Description

Die Erfindung betrifft einen elektrischen Steckverbinder, mit einem Isolierkörper, in dem mindestens ein metallisches Steckkontaktteil aufgenommen ist, das mindestens ein Lötanschlusselement, das mit einer Leiterplatte verlötbar ist, und mindestens ein Steckanschlusselement für ein Gegensteckkontaktteil aufweist, wobei zumindest das Lötanschlusselement über den Isolierkörper mindestens teilweise vorsteht, sowie eine Steckverbinderanordnung.The invention relates to an electrical connector, comprising an insulating body, in which at least one metallic plug contact part is accommodated, which has at least one solder connection element which can be soldered to a printed circuit board, and at least one plug connection element for a mating plug contact part, wherein at least the solder connection element at least partially over the insulating body protrudes, as well as a connector assembly.

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 Steckkontaktteile nach dem Verlöten mit der Leiterplatte problemlos in einer toleranzbehafteten Aufnahme angeordnet werden können. Dieses Problem tritt insbesondere dann auf, wenn der zu verlötende Steckverbinder eine große Anzahl von Steckkontaktteilen 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 Steckkontaktteile und damit auch der die Steckkontaktteile 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 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.A problem with electrical connectors is to provide pluggable female and male connectors, of which at least one connector is to be soldered to a printed circuit board, which despite some misalignment of some or all of the female or pin shaped male contact parts after soldering the circuit board can be easily arranged in a tolerance-sensitive recording. This problem occurs in particular when the connector to be soldered has a large number of plug contact parts or if several socket and / or pin connectors are arranged side by side on a circuit board and the electrical connection is to be made via a common group connector in a tolerance-sensitive recording , The occurring offset of the individual plug contact parts and thus also the plug contact parts receiving insulator is due to 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 component electrical 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 Steckkontaktteile 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 Steckkontaktteile wird dabei jedoch nicht korrigiert, so dass die Gegensteckkontaktteile des Gegensteckverbinders nur schwer mit den Steckkontaktteilen des bzw. der verlöteten Steckverbinder verbindbar sind und die Lötstelle der Steckkontaktteile mit Kraft beaufschlagen. Dies kann auf Dauer zur Schädigung der Lötstellen führen. Außerdem können die Steckkontaktteile des mindestens einen aufgelöteten Steckverbinders und/oder die Gegensteckkontaktteile des Gegensteckverbinders beschädigt eventuell sogar unbrauchbar werden.To solve the problem, it is known to receive the plug contact parts floating in the respective insulating. 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 contact parts is not corrected, so that the mating plug contact parts of the mating connector are difficult to connect to the plug contact parts of the soldered or connectors and act on the solder joint of the plug contact parts with force. This can permanently lead to damage to the solder joints. In addition, the plug contact parts of the at least one soldered connector and / or the mating plug contact parts of the mating connector may possibly even become unusable.

Ausgehend von dem vorstehend beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit für einen Toleranzausgleich zwischen mit einer Leiterplatte verlöteten Steckkontaktteilen mindestens eines 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 present invention seeks to propose a way for a tolerance compensation between soldered to a circuit board plug contact parts at least one connector and a receptacle for the or the insulator, in / which are included the metallic plug contact parts ,

