Description

Die Erfindung betrifft ein Kontaktbauelement mit einem Anschlußteil, der einen Anschlußpunkt zum Verbinden mit einem Anschlußelement aufweist, und einem Kontaktteil, für den Gegenkontakt des Anschlußelements, wobei das Kontaktbauelement in einem Basisgehäuseteil einer ersten Baueinheit zusammen mit wenigstens einem weiteren gleichartigen Kontaktbauelement in einem vorgegebenen rasterförmigen Teilungsabstand bedarfsentsprechend voneinander beabstandet einsetzbar ist und für das wie auch für die anderen Kontaktbauelemente in einer weiteren, mit der ersten Baueinheit steckverbindbaren zweiten Baueinheit jeweils ein Gegenkontakt in räumlich damit übereinstimmender Anordnung vorhanden ist, wobei die Kontaktbauelemente mit den Anschlußelementen verbindbar sind, die elektrischen Baugruppen oder Bauelemente zugehörig sind und die in ihrer räumlichen Anordnung zueinander oder in ihrer Position in der zu steckenden zweiten Baueinheit von den Gegenkontakten abweichen, mit denen sie bestimmungsgemäß zu verbinden sindThe invention relates to a contact component with a connection part, which has a connection point for connecting to a connection element, and a contact part, for the mating contact of the connection element, the contact component in a base housing part of a first structural unit together with at least one further similar contact component at a predetermined grid-shaped pitch can be used at a distance from one another as required and for the other contact components, as well as for the other contact components, there is a counter contact in a spatially corresponding arrangement in a further second unit which can be plug-connected to the first unit, the contact components being connectable to the connection elements, the electrical assemblies or components are associated and which differ in their spatial arrangement to one another or in their position in the second structural unit to be inserted from the mating contacts with which they are to be connected as intended

In elektrischen Anlagen besteht die Notwendigkeit, bestimmte Baueinheiten miteinander lösbar zu verbinden, um elektrische Verbindungen zwischen ihnen bzw. zwischen den in ihnen jeweils enthaltenen Funktionseinheiten herzustellen. Dies erfolgt in der Weise, daß die eine Baueinheit entsprechende Kontaktelemente enthält, die mit den an der jeweils anderen Baueinheit dazu fluchtend vorgesehenen Gegenkontaktelementen in Eingriff gebracht werden. Es ist beispielsweise üblich, eine Baueinheit mit Kontaktstiften zu versehen, die in einem bestimmten Teilungsabstand angeordnet sind. Die damit steckverbindbaren Gegenkontakte der jeweils anderen Baueinheit müssen dann die Funktion einer Steckbuchse erfüllen. Diese Gegenkontakte sind ihrerseits wiederum mit Abschlußelementen von in der Baueinheit enthaltenen Baugruppen bzw. Bauelementen verbunden. Für diese Anschlußelemente die z.B. drahtartige Anschlußstifte darstellen, ist üblicherweise eine bestimmte Anschlußkonfiguration vorgegeben. Diese kann von derjenigen abweichen, die für diejenigen Kontaktelemente besteht, mit denen sie z.B. durch Löten oder durch Klemmen zu verbinden sind. Bei Vorliegen einer solchen Abweichung ist eine unmittelbare Verbindung nur dadurch möglich, daß zusätzliche Maßnahmen getroffen werden. Dies ist insbesondere im Hinblick auf eine automatisierte Montage solcher Baueinheiten von Nachteil. Um eine solche bestehende Abweichung in der Konfiguration der zu verbindenden Anschlüsse auszugleichen, ist eine Zwischenebene in Form einer zusätzlichen Leiterplatte die entsprechend angepaßte Abschlußelemente aufweist, möglich. Eine andere Lösung würde darin bestehen, die Anschlußelemente zur Ausrichtung auf ihre jeweils zugehörigen Anschlußpunkte zu verformen und gegebenenfalls entsprechend ausgerichtete Führungsbahnen vorzusehen.In electrical systems, there is a need to releasably connect certain structural units to one another in order to establish electrical connections between them or between the functional units contained in them. This takes place in such a way that the one structural unit contains corresponding contact elements which are brought into engagement with the mating contact elements provided in alignment with the other structural unit. For example, it is customary to provide a structural unit with contact pins which are arranged at a certain pitch. The mating contacts of the other assembly that can be plugged in must then perform the function of a socket. These counter contacts are in turn connected to terminating elements of assemblies or components contained in the structural unit. A specific connection configuration is usually specified for these connection elements, which represent, for example, wire-like connection pins. This can deviate from that which exists for those contact elements with which they are to be connected, for example by soldering or by clamping. If there is such a deviation, a direct connection is only possible by taking additional measures. This is particularly disadvantageous with regard to the automated assembly of such structural units. In order to compensate for such an existing deviation in the configuration of the connections to be connected, an intermediate level in the form of an additional printed circuit board which has appropriately adapted terminating elements is possible. Another solution would be to deform the connection elements to align them with their associated connection points and, if necessary, to provide correspondingly aligned guideways.

