Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur elektrischen Verbindung von Schirmungskappen mehrpoliger Stecker mit der Erdpotentialschicht einer mehrere, senkrecht auf ihr stehende Kontaktelemente enthaltenden Verdrahtungsplatte.The invention relates to a device for the electrical connection of shielding caps of multi-pole plugs to the ground potential layer of a wiring board containing a plurality of contact elements perpendicular to it.
Durch die DE-PB-27 40 684 ist bekannt, daß die Schirmungskappe eines Schaltkabels auf der Trägerplatine einer Baugruppe befestigt und beim Einschieben des Kabelsteckers über die Kontaktelemente mit der Erdpotentialschicht eines Baugruppenrahmens elektrisch verbunden wird. Die Kontaktelemente sind am Baugruppenrahmen als Kontaktfedern ausgebildet. Die Schirmungskappen sind mit geeigneten Kontaktflächen versehen, auf die die Kontaktfedern im gesteckten Zustand des Steckers drücken und somit die Schirmungskappen mit dem Erdpotential elektrisch verbinden. Diese bekannte Vorrichtung weist nicht die kürzeste und damit niederohmigste Verbindung zwischen Schirmungskappe und Erdpotentialschicht der Verdrahtungsplatte auf. Erhöhte Signalverarbeitungsgeschwindigkeiten und damit höhere Störfelder der Signalleitungen sowie die wachsende Zahl von Steckerpolen erfordern eine wirksamere Abschirmung der Stecker und Steckerleisten.From DE-PB-27 40 684 it is known that the shielding cap of a switching cable is fastened to the carrier board of an assembly and is electrically connected to the earth potential layer of an assembly frame when the cable connector is inserted via the contact elements. The contact elements are designed on the assembly frame as contact springs. The shielding caps are provided with suitable contact surfaces, which are pressed by the contact springs when the plug is inserted and thus electrically connect the shielding caps to the earth potential. This known device does not have the shortest and therefore the lowest resistance connection between the shielding cap and the earth potential layer of the wiring board. Increased signal processing speeds and thus higher interference fields in the signal lines as well as the increasing number of connector poles require more effective shielding of the connectors and connector strips.
Der Erfindung liegt die Aufgabe zugrunde, die Verbindung zwischen Schirmungskappen mehrpoliger Stecker zur Erdpotentialschicht der Verdrahtungsplatte kurz und damit niederohmig zu halten, sowie die zusätzlichen Anforderungen zu erfüllen.The invention has for its object the connection between shield caps multi-pin connector to the earth potential layer to keep the wiring board short and thus low-resistance, and to meet the additional requirements.
Die Lösung dieser Aufgabe wird ausgehend von der eingangs beschriebenen Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 definiert. Hierbei sind die Kontaktelemente direkt auf der Verdrahtungsplatte und die Federelemente direkt an den Schirmungskappen angebracht um damit eine sehr kurze Verbindung zwischen Schirmungskappen mehrpoliger Stecker und der Verdrahtungsplatte zu erlangen. Außerdem können die Schirmungskappen bis zur Verdrahtungsplatte reichen und somit die Schirmung von Steckverbindungen verbessern.The solution to this problem is defined on the basis of the device described at the outset by the characterizing features of
Anstelle der üblichen Konaktmesser als Kontaktelemente der Verdrahtungsplatte können bei geeignetem Baugruppenabstand Versteifungsbleche, wie in EP-A-0175942 (veröffentlicht 2.4.86, die als Stand der Technik gemäß Art. 54(3) EPÜ angesehen ist) beschrieben, vorgesehen werden.Instead of the usual contact knives as contact elements of the wiring board, stiffening plates, as described in EP-A-0175942 (published 2.4.86, which is considered to be state of the art according to Art. 54 (3) EPC) can be provided with a suitable module spacing.
Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen. Je nachdem, ob zum Beispiel die Steckverbindungen mittels Kabel- oder Baugruppenstecker und ohne bzw. mit Zentrierleiste erfolgen, sind die Federelemente an den Außen- oder Innenseiten der Schirmungskappen angeordnet. Ein Anbringen von Federelementen sowohl an den Außen- als auch an den Innenseiten der Schirmungskappen ergibt zum Beispiel elektrische Verbindungen zu Kontaktmessern und Versteifungsblechen und führt somit zu noch niederohmigeren Verbindungen zur Erdpotentialschicht einer Verdrahtungsplatte.Advantageous further developments can be found in the subclaims. Depending on whether, for example, the plug connections are made using cable or assembly plugs and without or with a centering strip, the spring elements are arranged on the outside or inside of the shielding caps. Attaching spring elements to both the outside and the inside of the shielding caps results, for example, in electrical connections to contact blades and stiffening plates and thus leads to even lower-resistance connections to the earth potential layer of a wiring board.
