- 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 protrude its connector elements.
- the carrier body especially the holder of the (at least one) electrical component is used, but not its electrical contact, this can be targeted with respect to that function, ie, with regard to its mechanical properties, optimized.
- the carrier body can be designed specifically for reliable absorption of forces, such as torsional forces, and it can serve as a stop and locking means for other components, such as for an outer conductor of the connector.
- the carrier body forms on the one hand a carrier region, which extends from a first connecting portion to a second connecting portion and on which the electrical component is mounted, on the other hand from each of the two connecting portions of the carrier region in each case a support portion of the carrier body such that the carrier region and the two support sections form a ring-shaped (eg bow-shaped) circumferential structure.

- the support sections of the carrier body can enclose the outer conductor sections on the outside.
- the support sections of the carrier body are advantageously bent over only after the carrier body has been arranged with its carrier region and the electrical component mounted thereon within the space enclosed by the outer conductor and the support sections of the carrier body have been made of the outer conductor, for example through slots of the outer conductor.
- the input side (cable side) and the output side electrical contact elements and further the support body for the electrical component as components of a single, integrally molded component, for example in the form of a stamped grid, manufactured and integrated into the connector.
- the lead frame is separated into the separate components "input side (cable side) electrical contact elements", “output side electrical contact elements” and “carrier body”, so that the individual cable-side contact elements and the output-side contact elements and the carrier body are present as separate components, not (electrically) connected to each other.
- the figures Figure 1A and 1B show an electrical connector to the input side FIG. 2A shown in cross-section - multi-core electrical cable 1 is connected and the output side electrical connector elements 73, 74 for establishing an electrical connection with a mating connector.
- the electrical cable 1 is designed in the embodiment as a two-core electrical cable.
- the two wires 11, 12 of the cable 1 run along the cable longitudinal direction L side by side; they form parallel wires. These are each formed by an electrical line 11a, 12a, for example made of copper, as well as an insulating sheath 11b, 12b surrounding the respective line.
- the wires 11, 12 of the cable 1 are arranged together in a cable jacket 15 which is defined by a cable jacket 15 running in the cable longitudinal direction L and is surrounded by the cable interior in a ring-shaped manner in cross-section.
- the cable sheath 15 consists of an electrically insulating material.
- the cable shield 14 may for example be formed by a braided screen or by a film or by a screen braid in combination with a film.
- the cable shield 14 serves to shield the cable interior and consists for this purpose of a metallic material, such as aluminum.
- a cable shield 14 in the form of a foil may be an aluminum foil.
- a plastic film can be used for this purpose, which, in particular on the inside facing the cable interior, is coated with an electrically conductive material, such as aluminum.
- Shield braids are used in particular for shielding at comparatively low frequencies and cable screens in the form of films for shielding at comparatively high frequencies (1 MHz to 10 GHz).
- FIG. 2B schematically shows a possible concrete embodiment of a cable shield 14.
- the cable shield 14 is wrapped in the form of a film around the cable inside, that the two connecting portions 141, 142 of the film overlap in the circumferential direction.
- the cable shield 14 can be selectively opened if - for example when assembling the cable - the cable interior is to be accessed.
- the cable shield 14 may be combined with the cable jacket 15 to form a structural unit, e.g. in that the cable shield 14 is connected to the cable sheath 15 on its outer surface remote from the cable interior, for example via an adhesive.
- Beilauflitzen 21, 22 are arranged, each extending together with the wires 11, 12 along the cable longitudinal direction L.
- the Beilauflitzen 21, 22 are electrically conductive and not isolated, and they are in electrical contact with the cable shield 14.
- Such Beilauflitzen 21, 22 serve to define the cable shield 14 defined to ground potential, and advantageously even if the cable shield 14 is locally damaged, is torn in sections in the case of a film.
- the battens 21, 22 can additionally contribute to the shielding of the cable interior.
- a respective Beilauflitze 21, 22 contain a magnetic, in particular a ferromagnetic material. This may be an alloy (based on iron, nickel, cobalt), in particular steel.
- a respective fillet slit 21, 22 consists entirely of an electrically conductive ferromagnetic material.
- a respective Beilauflitze 21, 22 at least one consisting of a ferromagnetic material core, which is surrounded by an electrically conductive material.
