Definitions
- the invention relates to a plug or a coupler, designed for connection to a coaxial line according to the features of the preamble of claim 1.
- plugs or couplers for connection to coaxial lines over which high-frequency signals are transmitted are known in principle.
- the coaxial line itself has an inner conductor (signal line) which is surrounded by insulation, on which in turn a shield (for example in the form of a shielding braid) is arranged.
- This shield is surrounded by an outer jacket of the coaxial line.
- Plugs or couplers have a réelleleiter ⁇ element which is connected to the signal line, and an outer conductor element, which is connected to the shield of the coaxial line.
- the inner conductor element is located coaxially within the outer conductor element, wherein an insulating support body (for example made of plastic) is arranged between these two elements.
- This entire arrangement of inner conductor and outer conductor element and support body is usually surrounded by an outer housing made of an electrically non-conductive material.
- Inner conductor and outer conductor element have a connection region and a contact region, wherein the coaxial line in the connection region of the inner conductor or outer conductor element is connected in a suitable form.
- the contact area is designed as a plug contact for the plug and as a socket contact for the coupler, so that the finished plug can be plugged together with the finished coupler to form an entire plug connection.
- the inner conductor element usually also the outer conductor element, is turned out of a solid material.
- these elements are produced as a turned part, which on the one hand requires a long machining time and is disadvantageous in terms of cost, since these parts have to be turned from solid material. This disadvantage is especially great when these items are mass-produced.
- Another disadvantage may also be the dimensions of the inner conductor or the outer conductor element. Especially in the application of plugs or couplers in automobiles, it is necessary to make these parts very small, so compact and space-saving. Because of space reasons, these parts must be compact and can be built, as this high-frequency signals are transmitted and no high currents that would make larger elements required.
- a requirement is therefore a miniaturization, which requires that, for example, the outer diameter of the inner conductor element is below 5 mm.
- the required geometric design of an inner conductor element with contact area, connection area and intermediate part is either not possible at all by means of a turning process, or only with a further increased disadvantage.
- the invention is therefore based on the object to provide a plug or a coupler with a réelleleiter- and a stratieiterelement that is inexpensive and fast to produce as a commodity and when used in vehicles offers the required compactness.
- the existing of an electrically conductive material inner conductor element from a flat sheet metal strip can be brought by a plastic deformation in its final form.
- This plastic deformation may include a rolling operation when the inner conductor element has a round shape.
- the plastic deformation is a stamped bending process with which the required compression, embossing, stop and locking elements can be produced in one or more work steps.
- This punch bending process has the particular advantage that it is suitable for the mass production of such elements and thus also the required geometries, in particular the smallest parts with a diameter below about 10 mm, preferably below 5 mm in diameter to produce.
- the inner conductor element produced according to the invention thus has the advantage that it is cheaper to manufacture compared to rotary parts, both manually and automatically mounted and is also easy to service in terms of interchangeability in case of damage to the plug or coupler.
- the changing in its course cross-section of the Crimpinatel (in particular the Aufdopp ⁇ development) has the advantage that the usual for use in the vehicle area cable types of coaxial cables can be posted. This results in significant cost savings compared to a formed as a rotating part inner conductor element with identical or even increased quality.
- stop edges and locking means are specified in the dependent claims, said stop edges and locking means of positional positioning of the inner conductor element within the insulating support body and its defined fixing (locking) relate.
- the inner conductor element has a crimping region formed in the stamping bending process and the crimping region a support region for the signal line as well as mutually parallel and deformable Crimperiel having a changing in their course cross-sectional shape.
- the cross-sectional shape that changes in its course has the advantage that the known and well-functioning crimping process for the gas-tight fixing of the electrical conductor to the crimping area is maintained, but at the same time any cross-sectional shapes or diameters of signal lines can be used.
