Description

Die Erfindung betrifft ein Gleitelement zur Kontaktierung von Leiterkarten.The invention relates to a sliding element for contacting printed circuit boards.

Derartige Gleitelemente werden benötigt, um Leiterbahnen von parallel zueinander ausgerichteten, übereinander angeordneten Leiterkarten elektrisch miteinander zu kontaktieren. Dabei sind die Leiterkarten in sehr engem Abstand zueinander angeordnet und weisen eine Vielzahl von Leiterbahnen auf, welche je nach Anwendung und Schaltung unterschiedlich miteinander kontaktiert werden müssen.Such sliding elements are required to electrically contact interconnects of parallel aligned, stacked printed circuit boards. The printed circuit boards are arranged at a very close distance from each other and have a plurality of interconnects, which must be contacted differently depending on the application and circuit.

Je nach Anwendung können mehrere Leiterbahnen der Leiterkarten gleichzeitig durch mehrere Gleitelemente verbunden werden. Durch Verschieben (Gleiten) der Gleitelemente zwischen den Leiterkarten können unterschiedliche Positionen und so unterschiedliche elektrische Verbindungen und Schaltkreise geschlossen werden. Das Gleitelement berührt dabei die beiden Leiterkarten, zwischen welchen es angeordnet ist, mit einem elektrischen Kontakt. So wird eine elektrische Verbindung zwischen der Leiterbahn der einen Leiterkarte und der Leiterbahn der anderen Leiterkarte hergestellt.Depending on the application, a plurality of printed conductors of the printed circuit boards can be connected simultaneously by a plurality of sliding elements. By moving (sliding) the sliding elements between the printed circuit boards different positions and so different electrical connections and circuits can be closed. The sliding element touches the two printed circuit boards, between which it is arranged, with an electrical contact. Thus, an electrical connection between the conductor of a printed circuit board and the conductor of the other printed circuit board is made.

Eine feste Verdrahtung oder Verkabelung ist für derartige Anwendungen z.B. in einem Verteilerkasten für Telefonleitungen nicht zweckmäßig, da die elektrischen Verbindungen von Zeit zu Zeit geändert, ersetzt und neue verkabelt werden müssen. Eine übliche Verkabelung mit Steckverbindern und Kabeln ist dafür sehr aufwendig. Für jede Änderung muss ein Kabel entfernt und an einer anderen Stelle ein Kabel hinzugefügt und elektrische verbunden werden. Für diese Arbeiten muss jeweils ein Mitarbeiter vor Ort an den entsprechenden Verteilerkasten fahren und die neue Verkabelung manuell vornehmen. Dies ist sehr zeit- und kostenintensiv.Hard wiring or cabling is not practical for such applications in, for example, a telephone line junction box because the electrical connections must be changed, replaced, and rewired from time to time. A usual wiring with connectors and cables is very expensive. For each change, a cable must be removed and a cable must be added and electrical connected elsewhere. For this work, one employee has to drive to the respective distribution box on site and make the new wiring manually. This is very time consuming and costly.

Ein weiterer Nachteil bekannter Verkabelungen ist der große Bedarf an Raum. Da die Verkabelungen von Hand getätigt werden, benötigt ein derartiger Schaltschrank für jede mögliche Anschlussposition einen Steckverbinder oder zumindest einen Anschlusspunkt für Litzenleiter. Diese sind sehr groß im Vergleich zu den eigentlichen elektrischen Leitungen die miteinander verbunden werden sollen. Daher wird deutlich mehr Bauraum für eine manuelle Verkabelung benötigt als für die eigentliche, elektrische Kontaktierung nötig wäre.Another disadvantage of known cabling is the great need for space. Since the cabling is done by hand, such a cabinet requires for each possible connection position a connector or at least a connection point for stranded conductors. These are very large in comparison to the actual electrical wires to be connected. Therefore, much more space for a manual wiring is needed than for the actual, electrical contacting would be necessary.