- This embodiment makes it possible to optimize, on the one hand, the core of a respective fill-strands 21, 22 with regard to the magnetic properties and the optimization of the outer conductive region of a respective fill-strands 21, 22 with regard to the electrical properties (also with regard to the skin effect at high levels) frequencies).
- a respective Beilauflitze 21, 22 may be formed approximately by a core of steel, which is coated with copper. Coating can be done by electroplating, for example.
- Both a respective core 11, 12 and a respective Beilauflitze 21, 22 of the electric cable 1 from the Figures 1A . 1B and 2A consists of a plurality of individual wires regularly.
- a (connector-side) connecting portion of the cable 1 is released from the cable sheath 15. Separating the battens 21, 22 from the wires 11, 12 of the cable, about those cable components 11, 12; 21, 22 separated from the respective associated connection points on the connector Figure 1A to be able to perform, takes place in the embodiment by the use of magnetic forces. As based on FIG. 2A recognizable, this is - after cutting the cable sheath 15 at the plug-side cable end - a respective Beilauflitze 21, 22 at the corresponding cable end a magnet M approximated.
- a respective fillet slit 21, 22 contains a material with such magnetic properties that the slits 21, 22 can be separated from the strands 11, 12 of the cable 1 under the influence of magnetic forces. That is, the magnetic properties of the fillets 21, 22 must be different from those of a respective wire 11, 12.
- a support crimp 16 is applied thereto, which may be (optionally) surrounded by a potting 18, for example in the form of a ferrite-core-filter encapsulation.
- a cable-side (ferrite core) filter acts here as a jacket wave filter, in particular for the suppression of sheath waves in the form of high-frequency common mode noise, which are caused for example by electrical equipment and propagate along the cable 1.
- the filter thus serves to eliminate or reduce common-mode noise which occurs in phase at the two parallel wires 11, 12 or the electrical leads 11a, 12a and which are caused in particular by sheath waves in the present example.
- the adjoining the plug-side end of the cable 1 connector comprises an outer conductor 8, in the embodiment in the form of an outer tube, which consists of an electrically conductive material and which surrounds the plug in cross-section annular or concrete in the exemplary embodiment annular.

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 construction of an electrical connector for multi-core electrical cables, connected to the input side, an electrical cable is and the output side is provided with electrical connector elements to bring the electrical cable via the connector and in particular its connector elements with a mating connector in electrical connection.
Zum technischen Hintergrund der Erfindung sei beispielhaft auf die
Dieses Problem wird erfindungsgemäß durch die Schaffung eines elektrischen Steckverbinders mit den Merkmalen des Anspruchs 1 gelöst.This problem is inventively solved by the provision of an electrical connector with the features of
Danach ist bei einem gattungsgemäßen elektrischen Steckverbinder weiterhin 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 mindestens zwei der kabelseitigen Kontaktelemente und mindestens zwei der ausgangsseitigen Kontaktelemente elektrisch miteinander verbunden sind, wobei das elektrische Bauelement von dem Trägerkörper gehalten wird, ohne diesen elektrisch zu kontaktieren. Dies bedeutet insbesondere, dass keines der kabelseitigen oder ausgangsseitigen Kontaktelemente über das elektrische Bauelement mit dem Trägerkörper in elektrischem Kontakt steht. Mit anderen Worten ausgedrückt, hat die (erfindungsgemäße, strukturelle) Maßnahme, dass kein elektrischer Kontakt zwischen dem elektrischen Bauelement und dem Trägerkörper besteht, die (funktionale) Folge, dass über das elektrische Bauelement weder eines der kabelseitigen noch eines ausgangsseitigen Kontaktelemente mit dem Trägerkörper in elektrischem Kontakt stehen kann.Thereafter, it is further provided in a generic electrical connector 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 hand, a support body is arranged, which carries an electrical component, on the at least two of the cable-side contact elements and at least two of Output-side contact elements are electrically connected to each other, wherein the electrical component is held by the carrier body, without contacting it electrically. This means, in particular, that none of the cable-side or output-side contact elements is in electrical contact with the carrier body via the electrical component. In other words, the (inventive, structural) measure that there is no electrical contact between the electrical component and the carrier body, the (functional) consequence that on the electrical component neither one of the cable side nor an output-side contact elements with the carrier body in can stand electrical contact.