- the cross-sectional shape that changes in its course thus ensures that the crimping region, after the crimping process has been carried out, is still closed gas-tight, independently of the diameter of the signal line used there. Furthermore, it is conceivable that the course of the cross-sectional shape of the Crimperiel changes abruptly and / or continuously. It is also conceivable that the thickness of the support area and the thickness of the Crimpulatel change abruptly and / or continuously in the transition region, just as the thickness of the Crimperiel and the thickness of its end can change abruptly and / or continuously.

- Figures 3 and 4 an inner conductor element of a coupler within the insulating support body and shown alone.
- Figure 1 shows, as far as shown in detail, at least partially a plug 1, which has an insulating support body 2 made of a plastic material.
- This support body 2 can be produced in a plastic injection molding process.
- the support body 2 is designed for coaxial reception of an inner conductor element 3, which can be brought into its final shape, as shown in FIG. 1, by means of a plastic deformation.
- the inner conductor element 3 has a contact pin 4, which can be brought into operative connection with a socket, not shown here, when plug and coupler are plugged together.
- a crimping region 5 is present, at which the signal line of the coaxial line, not shown here, is struck.
- a connecting part 6 is provided, which has a stop edge 7.
- the movement is stopped in the introduction of the inner conductor element 3 in the support body 2, so that in particular in an automatic assembly, the inner conductor element 3 receives a defined position within the support body 2.
- the support body 2 has a receiving area 8 for a socket element to be used here.
- this has an insertion funnel 9 on the end facing away from the receiving region 8.
- the reference numeral 10 locking means of the inner conductor element 3 are referred to, for example, formed as resilient protruding tabs are, which are also produced in the punch bending process. These locking means 10 engage in a corresponding shape within the supporting body 2.
- FIG. 2 shows the inner conductor element 3 on its own, before it is inserted into the supporting body 2 and after it has been produced in the stamping bending process.
- crimp wings 12 extend and, in the illustrated open state, have an approximately U-shaped cross-section. Inside, several individual strands can be inserted and crimped gas-tight, if the signal line is a stranded conductor. However, an electric round conductor can just as well be used here.

- the support body 15 of the coupler 14, as well as the support body 2 of the plug 1, may have a projection 24 and / or a constriction 25, which allow the support body 2, 15 coaxially within the not here dargestell ⁇ th outer conductor element of the plug. 1 or the coupler 14 can be fixed.

Stecker oder Kuppler mit einem im Stanzbiegeverfahren hergestellten InnenleiterelementPlug or coupler with an inner conductor element produced by punch bending
Technisches GebietTechnical area
Die Erfindung betrifft einen Stecker oder einen Kuppler, ausgebildet zum Anschluss an eine Koaxialleitung gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a plug or a coupler, designed for connection to a coaxial line according to the features of the preamble of claim 1.
Stand der TechnikState of the art
Solche Stecker oder Kuppler zum Anschluss an Koaxialleitungen, über die hochfrequente Signale übertragen werden, sind grundsätzlich bekannt. Die Koaxialleitung selber weist einen Innenleiter (Signalleitung) auf, die von einer Isolierung umgeben ist, auf der wiederum eine Abschirmung (z.B. in Form eines Abschirmgeflechtes) angeordnet ist. Diese Abschirmung ist von einem Außen¬ mantel der Koaxialleitung umgeben. Stecker oder Kuppler weisen ein Innenleiter¬ element auf, das an der Signalleitung angeschlossen wird, sowie ein Außenleiter- element, welches an der Abschirmung der Koaxialleitung angeschlossen wird. Dabei befindet sich das Innenleiterelement koaxial innerhalb des Außenleiterele- mentes, wobei zwischen diesen beiden Elementen ein isolierender Tragkörper (z.B. aus Kunststoff) angeordnet ist. Diese gesamte Anordnung aus Innenleiter- und Außenleiterelement sowie Tragkörper wird im Regelfall noch von einem Außengehäuse aus einem elektrisch nicht leitfähigen Material umgeben.Such plugs or couplers for connection to coaxial lines over which high-frequency signals are transmitted are known in principle. The coaxial line itself has an inner conductor (signal line) which is surrounded by insulation, on which in turn a shield (for example in the form of a shielding braid) is arranged. This shield is surrounded by an outer jacket of the coaxial line. Plugs or couplers have a Innenleiter¬ element which is connected to the signal line, and an outer conductor element, which is connected to the shield of the coaxial line. In this case, the inner conductor element is located coaxially within the outer conductor element, wherein an insulating support body (for example made of plastic) is arranged between these two elements. This entire arrangement of inner conductor and outer conductor element and support body is usually surrounded by an outer housing made of an electrically non-conductive material.