Die US 2013/183872 A1 offenbart eine elektrische Verbindung mit einem elektrisch leitfähigen, komprimierbaren Leitelement. Das komprimierbare elektrische Leitelement beinhaltet einen ersten Leiterendabschnitt und einen zweiten Leiterendabschnitt. Der erste Leiterendabschnitt und der zweite Leiterendabschnitt berühren sich physisch in verschiebbarer Beziehung zueinander bei einer Komprimierung des komprimierbaren elektrischen Leiters, um zumindest teilweise ein Verhindern einer Drehung des komprimierbaren elektrischen Leiters bei einer Komprimierung desselben zu ermöglichen.The US 2013/183872 A1 discloses an electrical connection to an electrically conductive, compressible guide element. The compressible electrical conducting element includes a first conductor end portion and a second conductor end portion. The first conductor end portion and the second conductor end portion physically contact each other in displaceable relationship upon compression of the compressible electrical conductor to at least partially facilitate preventing rotation of the compressible electrical conductor upon compression thereof.

Aus der US 4 664 458 A ist ein Leiterkartensteckverbinder bekannt. Dieser ist so ausgestaltet, dass die Verbindung zwischen Leiterkarten optimiert wird, indem die Verwendung von Abstandshaltern zwischen den Leiterkarten unnötig ist. Dafür weist jeder Kontakt ein C-förmiges Profil mit einer U-förmigen Anformung auf. Die Kontakte sind an festen Positionen im Leiterkartensteckverbinder montiert.From the US 4,664,458 A a printed circuit board connector is known. This is designed to optimize the interconnection between circuit boards by eliminating the need for spacers between the circuit boards. For this, each contact has a C-shaped profile with a U-shaped Anformung. The contacts are mounted at fixed positions in the PCB connector.

In der EP 1 898 497 A2 ist ein Verbinder mit den dazugehörigen Kontakten offenbart. Dieser wird in einem elektronischen Gerät verwendet. Insbesondere bezieht sich die EP 1 898 497 A2 auf die Anordnung von Kontakten in den Durchgangslöchern des Verbinders. Dabei sind mindestens zwei Kontakte von der Vielzahl von Kontakten in jedem der Vielzahl von Durchgangslöchern angeordnet.In the EP 1 898 497 A2 a connector with the associated contacts is disclosed. This is used in an electronic device. In particular, the EP 1 898 497 A2 on the arrangement of contacts in the through holes of the connector. At least two contacts of the plurality of contacts are arranged in each of the plurality of through holes.

Aus der US 5 957 703 A ist ein elektrischer Verbinder bekannt, welcher zwischen zwei Steckverbindern angeordnet ist um diese miteinander zu verbinden, dabei sollen Wischeffekte durch horizontale Bewegungen erzeugt werden, welche einen reinigenden Effekt für den Kontakt haben soll. Ferner sollen der Gleichstromwiderstand und die Herstellkosten verringert werden.From the US 5 957 703 A an electrical connector is known, which is arranged between two connectors to connect them together, while wiping effects are to be generated by horizontal movements, which should have a cleaning effect for the contact. Furthermore, the DC resistance and the manufacturing costs should be reduced.

Die DE12 45 454 A offenbart eine Kontaktfederleiste zum Verbinden wenigstens zweier Schaltungskarten, wobei die Schaltungskarten auf die Nuten der Kontaktfederleiste aufgelegt und dort verschraubt werden.The DE12 45 454 A discloses a contact spring strip for connecting at least two circuit cards, wherein the circuit cards are placed on the grooves of the contact spring strip and screwed there.

