Description

Die Erfindung betrifft einen Leiterplattenlötmontage-Steckverbinder, mit einem Isolierkörper und mindestens einem darin in einer Aufnahmekammer aufgenommenen länglichen elektrischen Steckkontakt, der sich zwischen einem einer Leiterplatte zugeordneten Fußteil und einem dem Fußteil mit Abstand gegenüberliegenden Kopfteil des Isolierkörpers erstreckt, wobei der mindestens eine Steckkontakt an einem dem Kopfteil nahen vorderen Ende einen zugänglichen elektrisch kontaktierbaren Steckbereich, einen daran anschließenden Zentralbereich und darauf folgend an einem dem Fußteil nahen hinteren Ende einen freiliegenden Lötbereich aufweist, wobei der Zentralbereich eine an den Steckbereich anschließende zylinderförmige biegestarre Haltezone und eine sich zwischen der Haltezone und dem Lötbereich erstreckende zylindrische nachgiebig ausgebildete Deformationszone aufweist, so dass der Steckbereich des mindestens einen Steckkontakts gegenüber dem Lötbereich bei Deformierung der Deformationszone seitlich verschiebbar ist, wobei der mindestens eine Steckkontakt zumindest im Bereich der Deformationszone innen hohl ausgebildet ist.The invention relates to a Leiterplattenlötmontage connector, comprising an insulating body and at least one received therein in a receiving chamber elongated electrical plug contact extending between a printed circuit board associated foot part and the foot part at a distance opposite head portion of the insulator, wherein the at least one plug contact on a the headboard near the front end of an accessible electrically contactable plug-in area, an adjoining central region and subsequently at a foot near the rear end has an exposed soldering area, wherein the central region of an adjoining the plug-in area cylindrical rigid holding zone and a between the holding zone and the soldering area extending cylindrical yielding deformable deformation zone, so that the plug-in area of the at least one plug contact with respect to the soldering area in deformation of Deforma tion zone is laterally displaceable, wherein the at least one plug contact is hollow at least in the region of the deformation zone.

Ein Problem bei elektrischen Steckverbindern ist es, ineinander steckbare Buchsen- und Stift-Steckverbinder, von denen mindestens ein Steckverbinder zum Verlöten mit einer Leiterplatte vorgesehen ist, zu liefern, die trotz einer gewissen Fehlausrichtung einiger oder aller buchsen- oder stiftförmigen Steckkontakte nach dem Verlöten mit der Leiterplatte problemlos in einer toleranzbehafteten Aufnahme angeordnet werden können. Dieses Problem tritt insbesondere dann auf, wenn der zu verlötende Leiterplattenlötmontage-Steckverbinder eine große Anzahl von Steckkontakten aufweist oder wenn mehrere Buchsen- und/oder Stift-Steckverbinder auf einer Leiterplatte nebeneinander angeordnet sind und die elektrische Verbindung über einen gemeinsamen Gruppenstecker in einer toleranzbehafteten Aufnahme hergestellt werden soll. Der dabei auftretende Versatz der einzelnen Steckkontakte und damit auch der die Steckkontakte aufnehmenden Isolierkörper ist durch Fertigungstoleranzen der Leiterplatte, der elektrischer Steckverbinder und beim Verlöten der Buchsen- oder Stift-Steckverbinder mit der Leiterplatte bedingt. Dieses Problem ist besonders groß bei als oberflächenmontierbares Bauelement ausgebildeten elektrischen Leiterplattenlötmontage-Steckverbindern. Wenn die Position des Isolierkörpers solcher Streckverbinder nicht wie konstruktiv vorgesehen eingehalten wird, können auch Schwierigkeiten auftreten, wenn ein Gehäuseteil mit den/die verlöteten Steckverbinder aufnehmenden Kammern oder Durchbrüchen, den jeweiligen Isolierkörper um- und/oder übergreifend, gefügt werden sollen.One problem with electrical connectors is that they can be plugged into one another into socket and pin connectors, of which at least one connector is provided for soldering to a printed circuit board, which despite a certain misalignment of some or all socket or pin-shaped plug contacts after soldering to the circuit board can be easily arranged in a tolerance-sensitive recording. This problem occurs in particular when the soldering circuit board connector to be soldered has a large number of plug contacts or when a plurality of socket and / or pin plug connectors are arranged next to one another on a printed circuit board and the electrical connection is made via a common group plug in a tolerance-sensitive receptacle shall be. The occurring offset of the individual plug contacts and thus also the plug contacts receiving insulator is caused by manufacturing tolerances of the circuit board, the electrical connector and soldering the female or male connectors to the circuit board. This problem is particularly great when designed as a surface mount device electrical Leiterplattenlötmontage connectors. If the position of the insulating body of such stretch connector is not complied with as intended, difficulties may also arise if a housing part with the / the soldered connector receiving chambers or openings, the respective insulator um- and / or across, are to be joined.

Zur Lösung des Problems ist es bekannt, die Steckkontakte schwimmend in dem jeweiligen Isolierkörper aufzunehmen. Beispielhaft wird auf die Druckschriften EP 1 861 898 A1 und EP 0 806 814 A1 verwiesen. Die Fehlausrichtung der Steckkontakte wird dabei jedoch nicht korrigiert, so dass die Gegensteckkontaktteile des Gegensteckverbinders nur schwer mit den Steckkontakten des jeweiligen verlöteten Leiterplattenlötmontage-Steckverbinders verbindbar sind und die Lötstellen der Steckkontakte mit hoher Kraft beaufschlagen. Dies kann auf Dauer zur Schädigung der Lötstellen führen. Außerdem können die Steckkontakte des mindestens einen aufgelöteten Leiterplattenlötmontage-Steckverbinders und/oder die Gegensteckkontaktteile des Gegensteckverbinders beschädigt, eventuell sogar unbrauchbar werden.To solve the problem, it is known to receive the plug contacts floating in the respective insulator. By way of example, reference is made to the documents EP 1 861 898 A1 and EP 0 806 814 A1 directed. However, the misalignment of the plug contacts is not corrected, so that the mating plug contact parts of the mating connector are difficult to connect to the plug contacts of the respective soldered PCB mounting connector and act on the solder joints of the plug contacts with high force. This can permanently lead to damage to the solder joints. In addition, the plug contacts of at least one soldered Leiterplattenlötmontage connector and / or the mating plug contact parts of the mating connector may be damaged, possibly even unusable.

