Technologischer HintergrundTechnological background

Ein Angriffsvektor zur Datenspionage setzt an den Stromleitungen von IT-Komponenten an. An öffentliche (Haus-)Stromversorgungsnetze angeschlossene Monitore, Computer, Festplattenstationen, biometrische und andere Zugangsvorrichtungen, Kryptographievorrichtungen und dergleichen elektrische und elektronische Geräte (nachfolgend IT-Komponenten genannt) speisen im Betrieb unvermeidbar Signale in das Stromnetz zurück, die von einem Angreifer direkt am Stromversorgungsnetz oder indirekt über weitere Kopplungen, beispielsweise an metallischen Rohrleitungssystemen, abgegriffen und ausgewertet werden können zwecks Rückschluss auf digitale Informationen wie etwa auf die an einem Computer angezeigten Daten.An attack vector for data espionage connects to the power lines of IT components. Monitors, computers, hard disk drives, biometric and other access devices, cryptographic devices and the like (called IT components hereinafter) are unavoidably fed into the power network by an attacker directly on the power supply network or indirectly via further couplings, for example on metallic piping systems, can be tapped and evaluated for purposes of inference to digital information such as the data displayed on a computer.

Zur Vermeidung der Einkopplung derartiger Signale in ein Stromnetz bei sicherheitsrelevanten Tätigkeiten, z.B. im militärischen Bereich oder bei Banken, finden im Stand der Technik z.B. nach DE 20 2011 005 191 U1 Steckkontaktelemente Verwendung.In order to avoid the coupling of such signals in a power network in safety-related activities, eg in the military field or banks, find in the prior art, for example DE 20 2011 005 191 U1 Plug contact elements use.

Nachteilig ist dabei der Aufwändige Aufbau zum Erreichen der teils normenbedingt zu erreichenden Abschirmwerte.The disadvantage here is the time-consuming construction to achieve the partly normed condition to be achieved by shielding.

Zusammenfassung der ErfindungSummary of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, ein Steckkontaktelement zur abhörsicheren Versorgung einer IT-Komponente mit elektrischer Energie nach dem Oberbegriff des Anspruchs 1 sowie eine Baueinheit und eine Endkappe dafür nach dem Oberbegriff des Anspruchs 9 bzw. 10 zu schaffen, die bei vereinfachtem Aufbau eine verbesserten Schutz gegen stromversorgungsseitiges Abhören ermöglichen.The invention is therefore based on the object, a plug-in contact element for the tap-proof supply of an IT component with electrical energy after the The preamble of claim 1 and a structural unit and an end cap therefor according to the preamble of claim 9 or 10 to provide that allow a simplified design improved protection against power supply side listening.

Diese Aufgabe wird entsprechend den Merkmalen des Anspruchs 1, 9 bzw. 10 gelöst.This object is achieved according to the features of claim 1, 9 and 10, respectively.

Demnach wird ein Steckkontaktelement zur abhörsicheren Versorgung einer IT-Komponente mit elektrischer Energie geschaffen, umfassend ein Gehäuse mit einem Steckkontakt zum elektrischen Anschluss der IT-Komponente, einen sich aus dem Gehäuse heraus erstreckenden elektrischen Verbinder zum Anschluss an eine Energiequelle wie etwa eine Hausstromsteckdose sowie ein im Gehäuse angeordnetes Filterelement, wobei das Gehäuse energiequellenanschlussseitig eine separat ausgebildete, elektrisch leitende Endkappe mit einem Tubus aufweist, der das Filterelement 4-seitig kontaktiert abgeschirmt trägt und mit dem Gehäusekörper über eine EMV-Dichtung verbunden ist. Die Verwendung eines von der Endkappe getragenen, allseitig abgeschirmten Filterelements ermöglicht einen modularen und damit vereinfachten Aufbau bei hoher Abschirmleistung.Accordingly, a plug-in contact element is provided for the tap-proof supply of an IT component with electrical energy comprising a housing with a plug contact for electrical connection of the IT component, an extending out of the housing electrical connector for connection to a power source such as a domestic power outlet and a arranged in the housing filter element, wherein the housing energy source terminal side has a separately formed, electrically conductive end cap with a tube that shields the filter element contacted on four sides wearing and is connected to the housing body via an EMC seal. The use of a supported by the end cap, all-round shielded filter element allows a modular and thus simplified design with high shielding performance.