Aufgabenstellungtask

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Kontaktierung zweier Leiterkarten vorzustellen. Die Vorrichtung soll dabei variabel zwischen den Leiterkarten beweglich sein und so verschiedene, auf den Leiterkarten vorhandene Leiterbahnen miteinander kontaktieren und verbinden. Die Vorrichtung soll ferner kostengünstig herstellbar und ohne großen Arbeitsaufwand installierbar sein. Zudem wäre es von Vorteil, wenn die Vorrichtung wartungsarm und unempfindlich gegen Fehlfunktionen ist.The object of the invention is to present a device for contacting two printed circuit boards. The device should be variable between the printed circuit boards and thus contact and connect different, present on the printed circuit boards interconnects. The device should also be inexpensive to produce and installable without much work. In addition, it would be advantageous if the device is low maintenance and insensitive to malfunction.

Die Aufgabe wird die Merkmale des unabhängigen Anspruchs 1 gelöst.The object is achieved by the features of independent claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Bei der Erfindung handelt es sich um ein Gleitelement zur elektrischen Kontaktierung von Leiterbahnen, gegenüberliegender Leiterkarten. Dabei sind zwei Leiterkarten parallel, in einem geringen Abstand zueinander angeordnet. Auf der jeweils der anderen Leiterkarte zugewandten Seite sind auf den Leiterkarten elektrische Leiterbahnen vorgesehen. Je nach Anwendung und Verschaltung der beiden Leiterkarten zueinander müssen unterschiedliche, auf den Leiterkarten vorgesehene, gegenüberliegende Leiterbahnen elektrisch miteinander verbunden werden. Zur Lösung dieser Aufgabe ist das erfindungsgemäße Gleitelement vorgesehen.In the invention, it is a sliding element for electrically contacting printed conductors, opposite printed circuit boards. Two circuit boards are parallel, arranged at a small distance from each other. On each of the other circuit board facing Side are provided on the circuit boards electrical traces. Depending on the application and interconnection of the two printed circuit boards to each other, different, provided on the circuit boards, opposite Tracks are electrically connected together. To solve this problem, the sliding element according to the invention is provided.

Das Gleitelement besteht aus einem Grundkörper, welcher aus einem elektrisch nicht leitfähigen Material hergestellt ist. Hier bieten sich Polymere an, da diese eine besonders gute, elektrisch isolierende Wirkung aufweisen. Der Grundkörper des Gleitelements ist zur Aufnahme von zumindest einem elektrischen Kontaktelement vorgesehen.The sliding element consists of a base body, which is made of an electrically non-conductive material. Here are polymers on, since they have a particularly good, electrically insulating effect. The main body of the sliding element is provided for receiving at least one electrical contact element.

Das elektrische Kontaktelement ist dabei vorzugsweise im Grundkörper aufgenommen und befestigt. Dafür verfügt der Grundkörper über Aufnahmen. Die Aufnahmen können z.B. als Schlitz ausgeführt sein. In den Schlitz kann ein Kontaktelement eingesetzt sein. Dabei muss die Aufnahme so ausgebildet sein, dass sie an zwei gegenüberliegenden Seiten des Grundkörpers offen ist. Dadurch wird sichergestellt, dass das Kontaktelement auf zwei gegenüberliegenden Seiten jeweils eine Leiterkarte elektrische kontaktieren kann.The electrical contact element is preferably received and secured in the base body. For this, the main body has recordings. The recordings may e.g. be designed as a slot. In the slot, a contact element may be used. The receptacle must be designed so that it is open on two opposite sides of the body. This ensures that the contact element can contact a printed circuit board electrical on two opposite sides.

In einer bevorzugten Ausführungsform sind im Grundkörper zwei Aufnahmen vorgesehen, die zur Aufnahme von zwei Kontaktelementen dienen.

Vorteil der Nutzung der Gewindebuchse 4 ist jedoch, dass diese einen weit geringeren Verschleiß aufweist, als ein eingeformtes Gewinde im Grundkörper 2. Durch die besseren Materialeigenschaften einer Gewindehülse aus Metall kann das Gewinde länger und öfter benutzt werden, bei deutlich geringeren Verschleißerscheinungen.Advantage of the use of the threaded bushing 4, however, that this has a much lower wear, as a molded thread in the body 2. Due to the better material properties of a threaded metal sleeve, the thread can be used longer and more often, with significantly lower wear.

