The contact element carrier (2) is constructed from individual, mutually parallel subassemblies (2a, 2b) which are pressed into a printed circuit board, so that any defective contact elements can be replaced, after unlocking the contact strip and the contact element carrier and removing the contact strip, simply by removing the relevant subassembly. <IMAGE>

Description

Die Erfindung betrifft einen um 90° abgewinkelten Steckverbinder für die Einpreßtechnik, mit einer aus Isoliermaterial bestehenden, in zueinander parallelen Reihen und Spalten Kontaktelemente aufnehmenden Kontaktleiste mit einer Steckseite und einer hierzu gegenüberliegenden Anschlußseite, und mit einem aus Isoliermaterial berstehenden, an der Anschlußseite der Kontaktleiste angefügten Kontaktelementeträger, dessen Kontaktelemente mit ihrem Steckbereich in die Kontaktleiste ragen und an ihrem rechtwinklig zur Steckrichtung verlaufenden Anschlußbereich als Einpreßstifte ausgebildet sind.The invention relates to a connector angled by 90 ° for the press-in technology, with a contact strip made of insulating material and receiving contact elements in parallel rows and columns with a plug-in side and an opposite connection side, and with a protruding from insulating material and attached to the connection side of the contact strip Contact element carrier, the contact elements of which protrude with their plug-in area into the contact strip and are designed as press-in pins on their connection area running at right angles to the plug-in direction.

Ein derartiger Steckverbinder ist durch das DE-GM 90 13 007 bekannt. Hierbei ist der Steckverbinder von einem die Kontaktleiste bildenden Hauptkörper und einem die Kontaktelemente tragenden, block- oder scheibenförmigen Zusatzkörper gebildet, von einer Blechverkleidung umgeben und in Einpreßtechnik an einer Leiterplatte befestigt. Der Steckverbinder wird auf einmal in die Leiterplatte eingepreßt, so daß bei hochpoligen Steckverbindern mit z.B. 100 bis 500 Polen sehr hohe Einpreßkräfte aufzuwenden sind, die bei nicht ausreichend genau ausgerichteten Einpreßstiften zu deren Beschädigung führen können. Es müssen daher vor dem Einpressen entsprechende Maßnahmen getroffen werden, um derartige Schäden zu verhindern. In der Regel ist der Einpreßvorgang der letzte Arbeitsschritt, so daß eine Leiterplatte oder Baugruppe bereits mit teueren Komponenten bestückt sein kann. Für den Fall, daß der Steckverbinder repariert werden muß oder einzelne Kontaktelemnte ersetzt werden müssen, besteht - insbesondere bei hochpoligen Steckverbindern - beim Auspressen des gesamten Steckverbinders aufgrund der hohen Auspreßkräfte die Gefahr einer Beschädigung oder gar Zerstörung der hochwertigen Baugruppe.Such a connector is known from DE-GM 90 13 007. Here, the connector is formed by a main body forming the contact strip and a block or disc-shaped additional body carrying the contact elements, surrounded by a sheet metal cladding and fastened to a printed circuit board using press-fit technology. The plug connector is pressed into the printed circuit board at once, so that very high press-in forces have to be applied to multi-pin plug connectors with, for example, 100 to 500 poles, which can lead to their damage if the press-in pins are not aligned precisely enough. Appropriate measures must therefore be taken before pressing in to prevent such damage. As a rule, the press-in process is the last step, so that a circuit board or assembly can already be equipped with expensive components. In the event that the connector has to be repaired or individual contact elements have to be replaced, there is - especially with multi-pin connectors - when pressing the entire connector due to the high extrusion forces the risk of damage or even destruction of the high-quality assembly.

Aus der DE-PS 39 25 958 ist ebenfalls ein Steckverbinder in Einpreßtechnik bekannt, der aus zwei durch geeignete Rastmittel miteinander verbundenen Isolierkörperhälften besteht. Hierbei können zwar die von der einen Isolierkörperhälfte gebildete Kontaktleiste und der Kontaktelementeträger voneinander gelöst werden, jedoch sind die Kontaktelemente in einer einteilig ausgebildeten zweiten Isolierkörperhälfte angeordnet, die dann im Reparaturfalle oder bei Auswechslungen einzelner Kontaktelemente als Ganzes ausgepreßt werden muß.From DE-PS 39 25 958 a connector in press-in technology is also known, which consists of two insulating body halves connected by suitable locking means. In this case, the contact strip formed by the one insulating body half and the contact element carrier can be detached from one another, but the contact elements are arranged in a one-piece second insulating body half, which then has to be pressed out as a whole in the event of repair or when individual contact elements are replaced.

