- the RF conductor is also surrounded by a solid dielectric over at least part of its length, which is surrounded by an outer conductor over at least part of its length, so that the RF conductor constitutes the inner conductor of a coaxial cable to be picked up or received.
- the connection device in this case is a connector.
- the connector has an outer conductor socket for receiving the coaxial cable.
- the outer conductor bushing has an outer conductor contacting section, at which the outer conductor of the male or female coaxial cable is electrically contacted with the outer conductor socket of the connecting device.
- the connection connection has at least one matching element.
- the at least one matching element is arranged between the outer conductor contacting section and the HF conductor receiving element and preferably radially surrounds the HF conductor alone or together with the dielectric of the coaxial cable to be picked up or received. This allows the characteristic impedance of the coaxial cable to be adjusted to a desired value.
- the RF conductor is inserted together with the insert sleeve and with the at least one solder deposit in the RF conductor receiving element of the connection device.
- the RF conductor is inserted into the receiving opening of the insert sleeve or into the receiving opening of the insert sleeve and the annular solder depot.

Description
Die Erfindung betrifft eine Anschlussverbindung zur Aufnahme und Kontaktierung für HF-Leiter, insbesondere für solche eines Koaxialkabels.The invention relates to a connection connection for receiving and contacting for RF conductors, in particular for those of a coaxial cable.
Anschlussverbindungen, wie Steckverbindungen im Generellen dienen dem Trennen, bzw. dem Verbinden von elektrischen Leitungen, um hierüber Strom und/oder vor allem elektrische Signale zu übertragen. Es kann sich hierbei um Mehrfach- oder um Einfach-Stecker handeln. Große Bedeutung haben im Bereich der Steckverbinder die koaxialen Steckverbindungen, die einen Innenleiter sowie einen Außenleiter und in der Regel eine Außenleiterabschirmung umfassen, wobei der Innenleiter gegenüber dem Außenleiter in der Regel unter Verwendung eines Dielektrikums elektrisch/galvanisch getrennt ist.Connection connections, such as plug connections in general, are used for disconnecting or connecting electrical lines in order to transmit current and / or, above all, electrical signals. This can be a multiple or single plug. Of great importance in the area of the connectors are the coaxial plug-in connections, which comprise an inner conductor and an outer conductor and, as a rule, an outer conductor shield, the inner conductor being electrically / galvanically isolated from the outer conductor, generally using a dielectric.
Wünschenswert ist dabei, dass das Koaxialkabel möglichst einfach mit dem Steckverbinder in Kontakt gebracht werden kann. Dieser Kontakt soll dabei möglichst reproduzierbar sein.It is desirable that the coaxial cable as easy as possible be brought into contact with the connector can. This contact should be as reproducible as possible.

Der elektrische Kontakt zwischen dem HF-Innenleiter und dem der Anschlusseinrichtung soll dabei auch reproduzierbar und möglichst einfach realisierbar sein.It is therefore the object of the present invention to provide a terminal connection, by which a connection device can be connected to an RF inner conductor in the simplest possible way, and this with different cables. The electrical contact between the RF inner conductor and the connection device should also be reproducible and as simple as possible.
Die Aufgabe wird durch die Anschlussverbindung gemäß dem unabhängigen Anspruch 1 gelöst. Der Anspruch 13 beschreibt ein elektronisches Gerät, insbesondere einen HF-Filter, der die erfindungsgemäße Anschlussverbindung umfasst. Innerhalb des Anspruchs 15 wird zusätzlich ein Verfahren zur Herstellung einer solchen Anschlussverbindung beschrieben. In den Unteransprüchen finden sich vorteilhafte Weiterbildungen der erfindungsgemäßen Anschlussverbindung, bzw. des elektronischen Geräts oder des erfindungsgemäßen Verfahrens zum Herstellen einer solchen Anschlussverbindung.The object is achieved by the connection according to the
Die erfindungsgemäße Anschlussverbindung erlaubt die Aufnahme und Kontaktierung eines HF-Leiters mit einer Anschlusseinrichtung, beispielsweise in Form eines Steckverbinders. Die Anschlusseinrichtung weist einen HF-Leiter und ein HF-Leiteraufnahmeelement mit einer HF-Leiteraufnahmebohrung zur Aufnahme des HF-Leiters auf. Die Anschlussverbindung sieht ebenfalls den Einsatz von zumindest einem Lotdepot vor, das zur Herstellung einer elektrisch leitfähigen Verbindung zwischen dem HF-Leiter und dem HF-Leiteraufnahmeelement der Anschlusseinrichtung dient.The connection of the invention allows the recording and contacting of an RF conductor with a connection device, for example in the form of a connector. The connection device has an HF conductor and an HF conductor receiving element with an HF conductor receiving bore for receiving the HF conductor. The connection connection also provides for the use of at least one solder deposit, which serves for producing an electrically conductive connection between the HF conductor and the HF conductor receiving element of the connection device.
Die Anschlussverbindung sieht ebenfalls eine Einsatzhülse vor, die über eine Aufnahmeöffnung verfügt. In die Aufnahmeöffnung ist dabei der HF-Leiter eingeführt. Die Einsatzhülse ist über eine einsteckseitige Einführöffnung in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements eingeführt. Das zumindest eine Lotdepot ist dabei entweder in der Einsatzhülse oder an zumindest einer der beiden Stirnseiten der Einsatzhülse oder an dem HF-Leiter angeordnet. Die Einsatzhülse ist dabei entweder unverformbar und/oder sie besteht aus einem Dielektrikum. In Ergänzung oder alternativ dazu ist die Einsatzhülse bezüglich ihrer Umfangs-Seitenfläche an eine Innenfläche der HF-Leiteraufnahmebohrung angepasst und stützt sich an dieser ab und ist nur in Längsrichtung innerhalb der HF-Leiteraufnahmebohrung verschiebbar. Zusätzlich oder alternativ weist die Einsatzhülse zumindest einen Aufnahmekanal auf, der von außen nach innen in die Aufnahmeöffnung verläuft, wobei der zumindest eine Aufnahmekanal zur Aufnahme des zumindest einen Lotdepots dient.The connection connection also provides an insert sleeve which has a receiving opening. In the receiving opening while the RF conductor is inserted. The insert sleeve is inserted via an insertion-side insertion opening in the RF conductor receiving bore of the RF conductor receiving element. The at least one solder deposit is arranged either in the insert sleeve or on at least one of the two end sides of the insert sleeve or on the RF conductor. The insert sleeve is either undeformable and / or it consists of a dielectric. In addition or alternatively, the insert sleeve is adapted with respect to its peripheral side surface to an inner surface of the RF conductor receiving bore and is supported on this and is displaceable only in the longitudinal direction within the RF conductor receiving bore. Additionally or alternatively, the insert sleeve has at least one receiving channel which extends from the outside to the inside into the receiving opening, wherein the at least one receiving channel serves to receive the at least one solder deposit.
