Description

Beschreibungdescription
HF-Steckverbinder mit versetzten SchneidenHF connectors with offset cutting edges
Die vorliegende Erfindung betrifft einen Steckverbinder für HF-Leitungen nach dem Oberbegriff des Anspruchs 1.The present invention relates to a connector for HF lines according to the preamble of claim 1.
Steckverbinder nach der Art einer Schneidklemmverbindung, die über Schneiden mit einem Leiter Kontakt herstellen, um bei- spielsweise ein Signal von dem Leiter abzunehmen, oder aber um zwei Leiter über eine solche Steckverbindung mit einander zu verbinden, sind bekannt. Solche bekannten Steckverbinder werden überall dort eingesetzt, wo es erforderlich ist, eine kostengünstige Lösung zu schaffen, um eine elektrisch leiten- de Verbindung zwischen dem Steckverbinder und dem Leiter herzustellen.Connectors of the type of an insulation displacement connection which make contact with a conductor via cutting, for example to take a signal from the conductor, or to connect two conductors to one another via such a plug connection, are known. Such known connectors are used wherever it is necessary to create an inexpensive solution to establish an electrically conductive connection between the connector and the conductor.
Bei einer solchen Steckverbindung wird ganz allgemein über Schneiden aus Metall die Abschirmung der Leitung durchdrun- gen, bis die Schneiden mit dem Leiter in Kontakt kommen. Auf diese Weise läßt sich beispielsweise eine elektrisch leitende Verbindung zwischen zwei Leitungen herstellen, deren Abschirmungen von den Schneiden der Steckverbindung durchdrungen werden, so daß die beiden Leiter über die Schneiden in elek- trischem Kontakt stehen.In the case of such a plug-in connection, the shielding of the line is generally penetrated via metal cutting edges until the cutting edges come into contact with the conductor. In this way, for example, an electrically conductive connection can be established between two lines, the shields of which are penetrated by the cutting edges of the plug connection, so that the two conductors are in electrical contact via the cutting edges.
Solche Steckverbinder mit Schneidklemmtechnik haben sich bereits bewährt, da sie kostengünstig hergestellt werden können, schnell mit einem Leiter kontaktiert werden können und zudem in der Regel einen guten elektrischen Kontakt erzeugen.Such connectors with insulation displacement technology have already proven themselves because they can be manufactured inexpensively, can be contacted quickly with a conductor and, moreover, generally produce good electrical contact.
Es ist auch bereits ein Steckverbinder für HF-Leitungen bekannt geworden, bei dem ein Schneidenpaar so angeordnet ist, daß sich die Stirnflächen der beiden Schneiden genau gegen- über stehen, sich das Schneidenpaar also bezüglich der HF- Leitung in einer Ebene angeordnet befindet. Solche HF- Leitungen werden dort eingesetzt, wo große Mengen an Daten oder Signalen zu übertragen sind, die zu entsprechend hohenA connector for HF lines has also become known in which a pair of cutting edges is arranged such that the end faces of the two cutting edges are exactly opposite one another, that is to say the pair of cutting edges is arranged in one plane with respect to the HF line. Such RF lines are used where there is a large amount of data or signals to be transmitted that are of a correspondingly high level
Frequenzen auf dem Leiter führen.Lead frequencies on the conductor.
Ein Anwendungsgebiet für solche HF-Leitungen ist auch die Au- tomobiltechnik, bei der für Audiosysteme, multimediale Anwendungen aus dem Bereich der Kommunikation oder der Navigation große Datenmengen und Wellensignale zu übertragen sind.Another area of application for such RF lines is automotive technology, in which large amounts of data and wave signals have to be transmitted for audio systems, multimedia applications in the field of communication or navigation.
Aufgrund der von der Fahrdynamik eines Automobils stammenden Kräfte durch Vibrationen und Erschütterungen wird auch ein solcher Steckverbinder entsprechenden Kräften ausgesetzt, die zum Lösen des Kontakts zwischen den Schneiden und dem Leiter führen. Diese Gefahr des Lösens der Verbindung zwischen den Schneiden und dem Leiter wird noch aufgrund der beim Kraft- fahrzeug häufig auftretenden hohen TemperaturSchwankungen deutlich erhöht, da diese TemperaturSchwankungen zu unterschiedlichen Ausdehnungen der Schneiden und des Leiters führen.Due to the forces resulting from the driving dynamics of an automobile due to vibrations and shocks, such a connector is also subjected to corresponding forces which lead to the release of the contact between the cutting edges and the conductor. This risk of loosening the connection between the cutting edges and the conductor is significantly increased due to the high temperature fluctuations that frequently occur in the motor vehicle, since these temperature fluctuations lead to different expansions of the cutting edges and the conductor.
