Description
Die Erfindung betrifft eine Metall-Fixiermaterial-Durchführung, Im Einzelnen mit den Merkmalen aus dem Oberbegriff des Anspruchs 1; ferner ein Verfahren zur Fertigung eines Grundkörpers einer Metall-Fixiermaterial-Durchführung, Im Einzelnen mit den Merkmalen aus dem Oberbegriff von Anspruch 34.The invention relates to a metal fixing material implementation, in detail with the features of the preamble of
Metall-Fixiermaterial-Durchführungen sind in verschiedenen Ausführungen Im Stand der Technik vorbekannt. Darunter versteht man vakuumdichte Verschmelzungen von Fixiermateriallen, Insbesondere Gläsern In Metallen, Die Metalle fungieren dabei als elektrische Lelter. Stellvertretend wird dabei auf
Der Erfindung liegt daher die Aufgabe zugrunde, eine Metall-Fixiermaterial-Durchführung der eingangs genannten Art derart zu gestalten, dass diese durch eine hohe Festigkeit mit geringem Material- und Arbeitsaufwand und der Eignung für höhere Belastungen charakterisiert ist und ferner Montagefehler, die sich durch die ungenaue Zuordnung der einzelnen Elemente ergeben, vermieden werden. Die erfindungsgemäße Lösung ist durch die Merkmale des Anspruches 1 charakterisiert. Die verfahrensmäßige Umsetzung zur Herstellung eines Grundkörpers ist in Anspruch 34 beschrieben. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen wiedergegeben.
Die Metall-Fixiermaterial-Durchführung umfasst einen metallischen Grundkörper, durch den wenigstens ein Metallstift durchgeführt ist. Sind in einer bevorzugten Ausführungsform zwei Metallstifte vorgesehen, so stellt einer der beiden wenigstens mittelbar, d. h. direkt oder indirekt über weitere Elemente die Masseverbindung zum Grundkörper her. Bei Ausführung mit zwei Metallstiften sind diese Metallstifte bevorzugt parallel zueinander angeordnet. Wenigstens einer der Metallstifte ist dabei in einer Durchgangsöffnung im Grundkörper angeordnet und gegenüber diesem durch Fixiermaterial, vorzugsweise in Form eines Glaspfropfens, fixiert. Erfindungsgemäß wird der Grundkörper von einem Blechelement gebildet, wobei die Durchgangsöffnung eine aus dem Grundkörper ausgestanzte Öffnung ist. Der Grundkörper selbst wird bevorzugt ebenfalls aus einem Vollmaterial ausgestanzt, die Endgeometrie des Grundkörpers aber durch einen Umformprozess bspw. Tiefziehen erhalten. In einer bevorzugten Ausführungsform wird auch bereits die äußere Kontur beschreibende Endgeometrie und die die Durchgangsöffnung beschreibende Grundgeometrie wenigstens durch einen Trennvorgang, insbesondere Stanzen, erzeugt. Endgeometrie bedeutet, dass an dieser keine Umformvorgänge mehr vorgenommen werden müssen. Grundgeometrie bedeutet, dass diese entweder bei keinerlei erforderlichen weiteren Änderungen die Endgeometrie darstellt oder an dieser noch Veränderungen durch weitere Fertigungsverfahren, insbesondere Umformverfahren vorgenommen werden können, wobei die Endgeometrie erst nach diesen zusätzlichen Verfahren erzielt wird. Zwischen Vorderseite und Rückseite sind Mittel zur Vermeidung einer Relativbewegung von Fixiermaterial in Richtung der Rückseite gegenüber dem Innenumfang der Durchgangsöffnung vorgesehen. Die Mittel sind integraler Bestandteil des Grundkörpers oder bilden mit diesem eine bauliche Einheit.