Ein gattungsgemäße Steckverbinder ist als Stand der Technik aus der Druckschrift US 5 769 652 A bekannt. Diese Schrift offenbart einen Koaxialverbinder mit einem vorderen und hinteren Körper und vorderen und hinteren Kontakten, die seitlich relativ zueinander verschiebbar sind, um ein problemloses Verbinden mit einem anderen komplementär ausgebildeten Koaxialverbinder zu ermöglichen, der aufgrund von Fertigungstoleranzen geringfügig zu den Kontakten versetzt angeordnete Gegenkontakte aufweist. Eine Federscheibe zwischen dem vorderen und hinteren Körper gewährleistet eine sicheren Kontakt zwischen den vorderen und hinteren Körpern und richtet diese Körper achsparallel miteinander aus. Des Weiteren erlaubt eine die vorderen und hinteren Kontakte elektrisch leitend verbindende Schraubenfeder, die im vorderen Körper aufgenommen vorderen Kontakte relativ zu den hinteren Kontakten des hinteren Körpers seitlich zu verschieben.A generic connector is known as the prior art from the document US 5,769,652 A known. This document discloses a coaxial connector having front and rear bodies and front and rear contacts slidable laterally relative to one another to allow easy connection to another complementary coaxial connector having mating contacts slightly offset from the contacts due to manufacturing tolerances. A spring washer between the front and rear body ensures a secure contact between the front and rear bodies and aligns these bodies axially parallel to each other. Further, a coil spring electrically connecting the front and rear contacts allows the front contacts to be laterally displaced relative to the rear contacts of the rear body in the front body.

Der elektrische Kontakt ist vorzugsweise einteilig ausgeführt, wobei das flexible Element insbesondere als Spiralfeder mit rechteckigem Querschnitt ausgebildet oder von zwei orthogonal miteinander verbundenen Blattfedern gebildet ist.Another such electrical connector is in the document DE 10 2010 037 498 A1 disclosed. This prior art teaches an electrical contact for an electrical connector having a flexible element between a terminal portion fixed in a housing and a movable contact portion, wherein the movement of the contact portion and / or the deformation of the flexible member in the direction of an axis parallel to the Plugging direction of the contact area is limited. The electrical contact is preferably made in one piece, wherein the flexible element is designed in particular as a spiral spring with a rectangular cross-section or formed by two orthogonally interconnected leaf springs.

This document describes a current-carrying contact with a first plug contact and a second plug contact, which are conductively connected to one another via a contact element. Between the plug contacts and the contact element takes place on contact surfaces an electrical contact, wherein the contact element one, an angular offset and / or has an axial offset between the plug contacts compensating deformable portion.

Ausgehend von dem vorstehend beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit für einen Toleranzausgleich zwischen mit einer Leiterplatte verlöteten Steckkontakten mindestens eines Leiterplattenlötmontage-Steckverbinders und einer Aufnahme für den bzw. die Isolierkörper, in dem/denen die metallischen Steckkontaktteile aufgenommen sind, vorzuschlagen.Based on the above-described prior art, the invention has the object, a possibility for a tolerance compensation between soldered to a circuit board plug contacts at least one Leiterplattenlötmontage connector and a receptacle for the or the insulator, in which / which the metallic plug contact parts are added to propose.

Diese Aufgabe wird erfindungsgemäß durch einen elektrischen Leiterplattenlötmontage-Steckverbinder mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den rückbezogenen Ansprüchen zu entnehmen. Die Aufgabe wird außerdem durch eine Steckverbinderanordnung gemäß dem Anspruch 8 gelöst.This object is achieved by an electrical Leiterplattenlötmontage connector with the features of claim 1. Further advantageous embodiments can be found in the dependent claims. The object is also achieved by a connector assembly according to claim 8.

