Die vorliegende Erfindung ist ein Steckverbinder, insbesondere zum elektrischen Verbinden eines ersten Bauteils, insbesondere eines Flachbandkabels, mit einem zweiten Bauteil, insbesondere einer Leiterplatte, umfassend: einen isolierenden Gehäusekörper, welcher eine Kontaktaufnahme zum Aufnehmen eines Kontaktbereichs des ersten Bauteils entlang einer Aufnahmerichtung aufweist, und eine Vielzahl von identischen, nebeneinander angeordneten und durch den Gehäusekörper voneinander elektrisch isolierten und rückstellfähigen Kontaktbügeln, welche derart ausgebildet ist, den Kontaktbereich des ersten Bauteils in einem Kontaktzustand der Vielzahl von Kontaktbügeln elektrisch zu kontaktieren und das zweite Bauteil mit dem ersten Bauteil elektrisch zu verbinden, wobei die Vielzahl von Kontaktbügeln in einer ersten Anordnung relativ zu der Aufnahmerichtung und/oder in einer zweiten Anordnung relativ zu der Aufnahmerichtung angeordnet ist, und wobei die Kontaktaufnahme an dem Gehäusekörper derart positioniert ist, dass bei identischem Gehäusekörper in dem Kontaktzustand der Vielzahl von Kontaktbügeln jeder der Vielzahl von Kontaktbügeln in der ersten Anordnung eine erste vorbestimmbare Kontaktkraft auf den Kontaktbereich des ersten Bauteils ausübbbar ist, und jeder der Vielzahl von Kontaktbügeln in der zweiten Anordnung eine zweite vorbestimmbare Kontaktkraft auf den Kontaktbereich des ersten Bauteils ausübbar ist, wobei die erste Kontaktkraft von der zweiten Kontaktkraft verschieden ist.The present invention is a plug connector, in particular for electrically connecting a first component, in particular a ribbon cable, to a second component, in particular a printed circuit board, comprising: an insulating housing body which has a contact receptacle for receiving a contact area of the first component along a receiving direction, and a plurality of identical, arranged side by side and through the case body mutually electrically insulated and resilient contact clips, which are designed in such a way to electrically contact the contact region of the first component in a contact state of the plurality of contact clips and to electrically connect the second component to the first component, the plurality of contact clips being in a first arrangement relative to is arranged in the receiving direction and/or in a second arrangement relative to the receiving direction, and wherein the contact receptacle is positioned on the housing body in such a way that when the housing body is identical in the contact state of the plurality of contact clips, each of the plurality of contact clips in the first arrangement has a first predeterminable Contact force can be exerted on the contact area of the first component, and each of the plurality of contact clips in the second arrangement can exert a second predeterminable contact force on the contact area of the first component, the first contact force being different from the second contact force.

Wird der obige Steckverbinder verwendet, um ein erstes Bauteil elektrisch mit einem zweiten Bauteil mittels Steckverbindung zu verbinden, so wird der Kontaktbereich des ersten Bauteils entlang der Aufnahmerichtung in die in dem Gehäusekörper ausgebildete Kontaktaufnahme um eine durch die Gestalt der Kontaktaufnahme vorbestimmte Stecktiefe oder Eindringtiefe gesteckt bzw. geschoben, bis der Kontaktbereich des ersten Bauteils alle der Vielzahl von Kontaktbügeln berührt bzw. kontaktiert und sich in einer durch die Gestalt der Kontaktaufnahme und/oder durch die Gestalt der einzelnen Kontaktbügel vorbestimmten Steckposition befindet. Somit befindet sich die Vielzahl von Kontaktbügeln in einem Kontaktzustand.If the above connector is used to electrically connect a first component to a second component by means of a plug connection, the contact area of the first component is inserted or pushed along the receiving direction into the contact receptacle formed in the housing body by an insertion depth or penetration depth predetermined by the shape of the contact receptacle pushed until the contact area of the first component touches or contacts all of the plurality of contact clips and is in a plug-in position predetermined by the shape of the contact receptacle and/or by the shape of the individual contact clips. Thus, the plurality of contact straps are in a contact state.

Als Kontaktbereich ist derjenige Bereich zu verstehen, innerhalb dessen sich die elektrischen Kontakte des ersten Bauteils freiliegend erstrecken.The contact area is that area within which the electrical contacts of the first component extend in an exposed manner.

Die Aufnahmerichtung ist als diejenige Richtung zu verstehen, in die das erste Bauteil, insbesondere der Kontaktbereich des ersten Bauteils, in die Kontaktaufnahme des Gehäusekörpers hineingesteckt bzw. hineingeschoben wird, um den Kontaktbereich des ersten Bauteils in Kontakt mit allen der Vielzahl von Kontaktbügeln zu bringen (Kontaktzustand). Beispielsweise kann die Aufnahmerichtung parallel zu einer Erstreckungsrichtung der Kontaktaufnahme und/oder zu der Erstreckungsrichtung der Vielzahl von Kontaktbügeln sein oder verlaufen.The receiving direction is to be understood as the direction in which the first component, in particular the contact area of the first component, is inserted or pushed into the contact receptacle of the housing body in order to bring the contact area of the first component into contact with all of the plurality of contact clips ( contact state). For example, the receiving direction can be or run parallel to a direction of extent of the contact receptacle and/or to the direction of extent of the multiplicity of contact clips.

Die Kontaktaufnahme ist als Ausnehmung in dem Gehäusekörper zu verstehen.The contact is to be understood as a recess in the housing body.

