- the cable shield 14 is placed around the cable interior in the form of a film, that the two connecting sections 141, 142 of the film overlap in the circumferential direction.
- the cable shield 14 can be opened in a targeted manner if, for example when the cable is being assembled, the interior of the cable is to be accessed.
- the cable shield 14 can be combined with the cable jacket 15 to form a structural unit, e.g. by the cable shield 14 being connected to the cable sheath 15 on its outer surface facing away from the cable interior, for example via an adhesive.
- drain strands 21, 22 are arranged in the interior of the cable, each of which extends together with the wires 11, 12 along the longitudinal direction L of the cable.
- the drain wires 21, 22 are electrically conductive and not insulated, and they are in electrical contact with the cable shield 14.
- Such filler strands 21, 22 serve to place the cable shield 14 in a defined manner at ground potential, and advantageously also when the cable shield 14 is locally damaged, for example in the case of a film, is torn in sections.
- the filler strands 21, 22 can additionally contribute to shielding the interior of the cable.

- a magnet M is approximated for this purpose - after the cable sheath 15 has been cut open at the plug-side cable end - of a respective drain wire 21, 22 at the corresponding cable end.
- a respective drain wire 21, 22 contains a material with such magnetic properties that the drain wire 21, 22 can be separated from the wires 11, 12 of the cable 1 under the influence of magnetic forces. This means that the magnetic properties of the drain wire 21, 22 must differ from those of a respective wire 11, 12.
- FIG Figure 2B By lifting a respective drain wire 21, 22 out of the interior of the cable under the influence of magnetic forces, a foil can be used in FIG Figure 2B shown type formed cable shield 14 are automatically opened.

- a support crimp 16 is applied thereon, which (optionally) can be surrounded by a potting 18, for example in the form of a ferrite-core filter overmolding.
- a cable-side (ferrite core) filter acts here as a sheathed wave filter, in particular for suppressing sheathed waves in the form of high-frequency common mode interference, which are caused, for example, by electrical devices and which run along of cable 1. That filter thus serves to eliminate or reduce common-mode interference which occurs in phase on the two parallel wires 11, 12 or the electrical lines 11a, 12a and which in the present example are caused in particular by jacket waves.
- the connector connected to the end of the cable 1 on the plug side comprises an outer conductor 8, in the exemplary embodiment in the form of an outer tube, which consists of an electrically conductive material and which surrounds the plug in a ring shape in cross section or, in the exemplary embodiment, in a concrete ring shape.

- the slots 81 and 82 extend in the axial direction a of the connector (and thus also along the cable longitudinal direction L) each up to the cable-side axial end of the outer conductor 8 (and form an open end of the respective slot there).
- the components of the connector arranged within the interior of the connector enclosed by the outer conductor 8 comprise first, on the input side (i.e., cable side), electrical contact elements 31, 32 on the cable side, in the present case in the form of contact plates.
- a connection point in the form of a receptacle 33, 34 for an (stripped) electrical line 11a or 12a of the wires 11, 12 of the electrical cable 1 is integrally formed thereon. Since the electrical line 11a, 12a (core) of a respective wire 11, 12 of the cable 1 is fixed in the respectively assigned receptacle 33, 34, there is an electrical contact via that (electrically conductive) receptacle 33 and 34 to a respectively assigned cable-side electrical contact element 31, 32.

- CMC filter common mode choke
- the carrier body 4 serves to hold and position the electrical component 5 within the connector.
- the carrier body 4 is not used for the electrical connection of the component 5. That is, there is no electrical contact between the electrical component 5 and the carrier body 4.