Weitere vorteilhafte Ausführungsformen sind den rückbezogenen Ansprüchen zu entnehmen. 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 connector with the features of claim 1. Further advantageous embodiments can be found in the dependent claims. 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 erfindungsgemäßen elektrischen Steckverbinder ist das Steckanschlusselement direkt oder indirekt mit dem Lötanschlusselement über ein Toleranzausgleichsstück derart verbunden, dass die Position des Steckanschlusselements gegenüber der Position des Lötanschlusselementes, bei mit der Leiterplatte verlöteten Lötanschlusselement, parallel zu der Ebene der Leiterplatte in alle Richtungen veränderbar ist. Dabei kann das Steckkontaktteil einstückig oder mehrstückig ausgebildet sein. Bei mehrstückiger Ausbildung können die Einzelteile durch geeignete dem Fachmann bekannte Verbindungsverfahren mechanisch und elektrisch miteinander verbunden werden. Bei einstückiger Ausbildung des Steckkontaktteils wird das Toleranzausgleichsstück im Bereich eines das Steck-und das Lötanschlusselement verbindenden Mittelstückes an einer brauchbaren Stelle angeformt. Bei mehrstückiger Ausbildung des Steckkontaktteils wird es integral mit dem Steckanschlusselement oder dem Lötanschlusselement des mindestens einen Steckkontaktteils ausgebildet. Idealerweise wird das Toleranzausgleichsstück gegenüber dem Mittelstück, dem Steckanschlusselement und/oder dem Lötanschlusselement geometrisch derart gestaltet, das es gegenüber diesen mit geringerem Kraftaufwand verformbar ist.In the electrical connector according to the invention, the plug connection element is directly or indirectly connected to the Lötanschlusselement via a tolerance compensation piece such that the position of the plug connection element relative to the position of the Lötanschlusselementes, soldered to the circuit board solder connection element, is parallel to the plane of the circuit board in all directions changeable. In this case, the plug contact part may be formed integrally or in several pieces. In the case of multi-part design, the individual parts can be mechanically and electrically connected to one another by suitable joining methods known to the person skilled in the art. In one-piece design of the plug-in contact part, the tolerance compensation piece in the region of a connecting piece and the Lötanschlusselement connecting central piece is formed at a useful point. In multi-piece design of the plug contact part, it is formed integrally with the plug connection element or the solder connection element of the at least one plug contact part. Ideally, the tolerance compensation piece with respect to the center piece, the plug connection element and / or the Lötanschlusselement geometrically designed so that it is deformable with respect to these with less effort.

Vorzugsweise weist das Toleranzausgleichsstück eine S-förmige, U-förmige, kreisförmige, spiralförmige oder wellenförmige Kontur auf. Die Erfindung ist jedoch nicht auf die genannten Konturen beschränkt. Wesentlich ist, dass die bevorzugten Konturen es ermöglichen mit geringem Kraftaufwand eine Verschiebung des Steckanschlusselementes gegenüber dem Lötanschlusselement in eine beliebige Raumrichtungen parallel zu der Leiterplatte, mit der der mindestens eine Steckverbinder verlötet ist, zu bewirken.The tolerance compensation piece preferably has an S-shaped, U-shaped, circular, spiral or wavy contour. However, the invention is not limited to the contours mentioned. It is essential that the preferred contours make it possible with little effort to effect a displacement of the plug connection element with respect to the solder connection element in any desired spatial directions parallel to the circuit board with which the at least one plug connector is soldered.

Bei bevorzugten Ausführungsformen der Erfindung ist das Steckkontaktteil zweistückig ausgebildet, wobei das Steckanschlusselement und das Toleranzausgleichsstück miteinander kraft- oder stoffschlüssig verbunden sind. Das Toleranzausgleichsstück erstreckt sich dabei, mit oder ohne Vorspannung, senkrecht zu der Ebene der Leiterplatte geradlinig und in Erstreckungsrichtung der Leiterplatte gebogen. Es ist flexibel, d.h. verformbar ausgebildet und kann durch eine geringe parallel zu der Ebene der Leiterplatte wirkende Kraft reversibel oder irreversibel verbogen werden. Dazu ist das Lötanschlusselement aus einem streifenförmigen Material herausgeschnitten oder herausgestanzt. Es ist mit dem Steckanschlusselement derart verbunden, dass die Flachseiten des Toleranzausgleichsstückes bei mit der Leiterplatte verlöteten Steckverbinder stehend zu der Ebene der Leiterplatte angeordnet sind. In dieser Ebene können sich auch für die Durchsteckmontage vorgesehene angeformte Lötpins des Lötanschlusselementes erstrecken. Alternativ können sich senkrecht zu dieser Ebene für die Oberflächenmontage ausgebildete abgewinkelt angeformte Lötpads des Lötanschlusselements erstrecken.In preferred embodiments of the invention, the plug contact part is formed in two pieces, wherein the plug connection element and the tolerance compensation piece are positively or materially connected to each other. The tolerance compensation piece extends, with or without bias, perpendicular to the plane of the circuit board straight and bent in the direction of extension of the circuit board. It is flexible, ie formed deformable and can by a small force acting parallel to the plane of the circuit board is reversibly or irreversibly bent. For this purpose, the Lötanschlusselement is cut out of a strip-shaped material or punched out. It is connected to the plug-in connection element in such a way that the flat sides of the tolerance compensating piece are arranged, when the plug-in connector is soldered to the printed circuit board, upright relative to the plane of the printed circuit board. In this plane, provided for through-hole mounting molded solder pins of Lötanschlusselementes can extend. Alternatively, orthogonally formed solder pads of the solder connection element may be formed perpendicularly to this plane for surface mounting.

