Abstract

An electrical connector pair has a first electrical connector and a second electrical connector which can be connected thereto. The first electrical connector has a multiplicity of contacting elements which can be brought into contact with contacting elements of the second electrical connector through relative movement of the two connectors in a contacting direction. The contacting elements are arranged in one or more rows extending in a row-alignment direction. The contacting elements of the electrical connectors of the pair can be brought into contact with a given amount of play in a transverse direction orthogonal to the contacting direction and to the row-alignment direction. The play is effective on either one or both sides and permits a mutual offset of the electrical connectors and is greater by a multiple than a play provided in the row-alignment direction.

Description

Die vorliegende Erfindung betrifft ein elektrisches Verbinderpaar gemäß dem Oberbegriff des Patentanspruchs 1, d.h. ein elektrisches Verbinderpaar bestehend aus einem ersten elektrischen Verbinder und einem mit demselben verbindbaren zweiten elektrischen Verbinder, wobei der erste elektrische Verbinder eine Vielzahl von Kontaktierungselementen aufweist, welche mit Kontaktierungselementen des zweiten elektrischen Verbinders unter relativer Bewegung in eine Kontaktierungsrichtung in Kontakt bringbar sind, und welche in mindestens einer, sich in einer Reihenausrichtungsrichtung erstreckenden Reihe angeordnet sind.The present invention relates to an electrical connector pair according to the preamble of claim 1, i.e. a electrical connector pair consisting of a first electrical Connector and a second connectable to the same electrical connector, the first electrical connector has a large number of contacting elements, which with contacting elements of the second electrical Connector with relative movement in a contact direction can be brought into contact, and which in at least one extending in a row alignment direction Row are arranged.

Will man einen zur Montage auf einer elektrischen Leiterplatte vorgesehenen ersten elektrischen Verbinder mit der elektrischen Leiterplatte durch Oberflächenmontage, d.h. nach einem SMT-Verfahren elektrisch und mechanisch verbinden (verlöten), so ist dieser, da die im auf der Leiterplatte montierten Zustand des elektrischen Verbinders neben demselben vorzusehenden Verbindungs- bzw. Lötstellen aus praktischen Gründen in ihrer Anzahl begrenzt sind, vorteilhafter Weise derart ausgebildet, daß dessen Kontaktierungselemente und die zugeordneten Anschlußvorrichtungen (in der Regel Lötstiele, die gegebenenfalls abgewinkelt sind) auf beide Seiten der Leiterplatte verteilt und mit den jeweiligen Oberflächen dieser Leiterplattenseiten verbunden werden.Do you want one for mounting on an electrical circuit board provided first electrical connector with the electrical circuit board by surface mounting, i.e. after an electrical and mechanical connection using an SMT process (solder), this is because the im on the circuit board assembled state of the electrical connector next to the same provided connections or soldering points from practical Reasons are limited in number, more advantageous Formed such that its contacting elements and the associated connection devices (usually soldering sticks, which may be angled) on both sides the circuit board distributed and with the respective surfaces of these PCB sides are connected.

Ein derartiger elektrischer Verbinder ist aus der EP 0 278 868 B1 bekannt.Such an electrical connector is known from EP 0 278 868 B1 known.

Der in dieser Druckschrift beschriebene elektrische Verbinder weist an seiner Rückseite eine zentrale, nutenartige Aussparung auf, welche es ermöglicht, den elektrischen Verbinder über den Randabschnitt einer elektrischen Leiterplatte zu schieben und auf diese Weise dafür zu sorgen, daß dessen Kontaktierungselemente und die zugeordneten Anschlußvorrichtungen auf beide Seiten der elektrischen Leiterplatte verteilt und damit in einer vergleichsweise großen Gesamtanzahl vorsehbar sind.The electrical connector described in this document has a central, groove-like recess on the back on which enables the electrical connector over the edge portion of an electrical circuit board push and in this way to ensure that its contacting elements and the associated connection devices distributed on both sides of the electrical circuit board and therefore predictable in a comparatively large total number are.

