Description

Beschreibungdescription
Leiterplatten-SteckverbinderPCB connector
Die vorliegende Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1, d.h. einen Leiterplatten- Steckverbinder zum Verbinden einer ersten Leiterplatte und einer im wesentlichen senkrecht auf diese aufsteckbaren zweiten Leiterplatte, wobei der Leiterplatten-Steckverbinder auf der ersten Leiterplatte montiert ist, und wobei der Leiterplatten-Steckverbinder derart ausgebildet ist, daß er mit auf gegenüberliegenden Seiten der zweiten Leiterplatte vorgesehenen elektrischen Verbindern in Kontakt bringbar ist.The present invention relates to a device according to the preamble of claim 1, i.e. a printed circuit board connector for connecting a first printed circuit board and a second printed circuit board which can be plugged substantially perpendicularly thereto, the printed circuit board connector being mounted on the first printed circuit board, and the printed circuit board connector being designed such that it mates with on opposite sides of the second Printed circuit board provided electrical connectors can be brought into contact.
Leiterplatten-Steckverbinder, die dazu ausgelegt sind, mit auf gegenüberliegenden Seiten einer Leiterplatte vorgesehenen elektrischen Verbindern in Kontakt gebracht zu werden, sind erforderlich, weil die Anzahl der Kontakte, die Leiterplatten-Steckverbinder aufweisen müssen, immer v/eiter steigt; über beiderseits einer Leiterplatte vorgesehene elektrische Verbinder können - bezogen auf die Länge der elektrischen Verbinder (der Leiterplatte) - mehr Kontakte untergebracht werden als wenn nur auf einer Seite der Leiterplatte ein elektrischer Verbinder vorgesehen wäre.Printed circuit board connectors which are designed to be brought into contact with electrical connectors provided on opposite sides of a printed circuit board are required because the number of contacts which printed circuit board connectors must have is always increasing; With regard to the length of the electrical connector (the circuit board), more contacts can be accommodated via electrical connectors provided on both sides of a circuit board than if an electrical connector were provided only on one side of the circuit board.
Die Herstellung derartiger Leiterplatten-Steckverbinder erfordert wegen der sehr großen Anzahl von in der Regel sehr dicht angeordneten Kontakten, über welche sie mit darauf aufzusteckenden Leiterplatten und mit der sie tragenden Leiter- platte in Verbindung zu bringen sind, höchste Präzision. Dies gilt in besonderem Maße, wenn die Verbindung zwischen dem Leiterplatten-Steckverbinder und der diesen tragenden Leiterplatte nach einem SMT-Verfahren erfolgt (der Leiterplatten- Steckverbinder ein oberflächenmontierbarer Leiterplatten- Steckverbinder ist) . Entsprechendes gilt für die auf den Leiterplatten-Steckverbinder aufzusteckende Leiterplatte und die Montage der auf dieser vorgesehenen elektrischen Verbinder.The production of such printed circuit board connectors requires the highest precision because of the very large number of contacts which are usually arranged very densely and via which they can be connected to printed circuit boards to be plugged onto them and to the printed circuit board carrying them. This applies in particular if the connection between the printed circuit board connector and the printed circuit board carrying it is made using an SMT process (the printed circuit board connector is a surface-mountable printed circuit board connector). The same applies to the circuit board to be plugged onto the circuit board connector and the assembly of the electrical connectors provided on it.
ERZSATZBLATT (REGEL 26) Unabhängig davon sind Leiterplatten-Steckverbinder der eingangs genannten Art auch nur sehr schwer handhabbar.REPLACEMENT BLADE (RULE 26) Regardless of this, circuit board connectors of the type mentioned at the outset are also very difficult to handle.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, den Leiterplatten-Steckverbinder gemäß dem Oberbegriff des Patentanspruchs 1 derart weiterzubilden, daß dieser auch bei höchsten Qualitäts- und Zuverlässigkeitsanforderungen relativ einfach herstellbar und handhabbar ist.The present invention is therefore based on the object of further developing the printed circuit board connector in accordance with the preamble of patent claim 1 in such a way that it can be manufactured and handled relatively easily, even with the highest quality and reliability requirements.
Diese Aufgabe wird erfindungsgemäß durch das im kennzeichnenden Teil des Patentanspruchs 1 beanspruchte Merkmal gelöst.This object is achieved by the feature claimed in the characterizing part of claim 1.