Besonders vorteilhaft ist die Verwendung einer sogenannten Einsatzhülse, die in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements eingeführt ist. Diese Einsatzhülse kann direkt über ein Lotdepot verfügen oder ein Lotdepot ist an der Einsatzhülse, also benachbart zu dieser angeordnet. Beim Aufschmelzen dieses Lotdepots verbindet sich dann der HF-Leiter mit dem HF-Leiteraufnahmeelement. Die Einsatzhülse bewirkt einerseits, dass das Lotdepot an einer genau vorgeschriebenen Stelle angeordnet ist, wodurch eine genaue und reproduzierbare Kontaktierung des HF-Leiters mit dem HF-Leiteraufnahmeelement erfolgt. Andererseits ist sichergestellt, dass für verschiedene Durchmesser des HF-Leiters die gleiche Anschlusseinrichtung verwendet werden kann. Es muss lediglich eine andere Einsatzhülse mit einer anderen Aufnahmeöffnung verwendet werden, die an den jeweils aufzunehmenden HF-Leiter angepasst ist. Folglich weisen die Einsatzhülsen zwar unterschiedliche Durchmesser bzgl. ihrer Aufnahmeöffnung auf, besitzen allerdings dennoch den gleichen Außendurchmesser, sodass eine einheitliche HF-Leiteraufnahmebohrung verwendet werden kann. Außerdem kann immer frisches Lot verwendet werden, weil dies nicht innerhalb der HF-Leiteraufnahmebohrung angeordnet ist und dort bis zum Lötvorgang altert. Die Anschlusseinrichtung selbst kann daher beliebig lange gelagert werden und wird erst im Zuge der Vereinigung mit dem HF-Leiter mit einer Einsatzhülse, die bevorzugt über ein frisches, also nicht gealtertes Lotdepot verfügt, versehen.Particularly advantageous is the use of a so-called insert sleeve, which is inserted into the RF conductor receiving bore of the RF conductor receiving element. This insert sleeve can have a solder deposit directly or a solder deposit is arranged on the insert sleeve, ie adjacent to it. When melting this solder deposit then connects the RF conductor with the RF conductor receiving element. On the one hand, the insert sleeve causes the solder deposit to be arranged at a precisely prescribed location, whereby an exact and reproducible contacting of the HF conductor with the HF conductor receiving element takes place. On the other hand, it is ensured that the same connection device can be used for different diameters of the HF conductor. It is only necessary to use a different insert sleeve with a different receiving opening, which is adapted to the particular RF conductor to be recorded. Consequently, although the insert sleeves have different diameters with respect to their receiving opening, they nevertheless have the same outer diameter, so that a uniform HF conductor receiving bore can be used. In addition, fresh solder can always be used because it is not located within the RF conductor receiving bore and ages there until soldering. The connection device itself can therefore be stored for any length of time and is provided only in the course of association with the RF conductor with an insert sleeve, which preferably has a fresh, that is not aged, solder deposit.
Im Rahmen der Erfindung zeigt sich daher, dass sich die Anschlusseinrichtung zur Aufnahme von Innenleitern mit unterschiedlichen Durchmessern gleichermaßen eignet.In the context of the invention, it is therefore evident that the connection device is equally suitable for accommodating inner conductors with different diameters.
In einem nebengeordneten Anspruch verfügt ein elektronisches Gerät, bei welchem es sich insbesondere um ein HF-Filter handelt, über die erfindungsgemäße Anschlusseinrichtung. Die HF-Leiteraufnahmebohrung ist dabei beispielsweise in einem Resonator-Innenleiter des HF-Filters ausgebildet, in welche die Einsatzhülse zusammen mit dem Lotdepot eingebracht wird. Schlussendlich ist der HF-Leiterin die Einsatzhülse eingeführt und mit dem HF-Leiteraufnahmeelement verlötet.In an independent claim, an electronic device, which is in particular an HF filter, has the connection device according to the invention. The RF conductor receiving bore is, for example, in a resonator inner conductor of the RF filter formed, in which the insert sleeve is introduced together with the solder deposit. Finally, the RF conductor is inserted into the insert sleeve and soldered to the RF conductor receiving element.