Innenleiter- und Außenleiterelement weisen einen Anschlussbereich und einen Kontaktbereich auf, wobei die Koaxialleitung im Anschlussbereich des Innenleiter- bzw. Außenleiterelementes in geeigneter Form angeschlossen wird. Der Kontaktbereich ist beim Stecker als Steckkontakt und beim Kuppler als Buchsen¬ kontakt ausgebildet, so dass der fertige Stecker mit dem fertigen Kuppler zu einer gesamten Steckverbindung zusammengesteckt werden kann.Inner conductor and outer conductor element have a connection region and a contact region, wherein the coaxial line in the connection region of the inner conductor or outer conductor element is connected in a suitable form. The contact area is designed as a plug contact for the plug and as a socket contact for the coupler, so that the finished plug can be plugged together with the finished coupler to form an entire plug connection.
Es ist bekannt, dass das Innenleiterelement, meistens auch das Außenleiterele- ment, aus einem Vollmaterial herausgedreht wird. Das bedeutet, dass diese Elemente als Drehteil hergestellt werden, was zum einen eine lange Bearbei¬ tungszeit erforderlich macht und kostennachteilig ist, da diese Teile aus Vollmate¬ rial gedreht werden müssen. Dieser Nachteil ist gerade dann besonders groß, wenn diese Elemente als Massenware hergestellt werden. Ein weiterer Nachteil können auch die Dimensionen des Innenleiter- oder des Außenleiterelementes sein. Gerade bei der Anwendung von Steckern oder Kupplern in Automobilen ist es erforderlich, diese Teile besonders klein, damit kompakt und Platz sparend auszugestalten. Denn aus Platzgründen müssen diese Teile kompakt gebaut sein und können es auch, da hierüber hochfrequente Signale übertragen werden und keine hohen Ströme, die größere Elemente erforderlich machen würden. Ein Erfordernis ist daher eine Miniaturisierung, die fordert, dass beispielsweise der Außendurchmesser des Innenleiterelementes unterhalb von 5 mm liegt. Die erforderliche geometrische Gestaltung eines Innenleiterelementes mit Kontaktbe¬ reich, Anschlussbereich und Zwischenteil ist mittels eines Drehvorganges entweder überhaupt nicht möglich, oder nur mit einem weiter gesteigerten Nachteil.It is known that the inner conductor element, usually also the outer conductor element, is turned out of a solid material. This means that these elements are produced as a turned part, which on the one hand requires a long machining time and is disadvantageous in terms of cost, since these parts have to be turned from solid material. This disadvantage is especially great when these items are mass-produced. Another disadvantage may also be the dimensions of the inner conductor or the outer conductor element. Especially in the application of plugs or couplers in automobiles, it is necessary to make these parts very small, so compact and space-saving. Because of space reasons, these parts must be compact and can be built, as this high-frequency signals are transmitted and no high currents that would make larger elements required. A requirement is therefore a miniaturization, which requires that, for example, the outer diameter of the inner conductor element is below 5 mm. The required geometric design of an inner conductor element with contact area, connection area and intermediate part is either not possible at all by means of a turning process, or only with a further increased disadvantage.