Beim Einstecken bzw. Hineinschieben des Kontaktbereichs des ersten Bauteils in die Kontaktaufnahme des Gehäusekörpers drückt der Kontaktbereich des ersten Bauteils gegen einen Endbereich eines jeden Kontaktbügels der Vielzahl von Kontaktbügeln, welcher sich in die Kontaktaufnahme erstreckt, und drückt den Endbereich in eine Richtung quer zu der Aufnahmerichtung. In dem Kontaktzustand der Vielzahl von Kontaktbügeln wird der Endbereich in Abhängigkeit von der Position der Kontaktaufnahme relativ zu dem Gehäusekörper und von der Anordnung jedes Kontaktbügels der Vielzahl von Kontaktbügeln relativ zu dem Gehäusekörper und zu der Aufnahmerichtung bzw. Kontaktaufnahme um einen bestimmten, der Kontaktkraft, die benötigt wird, um eine elektrische Kontaktverbindung zwischen dem Kontaktbereich des ersten Bauteils und den Kontaktbügeln herzustellen, entsprechenden Weg in die Richtung quer zu der Aufnahmerichtung gedrückt bzw. ausgelenkt. Folglich meint der Begriff "vorbestimmbare Kontaktkraft" die Kraft, die der Kraft entspricht, um mittels Kontaktierens eine elektrische Kontaktverbindung zwischen dem Kontaktbereich des ersten Bauteils und der Endbereiche der Kontaktbügel in dem Kontaktzustand der Vielzahl von Kontaktbügeln herzustellen. Die auf den Kontaktbereich des ersten Bauteils oder den Endbereich der Kontaktbügel wirkende Kraft ist von der Auslenkung der Kontaktbügel, insbesondere der Endbereiche der Kontaktbügel, beim Einschieben bzw. Einstecken des Kontaktbereichs des ersten Bauteils in die Kontaktaufnahme in Aufnahmerichtung abhängig.When the contact area of the first component is inserted or pushed into the contact receptacle of the housing body, the contact area of the first component presses against an end area of each contact clip of the plurality of contact clips, which extends into the contact receptacle, and presses the end area in a direction transverse to the receiving direction . In the contact state of the plurality of contact clips, the end region is moved by a certain amount, the contact force, depending on the position of the contact socket relative to the housing body and the arrangement of each contact clip of the plurality of contact clips relative to the housing body and the receiving direction or contact socket is required to produce an electrical contact connection between the contact area of the first component and the contact clips, corresponding path in the direction transverse to the recording direction is pressed or deflected. Consequently, the term "predeterminable contact force" means the force that corresponds to the force to establish an electrical contact connection between the contact area of the first component and the end areas of the contact straps in the contact state of the plurality of contact straps by means of contacting. The force acting on the contact area of the first component or the end area of the contact clip depends on the deflection of the contact clip, in particular the end area of the contact clip, when the contact area of the first component is pushed in or plugged into the contact receptacle in the receiving direction.

Die Kontaktkraft kann bestimmt werden, wenn das Kontaktmaterial bzw. der Kontakttyp des Kontaktbereichs des ersten Bauteils und das Material, aus dem die Vielzahl von Kontaktbügeln geformt ist oder mit dem jeder Kontaktbügel der Vielzahl von Kontaktbügeln beschichtet ist, bekannt sind.The contact force can be determined if the contact material or the contact type of the contact area of the first component and the material from which the plurality of contact straps is formed or with which each contact strap of the plurality of contact straps is known are known.

Vorteilhafterweise verringert der bisher beschriebene Steckverbinder den Verschleiß, insbesondere den Abrieb, der elektrischen Kontakte sowohl des ersten Bauteils als auch des Steckverbinders, wobei der Steckverbinder eine ideale elektrische Kontaktverbindung zwischen dem ersten Bauteil und dem zweiten Bauteil bewirkt.Advantageously, the plug connector described so far reduces wear, in particular abrasion, of the electrical contacts of both the first component and the plug connector, with the plug connector bringing about an ideal electrical contact connection between the first component and the second component.

Je nach Anordnung der Kontaktbügel werden die Endbereiche der Kontaktbügel um verschiedene Wege aus ihrer Ausgangslage, bevor das erste Bauteil in die Kontaktaufnahme hineingesteckt bzw. hineingeschoben worden ist, ausgelenkt, wenn der Kontaktbereich des ersten Bauteils in die Kontaktaufnahme hineingesteckt bzw. hineingeschoben wird. Nach Entfernen bzw. Herausziehen des Kontaktbereichs des ersten Bauteils aus der Kontaktaufnahme kehren die Kontaktbügel in ihre Ausgangslage zurück. Demnach verfügt jeder Kontaktbügel der Vielzahl von Kontaktbügeln über Federeigenschaften. Je nach Anordnung der Kontaktbügel weisen die Kontaktbügel unterschiedliche Federwege auf.Depending on the arrangement of the contact brackets, the end areas of the contact brackets are different ways from their initial position before the first component has been inserted or pushed into the contact receptacle when the contact area of the first component is inserted or pushed into the contact receptacle. After the contact area of the first component has been removed or pulled out of the contact receptacle, the contact brackets return to their initial position. Accordingly, each contact strap of the plurality of contact straps has spring properties. Depending on the arrangement of the contact brackets, the contact brackets have different spring deflections.

Die Vielzahl von Kontaktbügeln ist entweder ausschließlich in der ersten Anordnung oder ausschließlich in der zweiten Anordnung angeordnet oder die Vielzahl von Kontaktbügeln ist zu einem Teil in der ersten Anordnung und zu einem anderen Teil in der zweiten Anordnung angeordnet. Eine Teilmenge der Vielzahl von Kontaktbügeln kann in der ersten Anordnung angeordnet sein, wobei der Rest der Vielzahl von Kontaktbügeln in der zweiten Anordnung angeordnet sein kann.The plurality of contact straps are arranged either exclusively in the first arrangement or exclusively in the second arrangement, or the plurality of contact straps are arranged partly in the first arrangement and partly in the second arrangement. A subset of the plurality of contact straps may be arranged in the first array, and the remainder of the plurality of contact straps may be arranged in the second array.

