Das erfindungsgemäße, ringförmige Schirmelement ermöglicht es, die Schirmanbindung der Leiterplatte an den metallenen Buchsenmantel der Anschlußbuchse in besonders einfacher Weise vorzunehmen. Mit seinen Kontaktgliedern wird das Schirmelement auf die betreffende Leiterplatte aufgesteckt, und zwar an derjenigen Stelle, an der die durch das Zentrum der Ringebene des Schirmelementes senkrecht hindurchgehende Achse mit der Achse der zugeordneten Anschlußbuchse in der Geschlossenlage des Gehäuses zusammenfällt. So werden beim Zusammenbau des Gehäuses die darin anzuordnende Leiterplatte einerseits und die die Anschlußbuchse aufnehmende Gehäusewand relativ zueinander so zusammengebracht, daß sich der an der Innenseite der Gehäusewand vorstehende Buchsenmantel der Anschlußbuchse zwischen die Federschenkel des Schirmelementes unter deren Aufweitung selbstätig einführt.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST MODE FOR CARRYING OUT THE INVENTION

Im einzelnden zeigt Fig. 1 ein Schirmelement 1, welches mit seinen daran angeordneten Komponenten aus einem flachen Stahlblech ausgestanzt und in der nachstehend erörterten Weise partiell gebogen ist. Das Schirmelement 1 hat die Grundform eines Kreisringes, die durch den kreisförmigen Verlauf von Flachstegen 2 vorgegeben ist. Die Flachstege 2 haben eine Breite, die erheblich größer als ihre Dicke ist, welche von der Dicke des Stahlbleches bestimmt wird, aus dem das Schirmelement 2 ausgestanzt ist. Die Ringabschnitte bildenden Flachstege 2 sind in der Ringebene flachliegend angeordnet.In the single shows Fig. 1 a screen element 1, which is stamped with its components arranged thereon from a flat sheet steel and partially bent in the manner discussed below. The shield element 1 has the basic shape of a circular ring, which is predetermined by the circular course of flat webs 2. The flat webs 2 have a width which is considerably greater than their thickness, which is determined by the thickness of the steel sheet from which the screen element 2 is punched out. The ring sections forming flat webs 2 are arranged lying flat in the plane of the ring.

Die Flachstege 2 weisen jeweils an ihren beiden Enden Kröpfungen 3 auf, die von der Ringmitte weggerichtet sind und an die Abwinklungen 4 anschließen. Die Abwinklungen 4 gehen in Zwischenstege 5 über, die eben sind und die zur Ringebene des Schirmelementes 1 senkrecht stehen. Die Zwischenstege 5 haben einen gewissen Abstand von dieser Ringebene und daran schließen mittig jeweils in Richtung von der Ringebene weg Kontaktglieder 6 in Gestalt von Kontaktpins oder -pads an. Die Kontaktglieder 6 stehen somit an der einen Ringseite des Schirmelementes 1 bezogen auf die Ringebene vor und erstrecken sich in paralleler Richtung zu der senkrecht durch das Zentrum der Ringebene hindurchgehenden Achse.The flat webs 2 each have at their two ends tobends 3, which are directed away from the center of the ring and connect to the angled portions 4. The bends 4 go over into intermediate webs 5, which are flat and which are perpendicular to the ring plane of the screen element 1. The intermediate webs 5 have a certain distance from this ring plane and close to it in the middle in each case in the direction of the ring plane away contact members 6 in the form of contact pins or pads. The contact members 6 thus protrude at the one ring side of the shielding element 1 with respect to the ring plane and extend in the direction parallel to the axis passing through the center of the ring plane.