Durch die DE-OS 40 40 551 ist eine elektrische Verbinderanordnung mit aneinander anliegenden einzelnen Gehäusemodulen bekannt, an deren der Steckseite gegenüberliegender Anschlußseite eine Vielzahl von einzelnen, zueinander parallelen Anschlußunteranordnungen vorgesehen ist. Diese Anschlußunteranordnungen sind isolierende Träger der mit ihrem Steckbereich in die Gehäusemodule ragenden Kontaktelemente, welche an ihrem rechtwinklig zur Steckrichtung aus den Anschlußunteranordnungen herausragenden Anschlußbereich einen federnd nachgiebigen Abschnitt aufweisen. Nach dem Zusammenbau der einzelnen Gehäusemodule mit den Anschlußunteranordnungen lassen sich die Gehäusemodule und die Anschlüsse derart auf eine Schaltungsplatte aufsetzen, daß die federnd nachgiebigen Abschnitte in entsprechend ausgebildete Durchgangslöcher der Schaltungsplatte eingeführt werden. Dies bedeutet, daß auch bei dieser bekannten elektrischen Verbinderanordnung zuerst die Gehäusemodule und die Anschlußunteranordnungen zusammengebaut und dann als Ganzes in die Schaltungsplatte eingepreßt werden. Demnach ist auch hier die Reparatur der Verbinderanordnung oder die Auswechslung einzelner Kontaktelemente aufwendig.From DE-OS 40 40 551 an electrical connector arrangement with abutting individual housing modules is known, on the connector side opposite the connector side a plurality of individual, mutually parallel connection subassemblies is provided. These connection subassemblies are insulating supports of the contact elements projecting with their plug-in area into the housing modules, which have a resiliently flexible section on their connection area protruding at right angles to the plug-in direction from the connection sub-assemblies. After the individual housing modules have been assembled with the connection subassemblies, the housing modules and the connections can be placed on a circuit board in such a way that the resilient sections are inserted into correspondingly formed through holes in the circuit board. This means that even with this known electrical connector arrangement, the housing modules and the connection subassemblies are first assembled and then as a whole in the circuit board be pressed in. Accordingly, the repair of the connector arrangement or the replacement of individual contact elements is also complex here.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Steckverbinder der eingangs genannten Art den Aufbau so zu vereinfachen, daß eine Reparatur des Steckverbinders oder ein Auswechseln von Kontaktelementene in einfacher Weise möglich ist.The invention has for its object to simplify the structure of a connector of the type mentioned so that a repair of the connector or a replacement of contact elements is possible in a simple manner.

Diese Aufgabe wird bei einem Steckverbinder der eingangs genannten Art gemäß der Erfindung durch folgende Merkmale gelöst:

  • a) Der Kontaktelementeträger besteht aus einzelnen, die Kontaktelemente jeweils einer Spalte aufnehmenden, zueinander parallelen Unterbaugruppen
  • b) die Unterbaugruppen sind einzeln für sich in eine Leiterplatte eingepreßt und
  • c) die Kontaktleiste und der Kontaktelementeträger sind durch im Bereich der Anschlußseite der Kontaktleiste und durch an den Unterbaugruppen vorgesehene, zusammenwirkende Rastorgane lösbar miteinander verbunden.
This object is achieved in a connector of the type mentioned according to the invention by the following features:
  • a) The contact element carrier consists of individual subassemblies, which receive the contact elements in each case in a column and are parallel to one another
  • b) the subassemblies are individually pressed into a printed circuit board and
  • c) the contact strip and the contact element carrier are detachably connected to one another by means of cooperating latching members provided in the region of the connection side of the contact strip and by means of the subassemblies.

