Abstract
Description
Die Erfindung geht von einem koaxialen Stecker nach dem Oberbegriff des Anspruchs 1 aus. Derartige Stecker dienen zum reflexionsfreien Abschluß von Hochfrequenzkabeln.The invention is based on a coaxial connector according to the preamble of claim 1. Such connectors are used for reflection-free Completion of high-frequency cables.
Es ist ein Koaxialstecker mit einem Abschlußwiderstand bekannt, bei dem in einem Steckergehäuse ein Isolierstoffteil befestigt ist, das einen koaxialen Innenleiterstift trägt. In dem Steckergehäuse ruht auf dem Isolierstoffteil ein weiteres Isolierstoffteil, welches eine axiale Öffnung zur Aufnahme des Abschlußwiderstandes enthält. Ein Anschluß des Abschlußwiderstandes ist mit dem Innenleiterstift und der andere Anschluß mit einem metallischen Deckel leitend verbunden, der das Steckergehäuse an dem dem Steckerstift abgewandten Ende ab schließt. Der technische Aufwand für die Herstellung dieses koaxialen Steckers und ähnlicher bekannter koaxialer Stecker mit Abschlußwider stand ist verhältnismäßig hoch.A coaxial connector with a terminating resistor is known at which is attached to an insulating part in a connector housing carries a coaxial inner conductor pin. It rests in the connector housing on the insulating part another insulating part, which a contains axial opening for receiving the terminating resistor. A Connection of the terminating resistor is with the inner conductor pin and the other connection is conductively connected with a metallic cover, from the connector housing on the end facing away from the connector pin closes. The technical effort for the production of this coaxial Plug and similar known coaxial connector with terminating resistor level is relatively high.
Der Erfindung liegt die Aufgabe zugrunde, einen koaxialen Stecker der gattungsgemäßen Art derart weiterzubilden, daß er bei einfachem Auf bau mechanisch stabil ist und alle an ihn gestellten hochfrequenztech nischen Forderungen erfüllt. The invention has for its object a coaxial connector Generic type in such a way that he with a simple up construction is mechanically stable and all high-frequency technology placed on it requirements.
Diese Aufgabe wird bei einem gattungsgemäßen koaxialen Stecker durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß der Stecker ein fach und preisgünstig herstellbar ist. Ein bevorzugtes Anwendungsgebiet für den Stecker sind Kabelfernsehanlagen.This task is performed by a generic coaxial connector characterizing features of claim 1 solved. The one with the invention Achievable advantages are in particular that the plug can be produced professionally and inexpensively. A preferred area of application for the plug are cable television systems.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung an Hand zweier Figuren dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is in the drawing on hand shown two figures and will be described in more detail below. It shows
Fig. 1 einen Längsschnitt durch einen Koaxialstecker mit Abschlußwiderstand in vergrößertem Maßstab und Fig. 1 shows a longitudinal section through a coaxial connector with terminating resistor on an enlarged scale and
Fig. 2 eine Ansicht des Koaxialsteckers nach Fig. 1 von unten bei abgenommenem Deckelteil. Fig. 2 is a view of the coaxial connector of FIG. 1 from below with the cover part removed.
Nach Fig. 1 hat ein Koaxialstecker 10 ein rohrförmiges Steckergehäuse 11, das an seinen oberen Ende 12 einen ersten Durchmesser hat, der auf etwa halber Länge in einen zweiten, etwas größeren Durchmesser übergeht. Der an der Übergangsstelle entstehende Absatz 13 dient als Auflage für eine in das Steckergehäuse eingefügte runde Leiterplatte 14 aus Kunststoff, in deren zentrischer Öffnung 15 ein Ansatz 16 eines Steckerstiftes 17 befestigt ist. Der Durchmesser des Ansatzes 16 ist vorzugsweise etwas kleiner als der Durchmesser des Steckerstiftes. Der Ansatz 16 ragt etwas aus der Leiterplatte 14 heraus. Auf dieser Seite trägt die Leiterplatte Leiterbahnen 18, 19, 20, von denen die Leiterbahn 20 vorzugsweise in ein den Ansatz 16 umgebendes Lötauge 21 übergeht (vgl. Fig. 2). Die Leiter bahnen 18 und 20 bilden Lötanschlüsse für einen Abschlußwiderstand 23, der vorteilhafterweise als SMD-Baustein ausgebildet ist. According to Fig. 1, a coaxial connector 10 has, which passes a tubular connector housing 11 which has at its upper end 12 of a first diameter to about half its length in a second, somewhat larger diameter. The resulting paragraph 13 at the transition serves as a support for a plastic circuit board 14 inserted into the connector housing, in the central opening 15 of which an attachment 16 of a connector pin 17 is fastened. The diameter of the extension 16 is preferably somewhat smaller than the diameter of the plug pin. The approach 16 protrudes somewhat from the circuit board 14 . On this side, the circuit board carries conductor tracks 18 , 19 , 20 , from which the conductor track 20 preferably merges into a pad 21 surrounding the attachment 16 (cf. FIG. 2). The conductor tracks 18 and 20 form solder connections for a terminating resistor 23 , which is advantageously designed as an SMD module.
Durch eine ringförmige Eindrückung 24 an der Außenseite des Stecker gehäuses 11 (Fig. 1) wird die Leiterplatte 14 in dem Steckergehäuse fixiert und eine elektrische Verbindung zwischen dem Steckergehäuse und der Leiterbahn 18 hergestellt. Die Leiterbahn 19, die den Leiter bahnen 18 und 20 diametral gegenüberliegt, dient lediglich als Höhen ausgleich. Ein Deckelteil 25 aus Kunststoff oder Metall ist in das Steckergehäuse 11 eingedrückt und schließt dieses nach unten ab.By means of an annular indentation 24 on the outside of the connector housing 11 ( FIG. 1), the circuit board 14 is fixed in the connector housing and an electrical connection is established between the connector housing and the conductor track 18 . The conductor track 19 , the tracks 18 and 20 diametrically opposite the conductor, only serves as height compensation. A cover part 25 made of plastic or metal is pressed into the plug housing 11 and closes it off at the bottom.
