Description

Die Erfindung bezieht sich auf eine Adpatereinrichtung zur Herstellung einer lösbaren elektrischen Verbindung zwischen Kontaktelementen eines ersten elektrischen Bauteils, z.B. eines zu prüfenden Bausteins, und Kontaktelementen eines zweiten elektrischen Bauteils, z.B. eines Prüfautomaten.The invention relates to an adapter device for establishing a releasable electrical connection between contact elements of a first electrical component, e.g. of a component to be tested, and contact elements of a second electrical component, e.g. of an automatic tester.

Elektrische Bauteile, z.B. Flachbaugruppen und Bausteine, die eine Vielzahl von elektronischen Bauelementen enthalten können, müssen vor dem Einbau z.B. in ein Datenverarbeitungssystem auf Fehlerfreiheit geprüft werden. Dazu werden sie in einen Prüfautomaten eingeführt, der die zur Prü- fung des elektrischen Bauteils, im folgenden Prüfling genannt, erforderlichen Prüfsignale erzeugt und die vor dem Prüfling abgegebenen Ausgangssignale überprüft. Zu diesem Zwecke muß eine elektrische Verbindung zwischen dem Prüfautomaten und dem Prüfling hergestellt werden.Electrical components, such as printed circuit boards and modules, which can contain a large number of electronic components, must be checked for errors before being installed, for example, in a data processing system. For this purpose, they are introduced in a test automaton which g fun to the Prü- of the electrical component, hereinafter referred to as device under test generates test signals required, and checks the output of DUT output signals. For this purpose, an electrical connection must be made between the test machine and the device under test.

.Da mit einem Prüfautomaten verschiedenartig aufgebaute Prüflinge geprüft werden müssen, kann der Prüfling nicht direkt an die Anschaltebaugruppen des Prüfautomaten angeschaltet werden. Vielmehr muß zwischen den Anschaltebaugruppen des Prüfautomaten und dem Prüfling eine Adaptereinrichtung angeordnet werden. Mit Hilfe dieser Adaptereinrichtung werden die Leitungen der Anschaltebaugruppen mit den zugeordneten Leitungen des Prüflings verbunden. Wenn also ein anders aufgebauter Prüfling geprüft werden soll, ist es lediglich erforderlich, die Adaptereinrichtung oder ein Teil der Adaptereinrichtung auszutauschen, die übrigen Einheiten des Prüfautomaten müssen dagegen nicht geändert werden. Die Adaptereinrichtung ist also sowohl mit den Anschaltebaugruppen des Prüfautomaten als auch mit dem Prüfling in elektrischer Verbindung und ist so aufgebaut; daß die Signalleitungen und Potentialleitungen der Anschaltebaugruppen des Prüfautomaten mit den zugeordneten Signalleitungen und Potentialleitungen des Prüflings verbunden werden.Since test objects of different types have to be tested with an automatic test machine, the test object cannot be directly connected to the interface modules of the automatic test machine. Rather, an adapter device must be arranged between the connection modules of the automatic test machine and the test object. With the help of this adapter device, the lines of the interface modules are connected to the assigned lines of the test object. So if a differently designed test object is to be tested, it is only necessary to replace the adapter device or part of the adapter device, the other units of the testing machine do not have to be changed. The adapter device is therefore both in electrical connection with the connection modules of the automatic test machine and with the test object and is constructed in this way; that the signal lines and potential lines of the connection modules of the automatic test machine are connected to the assigned signal lines and potential lines of the test object.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine Adaptereinrichtung anzugeben, mit der eine lösbare, leitungsrichtige elektrische Verbindung zwischen einem ersten elektrischen Bauteil, z.B. dem Prüfling, und einem zweiten elektrischen Bauteil, z.B. einem Prüfautomaten, herstellbar ist, die einfach und kostengünstig ausgeführt ist. Diese Aufgabe wird bei einer Adaptereinrichtung der eingangs angegebenen Art dadurch gelöst, daß eine auswechseltare Leiterplatte vorgesehen ist, die Durchkontaktierungen im Rastermaß der Kontaktelemente des ersten Bauteils aufweist, die Kontaktstellen im Rastermaß der Kontaktelemente des zweiter Bauteils aufweist, und die Verbindungsleitungen zwischen den Durchkontaktierurgen und den Kontaktelementen aufweist und daß in den Durchkontaktierungen relativ zu der Leiterplatte verschiebbare Verbindungsteile angeordnet sind, durch deren Verschiebung elektrischer Kontakt zwischen den Kontaktelementen des ersten Bauteils und den Verbindungselementen und elektrischer Kontakt zwischen den Verbindungselementen und den Durchkontaktierungen herstellbar ist.The object on which the invention is based is to specify an adapter device with which a releasable, correct electrical connection between a first electrical component, for example the test object, and a second electrical component, for example an automatic test machine , can be produced, which is simple and inexpensive . This object is achieved in an adapter device of the type specified in the introduction in that an exchangeable circuit board is provided which has vias in the pitch of the contact elements of the first component, the contact points in the pitch of the contact elements of the second component, and the connecting lines between the vias and the Has contact elements and that displaceable connecting parts are arranged in the plated-through holes, the displacement of which makes it possible to produce electrical contact between the contact elements of the first component and the connecting elements and electrical contact between the connecting elements and the plated-through holes.

