Beschreibungdescription
EinschubkartePlug-in card
Die Erfindung betrifft eine Einschubkarte mit einer Leiterplatte und einer Befestigungsvorrichtung, die an einer Seitenkante der Leiterplatte angeordnet ist, mit einem ersten und mindestens einem zweiten Befestigungselement, wobei das erste Befestigungselement an der Leiterplatte befestigt ist und das zweite Befestigungselement mit einem Befestigungsmittel an einem Gehäuse, in das die Einsteckkarte aufgenommen ist, befestigbar ist.The invention relates to a plug-in card with a printed circuit board and a fastening device which is arranged on a side edge of the printed circuit board, with a first and at least a second fastening element, the first fastening element being fastened to the printed circuit board and the second fastening element with a fastening means to a housing, into which the plug-in card is received, can be attached.
Einschubkarten dieser Art sind in vielen elektronischen Gerä- ten vorgesehen, insbesondere in Computern. Bei den Einschubkarten handelt es sich beispielsweise um Schnittstellenkarten, Modems oder Soundkarten. An einer Seite der Leiterplatte sind Kontakte vorgesehen, so dass die Leiterplatte in eine entsprechende Steckerleiste eingeschoben werden kann. Dabei entsteht ein elektrischer und mechanischer Kontakt zwischen der Einschubkarte und einer Häuptplatine, die die Steckerleiste trägt .Plug-in cards of this type are provided in many electronic devices, especially in computers. The plug-in cards are, for example, interface cards, modems or sound cards. Contacts are provided on one side of the printed circuit board so that the printed circuit board can be inserted into a corresponding plug connector. This creates an electrical and mechanical contact between the plug-in card and a main board that carries the power strip.
Die Befestigungsvorrichtung ist in der Regel als eine Metall- schiene ausgebildet, wobei an einem Ende der Schiene ein Winkelstück vorgesehen ist, um die Befestigungsschiene an einem Gehäuse, in das die Einsteckkarte aufgenommen ist, befestigen zu können. Diese Befestigungsschiene ist an einer zweiten Kante der Leiterplatte angeordnet, die senkrecht zu der die Kontakte tragenden Kante steht. Das zweite Befestigungselement in Form des Winkels ist vorzusehen, um eine ausreichende mechanische Stabilität zu erreichen, denn an der Befestigungsvorrichtung sind oft Steckerbuchsen zum Anschluß von Kabeln vorgesehen. Beim Ein- und Ausstecken treten mechanische Kräfte auf, die allein durch die Klemmwirkung der Steckvorrichtung für die elektrische Verbindung der Leiterplatte mit der Hauptplatine nicht aufgefangen werden können. Zudem be- steht die Gefahr, dass durch die Krafteinwirkung die Leiterplatte ganz oder teilweise aus der Steckvorrichtung herausrutscht. Weiterhin kann über die Befestigungsvorrichtung sichergestellt werden, dass die Einschubkarte ganz eingesteckt ist und somit ein zuverlässiger Kontakt an allen Kontaktstellen besteht .The fastening device is generally designed as a metal rail, an angle piece being provided at one end of the rail in order to be able to fasten the fastening rail to a housing in which the plug-in card is received. This mounting rail is arranged on a second edge of the circuit board, which is perpendicular to the edge carrying the contacts. The second fastening element in the form of the angle is to be provided in order to achieve sufficient mechanical stability, since plug sockets for connecting cables are often provided on the fastening device. When plugging in and unplugging, mechanical forces occur that cannot be absorbed solely by the clamping action of the plug-in device for the electrical connection of the circuit board to the main board. In addition, there is a risk that the circuit board will slip out of the plug device in whole or in part due to the force. Furthermore, the fastening device can be used to ensure that the plug-in card is fully inserted and that there is therefore reliable contact at all contact points.