Auf der, der Gewindebuchse 4 gegenüberliegenden Seite des Grundkörpers 2, sind diesem zwei Aufnahmen 5 eingeformt. Die als Schlitze ausgeführten Aufnahmen 5 erstrecken sich von der Stirnseite des Grundkörpers 2 über fast die gesamte Länge des Grundkörpers 2. Die Aufnahmen 5 sind zur Aufnahme jeweils eines Kontaktelements 3 vorgesehen. Der Übersicht halber ist in der Figur 1 nur eines der beiden Kontaktelemente 3 dargestellt.On the, the threaded bushing 4 opposite side of the base body 2, this two receptacles 5 are formed.

The receptacles 5 are provided for receiving one contact element 3 each. For the sake of clarity is in the FIG. 1 only one of the two contact elements 3 is shown.

Erfindungsgemäß erstrecken sich die Aufnahmen 5 von der hier dargestellten Unterseite des Grundkörpers 2 bis zu der hier dargestellten Oberseite des Grundkörpers 2. Einen Schnitt durch eine der Aufnahmen 5, mit einem darin aufgenommenen Kontaktelement 3 ist in der Figur 2 im Detail gezeigt.According to the invention, the receptacles 5 extend from the lower side of the main body 2 shown here to the upper side of the main body 2 shown here. A section through one of the receptacles 5, with a contact element 3 received therein, is shown in FIG FIG. 2 shown in detail.

Der Schnitt der Figur 2 geht der Länge nach durch eine der Aufnahmen 5. Die Aufnahme 5 im Grundkörper 2 ist dreiseitig offen ausgebildet. An der dargestellten Oberseite, sowie Unterseite ragt das Kontaktelement 3 jeweils aus der Aufnahme 5 auf die Außenseite des Grundkörpers 2. Dies dient der Kontaktierung zweier, über und unter dem Gleitelement 1 angeordneter Leiterkarten 10.The cut of the FIG. 2 goes lengthwise through one of the receptacles 5. The receptacle 5 in the base body 2 is open on three sides. The contact element 3 protrudes from the receptacle 5 onto the outer side of the main body 2 on the illustrated upper side as well as on the underside. This serves to make contact with two printed circuit boards 10 arranged above and below the sliding element 1.

Die links dargestellte Öffnung der Aufnahme 5 ist für die Montage des Kontaktelements 3 in der Aufnahme 5 vorgesehen. Von der dargestellten, linken Seite her kann das Kontaktelement 3 in die Aufnahme 5 eingeführt und in dieser verrastet werden. Dazu befindet sich innerhalb der Aufnahme 5 ein Rastbereich 2.1.The opening shown on the left of the receptacle 5 is provided for the mounting of the contact element 3 in the receptacle 5. From the illustrated, left side, the contact element 3 can be inserted into the receptacle 5 and locked in this. For this purpose, there is a latching area 2.1 within the receptacle 5.

Der Rastbereich 2.1 ist als Steg in der als Schlitz ausgebildeten Aufnahme 5 vorgesehen. Mittig angeordnet, kann das Kontaktelement 3 beidseitig um den Rastbereich 2.1 greifen und an diesem verrastet werden. Das achssymmetrisch ausgebildete Kontaktelement 3 verfügt dafür über zwei Kontaktschenkel 3.3, welche entlang des Rastbereichs 2.1 verlaufen und diesen zwischen sich einschließen.The latching area 2.1 is provided as a web in the slot 5 as recording. Arranged centrally, the contact element 3 can grip on both sides around the latching region 2.1 and be latched thereto. The axisymmetric contact element 3 has for this purpose two contact legs 3.3, which run along the latching area 2.1 and enclose it between them.

