Description
Bauteil zur Halterung von gedruckten Leiterplatten an einem Chassis In Geräten der Nachrichtentechnik, z. B. in Rundfunkempfängern, werden gedruckte Leiterplatten im allgemeinen mit Schrauben oder Bolzen an einem metallischen Chassis befestigt. Es ist aber im Zusammenhang mit einem Winkelschienenchassis auch bekannt (deutsche Auslegeschrift 1043 433), für zwei gegenüberliegende Seiten der Leiterplatte Leisten aus Kunststoff mit einer seitlichen Längsnut zu verwenden, in die die Leiterplatte eingeschoben wird. Die Leisten haben auch auf ihrer Unterseite eine Nut, die auf einen freien Schenkel einer Winkelschiene aufgeschoben wird. Da die Leiterplatte nicht in allen Richtungen gesichert ist, müssen noch weitere Mittel, z. B. Schrauben, zur Befestigung verwendet werden.Component for holding printed circuit boards on a chassis. In broadcast receivers, for example, printed circuit boards are generally attached to a metallic chassis with screws or bolts. In connection with an angle rail chassis, however, it is also known (German Auslegeschrift 1 043 433) to use strips made of plastic with a lateral longitudinal groove into which the circuit board is inserted for two opposite sides of the circuit board. The strips also have a groove on their underside, which is pushed onto a free leg of an angle rail. Since the circuit board is not secured in all directions, other means, such. B. screws, can be used for fastening.
Der Erfindung liegt die Aufgabe zugrunde, ein Bauteil zur Halterung von gedruckten Leiterplatten an einem Chassis zu schaffen, welches einfacher als die erwähnten Kunststoffstreifen ist und nicht auf eine passende Länge zurechtgeschnitten zu werden braucht.The invention is based on the object of a component for holding of printed circuit boards on a chassis, which is easier than the mentioned plastic strip is and is not cut to a suitable length needs to become.
Die Erfindung bezieht sich auf ein Bauteil zur Halterung von gedruckten Leiterplatten an einem Chassis, bei dem die Leiterplatte, wie oben beschrieben, in eine Nut im Bauteil eingeschoben ist. Erfindungsgemäß ist jede Leiterplatte durch vier an den Ecken angeordnete Bauteile aus Kunststoff mit einer in einem rechten Winkel verlaufenden Nut gehalten, und die Bauteile sind ihrerseits am Chassis befestigt. Das erfindungsgemäße Bauteil hat wie die obenerwähnten Kunststoffstreifen, jedoch im Gegensatz zu Schrauben oder Bolzen, den Vorteil, daß die ganze Leiterplatte auch an den Ecken für Leitungszüge ausnutzbar ist.The invention relates to a component for holding printed Printed circuit boards on a chassis, in which the printed circuit board, as described above, is inserted into a groove in the component. According to the invention, each circuit board is through four plastic components arranged at the corners with one in a right Angled groove held, and the components are in turn attached to the chassis. The component according to the invention has like the plastic strips mentioned above, however In contrast to screws or bolts, the advantage that the entire circuit board is also can be used at the corners for cable runs.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist zur Befestigung des Bauteils am Chassis am Bauteil das Oberteil eines Druckknopfes aus elastischem Kunststoff angeordnet, welches in ein Loch im Chassis einsteckbar ist.According to an advantageous development of the invention is for fastening of the component on the chassis on the component the upper part of a push button made of elastic Plastic arranged, which can be inserted into a hole in the chassis.
Die Zeichnung zeigt in F i g. 1 ein erfindungsgemäßes Bauteil, bei dem auch die erwähnte Weiterbildung der Erfindung angewendet ist; F i g. 2 stellt ein Anwendungsbeispiel des erfindungsgemäßen Bauteils dar.The drawing shows in FIG. 1 shows a component according to the invention in which the mentioned further development of the invention is also applied; F i g. 2 shows an application example of the component according to the invention.
Das Bauteil in F i g. 1 ist aus thermoplastischem Kunststoff, z. B. einem Polykarbonat mit dem Handelsnamen Makrolon, gespritzt. Es besteht aus zwei rechtwinklig zusammenstoßenden Wänden 1 und 2, die oben eine um die Ecke verlaufende Nut 3 bilden. Mit dem Boden 4 des Bauteils ist das Oberteil eines Druckknopfes 5 aus elastischem Kunststoff aus einem Stück gespritzt. Unten befindet sich das bimenförmige Teil, das elastisch federt und in ein Loch im Chassis einsteckbar ist. Zur Verbesserung der Federung ist das bimenförmige Teil mit einer wannenartigen Aushöhlung versehen.The component in FIG. 1 is made of thermoplastic material, e.g. B. a polycarbonate with the trade name Makrolon, injected. It consists of two walls 1 and 2 which meet at right angles and which form a groove 3 around the corner at the top. The upper part of a push button 5 made of elastic plastic is injection-molded in one piece with the base 4 of the component. At the bottom is the bimetallic part, which is elastic and can be inserted into a hole in the chassis. To improve the suspension, the bimetallic part is provided with a trough-like cavity.
In F i g. 2 sind zwei Leiterplatten 6 und 7 an zwei Winkelschienen 8 mit je vier Bauteilen an den Ecken befestigt. Für die große Leiterplatte 7 sind außerdem noch zwei Bauteile 10 vorgesehen, die wie die an den Ecken befindlichen Bauteile mit einer Nut versehen sind und zweckmäßig ebenfalls druckknopfartig in die Winkelschienen einsteckbar sind.In Fig. 2, two circuit boards 6 and 7 are attached to two angle rails 8 , each with four components at the corners. For the large printed circuit board 7 , two components 10 are also provided which, like the components located at the corners, are provided with a groove and can also be conveniently inserted into the angle rails in the manner of a push button.
Eine andere, weniger einfache Möglichkeit zur Befestigung der Bauteile am Chassis besteht darin, daß an die Bauteile Stifte angespritzt sind, die nach dem Einstecken in das Chassis durch Erhitzen mit einem Lötkolben breitgedrückt werden, so daß eine Art Nietverbindung entsteht.Another, less simple way of attaching the components on the chassis consists in that pins are molded onto the components that follow be pressed wide after inserting into the chassis by heating with a soldering iron, so that a kind of riveted connection is created.