Die Erzeugung der Geometrie durch einen Trennvorgang bedeutet, dass die Endgeometrie am Außenumfang des Grundkörpers durch Ausschneiden und die Geometrie der Durchgangsöffnung durch Lochen hergestellt wird. Um die sich daraus ergebende Problematik beim Einschmelzen des einzelnen Metallstiftes in einer Durchgangsöffnung und ferner die Sicherheit gegenüber einem Austreten der Einheit Fixiermaterial und Metallstift in den Griff zu bekommen, sind die Mittel zur Vermeidung einer Relativbewegung von Fixiermaterial in Richtung der Rückseite gegenüber dem Innenumfang der Durchgangsöffnung vorgesehen. Diese fungieren quasi als Widerhaken und führen bei Relativbewegung in Richtung Rückseite zu einem Formschlusses zwischen Fixiermaterialpfropfen, insbesondere Glaspfropfen und Grundkörper. Diese umfassen beispielsweise wenigstens eine örtliche Verengung in der Durchgangsöffnung, wobei diese im gesamten Bereich des Innenumfanges, ausgenommen an der Vorderseite des Grundkörpers vorgesehen werden kann.Metal fuser feedthroughs are variously known in the prior art. This refers to vacuum-tight fusions of Fixiermateriallen, especially glasses in metals, the metals act as electric Lelter. Deputy becomes thereby on
The invention is therefore based on the object to make a metal-fixing material implementation of the type mentioned in such a way that it is characterized by a high strength with low material and labor costs and the suitability for higher loads and also assembly errors caused by the Inaccurate assignment of the individual elements result, be avoided. The solution according to the invention is characterized by the features of
The metal fixing material lead-through comprises a metallic base body through which at least one metal pin is made. If, in a preferred embodiment, two metal pins are provided, one of the two makes at least indirectly, ie directly or indirectly via further elements, the ground connection to the main body. When executed with two metal pins these metal pins are preferably arranged parallel to each other. At least one of the metal pins is arranged in a passage opening in the base body and fixed relative thereto by fixing material, preferably in the form of a glass plug. According to the invention, the base body is formed by a sheet metal element, wherein the passage opening is an opening punched out of the base body. The main body itself is preferably likewise punched out of a solid material, but the final geometry of the basic body is obtained by a forming process, for example deep-drawing. In a preferred embodiment, even the outer geometry describing the outer contour and the basic geometry describing the passage opening are produced at least by a separation process, in particular punching. End geometry means that no forming operations have to be performed on it. Basic geometry means that it does not represent the final geometry in the event of any further changes required, or that changes can still be made to this by further production processes, in particular forming processes, the final geometry being achieved only after these additional processes. Between front and back means are provided for preventing a relative movement of fixing material in the direction of the rear side relative to the inner circumference of the passage opening. The funds are an integral part of the body or form a structural unit with this.
The generation of the geometry by a separation process means that the final geometry on the outer circumference of the base body is made by cutting and the geometry of the through hole by punching. In order to get the resulting problem when melting the single metal pin in a through hole and also to ensure the security against leakage of the unit fixing material and metal pin in the handle, the means for preventing relative movement of fixing material in the direction of the back against the inner circumference of the through hole intended. These act as a kind of barbs and lead with relative movement in the direction of the back to a positive connection between Fixiermaterialpfropfen, in particular glass plug and body. These include, for example, at least one local constriction in the passage opening, which can be provided in the entire region of the inner circumference, except at the front of the body.
Die erfindungsgemäße Lösung ermöglicht es zum einen auf kostengünstigere Herstellungsverfahren und Ausgangsmaterialien zurückzugreifen, wobei der Materialeinsatz erheblich minimiert wird. Ferner kann der gesamte Grundkörper als integrales Bauteil ausgebildet sein, in welches der Metallstift mittels Fixiermaterial eingeschmolzen wird. Ein weiterer wesentlicher Vorteil besteht darin, dass auch unter erhöhten Belastungen auf den einzelnen Metallstift, zum Beispiel einer Druckbelastung, ein Herausdrücken des Metallstiftes mit dem Glaspfropfen aus der Durchgangsöffnung sicher vermieden wird. Die gesamte Ausführung baut ferner in der Breite kleiner und ist bei geringerer Baugröße durch die Gewährleistung der sicheren Fixierung des Metallstiftes im Grundkörper auch bei höheren Kräften geeignet.The solution according to the invention makes it possible, on the one hand, to resort to more cost-effective production methods and starting materials, wherein the use of material is considerably minimized. Furthermore, the entire base body may be formed as an integral component, in which the metal pin is fused by means of fixing material. Another significant advantage is that even under increased loads on the individual metal pin, for example a pressure load, a pressing out of the metal pin with the glass plug from the through hole is reliably avoided. The entire design also builds smaller in width and is suitable for smaller size by ensuring the secure fixation of the metal pin in the body even at higher forces.