Bei dem eingangs beschriebenen Leiterplattenlötmontage-Steckverbinder ist der Steckbereich mit einem Stift oder einer Buchse ausgeführt und der Lötbereich für die durch Steck- oder Oberflächenmontage auf der Leiterplatte gestaltet. Der Zentralbereich des erfindungsgemäßen Leiterplattenlötmontage-Steckverbinders weist wie bekannt eine an den Steckbereich anschließende zylinderförmige biegestarre Haltezone und eine sich zwischen der Haltezone und dem Lötbereich erstreckende zylindrische nachgiebig ausgebildete Deformationszone auf, so dass der Steckbereich des mindestens einen Steckkontakts gegenüber dem Lötbereich bei Deformierung der Deformationszone seitlich verschiebbar ist. Der Steckbereich ist in der Aufnahmekammer über die Haltezone geführt und wird so bei der Deformierung der Deformationszone, die durch seitliche Krafteinwirkung auf den Isolierkörper einfach möglich ist, nicht beeinflusst. Der Lötbereich ist ohnehin nach dem Verlöten mit der Leiterplatte über die Lötstelle an der Leiterplatte fixiert und stabilisiert, so dass dieser lage- und formstabil ist. Idealerweise wird die Deformationszone gegenüber der Haltezone des Zentralbereiches und gegenüber dem Lötbereich geometrisch derart gestaltet, dass die Deformationszone diesen gegenüber mit geringem Kraftaufwand im wesentlichen seitlich verformbar ist. Damit ist eine seitliche Verschiebung des Isolierkörpers gegenüber der Leiterplatte möglich, um geringfügige Lagekorrekturen vorzunehmen, wobei der Steckbereich des mindestens einen Steckkontakts nicht verformt wird. Entsprechend dem Stand der Technik ist der mindestens eine Steckkontakt zumindest im Bereich der Deformationszone innen hohl ausgebildet.In the Leiterplattenlötmontage connector described above, the plug-in area is designed with a pin or a socket and designed the soldering area for by plug or surface mounting on the circuit board. As is known, the central region of the printed circuit board solder-mounting connector according to the invention has a cylindrical bending-resistant holding zone extending between the holding zone and the soldering region and a deformable deformation zone extending between the holding zone and the soldering region, such that the plug-in region of the at least one plug-in contact bears laterally with respect to the soldering region when the deformation zone is deformed is displaceable. The plug-in area is guided in the receiving chamber over the holding zone and is thus not affected in the deformation of the deformation zone, which is easily possible by lateral force on the insulating body. The soldering area is anyway fixed and stabilized after soldering to the circuit board via the soldering to the circuit board, so that it is stable in position and shape. Ideally, the deformation zone is geometrically designed with respect to the holding zone of the central region and with respect to the soldering region in such a way that the deformation zone faces the latter with little effort in the is substantially laterally deformable. In order for a lateral displacement of the insulating body relative to the circuit board is possible to make minor positional corrections, wherein the mating portion of the at least one plug contact is not deformed. According to the prior art, the at least one plug-in contact is hollow at least in the region of the deformation zone.

Erfindungsgemäß ist der mindestens eine Steckkontakt einstückig hergestellt und weist eine Deformationszone mit mindestens zwei quer und/oder schräg zu der Längsachse des mindestens einen Steckkontaktes verlaufenden, in axialer Richtung versetzt zueinander angeordnete Durchbrüchen auf, die sich jeweils in einer Ebene mindestens über die Hälfte der Umfangswand der Deformationszone erstrecken, wobei die Durchbrüche Querschlitze und/oder Schrägschlitze sowie parallel zu der Längsachse des Steckkontaktes verlaufende Längsschlitze aufweisen. Dabei sind die Querschlitze und/oder Schrägschlitze endseitig mit den Längsschlitzen verbunden und greifen vorzugsweise mittig in die Längsschlitze ein.According to the invention, the at least one plug-in contact is manufactured in one piece and has a deformation zone with at least two transversely and / or obliquely to the longitudinal axis of the at least one plug contact extending, offset in the axial direction to each other arranged breakthroughs, each in a plane at least over half of the peripheral wall extend the deformation zone, wherein the openings have transverse slots and / or slanted slots and extending parallel to the longitudinal axis of the plug contact longitudinal slots. The transverse slots and / or inclined slots are connected at the end to the longitudinal slots and preferably engage centrally in the longitudinal slots.

Durch den vorhandenen Hohlraum, der günstigerweise ebenfalls zylindrisch ausgebildet ist, wird die Stabilität des Zentralbereiches in der Deformationszone deutlich geschwächt, wobei sich der Hohlraum bis in den Lötbereich fortsetzen kann. Dabei ist der Durchmesser des Hohlraums bevorzugt derart gewählt, dass die Deformationszone des Zentralbereiches nur noch eine Umfangswand geringer Stärke, jedoch ausreichend für die zu übertragende Stromstärke, gegenüber dem Durchmesser des Zentralbereiches aufweist. Dies erleichtert die Deformierung der Deformationszone und damit eine seitliche Verschiebung des Steckbereiches gegenüber dem Lötbereich erheblich. Gemäß der Erfindung weist die Deformationszone des Leiterplattenlötmontage-Steckverbinders außerdem mindestens zwei quer und/oder schräg zur Längsachse des mindestens einen Steckkontakts verlaufende, in axialer Richtung versetzt zueinander angeordnete Durchbrüche auf, die sich jeweils in einer Ebene mindestens über die Hälfte der Umfangswand der Deformationszone erstrecken. Die Durchbrüche unterteilen die Deformationszone in einzelne Deformationszonen-Segmente, die nur noch über einen Teil der Umfangswand des Zentralbereiches miteinander und/oder der Haltezone mit dem daran anschließenden Steckbereich bzw. mit dem Lötbereich verbunden sind. Die Verbindungsstellen der Deformationszonen-Segmente sind diejenigen Stellen der Deformationszone, die besonders nachgiebig sind. Sie ermöglichen ein seitliches Verkippen der Deformationszonen-Segmente einander gegenüber, wobei die Größe der Durchbrüche ab und/oder zunimmt. Die Deformationszone kann in diesem Fall zwei oder mehr nur quer, nur schräg oder quer und schräg verlaufende Durchbrüche aufweisen, wobei sich die Ebenen, in denen sich die Durchbrüche jeweils erstrecken, vorzugsweise in einem beliebigen typischen Winkel zwischen 0 und 45° einander gegenüber und im Hinblick auf eine Orthogonale der Längsachse des Steckkontaktes erstrecken.Due to the existing cavity, which is favorably also cylindrical, the stability of the central region in the deformation zone is significantly weakened, whereby the cavity can continue into the soldering area. In this case, the diameter of the cavity is preferably chosen such that the deformation zone of the central region has only one peripheral wall of small thickness, but sufficient for the current to be transmitted, compared to the diameter of the central region. This considerably facilitates the deformation of the deformation zone and thus a lateral displacement of the plug-in area relative to the soldering area. According to the invention, the deformation zone of the circuit board solder-mounting connector also has at least two transversely and / or obliquely to the longitudinal axis of the at least one plug-in contact, arranged offset in the axial direction to each other Breakthroughs, each extending in a plane at least over half of the peripheral wall of the deformation zone. The apertures subdivide the deformation zone into individual deformation zone segments, which are connected to each other only over part of the peripheral wall of the central region and / or the holding zone to the adjoining plug region or to the soldering region. The junctions of the deformation zone segments are those points of the deformation zone that are particularly yielding. They allow a lateral tilting of the deformation zone segments opposite each other, wherein the size of the openings decreases and / or increases. The deformation zone may in this case have two or more only transversely, only obliquely or transversely and obliquely extending apertures, wherein the planes in which the apertures each extend, preferably at any typical angle between 0 and 45 ° to each other and in the With respect to an orthogonal extend the longitudinal axis of the plug contact.