Darstellung der ErfindungPresentation of the invention
" Der Erfindung liegt daher die Aufgabe zu Grunde, einen Stecker oder einen Kuppler mit einem Innenleiter- und einem Außenieiterelement bereitzustellen, der als Massenware kostengünstig und schnell herstellbar ist und bei der Anwendung bei Fahrzeugen die erforderliche Kompaktheit bietet. " The invention is therefore based on the object to provide a plug or a coupler with a Innenleiter- and a Außenieiterelement that is inexpensive and fast to produce as a commodity and when used in vehicles offers the required compactness.
Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass das aus einem elektrisch leitfähigen Material bestehende Innenleiterelement aus einem flachen Blechstreifen durch eine plastische Verformung in seine endgültige Form bringbar ist. Diese plastische Verformung kann einen Rollvorgang umfassen, wenn das Innenleiterelement eine runde Form aufweist. Im Regelfall bietet es sich an, dass die plastische Verfor¬ mung ein Stanzbiegeverfahren ist, mit dem die erforderlichen Stauchungen, Prägungen, Anschlag- und Rastelemente in einem oder mehreren Arbeitsschritten herstellbar sind. Dieses Stanzbiegeverfahren hat den besonderen Vorteil, dass es sich für die Massenherstellung von solchen Elementen eignet und damit auch die erforderlichen Geometrien, insbesondere kleinste Teile mit einem Durchmesser unterhalb von etwa 10 mm, vorzugsweise unterhalb von 5 mm Durchmesser, herzustellen.This object is solved by the features of claim 1. According to the invention it is provided that the existing of an electrically conductive material inner conductor element from a flat sheet metal strip can be brought by a plastic deformation in its final form. This plastic deformation may include a rolling operation when the inner conductor element has a round shape. As a rule, it makes sense that the plastic deformation is a stamped bending process with which the required compression, embossing, stop and locking elements can be produced in one or more work steps. This punch bending process has the particular advantage that it is suitable for the mass production of such elements and thus also the required geometries, in particular the smallest parts with a diameter below about 10 mm, preferably below 5 mm in diameter to produce.
Das erfindungsgemäß hergestellte Innenleiterelement hat also den Vorteil, dass es kostengünstiger gegenüber Drehteilen herstellbar ist, sowohl manuell als auch automatisch montierbar ist und dazu auch servicefreundlich in Bezug auf die Austauschbarkeit bei Beschädigung des Steckers oder des Kupplers ist.The inner conductor element produced according to the invention thus has the advantage that it is cheaper to manufacture compared to rotary parts, both manually and automatically mounted and is also easy to service in terms of interchangeability in case of damage to the plug or coupler.
Außerdem bietet in einer weiteren Ausgestaltung der Erfindung der in seinem Verlauf sich ändernde Querschnitt der Crimpflügel (insbesondere die Aufdopp¬ lung) den Vorteil, dass die bei Anwendung im Fahrzeugbereich gebräuchlichen Kabeltypen von Koaxialleitungen angeschlagen werden können. Daraus ergeben sich deutliche Kosteneinsparungen gegenüber einem als Drehteil ausgebildeten Innenleiterelement bei identischer oder sogar gesteigerter Qualität.In addition, in a further embodiment of the invention, the changing in its course cross-section of the Crimpflügel (in particular the Aufdopp¬ development) has the advantage that the usual for use in the vehicle area cable types of coaxial cables can be posted. This results in significant cost savings compared to a formed as a rotating part inner conductor element with identical or even increased quality.
Weitere Ausgestaltungen der Erfindungen, insbesondere Anschlagkanten sowie Rastmittel, sind in den Unteransprüchen angegeben, wobei diese Anschlagkanten sowie Rastmittel der Lagepositionierung des Innenleiterelementes innerhalb des isolierenden Tragkörpers und seiner definierten Festlegung (Verriegelung) betreffen.Further embodiments of the invention, in particular stop edges and locking means are specified in the dependent claims, said stop edges and locking means of positional positioning of the inner conductor element within the insulating support body and its defined fixing (locking) relate.
