Kupplungselement zum Verbinden der Enden von koaxialen HochfrequenzkabelnCoupling element for connecting the ends of coaxial high-frequency cables
Die Erfindung betrifft ein lösbares koaxiales Kupplungselement zum mechanischen und elektrischen Verbinden von koaxialen Hochfrequenz-Kabelenden, welche mit Anschlußvorrichtungen versehen sind, deren kupplungsseitige Enden eine Stirnfront mit einem daran anschließenden Außengewindestutzen besitzen, bestehend aus einem in einem Isolierteil eingeschlossenen Innenleiterverbindungsglied und einem das Isolierteil umgebenden im wesentlichen zylinderförmlgen Gehäuse als Außenleiter.The invention relates to a releasable coaxial coupling element for the mechanical and electrical connection of coaxial High-frequency cable ends, which are provided with connection devices the ends of which on the coupling side have a front face with an adjoining male thread connector, consisting of an inner conductor connecting member enclosed in an insulating part and one surrounding the insulating part essentially cylindrical housing as the outer conductor.

konzentrisch aufgebaute Kupplungselemente Verwendung. Dabei wurden bereits an den beiden Kabelenden angebrachte Anschluß-Vorrichtungen für CATV-Garnituren vorgeschlagen, welche von einem koaxialen Kupplungselement überbrückt wurden derart, daß eine mechanisch und somit auch elektrisch jederzeit lösbare Verbindung entsteht.concentrically constructed coupling elements use. In this case, connection devices for CATV sets attached to the two cable ends have already been proposed, which by a coaxial coupling element were bridged in such a way that a mechanically and thus also electrically detachable connection is created at any time.
Ein Nachteil dieses Kupplungselementes ist die Anzahl und der komplizierte Aufbau der hierfür benötigten Bauteile. Weiterhin ist nachteilig, daß die Klemmwirkung der geschlitzten Hülse für den Innenleiter nachläßt, weil die verwendeten Konen zwangsläufig aus Kunststoff bestehen müssen, welcher mit der Zeit unter dem Einfluß der Temperaturschwankungen zum Fließen neigt, so daß die Spannkonen mechanisch und elektrisch nicht mehr den Forderungen gerecht werden, welche z.B. an CATV-Oarnitüren gestellt werden müssen.A disadvantage of this coupling element is the number and the complicated structure of the components required for this. A further disadvantage is that the clamping effect of the slotted Sleeve for the inner conductor wears off because the cones used must necessarily be made of plastic, which tends to flow over time under the influence of temperature fluctuations, so that the clamping cones no longer mechanically and electrically meet the requirements which e.g. must be placed at CATV fittings.
Der Erfindung liegt die Aufgabe zugrunde, ein Kupplungselement der obengenannten Art anzugeben, welches unter Verwendung weniger, einfacher Bauteile von Alterungseffekten frei, mechanisch und elektrisch unempfindlich und gasdioht ist.The invention is based on the object of a coupling element of the type mentioned above, which is free of aging effects, mechanically and electrically insensitive and gas-resistant using a few, simple components.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse des Kupplungselementes über in gegenüberliegenden Offnungen angebrachte Innengewinde mit den Außengewindestutzen der Ansohlußvorriohtungen versohraubt und mittels Stirnkontakten dioht verbunden ist, daß die Stirnkontakte gleichzeitig als Metalldiohtungen ausgebildet sind, daß in Reihe mit den Stirnkontakten je ein Gummiring als zusätzliche Dichtung angeordnet ist, daß das Innenlelterverblndungsglied in dem als Kunststoffspritzteil ausgebildeten Isolierteil gelagert; ist, daß das Isolierteil mittels Preßsü;z innerhalb des Gehäuses fixiert ist, wobei es Ausstülpungen zur Aufnahme von der ArretierungThe object is achieved according to the invention in that the housing of the coupling element over in opposite Openings attached internal threads with the external threaded connector the Ansohlußvorriohtungen verohraubt and by means of forehead contacts dioht is connected that the front contacts are designed as Metalldiohtungen at the same time that in series with the front contacts a rubber ring is arranged as an additional seal is that the inner parent connecting member is mounted in the insulating part designed as a plastic injection-molded part; is that that The insulating part is fixed within the housing by means of Preßsü; z, with protuberances for receiving the locking device