Es ist die Aufgabe der Erfindung bei unterschiedlichen Konfigurationsverhältnissen zwischen den zu verbindenden Teilen eine flexible Anpassung zu ermöglichen.It is the object of the invention to enable flexible adaptation in the case of different configuration relationships between the parts to be connected.

Dies wird dadurch erreicht, daß für den zur Verbindung mit den Anschlußelementen vorgesehenen Anschlußpunkt des Kontaktbauelementes, bezogen auf die in Steckrichtung verlaufende Symmetrieachse seines mit dem Gegenkontakt fluchtend zu kontaktierenden Kontakteils sowohl in einer zur Symmetrieachse senkrecht verlaufenden Richtung als auch in der dazu und auch zur Symmetrieachse senkrecht verlaufenden Richtung ein bestimmter Versatz festgelegt ist, daß das Kontaktbauelement einstückig ausgebildet ist und ein rechteckförmig oder U-förmig ausgebildetes Basisteil aufweist, das in Steckrichtung als das mit dem Gegenkontakt jeweils zu kontaktierenden Kontaktteil und in Steckrichtung in der dem Kontaktteil abgewandten Richtung als das mit dem genannten Versatz für den Anschlußpunkt versehene Anschlußteil ausgestaltet ist, und daß jedes Kontaktbauelement bei gleichbleibender Steckrichtung in unterschiedlichen Positionen in dem Basisgehäuseteil lagegesichert einsetzbar ist, so daß durch die Wahl der Position der eingesetzten Kontaktbauelemente zueinander die Anschlußpunkte variabel in eine mit der Lage der Anschlußelemente übereinstimmenden Lage bringbar sind.This is achieved in that for the connection point of the contact component provided for connection to the connection elements, based on the axis of symmetry of its contact part to be aligned with the mating contact in the plugging direction, both in a direction perpendicular to the axis of symmetry and in the direction thereof and also to the axis of symmetry a certain offset is defined in the perpendicular direction, that the contact component is formed in one piece and has a rectangular or U-shaped base part, which in the plug-in direction as the contact part to be contacted with the mating contact and in the plug-in direction in the direction facing away from the contact part as with the said offset for the connection point provided connecting part is designed, and that each contact component can be used with the same direction of insertion in different positions in the base housing part so that you can Through the choice of the position of the contact components used with respect to one another, the connection points can be variably brought into a position which corresponds to the position of the connection elements.

Es ist also möglich, mit dem erfindungsgemäß an dem Kontaktteil - das also einerseits einen Anschlußpunkt bzw. Anschlußbereich für ein Anschlußelement und andererseits ein Kontaktteil zur Steckverbindung mit einem entsprechenden Gegenkontakt aufweist-realisierten Versatz in einfacher Weise eine Umsetzung von einer Konfiguration in eine davon abweichende Konfiguration zu erzeugen, so daß zu verbindende Anschlußpunkte in eine zueinander fluchtende Lage gebracht werden. Nur durch die Auswahl der Position von völlig identisch ausgestalteten Kontaktbauelementen für die eine gewisse Abstimmung auf die angewendeten Teilungsabstände besteht, ist generell eine Umsetzung von einem Raster auf ein davon abweichendes Raster möglich oder auch eine Umsetzung einer linienförmig ausgerichten Konfiguration auf ein bestimmtes Raster. Auch eine einfache maßliche Anpassung im vorgegebenen Versatz auf einen Teilungsabstand sind also durch das erfindungsgemäße Kontaktbauelement eine Vielzahl von Umsetzungen möglich.It is therefore possible, with the offset realized according to the invention on the contact part - that is, on the one hand a connection point or connection area for a connection element and on the other hand a contact part for the plug connection with a corresponding mating contact - to convert a configuration into a configuration that deviates therefrom to generate so that connection points to be connected are brought into an aligned position. Only by choosing the position of completely identical contact components for the there is a certain degree of coordination with the spacing used, it is generally possible to convert from a grid to a grid that deviates from it, or to convert a linear configuration to a specific grid. A simple dimensional adjustment in the predefined offset to a pitch is also possible with the contact component according to the invention in a large number of implementations.