Zweckmäßigerweise weist die Deformationszone örtlich bestimmte Abschnitte auf, in denen die Stabilität herabgesetzt ist. Wesentlich ist dabei, dass diese Abschnitte derart ausgebildet und angeordnet sind, dass sie problemlos eine seitliche Verschiebung des Steckbereiches gegenüber dem Lötbereich in eine beliebige Richtung parallel zur Leiterplatte ermöglichen, ohne dass wesentliche Kräfte senkrecht und/oder parallel zu der Leiterplatte zwischen der Lötstelle und der Haltezone des Steckkontakts auftreten. Auf diese Weise ist das Fügen des Isolierkörpers in eine Aufnahme bei einer geringen Fehlpositionierung jederzeit möglich und am Kopfteil des Isolierkörpers des erfindungsgemäßen Leiterplattenlötmontage-Steckverbinders immer ein Gegensteckverbinder mit komplementär ausgebildeten Gegensteckkontakten mit den Steckkontakten des Steckbereiches koppelbar.Expediently, the deformation zone has locally determined sections in which the stability is reduced. It is essential that these sections are designed and arranged so that they easily allow a lateral displacement of the mating area relative to the soldering in an arbitrary direction parallel to the circuit board without significant forces perpendicular and / or parallel to the circuit board between the solder joint and the Holding zone of the plug contact occur. In this way, the joining of the insulating in a receptacle at a low mispositioning is always possible and at the head of the insulator of Leiterplattenlötmontage connector according to the invention always a mating connector with complementary mating plug contacts coupled with the plug contacts of the plug-in area.

Vorzugsweise fixiert die Haltezone des Zentralbereichs den Steckbereich des mindestens einen Steckkontaktes zumindest seitlich unverrückbar in der Aufnahmekammer, wobei zwischen dem Isolierkörper und dem mindestens einen Steckkontakt im Bereich der Deformationszone in der Aufnahmekammer ein Ringspalt ausgebildet ist, so dass die Deformationszone bei seitlicher Kraftbeaufschlagung des Isolierkörpers in den Ringspalt hinein verformbar ist. Durch den Ringspalt weist die Deformationszone zu der Innenwand der Aufnahmekammer rundum einen seitlichen Abstand auf, so dass dort der Zentralbereich quer zur Längsachse des Steckkontaktes biegbar oder knickbar ist. Die entsprechende Wand der Aufnahmekammer dient damit gleichzeitig als Begrenzung für die Auslenkung. Es ist aber auch möglich, auf die einzelnen die Deformationszone jedes Steckkontaktes umgebenden Wände der Aufnahmekammer zu verzichten. Diese ist insbesondere bei kleinen Leiterplattenlötmontage-Steckverbindern mangels Raum für eine ausreichende Wandstärke zwangsläufig notwendig. Die Deformationszonen aller Steckkontakte werden dann nur von einer gemeinsamen Wand umschlossen, die bis zum Lötbereich reichen kann, und bilden einen gemeinsamen Aufnahmekammerabschnitt.Preferably, the holding zone of the central region fixes the insertion region of the at least one plug-in contact at least laterally immovably in the receiving chamber, wherein between the insulating body and the at least one Plug contact in the region of the deformation zone in the receiving chamber, an annular gap is formed, so that the deformation zone in lateral force loading of the insulating body is deformable into the annular gap. Through the annular gap, the deformation zone to the inner wall of the receiving chamber around a lateral distance, so that there is the central region transversely to the longitudinal axis of the plug contact bendable or bendable. The corresponding wall of the receiving chamber thus serves as a limit to the deflection. But it is also possible to dispense with the individual surrounding the deformation zone of each plug contact walls of the receiving chamber. This is inevitably necessary especially for small Leiterplattenlötmontage connectors lack of space for a sufficient wall thickness. The deformation zones of all plug contacts are then enclosed only by a common wall, which can extend to the soldering area, and form a common receiving chamber section.

Die Haltezone des Zentralbereiches, von dem sich der Steckbereich in axialer Richtung weg erstreckt, kann mit der Aufnahmekammer verrastet, in diese eingepresst, eingegossen oder dort in einer anderen Art befestigt sein. Abhängig von der Art der Fixierung des Steckkontaktes in der Aufnahmekammer ist die Haltezone dort mehr oder weniger spielfrei verankert. Insbesondere kann dabei der Steckkontakt in der Aufnahmekammer in axialer Richtung minimal beweglich geführt sein, so dass bei einer Verformung der zylindrischen nachgiebig ausgebildeten Deformationszone, beispielsweise beim seitlichen Biegen oder Knicken des Zentralbereiches, die Haltezone sich gegenüber der Aufnahmekammer minimal verschieben kann.The holding zone of the central region, from which the plug-in region extends in the axial direction, can be latched with the receiving chamber, pressed into it, cast in, or fastened there in another way. Depending on the type of fixation of the plug contact in the receiving chamber, the holding zone is anchored there more or less free of play. In particular, the plug-in contact in the receiving chamber can be guided to be minimally movable in the axial direction, so that the holding zone can shift minimally with respect to the receiving chamber in the case of deformation of the cylindrical resiliently formed deformation zone, for example during lateral bending or bending of the central region.

