Aus der DE 10 2004 020 422 A1 ist ein Pin zur elektrischen lötfreien Verbindung mit einer Leiterplatte bekannt, mit einem Einpressbereich, der in ein Leiterplattenloch elastisch und plastisch zur Anpassung an den Lochdurchmesser verformbar ist. Für das Einsetzen des Pins ist ein Einpresswerkzeug vorgesehen, das den Pin führt und versteift.From the DE 10 2004 020 422 A1 a pin for electrical solderless connection with a printed circuit board is known, with a press-in area which is elastically and plastically deformable into a PCB hole to adapt to the hole diameter. For inserting the pin, a press-in tool is provided, which leads and stiffens the pin.

Häufig werden dauerhafte Verbindungen eines Verbindungselementes mit einer Leiterplatte genutzt, wie beispielsweise Nietverbindungen. Bei solchen Varianten, die Schraub- oder Lötverbindungen nutzen, um Verbindungselemente mit Leiterplatten lösbar zu verbinden, wird sowohl zum Anbringen als auch zum Entfernen des Elementes spezielles Werkzeug benötigt. Häufig ist das entfernte Verbindungselement, aufgrund zerstörender Demontage, nicht für eine zweite Nutzung geeignet.Frequently permanent connections of a connecting element are used with a printed circuit board, such as riveted joints. In such variants, which use screw or solder joints to releasably connect fasteners to circuit boards, special tool is needed both for attaching and for removing the element. Often, the removed connector is not suitable for a second use due to destructive disassembly.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verbindungselement so auszubilden, dass eine sichere Kontaktierung eines elektrischen Leiters mittels eines elektrischen Kontaktes auf einer Leiterplatte ohne Zuhilfenahme von Werkzeug gewährleistet wird. Ferner soll eine zerstörungsfreie Demontage des Verbindungselementes von der Leiterplatte zum Austausch und zur Wiederverwendung des Verbindungselementes und der Leiterplatte möglich sein.The invention is therefore based on the object, a connecting element in such a way that a secure contacting of an electrical conductor is ensured by means of an electrical contact on a circuit board without the aid of tools. Furthermore, a non-destructive disassembly of the connecting element of the circuit board for replacement and reuse of the connecting element and the circuit board should be possible.

Diese Aufgabe wird dadurch gelöst, dass der elektrische Kontakt einen hülsenartigen Kontaktbereich aufweist, welcher in einen Durchbruch in der Leiterplatte einsetzbar ist, und mittels Einsetzen eines Klemmstifts in den hülsenartigen Kontaktbereich radial mit der Innenfläche des Durchbruchs verklemmt wird, und dass der elektrische Kontakt einen Anschlussbereich mit einem Anschlussteil zur Befestigung des elektrischen Leiters aufweist.This object is achieved in that the electrical contact has a sleeve-like contact region, which is insertable into an opening in the printed circuit board, and is clamped radially by means of insertion of a clamping pin in the sleeve-like contact region with the inner surface of the opening, and that the electrical contact a connection area having a connection part for fixing the electrical conductor.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 9 angegeben.Advantageous embodiments of the invention are specified in claims 2-9.

Bei der Erfindung handelt es sich um ein elektrisches Verbindungselement, bestehend aus einem elektrischen Kontakt, einem Gehäuse und einem Klemmstift. Der elektrische Kontakt weist einen Kontaktbereich und einen Anschlussbereich auf. Eine Kontaktierung auf einer Leiterplatte geschieht durch Einsetzen des Kontaktbereiches in einen Durchbruch in der Leiterplatte, wobei zumindest die Innenfläche des Durchbruches mit einer elektrische Kontaktfläche versehen ist. Vorzugsweise ist die elektrische Kontaktfläche L-förmig umlaufend am Durchbruch angeordnet, so dass auch um den Durchbruch auf der Leiterplatte eine elektrische Kontaktierung möglich ist.In the invention is an electrical connection element consisting of an electrical contact, a housing and a clamping pin. The electrical contact has a contact region and a connection region. A contact on a circuit board is done by inserting the contact area in a breakthrough in the circuit board, wherein at least the inner surface of the opening is provided with an electrical contact surface. Preferably, the electrical contact surface is L-shaped circumferentially disposed on the opening, so that even the breakthrough on the circuit board electrical contacting is possible.