Im linken Bereich sind die Kontaktschenkel 3.3 des Kontaktelements 3 miteinander verbunden. Am gegenüberliegenden, rechts dargestellten Ende der Kontaktschenkel 3.3 ist jedem Kontaktschenkel 3.3 eine Befestigungsnase 3.4 angeformt. Diese ist zum jeweils gegenüberliegenden Kontaktschenkel 3.3 zugewandt. Die Befestigungsnasen 3.4 dienen so als Rasthaken mittels welchen das Kontaktelement 3 um den Rastbereich 2.1 greift. Das Kontaktelement 3 rastet so auf dem Rastbereich 2.1 auf und ist so im Grundkörper 2 des Gleitelements 1 gesichert.In the left area, the contact legs 3.3 of the contact element 3 are connected to each other. At the opposite, shown on the right end of the contact leg 3.3 each attachment leg 3.3 a 3.4 attachment nose is formed. This is facing the respective opposite contact legs 3.3. The fastening lugs 3.4 serve as latching hooks by means of which the contact element 3 engages around the latching region 2.1. The contact element 3 engages on the latching area 2.1 and is thus secured in the main body 2 of the sliding element 1.

An die Kontaktschenkel 3.3 des Kontaktelements 3 schließt sich jeweils ein Federarm 3.2 an. Diese sind in diesem Ausführungsbeispiel S-förmig ausgeformt. Durch die S-Form wird ein besonders vorteilhafter Federweg ermöglicht. An den Enden der Federarme 3.2 ist jeweils ein Kontaktpunkt 3.1 ausgebildet. Die Kontaktpunkte 3.1 befinden sich außerhalb des Gehäuses 2 und können so jeweils eine Leiterkarte 10 kontaktieren, welche oberhalb bzw. unterhalb des Gleitelements 1 angeordnet ist.At the contact legs 3.3 of the contact element 3 is followed in each case by a spring arm 3.2. These are S-shaped in this embodiment. Due to the S-shape, a particularly advantageous travel is possible. At the ends of the spring arms 3.2 each have a contact point 3.1 is formed. The contact points 3.1 are located outside the housing 2 and can thus each contact a printed circuit board 10, which is arranged above or below the sliding element 1.

Das Kontaktelement 3 ist vorzugsweise als gestanztes Blechteil ausgeführt. Besonders vorteilhaft ist daran ist, dass dieses nicht gebogen oder in mehreren Ebenen gefertigt ist. Durch den Stanzprozess können sehr feine Konturen dem Blechteil zugefügt werden. Ein Biegeprozess ist immer sehr aufwändig und ungenau. Zudem ist beim Stanzen keine plastische Verformung des Materials nötig, wodurch das Kontaktelement 3 an jeder Stelle seine Festigkeit und Flexibilität, sowie Federeigenschaften beigehält.The contact element 3 is preferably designed as a stamped sheet metal part. It is particularly advantageous is that this is not bent or in is made of several levels. The punching process allows very fine contours to be added to the sheet metal part. A bending process is always very complex and inaccurate. In addition, no plastic deformation of the material is required during the punching, whereby the contact element 3 at any point its strength and flexibility, and spring properties.

In der Figur 2 ist zudem auch die Gewindebuchse 4 im rechten Bereich zu erkennen. Diese ist in die Durchgangsöffnung 6 eingepresst und durch die Rändelung 4.1 an ihrer Außenseite im Gehäuse 2 fixiert. Durch die Gewindebuchse 4 und die Durchgangsöffnung 6 kann eine Gewindestange 11 geführt werden, auf welche das Gleitelement 1 verschiebbar ist.In the FIG. 2 In addition, also the threaded bushing 4 can be seen in the right area. This is pressed into the passage opening 6 and fixed by the knurling 4.1 on its outer side in the housing 2. Through the threaded bushing 4 and the passage opening 6, a threaded rod 11 can be guided, to which the sliding element 1 is displaceable.