- the cable-side (input-side) contact elements 31, 32 can be connected on the one hand with the output-side contact elements 71, 72 via the electrical component 5 on the other hand, be electrically connected in pairs. That is, each of the cable-side contact elements 31, 32 is connected via the electrical component 5 to exactly one of the output-side contact elements 71, 72, as follows based on FIG Figures 4A and 4B will be explained in more detail.
- an electrical component 5 designed as a common mode filter common mode interference which occurs on the two parallel wires 11, 12 or the electrical lines 11a, 12a (simultaneously) can be eliminated or reduced with such a configuration.
- the carrier body 4 is designed as a carrier bracket.
- the carrier body 4 has a (flat) carrier region 40 which extends (rectilinearly) between a first connecting section 41 and a second connecting section 42.
- the orientation of the carrier region 40 is transverse to the axial direction a of the connector.
- the electrical component 5 is placed on the carrier region 40 of the carrier body 4.
- a support section 43 or 44 of the support body 4 extends from the connection sections 41, 42 on the support area 40 of the support body 4. This runs curved (arc-shaped) in the circumferential direction along the outer conductor 8.
- the two support sections 43, 44 of the carrier body 4 together with the carrier region 40 form an annular contour.
- the carrier region 40 of the carrier body 4 runs in the exemplary embodiment (in the manner of a secant) in a straight line and transversely to the axial direction a between opposite positions of the outer conductor 8.
- the support body 4 penetrates one of the first slots 81 of the outer conductor 8 in the radial direction. That is, the carrier area 40 of the carrier body 4 lies essentially in the interior of the space surrounded by the outer conductor 8, so that in particular the electrical component 5 placed on the carrier body 4 is also arranged in that interior. In the area of its connecting sections 41, 42, however, the carrier body 4 is led radially (in each case through one of the first slots 81) out of the interior of the outer conductor 8.
- the support sections 43, 44 each run arcuately in the circumferential direction along the outer wall of the outer conductor 8. Together, the two support sections 43, 44 grip the outer conductor 8 in the circumferential direction over an angle of approximately 180 °.
- the support sections 43, 44 of the support body 4 each have a free end 43a, 44a, which faces away from the connecting section 41 and 42, at which the respective support section 43 and 44 extends from the support area 40 of the support body 4.
- the free ends 43a, 44a of the support sections 43, 44 face one another and lie opposite one another in order to form the described annular contour together with the carrier region 40.
- the free ends 43a, 44a are (slightly) spaced from one another. In another embodiment, these can also be in contact with one another.
- the drain wires 21, 22 extending from the electrical cable 1 are arranged with their respective free end sections 21a and 22a, so that the second slots 82 are partially closed by the drain wires 21, 22.
- the filler strands 21, 22 can be cohesively fixed within the respective second slot 82, for example by soldering or welding. More information on this is given below using the Figures 5A and 5B are explained.
- a potting compound 85 (potting compound), e.g. in the form of an injection molded part, filled. In the present case, this lies on the inside of the outer conductor 8 facing the inside of the plug and, together with the outer conductor 8, encloses the said components 31-34, 4, 40, 5, 61-64 and 71-74 of the plug connector.
- the potting 85 has channels 86, in which the free end sections 21a, 22a of the drainage strands 21, 22 are received and guided.
- the carrier body 4 - as a (multi) function bracket - can also perform a number of other functions on the plug connector.
- the carrier body 4 serves as a positioning means for positioning the outer conductor 8 on the plug connector.
- the positioning of the outer conductor 8 relative to the carrier body 4 takes place concretely in such a way that the outer conductor 8 with its first slots 81, which are open on the cable side (i.e. at the respective end 81a facing the electrical cable 1), is pushed over the carrier body 4, more precisely over the Connecting sections 41, 42 of the carrier body 4 until the closed end 81b of the respective slot 81 opposite the open cable-side end 81a with the Carrier body 4 engages as in Figure 1B shown. That is, the closed ends 81b of the slots 81 serve as stops for positioning the outer conductor 8 on the carrier body 4 (along the longitudinal direction L of the cable).
- the outer conductor 8 (via the first slots 81) is arranged in a form-fitting manner on the carrier body 4.
- the outer conductor 8 can also be cohesive, e.g. be connected to the carrier body 4 by welding.
- a respective first slot 81 of the outer conductor 8 can be provided with an insertion phase in order to avoid damage to the outer conductor 8 when it is pushed onto the carrier body 4.
- the carrier body 4 can each have axially extended extensions 46 which cover the first slots 81 (in sections), cf. Figure 1B , when the carrier body 4 and the outer conductor 8 are correctly aligned and positioned with respect to one another.
- Such extensions 46 can also serve as guide means for guiding the outer conductor 8 when it is pushed onto the carrier body 4.
- the extensions can act as an EMC labyrinth, ie not only reduce the free line of sight, but also counteract the penetration of electromagnetic waves into the space within the outer conductor 8.
- further functions of the carrier body 4 lie in the tension and pressure relief of the components 31-34, 4, 40, 5, 71-74 of the plug connector arranged in the interior of the outer conductor 8 with the action of forces / torques on the outer conductor 8 and in FIG Tension and pressure relief of the filler strands 21, 22, in particular under the action of torsional forces (along the circumferential direction of the outer conductor 8). This prevents shear off of the filler strands 21, 22.
- a coding housing can also be positioned and locked onto the carrier body 4. Furthermore, for AC decoupling (by means of a capacitor) between the carrier body 4 and the contact elements 31, 32; 71, 72 a capacitor can be arranged.
- Figure 3A shows punched grids from which the components 31-34, 4 and 71-73 of the plug connector arranged within the outer conductor 8, that is to say the cable-side electrical contact elements 31, 32 with the associated receptacles 33, 34, the carrier body 4 with its carrier region 40 and the output side electrical contact elements 71, 72 can be produced with the associated plug elements 73, 74. It can, as in figure 3A also shown, a plurality of such lead frames are provided as endless goods "on the belt".
- the carrier body 4 and the outer conductor 8 are positioned relative to one another as intended, in that the outer conductor 8 rests on the carrier body 4 with the closed ends 81b acting as a stop, of its first slots 81, as in FIG Figure 3B shown, then the final configuration of the components integrated in the lead frame takes place.
- the carrier body 4 by bending into the Figures 1A and 1B transferred state shown in which the support portions 43, 44 extend along the outer circumference of the outer conductor 8.
- the components of the leadframe are separated (for example through assembly windows provided on the outer conductor 8), so that there are a total of five separate elements, namely two separate and spaced apart cable-side connection elements 31, 32, each with a receptacle 33 or 34 integrally molded thereon two separate and spaced-apart output-side electrical connection elements 71, 72, each with a plug element 73 or 74 integrally molded thereon, the latter connection elements 71, 72 also being separated from the first-mentioned connection elements 31, 32 and spaced (axially) apart.
- the carrier body 4 is then also present as the fifth element, which in the exemplary embodiment is separated and spaced from all the electrical connection elements 31, 32, 41, 42.
- the said components 30-34, 4, 71-74 can be separated, for example, by cutting through those components on the lead frame of webs still connecting.