Aus Platzgründen und/oder zur noch wirksameren Schirmung von Signalleitungen können die Kontaktmesser, die mit der Erdpotentialschicht der Verdrahtungsplatte und mit den Schirmungskappen elektrisch verbunden sind, innerhalb der Steckerbereiche angeordnet sein. Außerhalb der Steckerbereiche liegende Kontaktmesser, die mit der Erdpotentialschicht der Verdrahtungsplatte verbunden sind, können aus letztgenannten Gründen auf noch freie Steckplätze benachbarter mehrpoliger Steckverbindungen eingekröpft werden.For space reasons and / or for even more effective shielding of signal lines, the contact blades can be connected to the ground potential layer of the wiring board and are electrically connected to the shield caps, can be arranged within the connector areas. Contact knives lying outside the plug areas, which are connected to the ground potential layer of the wiring board, can be crimped onto free slots of adjacent multipole plug connections for the latter reasons.
Aus fertigungstechnischen und Kostengründen kann es sinnvoll sein, die Ränder der Schirmungskappen als Federelemente auszubilden.For manufacturing and cost reasons, it can make sense to design the edges of the shielding caps as spring elements.

Die FIG 1 bis 6 zeigen jeweils schematisierte Schnittbilder des Aufbaus geschirmter Steckverbindungen.1 to 6 each show schematic sectional views of the construction of shielded plug connections.
Das Ausführungsbeispiel nach FIG 1 zeigt eine Verdrahtungsplatte 1 mit mehreren, senkrecht auf ihr stehenden Kontaktmessern 2, 3. Auf entsprechend angeordneten Kontaktmessern 2 stecken auf der Baugruppenseite mehrpolige Baugruppenstecker 4. Zwischen den, in geeignetem Abstand sich erstreckenden Bereichen der Kontaktmesser 2 für die Baugruppenstecker sind diejenigen Kontaktmesser 3 angeordnet, die mit einer auf der Verdrahtungsplatte 1 vorhandenen Erdpotentialschicht elektrisch verbunden sind. An diesen Kontaktmessern 3 liegen beidseitig Federelemente 5, die an Schirmungskappen 6 benachbarter Baugruppenstecker 4 angebracht sind, federnd an. Diese Federelemente 5 befinden sich an den Außenseiten der Schirmungskappen 6 in der Nähe des Kappenrandes. Die etwa halbkreisförmig ausgebildeten Federelemente 5 werden gegen die Kontaktmesser 3 gedrückt, wodurch die Schirmungskappen 6 der Baugruppenstecker 4 mit der Erdpotentialschicht der Verdrahtungsplatte auf kürzestem Wege elektrisch verbunden sind. Die Schirmungskappe 6 umgibt den Baugruppenstecker 4 derart, daß diese an den in Steckrichtung weisenden Außenflächen des Baugruppensteckers 4 bündig anliegt.The exemplary embodiment according to FIG. 1 shows a
Beim Ausführungsbeispiel nach FIG 2 enthält die Verdrahtungsplatte 1 ebenfalls mehrere, senkrecht auf ihr stehende Kontaktmesser 2, 3. Auf entsprechend angeordneten Kontaktmessern 2 stecken auf der Baugruppenseite mehrpolige Baugruppenstecker 4. Zwischen den Baugruppensteckern 4 und der Verdrahtungsplatte 1 sind Zentrierleisten 7 angeordnet, die der Aufnahme der Baugruppenstecker 4 dienen. Diese Zentrierleiste 7 ist mit Durchbrüchen für die Kontaktmesser 2 versehen. Die mit der Erdschicht der Verdrahtungsplatte 1 elektrisch verbundenen Kontaktmesser 3 sind auf der Verdrahtungsplatte 1 so angeordnet, daß sie teilweise in entsprechende Aussparungen der Zentrierleiste 7 eingreifen. Diejenigen Bereiche der Kontaktmesser 3, die aus den parallel zur Steckrichtung sich erstreckenden Außenflächen der Zentrierleiste 7 heraustreten, dienen als Kontaktfläche für die elektrische Verbindung zur Schirmungskappe 8 des Baugruppensteckers 4. Die in Richtung Verdrahtungsplatte 1 weisenden Ränder der Schirmungskappen 8 dienen dabei als Federelemente 9, die etwa halbkreisförmig nach innen gewölbt so angeordnet sind, daß sie federnd an den Kontaktmessern 3 anliegen. Die Schirmungskappe 8 ummantelt den Baugruppenstecker 4 einschließlich der Zentrierleiste 7 annähernd vollständig. Um die Schirmwirkung der Steckverbindungen zu verbessern, können die Außenflächen der Schirmungskappen 8, die sich parallel zur Steckrichtung erstrecken, bis zur Verdrahtungsplatte 1 reichen.In the exemplary embodiment according to FIG. 2, the