An der von den Kontaktglieder 6 abliegenden Seite schließen an die Zwischenstege 5 Federschenkel 7 an, deren Länge so bemessen ist, daß sie an der zweiten Ringseite bezogen auf die Ringebene des Schirmelementes 1 vorstehen. In der Ausgangslage sind die Federschenkel 7 leicht nach innen hin in Richtung zu der durch das Zentrum der Ringebene hindurchgehenden Achse geneigt. An den freien Enden weisen die Federschenkel nach außen abgewinkelte Endabschnitte 8 auf, wobei sich im Biegebereich an den Innenseiten der Federschenkel 7 zu den abgewinkelten Endabschnitten 8 hin Kontaktstellen 9 befinden, die für die nachstehend beschriebene elektrische Ankopplung vorgesehen sind.At the side remote from the contact members 6 side close to the intermediate webs 5 spring leg 7, whose length is dimensioned so that they protrude on the second ring side relative to the ring plane of the shield element 1. In the initial position, the spring legs 7 are inclined slightly inwards in the direction of the axis passing through the center of the ring plane. At the free ends, the spring legs have outwardly angled end portions 8, wherein in the bending region on the inner sides of the spring legs 7 to the angled end portions 8 point out contact points 9, which are for the electrical described below Coupling are provided.

Insgesamt ist das Schirmelement 1 ein drehsymmetrisches Gebilde bezogen auf die senkrecht durch das Zentrum der Ringebene hindurchgehende Achse. Vorzugsweise hat das Schirmelement 1 drei, vier oder eine noch größere Anzahl abgewinkelter Zwischenstege 5 mit den Kontaktgliedern 6 und den Federschenkeln 7.Overall, the screen element 1 is a rotationally symmetrical structure based on the axis passing through the center of the ring plane axis. Preferably, the screen element 1 has three, four or even greater number of angled intermediate webs 5 with the contact members 6 and the spring legs. 7

Wie Fig. 2 veranschaulicht, ist in der Funktionslage das Schirmelement 1 auf eine Leiterplatte 10 aufgesteckt. Das Abschirmungspotential, welches von dem Schirmelement 1 aufgenommen wird, wird von der Leiterplatte 10 in geeigneter Weise verteilt, um eine optimale Abschirmung zu erzielen. Die mechanische Befestigung und elektrische Kontaktierung des Schirmelementes 1 auf der Leiterplatte 10 erfolgt über die Kontaktglieder 6, die zu diesem Zweck als Lötpins ausgebildet sein können. Koaxial zu dem Schirmelement 1 bezogen auf die senkrecht durch die Ringebene des Schirmelementes 1 hindurchgehende Achse ist auf die Leiterplatte 10 ein Kontaktträger 12 einer Anschlußbuchse 11 fest aufgesetzt. Zu der Anschlußbuchse 11 gehört ferner ein metallener Buchsenmantel 15, der hohlzylindrisch ausgeführt ist. Der Buchsenmantel 15 ist fest in einen zylindrischen Ansatz 13 an einer Wand 14 eingesetzt, die zu einem die Leiterplatte 10 aufnehmenden Gehäuse gehört, welches in seiner Gesamtheit in der Zeichnung nicht wiedergegeben ist. Entscheidend ist, daß beim Zusammenbau bzw. Zusammenfügen des Gehäuses die Gehäusewand 14 und die Leiterplatte 10 so zueinander ausgerichtet sind und aufeinander zu bewegt werden können, daß der den Kontaktträger 12 umgebende Buchsenmantel 15 koaxial mit dem Schirmelement 1 ausgerichtet ist und bis zum Kontaktieren mit dem Schirmelement 1 verschoben werden kann.As Fig. 2 illustrated, the shield element 1 is mounted on a printed circuit board 10 in the functional position. The shielding potential received by the shielding element 1 is appropriately distributed by the printed circuit board 10 to achieve optimum shielding. The mechanical attachment and electrical contacting of the shielding element 1 on the printed circuit board 10 via the contact members 6, which may be formed for this purpose as soldering pins. Coaxially to the shielding element 1 relative to the axis passing through the plane of the ring of the shielding element 1, a contact carrier 12 of a connecting bushing 11 is fixedly mounted on the printed circuit board 10. To the connector 11 further includes a metallic jacketed jacket 15, which is designed as a hollow cylinder. The bushing jacket 15 is fixedly inserted into a cylindrical projection 13 on a wall 14, which belongs to a housing 10 receiving the housing, which is not shown in its entirety in the drawing. It is crucial that the assembly or assembly of the housing Housing wall 14 and the circuit board 10 are aligned with each other and can be moved towards each other that the contact carrier 12 surrounding bushing jacket 15 is aligned coaxially with the shield element 1 and can be moved to contact with the shield element 1.