Um ihren Endbereich herum sind die Kontaktbügel, insbesondere alle Kontaktbügel, quer zu der Aufnahmerichtung gekrümmt bzw. entlang der Aufnahmerichtung bügelförmig ausgebildet. Die Geometrie der Kontaktbügel in ihren Endbereichen trägt dazu bei, dass die erste Kontaktkraft und die zweite Kontaktkraft beeinflusst, insbesondere eingestellt, werden können.Around their end area, the contact clips, in particular all contact clips, are curved transversely to the receiving direction or are designed in the shape of a clip along the receiving direction. The geometry of the contact brackets in their end regions contributes to the fact that the first contact force and the second contact force can be influenced, in particular adjusted.

Diejenigen Kontaktbügel der Vielzahl von Kontaktbügeln, die sich in der ersten Anordnung befinden, üben im Kontaktzustand der Vielzahl von Kontaktbügeln die erste Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus, und diejenigen Kontaktbügel der Vielzahl von Kontaktbügeln, die sich in der zweiten Anordnung befinden, üben im Kontaktzustand der Vielzahl von Kontaktbügeln die zweite Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus. Befinden sich die Kontaktbügel nur in der ersten Anordnung, üben sie im Kontaktzustand nur die erste Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus. Befinden sich die Kontaktbügel dagegen nur in der zweiten Anordnung, üben sie im Kontaktzustand nur die zweite Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus. Ist ein Teil der Kontaktbügel in der ersten Anordnung angeordnet und ist der Rest der Kontaktbügel in der zweiten Anordnung angeordnet, so üben die Kontaktbügel in der ersten Anordnung im Kontaktzustand die erste Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus und die Kontaktbügel in der zweiten Anordnung üben im Kontaktzustand die zweite Kontaktkraft auf den Kontaktbereich des ersten Bauteils aus.Those contact clips of the plurality of contact clips that are in the first arrangement exert the first contact force on the contact area of the first component in the contact state of the plurality of contact clips, and those contact clips of the plurality of contact clips that are in the second arrangement exercise in the contact state of the plurality of contact clips, the second contact force exerts itself on the contact area of the first component. If the contact clips are only in the first arrangement, they only exert the first contact force on the contact area of the first component in the contact state. If, on the other hand, the contact clips are only in the second arrangement, they only exert the second contact force on the contact area of the first component in the contact state. If part of the contact straps are arranged in the first arrangement and the rest of the contact straps are arranged in the second arrangement, the contact straps in the first arrangement practice the first arrangement in the contact state Contact force on the contact area of the first component and the contact straps in the second arrangement exert the second contact force on the contact area of the first component in the contact state.

Vorteilhafterweise lässt sich gemäß des oben Beschriebenen ein Steckverbinder realisieren, der auf einfache und kostengünstige Weise für mehrere Kontaktmaterialien bzw. Kontakttypen des Kontaktbereichs des ersten Bauteils verwendet werden kann. Der oben beschriebene Steckverbinder kann für verschiedene Anwendungen nach einem einfachen Baukastenprinzip hergestellt werden.Advantageously, according to what is described above, a connector can be implemented that can be used in a simple and cost-effective manner for a plurality of contact materials or contact types of the contact area of the first component. The connector described above can be manufactured for various applications using a simple modular principle.

Vorzugsweise entspricht die erste vorbestimmbare Kontaktkraft der Kontaktkraft von goldbeschichteten Kontakten und die zweite vorbestimmbare Kontaktkraft entspricht der Kontaktkraft von zinnbeschichteten Kontakten. Alternativ entspricht die erste vorbestimmbare Kontaktkraft der Kontaktkraft von zinnbeschichteten Kontakten und die zweite vorbestimmbare Kontaktkraft entspricht der Kontaktkraft von goldbeschichteten Kontakten.Preferably, the first predeterminable contact force corresponds to the contact force of gold-plated contacts and the second predeterminable contact force corresponds to the contact force of tin-plated contacts. Alternatively, the first predeterminable contact force corresponds to the contact force of tin-plated contacts and the second predeterminable contact force corresponds to the contact force of gold-plated contacts.

Vorteilhafterweise kann so der Verschleiß, insbesondere der Abrieb, der elektrischen Kontakte unterschiedlicher Materialgruppen verringert werden und ein verlässlicher elektrischer Kontakt sichergestellt werden.In this way, wear and tear, in particular abrasion, of the electrical contacts of different material groups can advantageously be reduced and reliable electrical contact can be ensured.

Weiterhin vorteilhafterweise lässt sich somit der beschrieben Steckverbinder auf einfache und kostengünstige Weise für verschiedene Kontaktmaterialgruppen wie z. B. Edelmetalle, aber auch andere Schwermetalle, verwenden. Der Steckverbinder kann zum Beispiel für zwei Kontaktmaterialien bzw. Kontakttypen des Kontaktbereichs des ersten Bauteils, nämlich für Gold- und/oder Zinnkontakte oder vergoldete und/oder verzinnte Kontakte, ausgelegt sein.Furthermore, advantageously, the connector described can thus be used in a simple and cost-effective manner for different contact material groups, such as e.g. As precious metals, but also other heavy metals use. The connector can be designed, for example, for two contact materials or contact types of the contact area of the first component, namely for gold and/or tin contacts or gold-plated and/or tin-plated contacts.

