Description
Die Erfindung betrifft eine Steckverbindung.The invention relates to a connector.
Eine elektrische Steckverbindung umfasst oft zwei Komponenten, insbesondere eine Feder-und eine Stiftleiste. Die Stiftleiste wird auch als Messerleiste bezeichnet.An electrical connector often comprises two components, in particular a spring and a pin header. The pin header is also referred to as a male connector.
Diese Komponenten sind starre Bauelemente, die jeweils insbesondere mit einem Gehäuseteil verbunden sind oder selbst gehäusebildende Funktion aufweisen. Daher müssen die Komponenten beim Stecken und Trennen, also beim Verbinden und Lösen, relativ genau aufeinander zu bewegt werden. Die Abweichung von der Ideallage beim Verbinden oder beim Lösen der Steckverbindung wird manchmal durch eine Führung eingeschränkt. Diese Führung ist in Gehäuseteile oder dergleichen integriert. Bei Handbetätigung des Steckverbinders, also Verbinden oder Lösen der Steckverbindung mittels Einsatzes der Hand durch den Bediener, hat diese entsprechend genau zu erfolgen.These components are rigid components, which are each connected in particular to a housing part or even have a housing-forming function. Therefore, the components when plugging and unplugging, ie when connecting and disconnecting, must be moved relatively close to each other. The deviation from the ideal position when connecting or when releasing the connector is sometimes limited by a guide. This guide is integrated in housing parts or the like. In manual operation of the connector, so connect or disconnect the connector by using the hand by the operator, this has to be done accordingly accurately.
Eine Überschreitung der zulässigen Lageabweichung beim Verbinden oder beim Lösen der Steckverbindung hat zur Folge, dass Steck- und Ziehkräfte erhöht sind, insbesondere infolge Reibung. Somit wird ein erhöhter Abrieb an den Führungselementen, eine Verformung der Kontaktteile, der Kontaktstifte und/oder der Kontaktfedern bewirkt, wobei die Verformung der Kontaktteile zur Zerstörung der Steckverbindung führen kann.Exceeding the permissible positional deviation when connecting or when releasing the connector has the consequence that plugging and pulling forces are increased, in particular due to friction. Thus, an increased abrasion of the guide elements, a deformation of the contact parts, the contact pins and / or the contact springs is effected, wherein the deformation of the contact parts can lead to the destruction of the connector.
Beim Stand der Technik sind die Komponenten der Steckverbindung in unterschiedlichen Gehäuseteilen untergebracht. Ist eine Steckverbindung nicht mittig angeordnet, so können die Steckverbinderteile durch Verkanten beim Trennen oder Stecken der Verbindung leicht beschädigt werden. Dieser Effekt ist um so gefährlicher, je größer der Abstand von durch die Steckverbindung verbundenen Leiterplatten ist.In the prior art, the components of the connector are housed in different housing parts. If a connector is not centered, then the connector parts can be easily damaged by tilting when disconnecting or plugging the connection. This effect is all the more dangerous, the greater the distance between connected by the connector printed circuit boards.
Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, einen Steckverbindung weiterzubilden, der kostengünstig herstellbar ist und einen geringen Verschleiß beim Öffnen und Schließen aufweist.The invention is therefore the object of developing a connector that is inexpensive to produce and has low wear during opening and closing.
Erfindungsgemäß wird die Aufgabe bei dem Steckverbindung nach den in Anspruch 1 angegebenen Merkmalen gelöst.According to the invention the object is achieved in the connector according to the features specified in
Wesentliche Merkmale der Erfindung bei der Steckverbindung sind, dass sie ein erstes Steckverbinderteil, das mit einem ersten Teil starr verbunden ist, und ein zweites Steckverbinderteil, das mit einem zweiten Teil starr verbunden ist, umfasst, wobei das zweite Steckverbinderteil eine um einen zweiten Drehpunkt drehbar gelagerte Komponente umfasst, wobei beim und nach dem Zusammenführen der beiden Steckverbinderteile zum Herstellen der Verbindung ein erster Drehpunkt wirksam wird, um welchen das erste Steckverbinderteil in der Komponente drehbar ist, und wobei dieser erste Drehpunkt beim weiteren Zusammenführen seine relative Lage und/oder seinen relativen Abstand zum ersten oder zweiten Teil ändert, und wobei beim weiteren Zusammenführen nach dem Wirksamwerden des ersten Drehpunktes elektrische Verbindungen zwischen erstem und zweitem Steckverbinderteil wirksam werden.Essential features of the invention in the connector are that it comprises a first connector part which is rigidly connected to a first part, and a second connector part which is rigidly connected to a second part, wherein the second connector part rotatable about a second pivot point mounted component, wherein during and after the merging of the two connector parts for making the connection, a first pivot point is effective, around which the first connector part is rotatable in the component, and wherein said first pivot further merging its relative position and / or its relative Distance to the first or second part changes, and wherein the further merging after the effective date of the first pivot point electrical connections between the first and second connector part are effective.