Erfindungsgemäß weisen die Durchbrüche Querschlitze und/oder Schrägschlitze sowie parallel zu der Längsachse des Steckkontaktes verlaufende Längsschlitze auf und die Querschlitze und/oder Schrägschlitze sind endseitig mit den Längsschlitzen verbunden sind und greifen in die Längsschlitze vorzugsweise mittig ein. Die zusätzlichen Längsschlitze schwächen die Steifigkeit der Deformationszone weiter. Sie sind vorzugsweise wesentlich breiter ausgeführt als die Quer- und/oder Schrägschlitze. Damit reduziert sich die für die Verformung der Deformationszone notwendige Kraft nochmals deutlich. Außerdem wird damit erreicht, dass die von den mindestens zwei Quer- und/oder Schrägschlitzen gebildeten Deformationszonen-Segmente einander gegenüber stärker verkippt werden können. Die seitliche Verschiebungsmöglichkeit des Steckbereiches gegenüber dem Lötbereich ist damit vergrößert.According to the invention, the openings have transverse slots and / or oblique slots and longitudinal slots running parallel to the longitudinal axis of the plug contact, and the transverse slots and / or oblique slots are connected at the ends to the longitudinal slots and preferably engage centrally in the longitudinal slots. The additional longitudinal slots further weaken the stiffness of the deformation zone. They are preferable designed to be much wider than the transverse and / or oblique slots. This significantly reduces the force required to deform the deformation zone. In addition, it is achieved that the deformation zones formed by the at least two transverse and / or oblique slots can be tilted more towards each other. The lateral displacement possibility of the plug-in area relative to the soldering area is thus increased.

Vorzugsweise sind die in axialer Richtung versetzt zueinander angeordneten Längsschlitze, die mit den Enden der Quer- und/oder Schrägschlitze verbunden sind, direkt übereinander angeordnet. Als besonders günstig hat sich bei allen Varianten mit mindestens zwei Quer- und/oder Schrägschlitzen herausgestellt, die Durchbrüche in Umfangsrichtung der Deformationszone jeweils rotationssymmetrisch versetzt zueinander anzuordnen, d.h. in Umfangsrichtung der Deformationszone gleichmäßig zu verteilen. Bei zwei Quer- und/oder Schrägschlitzen sind diese vorzugsweise um 180° in Umgangsrichtung versetzt zueinander an der Deformationszone angeordnet, bei einer anderen Anzahl von Quer- und/oder Schrägschlitzen um einen Winkel von 360°/Anzahl. Damit ist der Steckbereich gegenüber dem Lötbereich in allen Richtungen parallel zu der Leiterplatte in gleichem Maße verschiebbar.The longitudinal slots, which are offset in the axial direction relative to one another and are connected to the ends of the transverse and / or oblique slots, are preferably arranged directly above one another. In all variants with at least two transverse and / or oblique slots, it has proven to be particularly favorable to arrange the openings in the circumferential direction of the deformation zone in each case in a rotationally symmetrical offset from one another, ie. evenly distributed in the circumferential direction of the deformation zone. In the case of two transverse and / or oblique slots, these are preferably arranged offset by 180 ° in the direction of contact with each other at the deformation zone, with a different number of transverse and / or oblique slots by an angle of 360 ° / number. In order for the mating area relative to the soldering area in all directions parallel to the circuit board to the same extent displaceable.

In allen Ausführungsformen der Erfindung kann der vorgeschlagene elektrische Leiterplattenlötmontage-Steckverbinder bei einpoliger Ausführung einen Steckkontakt mit stiftförmigem oder buchsenförmigem Steckbereich und bei mehrpoliger Ausführung eine Anzahl von Steckkontakten mit stift- und/oder buchsenförmigen Steckbereichen nebeneinander aufweisen. Dabei können der Steckbereich, die Halte- und die Deformationszone des Zentralbereiches und der Lötbereich des jeweiligen Steckkontaktes in Größe und Form gleich und/oder unterschiedlich ausgebildet sein. Vorzugsweise weist bei all diesen Varianten zumindest der Zentralbereich mit der Deformationszone des mindestens einen Steckkontaktes plastisch verformbares Material auf.In all embodiments of the invention, the proposed electrical Leiterplattenlötmontage connector in unipolar design a plug contact with pin-shaped or socket-shaped plug-in area and multi-pole design a number of plug contacts with pin and / or socket-shaped plug-in areas next to each other. In this case, the plug-in area, the holding zone and the deformation zone of the central area and the soldering area of the respective plug-in contact can be identical in size and / or shape and / or different. Preferably, in all these variants, at least the central region with the deformation zone of the at least one plug-in contact plastically deformable material.

Der mindestens eine Steckkontakt ist einstückig hergestellt.The at least one plug contact is made in one piece.