Vorzugsweise wird die Vielzahl von Kontaktbügeln, insbesondere jeder der Vielzahl von Kontaktbügeln, je nach Eindringtiefe des Kontaktbereichs des ersten Bauteils in die Kontaktaufnahme entweder teilweise oder vollständig aus der Kontaktaufnahme verdrängt wird. Genauer gesagt werden die Endbereiche der Kontaktbügel aus der Kontaktaufnahme entweder teilweise oder vollständig quer zu der Aufnahmerichtung aus der Kontaktaufnahme verdrängt bzw. gedrückt.Preferably, the multiplicity of contact clips, in particular each of the multiplicity of contact clips, is displaced either partially or completely from the contact receptacle, depending on the penetration depth of the contact region of the first component into the contact receptacle. To put it more precisely, the end regions of the contact clips are either partially or completely displaced or pressed out of the contact receptacle transversely to the receiving direction.

Vorzugsweise wird beim Aufnehmen des Kontaktbereichs des ersten Bauteils in der Kontaktaufnahme jeder der Vielzahl von Kontaktbügeln in der ersten Anordnung um einen von der ersten Anordnung abhängigen ersten Betrag ausgelenkt, Weiter vorzugsweise wird beim Aufnehmen des Kontaktbereichs des ersten Bauteils in der Kontaktaufnahme jeder der Vielzahl von Kontaktbügeln in der zweiten Anordnung um einen von der zweiten Anordnung abhängigen zweiten Betrag ausgelenkt. Hierbei sind der erste Betrag und der zweite Betrag voneinander verschieden.Preferably, when receiving the contact area of the first component in the contact receptacle, each of the plurality of contact clips in the first arrangement is deflected by a first amount dependent on the first arrangement. More preferably, when receiving the contact area of the first component in the contact receptacle, each of the plurality of contact clips in the second arrangement is deflected by a second amount dependent on the second arrangement. In this case, the first amount and the second amount are different from one another.

Der erste Betrag kann in einer mathematischen Beziehung zu der ersten Kontaktkraft stehen und der zweite Betrag kann in einer mathematischen Beziehung zu der zweiten Kontaktkraft stehen. Zum Beispiel kann die erste Kontaktkraft direkt proportional zu dem ersten Betrag sein und die zweite Kontaktkraft kann direkt proportional zu dem zweiten Betrag sein. Die erste Kontaktkraft kann aber auch quadratisch, kubisch oder polynomial von dem ersten Betrag abhängen. Die zweite Kontaktkraft kann ebenfalls quadratisch, kubisch oder polynomial von dem zweiten Betrag abhängen.The first magnitude can be mathematically related to the first contact force and the second magnitude can be mathematically related to the second contact force. For example, the first contact force can be directly proportional to the first magnitude and the second contact force can be directly proportional to the second magnitude. However, the first contact force can also depend quadratically, cubically or polynomially on the first amount. The second contact force can also depend quadratically, cubically or polynomially on the second amount.

Vorzugsweise erstreckt sich jeder der Vielzahl von Kontaktbügeln in der ersten Anordnung ohne den in der Kontaktaufnahme aufgenommenen Kontaktbereich des ersten Bauteils weiter in die Kontaktaufnahme als in der zweiten Anordnung. Alternativ erstreckt sich jeder der Vielzahl von Kontaktbügeln in der zweiten Anordnung ohne den in der Kontaktaufnahme aufgenommenen Kontaktbereich des ersten Bauteils weiter in die Kontaktaufnahme als in der ersten Anordnung.Preferably, each of the plurality of contact straps in the first arrangement extends further into the contact receptacle than in the second arrangement without the contact portion of the first component being received in the contact receptacle. Alternatively, each of the plurality of contact straps in the second arrangement, without the contact portion of the first component received in the contact receptacle, extends further into the contact receptacle than in the first arrangement.

Jeder der Kontaktbügel kann derart geformt sein, dass er in dem Zustand, in dem kein elektrischer Kontakt zwischen dem ersten Bauteil und den Kontaktbügeln besteht, d. h. wenn sich der Kontaktbereich des ersten Bauteils nicht oder nicht vollständig in der Kontaktaufnahme des Gehäusekörpers befindet, teilweise, insbesondere an seinem Endbereich, in die Kontaktaufnahme hineinragt.Each of the contact straps may be shaped such that in the condition in which there is no electrical contact between the first component and the contact straps, ie. H. if the contact area of the first component is not located or is not completely located in the contact receptacle of the housing body, partially, in particular at its end region, protrudes into the contact receptacle.

Jeder der Vielzahl von Kontaktbügeln kann weiterhin derart ausgebildet sein, dass er entgegen der Aufnahmerichtung eine Krümmung bzw. einen Knick aufweist. Die Krümmung bzw. der Knick kann in der ersten Anordnung konkav sein und in der zweiten Anordnung konvex. Alternativ kann die Krümmung bzw. der Knick in der ersten Anordnung konvex sein und in der zweiten Anordnung konkav. Die Krümmung bzw. der Knick besitzt einen Extrempunkt.Each of the multiplicity of contact clips can also be designed in such a way that it has a curvature or a kink counter to the receiving direction. The bend or kink may be concave in the first configuration and convex in the second configuration. Alternatively, the curvature or the kink in the first arrangement may be convex and in the second arrangement concave. The curvature or kink has an extreme point.

Die Krümmung bzw. der Knick kann bügelförmig sein und der Extrempunkt kann ein Bügelmaximum oder ein Bügelminimum sein.The curvature or kink can be bow-shaped and the extreme point can be a bow maximum or a bow minimum.

