- Galvanic contacts between high-frequency components are, for example, contacts between dipole and reflector or other components and reflector, a cover on a housing or even the contacts of high-frequency switches.
- galvanic contacts are made by contacting a fixed element by means of two movable conductors.
- the shape of the solid element determines the counter-shape of the other conductors.

- Another alternative is in the US 3,226,515 shown.
- the contact between the conductors for switching over a spherical switching element is achieved, which can be moved by means of a switch handle attached thereto and establishes the contact between two conductors.
- a switch handle attached thereto and establishes the contact between two conductors.
- a spring element is mounted, through which the switching element can be pressed over the middle conductor, so that it can make electrical contact between the middle and one of the outer conductor.
- a spherical switching element and spherical conductor are used here for contacting, since less force must be used to push the switching element over the middle conductor.
- an arrangement for the electrical contacting of electrically conductive elements, comprising a first electrically conductive element on at least a portion thereof, at least a second electrically conductive element on at least a portion thereof for electrically contacting the first element, comprising a contact region on at least one end region thereof, wherein the contact region has a radius at least at predetermined contact points, and wherein the first electrically conductive element has at least one region which is adapted to receive at least a part of the contact region of the second electrically conductive element such that an electrical contact between the first electrically conductive element and the contact points of the second electrically conductive element is formed.
- the first and the second electrically conductive element are designed as high-frequency components, which is to be contacted with each other. Such components are usually carried out by means of conductive shielding housing.
- the first electrically conductive element is designed as a high-frequency component and the second electrically conductive element as a contact element which comprises an electrical conductor, at the distal end region of which the contact region is arranged.
- the first and / or the second electrically conductive element as a reflector sheet, a housing, a filter housing, a bias T, a heat sink, a switch or switch contacts, a dipole or high-frequency conductor is formed.
- any electrically conductive elements can be electrically contacted with each other, for example, high-frequency components with high-frequency components, high-frequency components with electrical conductors, electrical conductors with other electrical conductors.
- the region of the first electrically conductive element for receiving the second electrically conductive element is a recess in the first electrically conductive element.
- the region of the first electrically conductive element for receiving the second electrically conductive element comprises at least two contact legs, which are arranged on the first electrically conductive element.

- the second electrically conductive element and / or the region of the first electrically conductive element for receiving the second electrically conductive element has beveled edges at predetermined contact regions.
- the region of the first electrically conductive element for receiving the second electrically conductive element has a radius at least at predetermined contact regions. Providing beveled edges or a radius becomes a larger tolerance allowed during assembly, since the component can be mounted with a tilt or slightly tilted without touching the first electrically conductive element at a further location and thus to produce an undesirable electrical contact.
- the area below the contact points, ie between the contact points and the surface of the second electrically conductive element is not critical, ie, a contact between the first and second electrically conductive element can take place, since the currents flow only over the surface, ie over the Contact points to the leader. In this area it is important that no further or uneven contacting takes place.
- the contact element for electrically contacting the high-frequency component with a second high-frequency component is set up and the electrical conductor of the contact element has a second contact area at its other distal end, wherein the second contact region has a radius at least at predetermined second contact points, and wherein the second high-frequency component has at least one region as described above.

- the region is a recess in the first element or comprises at least two contact legs, which are arranged on the first element, or comprises three contact legs, which are arranged on the first element, or as a bulge in the first element first element is formed.

- the first and / or the second element as a reflector sheet, a housing or other component such as a filter housing, a bias T, a heat sink, a switch or switch contacts, a dipole or high-frequency conductor of each type is formed and the second
- the element and / or the region of the first element have beveled edges at predetermined contact regions or at least at predetermined contact regions have a radius.
- Intermodulation occur, for example, at close to each other transmission frequencies with high power, eg in transmitters in telecommunications, and produce unwanted spurious frequencies.
- Such disturbing frequencies occur not only in large broadcasting systems, but also inside the antenna due to, for example, poor metal to metal joints or uneven contact surfaces. Uneven contact surfaces are very difficult to avoid, since when pressing two surfaces very high forces must be used to create a solid connection. If the two pressed surfaces are not absolutely flat, it is very likely that the contact between the surfaces is not uniform over the entire surface. Thus, unwanted intermodulation can arise. This problem is solved by the arrangement according to the invention.
- High-frequency element is to be understood as meaning high-frequency components such as reflector plates, a housing or other components such as filter housings, bias T, heat dissipators, switches or switch contacts, dipole, high-frequency conductors of any type, etc.
