection behavior 1302 of a connector arrangement according to DE 20 2015 000 753 U1 and the reflection behavior 1301 of a connector arrangement without shielding at the transition between cable and connector.

(63) Said figure shows that the reflection factor S.sub.11 of the connector arrangement according to the invention initially undergoes a considerable impairment starting from a frequency f of approximately 7 GHz, while the reflection factor of a connector arrangement without shielding is already considerably impaired starting from a frequency of approximately 0.8 GHz and the reflection factor of a connector arrangement according to DE 20 2015 000 753 U1 is considerably impaired starting from a frequency of approximately 4 GHz.

(64) FIG. 13B shows the pulse behavior 1306 with respect to time t of a connector arrangement according to the invention, the pulse behavior 1305 of a connector arrangement according to DE 20 2015 000 753 U1 and the pulse behavior 1304 of a connector arrangement without shielding at the transition between cable and connector.

(65) The reflective pulse response of the connector arrangement according to the invention in the time range in which the received signal level value is converted into a corresponding impedance value Z is also considerably more severely damped than in a connector arrangement without shielding or in a connector arrangement according to DE 20 2015 000 753 U1.

(66) The invention is not limited to the illustrated embodiments, refinements and subvariants. In particular, all combinations of the features respectively claimed in the individual patent claims, of the features respectively disclosed in the description and of the features respectively shown in the figures of the drawing are also covered by the invention, provided that they are technically expedient.

(67) Although the present invention has been described above entirely on the basis of preferred exemplary embodiments, it is not limited to these, but rather may be modified in a variety of ways.