Das Gehäuse des Kupplungselementes und die Anschlußvorrichtun&en an den Xabelenden lassen sich über deren jeweilige Stirnfronten mittels der Schraubgewinde mit dem nötigen Kontaktdruck rasch, bequem und verdrehungssicher kontaktieren, so daß eine durchgehende Störstrahlungsdichte Verbindung für den Außenleiter geschaffen wird. Die beim Festschrauben sich bildenden beiden Metalldichtungen an den Stirnfronten sind zusätzlich mit dem in Reihe liegenden Gummiring gesichert. Die Innenleiterenden des Kabels nimmt das Innenleiterverbindungsglied des Kupplungselementes auf, welches in dem Isolierteil aus Kunststoff zentriert und unverrückbar eingegossen ist. Dabei ist das Isolierteil seinerseits an den beiderseitigen Innengewinden der die kupplungsseitigen Enden der Anschluß-Vorrichtungen aufnehmenden Gehäuseöffnungen durch Preßsitz verankert. Zum Auffangen der Alterungseffekte des Kunststoffes werden die Innenleiterenden des Kabels im Innenleiterverbindungsglied des Kupplungselementes festgeschraubt, wobei die Stiftschrauben in den Ausstülpungen des Isolierteiles stecken und somit beim Montieren unverlierbar sind. Das Verschrauben erfolgt dabei übur die Gehäuseöffnung mit Gewinde, welche mit einem gummigediohteten aufschraubbaren Einsatz gasdicht verschließbar ist.The housing of the coupling element and the connecting devices The screw threads can be used to apply the necessary contact pressure to the ends of the Xabel via their respective fronts contact quickly, conveniently and twist-proof, so that a continuous interference radiation-proof connection for the Outer conductor is created. The two metal seals that are formed on the fronts when screwing are in addition secured with the rubber ring lying in a row. The inner conductor connector takes the inner conductor ends of the cable of the coupling element, which is centered in the insulating part made of plastic and cast immovably. The insulating part is in turn on the internal threads on both sides of the coupling-side ends of the connection devices receiving housing openings anchored by a press fit. To absorb the aging effects of the plastic the inner conductor ends of the cable in the inner conductor connector of the coupling element is screwed tight, the studs sticking into the protuberances of the insulating part and thus cannot be lost during assembly. The screwing takes place over the housing opening with thread, which with a rubber-coated screw-on insert that can be closed in a gastight manner is.
Ferner ist es vorteilhaft, wenn die Längsbohrung des Innenleiterverbindungsgliedes nach dem größten vorkommenden Innenleiterdurchmeaser der verwendeten Kabel bemessen ist. Hierdurch ergibt sich die Möglichkeit auch Kabeltypen mit verschieden dimensionierten Innenleitern miteinander zu kuppeln. Besitzt ferner die Innenwand des Innenleiterverblndung3glledes gegenüber den die Stiftschrauben in den Ausstülpungen aufnehmendenIt is also advantageous if the longitudinal bore of the inner conductor connecting member according to the largest occurring inner conductor diameter the cable used is dimensioned. This results in the possibility of different types of cables dimensioned inner conductors to be coupled together. Also has the inner wall of the inner conductor connection 3glledes opposite which receive the studs in the protuberances

Denn ein Im Vergleich zur öffnungswe:1 Je des Innenleiterverbindungsgliedes schwach diemensionierter Innenleiter kann sicher arretiert werden, weil beim Festschrauben der schwache Innenleiter in die Ausnehmung des Innenleiterverbindungsgliedes gedrückt vird. Damit läßt sich ein breites Spektrum von Kabeltypen kuppeln.Bores, recesses, the inner conductor can be firmly anchored in the inner conductor connecting member. Because a Compared to öffnungswe: 1 slightly diemensionierter The inner conductor of the link inner conductor can be securely locked because vird pressed when tightening the weak inner conductor in the recess of the inner conductor connecting member. This enables a wide range of cable types to be coupled.
Weiterhin ist es vorteilhaft, wenn die realtive Dielektrizitätszahl des das Innenleiterverbindungsglied tragenden Isolierteiles<2,5 ist.It is also advantageous if the relative dielectric constant of the insulating part carrying the inner conductor connecting member <2.5 is.
Das erfindungsgemäße Kupplungselement wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert: Dabei zeigt die Figur die Seitenansicht eines Halbschnittes durch ein Kupplungselement, welches zwei Kabelenden mit aufmontierten Anschlußvorrichtungen verbindet.The coupling element according to the invention is explained in more detail below using an exemplary embodiment: FIG Figure the side view of a half section through a coupling element, which has two cable ends with mounted connection devices connects.
