Abstract

Known contact elements, which connect a conductor to at least one contact spot on a printed-circuit board, depend on a screwing and soldering process and are not guided during fitment on to a printed- circuit board and during soldering. A contact element (1) which avoids the aforementioned disadvantages consists of a base body (2) with a quadrilateral cross-section. On one end, the base body has at least two mutually opposite spring arms (3). On the other end, the base body merges into at least two contact tabs (7) provided with constrictions (9). The drawing shows a side elevation of a contact element (1) in the completely installed state on a printed-circuit board (14). <IMAGE>

Description

Die Neuerung betrifft ein Kontaktelement für die elektrische Verbindung eines Leiters mit mindestens einer Leiterplatte.The innovation relates to a contact element for the electrical connection of a conductor to at least one printed circuit board.

Kontaktelemente zur Verbindung eines Leiters mit Kontaktflecken beispielsweise Leiterbahnen einer Leiterplatte sind in einer Vielzahl von Aus­führungsformen bekannt. Beispielsweise gibt es einen Abzweiger, der jeweils seitlich zwei Ansätze aufweist, in die eine Leiterplatte eingeschoben werden kann. An einer dritten Seite ist ein Schraubkontakt vorgesehen, so daß der Innenleiter eines Kabels in den Abzweiger eingesteckt werden kann und mit dem Schraubkontakt befestigt werden kann. Die Ansätze werden mit den zugeordneten Kontaktflecken der Leiterplatte in einem Lötvorgang verlötet. Dieser Abzweiger hat den Nachteil, daß er relativ aufwendig zu montieren ist und zu­sätzlich Verschraubungen benötigt.Contact elements for connecting a conductor to contact pads, for example conductor tracks of a printed circuit board, are known in a large number of embodiments. For example, there is a tap that has two lugs on each side into which a circuit board can be inserted. A screw contact is provided on a third side, so that the inner conductor of a cable can be inserted into the tap and can be fastened with the screw contact. The approaches are soldered to the associated contact pads of the circuit board in a soldering process. This tap has the disadvantage that it is relatively complex to assemble and requires additional screw connections.

Es ist weiterhin ein Kontaktelement bekannt (DE-OS 33 01 361), das aus einer tulpenförmigen Kontaktfeder mit diametral angeordneten Halte­beinen besteht. Über die Haltebeine wird das Kontaktelement mit Leiterbahnen einer Leiter­platte elektrisch und mechanisch durch Löten verbunden. Das bekannte Kontaktelement hat den Nachteil, daß die Haltebeine gelötet werden müssen und daß eine Führung des Kontaktelementes beim Aufbringen auf die Leiterplatte fehlt.A contact element is also known (DE-OS 33 01 361), which consists of a tulip-shaped contact spring with diametrically arranged holding legs. The contact element is connected electrically and mechanically to a printed circuit board by soldering using the holding legs. The known contact element has the disadvantage that the holding legs have to be soldered and that there is no guidance of the contact element when it is applied to the printed circuit board.

Der Neuerung liegt die Aufgabe zugrunde, ein Kontaktelement für die elektrische Verbindung eines Leiters mit mindestens einem Kontaktflecken auf einer Leiterplatte zu schaffen, das kleine Abmessungen aufweist, einfach zu montieren ist und auch für lötfreie Verbindungen geeignet ist.The innovation is based on the task of creating a contact element for the electrical connection of a conductor with at least one contact pad on a printed circuit board, which has small dimensions, is easy to assemble and is also suitable for solderless connections.

Diese Aufgabe wird neuerungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst.According to the innovation, this object is achieved by the characterizing features of the main claim.

Dadurch, daß das Kontaktelement einen hülsen­förmigen Grundkörper mit viereckigem Querschnitt aufweist, der an seinem einen Ende in mindestens zwei mit vorgegebenem Abstand sich gegenüber­liegenden Federarme und an seinem anderen Ende in mindestens zwei mit Einschnürungen versehene Kontaktlappen übergeht, kann es einerseits mit den Federarmen auf die Leiterplatte geschoben werden, wobei die Leiterplatte zwischen den Federarmen liegt, und andererseits kann der Innenleiter eines Kabels in die Lappen eingescho­ben werden, wobei durch die Einschnürungen der Kontaktlappen die notwendige Spannung für die elektrische Verbindung vorgegeben wird. Da keine Verschraubungen notwendig sind, kann das Kontaktelement sehr klein ausgeführt werden, wobei durch die kurze Verbindung zwischen den Kontaktstellen der Federarme mit den Kontaktflächen und dem Kabel nur kleine Induktivitäten gegeben sind. Da aufgrund der Federarme keine Verlötungen vorgesehen werden müssen, kann das Kontaktelement beispielsweise beim Schwallöten nicht durch Flußmittel verun­reinigt werden, wodurch die elektrische Ver­bindung beeinträchtigt würde, sondern es ist möglich, das Kontaktelement später auf die Leiterplatte zu schieben.Characterized in that the contact element has a sleeve-shaped base body with a square cross-section, which at one end merges into at least two spring arms opposite one another with a predetermined distance and at its other end into at least two contact tabs provided with constrictions, it can on the one hand with the spring arms onto the circuit board can be pushed, with the circuit board between the spring arms, and on the other hand, the Inner conductor of a cable are inserted into the tabs, the necessary voltage for the electrical connection being predetermined by the constrictions of the contact tabs. Since no screw connections are necessary, the contact element can be made very small, the short connection between the contact points of the spring arms with the contact surfaces and the cable giving only small inductances. Since no soldering has to be provided due to the spring arms, the contact element cannot be contaminated by flux, for example during wave soldering, as a result of which the electrical connection would be impaired, but it is possible to push the contact element onto the printed circuit board later.

Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich. Dadurch, daß die Federarme mit Zähnen versehen sind, wird die elektrische Verbindung zwischen Kontaktelement und Kontaktflecken verbessert. Besonders vor­teilhaft ist, daß seitlich an dem hülsenförmigen Grundkörper jeweils zwei Vorsprünge angeordnet sind, die einen der Dicke der Leiterplatte ent­sprechenden Abstand zueinander aufweisen, da diese Vorsprünge eine Führungsfunktion aus­üben, wenn das Kontaktelement in einem in der Leiterplatte vorgesehenen Schlitz eingesteckt wird. Dadurch, daß der hülsenförmige Grundkörper bedingt durch das Herstellungsverfahren ge­schlitzt ist, ist auch ein Kontaktlappen unter Bildung von zwei Teilen geschlitzt, so daß es drei Kontaktstellen zu dem in das Kontakt­element eingeschobenen Innenleiter des Kabels gibt.Advantageous further developments and improvements are possible through the measures specified in the subclaims. The fact that the spring arms are provided with teeth, the electrical connection between the contact element and contact pads is improved. It is particularly advantageous that two projections are arranged on the side of the sleeve-shaped base body, which have a spacing from one another corresponding to the thickness of the printed circuit board, since these projections perform a guiding function when the contact element is inserted into a slot provided in the printed circuit board. Characterized in that the sleeve-shaped base body is slotted due to the manufacturing process, a contact tab is slotted to form two parts, so that it there are three contact points to the inner conductor of the cable inserted into the contact element.

Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird in der nach­folgenden Beschreibung näher erläutert. Es zeigen:

  • Fig. 1 eine seitliche Ansicht des Kontaktelementes,
  • Fig. 2 eine Ansicht von hinten, d.h. der Verbindungsstelle zu dem Kabel,
  • Fig. 3a eine Ansicht auf das Kontakt­element von oben gesehen und in einer ersten Ausführungsform,
  • Fig. 3b eine Ansicht wie in Fig. 3a einer zweiten Ausführungsform, und
  • Fig. 4 eine Ansicht des Kontaktelementes mit Kabel im auf die Leiterplatte aufgeschobenen Zustand.
An embodiment of the innovation is shown in the drawing and is explained in more detail in the following description. Show it:
  • 1 is a side view of the contact element,
  • 2 is a view from the rear, ie the connection point to the cable,
  • 3a is a view of the contact element seen from above and in a first embodiment,
  • Fig. 3b is a view as in Fig. 3a of a second embodiment, and
  • Fig. 4 is a view of the contact element with cable in the state pushed onto the circuit board.