- Inner conductive regions, outer conductors or any type of conductive regions of an element to be contacted are possible as conductive regions, depending on which components are contacted. Examples of different contacts are in FIGS. 1 a and 6 are shown.
- FIG. 1 a is a reflector sheet contacted via a Maiséement with an electrical conductor, wherein in FIG. 6 the electrically conductive region is a region of a dipole that acts as an electrical conductor.
- FIG. 1a shows a sectional view of an arrangement according to an embodiment of the present invention. Shown is a first high-frequency element 10, which is formed as an electrical conductor, and electrically with a second, designed as a high-frequency component high-frequency element 2 such as a reflector plate, a housing or other components such as filter housing, bias T, heat sink, switch or switch contacts , Dipole, high frequency conductors of any kind, etc. should be contacted.
- the high-frequency component 2 has a region 21, which can receive a contact element 1. This area is in FIG. 1a shown as a recess in the high frequency component 2 and has beveled edges. In this region 21 of the high-frequency component 2, a contact element 1, which has an electrical conductor 10 and a contact region 11, are received. Thus, an electrical contact between the high-frequency component 2 and the component to be connected by the contact element 1 is produced.
- the contact area 11 is shown as a sphere.
- the spherical geometry or a radius at the contact regions 11 ensures that the contact regions 11 between the high-frequency component 2 and the contact element 1 form a defined punctiform contact surface.
- the spherical geometry also allows the same contact geometry even with tolerances and position inaccuracies, so that a permanently good intermodulation-free electrical contact and a very good reproducibility can be ensured without having to apply correspondingly high contact forces.
- the contact area 11 is shown as a complete sphere.
- FIG. 1b The compensation of tolerances and positional inaccuracies is reinforced by the bevelled edges of the high-frequency component 2.
- the funnel-shaped recess 21 allows the contact element 1 to perform an intermodulation-free electrical contact even in an oblique position make the punctiform contact surfaces 12, without making an unwanted contact with another area on the high-frequency component 2.
- Figures 2 and 3 each show a sectional view of an arrangement according to another embodiment of the present invention.
- the region 21 of the high-frequency component 2 is designed as a trough and has rounded edges at the contact points 12.
- the contact region 11 of the contact element 1, which is formed in both figures as a dipole, in both figures only at the contact points 12 has a spherical geometry. This is sufficient for intermodulation-free contact since electrical currents flow only over the contact points or surfaces. Thus, it is sufficient to provide at the contact points 12, the spherical geometry or the radius so that position inaccuracies can be compensated.
- the residual shape of the contact region 11 can basically be chosen as desired as long as the contacting at the contact points 12 is ensured by the current flow properties.
- FIG Figures 2 and 3 Two examples of possible shapes of the contact region 11 within the recess 21 in the high-frequency component 2 are shown in FIG Figures 2 and 3 shown.
- a screw 100 is inserted through the underside of the high-frequency component 2 into the contact region 11 of the contact element 1 for fastening the contact element 1 with the high-frequency component 2.
- the screw 100 serves only to reinforce the attachment of the contact element 1 and can also be replaced by other fasteners or not be present at all.
- the contact area 11 is not formed to the bottom of the recess 21. This allows a higher tolerance during the production of the recess 21.
- the screw 100 stabilizes the contact between the high-frequency component 2 and the contact element 1.
- the contact region 11 of the contact element 1 is formed as far as the bottom of the recess 21, so that a connection which is more stable by the contact element 1 alone is formed here. Further, electrical is separated from the mechanical function and the leverage of the fastened component is introduced to the block screw, the electrically important contact point 12 remains unloaded, so that acting forces do not act on the electrical contact point, but are always derived on the non-critical mechanical support. In this embodiment, care must be taken that the contact is ensured at the contact points 12. This can be ensured by tight screwing with the screw 100 or compensated to a small extent.
- the contact region 11 is not shown as a complete sphere, but instead has a spherical geometry or a radius at the contact region 11 at predetermined contact points 12 between the high-frequency component 2 and the contact region 11.
- FIGS. 4a and 4b each show a sectional view of an arrangement according to another embodiment of the present invention.
- FIG. 4a shows the same contact element 1 as in FIG. 1a
- FIG. 4b an alternative form of a contact region 11 is shown, which has only at defined contact points 12 a spherical geometry or a radius. Both types of the shape of the contact region 11 are suitable for producing an intermodulation-free contact between high-frequency component 2 and contact element 1.