Der Buchsenmantel 15 der Anschlußbuchse 11 steht an der Innenseite der Gehäusewand 14 vor und hat ein Innenende, welches an seiner Außenseite zu seiner freien Stirnseite hin mit einer Anfasung 16 versehen ist. Beim Fügen der Anschlußbuchse 11 fährt das Innenende des Buchsenmantels 15 zwischen die Federschenkel 7 des Schirmelementes 1 ein, die dadurch aufgeweitet werden. Dementsprechend hat das Innenende des Buchsenmantels 15 einen Außendurchmesser, der grö-ßer als der Durchmesser desjenigen Kreises ist, auf dem sich in der Ausgangslage die inneren Kontaktstellen 9 an den Federschenkeln 7 des Schirmelementes 1 befinden. Wie Fig. 3 zeigt, ist dadurch eine sichere Kontaktierung der Federschenkel 7 an dem Innenende des Buchsenmantels 15 sichergestellt.The bushing jacket 15 of the connector 11 projects on the inside of the housing wall 14 and has an inner end, which is provided on its outer side to its free end face with a chamfer 16. When joining the connector 11, the inner end of the bushing jacket 15 moves between the spring legs 7 of the shield element 1, which are thereby widened. Accordingly, the inner end of the bushing jacket 15 has an outer diameter which is greater than the diameter of that circle on which the inner contact points 9 are located on the spring legs 7 of the shielding element 1 in the starting position. As Fig. 3 shows, thereby a secure contact of the spring leg 7 is secured to the inner end of the sleeve shell 15.

Der Buchsenmantel 15 der Anschlußbuchse 11 hat ein von der Außenseite der Gehäusewand her je nach Anschlußart zugängliches Innengewinde oder Außengewinde zum Ankuppeln eines Steckers, der ein entsprechendes Gewindeteil zur Verschraubung mit dem Buchsenmantel 15 der Anschlußbuchse 11 aufweist. Dieses Gewindeteil des Steckers wiederum ist in üblicher Weise mit dem Schirm einer in einem Kabel geführten elektrischen Leitung verbunden, womit bei an die Anschlußbuchse 11 angesetztem Stecker eine elektrische Ankopplung des Leiterschirms an das Schirmelement 1 besteht.The female jacket 15 of the connector 11 has an accessible from the outside of the housing wall depending on the type of connection female thread or male thread for coupling a connector having a corresponding threaded portion for screwing to the female jacket 15 of the female connector 11. This threaded portion of the plug in turn is in the usual way with the screen of a guided in a cable connected electrical line, which is an electrical connection of the conductor shield to the screen element 1 when attached to the socket 11 plug.

Die Figuren 4 und 5 dienen zum einen der Veranschaulichung je einer Anschlußbuchse 11.1 und einer Anschlußbuchse 11.2, von denen der Buchsenmantel 15 der Anschlußbuchse 11.1 mit einem Außengewinde und der der Anschlußbuchse 11.2 mit einem Innengewinde versehen ist. Weiter machen die Figuren 4 und 5 deutlich, daß die den beiden Anschlußbuchsen 11.1 und 11.2 zugeordneten Schirmelemente 1 über Verbindungsstege 17 einander einstückig verbunden sind. So erreicht man eine verbesserte Abschirmung bei mehreren Leitungseingängen in das betreffende Gehäuse und auf die zugehörige Leiterplatte. Grundsätzlich können dann, wenn nur eine Verbindung der Schirmelemente zwischen zwei oder mehreren Anschlußbuchsen 11 erforderlich ist, die Kontaktglieder 6 am Schirmelement 1 ungenutzt bleiben oder sogar weggelassen werden. In diesem Fall werden die Schirmbleche 1 lediglich auf die Buchsenmäntel 15 der Anschlußbuchsen 11 aufgesteckt.The FIGS. 4 and 5 serve for the purpose of illustrating each of a connector 11.1 and a connector 11.2, of which the female jacket 15 of the connector 11.1 is provided with an external thread and the connector 11.2 with an internal thread. Continue to do that FIGS. 4 and 5 clearly that the two connection sockets 11.1 and 11.2 associated screen elements 1 are connected via connecting webs 17 in one piece. This achieves improved shielding at several line inputs into the relevant housing and to the associated printed circuit board. In principle, if only one connection of the shielding elements between two or more connection sockets 11 is required, the contact members 6 on the shielding element 1 can remain unused or even be omitted. In this case, the shrouds 1 are attached only to the jackets coats 15 of the sockets 11.

