Description

Die vorliegende Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device according to the preamble of patent claim 1.

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 known in a variety of embodiments and need no further description. They are characterized by the fact that they are alone by pressing the pins in the associated Einpreßbohrungen on the circuit board, so quickly and easily electrically and mechanically connected to the circuit board. On the other hand, such electrical connectors can not be made as small as possible with other mountable on the circuit board connectors. This is mainly due to the size and the mutual distances of the press-fit holes on the circuit board: a reduction of the press-in holes are opposed to manufacturing problems (small holes can be galvanized poorly at great depth), and a reduction in the mutual distances of the injection holes are the resulting reduced mechanical strength the circuit board and the need to lead in the spaces between the press-in holes electrical traces, contrary.

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. In US 5 240 422 A ist ein elektrischer Verbinder beschrieben, bei dem Kontaktabschnitte in entsprechende Anschlussabschnitte übergehen, über die der Verbinder in Bohrungen einer Leiterplatte befestigt wird. Hierbei sind die Kontaktabschnitte über einen abgebogenen Mittelteil jeweils mit den Anschlussabschnitten verbunden. Dadurch sind die Kontaktabschnitte geometrisch unterschiedlich zu den Anschlussabschnitten angeordnet. 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.Electrical connectors of this type and thus also the printed circuit boards on which they are mounted, as well as the devices containing such printed circuit boards are thereby limited miniaturized. This is a considerable disadvantage in view of the endeavor to make objects of all kinds smaller and smaller, despite increasing efficiency. US 5 240 422 A discloses an electrical connector in which contact portions transition into corresponding terminal portions via which the connector is mounted in holes of a printed circuit board. Here, the contact portions are connected via a bent middle part in each case with the connection portions. As a result, the contact portions are arranged geometrically different from the connection sections. The present invention is therefore based on the object, the electrical connector according to the preamble of claim 1 such that it is not hindering further miniaturization in the way.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 beanspruchten Merkmale gelöst.This object is achieved by the features claimed in claim 1.

Insbesondere ist vorgesehen, daß die Kontaktelemente anders angeordnet und/oder anders voneinander beabstandet sind als die Anschlußstifte.In particular, it is provided that the contact elements are arranged differently and / or spaced from each other differently than the 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.As a result, the contact elements of the electrical connector and its intended for mounting on the circuit board pins (and thus also the pins associated with Einpreßbohrungen on the circuit board) can be optimized independently.

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.
In the press-in holes, this opens up, inter alia, the possibility
  • that they can be arranged relative to one another (can be distributed and / or grouped) such that the printed circuit board is optimized with respect to their shape and / or size and / or with respect to other needs, and
  • on the other hand, they can be made so large and can be placed so far apart that they can be produced without problems and printed conductors can be passed between them.

Unabhängig davon werden die Kontaktelemente beispielsweise so ausgebildet, angeordnet (umgeordnet) und/oder zusammengeschoben, 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.Regardless, the contact elements are for example so formed, arranged (rearranged) and / or pushed together that they allow the connection of miniaturized electrical connector, whereby the space on, above, below and / or next to the circuit board and / or within of a device containing such a circuit board is to be reserved for the electrical connectors to be contacted, 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.Due to the inventive design of the electrical connector, this allows a significant reduction of the printed circuit boards provided with this and the devices containing them.

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

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 is designated by the reference numeral 1 in the figures. It is designed to be mounted on the surface of a circuit board using the press-fit technique. In the state mounted on the circuit board, it serves to connect this circuit board with another, mounted on it circuit board; However, it may additionally or alternatively be designed for connecting a cable or other devices.

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 a connector in the example considered. However, the invention can also be used in other types of electrical connectors, for example in Andruckverbindern for contacting surface contacts, etc. The electrical connector can also be designed, among other things, as a zero-force connector or floating connector 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.Referring particularly to FIGS. 1 and 3, the electrical connector 1 includes a housing 11, a plurality of contact members 12, and a plurality of (circuit board) terminal 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 terminal pins 13 are adapted to be pressed into associated Einpreßbohrungen 21 of a printed circuit board 2. The terminal pins 13 and / or the Einpreßbohrungen 21 are adapted to each other so that they jam when pressed into each other and thereby a solid mechanical and electrical (the Einpreßbohrungen are coated with electrically conductive material) enter into connection with the circuit board 2.

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 electrical contact with the contact elements of an electrical connector connected to the electrical connector 1. This (not shown in the figures) second electrical connector is mounted in the example considered on a second circuit board 3, the edge portion as shown in Figure 3 can be inserted into a formed in the housing 11 of the electrical connector 1 recess 111.