Ein weiterer Vorteil besteht, wenn die Einsatzhülse unverformbar, also unelastisch ist, weil dadurch der Abstand zwischen dem HF-Leiter hin zu dem HF-Leiteraufnahmeelement konstant ist und eine hohe Reproduzierbarkeit der Lötstelle gewährleistet ist. Die Einsatzhülse besteht dabei aus einem Dielektrikum, insbesondere einem Kunststoff. Ein Kunststoff besitzt eine geringe Wärmekapazität, so dass bei einer induktiven Erwärmung des Lotdepots weniger Energie benötigt wird, bzw. der Aufschmelzvorgang in kürzerer Zeit erfolgen kann, als wenn die Einsatzhülse aus einem Metall hergestellt wäre, was auch möglich sein könnte. Die Einsatzhülse ist außerdem bezüglich ihrer Umfangs-Seitenfläche an die Innenfläche der HF-Leiteraufnahmebohrung angepasst und zwar sowohl vom Durchmesser, als auch von der Form und stützt sich daher dieser ab und ist nur in Längsrichtung innerhalb der HF-Leiteraufnahmebohrung verschiebbar. Bei der Einsatzhülse und dem HF-Leiteraufnahmeelement, welches die HF-Leiteraufnahmebohrung aufweist, handelt es sich um zwei getrennte Elemente. Dies bedeutet, dass die Einsatzhülse und das HF-Leiteraufnahmeelement zweiteilig ausgebildet sind. Die HF-Leiteraufnahmebohrung wird durch das Anbringen der Einsatzhülse unverändert gelassen.Another advantage is when the insert sleeve is undeformable, that is inelastic, because thereby the distance between the RF conductor towards the RF conductor receiving element is constant and a high reproducibility of the solder joint is ensured. The insert sleeve consists of a dielectric, in particular a plastic. A plastic has a low heat capacity, so that when an inductive heating of the solder deposit less energy is needed, or the melting process can be done in less time than if the insert sleeve would be made of a metal, which could also be possible. The insert sleeve is also adapted with respect to its peripheral side surface to the inner surface of the RF conductor receiving bore, both the diameter, as well as the shape and therefore supports this and is displaceable only in the longitudinal direction within the RF conductor receiving bore. The insert sleeve and the RF conductor receiving element, which has the RF conductor receiving bore, are two separate elements. This means that the insert sleeve and the RF conductor receiving element are formed in two parts. The RF conductor receiving bore is left unchanged by attaching the insert sleeve.
Ein weiterer Vorteil besteht dann, wenn das Lotdepot aus einem festen oder elastischen Material besteht und vorzugsweise die Form eines teilweise offenen oder geschlossenen Rings aufweist, der oder wenn das Lotdepot zähflüssig ist. Insbesondere ein Einsatz eines Lotdepots, das aus einem festen oder elastischen Material in Form eines offenen oder geschlossenen Rings besteht, bewirkt, dass dieses Lotdepot sehr einfach auf den HF-Leiter aufgesetzt werden kann.Another advantage is when the solder deposit is made of a solid or elastic material and preferably in the form of a partially open or closed Rings, or if the solder deposit is viscous. In particular, a use of a solder deposit, which consists of a solid or elastic material in the form of an open or closed ring, causes this solder depot can be very easily placed on the RF conductor.
Die Einsatzhülse weist ebenfalls bevorzugt an ihrem Umfang zumindest ein Kodierelement auf, wodurch die Einsatzhülse nur in einer bestimmten Position verdrehsicher in das HF-Leiteraufnahmeelement eingeführt werden kann. Die Einsatzhülse kann optional oder zusätzlich an ihrem Umfang auch zumindest einen entgegen der Einführrichtung in das HF-Leiteraufnahmeelement vorstehenden als Widerhaken wirkenden Abschnitt aufweisen, wodurch ein Herausrutschen der Einsatzhülse aus dem HF-Leiteraufnahmeelement verhindert wird. Dies bewirkt, dass das Lotdepot immer in der gleichen Position zusammen mit der Einsatzhülse in die Anschlusseinrichtung eingeführt wird. Das Kodierelement kann auch in der Form der Einsatzhülse gesehen werden. Für den Fall, dass die Einsatzhülse keinen runden Querschnitt, sondern einen ovalen oder n-eckigen Querschnitt, mit n ≥ 3 aufweist, kann bereits ein Verdrehen verhindert werden. Allerdings muss dann die HF-Leiteraufnahmebohrung mit einem anderen Prozess hergestellt werden. Dadurch wird die Reproduzierbarkeit der elektrischen Kontaktierung weiter erhöht. Die Tatsache, dass die Einsatzhülse eine Art Widerhaken aufweist, bewirkt außerdem eine vereinfachte Montage, weil die Einsatzhülse nicht mehr aus der HF-Leiteraufnahmebohrung herausrutschen kann.The insert sleeve likewise preferably has at least one coding element on its circumference, as a result of which the insert sleeve can only be inserted into the HF conductor receiving element so that it can not rotate in a specific position. The insert sleeve may optionally or additionally have at its circumference at least one contrary to the direction of insertion into the RF conductor receiving element protruding barb acting portion, whereby slipping out of the insert sleeve is prevented from the RF conductor receiving element. This causes the solder deposit to always be inserted in the same position together with the insert sleeve in the connection device. The coding element can also be seen in the form of the insert sleeve. In the event that the insert sleeve does not have a round cross-section, but an oval or n-shaped cross-section, with n ≥ 3, already twisting can be prevented. However, then the RF conductor receiving bore must be made with another process. As a result, the reproducibility of the electrical contact is further increased. The fact that the insert sleeve has a kind of barb, also causes a simplified assembly, because the insert sleeve can not slip out of the RF conductor receiving bore.
Die Einsatzhülse ist bevorzugt anschlagsbegrenzt innerhalb des HF-Leiteraufnahmeelements angeordnet, so dass ebenfalls eine Reproduzierbarkeit der elektrischen Kontaktierung erhöht wird, weil der Abstand des zumindest einen Lotdepots zum HF-Leiteraufnahmeelement bei einer Vielzahl von Anschlusseinrichtungen gleich ist.The insert sleeve is preferably arranged stop-limited within the RF conductor receiving element, so that a reproducibility of the electrical contact is also increased, because the distance of the at least one solder deposit to the RF conductor receiving element is the same for a plurality of connection devices.
Der Aufnahmekanal hat insbesondere die Form einer Bohrung. Der Aufnahmekanal erstreckt sich vorzugsweise radial von außen nach innen in die Aufnahmeöffnung, wobei der zumindest eine Aufnahmekanal zur Aufnahme von dem zumindest einen Lotdepot dient. Besonders vorteilhaft ist hierbei, dass die Einsatzhülse zusammen mit dem Lotdepot entsprechend vorbereitet werden kann, bis es letztlich zur Vereinigung der Anschlusseinrichtung mit dem HF-Leiter kommt.The receiving channel has in particular the form of a bore. The receiving channel preferably extends radially from the outside inwards into the receiving opening, wherein the at least one receiving channel serves for receiving the at least one solder depot. It is particularly advantageous in this case that the insert sleeve can be prepared appropriately together with the solder depot until it finally comes to unification of the connection device with the RF conductor.