An der DE-B-1 246 078 ist bereits ein Kontaktbauelement mit Klemmanschlüssen bekannt, das zur Aufnahme unterschiedlich konfigurierter Anschlußenden dient jedoch ist dieses bekannte Kontaktbauelement nicht für den universellen Einsatz in ein Basisgehäuseteil einer Steckvorrichtung geeignet. Das gleiche gilt auch für das aus "IBM Technical Disclosure Bulletin, Vol. 7, No. 1, June 1964" bekannte Kontaktbauelement.From DE-B-1 246 078 a contact component with terminal connections is already known, which serves to accommodate differently configured connection ends, however, this known contact component is not suitable for universal use in a basic housing part of a plug-in device. The same also applies to the contact component known from "IBM Technical Disclosure Bulletin, Vol. 7, No. 1, June 1964".

Grundsätzlich kann das genannte Kontaktteil als Kontaktstift oder als Buchse ausgebildet sein. Die letztgenannte Funktion wird beispielsweise mit der Ausbildung des Kontaktteils als Gabelfederkontakt erzielt. Durch die U-förmige Ausbildung des Basisteils kann es mit diesem Bereich problemlos in einer entsprechend angepaßten Aufnahmekammer des für die betreffende Baueinheit vorgegebenen Basisgehäuseteils in einer bestimmten verdrehungssicheren Position eingesetzt werden. Dies kann in um jeweils 90° gegeneinander gedrehten Positionen erfolgen.In principle, the mentioned contact part can be designed as a contact pin or as a socket. The latter function is achieved, for example, by designing the contact part as a fork spring contact. Due to the U-shaped design of the base part, it can be used with this area without any problems in a correspondingly adapted receiving chamber of the base housing part specified for the structural unit in question in a certain rotationally secure position. This can be done in positions rotated 90 ° against each other.

Gemäß einer Weiterbildung der Erfindung ist das Anschlußteil als Klemmanschluß ausgestaltet. Zu seiner Herstellung wird die nach oben weitergeführte eine Seitenfläche des Basisteils als assymetrisch verbreiterter Ansatz ausgebildet, dessen oberer Endbereich eine in ihrer Lage durch den Versatz in der einen Richtung definierte Ausnehmung aufweist. Im Bereich dieser Ausnehmung ist dieser Endbereich soweit spitzwinklig in sich zurückgebogen, daß das Anschlußelement zur Herstellung einer Klemmverbindung durch die genannte Ausnehmung zwischen die durch das Zurückbiegen gebildeten Schenkel einschiebbar ist und die untere Kante des zurückgebogenen Schenkels in den Anschlußstift eindrückt und damit die Klemmverbindung ermöglicht.According to a development of the invention, the connecting part is designed as a terminal connection. For its manufacture, the upwardly extended one side surface of the base part is designed as an asymmetrically widened extension, the upper end region of which has a recess defined in its position by the offset in one direction. In the area of this recess, this end region is bent back so far at an acute angle that the connecting element for producing a clamp connection can be inserted through the recess mentioned between the legs formed by the bending back and presses the lower edge of the bent back leg into the connecting pin and thus enables the clamp connection.

Der Klemmanschluß des einstückig ausgebildeten Kontaktbauelementes ist also aus einem Federblech gleicher Materialstärke durch einfache Stanz-Biege-Vorgänge herstellbar. Zur Führung eines als Anschlußstift ausgebildeten Anschlußelementes ist in den nicht zurückgebogenen Schenkel des Anschlußteils eine Sicke eingedrückt, so daß insbesondere bei einer automatisierten Montage die Ausrichtung zum eigentlichen Klemmpunkt hin erfolgt.The terminal connection of the one-piece contact component can thus be produced from a spring plate of the same material thickness by simple stamping and bending processes. In order to guide a connecting element designed as a connecting pin, a bead is pressed into the leg of the connecting part which is not bent back, so that the alignment with the actual clamping point takes place in particular in the case of automated assembly.

Gemäß einer weiteren Ausbildung der Erfindung hat der den genannten Versatz in zwei Richtungen aufweisende Anschlußpunkt des Anschlußteils vom Basisteil einen bestimmten Abstand. Dadurch ist nach dem Einsetzen des Kontaktbauelementes im Bereich des Basisteils der jeweilige Anschlußteil frei zugänglich.According to a further embodiment of the invention, the connection point of the connection part having the said offset in two directions is at a certain distance from the base part. As a result, the respective connection part is freely accessible after the contact component has been inserted in the region of the base part.