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.Each contact element 12 is assigned a pin 13. The mutually associated contact elements 12 and pins 13 are each formed as a coherent unit, within which the respective contact element and the associated pin merge into each other. These contact element pin units are for example formed by stamped sheet metal elongated elements, which, as is apparent in particular from Figures 2 and 3, are formed at one end as a contact element and at its other end as a 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.The contact elements 12 are, however, arranged differently and spaced differently from each other as the terminal pins 13. While the contact elements are arranged in a matrix with n rows and m columns and occupy only a part of the connector base, the pins are in a matrix with 2n rows and m / 2 columns and distributed over the entire connector footprint.

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 aforementioned rearrangement described in greater detail below represents a particularly advantageous variant, particularly with regard to the production of the electrical connector, there is, moreover, a large number of likewise advantageous further rearrangement possibilities.

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 previously at least partially a change of direction having (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 embodiment of the contact element pin unit for achieving the above-mentioned rearrangement is illustrated in FIG.

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 portion of the printed circuit board 2 comprising the press-in bores 21 and eight contactor pin units of the electrical connector 1. The eight contact elements 12 represent two adjacent columns of n (n = 4) rows and m columns of contact elements matrix. and the eight pins 13 represent one column of the 2n rows and m / 2 column pin matrix. It is
  • the terminal pin located on the left outside according to the illustration in FIG. 2 in the terminal pin column is assigned to the contact element lying on the left outside as shown in FIG. 2 in the rear contact element column,
  • 2 as shown in FIG. 2 in the terminal pin column at the second position from the left-lying terminal pin assigned to the contact element according to the illustration in FIG. 2 in the front contact element column on the left outside,
  • 2 as shown in FIG. 2 in the terminal pin column at the third position from the left lying terminal pin according to the illustration in FIG. 2 in the rear contact element column in the second position from the left lying contact element,
  • 2 as shown in FIG. 2 in the terminal pin column at the fourth position from the left-lying terminal pin assigned to the contact element according to the illustration in FIG. 2 in the front contact element column second from the left,
  • 2 as shown in FIG. 2 in the terminal pin column at the fifth position from the left-lying terminal pin assigned to the contact element according to the illustration in FIG. 2 in the rear contact element column in third place from the left,
  • 2 as shown in FIG. 2 in the terminal pin column at the sixth position from the left-lying terminal pin assigned to the contact element according to the illustration in FIG. 2 in the front contact element column in third place from the left,
  • in accordance with the illustration in Figure 2 in the pin-column at the seventh place from the left-lying terminal pin assigned as shown in the figure 2 in the rear contact elements column right outer contact element, and
  • the according to the illustration in Figure 2 in the pin-column right outer pin lying assigned to the according to the illustration in Figure 2 in the front contact elements column right outer contact element.

Die den zwei Kontaktelemente-Spalten zugeordnete Anschlußstifte-Spalte verläuft in der Draufsicht mittig zwischen den Kontaktelemente-Spalten.The terminal column column associated with the two contact element columns extends centrally in the plan view between the contact element 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 have in the example considered on the local course shown in Figure 2. That is, unlike the contactor pin units of conventional electrical connectors of the type described, they no longer have a substantially rectilinear course, but change direction several times in their middle part between the contact element and the terminal pin.

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 bent, curved and / or kinked center portions of the contactor pin units preferably extend 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 (cast around by this) and form an inseparable unit with this. Only the substantially straight parts of the contact element pin unit, ie in particular the contact elements 12 and the pins 13 protrude freely upwards or downwards. As a result, the risk that the curved, curved and / or kinking extending middle parts of the contact element pin unit units in the Assembly of the electrical connector to be applied to the PCB pressure applied and not be damaged by this (deformed), 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 units, the contact elements and the pins may have different arrangements and / or mutual distances.

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 design freedom has been exploited to the effect that the contact elements are arranged in half as many rows, but twice as many columns as the pins, wherein adjacent contact elements rows have the same distance as adjacent terminal rows, adjacent contact elements columns, however, only half the distance that adjacent pin columns have 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.Assigning the contact elements in a uniform grid, so that adjacent contact elements of a column are just as far apart from each other as adjacent contact elements columns (for example, each 2.5 mm), the terminal pin columns can be relatively far apart. In this relatively wide gap between adjacent pin columns, more precisely in the interstices of the associated press-in holes of the printed circuit board conductor tracks can be performed.

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.In the example under consideration, the contact element columns and the connector pins columns, which are considerably longer than the latter (twice as long), are centered relative to one another with respect to their longitudinal extent; 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 pin matrix, the contact elements are distributed over only a portion of the base of the electrical connector. The not occupied by the contact elements part of the base of the electrical connector can be used elsewhere. In the example considered, the electrical connector is designed for insertion of the printed circuit board to which contact is to be made via the electrical connector.

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 dense arrangement of the contact elements also makes it possible that the electrical connector to be brought into contact with the electrical connector can be made small, whereby the electrical connectors to be contacted take up little space overall and can be brought into contact with each other in a small space.

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.Thereby, the space to be reserved on, above, below and / or next to the circuit board and / or within a device containing such a circuit board for the electrical connectors to be contacted can be minimized.