Jeder der Vielzahl von Kontaktbügeln und der Gehäusekörper können derart ausgebildet sein, dass der Extrempunkt der Krümmung bzw. des Knicks eines jeden Kontaktbügels in der ersten Anordnung einen ersten vorbestimmbaren und/oder vorbestimmten Abstand von einer ersten Innenfläche der Kontaktaufnahme hat und der Extrempunkt der Krümmung bzw. des Knicks eines jeden Kontaktbügels in der zweiten Anordnung einen zweiten vorbestimmbaren und/oder vorbestimmbaren Abstand von einer zweiten der ersten Innenfläche gegenüberliegenden Innenfläche der Kontaktaufnahme hat.Each of the plurality of contact clips and the housing body can be designed in such a way that the extreme point of the curvature or the kink of each contact clip in the first arrangement has a first predeterminable and/or predetermined distance from a first inner surface of the contact receptacle and the extreme point of the curvature or the kink of each contact clip in the second arrangement has a second predefinable and/or predefinable distance from a second inner surface of the contact receptacle opposite the first inner surface.

Der erste Abstand kann größer als der zweite Abstand sein. Alternativ kann der zweite Abstand größer als der erste Abstand sein.The first distance can be greater than the second distance. Alternatively, the second distance can be greater than the first distance.

Beispielsweise können die Kontaktbügel in Abhängigkeit vom Kontaktmaterial in der ersten Anordnung um 0,1 mm in die Kontaktaufnahme hineinragen, d. h. der erste Abstand kann 0,1 mm betragen, wobei die Kontaktbügel in der zweiten Anordnung um 0,2 mm in die Kontaktaufnahme hineinragen können, d. h. der zweite Abstand kann 0,2 mm betragen.For example, depending on the contact material in the first arrangement, the contact straps can protrude by 0.1 mm into the contact receptacle, i. H. the first distance can be 0.1 mm, the contact straps in the second arrangement being able to protrude into the contact receptacle by 0.2 mm, ie. H. the second distance can be 0.2 mm.

Vorzugsweise ist die Vielzahl von Kontaktbügeln derart ausgebildet, dass der Gehäusekörper stehend oder liegend mit dem zweiten Bauteil verlötet werden kann.The multiplicity of contact clips is preferably designed in such a way that the housing body can be soldered to the second component in an upright or horizontal position.

Vorteilhafterweise kann hierdurch der Steckverbinder in Bereichen eingesetzt werden, die einen geringen Raumbedarf haben oder erfordern. Da der Steckverbinder sich auf unterschiedliche Weise mit dem zweiten Bauteil verbinden lässt, kann der Steckverbinder flexibel verbaut werden.Advantageously, this allows the connector to be used in areas that have or require little space. Since the connector can be connected to the second component in different ways, the connector can be installed flexibly.

Der Gehäusekörper kann aus einem elektrisch isolierenden Material wie zum Beispiel Plastik geformt sein. Der Gehäusekörper kann einteilig oder mehrteilig ausgebildet sein und er kann ganz oder teilweise im Spritzgussverfahren oder mittels eines 3D-Druckers hergestellt werden.The housing body may be molded from an electrically insulating material such as plastic. The housing body can be designed in one piece or in multiple pieces and it can be manufactured in whole or in part by injection molding or by means of a 3D printer.

Vorzugsweise ist die Vielzahl von Kontaktbügeln gestanzt. Insbesondere ist jeder Kontaktbügel der Vielzahl von Kontaktbügeln gestanzt bzw. ein Stanzteil.Preferably, the plurality of contact straps is stamped. In particular, each contact clip of the plurality of contact clips is stamped or a stamped part.

Vorzugsweise ist die Vielzahl von Kontaktbügeln galvanisiert, wobei die Vielzahl von Kontaktbügeln insbesondere mittels eines Goldbads oder mittels eines Zinnbads galvanisiert ist. Insbesondere ist jeder Kontaktbügel der Vielzahl von Kontaktbügeln galvanisiert, wobei jeder Kontaktbügel der Vielzahl von Kontaktbügeln insbesondere mittels eines Goldbads oder mittels eines Zinnbads galvanisiert ist.The multiplicity of contact clips is preferably electroplated, with the multiplicity of contact clips being electroplated in particular by means of a gold bath or by means of a tin bath. In particular, each contact clip of the multiplicity of contact clips is electroplated, with each contact clip of the multiplicity of contact clips being electroplated in particular by means of a gold bath or by means of a tin bath.

Vorzugsweise ist der Gehäusekörper relativ zu der Kontaktaufnahme asymmetrisch ausgebildet.The housing body is preferably designed asymmetrically relative to the contact receptacle.

Vorteilhafterweise können so die erste Kontaktkraft in der ersten Anordnung und die zweite Kontaktkraft in der zweiten Anordnung weiter beeinflusst, insbesondere eingestellt, werden.In this way, the first contact force in the first arrangement and the second contact force in the second arrangement can advantageously be further influenced, in particular adjusted.

Vorzugsweise sind die erste Anordnung und die zweite Anordnung nicht spiegelsymmetrisch relativ zu der Kontaktaufnahme.Preferably, the first array and the second array are not mirror symmetrical relative to the contact receptacle.

Vorteilhafterweise wird hierdurch dazu beigetragen, dass die erste Kontaktkraft in der ersten Anordnung von der zweiten Kontaktkraft in der zweiten Anordnung verschieden ist.This advantageously contributes to the fact that the first contact force in the first arrangement differs from the second contact force in the second arrangement.

Vorzugsweise sind die erste Anordnung und die zweite Anordnung zueinander verdrehte Anordnungen, wobei insbesondere die zweite Anordnung eine um 180° gegen die erste Anordnung relativ zu der Aufnahmerichtung verdrehte Anordnung ist. Insbesondere kann die zweite Anordnung eine um 180° gegen die erste Anordnung um eine Achse entlang der Aufnahmerichtung verdrehte Anordnung sein.Preferably, the first arrangement and the second arrangement are arrangements rotated relative to one another, with the second arrangement in particular being an arrangement rotated by 180° with respect to the first arrangement relative to the recording direction. In particular, the second arrangement can be an arrangement rotated by 180° with respect to the first arrangement about an axis along the recording direction.

