Die Erfindung bezieht sich auf eine Einrichtung zur Fixierung von Leiterplatten gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for fixing printed circuit boards according to the preamble of claim 1.
Bei der Fixierung von Leiterplatten in einem Gehäuse werden meist Schrauben verwendet. Dabei ergibt sich jedoch der Nachteil, daß bei einem Ausbau von Leiterplatten die Schrauben gelöst und nach dem Austausch der Leiterplatten wieder eingesetzt werden müssen, was mit einem beträchtlichen Montageaufwand verbunden ist.Screws are usually used to fix circuit boards in a housing. However, this has the disadvantage that when circuit boards are removed, the screws must be loosened and then reinserted after the circuit boards have been replaced, which involves considerable assembly work.
Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und eine Einrichtung der eingangs erwähnten Art vorzuschlagen, die einen Austausch von Leiterplatten ermöglicht.The aim of the invention is to avoid this disadvantage and to propose a device of the type mentioned at the outset which enables the exchange of printed circuit boards.
Erfindungsgemäß wird dies bei einer Einrichtung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved in a device of the type mentioned at the outset by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen ist es möglich, die Leiterplatten zwischen den Auflagen und den Vorsprüngen zu klemmen und dadurch zu fixieren. Bei einem Austausch von Leiterplatten können diese an dem von der Klemmeinrichtung abgekehrten Seite angehoben und aus dem Gehäuse entfernt werden.The proposed measures make it possible to clamp the circuit boards between the supports and the projections and thus fix them in place. When replacing circuit boards, they can be lifted on the side facing away from the clamping device and removed from the housing.
Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, daß der schwenkbare Hebel der Klemmeinrichtung auf einfache Weise unter Vorspannung gehalten werden kann.The features of claim 2 result in the advantage that the pivotable lever of the clamping device can be kept under pre-tension in a simple manner.
Dabei ergibt sich durch die Merkmale des Anspruches 3 eine in konstruktiver Hinsicht sehr einfache Lösung.The features of claim 3 result in a very simple solution in terms of construction.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:The invention will now be explained in more detail with reference to the drawing.
Fig. 1 einen Ausschnitt aus einer erfindungsgemäßen Einrichtung in axonometrischer Darstellung undFig. 1 shows a section of a device according to the invention in an axonometric view and
Fig. 2 einen Schnitt durch die Einrichtung nach der Fig. 1.Fig. 2 is a section through the device according to Fig. 1.
Gleiche Bezugszeichen bedeuten in beiden Figuren gleiche Einzelheiten.The same reference numerals indicate the same details in both figures.
In einem Gehäuse 1 sind nahe der Wände 2 vom Boden 3 aufragende Auflagen 3, 4 angeordnet, die zur Abstützung von Leiterplatten 5, 6 in verschiedenen Höhen dienen. Dabei sind die Leiterplatten 5, 6 mit randoffenen Schlitzen 7 versehen.In a housing 1, supports 3, 4 are arranged near the walls 2, protruding from the floor 3, which serve to support circuit boards 5, 6 at different heights. The circuit boards 5, 6 are provided with slots 7 with open edges.
Vom Boden 3 des Gehäuses 1 ragt ein Steher 8 auf, der über ein Filmschamier 9 mit einem
Hebel 10 einstückig verbunden und aus Kunststoff hergestellt ist. Dieser Hebel 10 ist mit
Vorsprüngen 11 versehen.A stand 8 protrudes from the bottom 3 of the housing 1 and is connected in one piece to a lever 10 via a film hinge 9 and is made of plastic. This lever 10 is provided with
projections 11.
Weiter ragt vom Boden 3 ein Widerlager 12 auf, das bis circa der halben Höhe des Stehers 8 reicht und an dem der Hebel 10 in dessen Sperrstellung anliegt und diesen vorspannt.Furthermore, an abutment 12 protrudes from the base 3, which reaches approximately half the height of the upright 8 and against which the lever 10 rests in its locked position and preloads it.
Bei der Montage der Leiterplatten 5, 6 wird der Hebel 10 nach unten geklappt und am Widerlager 12 zur Anlage gebracht. Danach wird die Leiterplatte 5 von der gegenüberliegenden Seite her eingeschoben, wobei die Leiterplatte 5 zwischen der Auflage 3 und der Unterseite des unteren Vorsprunges 11 eingeschoben wird. Dabei kommt es zu einer Klemmung der Leiterplatte 5.When assembling the circuit boards 5, 6, the lever 10 is folded down and brought into contact with the abutment 12. The circuit board 5 is then pushed in from the opposite side, whereby the circuit board 5 is pushed in between the support 3 and the underside of the lower projection 11. This causes the circuit board 5 to be clamped.
Die Montage der Leiterplatten 5 und 6 kann auch durch einfaches Einclipsen erfolgen. Anschließend wird in gleicher Weise die Leiterplatte 6 eingeschoben.The circuit boards 5 and 6 can also be mounted by simply clipping them in. The circuit board 6 is then inserted in the same way.
Bei einer Demontage der Leiterplatten 5, 6 werden diese in umgekehrter Reihenfolge durch Anheben an der vom Hebel 10 abgekehrten Seite des Gehäuses 1 aus dem Klemmspalt zwischen der Auflage 3 beziehungsweise 4 und den Vorsprüngen 11 des Hebels 10 gezogen. When dismantling the circuit boards 5, 6, they are pulled out of the clamping gap between the support 3 or 4 and the projections 11 of the lever 10 in the reverse order by lifting on the side of the housing 1 facing away from the lever 10.
Der Hebel 10 kann alternativ von Hand eingedrückt werden und entriegelt somit die Leiterplatte. Alternatively, the lever 10 can be pressed in by hand, thus unlocking the circuit board.
Das Gehäuse 1 ist mit einem Deckel 13 abgedeckt.The housing 1 is covered with a cover 13.