- the annular core 51 is polygonal, specifically rectangular in the exemplary embodiment, and has two windings 52a, 52b. These are arranged on opposite legs of the annular core 51. From each of the two windings 52a, 52b, bond wires 61, 63 and 62, 64 respectively go off, via which in each case a cable-side electrical contact element 31 or 32 is electrically connected to an output-side contact element 71 or 72. In other words, one of the windings 52a, 52b of the electrical component 5 is connected between each of the cable-side contact elements 31, 32 and the associated output-side contact element 71 and 72, respectively.
- the ring-shaped core 53 of the electrical component 5 is designed in the shape of an arc or specifically a ring; so he has none Corners on. Accordingly, the two windings for 54a, 54b each run along an arcuately curved section of the core 53.
- the advantages of the polygonal design of the electrical component 5 are, in particular, simple processability with regard to conveyability and positionability, and simple fixability on the carrier body 4.
- the advantages of the circular design of the electrical component 5 lie in particular in its highly symmetrical structure and in the possibility of large winding lengths.
- FIGS 5A and 5B show a longitudinal section ( Figure 5A ) and a cross section ( Figure 5B ) through the electrical connector from the Figures 1A and 1B , In this way, in particular the arrangement of axially extending extensions 46 of the carrier body 4 in the first slots 81 of the outer conductor 8 on the one hand and the arrangement of the filler strands 21, 22 in the second slots 82 of the outer conductor 8 on the other hand are illustrated.
- the carrier body 4 here represented in particular by the axially extended lateral extensions 46 (in two spatial levels), can serve as a guiding aid when pushing on and positioning the outer conductor 8.
- an EMC labyrinth is formed by covering the first slots 81 of the outer conductor 8 by means of the extensions 46 of the carrier body 4, in particular because of the flanged design of the extensions 46 (which are mushroom-shaped in cross section) in order to prevent electromagnetic waves from penetrating into to prevent the space surrounded by the outer conductor 8.
- Figure 6A shows an exploded view of the electrical connector from the Figures 1A and 1B together with the components directly adjoining it on the cable side, before bending the support sections 43, 44 of the carrier body 4.
- the cable side is in Figure 6 the electrical cable 1 with the wires 11, 12 and their respective core (electrical line 11a or 12a) as well as with the drain wires 21, 22 and with the cable jacket 15.

- the carrier body 4 is designed as with the Figures 1A and 1B described. It forms an inner core of the electrical connector, on which the electrical component 5 (with its housing 50) is arranged, with the electrical contact elements 31, 32; 71, 72 is connected via wires 61, 62, 63, 64.
- the plug connector is surrounded by the outer conductor 8 with the first and second slots 81 and 82, the space between the carrier body 4 - with the exception of the support sections 43, 44 leading to the outside - and the outer conductor 8 being filled by a potting compound 85.
- the assembly of the connector including the connection of the electrical cable 1, can be described as follows: First, the electrical cable 1 is provided and at its free end, to which it is to be connected to the associated electrical connector, with the Support crimp 16 provided. On the electrical cable 1, its drain wires 21, 22 have already been separated, as shown in FIG Figures 2A and 2B described.
- the lead frame is then provided, from which the carrier body 4 and the cable-side and output-side contact elements 31, 32; 71, 72 together with the further components 33, 34; 73, 74 are formed.

- An additional connection is made at the respective contact or engagement area, preferably by material bonding, for example by soldering or welding.
- the electrical component 5 is arranged on the carrier body 4 and fixed there (cohesively) and via the wires 61, 62, 63, 64 to the cable-side and output-side contact elements 31, 32; 71, 72 electrically connected.
- the components defining the interior of the electrical connector namely the carrier body 4 and the contact elements 31, 32; 71, 72 with the further associated components 33, 34; 73, 74 and the electrical component 5 arranged on the carrier body 4, including the associated wires, are then provided with the insulating encapsulation 85 by injection molding to form the channels 86.