In Weiterbildung der Erfindung ist vorgesehen, dass Innenleiterelement einen im Stanzbiegeverfahren geformten Crimpbereich aufweist und der Crimpbereich einen Auflagebereich für die Signalleitung sowie parallel zueinander verlaufende und verformbare Crimpflügel aufweist, die einen sich in ihrem Verlauf ändernde Querschnittsform aufweisen. Die sich in ihrem Verlauf ändernde Querschnittsform hat den Vorteil, dass dadurch der an sich bekannte und gut funktionierende Crimpvorgang zum gasdichten Festlegen des elektrischen Leiters an dem Crimpbereich beibehalten wird, gleichzeitig aber auch beliebige Querschnittsfor¬ men bzw. Durchmesser von Signalleitungen eingesetzt werden können. Denn bisher war es erforderlich, den Crimpbereich eines Innenleiterelementes in seinen geometrischen Abmessungen auf die jeweils verwendete Signalleitung abzustim¬ men, so dass unterschiedliche Durchmesser bzw. Querschnittsformen der Signalleitungen auch unterschiedliche Geometrien des Crimpbereichs des Innenleiterelementes zur Folge hatten. Diese Teilevielfalt wird nun in der erfindungsgemäßen Weise dadurch reduziert, dass der Crimpbereich, genauer dessen Crimpflügel, einen sich in ihrem Verlauf ändernde Querschnittsform aufweisen. Dadurch können sich die Crimpflügel dem jeweils eingesetzten Ende der Signalleitung anpassen, was bei bisher bekannten Innenleiterelementen nicht der Fall war, da hier der Auflagebereich für die Signalleitung und die sich daran anschließenden Crimpflügel immer den gleichen Querschnitt bzw. die gleiche Dicke aufweisen. Die sich in ihrem Verlauf ändernde Querschnittsform gewährleis¬ tet also, dass der Crimpbereich nach Ausführung des Crimpvorganges unabhän¬ gig von dem Durchmesser der dort eingesetzten Signalleitung nach wie vor gasdicht verschlossen wird. Weiterhin ist denkbar, dass sich der Verlauf der Querschnittsform der Crimpflügel sprunghaft und/oder kontinuierlich ändert. Ebenso ist es denkbar, dass sich die Dicke des Auflagebereiches und die Dicke der Crimpflügel im Übergangsbereich sprunghaft und/oder kontinuierlich ändern, genauso wie sich die Dicke der Crimpflügel und die Dicke ihres Endbereiches sprunghaft und/oder kontinuierlich ändern können.In a further development of the invention, it is provided that the inner conductor element has a crimping region formed in the stamping bending process and the crimping region a support region for the signal line as well as mutually parallel and deformable Crimpflügel having a changing in their course cross-sectional shape. The cross-sectional shape that changes in its course has the advantage that the known and well-functioning crimping process for the gas-tight fixing of the electrical conductor to the crimping area is maintained, but at the same time any cross-sectional shapes or diameters of signal lines can be used. Until now, it was necessary to balance the crimping area of an inner conductor element in its geometrical dimensions with the signal line used in each case, so that different diameters or cross-sectional shapes of the signal lines also resulted in different geometries of the crimping area of the inner conductor element. This variety of parts is now reduced in the manner according to the invention in that the crimping region, or more precisely its crimping blade, has a cross-sectional shape which changes in its course. As a result, the Crimpflügel can adapt to the particular end of the signal line used, which was not the case with previously known inner conductor elements, since here the support area for the signal line and the adjoining Crimpflügel always have the same cross-section or the same thickness. The cross-sectional shape that changes in its course thus ensures that the crimping region, after the crimping process has been carried out, is still closed gas-tight, independently of the diameter of the signal line used there. Furthermore, it is conceivable that the course of the cross-sectional shape of the Crimpflügel changes abruptly and / or continuously. It is also conceivable that the thickness of the support area and the thickness of the Crimpflügel change abruptly and / or continuously in the transition region, just as the thickness of the Crimpflügel and the thickness of its end can change abruptly and / or continuously.