Die energiequellenanschlussseitige Endkappe, das Filterelement und die EMV-Dichtung(en) können dabei eine in den Gehäusegrundkörper einschiebbare Baueinheit bilden, die einen modularen und vereinfachten Aufbau sowie eine einfache Montage ermöglicht.The energy source connection-side end cap, the filter element and the EMC seal (s) can thereby form an insertable into the housing body assembly that allows a modular and simplified design and easy installation.

Zweckmäßigerweise sind zwei EMV-Dichtungen beiderseits eines (Verdrahtungs-)Zwischenraums vorgesehen, wodurch die Abschirmung optimiert wird, insbesondere bei Verwendung eines separaten Bodenerders und elektrischer Verbindung der Abschirmung des elektrischen Verbinders mit der Endkappe.Conveniently, two EMC gaskets are provided on either side of a (wiring) space, thereby optimizing the shield, particularly when using a separate ground earth and electrical connection of the shield of the electrical connector to the end cap.

Das Filterelement kann dabei in eine Aufnahme der Endkappe eingesetzt sein. Hierdurch wird die Verwendung vorgefertigter geschirmter Filterelemente und deren gegen Signaleinkopplung abgeschirmter Verdrahtung in einem beiderseits abgeschirmten Verdrahtungszwischenraum, der durch die Aufnahme gegeben sein kann, ermöglicht.The filter element can be inserted into a receptacle of the end cap. As a result, the use of prefabricated shielded filter elements and their against signal coupling shielded wiring in a mutually shielded wiring space, which may be given by the recording allows.

Zweckmäßigerweise ist die Aufnahme dabei in Richtung auf das freie Ende verjüngt. Dies ermöglicht ein vereinfachtes Einsetzen des Filterelements, ggf. unter gleichzeitiger Zentrierung und/oder Fixierung, wofür Befestigungselemente vorgesehen sein können, die zudem einen Anschlag für eine Endlage aufweisen können.Appropriately, the recording is tapered towards the free end. This allows a simplified insertion of the filter element, possibly with simultaneous centering and / or fixing, for which fastening elements can be provided, which may also have a stop for an end position.

Am freien Ende der Aufnahme kann eine EMV-Dichtung vorgesehen sein, die den Verdrahtungszwischenraum zum Gehäuseinneren hin abschirmt und zudem eine insbesondere unterstützende mechanische Klemmung des Filterelements bilden kann.At the free end of the receptacle, an EMC seal can be provided which shields the wiring space to the housing interior and also can form a particular supporting mechanical clamping of the filter element.

An der Endkappe kann zudem ein Fußelement vorgesehen sein. Damit entfallen zusätzliche, am Gehäusekörper anzubringende Fußelemente.In addition, a foot element can be provided on the end cap. This eliminates additional, to be attached to the housing body foot elements.

Die Erfindung schafft ferner die Baueinheit sowie die Endkappe als eigenständige Erfindungsgegenstände.The invention also provides the assembly as well as the end cap as a separate subject of the invention.

Der vereinfachte Aufbau mit einem Filterelement ermöglicht damit Abkehr von im Stand der Technik im Gehäuse vorgesehenen Trennwänden zur Montage und Abschirmung von Durchführungskondensatoren. Stattdessen ermöglicht die Erfindung kraft modularen Aufbaus klar definierte, gegeneinander abgeschirmte Zonen. So bildet das Filterelement eine abgeschirmte Zone, d.h. das Innere des Filterelements ist gegen eine (insbesondere HF-)Einkopplung von außen, z.B. von den IT-Komponenten oder deren Verdrahtung, abgeschirmt. Die Verdrahtungszone zwischen Filterelement und Endkappe ist ebenfalls abgeschirmt, so dass Signale der IT-Komponenten oder des Filterelements auch in die filterelementausgangsseitige Verdrahtung nicht einkoppelbar sind.The simplified structure with a filter element thus allows departure from the prior art provided in the housing partitions for mounting and shielding of feedthrough capacitors. Instead, the invention allows clearly defined, mutually shielded zones due to modular construction. Thus, the filter element forms a shielded zone, ie the interior of the filter element is shielded against external (in particular HF) coupling from the outside, eg from the IT components or their wiring. The wiring zone between the filter element and the end cap is also shielded, so that signals of the IT components or of the filter element can not be coupled into the filter element output-side wiring.