Da die erwähnte Aussparung im elektrischen Verbinder vorteilhafterweise an die Dicke der Leiterplatte angepaßt ist, besteht hier jedoch der Nachteil, daß unterschiedlich dicke Leiterplatten die Verwendung unterschiedlich ausgebildeter elektrischer Verbinder erfordern. Darüber hinaus ist das Aufstecken eines Elements auf den Rand einer Leiterplatte ein Vorgang, welcher von herkömmlichen Bestückungsmaschinen für die Oberflächenmontage nicht automatisch durchführbar ist.Because the mentioned recess in the electrical connector advantageously is adapted to the thickness of the circuit board here however the disadvantage that different thicknesses Printed circuit boards using differently trained electrical connector. In addition, the plugging on of an element on the edge of a circuit board Process, which of conventional placement machines for surface mounting cannot be carried out automatically.

Zur Lösung dieses Problems könnte, wie aus der EP 0 360 625 A2 bekannt ist, vorgesehen werden, den elektrischen Verbinder nicht einteilig, sondern zweiteilig auszubilden, wobei das eine Verbinderelement auf der einen Seite der Leiterplatte, und das andere Verbinderelement unabhängig davon auf der zweiten Seite der Leiterplatte anordenbar ist.To solve this problem, as from EP 0 360 625 A2 is known to be provided the electrical connector not to form in one part, but in two parts, the a connector element on one side of the circuit board, and the other connector element regardless of that on the second side of the circuit board can be arranged.

In diesem Fall ist der elektrische Verbinder jedoch relativ empfindlich gegen mechanische Belastungen. Sind nämlich die Positionierung, die Ausrichtung und/oder die Abmessungen des ersten elektrischen Verbinders und/oder des damit in Kontakt zu bringenden bzw. stehenden zweiten elektrischen Verbinders beim Inkontaktbringen oder im Kontaktzustand derselben nicht genau aufeinander abgestimmt, können auf den ersten elektrischen Verbinder Kräfte wirken, die aufgrund der nur relativ schwach belastbaren SMT-Verbindungsstellen ein Ablösen oder Abreißen desselben von der Leiterplatte bewirken oder wenigstens fördern.In this case, however, the electrical connector is relative sensitive to mechanical loads. Because they are Positioning, orientation and / or dimensions of the first electrical connector and / or in contact therewith to be brought or standing second electrical connector when brought into contact or in the state of contact thereof exactly matched, can be electrical at first Connector forces act due to the relative only a weak or resilient SMT connection points Tear it off the circuit board or at least promote.

Zur Lösung des Problems könnte die Verwendung von sogenannten schwimmenden Verbindern vorgesehen werden, wie sie beispielsweise aus der EP-A-0 301 721, der EP-A-0 549 960, und der US-A-3 673 545 bekannt sind. Bei Verbindern dieser Art sind die Kontaktierungselemente relativ zum Verbindergehäuse bewegbar, so daß sich Fehlausrichtungen von in Kontakt zu bringenden Verbindern durch eine entsprechende Verschiebung der Kontaktierungselemente ausgleichen lassen. Wie aus den genannten Druckschriften ersichtlich ist, weisen derartige Verbinder jedoch andererseits einen relativ komplizierten Aufbau auf und sind dementsprechend groß, wodurch deren Einsetzbarkeit ebenfalls Einschränkungen unterworfen ist.To solve the problem, the use of so-called Floating connectors are provided, such as from EP-A-0 301 721, EP-A-0 549 960, and US-A-3 673 545 are known. With connectors of this type they are Contacting elements movable relative to the connector housing, so that misalignments can be brought in contact Connect by a corresponding displacement of the contacting elements balance. As from the above Such documents can be seen in printed publications on the other hand, however, has a relatively complicated structure and are accordingly large, which makes them usable is also subject to restrictions.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein elektrisches Verbinderpaar der im Oberbegriff des Patentanspruchs 1 beanspruchten Art derart weiterzubilden, daß dieses auch bei einer Oberflächenmontage eines oder beider der in Kontakt zu bringenden elektrischen Verbinder auf beliebig ausgebildete elektrische Leiterplatten eine zuverlässig und dauerhaft feste und sichere Verbindung zwischen den zu verbindenden elektrischen Verbindern gewährleisten kann.The present invention is therefore based on the object an electrical connector pair in the preamble of the claim 1 claimed type in such a way that this even with surface mounting of one or both of the any electrical connector to be brought into contact trained electrical circuit boards a reliable and Permanently firm and secure connection between those to be connected can ensure electrical connectors.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 beanspruchten Merkmale gelöst.This object is achieved by the im Claim 1 claims solved.