So kann es aufgrund von verschiedenen Ausdehnungskoeffizienten des Leiters und der Schneiden zu einer Verschiebung der Schneiden bezüglich des Leiters kommen, wodurch der Übergangswiderstand verändert wird und es so zu verschiedenen Potentialen oder Fehlkontakten kommen kann. Das vom Leiter ab- gegriffene Signal wird verfälscht.Because of different expansion coefficients of the conductor and the cutting edges, the cutting edges may shift with respect to the conductor, as a result of which the contact resistance is changed and different potentials or faulty contacts may occur. The signal picked up by the conductor is falsified.
Der Erfindung liegt daher zur Beseitigung der geschilderten Nachteile die Aufgabe zugrunde, einen Steckverbinder zu schaffen, der unter grundsätzlicher Beibehaltung der Schneid- klemmtechnik eine auch bei Temperaturschwankungen und Schwingungen unveränderte Kontaktierung mit dem Leiter zuläßt.To eliminate the disadvantages described, the invention is therefore based on the object of creating a plug connector which, while basically maintaining the insulation displacement technique, permits contact with the conductor to remain unchanged even in the event of temperature fluctuations and vibrations.
Die Erfindung weist zur Lösung dieser Aufgabe die im Anspruch 1 angegebenen Merkmale auf . Vorteilhafte Ausgestaltungen hiervon sind in den weiteren Ansprüchen beschrieben.To achieve this object, the invention has the features specified in claim 1. Advantageous refinements of this are described in the further claims.
Der vorliegenden Erfindung liegt die Erkenntnis zugrunde, daß es bei der Schneidklemmverbindung zwischen den Schneiden und dem Leiter zu einer Kaltschweißverbindung kommt und diese Verbindung bei einer Relativbewegung zwischen den Schneiden und dem Leiter aufgrund des sich einstellenden Spaltraumes zwischen den Schneiden und dem Leiter gestört wird. Es entsteht ein Luftspalt, der den elektrischen Widerstand an der Kontaktstelle zwischen den Schneiden und dem Leiter verändert . An der Kontaktstelle kommt es zu Potentialendifferenzen.The present invention is based on the finding that there is a cold welded connection in the insulation displacement connection between the cutting edges and the conductor and this connection is disturbed in the case of a relative movement between the cutting edges and the conductor due to the gap gap which arises between the cutting edges and the conductor. An air gap is created that changes the electrical resistance at the contact point between the cutting edges and the conductor. There are potential differences at the contact point.
Nach der Erfindung ist daher ein Steckverbinder für HF- Leitungen zur Kontaktierung des Außenleiters der HF-Leitung mittels einer Schneidklemmverbindung mit mindestens einem Paar gegenüberliegender Schneiden vorgesehen, bei dem die Schneiden einander gegenüberliegend in Axiallängsrichtung des Außenleiters versetzt angeordnet sind. Bei der HF-Leitung handelt es sich vorzugsweise um ein Koaxialkabel .According to the invention, therefore, a connector for HF lines for contacting the outer conductor of the HF line by means of an insulation displacement connection is provided with at least one pair of opposing cutting edges, in which the cutting edges are offset opposite one another in the axial longitudinal direction of the outer conductor. The RF line is preferably a coaxial cable.
Unter dem Begriff der gegenüberliegenden und versetzten An- Ordnung der Schneiden ist im Sinne der Erfindung zu verstehen, daß sich die Schneiden zwar an der HF-Leitung grundsätzlich einander gegenüberliegend angeordnet befinden, die Schneiden aber im Gegensatz zum bekannten Steckverbinder nicht Stirnfläche an Stirnfläche angeordnet sind, sondern in Axiallängsrichtung des Leiters gesehen hintereinander, d. h. im Abstand zueinander.The term opposite and offset arrangement of the cutting edges is to be understood in the sense of the invention that the cutting edges are basically arranged opposite one another on the HF line, but in contrast to the known plug connector the cutting edges are not arranged end-to-end , but seen one behind the other in the axial longitudinal direction of the conductor, d. H. at a distance from each other.