Bei dem erfindungsgemäßen elektrischen Steckverbinder weisen alle Steckkontaktteile an ihren Lötanschlusselementen ein derartiges Toleranzausgleichsstück auf. Die Toleranzausgleichsstücke sind dabei derart zueinander angeordnet, dass sie sich gegenseitig beim Ausrichten der Steckanschlusselemente nicht im Wege stehen und auch nicht in Kontakt miteinander kommen. Die Ausrichtung der Steckkontaktteile zueinander erfolgt indirekt über die Ausrichtung des Isolierkörpers des elektrischen Steckverbinders. Dabei kann der Isolierkörper im Bereich der Toleranzausgleichsstücke Zwischenwände aufweisen, die die Toleranzausgleichsstücke sicher elektrisch voneinander getrennt halten. Um einer unerwünschten Verformung des mindestens einen Steckanschlusselementes beim Ausrichten des vorgeschlagenen Steckverbinders vorzubeugen und um eine unnötige Kraftbeaufschlagung des jeweiligen Lötpins bzw. Lötpads zu verhindern, weist das Toleranzausgleichsstück eine vorzugsweise deutlich geringere Biegesteifigkeit als das Steckanschlusselement und die Lötpins bzw. die Lötpads des Lötanschlusselements auf.In the electrical connector according to the invention, all plug contact parts on their Lötanschlusselementen such a tolerance compensating piece. The tolerance compensating pieces are arranged in such a way to each other that they do not interfere with each other when aligning the plug connection elements and also do not come into contact with each other. The alignment of the plug contact parts to each other takes place indirectly via the orientation of the insulating body of the electrical connector. In this case, the insulating body in the region of the tolerance compensating pieces have intermediate walls which hold the tolerance compensating pieces safely separated from each other electrically. In order to prevent unwanted deformation of the at least one plug-in connection element during alignment of the proposed connector and to prevent unnecessary application of force to the respective solder pin or solder pad, the tolerance compensation piece has a preferably significantly lower flexural rigidity than the plug connection element and the solder pins or solder pads of the solder connection element.

Der vorgeschlagene elektrische Steckverbinder kann entweder nur stiftförmige, nur buchsenförmige oder stift- und buchsenförmige Steckkontaktteile nebeneinander angeordnet aufweisen. Dabei können die Steckanschlusselemente und/oder die Lötanschlusselemente der buchsenförmigen oder stiftförmigen Steckkontaktteile in Größe und Form gleich oder unterschiedlich ausgebildet sein.The proposed electrical connector can either only pin-shaped, only socket-shaped or pin and socket-shaped plug contact parts arranged side by side. In this case, the plug-in connection elements and / or the solder connection elements of the socket-shaped or pin-shaped plug contact parts may be the same or different in size and shape.

Dies gilt gleichermaßen für die Toleranzausgleichsstücke der Lötanschlusselemente.This applies equally to the tolerance compensating pieces of Lötanschlusselemente.

Das Lötanschlusselement und das Steckanschlusselement des erfindungsgemäßen Steckverbinders können entweder nur über das Toleranzausgleichsstück oder beispielsweise über ein zusätzliches Mittelstück und das Toleranzausgleichsstück mechanisch und elektrisch leitend miteinander verbunden sein. Dies kann mittels verschiedenen bekannten Maßnahmen erfolgen. Bevorzugt wird eine Ausführungsform der Erfindung, bei der das Toleranzausgleichsstück mit dem Steckanschlusselement direkt oder dem Mittelstück verschweißt, vorzugsweise punktverschweißt ist. Damit wird eine dauerhaft sichere Verbindung hergestellt, die zudem elektrisch äußerst niederohmig ist.The solder connection element and the plug connection element of the connector according to the invention can be connected to one another mechanically or electrically conductively either only via the tolerance compensation piece or, for example, via an additional middle piece and the tolerance compensation piece. This can be done by means of various known measures. An embodiment of the invention in which the tolerance compensation piece is welded to the plug connection element directly or to the middle piece is preferably spot welded. This creates a permanently secure connection, which is also electrically extremely low impedance.

