Description

Die Erfindung bezieht sich auf eine Vorrichtung zum gegenseitigen elektrischen Kontaktieren von elektrischen und/oder elektromechanischen Baugruppen in einem Gehäusen eines elektrischen Gerätes, wie Autoradio, Video- oder Audio-Recorder sowie Daten-Endgerät, wie Drucker, vorzugsweise an schwer zugänglichen Kontaktierungsstellen zwischen diesen Baugruppen, mit je einem Steckelement an einer ersten Baugruppe und an einer zweiten Baugruppe, wobei das Steckelement der ersten Baugruppe über flexible elektrische Leitungen mit Komponenten der ersten Baugruppe verbunden ist, sowie ein Verfahren zum Kontaktieren von Baugruppen mittels dieser Vorrichtung und ein Gerät, das nach dem Verfahren gefertigt ist.The invention relates to a device for the mutual electrical contacting of electrical and / or electromechanical assemblies in a housing of an electrical device, such as a car radio, video or audio recorder and data terminal device, such as a printer, preferably at difficult to access contact points between these assemblies , each with a plug-in element on a first assembly and on a second assembly, the plug-in element of the first assembly being connected to components of the first assembly via flexible electrical lines, as well as a method for contacting assemblies by means of this device and a device according to the Process is made.

Eine derartige Vorrichtung ist bei Autoradiokassetten-spieler bekannt. Bei schwer zugänglichen Kontaktierungsstellen innerhalb des Gehäuses eines elektrischen Gerätes ergibt sich aber die Schwierigkeit, daß das Kontaktieren an den schwer zugänglichen Stellen zeit- und arbeitsaufwendig ist. Besonders schwierig wird das Kontaktieren dann, wenn bei nachträglichen Reparaturen die Kontaktstellen an den schwer zugänglichen Stellen gelöst und wieder neu verbunden werden müssen. Dies gilt insbesondere bei Geräten, bei denen in sehr kompakter Weise gearbeitet wird, wie beispielsweise bei den genannten Autoradiokassetten-spielern. Bei einer zunehmenden automatischen Fertigung dieser Geräte fällt die elektrische Kontaktierung an den unzugänglichen Stellen relativ stark kostensteigernd ins Gewicht.Such a device is known in car radio cassette players. In the case of contact points which are difficult to access within the housing of an electrical device, however, there is the difficulty that contacting the difficult-to-reach places is time-consuming and labor-intensive. Contact is particularly difficult when in the event of subsequent repairs, the contact points in the hard-to-reach places have to be loosened and reconnected. This applies in particular to devices in which work is carried out in a very compact manner, for example in the case of the above-mentioned car radio cassette players. With an increasing automatic production of these devices, the electrical contacting in the inaccessible places has a relatively strong cost-increasing effect.

Es ist Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren zu schaffen, mit deren Hilfe es möglich ist, die elektrische Kontaktierung von Baugruppen innerhalb des Gehäuses eines Gerätes mit engen Plazierungsräumen zu vereinfachen sowie die nachträgliche Reparatur zu erleichtern.It is an object of the invention to provide a device and a method with the aid of which it is possible to simplify the electrical contacting of assemblies within the housing of a device with narrow placement spaces and to facilitate subsequent repair.

Die gestellte Aufgabe ist erfindungsgemäß dadurch gelöst, daß das Steckelement der ersten Baugruppe an einer sich bis in einen leicht zugänglichen Bereich des Gehäuses erstreckenden Halterung angeordnet ist und daß diese Halterung lösbar an einem Träger der ersten Baugruppe festklemmbar ist, derart daß dieses Steckelement bei einem Abdrücken und Freikommen der Halterung vom Träger in das Steckelement der zweiten Baugruppe einführbar ist.The object is achieved in that the plug element of the first assembly is arranged on a bracket extending into an easily accessible area of the housing and that this bracket is releasably clamped to a carrier of the first assembly, so that this plug element when pressed and the holder can be inserted into the plug-in element of the second assembly.