Demnach ist bei einem gattungsgemäßen elektrischen Verbinderpaar vorgesehen, daß einander zugeordnete Kontaktierungselemente der elektrischen Verbinder derart ausgebildet sind, daß diese in einer senkrecht zur Kontaktierungsrichtung und einer senkrecht zur Reihenausrichtungsrichtung verlaufenden Querrichtung mit einem einen gegenseitigen Versatz der elektrischen Verbinder erlaubenden Spiel in Kontakt bringbar sind, welches um ein Vielfaches größer ist als ein in der Reihenausrichtungsrichtung vorgesehenes Spiel.Accordingly, in a generic electrical connector pair it is provided that mutually associated contacting elements the electrical connector is formed in this way are that these are in a direction perpendicular to the contacting direction and one perpendicular to the row alignment direction Transverse direction with a mutual offset of the electrical connector allowing game in contact are, which is many times larger than one in the Line alignment direction intended game.

D.h., die einander zugeordneten Kontaktierungselemente sind derart ausgebildet, daß ein Inkontaktbringen und damit auch ein Inkontaktstehen derselben nicht etwa nur an einer mehr oder weniger punktförmigen Stelle, sondern über einen vergleichsweise großen, in Querrichtung stark erweiterten Bereich erfolgen bzw. stattfinden kann. That is, the contacting elements assigned to one another formed such that contacting and thus also contacting them not only on one more or less point-like point, but over a comparative large, greatly expanded area in the transverse direction can take place or take place.

Durch Vorsehen dieses Merkmals ist erreichbar, daß beim Inkontaktbringen und/oder im Kontaktzustand der elektrischen Verbinder in der Querrichtung des ersten elektrischen Verbinders überhaupt keine oder allenfalls relativ schwache Querkräfte wirken, und zwar selbst dann, wenn die Positionierung, die Ausrichtung und/oder die Abmessungen des ersten elektrischen Verbinders und/oder des zweiten elektrischen Verbinders von den Sollwerten erheblich abweichen, d.h. mit hohen Toleranzen behaftet sind. By providing this feature it can be achieved that when contacting and / or in the contact state of the electrical Connector in the transverse direction of the first electrical connector no or only relatively weak transverse forces work, even if the positioning, the orientation and / or dimensions of the first electrical Connector and / or the second electrical connector deviate significantly from the target values, i.e. with high tolerances are afflicted.

Die Verringerung bzw. die gänzliche Eliminierung von in der Querrichtung des ersten elektrischen Verbinders wirkenden Kräften erweist sich in der Regel (aber nicht ausschließlich) als besonders wirkungsvoll, wenn dieser liegend auf der entsprechenden elektrischen Leiterplatte montiert ist, d.h. die Kontaktierungsrichtung parallel zur Leiterplattenoberfläche verläuft, und wenn hierbei der die Verbindungsstellen zwischen dem ersten elektrischen Verbinder und der elektrischen Leiterplatte beinhaltende Anschlußbereich auf der Leiterplatte sich entlang einer Seite des elektrischen Verbinders erstreckt, welche gegenüber von der im folgenden als Stirnseite bezeichneten Seite des ersten elektrischen Verbinders liegt, an welcher der Kontakt mit dem zweiten elektrischen Verbinder hergestellt wird; eine derartige Anordnung des ersten elektrischen Verbinders auf der elektrischen Leiterplatte ist beispielsweise bei Leiterplattenverbindern üblich, welche das Aufstecken einer ersten Leiterplatte (z.B. Baugruppenplatte) auf eine zweite Leiterplatte (z.B. Rückwand) ermöglichen.The reduction or the total elimination of in the Acting transverse direction of the first electrical connector Forces usually prove (but not exclusively) to be particularly effective when it is lying on the corresponding one electrical circuit board is mounted, i.e. the Contact direction parallel to the PCB surface runs, and if here the the connection points between the first electrical connector and the electrical Connection area containing the printed circuit board on the printed circuit board down one side of the electrical connector extends, which is opposite from the following as the end face designated side of the first electrical connector is where the contact with the second electrical Connector is manufactured; such an arrangement of the first electrical connector on the electrical circuit board is common for PCB connectors, for example, which the plugging of a first circuit board (e.g. assembly board) on a second circuit board (e.g. rear wall) enable.

