Description

Die vorliegende Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1, d.h. einen elektrischen Verbinder zur Montage auf einer Leiterplatte, wobei die Kontaktelemente des elektrischen Verbinders in Anschlußstifte zum Einpressen in zugeordnete Einpreßbohrungen der Leiterplatte übergehen.The present invention relates to a device according to the Preamble of claim 1, i.e. an electric one Connector for mounting on a printed circuit board, the Contact elements of the electrical connector in connection pins for pressing into assigned press-in holes in the circuit board pass over.

Elektrische Verbinder dieser Art sind in einer Vielzahl von Ausführungsformen bekannt und bedürfen keiner näheren Beschreibung. Sie zeichnen sich dadurch aus, daß sie allein durch das Einpressen der Anschlußstifte derselben in die zugeordneten Einpreßbohrungen auf der Leiterplatte, also schnell und einfach elektrisch und mechanisch mit der Leiterplatte verbindbar sind. Andererseits können solche elektrischen Verbinder nicht so klein ausgebildet werden wie es bei anders auf der Leiterplatte montierbaren Verbindern möglich ist. Verantwortlich hierfür sind vor allem die Größe und die gegenseitigen Abstände der Einpreßbohrungen auf der Leiterplatte: einer Verkleinerung der Einpreßbohrungen stehen Herstellungsprobleme entgegen (kleine Löcher können bei großer Tiefe schlecht galvanisiert werden), und einer Verringerung der gegenseitigen Abstände der Einpreßbohrungen stehen die dadurch verringerte mechanische Festigkeit der Leiterplatte und die Notwendigkeit, in den Zwischenräumen zwischen den Einpreßbohrungen elektrische Leiterbahnen zu führen, entgegen.Electrical connectors of this type are available in a variety of Embodiments are known and require no further description. They are characterized by the fact that they are alone by pressing the pins into the associated pins Press-in holes on the circuit board, so quick and easy electrical and mechanical with the circuit board are connectable. On the other hand, such electrical Connectors are not designed to be as small as in otherwise possible to mount connectors on the circuit board is. The size and size are responsible for this mutual spacing of the press-in holes on the circuit board: a reduction in the press-in holes Manufacturing problems counter (small holes can large depth are poorly galvanized), and a reduction the mutual spacing of the press-in holes the resulting reduced mechanical strength Printed circuit board and the need in the spaces electrical conductor tracks between the press-in holes lead, counter.

Elektrische Verbinder dieser Art und damit auch die Leiterplatten, auf denen diese montiert sind, sowie die solche Leiterplatten enthaltenden Geräte sind dadurch nur begrenzt miniatursierbar. Dies ist in Anbetracht des Bestrebens, Gegenstände aller Art trotz steigender Leistungsfähigkeit immer kleiner zu machen, ein nicht unerheblicher Nachteil. Electrical connectors of this type and thus also the printed circuit boards, on which these are mounted, as well as those Devices containing printed circuit boards are therefore only limited miniaturizable. This is in view of the desire Objects of all kinds despite increasing performance making smaller and smaller, a not inconsiderable disadvantage.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, den elektrischen Verbinder gemäß dem Oberbegriff des Patentanspruchs 1 derart weiterzubilden, daß dieser einer weiteren Miniaturisierung nicht hindernd im Wege steht.The present invention is therefore based on the object the electrical connector according to the preamble of the claim 1 in such a way that this one another Miniaturization does not stand in the way.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 beanspruchten Merkmale gelöst.This object is achieved by the characterizing Part of claim 1 claimed features solved.

Demnach ist vorgesehen, daß die Kontaktelemente anders angeordnet und/oder anders voneinander beabstandet sind als die Anschlußstifte.Accordingly, it is provided that the contact elements are arranged differently and / or are spaced apart from one another differently than that Pins.

Dadurch können die Kontaktelemente des elektrischen Verbinders und dessen zur Montage auf der Leiterplatte vorgesehenen Anschlußstifte (und damit auch die den Anschlußstiften zugeordneten Einpreßbohrungen auf der Leiterplatte) unabhängig voneinander optimiert werden.This allows the contact elements of the electrical connector and its intended for mounting on the circuit board Connection pins (and thus also those assigned to the connection pins Press-in holes on the PCB) independently be optimized from each other.