Demnach ist vorgesehen, daß der Teil des Leiterplatten- Steckverbinders, der mit dem auf der einen Seite der zweiten Leiterplatte vorgesehenen elektrischen Verbinder in Verbindung zu bringen ist, und der Teil des Leiterplatten- Steckverbinders, der mit dem auf der anderen Seite der zweiten Leiterplatte vorgesehenen elektrischen Verbinder in Ver- bindung zu bringen ist, durch separate elektrische Verbinder gebildet werden.Accordingly, it is provided that the part of the printed circuit board connector to be connected to the electrical connector provided on one side of the second printed circuit board and the part of the printed circuit board connector which is to be connected to the other side of the second printed circuit board electrical connectors are to be connected by separate electrical connectors.
Eine derartige Aufteilung des Leiterplatten-Steckverbinders in mehrere separate Teileinheiten erweist sich gleich in mehrfacher Hinsicht als vorteilhaft: Einerseits lassen sich dadurch geforderte Toleranzen (beispielsweise die bei SMT- Verfahren geforderte Koplanarität der Anschlüsse) leichter einhalten, andererseits können veränderliche Parameter (beispielsweise unterschiedliche Dicken der auf den Leiterplat- ten-Steckverbinder aufzusteckenden Leiterplatte) mit geringerem Aufwand berücksichtigt werden, und schließlich lassen sich die kleineren Teileinheiten (beispielsweise von Bestük- kungsautomaten) leichter handhaben.Such a division of the printed circuit board connector into several separate sub-units proves to be advantageous in several respects: on the one hand, this makes it easier to comply with the required tolerances (for example, the coplanarity of the connections required in SMT processes), and on the other hand, variable parameters (for example, different thicknesses of the on the printed circuit board connector) can be taken into account with less effort, and finally the smaller subunits (for example of automatic assembly machines) are easier to handle.
Der beanspruchte Leiterplatten-Steckverbinder ist damit auch bei höchsten Qualitäts- und Zuverlässigkeitsanforderungen relativ einfach herstellbar und handhabbar.The claimed circuit board connector is therefore relatively easy to manufacture and handle, even with the highest quality and reliability requirements.

Der betrachtete Leiterplatten-Steckverbinder ist auf der ersten Leiterplatte montiert und dazu ausgelegt, mit auf gegenüberliegenden Seiten der zweiten Leiterplatte vorgesehenen elektrischen Verbindern in Kontakt zu kommen.The circuit board connector under consideration is mounted on the first circuit board and is designed to come into contact with electrical connectors provided on opposite sides of the second circuit board.
Der Zustand, im welchem die erste Leiterplatte und die zweite Leiterplatte über einen solchen Leiterplatten-SteckverbinderThe state in which the first circuit board and the second circuit board have such a circuit board connector
ERZSATZBLATT (REGEL 26) verbunden sind, ist in Figur 1 dargestellt. Dabei sind die erste Leiterplatte mit dem Bezugszeichen 1, der darauf montierte Leiterplatten-Steckverbinder mit dem Bezugszeichen 2, die zweite Leiterplatte mit dem Bezugszeichen 3, und die auf dieser vorgesehenen elektrischen Verbinder mit den Bezugszeichen 4 und 5 bezeichnet.REPLACEMENT BLADE (RULE 26) are connected is shown in Figure 1. The first printed circuit board is designated by the reference number 1, the printed circuit board connector mounted thereon by the reference number 2, the second printed circuit board by the reference number 3, and the electrical connectors provided thereon by the reference numbers 4 and 5.
Der Leiterplatten-Steckverbinder 2 zeichnet sich dadurch aus, daß er aus mehreren separaten Teileinheiten besteht. Bei den separaten Teileinheiten handelt es sich um separate elektrische Verbinder 21 und 22, von welchen einer (der elektrische Verbinder 21) dazu ausgelegt ist, mit dem auf der einen Seite der zweiten Leiterplatte 3 vorgesehenen elektrischen Verbinder (dem elektrischen Verbinder 4) in Kontakt gebracht zu werden, und von welchen der andere (der elektrische Verbinder 22) dazu ausgelegt ist, mit dem auf der anderen Seite der zweiten Leiterplatte 3 vorgesehenen elektrischen Verbinder (dem elektrischen Verbinder 5) in Kontakt gebracht zu werden. Diese elektrischen Verbinder 21 und 22 sind separate Einzel- teile, die unabhängig voneinander auf der ersten Leiterplatte 1 montierbar sind.The circuit board connector 2 is characterized in that it consists of several separate sub-units. The separate sub-units are separate electrical connectors 21 and 22, one of which (the electrical connector 21) is designed to be brought into contact with the electrical connector (the electrical connector 4) provided on one side of the second printed circuit board 3 and the other (the electrical connector 22) is designed to be brought into contact with the electrical connector (the electrical connector 5) provided on the other side of the second circuit board 3. These electrical connectors 21 and 22 are separate individual parts which can be mounted on the first printed circuit board 1 independently of one another.