Es ist auch möglich, dass die Einsatzhülse X Aufnahmekanäle aufweist, mit X ≥ 2, wobei diese Aufnahmekanäle in Draufsicht auf einen Querschnitt durch die Einsatzhülse um α = 360°/X beabstandet zueinander angeordnet sind. Dies bewirkt, dass eine elektrische Kontaktierung des HF-Leiters mit dem HF-Leiteraufnahmeelement symmetrisch erfolgt, wodurch die Reproduzierbarkeit der elektrischen Verbindung erhöht wird.It is also possible that the insert sleeve has X receiving channels, with X ≥ 2, wherein these receiving channels are arranged in a plan view of a cross section through the insert sleeve by α = 360 ° / X spaced from each other. This causes an electrical contact of the RF conductor with the RF conductor receiving element takes place symmetrically, whereby the reproducibility of the electrical connection is increased.
Es ist auch möglich, dass der Aufnahmekanal die Form eines Ausschnitts aufweist, der in Draufsicht auf einen Querschnitt durch die Einsatzhülse einen Bereich von mehr als 180°, bevorzugt von mehr als 220°, weiter bevorzugt von mehr als 260°, weiter bevorzugt von mehr als 300°, weiter bevorzugt von mehr als 340°, aber weniger als 360° umfasst. Innerhalb dieses Ausschnitts kann besonders einfach ein Lotdepot angeordnet werden, welches die Form eines offenen Rings umfasst und aus einem festen oder teilweise elastischen Material besteht. Dieses Lotdepot kann einfach in den Aufnahmekanal, der die Form eines Ausschnitts hat "eingeclipst" werden.It is also possible that the receiving channel has the shape of a cutout, which in plan view of a cross section through the insert sleeve, a range of more than 180 °, preferably more than 220 °, more preferably more than 260 °, more preferably more than 300 °, more preferably more than 340 ° but less than 360 °. Within this section can be special simply a solder deposit can be arranged, which comprises the shape of an open ring and consists of a solid or partially elastic material. This solder deposit can simply be "clipped" into the pick-up channel, which has the shape of a cut-out.
Der HF-Leiter ist außerdem zumindest über einem Teil seiner Länge von einem festen Dielektrikum umgeben, das zumindest über einen Teil seiner Länge von einem Außenleiter umgeben ist, so dass der HF-Leiter den Innenleiter eines aufzunehmenden oder aufgenommenen Koaxialkabels darstellt. Bei der Anschlusseinrichtung handelt es sich in diesem Fall um einen Steckverbinder. Der Steckverbinder weist eine Außenleiterbuchse zur Aufnahme des Koaxialkabels auf. Die Außenleiterbuchse weist einen Außenleiterkontaktierungsabschnitt auf, an dem der Außenleiter des aufzunehmenden oder aufgenommenen Koaxialkabels mit der Außenleiterbuchse der Anschlusseinrichtung elektrisch kontaktiert ist. Die Anschlussverbindung weist dabei zumindest ein Anpasselement auf. Das zumindest ein Anpasselement ist zwischen dem Außenleiterkontaktierungsabschnitt und dem HF-Leiteraufnahmeelement angeordnet und umgibt den HF-Leiter alleine oder zusammen mit dem Dielektrikum des aufzunehmenden oder aufgenommenen Koaxialkabels vorzugsweise radial. Dadurch kann der Wellenwiderstand des Koaxialkabels auf einen gewünschten Wert angepasst werden.The RF conductor is also surrounded by a solid dielectric over at least part of its length, which is surrounded by an outer conductor over at least part of its length, so that the RF conductor constitutes the inner conductor of a coaxial cable to be picked up or received. The connection device in this case is a connector. The connector has an outer conductor socket for receiving the coaxial cable. The outer conductor bushing has an outer conductor contacting section, at which the outer conductor of the male or female coaxial cable is electrically contacted with the outer conductor socket of the connecting device. The connection connection has at least one matching element. The at least one matching element is arranged between the outer conductor contacting section and the HF conductor receiving element and preferably radially surrounds the HF conductor alone or together with the dielectric of the coaxial cable to be picked up or received. This allows the characteristic impedance of the coaxial cable to be adjusted to a desired value.
Das erfindungsgemäße Verfahren zum Herstellen einer Anschlussverbindung umfasst die folgenden Verfahrensschritte: In einem ersten Verfahrensschritt muss der aufzunehmende HF-Leiter vorbereitet werden. Dies kann geschehen durch:
- a) Aufeinanderfolgendes oder gleichzeitiges Aufsetzen eines Lotdepots auf den HF-Leiter und weiteres Aufsetzen der Einsatzhülse auf den HF-Leiter; oder
- b) Aufeinanderfolgendes oder gleichzeitiges Aufsetzen der Einsatzhülse und eines Lotdepots auf den HF-Leiter; oder
- c) Aufsetzen der Einsatzhülse auf den HF-Leiter, wobei das zumindest eine Lotdepot bereits in der Einsatzhülse angeordnet ist; oder
- d) Aufsetzen der Einsatzhülse auf den HF-Leiter und Anbringen von dem zumindest einen Lotdepot in der Einsatzhülse.
- a) Successive or simultaneous placement of a solder deposit on the RF conductor and further placing the insert sleeve on the RF conductor; or
- b) successive or simultaneous placement of the insert sleeve and a solder deposit on the RF conductor; or
- c) placing the insert sleeve on the HF conductor, wherein the at least one solder deposit is already arranged in the insert sleeve; or
- d) placing the insert sleeve on the RF conductor and attaching the at least one solder deposit in the insert sleeve.