Das Auftreten einer Querkraft bei einem derart montierten ersten elektrischen Verbinder wirkt in diesem Fall nämlich für die Verbindungsstellen als eine Torsions- und/oder Zugkraft, welche infolge des als relativ langer Hebel wirkenden ersten elektrischen Verbinders im Anschlußbereich ein erhebliches Ausmaß annehmen und dadurch schon relativ schnell ein "Abschälen" der SMT-Verbindungsstellen von der Leiterplatte bewirken kann.The occurrence of a lateral force in a first installed in this way electrical connector works in this case for the connection points as a torsional and / or tensile force, which as a result of the first acting as a relatively long lever electrical connector in the connection area a considerable Take on dimensions and therefore a relatively quick one "Peeling" the SMT connection points off the circuit board can effect.

Hinzu kommt, daß sich die die Kraft in Querrichtung des ersten elektrischen Verbinders bzw. die die Torsions- und/oder Zugkraft auf die Verbindungsstellen verursachenden Toleranzen der Positionierung, der Ausrichtung und/oder der Abmessungen des ersten elektrischen Verbinders und/oder des zweiten elektrischen Verbinders bei dieser besonderen Art der Anordnung des ersten elektrischen Verbinders auf der elektrischen Leiterplatte in besonders ungünstiger Weise summieren, und zwar insbesondere dann, wenn es sich um zweiteilige elektrische Verbinder handelt, deren Elemente unabhängig voneinander auf gegenüberliegenden Oberflächen der Leiterplatte montiert sind (erster elektrischer Verbinder) und/oder entsprechend der Sollanordnung des zu kontaktierenden (ersten) elektrischen Verbinders beabstandet auf ein- und der selben Oberfläche der entsprechenden Leiterplatte montiert werden (zweiter elektrischer Verbinder).In addition, the force in the transverse direction of the first electrical connector or the torsion and / or Tensile force on the tolerances causing the connection points positioning, alignment and / or dimensions of the first electrical connector and / or the second electrical Connector in this particular type of arrangement of the first electrical connector on the electrical circuit board add up in a particularly unfavorable manner especially if it is two-part electrical Connector acts, the elements of which are independent opposite surfaces of the circuit board are mounted (first electrical connector) and / or according to the Target arrangement of the (first) electrical to be contacted Spaced on one and the same surface of the connector appropriate circuit board (second electrical Interconnects).

Die die Querkraft bzw. die Torsions- und/oder Zugkräfte verursachenden Toleranzen umfassen in diesem Fall

  • Toleranzen der Dicke und der Krümmung der Leiterplatte(n),
  • Toleranzen des sich jeweils zwischen elektrischem Verbinder und Leiterplatte ausbildenden Spalts,
  • Toleranzen der Positionen bzw. gegenseitigen Abstände der Kontaktierungselemente und/oder der Kontaktöffnungen im Gehäuse des ersten elektrischen Verbinders und des zweiten elektrischen Verbinders, und
  • Toleranzen bei der Positionierung und Ausrichtung des ersten elektrischen Verbinders und des zweiten elektrischen Verbinders auf den jeweiligen Leiterplatten.
In this case, the tolerances causing the transverse force or the torsional and / or tensile forces include

    • Der erste elektrische Verbinder und der zweite elektrische Verbinder sind im vorliegenden Ausführungsbeispiel auf jeweiligen Leiterplatten montierte Leiterplatten-Steckverbinder.The first electrical connector and the second electrical Connectors are on respective in the present embodiment PCB-mounted PCB connectors.

    Die genannten Leiterplatten sind eine Baugruppenplatte 10 und eine Rückwand 20; der erste elektrische Verbinder ist ein Baugruppen-Steckverbinder 30, und der zweite elektrische Verbinder ist ein mit dem Baugruppen-Steckverbinder 30 durch Zusammenstecken in Kontakt bringbarer Rückwand-Steckverbinder 40. The circuit boards mentioned are an assembly board 10 and a rear wall 20; the first electrical connector is a Assembly connector 30, and the second electrical The connector is connected to the module connector 30 Plug-in contactable backplane connectors 40.