Die FIG 3 zeigt eine Verdrahtungsplatte 1 mit mehreren, senkrecht auf ihr stehenden Kontaktmessern 2. Zwischen dem, jeweils einem Baugruppenstecker 4 zugeordneten Kontaktmesserbereich sind Versteifungsbleche 10 angeordnet, die mit der Erdpotentialschicht der Verdrahtungsplatte 1 elektrisch verbunden sind. An beiden Seiten dieser Versteifungsbleche 10 liegen etwa halbkreisförmig nach außen gewölbte Federelemente 11, die an den Kappenrändern von Schirmungskappen 12 benachbarter Baugruppenstecker 4 ausgebildet sind, federnd an und stellen somit die elektrische Verbindung zu den Schirmungskappen 12 her. Da die Versteifungsbleche 10 teilweise die Schirmung benachbarter Baugruppenstecker 4 übernehmen, ummanteln die Schirmungskappen 12 weitgehend die noch nicht geschirmten Bereiche der Baugruppenstecker 4.3 shows a
Die FIG 4 zeigt ein Ausführungsbeispiel für den Anchluß eines Kabelsteckers auf einer Verdrahtungsplatte 1 mit mehreren, senkrecht auf ihr stehenden Kontaktmessern 2, 3. Dabei befinden sich sowohl die dem jeweiligen Kabelstecker 13 zugeordneten Kontaktmesser 2 als auch die mit der Erdpotentialschicht der Verdrahtungsplatte 1 verbundenen und in Position A und E angeordneten Kontaktmesser 3 innerhalb des Kontaktmesserbereiches des jeweiligen Kabelsteckers 13. Zwischen Kabelstecker 13 und Verdrahtungsplatte 1 ist eine Zentrierleiste 14 eingefügt, die den Kabelstecker 13 annähernd formschlüssig aufnimmt. Die Zentrierleiste 14 ist mit Durchbrüchen für die Kontaktmesser 2, 3 versehen. Der Abstand der Zentrierleiste 14 und der Verdrahtungsplatte 1 ergibt sich durch die nicht dargestellten Befestigungen der Zentrierleiste 14. Den Kabelstecker 13 umgibt eine Schirmungskappe 15, an dessen Kappenrändern Federelemente 16 derart ausgebildet sind, daß sie federnd an denjenigen Kontaktmessern 3 anliegen, die mit der Erdpotentialschicht der Verdrahtungsplatte 1 elektrisch verbunden sind. Die Kabelstecker 13 weisen entsprechende Aussparungen für die Aufnahme der Federelemente 16 auf. Die etwa halbkreisförmig ausgebildeten Federelemente 16 zeigen in Richtung der benachbarten Kontaktmesser 3.4 shows an exemplary embodiment for the connection of a cable connector on a
Die FIG 5 zeigt ein weiteres Ausführungsbeispiel für den Anschluß von Kabelsteckern an einer Verdrahtungsplatte 1 mit mehreren, senkrecht auf ihr stehenden Kontaktmessern 2, 3. Zwischen den Kabelsteckern 17 und der Verdrahtungsplatte 1 sind Zentrierleisten 18 eingefügt, die die Kabelstecker 17 annähernd formschlüssig aufnehmen. Die Zentrierleisten 18 sind mit Durchbrüchen für die Kontaktmesser 2 versehen. Der Abstand der Zentrierleisten 18 und der Verdrahtungsplatte 1 ergibt sich durch die nicht dargestellten Befestigungen der Zentrierleisten 18. Die mit der Erdpotentialschicht der Verdrahtungsplatte 1 elektrisch verbundenen Kontaktmesser 3 sind auf der Verdrahtungsplatte 1 so plaziert, daß sie teilweise in entsprechende Aussparungen der Zentrierleiste 18 eingreifen. Diejenigen Bereiche der Kontaktmesser 3, die aus den parallel zur Steckrichtung sich erstreckenden Außenfläche der Zentrierleisten 18 heraustreten, dienen als Kontaktfläche für die elektrische Verbindung zur Schirmungskappe 19 des Baugruppensteckers 4. Die in Richtung Verdrahtungsplatte 1 weisenden Ränder der Schirmungskappe 19 sind als Federelemente 20 derart ausgebildet, daß sie federnd an den Kontaktmessern 3 anliegen. Die Federelemente 20 sind etwa halbkreisförmnig in Richtung Innenseite der Schirmungskappen 19 gewölbt. Diese Schirmungskappen 19 umgeben die Kabelstecker 17 einschließlich der Zentrierleisten 18 annähernd vollständig. Um die Schirmwirkung der Steckverbindung zu verbessern, können die Außenseiten der Schirmungskappen 19, die sich parallel zur Steckrichtung erstrecken, bis zum Ende der Zentrierleiste 18 oder darüber hinaus bis maximal zur Verdrahtungsplatte 1 reichen.5 shows a further embodiment for the connection of cable plugs to a
Im Ausführungsbeispiel nach FIG 6 enthält die Verdrahtungsplatte 1 wiederum mehere, senkrecht auf ihr stehende Kontaktmesser 2, 21. Die mit der Erdpotentialschicht der Verdrahtungsplatte 1 elektrisch verbundenen Kontaktmesser 21 werden auf nicht mit Kontaktmessern 2 versehenen oder frei gehaltenen Steckpositionen in Kontaktmesserreihe A oder E benachbarter Steckverbindungen eingekröpft. Die weitere Ausbildung dieses Ausführungsbeispiels entspricht der in FIG 5.In the exemplary embodiment according to FIG. 6, the