Bei einem derartigen Steckverbinder bestehen die Kontaktleiste und der Kontaktelementeträger aus lösbar mittels Rastorganen miteinander verbundenen Teilen, so daß sich die Kontaktleiste im Reparaturfalle einfach von dem Kontaktelementeträger abnehmen läßt. Dieser besteht aus einzelnen Unterbaugruppen, die jeweils eine Spalte von Kontaktelementen aufnehmen, zueinander parallel angeordnet und einzeln für sich in eine Leiterplatte eingepreßt sind. Dies bedeutet, daß nach dem Abnehmen der Kontaktleiste vom Kontaktelementeträger jede Unterbaugruppe einzeln für sich zugänglich und auspreßbar ist. Daher braucht bei einzelnen defekten Kontaktelementen lediglich die jeweilige Unterbaugruppe ausgepreßt zu werden, während die übrigen Unterbaugruppen eingepreßt bleiben und lagerichtig gehalten sind. Das Auspressen einer Unterbaugruppe oder mehrerer einzelner Unterbaugruppen kann infolge einer hierfür sehr kleinen Auspreßkraft manuell oder mit einem einfachen Hilfswerkzeug erfolgen. Auf dieselbe Weise wird eine neue Unterbaugruppe eingepreßt. Nach der Reparatur läßt sich die Kontaktleiste wieder auf den Kontaktelementeträger aufschieben. Eine Reparatur des Steckverbinders oder ein Auswechseln von Kontaktelementen ist somit in einfacher, kostengünstiger und schonender Weise ohne die Gefahr einer Baugruppenbeschädigung gewährleistet.In such a connector, the contact strip and the contact element carrier consist of parts releasably connected to one another by means of latching elements, so that the contact strip can be easily removed from the contact element carrier in the event of a repair. This consists of individual subassemblies, each of which accommodates a column of contact elements, is arranged parallel to one another and is individually pressed into a printed circuit board. This means that after the contact strip has been removed from the contact element carrier, each subassembly is individually accessible and is squeezable. Therefore, in the case of individual defective contact elements, only the respective subassembly needs to be pressed out, while the other subassemblies remain pressed in and are held in the correct position. A subassembly or several individual subassemblies can be pressed out manually or with a simple auxiliary tool as a result of a very small extrusion force for this purpose. A new subassembly is pressed in in the same way. After the repair, the contact strip can be pushed back onto the contact element carrier. A repair of the connector or a replacement of contact elements is thus ensured in a simple, inexpensive and gentle manner without the risk of damage to the assembly.

Die Erfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispieles eines Steckverbinders für die Einpreßtechnik näher erläutert. Es zeigen

  • Fig. 1 in explosionsartiger Darstellung die Einzelteile eines Steckverbinders,
  • Fig. 2 bis 6 in schematischer Darstellung den Steckverbinder im zusammengebauten, auf einer Leiterplatte angeordneten Zustand und die einzelnen Vorgänge beim Auswechseln von Kontaktelementen.
The invention is explained below with reference to an embodiment of a connector for the press-in technology shown in the drawing. Show it
  • 1 is an exploded view of the individual parts of a connector,
  • Fig. 2 to 6 in a schematic representation of the connector in the assembled, arranged on a circuit board state and the individual processes when replacing contact elements.