Auf diese Weise ist es möglich, daß bei der Montage der Baugruppe innerhalb eines Gehäuses die Kontaktierung an sehr unzugänglichen Stellen ohne besonderes Fingerspitzengefühl möglich ist. Hinzu kommt noch, daß die Kontaktierung auch möglich ist mit Hilfe von maschinellen Einrichtungen, wie Robotern, die die Halterungen einfach an den Plazierungsstellen niederdrücken, wobei der Roboter ohne besonderes Führungsvermögen allein durch das Niederdrücken die gegenseitige Kontaktierung der ersten und zweiten Baugruppe herbeiführt, weil die Steckelemente der ersten Baugruppe von den Steckelementen der zweiten Baugruppe gefangen werden. Durch das Freikommen der Halterungen vor dem Einfangen können gegenseitige Toleranzen der Baugruppen innerhalb des Gehäuses ohne Schwierigkeiten ausgeglichen werden.In this way, it is possible that when assembling the module within a housing, contacting is possible in very inaccessible places without particular sensitivity. Add to that the contacting It is also possible with the help of mechanical devices, such as robots, which simply press the holders down at the placement points, the robot, without any special guidance, bringing the first and second assemblies into contact with one another simply by pressing down, because the plug-in elements of the first sub-assembly are separated from the plug-in elements the second assembly. By freeing the brackets before capturing, mutual tolerances of the assemblies within the housing can be compensated for without difficulty.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß der Träger mit Führungen versehen ist, die in Abdrückrichtung verlaufen, und daß die Halterung Nuten aufweist, die beim Aufschieben der Halterung auf den Träger über die Führungen fahren. Es ist an sich aus der DE-OS 33 01 568 bekannt, zwei Baugruppen mit Steckerteilen zu verbinden, wobei Führungen ein genaues zusammentreffen der Steckerteile gewährleisten. Die Führungen können dabei an einem Rahmen angeordnet sein.According to a further embodiment of the invention, it is provided that the carrier is provided with guides which run in the push-off direction, and that the holder has grooves which run over the guides when the holder is pushed onto the carrier. It is known per se from DE-OS 33 01 568 to connect two assemblies with plug parts, with guides ensuring an exact meeting of the plug parts. The guides can be arranged on a frame.

Bei einer anderen Ausgestaltung ist vorgesehen, daß die Halterung mit Führungen versehen ist, die in Abdrückrichtung verlaufen, daß der Träger Nuten aufweist und daß die Halterung mit ihren Führungen beim Aufschieben auf den Träger in die Nuten einfährt. Bei der Vormontage lassen sich auf diese Art und Weise die Halterungen in die vorgegebenen Stellungen bringen, und bei nachträglichen Reparaturen lassen sich die Halterungen aus den Kontaktierungen wieder in die vorgegebenen Ausgangsstellungen herausziehen. Dabei arbeiten die Nuten und die Führungen immer auf geeignete Weise zusammen.In another embodiment it is provided that the holder is provided with guides which run in the push-off direction, that the carrier has grooves and that the holder with its guides moves into the grooves when pushed onto the carrier. During the pre-assembly, the brackets can be brought into the specified positions in this way, and during subsequent repairs, the brackets can be pulled out of the contacts into the specified starting positions. The grooves and the guides always work together in a suitable manner.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die auf den Träger aufgeschobene Halterung am Träger lösbar verklemmt bzw. verrastet ist. Bei der Vormontage sorgen die Verklemmungen bzw. die Verrastungen dafür, daß die Halterungen immer sicher in den vorgegebenen Ausgangspositionen für das Niederdrücken festgehalten werden. Auch bei späteren Reparaturen ist dies ein Vorteil, weil die hochgezogenen Halterungen nicht lose liegen, sondern festgehalten sind.According to a further embodiment of the invention it is provided that the holder pushed onto the carrier is releasably clamped or latched to the carrier. During the pre-assembly, the clamps or the catches ensure that the brackets are always held securely in the specified starting positions for depressing. This is also an advantage for later repairs because the raised brackets are not loose, but are held in place.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Führungen und die Nuten in Abdrückrichtung über eine derartige Länge zusammenarbeiten, daß die Halterung kurz nach dem Beginn des Abdrückens von dem Träger freikommt. Unmittelbar nach dem Abdrücken ist die Halterung damit so freigegeben, daß sie genügendes Spiel hat, um sich ausrichten zu können zu dem Steckelement der zweiten Baugruppe.According to a further embodiment of the invention, it is provided that the guides and the grooves work together in the push-off direction over such a length that the holder is released from the carrier shortly after the push-off begins. Immediately after pressing the holder is released so that it has enough play to align with the plug element of the second assembly.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß ein Teil der Halterung gleichzeitig als Griff für ein Werkzeug und für eine manuelle Handhabung ausgebildet ist. Eine solche Griffausbildung ist besonders für Reparaturzwecke reparaturfreundlich, erleichtert aber auch den Einsatz von Robotern.According to a further embodiment of the invention, it is provided that part of the holder is simultaneously designed as a handle for a tool and for manual handling. Such a handle design is particularly easy to repair for repair purposes, but also makes the use of robots easier.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß das Gehäuse dieses Steckelementes einer der Baugruppen einen Einführtrichter für das Steckelement der anderen Baugruppe aufweist. Dieser Einführtrichter sorgt für ein sicheres Einfangen des Steckelementes der ersten Baugruppe in dem Steckelement der zweiten Baugruppe. Damit lassen sich gegenseitige Toleranzen zwischen den Baugruppen im Gehäuse noch besser und leichter ausgleichen.According to a further embodiment of the invention, it is provided that the housing of this plug-in element of one of the modules has an insertion funnel for the plug-in element of the other module. This insertion funnel ensures for securely catching the plug element of the first assembly in the plug element of the second assembly. This makes it easier and easier to compensate for mutual tolerances between the modules in the housing.