Bei den Einpreßbohrungen eröffnet dies unter anderem die Möglichkeit,

  • daß sie zum einen relativ zueinander so anordenbar (so verteilbar und/oder gruppierbar) sind, daß die Leiterplatte hinsichtlich deren Form und/oder Größe und/oder hinsichtlich sonstiger Bedürfnisse optimiert ist, und
  • daß sie zum anderen so groß ausbildbar und so weit voneinander beabstandet platzierbar sind, daß sie problemlos herstellbar sind und Leiterbahnen zwischen diesen hindurch geführt werden können.
With the press-in holes, this opens up the possibility, among other things,
  • that on the one hand they can be arranged relative to each other (so distributable and / or groupable) that the circuit board is optimized with regard to its shape and / or size and / or with regard to other needs, and
  • that on the other hand they can be designed so large and placed so far apart that they can be produced without problems and conductor tracks can be passed between them.

Unabhängig davon können die Kontaktelemente beispielsweise so ausgebildet, angeordnet (umgeordnet) und/oder zusammengeschoben werden, daß sie den Anschluß miniaturisierter elektrischer Verbinder ermöglichen, wodurch der Platz, der auf, über, unter und/oder neben der Leiterplatte und/oder innerhalb eines eine solche Leiterplatte enthaltenden Gerätes für die in Kontakt zu bringenden elektrischen Verbinder zu reservieren ist, auf ein Minimum reduziert werden kann.Irrespective of this, the contact elements can be so, for example trained, arranged (rearranged) and / or pushed together be that they are connecting miniaturized electrical Enable connectors, which allows the space that is on, above, below and / or next to the circuit board and / or inside of a device containing such a circuit board for reserve the electrical connectors to be contacted is can be reduced to a minimum.

Durch die erfindungsgemäße Ausbildung des elektrischen Verbinders erlaubt dieser eine erhebliche Verkleinerung der mit diesem versehenen Leiterplatten und der dieselben enthaltenden Geräte.The inventive design of the electrical connector this allows a significant reduction in the size of the this provided printed circuit boards and those containing them Equipment.

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of subclaims.

Der im folgenden näher beschriebene elektrische Verbinder ist in den Figuren mit dem Bezugszeichen 1 bezeichnet. Er ist dazu ausgelegt, unter Verwendung der Einpreßtechnik auf der Oberfläche einer Leiterplatte montiert zu werden. Im auf der Leiterplatte montierten Zustand dient er dazu, diese Leiterplatte mit einer anderen, darauf aufgesteckten Leiterplatte zu verbinden; er kann jedoch zusätzlich oder alternativ auch zum Anschluß eines Kabels oder sonstiger Einrichtungen ausgelegt sein. The electrical connector described in more detail below in the figures with the reference numeral 1. He is designed using the press-fit technique on the Surface of a printed circuit board. Im on the Circuit board assembled state it serves this circuit board with another circuit board attached to it connect to; however, it can additionally or alternatively also designed for connecting a cable or other devices be.

Der elektrische Verbinder 1 ist im betrachteten Beispiel ein Steckverbinder. Die Erfindung läßt sich jedoch auch bei andersartigen elektrischen Verbindern, beispielsweise bei Andruckverbindern zur Kontaktierung von Oberflächenkontakten etc. anwenden. Der elektrische Verbinder kann unter anderem auch als Nullkraftsteckverbinder oder schwimmender Verbinder ausgebildet sein oder sonstige besonderen Bauformen aufweisen.The electrical connector 1 is in the example considered Connectors. However, the invention can also be used different types of electrical connectors, for example Pressure connectors for contacting surface contacts etc. apply. The electrical connector can, among other things also as zero force connector or floating connector be trained or have other special designs.

Wie insbesondere aus den Figuren 1 und 3 ersichtlich ist, umfaßt der elektrische Verbinder 1 ein Gehäuse 11, eine Vielzahl von Kontaktelementen 12 und eine Vielzahl von (Leiterplatten-)Anschlußstiften 13.As can be seen in particular from FIGS. 1 and 3, the electrical connector 1 comprises a housing 11, a plurality of contact elements 12 and a variety of (PCB) connector pins 13.