    Der Baugruppen-Steckverbinder 30 und der Rückwand-Steckverbinder 40 repräsentieren das erfindungsgemäße elektrische Verbinderpaar.The assembly connector 30 and the backplane connector 40 represent the electrical according to the invention Pair of connectors.

    Der Baugruppen-Steckverbinder 30 ist, wie aus den Figuren ersichtlich ist, derart entlang einer Vorderkante 11 der Baugruppenplatte 10 angeordnet, daß er beim Aufstecken der Baugruppenplatte 10 auf die Oberfläche der Rückwand 20 mit dem darauf montierten Rückwand-Steckverbinder 40 in Kontakt bringbar ist.The module connector 30 is, as can be seen from the figures is along a front edge 11 of the assembly plate 10 arranged that he when plugging the module board 10 on the surface of the rear wall 20 with the backplane connector 40 mounted thereon in contact is feasible.

    Der Baugruppen-Steckverbinder 30 besteht aus zwei identisch ausgebildeten Hälften, wobei die eine der Hälften stumpf auf eine Oberseite 12a der Baugruppenplatte 10 und die andere Hälfte in gleicher Weise auf eine gegenüberliegende Unterseite 12b der Baugruppenplatte 10 gesetzt ist. Die beiden Hälften sind im nicht montierten Zustand völlig unabhängig voneinander; im montierten Zustand bilden sie zusammen mit der zwischen sich eingeschlossenen Baugruppenplatte 10 eine Einheit.The module connector 30 consists of two identical trained halves, with one of the halves being blunt on one top 12a of the assembly board 10 and the other Half in the same way on an opposite underside 12b of the assembly plate 10 is set. The two Halves are completely independent when not assembled from each other; when assembled, they form together with the assembly plate 10 enclosed between them Unit.

    Der auf der Rückwand 20 vorgesehene Rückwand-Steckverbinder 40 besteht ebenfalls aus zwei Hälften. Die Hälften sind parallel zueinander mit einem der Dicke der Baugruppenplatte 10 entsprechenden Abstand bzw. entsprechend der Sollanordnung des Baugruppen-Steckverbinders 30 auf der im gesteckten Zustand der Baugruppenplatte 10 zugewandten Oberfläche der Rückwand 20 angeordnet.The rear wall connector provided on the rear wall 20 40 also consists of two halves. The halves are parallel to each other with one of the thickness of the assembly board 10 corresponding distance or according to the target arrangement of the module connector 30 on the in the inserted state the surface of the assembly plate 10 facing the Rear wall 20 arranged.

    Wie aus Figur 1 ersichtlich ist, sind die jeweiligen Hälften des Baugruppen-Steckverbinders 30 in ihrer Längsrichtung aus aneinandergereihten, relativ kurzen Steckverbinder-Modulen 15 zusammengesetzt. Die Größe der jeweiligen Steckverbinder-Module 15 ist so bemessen, daß diese in herkömmliche Streifenverpackungen passen und unter Einsatz herkömmlicher Bestückungsmaschinen automatisch verarbeitet werden können. Entsprechendes gilt auch für den Rückwand-Steckverbinder 40. As can be seen from Figure 1, the respective halves of the module connector 30 in its longitudinal direction lined up, relatively short connector modules 15 composed. The size of the respective connector modules 15 is dimensioned so that it is in conventional strip packaging fit and using conventional pick and place machines can be processed automatically. The same applies to the rear wall connector 40.