Fig. 6 zeigt eine Mehrzahl der Schirmelemente 1, welche über die Verbindungsstege 17 einstückig miteinander verbunden sind. In dieser Form ergibt sich eine rationelle Fertigung der Schirmelemente 1, die gegebenenfalls unter Auftrennen der Verbindungsstege 17 vereinzelt werden können. Andererseits können die zusammenhängenden Schirmelemente 1 auch im Verbund zum Einsatz kommen, sofern sie zueinander solche Abstände einnehmen, welche der Anordnung von dementsprechend nebeneinander befindlichen Anschlußbuchsen 11 entspricht. Sowohl bei Einzelverwendung als auch beim Einsatz im Verbund gleichen die Federschenkel 7 der Schirmelemente 1 aufgrund ihrer Elastizität mögliche Toleranzen an den Buchsenmänteln 15 der Anschlußbuchsen 11 oder in der Anordnung mehrerer Anschlußbuchsen 11 zueinander aus. Fig. 6 shows a plurality of the shield elements 1, which are integrally connected to one another via the connecting webs 17. In this form results in a rational production of the shielding elements 1, which can optionally be separated by separating the connecting webs 17. On the other hand, the coherent shielding elements 1 can also be used in a composite, provided they are mutually connected take such distances, which corresponds to the arrangement of accordingly juxtaposed connectors 11. Both in individual use and when used in combination the spring leg 7 of the shield elements 1 due to their elasticity possible tolerances on the female jackets 15 of the sockets 11 or in the arrangement of several sockets 11 from each other.

Die Mehr- oder Vielzahl der Schirmelemente 1 kann in Gestalt eines Rasterfeldes oder -bandes hergestellt werden. Bei dem in Fig. 6 dargestellten Beispiel haben die Schirmelemente 1 jeweils vier Flachstege 2, entsprechend sind auch die übrigen Komponenten der Schirmelemente 1 vierfach vorhanden. Die Verbindungsstege 17 schließen in radialer Richtung vorzugsweise mittig an die Flachstege 2 an, jeweils zwei benachbarte der Verbindungsstege 17 schließen demnach einen Winkel von 90° miteinander ein. Bei dem Rasterfeld gibt es somit zwei Fluchtrichtungen der Verbindungsstege 17, die ebenfalls einen Winkel von 90° miteinander einschließen. Die jeweils in einer dieser beiden Fluchtrichtungen angeordneten Verbindungsstege 17.1 und 17.2 sind gleich lang ausgeführt, ebenso können auch die in den beiden unterschiedlichen Fluchtrichtungen liegenden Verbindungsstege 17.1 und 17.2 gleich lang oder auch unterschiedlich lang sein. Dies hängt von der Konfiguration der Anschlußbuchsen 11 ab, wie sie an dem Gehäuse des jeweiligen Gerätes, insbesondere einer Sensor-Aktor-Box vorgesehen ist.The multiplicity or multiplicity of the screen elements 1 can be produced in the form of a grid field or band. At the in Fig. 6 illustrated example, the shield elements 1 each have four flat webs 2, accordingly, the other components of the shield elements 1 are four times available. The connecting webs 17 preferably connect centrally in the radial direction to the flat webs 2, in each case two adjacent connecting webs 17 thus enclose an angle of 90 ° with one another. In the grid, there are thus two escape directions of the connecting webs 17, which also form an angle of 90 ° with each other. The respectively arranged in one of these two escape directions connecting webs 17.1 and 17.2 are the same length, as well as lying in the two different escape directions connecting webs 17.1 and 17.2 be the same length or different lengths. This depends on the configuration of the sockets 11, as it is provided on the housing of the respective device, in particular a sensor-actuator box.