Die Verformbarkeit des Toleranzausgleichsstückes ist nicht nur abhängig von der gewählten Geometrie für das Toleranzausgleichsstück, sondern auch von der Materialstärke des Materials, aus dem das Toleranzausgleichstück mit dem daran angeformten Lötanschlusselement hergestellt ist, sowie auch von den speziellen Materialeigenschaften dieses Materials. Bei einer begünstigten Variante des erfindungsgemäßen Steckverbinders weist das Toleranzausgleichsstück bzw. das Lötanschlusselement ein Material auf, das in den Materialeigenschaften und/oder der Materialstärke von dem Material für das Mittelstück mit dem daran angeformtem Steckanschlusselement bzw. dem Steckanschlusselement abweicht. So kann für die speziellen Funktionen dieser Teile jeweils ein spezielles geeignetes Material verwendet werden, ohne dass Kompromisse notwendig sind.The deformability of the tolerance compensation piece depends not only on the geometry selected for the tolerance compensation piece, but also on the material thickness of the material from which the tolerance compensation piece is made with the solder connection element formed thereon, as well as on the special material properties of this material. In a preferred variant of the connector according to the invention, the tolerance compensation piece or the solder connection element has a material which deviates in material properties and / or material thickness from the material for the center piece with the plug connection element or the plug connection element formed thereon. Thus, a specific suitable material can be used for the specific functions of these parts, without compromises being necessary.

Als Material für das Steckanschlusselement wird zweckmäßigerweise ein elastisch verformbares Material und für das Lötanschlusselement vorzugsweise ein plastisch verformbares Material jeweils geeigneter Stärke verwendet. Damit ist auch das Toleranzausgleichsstück in Verbindung mit einer günstigen Geometrie, wie vorstehend beschrieben, leicht plastisch verformbar, so dass die Ausrichtung des Isolierkörpers mit den darin aufgenommenen Steckkontaktteilen gegenüber der Leiterplatte bleibend ist. Zudem verhindert die plastische Verformung des jeweiligen Toleranzausgleichsstücks, dass dauerhaft eine Kraft auf die Lötstellen des erfindungsgemäßen elektrischen Steckverbinders und das Kunststoffmaterial des Isolierkörpers ausgeübt wird.The material used for the plug-in connection element is expediently an elastically deformable material and, for the solder connection element, preferably a plastically deformable material of suitable strength in each case. Thus, the tolerance compensating piece in connection with a favorable geometry, as described above, easily plastically deformable, so that the orientation of the insulating body with the therein recorded plug contact parts with respect to the circuit board is permanent. In addition, the plastic deformation of the respective tolerance compensation piece prevents permanently a force on the solder joints the electrical connector according to the invention and the plastic material of the insulating body is exercised.

Vorzugsweise ist zumindest das Toleranzausgleichsstück mit dem daran angeformten Lötanschlusselement ein Stanzbiegeteil, das auf bekannte Weise kostengünstig herstellbar ist. Dabei kann das Lötanschlusselement Lötpins oder Lötpads aufweisen, die einfach integral mit dem und angeformt an das Toleranzausgleichsstück ausgebildet sind.Preferably, at least the tolerance compensating piece with the solder connection element formed thereon is a stamped and bent part which can be produced cost-effectively in a known manner. In this case, the solder connection element soldering pins or solder pads have, which are simply integrally formed with and integrally formed on the tolerance compensation piece.

Bei einer Steckverbinderanordnung mit mindestens zwei an einer Leiterplatte angelöteten vorstehend beschriebenen Steckverbindern kommt der durch die besondere Ausgestaltung bewirkte Toleranzausgleich besonders zu tragen.In a connector assembly having at least two soldered to a circuit board described above connectors caused by the particular design tolerance compensation is particularly borne.