Figur 1 zeigt, soweit im Einzelnen dargestellt, zumindest teilweise einen Stecker 1 , der einen isolierenden Tragkörper 2 aus einem Kunststoffmaterial aufweist. Dieser Tragkörper 2 kann in einem Kunststoffspritzgussverfahren hergestellt werden. Der Tragkörper 2 ist ausgebildet zur koaxialen Aufnahme eines Innenleiterelementes 3, das mittels einer plastischen Verformung in seine endgültige Form, wie sie in Figur 1 gezeigt ist, bringbar ist. Das Innenleiterelement 3 weist einen Kontaktstift 4 auf, der in Wirkverbindung mit einer hier nicht dargestellten Buchse bringbar ist, wenn Stecker und Kuppler zusammengesteckt werden.

Mittels dieser Anschlagkante 7 wird die Bewegung bei der Einführung des Innenleiterelementes 3 in den Tragkörper 2 gestoppt, so dass insbesondere bei einer automatischen Montage das Innenleiterelement 3 eine definierte Lage innerhalb des Tragkörpers 2 aufnimmt. Der Tragkörper 2 weist einen Aufnahmebereich 8 für ein hier einzusetzendes Buchsenelement auf. Zur vereinfachten Einführung des Innenleiterelementes 3 in den Tragkörper 2 weist dieser auf der dem Aufnahmebereich 8 abgewandten Ende einen Einführungs¬ trichter 9 auf. Mit der Bezugsziffer 10 sind Rastmittel des Innenleiterelementes 3 bezeichnet, die beispielsweise als federnde abstehende Laschen ausgebildet sind, die ebenfalls im Stanzbiegeverfahren herstellbar sind. Diese Rastmittel 10 greifen in eine entsprechende Form innerhalb des Tragkörpers 2 ein.Figure 1 shows, as far as shown in detail, at least partially a plug 1, which has an insulating support body 2 made of a plastic material. This support body 2 can be produced in a plastic injection molding process. The support body 2 is designed for coaxial reception of an inner conductor element 3, which can be brought into its final shape, as shown in FIG. 1, by means of a plastic deformation. The inner conductor element 3 has a contact pin 4, which can be brought into operative connection with a socket, not shown here, when plug and coupler are plugged together. On the side facing away from the contact pin 4, a crimping region 5 is present, at which the signal line of the coaxial line, not shown here, is struck. Between contact pin 4 and crimping area 5, a connecting part 6 is provided, which has a stop edge 7. By means of this stop edge 7, the movement is stopped in the introduction of the inner conductor element 3 in the support body 2, so that in particular in an automatic assembly, the inner conductor element 3 receives a defined position within the support body 2. The support body 2 has a receiving area 8 for a socket element to be used here. For simplified introduction of the inner conductor element 3 into the support body 2, this has an insertion funnel 9 on the end facing away from the receiving region 8. The reference numeral 10 locking means of the inner conductor element 3 are referred to, for example, formed as resilient protruding tabs are, which are also produced in the punch bending process. These locking means 10 engage in a corresponding shape within the supporting body 2.
Figur 2 zeigt das Innenleiterelement 3 alleine, bevor es in den Tragkörper 2 eingesetzt wird und nachdem es im Stanzbiegeverfahren hergestellt worden ist. In Figur 2 ist erkennbar, dass sich ausgehend von einem Auflagebereich 11 Crimpflügel 12 erstrecken und im dargestellten offenen Zustand eine in etwa U- Querschnittsform aufweisen. Im Inneren können mehrere Einzellitzen eingelegt und gasdicht vercrimpt werden, wenn es sich bei der Signalleitung um einen Litzenleiter handelt. Genauso gut kann hier aber auch ein elektrischer Rundleiter eingesetzt werden. Durch das Stanzbiegeverfahren mit anschließendem Rollvorgang entsteht ein Schlitz 13, der offen bleiben kann oder auch verschlie߬ bar ist (zum Beispiel durch einen Löt- oder Schweißvorgang entlang des Schlitzes 13).FIG. 2 shows the inner conductor element 3 on its own, before it is inserted into the supporting body 2 and after it has been produced in the stamping bending process. In FIG. 2, it can be seen that, starting from a support region 11, crimp wings 12 extend and, in the illustrated open state, have an approximately U-shaped cross-section. Inside, several individual strands can be inserted and crimped gas-tight, if the signal line is a stranded conductor. However, an electric round conductor can just as well be used here. The punch bending process with subsequent rolling operation produces a slot 13 which can remain open or is also closable (for example by a soldering or welding process along the slot 13).