Description
Die Erfindung betrifft einen elektrischen Steckverbinder für ein mehradriges elektrisches Kabel nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrical connector for a multi-core electrical cable according to the preamble of
Ein derartiger elektrischer Steckverbinder umfasst mindestens zwei eingangs- bzw. kabelseitige elektrische Kontaktelemente, zum Beispiel in Form von Kontaktplättchen, an die jeweils eine Ader des zugeordneten elektrischen Kabels (über eine geeignete Anschlussstelle) angeschlossen wird, sowie weiterhin mindestens zwei ausgangsseitige elektrische Kontaktelemente, zum Beispiel in Form von Kontaktplättchen, von denen jeweils ein elektrisches Steckerelement, zum Beispiel in Form eines elektrischen leitfähigen Stiftes, abgeht, um hierüber eine elektrische Verbindung mit einem Gegenstecker herstellen zu können.Such an electrical connector comprises at least two electrical contact elements on the input or cable side, for example in the form of contact plates to which one wire of the associated electrical cable is connected (via a suitable connection point), and furthermore at least two electrical contact elements on the output side, for example in the form of contact plates, each of which has an electrical connector element, for example in the form of an electrically conductive pin, in order to be able to establish an electrical connection with a mating connector.
Hierbei handelt es sich um einen klassischen Aufbau eines elektrischen Steckverbinders für mehradrige elektrische Kabel, an den eingangsseitig ein elektrisches Kabel angeschlossen wird und der ausgangsseitig mit elektrischen Steckerelementen versehen ist, um das elektrische Kabel über den Steckverbinder und insbesondere dessen Steckerelemente mit einem Gegenstecker in elektrische Verbindung bringen zu können.This is a classic design of an electrical connector for multi-core electrical cables to which an electrical cable is connected on the input side is and the output side is provided with electrical connector elements in order to be able to bring the electrical cable into electrical connection via the connector and in particular its connector elements with a mating connector.
Zum technischen Hintergrund der Erfindung sei beispielhaft auf die
Der Erfindung liegt das Problem zugrunde, einen elektrischen Steckverbinder der eingangs genannten Art im Hinblick auf die vorbeschriebenen Anforderungen zu verbessern.The invention is based on the problem of improving an electrical connector of the type mentioned at the outset with regard to the requirements described above.
Dieses Problem wird erfindungsgemäß durch die Schaffung eines elektrischen Steckverbinders mit den Merkmalen des Anspruchs 1 gelöst.This problem is solved according to the invention by creating an electrical connector with the features of
Danach ist bei einem gattungsgemäßen elektrischen Steckverbinder vorgesehen, dass zwischen den kabelseitigen (eingangsseitigen) elektrischen Kontaktelementen des Steckverbinders einerseits und dessen ausgangsseitigen elektrischen Kontaktelementen andererseits ein Trägerkörper angeordnet ist, der ein elektrisches Bauelement trägt, über das die mindestens zwei kabelseitigen und die mindestens zwei ausgangsseitigen Kontaktelemente elektrisch miteinander verbunden sind, wobei der Trägerkörper von den kabelseitigen Kontaktelementen und den ausgangsseitigen Kontaktelementen jeweils berührungslos beabstandet ist und das elektrische Bauelement über Bond-Drähte einerseits mit den kabelseitigen Kontaktelementen und andererseits mit den ausgangsseitigen Kontaktelementen elektrisch verbunden ist. Dies kann insbesondere derart erfolgen, dass jedes kabelseitige Kontaktelement mit einem ausgangsseitigen Kontaktelement elektrisch verbunden ist und die einzelnen (hieraus resultierenden) elektrischen Verbindungen parallel zueinander geschaltet sind.According to a generic electrical connector, it is provided that between the cable-side (input-side) electrical contact elements of the connector, on the one hand, and its output-side electrical contact elements, on the other, a carrier body is arranged, which carries an electrical component via which the at least two cable-side and the at least two output-side contact elements are electrically connected to one another, the carrier body being spaced apart from the cable-side contact elements and the output-side contact elements and the electrical component being electrically connected via bond wires on the one hand to the cable-side contact elements and on the other hand to the output-side contact elements. This can take place in particular in such a way that each cable-side contact element is electrically connected to an output-side contact element and the individual (resulting from this) electrical connections are connected in parallel to one another.
Die erfindungsgemäße Lösung erlaubt die Anordnung mindestens eines elektrischen Bauelementes an der Eingangsseite eines Steckverbinders, zwischen dem an den Steckverbinder angeschlossenen elektrischen Kabel und den ausgangsseitigen Kontaktelementen des Steckverbinders, von denen dessen Steckerelemente abstehen. Der Begriff "elektrisches Bauelement" soll dabei aktive elektrische Bauelemente ebenso wie passive elektrische Bauelemente umfassen. Unter einem passiven elektrischen Bauelement wird vorliegend ein elektrisches (insbesondere auch elektronisches) Bauelement verstanden, welches keine Verstärkungsfunktion aufweist und durch das keine Steuerungsfunktion erfüllbar ist. Insbesondere sind derartige passive elektrische Bauelemente in der Lage, ohne externe Stromversorgung zu arbeiten. Insbesondere kann daher unter dem Begriff "passives elektrisches Bauelement" ein Bauelement verstanden werden, dessen Widerstandswert oder elektrische Leitfähigkeit nicht durch einen äußeren angelegten Strom oder durch eine äußere angelegte Spannung beeinflusst wird.The solution according to the invention allows the arrangement of at least one electrical component on the input side of a connector, between the electrical cable connected to the connector and the output-side contact elements of the connector, from which the connector elements protrude. The The term “electrical component” is intended to include active electrical components as well as passive electrical components. In the present case, a passive electrical component is understood to mean an electrical (in particular also electronic) component which has no amplification function and through which no control function can be performed. In particular, such passive electrical components are able to work without an external power supply. In particular, the term “passive electrical component” can therefore be understood to mean a component whose resistance value or electrical conductivity is not influenced by an externally applied current or by an externally applied voltage.
Das passive elektrische Bauelement kann insbesondere als ein Filterelement ausgeführt sein, z.B. als ein Gleichtaktfilter ("Common Mode Choke"/CMC). Es kann zudem ein elektrisch isolierendes Gehäuse aufweisen.The passive electrical component can in particular be designed as a filter element, e.g. as a common mode choke (CMC) filter. It can also have an electrically insulating housing.
Weiter kann das passive elektrische Bauelement einen magnetischen Kern aufweisen, der z.B. ringförmig ausgeführt ist (und der entlang einer mehreckigen Kontur verläuft oder kreisringförmig ausgestaltet ist). Auf den magnetischen Kern können zwei voneinander beabstandete elektrische Wicklungen aufgebracht sein, wobei über jede der Wicklungen jeweils eines der kabelseitigen Kontaktelemente mit einem der ausgangsseitigen Kontaktelemente elektrisch verbunden ist.Furthermore, the passive electrical component can have a magnetic core, which e.g. is designed in a ring shape (and which runs along a polygonal contour or is designed in a circular shape). Two mutually spaced electrical windings can be applied to the magnetic core, one of the cable-side contact elements being electrically connected to one of the output-side contact elements via each of the windings.
Der Trägerkörper kann einen Trägerbereich bilden, der sich von einem ersten Verbindungsabschnitt zu einem zweiten Verbindungsabschnitt erstreckt und auf den das elektrische Bauelement aufgesetzt ist, wobei von dem Trägerbereich an jedem der beiden Verbindungsabschnitte jeweils ein Stützabschnitt des Trägerkörpers derart abgehen kann, dass der Trägerbereich und die beiden Stützabschnitte eine ringförmig umlaufende Struktur bilden.The support body can form a support area which extends from a first connection section to a second connection section and onto which the electrical component is placed, wherein a support section of the support body can extend from the support area at each of the two connection sections such that the support area and the form a circular circumferential structure in both support sections.
Der Steckverbinder kann einen von einem Außenleiter umschlossenen Innenraum aufweisen, in dem der Trägerkörper, das passive elektrische Bauelement sowie die kabelseitigen und ausgangsseitigen Kontaktelemente zumindest abschnittsweise angeordnet sind. Der Außenleiter kann dabei an dem Trägerkörper festgelegt sein. Und der von dem Außenleiter umschlossene Innenraum kann mit einer Vergussmasse befüllt sein.The plug connector can have an inner space enclosed by an outer conductor, in which the carrier body, the passive electrical component and the cable-side and output-side contact elements are arranged at least in sections. The outer conductor can be fixed on the carrier body. And the interior enclosed by the outer conductor can be filled with a potting compound.
Weiterhin kann der Trägerköper durch erste Schlitze des Außenleiters hindurch mit seinen Stützabschnitten aus dem Innenraum das Außenleiters herausgeführt sein, und es können die Stützabschnitte des Trägerkörpers den Außenleiter außenseitig umschließen.Furthermore, the support body can be led through the first slots of the outer conductor with its support sections out of the interior of the outer conductor, and the support sections of the support body can enclose the outer conductor on the outside.
Eingangsseitig des Steckverbinders kann ein das elektrische Kabel umschließendes Filterbauteil angeordnet sein, welches z.B. als ein Ferrit-Kern-Filter ausgebildet ist und welches als Mantelwellenfilter fungieren kann, insbesondere zur Unterdrückung von Mantelwellen in Form hochfrequenter Gleichtaktstörungen, die in der Regel durch elektrische Geräte verursacht werden und die sich entlang des elektrischen Kabels ausbreiten.A filter component enclosing the electrical cable, which e.g. is designed as a ferrite core filter and which can act as a sheathed wave filter, in particular for suppressing sheathed waves in the form of high-frequency common mode interference, which are usually caused by electrical devices and which propagate along the electrical cable.

