Abstract

A radio-frequency contact point, especially for electromagnetic screens, having a sprung metallic contact element which is mounted by means of a holder on a first of two mutually opposite surfaces with which contact is to be made, and has a plurality of segments which extend radially outwards. The sprung contact element consists of corrosion-free metal. The segments which extend radially outwards are bent away from the first surface. A corrosion-free, metallic contact disc is fitted on the second surface, opposite the sprung contact element.

Description

Patentansprüche: 1. Hochfrequenz-Kontaktpunkt, insbesondere für elektromagnetische Abschirmungen, mit einem federnden metallischen Kontaktelement, welches mittels einer Halterung auf einer ersten von zwei einander gegenüberliegenden zu kontaktierenden Flächen befestigt ist und mehrere radial nach außen sich erstreckende Segmente aufweist, d a d u r c h g e -kennzeichnet, daß das federnde Kontaktelement aus korrosionsfreiem Metall ist, daß die radial nach außen sich erstreckenden Segmente von der ersten Fläche weggebogen sind, und daß auf der zweiten Fläche gegenüber dem federnden Kontaktelement eine korrosionsfreie metallische Kontaktscheibe angebracht ist. Claims: 1. High frequency contact point, especially for electromagnetic Shields, with a resilient metallic contact element, which by means of a bracket on a first of two opposite to be contacted Is attached to surfaces and has a plurality of radially outwardly extending segments, d a d u r c h g e - indicates that the resilient contact element is made of corrosion-free Metal is that the radially outwardly extending segments from the first Surface are bent away, and that on the second surface opposite the resilient contact element a corrosion-free metallic contact disc is attached.

2. Hochfrequenz-Kontaktpunkt nach Anspruch 1, dadurch gekennzeichnet, daß das federnde Kontaktelement und die Kontaktscheibe aufgeschweißt sind. 2. High-frequency contact point according to claim 1, characterized in that that the resilient contact element and the contact disc are welded on.

3. Hochfrequenz-Kontaktpunkt nach Anspruch 1, dadurch gekennzeichnet, daß das federnde Kontaktelement und die Kontaktscheibe mittels korrosionsfreier Schneidschrauben an den Flächen befestigt sind. 3. High-frequency contact point according to claim 1, characterized in that that the resilient contact element and the contact disc by means of corrosion-free Self-tapping screws are attached to the surfaces.

Die Erfindung betrifft einen Hochfrequenz-Kontaktpunkt nach dem Oberbegriff des Anspruchs 1, wie er aus der DE-OS 34 17 410 bekannt ist. Dort ist ein Kontaktpunkt beschrieben, der als elastische Kappe ausgebildet ist, die beweglich über eine Halterung gestülpt ist. The invention relates to a high-frequency contact point according to the preamble of claim 1, as it is known from DE-OS 34 17 410. There is a point of contact there described, which is designed as an elastic cap that is movable via a bracket is upside down.

Nachteilig daran ist, daß die zu kontaktierenden Flächen zwei blanke metallische Kontaktflächen benötigen, die langfristig sauber und korrosionsfrei bleiben müssen. Dies ist oft vom Material her nicht gewährleistet, insbesondere bei Geräten, Gehäusen, Kabinen usw., die nachträglich mit HF-Dichtungen versehen werden sollen. Der gleiche Nachteil haftet auch den bekannten linienförmigen Kontaktfedern an.The disadvantage of this is that the surfaces to be contacted are two bare surfaces need metallic contact surfaces that are clean and corrosion-free in the long term have to stay. This is often not guaranteed by the material, especially for devices, housings, cabins, etc. that are subsequently provided with HF seals should be. The same disadvantage also applies to the known linear contact springs at.