Im Anschluss daran wird der HF-Leiter zusammen mit der Einsatzhülse und mit dem zumindest einen Lotdepot in das HF-Leiteraufnahmeelement der Anschlusseinrichtung eingeführt.Subsequently, the RF conductor is inserted together with the insert sleeve and with the at least one solder deposit in the RF conductor receiving element of the connection device.
Statt des ersten Verfahrensschritts kann die Anschlusseinrichtung in einem zweiten Verfahrensschritt entsprechend vorbereitet werden. Dies geschieht durch:
- a) Anordnung von dem zumindest einen Lotdepot in der Einsatzhülse und Einführung der Einsatzhülse mit dem zumindest einen Lotdepot in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung; oder
- b) Einführen der Einsatzhülse in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung und Einführen oder Einbringen eines Lotdepots in den zur Einführöffnung hin verbleibenden Raum der HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung; oder
- c) Einführen eines Lotdepots in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung und weiteres Einführen oder Einbringen der Einsatzhülse in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung.
- a) arrangement of the at least one solder deposit in the insert sleeve and insertion of the insert sleeve with the at least one solder deposit in the RF conductor receiving bore of the RF conductor receiving element of the connection device; or
- b) inserting the insert sleeve into the HF conductor receiving bore of the HF conductor receiving element of the connecting device and inserting or introducing a solder depot into the space remaining to the insertion opening of the RF conductor receiving bore of the RF conductor receiving element the connection device; or
- c) introducing a solder deposit into the RF conductor receiving bore of the RF conductor receiving element of the connection device and further inserting or inserting the insert sleeve into the HF conductor receiving bore of the RF conductor receiving element of the connection device.
Im Anschluss daran wird der HF-Leiter in die Aufnahmeöffnung der Einsatzhülse oder in die Aufnahmeöffnung der Einsatzhülse und das ringförmige Lotdepot eingeführt.Subsequently, the RF conductor is inserted into the receiving opening of the insert sleeve or into the receiving opening of the insert sleeve and the annular solder depot.
Statt des ersten Verfahrensschritts oder des zweiten Verfahrensschritts können sowohl das Koaxialkabel, als auch die Anschlusseinrichtung in einem dritten Verfahrensschritt entsprechend vorbereitet werden. Dies gelingt durch:
- a) Aufeinanderfolgendes oder gleichzeitiges Einführen der Einsatzhülse in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements der Anschlusseinrichtung und Aufsetzen eines Lotdepots auf den HF-Leiter.
- a) Successive or simultaneous insertion of the insert sleeve in the RF conductor receiving bore of the RF conductor receiving element of the connection device and placing a Lotdepots on the RF conductor.
Im Anschluss daran wird der HF-Leiter in die Aufnahmeöffnung der Einsatzhülse eingeführt.Subsequently, the RF conductor is inserted into the receiving opening of the insert sleeve.
In einem vierten Verfahrensschritt wird das Lotdepot erwärmt bis dieses schmelzflüssig ist. Ein elektrischer Kontakt zwischen dem HF-Leiter und dem HF-Leiter-aufnahmeelement ist daher hergestellt. Besonders vorteilhaft ist, dass einerseits die Einsatzhülse über den HF-Leiter gestülpt werden kann oder andererseits die Einsatzhülse in die HF-Leiteraufnahmebohrung des HF-Leiteraufnahmeelements eingeführt werden kann. Dies erlaubt, dass entweder der HF-Leiter zusammen mit der Einsatzhülse und dem Lotdepot als separates Element vorbereitet werden kann oder dass die Anschlusseinrichtung zusammen mit der Einsatzhülse und optional dem Lotdepot vorbereitet werden kann.In a fourth method step, the solder deposit is heated until it is molten. An electrical contact between the RF conductor and the RF conductor receiving element is therefore made. It is particularly advantageous that on the one hand the insert sleeve can be slipped over the RF conductor or on the other hand, the insert sleeve can be inserted into the RF conductor receiving bore of the RF conductor receiving element. This allows either the RF conductor together with the insert sleeve and the solder deposit to be prepared as a separate element, or the terminal device can be prepared together with the insert sleeve and optionally the solder deposit.

Der Resonator-Innenleiter 18 weist eine Anschlusseinrichtung 2 auf, die ein HF-Leiteraufnahmeelement 10 mit einer HF-Leiteraufnahmebohrung 15 umfasst. In den Resonator-Innenleiter 18 ist eine HF-Leiteraufnahmebohrung 15 eingebracht. Diese stellt in diesem Fall auch das HF-Leiteraufnahmeelement 10 dar. Es kann sein, dass zu einer besseren elektrischen Kontaktierung, die HF-Leiteraufnahmebohrung 15 zusammen mit dem HF-Filter galvanisiert ist.The resonator
Weiterhin umfasst die Anschlussverbindung 1 eine Einsatzhülse 7, die eine Aufnahmeöffnung 8 aufweist, in die der HF-Leiter 4 einführbar oder eingeführt ist.Furthermore, the
Damit der HF-Leiter 4 mit dem Resonator-Innenleiter 18 kontaktierbar ist, weist die Anschlussverbindung 1 noch zumindest ein Lotdepot 9 zur Herstellung einer elektrisch leitfähigen Verbindung auf. Das zumindest eine Lotdepot 9 ist in dem Ausführungsbeispiel aus
Der Außendurchmesser der Einsatzhülse 7 ist bevorzugt derart gewählt, dass die Einsatzhülse 7 kraftschlüssig oder formschlüssig in der HF-Leiteraufnahmebohrung 15 anliegt und nur noch axial, also in Richtung einer einsteckseitigen Einführöffnung 16 oder entgegen dieser einsteckseitigen Einführöffnung 16 bewegt werden. Dies bedeutet, dass die Seiten-Umfangswandung der Einsatzhülse 7, zu der nicht die Stirnseiten zählen, in ihrer Form der Form der Innenseiten-Umfangswandung der HF-Leiteraufnahmebohrung 15 angepasst ist.