Die Figuren
Die Adern 11, 12 des Kabels 1 sind gemeinsam in einem durch einen in Kabellängsrichtung L verlaufenden Kabelmantel 15 definierten und von diesem im Querschnitt ringförmig umschlossenen Kabelinnenraum angeordnet. Der Kabelmantel 15 besteht dabei aus einem elektrisch isolierenden Material.The

Schirmgeflechte werden insbesondere zur Abschirmung bei vergleichsweise niedrigen Frequenzen und Kabelschirme in Form von Folien zur Abschirmung bei vergleichsweise hohen Frequenzen (1 MHz bis 10 GHz) verwendet.Shield braids are used in particular for shielding at comparatively low frequencies and cable shields in the form of foils for shielding at comparatively high frequencies (1 MHz to 10 GHz).
Der Kabelschirm 14 kann mit dem Kabelmantel 15 zu einer Baueinheit zusammengefasst sein, z.B. indem der Kabelschirm 14 an seiner dem Kabelinneren abgewandten äußeren Oberfläche mit dem Kabelmantel 15 verbunden ist, etwa über ein Klebemittel.The
Zusätzlich zu den Adern 11, 12 sind im Kabelinneren vorliegend Beilauflitzen 21, 22 angeordnet, die sich jeweils gemeinsam mit den Adern 11, 12 entlang der Kabellängsrichtung L erstrecken. Die Beilauflitzen 21, 22 sind elektrisch leitfähig und dabei nicht isoliert, und sie stehen mit dem Kabelschirm 14 in elektrischem Kontakt. Derartige Beilauflitzen 21, 22 dienen dazu, den Kabelschirm 14 definiert auf Massepotenzial zu legen, und zwar vorteilhaft auch dann, wenn der Kabelschirm 14 lokal beschädigt ist, etwa im Fall einer Folie abschnittweise eingerissen ist. Weiterhin können die Beilauflitzen 21, 22 zusätzlich zur Abschirmung des Kabelinneren beitragen.In addition to the

Gemäß einer Variante besteht dabei eine jeweilige Beilauflitze 21, 22 vollständig aus einem elektrisch leitfähigen ferromagnetischen Material. Gemäß einer anderen Variante weist eine jeweilige Beilauflitze 21, 22 mindestens einen aus einem ferromagnetischen Material bestehenden Kern auf, der von einem elektrisch leitfähigen Material umgeben ist. Diese Ausführungsform ermöglicht eine Optimierung einerseits des Kerns einer jeweiligen Beilauflitze 21, 22 mit Blick auf die magnetischen Eigenschaften und die Optimierung des äußeren leitenden Bereiches einer jeweiligen Beilauflitze 21, 22 mit Blick auf die elektrischen Eigenschaften (auch mit Blick auf den Skin-Effekt bei hohen Frequenzen). So kann eine jeweilige Beilauflitze 21, 22 etwa durch einen Kern aus Stahl gebildet sein, der mit Kupfer beschichtet ist. Das Beschichten kann beispielsweise durch Galvanisieren erfolgen.According to a variant, a

Maßgeblich für das beschriebene Verfahren ist, dass eine jeweilige Beilauflitze 21, 22 ein Material mit derartigen magnetischen Eigenschaften enthält, dass sich die Beilauflitze 21, 22 unter dem Einfluss magnetischer Kräfte von den Adern 11, 12 des Kabels 1 separieren lässt. D.h., die magnetischen Eigenschaften der Beilauflitze 21, 22 müssen sich von denjenigen einer jeweiligen Ader 11, 12 unterscheiden.It is decisive for the described method that a