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. Da der Trägerkörper speziell der Halterung des (mindestens einen) elektrischen Bauelementes dient, nicht aber dessen elektrischer Kontaktierung, kann dieser gezielt im Hinblick auf jene Funktion, d.h., mit Blick auf seine mechanischen Eigenschaften, optimiert werden.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 protrude its connector elements. As the carrier body especially the holder of the (at least one) electrical component is used, but not its electrical contact, this can be targeted with respect to that function, ie, with regard to its mechanical properties, optimized.
So kann der Trägerkörper gezielt zur zuverlässigen Aufnahme von Kräften, wie zum Beispiel Torsionskräften, ausgestaltet werden, und er kann als Anschlags- und Arretierungsmittel für weitere Komponenten, wie zum Beispiel für einen Außenleiter des Steckverbinders, dienen.Thus, the carrier body can be designed specifically for reliable absorption of forces, such as torsional forces, and it can serve as a stop and locking means for other components, such as for an outer conductor of the connector.
Gemäß einer Ausführungsform bildet der Trägerkörper einerseits einen Trägerbereich, der sich von einem ersten Verbindungsabschnitt zu einem zweiten Verbindungsabschnitt erstreckt und auf den das elektrische Bauelement aufgesetzt ist, wobei andererseits von jedem der beiden Verbindungsabschnitte des Trägerbereiches jeweils ein Stützabschnitt des Trägerkörpers derart abgeht, dass der Trägerbereich und die beiden Stützabschnitte eine ringförmig (z.B. bügelförmig) umlaufende Struktur bilden. Eine solche ist besonders geeignet zur Aufnahme von Torsionskräften.According to one embodiment, the carrier body forms on the one hand a carrier region, which extends from a first connecting portion to a second connecting portion and on which the electrical component is mounted, on the other hand from each of the two connecting portions of the carrier region in each case a support portion of the carrier body such that the carrier region and the two support sections form a ring-shaped (eg bow-shaped) circumferential structure. Such is particularly suitable for absorbing torsional forces.
Die beiden Stützabschnitte können dabei jeweils bogenförmig verlaufen. Weiterhin können die beiden Stützabschnitte jeweils ein (vom jeweiligen Verbindungsabschnitt des Trägerbereiches beabstandetes) freies Ende aufweisen und dabei derart geformt sein, dass die freien Enden der beiden Stützabschnitte einander zugewandt sind und einander gegenüber liegen (und dabei gegebenenfalls aneinander anliegen).The two support sections can each extend arcuately. Furthermore, the two support sections may each have a free end (spaced from the respective connection section of the support section) and be shaped in such a way that the free ends of the two support sections face each other and face each other (and possibly abut one another).
Der Trägerkörper kann einstückig geformt sein, sodass dessen Stützabschnitte durch Biegen derart positioniert worden sind, dass sie gemeinsam mit dem Trägerbereich des Trägerkörpers eine ringförmige (insbesondere bügelförmige) Kontur bilden.The carrier body may be integrally formed, so that its support portions have been positioned by bending such that they form an annular (in particular bow-shaped) contour together with the carrier region of the carrier body.
Das elektrische Bauelement, welches auf den Trägerkörper aufgesetzt ist, ohne mit diesem elektrisch kontaktiert zu sein, kann beispielsweise über Drähte einerseits mit den kabelseitigen und andererseits mit den ausgangsseitigen Kontaktelementen des Steckverbinders elektrisch leitend verbunden sein, und zwar insbesondere derart, dass über das elektrische Bauelement die kabelseitigen und die ausgangsseitigen Kontaktelemente jeweils paarweise miteinander verbunden sind.The electrical component which is placed on the carrier body, without being electrically contacted with this, for example, via wires on the one hand with the cable side and on the other hand with the output side contact elements of the connector to be electrically connected, in particular such that on the electrical component the cable-side and the output-side contact elements are each connected in pairs.
Sofern die Komponenten des Steckverbinders, wie die kabelseitigen und ausgangsseitigen Kontaktelemente sowie der Trägerkörper von einem Außenleiter (z.B. einem elektrisch leitfähigen Außenrohr) umschlossen werden, kann der Trägerkörper mit dem Außenleiter verbunden sein, insbesondere formschlüssig und/oder stoffschlüssig.If the components of the connector, such as the cable-side and output-side contact elements and the carrier body by an outer conductor (eg an electrically conductive outer tube) are enclosed, the carrier body may be connected to the outer conductor, in particular form-fitting and / or material fit.