- the contact region 21 of the high-frequency component 2 is not formed as a recess in the high-frequency component 2, but as contact legs on the high-frequency component 2.
- FIG. 5 shows a sectional view of an arrangement according to another embodiment of the present invention.
- a so-called cascading is shown.
- the contact element 1 therefore has contact areas 11 and 111 at both distal ends.
- these contact regions 11 and 111 are shaped in such a way that they have a radius or a spherical geometry at least at predetermined contact points 12 and 112. It is not necessary that both contact areas 11 and 111 have the same shape, which may have advantages in terms of production technology.
- the advantage of the spherical geometry present at least at the contact points 12 and 112 is very clear here. If position inaccuracies are present, the inaccuracy can be compensated for by turning or tilting one of the contact elements 1 without the defined contact between high-frequency component 2 and contact element 1 being lost.
- the region of the high-frequency component 2 for receiving the contact region 11 of the contact element 1 can be both a recess in the high-frequency component 2 and as contact legs on the high-frequency component 2 as before may be formed described.
- the contact portion 11 of the contact element 1 may be formed as a complete ball or only at predetermined contact points 12 have a spherical geometry or a radius. This means that any combination of region 21 of the high-frequency component 2 for receiving the contact region 11 of the contact element 1 and the shape of the contact region 11 of the contact element 1 leads to the result of producing a reproducible, permanent intermodulation-free electrical contact.
- FIGS. 6 and 7 each show a sectional view of an arrangement according to different embodiments of the invention, wherein as an example a dipole 10 is arranged on a reflector sheet 2 as a high-frequency component to be contacted.
- a dipole 10 is arranged on a reflector sheet 2 as a high-frequency component to be contacted.
- the area 21 of the high-frequency component here the reflector sheet 2, as a well, in FIG. 7 as an inverted pan or bulge formed and has at the contact points 12 rounded edges.
- the contact region 11 of the contact element 1 in both figures only at the contact points 12 has a spherical geometry. This is sufficient for intermodulation-free contact since electrical currents flow only over the contact points or surfaces.
- the spherical geometry or the radius so that position inaccuracies can be compensated. Since production of spherical shapes is complicated and expensive, production costs can be saved by means of a ball-geometric shape required only at the contact points 12 or by a radius. Also, the residual shape of the contact region 11 can basically be chosen as desired as long as the contacting at the contact points 12 is ensured by the current flow properties.
- FIG. 6 shows an example of a possible shape of the contact area 11 within the recess 21 in the reflector sheet 2. As in FIG. 3 Here is the contact area 11 formed of the contact element 1 to the bottom of the recess 21, resulting in the same advantages as described above.
- FIG. 7 shows an alternative embodiment of the region 21 of the high-frequency component, here the reflector plate 2, for receiving the dipole 10.
- the region 21 is formed here as a bulge, on which the dipole 10 is placed for contacting. Again, only the rounded edges of the dipole 10 and the portion 21 of the reflector plate 2 for electrical contact, ie the electrical contact takes place here only at the contact points 12, as stated for the embodiments shown above. For stable attachment of the dipole 10, this may rest on the bulge between the contact points 12 and be additionally fastened to the reflector plate 2 with a further fastening means.
- a screw 100 is inserted through the underside of the reflector plate 2 into the contact region 11 of the contact element 1 for fastening the contact element 1.
- the screw serves only to reinforce the attachment of the contact element 1 and can also be replaced by other fasteners or not be present at all.