Am steckerseitigen Ende des Kabels 1 ist hierauf ein Stützcrimp 16 aufgebracht, der (optional) von einem Verguss 18, zum Beispiel in Form einer Ferrit-Kern-Filter-Umspritzung, umgeben sein kann. Ein solcher kabelseitiger (Ferrit-Kern-)Filter fungiert hier als Mantelwellenfilter, insbesondere zur Unterdrückung von Mantelwellen in Form hochfrequenter Gleichtaktstörungen, die z.B. durch elektrische Geräte verursacht werden und die sich entlang des Kabels 1 ausbreiten. Jener Filter dient somit zur Eliminierung bzw. Reduzierung von Gleichtaktstörungen, die an den beiden parallelen Adern 11, 12 bzw. den elektrischen Leitungen 11a, 12a gleichphasig auftreten und die im vorliegenden Beispiel insbesondere durch Mantelwellen hervorgerufen werden.On the plug-side end of the
Der sich an das steckerseitige Ende des Kabels 1 anschließende Steckverbinder umfasst einen Außenleiter 8, im Ausführungsbeispiel in Form eines Außenrohres, der aus einem elektrisch leitfähigen Material besteht und der den Stecker im Querschnitt ringförmig bzw. im Ausführungsbeispiel konkret kreisringförmig umgibt. Der Außenleiter 8 erstreckt sich entlang einer Längsrichtung (Kabellängsrichtung L), d.h., axial, von einem ersten, kabelseitigen Ende 8a zu einem zweiten, ausgangsseitigen Ende 8b. Er kann mit dem Stützcrimp 16 verbunden sein, z.B. stoffschlüssig (durch Schweißen).The connector connected to the end of the
Der Außenleiter 8 weist ein Paar erster Schlitze 81 sowie ein Paar zweiter Schlitze 82 auf. Die Schlitze 81 bzw. 82 eines jeweiligen Schlitzpaares sind vorliegend jeweils einander gegenüberliegend am Außenleiter 8 angeordnet. Außerdem sind die Schlitze 81 des ersten Schlitzpaares relativ zu Schlitzen 82 des zweiten Schlitzpaares im Ausführungsbeispiel entlang der Umfangsrichtung des Außenleiters 8 jeweils um 90° versetzt angeordnet.The
Die Schlitze 81 und 82 erstrecken sich dabei in axialer Richtung a des Steckverbinders (und damit auch entlang der Kabellängsrichtung L) jeweils bis zu dem kabelseitigen axialen Ende des Außenleiters 8 (und bilden dort ein offenes Ende des jeweiligen Schlitzes).The
Die innerhalb des von dem Außenleiter 8 umschlossenen Innenraumes des Steckverbinders angeordneten Komponenten des Steckverbinders umfassen eingangsseitig (d.h., kabelseitig) erste, kabelseitige elektrische Kontaktelemente 31, 32, vorliegend in Form von Kontaktplättchen. An diese ist jeweils einstückig eine Anschlussstelle in Form einer Aufnahme 33, 34 für eine (abisolierte) elektrische Leitung 11a bzw. 12a der Adern 11, 12 des elektrischen Kabels 1 angeformt. Indem die elektrische Leitung 11a, 12a (Seele) einer jeweiligen Ader 11, 12 des Kabels 1 in der jeweils zugeordneten Aufnahme 33, 34 festgelegt wird, besteht über jene (elektrisch leitfähige) Aufnahme 33 bzw. 34 ein elektrischer Kontakt zu einem jeweils zugeordneten kabelseitigen elektrischen Kontaktelement 31, 32.The components of the connector arranged within the interior of the connector enclosed by the
Ausgangsseitig (und von den kabelseitigen Kontaktelementen 31, 32 in axialer Richtung a beabstandet) weist der Steckverbinder (in dem von dem Außenleiter 8 umschlossenen Innenraum) zweite, ausgangsseitige Kontaktelemente 71, 72 auf, an denen jeweils ein Steckerelement 73 bzw. 74, vorliegend in Form eines Steckerstiftes, angeformt ist, über welches der Steckverbinder mit einem Gegenstecker elektrisch verbindbar ist. Die Steckerelemente 73, 74 stehen dabei im Ausführungsbeispiel in axialer Richtung a von dem zugehörigen ausgangsseitigen Kontaktelement 71 bzw. 72 ab.On the output side (and at a distance from the cable-
Zwischen den kabelseitigen Kontaktelementen 31, 32 und den ausgangsseitigen Kontaktelementen 71, 72 (und von diesen jeweils berührungslos beabstandet) ist ein Trägerkörper 4 angeordnet. Der Trägerkörper 4 trägt ein elektrisches Bauelement 5, zum Beispiel in Form eines elektrischen Filterelementes. Der Begriff "elektrisches Bauelement" soll dabei ausdrücklich auch elektronische Bauelemente und insbesondere halbleitende Bauelemente umfassen; weiterhin aktive elektrische Bauelemente ebenso wie passive elektrische Bauelemente. Insbesondere kann es sich bei dem elektrischen Bauelement um einen passiven elektrischen Filter, wie z.B. einen Gleichtaktfilter ("common mode choke"/CMC-Filter), handeln.A
Der Trägerkörper 4 dient dabei zur Halterung und Positionierung des elektrischen Bauelementes 5 innerhalb des Steckverbinders. Der Trägerkörper 4 dient demgegenüber nicht der elektrischen Anbindung des Bauelementes 5. D.h., es besteht kein elektrischer Kontakt zwischen dem elektrischen Bauelement 5 und dem Trägerkörper 4. Auch weist der Trägerkörper 4 keine Leiterbahnen oder sonstige Elemente auf, über welche dem elektrischen Bauelement 5 elektrische Signale zugeführt oder abgenommen werden. Nichtsdestotrotz kann der Trägerkörper 4 auch aus einem elektrisch leitfähigen Material bestehen, insbesondere, wenn das elektrische Bauelement 5 in einem isolierenden Gehäuse aufgenommen ist. Dabei kann das elektrische Bauelement 5 über sein Gehäuse stoffschlüssig, z.B. durch Löten, Schweißen oder Kleben, mit dem Trägerkörper 4 verbunden sein.The
Das elektrische Bauelement 5 ist über Bond-Drähte 61, 62, 63, 64 einerseits mit den kabelseitigen Kontaktelementen 31, 32 und andererseits mit den ausgangsseitigen Kontaktelementen 71, 72 elektrisch verbunden. Dies bedeutet, dass die Adern 11, 12 des elektrischen Kabels 1 jeweils über das elektrische Bauelement 5 mit den Steckerelementen 73, 74 des Steckverbinders elektrisch verbunden sind. Elektrische Signale, die dem Steckverbinder über die Adern 11, 12 des Kabels 1 zugeführt werden, passieren somit das elektrische Bauelement 5, bevor sie über die Steckerelemente 73, 74 an einen Gegenstecker und damit an eine dem Gegenstecker zugeordnete elektrische Baugruppe ausgegeben werden.The
Insbesondere können über das elektrische Bauelement 5 die kabelseitigen (eingangsseitigen) Kontaktelemente 31, 32 einerseits mit den ausgangsseitigen Kontaktelementen 71, 72 andererseits jeweils paarweise elektrisch verbunden sein. D.h., jedes der kabelseitigen Kontaktelemente 31, 32 ist über das elektrische Bauelement 5 mit jeweils genau einem der ausgangsseitigen Kontaktelemente 71, 72 verbunden, wie nachfolgend anhand der
