An einer Montaqeflache befestigtes elektrisches GerätElectrical device attached to a mounting surface BeschreibungDescription

Die Erfindung betrifft ein an einer Montagefläche, vorzugsweise an einer Leiterplatte, befestigtes elektrisches Gerät mit Kontaktfahnen für den elektrischen Anschluß und mit Haltemitteln zur Befestigung an der Montagefläche.The invention relates to an electrical device attached to a mounting surface, preferably on a circuit board, with contact lugs for the electrical connection and with holding means for attachment to the mounting surface.

Schaltmodule zur Montage auf Leiterplatten oder ähnlichen Montageflächen besitzen für den elektrischen Anschluß Lötfahnen, die in der Leitplatte eingelötet werden und hierdurch bereits einen Beitrag zur Befestigung des elektrischen Geräts an der Montagefläche leisten. Darüberhinaus können zusätzliche Haltemittel vorgesehen sein, wie z. B. Schrauben, Nieten oder dergleichen, welche die Lötverbindungen entlasten und einen sicheren Halt an der Montagefläche gewährleisten. Soll das betreffende Gerät entfernt oder ausgetauscht werden, so ist neben dem Lösen der zusätzlichen Haltemittel auch das Entlöten der Lötverbindungen erforderlich. Switch modules for mounting on circuit boards or similar mounting surfaces have solder lugs for the electrical connection, which are soldered into the circuit board and thus already contribute to securing the electrical device to the mounting surface. In addition, additional holding devices can be provided, such as screws, rivets or similar, which relieve the solder connections and ensure a secure hold on the mounting surface. If the device in question is to be removed or replaced, the solder connections must be desoldered in addition to loosening the additional holding devices.

Es sind andererseits auch elektrische Geräte bekannt, die an Montageflächen, wie z. B. Leiterplatten lösbar angeordnet sind, wobei für den elektrischen Anschluß üblicherweise als Steckkontakte ausgebildete Kontaktfahnen vorgesehen sind, welche in Steckverbindungen eingreifen können, undOn the other hand, electrical devices are also known which are detachably arranged on mounting surfaces, such as circuit boards, whereby contact lugs, usually designed as plug contacts, are provided for the electrical connection, which can engage in plug connections, and

Mp.-Nr. 93/608 2 14. Juli 1993Mp.-No. 93/608 2 14 July 1993

für die Befestigung des jeweiligen Geräts zusätzliche Haltemittel, die gegebenenfalls in Verbindung mit Abstandhaltern die mechanische Verbindung mit der Montagefläche sicherstellen. Additional holding devices for fastening the respective device, which, if necessary in conjunction with spacers, ensure the mechanical connection to the mounting surface.

Bei beiden bekannten Lösungsmöglichkeiten besteht jedoch der Nachteil, daß mehr oder weniger aufwendige Arbeitsabläufe bzw. zusätzliche Teile erforderlich sind, die die Befestigung gewährleisten, was sich nachteilig auf die Herstellkosten und Herstelldauer von solcherart ausgerüsteten elektrischen Komponenten auswirkt.However, both known solutions have the disadvantage that more or less complex work processes or additional parts are required to ensure fastening, which has a negative impact on the manufacturing costs and manufacturing time of electrical components equipped in this way.

Ausgehend von diesem Stand der Technik ist es daher Aufgabe der Erfindung, ein möglichst einfach aufgebautes und leicht montierbares elektrisches Gerät der eingangs genannten Art zu schaffen, bei welchem der Montageaufwand möglichst gering ist.Based on this state of the art, it is therefore the object of the invention to create an electrical device of the type mentioned at the beginning that is as simple as possible in design and easy to assemble, in which the assembly effort is as low as possible.

