Description

Die Erfindung betrifft eine lösbare elektrisch leitende Verbindung von Kabeln, insbesondere von Flachkabeln, deren Enden auf einer Oberfläche Kontaktflächen aufweisen und in eine Verbindungsvorrichtung eingeschoben sind, die benachbart zu einer Kabeleinschuböffnung eine mittels eines Betätigungshebels in eine Wirklage drehbare Welle und ein an der Welle (15) angeordnetes Druckelement aufweist, das eine Druckkraft auf die Kontaktflächen der Kabel ausübt.The invention relates to a detachable, electrically conductive connection of cables, in particular flat cables, the ends of which have contact surfaces on one surface and are inserted into a connecting device which, adjacent to a cable insertion opening, has a shaft which can be rotated into an active position by means of an actuating lever and a shaft on the shaft (15 ) arranged pressure element which exerts a compressive force on the contact surfaces of the cables.

Lösbare Kabelverbindungen, insbesondere für flexible Leitungssteckverbindungen zwischen Schaltungeseinheiten, bestehen üblicherweise aus Kontaktstiften oder -federn, die in entsprechende gefederte Buchsen eingesteckt werden. Zur Aufrechterhaltung einer ausreichenden Federkraft für die Gewährleistung der Kontaktverbindung werden hierbei die Abmessungen der Federn in den Buchsen etwas geringer gehalten als die Kontaktstifte bzw. -federn dick sind. Diese bekannten Kontaktanordnungen haben den Nachteil, daß, wenn eine größere Zahl von Kontaktstiften gleichzeitig eingeschoben werden muß, ein erheblicher Kraftaufwand zum Einschieben der Kontakte erforderlich ist. Weiterhin können Probleme auftreten, wenn durch häufiges Einschieben und Herausziehen die Federelemente im Laufe der Zeit einem gewissen Verschleiß ausgesetzt sind.Detachable cable connections, in particular for flexible line plug connections between circuit units, usually consist of contact pins or springs which are inserted into corresponding spring-loaded sockets. In order to maintain a sufficient spring force to ensure the contact connection, the dimensions of the springs in the sockets are kept somewhat smaller than the contact pins or springs are thick. These known contact arrangements have the disadvantage that if a larger number of contact pins have to be inserted at the same time, considerable effort is required to insert the contacts. Problems can also arise if the spring elements are exposed to a certain amount of wear over time due to frequent insertion and removal.

Durch die US-A-4 054 348 ist ein Verbindungselement zwischen einem Flachkabel und einer Gedruckte-Schaltungs-Platte bekannt, das als Platte ausgebildet ist, durch die das Kabel mittels eines Schlitzes hindurchgeführt ist und die zur Herstellung des Kontaktes zwischen dem Flachkabel und der Schaltungsplatte auf die Gedruckte-Schaltungs-Platte geschwenkt und in der Schließstellung verriegelt wird. Hierbei wird die leitende Verbindung zwischen den Flachkabelsträngen und den leitenden Bereichen der Schaltungsplatte mittels einer Rippe bewirkt, die eine ständige Anpresskraft auf das auf der Schaltungsplatte aufliegende Kabel ausübt.From US-A-4 054 348 a connecting element between a flat cable and a printed circuit board is known, which is designed as a plate through which the cable is guided by means of a slot and which is used to establish the contact between the flat cable and the Circuit board is pivoted onto the printed circuit board and locked in the closed position. The conductive connection between the flat cable strands and the conductive areas of the circuit board is effected by means of a rib, which exerts a constant contact pressure on the cable resting on the circuit board.

Aus dem IBM Technical Disclosure Bulletin, Band 7, Nr. 9, Seite 742 ist weiterhin eine Flachkabelverbindungsvorrichtung bekannt, bei der ein mit einem Leitungsmuster lösbar zu verbindendes Flachkabel in eine Kabeleinschuböffnung eingeschoben wird, die von dem zur Verbindung vorgesehenen Leitungsmuster und einem spiralförmigen Federelement gebildet wird. Zur Herstellung der Kontaktverbindung wird ein Betätigungshebel geschwenkt, wodurch die Welle, auf der die spiralförmige Feder befestigt ist, gedreht wird und sich demzufolge ihre auf das Flachkabel wirksame Kraft erhöht. Diese Vorrichtung hat den Nachteil, daß das Kabel beim Einlegen in die Vorrichtung gegen eine gewisse, von der Feder ausgeübte anfängliche Widerstandskraft eingeschoben werden muß, bevor die eigentliche Kontaktverbindung durch Betätigen des Betätigungshebels hergestellt wird.A flat cable connecting device is also known from the IBM Technical Disclosure Bulletin, Volume 7, No. 9, page 742, in which a flat cable to be detachably connected to a line pattern is inserted into a cable insertion opening, which is formed by the line pattern provided for the connection and a spiral spring element becomes. To establish the contact connection, an actuating lever is pivoted, as a result of which the shaft on which the spiral spring is fastened is rotated and, consequently, its force acting on the flat cable increases. This device has the disadvantage that the cable must be inserted into the device against a certain initial resistance force exerted by the spring before the actual contact connection is made by actuating the actuating lever.