  • FIGS. 5 to 8 show details of the use of the contact component according to the invention in a protective plug which can be plugged onto a distributor strip having the respective mating contacts.

Den Figuren 1 bis 3 ist zu entnehmen, daß das dargestellte Ausführungsbeispiel des Kontaktelementes ausgehend von einem U-förmig ausgebildeten Basisteil ein als Klemmanschluß gestaltetes Anschlußteil 3 und an der diesem abgewandten anderen Ende einen Gabelfederkontakt aufweist, mit dem das Kontaktbauelement 1 auf einen als Gegenkontakt dienenden Kontaktstift aufsteckbar ist. Die Schenkel 6a und 6b die eine unmittelbare Verlängerung der einander gegenüberliegenden Seitenwände des Basisteils 5 darstellen, laufen aufeinander zu und bilden die Kontaktstelle 7.It can be seen from FIGS. 1 to 3 that the exemplary embodiment of the contact element shown, starting from a U-shaped base part, has a connecting part 3 designed as a clamp connection and, at the other end facing away from it, has a fork spring contact with which the contact component 1 serves as a mating contact Contact pin can be plugged on. The legs 6a and 6b an immediate extension of the represent opposite side walls of the base part 5, run towards each other and form the contact point 7.

Der in Weiterführung des Basisteils 5 nach oben gebildete Anschlußteil in Form des Klemmanschlusses 3 entsteht dadurch, daß dieser Teil in sich zurückgebogen ist. In dem Biegebereich ist eine vorab als Langloch vorzugebende Ausnehmung 8 vorgesehen, durch den ein z.B. als Anschlußstift ausgebildetes Anschlußelement zwischen die durch das Zurückbiegen gebildeten Schenkel einschiebbar ist. Zur besseren Führung eines solchen Anschlußstiftes ist ein Sicke 9 vorgesehen, wobei dann die Tiefe dieser dadurch gebildeten Führungsrille geringer als der Durchmesser des betreffenden Anschlußstiftes ist. Der eigentliche Klemmpunkt 4 des Klemmanschlusses 3 ist in zwei zueinander senkrechten Richtungen bezogen auf die Symmetrieachse 2 des Gabelfederkontaktes um den Abstandswert v1 bzw. v2 versetzt. Der eigentliche Klemmpunkt 4 weist von den oberen Begrenzungskanten des Basisteils 5 einen bestimmten Abstand auf wie in den Figuren 1 bzw. 2 zu entnehmen ist. Dadurch wird sichergestellt, daß nach dem Einsetzen des Kontaktbauelementes 1 in eine entsprechend an sein Basisteil angepaßte Aufnahmekammer der Klemmanschluß problemlos zugänglich bleibt. Mit dem Steg 10a, 10b der beim Einsetzen z.B. in einen entsprechend daran angepaßten Einschnitt eingeführt wird, kann sich das Bauelement in Einsteckrichtung abstützen. Bezogen auf diese Richtung ist dieser Einschnitt jeweils am oberen Rand der Kammerwände angebracht.The connection part formed in the continuation of the base part 5 in the form of the clamp connection 3 arises from the fact that this part is bent back in itself. In the bending area there is a recess 8 to be predetermined as an elongated hole, through which a e.g. can be inserted as a connecting pin between the legs formed by the bending back. A bead 9 is provided for better guidance of such a connecting pin, in which case the depth of the guide groove formed thereby is less than the diameter of the relevant connecting pin. The actual clamping point 4 of the clamping connection 3 is offset in two mutually perpendicular directions with respect to the axis of symmetry 2 of the fork spring contact by the distance value v1 or v2. The actual clamping point 4 is at a certain distance from the upper boundary edges of the base part 5, as can be seen in FIGS. 1 and 2. This ensures that after inserting the contact component 1 into a receiving chamber which is appropriately adapted to its base part, the terminal connection remains easily accessible. With the web 10a, 10b which e.g. is inserted into a correspondingly adapted incision, the component can be supported in the insertion direction. In relation to this direction, this incision is made on the upper edge of the chamber walls.