Die Computergehäuse sind in vielen Fällen auf die Größe der Einschubkarten abgestimmt. Dabei hat sich ein gewisses Nor - maß entwickelt, so daß Einschubkarten in alle Standardgehäuse einsetzbar sind. Durch die fortschreitende Entwicklung der Halbleitertechnologie hat sich jedoch im Laufe der Zeit die Größe der Einschubkarten verkleinert, so daß es nun möglich ist, auch kleinere Gehäuse zu verwenden. Folglich hat sich ein zweiter Standard für kleinere Einschubkarten entwickelt. Problematisch ist bei den Einschubkarten der eingangs genannten Art, daß sie nur für eine Standardgröße geeignet sind, obwohl die Größe der Leiterplatte in beiden Fällen gleich ist. Zur Anpassung an den größeren Standard sind lediglich die Befestigungselemente länger ausgeführt. Die Verwendung von Einschubkarten gleicher Funktion mit unterschiedlichen Größen ist jedoch teuer, da bei der Herstellung, dem Transport und der Lagerung zusätzliche Kosten anfallen. Darüber hinaus ergeben sich Probleme bei einem eventuellen Austausch von Komponenten, weil die Ersatzkomponente nicht nur die entsprechende Funktion, sondern auch die entsprechende Größe aufweisen muß.In many cases, the computer housings are matched to the size of the plug-in cards. A certain standard has developed so that plug-in cards can be used in all standard housings. Due to the progressive development of semiconductor technology, the size of the plug-in cards has decreased over time, so that it is now possible to use smaller packages. As a result, a second standard for smaller plug-in cards has developed. The problem with the plug-in cards of the type mentioned is that they are only suitable for a standard size, although the size of the circuit board is the same in both cases. To adapt to the larger standard, only the fastening elements are longer. However, the use of plug-in cards of the same function with different sizes is expensive, since additional costs are incurred in the manufacture, transport and storage. In addition, problems arise when components are replaced, because the replacement component must not only have the appropriate function, but also the appropriate size.
Aufgabe der Erfindung ist es daher, eine Einschubkarte anzu- geben, die bei verschiedenen Gehäusegrößen einsetzbar ist.The object of the invention is therefore to provide a plug-in card which can be used in different housing sizes.
Diese Aufgabe wird durch eine Einschubkarte der eingangs genannten Art gelöst, die dadurch gekennzeichnet ist, daß das erste und das zweite Befestigungselement beweglich miteinan- der verbunden sind. Ebenso wird die Aufgabe gelöst durch eine Einschubkarte der eingangs genannten Art, bei der das erste und das zweite Befestigungselement durch eine Steck- und/oder Klemmverbindung miteinander verbindbar sind oder durch eine Einschubkarte, bei der das erste und das zweite Befes igungs- element einstückig miteinander verbunden und an einer Soll- bruchstelle trennbar sind.This object is achieved by a plug-in card of the type mentioned at the outset, which is characterized in that the first and the second fastening element are movably connected to one another. The object is also achieved by a plug-in card of the type mentioned at the beginning, in which the first and the second fastening element are inserted by a plug-in and / or Clamp connection can be connected to one another or by means of a plug-in card in which the first and the second fastening element are connected to one another in one piece and can be separated at a predetermined breaking point.
Diesen Lösungen liegt der gemeinsame Erfindungsgedanke zugrunde, daß die Befestigungsvorrichtung nicht starr ist, sondern so gestaltet ist, daß die Befestigungsvorrichtung zweiteilig derart gestaltet ist, daß verschiedene Längen der Be- festigungsvorrichtung realisierbar sind.These solutions are based on the common inventive concept that the fastening device is not rigid, but is designed in such a way that the fastening device is designed in two parts in such a way that different lengths of the fastening device can be realized.
Gemäß der ersten Lösung sind die Befestigungselemente beweglich, vorzugsweise über ein Scharnier miteinander verbunden. Das Scharnier ist dabei so angeordnet, daß sich bei dem zwei- ten Befestigungselement ein langer und ein kurzer Teilabschnitt bildet, wobei bei einem kleinen Gehäuse die Befestigungsvorrichtung an dem kurzen Teilabschnitt mit einem Befestigungsmittel am Gehäuse befestigt ist und bei einem großen Gehäuse entsprechend mit dem langen Teilabschnitt.According to the first solution, the fastening elements are movable, preferably connected to one another via a hinge. The hinge is arranged in such a way that a long and a short section is formed in the second fastening element, the fastening device being fastened to the short section with a fastener on the housing in a small housing and correspondingly with the long one in a large housing subsection.
Gemäß der zweiten Lösung sind die beiden Befestigungselemente steckbar miteinander verbunden, wobei durch die Art des Zusammensteckens verschiedene Längen der Befestigungsvorrichtung realisierbar sind.According to the second solution, the two fastening elements are connected to one another in a plug-in manner, with different lengths of the fastening device being able to be realized due to the way in which they are plugged together.
