Abstract

The coaxial plug connector has at least one cylindrical contact member (1), which is provided with an annular groove (3). A contact spring strip (6) divided into spring laminates by axial slits is inserted into the annular groove (3). In the connected state, the spring strip (6) elastically contacts the cladding surface of a counter contact member (2) which telescopically engages one of the contact members (1). An axial groove type cut (5) is formed in one of the annular groove side walls (4). An edge (7) of the contact spring strip (6) can be inserted into the groove cut (5). Preferably the width of the contact spring strip is selected to be greater than the width of the annular groove (3). The axial width of the groove and the width of the spring strip may be selected such that the spring strip holds itself in the annular groove.

Description

Die Erfindung betrifft eine koaxiale Steckverbindung laut Oberbegriff des Hauptanspruches.The invention relates to a coaxial connector according to the preamble of the main claim.

Koaxiale Steckverbindungen dieser Art sind bekannt (DE 38 14 069). Sie werden zur Kontaktierung des Innen­ leiters oder Außenleiters von steckbaren Koaxialleitungs­ stücken eingesetzt. Das Kontaktfederband ist jeweils in der am Innenleiter bzw. Außenleiter ausgebildeten Ringnut durch Punktschweißen, Nieten oder durch Verpressen gehalten.Coaxial connectors of this type are known (DE 38 14 069). They are used to contact the inside conductor or outer conductor of pluggable coaxial line pieces used. The contact spring band is in each case in the trained on the inner conductor or outer conductor Ring groove by spot welding, riveting or by pressing held.

Es ist Aufgabe der Erfindung, eine Steckverbindung dieser Art mit einer in der Herstellung einfacheren Kontaktfederhalterung zu schaffen.It is an object of the invention to provide a connector of this type with a simpler to manufacture To create contact spring bracket.

Diese Aufgabe wird ausgehend von einer koaxialen Steck­ verbindung laut Oberbegriff des Hauptanspruches durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This task is based on a coaxial plug connection according to the preamble of the main claim its characteristic features solved. Beneficial Further training results from the subclaims.

Bei einer erfindungsgemäßen Steckverbindung wird die Kontaktfeder einfach in die Ringnut eingelegt und mit ihrem Rand in die nutartige Hinterdrehung eingeschoben, sie hält sich dann in der Ringnut von selbst und kann nicht herausfallen. Es ist nur erforderlich, das Kontakt­ federband in der richtigen Länge abzulängen und in die Nut einzulegen, zusätzliche Befestigungsmaßnahmen wie Punktschweißen, Nieten oder Verpressen werden überflüssig. Damit können solche Steckverbindungen wesentlich einfacher, preiswerter und schneller hergestellt werden. Außerdem kann die Kontaktfeder jederzeit auf einfache Weise ausgewechselt werden.In a connector according to the invention Contact spring simply inserted into the ring groove and with its edge inserted into the groove-like backward rotation,  it then holds itself in the ring groove and can don't fall out. It is only necessary to make contact Cut the spring band to the correct length and in insert the groove, additional fastening measures such as spot welding, riveting or pressing superfluous. This allows such plug connections manufactured much easier, cheaper and faster will. In addition, the contact spring can be opened at any time be replaced easily.

Die erfindungsgemäße Kontaktfederhalterung ist sowohl am Innenleiter als auch am Außenleiter anwendbar, er eignet sich sowohl für bleibende Koaxialleitungsver­ bindungen als auch für Steckkontakte mit häufigem Kontaktwechsel.The contact spring holder according to the invention is both applicable on the inner conductor as well as on the outer conductor, it is suitable for permanent coaxial line bindings as well as for plug contacts with frequent Change of contact.

Die Erfindung wird im folgenden anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.The invention will now be described more schematically Drawings explained in more detail using an exemplary embodiment.