Der Steckverbinder ist aus zwei aus Isoliermaterial bestehenden Teilen, nämlich einer Kontaktleiste 1 und einem Kontaktelementeträger 2 (Fig.2) aufgebaut. Die Kontaktleiste ist entweder als Messerleiste mit stiftförmigen Messerkontakten oder als Federleiste mit buchsenartigen Kontaktfedern ausgebildet. In jedem Fall sind die Kontaktelemente in jeweils zueinander parallelen Reihen und Spalten in der Kontaktleiste 1 angeordnet. Im gezeigten Ausführungsbeispiel ist die Kontaktleiste 1 mit für den Betrachter der Fig. 1 an der vorderen Steckseite sichtbaren Kammern 3 für Kontaktfedern 4 und damit als Federleiste ausgebildet, wobei hier jeweils fünf Kammern in einer senkrechten Spalte untereinander angeordnet und z.B. 17 Spalten vorgesehen sind, d.h. es handelt sich hier um eine Federleiste mit fünf Reihen und 17 Spalten und demnach um einen 85-poligen Steckverbinder. An der der vorderen Steckseite gegenüberliegenden rückwärtigen Anschlußseite ist der Kontaktelementeträger 2 angefügt, der aus einzelnen, zueinander parallelen Unterbaugruppen 2a oder 2b (Fig.1) besteht, wobei jede Unterbaugruppe die Kontaktelemente jeweils einer Spalte aufnimmt. Die Unterbaugruppen 2a,2b sind demnach also Träger von fünf übereinander angeordneten Kontaktelementen 5, die mit ihrem die Kontaktfeder 4 aufweisenden Steckbereich in die Kammern 3 der Kontaktleiste 1 ragen und an ihrem rechtwinklig zur Steckrichtung verlaufenden Anschlußbereich von Verbindungsstielen 15 abragen und als Einpreßstift 6 ausgebildet sind. Die beiden Kontaktelementeträger 2a und 2b sind in unterschiedlicher Weise gestaltet und bilden zusammen mit jeweils gleichartigen Unterbaugruppen 2a oder 2b einen hier aus 17 zueinander parallelen Unterbaugruppen bestehenden Kontaktelementeträger 2. Die Unterbaugruppe 2a weist ein sich in Richtung einer Spalte erstreckendes Isolierteil 7 auf, das die in einer Spalte übereinander angeordneten Kontaktelemente 5 nur in einem relativ schmalen Bereich, der sich an den Steckbereich anschließt, aufnimmt, so daß die Kontaktelemente nur partiell von Isoliermaterial umgeben sind. Dagegen weist die Unterbaugruppe 2b ein sich in Richtung einer Spalte erstreckendes plattenförmiges Isolierteil 8 auf, das die in einer Spalte übereinander angeordneten Kontaktelemente 5 bis auf den Steck- und den Anschlußbereich vollständig umgibt. Das plattenförmige Isolierteil 8 besteht wie das Isolierteil 7 entweder aus einem einteiligen Spritzteil oder aus zwei lösbar miteinander verbundenen Einzelteilen 8a und 8b, welche die Kontaktelemente 5 zwischen sich einschließen.The connector is made up of two parts made of insulating material, namely a contact strip 1 and a contact element carrier 2 (FIG. 2). The contact strip is either a male connector with pin-shaped knife contacts or a female connector with socket-like contact springs educated. In any case, the contact elements are arranged in mutually parallel rows and columns in the contact strip 1. In the exemplary embodiment shown, the contact strip 1 is formed with chambers 3 for contact springs 4, which are visible on the front plug-in side for the viewer of FIG. 1, and thus as a spring strip, wherein here five chambers are arranged one below the other in a vertical column and, for example, 17 columns are provided, ie it is a female connector with five rows and 17 columns and therefore an 85-pin connector. The contact element carrier 2, which consists of individual, mutually parallel subassemblies 2a or 2b (FIG. 1), is attached to the rear connection side opposite the front plug side, each subassembly accommodating the contact elements in each case one column. The subassemblies 2a, 2b are therefore carriers of five superimposed contact elements 5, which protrude with their plug area having the contact spring 4 into the chambers 3 of the contact strip 1 and protrude from their connection area 15, which extends at right angles to the plugging direction, from connecting rods 15 and are designed as a press-in pin 6 . The two contact element carriers 2a and 2b are designed in different ways and, together with subassemblies 2a or 2b of the same type in each case, form a contact element carrier 2, which here consists of 17 mutually parallel subassemblies. The subassembly 2a has an insulating part 7 extending in the direction of a column, which has the insulation element shown in FIG a column of contact elements 5 arranged one above the other only in a relatively narrow area, which adjoins the plug-in area, so that the contact elements are only partially surrounded by insulating material. In contrast, the subassembly 2b has a plate-shaped insulating part 8 which extends in the direction of a column and which a column of contact elements 5 arranged one above the other completely except for the plug and the connection area. Like the insulating part 7, the plate-shaped insulating part 8 consists either of a one-piece injection-molded part or of two detachably connected individual parts 8a and 8b, which enclose the contact elements 5 between them.