Der elektrische Kontakt des Verbindungselementes ist im Kontaktbereich als hülsenartiger Teil mit einer bauchigen Ausformung versehen und weist mindestens einen axialen Schlitz auf. Dieser hülsenartige Kontaktbereich verjüngt sich beim Einsetzen in einen Durchbruch elastisch in axialer Richtung im Durchmesser und nimmt bei korrektem Sitz annähernd seine Ursprungsform wieder an. In diesem Zustand wird der Klemmstift in den Kontaktbereich eingefügt, wodurch sich der Kontaktbereich mit der Innenfläche des Durchbruches verklemmt. Eine Kontrolle der elektrischen Kontaktierung ist nicht nötig, da sich der Klemmstift nur bei korrektem Sitz des Kontaktes im Durchbruch in den Kontakt einfügen lässt. Somit kann ein optimaler Sitz und eine sichere Kontaktierung des Verbindungselementes mit der Leiterplatte gewährleistet.The electrical contact of the connecting element is provided in the contact area as a sleeve-like part with a bulbous shape and has at least one axial slot. This sleeve-like contact area tapers when inserted into a breakthrough elastically in the axial direction in diameter and assumes a correct seat approximately its original shape again. In this state, the clamping pin is inserted into the contact area, whereby the contact area is jammed with the inner surface of the opening. It is not necessary to check the electrical contact, as the terminal pin can only be inserted into the contact when the contact is seated correctly. Thus, an optimal fit and secure contact of the connecting element with the circuit board ensured.

Zur Demontage des Verbindungselementes muss lediglich der Klemmstift aus dem Kontaktbereich gezogen, oder von der Gegenseite herausgedrückt, werden. Der Kontakt kann dann aus dem Durchbruch und von der Leiterplatte entfernt werden.To disassemble the connecting element, only the clamping pin has to be pulled out of the contact region, or pushed out from the opposite side. The contact can then be removed from the aperture and from the circuit board.

Die rein elastischen Verformungen des Kontaktbereiches bei Anbringung und Demontage von der Leiterplatte machen es möglich, das Verbindungselement auszutauschen und/oder in einem anderen Durchbruch wiederzuverwenden.The purely elastic deformations of the contact area during mounting and dismounting of the printed circuit board make it possible to replace the connecting element and / or reuse it in another breakthrough.

Die Demontage hat somit keinen Einfluss auf den mechanischen Sitz des Verbindungselementes auf einer anderen Leiterplatte bei erneuter Verwendung.The disassembly thus has no effect on the mechanical seat of the connecting element on another printed circuit board when reused.

In einer vorteilhaften Weiterbildung des Klemmstiftes besitzt dieser an der Außenfläche eine schraubenförmige Anformung. Diese hat den Zweck, den Klemmstift aus dem Kontaktbereich unter zur Hilfenahme eines Schraubendrehers zu schrauben. Zum Anbringen wird der Stift weiterhin einfach in den Kontaktbereich gedrückt.In an advantageous development of the clamping pin this has on the outer surface of a helical Anformung. This has the purpose of screwing the clamping pin out of the contact area with the aid of a screwdriver. For attachment, the pin is still simply pressed into the contact area.

Ein sich im Anschlussbereich des elektrischen Kontaktes befindlicher Anschlussteil, für den Anschluss eines elektrischen Leiters, kann verschiedene Ausführungsformen aufweisen. Neben einer einfachen Fläche oder Öse zum Anlöten des elektrischen Leiters, ist vorteilhaft, den Anschlussteil als eine zum Crimpen ausgeformte Anformung im Anschlussbereich zu gestalten. An dieser kann ein elektrischer Leiter mit einem normalen Crimpwerkzeug fest mit dem elektrischen Kontakt verbunden werden.A connection part located in the connection region of the electrical contact, for the connection of an electrical conductor, can have various embodiments. In addition to a simple surface or eyelet for soldering the electrical conductor, it is advantageous to make the connection part as a molding formed for crimping in the connection region. At this an electrical conductor with a normal crimping tool can be firmly connected to the electrical contact.