Aufgabe der Erfindung ist es, einen HF-Kontaktpunkt der eingangs genannten Art anzugeben, der für die Kontaktierung von nicht dauerhaft korrosionsfreien Flächen geeignet ist und leicht nachträglich angebracht werden kann. Die Erfindung ist im Patentanspruch 1 gekennzeichnet. Die Unteransprüche beinhalten vorteilhafte Ausführungen der Erfindung. The object of the invention is to provide an HF contact point of the initially Specify the type specified for the contacting of non-permanently corrosion-free Surface is suitable and can easily be attached afterwards. The invention is characterized in claim 1. The subclaims contain advantageous ones Embodiments of the invention.

Die Erfindung wird im folgenden anhand der Figuren näher erläutert F i g. 1 zeigt ein bevorzugtes Ausführungsbeispiel der Erfindung. Zwei einander gegenüberliegende Flächen 1 und 2 sind gegeneinander beweglich und HF-mäßig zu kontaktieren. Das federnde metallische Kontaktelement 3 besteht aus korrosionsfreiem Metall und weist mehrere radial nach außen sich erstreckende Segmente auf, welche von der ersten Fläche 1, auf welcher das Element 3 befestigt ist, weggebogen sind. Auf der zweiten Fläche 2 ist eine korrosionsfreie metallische Kontaktscheibe 4 angebracht. Kontaktelement 3 und Kontaktscheibe 4 sind jeweils mit korrosionsfreien Blechschrauben 5 mit Schneidgewinde an die Flächen 1 bzw. 2 angeschraubt Zusätzlich sind noch korrosionsfreie Unterlegscheiben 6 und 7 mit außenliegenden Schneidfederringen untergelegt. The invention is explained in more detail below with reference to the figures F i g. 1 shows a preferred embodiment of the invention. Two each other Opposite surfaces 1 and 2 can be moved against each other and are to be contacted in terms of HF. The resilient metallic contact element 3 consists of corrosion-free metal and has a plurality of radially outwardly extending segments, which from the first Surface 1 on which the element 3 is attached are bent away. On the second A corrosion-free metallic contact disk 4 is attached to surface 2. Contact element 3 and contact washer 4 are each fitted with corrosion-free self-tapping screws 5 with cutting threads screwed to surfaces 1 and 2. In addition, there are corrosion-free washers 6 and 7 underlaid with external cutting spring washers.

Zum Anbringen des erfindungsgemäßen Kontaktpunktes müssen lediglich zwei Löcher gebohrt werden. To attach the contact point according to the invention only need two holes to be drilled.

So ist eine gut leitende Kontaktierung gewährleistet, auch ohne daß die Flächen 1 und 2 behandelt (blankgeschliffen) werden müßten. Es können weitgehend handelsübliche Materialien verwendet werden.In this way, a good conductive contact is guaranteed, even without surfaces 1 and 2 would have to be treated (polished). It can largely Commercially available materials are used.

Alternativ können Kontaktelement 3 und Kontaktscheibe 4 auch angeschweißt werden. Alternatively, contact element 3 and contact washer 4 can also be welded on will.

Fig. 2 zeigt noch einmal das Kontaktelement 3 in Draufsicht und eines seiner Segmente im Querschnitt. Fig. 2 shows again the contact element 3 in plan view and one its segments in cross section.

Die Segmente weisen an ihren Enden vorzugsweise gerundete Punktkontakte 8 auf.The segments preferably have rounded point contacts at their ends 8 on.

Durch Kaskadierung des erfindungsgemäßen HF-Kontaktpunktes ist eine linienförmige Abschirmung, z. B. von Türen, Luken usw., mit ausreichender Dämpfung erreichbar. Sie ist sehr einfach nachrüstbar. Bei 5 cm Abstand der Kontaktpunkte bei einer ansonsten HF-dichten Tür und Türzarge erreicht man z. B. folgende Dämpfungen: dB bei 10kHz; dB bei 1 MHz. By cascading the RF contact point according to the invention, a linear shielding, e.g. B. doors, hatches, etc., with sufficient damping accessible. It is very easy to retrofit. At a distance of 5 cm between the contact points with an otherwise HF-tight door and door frame, z. B. the following attenuation: dB at 10kHz; dB at 1 MHz.