Bei einem erfindungsgemäßen mehrpoligen elektrischen Leiterplattenlötmontage-Steckverbinder weisen alle Steckkontakte einen Zentralbereich mit einer Deformationszone mit den vorstehend beschriebenen Merkmalen auf. Die Steckkontakte bzw. die Deformationszonen sind dabei derart zueinander angeordnet, dass sie sich gegenseitig beim Ausrichten der Steckkontakte nicht im Wege stehen und auch nicht in Kontakt miteinander kommen. Die Ausrichtung der Steckkontakte zueinander und zu der Leiterplatte erfolgt sowohl bei einpoligen wie auch bei mehrpoligen Ausführungsformen indirekt über die Ausrichtung des Isolierkörpers des elektrischen Leiterplattenlötmontage-Steckverbinders gegenüber der Leiterplatte. Dabei kann der Isolierkörper im Bereich der Deformationszone und/oder im Lötbereich Zwischenwände aufweisen, die die Steckkontakte sicher elektrisch voneinander getrennt halten. Der Steckbereich ist ohnehin in der Aufnahmekammer elektrisch isoliert aufgenommen. Um einer unerwünschten Verformung des mindestens einen Steckkontaktes beim Ausrichten des vorgeschlagenen Leiterplattenlötmontage-Steckverbinders vorzubeugen und um eine unnötige Kraftbeaufschlagung des jeweiligen Lötpins bzw. Lötpads des Lötbereiches zu verhindern, weist die Deformationszone vorzugsweise eine deutliche geringere Biege- bzw. Knicksteifigkeit auf als die Haltezone des Zentralbereiches bzw. als der Lötbereich.In a multi-pole electrical Leiterplattenlötmontage connector according to the invention all the plug contacts have a central area with a deformation zone with the features described above. The plug contacts or the deformation zones are arranged relative to one another such that they do not stand in each other's way when aligning the plug contacts and also do not come into contact with each other. The alignment of the plug contacts to each other and to the circuit board takes place both in unipolar as well as multi-pole embodiments indirectly on the orientation of the insulating body of the electrical Leiterplattenlötmontage connector relative to the circuit board. In this case, the insulating body in the region of the deformation zone and / or in the soldering area have intermediate walls which hold the plug contacts safely separated electrically. The plug-in area is already electrically isolated in the receiving chamber. In order to prevent undesired deformation of the at least one plug contact during alignment of the proposed printed circuit board solder mounting connector and to prevent unnecessary application of force to the respective solder pin or solder pad of the soldering area, the deformation zone preferably has a significantly lower bending or buckling stiffness than the holding zone of the central area or as the soldering area.

Der mindestens eine Steckkontakt des erfindungsgemäßen Leiterplattenlötmontage-Steckverbinders ist insbesondere als Frästeil, als Drehteil oder als gerolltes Stanzbiegeteil hergestellt. Derartige Teile sind auf bekannte Weise kostengünstig herstellbar. Im Besonderen können bei gerollten Stanzbiege-Steckkontakten die Quer-, Schräg-, Längs- oder Spiralschlitze vor dem Rollen bereits beim Stanzen eingebracht werden. Dabei sind alle erdenklichen Geometrien und Anordnungsweisen möglich.The at least one plug-in contact of the printed circuit board solder-mounting connector according to the invention is produced in particular as a milled part, as a turned part or as a rolled stamped bent part. Such parts are inexpensive to produce in a known manner. In particular, with rolled stamped bending plug contacts, the transverse, oblique, longitudinal or spiral slots can already be introduced during punching before rolling. All conceivable geometries and arrangements are possible.

Die erfindungsgemäße elektrische Steckverbinderanordnung weist mindestens zwei an einer Leiterplatte angelötete elektrische Leiterplattenlötmontage-Steckverbinder gemäß einem der vorangegangenen Ansprüche auf. Bei einer Steckverbinderanordnung mit mindestens zwei derartigen an der Leiterplatte angelöteten Steckverbindern kommt der durch die besondere Ausgestaltung der Deformationszone des Zentralbereichs bewirkte Toleranzausgleich besonders zum Tragen.The electrical connector assembly according to the invention has at least two soldered to a circuit board electrical Leiterplattenlötmontage connector according to one of the preceding claims. In a connector assembly having at least two such soldered to the circuit board connectors which caused by the particular configuration of the deformation zone of the central region tolerance compensation comes particularly to fruition.

Die Figur 1 zeigt beispielhaft einen mehrpoligen erfindungsgemäßen Leiterplattenlötmontage-Steckverbinder 1 für eine in der Zeichnung nicht dargestellte Leiterplatte, in einer perspektivischen Längsschnittdarstellung. Der Leiterplattenlötmontage-Steckverbinder 1 weist einen Isolierkörper 2 und eine Anzahl von darin in Aufnahmekammern 3 aufgenommenen länglichen elektrischen Steckkontakten 4 auf, die sich zwischen einem der Leiterplatte zugeordneten Fußteil 5 und einem dem Fußteil 5 mit Abstand gegenüberliegenden Kopfteil 6 des Isolierkörpers 2 erstrecken. Die Steckkontakte 4 sind identisch ausgebildet und weisen an dem dem Kopfteil 6 nahen vorderen Ende 7 einen zugänglichen elektrisch kontaktierbaren Steckbereich 8, einen daran anschließenden Zentralbereich 9 und darauf folgend an einem dem Fußteil 5 nahen hinteren Ende 10 einen freiliegenden Lötbereich 11 auf. Der Zentralbereich 9 ist aufgeteilt in eine an den Steckbereich 8 anschließende zylinderförmige biegestarre Haltezone 12 und eine zwischen der Haltezone 12 und dem Lötbereich 11 erstreckende zylindrische nachgiebig ausgebildete Deformationszone 13. Damit ist der Steckbereich 8 der jeweiligen Steckkontakte 4 gegenüber dem Lötbereich 11 bei Deformierung der Deformationszone 13 bzw. der Isolierkörper 2 gegenüber der Leiterplatte seitlich verschiebbar.The FIG. 1 shows, by way of example, a multi-pole circuit board solder mounting connector 1 according to the invention for a printed circuit board, not shown in the drawing, in a perspective longitudinal section. The Leiterplattenlötmontage connector 1 has an insulator 2 and a number of therein received in receiving chambers 3 elongated electrical plug contacts 4, which is located between one of the circuit board associated foot part 5 and the foot part 5 at a distance opposite head portion 6 of the insulator 2 extend. The plug contacts 4 are of identical design and have at the head part 6 near the front end 7 an accessible electrically contactable plug-in area 8, an adjoining central area 9 and subsequently at a the foot part 5 near the rear end 10 an exposed soldering 11. The central region 9 is divided into a cylindrical bending-resistant holding zone 12 adjoining the plug-in region 8 and a cylindrical yielding deformation zone 13 extending between the holding zone 12 and the soldering region 11. Thus, the plug-in region 8 of the respective plug contacts 4 is opposite the soldering region 11 when the deformation zone is deformed 13 and the insulating body 2 relative to the circuit board laterally displaceable.