Das Kontaktelement 1 gemäß den Fig. 1 bis 3 weist einen hülsenförmigen Grundkörper 2 auf, der einen rechteckigen Querschnitt hat. Der Grundkörper 2 geht in Federarme 3 über, die sich gegenüberstehen und zwischen sich einen Abstand bilden, der etwa kleiner ist als die Leiter­platte mit den entsprechenden Kontaktflecken 15 (Fig. 4). Die Federarme weisen Zähne auf, die zur Verbesserung der Kontaktierung beitragen. Wie aus Fig. 3a und 3b ersichtlich ist, sind die Federarme 3 mit Einschnitten 5 versehen, wodurch sich jeder Federarm 3 in zwei Teilarme 6 aufteilt. Dadurch wird die Federwirkung der Federarme verbessert und die Möglichkeit einer größeren Anzahl von Kontaktstellen gegeben. An dem den Federarmen 3 entgegengesetzten Ende ist der Grundkörper 2 an den vier Ecken ge­schlitzt, so daß sich vier Lappen ergeben. Nach Fig. 3 dienen jeweils zwei sich gegenüber­liegende Lappen als Kontaktlappen 7 und als Führungslappen 8. Die Kontaktlappen sind erst nach innen gebogen und anschließend schräg nach außen, so daß sich eine Einschnürung 9 ergibt. Die Führungslappen 8 sind ebenfalls nach außen abgebogen. An den die Führungslappen 8 aufweisenden Seitenflächen des hülsenförmigen Grundkörpers 2 sind jeweils zwei punktartige Vorsprünge 10 vorgesehen, die zwischen sich einen Abstand aufweisen, der der Dicke der Leiterplatte entspricht. Diese Vorsprünge 10 dienen zur Führung des Kontaktelementes an der Leiterplatte. In einer alternativen Ausführungs­form (Fig. 3b) des Grundkörpers 2 weist dieser vier Kontaktlappen 7 auf, deren Einschnürungen 9, 9a paarweise axial hintereinanderliegen.The contact element 1 according to FIGS. 1 to 3 has a sleeve-shaped base body 2, which has a rectangular cross section. The base body 2 merges into spring arms 3 which face each other and form a distance between them which is approximately smaller than the printed circuit board with the corresponding contact pads 15 (Fig. 4). The spring arms have teeth that help improve contacting. As can be seen from FIGS. 3a and 3b, the spring arms 3 are provided with incisions 5, as a result of which each spring arm 3 is divided into two partial arms 6. This improves the spring action of the spring arms and gives the possibility of a larger number of contact points. At the end opposite the spring arms 3, the base body 2 is slotted at the four corners, so that there are four tabs. According to FIG. 3, two opposite tabs each serve as contact tabs 7 and as guide tabs 8. The contact tabs are first bent inwards and then obliquely outwards, so that a constriction 9 results. The guide tabs 8 are also bent outwards. On the side surfaces of the sleeve-shaped base body 2 which have the guide tabs 8, two point-like projections 10 are provided, which have a distance between them which corresponds to the thickness of the printed circuit board. These projections 10 serve to guide the contact element on the circuit board. In an alternative embodiment (FIG. 3b) of the base body 2, it has four contact tabs 7, the constrictions 9, 9a of which are axially one behind the other in pairs.

Das Kontaktelement wird aus gewalztem Blech ge­bogen, wodurch herstellungsbedingt ein Längs­schlitz 11 vorhanden ist. Dieser Längsschlitz wird derart angeordnet, daß er einen Kontakt­lappen 7 mittig aufteilt, so daß sich zwei Teil­lappen 12 ergeben. Durch diese Maßnahme wird die Kontaktierung der Kontaktlappen 7 mit dem Innenleiter des Kabels verbessert, da drei Kontaktstellen zur Verfügung stehen.The contact element is bent from rolled sheet metal, so that a longitudinal slot 11 is present due to the manufacturing process. This longitudinal slot is arranged such that it divides a contact tab 7 in the middle, so that two partial tabs 12 result. This measure will Contacting the contact tab 7 with the inner conductor of the cable improved, since three contact points are available.

Fig. 4 zeigt ein mit einem Kabel 13 versehenes Kontaktelement 1, das auf eine Leiterplatte 14 mit Kontaktflecken 15 geschoben ist. In der Leiterplatte ist ein Schlitz 16 vorgesehen, wobei in der Nähe des Endes des Schlitzes die Kontaktflecken 15 beginnen. Die Breite des Schlitzes 16 in der Leiterplatte entspricht in etwa der Breite des Kontaktelementes 1, während die Dicke der Leiterplatte 14 etwa dem Abstand zwischen den Vorsprüngen 10 ent­spricht. Auf diese Weise wird sowohl eine seitliche Führung als auch eine Führung in der Höhe ermöglicht. Am Ende der Leiterplatte 14 weitet sich der Schlitz etwas auf, so daß die Führungslappen 8 ebenfalls zur Führung des Kontaktelementes 1 dienen können. Die Zähne 4 der Federarme 3 krallen sich in die Kontakt­flecken 15 ein, so daß eine gute elektrische Verbindung gegeben ist. Der Innenleiter 16 des Kabels 13 wird lediglich in das Kontakt­element eingesteckt, wobei sich die Kontakt­lappen 7 etwas auseinanderdrücken und die Ein­schnürungen 9 unter Spannung auf dem Innen­leiter liegen.FIG. 4 shows a contact element 1 provided with a cable 13, which is pushed onto a printed circuit board 14 with contact spots 15. A slot 16 is provided in the circuit board, with the contact pads 15 beginning near the end of the slot. The width of the slot 16 in the printed circuit board corresponds approximately to the width of the contact element 1, while the thickness of the printed circuit board 14 corresponds approximately to the distance between the projections 10. In this way, lateral guidance as well as guidance in height is made possible. At the end of the circuit board 14, the slot widens somewhat, so that the guide tabs 8 can also serve to guide the contact element 1. The teeth 4 of the spring arms 3 claw into the contact spots 15, so that a good electrical connection is given. The inner conductor 16 of the cable 13 is merely inserted into the contact element, the contact tabs 7 pressing apart somewhat and the constrictions 9 lying on the inner conductor under tension.