Description
Die Erfindung betrifft eine Anordnung zur intermodulationsfreien elektrischen Kontaktierung von elektrisch leitfähigen Elementen gemäß dem Oberbegriff des Patentanspruchs 1, sowie ein erstes elektrisch leitfähiges Element gemäß dem Oberbegriff des Patentanspruchs 13 und ein zweites elektrisch leitfähiges Element gemäß dem Oberbegriff des Patentanspruchs 15.The invention relates to an arrangement for intermodulation-free electrical contacting of electrically conductive elements according to the preamble of
In der Antennentechnik werden hohe Anforderungen an die Kontaktierung zwischen Hochfrequenzelementen gestellt. Ein Hauptproblem bei der Kontaktierung stellen nicht definierte Kontakte zwischen Hochfrequenzleitern aufgrund ungünstiger Formgebung der Kontaktstellen dar. Diese nicht definierten Kontakte führen in der Hochfrequenztechnik zu unerwünschten passiven Intermodulationsprodukten, kurz PIM, resultierend aus der sogenannten Intermodulation. Intermodulation ist die parasitäre Mischung zweier unterschiedlicher Trägerfrequenzen, die zu sogenannten Oberwellen führen, eben jenen passiven Intermodulationsprodukten, die zu Störungen führen können. Eine ungünstige Kontaktstelle resultiert z.B. aus erhöhtem Verschleiß an den Kontaktstellen. Toleranzen wie Rauigkeit und (Un-)Ebenheit, sowie mehrfach Passungen, wodurch undefinierte Kontakte entstehen, sind ein Hauptgrund für unerwünschte Intermodulation.In antenna technology, high demands are placed on the contact between high-frequency elements. A main problem in the contacting represent undefined contacts between high-frequency conductors due to unfavorable shaping of the contact points. These undefined contacts result in the high-frequency technology to unwanted passive intermodulation products, short PIM, resulting from the so-called intermodulation. Intermodulation is the parasitic mixture of two different carrier frequencies, which lead to so-called harmonics, just those passive intermodulation products that can lead to interference. An unfavorable contact point results e.g. from increased wear at the contact points. Tolerances such as roughness and (un) flatness, as well as multiple fits resulting in undefined contacts, are a major cause of unwanted intermodulation.
Galvanische Kontakte zwischen Hochfrequenzkomponenten sind beispielsweise Kontakte zwischen Dipol und Reflektor bzw. anderen Komponenten und Reflektor, einem Deckel auf einem Gehäuse oder aber auch die Kontakte von Hochfrequenzschaltern.Galvanic contacts between high-frequency components are, for example, contacts between dipole and reflector or other components and reflector, a cover on a housing or even the contacts of high-frequency switches.
Feste galvanische Kontakte werden üblicherweise hergestellt, indem leitende Flächen von zwei Leitern miteinander verpresst bzw. verschraubt werden. Aufgrund der Tatsache, dass der Kontakt dauerhaft und fest sein muss, ist eine hohe Krafteinwirkung nötig, um dies zu erreichen. Dies erfordert einen hohen Produktionsaufwand. Zusätzlich ist problematisch, dass bei nicht vollkommen ebenen Flächen oder einem leicht schiefen Aufbringen einer der Flächen kleinere Spalte bzw. Ausnehmungen zwischen den Leitern entstehen können, durch welche die elektrischen Ströme und damit die Eigenschaften des Kontakts undefiniert werden und unerwünschte Intermodulationen entstehen können. Diese Toleranzen können teilweise durch extrem hohe Kraft beim Verpressen ausgeglichen werden, was aber wiederum einen hohen Produktionsaufwand und hohe Energie erfordert, sowie einen erhöhten konstruktiven Aufwand an die Geometrie stellt.Fixed galvanic contacts are typically made by crimping conductive surfaces of two conductors together. Due to the fact that the contact must be permanent and strong, a high force is needed to achieve this. This requires a high production cost. In addition, it is problematic that when not perfectly flat surfaces or a slightly oblique application of one of the surfaces smaller gaps or recesses may arise between the conductors, through which the electrical currents and thus the Contact characteristics become undefined and unwanted intermodulation can occur. These tolerances can be partially compensated by extremely high force during pressing, which in turn requires a high production cost and high energy, as well as an increased design effort on the geometry.
Für bewegliche Kontakte wie Hochfrequenzschalter werden beispielsweise galvanische Kontakte hergestellt, indem ein festes Element mittels zweier beweglicher Leiter kontaktiert wird. Die Form des festen Elements bestimmt hierbei die Gegenform der anderen Leiter. Klassische Kontakte werden über ebene Flächen hergestellt, wie in der
Bei den bekannten Schaltern spielen weder eine intermodulationsfreie Verbindung noch größere Toleranzen oder Unebenheiten eine Rolle, es wird lediglich auf eine ausreichende Kontaktierung der Leiter geachtet.Neither an intermodulation-free connection nor larger tolerances or unevenness play a role in the known switches, care is taken only to make sufficient contact with the conductors.
