Vorrichtung zur Befestigung von auswechselbaren SchaltungsplattenDevice for fastening interchangeable circuit boards
Die Neuerung bezieht sich auf eine Vorrichtung zur Befestigung von auswechselbare Schaltungsplatten tragenden Haltebügeln in Nachrichtengeraten.The innovation relates to a device for attaching interchangeable circuit boards supporting brackets in communication devices.
Derartige Haltebügel werden zum Beispiel in der Modulbauweise in Nachrichtengeräte verwendet, indem steckbare Schaltungsplatten zusammen mit den Haltebügeln leicht auswechselbar sind, was den Service im Reparaturfall dieser Geräte erleichtert, wobei die defekten Module als Empfängerbausteine im Ganzen gegen neue lediglich ausgetauscht werden. Die defekten Bausteine werden in das Herstellerwerk zur Reparatur eingeschickt, wonach sie für einen anderen Austausch bereitstehen. Auf diese Weise kreisen die Bausteine mehrmals und werden mit ihren Haltebügeln mehrfach an- und abgeschraubt. Die Haltebügel besitzen zwecks Befestigung abgewinkelte Blechstreifen, in welchen Bohrungen angebracht sind, in die Blechschrauben gedreht werden, wodurch der Haltebügel samt Schaltungsplatte des Bausteins mit der Grundschaltungsplatte im Nachrichtengerät me-Such retaining brackets are used, for example, in the modular design in communication devices, in that plug-in circuit boards are easily exchangeable together with the retaining brackets, which makes servicing these devices easier in the event of repairs, with the defective modules as receiver modules simply being exchanged for new ones as a whole. The defective modules are sent to the manufacturer for repair, after which they are available for another exchange. In this way, the blocks circle several times and are screwed on and unscrewed several times with their retaining brackets. The retaining brackets have angled sheet metal strips for the purpose of fastening, in which holes are made, into which the sheet metal screws are screwed, whereby the retaining bracket together with the circuit board of the module corresponds to the basic circuit board in the communication device.

chanisch fixiert wird. Diese Art der Befestigung hat den Nachteil, daß die Bohrungen bei oftmaligen Festziehen der Blechschrauben ausreißen können und kein sicherer Sitz für den Haltebügel mehr gewährleistet ist. Der Haltebügel wird dadurch unbrauchbar, nur weil die Befestigungslöcher für das Gewinde der Schrauben keinen festen Sitz mehr bieten, und müssen deshalb fortgeworfen werden. Der Neuerung liegt die Aufgabe zu Grunde, eine derartige Vorrichtung zur Befestigung oben beschriebener Haltebügel zu schaffen, die die geschilderten · Nachteile nicht besitzt, und die auch nach oftmaligem Gebrauch noch festen Sitz garantiert und im Fall eines Defektes leicht auswechselbar ist und den Haltebügel weiterhin benutzbar macht.is fixed chanically. This type of attachment has the disadvantage that the holes often Tightening the self-tapping screws can tear and no secure fit for the retaining bracket more is guaranteed. This makes the retaining bracket unusable just because the mounting holes no longer provide a tight fit for the thread of the screws and must therefore be thrown away. The innovation is based on the object of such a device for fastening the above-described To create retaining brackets that do not have the disadvantages described, and that even after repeated use Use still guarantees a tight fit and is easily replaceable in the event of a defect and the retaining bracket still usable.
Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß in entsprechende Ausnehmungen, die an den Enden des Haltebügels angebracht sind, aus elastischem Material, z.B. Kunststoff, bestehende Klemmteile federnd eingerastet sind, die in Richtung der abgewinkelten Schenkel des Haltebügels Löcher besitzen, in welche Schrauben eindrehbar sind, die den Haltebügel mit der Grundschaltungsplatte des Nachrichtengerätes verbinden.According to the innovation, this object is achieved in that in corresponding recesses at the ends of the retaining bracket are made of elastic material, e.g. plastic, existing clamping parts are resiliently latched, which have holes in the direction of the angled legs of the retaining bracket, in which screws can be screwed that the retaining bracket with the basic circuit board of the communication device associate.
Nachstehend wird die" Neuerung mit Hilfe der Figuren 1 bis 4 näher beschrieben.The "innovation" is described in more detail below with the aid of FIGS.