Die Figur 1 zeigt beispielhaft eine Steckverbinderanordnung mit nur zwei nebeneinander auf einer Leiterplatte 1 angeordneten erfindungsgemäßen elektrischen Steckverbindern 2, die nebeneinander mit Abstand zueinander mit der Leiterplatte 1, in der Zeichnung nicht sichtbar, verlötet sind. Die Steckverbinder 2 sind als oberflächenmontierbare Bauteile ausgebildet. Oberhalb der Leiterplatte 1 mit den Steckverbindern 2 ist eine Aufnahme 3 abgebildet, durch die die Steckverbinder 2 hindurchtreten sollen. Die Aufnahme kann beispielsweise ein Flansch sein, mit dem die Steckverbinder 2 mit Leiterplatte 1 an einem Gehäuse befestigt werden, oder direkt eine Gehäusewand eines die Steckverbinder 2, die Leiterplatte 1 und eventuell noch weitere Elemente aufnehmenden Gehäuses. Die Steckverbinder 2 weisen einen zylindrischen Isolierkörper 4 mit vier darin aufgenommenen Steckkontaktteilen 5 auf. Die Steckkontaktteile 5 sind bei dem in Längsrichtung geschnitten dargestellten linken Steckverbinder 2 sichtbar.The FIG. 1 shows by way of example a connector assembly with only two juxtaposed on a circuit board 1 arranged according to the invention electrical connectors 2, which are next to each other at a distance from each other with the circuit board 1, not visible in the drawing soldered. The connectors 2 are formed as surface mountable components. Above the circuit board 1 with the connectors 2, a receptacle 3 is shown, through which the connector 2 should pass. The receptacle can be, for example, a flange with which the plug-in connectors 2 with printed circuit board 1 are fastened to a housing, or directly a housing wall of a housing receiving the plug-in connectors 2, the printed circuit board 1 and possibly further elements. The plug connectors 2 have a cylindrical insulating body 4 with four plug contact parts 5 received therein. The plug-in contact parts 5 are visible in the longitudinal connector shown left connector 2.

Die Steckkontaktteile 5 weisen Steckanschlusselemente 6 und Lötanschlusselemente 15 (Lötpin oder Lötpad; hier Lötpad) auf. Die Steckanschlusselemente 6 sind in dem Ausführungsbeispiel als Buchsen ausgebildet und erstrecken sich in Längsrichtung des Isolierkörpers 4 und senkrecht zu der Leiterplatte 1. Zwischen den Steckanschlusselementen 6 und dem Lötanschlusselement 15 befinden sich Toleranzausgleichsstücke 7 mit einem gebogenen Bereich 9. Die Toleranzausgleichsstücke 7 sind quer zu den Steckanschlusselementen 6 angeordnet und verlaufen aufrecht stehend radial zu den Steckanschlusselementen 6 parallel zu der Leiterplatte 1. In dem Ausführungsbeispiel weisen die Steckanschlusselemente 6 Mittelstücke 8 auf, die mit dem Toleranzausgleichsstück 7 durch Verschweißen stoffschlüssig verbunden sind. Das jeweilige Toleranzausgleichsstück 7 der Steckkontaktteile 5 ist parallel zu der Ebene der Leiterplatte 1 im Bereich 9 in alle Richtungen verformbar.The plug contact parts 5 have plug connection elements 6 and solder connection elements 15 (solder pin or solder pad, here solder pad). The plug connection elements 6 are formed in the embodiment as sockets and extend in the longitudinal direction of the insulating body 4 and perpendicular to the circuit board 1. Between the plug connection elements 6 and the solder connection element 15 are tolerance compensating pieces 7 with a bent portion 9. The tolerance compensating pieces 7 are transverse to the Plug connection elements 6 are arranged and extend upright radially to the plug-in connection elements 6 parallel to the printed circuit board 1. In the exemplary embodiment, the plug-in connection elements 6 centerpieces 8, which are materially connected by welding with the tolerance compensation piece 7. The respective tolerance compensation piece 7 of the plug contact parts 5 is parallel to the plane of the circuit board 1 in the area 9 in all directions deformable.