    Der Baugruppen-Steckverbinder 30 ist liegend auf der Baugruppenplatte 10 montiert. D.h., das Steckergesicht, über welches der Baugruppen-Steckverbinder 30 mit dem Rückwand-Steckverbinder 40 in Kontakt bringbar ist, ist im auf der Baugruppenplatte 10 montierten Zustand des Baugruppen-Steckverbinders 30 in einer seitlichen, der Vorderkante 11 der Baugruppenplatte 10 zugewandten Außenfläche desselben, also der im auf die Rückwand 20 gesteckten Zustand des Baugruppen-Steckverbinders 10 der Rückwand 20 zugewandten Stirnseite 31 ausgebildet. Die Stirnseite 31 steht im auf der Baugruppenplatte 10 montierten Zustand des Baugruppen-Steckverbinders 30 im wesentlichen senkrecht auf der Oberseite 12a bzw. der Unterseite 12b der Baugruppenplatte 10.The assembly connector 30 is lying on the assembly board 10 mounted. That is, the connector face over which the assembly connector 30 with the rear wall connector 40 can be brought into contact is on the assembly board 10 assembled state of the module connector 30 in a lateral, the front edge 11 of the assembly plate 10 facing outer surface of the same, that is, in the the rear wall 20 inserted state of the module connector 10 of the rear wall 20 facing end face 31 is formed. The end face 31 is in the assembly plate 10 assembled state of the module connector 30 in substantially perpendicular to the top 12a or the bottom 12b of the assembly plate 10.

    Die Stirnseite 31 weist, wie in der Figur 1 angedeutet ist, eine Vielzahl von Kontaktöffnungen 32 auf, hinter welchen sich jeweilige Kontaktierungselemente in Form von in den Figuren nicht gezeigten Kontaktfedern befinden. Beim im wesentlichen senkrechten Aufstecken der Baugruppenplatte 10 auf die Rückwand 20, d.h. bei relativer Bewegung der Baugruppenplatte 10 und der Rückwand 20 in eine parallel zur Baugruppenplatte und senkrecht zur Rückwand verlaufende Kontaktierungsrichtung gelangen Kontaktierungselemente in Form von Kontaktmessern 41 des Rückwand-Steckverbinders 40 durch die Kontaktöffnungen 32 hindurch mit den Kontaktfedern in Kontakt.The end face 31, as indicated in FIG. 1, a plurality of contact openings 32, behind which respective contacting elements in the form of in the figures contact springs, not shown. At essentially vertically plugging the assembly plate 10 onto the Rear wall 20, i.e. with relative movement of the assembly plate 10 and the rear wall 20 in a parallel to the assembly board and contact direction running perpendicular to the rear wall contact elements in the form of contact blades 41 of the rear wall connector 40 through the contact openings 32 through in contact with the contact springs.

    Die Kontaktöffnungen 32 und die denselben zugeordneten Kontaktfedern sind in mindestens einer, sich in einer Reihenausrichtungsrichtung erstreckenden Reihe angeordnet, wobei die Reihenausrichtungsrichtung beim vorliegenden Ausführungsbeispiel parallel zur Oberfläche der Baugruppenplatte 10 und senkrecht zur Kontaktierungsrichtung verläuft. Falls mehrere Reihen vorgesehen sind, sind diese im vorliegenden Ausführungsbeispiel in der in den Figuren gezeigten Weise übereinander liegend ausgebildet. Die Anzahl der Elemente pro Reihe ist dabei in der Regel jedoch größer als die Anzahl der Reihen.The contact openings 32 and the contact springs assigned to them are in at least one, in a row alignment direction extending row arranged, the Row alignment direction in the present embodiment parallel to the surface of the assembly plate 10 and runs perpendicular to the direction of contact. If more Rows are provided, these are in the present embodiment one above the other in the manner shown in the figures trained lying. The number of elements per row is usually larger than the number of rows.

    Der Baugruppen-Steckverbinder 30 ist mit der Baugruppenplatte 10 durch Oberflächenmontage bzw. nach einem SMT-Verfahren verbunden. Er weist hierzu abgewinkelte Lötstiele 33 auf, die an einer der Stirnseite 31 gegenüberliegenden Rückseite aus dem Baugruppen-Steckverbinder 30 austreten und in einem hierzu benachbarten Anschlußbereich der Baugruppenplatte 10 mit derselben verlötet werden.The module connector 30 is with the module plate 10 by surface mounting or using an SMT process connected. For this purpose, it has angled soldering sticks 33 which on a rear side opposite the front side 31 emerge from the module connector 30 and in one for this purpose adjacent connection area of the module board 10 with the same are soldered.

    Durch Oberflächenmontage bzw. nach einem SMT-Verfahren hergestellte Verbindungen sind bekanntermaßen wenig belastbar und bedürfen daher besonderer Aufmerksamkeit beim Entwurf.Manufactured by surface mounting or by an SMT process Connections are known to be little resilient and therefore need special attention when designing.