Bei dem erfindungsgemäßen Steckverbinder wird jede Unterbaugruppe 2a bzw. 2b jeweils für sich in durchkontaktierte Bohrungen einer Leiterplatte 9 (Fig.2 bis 6) eingepreßt, bis der vollständige, hier entsprechend der Anzahl der Spalten in der Kontaktleiste 1 aus 17 Unterbaugruppen bestehende Kontaktelementeträger 2 gebildet ist. Dann wird die Kontaktleiste 1 auf den derart gebildeten Kontaktelementeträger 2 aufgeschoben, wobei die Kontaktleiste 1 und der Kontaktelementeträger 2 durch im Bereich der Anschlußseite der Kontaktleiste und durch an den Unterbaugruppen 2a,2b vorgesehene, zusammenwirkende Rastorgane 13,14 lösbar miteinander verbunden sind. Bei dem gezeigten Ausführungsbeispiel sind die Rastorgane 13,14 - wie Fig. 1 erkennen laßt - in einem dünnen, federnden Wandbereich 10 zumindest an der Oberseite 11 der Kontaktleiste und an der Oberseite 12 der Unterbaugruppen 2a bzw. 2b oder - wie die Fig.2 bis 6 erkennen lassen, an der Oberseite und an der Unterseite der Kontaktleiste 1 und der Unterbaugruppen 2b vorgesehen. Hier bestehen die Rastorgane aus an jeder Unterbaugruppe vorgesehenen Rastnasen 14, wobei für jede Rastnase jeweils ein Rastloch 13 in der Kontaktleiste 1 vorgesehen ist und die Rastnasen 14 an der der Kontaktleiste 1 zugewandten Seite abgeschrägt sind, so daß die Kontaktleiste leicht auf den von einer Vielzahl einzeln in die Leiterplatte 9 eingepreßter Unterbaugruppen 2b gebildeten Kontaktelementeträger 2 aufschiebbar und lösbar mit diesem verbunden ist (Fig.2). Im Falle der Reparatur des Steckverbinders oder des Auswechselns defekter Kontaktelemente wird die Kontaktleiste 1 durch Anheben der dünnen, federnden Wandbereiche 10 entriegelt und von dem Kontaktelementeträger 2 abgenommen (Fig.3). Dann wird die defekte Unterbaugruppe, z.B. die ein defektes Kontaktelement 5 oder mehrere defekte Kontaktelemente enthaltende vorderste Unterbaugruppe 2b des Kontaktelementeträgers 2 für sich ausgepreßt und aus dem Kontaktelementeträger herausgenommen (Fig. 4). Anstelle der defekten Unterbaugruppe wird einfach eine neue Unterbaugruppe in den Kontaktelementeträger 2 eingesetzt und in die Leiterplatte 9 eingepreßt (Fig.5). Abschließend wird die Kontaktleiste 1 wieder auf den Kontaktelementeträger 2 aufgeschoben und mit diesem verriegelt.In the connector according to the invention, each subassembly 2a or 2b is pressed into plated-through bores of a printed circuit board 9 (FIGS. 2 to 6) until the complete contact element carrier 2, consisting here of 17 subassemblies in accordance with the number of columns in the contact strip 1, is formed is. Then the contact strip 1 is pushed onto the contact element carrier 2 formed in this way, the contact strip 1 and the contact element carrier 2 being detachably connected to one another by cooperating latching elements 13, 14 provided in the region of the connection side of the contact strip and by means of the subassemblies 2a, 2b. In the embodiment shown, the locking members 13, 14 - as can be seen in FIG. 1 - are in a thin, resilient wall area 10 at least on the top 11 of the contact strip and on the top 12 of the subassemblies 2a or 2b or - as in FIG. 2 to 6 can be seen, provided on the top and on the bottom of the contact strip 1 and the subassemblies 2b. Here, the locking members consist of locking lugs 14 provided on each subassembly, a locking hole 13 being provided in the contact strip 1 for each locking lug, and the locking lugs 14 being chamfered on the side facing the contact strip 1, so that the contact strip can be easily attached to a plurality contact element carrier 2, which is formed individually into the printed circuit board 9 of subassemblies 2b, can be pushed on and releasably connected to the latter (FIG. 2). In case of repair of the connector or replacing defective contact elements, the contact strip 1 is unlocked by lifting the thin, resilient wall areas 10 and removed from the contact element carrier 2 (FIG. 3). Then the defective subassembly, for example the foremost subassembly 2b of the contact element carrier 2 containing a defective contact element 5 or more defective contact elements, is pressed out for itself and removed from the contact element carrier (FIG. 4). Instead of the defective subassembly, a new subassembly is simply inserted into the contact element carrier 2 and pressed into the printed circuit board 9 (FIG. 5). Finally, the contact strip 1 is pushed back onto the contact element carrier 2 and locked with it.