Die jeweiligen Aufnahmekammern befinden sich in einem Basisgehäuseteil einer Baueinheit, die dann diejenigen Baugruppen bzw. Bauelemente enthält, deren z.B. als Anschlußstifte ausgebildeten Anschlußelemente über den Klemmanschluß in einer vorgegebenen Zuordnung mit dem Kontaktbauelement verbunden werden müssen. Die an einer Baugruppe bzw. an einem Bauelement vorgesehenen Anschlußstifte weisen eine ganz bestimmte räumliche Konfiguration zueinander auf. In der Regel stimmt diese nicht mit derjenigen Konfiguration überein, die für die als Gegenkontakte vorbestimmten Kontaktstifte - z.B. aus bestimmten konstruktiven Gründen - vorgegeben ist. Zur Herstellung der Steckverbindung zwischen dieser Baueinheit und der erstgenannten Baueinheit sind jedoch die eine solche Verbindung ermöglichenden Teile, also im Ausführungsbeispiel die Kontaktstifte und die Gabelfederkontakte, fluchtend zueinander ausgerichtet.The respective receiving chambers are located in a base housing part of a structural unit, which then contains those assemblies or components whose connecting elements, for example designed as connecting pins, must be connected to the contact component in a predetermined assignment via the terminal connection. The connection pins provided on an assembly or on a component have a very specific spatial configuration with respect to one another. As a rule, this does not match the configuration that is specified for the contact pins predetermined as counter-contacts, for example for certain design reasons. To establish the plug connection between them The assembly and the first-mentioned assembly, however, align the parts that enable such a connection, that is to say in the exemplary embodiment the contact pins and the fork spring contacts, in alignment with one another.

In den mit dem Bezugszeichen a bis f versehenen Darstellungen der FIG 4 sind schematisch einige prinzipielle Möglichkeiten angegeben, bei denen durch das erfindungsgemäße Kontaktbauelement 1 eine vorgegebene Geometrie der genannten Anschlußstifte in eine davon abweichende Geometrie der Gegenkontakte für das Kontaktbauelement umgesetzt werden können. Es läßt sich damit also die Funktion eines Umsetzsteckers von Anschlußkonfigurationen z.B. auf Stiftraster realisieren. Damit kann dann z.B. bei Abschlußsteckern, bei Kurzschlußbrücken und dergleichen eine unmittelbare Anpassung der Anschlußstifte ihrer darin enthaltenen Bauteile auf die z.B. als Gabelfederkontakte ausgebildeten Steckkontakte erfolgen. In der FIG 4 sind nur einige Umsetzmöglichkeiten beispielhaft genannt. In Abhängigkeit von den Gegebenheiten des jeweiligen Anwendungsfalles sind die Kontaktelemente in verschiedenen Positionen in die Aufnahmekammern einer Basisplatte einzusetzen, für die wiederum ein bestimmtes Raster in der räumlichen Zuordnung dieser Aufnahmekammer zueinander gegeben ist. In den Beispielen nach der FIG 4 wird symbolisch die Lage der Anschlußstifte von Baugruppen bzw. von Bauelementen durch einen kleinen Kreis und die gleichfalls konstruktionsbedingt feststehende Lage der Gegenkontakte und damit übereinstimmend die Lage der Kontaktstellen durch ein X symbolisch gekennzeichnet. Darüber hinaus ist zumindest für die Darstellungen a und b die jeweilige Position der eingesetzten Kontaktbauelemente in Übereinstimmung mit der Ansicht nach der FIG 3 symbolisch eingezeichnet.In the representations of FIG. 4 provided with the reference numerals a to f, some basic possibilities are schematically indicated, in which the contact component 1 according to the invention can be used to convert a given geometry of the mentioned connection pins into a different geometry of the mating contacts for the contact component. The function of a conversion plug of connection configurations, e.g. realize on pin grid. It can then e.g. in the case of terminating plugs, short-circuit bridges and the like, a direct adaptation of the connecting pins of their components contained therein to the e.g. Plug contacts designed as fork spring contacts. In FIG 4 only a few implementation options are mentioned as examples. Depending on the circumstances of the respective application, the contact elements are to be inserted in different positions in the receiving chambers of a base plate, for which in turn there is a certain grid in the spatial assignment of this receiving chamber to one another. In the examples according to FIG. 4, the position of the connecting pins of assemblies or of components is symbolically identified by a small circle and the position of the mating contacts, which is also fixed by design, and symbolically the position of the contact points by an X. In addition, at least for the representations a and b, the respective position of the contact components used is drawn symbolically in accordance with the view according to FIG. 3.