Vorteilhafte Möglichkeiten zur Herstellung des elektrischen Kontaktes sind, diesem im Tiefziehverfahren oder als gestanzt und gerolltes Teil zu fertigen.Advantageous possibilities for producing the electrical contact are to manufacture this by deep-drawing or stamped and rolled part.

Es ist vorgesehen den Kontakt im Anschlussbereich mit einem elektrisch nicht leitfähigen Gehäuse zur Isolierung zu ummanteln. Dieses weist eine Aussparung auf, durch welche der Klemmstift in den Kontaktbereich eingefügt werden kann. Eine bevorzugte Ausbildungsform ist, den Anschlussbereich einschließlich des kontaktierenden Endes des elektrischen Leiters zu umspritzen. Auch ist ein Umgießen des Anschlussbereiches oder eine Variante aus zwei einzelnen, zusammenfügbaren Teilen denkbar.It is envisaged to encase the contact in the connection area with an electrically non-conductive housing for insulation. This has a recess through which the clamping pin can be inserted into the contact area. A preferred embodiment is to overmold the terminal area including the contacting end of the electrical conductor. An encapsulation of the connection area or a variant of two individual, joinable parts is also conceivable.

Zur sicheren Übertragung von Strömen mit bis zu 40 A ist eine weitere zweckmäßige Ausbildung, die Kontaktfläche zwischen dem elektrischen Kontakt und der Leiterplatte zu vergrößern. Hierzu ist der elektrische Kontakt im Kontaktbereich mit einer Auflagefläche versehen, die flach auf der Kontaktfläche auf der Leiterplatte aufliegt. Die Auflagefläche weist über den Kreisring verteilte, radial ausgebildete, erhabene Kontaktstreifen auf, die auf der Leiterplatte kontaktieren. Dies ist vor allem dann zweckmäßig, wenn das Verbindungselement auf anderen Kontaktplatten oder Blechen montiert wird, die eine flächendeckende, metallische Oberfläche zur Kontaktierung aufweisen.For safe transmission of currents up to 40 A is a further appropriate training to increase the contact area between the electrical contact and the circuit board. For this purpose, the electrical contact is provided in the contact area with a support surface which is flat on the contact surface rests on the circuit board. The support surface has distributed over the annulus, radially formed, raised contact strips, which contact the circuit board. This is particularly useful when the connecting element is mounted on other contact plates or sheets, which have a nationwide, metallic surface for contacting.

In einer anderen bevorzugten Ausbildungsform ist auch der Anschlussbereich des elektrischen Kontaktes hülsenartig ausgebildet, jedoch mit einem größeren Durchmesser als der Kontaktbereich, der in den Durchbruch in der Leiterplatte eingefügt wird. Auf der Innenseite des Anschlussbereiches befindet sich eine Einschnürung, hinter welcher eine tellerförmige Anformung des Klemmstifts verrastet. Eine zweite tellerförmige Anformungen am Kopf des Klemmstifts ist vorgesehen, um ein einfaches Entfernen des Klemmstifts zu ermöglichen.In another preferred embodiment, the terminal region of the electrical contact is sleeve-like, but with a larger diameter than the contact area, which is inserted into the opening in the circuit board. On the inside of the connection area is a constriction, behind which engages a plate-shaped Anformung the clamping pin. A second plate-shaped projections on the head of the clamping pin is provided to allow easy removal of the clamping pin.

Weiterhin ist vorgesehen, Verbindungselemente in einem Positionierrahmen auf einer Leiterplatte zu montieren. Dieser kann so ausgebildet werden, dass mehrere Verbindungselemente gleichzeitig aufgenommen werden können. Am Positionierungsrahmen vorgesehene Kodierstifte vermeiden eine Fehlsteckung der Montagerichtung.Furthermore, it is provided to mount fasteners in a positioning frame on a circuit board. This can be designed so that a plurality of connecting elements can be added simultaneously. On the positioning frame provided coding pins avoid misfitting the mounting direction.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch das Verbindungselement eine sichere Kontaktierung gewährleistet ist und eine Montage ohne Einsatz von Werkzeug, bei Bedarf sogar mit nur einer Hand, möglich ist.