Es ist üblich und auch von Vorteil, wenn die einzelnen Baugruppen vor dem Zusammenfügen mit anderen Baugruppen zunächst einzeln auf ihre Funktionsfähigkeit überprüft werden. Dieses Überprüfen erfolgt mit Prüfvorrichtungen, die mit entsprechenden Kontakten für die Prüfung versehen sind. Nach einer bevorzugten Ausführungsform der Erfindung ist für diesen Zweck vorgesehen, daß sich das Steckelement der ersten Baugruppe bei verklemmter bzw. verrasteter Halterung in einer Stellung befindet, in der es beim Aufsetzen der ersten Baugruppe auf eine Prüfvorrichtung mit Kontakten der Prüfvorrichtung kontaktiert. Sind die Kontakte der Prüfvorrichtung so angeordnet, daß sie beim Aufsetzen der ersten Baugruppe auf die Prüfvorrichtung mit den in den Trägern verklemmten bzw. verrasteten Halterungen kontaktieren können, dann läßt sich die Prüfung schnell durchführen, und es brauchen die Steckelemente der ersten Baugruppe nicht durch besondere Hantierungen mit den Steckkontakten der Prüfvorrichtung verbunden werden. Durch einfaches Aufsetzen erfolgt eine sichere Kontaktierung.It is common and also advantageous if the individual assemblies are first checked individually for their functionality before being joined together with other assemblies. This checking is carried out with test devices which are provided with appropriate contacts for the test. According to a preferred embodiment of the invention, it is provided for this purpose that the plug-in element of the first assembly is in a position in the clamped or latched holder in which it contacts the test device with contacts when the first assembly is placed on a test device. If the contacts of the test device are arranged in such a way that when the first assembly is placed on the test device with the brackets clamped or locked in the carriers, the test can be carried out quickly, and the plug-in elements of the first assembly need not be special Handling is connected to the plug contacts of the test device. A simple contact ensures that contacting is secure.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Halterung eine Zugentlastungskante für die flexiblen Leitungen aufweist. Die flexiblen Kabelverbindungen, die vorzugsweise als Bandkabel ausgebildet sind, werden damit an der Halterung so festgelegt, daß sie beim Abdrücken nicht beschädigt werden können.According to a further embodiment of the invention, it is provided that the holder has a strain relief edge for the flexible lines. The flexible cable connections, which are preferably in the form of ribbon cables, are thus fixed to the holder in such a way that they cannot be damaged when they are pulled off.

Zur Durchführung des Kontaktierens mit Hilfe der Vorrichtung nach der Erfindung dient ein Verfahren, das dadurch gekennzeichnet ist, daß die erste Baugruppe in einer vorgesehenen Stellung zu der zweiten Baugruppe positioniert wird, daß die Halterung, deren Steckelement dabei in eine osition oberhalb der Steckelemente der Steckelemente der zweiten Baugruppe gelangt ist, in Richtung auf das Steckelement der zweiten Baugruppe vom Träger abgedrückt wird, daß die Halterung mit dem Steckelement beim Abdrücken vom Träger freikommt und daß das Steckelement der ersten Baugruppe auf seinem freien Bewegungsweg eingefangen und in das Steckelement der zweiten Baugruppe eingeleitet wird. Ein derartiges Verfahren eignet sich besonders für eine Massenfertigung und ist außerordentlich wirtschaftlich.To carry out the contacting with the aid of the device according to the invention, a method is used, which is characterized in that the first assembly is positioned in an intended position relative to the second assembly, that the holder, the plug element in an osition above the plug elements of the plug elements the second assembly has reached, is pushed in the direction of the plug-in element of the second assembly by the carrier, that the holder with the plug-in element is released from the carrier when the impression is taken, and that the plug-in element of the first assembly is caught on its free path of movement and introduced into the plug-in element of the second assembly becomes. Such a method is particularly suitable for mass production and is extremely economical.