Vorteilhafterweise wird hierdurch weiter dazu beigetragen, dass die erste Kontaktkraft in der ersten Anordnung von der zweiten Kontaktkraft in der zweiten Anordnung verschieden ist. Außerdem lässt sich der Aufwand der Lagerhaltung reduzieren und es lassen sich mit identischen Bauteilen verschiedene Steck- bzw. Steckerkonfigurationen ermöglichen.Advantageously, this further contributes to the fact that the first contact force in the first arrangement differs from the second contact force in the second arrangement is different. In addition, the storage effort can be reduced and different plug and connector configurations can be made possible with identical components.

Vorzugsweise entspricht die erste vorbestimmbare Kontaktkraft einer Kraft, um den aus einem ersten Material geformten oder mit einem ersten Material beschichteten Kontaktbereich des ersten Bauteils in elektrischen Kontakt mit einem der Vielzahl von Kontaktbügeln zu bringen, und die zweite vorbestimmbare Kontaktkraft entspricht einer Kraft, um den aus einem zweiten Material geformten oder mit einem zweiten Material beschichteten Kontaktbereich des ersten Bauteils in elektrischen Kontakt mit einem der Vielzahl von Kontaktbügeln zu bringen. Insbesondere kann das erste Material Gold und das zweite Material Zinn sein. Alternativ kann das erste Material aber auch Zinn und das zweite Material Gold sein.Preferably, the first predeterminable contact force corresponds to a force to bring the contact region of the first component formed from a first material or coated with a first material into electrical contact with one of the plurality of contact clips, and the second predeterminable contact force corresponds to a force to a second material molded or coated with a second material contact portion of the first component in electrical contact with one of the plurality of contact straps. In particular, the first material can be gold and the second material can be tin. Alternatively, the first material can also be tin and the second material can be gold.

Vorzugsweise ist das erste Bauteil ein Flachbandkabel und das zweite Bauteil eine Leiterplatte.The first component is preferably a ribbon cable and the second component is a printed circuit board.

Der vordere Teil 12a und der hintere Teil 12b des Gehäusekörpers 12 können beispielsweise zusammengesteckt oder-geschraubt werden und so den Gehäusekörper 12 bilden.The front part 12a and the rear part 12b of the housing body 12 can, for example, be plugged or screwed together and thus form the housing body 12.

Die Kontaktbügel 16 erstrecken sich aus dem Inneren des vorderen Teils 12a des Gehäusekörpers 12 in Richtung der Aufnahmerichtung AR und ragen im Wesentlichen aus einem zentralen Bereich des vorderen Teils 12a des Gehäusekörpers 12 hervor, sodass die hervorragenden Enden der Kontaktbügel 16 mit einem zweiten Bauteil 20 wie einer Leiterplatte bzw. einer Platine (hier nicht gezeigt, siehe unten Figur 4 und 5) elektrisch verbunden werden können oder in elektrischen Kontakt mit dem zweiten Bauteil 20 wie einer Leiterplatte bzw. einer Platine gebracht werden können. Die Kontaktbügel 16 sind in y-Richtung, d. h. senkrecht zu der Aufnahmerichtung, alle parallel zueinander in der Anordnung A1 (siehe auch Figuren 3, 4, 5 und 6) angeordnet und durch die Form des vorderen Teils 12a des Gehäusekörpers 12 elektrisch isoliert und getrennt voneinander angeordnet (siehe auch Figur 2).The contact straps 16 extend from the interior of the front part 12a of the housing body 12 in the direction of the receiving direction AR and protrude substantially from a central region of the front part 12a of the housing body 12, so that the protruding ends of the contact straps 16 are connected to a second component 20 such as a circuit board or circuit board (not shown here, see below figure 4 and 5 ) can be electrically connected or can be brought into electrical contact with the second component 20 such as a printed circuit board or a circuit board. The contact brackets 16 are in the y-direction, ie perpendicular to the recording direction, all parallel to one another in the arrangement A1 (see also figures 3 , 4 , 5 and 6 ) and arranged electrically insulated and separated from each other by the shape of the front part 12a of the case body 12 (see also figure 2 ).

Figur 2 zeigt eine perspektivische Vorderansicht der in Figur 1 gezeigten Ausführungsform des Steckverbinders 10. Im Vergleich zu Figur 1 ist die in Figur 2 gezeigte Ansicht um 90° um die z-Achse gedreht. figure 2 shows a perspective front view of FIG figure 1 shown embodiment of the connector 10. Compared to figure 1 is the in figure 2 shown rotated by 90° around the z-axis.

