Halte- und Kontaktiervorrichtung
5Holding and contacting device

Die Erfindung betrifft eine Halte- und Kontaktiervorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a holding and contacting device according to the features of the preamble of claim 1.
Tischrechner, sog. Desktop-Personalcomputer, sind im allgemeinen so aufgebaut, daß auf einer parallel zur Gehäusebodenplatte verlaufenden System-Flachbaugruppe je nach Ausbaustufe ein oder mehrere CPU- und/oder Speicher-Flachbaugruppen über jeweils zugeordnete Steckerleisten in einer senkrecht zur System-Flachbaugruppe stehenden Position angeordnet werden.Desktop computers, so-called desktop personal computers, are generally designed in such a way that, depending on the level of expansion, one or more CPU and/or memory modules are arranged on a system flat module running parallel to the base plate of the housing via assigned connector strips in a position perpendicular to the system flat module.
Die Befestigung der senkrecht stehenden Flachbaugruppen allein über die an der Unterseite vorgesehene Steckerleiste ist insbesondere aufgrund der mechanischen Belastung des Steckers nicht unproblematisch, andererseits sind zusätzliche seitliche Führungen an den Gehäuseinnenwänden nicht ohne weiteres realisierbar, weil diese Flachbaugruppen im Regelfall geringere Abmessungen im Vergleich zum Abstand zwischen den beiden Gehäusewänden aufweisen. Neben dem Bedürfnis nach einer verbesserten Stabilität ist es insbesondere im Hinblick auf eine Reduzierung der Störstrahlung elektronischer 5 Flachbaugruppen wünschenswert, für diese Flachbaugruppen zusätzlich zum Masseanschluß über die Steckerleiste wenigstens einen weiteren Masseanschluß vorzusehen.The fastening of the vertical printed circuit boards using only the plug strip provided on the underside is not without problems, particularly due to the mechanical load on the plug. On the other hand, additional lateral guides on the inside walls of the housing are not easily implemented because these printed circuit boards are usually smaller than the distance between the two housing walls. In addition to the need for improved stability, it is desirable, particularly with a view to reducing the interference from electronic printed circuit boards, to provide at least one additional ground connection for these printed circuit boards in addition to the ground connection via the plug strip.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Halte- und Kontaktiervorrichtung der im Oberbegriff des Anspruchs 1 angegebenen Art so auszubilden, daß sie sowohl hinsichtlich der mechanischen Stabilität, als auch in bezug auf einen möglichst optimalen Massekontakt hohen Ansprüchen genügt. Die Lösung dieser Aufgabe ergibt sich erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. VorteilhafteThe present invention is therefore based on the task of designing a holding and contacting device of the type specified in the preamble of claim 1 in such a way that it meets high requirements both in terms of mechanical stability and in terms of the most optimal possible ground contact. The solution to this task is achieved according to the invention by the features specified in the characterizing part of claim 1. Advantageous

Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Further developments of the invention are specified in the subclaims.
Im folgenden wird ein Ausführugnsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Dabei zeigenIn the following, an embodiment of the invention is explained in more detail with reference to the drawing.
Figur 1 eine Halte- und Kontaktiervorrichtung gemäß der Erfindung in perspektivischer Darstellung (Ausschnitt), Figur 2 die Einzelheit A aus Figur 1 in vergrößertem Maßstab, Figur 3 die Vorrichtung gemäß Figur 1 in einer Schnittdarstellung. Figure 1 shows a holding and contacting device according to the invention in a perspective view (detail), Figure 2 shows detail A from Figure 1 on an enlarged scale, Figure 3 shows the device according to Figure 1 in a sectional view.