Fig. 1 zeigt im vergrößerten Maßstab die Anwendung der erfindungsgemäßen Kontaktfederhalterung bei einer bleibenden Innenleiterverbindung zwischen dem Innen­ leiter-Kontaktstück 1 eines nicht näher dargestellten koaxialen Winkelstücks und einem damit mit gutem Kontakt zu verbindenden Innenleiterrohr 2 einer ebenfalls nicht näher dargestellten Koaxialleitung. Am Innen­ leiter-Kontaktstück 1 ist eine Ringnut 3 ausgebildet, die gemäß der in noch größerem Maßstab dargestellten Detaildarstellung nach Fig. 2 in der einen Seitenwand 4 eine nutartige Hinterschneidung 5 aufweist. In dieser Ringnut 3 ist eine in den Fig. 3 bis 5 in Draufsicht, Seitenansicht und Stirnansicht näher dargestelltes Kontaktfederband 6 eingesetzt, das durch axiale Schlitze in Federlamellen unterteilt ist. Diese Lamellen sind im dargestellten Ausführungsbeispiel halbkreisförmig gebogen oder bombiert, sie können jedoch auch nur in bekannter Weise um einen kleinen Winkel geschränkt sein. Die Länge dieses Kontaktfederbandes 6 ist entsprechend dem Umfang der Ringnut 3 gewählt, die Höhe a der Hinter­ schneidung 5 ist etwas größer als die Dicke e des Kontaktfederbandes 6 gewählt, die Tiefe b der Hinter­ schneidung 5 ist so gewählt, daß die Gesamtbreite c von Ringnut 3 plus Tiefe b der Hinterschneidung etwa so groß bzw. etwas größer als die Breite d der Kontaktfeder 6 ist. Die richtig abgelängte Kontaktfeder 6 beispielsweise aus Berylliumkupfer wird einfach um den Außenumfang der Ringnut 3 gebogen bis sie mit ihrem Rand 7 am ganzen Umfang in die Hinterschneidung 5 einschnappt und am Boden der Ringnut 3 am ganzen Umfang flach anliegt und sich somit selbst in der Ringnut hält und nicht herausfallen kann. Beim Zusammen­ stecken der Innenleiterteile 1 und 2 des Ausführungs­ beispiels nach Fig. 1 wird das Innenleiterrohr 2 in Richtung des Pfeiles 8 über die Kontaktfeder 6 aufgeschoben, bis der Rand 9 am Anschlag 10 anschlägt. In der so hergestellten Innenleiterverbindung wird dann über die dazwischenwirkende Kontaktfeder 6 ein guter elektrischer Kontakt zwischen den Innenleiterteilen 1 und 2 hergestellt. Fig. 1 shows on an enlarged scale the application of the contact spring holder according to the invention with a permanent inner conductor connection between the inner conductor contact piece 1 of a coaxial angle piece, not shown, and an inner conductor tube 2, which is also to be connected with good contact, of a coaxial line, also not shown. On the inner conductor contact piece 1 , an annular groove 3 is formed, which has a groove-like undercut 5 in one side wall 4 in accordance with the detailed illustration shown in FIG. 2 shown in an even larger scale. In this annular groove 3 , a contact spring band 6 is shown, which is shown in more detail in FIGS . 3 to 5 in plan view, side view and end view and is divided into spring slats by axial slots. In the exemplary embodiment shown, these lamellae are curved or cambered in a semicircular shape, but they can also be limited by only a small angle in a known manner. The length of this contact spring band 6 is selected according to the circumference of the annular groove 3 , the height a of the rear cut 5 is selected slightly greater than the thickness e of the contact spring band 6 , the depth b of the rear cut 5 is selected so that the total width c of the annular groove 3 plus depth b of the undercut is approximately as large or slightly larger than the width d of the contact spring 6 . The correctly cut contact spring 6, for example made of beryllium copper, is simply bent around the outer circumference of the annular groove 3 until it snaps with its edge 7 over the entire circumference into the undercut 5 and lies flat against the entire circumference at the bottom of the annular groove 3 and thus holds itself in the annular groove and cannot fall out. When the inner conductor parts 1 and 2 of the embodiment according to FIG. 1 are put together, the inner conductor tube 2 is pushed in the direction of arrow 8 via the contact spring 6 until the edge 9 strikes the stop 10 . In the inner conductor connection produced in this way, good electrical contact between the inner conductor parts 1 and 2 is then established via the contact spring 6 acting therebetween.
