Beschreibung description
Die Erfindung betrifft einen koaxialen Steckverbinder der im Oberbegriff des Anspruches 1 genannten Art. The invention relates to a coaxial connector of the type mentioned in the preamble of claim 1.
Steckverbinder dieser Gattung für hochwertige Koaxialkabel, insbesondere solche mit massivem Aussenleiter, der glatt, schraubenförmig gewellt oder ringförmig gewellt sein kann, sind allgemein bekannt. Connectors of this type for high-quality coaxial cables, in particular those with a solid outer conductor that can be smooth, corrugated or ring-shaped, are generally known.
Zur Verbesserung der mechanischen Klemmung, vor allem aber zur sicheren elektrischen Kontaktie-rung wird der Aussenleiter häufig im Bereich seines Stirnendes aufgeweitet oder rechtwinklig nach aussen unter Bildung eines Kragens umgebördelt. Der aufgeweitete Bereich oder der Kragen wird zwischen einer entsprechenden Ringfläche des Steckverbindergehäuses und der ringförmigen Stirnfläche oder auch Kegelfläche eines Druckringes durch Eindrehen eines hohlen Schraubgliedes, dessen Stirnfläche auf dem Druckring aufliegt, festgeklemmt und dadurch gleichzeitig auch mit dem Steckverbindergehäuse elektrisch kontaktiert. In order to improve the mechanical clamping, but above all for reliable electrical contacting, the outer conductor is often widened in the region of its front end or flanged outward at a right angle to form a collar. The widened area or the collar is clamped between a corresponding annular surface of the connector housing and the annular end surface or conical surface of a pressure ring by screwing in a hollow screw member, the end surface of which rests on the pressure ring, and at the same time thereby makes electrical contact with the connector housing.
Es hat sich nun gezeigt, dass diese sehr nieder-ohmige und daher reflexionsarme Kontaktierung in manchen Fällen dennoch unbefriedigend ist, nämlich dann, wenn ein besonders hoher Intermodulati-onsabstand, z.B. von mehr als 120 dB für die Inter-modulationsprodukte dritter Ordnung, gefordert wird. Dies ist z.B. bei Koaxialverbindern der Fall, über die gleichzeitig Signale mit hoher Leistung gesendet und mit sehr kleiner Leistung empfangen werden. It has now been shown that this very low-ohmic and therefore low-reflection contacting is nevertheless unsatisfactory in some cases, namely when a particularly high intermodulation distance, e.g. of more than 120 dB for the third order inter-modulation products. This is e.g. the case with coaxial connectors, via which signals with high power are simultaneously sent and received with very low power.
Der Erfindung liegt daher die Aufgabe zugrunde, einen besonders intermodulationsarmen koaxialen Steckverbinder der einleitend angegebenen Art zu schaffen. The invention is therefore based on the object of providing a particularly low-intermodulation coaxial connector of the type specified in the introduction.
Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Patentanspruches 1 angegeben. The solution to this problem is specified in the characterizing part of claim 1.
Die scheinbar einfache Lösung, bei einem Steckverbinder der vorliegenden Gattung den Aussenleiter mit dem Steckverbindergehäuse zu verlöten, setzt die Erkenntnis voraus, dass die Intermodulati-onssignale mit dem gemessenen Pegel ihre Ursache in der bisherigen Art der mechanischen Kontaktierung haben, dass nämlich bei dieser Art der Kontaktierung der Kontaktwiderstand einen wenn auch sehr kleinen nichtlinearen Anteil hat, der die Ursache für die Entstehung von Intermodulationssi-gnalen ist. Zurückzuführen ist dieser nichtlineare Anteil vermutlich auf die im Kontaktierungsbereich aufeinandertreffenden, gewöhnlich unterschiedlichen Metalle und vor allem deren Oberflächenoxyde, die wiederum bei den für die Aussenleiter von Koaxialkabeln meist verwendeten Metallen, nämlich Kupfer bzw. Kupferlegierungen und Aluminium, unvermeidbar sind. Die allgemein bekannte halbleitende Wirkung beispielsweise von Kupferoxydul könnte als Bestätigung der diesseitigen Vermutung angesehen werden. The apparently simple solution of soldering the outer conductor to the connector housing in a connector of the present type presupposes the knowledge that the intermodulation signals with the measured level have their cause in the previous type of mechanical contacting, namely in this type of Contacting the contact resistance has a very small non-linear component, which is the cause of the generation of intermodulation signals. This non-linear portion is probably due to the usually different metals encountering one another in the contact area and, above all, their surface oxides, which in turn are unavoidable with the metals mostly used for the outer conductors of coaxial cables, namely copper or copper alloys and aluminum. The well-known semiconducting effect of copper oxide, for example, could be seen as confirmation of this assumption.
Die mit dem Anspruch 1 vorgeschlagene Lösung hat zudem den Vorteil, dass das Steckverbindergehäuse insgesamt einstückig ausgebildet werden kann, also die bisher benötigten, weiteren Teile, nämlich zumindest der Druckring und das hohle Schraubglied, entfallen können. Des weiteren braucht der Aussenleiter im Kontaktierungsbereich auch nicht mehr aufgeweitet oder umgebördelt zu werden. The solution proposed with claim 1 also has the advantage that the connector housing as a whole can be formed in one piece, that is, the previously required further parts, namely at least the pressure ring and the hollow screw member, can be omitted. Furthermore, the outer conductor in the contact area no longer needs to be widened or flanged.