Durch die Verschiebung der Verbindungsteile relativ zu der Leiterplatte ist weiterhin Kontakt zwischen der Leiterplatte und den Kontaktelementen des zweiten Bauteils herstellbar. Somit sind zur Kontaktierung zwischen den Kontaktelementen, der Leiterplatte und den Kontaktelementen des zweiten Bauteils keine weiteren, zusätzlichen Bauteile erforderlich.By shifting the connecting parts relative to the circuit board, contact between the circuit board and the contact elements of the second component can still be established. Thus, for contacting between the contact elements, the circuit board and the contact elements of the second component, no further, additional components are required.

Ein einfach ausgeführtes Verbindungsteil ist am einen Ende zur Aufnahme eines als Kontaktstift ausgeführten Kontaktelements des ersten Bauteils als Steckhülse ausgeführt und ist am anderen Ende im Kontaktbereich zur Durchkontaktierung aufgespreizt. Ein solches Verbindungsteil besteht aus einem Rohr, das am anderen Ende aufgeschlitzt und aufgespreizt ist und aus einem Stift, der in dem Rohr in Kontakt mit diesem angeordnet ist und am einen Ende als Steckhülse ausgeführt ist.A simply designed connecting part is designed as a plug-in sleeve at one end for receiving a contact element of the first component designed as a contact pin and is spread apart at the other end in the contact area for through-plating. Such a connecting part consists of a tube which is slit and spread at the other end and of a pin which is arranged in contact with the tube and is designed as a plug-in sleeve at one end.

Ein weiteres einfach ausgeführtes Verbindungsteil ist am einen Ende als Steckstift ausgeführt und am anderen Ende im Kontaktbereicn zur Durchkontaktierung aufgespreizt. Ein solches Verbindungsteil besteht aus einem Rohr, das am anderen Ende aufgeschlitzt und auf gespreizt ist und aus einem Stift, der im Rohr in Kontakt mit diesem angeordnet ist und am einen Ende als Steckstift ausgeführt ist.Another simply designed connecting part is designed as a plug pin at one end and spread at the other end in the contact area for through-plating. Such a connecting part consists of a tube which is slit open and spread at the other end and a pin which is arranged in contact with the tube and is designed as a plug pin at one end.

Es ist zweckmäßig, wenn der Stift am anderen Ende des Rohres herausragt, so daß eine Bewegungsmechanik an diesem Ende angreifen kann.It is useful if the pin protrudes from the other end of the tube so that a movement mechanism can attack at this end.