In den Figuren 2a, 2b ist einer der Steckverbinder 2 aus der Figur 1, die identisch ausgeführt sind, mit Blick schräg von unten auf den Boden 10 des Isolierkörpers 4 des Steckverbinders 2 abgebildet. Die Figuren 2a, 2b zeigen den Steckverbinder 2 dabei aus unterschiedlichen Blickrichtungen. Es ist deutlich zu sehen, dass die vier Mittelstücke 8 aus dem Boden 10 hervortreten und sich die daran angeschweißten Toleranzausgleichsstücke 7 quer zu diesen erstrecken. Die Steckanschlusselemente 6, die Lötanschlusselemente 15, die Mittelstücke 8 und die Toleranzausgleichstücke 7 sind jeweils als Stanzbiegeteile aus einem schmalen Materialstreifen hergestellt und durch Biegen speziell geformt. Die Toleranzausgleichsstücke 7 sind bei diesem Ausführungsbeispiel unterschiedlich in der Form ausgebildet, was jedoch nicht unbedingt so sein muss. Die Materialhöhe eines solchen Toleranzausgleichstückes 7 mit angeformtem Lötanschlusselement 15 beträgt etwa 1 bis 2 mm, die Materialstärke etwa 0,2 bis 0,3 mm. Dabei handelt es sich um typische Werte, die jedoch auch anders gewählt werden können.In the FIGS. 2a . 2 B is one of the connectors 2 from the FIG. 1 , which are identical, with view obliquely from below on the bottom 10 of the insulator 4 of the connector 2 shown. The FIGS. 2a . 2 B show the connector 2 while from different directions. It is clear to see that the four middle pieces 8 emerge from the bottom 10 and the tolerance compensating pieces 7 welded thereto extend transversely thereto. The plug-in connection elements 6, the solder connection elements 15, the middle pieces 8 and the tolerance compensation pieces 7 are each manufactured as stamped and bent parts from a narrow strip of material and specially shaped by bending. The tolerance compensating pieces 7 are formed differently in shape in this embodiment, but not necessarily so. The material height of such a tolerance compensation piece 7 with molded Lötanschlusselement 15 is about 1 to 2 mm, the material thickness about 0.2 to 0.3 mm. These are typical values, but they can be chosen differently.

Wie aus den Figuren 2a, 2b zu entnehmen ist, weisen die Toleranzausgleichsstücke 7 quer zu der Ebene der Leiterplatte 1 und zu der Mittelachse des Isolierkörpers 4 eine unterschiedliche und komplexe Form auf. Sie sind in dem Bereich 9 verschieden kreis- bzw. spiralförmig oder wellenförmig gebogen. Damit können die Toleranzausgleichsstücke 7 parallel zu der Ebene der Leiterplatte 1 um ein konstruktiv vorgegebenes Maß durch Biegen verformt werden, um den erfindungsgemäßen elektrischen Steckverbinder 2 gegenüber der Leiterplatte 1 auszurichten. Dies ist notwendig, falls die jeweiligen Isolierkörper 4 mit den darin gehaltenen Steckkontaktteilen 5 nicht mit den Durchbrüchen 11 der Aufnahme 3 exakt fluchten, wenn die Aufnahme 3 den Steckverbinder 2 über- und umgreifend in Richtung der Leiterplatte 1, wie in der Figur 1 dargestellt, abgesenkt werden soll.Like from the FIGS. 2a . 2 B can be seen, the tolerance compensating pieces 7 transverse to the plane of the circuit board 1 and to the central axis of the insulating body 4 a different and complex shape. They are bent in the area 9 different circular or spiral or wavy. Thus, the tolerance compensating pieces 7 can be deformed parallel to the plane of the circuit board 1 by a structurally predetermined amount by bending to align the electrical connector 2 according to the invention with respect to the circuit board 1. This is necessary if the respective insulator 4 with the therein held plug contact parts 5 are not exactly aligned with the apertures 11 of the receptacle 3 when the receptacle 3 over the connector 2 and embracing in the direction of the circuit board 1, as in the FIG. 1 shown, to be lowered.