Die elektrischen Verbinder 21, 22 weisen im betrachteten Beispiel einen identischen Aufbau auf und sind einander um 180° gedreht gegenübergestellt.In the example under consideration, the electrical connectors 21, 22 have an identical structure and are opposed to one another rotated by 180 °.
Einer der elektrischen Verbinder 21, 22, ist in der Figur 2 dargestellt .One of the electrical connectors 21, 22 is shown in FIG. 2.
Die elektrischen Verbinder 21, 22 bestehen aus einem Gehäuse 211, ersten Kontaktelementen 212 zur Verbindung derselben mit der ersten Leiterplatte 1, und zweiten Kontaktelementen 213 zur Verbindung derselben mit den elektrischen Verbindern 4, 5 der zweiten Leiterplatte 3.The electrical connectors 21, 22 consist of a housing 211, first contact elements 212 for connecting them to the first printed circuit board 1, and second contact elements 213 for connecting them to the electrical connectors 4, 5 of the second printed circuit board 3.
Die elektrischen Verbinder 21, 22 sind im betrachteten Beispiel oberflächenmontierbare Verbinder. D.h., die ersten Kon-The electrical connectors 21, 22 are surface-mountable connectors in the example considered. In other words, the first
ERZSATZBLATT (REGEL 26) taktelemente 212 sind dazu ausgelegt, unter Verwendung eines SMT-Verfahrens mit der ersten Leiterplatte verbunden (verlötet) zu werden. Es sei jedoch bereits an dieser Stelle darauf hingewiesen, daß hierauf keine Einschränkung besteht. Die Verbindung zwischen den elektrischen Verbindern 21, 22 und der ersten Leiterplatte kann auch auf beliebige andere Art und Weise erfolgen.REPLACEMENT BLADE (RULE 26) Clock elements 212 are designed to be connected (soldered) to the first printed circuit board using an SMT method. However, it should be pointed out at this point that there is no restriction. The connection between the electrical connectors 21, 22 and the first printed circuit board can also be made in any other way.
Bei den zweiten Kontaktelementen 213 handelt es sich um in zwei nebeneinander liegenden Reihen angeordnete Kontaktmesser. D.h., die elektrischen Verbinder 21, 22 sind zweireihige Messerleisten. Dementsprechend handelt es sich bei den elektrischen Verbindern 4, 5 der zweiten Leiterplatte 3 um zweireihige Federleisten. Auch hierauf besteht jedoch keine Ein- schränkung. Die zweiten Kontaktelemente 213 der elektrischen Verbinder 21, 22 können auch beliebig anders beschaffen und angeordnet sein.The second contact elements 213 are contact blades arranged in two adjacent rows. That is, the electrical connectors 21, 22 are double row male connectors. Accordingly, the electrical connectors 4, 5 of the second printed circuit board 3 are double-row female connectors. However, there is no restriction on this either. The second contact elements 213 of the electrical connectors 21, 22 can also be configured and arranged in any other way.
Die elektrischen Verbinder 21, 22 nach Art der Figur 2 können unabhängig voneinander auf die erste Leiterplatte montiert werden. Insbesondere ist es problemlos möglich, den Abstand zu variieren, in welchem sie parallel zueinander angeordnet werden. Dadurch kann der Leiterplatten-Steckverbinder 2 der ersten Leiterplatte 1 denkbar einfach an die jeweilige Dicke der zweiten Leiterplatte 3 angepaßt werden. Zur Anpassung des Leiterplatten-Steckverbinders 2 an die Dicke der zweiten Leiterplatte 3 müssen nur die Lötpads , an v/elchen die ersten Kontaktelemente 212 der elektrischen Verbinder angelötet werden, entsprechend positioniert v/erden. Wäre der Leiterplat- ten-Steckverbinder wie bisher als eine zusammenhängende (einteilige) Einheit ausgebildet, müßten für verschiedene Dicken der zweiten Leiterplatte 3 jeweils verschiedene Leiterplatten-Steckverbinder bereitgestellt werden.The electrical connectors 21, 22 of the type shown in FIG. 2 can be mounted independently of one another on the first printed circuit board. In particular, it is easily possible to vary the distance at which they are arranged parallel to one another. As a result, the printed circuit board connector 2 of the first printed circuit board 1 can be easily adapted to the respective thickness of the second printed circuit board 3. To adapt the printed circuit board connector 2 to the thickness of the second printed circuit board 3, only the soldering pads, to which the first contact elements 212 of the electrical connectors are soldered, have to be positioned accordingly. If the printed circuit board connector were designed as a coherent (one-piece) unit as before, different printed circuit board connectors would have to be provided for different thicknesses of the second printed circuit board 3.
