Description

Die Erfindung betrifft einen Koaxialverbinder mit einem Innenleiter, einem Außenleiter und einem Überspannungsschutz mit einer Induktivität nach Masse und einem Kondensator, wobei der Kondensator in Serie mit dem Innenleiter geschaltet ist und eine erste Kondensatorplatte aufweist, welche mit einem ersten Innenleiter eines Eingangs des Koaxialverbinders verbunden ist, und eine zweite Kondensatorplatte aufweist, welche mit einem zweiten Innenleiter eines Ausgangs des Koaxialverbinders verbunden ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a coaxial connector with an inner conductor, an outer conductor and a surge protector with a ground inductance and a Capacitor, the capacitor being connected in series with the inner conductor and has a first capacitor plate, which with a first inner conductor an input of the coaxial connector is connected, and a second capacitor plate which has a second inner conductor of an output of the coaxial connector is connected, according to the preamble of claim 1.

Aus der US 6 061 223 ist ein Koaxialverbinder mit Blitzschutz bekannt, bei dem eine mäanderförmige Spule den Innenleiter mit dem Außenleiter verbindet. Diese Spule erstreckt sich radial ausgehend vom Innenleiter nach außen bis zum Außenleiter und schließt niederfrequente Ströme, wie beispielsweise aufgrund von Spannungen bei einem Blitzeinschlag, gegen Masse kurz. Andererseits werden hochfrequente Ströme nicht über die Spule abgeleitet, sondern passieren den Innenleiter in axialer Richtung. Zusätzlich ist der Innenleiter mit einem Kondensator ausgestattet. Dieser läßt hochfrequente Ströme passieren und blockiert niederfrequente Ströme aufgrund von Restspannungen bei Ableitung eines Blitzeinschlages über die Spule. Bei dieser Anordnung werden also unerwünschte Spannungsschläge gegen Masse abgeleitet, ohne die Übertragungseigenschaften des Koaxialverbinders für Hochfrequenz nennenswert zu beeinträchtigen. Die Energie beispielsweise eines Blitzeinschlages wird dabei radial über die mäanderförmige Spule nach Masse abgeleitet. Diese bekannte Anordnung hat jedoch den Nachteil, daß die Herstellung der mäanderförmigen Spule schwierig und kostenintensiv ist. Ferner kommt es zu einer entsprechenden Krafteinwirkung auf die mäanderförmige Spule, wenn diese bei der Ableitung von Energie stromdurchflossen ist, wobei die Krafteinwirkung die Spule verformt und um so größer ist, je größer der Stromfluß ist. Aufgrund der begrenzten mechanischen Festigkeit der mäanderförmigen Spule ist die Stromübertragungskapazität entsprechend begrenzt, da ein mechanischer Bruch der Spule zu einer Fehlfunktion des Überspannungsschutzes führt.From US 6 061 223 a coaxial connector with lightning protection is known in which a meandering coil connects the inner conductor to the outer conductor. This The coil extends radially from the inner conductor outwards to the outer conductor and closes low frequency currents, such as due to Lightning strikes, short to ground. On the other hand high-frequency currents are not discharged via the coil, but pass through the inner conductor in the axial direction. In addition, the inner conductor with a capacitor fitted. This allows high-frequency currents to pass and blocks low-frequency ones Currents due to residual voltages when a lightning strike is derived over the coil. With this arrangement there are therefore undesirable voltage shocks derived to ground without the transmission properties of the coaxial connector noticeable for high frequency. The energy, for example A lightning strike is radial over the meandering Coil derived by mass. However, this known arrangement has the disadvantage that the manufacture of the meandering coil is difficult and expensive. There is also a corresponding force on the meandering Coil, if current flows through it when dissipating energy, whereby the force deforms the coil and the greater the current flow, the greater it is is. Due to the limited mechanical strength of the meandering Coil, the current transmission capacity is limited due to a mechanical Breakage of the coil leads to a malfunction of the surge protection.