In einer dritten Lösung sind die beiden Befestigungselemente einstückig miteinander verbunden, wobei eine Sollbruchstelle vorgesehen ist, um diese zu trennen. Bei einem großen Gehäuse wird die Befestigungsvorrichtung so verwendet, daß die beiden Befestigungselemente miteinander verbunden sind. Soll jedoch die Einschubkarte in ein kleines Gehäuse eingesetzt werden, können die beiden Befestigungselemente durch eine verhältnismäßig geringe Kraft voneinander getrennt werden und durch Zusammenstecken wieder so verbunden werden, daß die Befesti- gungsvorrichtung nun in einem kleinen Gehäuse einsetzbar ist. Vorteilhaft bei diesen Anordnungen ist, daß sie allesamt ohne großen Aufwand realisierbar sind und somit nur geringe zusätzliche Kosten entstehen. Allerdings wird der Vorteil gewonnen, daß nur noch eine Einschubkarte für verschiedene Grö- ßen vorgesehen werden muß.In a third solution, the two fastening elements are connected to one another in one piece, a predetermined breaking point being provided in order to separate them. In the case of a large housing, the fastening device is used in such a way that the two fastening elements are connected to one another. If, however, the plug-in card is to be inserted into a small housing, the two fastening elements can be separated from one another by a relatively small force and connected again by plugging them together so that the fastening device can now be used in a small housing. The advantage of these arrangements is that they can all be implemented without great effort and thus only result in low additional costs. However, the advantage is gained that only one plug-in card has to be provided for different sizes.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert. Es zeigt:The invention is explained in more detail below on the basis of exemplary embodiments. It shows:

Figuren 6 und 7 ein drittes Ausführungsbeispiel einer erfin- dungsgemäßen Einschubkarte.FIGS. 6 and 7 show a third exemplary embodiment of a plug-in card according to the invention.
Im ersten Ausführungsbeispiel nach Figuren 1 und 2 ist eine Leiterplatte 2 mit einer Befestigungsvorrichtung 1 versehen. Diese ist an einer Kante der Leiterplatte 2 angeordnet. Senk- recht zu dieser Kante befindet sich eine Kante mit Kontaktflächen 7 zum Anschluß der Leiterplatte mittels einer Steckvorrichtung an eine Hauptplatine, die in den Figuren 1 und 2 nicht dargestellt ist (vgl. Figur 3). Die Verbindung zwischen der Befestigungsvorrichtung 1 und der Leiterplatte 2 erfolgt an einem ersten Befestigungselement 3. Dieses erstreckt sich über die Leiterplatte 2 hinaus und ist an dem sich über die Leiterplatte 2 hinaus erstreckenden Ende über ein Scharnier 5 mit einem zweiten Befestigungselement 4 verbunden. Das Scharnier teilt das zweite Befestigungselement 4 in zwei Schenkel, wobei der kurze Schenkel eine Bohrung für ein Befestigungs- mittel 6 in Form beispielsweise einer Schraube aufweist. Der lange Schenkel 4 weist ein winkelförmiges Endstück 8 auf. In der Darstellung von Figur 1 ist das zweite Befestigungselement 4 in eine zum ersten Befestigungselement 3 senkrechte Position geschwenkt. In der dargestellten Lage kann nun die Befestigungsvorrichtung 1 über eine Schraube 6 an einem Gehäuseelement 10 befestigt werden.In the first exemplary embodiment according to FIGS. 1 and 2, a printed circuit board 2 is provided with a fastening device 1. This is arranged on an edge of the printed circuit board 2. Perpendicular to this edge there is an edge with contact surfaces 7 for connecting the printed circuit board by means of a plug device to a main circuit board, which is not shown in FIGS. 1 and 2 (see FIG. 3). The connection between the fastening device 1 and the printed circuit board 2 takes place on a first fastening element 3. This extends beyond the printed circuit board 2 and is connected to a second fastening element 4 via a hinge 5 at the end extending beyond the printed circuit board 2. The hinge divides the second fastening element 4 into two legs, the short leg having a bore for a fastening means 6 in the form of a screw, for example. The long leg 4 has an angular end piece 8. 1, the second fastening element 4 is pivoted into a position perpendicular to the first fastening element 3. In the position shown, the fastening device 1 can now be fastened to a housing element 10 by means of a screw 6.
