Description
Die Erfindung betrifft einen Behälter aus faserverstärktem Kunststoff insbesondere zur Aufbewahrung und/oder zum Transport von elektronischen Geräten oder Teilen, bestehend aus einem Deckelteil und einem Bodenteil, die über Nut und Feder unter Zwischenlage einer elastischen Dichtung, dicht zusammengefügt sind, wobei mindestens die Innenflächen von Deckelteil und Bodenteil mit einer stromleitenden Schicht versehen sind. The invention relates to a container made of fiber-reinforced Plastic especially for storage and / or Transport of electronic devices or parts, consisting of from a cover part and a bottom part, which over groove and Spring with the interposition of an elastic seal, tight are joined together, at least the inner surfaces of Lid part and bottom part with an electrically conductive Layer are provided.
Derartige Behälter sollen empfindliche elektronische Geräte oder Teile gegen Beschädigungen durch Strahlung bei einer Atombombenexplosion schützen. Bei einer Atombombenexplosion werden empfindliche elektronische Bauteile durch die auftretende starke Strahlung beschädigt und damit praktisch unbrauchbar. Durch die stromleitenden Schichten von Deckelteil und Bodenteil werden solche Beschädigungen verhindert. Wichtig ist aber, daß die leitenden Schichten von Deckelteil und Bodenteil möglichst über den ganzen Umfang der Trennfuge von Deckelteil und Bodenteil leitend miteinander verbunden sind. (Zeitschrift "Elektronik" Heft 21/1984).Such containers are intended to be sensitive electronic devices or parts against damage from radiation at a Protect atomic bomb explosion. In the event of an atomic bomb explosion are sensitive electronic components by the strong radiation occurring is damaged and therefore practical unusable. Through the current-conducting layers of the cover part and bottom part such damage is prevented. Important is that the conductive layers of the cover part and Bottom part over the entire circumference of the parting line of Lid part and bottom part are conductively connected to each other. (Magazine "Electronics" issue 21/1984).
Es ist bekannt, auf der Behälterinnenseite Kontakte anzubringen, die bei geschlossenem Behälter die stromleitenden Schichten von Deckelteil und Bodenteil miteinander verbinden. Diese Kontakte auf der Behälterinnenseite sind aber hinderlich und es besteht die Gefahr der Beschädigung des Behälterinhalts, insbesondere bei auftretenden Stößen während des Transports. Außerdem besteht die Gefahr der Korrosion der Kontakte bei längerer Einlagerung.It is known on to attach contacts to the inside of the container closed container the current conducting layers of Connect the cover part and base part together. These contacts on the inside of the container are a hindrance and there is the risk of damage to the container contents, in particular if bumps occur during transport. Furthermore there is a risk of corrosion of the contacts for a long time Storage.
Es wurde auch schon versucht, die elastische Dichtung insgesamt stromleitend auszuführen. Durch auf der Behälteraußenseite vorhandene Feuchtigkeit treten hier aber Kriechströme auf, die über längere Zeit zur Beschädigung der Dichtung führen, so daß ein absoluter Schutz gegen Feuchtigkeit des Behälterinhalts nicht gewährleistet ist. Dies ist insbesondere bei der Verwendung der Behälter bei der Marine der Fall, da im Seewasserbereich in der Atmosphäre immer Salzspuren vorhanden sind.The elastic seal has also been tried to be carried out as a whole. By on the However, moisture present on the outside of the container occurs here Leakage currents that damage the Lead seal, so that an absolute protection against Moisture in the container contents is not guaranteed. This is particularly useful when using the container Navy the case because in the sea water area in the atmosphere traces of salt are always present.
Aus dem DE-GM 19 61 570 ist ein Metallgehäuse bekannt, das aus einem Deckelteil und einem Bodenteil besteht, die über Nut und Feder unter Zwischenlage einer elastischen Dichtung dicht zusammengefügt sind. Das Metallgehäuse weist ein relativ hohes Gewicht auf und ist korrosionsanfällig.From DE-GM 19 61 570 a metal housing is known which a cover part and a bottom part, which has a groove and Spring tight with the interposition of an elastic seal are put together. The metal case has a relatively high Weight on and is susceptible to corrosion.
In Vermeidung der geschilderten Nachteile liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Behälter der eingangs genannten Art so auszubilden, daß die Schutzfunktion gegen Strahlungsschäden über lange Zeit auch bei aggresiven ungünstigen Umgebungsbedingungen gewährleistet ist.In avoiding the disadvantages outlined present invention the object of a container of the type mentioned in such a way that the Protective function against radiation damage over a long time too guaranteed in aggressive, unfavorable environmental conditions is.
Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Dichtung nur auf ihrer zur Behältermitte weisenden Seite bis zu ihrer Mittelebene hin mit einer weiteren stromleitenden Schicht versehen ist und daß ferner auch die stromleitende Schicht von Deckelteil und Bodenteil nur bis zur Mittelebene der Dichtung geführt ist.To achieve this object, the invention provides that the Seal only on the side facing the middle of the container to its median level with another current-carrying one Layer is provided and that also the current-carrying Layer of cover part and base part only up to the middle level the seal is guided.
Dadurch wird das Auftreten von Kriechströmen, die Hauptursache für Undichtigkeiten sind, sicher verhindert. Gleichzeitig wird über den ganzen Außenumfang des Behälters eine ununterbrochene sichere Kontaktbrücke zwischen den stromleitenden Schichten von Deckelteil und Bodenteil gewährleistet, so daß ein optimaler Langzeitschutz erreicht wird.As a result, the occurrence of leakage currents becomes the main cause for leaks are safely prevented. At the same time an uninterrupted over the entire outer circumference of the container secure contact bridge between the current-conducting layers guaranteed by the cover part and bottom part, so that a optimal long-term protection is achieved.