Die Einsatzhülse 7 besteht bevorzugt aus einem Kunststoff und ist nicht verformbar. Dadurch ist gewährleistet, dass der Abstand des HF-Leiters 4 zu dem HF-Leiteraufnahmeelement 10 für eine Vielzahl von Anschlussverbindungen 1, die in einer Serie hergestellt werden, konstant ist.The outer diameter of the
The
Der HF-Leiter 4 kann im nächsten Schritt sehr einfach in die Aufnahmeöffnung 8 der Einsatzhülse 7 eingeführt werden. Die Anordnung des zumindest einen Lotdepots 9 bewirkt, dass der HF-Leiter 4 einzig radial mit dem HF-Leiteraufnahmeelement 10 kontaktiert wird.The
Die Anschlusseinrichtung 1 in Form der Steckverbindung 1 weist außerdem die Einsatzhülse 7 auf. Diese Einsatzhülse 7 besitzt die Aufnahmeöffnung 8, die einen Durchmesser hat, der bevorzugt dem Durchmesser des HF-Leiters 4 entspricht oder etwas größer ist. Die Aufnahmeöffnung 8 kann die Einsatzhülse 7, wie in
Die Anschlussverbindung 1 weist ebenfalls zumindest ein Lotdepot 9 auf, welches zur Herstellung einer elektrisch leitfähigen Verbindung zwischen dem HF-Leiter 4 des Koaxialkabels 3 und einem HF-Leiteraufnahmeelement 10 der Anschlusseinrichtung 2 dient. In dem Ausführungsbeispiel aus
Für den Fall, dass der HF-Leiter 4 kein Dielektrikum 5 und keinen Außenleiter 6 umfasst, also nur durch einen einfachen Draht oder eine Litze gebildet ist, kann das Lotdepot 9 beispielsweise durch vercrimpen an dem HF-Leiter 4 befestigt werden. Ein Verrutschen entlang des HF-Leiters 4 ist dann nicht mehr möglich. Der HF-Leiter 4 kann auch kleine Vorsprünge oder Einbuchtungen aufweisen, an denen das zumindest eine Lotdepot gegen Verrutschen gesichert ist.In the event that the
Bei der Einsatzhülse 7 handelt es sich bevorzugt um einen Hohlzylinder. Um eine möglichst niedrige Wärmekapazität zu erreichen, ist die Einsatzhülse 7 bevorzugt aus einem Kunststoff gefertigt. Die Einsatzhülse 7 kann beispielsweise in einem Spritzgussverfahren hergestellt werden. Das HF-Leiteraufnahmeelement 10 besteht dagegen aus einem Metall.The
Die Anschlusseinrichtung 2 in Form eines Steckverbinders 2 weist außerdem eine Außenleiterbuchse 12 auf, die zur Aufnahme des Koaxialkabels 3 dient. Die Außenleiterbuchse 12 weist hierzu eine Kabelaufnahmeöffnung 13 auf. Die Außenleiterbuchse 12 ist bevorzugt aus einem leitfähigen Material gebildet oder mit einem solchen überzogen und besitzt einen Außenleiterkontaktierungsabschnitt 14, mit dem ein elektrisch leitfähiger Kontakt mit dem Außenleiter 6 des aufzunehmenden Koaxialkabels 3 hergestellt wird. Die Kabelaufnahmeöffnung 13 weist einen Durchmesser auf, der bevorzugt dem Durchmesser des Koaxialkabels 3 bis zu seinem Außenleiter 6 entspricht. Eine äußere Schutzummantelung des Koaxialkabels 3 ist bevorzugt im Bereich der Kabelaufnahmeöffnung 13 abisoliert.The
Das HF-Leiteraufnahmeelement 10 verfügt über eine HF-Leiteraufnahmebohrung 15. Die HF-Leiteraufnahmebohrung 15 dient zur Aufnahme des HF-Leiters 4 des Koaxialkabels 3, wobei das HF-Leiteraufnahmeelement 10 bevorzugt zentriert innerhalb der Außenleiterbuchse 12 angeordnet ist.The HF
Der Durchmesser der HF-Leiteraufnahmebohrung 15 ist derart gewählt, dass dieser dem Außendurchmesser der Einsatzhülse 7 entspricht oder etwas größer ist.The diameter of the RF conductor receiving bore 15 is selected such that it corresponds to the outer diameter of the
Die Einsatzhülse 7 kann über eine einsteckseitige Einführöffnung 16 in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelement 10 eingeführt werden. Der Durchmesser der HF-Leiteraufnahmebohrung 15 ist bevorzugt konstant. Er verändert, insbesondere vergrößert er sich vorzugsweise nicht über seine axiale Länge.The
Der HF-Leiter 4 des Koaxialkabels 3 erstreckt sich in der Aufnahmeöffnung 8 der Einsatzhülse 7 nur über einen Teil der Länge der Aufnahmeöffnung 8, also nur über einen Teil der Länge der Einsatzhülse 7. Es wäre allerdings auch möglich, dass sich der HF-Leiter 4 des Koaxialkabels 3 über die gesamte Länge der Aufnahmeöffnung 8 oder sogar ein wenig über diese hinaus erstreckt.The
Innerhalb von
Im Weiteren wird noch der Außenleiterkontaktierungsabschnitt 14 der Außenleiterbuchse 12 mit dem Außenleiter 6 des aufgenommenen Koaxialkabels 3 elektrisch leitend verbunden. Dies kann beispielsweise durch Verpressen und/oder Vercrimpen geschehen. Bevorzugt ist der elektrische Kontakt zwischen dem Außenleiter 6 und dem Außenleiterkontaktierungsabschnitt 14 von einer zusätzlichen, bevorzugt rein mechanischen Fixierung getrennt.Furthermore, the outer
Der Außenleiter 6 des Koaxialkabels 3 liegt in diesem Fall auf einer Auflageschulter 20 auf. Es ist allerdings auch möglich, dass ein weiteres Dielektrikum zwischen einer Stirnseite des Außenleiters 6 des Koaxialkabels 3 und der Auflageschulter 20 der Außenleiterbuchse 12 angeordnet ist, so dass ein elektrischer Kontakt zwischen der Stirnseite des Außenleiters 6 des Koaxialkabels 3 und der Auflageschulter 20 der Außenleiterbuchse 12 verhindert wird. Gerade solche stirnseitigen Kontakte stellen sich hinsichtlich einer Reproduzierbarkeit des elektrischen Kontakts als problematisch dar. Daher ist es vorteilhaft, wenn der Außenleiter 6 einzig mit einer radialen Komponente elektrisch kontaktiert wird.The