Ein nach diesem Verfahren gefertigtes Gerät weist die Besonderheit auf, daß für die Bildung einer Öffnung im Gehäuse eine Wand des Gehäuses wenigstens teilweise weggelassen ist, wobei der Träger der ersten Baugruppe den Griff an der Halterung zur Öffnung und zu den anderen Baugruppen so plaziert, daß der Griff durch die Öffnung von außen zugänglich und handhabbar ist. Obwohl die Steckkontaktierungen zwischen den Baugruppen an unzugänglicher Stelle am Boden von schachtartigen Vertiefungen liegen, können die Kontaktierungen ohne Schwierigkeiten vorgenommen und wieder gelöst werden. Damit können die Baugruppen eng aufeinander zu gebaut werden, ohne daß diese Kontaktierungen zu Montageproblemen führen.A device manufactured according to this method has the special feature that for the formation of an opening in the housing a wall of the housing is at least partially omitted, the carrier of the first assembly placing the handle on the holder for opening and the other assemblies in such a way that the handle is accessible and manageable from the outside through the opening. Although the plug-in contacts between the modules are in an inaccessible place on the bottom of shaft-like depressions, the contacts can be made and released again without difficulty. This allows the modules to be built close to one another without these contacts leading to assembly problems.

Ein elektrisches Gerät nach der Erfindung, welches ein Autoradio, ein Video- oder Audio-Recorder sowie ein Daten-Endgerät, aber auch ein anderes Gerät sein kann, ist in Fig. 1 am Beispiel eines Autoradios dargestellt. Es kommt dabei darauf an, daß eine elektrische oder elektromechanische Baugruppe mit einer anderen oder mit anderen elektrischen oder elektromechanischen Baugruppen kontaktiert werden soll, wobei die Kontaktierungsstellen an schwer zugänglichen Bereichen innerhalb des Gerätes liegen.An electrical device according to the invention, which can be a car radio, a video or audio recorder and a data terminal, but also another device, is shown in FIG. 1 using the example of a car radio. It is important that an electrical or electromechanical assembly is to be contacted with another or with other electrical or electromechanical assemblies, the contact points being located in areas of the device which are difficult to access.

Bei dem Autoradio nach Fig. 1 handelt es sich um einige Baugruppen, die innerhalb eines Gehäuses 1 angeordnet sind. Das Gehäuse 1 weist eine Kastenform auf, und das Innere des Gehäuses ist für die Montage der Baugruppen durch Weglassen des Oberdeckels von oben her durch eine Öffnung 1a zugänglich. Eine erste Baugruppe 2 ist befestigt auf dem Boden des Gehäuses und ist das Laufwerk eines Kassettenspielers. Dieses Laufwerk, das in der DE-OS 33 12 136 (PHD 83-037) beschrieben ist, weist ein Chassis 3 auf, gegenüber dem drei Tastenstangen 4, 5, 6 verschieblich sind. Die Tastenstangen 4, 5, 6 greifen durch die Frontplatte 7 des Gehäuses 1 hindurch und sind von außen mittels Drucktasten 4a, 5a, 6a bedienbar. Das Laufwerk weist weiterhin einen Motor 8 zum Antrieb von Wickeldornen 9 auf und hat einen Magnetkopf 10, mit dem ein in einer Compact-Kassette 11 angeordnetes, nicht dargestelltes Magnetband abgetastet werden kann. Zum Transport des nicht dargestellten Magnetbandes dient eine Tonwelle 12, an die eine Andruckrolle 13 andrückbar ist. Der Motor 8 treibt auch die Tonwelle 12 an. Die Compact-Kassette 11 ist in einen Lift 14 einschiebbar und mit Hilfe des Liftes auf die Wickeldorne 9 absenkbar. Der Lift 14 wird gesteuert mit Hilfe eines Lifthebels 15, der aus Fig. 2 zu ersehen ist. Der Lifthebel 15 wird gesteuert mittels eines Auslegers 16, der von der Tastenstange 4 betätigt wird.1 is a few modules which are arranged within a housing 1. The housing 1 has a box shape, and the interior of the housing is accessible from above through an opening 1a for the assembly of the modules by omitting the top cover. A first assembly 2 is attached to the bottom of the housing and is the drive of a cassette player. This drive, which is described in DE-OS 33 12 136 (PHD 83-037), has a chassis 3, against which three key rods 4, 5, 6 are displaceable. The key bars 4, 5, 6 reach through the front plate 7 of the housing 1 and can be operated from the outside by means of push buttons 4a, 5a, 6a. The drive also has a motor 8 for driving winding mandrels 9 and has a magnetic head 10 with which a magnetic tape (not shown) arranged in a compact cassette 11 can be scanned. A magnetic shaft 12, to which a pressure roller 13 can be pressed, is used to transport the magnetic tape (not shown). The motor 8 also drives the audio shaft 12. The compact cassette 11 can be inserted into an elevator 14 and lowered onto the winding mandrels 9 with the aid of the elevator. The lift 14 is controlled with the aid of a lift lever 15, which can be seen in FIG. 2. The lift lever 15 is controlled by means of a boom 16 which is actuated by the push rod 4.