Von Vorteil ist dabei, dass ein geringer Verschleiß beim Öffnen, also Trennen, und Schließen, also Stecken, vorhanden ist. Die Betätigung der Steckverbindung ist durch die teilflexible Ausführung verbessert. Dabei sind die Komponenten der Steckverbindung in unterschiedlichen Gehäuseteilen untergebracht. Ist die Steckverbindung nicht mittig angeordnet, so werden die Steckverbinderteile durch Verkanten beim Trennen oder Stecken der Verbindung nicht beschädigt, da die teilflexible Ausführung mit den Drehpunkten eine Kompensation der Abweichungen vorteiligerweise bewirkt. Dieser Effekt ist auch bei großem Abstand von durch die Steckverbindung verbundenen Leiterplatten gegeben.The advantage here is that a low wear during opening, so separating, and closing, so plugging, is present. The operation of the connector is improved by the partially flexible design. The components of the connector are housed in different housing parts. If the connector is not centered, the connector parts are not damaged by tilting when disconnecting or plugging the connection, since the partially flexible design with the pivot points causes a compensation of the deviations advantageous. This effect is given even at a large distance connected by the connector circuit boards.
Wesentlich ist bei der Erfindung auch, dass ein oder beide Steckverbinderteile drehbar und/oder elastisch ausgebildet werden. In Verbindung mit den an der Steckverbindung angeformten Führungen die durch eine geeignete Formgebung der Isolierkörper der Steckverbinderteile erzeugt werden und ein Fangen und Vorpositionieren der Steckverbinderteile bewirken, richten diese Steckverbinderteile sich zueinander aus. Das Ausrichten der Steckverbinderteile verbessert sich durch deren Elastizität oder Drehbarkeit, sodass dadurch eine größerer Lageabweichung beim Schließen und Öffnen der Steckverbindung zulässig wird.It is also essential in the invention that one or both connector parts are rotatable and / or elastic. In conjunction with the integrally formed on the connector guides which are produced by a suitable shaping of the insulating body of the connector parts and cause catching and pre-positioning of the connector parts, these connector parts align with each other. The alignment of the connector parts is improved by their elasticity or rotatability, so that a greater positional deviation when closing and opening the connector is allowed.
Weiterer Vorteil ist, dass durch die teilelastische Ausführung des Steckverbindung in Zusammenwirkung mit dem ersten und zweiten Drehpunkt Montage- und Teiletoleranzen aufgefangen werden. Die Kräfte, die in gestecktem Zustand entstehen, sind somit geringer, wodurch das Material, Kontakte, Isolierkörper, Lötstellen geschont werden.Another advantage is that assembly and part tolerances are absorbed by the partially elastic design of the connector in cooperation with the first and second fulcrum. The forces that arise in the plugged state, are thus lower, whereby the material, contacts, insulators, solder joints are spared.
Die beschriebene erfindungsgemäße Steckverbindung hat somit folgende Vorteile:
- Sie erlaubt eine große Abweichung der Parallelität der Leiterplatten beim Stecken und Ziehen der Leiterplatten und im gesteckten Zustand.
- Sie erlaubt einen Versatz der Federleiste und Stiftleiste in Querrichtung.
- Sie erlaubt eine Verdrehung der Federleiste und Stiftleiste rechtwinklig zur Steckrichtung
- It allows a large deviation of the parallelism of the printed circuit boards during insertion and removal of the printed circuit boards and in the inserted state.
- It allows a displacement of the spring strip and pin header in the transverse direction.
- It allows a rotation of the spring strip and pin header at right angles to the direction of insertion
Somit werden Beschädigungen der Teile der Steckverbindung verhindert. Außerdem sind größere Toleranzen der beteiligten Bauelemente zugelassen, wie beispielsweise Toleranzen der Gehäuseteile oder Leiterplatte und/oder eine Lagetoleranz der Bauelemente auf der Leiterplatte und Montagetoleranz der Leiterplatte im Gehäuse.Thus, damage to the parts of the connector can be prevented. In addition, larger tolerances of the components involved are allowed, such as tolerances of the housing parts or circuit board and / or a positional tolerance of the components on the circuit board and mounting tolerance of the circuit board in the housing.
Insbesondere wird darüber hinaus auch eine schwimmende Befestigung von einem Teil des Verbinders vermieden, wodurch auch die Massekontaktierung vereinfacht wird.In particular, in addition, a floating attachment of a part of the connector is avoided, whereby the ground contact is simplified.