In der Figur 2 ist die Anordnung von Figur 1 dargestellt, wobei in dieser Darstellung das zweite Befestigungselement 4 so geschwenkt ist, daß es eine Fortsetzung des ersten Befestigungselementes 3 bildet. Während in der Darstellung von Figur 1 ein Winkel dadurch gebildet ist, daß das zweite Befestigungselement 4 senkrecht zum ersten Befestigungselement 3 liegt, entsteht in der Figur 2 der Winkel dadurch, daß das eine Ende des zweiten Befestigungselementes 4 als Winkelstück 8 ausgebildet ist. Allerdings ist in der Figur 2 der Abstand des Winkelstücks 8 von der Kante mit den Kontakten 7 wesentlich größer als in der Darstellung von Figur 1 der Abstand zwischen dem Befestigungspunkt und den Kontaktfläche 7. Bei der Verwendung nach Figur 1 ist die Einschubkarte für Gehäuse nach dem „kleinen" Standard, bei Verwendung nach Figur 3 für Gehäuse nach dem „großen" Standard geeignet. In beiden Figuren ist gestrichelt ein Teil des Gehäuses 10 angedeutet, an dem die Befestigungsvorrichtung 1 mit dem Befestigungsmittel 6 fixiert werden kann.The arrangement of FIG. 1 is shown in FIG. 2, the second fastening element 4 being pivoted in this representation such that it forms a continuation of the first fastening element 3. 1, an angle is formed by the fact that the second fastening element 4 is perpendicular to the first fastening element 3, in FIG. 2 the angle is formed by the fact that one end of the second fastening element 4 is designed as an angle piece 8. However, in Figure 2, the distance of the angle piece 8 from the edge with the contacts 7 is significantly larger than in the representation of Figure 1, the distance between the attachment point and the contact surface 7. When used according to Figure 1, the plug-in card for housing after "Small" standard, when used according to Figure 3 suitable for housings according to the "large" standard. In both figures, part of the housing 10 is indicated by dashed lines, on which the fastening device 1 can be fixed with the fastening means 6.
In der Figur 3 ist eine dreidimensionale Darstellung der Anordnung der Figuren 1 und 2 gezeigt. Die Leiterplatte 2 der Einschubkarte ist mit den Kontakten 7 in einer Steckleiste 12 auf einer Hauptplatine 15 aufgenommen. An dem ersten Befestigungselement 3 ist eine Steckerbuchse 16 vorgesehen, in die beispielsweise ein Druckerkabel eingesteckt werden kann. Die beim Einstecken auftretenden Kräfte werden durch eine Befestigung des zweiten Befestigungselementes 4 an einem Gehäuse- teil abgefangen, wobei zur Übersichtlichkeit der Darstellung das Gehäuse nicht dargestellt ist. Die Befestigung erfolgt aber so, wie in den Figuren 1 und 2 gezeigt In einem zweiten Ausführungsbeispiel gemäß den Figuren 4 und 5 ist eine Befestigungsvorrichtung 11 aus zwei Befestigungselementen 13 und 14 zusammengesetzt, wobei die beiden Befe- stigungselemente 13 und 14 durch Stecken miteinander verbindbar sind. Das zweite Befestigungselement 14 ist auch in diesem Fall im wesentlichen winkelförmig gestaltet, wobei im Fall eines großen Gehäuses der lange Schenkel des Winkels parallel zur Längserstreckung des ersten Befestigungselemen- tes 13 liegt und durch Stecken mit diesem verbunden ist, und im zweiten Fall der lange Schenkel des Winkels senkrecht auf dem Befestigungselement 13 steht. In diesem Fall erfolgt die Befestigung mit der Schraube 6 an dem langen Schenkel, während im Fall des großen Gehäuses die Schraube 6 am kurzen Schenkel eingesetzt wird.FIG. 3 shows a three-dimensional representation of the arrangement of FIGS. 1 and 2. The circuit board 2 of the plug-in card is received with the contacts 7 in a plug-in strip 12 on a main board 15. A connector 16 is provided on the first fastening element 3, into which, for example, a printer cable can be inserted. The forces occurring during insertion are intercepted by fastening the second fastening element 4 to a housing part, the housing not being shown for the sake of clarity of illustration. The attachment takes place as shown in Figures 1 and 2 In a second exemplary embodiment according to FIGS. 4 and 5, a fastening device 11 is composed of two fastening elements 13 and 14, the two fastening elements 13 and 14 being connectable to one another by plugging. In this case too, the second fastening element 14 is essentially of an angular shape, the long leg of the angle lying parallel to the longitudinal extent of the first fastening element 13 and being connected to it by plugging in the case of a large housing, and the long leg in the second case of the angle is perpendicular to the fastener 13. In this case, the screw 6 is attached to the long leg, while in the case of the large housing, the screw 6 is used on the short leg.