Aus den oben genannten Gründen ist es eine Aufgabe dieser Erfindung, eine Anordnung bereitzustellen, bei der ein reproduzierbarer, dauerhaft guter intermodulationsfreier elektrischer Kontakt zwischen Hochfrequenz-Komponenten und zugehörigen Kontaktelementen möglich ist. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.For the above-mentioned reasons, it is an object of this invention to provide an arrangement in which a reproducible, permanently good intermodulation-free electrical contact between high-frequency components and associated contact elements is possible. This object is achieved by the features of

In einer weiteren Ausführung sind das erste und das zweite elektrisch leitfähige Element als Hochfrequenz-Komponenten ausgebildet, die es miteinander zu kontaktieren gilt. Solche Komponenten sind üblicherweise mittels leitfähiger Schirmgehäuse ausgeführt. In einer weiteren Ausführung ist das erste elektrisch leitfähige Element als eine Hochfrequenz-Komponente und das zweite elektrisch leitfähige Element als ein Kontaktelement ausgebildet das einen elektrischen Leiter umfasst, an dessen distalem Endbereich der Kontaktbereich angeordnet ist. In einer weiteren vorteilhaften Ausführung ist das erste und/oder das zweite elektrisch leitfähige Element als ein Reflektorblech, ein Gehäuse, ein Filtergehäuse, ein Bias-T, ein Wärmeableiter, ein Schalter oder Schalterkontakte, ein Dipol oder Hochfrequenzleiter ausgebildet.In a further embodiment, the first and the second electrically conductive element are designed as high-frequency components, which is to be contacted with each other. Such components are usually carried out by means of conductive shielding housing. In a further embodiment, the first electrically conductive element is designed as a high-frequency component and the second electrically conductive element as a contact element which comprises an electrical conductor, at the distal end region of which the contact region is arranged. In a further advantageous embodiment, the first and / or the second electrically conductive element as a reflector sheet, a housing, a filter housing, a bias T, a heat sink, a switch or switch contacts, a dipole or high-frequency conductor is formed.
Durch die punktartige Kontaktierung der Hochfrequenzkomponente mit dem Kontaktelement kann eine gleichmäßige und dauerhafte Kontaktierung sowie ein Toleranzausgleich bei nicht exakter Montage erzielt werden. Außerdem werden deutlich geringere Kräfte für die Verbindung der Komponenten benötigt ohne dass dabei die Qualität des Kontaktes leidet. Vorteilhaft ist des Weiteren, dass jegliche elektrisch leitfähigen Elemente miteinander elektrisch kontaktiert werden können, z.B. Hochfrequenzkomponenten mit Hochfrequenzkomponenten, Hochfrequenzkomponenten mit elektrischen Leitern, elektrische Leiter mit anderen elektrischen Leitern.By the point-like contacting of the high-frequency component with the contact element, a uniform and permanent contact and tolerance compensation can be achieved with inaccurate installation. In addition, significantly lower forces are required for the connection of the components without the quality of the contact suffers. It is also advantageous that any electrically conductive elements can be electrically contacted with each other, for example, high-frequency components with high-frequency components, high-frequency components with electrical conductors, electrical conductors with other electrical conductors.
Des Weiteren ist erfindungsgemäß vorgesehen, dass der Bereich des ersten elektrisch leitfähigen Elements zur Aufnahme des zweiten elektrisch leitfähigen Elements eine Ausnehmung in dem ersten elektrisch leitfähigen Element ist. Hierdurch wird eine Serienproduktion der Hochfrequenz-Komponente mit integrierter Ausnehmung ermöglicht, was wiederum zu einer günstigeren Produktion führt.Furthermore, it is provided according to the invention that the region of the first electrically conductive element for receiving the second electrically conductive element is a recess in the first electrically conductive element. As a result, a series production of the high-frequency component with integrated recess is made possible, which in turn leads to a more favorable production.
Alternativ umfasst der Bereich des ersten elektrisch leitfähigen Elements zur Aufnahme des zweiten elektrisch leitfähigen Elements zumindest zwei Kontaktbeine, die an dem ersten elektrisch leitfähigen Element angeordnet sind. Somit können auch sehr dünne Materialien oder Materialien, bei denen das Bilden einer integrierten Aufnahme schwierig oder teuer ist, verwendet werden.Alternatively, the region of the first electrically conductive element for receiving the second electrically conductive element comprises at least two contact legs, which are arranged on the first electrically conductive element. Thus, even very thin materials or materials where forming an integrated receptacle is difficult or expensive can be used.