Bei der Darstellung nach der FIG 4 a wird eine Anpassung von einem durch vier Anschlußstifte vorgegebenem Raster auf ein davon abweichendes Gegenkontaktraster vorgenommen. Die einzelnen erfindungsgemäßen Kontaktbauelemente sind - wie der Schemazeichnung entnehmbar ist - abwechselnd jeweils um 90° gegeneinandergedreht eingesetzt. Bei der in der FIG 4 b dargestellten Konfigurationwerden Anschlußstifte, die in einem bestimmten Abstand zueinander in einer geraden Linie angeordnet sind, in eine Rasteranordnung für die Gegenkontakte umgesetzt. Die Kontaktelemente sind dabei gegeneinander um 180° gedrent eingesetzt. Betrachtet man beispielsweise die drei untersten Kontaktelemente, so könnte damit eine Umsetzung von einer linienförmigen Anordnung auf eine dreiecksförmige Anordnung vorgenommen werden, wobei dann die Gegenkontakte bzw. die Kontaktelemente des Kontaktbauelementes 1 an den Eckpunkten dieses Dreiecks angeordnet sind.In the representation according to FIG. 4 a, an adaptation is made from a grid specified by four connecting pins to a mating contact grid that differs therefrom. The individual contact components according to the invention are - as can be seen from the schematic drawing - used alternately in each case rotated by 90 ° with respect to one another. In the case shown in FIG. 4b Configuration, connection pins, which are arranged at a certain distance from one another in a straight line, are converted into a grid arrangement for the mating contacts. The contact elements are used against each other by 180 °. If, for example, the three lowest contact elements are considered, a conversion from a linear arrangement to a triangular arrangement could be carried out, in which case the mating contacts or the contact elements of the contact component 1 are arranged at the corner points of this triangle.

In ännlicher Weise kann dann gemäß FIG 4 c eine Anpassung von Gegenkontakten, die in einer Linie angeordnet sind, auf die in dem angegebenen Raster angeordneten Anschlußstifte vorgenommen werden. Die Kontaktbauelemente werden abwechseln um 180° gegeneinandergedreht in Linie eingesetzt.In a similar manner, an adaptation of mating contacts, which are arranged in a line, to the connection pins arranged in the specified grid can then be carried out according to FIG. 4c. The contact components are used alternately turned by 180 ° in line.

Durch die symbolische Darstellung der FIG 4 d wird gezeigt, daß zwei Reihen von Anschlußstiften auf zwei Reihen von untereinancer einen geringeren Abstand aufweisenden Gegenkontaktreihen anzupassen sinc. Die Kontaktbauelemente sind innerhalb einer Gegenkontaktreine in gleicher Position einsetzbar, wobei die Kontaktbauelemente der einen Reihe gegenüber der anderen Reihe um 180° gedreht sind.The symbolic representation of FIG. 4 d shows that two rows of connecting pins can be matched to two rows of mating contact rows having a smaller distance from one another. The contact components can be used in the same position within a mating contact line, the contact components of one row being rotated by 180 ° with respect to the other row.

Durcn die Darstellung der FIG 4 e wird angedeutet, daß eine Reihe von geradlinig ausgerichteten Anschlußstiften auf eine andere Reihe von in gleicher Weise geradlinig ausgerichteten Gegenkontakten anzupassen ist. Die FIG 4 f zeigt eine andere Konfiguration von zwei Anschlußstiftreihen und zwei Gegenkontaktreihen.The representation of FIG. 4e indicates that a row of rectilinearly aligned connecting pins has to be adapted to another row of mating contacts that are rectilinearly aligned in the same way. FIG. 4 f shows another configuration of two rows of pins and two rows of mating contacts.

Durch eine bestimmte Positionierung des erfindungsgemäßen Kontaktbauelementes ergeben sich über die dargestellten Umsetzungen hinaus weitere Umsetzmöglichkeiten. In den FIG 5 bis 8 ist die Anwendung des erfindungsgemäßen Kontaktbauelementes 1 bei einem Schutzstecker 12 gezeigt. Ein solcher Schutzstecker ist beispielsweise für eine Verteilerleiste erforderlich, um Überspannungen an Leitungsadern, die über die Verteilerleiste durchverbunden werden, abzuleiten. Unter der Voraussetzung eines separaten Schutzsteckers 12 für ein Leitungsadernpaar ist hierzu für diesen Schutzstecker eine Ankontaktierungsmöglichkeit an jede der beiden Adern und an eine Erdverbindung erforderlich. Bei der perspektivischen Darstellung nach der FIG 6 sind dies die Kontaktstifte 14...16, die bedienungsseitig aus der Verteilerleiste 13 herausragen. Diese Kontaktstifte bzw. Kontaktmesser sind aus konstruktiven Gründen, die sich unter anderem aus den für den Aufbau der Leiste verwendeten Teilen ergeben, auf der Bedienungsseite derart einander zugeordnet, daß sie an den Eckpunkten eines Dreieckes liegen. Zwei von den drei insgesamt vorhandenen Anschlußstiften, die diese Dreiecks-Konfiguration bilden, sind in unmittelbarer Nähe der einen Außenkante der Leiste plaziert.A specific positioning of the contact component according to the invention results in further implementation options beyond the implementations shown. 5 to 8 show the use of the contact component 1 according to the invention a protective plug 12 shown. Such a protective plug is required, for example, for a distribution strip in order to discharge overvoltages on cable cores which are connected through the distribution strip. Provided that a separate protective plug 12 is used for a pair of line wires, this protective plug must be able to be connected to each of the two wires and to an earth connection. In the perspective view according to FIG. 6, these are the contact pins 14... 16, which protrude from the distribution strip 13 on the operator side. These contact pins or contact blades are assigned to one another on the operating side in such a way that they lie at the corner points of a triangle for constructional reasons, which result, inter alia, from the parts used for the construction of the strip. Two of the three total connecting pins that form this triangular configuration are located in the immediate vicinity of the one outer edge of the strip.