Figur 3 zeigt einen Querschnitt des in den Figuren 1 und 2 gezeigten Steckverbinders 10 entlang der Aufnahmerichtung AR durch einen Kontaktbügel 16. Der gezeigte Querschnitt des Steckverbinders 10 zeigt, dass sich der Kontaktbügel 16 (das Gleiche gilt für alle anderen nicht gezeigten Kontaktbügel 16) in der Anordnung A1 angeordnet ist. Die Kontaktbügel 16 erstrecken sich entgegen der Aufnahmerichtung AR in den vorderen Teil 12a des Gehäusekörpers 12 hinein und weisen in ihrem Endbereich entgegen der Aufnahmerichtung AR in der xz-Ebene eine Krümmung bzw. einen Knick 26 auf. Durch die Krümmung bzw. den Knick 26 sind die Kontaktbügel 16 zu einem Bügel gekrümmt ausgebildet. In der Anordnung A1 ragt ein Bereich um die Extrempunkte der Bügel 28 (Bügelmaxima) der bügelförmigen Endbereiche 26 der Kontaktbügel 16 herum in z-Richtung in die Kontaktaufnahme 14 hinein, sodass die Bügelmaxima 28 um einen von der Gestalt des Gehäusekörpers 12 und der Kontaktaufnahme 14 abhängigen Abstand d zwischen Bügelmaximum 26 und der auf die z-Achse bezogenen, unteren Innenfläche 22 der Kontaktaufnahme 14 in der Kontaktaufnahme 14 haben. In der zweiten Anordnung A2 würde der Kontaktbügel 16 um einen von dem Abstand d verschiedenen Abstand zwischen dem Extrempunkt 28 der Krümmung bzw. des Knicks 26 und der oberen Innenfläche 24 der Kontaktaufnahme 14 in die Kontaktaufnahme 14 hineinragen. figure 3 shows a cross section of in the figures 1 and 2 shown connector 10 along the receiving direction AR by a contact clip 16. The cross section of the connector 10 shown shows that the contact clip 16 (the same applies to all other contact clips 16 not shown) is arranged in the arrangement A1. The contact clips 16 extend counter to the receiving direction AR into the front part 12a of the housing body 12 and have a curvature or a kink 26 in their end region counter to the receiving direction AR in the xz plane. Due to the curvature or the kink 26, the contact brackets 16 are curved to form a bracket. In arrangement A1, an area around the extreme points of the brackets 28 (clip maxima) of the bracket-shaped end regions 26 of the contact brackets 16 protrudes in the z-direction into the contact receptacle 14, so that the bracket maxima 28 differ from the shape of the housing body 12 and the contact receptacle 14 dependent distance d between bracket maximum 26 and related to the z-axis, lower inner surface 22 of contact receptacle 14 in contact receptacle 14. In the second arrangement A2, the contact bracket 16 would protrude into the contact receptacle 14 by a distance different from the distance d between the extreme point 28 of the curvature or the kink 26 and the upper inner surface 24 of the contact receptacle 14.

Beim Einschieben bzw. Einstecken des Kontaktbereichs KB eines ersten Bauteils 18 (angedeutet durch das gestrichelte Rechteck in der Kontaktaufnahme 14), wie z. B. eines Flachbandkabels, wird der Bereich um die Bügelmaxima herum um einen von der Krümmung und dem Material der Kontaktbügel 16 und dem Material des Kontaktbereichs KB abhängigen Weg in z-Richtung nach unten gedrückt bzw. ausgelenkt. Der Abstand d verringert sich dadurch.When inserting or plugging in the contact area KB of a first component 18 (indicated by the dashed rectangle in the contact 14), such as. B. a ribbon cable, the area around the clip maxima around a dependent on the curvature and the material of the contact clip 16 and the material of the contact area KB path in the z-direction is pressed or deflected downwards. This reduces the distance d.

Daraus resultiert eine Gegenkraft F1 der Kontaktbügel 16 auf den Kontaktbereich KB. Figur 3 zeigt die z-Komponente der Gegenkraft F1. Die Gegenkraft F1 entspricht hierbei der Kontaktkraft F1, die benötigt wird, um die Kontaktbügel 16 und den Kontaktbereich KB in elektrischen Kontakt zu bringen, also um eine elektrische Kontaktverbindung herzustellen. Hierbei ist der Kontaktbereich KB aus einem bestimmten Material, wie z. B. Gold, geformt oder mit diesem beschichtet. Die Kontaktkraft F1 ist folglich die für Gold wesentliche Kontaktkraft.This results in a counterforce F1 of the contact clip 16 on the contact area KB. figure 3 shows the z-component of the counterforce F1. In this case, the counterforce F1 corresponds to the contact force F1, which is required in order to bring the contact clip 16 and the contact area KB into electrical contact, that is to say in order to produce an electrical contact connection. Here, the contact area KB is made of a specific material, such as. B. gold, formed or coated with this. The contact force F1 is consequently the contact force that is essential for gold.

Die Figuren 4 und 5 zeigen den Querschnitt des Steckverbinders 10 wie in Figur 3 gezeigt einmal stehend und einmal liegend mit einem zweiten Bauteil 20, wie z. B. einer Leiterplatte (angedeutet durch das gestrichelte Rechteck 20), verlötet. Figur 4 zeigt, dass die Leiterplatte 20 stehend mit dem Gehäusekörper 12 verlötet werden kann, wohingegen Figur 5 zeigt, dass die Leiterplatter 20 auch liegend mit dem Gehäusekörper 12 verlötet werden kann.The figures 4 and 5 show the cross section of the connector 10 as in figure 3 shown once standing and once lying down with a second component 20, such as. B. a printed circuit board (indicated by the dashed rectangle 20), soldered. figure 4 shows that the circuit board 20 can be soldered standing to the housing body 12, whereas FIG figure 5 shows that the printed circuit board 20 can also be soldered to the housing body 12 lying flat.

Figur 6 zeigt die erste Anordnung A1 und die zweite Anordnung A2 der Kontaktbügel 16 im Vergleich. Die Anordnung A1 entspricht der in Figur 3 gezeigten Anordnung A1 der Kontaktbügel 16, wobei bei eingeschobenem bzw. eingestecktem Kontaktbereich KB in Aufnahmerichtung AR der gezeigte Kontaktbügel 16 in der ersten Anordnung A1 weggedrückt bzw. ausgelenkt wird und so die Kontaktkraft F1 auf den Kontaktbereich KB wirkt. figure 6 shows the first arrangement A1 and the second arrangement A2 of the contact clip 16 in comparison. The arrangement A1 corresponds to that in figure 3 shown arrangement A1 of the contact clip 16, with the contact area KB being pushed or inserted in the receiving direction AR of the contact clip 16 shown being pushed away or deflected in the first arrangement A1 and the contact force F1 thus acting on the contact area KB.

