Accordingly, the outer conductor can serve as a shield, for example to shield the inner conductor against interference from radiated electromagnetic fields.
  • Two coaxial cables can be connected to one another by coaxial connectors, each of which is attached to one end of one of the coaxial cables, by forming a coaxial connector.
  • both the inner conductors and the outer conductors of the two cables are brought into electrical contact with one another and at the same time it is ensured that there is no interference between the There is always sufficient electrical insulation between the inner conductors and the outer conductors, even within the coaxial connector.
  • the two coaxial connectors are designed with a complementary interface geometry so that they can be mechanically and electrically coupled to one another.
  • One of the two coaxial connectors can be designed as a plug in terms of its interface geometry and the other coaxial connector can be designed as a matching socket.
  • Coaxial connectors have been proposed that are constructed in multiple pieces and whose interface geometry can be variably adapted for different applications.
  • US 10,938,169 B2 A coaxial connector composed of a cable section and an interface section and a method for its manufacture are described.
  • DE 44 34 702 C1 an insulation displacement connection device for a coaxial cable, in particular an angled coaxial cable coupler. It is described that an exposed inner conductor of a coaxial cable is provided with an "IDC contact element" so that the contact element can be arranged in a housing. A pressure piece made of an insulating material is applied to the contact element and pushed onto a head of the contact element. If a screw is tightened, the inner conductor part can be secured in a clamping slot in the pressure piece. A cable-side contact element is described, wherein the cable-side contact element is secured in a cable-side insulator.
  • WO 96/31925 A1 describes a plug-side inner conductor that is arranged in a plug-side insulator and in sections in a cable-side insulator.

What makes pulling out the plug-side inner conductor (in Fig. 1 to the left) is the attachment to the cable-side contact element (and a collar that presses against the right end of the plug-side insulator from an opposite side).

  • the interface section can be designed application-specifically by selecting the outer interface contact, the interface insulator and/or the elongated inner interface contact from a plurality of available respective components such that the interface section has an application-specific geometry with regard to a shape and/or dimensions in order to establish a mechanical and electrical connection with an application-specific mating connector from a plurality of possible mating connectors.
  • the approach proposed here can be used to easily manufacture coaxial connectors of various designs, the interface geometry of which is adapted to different types of mating connectors. While the components of the interface section to be used can vary depending on the application, the same cable section can be used for each application, which simplifies the overall complexity of both the coaxial connector and the process for its manufacture.
  • At least one radially outwardly projecting first projection can be formed on the inner interface contact as the first component and/or at least one radially inwardly projecting second projection can be formed on the cable insulator, in particular on an interface region of the cable insulator, as the second component.
  • a radially outwardly projecting embossing or a radially outwardly projecting ridge can be formed on the inner interface contact as the first projection.

  • Figs. 1 and 2 illustrate a coaxial connector 1 in various sectional views.
  • the coaxial connector 1 comprises a cable section 3 and an interface section 5.
  • the coaxial connector 1 is designed as an angled connector, ie a longitudinal extension direction 19 of the interface section 5 runs perpendicular to a longitudinal extension direction 21 of the cable section 3.
  • the cable section 3 has an outer cable contact 7, a cable insulator 9 and an elongated inner cable contact 11.
  • the outer cable contact 7 is a die-cast component and the inner cable contact 11 is designed as a stamped and bent component made of an electrically conductive metal sheet.
  • the cable insulator 9 is designed as a plastic component.
  • the cable insulator 9 is accommodated in an inner volume surrounded by the outer cable contact 7.
  • the inner cable contact 11 is accommodated in a central recess coaxially within the cable insulator 9 and is spaced radially from the outer cable contact 7 by this and is thus electrically insulated.
  • the inner cable contact 11 is designed as a sleeve tapering from a first end to a second end, which forms a tip 53 at the second end.
  • the inner cable contact 11 is connected to an inner conductor 47 of a coaxial cable 45.
  • the inner cable contact 11 with its first end and the inner conductor 47 can be crimped together, for example.