Anschlusseinrichtung 2 kann im Anschluss daran das zumindest eine Lotdepot 9, bei welchem es sich bevorzugt um ein ringförmiges Lotdepot 9 handelt, in den zur Einführöffnung 16 hin verbleibenden Raum 30 der HF-Leiteraufnahmebohrung 15 eingeführt werden. Dieser Sachverhalt ist in
Der HF-Leiter 4 des aufzunehmenden Koaxialkabels 3 kann sowohl durch das Lotdepot 9, als auch durch die Aufnahmeöffnung 8 der Einsatzhülse 7 geführt werden.The
Das Lotdepot 9, welches in diesem Fall bevorzugt eine zähflüssige Konsistenz hat, wird in den zumindest einen Aufnahmekanal 40 eingebracht. Im Anschluss daran kann die Einsatzhülse 7 auf den HF-Leiter 4 des Koaxialkabels 3 aufgesetzt und mit diesem direkt in die HF-Leiteraufnahmebohrung 15 eingesetzt werden. Es ist auch möglich, dass der zumindest eine Aufnahmekanal 40 erst dann mit dem Lotdepot 9 befüllt wird, wenn die Einsatzhülse 7 auf dem HF-Leiter 4 des Koaxialkabels 3 aufgesetzt ist. In diesem Fall ist sichergestellt, dass ausschließlich nicht gealtertes Lot zur Herstellung des Lotdepots 9 verwendet wird.The
Das Lotdepot 9 kann ebenfalls bevorzugt auf der halben Länge der Einsatzhülse 7 in diese eingebracht werden. Bei mehreren Lotdepots 9 sind diese bevorzugt symmetrisch zu einer gedachten Geraden angeordnet, die quer durch den Längsschnitt durch die Mitte der Einsatzhülse 7 verläuft. Dadurch ist sichergestellt, dass die Lotdepots 9 den HF-Leiter 4 stets an der gleichen Stelle mit dem HF-Leiteraufnahmeelement 10 kontaktieren und zwar unabhängig davon in welcher Richtung die Einsatzhülse 7 in die HF-Leiteraufnahmebohrung 15 eingeführt wird.The
Die Einsatzhülse 7 aus
Es ist auch möglich, dass die Einsatzhülse 7 an ihrem Umfang zumindest ein Kodierelement aufweist, wodurch die Einsatzhülse 7 nur an einer bestimmten Position in das HF-Leiteraufnahmeelement 10, also in die HF-Leiteraufnahmebohrung 15 eingeführt werden kann und verdrehsicher innerhalb dieser bevorzugt anschlagsbegrenzt gelagert ist.It is also possible that the
Die Aufnahmekanäle 40 sind in den
Innerhalb von
Das Lotdepot 9 weist bevorzugt die Form eines teilweise offenen oder geschlossenen Rings auf. Der Außendurchmesser des bevorzugt ringförmigen Lotdepots 9 ist vorzugsweise gleich groß wie der Außendurchmesser des Dielektrikums 5. Es kann auch möglich sein, dass der Teil des Dielektrikums 5, der in die HF-Leiteraufnahmebohrung 15 eingeführt ist, einen kleineren Außendurchmesser aufweist, als der Teil des Dielektrikums 5, der noch von dem Außenleiter 6 umgeben ist.The
Die Ausführungsbeispiele der
Das zumindest eine Anpasselement 70 ist zwischen dem Außenleiterkontaktierungsabschnitt 14 und dem HF-Leiteraufnahmeelement 10 angeordnet. Es hat bevorzugt die Form eines Hohlzylinders, wobei der HF-Leiter 4 des Koaxialkabels 3 durch dieses hindurch geführt ist. Das Anpasselement 70 umgibt den HF-Leiter 4 vorzugsweise radial. Es ist allerdings auch möglich, dass das zumindest eine Anpasselement 70 den HF-Leiter 4 nicht an seinem gesamten Umfang, also im Bereich von 360° umgibt, sondern nur in einem bestimmten Abschnitt.The at least one matching
Das Anpasselement 70 kann beispielsweise vor der Montage der Anschlusseinrichtung 2 eingesetzt werden oder alternativ über die Kabelaufnahmeöffnung 13 eingeführt werden. In letzterem Fall weist die Außenleiterbuchse 12 allerdings keine Auflageschulter 20 auf.The
Die
Der HF-Leiter 4 ist außerdem von einem Dielektrikum 5 und einem Außenleiter 6 umgeben. Der HF-Leiter 4 und das Dielektrikum 5 ragen durch die Gehäusewand 50 in den HF-Filter hinein. Der Außenleiter 6 endet mitten in die Gehäusewand 50 und steht zumindest mit seiner Stirnseite in elektrischem Kontakt mit dieser. Es ist auch möglich, dass der Außenleiter 6 zusätzlich mit einem Teil seiner Seitenumfangswandung in elektrischem Kontakt mit der Gehäusewand 50 steht. Das Dielektrikum 5 liegt mit seiner Stirnseite an dem Lotdepot 9 an.The
Die
Im Gegensatz zu dem Ausführungsbeispiel aus