Aus der GB 21 94 394 A ist ein Koaxialverbinder mit integrierter elektrischer Schaltung bekannt. Auf einer Leiterplatte ist ein PI-Filter aufgebracht. Zwischen einem Innenleiter eines Koaxialkabels und einem Innenleiterkontaktelement des Koaxialverbinders ist in einer Ausnehmung der Leiterplatte eine Axialspule angeordnet, deren Enden mit jeweils einem gegen Masse geschalteten und auf der Leiterplatte aufgebrachten Kondensator in Verbindung stehen.GB 21 94 394 A is a coaxial connector with integrated electrical Circuit known. A PI filter is applied to a circuit board. Between an inner conductor of a coaxial cable and an inner conductor contact element of the An axial coil is arranged in a recess of the printed circuit board, the ends of which are each connected to ground and on the PCB attached capacitor.

Der Erfindung liegt die Aufgabe zugrunde, einen Koaxialverbinder der o.g. Art bzgl. Herstellung und Montage zu verbessern.The invention has for its object to provide a coaxial connector of the above. kind to improve manufacturing and assembly.

Diese Aufgabe wird erfindungsgemäß bei einem Koaxialverbinder der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved in a coaxial connector of the above. Kind with solved the features characterized in claim 1. Advantageous configurations the invention are described in the further claims.

Erfindungsgemäß ist vorgesehen, daß die Induktivität als Axialspule ausgebildet sowie koaxial zum Innenleiter angeordnet ist, wobei ein erstes Ende der Axialspule mit der ersten Kondensatorplatte verbunden ist und ein zweites, dem Kondensator abgewandtes Ende der Axialspule an einer axial in Richtung Eingang des Koaxialverbinders beabstandeten Stelle mit dem Außenleiter verbunden ist.According to the invention it is provided that the inductance is designed as an axial coil and is arranged coaxially to the inner conductor, with a first end of the axial coil is connected to the first capacitor plate and a second, the capacitor opposite end of the axial coil at an axially towards the entrance of the coaxial connector spaced point is connected to the outer conductor.

Dies hat den Vorteil, daß das Spulenelement des Überspannungsschutzes einfacher herzustellen ist und gleichzeitig eine höhere mechanische Festigkeit aufweist. Zusätzlich kommt es wegen der Ausbildung als Axialspule zu einer gleichmäßigen Krafteinwirkung auf die Spule bei Stromfluß. Durch den erfindungsgemäßen Aufbau ist es möglich, einen größeren Leitungsquerschnitt zu verwenden. Dies erzielt eine bessere Stabilität und eine höhere Stromübertragungskapazität. Mit anderen Worten ist ein Überspannungsschutz für noch höhere Ströme gewährleistetThis has the advantage that the coil element of the surge protector is simpler is to be produced and at the same time has a higher mechanical strength. In addition, because of the design as an axial coil, there is a uniform Force on the coil when current flows. Due to the structure according to the invention it is possible to use a larger cable cross-section. This achieved better stability and higher power transmission capacity. With others Words, surge protection is guaranteed for even higher currents

In einer bevorzugten Ausführungsform weist die Axialspule einen dielektrischen Grundkörper auf, auf dem Spulenwicklungen aus einem Draht aus leitendem Werkstoff aufgebracht sind.In a preferred embodiment, the axial coil has a dielectric Base body on which coil windings made of a wire made of conductive Material are applied.

In einer alternativen Ausführungsform sind die Axialspule und die erste Kondensatorplatte einstückig aus einem an einer Seite geschlossenen Rohr aus leitendem Werkstoff ausgebildet, wobei an der geschlossenen Seite die erste Kondensatorplatte ausgebildet ist und wobei ferner das Rohr zwischen der geschlossenen Seite und einer offenen Seite einen helixförmig um eine Rohrwandung herum verlaufenden Schlitz aufweist, welcher die Rohrwandung in entsprechende Spulenwindungen zu einer Axialspule aufteilt.In an alternative embodiment, the axial coil and the first capacitor plate in one piece from a tube made of conductive on one side Material formed, the first capacitor plate on the closed side is formed and further the tube between the closed Side and an open side a helical around a pipe wall extending slot, which the tube wall in corresponding coil turns divides into an axial coil.