Die Figuren 1 und 2 zeigen einen Ausschnitt aus einer senkrecht angeordneten Leiterplatte 1, die an der nicht dargestellten Unterkante über eine Steckerleiste mit einer horizontal angeordneten System-Flachbaugruppe verbunden ist. Die gesamte Anordnung befindet sich inerhalb eines wannenartigen Gehäuses, wobei die Leiterplatte 1 zwischen zwei einander gegenüberliegenden Gehäusewänden verläuft. Im Bereich der 0 Oberkante der Leiterplatte 1 verläuft eine parallel zur Leiterplatte 1 angeordnete Kontaktschiene 2, die ein. L-Profil aufweist und an gegenüberliegenden Gehäusewänden befestigt ist. Am parallel zu Ebene der Leiterplatte 1 verlaufenden freien L-Schenkel der Kontaktschiene 2 sind wenigstens zwei ' gabelartige Haltebügel 3 und unmittelbar neben diesen Haltebügeln 3 jeweils Kontaktelemente 4 vorgesehen. Das Kontaktelemente 4 besteht aus einem am L-Schenkel der Kontaktschiene 2 angeformten, nach oben offenen U-Bügel, dessen freier U-Schenkel an einer im Bereich der Oberkante der Leiterplatte vorgesehenen Kontaktfläche 6 anliegt. Zur Erzielung einer ausreichenden Federwirkung ist am freien U-Schenkel des Kontaktelements 4 eine etwa S-ähnliche Blattfeder 5 befestigt, derart, daß eine S-Schleife klammerartig auf dem freien U-Schenkel des Kontaktelements· 4 aufgesetzt ist, während das freie Ende der anderen, nach oben offenen S- . Schleife federnd an der Kontaktfläche 6 anliegt. Die offeneFigures 1 and 2 show a section of a vertically arranged circuit board 1, which is connected to a horizontally arranged system flat module via a connector strip at the lower edge (not shown). The entire arrangement is located within a trough-like housing, with the circuit board 1 running between two opposing housing walls. In the area of the upper edge of the circuit board 1, a contact rail 2 runs parallel to the circuit board 1, which has an L-profile and is attached to opposite housing walls. At least two fork-like retaining brackets 3 are provided on the free L-leg of the contact rail 2, which runs parallel to the plane of the circuit board 1, and contact elements 4 are provided directly next to these retaining brackets 3. The contact element 4 consists of a U-bracket that is molded onto the L-leg of the contact rail 2 and is open at the top, the free U-leg of which rests on a contact surface 6 provided in the area of the upper edge of the circuit board. To achieve a sufficient spring effect, an approximately S-shaped leaf spring 5 is attached to the free U-leg of the contact element 4, in such a way that an S-loop is placed like a clamp on the free U-leg of the contact element 4, while the free end of the other S-loop, which is open at the top, rests resiliently on the contact surface 6. The open
&dgr;'&agr; 5 6δ'α 5 6
S-Schleife der Blattfeder 5 ist vorzugsweise in mehrere Federzungen unterteilt.S-loop of the leaf spring 5 is preferably divided into several spring tongues.
Beim Aufsetzen deer Kontaktschiene 2 auf die Leiterplatte 1 greifen die Haltebügel 3 gabelartig über die Oberkante der Leiterplatte 1, während sich die seitlich daneben angeordneten Kontaktelemente 4 mit den aufgesetzten Blattfedern 5 an die Kontaktfläche 6 der Leiterplatte 1 anschmiegen. Durch die gabelartigen Haltebügel 3, deren Halteschlitze im Einsteckbereich konisch aufgeweitet sind, wird die Leiterplatte 1 ausreichend fixiert. Durch das unmittelbar neben dem Haltebügel 3 angeordnete Kontaktelement 4 wird die Leiterplatte 1 nicht nur kontaktiert, sondern auch spielfrei gehalten. Diese zweifache Fuktion der Kontaktschiene 2 wird insbesondere durch die in Figur 3 dargestellte Schnittzeichnung erkennbar, wo die im Schlitz des Haltebügels 3 geführte Leiterplatte 1 durch die Andruckkraft der Blattfeder 5 gegen eine der beiden Schlitzwände gedrückt und damit spielfrei gehalten wird.When the contact rail 2 is placed on the circuit board 1, the retaining brackets 3 grip the upper edge of the circuit board 1 in a fork-like manner, while the contact elements 4 arranged to the side with the attached leaf springs 5 cling to the contact surface 6 of the circuit board 1. The circuit board 1 is sufficiently fixed by the fork-like retaining brackets 3, whose retaining slots are conically widened in the insertion area. The contact element 4 arranged directly next to the retaining bracket 3 not only contacts the circuit board 1, but also holds it free of play. This dual function of the contact rail 2 can be seen in particular in the sectional drawing shown in Figure 3, where the circuit board 1 guided in the slot of the retaining bracket 3 is pressed against one of the two slot walls by the pressure force of the leaf spring 5 and is thus held free of play.