Mit dieser Ausbildung wird erreicht, daß die Schneiden nach dem Durchdringen der Außenisolierung der HF-Leitung mit dem Außenleiter eine KaltSchweißverbindung an der Stirnfläche und an mindestens einer angrenzenden Seitenfläche eingehen. Hierdurch wird die kontaktgebende Fläche zwischen den Schneiden und dem Außenleiter deutlich vergrößert.With this design it is achieved that after the penetration of the outer insulation of the HF line with the outer conductor, the cutting edges enter into a cold-welded connection on the end face and on at least one adjacent side face. This significantly increases the contact area between the cutting edges and the outer conductor.
Nach einer Weiterbildung der Erfindung ist es vorgesehen, daß der Steckverbinder mehrere Schneidenpaare aufweist, die zu einer in Axiallängsrichtung des Außenleiters rechtwinklig verlaufenden Ebene symmetrisch angeordnet sind. Mit dieserAccording to a development of the invention, it is provided that the connector has a plurality of pairs of cutting edges that are perpendicular to one in the axial longitudinal direction of the outer conductor extending plane are arranged symmetrically. With this
Ausbildung wird erreicht, daß die HF-Leitung zwischen den Schneiden des Steckverbinders bei der Herstellung der Schneidklemmverbindung nicht mit einer in Axiallängsrichtung des Außenleiters verlaufenden und zu einer Scherung der Leitung führenden Zugkraft beaufschlagt wird, sondern zwischen den Schneiden geringfügig gestaucht wird.Training is achieved that the RF line between the cutting edges of the connector during the manufacture of the insulation displacement connection is not subjected to a tensile force running in the axial longitudinal direction of the outer conductor and leading to shear of the line, but is slightly compressed between the cutting edges.
Der Steckverbinder kann mehrere Schneidenpaare aufweisen, die zu einer entlang der Axiallängsrichtung des Außenleiters verlaufenden Ebene symmetrisch angeordnet sind, so daß eine zu beiden Ebenen Spiegelsymmetrische Ausbildung des Steckverbinders ermöglicht wird, so daß nur eine Hälfte des Steckverbinders hergestellt werden muß und zwei Hälften über die Schnei- den ineinander gesteckt werden können, um den Steckverbinder zu bilden.The connector may have several pairs of cutting edges, which are arranged symmetrically to a plane running along the axial longitudinal direction of the outer conductor, so that a mirror-symmetrical design of the connector is made possible for both planes, so that only one half of the connector has to be manufactured and two halves over the cutting - Which can be plugged into each other to form the connector.
Die vergrößerte Kontaktfläche zwischen den Schneiden und dem Leiter führt dazu, daß die Schneiden bei einer Änderung des Abstandes ihrer Stirnflächen zueinander am Außenleiter ohne Bildung eines Spaltraumes zwischen Außenleiter und Schneiden gleiten, da die Gleitfläche weitgehend von der Seitenfläche der jeweiligen Schneide gebildet wird.The increased contact area between the cutting edges and the conductor causes the cutting edges to slide on the outer conductor when the distance between their end faces is changed, without forming a gap between the outer conductor and the cutting edges, since the sliding surface is largely formed by the side surface of the respective cutting edge.
Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in:The invention is explained below with reference to the drawing. This shows in:
Fig. l in einer perspektivischen Ansicht einen bekannten Steckverbinder;Fig. L in a perspective view of a known connector;
Fig. 2 den Steckverbinder nach Fig. 1 in einer schematischen Darstellung von der Seite;Fig. 2 shows the connector of Figure 1 in a schematic representation from the side.
Fig. 3 einen Steckverbinder nach der Erfindung in einer perspektivischen Ansicht;Figure 3 shows a connector according to the invention in a perspective view.
Fig. 4 den Steckverbinder nach Fig. 3 in einer schemati- sehen Darstellung von der Seite; und4 shows the connector according to FIG. 3 in a schematic see representation from the side; and
Fig. 5 in einer Ansicht von vorne, die zeigt, wie der Außenleiter zwischen den Schneiden des Steckverbinders geklemmt wird.Fig. 5 is a front view showing how the outer conductor is clamped between the cutting edges of the connector.