Der Erfindung liegt die Aufgabe zugrunde, eine lösbare elektrisch leitende Kabelverbindung, insbesondere für Flachkabel, der eingangs genannten Bauart zu schaffen, bei welcher das Einlegen des zur Herstellung der Verbindung zugeführten Kabelstranges widerstandsfrei möglich ist, auch wenn es sich um eine große Anzahl gleichzeitig herzustellender Kontaktverbindungen handelt. Diese Aufgabe ist bei einer Vorrichtung der oben beschriebenen Gattung durch die im Anspruch 1 genannte Ausführung gelöst worden.The invention has for its object to provide a releasable electrically conductive cable connection, in particular for flat cables of the type mentioned, in which the insertion of the cable harness supplied for establishing the connection is possible without resistance, even if it is a large number of contact connections to be made simultaneously acts. This object has been achieved in a device of the type described above by the embodiment mentioned in claim 1.

Die erfindungsgemäße Kabelverbindung eignet sich insbesondere auch für Wartungs- und Austauscharbeiten « im Feld », nämlich an einer am Einsatzort stehenden Maschine im Rahmen von Servicearbeiten, Fehlersuche und -beseitigung u. ä., bei denen Flachkabel Verwendung finden. Aber auch für Diagnosegeräte- und Meßgeräte-Anschlüsse und ähnliche Anwendungen ist die erfindungsgemäße Verbindung mit großem Vorteil einsetzbar.The cable connection according to the invention is also particularly suitable for maintenance and replacement work “in the field”, namely on a machine at the place of use as part of service work, troubleshooting and elimination u. Ä., where flat cables are used. However, the connection according to the invention can also be used with great advantage for diagnostic device and measuring device connections and similar applications.

Ein zusätzlicher Vorteil beim Einsatz der Anordnung nach der Erfindung ist dadurch gegeben, daß die miteinander zu verbindenden Kontaktflächen eine relative Schubbewegung ausführen, wenn durch die Hebelbewegung der Kontakt hergestellt wird ; dadurch wird eine besonders zuverlässige Kontaktverbindung gewährleistet.An additional advantage when using the arrangement according to the invention is given in that the contact surfaces to be connected to one another perform a relative pushing movement when the contact is made by the lever movement; this ensures a particularly reliable contact connection.

Die Erfindung wird im folgenden anhand der Zeichnungen in einem Ausführungsbeispiel erläutert.The invention is explained below with reference to the drawings in one embodiment.

Es zeigen :

  • Figur 1 eine schaubildliche Darstellung einer Verbindungseinrichtung zum Verbinden zweier Flachkabel vor dem Einschieben der Flachkabel, und
  • Figur 2 einen vergrößerten Schnitt durch die Einrichtung nach Fig. 1 nach dem Einschieben der Kabel und dem Betätigen der Vorrichtung.
Show it :
  • 1 shows a diagrammatic representation of a connecting device for connecting two flat cables before inserting the flat cables, and
  • Figure 2 is an enlarged section through the device of Fig. 1 after inserting the cable and operating the device.

Die in den Zeichnungen dargestellte Einrichtung besteht aus einem vorzugsweise aus Kunststoff hergestellten Gehäuse 10, welches im unteren Bereich eine Kammer 11 bildet, und in deren oberem Bereich sich eine Öffnung 12 befindet, die mit der Kammer 11 in Verbindung steht. Weiterhin befindet sich an der einen Seite des Gehäuses 10 eine Einschuböffnung 13 für ein unteres Flachkabel 19 und an der anderen Seite eine Einschuböffnung 14 für ein oberes Flachkabel 20, wobei beide Einschuböffnungen 13, 14 in die Kammer 11 führen.The device shown in the drawings consists of a housing 10, preferably made of plastic, which forms a chamber 11 in the lower region and in the upper region of which there is an opening 12 which is connected to the chamber 11. Furthermore, there is an insertion opening 13 for a lower flat cable 19 on one side of the housing 10 and an insertion opening 14 for an upper flat cable 20 on the other side, both insertion openings 13, 14 leading into the chamber 11.