Wie bereits erwähnt, sind innerhalb des Gehäuses 1 mehrere andere Baugruppen, wie eine zweite Baugruppe 17, eine dritte Baugruppe 18, eine vierte Baugruppe 19, eine fünfte Baugruppe 20, ein Schalter 21 und Anschlußteile 22 vorgesehen. Zwischen den einzelnen Bauteilen erstrecken sich Kabelverbindungen, wie beispielsweise eine Kabelverbindung 23 und eine Kabelverbindung 24. Zwischen der ersten Baugruppe 2 und den anderen Baugruppen bilden sich Schächte 25 und 26 aus. Am Boden dieser Schächte an der zweiten Baugruppe 17 sollen elektrische Kontaktverbindungen mit der ersten Baugruppe 2 hergestellt werden. Die erste Baugruppe ist mechanisch fest mit dem Boden des Gehäuses 1 verbunden. Dabei treten Toleranzen auf, die es unmöglich machen, die mit der zweiten Baugruppe 17 verbundenen Kontakte unmittelbar fest mit dem Chassis 3 verbundene Kontakte der ersten Baugruppe 2 zu verbinden. Diese Toleranzen treten auf, weil beide Baugruppen unabhängig voneinander mit dem Gehäuse 1 verbunden sind und die Baugruppen selbst unabhängig voneinander Toleranzen aufweisen. Diese Toleranzen können sich summieren und dabei eine Größenordnung annehmen, daß die unmittelbare elektrische Kontaktierung fest an den Baugruppen angeordneter Kontakte für eine Massenfertigung nicht möglich ist.As already mentioned, several other modules, such as a second module 17, a third module 18, a fourth module 19, a fifth module 20, a switch 21 and connecting parts 22 are provided within the housing 1. Cable connections, such as a cable connection 23 and a cable connection 24, extend between the individual components. Shafts 25 and 26 are formed between the first module 2 and the other modules. At the bottom of these shafts on the second assembly 17, electrical contact connections are to be made with the first assembly 2. The first assembly is mechanically fixed to the bottom of the housing 1. In this case, tolerances occur which make it impossible to connect the contacts of the first assembly 2 which are connected directly to the chassis 3 to the chassis 3. These tolerances occur because the two assemblies are connected to the housing 1 independently of one another and the assemblies themselves have tolerances independently of one another. These tolerances can add up and assume an order of magnitude such that the direct electrical contacting of contacts fixedly arranged on the assemblies is not possible for mass production.

Um diese Toleranzen zu überspielen, ist das Gerät mit speziellen Vorrichtungen zum gegenseitigen elektrischen Kontaktieren versehen. Diese Vorrichtungen sind in Fig. 1 mit 27 für eine erste Vorrichtung und 28 für eine zweite Vorrichtung bezeichnet. Die erste Vorrichtung ist in Fig. 2 vergrößert herausgestellt, und die zweite Vorrichtung 28 ist in Fig. 3 vergrößert herausgestellt, wobei die elektrischen Kontaktierungen noch nicht vorgenommen sind.To cover these tolerances, the device is equipped with special devices for mutual electrical contact. These devices are designated in FIG. 1 by 27 for a first device and 28 for a second device. The first device is shown enlarged in FIG. 2 and the second device 28 is shown enlarged in FIG. 3, the electrical contacts not yet being made.

Die Vorrichtung 27 weist einen Träger 29 auf, der mit dem Chassis 3 fest verbunden ist. Der Träger 29 kann auch aus dem Blech des Chassis herausgearbeitet sein. Der Träger 29 liegt in der Nähe des Motors 8 und verläuft senkrecht zu der zweiten Baugruppe 17. Diese zweite Baugruppe ist eine stark bestückte elektrische Schaltungsplatte. Der Träger 29 hat Führungen 30, die zwei gegenüberliegende Ränder eines Loches 31 in der Mitte des Trägers 29 begrenzen. Die Führungen 30 verlaufen im wesentlichen senkrecht zu der zweiten Baugruppe 17. Der Träger 29 weist zwei Rastnasen 32 auf, die anschließend an die Führungen 30 gegeneinander in das Innere des Loches 31 weisen.The device 27 has a carrier 29 which is fixedly connected to the chassis 3. The carrier 29 can also be machined out of the sheet metal of the chassis. The carrier 29 is located in the vicinity of the motor 8 and extends perpendicular to the second assembly 17. This second assembly is a heavily populated electrical circuit board. The carrier 29 has guides 30 which delimit two opposite edges of a hole 31 in the center of the carrier 29. The guides 30 run essentially perpendicular to the second assembly 17. The carrier 29 has two latching lugs 32 which, after the guides 30, point towards one another into the interior of the hole 31.