  • An outer conductor 51 of the coaxial cable 45 is connected to the outer cable contact 7, for example also via a crimp. Between the outer conductor 51 and the inner conductor 47 of the cable 45 there is an insulation layer 49 which electrically separates the two conductors from each other.
  • the interface section 5 has an outer interface contact 13, an interface insulator 15 and an elongated inner interface contact 17.
  • the outer interface contact 13 is a deep-drawn component and the inner interface contact 17 is in turn designed as a stamped and bent component and the interface insulator 15 as a plastic component.
  • the inner interface contact 17 is accommodated coaxially in a central recess, among other things within the interface insulator 15 and is connected, among other things, via this spaced radially from the outer interface contact 13 and thus electrically insulated.
  • the outer interface contact 13, the interface insulator 15 and the inner interface contact 17 are designed with regard to their geometric configuration, i.e. in particular with regard to their dimensions and shapes, such that they form an interface geometry 57 at a free end facing away from the cable section 3, which is designed such that the coaxial connector 1 can be plugged together via its interface section 5 with a correspondingly complementary interface geometry of a mating connector (not shown).
  • the cable section 3 of the coaxial connector 1 has an elongated shape, in which a first opening 31 is formed in a lower region on a lower end face 37 of the outer cable contact 7.
  • the outer cable contact 7 has a circular cross-section and surrounds the first, also circular opening 31 in the form of a sleeve-like wall.
  • the also circular cable 45, together with the inner cable contact 11 attached to it, is inserted into this lower region in an insertion direction (that is, in the figure shown, from bottom to vertically upwards) via the first opening 31.
  • the outer cable contact 7 has a second opening 33 in an upper region on a lateral surface 39.
  • the second opening 33 is circular.
  • the outer cable contact 7 is designed as a housing with a rectangular cross-section.
  • the second opening 33 serves to create an internal connection between the cable section 3 and the interface section 5, which is shielded from the outside by the outer cable contact 7 and the outer interface contact 13.
  • the inner interface contact 17 runs through the second opening 33 from a partial region directed towards the interface geometry 57 to a partial region accommodated in the inner volume in the outer cable contact 7.
  • the outer interface contact 13 is mechanically and electrically connected to the outer cable contact 7.
  • both outer contacts 13, 7 can be mechanically connected to one another in such a way that they cannot be separated, for example by pressing. that after completion of the coaxial connector 1 they can no longer be separated from each other without damage.
  • the outer cable contact 7 further has a third opening 35 in the upper region on the casing surface 39.
  • the third opening 35 is formed opposite the second opening 33 in the casing surface 39 of the outer cable contact 7.
  • the third opening 35 is rectangular. It has a width that essentially corresponds to a width of the outer cable contact 7 in the upper region or is slightly smaller than this.
  • the width of the third opening 35 is the same size or larger than the width of the cable insulator 9 to be accommodated in the inner volume of the outer cable contact 7.
  • a length of the third opening 35 is considerably larger than its width and in particular is the same length or longer than a length of the cable insulator 9.
  • the third opening 35 is closed with an electrically conductive cover 41. Accordingly, the housing formed by the outer cable contact 7 then completely encloses the inner volume together with the cable insulator 9 accommodated therein and the inner cable contact 11 running therein as well as at least a partial area of the inner interface contact 17 protruding into the inner volume, with the exception of the first and second openings 31, 33.
  • the inner interface contact 17 is attached to the cable insulator 9.
  • the inner interface contact 17 is spaced apart from the interface insulator 15 in the radial direction, so that there is no direct contact or even engagement between the two components.
  • the cable insulator 9 has a cable region 27 and an interface region 29.
  • the elongated cable region 27 is designed to accommodate the inner cable contact 11.
  • the cable insulator 9 with its cable region 27 encloses the inner cable contact 11 running centrally therein.
  • the interface region 29, which is also elongated, runs perpendicular to the cable region 27 and is designed to accommodate at least a partial longitudinal region of the inner interface contact 17.