Auf einer drehbaren Welle 15 im oberen Bereich des Gehäuses 10 ist eine Nockenwalze 16 exzentrisch gelagert und verläuft über die gesamte Länge der Öffnung 12. Die Nockenwalze 16 ist mit einem Mantel 17 aus synthetischem Gummi versehen, dessen Dicke im Bereich von 0,5 bis 1,5 mm gewählt ist, je nach Ausführung der zu verbindenden Kabel. Mittels eines mit der Welle 15 verbundenen Betätigungshebels 18 kann die exzentrische Nockenwalze 16 gedreht werden.A cam roller 16 is mounted eccentrically on a rotatable shaft 15 in the upper region of the housing 10 and extends over the entire length of the opening 12. The cam roller 16 is provided with a jacket 17 made of synthetic rubber, the thickness of which is in the range from 0.5 to 1 .5 mm is selected, depending on the design of the cables to be connected. The eccentric cam roller 16 can be rotated by means of an actuating lever 18 connected to the shaft 15.

Die oben beschriebene Einrichtung dient zur elektrischen Verbindung der beiden Flachkabel 19 und 20. Derartige Flachkabel werden in unterschiedlicher Dicke hergestellt und bestehen vorzugsweise aus einem polymeren Werkstoff, welcher kupferbeschichtet ist und anschließend geätzt wird, um Gedruckte-Schaltungs-Leiter 21 in einem bestimmten Muster zu erhalten. Diese sind mit einer Reihe Goldkontakte 22 verbunden, die auf der Oberfläche des Flachkabels nahe dem Ende aufgebracht sind. Die Goldkontakte 22 sind üblicherweise etwa 0,37 bis 0,5 mm breit und 0,75 bis 1,8 mm lang. Die Dicke der Flachkabel 19, 20 liegt üblicherweise im Bereich von 0,25 bis 0,35 mm, so daß sie infolge ihrer Elastizität zur Verbindung von gedruckten Schaltungskarten besonders geeignet sind, z. B. solchen gedruckten Schaltungskarten, die unterschiedliche Muster der Eingangs- und Ausgangskontakte haben. Sie werden aber auch dazu verwendet, planare gedruckte Schaltungskarten an die entsprechenden Kontakte im Computerrahmen anzuschließen, in den sie eingesetzt werden.The device described above is used for the electrical connection of the two flat cables 19 and 20. Such flat cables are produced in different thicknesses and preferably consist of a polymeric material which is copper-coated and subsequently etched in order to form printed circuit conductors 21 in a specific pattern receive. These are connected to a row of gold contacts 22 which are applied to the surface of the flat cable near the end. The gold contacts 22 are usually about 0.37 to 0.5 mm wide and 0.75 to 1.8 mm long. The thickness of the flat cable 19, 20 is usually in the range of 0.25 to 0.35 mm, so that due to their elasticity they are particularly suitable for connecting printed circuit boards, e.g. B. those printed circuit boards that have different patterns of the input and output contacts. They are also used to connect planar printed circuit boards to the corresponding contacts in the computer frame in which they are used.

In Fig. 2, welche zur Verdeutlichung die Teile nach Fig. 1 in etwa dreifacher Vergrößerung zeigt, ist die Ausgangslage des Betätigungshebels 18 gestrichelt dargestellt, in welcher sich die Nockenwalze 16 in ihrer « geöffneten oberen Lage befindet, wie gleichfalls gestrichelt gezeichnet.In Fig. 2, which shows the parts of FIG. 1 in approximately three times the magnification for clarity, the starting position of the actuating lever 18 is shown in dashed lines, in which the cam roller 16 is in its «open upper position, as also drawn in dashed lines.