In den Trägern 29 ist eine Halterung 33 vom Chassis 3 von der zweiten Baugruppe 17 her aufschiebbar. Die Halterung 33 ist vorzugsweise ein Kunststoffteil und weist zwei U-förmige Nuten 34 auf, die sich etwa parallel zu den Führungen 30 erstrecken. Die Nuten 34 sind mit Mulden 35 versehen, in die die Rastnasen 32 eingreifen, wenn die Halterung 33, wie in Fig. 2 dargestellt, voll eingeschoben ist. Ist die Halterung 33, wie in Fig. 2 dargestellt, voll eingeschoben, dann verklemmen sich am Nutgrund vorgesehene vorspringende Klemmränder 36 an den Führungen 30. Damit ist die Halterung 33 im voll eingeschobenen Zustand nach Fig. 2 an dem Träger 29 eindeutig positioniert und festgehalten.In the supports 29, a holder 33 can be pushed onto the chassis 3 by the second assembly 17. The holder 33 is preferably a plastic part and has two U-shaped grooves 34 which extend approximately parallel to the guides 30. The grooves 34 are provided with troughs 35, into which the locking lugs 32 engage when the holder 33, as shown in FIG. 2, is fully inserted. If the holder 33, as shown in FIG. 2, is fully pushed in, then projecting clamping edges 36 provided on the base of the groove become jammed on the guides 30. Thus, the holder 33 in the fully inserted state according to FIG. 2 is clearly positioned and held on the carrier 29 .

Die Halterung 33 ist bei der Darstellung Fig. 2 an ihrem oberen Randbereich mit einem Griff 37 versehen, der nach dem späteren Einsetzen von Hand oder von einem Gerät durch die Öffnung 1a erfaßbar ist. Innerhalb der Halterung 33 ist eine Zugentlastungskante 38 vorgesehen, über die ein Bandkabel 39 gezogen ist. Zwischen der Zugentlastungskante 38 und dem Griff 37 ist ein Durchzugsloch 40 vorgesehen, durch das das Bandkabel 39 hindurchgeschlauft ist. Das Bandkabel ist an ein Steckelement 41 herangeführt, das mit Steckerstiften 41a versehen ist. Das Steckelement 41 ist mit der Halterung 33 über eine Klammerverbindung 42 verbunden.In the illustration in FIG. 2, the holder 33 is provided with a handle 37 on its upper edge region, which can be inserted by hand or by a device after later insertion the opening 1a is detectable. A strain relief edge 38 is provided within the holder 33, over which a ribbon cable 39 is pulled. A pull-through hole 40 is provided between the strain relief edge 38 and the handle 37, through which the ribbon cable 39 is looped. The ribbon cable is brought up to a plug element 41, which is provided with plug pins 41a. The plug element 41 is connected to the holder 33 via a clamp connection 42.

An der zweiten Baugruppe 17 ist ein Einführtrichter 43 vorgesehen, der sich mit Hilfe von Klammernasen 44 an der zweiten Baugruppe 17 verklammert. Dieser Einführtrichter umfaßt ein anderes Steckelement 45, in dem Steckerbuchsen 45a vorgesehen sind. Die Steckerbuchsen sind über Anschlußdrähte 45b mit nicht dargestellten Leitungszügen der zweiten Baugruppe 17 verbunden.An insertion funnel 43 is provided on the second assembly 17 and clamps onto the second assembly 17 with the aid of clip lugs 44. This insertion funnel comprises another plug element 45, in which plug sockets 45a are provided. The plug sockets are connected via connecting wires 45b to lines of the second assembly 17, not shown.