Die Haltezone 12 des Zentralbereiches 9 fixiert den Steckbereich 8 der Steckkontakte 4 seitlich unverrückbar in den Aufnahmekammern 3. Zwischen dem Isolierkörper 2 und den jeweiligen Steckkontakten 4 ist im Bereich der Deformationszonen 13 in den Aufnahmekammern 3 und/oder darunter je ein Ringspalt 14 ausgebildet. Damit können die Deformationszonen 13 bei seitlicher Kraftbeaufschlagung des Isolierkörpers 2 in die Ringspalte 14 hinein verformt werden. Die Steckkontakte 4 sind im Bereich der Deformationszone 13 innen hohl ausgebildet und weisen an den vorderen Enden 7 jeweils einen Steckbereich 8 mit angeformten Federzungen 15 auf. Für den erfindungsgemäßen Leiterplattenlötmontage-Steckverbinder 1 werden vorzugsweise gerollte als Stanzbiegeteile ausgeführte Steckkontakte 4 verwendet. Alle in den Ausführungsbeispiele dargestellten Varianten sind auch als Drehteile herstellbar. In der Figur 2 sind in den Figuren 2a und 2b exemplarisch zwei verschiedene derartige Steckkontakte 4, jeweils in zwei Ansichten, dargestellt.The holding zone 12 of the central region 9 fixes the plug-in region 8 of the plug contacts 4 laterally immovable in the receiving chambers 3. Between the insulating body 2 and the respective plug contacts 4 in the region of the deformation zones 13 in the receiving chambers 3 and / or below each an annular gap 14 is formed. Thus, the deformation zones 13 can be deformed in lateral force application of the insulating body 2 in the annular gaps 14 in. The plug contacts 4 are formed hollow in the region of the deformation zone 13 inside and have at the front ends 7 in each case a plug-in area 8 with integrally formed spring tongues 15. For the printed circuit board solder-mounting connector 1 according to the invention, preferably rolled plug-in contacts 4 designed as stamped and bent parts are used. All variants shown in the embodiments can also be produced as turned parts. In the FIG. 2 are in the FIGS. 2a and 2b two different such plug contacts 4, in each case in two views, shown by way of example.

Die in den Figuren 2a, 2b verbildlichten Ausführungsformen des Steckkontakts 4 sind zuerst aus einem Materialstreifen ausgestanzt und dann gerollt. Die Steckkontakte 4 sind einstückig aus einem plastisch verformbaren Material hergestellt. Die Materialstärke des verwendeten Materialstreifens beträgt dabei typisch zwischen 0,25 und 0,4 mm. Bei einer beispielhaften Höhe von 5 mm und einem entsprechenden Durchmesser von etwa 1,5 mm der Deformationszone 13 lässt sich der Steckbereich 8 gegenüber dem Lötbereich 11 durch Biegen oder Knicken der Deformationszone 13 in mindestens zwei Richtungen in etwa um 0,35 mm seitlich verschieben.The in the FIGS. 2a, 2b Illustrated embodiments of the plug-in contact 4 are first punched out of a strip of material and then rolled. The plug contacts 4 are made in one piece from a plastically deformable material. The material thickness of the material strip used is typically between 0.25 and 0.4 mm. At an exemplary height of 5 mm and a corresponding diameter of about 1.5 mm of the deformation zone 13 can be the plug-in area 8 relative to the soldering 11 by bending or buckling of the deformation zone 13 in at least two directions in about 0.35 mm laterally move.

Die in den Figuren 2a, 2b gezeigten Varianten des Steckkontakts 4 weisen eine Deformationszone 13 mit zwei quer zu der Längsachse des Steckkontakts 4 verlaufenden, in axialer Richtung versetzt zueinander angeordneten Durchbrüchen 16 auf. Die Durchbrüche 16 erstrecken sich jeweils in einer Ebene über die Hälfte der Umfangswand 18 der Deformationszone 13 hinaus. Die Durchbrüche 16 unterteilen die Deformationszone 13 in einzelne Deformationszonen-Segmente 17, die nur noch über einen Teil der Umfangswand 18 des Zentralbereiches 9 miteinander und/oder der Haltezone 12 mit dem daran anschließenden Steckbereich 8 bzw. mit dem Lötbereich 11 verbunden sind. Die Deformationszonen-Segmente 17 sind in den Figuren 3, 4 mit Bezugsziffern ausgewiesen. Die Verbindungsstellen dieser Deformationszonen-Segmente 17 sind besonders nachgiebig. Sie ermöglichen ein seitliches Verkippen der Deformationszonen-Segmente einander gegenüber, wobei sich die Größe und die Form der Durchbrüche 16 verändert.The in the FIGS. 2a, 2b shown variants of the plug-in contact 4 have a deformation zone 13 with two transverse to the longitudinal axis of the plug-in contact 4 extending, offset in the axial direction to each other arranged openings 16. The apertures 16 each extend in a plane over half of the peripheral wall 18 of the deformation zone 13 also. The apertures 16 subdivide the deformation zone 13 into individual deformation zone segments 17, which are connected to each other only over part of the peripheral wall 18 of the central region 9 and / or the holding zone 12 to the adjoining plug region 8 or to the solder region 11. The deformation zone segments 17 are in the Figures 3 . 4 indicated by reference numbers. The joints of these deformation zone segments 17 are particularly resilient. They allow a lateral tilting of the deformation zone segments opposite each other, wherein the size and shape of the apertures 16 changes.