Die Figur 3 zeigt den vorgeschlagenen Steckverbinder 2 in Draufsicht auf den Boden 10 des Isolierkörpers 4. In dieser Darstellung ist die unterschiedliche Form der Toleranzausgleichsstücke 7 nochmals verdeutlicht. Die Toleranzausgleichsstücke 7 erstrecken sich jeweils radial zu dem Isolierkörper 2. Dabei ist die Form der Toleranzausgleichsstücke 7 derart gewählt, dass der Isolierkörper 4 parallel zu seiner Mittelachse 12 und zu der Ebene der nicht dargestellten Leiterplatte 1 in eine beliebige Richtung translatorisch bewegt werden kann. Gleichzeitig ist eine rotatorische Bewegung des Isolierkörpers 4 um dessen Mittelachse 12 möglich.The FIG. 3 shows the proposed connector 2 in plan view of the bottom 10 of the insulator 4. In this illustration, the different shape of the tolerance compensating pieces 7 is again illustrated. The tolerance compensating pieces 7 each extend radially to the insulating body 2. The shape of the tolerance compensating pieces 7 is selected such that the insulating body 4 can be moved in translation parallel to its central axis 12 and to the plane of the printed circuit board 1, not shown in any direction. At the same time, a rotational movement of the insulating body 4 about the central axis 12 is possible.

Somit ist der erfindungsgemäße elektrische Steckverbinder 2 unter unterschiedlicher Verformung der Toleranzausgleichsstücke 7 der Steckkontaktteile 5 reversibel oder irreversibel exakt gegenüber der Leiterplatte 1 und der Leitenplattenabdeckung 3 ausrichtbar.Thus, the electrical connector 2 according to the invention under different deformation of the tolerance compensating pieces 7 of the plug contact parts 5 reversibly or irreversibly exactly relative to the circuit board 1 and the Leitenplattenabdeckung 3 aligned.

Die Figuren 4a bis 4d zeigen den in dem Ausführungsbeispiel der Erfindung dargestellten Steckverbinder 2, mit jeweils einem in den Isolierkörper 4 noch nicht axial eingeführten Steckkontaktteil 5. Deutlich ist jetzt die Aufnahmekammer 13 zu sehen, in der sich das Steckanschlusselement 6 automatisch verrastet, sobald es vollständig eingeführt ist. Die Steckanschlusselemente 6 sind gemäß den Figuren 4a bis 4d alle gleich und in der Form hohlzylindrisch mit Federkontaktzungen 14 ausgebildet. Es ist auch klar zu erkennen, dass die Steckkontaktteile 5 jeweils zweistückig ausgebildet sind und dass die Mittelstücke 8 mit den Steckanschlusselementen 6 und die Toleranzausgleichstücke 7 mit den Lötanschlusselementen 15 quer zueinander miteinander verbunden sind. Auch die unterschiedliche Form der Toleranzausgleichstücke 7 mit den Lötpads 15 und den unterschiedlich großen und verschieden geformten Bereichen 9 wird in der Gegenüberstellung nochmals klar herausgestellt.The FIGS. 4a to 4d show the connector 2 shown in the embodiment of the invention, each with a not yet axially inserted into the insulating body 4 plug contact part 5. Clearly now the receiving chamber 13 can be seen in which the plug connection element 6 automatically locked when it is fully inserted. The plug connection elements 6 are in accordance with FIGS. 4a to 4d all the same and in the form of a hollow cylinder formed with spring contact tongues 14. It can also be clearly seen that the plug contact parts 5 are each formed in two pieces and that the middle pieces 8 are connected to the plug connection elements 6 and the tolerance compensating pieces 7 with the solder connection elements 15 transversely to each other. The different shape of the tolerance compensating pieces 7 with the soldering pads 15 and the different sized and differently shaped areas 9 is again clearly highlighted in the comparison.

In der Regel weisen Steckkontaktteile eines elektrischen Steckverbinders jeweils nur ein Steckanschlusselement mit einem Stift bzw. einer Buchse und ein Lötanschlusselement mit einem Lötpin bzw. einem Lötpad auf. Für spezielle Anwendungen kann ein Steckkontaktteil jedoch auch mit zwei entsprechenden Steckanschlusselementen und/oder Lötanschlusselementen mit Toleranzausgleichstücken ausgebildet sein.In general, plug contact parts of an electrical connector each have only one plug connection element with a pin or a socket and a solder connection element with a solder pin or a solder pad. However, for special applications, a plug contact part may also be formed with two corresponding plug connection elements and / or solder connection elements with tolerance compensation pieces.