Wenn bei der Darstellung nach Fig. 2 die Halterung 33 an dem Träger 29 fest positioniert ist, dann kann die erste Baugruppe 2 zunächst auf ein Prüfgerät aufgesetzt werden, welches dazu dient, die Funktionsfähigkeit der ersten Baugruppe zu überprüfen. Die Steckerstifte 41a gelangen beim Aufsetzen der ersten Baugruppe 2 auf eine nicht dargestellte Prüfvorrichtung auf ihnen zugeordnete Kontaktbuchsen des Prüfgerätes. Nach erfolgter Überprüfung wird die erste Baugruppe in das Gehäuse 1 eingesetzt und zunächst auf nicht dargestellte Weise mechanisch mit dem Gehäuse 1 verbunden. Die zweite Baugruppe 17 wurde schon zuvor in das Gehäuse eingebaut. Wird nun die erste Baugruppe nach der zweiten Baugruppe in das Gehäuse eingesetzt, dann gelangt das Steckelement 41 oberhalb des tief im Schacht 25 plazierten Einführtrichters 43. Bei dem festen Einbau der ersten Baugruppe 2 in das Gehäuse 1 erfolgt zunächst noch keine Kontaktierung. Diese Kontaktierung erfolgt erst, wenn die Halterung 33 in Richtung auf den Einführtrichter 43 niedergedrückt wird. Beim Niederdrücken wird die Halterung 33 vom Träger 29 entrastet. Unmittelbar nach der Entrastung hat die Halterung 33 innerhalb der Führungen 30 ein gewisses Spiel, wobei die Nuten 34 dafür sorgen, daß das Spiel begrenzt bleibt. Diese begrenzte Führung ist wichtig, damit die Halterung 33 mit dem Steckelement 41 immer vom Einführtrichter 43 mit schrägen Einführkanten 43a eingefangen werden kann. An die schrägen Kanten 43a schließen sich gerade verlaufende Einführkanten 43b an, die dafür sorgen, daß das eingefangene Steckelement 41 dann in das Steckelement 45 einfahren kann, so daß die Steckerstifte 41a zuverlässig mit den Steckerbuchsen 45a kontaktieren.If, in the illustration according to FIG. 2, the holder 33 is firmly positioned on the carrier 29, then the first assembly 2 can first be placed on a testing device which serves to check the functionality of the first assembly. When the first assembly 2 is placed on a test device (not shown), the connector pins 41a arrive at contact sockets of the test device assigned to them. After the check has been carried out, the first assembly is inserted into the housing 1 and first mechanically connected to the housing 1 in a manner not shown. The second assembly 17 has already been installed in the housing. Now becomes the first assembly inserted into the housing after the second assembly, then the plug element 41 arrives above the insertion funnel 43 placed deep in the shaft 25. When the first assembly 2 is firmly installed in the housing 1, no contact is initially made. This contacting takes place only when the holder 33 is pressed down in the direction of the insertion funnel 43. When pressed down, the holder 33 is released from the support 29. Immediately after unlocking, the holder 33 has a certain play within the guides 30, the grooves 34 ensuring that the play remains limited. This limited guidance is important so that the holder 33 with the plug-in element 41 can always be caught by the insertion funnel 43 with inclined insertion edges 43a. Straight bevelling edges 43b adjoin the inclined edges 43a, which ensure that the captured plug element 41 can then move into the plug element 45, so that the plug pins 41a make reliable contact with the plug sockets 45a.

Der Vorteil dieser Bauweise besteht nicht nur in der sicheren Kontaktierung am Boden des Schachtes 25 und das Auffangen der bereits erwähnten Toleranzen. Der weitere Vorteil besteht darin, daß bei evtl. Reparaturen die Halterung 33 von Hand hochgezogen werden kann mittels des Griffes 37, wodurch die Kontaktierung einwandfrei lösbar ist. Beim Hochziehen läßt sich die Verrastung wieder herbeiführen. Für die zuverlässige Bewegung dienen dabei wieder die Führungen 30. Die Enge des Schachtes 25 ist dabei für die Lösung der Kontakte kein Problem.The advantage of this design is not only the secure contacting at the bottom of the shaft 25 and the collection of the tolerances already mentioned. The further advantage is that the holder 33 can be pulled up by hand by means of the handle 37 in the event of repairs, so that the contacting can be released without problems. When pulling up, the locking can be brought back again. The guides 30 again serve for the reliable movement. The narrowness of the shaft 25 is not a problem for the solution of the contacts.

Reparaturen lassen sich auf diese Art und Weise schneller durchführen. Mit Hilfe der Vorrichtung 27 läßt sich sowohl das Kontaktieren als auch das Dekontaktieren ohne Schwierigkeiten durchführen. Für Massenfertigung ist diese Montageart außerordentlich günstig, insbesondere beim Einsatz von Robotern.Repairs can be carried out faster in this way. With the aid of the device 27, both contacting and decontacting can be carried out without difficulty. This type of assembly is extremely cheap for mass production, especially when using robots.

Die Vorrichtung 27 dient beispielsweise der Kontaktierung des Motors 8, um so über die zweite Baugruppe 17 die Laufwerksfunktionen der ersten Baugruppe 2 steuern zu können.The device 27 is used, for example, to contact the motor 8 so that the drive functions of the first module 2 can be controlled via the second module 17.