Von Vorteil ist dabei, dass die Erfindung auf verschiedenste Geräte anwendbar ist, beispielsweise auf Netzstecker, elektronische Haushaltsgeräte jeder Art, Computer, Stereoanlagen, industriell eingesetzte Elektronik umfassende Geräte, Umrichter und dergleichen. Wesentlich ist dabei nur, dass das erste Teil mit einem ersten Gehäuseteil und das zweite Teil mit einem zweiten Gehäuseteil verbunden ist. Die beiden Gehäuseteile werden beispielsweise jeweils mit der Hand aufeinanderzubewegt. Die Steckverbindung ist dabei derart ausgeführt, dass sie die Abweichungen von der Ideallage beim Aufeinanderzubewegen oder Voneinanderwegbewegen kompensiert und sowohl keine Beschädigungen der Komponenten auftritt als auch kein erhöhter Verschleiß und/oder Abnutzung.In a preferred embodiment, the first part and the second part are each a housing part or each rigidly connected to a housing part and / or connectable.

The advantage here is that the invention can be used in devices that have electronic circuits or circuit boards for cost-effective connection.

Bei einer bevorzugten Ausführung ist die Federleiste in der Führungsleiste drehbar gelagert. Von Vorteil ist dabei, dass durch geeignete Ausformung die drehbare Lagerung herstellbar ist. Beispielsweise durch eine Ausbildung der Führungsleiste mit an ihrem, der Federleiste zugewandtem Ende hervorstehendem Material, das zusammenwirkt mit einem in der Federleiste vorhandenen Hohlraum zur Aufnahme der Führungsleiste, wobei der Hohlraum derart geformt ist, dass das hervorstehende Material an ihm geführt wird und somit während des Einführens oder Herausbewegens der Führungsleiste der Drehpunkt wirksam ist, insbesondere an verschiedenen Stellen des Hohlraums. Beispielsweise ist ein Hohlraum vorteilhaft verwendbar, der einen rechteckigen Querschnitt aufweist.In a preferred embodiment, the spring bar is rotatably mounted in the guide bar.

Beim und nach dem Zusammenführen der Steckverbindung, also beim Aufeinanderzubewegen der Leiterplatte 53 und Leiterplatte 57, kommt das Steckerteil 56 in Kontakt mit einem Zwischenstück 55 Dabei wird der Drehpunkt 52 wirksam, der durch die entsprechende Ausformung des Steckerteils 56 und des zugehörigen Hohlraums des Zwischenstücks 55 gebildet wird. Relativ zueinander sind Steckerteil 56 und Zwischenstück 55 drehbar. Diese Drehbarkeit ist während des weiteren Aufeinanderzubewegens vorhanden, also ist der Drehpunkt 52 in seiner Position verschiebbar, insbesondere nimmt seine Distanz zur Leiterplatte 53 beim Aufeinanderzubewegen ab.When and after the merge of the connector, so when moving toward each other of the

Aufgabe der Steckverbindung ist es, elektrische Verbindungen zwischen zwei Leiterplatten 4 zu schaffen. Jede dieser Leiterplatten 4 ist in einem Gehäuseteil jeweils montiert. Beim Verbinden der Gehäuseteile soll die Steckverbindung geschlossen werden. Da der Bediener die Gehäuseteile per Hand führt, sind Abweichungen der Gehäuseteile von der Ideallage vorhanden. Diese Abweichungen werden durch die teilflexible Konstruktionsweise des Steckverbindung abgefangen.The task of the connector is to create electrical connections between two
In einen Stiftträger 3 sind Kontaktstifte 2 mit Lötbereichen eingepresst, die in die untere Leiterplatte 4 eingeführt sind und verlötet sind. Die Führungsleiste 5 ist über einen Drehpunkt im Stiftträger 3 gelagert.In a
In die obere Leiterplatte 4 sind Kontaktfedern 7 mit Lötbereichen eingeführt und angelötet. Die Kontaktfedern 7 mit Lötbereichen sind in die Federleiste 6 eingebettet.In the
Beim Schließen, also Stecken, werden die Kontaktstifte 2 mit Lötbereichen in die Kontaktfedern 7 eingeführt und ergeben dann den elektrischen Kontakt.When closing, so plugging, the contact pins 2 are introduced with soldering areas in the contact springs 7 and then give the electrical contact.