Eine einfachere Montage sowie eine kostengünstige Herstellung erzielt man dadurch, daß der erste Innenleiter einstückig mit der ersten Kondensatorplatte ausgebildet ist.Easier installation and cost-effective production can be achieved by that the first inner conductor is formed in one piece with the first capacitor plate is.

Zweckmäßigerweise ist das erste Ende der Axialspule im Bereich eines äußeren Umfangsrandes der ersten Kondensatorplatte mit dieser elektrisch verbunden.The first end of the axial coil is expediently in the region of an outer one Peripheral edge of the first capacitor plate electrically connected to this.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in:

Fig. 2
eine zweite bevorzugte Ausführungsform eines erfindungsgemäßen Koaxialverbinders in geschnittener, perspektivischer Ansicht.
The invention is explained in more detail below with reference to the drawing. This shows in:
Fig. 1
a first preferred embodiment of a coaxial connector according to the invention in sectional view and
Fig. 2
a second preferred embodiment of a coaxial connector according to the invention in a sectional, perspective view.

Die in Fig. 1 dargestellte, erste bevorzugte Ausführungsform eines erfindungsgemäßen Koaxialverbinders mit Überspannungsschutz umfaßt einen Eingang 10, einen Ausgang 12, einen mit dem Eingang 10 verbundenen ersten Innenleiter 14, einen mit dem Ausgang 12 verbundenen zweiten Innenleiter 16 und einen Außenleiter 18. Als Überspannungsschutz ist ein Kondensator 20 mit einer mit dem ersten Innenleiter 14 verbundenen ersten Kondensatorplatte 22 und einer mit dem zweiten Innenleiter 16 verbundenen zweiten Kondensatorplatte 24 vorgesehen.1, the first preferred embodiment of an inventive Coaxial connector with surge protection includes an input 10, an output 12, a first inner conductor 14 connected to the input 10, a second inner conductor 16 connected to the output 12 and an outer conductor 18. As overvoltage protection is a capacitor 20 with one first inner conductor 14 connected first capacitor plate 22 and one with the second inner conductor 16 connected second capacitor plate 24 is provided.

Der Überspannungsschutz umfaßt ferner eine Induktivität, welche in Form einer Helixspule 26 ausgehend von der ersten Kondensatorplatte 22 in Richtung Eingang 10 den ersten Innenleiter 14 koaxial umgibt. Ein erstes Ende 28 der Helixspule 26 ist mit der ersten Kondensatorplatte 22 benachbart zu deren Außenumfang elektrisch verbunden. Ein zweites, von dem Kondensator 20 abgewandtes Ende 30 der Helixspule 26 ist mit dem Außenleiter 18 elektrisch verbunden. Die Helixspule 26 ist auf ein rohrförmiges Dielektrikum 32 aufgeschoben, welches von dem ersten Innenleiter 14 gehalten ist und eine gewünschte Impedanz einstellt. Die Helixspule ist derart ausgebildet, daß sie zwischen dem ersten und dem zweiten Ende ihren Durchmesser nicht verändert, sondern sich im wesentlichen in axialer Richtung erstreckt.The overvoltage protection also includes an inductor, which is in the form of a Helix coil 26 starting from the first capacitor plate 22 in the direction of the input 10 coaxially surrounds the first inner conductor 14. A first end 28 of the helical coil 26 is with the first capacitor plate 22 adjacent to its outer periphery electrically connected. A second, facing away from the capacitor 20 End 30 of helical coil 26 is electrically connected to outer conductor 18. The Helix coil 26 is pushed onto a tubular dielectric 32, which of the first inner conductor 14 is held and sets a desired impedance. The helical coil is designed such that it is between the first and the second end does not change its diameter, but essentially in extends in the axial direction.