Zur Herstellung der elektrischen Verbindung zwischen dem ersten Bauteil, dem Prüfling, und dem zweiten Bauteil, dem Prüfautomat, kann folgendermaßen vorgegangen werden. Zunächst wird die Leiterplatte in einer ersten Richtung bei stillstehenden Verbindungsteilen verschoben, um Kontakt zwischen den Kontaktflecken der Leiterplatte und den Kontaktelementen des Prüfautomaten herzustellen. Anschließend werden die Verbindungsteile in entgegengesetzter Richtung durch die Durchkontaktierungen der Leiterplatte soweit geschoben, daß Kontakt zwischen den Verbindungsteilen und den Kontaktelementen des ersten Bauteils, des Prüflings, hergestellt ist und Kontakt zwischen den Durchkontaktierungen und den Verbindungsteilen besteht.The following procedure can be used to establish the electrical connection between the first component, the test object, and the second component, the automatic test machine. First, the circuit board is moved in a first direction when the connection parts are stationary in order to make contact between the contact pads of the circuit board and the contact elements of the automatic test machine. Then the connecting parts are pushed in the opposite direction through the plated-through holes of the printed circuit board to such an extent that contact between the connecting parts and the contact elements of the first component, the test piece, is produced and there is contact between the plated-through holes and the connecting parts.

Diese einfach und kostengünstig ausgeführte Adaptereinrichtung besteht somit im wesentlichen aus der Leiterplatte, deren Kontaktelemente im:Rastermaß sowohl dem Prüfling als auch dem Prüfautomaten einfach angepaßt werden können. Diese Leiterplatte wird dann relativ zu den Verbindungsteilen, dem Prüfling und dem Prüfautomaten verschoben, um Kontakt herzustellen. Eine derart ausgeführte Leiterplatte ist sehr kostengünstig und kann leicht ausgetauscht werden.This simple and inexpensive adapter device thus essentially consists of the printed circuit board, the contact elements of which can be easily adapted to the test object as well as the automatic test machine in the grid dimension. This circuit board is then moved relative to the connecting parts, the test specimen and the testing machine in order to make contact. Such a printed circuit board is very inexpensive and can be easily replaced.

The invention is further explained on the basis of an exemplary embodiment which is illustrated in the figures. It newspaper g s

Die Adaptereinrichtung nach Figur 1 besteht aus einer Leiterplatte 1, und Verbindungsteilen 7. Die Leiterplatte 1 enthält Durchkontaktierungen 2, in die die Verbindungsteile 7 eingeschoben werden können. Die Durchkontaktierungen 2 sind im Rastermaß der Kontaktelemente eines Prüflings 3 angeordnet. Der Prüfling 3 kann z.B. eine Flachbaugruppe sein, die mit einem Stecker 12 versehen ist, dessen Kontaktstifte 13 mit den Verbindungsteilen 7 verbunden werden müssen.The adapter device according to FIG. 1 consists of a printed circuit board 1 and connecting parts 7. The printed circuit board 1 contains plated-through holes 2 into which the connecting parts 7 can be inserted. The plated-through holes 2 are arranged in the grid dimension of the contact elements of a test object 3. The test specimen g 3 can be, for example, a printed circuit board be provided with a plug 12, the contact pins 13 of which must be connected to the connecting parts 7.

Auf der Leiterplatte 1 sind weiterhin Kontaktflecken 4 angeordnet, über die Kontakt mit Kontaktstiften 5 des Prüfautomaten hergestellt wird. Diese Kontaktflecken 4 sind im Rastermaß der Kontaktelemente des Prüfautomaten auf der Leiterplatte 1 angeordnet. Zwischen den Durchkontaktierungen 2 und den Kontaktflecken 4 sind elektrische Leitungen 6 angeordnet.Contact patches 4 are also arranged on the printed circuit board 1, via which contact is made with contact pins 5 of the testing machine. These contact pads 4 are arranged on the circuit board 1 in the grid dimension of the contact elements of the automatic test machine. Electrical lines 6 are arranged between the plated-through holes 2 and the contact pads 4.