Der Trägerkörper 4 ist vorliegend als ein Trägerbügel ausgeführt. Zur Aufnahme des elektrischen Bauelementes des 5 weist der Trägerkörper 4 einen (ebene) Trägerbereich 40 auf, der sich (geradlinig) zwischen einem ersten Verbindungsabschnitt 41 und einem zweiten Verbindungsabschnitt 42 erstreckt. Die Ausrichtung des Trägerbereiches 40 ist dabei im Ausführungsbeispiel quer zu der axialen Richtung a des Steckverbinders. Auf den Trägerbereich 40 des Trägerkörpers 4 ist das elektrische Bauelement 5 aufgesetzt.In the present case, the
Von den Verbindungsabschnitten 41, 42 an dem Trägerbereich 40 des Trägerkörpers 4 geht jeweils ein Stützabschnitt 43 bzw. 44 des Trägerkörpers 4 ab. Dieser verläuft gekrümmt (bogenförmig) in Umfangsrichtung entlang des Außenleiters 8. Die beiden Stützabschnitte 43, 44 des Trägerkörpers 4 bilden zusammen mit dem Trägerbereich 40 eine ringförmige Kontur. Der Trägerbereich 40 des Trägerkörpers 4 verläuft dabei im Ausführungsbeispiel (nach Art einer Sekante) geradlinig und quer zu der axialen Richtung a zwischen gegenüberliegenden Stellen des Außenleiters 8.A
Im Bereich des ersten und zweiten Verbindungsabschnittes 41, 42 des Trägerbereiches 40 durchdringt der Trägerkörper 4 jeweils einen der ersten Schlitze 81 des Außenleiters 8 in radialer Richtung. D.h., des Trägerbereiches 40 des Trägerkörpers 4 liegt im Wesentlichen im Inneren des von dem Außenleiter 8 umgebenen Raumes, so dass insbesondere das auf den Trägerkörper 4 aufgesetzte elektrische Bauelement 5 ebenfalls in jenem Innenraum angeordnet ist. Im Bereich seiner Verbindungsabschnitte 41, 42 ist der Trägerkörper 4 jedoch radial (jeweils durch einen der ersten Schlitze 81 hindurch) aus dem Innenraum des Außenleiters 8 hinausgeführt.In the area of the first and second connecting
Die von den Verbindungsabschnitten 41, 42 abgehenden Stützabschnitte 43, 44 des Trägerkörpers 4 erstrecken sich dementsprechend außerhalb des von dem Außenleiter 8 umschlossenen Raumes. Die Stützabschnitte 43, 44 verlaufen dabei im Ausführungsbeispiel jeweils bogenförmig in Umfangsrichtung entlang der Außenwand des Außenleiters 8. Gemeinsam umgreifen die beiden Stützabschnitte 43, 44 den Außenleiter 8 dabei in Umfangsrichtung über einen Winkel von etwa 180°.The supporting
Die Stützabschnitte 43, 44 des Trägerkörpers 4 weisen jeweils ein freies Ende 43a, 44a auf, welches dem Verbindungsabschnitt 41 bzw. 42 abgewandt ist, an welchem der jeweilige Stützabschnitt 43 bzw. 44 von dem Trägerbereich 40 des Trägerkörpers 4 abgeht. Die freien Enden 43a, 44a der Stützabschnitte 43, 44 sind einander zugewandt und liegen einander gegenüber, um gemeinsam mit dem Trägerbereich 40 die beschriebene ringförmige Kontur zu bilden. Im Ausführungsbeispiel sind die freien Enden 43a, 44a (geringfügig) voneinander beabstandet. In einer anderen Ausführungsform können diese auch aneinander anliegen.The
In den zweiten Schlitzen 82 des Außenleiters 8 sind die von dem elektrischen Kabel 1 abgehenden Beilauflitzen 21, 22 mit ihrem jeweiligen freien Endabschnitt 21a bzw. 22a angeordnet, sodass die zweiten Schlitze 82 durch die Beilauflitzen 21, 22 teilweise verschlossen sind. Die Beilauflitzen 21, 22 können dabei innerhalb des jeweiligen zweiten Schlitzes 82 stoffschlüssig, zum Beispiel durch Löten oder Schweißen, festgelegt sein. Näheres hierzu wird weiter unten anhand der
Der Raum zwischen dem Außenleiter 8 und den darin angeordneten Komponenten 31-34, 4, 40, 5, 61-64 und 71-74 des Steckverbinders ist teilweise durch einen Verguss 85 (Vergussmasse), z.B. in Form eines Spritzgussteiles, befüllt. Dieser liegt vorliegend auf der dem Steckerinneren zugewandten Innenseite des Außenleiters 8 und umschließt gemeinsam mit dem Außenleiter 8 die besagten Komponenten 31-34, 4, 40, 5, 61-64 und 71-74 des Steckverbinders. Der Verguss 85 weist Kanäle 86 auf, in welchen die freien Endabschnitte 21a, 22a der Beilauflitzen 21, 22 aufgenommen und geführt sind.The space between the
Neben der bereits beschriebenen Funktionen als Halter für das elektrische Bauelement 5 kann dem Trägerkörper 4 - als (Multi-)Funktionsbügel - an dem Steckverbinder noch eine Mehrzahl weiterer Funktionen zukommen.In addition to the functions already described as a holder for the
So dient der Trägerkörper 4 vorliegend als ein Positioniermittel zur Positionierung des Außenleiters 8 am Steckverbinder. Die Positionierung des Außenleiters 8 relativ zu dem Trägerkörper 4 erfolgt dabei konkret in der Weise, dass der Außenleiter 8 mit seinen kabelseitig (also am jeweiligen dem elektrischen Kabel 1 zugewandten Ende 81a) offenen ersten Schlitzen 81 über den Trägerkörper 4 geschoben wird, genauer über die Verbindungsabschnitte 41, 42 des Trägerkörpers 4, bis das dem offenen kabelseitigen Ende 81a gegenüberliegende geschlossene Ende 81b des jeweiligen Schlitzes 81 mit dem Trägerkörper 4 in Eingriff tritt, wie in
Zugleich ist der Außenleiter 8 (über die ersten Schlitze 81) im Ergebnis formschlüssig am Trägerkörper 4 angeordnet. Der Außenleiter 8 kann zudem auch stoffschlüssig, z.B. durch Schweißen, mit dem Trägerkörper 4 verbunden sein.At the same time, the outer conductor 8 (via the first slots 81) is arranged in a form-fitting manner on the
An seinem offenen, kabelseitigen Ende 81a kann ein jeweiliger erster Schlitz 81 des Außenleiters 8 mit einer Einführphase versehen sein, um eine Beschädigung des Außenleiters 8 beim Aufschieben auf den Trägerkörper 4 zu vermeiden.At its open, cable-
Gemäß einer Weiterbildung der Erfindung kann der Trägerkörper 4 jeweils axial erstreckte Fortsätze 46 aufweisen, welche die ersten Schlitze 81 (abschnittsweise) überdecken, vgl.
Weitere Funktionen des Trägerkörpers 4 liegen im Ausführungsbeispiel in der Zug- und Druckentlastung der im Innenraum des Außenleiters 8 angeordneten Komponenten 31-34, 4, 40, 5, 71-74 des Steckverbinders bei der Wirkung von Kräften/Drehmomenten am Außenleiter 8 sowie in der Zug -und Druckentlastung der Beilauflitzen 21, 22, insbesondere unter der Wirkung von Torsionskräften (entlang der Umfangsrichtung des Außenleiters 8). Hierdurch lässt sich ein Abscheren der Beilauflitzen 21, 22 verhindern.In the exemplary embodiment, further functions of the
An dem Trägerkörper 4 kann zudem ein Kodier-Gehäuse positioniert und eingerastet werden. Weiterhin kann zur AC-Entkopplung (mittels Kondensator) zwischen dem Trägerkörper 4 und den Kontaktelementen 31, 32; 71, 72 ein Kondensator angeordnet werden.A coding housing can also be positioned and locked onto the