Entscheidend ist dabei, dass die örtliche Verengung des Querschnittes im Bereich der Rückseite oder aber zwischen Rückseite und Vorderseite erfolgt, wobei jedoch die Vorderseite immer durch einen größeren Durchmesser charakterisiert ist.It is crucial that the local narrowing of the cross section takes place in the region of the back or between the back and the front, but the front side is always characterized by a larger diameter.
Gemäß einer besonders vorteilhaften Ausgestaltung ist der zweite Metallstift als Massestift an der Rückseite des Grundkörpers auf Masse gelegt bzw. befestigt. Damit entfallen zusätzliche Maßnahmen, um einen im Grundkörper mit Fixiermaterial fixierten Metallstift auf Masse zu legen bzw. elektrisch mit dem Grundkörper zu koppeln. Ferner ist nur noch ein Stift in einer Durchgangsöffnung zu fixieren, wobei die Möglichkeiten damit vielfältiger werden, den einzelnen Stift vollständig in Umfangsrichtung sicher zu fixieren und die mögliche Anbindungsfläche für den Massestift kann vergrößert werden.According to a particularly advantageous embodiment, the second metal pin is grounded or fixed as a ground pin on the back of the body. This eliminates additional measures to put a fixed in the base body with fixing metal pin to ground or to electrically couple with the body. Furthermore, only a pin is to be fixed in a through hole, the possibilities are thus more diverse, completely secure the individual pin in the circumferential direction and the possible connection surface for the ground pin can be increased.
Als Fixiermaterial findet beispielsweise ein Glaspfropfen, ein Keramikpfropfen, ein Glaskeramikpfropfen oder ein Hochleistungspolymer Verwendung.The fixing material used is, for example, a glass plug, a ceramic plug, a glass ceramic plug or a high-performance polymer.
Für die konkrete Ausgestaltung der Mittel zur Verhinderung einer Relativbewegung zwischen Fixiermaterial und Durchgangsöffnung, insbesondere des Herausgleitens, bestehen eine Mehrzahl von Möglichkeiten. Diese sind durch Maßnahmen am Grundkörper charakterisiert. Im einfachsten Fall wird auf Maßnahmen am Grundkörper zurückgegriffen, die bei der Fertigung, insbesondere beim Stanzvorgang, mit realisiert werden können. Dabei zeichnet sich die Durchgangsöffnung zwischen Rückseite und Vorderseite durch eine Änderung des Querschnittsverlaufes aus. Im einfachsten Fall sind wenigstens zwei Bereiche unterschiedlicher Innenabmessungen, bei Ausführung als Durchgangsöffnung mit kreisrundem Querschnitt mit unterschiedlichem Durchmesser vorgesehen. Die Querschnittsänderung kann dabei in Stufen oder aber stetig erfolgen. Im letztgenannten Fall ist die Durchgangsöffnung zwischen Vorder- und Rückseite konisch ausgestaltet, wobei diese sich zur Rückseite hin verengt.
Die Maßnahmen am Grundkörper sind in der Regel des Weiteren durch das Vorsehen von mehreren Ausnehmungen bzw. Vorsprüngen charakterisiert. Diese bilden wenigstens eine von der Rückseite ausgehend betrachtet am Innenumfang der Durchgangsöffnung im Grundkörper zwischen Rückseite und Vorderseite angeordnete Hinterschneidung, wobei die Vorderseite frei von derartigen Hinterschneidungen ist. Bei symmetrischer Ausführung der Durchgangsöffnung ist diese durch drei Teilbereiche charakterisiert - einen ersten Teilbereich, der sich von der Rückseite in Richtung Vorderseite erstreckt, einen zweiten sich daran anschließenden und einen dritten Teilbereich, der sich von Vorderseite in Richtung Rückseite erstreckt. Der zweite Teilbereich ist durch geringere oder größere Abmessungen der Durchgangsöffnung als der erste und dritte Teilbereich charakterisiert. Vorzugsweise sind dann der erste und dritte Teilbereich durch identische Querschnittsabmessungen charakterisiert.For the specific embodiment of the means for preventing a relative movement between the fixing material and the passage opening, in particular the sliding out, there are a plurality of possibilities. These are characterized by measures on the body. In the simplest case will open Measures taken at the base body, which can be realized in the production, especially during the punching process, with. In this case, the passage opening between the back and front is characterized by a change in the cross-sectional profile. In the simplest case, at least two regions of different internal dimensions are provided, when designed as a passage opening with a circular cross-section with a different diameter. The change in cross section can be done in stages or continuously. In the latter case, the passage opening between the front and rear side is conical, which narrows towards the rear.