Fig. 1 und Fig. 2 der Zeichnung zeigen einen bekannten Steckverbinder 1 mit Schneiden 2, die stirnseitig aufeinander stehend angeordnet sind.Fig. 1 and Fig. 2 of the drawing show a known connector 1 with cutting edges 2, which are arranged face to face on the end.
Der Steckverbinder 1 besitzt eine weitgehend rechteckig ausgebildete Basisplatte 4, an deren Längsseiten jeweils Laschen 5 angeformt sind, so daß der Steckverbinder 1 in einer Ansicht von vorne eine U-förmige Konfiguration besitzt. Die beiden Schenkel der so gebildeten U-förmigen Anordnung werden dabei von den Laschen 5 gebildet, die die HF-Leitung 3 umgreifen.The connector 1 has a largely rectangular base plate 4, on the longitudinal sides of which tabs 5 are formed, so that the connector 1 has a U-shaped configuration in a view from the front. The two legs of the U-shaped arrangement formed in this way are formed by the tabs 5 which surround the HF line 3.
Wie es näher anhand von Fig. 2 der Zeichnung ersichtlich ist, verlaufen die Schneiden 2 des Steckverbinders 1 in jeweils einer Ebene, so daß der zwischen den Schneiden 2 geklemmte Außenleiter 8 nur von den jeweiligen Stirnflächen der Schneiden 2 erfaßt wird, so daß es bei einer beispielsweise aufgrund einer TemperaturSchwankung auftretenden Änderung des Abstandes zwischen den Schneiden 2 zu einem Spaltraum in der Kontaktfläche zwischen den Schneiden 2 und dem Außenleiter 8 kommt und Potentialendifferenzen oder Fehlkontakte die Folge sind.As can be seen in more detail with reference to FIG. 2 of the drawing, the cutting edges 2 of the connector 1 each run in one plane, so that the outer conductor 8 clamped between the cutting edges 2 is only grasped by the respective end faces of the cutting edges 2, so that it is at a change in the distance between the cutting edges 2, for example due to a temperature fluctuation, leads to a gap in the contact area between the cutting edges 2 and the outer conductor 8 and potential differences or faulty contacts result.
Fig. 3 und Fig. 4 der Zeichnung zeigen einen Steckverbinder 9 gemäß der Erfindung, der weitgehend ähnlich dem bekannten Steckverbinder l ausgebildet ist und daher in vorteilhafter Weise mit bereits vorhandenem Werkzeug geklemmt werden kann.3 and 4 of the drawing show a plug connector 9 according to the invention, which is largely similar to the known plug connector 1 and can therefore be clamped in an advantageous manner with an already existing tool.
Ein bedeutender Unterschied zwischen dem bekannten Steckverbinder 1 nach Fig. 1 und Fig. 2 und dem erfindungsgemäßen Steckverbinder 9 nach Fig. 3 und Fig. 4 besteht allerdings darin, daß sich - wie dies deutlich anhand von Fig. 4 ersichtlich ist - die Schneiden 2 nicht stirnseitig aufeinander angeordnet befinden, sondern in Axiallängsrichtung des Leiters 3 versetzt verlaufen.However, there is a significant difference between the known connector 1 according to FIGS. 1 and 2 and the connector 9 according to the invention according to FIGS. 3 and 4 in that - as can be clearly seen from FIG. 4 - the cutting edges 2 are not arranged on the end faces, but are offset in the axial longitudinal direction of the conductor 3.
Von der Basisplatte 4 des Steckverbinders 9 erstrecken sich Laschen 5 zur Bildung einer weitgehend U-förmigen Konfiguration des Steckverbinders 9 und umgreifen die HF-Leitung 3. Von den Laschen 5 erstrecken sich in einem Winkel weitgehend rechtwinklig zur Axiallängsrichtung des Leiters 3 die Schneiden 2 in Richtung zum Innenleiter 6 (siehe Fig. 5) und durchdringen dabei die Außenisolierung 7 des Leiters 3 und klemmen und verquetschen den Außenleiter 8.Tabs 5 extend from the base plate 4 of the connector 9 to form a largely U-shaped configuration of the connector 9 and encompass the HF line 3. The tabs 2 extend from the tabs 5 at an angle substantially at right angles to the axial longitudinal direction of the conductor 3 Direction to the inner conductor 6 (see FIG. 5) and penetrate the outer insulation 7 of the conductor 3 and clamp and squeeze the outer conductor 8.