Der Trägerkörper ist dabei teilweise innerhalb des von dem Außenleiter umgebenen Raumes angeordnet, und zwar insbesondere derart, dass auch das vom Trägerkörper gehaltene elektrische Bauelement innerhalb des vom Außenleiter umgebenen Raumes liegt. Gleichzeitig kann der Trägerkörper abschnittsweise aus dem Außenleiter herausgeführt sein, zum Beispiel durch Schlitze des Außenleiters hindurch.The carrier body is partially disposed within the space surrounded by the outer conductor, in particular such that also held by the carrier body electrical component is within the space surrounded by the outer conductor. At the same time, the carrier body may be led out in sections from the outer conductor, for example through slots of the outer conductor.
Konkret kann der Trägerkörper derart angeordnet sein, dass dessen Trägerbereich zusammen mit dem hieran gehaltenen elektrischen Bauelement innerhalb des von dem Außenleiter umschlossenen Raumes liegt und dass der Trägerbereich an seinen Verbindungsabschnitten aus dem Außenleiter herausgeführt ist. Dabei können die Stützabschnitte des Trägerkörpers den Außenleiter außenseitig abschnittsweise umschließen.Concretely, the carrier body may be arranged such that its carrier region is located together with the electric component held thereon within the space enclosed by the outer conductor and that the carrier region is guided out of the outer conductor at its connecting portions. In this case, the support sections of the carrier body can enclose the outer conductor sections on the outside.
Die Stützabschnitte des Trägerkörpers werden vorteilhaft erst umgebogen, nachdem der Trägerkörper mit seinem Trägerbereich und dem darauf aufgesetzten elektrischen Bauelement innerhalb des vom Außenleiter umschlossenen Raumes angeordnet worden ist und die Stützabschnitte des Trägerkörpers aus dem Außenleiter ausgeführt worden sind, zum Beispiel durch Schlitze des Außenleiters hindurch.The support sections of the carrier body are advantageously bent over only after the carrier body has been arranged with its carrier region and the electrical component mounted thereon within the space enclosed by the outer conductor and the support sections of the carrier body have been made of the outer conductor, for example through slots of the outer conductor.
Gemäß einer Weiterbildung der Erfindung sind die eingangsseitigen (kabelseitigen) sowie die ausgangsseitigen elektrischen Kontaktelemente und weiterhin der Trägerkörper für das elektrische Bauelement als Bestandteile eines einzelnen, einstückig geformten Bauteiles, zum Beispiel in Form eines Stanzgitters, hergestellt und in den Steckverbinder integriert worden. Anschließend wird das Stanzgitter in die separaten Komponenten "eingangsseitige (kabelseitige) elektrische Kontaktelemente", "ausgangsseitige elektrische Kontaktelemente" und "Trägerkörper" separiert, sodass die einzelnen kabelseitigen Kontaktelemente und die ausgangsseitigen Kontaktelemente sowie der Trägerkörper als separate Komponenten vorliegen, die (elektrisch) nicht miteinander verbunden sind.According to one embodiment of the invention, the input side (cable side) and the output side electrical contact elements and further the support body for the electrical component as components of a single, integrally molded component, for example in the form of a stamped grid, manufactured and integrated into the connector. Subsequently, the lead frame is separated into the separate components "input side (cable side) electrical contact elements", "output side electrical contact elements" and "carrier body", so that the individual cable-side contact elements and the output-side contact elements and the carrier body are present as separate components, not (electrically) connected to each other.

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
Zwischen dem zur Aufnahme der Adern 11, 12 dienenden Kabelinneren und dem Kabelmantel 15 ist weiterhin ein (in den
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 screens in the form of films 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 one variant, a respective fillet slit 21, 22 consists entirely of an electrically conductive ferromagnetic material. According to another 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 method described that a respective fillet slit 21, 22 contains a material with such magnetic properties that the

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.At 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 adjoining the plug-side 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 spaced 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.Between the cable-
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.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.Of the connecting
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 region 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 outgoing of the connecting
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 (as a result of 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.Other 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.On the

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 stamped grid are separated (for example by provided on the
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 singling of the said components 30-34, 4, 71-74 can take place, for example, by means of severing those components on the stamped grid of connecting webs which are still initially connected.