In einem dritten Ausführungsbeispiel gemäß den Figuren 6 und 7 sind Befestigungselemente 23 und 24 der Befestigungsvorrichtung 21 zunächst einstückig miteinander verbunden. Zwi- sehen den Befestigungselementen 23 und 24 besteht jedoch eineIn a third exemplary embodiment according to FIGS. 6 and 7, fastening elements 23 and 24 of the fastening device 21 are initially connected to one another in one piece. Between the fasteners 23 and 24, however, there is one
Sollbruchstelle 26, an der die beiden Befestigungselemente 23 und 24 getrennt werden können. Im ursprünglichen einstückigen Zustand ist die Befestigungsvorrichtung 21 für ein großes Gehäuse geeignet. Wenn jedoch ein kleines Gehäuse verwendet werden soll, so läßt sich die Befestigungsvorrichtung 21 an der Sollbruchstelle 26 in zwei Teile trennen. Eine solche Sollbruchstelle kann auf Zug relativ stark belastet werden, so daß im normalen Einsatz eine ausreichende Stabilität be- steht. Erst bei Beanspruchung auf Biegung läßt sich ein Bre- chen an dieser Stelle mit relativ geringem Kraftaufwand realisieren.Predetermined breaking point 26 at which the two fastening elements 23 and 24 can be separated. In the original one-piece state, the fastening device 21 is suitable for a large housing. However, if a small housing is to be used, the fastening device 21 can be separated into two parts at the predetermined breaking point 26. Such a predetermined breaking point can be loaded relatively heavily on train, so that there is sufficient stability in normal use. Breaking at this point can only be achieved with relatively little effort when stress is applied to bending.
Am ersten Befestigungselement 23 bleibt eine Nase 22 stehen. Am zweiten Befestigungselement 24 ist eine Ausnehmung 25 vor- gesehen, deren Größe auf die Nase 22 abgestimmt ist. Nach dem Trennen der Befestigungselemente 23 und 24 lassen sich daher die beiden Befestigungselemente wieder durch Stecken mitein- ander verbinden. Dadurch entsteht, wie auch in den ersten beiden Ausführungsbeispielen der Figuren 1 bis 3 bzw. 4 und 5 eine verkürzte Befestigungsvorrichtung, wobei sowohl in der langen als auch in der kurzen Variante ein Winkel gebildet ist, über den eine Befestigung an einem Gehäuselement 10 erfolgen kann.A nose 22 remains on the first fastening element 23. A recess 25 is provided on the second fastening element 24, the size of which is matched to the nose 22. After separating the fasteners 23 and 24, the two fasteners can therefore be plugged in again. connect others. As in the first two exemplary embodiments of FIGS. 1 to 3 or 4 and 5, this results in a shortened fastening device, an angle being formed both in the long and in the short variant, by means of which an attachment to a housing element 10 can take place ,
Die Ausführung der Figuren 6 und 7 hat den Vorteil, daß sie besonders einfach zu realisieren ist. Nachteilig ist ledig- lieh, daß es sich bei dem Brechen an der Sollbruchstelle 26 um einen irreversiblen Vorgang handelt, so daß die Einschubkarte, die eine solche Befestigungsvorrichtung 21 aufweist, nachfolgend nicht wieder in einem großen Gehäuse eingesetzt werden kann, ohne daß die Befestigungsvorrichtung 21 erneuert wird. The embodiment of Figures 6 and 7 has the advantage that it is particularly easy to implement. The disadvantage is that the breaking at the predetermined breaking point 26 is an irreversible process, so that the plug-in card, which has such a fastening device 21, cannot subsequently be reinserted in a large housing without the fastening device 21 is renewed.