Dadurch, daß die stromleitende Schicht von Deckelteil und Bodenteil nur jeweils bis zur Mittelebene der Dichtung geführt ist, kann bei besonders ungünstigen Bedingungen bis zur Dichtungsmitte vordringende Feuchtigkeit noch keine in das Behälterinnere reichenden Kriechströme verursachen.The fact that the current-conducting layer of the cover part and Bottom part only up to the middle level of the seal is carried out in particularly unfavorable conditions up to Moisture penetrating the seal does not yet enter the Cause leakage currents reaching inside the container.
Um das Eindringen von Feuchtigkeit bis zur elastischen Dichtung überhaupt zu verhindern, kann in Weiterentwicklung zusätzlich vor der elastischen Dichtung eine außenliegende weitere, nicht elektrisch leitende Dichtung vorgesehen sein.To penetrate moisture to elastic Preventing seal at all can be in further development additionally an external one in front of the elastic seal further, non-electrically conductive seal may be provided.
Weitere erfindungsgemäße Ausbildungen sind den Unteransprüchen zu entnehmen und werden mit ihren Vorteilen anhand der beigefügten einzigen Zeichnung eines bevorzugten Ausführungsbeispiels in der nachstehenden Beschreibung näher erläutert.Further training according to the invention are the dependent claims can be seen and their advantages based on the attached single drawing of a preferred Embodiment in the description below explained.
Ein nur teilweise dargestellter Deckelteil 1 aus faserverstärktem Kunststoff weist einen umlaufenden Randwulst 2 auf, der eine nach unten vorstehende Feder 3 trägt, die in geschlossenem Zustand des Behälters in eine umlaufende Nut 4 eines Bodenteils 5 im ebenfalls umlaufenden Randwulst 6 paßt. Zur Abdichtung ist in der Nut 4 eine Dichtung 7 in Form einer Rundschnurdichtung eingelegt, die beim Aneinanderliegen der Stirnflächen 8 und 9 von Deckelteil 1 und Bodenteil 5 unter Vorspannung abdichtet.An only partially shown cover part 1 made of fiber-reinforced plastic has a circumferential bead 2 , which carries a downwardly projecting spring 3 , which in the closed state of the container fits into a circumferential groove 4 of a bottom part 5 in the circumferential bead 6 . For sealing, a seal 7 in the form of a round cord seal is inserted in the groove 4, which seals when the end faces 8 and 9 of the cover part 1 and base part 5 lie against one another under prestress.
Zur kostengünstigen Gestaltung bei hoher Festigkeit gegen Stöße ist der Randwulst 2 durch Verstärkungseinlagen 10 verstärkt und zwar im Eck- und Kantenbereich.For cost-effective design with high strength against impacts, the edge bead 2 is reinforced by reinforcing inserts 10 , specifically in the corner and edge area.
Auf den Innenflächen von Deckelteil 1 und Bodenteil 5 ist jeweils eine stromleitende Schicht 11 bzw. 12 angeordnet, die über die Stirnflächen 8 bzw. 9 bis zur Mitte von Nut 4 und Feder 3 geführt ist, wie dies gestrichelt in der beigefügten Figur angedeutet ist. Auch ist auf der dem Behälterinneren zugewandten Außenumfangsseite der Dichtung 7 eine weitere stromleitende Schicht 13 vorgesehen, durch die bei geschlossenem Behälter die stromleitenden Schichten 11 und 12 über den ganzen inneren Behälterumfang elektrisch leitend miteinander verbunden sind, so daß das gesamte Behälterinnenvolumen abgeschirmt ist. Die stromleitenden Schichten 11, 12 sind, bspw. durch Metallbedampfung oder aber auch durch Lichtbogenmetallspritzen, vorzugsweise unter Verwendung von Kupfer, hergestellt.On the inner surfaces of cover part 1 and bottom part 5 , a current-conducting layer 11 and 12 is arranged, which is guided over the end faces 8 and 9 to the center of groove 4 and tongue 3 , as indicated by dashed lines in the attached figure. Also provided on the outer circumferential side of the seal 7 facing the inside of the container is a further current-conducting layer 13 , by means of which the current-conducting layers 11 and 12 are electrically conductively connected to one another over the entire inner circumference of the container when the container is closed, so that the entire inner volume of the container is shielded. The current-conducting layers 11 , 12 are produced, for example, by metal vapor deposition or else by arc metal spraying, preferably using copper.
Zur Erzielung einer besonders guten Leitfähigkeit der weiteren stromleitenden Schicht 13 der Dichtung 7 kann deren Innenbereich mit einer Silberbeschichtung versehen sein, die zudem besonders elastisch und auch relativ korrosionsfest ist. Die Verwendung einer Goldbeschichtung wäre bzgl. Korrosionsbeständigkeit und Leitfähigkeit optimal aber auch sehr kostspielig. Zum Korrosionsschutz können zumindest im Bereich des Behälterinneren die stromleitenden Schichten 11, 12 mit einem Oberflächenschutz, bspw. einer Lackschicht, geschützt sein.To achieve a particularly good conductivity of the further current-conducting layer 13 of the seal 7 , the inner region thereof can be provided with a silver coating, which is also particularly elastic and also relatively corrosion-resistant. The use of a gold coating would be optimal in terms of corrosion resistance and conductivity, but would also be very expensive. For corrosion protection, the current-conducting layers 11 , 12 can be protected at least in the region of the interior of the container with a surface protection, for example a lacquer layer.