Die eine von den beiden miteinander steckzuverbindenden Einheiten stellt somit in diesem Anwendungsfall eine Verteilerleiste dar, während die andere Baueinheit den Schutzstecker bildet. Um diese Steckverbindung unmittelbar zu ermöglichen, sind demnach im Schutzstecker die mit den Kontaktstiften 14...16 zu kontaktierenden Kontaktteile in gleicher Zuordnung zueinander eingebracht. Das bedeutet, daß die in der Explosionsdarstellung des Schutzsteckers nach der FIG 5 angedeuteten Aufnahmekammern für die betreffenden Kontaktbauelemente die gleiche Konfiguration zueinander haben, wie die Kontaktstifte 14...16. Die Aufnahmekammern bzw. die Kontaktelemente sind also hinsichtlich ihrer mit den Kontaktstiften zu kontaktierenden Kontaktteile (Gabelfederkontakt) in der gleichen Dreiecksform plaziert. Die Anschlußstifte 21 des Überspannungsableiters 29, die mit den Kontaktbauelementen 1 zu verbinden sind, liegen jedoch in einer geraden Linie in Längsrichtung des Überspannungsableiters 19. Bei Verwendung von normalen Kontaktelementen, die also nicht erfindungsgemäß ausgestaltet sind und bei denen üblicherweise der Anschlußpunkt in der Symmetrieachse der steckzuverbindenden Kontaktteile liegt, müßte zur Anpassung eine entsprechende Verformung der Anschlußstifte 21 vorgenommen werden. Dies ist bei Anwendung des erfindungsgemäßen Kontaktbauelementes 1 nicht erforderlich.The one of the two units to be plugged together thus represents a distribution strip in this application, while the other unit forms the protective plug. In order to enable this plug-in connection directly, the contact parts to be contacted with the contact pins 14... 16 are introduced in the same assignment to one another in the protective plug. This means that the receiving chambers indicated in the exploded view of the protective plug according to FIG. 5 for the relevant contact components have the same configuration to one another as the contact pins 14 ... 16. The receiving chambers or the contact elements are therefore placed in the same triangular shape with regard to their contact parts (fork spring contact) to be contacted with the contact pins. However, the connection pins 21 of the surge arrester 29, which are to be connected to the contact components 1, lie in a straight line in the longitudinal direction of the surge arrester 19. When using normal contact elements, which are therefore not designed according to the invention, and in which usually the If the connection point lies in the axis of symmetry of the contact parts to be plugged in, a corresponding deformation of the connecting pins 21 would have to be carried out. This is not necessary when using the contact component 1 according to the invention.