Die Anschlußstifte 13 sind dazu ausgelegt, in zugeordnete Einpreßbohrungen 21 einer Leiterplatte 2 eingepreßt zu werden. Die Anschlußstifte 13 und/oder die Einpreßbohrungen 21 sind so aneinander angepaßt, daß sie sich beim Ineinanderpressen verklemmen und dadurch eine feste mechanische und elektrische (die Einpreßbohrungen sind mit elektrisch leitendem Material beschichtet) Verbindung mit der Leiterplatte 2 eingehen.The pins 13 are designed to be assigned in Press-in holes 21 of a circuit board 2 to be pressed. The connecting pins 13 and / or the press-in holes 21 are matched to each other so that they are pressed together jam and thereby a firm mechanical and electrical (the press-in holes are electrically conductive Material coated) Connection to the circuit board 2 come in.

Die Kontaktelemente 12 dienen dazu, einen elektrischen Kontakt zu den Kontaktelementen eines mit dem elektrischen Verbinder 1 in Verbindung gebrachten elektrischen Verbinders herzustellen. Dieser (in den Figuren nicht gezeigte) zweite elektrische Verbinder ist im betrachteten Beispiel auf einer zweiten Leiterplatte 3 montiert, deren Randabschnitt wie in der Figur 3 gezeigt in eine im Gehäuse 11 des elektrischen Verbinders 1 ausgebildete Aussparung 111 steckbar ist.The contact elements 12 serve to make an electrical contact to the contact elements one with the electrical connector 1 related electrical connector to manufacture. This second one (not shown in the figures) electrical connector is in the example considered on a second circuit board 3 mounted, the edge portion as in 3 shown in a in the housing 11 of the electrical Connector 1 formed recess 111 is pluggable.

Jedem Kontaktelement 12 ist ein Anschlußstift 13 zugeordnet. Die einander zugeordneten Kontaktelemente 12 und Anschlußstifte 13 sind jeweils als eine zusammenhängende Einheit ausgebildet, innerhalb welcher das jeweilige Kontaktelement und der zugeordnete Anschlußstift ineinander übergehen. Diese Kontaktelement-Anschlußstift-Einheiten sind beispielsweise durch Blechstanzteile gebildete längliche Elemente, die, wie insbesondere aus den Figuren 2 und 3 ersichtlich ist, an ihrem einen Ende als Kontaktelement und an ihrem anderen Ende als Anschlußstift ausgebildet sind.A pin 13 is assigned to each contact element 12. The mutually associated contact elements 12 and pins 13 are each formed as a coherent unit, within which the respective contact element and the assigned pin merge. This Contact element pin units are, for example elongated elements formed by sheet metal stampings, which, like can be seen in particular from FIGS. 2 and 3 at one end as a contact element and at the other end are designed as a connecting pin.

Die Kontaktelemente 12 sind dabei jedoch anders angeordnet und anders voneinander beabstandet als die Anschlußstifte 13. Während die Kontaktelemente in einer Matrix mit n Reihen und m Spalten angeordnet sind und nur einen Teil der Verbindergrundfläche belegen, sind die Anschlußstifte in einer Matrix mit 2n Reihen und m/2 Spalten angeordnet und über die gesamte Verbindergrundfläche verteilt.However, the contact elements 12 are arranged differently and spaced differently from each other than the connecting pins 13. While the contact elements in a matrix with n rows and m columns are arranged and only part of the connector base the pins are in a matrix arranged with 2n rows and m / 2 columns and over the whole Distributed connector area.

Zwar stellt die erwähnte und nachfolgend noch näher beschriebenen Umordnung eine vor allem hinsichtlich der Herstellung des elektrischen Verbinders besonders vorteilhafte Variante dar, doch existiert darüber hinaus eine große Vielzahl ebenfalls vorteilhafter weiterer Umordnungs-Möglichkeiten.Although the mentioned and described in more detail below Rearranging one especially with regard to manufacturing the particularly advantageous variant of the electrical connector , but there is also a large variety advantageous further reordering options.

Die Kontaktelement-Anschlußstift-Einheiten haben anders als bisher zumindest teilweise einen Richtungswechsel aufweisenden (gebogenen, gekrümmten und/oder abknickenden) Verlauf.The contact element pin units have different than so far at least partially showing a change of direction (curved, curved and / or kinking) course.