Bei den in den Figuren 2a, 2b abgebildeten Steckkontakten 4 mit rohförmiger Deformationszone 13 sind die Durchbrüche 16 als Schlitze ausgebildet. Die Deformationszonen 13 der in den Figuren 2a, 2b visualisierten Steckkontakte 4 weisen demnach Querschlitze 19 auf, die in axialer Richtung des Zentralbereiches 9 versetzt zueinander angeordnet sind. Zusätzlich zu den Querschlitzen 19 sind bei diesen Varianten mehrere parallel zu der Längsachse des Steckkontaktes 4 verlaufende Längsschlitze 20 angeordnet, wobei die Querschlitze 19 endseitig mit den Längsschlitzen 20 verbunden sind und in die Längsschlitze 20 mittig eingreifen. Dabei sind die Längsschlitze 20 wesentlich breiter ausgebildet als die Querschlitze 19. Gemäß der Figur 2a sind die beiden den Querschlitzen 19 jeweils zugeordneten Längsschlitze 20 übereinander in Umfangsrichtung versetzt zueinander angeordnet. In der in der Figur 2b dargestellten Variante sind diese Längsschlitze 20 direkt übereinander angeordnet. Vorteilhafterweise sind bei allen in der Figur 2 dargestellten Ausführungsformen der Steckkontakte 4 die Durchbrüche 16, d.h. insbesondere die Querschlitze 19 und/oder die Schrägschlitze rotationssymmetrisch um die Mittelachse der Deformationszone 13 versetzt zueinander angeordnet.In the in the FIGS. 2a, 2b Pictured plug contacts 4 with a raw deformation zone 13, the openings 16 are formed as slots. The deformation zones 13 in the FIGS. 2a, 2b visualized plug contacts 4 thus have transverse slots 19 which are arranged offset in the axial direction of the central region 9 to each other. In addition to the transverse slots 19, a plurality of longitudinal slots 20 extending parallel to the longitudinal axis of the plug contact 4 are arranged in these variants, wherein the transverse slots 19 are connected at the end to the longitudinal slots 20 and engage centrally in the longitudinal slots 20. The longitudinal slots 20 are substantially wider than the transverse slots 19. According to the FIG. 2a are the two transverse slots 19 respectively associated longitudinal slots 20 one above the other in the circumferential direction offset from each other. In the in the FIG. 2b variant shown are these longitudinal slots 20 are arranged directly above one another. Advantageously, in all in the FIG. 2 illustrated embodiments of the plug contacts 4, the apertures 16, ie in particular the transverse slots 19 and / or the slanted slots rotationally symmetrical about the central axis of the deformation zone 13 offset from one another.

Die Figuren 3a, 3b zeigen die Abwicklung der Steckkontakte aus Figur 2a und 2b. Dort sind die Durchbrüche 16 in Größe, Form, Anordnung und Verlauf in der Deformationszone 13 deutlich erkennbar. Außerdem sind die Lage- und Größenverhältnisse des Steckbereichs 8, des Zentralbereichs 9 und des Lötbereichs 11 einander gegenüber ersichtlich, insbesondere auch die der Deformationszone 13.The FIGS. 3a, 3b show the handling of the plug contacts FIGS. 2a and 2b , There, the openings 16 in size, shape, arrangement and course in the deformation zone 13 are clearly visible. In addition, the position and size relationships of the plug-in region 8, the central region 9 and the soldering region 11 are opposite one another, in particular also that of the deformation zone 13.

Die Figuren 4a und 4b zeigen Ausschnittsvergrößerungen einer verformten Deformationszone 13 der Steckkontakte 4 gemäß den Figuren 2a, 2b. Dort ist deutlich zu erkennen, dass die jeweils drei Deformationszonen-Segmente 17 gegeneinander verkippt sind, wobei die beiden äußeren Deformationszonen-Segmente 17 parallel zueinander ausgerichtet sind. Damit weist der Steckbereich 8 einen seitlichen Versatz gegenüber dem Lötbereich 11 auf. Dabei ist deutlich zu erkennen, dass die Durchbrüche 16 in Form von Querschlitzen 19, Schrägschlitzen und/oder Längsschlitzen 20 gegenüber der in den Figuren 2 und 3 dargestellten ursprünglichen Form deutlich verändert sind.The FIGS. 4a and 4b show enlarged detail of a deformed deformation zone 13 of the plug contacts 4 according to the FIGS. 2a, 2b , It can clearly be seen there that the respective three deformation zone segments 17 are tilted relative to one another, wherein the two outer deformation zone segments 17 are aligned parallel to one another. Thus, the plug-in area 8 has a lateral offset relative to the soldering area 11. It can be clearly seen that the openings 16 in the form of transverse slots 19, slanted slots and / or longitudinal slots 20 with respect to in the Figures 2 and 3 shown in the original form are clearly changed.