Zum Verbinden der Flachkabel 19 und 20 wird zunächst das Flachkabel 19, mit den Goldkontakten 22 nach oben, in die Einschuböffnung 13 so weit wie möglich eingeschoben. Sodann schiebt man das Flachkabel 20 in die Einschuböffnung 14 an der entgegengesetzten Seite der Einrichtung ein, und zwar in einer Ausrichtung, daß die Goldkontakte 22 an der Unterseite liegen. Hierbei gleitet sie mit den Goldkontakten 22 auf den entsprechenden Kontakten auf der Oberfläche des Flachkabels 19. Auch das Flachkabel 20 wird so weit wie möglich in die Kammer 11 hineingeschoben, wobei es die in Fig. 2 mit 23 gekennzeichnete, gestrichelt dargestellte Position einnimmt. Die Goldkontakte 22 beider Flachkabel 19, 20 liegen nun aufeinandergedeckt. Nun wird der Betätigungshebel 18 im Uhrzeigersinn betätigt, so daß die Nockenwalze 16 einen wachsenden Druck auf die Oberseite des Flachkabels 20 ausübt und die paarweise einander gegenüberliegenden Goldkontakte 22 mehr und mehr aufeinandergepresst werden. Gleichzeitig führt infolge der Drehbewegung der Nockenwalze 16 das Flachkabel 20 eine Horizontalbewegung nach links aus, so daß zwischen den Goldkontaktpaaren 22 eine Schubbewegung erzeugt wird, welche sowohl einen Reinigungseffekt als auch eine besonders innige Berührung der Kontaktflächen zur Folge hat. Nach der Betätigung des Betätigungshebels 18 um einen Winkel von 180° stößt dieser an einer Anschlagfläche 24 des Gehäuses 10 an, und nun haben im Kontaktbereich 25 die Kontaktpaare ihre endgültige Lage zueinander erreicht. Je nach Bemessung der Nockenwalze 16 beträgt die Horizontalschubbewegung des Flachkabels 20 etwa 0,75 bis 1,25 mm.To connect the flat cables 19 and 20, the flat cable 19 is first inserted into the insertion opening 13 as far as possible, with the gold contacts 22 facing upwards. The flat cable 20 is then inserted into the insertion opening 14 on the opposite side of the device, in such a way that the gold contacts 22 lie on the underside. Here, it slides with the gold contacts 22 on the corresponding contacts on the surface of the flat cable 19. The flat cable 20 is also pushed as far as possible into the chamber 11, taking the position shown in FIG. 2 with a dashed line. The gold contacts 22 of both flat cables 19, 20 are now covered. Now the actuating lever 18 is actuated clockwise, so that the cam roller 16 exerts increasing pressure on the top of the flat cable 20 and the gold contacts 22, which are opposed in pairs, are pressed more and more against one another. At the same time, due to the rotary movement of the cam roller 16, the flat cable 20 performs a horizontal movement to the left, so that a pushing movement is generated between the gold contact pairs 22, which results in both a cleaning effect and a particularly intimate contact of the contact surfaces. After actuation of the actuation lever 18 by an angle of 180 °, it abuts a stop surface 24 of the housing 10, and now the contact pairs have reached their final position in relation to one another in the contact area 25. Depending on the dimensioning of the cam roller 16, the horizontal pushing movement of the flat cable 20 is approximately 0.75 to 1.25 mm.

Mit dem Erreichen der Endstellung des Betätigungshebels 18 an der Anschlagfläche 24 ist der höchste Bereich der Nockenwalze 16 bereits etwas überschritten, was durch das synthetische Material des Mantels 17 der Nockenwalze 16 unterstützt wird, so daß der Hebel 18 in seiner Endstellung festgehalten und auf die Kontakte der Flachkabel 19, 20 eine gleichbleibende Kraft ausgeübt wird. Die Größe dieser Kraft kann maßgeblich beeinflußt werden durch die Wahl des Materials und der Dicke des Mantels 17 der Nockenwalze 16.With the reaching of the end position of the actuating lever 18 on the stop surface 24, the highest area of the cam roller 16 is already slightly exceeded, which is supported by the synthetic material of the jacket 17 of the cam roller 16, so that the lever 18 is held in its end position and on the contacts the flat cable 19, 20 a constant force is exerted. The magnitude of this force can be significantly influenced by the choice of the material and the thickness of the jacket 17 of the cam roller 16.

Zum Lösen der Flachkabel 19, 20 wird der Betätigungshebel 18 entgegen dem Uhrzeigersinn um 180° in seine Ausgangslage zurückgeschwenkt, wodurch infolge des Abhebens der Nockenwalze 16 die beiden Flachkabel 19 und 20 freigegeben werden und herausgezogen werden können.To release the flat cable 19, 20, the actuating lever 18 is pivoted counterclockwise by 180 ° back into its starting position, as a result of which the two flat cables 19 and 20 are released and can be pulled out as a result of the cam roller 16 being lifted off.

Es ist zu bemerken, daß der Mantel 17 auf der Nockenwalze 16 gewisse Dickenunterschiede im Kontaktflächenbereich auszugleichen vermag und somit eine gleichmäßige Druckkraft gewährleistet. Weiterhin wird durch die Schubbewegung zwischen den Kontaktflächen im Verlauf der Schließbewegung des Betätigungshebels 18 der Kontaktübergang zwischen den beiden Flachkabeln 19, 20 außerordentlich günstig beeinflußt.It should be noted that the jacket 17 on the cam roller 16 is able to compensate for certain differences in thickness in the contact surface area and thus ensures a uniform pressure force. Furthermore, the contact transition between the two flat cables 19, 20 is influenced extremely favorably by the pushing movement between the contact surfaces in the course of the closing movement of the actuating lever 18.