Die elektrische Verbindung zwischen dem Prüfling'3 und der Leiterplatte 1 erfolgt mit Hilfe des Verbindungsteils 7. Diese Verbindungsteile 7 stellen eine Steckverbindung von der Durchkontaktierung 2 in der Leiterplatte 1 zu dem Stekker 12 des Prüflings 3 her. Die.Verbindungsteile 7 sind aber mit der Leiterplatte 1 nicht fest verbunden, sie können daher in Pfeilrichtung 8 relativ zu der Leiterplatte 1 bewegt werden. Bei dieser Bewegung relativ zur Leiterplatte 1 kann Kontakt zwischen dem Stecker 12 des Prüflings 3 und den Verbincungsteilen 7 als auch zwischen den Verbi.ndungsteilen 7 und den Durchkontaktierungen 2 der Leiterplatte 1 hergestellt werden.The electrical connection between the test specimen 3 and the printed circuit board 1 takes place with the aid of the connecting part 7. These connecting parts 7 establish a plug connection from the plated-through hole 2 in the printed circuit board 1 to the plug 12 of the test specimen 3. The connecting parts 7 are not firmly connected to the circuit board 1, however, they can therefore be moved in the direction of the arrow 8 relative to the circuit board 1. During this movement relative to the printed circuit board 1, contact can be made between the plug 12 of the test specimen 3 and the connecting parts 7 and also between the connecting parts 7 and the plated-through holes 2 of the printed circuit board 1.

Diesen Bewegungsvorgang zeigt Figur 2 und Figur 3. Figur 2 stellt den Zustand dar, bei dem das Verbindungsteil 7 noch nicht den elektrischen Kontakt zwischen dem Kontaktstift 13 und der Durchkontaktierung 2 hergestellt hat. Zu diesem Zwecke muß das Verbindungsteil 7 in die Durchkontaktierung 2 hineingeschoben werden, wie es in Figur 3 gezeigt ist. Dabei entsteht Steckverbindung zwischen dem Kontaktstift 13 des Prüflings 3 und der Durchkontaktierung 2.This movement process is shown in FIG. 2 and FIG. 3. FIG. 2 shows the state in which the connecting part 7 has not yet made the electrical contact between the contact pin 13 and the via 2. For this purpose, the connecting part 7 must be pushed into the via 2, as shown in Figure 3. This creates a plug connection between the contact pin 13 of the test specimen 3 and the through-connection 2.

Um den nötigen Kontakt zwischen dem Verbindungsteil 7 und der Durchkontaktierung 2 herstellen zu können, ist das Verbindungsteil 7 am einen Ende aufgespreizt. Bei der Bewegung des Verbindungsteils 7 zum Stecker 13 des Prüflings 3 wird das Verbindungsteil mit dem aufgespreizten Ende in die Durchkontaktierung 2 hineingeschoben und es entsteht Kontakt zwischen dem Verbindungsteil 7 und der Durchkontaktierung 2. yIn order to be able to establish the necessary contact between the connecting part 7 and the through-contact 2, the connecting part 7 is spread out at one end. When the connecting part 7 moves to the plug 13 of the test specimen 3, the connecting part with the spread-open end is pushed into the through-contact 2 and contact is created between the connecting part 7 and the through-contact 2. y