Die zweite Anordnung A2 ist um 180° zu der ersten Anordnung A1 um eine Achse entlang der Aufnahmerichtung AR gedreht. Die zweite Anordnung A2 ist vertikal gespiegelt zu der ersten Anordnung A1. Bei unveränderter Geometrie und Form des Gehäusekörpers 12 bzw. gleichbleibender Position bzw. Lage der Kontaktaufnahme 14 an dem Gehäusekörper 12 (angedeutet durch die gepunktete Linie, die durch die Anordnung A1 und die Anordnung A2 verläuft) und damit gleichbleibender Aufnahmerichtung AR muss nun der Bereich um das Bügelminimum herum des gezeigten Kontaktbügels 16 um einen im Vergleich zu der ersten Anordnung A1 größeren Weg in z-Richtung nach oben gedrückt bzw. ausgelenkt werden. Das resultiert in einer entsprechenden Gegenkraft F2 des Kontaktbügels 16 auf den Kontaktbereich KB, die von der Kraft F1 verschieden ist.The second arrangement A2 is rotated 180° to the first arrangement A1 about an axis along the recording direction AR. The second array A2 is mirrored vertically to the first array A1. With unchanged geometry and shape of the housing body 12 or the same position or location of the contact receptacle 14 on the housing body 12 (indicated by the dotted line that runs through the arrangement A1 and the arrangement A2) and thus the same receiving direction AR, the area around the clip minimum around the shown contact clip 16 can be pushed or deflected upwards by a distance that is greater in the z-direction than in the first arrangement A1. This results in a corresponding counterforce F2 of the contact clip 16 on the contact area KB, which is different from the force F1.

Durch die Form bzw. Ausgestaltung des Gehäusekörpers 12 und die Position bzw. Lage der Kontaktaufnahme 14 an dem Gehäusekörper 12 können die ebenfalls von der Anordnung der Kontaktbügel 16 in der ersten Anordnung A1 oder der zweiten Anordnung A2 abhängigen Kräfte F1 und F2 derart eingestellt werden, dass sie den Kontaktkräften F1 und F2 für unterschiedliche Kontakttypen bzw. -materialien entsprechen. So kann die Kraft F1 zum Beispiel der Kontaktkraft F1 für Gold und die Kraft F2 der Kontaktkraft F2 für Zinn entsprechen oder die Kraft F1 kann der Kontaktkraft F1 für Zinn und die Kraft F2 der Kontaktkraft F2 für Gold entsprechen.Due to the shape or configuration of the housing body 12 and the position or position of the contact receptacle 14 on the housing body 12, the forces F1 and F2, which are also dependent on the arrangement of the contact clips 16 in the first arrangement A1 or the second arrangement A2, can be set in such a way that that they correspond to the contact forces F1 and F2 for different contact types and materials. For example, the force F1 can correspond to the contact force F1 for gold and the force F2 to the contact force F2 for tin, or the force F1 can correspond to the contact force F1 for tin and the force F2 correspond to the contact force F2 for gold.

Auf diese Weise kann der Steckverbinder 10 einfach und mit geringem Aufwand, was Produktionskosten und Lagerung betrifft, für das elektrische Verbinden von zwei unterschiedlichen Typen von zum Beispiel Flachbandkabeln, die entweder aus Gold geformte bzw. vergoldete oder aus Zinn geformte bzw. verzinnte Kontaktbereiche aufweisen, mit einer Leiterplatte bzw. Platine bereitgestellt werden. D. h. mittels des Steckverbinders 10 lassen sich mit identischen Bauteilen, wie Gehäusekörper 12 und Kontaktbügel 16, verschiedene Steck- bzw. Steckerkonfigurationen für verschiedene Anwendungen bewerkstelligen. Außerdem wird durch den Steckverbinder 10 der Verschleiß, insbesondere den Abrieb, der elektrischen Kontakte sowohl des ersten Bauteils 18 als auch des Steckverbinders 10, wobei der Steckverbinder 10 eine ideale elektrische Kontaktverbindung zwischen dem ersten Bauteil 18 und dem zweiten Bauteil 20 bewirkt, verringert und eine verlässliche elektrische Verbindung bzw. ein elektrischer Kontakt gewährleistet. Zudem kann der Steckverbinder 10 in Bereichen eingesetzt werden, die einen geringen Raumbedarf haben oder erfordern. Da der Steckverbinder 10 sich auf unterschiedliche Weise mit dem zweiten Bauteil 20 verbinden lässt, kann der Steckverbinder 10 flexibel verbaut werden.In this way, the plug connector 10 can be used easily and with little effort in terms of production costs and storage for the electrical connection of two different types of, for example, flat ribbon cables, which have either gold-shaped or gold-plated or tin-shaped or tinned contact areas. be provided with a printed circuit board or circuit board. i.e. By means of the plug connector 10, different plug or connector configurations for different applications can be achieved with identical components, such as the housing body 12 and the contact clip 16. In addition, the connector 10 reduces the wear, in particular the abrasion, of the electrical contacts of both the first component 18 and the connector 10, the connector 10 causing an ideal electrical contact connection between the first component 18 and the second component 20 and a reliable electrical connection or electrical contact is guaranteed. In addition, the connector 10 can be used in areas that have or require little space. Since the connector 10 can be connected to the second component 20 in different ways, the connector 10 can be installed flexibly.