    Um ein Lösen bzw. Zerstören derartiger Verbindungen zu verhindern, ist beim vorliegenden Ausführungsbeispiel vorgesehen, die Kontaktöffnungen 32 und die dahinter liegenden Kontaktfedern derart auszubilden, daß - wie in den Figuren angedeutet - diese bzw. deren zum Inkontaktbringen und Inkontaktstehen vorgesehene Inkontaktbringungsabschnitte in einer senkrecht zur Kontaktierungsrichtung und einer senkrecht zur Reihenausrichtungsrichtung verlaufenden Querrichtung eine größere Ausdehnung aufweisen als in der Reihenausrichtungsrichtung. Die jeweiligen Abmessungen, Anordnungen und Gestaltungen der einander zugeordneten Kontaktfedern des ersten elektrischen Verbinders und Kontaktmesser des zweiten elektrischen Verbinders sind dabei erfindungsgemäß derart gewählt, daß diese in einer senkrecht zur Kontaktierungsrichtung und einer senkrecht zur Reihenausrichtungsrichtung verlaufenden Querrichtung mit einem einen gegenseitigen Versatz der elektrischen Verbinder erlaubenden ein- oder beidseitigen Spiel in Kontakt bringbar sind, welches um ein Vielfaches größer ist als ein in der Reihenausrichtungsrichtung vorgesehenes Spiel. Das Spiel in Querrichtung sollte in etwa das Doppelte des Spiels in Reihenausrichtungsrichtung oder mehr betragen, kann selbstverständlich aber auch kleiner sein; vorzugsweise beträgt es ungefähr das zwei- bis vierfache des Spiels in Reihenausrichtungsrichtung.In order to prevent loosening or destruction of such connections, is provided in the present embodiment, the contact openings 32 and the contact springs located behind them to be trained in such a way that - as indicated in the figures - These or their for contacting and being in contact provided contacting sections in one perpendicular to the direction of contact and one perpendicular to Row alignment direction transverse direction one have a larger dimension than in the row alignment direction. The respective dimensions, arrangements and designs the mutually associated contact springs of the first electrical connector and contact knife of the second Electrical connectors are according to the invention chosen that this in a perpendicular to the direction of contact and one perpendicular to the row alignment direction Transverse direction with a mutual offset the electrical connector allowing one or both sides Game can be brought into contact, which is many times is larger than that provided in the row alignment direction Game. The game in the transverse direction should be about that Double the game in row alignment direction or more amount, but can of course also be smaller; preferably it is approximately two to four times that Game in row alignment direction.

    Die Kontaktfedern des Baugruppen-Steckverbinders 30 und die jeweils zugeordneten Kontaktmesser 41 des Rückwand-Steckverbinders 40 können daher innerhalb eines relativ groß bemessenen Bereichs, und zwar an jeder Stelle gleichermaßen gut (widerstandslos), elektrisch und mechanisch in Kontakt gebracht und gehalten werden. Durch eine derartige Gestaltung der Kontaktierungselemente ist ein gegenseitiger Versatz der in Kontakt zu bringenden Kontaktfedern und Kontaktmesser (infolge eines nicht zentrierten Zusammensteckens, einer nicht exakten Montage der Steckverbinder bzw. Steckverbindermodule auf den jeweiligen Leiterplatten oder Fertigungstoleranzen der einzelnen Elemente) beim Zusammenstecken derselben ausgleichbar, ohne daß auf die jeweiligen Steckverbinder Kräfte wirken, welche ein Lösen der relativ empfindlichen Verbindungen zwischen Steckverbinder und Leiterplatte zur Folge haben können. Insbesondere ist dadurch zuverlässig verhinderbar, daß an der Stirnseite des Baugruppen-Steckverbinders in Querrichtung wirkende Kräfte auftreten, welche für die Verbindungsstellen zwischen Baugruppen-Steckverbinder und Baugruppenplatte als Torsions- und/oder Zugkräfte wirken, gegen die die Verbindungsstellen besonders empfindlich sind.The contact springs of the module connector 30 and each associated contact knife 41 of the rear wall connector 40 can therefore be within a relatively large size Area, and equally good at every point (without resistance), electrically and mechanically brought into contact and be held. With such a design the contacting elements is a mutual offset of the contact springs and contact knives to be brought into contact (as a result of a non-centered assembly, one inexact assembly of the connector or connector module on the respective printed circuit boards or manufacturing tolerances of the individual elements) when putting them together compensable without having to click on the respective connector Forces act which release the relatively sensitive Connections between the connector and the circuit board May have consequence. In particular, this reliably prevents that on the front of the module connector transversely acting forces occur which for the connection points between module connectors and Module plate act as torsion and / or tensile forces against the connection points are particularly sensitive.