In den FIG 7 und 8 sind im vergrößerten Maßstab zwei Schnittcarstellungen des gebrauchsfertig bestückten Schutzsteckers 1 dargestellt. Der Klemmpunkt 4 des Anschlußteils 3 ist - wie bereits erwähnt - in zwei zueinander senkrechten Ausrichtungen - bezogen auf die Mittelachse 2 des Gabelfederkontaktes 6 a, 6 b - um den Abstandswert v1 bzw. v2 versetzt. Durch diese spezielle Ausbildung wird es ermöglicht, in die Aufnahmekammern 20a...20c diese völlig gleichartigen Kontaktbauelemente einzusetzen und damit Klemmanschlußpunkte vorzugeben, die in einer geraden Linie angeordnet sind, obwohl die Aufnahmekammern selbst in ihrer Lage zueinander angenähert an den Eckpunkten einer Dreiecksform positioniert sind. Wie beispielsweise der Schnittzeichnung nach der FIG 7 zu entnehmen ist, wird in die Aufnahmekammer 20b und 20c jeweils ein Kontaktbauelement 1 in übereinstimmender Ausrichtung zueinander eingesetzt. Das in die Aufnahmekammer 20a eingesetzte Kontaktbauelement 1 ist demgegenüber in seiner Lage um 180° gedreht. Damit liegen die Klemmpunkte für die Anschlußstifte 21 des Überspannungsableiters 19 in einer geraden Linie, obwohl eine Aufnahmekammer gegenüber den anderen seitlich versetzt angeordnet ist. Es findet also eine Umsetzung der auf den Eckpunkten einer Dreiecksform liegenden Gegenkontaktstellen auf eine geradlinige Anordnung der Anschlußstifte 21 statt. Dies entspricht einer Konfigurationsumsetzung, wie sie auch in der FIG 4 b enthalten ist.7 and 8 show two sectional car positions of the protective plug 1 which is ready for use on an enlarged scale. The clamping point 4 of the connecting part 3 is - as already mentioned - offset in two mutually perpendicular orientations - based on the central axis 2 of the fork spring contact 6 a, 6 b - by the distance value v1 or v2. This special design makes it possible to insert these completely identical contact components into the receiving chambers 20a ... 20c and thus to specify terminal connection points which are arranged in a straight line, although the positions of the receiving chambers themselves are positioned approximately at the corner points of a triangular shape . As can be seen, for example, from the sectional drawing according to FIG. 7, a contact component 1 is inserted into the receiving chamber 20b and 20c in a corresponding alignment with one another. In contrast, the contact component 1 inserted into the receiving chamber 20a is rotated by 180 ° in its position. So that the terminal points for the pins 21 of the surge arrester 19 are in a straight line, although one receiving chamber is laterally offset from the other. There is therefore a conversion of the mating contact points lying on the corner points of a triangular shape to a straight-line arrangement of the connecting pins 21. This corresponds to a configuration implementation, as is also contained in FIG. 4b.

Es ist somit für den Schutz stecker ein handelsüblicher Überspannungsableiter ohne zusätzliche Änderungen in der Ausrichtung seiner Anschlußstifte 21 zu verwenden. Dies ist insbesondere für eine automatisierte Montage eines solchen Schutzsteckers von besonderem Vorteil. Bei einer solchen Montage werden die in FIG 5 ersichtlichen beiden Oberteile 23, 24, die z. B. nach Art eines Filmscharniers mit den oberen Außenkanten des Basisgehäuseteils 22 verbunden sind, gegeneinandergeschwenkt und durch eine vorgesehene Verrastung mechanisch miteinander zu dem geschlossenen Gehäuse für den Schutzstecker verbunden. Beim Aufsetzen des Schutzsteckers 1 auf die Gegenkontaktstifte 14...16 werden die am Basisgehäuseteil 22 vorhandenen Zapfen 17 in entsprechende Öffnungen 18 eingeführt. Es kann dadurch ein unerwünschtes Lösen des aufgesteckten Schutzsteckers verhindert werden. Die gemäß FIG 8 an der Unterkante des Ansatzes 17 vorhandene Noppe hintergreift beim Einsetzen einen entsprechenden Ansatz in der Verteilerleiste. Weiterhin ist dieser FIG zu entnehmen, daß bei dieser Ausführungsform des Schutzsteckers die Gabelfederkontakte des erfindungsgemäßen Kontaktbauelementes 1 völlig geschützt im Basisgehäuseteil 22 angeordnet sind.It is therefore for the protection plug to use a commercially available surge arrester without additional changes in the orientation of its pins 21. This is particularly advantageous for automated assembly of such a protective plug. With such an assembly the two top parts 23, 24 shown in FIG. B. are connected in the manner of a film hinge to the upper outer edges of the base housing part 22, pivoted against one another and mechanically connected to one another to form a closed housing for the protective plug by means of a latching arrangement. When the protective plug 1 is placed on the mating contact pins 14 ... 16, the pins 17 present on the base housing part 22 are inserted into corresponding openings 18. This can prevent an unwanted loosening of the plug. The knob present in FIG. 8 on the lower edge of attachment 17 engages behind a corresponding attachment in the distribution strip when inserted. It can also be seen from this FIG that in this embodiment of the protective plug the fork spring contacts of the contact component 1 according to the invention are arranged in the base housing part 22 in a completely protected manner.