Figur 4 zeigt einen Schnitt längs der Linie IV-IV der Figur 3.FIG. 4 shows a section along the line IV-IV in FIG.
In Figur 1 stellt 1 die Grundschaltungsplatte des Nachrichtengerätes dar, auf die der Modulbaustein 2 aufgesteckt und befestigt ist. Die Schaltungsplatte des Modulbausteins 2 wird dabei in Führungsrippen 4 eines Haltebügels 5 fixiert. Die elektrische Verbindung der Schaltungsplatte 3 mit der Grundschaltungsplatte 1 erfolgt über Steckkontakte 6. Der Haltebügel 5 dient gleichzeitig als Kühlfläche für auf diesem angebrachte Leistungstransistoren 7. An den Enden der freien Schenkel des U-förmigen Haltebügels sind Ausnehmungen 8 angebracht, in die Klemmteile 9 federnd einrasten. Zur Verdeutlichung ist dies in Figur 2 vergrößert dargestellt.In FIG. 1, 1 represents the basic circuit board of the communication device on which the module component 2 is attached and fastened. The circuit board of the module component 2 is in this case in guide ribs 4 a retaining bracket 5 fixed. The electrical connection of the circuit board 3 to the basic circuit board 1 takes place via plug contacts 6. The retaining bracket 5 also serves as a cooling surface for on This attached power transistors 7. At the ends of the free legs of the U-shaped retaining bracket recesses 8 are provided, into which the clamping parts 9 snap resiliently. For clarification is this is shown enlarged in FIG.
Das Klemmteil 9, das z.B. aus elastischem Kunststoff besteht, besitzt seitliche Nuten 10, in die die seitlichen Kanten der Ausnehmung 8 eingreifen. Die seitlichen Kanten der Ausnehmung 8 besitzen Einkerbungen 11, die mit entsprechenden Erhebungen 12 in den Nuten 10 korrespondieren, wodurch das Klemmteil 9 federnd einrastet. Damit bei unterschiedlichen Blechstärken des Haltebügels 5 immer ein fester Sitz des Klemmteils 9 gewährleistet ist, ist eine Seitenwand 10' der Nute 10 federnd nach innen ausgebildet. Parallel zur abgewinkelten Seitenwand des Haltebü-The clamping part 9, which consists, for example, of elastic plastic, has lateral grooves 10 into which the lateral Engage the edges of the recess 8. The side edges of the recess 8 have notches 11, which correspond to corresponding elevations 12 in the grooves 10, whereby the clamping part 9 is resilient clicks into place. So that with different sheet metal thicknesses of the bracket 5 there is always a tight fit of the Clamping part 9 is guaranteed, a side wall 10 'of the groove 10 is resilient inward. Parallel to the angled side wall of the retaining bracket

gels 5 ist das Klemmteil 9 ein Loch 13 zur Aufnahme von Blechschrauben 14 vorgesehen, die durch Bohrungen 15 in der Grundschaltungsplatte 1 den Bügel 2 festhalten. Das Loch 13 ist vorteilhafterweise von dreieckformigem Querschnitt.gels 5, the clamping part 9 is provided with a hole 13 for receiving sheet metal screws 14, which are drilled through 15 hold the bracket 2 in the basic circuit board 1. The hole 13 is advantageously from triangular cross-section.
In Figur 3 ist das Klemmteil 9 in Draufsicht dargestellt, in welcher die Merkmale zur sicheren Befestigung zu erkennen sind, indem die Nuten 10 Erhebungen 12 besitzen und dieSeitenwand 10' der Nute 10 nach innen abgewinkelt ist.In Figure 3, the clamping part 9 is shown in plan view, in which the features for secure fastening can be recognized by the grooves 10 Have bumps 12 and the side wall 10 'of the groove 10 is angled inward.