In einer weiteren vorteilhaften Ausbildung umfasst der Bereich zur Aufnahme des zweiten elektrisch leitfähigen Elements drei Kontaktbeine, die an dem ersten elektrisch leitfähigen Element angeordnet sind. Dies hat den Vorteil, dass somit eine Dreipunktauflage entsteht, die sehr stabil ist, aber durch die punktförmige Kontaktierung trotzdem eine große Toleranz bei der Montage zulässt.In a further advantageous embodiment, the region for receiving the second electrically conductive element comprises three contact legs, which are arranged on the first electrically conductive element. This has the advantage that thus creates a three-point support, which is very stable, but still allows a large tolerance in the assembly by the punctiform contact.
Des Weiteren ist erfindungsgemäß vorgesehen, dass der Bereich des ersten elektrisch leitfähigen Elements zur Aufnahme des zweiten elektrisch leitfähigen Elements eine Auswölbung in dem ersten elektrisch leitfähigen Element ist. Hierdurch wird eine Serienproduktion des ersten elektrisch leitfähigen Elements mit integrierter Ausnehmung ermöglicht, was wiederum zu einer günstigeren Produktion führt. Zusätzlich dient der Bereich zwischen den Kontaktpunkten als Auflage für das erste elektrisch leitfähige Element und trägt somit zur Stabilisierung des Systems bzw. der Anordnung bei.Furthermore, it is provided according to the invention that the region of the first electrically conductive element for receiving the second electrically conductive element is a bulge in the first electrically conductive element. As a result, a series production of the first electrically conductive element with integrated recess is made possible, which in turn leads to a more favorable production. In addition, the area between the contact points serves as a support for the first electrically conductive element and thus contributes to the stabilization of the system or the arrangement.
Des Weiteren ist erfindungsgemäß vorgesehen, dass das zweite elektrisch leitfähige Element und/oder der Bereich des ersten elektrisch leitfähigen Elements zur Aufnahme des zweiten elektrisch leitfähigen Elements an vorgegebenen Kontaktbereichen abgeschrägte Kanten aufweist. Alternativ weist der Bereich des ersten elektrisch leitfähigen Elements zur Aufnahme des zweiten elektrisch leitfähigen Elements zumindest an vorgegebenen Kontaktbereichen einen Radius auf. Durch das Bereitstellen von abgeschrägten Kanten oder einem Radius wird eine größere Toleranz bei der Montage erlaubt, da die Komponente auch mit einer Schräglage oder leicht gekippt montiert werden kann ohne dabei das erste elektrisch leitfähige Element an einer weiteren Stelle zu berühren und somit einen unerwünschten elektrischen Kontakt zu erzeugen. Dabei ist der Bereich unterhalb der Kontaktpunkte, also zwischen den Kontaktpunkten und der Oberfläche der des zweiten elektrisch leitfähigen Elements nicht kritisch, d.h. hier kann eine Berührung zwischen erstem und zweitem elektrisch leitfähigen Element erfolgen, da die Ströme nur über die Oberfläche fließen, d.h. über die Kontaktpunkte zum Leiter. In diesem Bereich ist es wichtig, dass keine weitere oder ungleichmäßige Kontaktierung erfolgt.Furthermore, it is provided according to the invention that the second electrically conductive element and / or the region of the first electrically conductive element for receiving the second electrically conductive element has beveled edges at predetermined contact regions. Alternatively, the region of the first electrically conductive element for receiving the second electrically conductive element has a radius at least at predetermined contact regions. Providing beveled edges or a radius becomes a larger tolerance allowed during assembly, since the component can be mounted with a tilt or slightly tilted without touching the first electrically conductive element at a further location and thus to produce an undesirable electrical contact. In this case, the area below the contact points, ie between the contact points and the surface of the second electrically conductive element is not critical, ie, a contact between the first and second electrically conductive element can take place, since the currents flow only over the surface, ie over the Contact points to the leader. In this area it is important that no further or uneven contacting takes place.

In den nachfolgenden Figurenbeschreibungen sind gleiche Elemente bzw. Funktionen mit gleichen Bezugszeichen versehen.