Die Verjüngung 22 des Grundkörpers der Federleiste schafft eine Beweglichkeit für die Federleiste in der Führungsleiste. Die Kammer 23 für Federleiste in der Führungsleiste schafft einen Raum für Beweglichkeit der Federleiste. Die Beweglichkeit der Kontaktstifte 2 mit Lötbereichen ist mit dem Bezugszeichen 24 gekennzeichnet. Der Kontaktpunkt 26 der Feder in Längsrichtung

Die Kontaktfeder und der Innenraum der Federleiste sind so gestaltet, dass die Enden der Kontaktstifte Platz für eine Querbewegung haben.
Die Kontaktfeder der Federleiste ist so geformt, dass die Kontaktflächen zum Kontaktstift der Stiftleiste in Längsrichtung angeordnet sind. Die Kontaktfedern müssen bei der Beweglichkeit in Querrichtung keine Kräfte aufnehmenThe contact spring and the interior of the spring bar are designed so that the ends of the contact pins have room for a transverse movement.
The contact spring of the spring strip is shaped so that the contact surfaces are arranged to the contact pin of the pin header in the longitudinal direction. The contact springs must absorb no forces in the transverse movement

In die Federleiste 44 ist der Stiftträger 3 mit Kontaktstiften eingesteckt. Die Führungsleiste 5 ist über ein Drehlager im Befestigungsschuh 42 gelagert, der das Befestigungsloch 43 für eine Befestigungsschraube umfasst, die den Befestigungsschuh auf der Leiterplatte befestigt und darüber hinaus Befestigungsschuh und Leiterplatte im Gehäuseteil befestigt.

In der
Wesentlich ist bei der Erfindung, dass ein oder beide Steckverbinderteile drehbar und/oder elastisch ausgebildet werden. In Verbindung mit den an der Steckverbindung angeformten Führungen die durch eine geeignete Formgebung der Isolierkörper der Steckverbinderteile erzeugt werden und ein Fangen und Vorpositionieren der Steckverbinderteile bewirken, richten diese Steckverbinderteile sich zueinander aus. Das Ausrichten der Steckverbinderteile verbessert sich durch deren Elastizität oder Drehbarkeit, sodass dadurch eine größerer Lageabweichung beim Schließen, also Stecken, und Öffnen, also Trennen, des Steckverbindung zulässig wird.It is essential in the invention that one or both connector parts are rotatable and / or elastic. In conjunction with the integrally formed on the connector guides which are produced by a suitable shaping of the insulating body of the connector parts and cause catching and pre-positioning of the connector parts, these connector parts align with each other. The alignment of the connector parts improves by their elasticity or rotation, so that a larger positional deviation when closing, so plugging, and opening, so disconnecting, the connector is allowed.
Weiterer Vorteil ist, dass durch die teilelastische Ausführung des Steckverbindung in Zusammenwirkung mit dem ersten und zweiten Drehpunkt Montage- und Teiletoleranzen aufgefangen werden. Die Kräfte, die in gestecktem Zustand entstehen, sind somit geringer, wodurch das Material, Kontakte, Isolierkörper, Lötstellen geschont werden.Another advantage is that assembly and part tolerances are absorbed by the partially elastic design of the connector in cooperation with the first and second fulcrum. The forces that arise in the plugged state, are thus lower, whereby the material, contacts, insulators, solder joints are spared.
Das beschriebene System hat die folgenden Vorteile:
- 1. Es erlaubt eine große Abweichung der Parallelität in der Leiterplatten, beim Stecken und Ziehen der Leiterplatten und im gestecktem Zustand.
- 2. Es erlaubt einen Versatz der Federleiste und Stiftleiste in Querrichtung.
- 3. Es erlaubt eine Verdrehung der Federleiste und Stiftleiste rechtwinklig zur Steckrichtung
- 1. It allows a large deviation of the parallelism in the circuit boards, when plugging and unplugging the circuit boards and in the plugged state.
- 2. It allows a displacement of the spring bar and pin header in the transverse direction.
- 3. It allows a rotation of the spring strip and pin header perpendicular to the direction of insertion
Somit werden Beschädigungen der Teile des Steckverbindung verhindert. Außerdem sind größere Toleranzen der beteiligten Bauelemente zugelassen, wie beispielsweise Toleranzen der Gehäuseteile oder Leiterplatte und/oder eine Lagetoleranz der Bauelemente auf der Leiterplatte und Montagetoleranz der Leiterplatte im Gehäuse.Thus, damage to the parts of the connector can be prevented. In addition, larger tolerances of the components involved are allowed, such as tolerances of the housing parts or circuit board and / or a positional tolerance of the components on the circuit board and mounting tolerance of the circuit board in the housing.
Insbesondere wird darüber hinaus auch eine schwimmende Befestigung von einem Teil des Verbinders vermieden, wodurch auch die Massekontaktierung vereinfacht wird.In particular, in addition, a floating attachment of a part of the connector is avoided, whereby the ground contact is simplified.