In dem ersten Verfahrensschritt S1 muss der aufzunehmende HF-Leiter 4 entsprechend vorbereitet werden. Dies kann durch verschiedene Schritte geschehen. Möglich ist beispielsweise ein aufeinanderfolgendes oder gleichzeitiges Aufsetzen eines vorzugsweise ringförmigen Lotdepots 9 und der Einsatzhülse 7 auf den HF-Leiter 4. Das bevorzugt ringförmige Lotdepot 9 befindet sich dann zwischen der Stirnseite der Einsatzhülse 7 und der Stirnseite 11 des Dielektrikums 5 des Koaxialkabels 3. Im Gegensatz dazu kann auch ein aufeinanderfolgendes oder gleichzeitiges Aufsetzen der Einsatzhülse 7 und des vorzugsweise ringförmigen Lotdepots 9 auf den HF-Leiter 4. Das Lotdepot 9 ist daher am Ende des HF-Leiters 4 angeordnet. Der HF-Leiter 4 erstreckt sich durch die Einsatzhülse 7 und endet innerhalb des Lotdepots 9. Es ist auch möglich, dass die Einsatzhülse 7 auf den HF-Leiter 4 aufgesetzt wird, wobei das zumindest eine Lotdepot 9 bereits an oder in der Einsatzhülse 7 angeordnet ist. In diesem Fall könnte die Einsatzhülse 7 beispielsweise über Aufnahmekanäle 40 verfügen. Im Weiteren wäre es auch möglich, dass die Einsatzhülse 7 auf den HF-Leiter 4 aufgesetzt wird und dass im Anschluss daran zumindest ein Lotdepot 9 in der Einsatzhülse 7 angeordnet wird. Im Anschluss daran kann der aufzunehmende HF-Leiter 4 zusammen mit der Einsatzhülse 7 und dem zumindest einen Lotdepot 9 in das HF-Leiteraufnahmeelement 10, also in die HF-Leiteraufnahmebohrung 15 der Anschlusseinrichtung 2 eingeführt werden.In the first method step S 1 , the
Alternativ zu dem Verfahrensschritt S1 könnte auch der Verfahrensschritt S2 ausgeführt werden. Innerhalb des Verfahrensschritts S2 wird stattdessen die Anschlusseinrichtung 2 entsprechend vorbereitet. Dies gelingt beispielsweise dadurch, dass das zumindest eine Lotdepot 9 in der Einsatzhülse 7 angeordnet wird, und dass im Anschluss daran die Einsatzhülse 7 mit dem zumindest einen Lotdepot 9 in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt wird. Es wäre auch möglich, dass die Einsatzhülse 7 in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt wird, und dass im Anschluss daran ein vorzugsweise ringförmiges Lotdepot 9 in den zur HF-Leiteraufnahmebohrung 15 hin verbleibenden Raum 30 der HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt wird. Es wäre auch möglich, dass das vorzugsweise ringförmige Lotdepot 9 in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt wird und dass weiterhin die Einsatzhülse 7 in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt oder eingebracht wird. Weiterhin müsste der HF-Leiter 4 des aufzunehmenden Koaxialkabels 3 in die Aufnahmeöffnung 8 der Einsatzhülse 7 oder in die Aufnahmeöffnung 8 der Einsatzhülse 7 und in das ringförmige Lotdepot 9 eingeführt werden.As an alternative to method step S 1 , method step S 2 could also be carried out. Within the method step S 2 , the connection device 2 is instead prepared accordingly. This succeeds, for example in that the at least one
Alternativ zu den Verfahrensschritten S1 und S2 könnte auch der Verfahrensschritt S3 ausgeführt werden. Innerhalb des Verfahrensschritts S3 werden sowohl der HF-Leiter 4, als auch die Anschlusseinrichtung 2 vorbereitet. Die Eisatzhülse 7 wird in die HF-Leiteraufnahmebohrung 15 des HF-Leiteraufnahmeelements 10 der Anschlusseinrichtung 2 eingeführt und gleichzeitig oder abwechselnd dazu wird das vorzugsweise ringförmige Lotdepot 9 auf den HF-Leiter 4 aufgesetzt. Weiterhin wird der HF-Leiter 4 in die Aufnahmeöffnung 8 der Einsatzhülse 7 eingeführt.As an alternative to the method steps S 1 and S 2 , the method step S 3 could also be carried out. Within method step S 3 , both the
Im Folgenden, also nach einem der Verfahrensschritte S1, S2, oder S3 wird der Verfahrensschritt S4 ausgeführt. Innerhalb des Verfahrensschritts S4 wird das Lotdepot 9 erwärmt, bis dieses schmelzflüssig ist und damit den HF-Leiter 4 mit dem HF-Leiteraufnahmeelement 10 elektrisch leitend verbindet. Innerhalb des Verfahrensschritts S4 kann eine Induktionsschleife verwendet werden, die das Lotdepot 9 zum Schmelzen bringt.In the following, ie after one of the method steps S 1 , S 2 , or S 3 , the method step S 4 is carried out. Within the process step S 4 , the
Für den Fall, dass der HF-Leiter 4 noch von einem Dielektrikum 5 und optional noch von einem Außenleiter 6 umgeben ist, er also den Innenleiter 4 eines Koaxialkabels darstellt, muss für dem ersten oder zweiten oder dritten Verfahrensschritt S1, S2 oder S3 noch der Verfahrensschritt S0 ausgeführt werden. In diesem Verfahrensschritt S0 wird der HF-Leiter 4 des aufzunehmenden Koaxialkabels 3 freigelegt. Dies gelingt am besten durch entsprechende Abisolierwerkzeuge. Der HF-Leiter 4 steht daher über das Dielektrikum 5 und den optionalen Außenleiter 6 hervor.In the event that the
In einem weiteren Verfahrensschritt kann der Außenleiterkontaktierungsabschnitt 14 der Außenleiterbuchse 12 mit dem Außenleiter 6 des aufgenommenen Koaxialkabels 3 verpresst und/oder vercrimpt werden, so dass auch ein elektrischer Kontakt zwischen dem Außenleiter 6 des Koaxialkabels 3 und der Außenleiterbuchse 12 hergestellt ist.In a further method step, the outer
Unter dem Wortlaut, dass ein Lotdepot 9 "in" die Einsatzhülse 7 eingeführt ist, wird verstanden, dass die Einsatzhülse 7 zumindest einen Aufnahmekanal 40 oder dergleichen aufweist, in dem das Lotdepot 9 angeordnet ist.Under the wording that a