Die elektrische Verbindung zwischen den Kontaktstiften 13 des Prüflings 3 und den Kontaktstiften 5 des Prüfautomaten kann auf folgende Weise hergestellt werden: Zunächst wird die Leiterplatte 1 in Richtung des Pfeils 9 relativ zu den Verbindungsteilen 7 solange verschoben, bis die Kontaktstifte 5 mit den Kontaktflecken 4 auf der Leiterplatte 1 Kontakt haben. Bei diesem Verschiebevorgang wird noch kein Kontakt zwischen den Verbindungsteilen 7 und den Kontaktstiften 13 des Prüflings 3 und den Verbindungsteilen 7 und den Durchkontaktierungen 2 hergestellt. In dieser Position kann die Leiterplatte 1 bleiben, solange Prüflinge gleichen Aufbaus geprüft werden. Zur Herstellung der elektrischen Verbindung zwischen dem Prüfling 3 und der Leiterplatte 1 werden nun die Verbindungsteile 7 in Richtung des Pfeils 8 zu dem Prüfling 3 hinbewegt. Dadurch entsteht ein Kontakt zwischen den Kontaktstiften 13 des Prüflings 3 und den als Steckhülsen ausgeführten Enden der Verbindungsteile 7. Weiterhin entsteht Kontakt zwischen den Durchkontaktierungen 2 und den aufgespreizten Teilen der Verbindungsteile 7.The electrical connection between the contact pins 13 of the device under test 3 and the contact pins 5 of the automatic test machine can be established in the following way: First, the circuit board 1 is shifted in the direction of the arrow 9 relative to the connecting parts 7 until the contact pins 5 with the contact pads 4 are open the circuit board 1 have contact. During this displacement process, no contact is made between the connecting parts 7 and the contact pins 13 of the test specimen 3 and the connecting parts 7 and the plated-through holes 2. The circuit board 1 can remain in this position as long as test objects of the same structure are tested. To establish the electrical connection between the device under test 3 and the circuit board 1, the connecting parts 7 are now moved in the direction of the arrow 8 toward the device under test 3. This creates a contact between the contact pins 13 of the test specimen 3 and the ends of the connecting parts 7 designed as plug sleeves. Furthermore, there is contact between the plated-through holes 2 and the expanded parts of the connecting parts 7.

Zur Lösung des Kontaktes zwischen dem Prüfling 3 und der Leiterplatte 1 werden die Verbindungsteile 7 in entgegengesetzter Richtung aus den Durchkontaktierungen 2 der Leiterplatte 1 herausgezogen, dabei der Kontakt zwischen den Verbindungsteilen 7 und den Durchkontaktierungen 2 und zwischen den Verbindungsteilen 7 und den Steckstiften des Prüflings 3 gelöst.To solve the contact between the device under test 3 and the circuit board 1, the connecting parts 7 are pulled out in the opposite direction from the plated-through holes 2 of the printed circuit board 1, the contact between the connecting parts 7 and the plated-through holes 2 and solved between the connecting parts 7 and the pins of the device under test 3.

Zur Kontaktierung eines Prüflings ist somit nur die Bewegung der Verbindungsteile 7 relativ zur Leiterplatte 1. erforderlich. Die Bewegung der Leiterplatte 1 zu den Kontaktstiften 5 des Prüfautomaten ist nur dann erforderlich, wenn eine neue Leiterplatte 1 eingesetzt werden muß. Dies ist z.B. dann der Fall, wenn ein anders aufgebauter Prüfling 3 geprüft werden soll.To contact a test specimen, therefore, only the movement of the connecting parts 7 relative to the printed circuit board 1 . required. The movement of the circuit board 1 to the contact pins 5 of the automatic test machine is only required if a new circuit board 1 has to be used. This is the case, for example, when a test object 3 with a different structure is to be tested.

Der genauere Aufbau eines Verbindungsteils ist in den Figuren 4 bis 6 gezeigt. Das Verbindungsteil 7 weist zwei Bestandteile auf, es enthält ein Rohr 14, das am einen Ende 17 geschlitzt und aufgespreizt ist. In diesem Rohr 14 ist ein Stift 15 angeordnet. Dieser Stift 15 ist in Figur 4 und Figur 6 so ausgeführt, daß er am einen Ende eine Steckhülse 18 aufweist. In diese Steckhülse 15 kann ein Kontaktstift eingeschoben werden. Am anderen Ende des Ronres 14 ragt der Stift 15 heraus, so daß eine Bewegungsmechanik an dieser Seite am Stift angreifen kann. Um Kontakt zwischen dem Stift 15 und dem Rohr 14 herzustellen, sind beide Teile des Verbindungsteils im Bereich 16 mit Kerben zusammengeprägt.The more precise construction of a connecting part is shown in FIGS. 4 to 6. The connecting part 7 has two components, it contains a tube 14 which is slotted and spread at one end 17. A pin 15 is arranged in this tube 14.