Mit dieser Anordnung sind über den Eingang 10 ankommende, niederfrequente Ströme ausgehend von dem ersten Innenleiter 14 über die erste Kondensatorplatte 22 und die Helixspule 26 gegen Masse bzw. Erde kurz geschlossen. Für hochfrequente Ströme, wie beispielsweise über den Koaxialverbinder übertragene Nutzsignale im MHz- oder GHz-Bereich, bildet die Helixspule eine Drossel, so daß derartige Ströme nicht über die Helixspule nach Masse abfließen, sondern von dem ersten Innenleiter 14 über den Kondensator 20 zum zweiten Innenleiter 16 und damit zum Ausgang 12 übertragen werden.With this arrangement, low-frequency are arriving via the input 10 Currents starting from the first inner conductor 14 via the first capacitor plate 22 and the helical coil 26 short-circuited to earth or ground. For high-frequency currents, such as those transmitted via the coaxial connector Useful signals in the MHz or GHz range, the helical coil forms a choke, so that such currents do not flow to ground via the helical coil, but from the first inner conductor 14 via the capacitor 20 to the second inner conductor 16 and thus be transmitted to output 12.

Im Falle einer Überspannung am Eingang 10, beispielsweise als Folge eines Blitzeinschlages, treten hohe, jedoch niederfrequente Ströme auf, deren Energie axial über die Helixspule 26 gegen Masse abgeführt wird. Gleichzeitig schützt der Kondensator 20 dem Ausgang 12 nachgeordnete elektrische Schaltungen vor etwaigen Restspannungen, welche während der Energieabführung über die Helixspule 26 auftreten.In the event of an overvoltage at input 10, for example as a result of a lightning strike, high, but low-frequency currents occur whose energy is axial is discharged to ground via the helical coil 26. At the same time, the capacitor protects 20 the output 12 downstream electrical circuits before any Residual voltages that occur during the energy dissipation via the helical coil 26 occur.

In gleicher Weise funktioniert die zweite bevorzugte Ausführungsform gemäß Fig. 2, jedoch ist hier der Überspannungsschutz aus Helixspule 26 und Kondensator 20 in mechanisch anderer Weise aufgebaut. Die erste Kondensatorplatte 22 und die Helixspule 26 sind einstückig aus einem an einem Ende geschlossenen Rohr 34 gefertigt. Hierbei ist die erste Kondensatorplatte 22 beispielsweise durch Abdrehen eines Teils des Umfangs des Rohres 34 an dessen geschlossenem Ende ausgebildet. Am zylinderförmigen Umfang des Rohres 34 erstreckt sich ferner ein Schlitz helixförmig zwischen dem geschlossenen Ende und dem offenen Ende des Rohres 34 und teilt dadurch einen vorbestimmten Abschnitt einer Rohrwandung des Rohres 34 in nebeneinander liegende Windungen auf, so daß die Helixspule 26 auf dem zylinderförmigen Rohrmantel ausgebildet ist. Der erste Innenleiter 14 ist beispielsweise in die erste Kondensatorplatte 22 eingeschraubt, eingepreßt oder einstückig mit dieser ausgebildet.The second preferred embodiment according to FIG Fig. 2, but here is the overvoltage protection from helix coil 26 and capacitor 20 constructed in a mechanically different way. The first capacitor plate 22 and the helical coil 26 are integral from a closed at one end Tube 34 made. Here, the first capacitor plate 22 is, for example, through Twisting off part of the circumference of the tube 34 at its closed end educated. Also extends on the cylindrical circumference of the tube 34 a helical slot between the closed end and the open end of the pipe 34 and thereby divides a predetermined portion of a pipe wall of the tube 34 in adjacent turns, so that the helical coil 26 is formed on the cylindrical tubular jacket. The first inner conductor 14 is screwed, for example, into the first capacitor plate 22 or integrally formed with this.

Bei dieser zweiten Ausführungsform ist die Induktivität in Form der Helixspule besonders einfach, schnell, kostengünstig und in Serien- bzw. Massenproduktion herzustellen. Hierzu ist lediglich eine entsprechende Fräs-/Drehbearbeitung eines Rohrrohlings durchzuführen.In this second embodiment, the inductance in the form of the helical coil is special simple, fast, inexpensive and in series or mass production manufacture. All that is required is a corresponding milling / turning operation To perform pipe blanks.