Intermodulationen treten beispielsweise bei nahe aneinander liegenden Sendefrequenzen mit hoher Leistung, z.B. bei Sendeanlagen in der Nachrichtentechnik, auf und erzeugen unerwünschte Störfrequenzen. Solche störenden Frequenzen treten nicht nur in großen Sendesystemen auf, sondern auch im Inneren der Antenne aufgrund beispielsweise schlechter Metall zu Metall Verbindungsstellen oder ungleichmäßiger Kontaktflächen. Ungleichmäßige Kontaktflächen sind sehr schwer zu vermeiden, da bei der Verpressung von zwei Flächen sehr hohe Kräfte aufgewendet werden müssen, um eine feste Verbindung zu schaffen. Wenn die beiden aufeinander gepressten Flächen nicht absolut eben sind, ist es sehr wahrscheinlich, dass der Kontakt zwischen den Flächen nicht auf der gesamten Fläche gleichmäßig ist. Somit können unerwünschte Intermodulationen entstehen. Dieses Problem wird durch die erfindungsgemäße Anordnung gelöst.In the following description of the figures, the same elements or functions are provided with the same reference numerals.
Intermodulation occur, for example, at close to each other transmission frequencies with high power, eg in transmitters in telecommunications, and produce unwanted spurious frequencies. Such disturbing frequencies occur not only in large broadcasting systems, but also inside the antenna due to, for example, poor metal to metal joints or uneven contact surfaces. Uneven contact surfaces are very difficult to avoid, since when pressing two surfaces very high forces must be used to create a solid connection. If the two pressed surfaces are not absolutely flat, it is very likely that the contact between the surfaces is not uniform over the entire surface. Thus, unwanted intermodulation can arise. This problem is solved by the arrangement according to the invention.
Unter Hochfrequenzelement sind Hochfrequenz-Komponenten wie Reflektorbleche, ein Gehäuse oder andere Komponenten wie Filtergehäuse, Bias-T, Wärmeableiter, Schalter oder Schalterkontakte, Dipol, Hochfrequenzleiter jeder Art etc zu verstehen. Dabei sind als leitende Bereiche Innenleiter, Außenleiter oder jede Art von leitenden Bereichen eines zu kontaktierenden Elements möglich, je nachdem welche Komponenten kontaktiert werden. Beispiele für unterschiedliche Kontaktierungen sind in
Durch die kugelgeometrische Form bzw. einen Radius an den Kontaktbereichen 11 wird sichergestellt, dass die Kontaktbereiche 11 zwischen der Hochfrequenz-Komponente 2 und dem Kontaktelement 1 eine definierte punktförmige Kontaktfläche bilden. Auch wird durch die kugelgeometrische Form dieselbe Kontaktgeometrie auch bei Toleranzen und Lageungenauigkeiten ermöglicht, so das ein dauerhaft guter intermodulationsfreier elektrischer Kontakt und eine sehr gute Reproduzierbarkeit sichergestellt werden kann, ohne entsprechend hohe Kontaktkräfte aufbringen zu müssen. In dieser Ausführung ist der Kontaktbereich 11 als vollständige Kugel gezeigt. Allerdings ist es ausreichend, an vorgegebenen Kontaktpunkten 12 zwischen Hochfrequenz-Komponente 2 und Kontaktbereich 11 eine kugelförmige Geometrie bzw. einen Radius am Kontaktbereich 11 bereitzustellen, um einen reproduzierbaren, dauerhaften intermodulationsfreien elektrischen Kontakt zwischen Hochfrequenz-Komponente 2 und Kontaktelement 1 herzustellen.The spherical geometry or a radius at the

In dieser Ausführungsform gilt wie für alle vorher beschriebenen Ausführungsformen, dass der Bereich der Hochfrequenz-Komponente 2 zur Aufnahme des Kontaktbereichs 11 des Kontaktelements 1 sowohl eine Ausnehmung in der Hochfrequenz-Komponente 2 sein kann als auch als Kontaktbeine auf der Hochfrequenz-Komponente 2 wie vorher beschrieben ausgebildet sein kann. Auch der Kontaktbereich 11 des Kontaktelements 1 kann als komplette Kugel ausgebildet sein oder nur an vorgegebenen Kontaktpunkten 12 eine kugelförmige Geometrie bzw. einen Radius aufweisen. Das heißt, dass jede beliebige Kombination aus Bereich 21 der Hochfrequenz-Komponente 2 zur Aufnahme des Kontaktbereichs 11 des Kontaktelements 1 und Form des Kontaktbereichs 11 des Kontaktelements 1 zu dem Ergebnis führt, einen reproduzierbaren, dauerhaften intermodulationsfreien elektrischen Kontakt herzustellen.In this embodiment, as for all previously described embodiments, the region of the high-