Figur 3 zeigt, analog zu dem Stecker 1 der Figur 1 , einen zugehörigen Kuppler 14, der hier ebenfalls nur teilweise dargestellt ist. Der Kuppler 14 weist ebenfalls einen Tragkörper 15 zur Aufnahme eines Innenleiterelementes 16 auf. Im Steckbereich hat das Innenleiterelement 16 eine Buchse, insbesondere eine federnde Buchse 17, die in Wirkverbindung mit dem Kontaktstift 4 des Steckers 1 bringbar ist. Auf der gegenüberliegenden Seite ist ebenfalls ein Crimpbereich 18 und dazwischen ein Verbindungsteil 19 vorhanden. Auch das Innenleiterelement 16 weist zur definierten Positionierung innerhalb des Tragkörpers 15 eine Anschlagkante 20 auf. Der Tragkörper 15 ist mit einem Aufnahmebereich 21 zur Aufnahme des Kontaktstiftes 4 und auf der gegenüberliegenden Seite mit einem Einführungstrichter 22 versehen, um das Einführen des Innenleiterelementes 16 in den Tragkörper 15 zu erleichtern. Verriegelt wird das Innenleiterelement 16 innerhalb des Tragkörpers 15 mit Rastmitteln 23, analog zu den Rastmitteln 10 bei dem Stecker 1. An dieser Stelle sei erwähnt, dass die Anschlagkanten 7, 20 und/oder die Rastmittel 10, 23 auch andersartig, z.B. an einer anderen Stelle, vorhanden sein können, oder auch ganz entfallen können, wenn z.B. durch die automatische Montage sichergestellt ist, dass das Innenleiterelement 3, 16 in einer definierten Position in seinem zugehörigen Tragkörper 2, 15, festlegbar ist und dort dauerhaft verriegelt wird. Anstelle von Rastmitteln für die Verriegelung kommen beispielsweise auch Verschraubungen, Verklebungen oder dergleichen in Frage.Figure 3 shows, analogous to the plug 1 of Figure 1, an associated coupler 14, which is also shown only partially here. The coupler 14 also has a support body 15 for receiving an inner conductor element 16. In the mating area, the inner conductor element 16 has a socket, in particular a resilient bushing 17, which can be brought into operative connection with the contact pin 4 of the plug 1. On the opposite side is also a crimping area 18 and between a connecting part 19 is present. Also, the inner conductor element 16 has a stop edge 20 for defined positioning within the support body 15. The support body 15 is provided with a receiving portion 21 for receiving the contact pin 4 and on the opposite side with an insertion funnel 22 to facilitate the insertion of the inner conductor element 16 in the support body 15. The inner conductor element 16 is locked within the support body 15 with locking means 23, analogous to the locking means 10 in the connector 1. At this point it should be noted that the stop edges 7, 20 and / or the locking means 10, 23 also different, eg to another Place, may be present, or may be omitted completely, if, for example, by the automatic assembly ensures that the inner conductor element 3, 16 in a defined position in its associated support body 2, 15, can be fixed and is locked there permanently. Instead of locking means for the locking, for example, also glands, bonds or the like in question.