The measures on the main body are usually further characterized by the provision of a plurality of recesses or projections. These form at least one from the back viewed on the inner circumference of the through hole in the base between the back and front arranged undercut, the front is free of such undercuts. In the case of a symmetrical design of the passage opening, this is characterized by three partial areas - a first partial area which extends from the rear side in the direction of the front side, a second adjoining area and a third partial area which extends from the front side to the rear side. The second partial area is characterized by smaller or larger dimensions of the passage opening than the first and third partial area. Preferably, the first and third subareas are then characterized by identical cross-sectional dimensions.
Bei Ausführungen mit mehr als zwei Bereichen unterschiedlicher Abmessungen, insbesondere unterschiedlichen Durchmessers werden Verfahren gewählt, die durch beidseitige Bearbeitung des Grundkörpers entstehen. Wird bei den vorher beschriebenen Ausführungen auf eine asymmetrische Gestaltung der Durchgangsöffnung abgestellt, so wird bei diesen Ausführungen mit mehr als zwei Bereichen vorzugsweise eine Ausgestaltung der Durchgangsöffnung gewählt, die hinsichtlich der Einbauposition beliebig verwendbar ist. Diese ist, bezogen auf eine theoretische Mittenachse, die senkrecht zur Stiftachse des im Grundkörper geführten Stiftes verläuft und sich im Mittenbereichs des Grundkörpers erstreckt, symmetrisch ausgebildet. Damit können Vorder- und Rückseite hinsichtlich ihrer Funktion auch vertauscht werden. Die durch diese gebildeten Hinterschneidungen wirken möglichen Bewegungen des Fixiermaterialpfropfens in beide Richtungen entgegen.In embodiments with more than two areas of different dimensions, in particular different diameters, methods are selected which are created by machining the base body on both sides. If, in the previously described embodiments, an asymmetrical design of the passage opening is turned off, in these embodiments, with more than two areas, an embodiment of the passage opening is preferably selected which can be used with regard to the installation position. This is, based on a theoretical center axis which is perpendicular to the pin axis of the guided in the main body pin and extending in the central region of the body, formed symmetrically. This front and back can also be reversed in terms of their function. The undercuts formed by these counteract possible movements of the Fixiermaterialpfropfens in both directions.
Gemäß einer weiteren Ausgestaltung können auch eine Mehrzahl von in Umfangsrichtung zueinander beabstandet auf einer gemeinsamen Länge zwischen Vorder- und Rückseite angeordneten Vorsprüngen vorgesehen sein. Diese werden in der Regel durch Prägen, d. h. örtliche Verformung unter Druck im Bereich der Rückseite erzeugt. Das Herstellungsverfahren ist somit besonders kostengünstig.According to a further embodiment, a plurality of circumferentially spaced from each other on a common length between the front and rear projections arranged can be provided. These are usually embossed, d. H. local deformation under pressure generated in the area of the back. The production process is thus particularly cost-effective.