Eine Systemanwendung mit mehreren Gleitelementen 1 ist in der Figur 3 gezeigt. Das System besteht dabei aus drei, übereinander angeordneten Leiterkarten 10, 10', 10". Zur besseren Darstellung ist die oberste Leiterkarte 10 nur schematisch dargestellt.A system application with several sliding elements 1 is in the FIG. 3 shown. In this case, the system consists of three printed circuit boards 10, 10 ', 10 "arranged one above the other. For better illustration, the uppermost printed circuit board 10 is shown only schematically.

Zwischen den Leiterkarten 10, 10', 10" ist jeweils ein Trägerrahmen angeordnet. Der Trägerrahmen ist einerseits als Abstandshalter und zur Befestigung der Leiterkarten 10, 10', 10" vorgesehen. Zum anderen sind in den Trägerrahmen mehrere Gewindestangen 11 nebeneinander angeordnet. An der Vorderseite verfügt jede Gewindestange 11 über eine Kupplung - hier schematisch rund dargestellt - die zum Drehen der Gewindestange 11 dient.A carrier frame is in each case arranged between the printed circuit boards 10, 10 ', 10 ".The carrier frame is provided on the one hand as a spacer and for fastening the printed circuit boards 10, 10', 10". On the other hand, a plurality of threaded rods 11 are arranged side by side in the support frame. At the front of each threaded rod 11 has a coupling - shown here schematically round - which serves to rotate the threaded rod 11.

Auf den parallel zueinander angeordneten Gewindestangen 11 ist jeweils ein Gleitelement 1 angeordnet. Auch diese wurden schematisch vereinfach dargestellt. Die Gleitelemente 1 können durch drehen der jeweiligen Gewindestange 11 auf dieser axial bewegt werden. Auf den Leiterkarten 10, 10', 10" vorgesehene Leiterbahnen können so durch die Kontaktpunkte 3.1 der Kontaktelemente 3 der Gleitelemente 1 kontaktiert werden. Eine elektrische Verbindung zwischen den Leiterkarten 10 und 10' oder 10' und 10" wird so erzeugt.On the mutually parallel threaded rods 11 each have a sliding element 1 is arranged. These too were shown schematically simplified. The sliding elements 1 can be moved axially by rotating the respective threaded rod 11 on this. Conductor tracks provided on the circuit boards 10, 10 ', 10 "can thus be contacted by the contact points 3.1 of the contact elements 3 of the sliding elements 1. An electrical connection between the circuit boards 10 and 10' or 10 'and 10 "is generated this way.

Durch die erfindungsgemäße Ausgestaltung der Gleitelemente 1 ist so eine kostengünstig Herstellung und Installation ohne großen Arbeitsaufwand möglich. Zudem ist die Vorrichtung wartungsarm und unempfindlich gegen Fehlfunktionen.The inventive design of the sliding elements 1 as a cost-effective production and installation is possible without much work. In addition, the device is low maintenance and insensitive to malfunction.

Zudem ist ein nach der vorliegenden Erfindung ausgestaltetes System aus einer Vielzahl von Gleitelementen 1 einfach durch eine robotergestützte Vorrichtung bedienbar. So kann ein beweglicher Motor die einzelnen Gewindestangen 11 nacheinander anfahren und durch Drehung die Gleitelemente 1 bewegen. Über eine entsprechende Datenverbindung können so verschiedene elektrische Schaltungen per Fernwartung betätigt werden. Der Einsatz eines Technikers vor Ort ist nicht weiter nötig.In addition, a system of a plurality of sliding elements 1 configured according to the present invention can be easily operated by a robot-supported device. Thus, a moving motor can approach the individual threaded rods 11 one after the other and move the sliding elements 1 by rotation. Via a corresponding data connection so various electrical circuits can be operated by remote maintenance. The use of a technician on site is no longer necessary.