Wie schon erwähnt, ist eine zweite Vorrichtung 28 vorgesehen, mit der eine weitere Kontaktierung möglich ist. Diese Kontaktierung dient dem elektrischen Anschluß des Magnetkopfes 10 mit der zweiten Baugruppe 17. Die zweite Vorrichtung 28 entspricht in ihrer Funktionsweise im wesentlichen der ersten Vorrichtung 27. Die Vorrichtung 28 weist dazu einen Träger 46 auf, der fest mit dem Chassis 3 verbunden ist. Der Träger 46 weist Nuten 47 auf, die einander gegenüberliegen und aufeinander zuweisen. Die Nuten 47 sind im Bereich des Nutgrundes mit Mulden 48 versehen, in die Rastnasen 49 eine Halterung 50 einrasten können. Der Träger besteht aus einem rechteckigen Rahmen 51. An der Halterung 50 ist ein Bandkabel 52 angeordnet, das elektrisch kontaktiert ist mit Steckbahnen 53, die gemeinsam mit der Halterung 50 ein Steckelement 54 bilden. Ränder 51b des Rahmens 51 bilden Führungen innerhalb der Nuten 47.As already mentioned, a second device 28 is provided, with which further contacting is possible. This contacting serves for the electrical connection of the magnetic head 10 to the second assembly 17. The function of the second device 28 essentially corresponds to that of the first device 27. For this purpose, the device 28 has a carrier 46 which is fixedly connected to the chassis 3. The carrier 46 has grooves 47 which lie opposite one another and face one another. The grooves 47 are provided in the area of the groove base with troughs 48, into which latches 49 a holder 50 can snap. The carrier consists of a rectangular frame 51. A ribbon cable 52 is arranged on the holder 50 and is electrically contacted with plug-in tracks 53, which together with the holder 50 form a plug-in element 54. Edges 51b of the frame 51 form guides within the grooves 47.

An der zweiten Baugruppe 17 ist wieder ein Einführtrichter 55 vorgesehen, der sich mit einer Klammerverbindung 56 an der zweiten Baugruppe 17 festklammert. Im wesentlichen entspricht der Einführtrichter 55 dem Einführtricher 43 nach Fig. 2. In ihm ist ein Steckelement 57 vorgesehen, das Kontaktfedern 58 aufweist. Genauso wie bei der esten Vorrichtung 27 läßt sich nach dem mechanischen Verbinden der ersten Baugruppe 2 im Gehäuse 1 durch Niederfahren der Halterung 50 eine Kontaktierung des Steckelement 54 mit dem Steckelement 57 herbeiführen. Auf gleiche Weise gleicht auch der Trichter 55 Toleranzen zwischen den Baugruppen aus. Die Funktionsweise entspricht vollends der nach Fig. 2, und es läßt sich mit Hilfe der Vorrichtung 28 also wieder sowohl eine Prüfung bei festgesteckter Halterung 50 als auch eine Kontaktierung bei niedergedrückter Halterung 50 als auch eine Reparatur durch nachträgliches Hochziehen der Halterung 50 und wieder Niederfahren durchführen.On the second assembly 17, an insertion funnel 55 is again provided, which clings to the second assembly 17 with a clamp connection 56. The insertion funnel 55 essentially corresponds to the insertion funnel 43 according to FIG. 2. A plug element 57 is provided in it, which has contact springs 58. Just as in the first device 27, after the mechanical connection of the first assembly 2 in the housing 1, the plug element 54 can be brought into contact with the plug element 57 by moving the holder 50 down. In the same way, the funnel 55 compensates for tolerances between the assemblies. The operation corresponds completely to that of FIG. 2, and it can thus be carried out with the aid of the device 28 again both a test with the holder 50 pinned and a contact when the holder 50 is depressed, as well as a repair by subsequently lifting the holder 50 and moving it down again .

Auf die Halterung 50 ist ein Kunststoffteil aufgesteckt, das einen Anschlag 59 aufweist, der sich parallel zur Oberkante der Halterung 50 erstreckt und sie beidseitig überragt, so daß die Halterung 50 aus dem Steckelement 57 herausgehoben wird, wenn beim Entnehmen der Baugruppe 17 die Oberkante des Trägers 46 gegen den Anschlag 58 stößt.A plastic part is attached to the bracket 50, which has a stop 59 which extends parallel to the upper edge of the bracket 50 and projects beyond it on both sides, so that the bracket 50 is lifted out of the plug element 57 when the upper edge of the Carrier 46 abuts the stop 58.

An dem Kunststoffteil ist ein gekrümmter Schutzbügel 60 vorgesehen, der einen Schutz für das flexible elektrische Bandkabel 52 bildet. Der Schutzbügel 59 reicht vom Anschlag 59 bis in die Nähe der Steckbahnen 53. Der Schutzbügel wird an dem Rahmen 51 mittels Klemmbacken 61 und 62a, 62b verklemmt. Die Klemmbacken 61, 62a, 62b sind an den Schutzbügel 60 angespritzt.A curved protective bracket 60 is provided on the plastic part and forms a protection for the flexible electrical ribbon cable 52. The protective bracket 59 extends from the stop 59 to the vicinity of the plug-in tracks 53. The protective bracket is clamped to the frame 51 by means of clamping jaws 61 and 62a, 62b. The clamping jaws 61, 62a, 62b are molded onto the protective bracket 60.