Eine weitere Möglichkeit zur Vermeidung von Relativbewegungen zwischen Fixiermaterialpfropfen und Durchgangsöffnung besteht in der Ausbildung einer kraftschlüssigen Verbindung zwischen diesen. Normalerweise wird bspw. das Glas zusammen mit dem Metallstift in die Öffnung eingebracht, Glas und Metallring erwärmt, so dass nach dem Abkühlen das Metall auf den Glaspfropfen aufschrumpft. Im allgemeinen weist die Durchgangsöffnung nach dem Stanzen der Durchgangsöffnung im wesentlichen den Enddurchmesser auf. Natürlich kann die gestanzte Durchgangsöffnung selbst noch bearbeitet werden, beispielsweise geschliffen werden, ohne dass sich der Enddurchmesser wesentlich ändert. Die Durchgangsöffnung kann einen kreisrunden Querschnitt aufweisen. Andere Möglichkeiten sind denkbar, beispielsweise ein ovaler Querschnitt..Another way to avoid relative movements between Fixiermaterialpfropfen and through hole is the formation of a positive connection between them. Normally, for example, the glass is introduced into the opening together with the metal pin, and the glass and metal ring are heated, so that after cooling, the metal shrinks onto the glass plug. In general, the passage opening after punching the passage opening substantially to the final diameter. Of course, the punched through hole itself can still be edited, for example, be ground without the end diameter changes significantly. The passage opening may have a circular cross-section. Other possibilities are conceivable, for example an oval cross section.
Gemäß einer vorteilhaften Weiterentwicklung sind zur zusätzlichen Vermeidung von Relativbewegungen unter Last zwischen Metallstift und Fixiermaterial Maßnahmen am Metallstift vorgesehen. Dabei kann es sich jeweils um sich über den gesamten Außenumfang des Metallstiftes erstreckende Vorsprünge bzw. Ausnehmungen handeln oder aber um in Umfangsrichtung zueinander benachbart mit beliebigen oder fest vordefinierten und fest angeordneten Vorsprünge.According to an advantageous development, measures are provided on the metal pin for additional avoidance of relative movements under load between metal pin and fixing material. These may each be protrusions or recesses extending over the entire outer circumference of the metal pin, or they may be adjacent to one another in the circumferential direction with any desired or fixed predefined and fixed projections.
Das Verfahren zur Herstellung eines Grundkörpers einer Metall-Durchführung ist dadurch charakterisiert, dass die die äußere Geometrie beschreibende Endkontur durch einen Trennvorgang frei von spannender Bearbeitung aus einem Blechteil vordefiniertre Dicke gewonnen wird. Ebenso erfolgt die Erzielung der die Ausgangsform der Durchgangsöffnung beschreibenden Grundgeometrie zur Bildung der Durchgangsöffnung für mindestens einen Metallstift durch Ausstanzen aus dem Blechteil. Dabei können beide Vorgänge in kostensparender Weise in ein Werkzeug und einen Arbeitsgang verlegt werden. Die Hinterschneidungen in den Durchgangsöffnungen werden durch Verformung der Durchgangsöffnung gebildet, beispielsweise Prägen. Der einzelne Prägevorgang kann dabei vor oder nach dem Stanzvorgang vorgenommen werden. Vorzugsweise erfolgen Präge- und Stanzvorgang jeweils an der gleichen Seite des Grundkörpers, um unnötige Werkstückpositionsveränderungen zu vermeiden und eventuelle diese Verfahren unmittelbar hintereinander ablaufen zu lassen.The method for producing a main body of a metal bushing is characterized in that the outer contour describing the final contour is obtained by a separation process free of exciting machining of a sheet metal predefined thickness. Likewise, the achievement of the basic shape of the passage opening descriptive basic geometry to form the passage opening for at least one metal pin by punching out of the sheet metal part. Both processes can be laid in a cost-saving manner in a tool and a single operation. The undercuts in the through holes are formed by deformation of the through hole, for example embossing. The individual embossing process can be carried out before or after the punching process. Preferably, embossing and punching are carried out in each case on the same side of the body in order to avoid unnecessary changes in the workpiece position and to allow any of these processes to take place immediately after one another.
Entsprechend der gewünschten zu erzielenden Geometrien erfolgen die Prägevorgänge einseitig oder beidseitig, wobei im letztgenannten Fall vorzugsweise gleiche Prägeparameter eingestellt werden, um eine symmetrische Ausführung der Durchgangsöffnung zu gewährleisten.According to the desired geometries to be achieved, the embossing operations are carried out on one side or both sides, wherein in the latter case preferably the same embossing parameters are set in order to ensure a symmetrical design of the passage opening.
