Description

Stützscheibe zum Abstützen von Hochfrequenz(HF)-Komponenten Support disc for supporting high-frequency (HF) components
Die Erfindung bezieht sich auf eine Stützscheibe zum Abstützen von Hochfre- quenz(HF)-Komponenten, insbesondere in HF-Koaxialkabeln oder Koaxialsteckver- bindern, nach dem Oberbegriff des Anspruchs 1.The invention relates to a support disk for supporting high-frequency (HF) components, in particular in HF coaxial cables or coaxial connectors, according to the preamble of claim 1.
Ständig steigende Anforderungen an die technischen Parameter von HF- und Mikrowellenkomponenten speziell für die Präzisionsmesstechnik setzen eine hohe Qualität der einzelnen Baugruppen und damit auch der Stützscheiben voraus. Insbesondere Reflektions- und Transmissionseigenschaften von Abschlusswiderständen, Adaptern, Dämpfungsgliedern oder dergleichen hängen sehr stark von den koaxialen Stützelementen, den sogenannten Stützscheiben, ab.Constantly increasing demands on the technical parameters of HF and microwave components especially for precision metrology require a high quality of the individual assemblies and thus also of the supporting disks. In particular, reflection and transmission properties of terminators, adapters, attenuators or the like are very much dependent on the coaxial support elements, the so-called support disks.
Aus der Praxis sind verschiedene Arten von Stützscheiben bekannt. Eine dieser Stützscheiben hat acht, den Stützkörper der Stützscheibe vollständig durchdringende Längsbohrungen. Zum Herstellen einer solchen Stützscheibe sind zahlreiche Fertigungsschritte erforderlich, so dass die Herstellungskosten einer solchen Scheibe relativ hoch sind. Eine andere, aus der Praxis bekannte Stützscheibe ist als Spritzteil mit relativ komplizierter Geometrie hergestellt, wobei der Stützkörper in einen äußeren Haltering eingepresst ist. Dieser Stützkörper hat kreuzförmige Rippen, deren Querschnitt etwa V- bzw. U-förmig ausgebildet und damit in der Art eines Fächers aufgebaut ist. Auch diese Stützscheibe ist in der Herstellung relativ aufwändig und damit teuer. Sie weist gute elektrische Eigenschaften, jedoch ein nachteiliges Temperaturverhalten auf, da sie lediglich bis zu einer Temperatur von maximal etwa 85°C eingesetzt werden kann.From practice, various types of support discs are known. One of these support disks has eight, the support body of the support disk completely penetrating longitudinal bores. For producing such a support disk numerous manufacturing steps are required, so that the manufacturing cost of such a disc are relatively high. Another known from practice support disk is made as a molded part with relatively complicated geometry, wherein the support body is pressed into an outer retaining ring. This support body has cross-shaped ribs whose cross-section is approximately V- or U-shaped and thus in the manner of a fan is constructed. These support disk is relatively expensive to manufacture and therefore expensive. It has good electrical properties, but a disadvantageous temperature behavior, since it can only be used up to a temperature of about 85 ° C maximum.
Der Erfindung liegt die Aufgabe zugrunde, eine Stützscheibe der eingangs erwähnten Art zu schaffen, die einerseits wirtschaftlich herstellbar und andererseits hinsichtlich der elektrischen Eigenschaften verbessert ist.The invention has for its object to provide a support plate of the type mentioned, which is on the one hand improved economically and on the other hand improved in electrical properties.
Diese Aufgabe wird erfindungsgemäß durch eine Stützscheibe der o.g. Art mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a support disk of o.g. Art solved with the features of claim 1.
Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.Advantageous developments are the subject of the dependent claims.
Erfindungsgemäß hat der Stützkörper neben seiner Längsbohrung zusätzlich wenigstens eine Querbohrung. Diese wenigstens eine Querbohrung bewirkt eine außergewöhnliche Verbesserung der Hochfrequenzeigenschaften. Ein optimaler Wellenwiderstand der Stützscheibe über den gesamten Frequenzbereich ermöglicht eine sehr gute Anpassung an die Impedanz der abzustützenden HF-Komponente. Gleich- zeitig weist die erfindungsgemäße Stützscheibe auch eine besonders gute mechanische Festigkeit auf, da genügend Material für eine dauerhafte, flächige Abstützung zur Verfügung steht. Die erfindungsgemäße Stützscheibe wird daher sowohl den mechanischen als auch den elektrischen Anforderungen in vollem Umfang gerecht.According to the invention, the support body in addition to its longitudinal bore additionally at least one transverse bore. This at least one transverse bore causes an extraordinary improvement in the high-frequency characteristics. An optimal characteristic impedance of the support disk over the entire frequency range allows a very good adaptation to the impedance of the RF component to be supported. At the same time, the support disk according to the invention also has a particularly good mechanical strength, since sufficient material is available for permanent, planar support. The support disk according to the invention therefore fully meets both the mechanical and the electrical requirements.
