Description
Patentansprüche: 1. Anordnung zur Abstandshaltung für gedruckte Leiterplatten mittels Bolzen od. dgl., d a d u r c h gekennzeichnet, daß der Bolzen für jede Leiterplatte eine umlaufende Nut hat, deren Breite wie die Stärke der Leiterplatte bemessen ist, und daß der Boden der Nut an mindestens einer Stelle eine Abflachung aufweist, und daß weiter die Leiterplatte eine Bohrung enthält mit einem Durchmesser, der dem durch die Nut verringerten Durchmesser des Bolzens entspricht, und daß die Bohrung durch einen Schlitz mit einer Breite entsprechend dem durch die Abflachung zusätzlich verringerten Bolzendurchmesser zum Rand des plattenförmigen Bauteils hin geöffnet ist, so daß der Bolzen in wenigstens einer Stellung vom Rand her in die Bohrung einsetzbar und durch eine axiale Verdrehung verriegelbar ist. Claims: 1. Arrangement for keeping a spacing for printed circuit boards by means of bolts or the like, d a d u r c h characterized that the bolt for each circuit board has a circumferential groove, the width of which is measured as the thickness of the circuit board, and that the bottom of the groove has a flattening at at least one point, and that further the circuit board contains a bore with a diameter that the corresponds to the reduced diameter of the bolt through the groove, and that the bore by a slot with a width corresponding to that by the flattening in addition reduced bolt diameter open towards the edge of the plate-shaped component is, so that the bolt in at least one position from the edge into the bore can be used and locked by an axial rotation.
2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß der Boden der Nut an zwei gegenüberliegenden Stellen in gleichem Maße abgeflacht ist und daß der Schlitz in der Leiterplatte symmetrisch zur Mittellinie der Bohrung liegt. 2. Arrangement according to claim 1, characterized in that the bottom the groove is flattened to the same extent at two opposite points and that the slot in the circuit board is symmetrical to the center line of the hole.
3. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß der Bolzen eine Nase trägt, an der die Lage der Abflachung erkennbar ist. 3. Arrangement according to claim 1, characterized in that the bolt has a nose that shows the location of the flat.
Leiterplatten werden vielfach auf Abstandshaltern auf dem Chassis befestigt. Auch werden Abstandshalter bei der Verbindung mehrerer Leiterplatten übereinander verwendet. Eine bekannte Ausführungsform ist z. B. Circuit boards are often placed on spacers on the chassis attached. Spacers are also used when connecting multiple circuit boards used on top of each other. A known embodiment is e.g. B.
ein Bolzen, dessen eine Seite als Schraubgewinde ausgeführt ist und dessen andere Seite eine Bohrung mit Innengewinde zur Aufnahme des Schraubgewindes eines weiteren Bolzens oder einer Schraube enthält. Es lassen sich mit Hilfe dieser Abstandshalter Leiterplatten etagenweise übereinander aufbauen. Sie haben folgende Nachteile: Wenn man eine zwischen weiteren Leiterplatten montierte Leiterplatte herausnehmen möchte, so müssen alle später montierten der Reihe nach gelöst und entfernt werden.a bolt, one side of which is designed as a screw thread and the other side has a hole with an internal thread to accommodate the screw thread another bolt or screw. It can be done with the help of this Build up the spacers on the printed circuit boards one on top of the other. You have the following Disadvantages: If you have a printed circuit board mounted between other printed circuit boards want to take out, then all later installed must be solved and in sequence removed.
Weiter sind rohrförmige Abstandshalter bekannt (DT-Gbm 18 78 057), die mit ihren Enden in die Leiterplatten haltend eingreifen und in der Art einer Bajonettverbindung mit ihr verrenkt werden. Der Abstandshalter hat zu diesem Zweck L-förmige Schlitze, in die Teile der Leiterplatte hineinragen. Tubular spacers are also known (DT-Gbm 18 78 057), which engage with their ends in the circuit boards holding and in the manner of a Bayonet connection to be dislocated with her. The spacer did this for this purpose L-shaped slots into which parts of the circuit board protrude.
Beide bekannten Abstandshalter haben den Nachteil, daß durch einen Abstandshalter nur jeweils zwei Leiterplatten miteinander verbunden werden können. Both known spacers have the disadvantage that by one Spacers only two at a time Printed circuit boards can be connected to each other.
so daß die Montage und Demontage umständlich und zeitraubend ist.so that the assembly and disassembly is cumbersome and time consuming.
Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zur Abstandshaltung für Leiterplatten zu schaffen, die sich für eine lösbare Verbindung mit einer oder beliebig vieler Leiterplatten miteinander eignet. The invention is based on the object of an arrangement for maintaining spacing for creating printed circuit boards that are suitable for a releasable connection with an or any number of printed circuit boards with each other is suitable.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. This object is achieved by the invention specified in claim 1.