Wie es dabei näher aus Fig. 4 ersichtlich ist, kommt es aufgrund der axial versetzten Anordnung der Schneiden 2 nicht nur zu einem Kontakt zwischen den jeweiligen Stirnflächen 10 der Schneiden 2 und dem Außenleiter 8, sondern auch zu einem flächigen Kontakt zwischen den Seitenflächen 11 der Schneiden 2 und dem Außenleiter 8.As can be seen in more detail from FIG. 4, due to the axially offset arrangement of the cutting edges 2, there is not only contact between the respective end faces 10 of the cutting edges 2 and the outer conductor 8, but also a flat contact between the side surfaces 11 of the Cutting 2 and the outer conductor 8.
Dieser flächige Kontakt führt dazu, daß es auch bei einer Abstandsänderung der Schneiden 2 zueinander nicht zur Bildung eines Spaltraumes im Kontaktflächenbereich kommt, sondern die Schneiden 2 auf dem Außenleiter 8, der bei einem Koaxialkabel aus einem Schirmgeflecht besteht, gleiten und somit keine Änderung des Übergangswiderstandes erfolgt.This two-dimensional contact leads to the fact that even when the spacing of the cutting edges 2 from one another does not lead to the formation of a gap space in the contact surface area, the cutting edges 2 slide on the outer conductor 8, which in the case of a coaxial cable consists of a braided shield, and thus no change in the contact resistance he follows.
Wie es darüber hinaus leicht anhand von Fig. 3 ersichtlich ist, weist der Steckverbinder 9 an den Längsseiten seiner Basisplatte 4 jeweils zwei Laschen 5 auf, die Schneidenpaare mit unterschiedlichen axialen Abständen a, b der Schneiden 2 besitzen.3, the connector 9 has on the long sides of its base plate 4 two tabs 5, which have pairs of blades with different axial distances a, b of the blades 2.
Der Steckverbinder 9 kann aus zwei Hälften zusammengesetzt werden, wobei eine aus einem Blechteil gefertigte Hälfte mit einer weiteren Hälfte zum Steckverbinder 9 zusammengesetzt werden kann, indem die Schneidenpaare einander übergreifend angeordnet werden. Zu diesem Zweck besitzen die Laschen 5 Aufnahmen 12, in die Rastnasen 13 der jeweils anderen Steckverbinderhälfte eingreifen und einrasten können. Diese Aus- bildung kommt dem Erfordernis einer kostengünstigen Ausbildung für die Massenfertigung besonders entgegen.The connector 9 can be composed of two halves, with a half made from a sheet metal part being assembled with another half to form the connector 9 can be arranged by overlapping the pairs of cutting edges. For this purpose, the tabs 5 have receptacles 12 which can engage and engage in the locking lugs 13 of the other connector half. This training meets the requirement of inexpensive training for mass production in particular.
Die vorstehend beschriebene Ausführungsform gemäß der vorliegenden Erfindung dient der Erläuterung, nicht aber der Be- schränkung halber. Demgemäß kann die Erfindung anhand anderer Ausführungsformen ausgeführt werden, ohne aber von der Erfindung abzuweichen.The embodiment described above according to the present invention serves for explanation, but not for the sake of limitation. Accordingly, the invention can be carried out on the basis of other embodiments, but without deviating from the invention.
Die Erfindung ist anhand eines Ausführungsbeispieles zum Ver- binden zweier Koaxialleitungen beschrieben worden. Im Rahmen der Erfindung liegt selbstverständlich auch eine Ausführungsform, bei der ein Stecker (Buchsen- oder Stiftstecker) mit der erfindungsgemäßen Schneidenanordnung mit dem Leiter verbunden wird.The invention has been described using an exemplary embodiment for connecting two coaxial lines. Of course, an embodiment is also within the scope of the invention in which a plug (socket or pin plug) is connected to the conductor with the cutting edge arrangement according to the invention.