Vorteilhafterweise ist die Längsbohrung zentrisch im Stützkörper angeordnet und durchdringt die wenigstens eine Querbohrung den Stützkörper und dessen Längsbohrung vollständig. Dadurch lassen sich zum einen eine gute mechanische Festigkeit, ein relativ günstiger Preis bei gleichzeitig guten elektrischen Eigenschaften erzielen. Letztere ermöglichen eine relativ geringe Reflektion sowie eine hohe Trans- mission der elektrischen Signale und damit eine hohe Leistung bei der Übertragung dieser Signale von einer HF-Komponente an eine andere. Gemäß einer vorteilhaften Weiterbildung der Erfindung ist die wenigstens eine Querbohrung als Sackbohrung ausgebildet. Damit ist es möglich, die elektrischen Eigenschaften der Stützscheibe exakt an die gewünschten Werte anzupassen. Es ist fer- ner möglich, eine oder mehrere durchgehende Querbohrungen mit einer oder mehreren quer verlaufenden Sackbohrungen an derselben Stützscheibe miteinander zu kombinieren.Advantageously, the longitudinal bore is arranged centrally in the support body and penetrates the at least one transverse bore the support body and its longitudinal bore completely. As a result, on the one hand good mechanical strength, a relatively low price and good electrical properties can be achieved. The latter allow a relatively low reflection as well as a high transmission of the electrical signals and thus a high power in the transmission of these signals from one RF component to another. According to an advantageous embodiment of the invention, the at least one transverse bore is formed as a blind bore. This makes it possible to adapt the electrical properties of the support disk exactly to the desired values. It is also possible to combine one or more continuous transverse bores with one or more transverse blind bores on the same supporting disc.
Gemäß einer anderen Weiterbildung der Erfindung sind zwei Querbohrungen vorge- sehen, welche vorzugsweise um 90° zueinander versetzt angeordnet sind. Eine solche Stützscheibe ist relativ einfach zu fertigen und aufgrund ihrer guten mechanischen und elektrischen Eigenschaften besonders vorteilhaft einsetzbar.According to another embodiment of the invention, two transverse bores are provided, which are preferably offset by 90 ° to each other. Such a support disk is relatively easy to manufacture and can be used particularly advantageously due to their good mechanical and electrical properties.
Vorteilhafterweise weist der Stützkörper auf seiner Vorder- und Rückseite eine Ringnut auf. Diese dient vornehmlich dazu, einen elektrischen Feinabgleich der e- lektrischen Parameter der Stützscheibe auf einfache Weise zu ermöglichen.Advantageously, the support body has an annular groove on its front and rear sides. This serves primarily to allow a fine electrical adjustment of the electrical parameters of the support disk in a simple manner.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist der Stützkörper umfangs- seitig von einem Haltering umgeben, in den der Stützkörper vorzugsweise einge- presst ist. Dadurch ist der Stützkörper im Haltering sicher befestigt, so dass die gesamte Stützscheibe in Längsrichtung dicht ausgebildet sein kann und beispielsweise bei entsprechender Einfärbung den Innenaufbau der betreffenden HF-Komponente zusätzlich vor einfallendem Licht schützen kann. Der erfindungsgemäße Stützkörper hat beispielsweise auf seiner umfangsseitigen Mantelfläche genügend Material, um die mechanische Festigkeit am Innendurchmesser des Halterings, auch Außenleiter- ring genannt, zu gewährleisten. Eine solche Stützscheibe gewährleistet daher neben guten elektrischen Eigenschaften auch eine gute mechanische Stabilität, was sich positiv auf die Lebensdauer der Stützscheibe und damit auf die gesamte HF- Komponente auswirkt.According to a preferred embodiment of the invention, the support body is peripherally surrounded by a retaining ring, in which the support body is preferably pressed. As a result, the support body is securely fastened in the retaining ring, so that the entire support disk can be designed to be tight in the longitudinal direction and, for example, with appropriate coloring the inner structure of the relevant RF component can additionally protect against incident light. The support body according to the invention has, for example, on its peripheral surface enough material to ensure the mechanical strength at the inner diameter of the retaining ring, also called Außenleiter- ring. Such a support disk therefore ensures not only good electrical properties but also good mechanical stability, which has a positive effect on the service life of the support disk and thus on the entire HF component.
Gemäß einer anderen Weiterbildung der Erfindung ist in die Längsbohrung des Stützkörpers ein Innenring eingesetzt, welcher von der wenigstens einen Querboh- rung durchdrungen oder nicht durchdrungen ist. Beide Varianten sind getrennt voneinander oder in Kombination miteinander möglich. Ein derartiger Innenring lässt sich speziell an den Durchmesser des aufzunehmenden Innenleiters beispielsweise eines HF-Koaxialkabels und an die gewünschten elektrischen Eigenschaften, die die Stϋtz- scheibe aufweisen soll, anpassen. Der Innenleiter kann flächig an dem Innenring anliegen und daher besonders gut abgestützt sein. Ein Wackeln des Innenleiters an der Stützscheibe ist damit sicher verhindert.According to another embodiment of the invention, an inner ring is inserted into the longitudinal bore of the support body, which of the at least one transverse penetrated or not penetrated. Both variants are possible separately or in combination with each other. Such an inner ring can be adapted to the diameter of the male inner conductor, for example, of an RF coaxial cable, and to the desired electrical properties that the contact disk is to have. The inner conductor can lie flat against the inner ring and therefore be particularly well supported. A wobble of the inner conductor on the support disk is thus reliably prevented.
Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist der Stützkörper aus einem dielektrischen Material, vorzugsweise Polystyrol, besonders bevorzugt aus einem strahlenvernetzten Polystyrol, gefertigt. Eine solche Stützscheibe weist auch ein besonders gutes Temperaturverhalten und damit eine hohe Leistungsfähigkeit auf. Eine derartige Scheibe ist daher besonders vorteilhaft bei höheren Leistungen einsetzbar. Sie ist für Anwendungen in einem weiten Temperaturbereich beson- ders geeignet.According to another preferred development of the invention, the support body is made of a dielectric material, preferably polystyrene, particularly preferably of a radiation-crosslinked polystyrene. Such a support disk also has a particularly good temperature behavior and thus high performance. Such a disk is therefore particularly advantageous for higher powers. It is particularly suitable for applications in a wide temperature range.
Vorteilhafterweise beträgt das Verhältnis von Innendurchmesser der wenigstens einen Querbohrung zur Dicke des Stützkörpers etwa 0,25 bis 0,6, bevorzugt 0,46 bis 0,47. Mit einem derartigen Aufbau ist die erfindungsgemäße Stützscheibe einfach zu fertigen und zu montieren. Mit ihr lassen sich gute elektrische und thermische Eigenschaften realisieren, so dass eine solche Stützscheibe auch bei höheren Frequenzen und Leistungen zum Einsatz kommen kann.Advantageously, the ratio of the inner diameter of the at least one transverse bore to the thickness of the support body is about 0.25 to 0.6, preferably 0.46 to 0.47. With such a structure, the support disk according to the invention is easy to manufacture and assemble. With her good electrical and thermal properties can be realized, so that such a support disk can be used even at higher frequencies and powers.

It is possible to provide both continuous and bag-shaped transverse bores on one and the same support disk.
Wie in den Fig. 1 bis 5 angedeutet, sind gemäß einer bevorzugten Ausführungsform der Erfindung zwei Querbohrungen 4, 10 vorgesehen, welche vorzugsweise um 90° zueinander versetzt angeordnet sind.

Ein Stützkörper aus einem derartigen Material weist gute dielektrische Eigenschaften auf, die mit denen von Po- lyethylen und Polytetrafluorethylen vergleichbar sind. Das Verhältnis von Innendurchmesser 17 der wenigstens einen Querbohrung 4 zur Dicke 20 des Stützkörpers 2 beträgt etwa 0,25 bis 0,6, bevorzugt 0,46 bis 0,47.According to another, preferred embodiment of the invention, the support body 2 is made of a dielectric material, preferably polystyrene, more preferably of a radiation-crosslinked polystyrene. A support body of such material has good dielectric properties comparable to those of polyethylene and polytetrafluoroethylene. The ratio of inner diameter 17 of the at least one transverse bore 4 to the thickness 20 of the support body 2 is about 0.25 to 0.6, preferably 0.46 to 0.47.
In Fig. 4 ist eine Draufsicht auf den Stützkörper 2 der Stützscheibe 1 gezeigt, deren 5 Schnitt V-V in Fig. 5 verdeutlicht ist. Ferner zeigt Fig. 6 eine Draufsicht auf den Haltering 16, deren Schnitt VII-VII in Fig. 7 dargestellt ist.In Fig. 4 is a plan view of the support body 2 of the support plate 1 is shown, the 5 section V-V is illustrated in Fig. 5. Further, Fig. 6 shows a plan view of the retaining ring 16, the section VII-VII is shown in Fig. 7.
Wie zuvor erwähnt, sind die Abmessungen von Stützkörper 2 und Haltering 16 derart gewählt, dass der in den Haltering eingepresste Stützkörper in dem Haltering ortsfest D gehalten ist und somit eine Relativbewegung zwischen Stützkörper und Haltering ausgeschlossen ist.As previously mentioned, the dimensions of support body 2 and retaining ring 16 are chosen such that the pressed-in support ring in the retaining ring is held in a stationary D and thus a relative movement between the support body and retaining ring is excluded.
Miteinander fluchtende Abschnitte von Querbohrungen können in einem oder in mehreren Arbeitsgängen in den Stützkörper gebohrt werden, im ersten Fall, in dem durch 5 den gesamten Stützkörper hindurchgebohrt wird, im zweiten Fall, in dem zwei, den Stützkörper jeweils nur teilweise durchdringende Querbohrungen vorgesehen werden.Co-aligned portions of transverse bores may be drilled in one or more operations in the support body, in the first case in which the entire support body is drilled through 5, in the second case in which two, the support body are only partially penetrating transverse bores are provided.
Damit ist eine Stützscheibe geschaffen, die äußerst wirtschaftlich herstellbar und be- d sonders vorteilhaft einsetzbar ist. In order for a support disk is created, which is extremely economical to produce and be particularly advantageous used.