Das in Fig. 1 dargestellte Steckkontaktelement 1 ist in Form einer Steckdosenleiste mit einem Gehäuse 2 und mehreren, hier als Schuko-Buchsen ausgeführten, darin angeordneten Steckkontakten 3 zum elektrischen Anschluss von Computern, Festplatten, Kryptographievorrichtungen, biometrischen Zugangsvorrichtrungen und/oder weiteren IT-Komponenten sowie einem sich aus dem Gehäuse heraus erstreckenden elektrischen Verbinder 4 zum Anschluss an z.B. Hausstromsteckdose ausgestaltet.This in Fig. 1 plug contact element 1 shown is in the form of a power strip with a housing 2 and several, here designed as Schuko sockets, therein plug contacts 3 for the electrical connection of computers, hard drives, cryptography devices, biometric Accessvorrichtrungen and / or other IT components and a from the Housing out extending electrical connector 4 designed for connection to eg domestic power outlet.

Das hier im in üblicher Weise langgestreckte Gehäuse 2 ist bevorzugt modular aufgebaut mit einem ggf. aus mehreren Elementen zusammengesetzten Gehäusekörper 5, hier in Form einer Profilleiste, zweckmäßigerweise einer frontseitigen Endkappe 6 sowie einer energiequellenanschlussseitigen, separat ausgebildeten und elektrisch leitenden Endkappe 7.The here in the usual way elongated housing 2 is preferably modular with a possibly composed of several elements housing body 5, here in the form of a profile strip, expediently a front end cap 6 and a power source terminal side, separately formed and electrically conductive end cap. 7

Die Endkappe 7 trägt ein hier als Baueinheit damit ausgeführtes Filterelement 8, siehe Fig. 2, welches das insbesondere "öffentliche", d.h. nicht sichere und von Dritten abhörbare Stromversorgungsnetz vom "privaten", d.h. benutzerseitigen und über die Steckkontakte 3 gebildeten Stromverteilungsnetz auf bekannte Weise dergestalt entkoppelt, dass elektrische Signale nicht vom privaten ins öffentliche Stromversorgungsnetz übertragen werden und ggf. umgekehrt.The end cap 7 carries a here as a unit designed so executed filter element 8, see Fig. 2 which decouples the particular "public", ie non-secure and audible from third party power supply network of the "private", ie user side and via the plug contacts 3 power distribution network in a known manner such that electrical signals are not transmitted from the private to the public power grid and possibly vice versa.

Die Endkappe 7 weist ferner eine Durchführung 9 für den elektrischen Verbinder 4 sowie zweckmäßigerweise einen separaten Masseanschluss 10 für eine Bodenerdung oder dergleichen auf und ist mit dem Gehäusekörper 5 über mehrere, hier beispielhaft zwei EMV-Dichtungen 11, 12 beidenends eines (Verdrahtungs-)Zwischenraum 13 verbunden, siehe Fig. 3.The end cap 7 further has a bushing 9 for the electrical connector 4 and expediently a separate ground terminal 10 for ground grounding or the like and is connected to the housing body 5 via a plurality of, in this example two EMC gaskets 11, 12 both ends of a (wiring) gap 13 connected, see Fig. 3 ,

Vorzugsweise sind die stromführenden Adern des Verbinders 4 durch die Durchführung 9 direkt in oder an das Filterelement 8 geführt (nicht dargestellt) und eine sich über die gesamte Länge des Verbinders 4 erstreckende Abschirmung ist leitend mit der Endkappe 7 und damit mit dem ggf. vorhandenen separaten Masseanschluss 10 verbunden.Preferably, the current-carrying wires of the connector 4 are routed through the bushing 9 directly into or onto the filter element 8 (not shown) and a shield extending over the entire length of the connector 4 is conductive to the end cap 7 and thus to the possibly separate one Ground connection 10 connected.