Die Aufteilung des Leiterplatten-Steckverbinders in separate Teileinheiten erweist sich aber auch in anderer Hinsicht als vorteilhaft .The division of the circuit board connector into separate sub-units also proves to be advantageous in other respects.
ERZSATZBLATT (REGEL 26) Die Teileinheiten, genauer gesagt die elektrischen Verbinder 21, 22 weisen jeweils eine geringere Anzahl von Kontaktelementen (im betrachteten Beispiel jeweils nur halb so viele Kontaktelemente) auf als der Leiterplatten-Steckverbinder 2. Dies erweist sich insbesondere bei den ersten Kontaktelementen 212 als Vorteil. Diese lassen sich (wegen deren vergleichsweise geringen Anzahl) mit verhältnismäßig geringem Aufwand koplanar ausrichten, was bei Verwendung von SMT- Verfahren zur Verbindung mit der ersten Leiterplatte 1 von größter Bedeutung ist; die Anschlüsse von unter Verwendung eines SMT-Verfahrens zu montierenden Bauteilen müssen bekanntlich koplanar ausgerichtet sein.REPLACEMENT BLADE (RULE 26) The sub-units, more precisely the electrical connectors 21, 22 each have a smaller number of contact elements (in the example considered only half as many contact elements) than the circuit board connector 2. This proves to be an advantage in particular with the first contact elements 212. These can (due to their comparatively small number) be aligned coplanar with relatively little effort, which is of great importance when using SMT methods for connection to the first printed circuit board 1; As is known, the connections of components to be assembled using an SMT process must be coplanar.
Abgesehen davon lassen sich die separaten Teileinheiten derApart from that, the separate subunits of the
Leiterplatten-Steckverbinders wegen deren vergleichsweise geringen Größe (beispielsweise von Bestückungsautomaten) erheblich einfacher handhaben als ein als eine zusammenhängende Einheit ausgebildeter Leiterplatten-Steckverbinder.Because of their comparatively small size (for example of automatic assembly machines), circuit board connectors are much easier to handle than a circuit board connector designed as a coherent unit.
Im betrachteten Beispiel handelt es sich bei den Teileinheiten (den elektrischen Verbindern 21, 22) des Leiterplatten- Steckverbinders um identisch ausgebildete Komponenten. Dies erweist sich zwar als besonders vorteilhaft, weil dann nur eine minimale Anzahl verschiedenartiger Teile hergestellt und montiert werden muß, ist aber nicht zwingend erforderlich. Bei den elektrischen Verbindern 21, 22 kann es sich auch um verschiedene elektrische Verbinder handeln. Beispielsweise kann der erste elektrische Verbinder 21 eine zweireihige Mes- serleiste sein, und der zweite elektrische Verbinder eine vierreihige Messerleiste.In the example considered, the subunits (the electrical connectors 21, 22) of the printed circuit board connector are identical components. This proves to be particularly advantageous because then only a minimal number of different types of parts have to be manufactured and assembled, but is not absolutely necessary. The electrical connectors 21, 22 can also be various electrical connectors. For example, the first electrical connector 21 can be a two-row knife bar and the second electrical connector can be a four-row knife bar.
Der beschriebene Leiterplatten-Steckverbinder ist unabhängig von den Einzelheiten der praktischen Realisierung auch bei höchsten Qualitäts- und Zuverlässigkeitsanforderungen relativ einfach herstellbar und handhabbar.The printed circuit board connector described is relatively easy to manufacture and handle, regardless of the details of the practical implementation, even with the highest quality and reliability requirements.