  • the interface region 29 encloses the inner interface contact 17 centrally accommodated therein at least in partial regions thereof.
  • the Interface region 29 of the cable insulator 9 is at least partially surrounded by the interface insulator 15. Accordingly, the interface region 29 of the cable insulator 9 and the interface insulator 15 surrounding it jointly separate and insulate the inner interface contact 17 accommodated therein from the outer interface contact 13.
  • the inner interface contact 17 has one or more locking tabs 23 that project radially outwards.
  • the inner interface contact 17 is provided with two locking tabs 23 that project outwards in opposite directions.
  • the cable insulator 9 accordingly has one or more recesses 25 in its interface area 29, into which the locking tabs 23 of the inner interface contact 17 can engage in a locking manner.
  • the recesses 25 (only in Fig. 2 shown) in the cable insulator 9 at a position which is spaced from an end face 59 of the interface insulator 15 in a direction parallel to the longitudinal extension direction 19 of the inner interface contact 17. Accordingly, the recess 25 in the interface region 29 of the cable insulator 9 is not covered or overlapped by the interface insulator 15. In addition, the recesses 25 are located in a partial region of the interface region 29 which is located within the inner volume surrounded by the outer cable contact 7.
  • a particularly compact coaxial connector 1 can be formed, since, for example, the inner interface contact 17 only needs to protrude slightly beyond the jacket surface 39 or the second opening 33 and thus the interface section 5 can be short.
  • a modified embodiment of a coaxial connector 1 is shown.
  • the modified coaxial connector 1 is designed in terms of its components and features largely the same or similar to the coaxial connector 1 described above. However, it differs in terms of the arrangement and/or design of the locking tabs 23 and the associated recesses 25 from the Figs. 1 and 2 illustrated embodiment.
  • the recesses 25 are provided in the cable insulator 9 at a position which is covered by the interface insulator 15.
  • the recesses 25 are provided at a position which is outside the internal volume surrounded by the outer cable contact 7.
  • the inner interface contact 17 is also spaced apart from the interface insulator 15 in the radial direction, ie its locking tabs 23 engage in the recesses 25 in the interface region 29 of the cable insulator 9, but not in the interface insulator 15. Accordingly, in this embodiment, the inner interface contact 17 can also be attached to the cable insulator 9 independently of the interface insulator 15.
  • the inner interface contact 17 is then attached to the cable insulator 9.
  • the inner interface contact 17 is inserted into the central recess in the interface area 29 of the cable insulator 9 in an insertion direction that corresponds to its longitudinal extension direction 19 and is displaced until its locking tabs 23 snap into the corresponding recesses 25 in the cable insulator 9.
  • the inner interface contact 17 is thus positively attached to the cable insulator 9, in particular in the insertion direction.
  • the cable insulator 9 can then be handled further as a unit 43 together with the inner interface contact 17 locked into it.
  • this unit 43 can be introduced into the inner volume in the outer cable contact 7.
  • the unit 43 can be introduced into the inner volume through the large third opening 35 on a rear side of the outer cable contact 7. (that is, in the Fig. 5 coming from the right), whereby the inner interface contact 17 and the surrounding interface area 29 of the cable insulator 9 protrude outwards on the opposite front side of the outer cable contact 7 through the second opening 33 provided there.
  • the inner cable contact 11 can then be pushed together with the cable 45 already attached to it, for example coming from below through the first opening 31, into the cable insulator 9 already located in the inner volume in the outer cable contact 7.
  • the inner cable contact 11 can be pushed in until its tip 53 engages in a through hole 55 near the rear end of the inner interface contact 17, thereby bringing the inner cable contact 11 into electrical contact with the inner interface contact 17.
  • the outer interface contact 13 can be attached to the outer cable contact 7.
  • the interface insulator 15 can be introduced into the outer interface contact 13 or between the outer interface contact 13 and the inner interface contact 17.
  • the outer interface contact 13 and/or the interface insulator 15 can be pushed into the second opening 33 in the outer cable contact 7 and, for example, irreversibly pressed onto it.