    Alternativ oder zusätzlich hierzu kann der Baugruppen-Steckverbinder 30 an seiner im auf der Baugruppenplatte 10 montierten Zustand dem Anschlußbereich der Baugruppenplatte gegenüberliegenden Seite mit einem Halteelement versehen sein, das mit der Baugruppenplatte 10 fest verbindbar ist. Ein derartiges Halteelement kann beispielsweise, wie in den Figuren gezeigt ist, durch ein an der Stirnseite 31 vorgesehenes, sich vorzugsweise im wesentlichen über die gesamte Länge des Baugruppen-Steckverbinders 30 bzw. der jeweiligen Steckverbinder-Module 15 erstreckendes Halteblech 34 gebildet werden, welches im Bereich der Vorderkante des Baugruppen-Steckverbinders mit diesem (vorzugsweise unter Verwendung eines SMT-Verfahrens) verlötbar ist.Alternatively or in addition, the module connector can 30 on his in the assembled on the board 10 Condition opposite the connection area of the module board Side with a holding element, that can be firmly connected to the assembly board 10. Such a thing Holding element can, for example, as in the figures is shown, by a provided on the end face 31, preferably substantially over the entire length of the Module connector 30 or the respective connector modules 15 extending holding plate 34 are formed, which is in the area of the front edge of the module connector with this (preferably using an SMT process) is solderable.

    Die Erfindung wurde vorstehend anhand einer Leiterplatten-Steckverbinderanordnung beschrieben. Hierauf besteht jedoch keine Einschränkung; die Erfindung ist vielmehr bei elektrischen Verbindern beliebiger Art einsetzbar, denn beim Inkontaktbringen und/oder im Kontakt zustand die Verbinder und/oder die Verbindung nachteilig beeinflussende Kräfte, die durch die erfindungsgemäße Gestaltung des Verbinderpaars vermeidbar sind, könnten bei nahezu allen Arten von elektrischen Verbindern auftreten.The invention has been described above using a printed circuit board connector arrangement described. However, insists no restriction; rather, the invention is in electrical Connectors of any kind can be used, because when they are brought into contact and / or in contact the connectors and / or forces adversely affecting the connection the inventive design of the connector pair avoidable with almost all types of electrical connectors occur.

    Der erste elektrische Verbinder (Baugruppen-Steckverbinder 30) ist im beschriebenen Ausführungsbeispiel liegend auf einer Leiterplatte (Baugruppenplatte 10) montiert. Auch hierauf besteht keine Einschränkung; die Erfindung ist vielmehr in entsprechender Weise auch bei stehend oder in sonstiger Weise auf einer Leiterplatte montierten oder montierbaren elektrischen Verbindern nutzbringend einsetzbar, weil auch hier beim Inkontaktbringen und/oder beim Außerkontaktbringen und/oder im Kontaktzustand mit einem entsprechenden Gegenstück auf den elektrischen Verbinder wirkende Kräfte erzeugt werden können, die ihrerseits wiederum auf die Verbindungsstellen zwischen elektrischem Verbinder und Leiterplatte als (durch die erfindungsgemäße Gestaltung vermeidbare) Torsions- und/oder Zugkräfte wirken.The first electrical connector (assembly connector 30) is lying on in the exemplary embodiment described a printed circuit board (assembly board 10). Here too there is no restriction; rather, the invention is in a corresponding manner also when standing or in another Way mounted or mountable on a circuit board electrical connectors can be used beneficially because too here when contacting and / or bringing out of contact and / or in contact with a corresponding counterpart forces acting on the electrical connector can, in turn, on the connection points between electrical connector and circuit board as (Avoidable by the design according to the invention) and / or tensile forces act.