Der (Verdrahtungs-)Zwischenraum 13 zwischen Endkappe 7 und Filterelement 8, insbesondere Verdrahtungsanschluss 8a, in welchem die stromführenden Adern des Verbinders 4 zumindest abschnittsweise ohne Leitungsabschirmung verlaufen können (nicht dargestellt), wird durch die EMV-Dichtungen 11, 12 beidseitig abgeschirmt. Die EMV-Dichtungen 11, 12 können als Schnur-, Klemm- und/oder Federdichtungen ausgeführt sein. Bevorzugt erstreckt sich die EMV-Dichtung 11 um den Umfang der Endkappe 7 und ist dem stirnseitigen Ende des Gehäusekörpers 5 zugewandt dergestalt, dass im aufgesetzten Zustand die Endkappe 7 auf das stirnseitige Ende des Gehäusekörpers 5 drückend die EMV-Dichtung 11 komprimiert. Vorteilhafterweise ist die zweite EMV-Dichtung 12 am Filterelement 8 anliegend angeordnet und von einer Filterelement-Aufnahme 14 der Endkappe 7 getragen und umrundet das Filterelement 8 zweckmäßigerweise quer zur Längsachse der Filterelementlängsachse. Damit ist der (Verdrahtungs-)Zwischenraum 13 vollständig abgeschirmt. Das freie Ende 15 der Aufnahme 14 kann hierzu verjüngt oder gestuft sein, um die EMV-Dichtung 12 aufzunehmen, insbesondere in diese einzugreifen.The (wiring) gap 13 between end cap 7 and filter element 8, in particular wiring connection 8a, in which the current-carrying wires of the connector 4 can extend at least in sections without line shielding (not shown), is shielded on both sides by the EMC gaskets 11, 12. The EMC seals 11, 12 can be designed as cord, clamp and / or feather seals. Preferably, the EMC seal 11 extends around the circumference of the end cap 7 and facing the front end of the housing body 5 such that in the mounted state, the end cap 7 on the front end of the housing body 5 compressively compresses the EMC seal 11. Advantageously, the second EMC gasket 12 is disposed adjacent to the filter element 8 and supported by a filter element receptacle 14 of the end cap 7 and expediently surrounds the filter element 8 transversely to the longitudinal axis of the filter element longitudinal axis. Thus, the (wiring) gap 13 is completely shielded. The free end 15 of the receptacle 14 may be tapered or stepped to receive the EMC seal 12, in particular to intervene in this.

An der Endkappe 7 kann eine Aufnahme 16 für ein Fußelement 17, z.B. aus Kunststoff, angeformt oder befestigt sein.At the end cap 7, a receptacle 16 for a foot member 17, e.g. made of plastic, molded or fastened.

Zum elektrischen Anschluss der Steckkontakte 3 kann eine Verdrahtung in Richtung des Verdrahtungsanschlusses 8b führen.The end cap 7 with mounted filter element 8 and EMC gaskets 11, 12 preferably forms a component 18, see Fig. 4 and 5 , which is inserted into the housing base body 5 and, if necessary, via fasteners 19 with this example can be screwed. For the electrical connection of the plug contacts 3, a wiring can lead in the direction of the wiring connection 8b.

Führungs- und/oder Verbindungselemente 20, hier seitlich an der Endkappe 7 entlang der Aufnahme 14 dargestellt, können in Gegenelemente oder Aussparungen im Gehäusekörper 5 eingreifen. Zweckmäßigerweise weist die Endkappe 7 Bohrungen 21 für eine Verschraubung oder dergleichen mit dem Gehäusekörper 5 auf.Guide and / or connecting elements 20, shown here laterally on the end cap 7 along the receptacle 14, can engage in counter-elements or recesses in the housing body 5. Conveniently, the end cap 7 holes 21 for a screw or the like with the housing body 5.