Eine zur Erzielung der vorstehend erwähnten Umordnung geeignete Ausbildung der Kontaktelement-Anschlußstift-Einheiten ist in Figur 2 veranschaulicht.A suitable one to achieve the rearrangement mentioned above Formation of the contact element pin units is illustrated in Figure 2.

Die Figur 2 zeigt den die Einpreßbohrungen 21 umfassenden Abschnitt der Leiterplatte 2 und acht Kontaktelement-Anschlußstift-Einheiten des elektrischen Verbinders 1. Die acht Kontaktelemente 12 repräsentieren zwei nebeneinander liegende Spalten der n (n=4) Reihen und m Spalten umfassenden Kontaktelemente-Matrix, und die acht Anschlußstifte 13 repräsentieren eine Spalte der 2n Reihen und m/2 Spalten umfassenden Anschlußstifte-Matrix.

FIG. 2 shows the section of the printed circuit board 2 comprising the press-in bores 21 and eight contact element connector pin units of the electrical connector 1. The eight contact elements 12 represent two adjacent columns of the n (n = 4) rows and contact element matrix comprising m columns, and the eight pins 13 represent a column of the 2n row and m / 2 column pin matrix.

  • the connecting pin lying on the right outside in the connection pin column as shown in FIG. 2 is assigned to the contact element lying on the right outside in the front contact element column as shown in FIG. 2.

Die den zwei Kontaktelemente-Spalten zugeordnete Anschlußstifte-Spalte verläuft in der Draufsicht mittig zwischen den Kontaktelemente-Spalten.The pin column associated with the two contact element columns runs in the top view in the middle between the Contact elements columns.

Die Kontaktelement-Anschlußstift-Einheiten weisen im betrachteten Beispiel den in der Figur 2 gezeigten örtlichen Verlauf auf. D.h., sie haben anders als die Kontaktelement-Anschlußstift-Einheiten herkömmlicher elektrischer Verbinder der beschriebenen Art keinen im wesentlichen geradlinigen Verlauf mehr, sondern wechseln in ihrem Mittelteil zwischen dem Kontaktelement und dem Anschlußstift mehrfach die Richtung.The contact element pin units point in the considered Example of the local course shown in FIG. 2 on. That is, they have different than the contact element pin units conventional electrical connector of the described Kind of no essentially straight line more, but alternate in their middle section between the Contact element and the connector pin several times the direction.

Die gebogen, gekrümmt und/oder abknickend verlaufenden Mittelteile der Kontaktelement-Anschlußstift-Einheiten verlaufen vorzugsweise im wesentlichen vollständig innerhalb und/oder entlang massiv ausgebildeter Abschnitte des Gehäuses 11 des elektrischen Verbinders; sie sind zumindest teilweise in den betreffenden Gehäuseabschnitt eingebettet (von diesem umgossen) und bilden mit diesem eine untrennbare Einheit. Nur die im wesentlichen gerade verlaufenden Teile der Kontaktelement-Anschlußstift-Einheiten, d.h. insbesondere die Kontaktelemente 12 und die Anschlußstifte 13 ragen frei nach oben bzw. unten heraus. Dadurch ist die Gefahr, daß die gebogen, gekrümmt und/oder abknickend verlaufenden Mittelteile der Kontaktelement-Anschlußstift-Einheiten dem bei der Montage des elektrischen Verbinders auf die Leiterplatte aufzubringenden Einpreßdruck nicht standhalten und durch diesen beschädigt (deformiert) werden, auf ein Minimum reduziert.The curved, curved and / or kinking Middle parts of the contact element pin units run preferably substantially entirely within and / or along solid sections of the housing 11 of the electrical connector; they are at least partially embedded in the relevant housing section (from this cast) and form an inseparable unit with it. Just the essentially straight parts of the contact element pin unit, i.e. especially the Contact elements 12 and the pins 13 protrude freely out at the top or bottom. This creates the danger that the bent curved and / or kinking middle parts the contact element pin units at the Assembly of the electrical connector to be attached to the circuit board Press-in pressure cannot withstand and through this damaged (deformed) are reduced to a minimum.

Durch die besondere Ausbildung der Kontaktelement-Anschlußstift-Einheiten können die Kontaktelemente und die Anschlußstifte verschiedene Anordnungen und/oder gegenseitige Abstände aufweisen.Due to the special design of the contact element pin unit can the contact elements and the connecting pins different arrangements and / or mutual distances exhibit.