Bei den häufig anzutreffenden Koaxialkabeln mit schraubenförmig gewelltem Aussenleiter empfiehlt sich die Ausführungsform nach Anspruch 2. Die zu der Wellung des Aussenleiters komplementäre Profilierung der Innenwand des Steckverbindergehäuses erleichert die Montage und Positionierung des Steckers auf dem Koaxialkabel bis zum Abschluss des Lötvorganges. In the case of frequently encountered coaxial cables with a helically corrugated outer conductor, the embodiment according to claim 2 is recommended. The profiling of the inner wall of the connector housing, which is complementary to the corrugation of the outer conductor, simplifies the assembly and positioning of the plug on the coaxial cable until the soldering process is complete.
Die Verlötung des Steckverbindergehäuses mit dem Kabelaussenleiter erfolgt am besten mittels einer das Steckverbindergehäuse von aussen um-schliessenden, beheizten Zange, bevor das Innenleiterkontaktelement und das Steckverbinderdielektrikum in dem Steckverbindergehäuse montiert werden. The best way to solder the connector housing to the cable outer conductor is to use heated pliers to enclose the connector housing from the outside before the inner conductor contact element and the connector dielectric are mounted in the connector housing.
In der einzigen Figur der Zeichnung ist der Steckverbinder nach der Erfindung in einer schematisch vereinfachten, beispielhaft gewählten Ausführungsform im Längsschnitt dargestellt. In the single figure of the drawing, the connector according to the invention is shown in a schematically simplified, exemplary embodiment chosen in longitudinal section.
In der Figur bedeuten: In the figure:
1 = Kabelinnenleiter 1 = inner cable
2 = Kabeldielektrikum 2 = cable dielectric
3 = Kabelaussenleiter 3 = outer cable
4 = Kabelmantel 4 = cable sheath
11 = Innenleiterkontaktelement des Steckverbinders 11 = inner conductor contact element of the connector
12 = Steckerdielektrikum 12 = connector dielectric
13 = Steckverbindergehäuse 13 = connector housing
14 = steckseitiger Flansch 14 = plug-side flange
Der Kabelaussenleiter 3 ist im Kontaktierungsbereich 20 über seinen gesamten Aussenumfang mit der Innenwand des Steckverbindergehäuses 13 verlötet, das einstückig ausgebildet ist und ein zu der schraubenförmigen Wellung des Kabelaussenlei-ters 3 komplementäres Profil hat, wie bei 13a angedeutet. Bei dieser Ausführungsform müssen das Steckverbinderdielektrikum 12 und das Innenleiterkontaktelement 11 von der Steckseite, also in der Zeichnung von links, eingebaut werden. Der steck-seitige Flansch 14 ist als Schraubflansch ausgebildet und hat eine nach innen vorspringende Ringschulter 14a zur Sicherung der Lage des Steckverbinderdielektrikums 12. Der Kabelinnenleiter 1 ist in einer entsprechenden Bohrung des Innenleiterkon-taktelements 11 aufgenommen und in dieser verlötet. Um den Lötvorgang zu ermöglichen, hat das Innenleiterkontaktelement 11 eine zu der Lötstelle führende, axiale Bohrung 11a. The cable outer conductor 3 is soldered in the contacting area 20 over its entire outer circumference to the inner wall of the connector housing 13, which is formed in one piece and has a profile complementary to the helical corrugation of the cable outer conductor 3, as indicated at 13a. In this embodiment, the plug connector dielectric 12 and the inner conductor contact element 11 must be installed from the plug side, that is to say from the left in the drawing. The plug-side flange 14 is designed as a screw flange and has an inwardly projecting annular shoulder 14a for securing the position of the plug connector dielectric 12. The inner cable conductor 1 is received in a corresponding bore in the inner conductor contact element 11 and is soldered therein. In order to enable the soldering process, the inner conductor contact element 11 has an axial bore 11a leading to the soldering point.
Da der Kabelaussenleiter 3 ringsum mit dem Steckverbindergehäuse 13 verlötet ist, kann etwa von der Kabelseite her eindringendes Wasser an keiner Stelle in den Bereich zwischen dem Innenleiterkontaktelement des Steckverbinders und dessen Aussenleiter gelangen. Die Verlötung im Kontaktierungsbereich 20 erfolgt am besten mittels einer das Steckverbindergehäuse 13 von aussen umschlies-senden, beheizten Zange geeigneter Form, bevor das Innenleiterkontaktelement 11 und das Steckverbinderdielektrikum 12 in das Steckverbindergehäuse 13 eingesetzt werden. Since the cable outer conductor 3 is soldered all around to the connector housing 13, water penetrating from the cable side cannot get anywhere in the area between the inner conductor contact element of the connector and its outer conductor. The soldering in the contacting area 20 is best carried out by means of a suitable shape of heated pliers which surround the connector housing 13 from the outside before the inner conductor contact element 11 and the connector dielectric 12 are inserted into the connector housing 13.