Der Tragkörper 15 des Kupplers 14, genauso wie der Tragkörper 2 des Steckers 1 , kann einen Vorsprung 24 und/oder eine Einschnürung 25 aufweisen, die es ermöglichen, dass der Tragkörper 2, 15 koaxial innerhalb des hier nicht dargestell¬ ten Außenleiterelementes des Steckers 1 oder des Kupplers 14 festlegbar ist.The support body 15 of the coupler 14, as well as the support body 2 of the plug 1, may have a projection 24 and / or a constriction 25, which allow the support body 2, 15 coaxially within the not here dargestell¬ th outer conductor element of the plug. 1 or the coupler 14 can be fixed.
Figur 4 zeigt das Innenleiterelement 16 des Kupplers 14 alleine, bevor es in den Tragkörper 2 eingesetzt wird und nachdem es im Stanzbiegeverfahren hergestellt und einem Rollvorgang unterzogen worden ist. In Figur 4 ist erkennbar, dass sich ausgehend von einem Auflagebereich 26 Crimpflügel 27 mit eine vorzugsweise trapezfärmigen Endbereich 29 erstrecken und im dargestellten offenen Zustand eine in etwa U-Querschnittsform aufweisen. Im Inneren können mehrere Einzellitzen eingelegt und gasdicht vercrimpt werden, wenn es sich bei der Signalleitung um einen Litzenleiter handelt. Genauso gut kann hier aber auch ein elektrischer Rundleiter eingesetzt werden. Durch das Stanzbiegeverfahren mit anschließendem Rollvorgang entsteht ein Schlitz 28, der offen bleiben kann oder auch verschließbar ist (zum Beispiel durch einen Löt- oder Schweißvorgang entlang des Schitzes 28). Die Crimpflügel 27 haben einen vorzugsweise trapez¬ förmigen Endbereich 29, können aber auch anders geformt sein.FIG. 4 shows the inner conductor element 16 of the coupler 14 alone before it is inserted into the support body 2 and after it has been produced by stamping and subjected to a rolling process. In FIG. 4, it can be seen that, starting from a support region 26, crimp wings 27 extend with a preferably trapezoidal-shaped end region 29 and in the illustrated open state have an approximately U-cross-sectional shape. Inside, several individual strands can be inserted and crimped gas-tight, if the signal line is a stranded conductor. However, an electric round conductor can just as well be used here. The stamping bending process followed by rolling produces a slot 28 which can remain open or can also be closed (for example by a soldering or welding process along the slot 28). The Crimpflügel 27 have a preferably trapezoidal end portion 29, but may also be shaped differently.
Insgesamt bietet die sich in ihrem Verlauf ändernde Querschnittsform der Crimpflügel 12, 27 also den Vorteil, dass Signalleitungen mit beliebiger Dicke in ein und dasselbe Innenleiterelement 3, 16 festlegbar und vercrimpbar sind. Die Materialverdickung (insbesondere eine Aufdoppelung der Dicke) der Crimpflügel 12, 27 bewirkt also, dass unabhängig von dem Querschnitt bzw. dem Durchmes¬ ser der eingesetzten Signalleitung der Crimpvorgang gasdicht ausgeführt werden kann. Dabei versteht es sich von selbst, dass auf Grund der geometrischen Abmessung der Innenleiterelemente 3, 16 und vor allen Dingen dessen Crimpbe- reiche 5, 18 und die Querschnitte der dort eingesetzten Signalleitungen aufeinan¬ der abgestimmt werden müssen, dies aber im Gegensatz zu bisher bekannten Innenleiterelementen mit Crimpbereich in einem sehr viel weiteren Bereich erfolgen kann. Overall, the changing in their course cross-sectional shape of the Crimpflügel 12, 27 thus offers the advantage that signal lines of any thickness in one and the same inner conductor element 3, 16 can be fixed and crimped. The thickening of the material (in particular a doubling of the thickness) of the crimping blades 12, 27 thus causes the crimping process to be carried out in a gastight manner, independently of the cross section or the diameter of the signal line used. It goes without saying that due to the geometrical dimension of the inner conductor elements 3, 16 and, above all, its crimping areas 5, 18 and the cross sections of the signal lines used there must be matched to one another, but in contrast to previously known Inner conductor elements with crimping can be done in a much wider range.