Vorliegend wurde diese Gestaltungsfreiheit dahingehend ausgenutzt, daß die Kontaktelemente in halb so vielen Reihen, aber doppelt so vielen Spalten wie die Anschlußstifte angeordnet sind, wobei benachbarte Kontaktelemente-Reihen den selben Abstand aufweisen wie benachbarte Anschlußstifte-Reihen, benachbarte Kontaktelemente-Spalten jedoch nur die Hälfte des Abstandes aufweisen, den benachbarte Anschlußstifte-Spalten voneinander haben.In the present case, this freedom of design was exploited to the extent that that the contact elements in half as many rows, but arranged twice as many columns as the pins are, with adjacent rows of contact elements have the same distance as adjacent rows of pins, neighboring contact element columns, however, only those Have half the distance between the adjacent pin columns from each other.

Ordnet man die Kontaktelemente in einem gleichmäßigen Raster an, so daß benachbarte Kontaktelemente einer Spalte genauso weit voneinander entfernt sind wie benachbarte Kontaktelemente-Spalten (beispielsweise jeweils 2,5 mm), so können die Anschlußstifte-Spalten relativ weit voneinander entfernt sein. In diesem relativ breiten Zwischenraum zwischen benachbarten Anschlußstifte-Spalten, genauer gesagt in den Zwischenräumen der zugeordneten Einpreßbohrungen der Leiterplatte können Leiterbahnen geführt werden.If you arrange the contact elements in a uniform grid so that neighboring contact elements of a column are the same are far apart from each other like neighboring contact element columns (for example 2.5 mm each), so the pin columns are relatively far apart be. In this relatively wide space between neighboring ones Pin columns, more precisely in the Gaps between the assigned press-in holes of the circuit board tracks can be routed.

Die Kontaktelemente-Spalten und die gegenüber diesen erheblich längeren (doppelt so langen) Anschlußstifte-Spalten sind im betrachteten Beispiel bezüglich ihrer Längenausdehnung relativ zueinander zentriert angeordnet; sie können jedoch auch beliebige andere Relativlagen aufweisen.The contact element columns and those compared to them considerably longer (twice as long) pin columns in the example considered with regard to their linear expansion centered relative to each other; however, they can also have any other relative positions.

Unabhängig von der Relativlage der Kontaktelemente-Matrix und der Anschlußstifte-Matrix sind die Kontaktelemente nur über einen Teil der Grundfläche des elektrischen Verbinders verteilt. Der nicht von den Kontaktelementen belegte Teil der Grundfläche des elektrischen Verbinders kann anderweitig genutzt werden. Im betrachteten Beispiel ist der elektrische Verbinder zum Einstecken der Leiterplatte ausgelegt, zu welcher über den elektrischen Verbinder Kontakt hergestellt werden soll.Regardless of the relative position of the contact element matrix and the contact pin matrix, the contact elements are only over distributed part of the base of the electrical connector. The part of the not occupied by the contact elements Base of the electrical connector can be used for other purposes become. In the example considered is the electrical one Connector designed to insert the circuit board to which be made via the electrical connector should.

Die dichte Anordnung der Kontaktelemente ermöglicht es darüber hinaus, daß der mit dem elektrischen Verbinder in Kontakt zu bringenden elektrische Verbinder klein ausgebildet sein kann, wodurch die in Kontakt zu bringenden elektrischen Verbinder insgesamt wenig Platz beanspruchen und auch auf engem Raum miteinander in Kontakt bringbar sind.The tight arrangement of the contact elements makes it possible moreover, that with the electrical connector in Electrical connectors to be brought into contact are small can be, whereby the electrical to be brought into contact All in all, connectors take up little space and also in tight spaces Space can be brought into contact with each other.

Dadurch kann der Platz, der auf, über, unter und/oder neben der Leiterplatte und/oder innerhalb eines eine solche Leiterplatte enthaltenden Gerätes für die in Kontakt zu bringenden elektrischen Verbinder zu reservieren ist, auf ein Minimum reduziert werden.This allows the space that is on, above, below and / or next to the circuit board and / or within such a circuit board containing device for those to be brought into contact Reserve electrical connectors to a minimum be reduced.