Zum Einbau der in das Stanzgitter integrierten Komponenten 31-34, 4 und 71-74 in den Steckverbinder kann dessen Außenleiter 8 über die seitlich abstehende Flügel des Trägerkörpers 4 (also die späteren Verbindungs- und Stützabschnitte 41, 43; 42, 44) geschoben werden, vergleiche
Wenn der Trägerkörper 4 und der Außenleiter 8 bestimmungsgemäß zueinander positioniert sind, indem der Außenleiter 8 mit den als Anschlag wirkenden geschlossenen Enden 81b seiner ersten Schlitze 81 am Trägerkörper 4 anliegt, wie in
Weiterhin werden die Komponenten des Stanzgitters (zum Beispiel durch am Außenleiter 8 vorgesehene Montagefenster hindurch) vereinzelt, sodass insgesamt fünf separate Elemente vorliegen, nämlich zwei voneinander getrennte und voneinander beabstandete kabelseitige Anschlusselemente 31, 32 mit jeweils einer einstückig hieran angeformten Aufnahme 33 bzw. 34 sowie zwei voneinander getrennte und voneinander beabstandete ausgangsseitige elektrische Anschlusselemente 71, 72 mit jeweils einem einstückig hieran angeformten Steckerelement 73 bzw. 74, wobei die letztgenannten Anschlusselemente 71, 72 außerdem von den erstgenannten Anschlusselementen 31, 32 separiert und (axial) beabstandet angeordnet sind. Als fünftes Element, welches im Ausführungsbeispiel von sämtlichen elektrischen Anschlusselementen 31, 32, 41, 42 separiert und beabstandet ist, liegt dann noch der Trägerkörper 4 vor.Furthermore, the components of the leadframe are separated (for example through assembly windows provided on the outer conductor 8), so that there are a total of five separate elements, namely two separate and spaced apart cable-
Das Vereinzeln der besagten Komponenten 30-34, 4, 71-74 kann zum Beispiel mittels Durchtrennen jene Komponenten am Stanzgitter zunächst noch verbindender Stege erfolgen.The said components 30-34, 4, 71-74 can be separated, for example, by cutting through those components on the lead frame of webs still connecting.