Erfindungsgemäß besteht die Lösung dieser Aufgabe in den kennzeichnenden Merkmalen des Patentanspruchs 1. Danach ist vorgesehen, daß die Kontaktfahnen zusätzlich mit sogenannten Rastmarken versehen sind, welche zur Befestigung des elektrischen Geräts an der betreffenden Montagefläche dienen. Das elektrische Gerät kann beispielsweise ein ein- oder mehrpoliges Schaltmodul sein, dessen Baugröße es zuläßt, daß es auf einer Montagefläche, wie z. B. auf einer Leiterplatte, angeordnet werden kann. Wie allgemein üblich ist hierbei in der jeweiligen Montagefläche für jede Kontaktfahne eine Ausnehmung vorgesehen, welche von der betreffenden Kontaktfahne durchgriffen wird.According to the invention, this problem is solved by the characterizing features of claim 1. According to this, the contact lugs are additionally provided with so-called locking marks, which serve to attach the electrical device to the relevant mounting surface. The electrical device can be, for example, a single-pole or multi-pole switching module, the size of which allows it to be arranged on a mounting surface, such as a circuit board. As is generally customary, a recess is provided in the respective mounting surface for each contact lug, through which the relevant contact lug passes.

Darüberhinaus kann es erforderlich bzw. vorteilhaft sein, daß an den Kontaktfahnen jeweils auch sogenannte Anschlagmarken vorgesehen sind, welche sich an der Montagefläche anlegen.In addition, it may be necessary or advantageous for the contact lugs to be provided with so-called stop marks, which rest on the mounting surface.

Mp.-Nr. 93/608 3 14. Juli 1993Mp.-No. 93/608 3 14 July 1993

In Weiterbildung der Erfindung können die Anschlagmarken und/oder die Rastmarken durch örtliche Abbiegungen oder Vorsprünge bzw. von entsprechenden Ausnehmungen oder Einformungen an den Kontaktfahnen gebildet sein. Dabei sind die Rastmarken vorzugsweise widerhakenähnlich geformt, so daß sie sich nach Durchgreifen der betreffenden Montagefläche an deren Unter- oder Rückseite anlegen und so das elektrische Gerät lagesicher fixieren.In a further development of the invention, the stop marks and/or the locking marks can be formed by local bends or projections or by corresponding recesses or indentations on the contact lugs. The locking marks are preferably shaped like barbs so that after reaching through the relevant mounting surface they rest on the underside or back of the latter and thus securely fix the electrical device in position.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Anschlagmarken durch stufenförmige Formgebung der Kontaktfahnen gebildet. Dabei können die Stufen sowohl durch Biegung der Kontaktfahne erzeugt sein als auch durch einen entsprechenden Materialüberstand an den Längsseiten der Kontaktfahne, der sich an der einen Seite der Montagefläche anlegt, wohingegen die Rastmarken die gegenüberliegende Seite der Montagefläche beaufschlagen. Hierbei ist es zweckmäßig, den Abstand zwischen den Anschlagmarken und den Rastmarken im Hinblick auf die Dicke der jeweiligen Montagefläche, d. h. zum Beispiel der Leiterplatte, so festzulegen, daß eine gewisse Vorspannung resultiert.According to a preferred embodiment of the invention, the stop marks are formed by a step-like shape of the contact lugs. The steps can be created by bending the contact lug or by a corresponding material overhang on the long sides of the contact lug, which rests on one side of the mounting surface, whereas the locking marks act on the opposite side of the mounting surface. It is expedient to set the distance between the stop marks and the locking marks with regard to the thickness of the respective mounting surface, i.e. for example the circuit board, in such a way that a certain pre-tension results.

Eine andere Ausgestaltung der Rastmarken sieht vor, daß die Kontaktfahnen konisch zulaufende Einformungen aufweisen, die eine Stufe bilden, an welcher sich die jeweilige Montagefläche anlegt. Hierbei sind die darin angeordneten Ausnehmungen für die sie durchgreifenden Kontaktfahnen ausreichend schmal, so daß diese darin eingespannt sind.Another design of the locking marks provides that the contact lugs have conical recesses, which form a step against which the respective mounting surface rests. The recesses arranged in them are sufficiently narrow for the contact lugs that pass through them so that they are clamped in them.

Im übrigen ist gemäß der Erfindung davon Gebrauch gemacht, daß die verwendeten Werkstoffe ein gewisses elastisches Verformungsvermögen aufweisen. Abhängig vom jeweiligen Anwendungsfall ist demgemäß in erfindungsgemäßer Weiterbildung vorgesehen, daß einerseits bei den zur Befestigung dienenden Kontaktfahnen sowie der geräteseitigen Bodenplatte als auch bei den für die Kontaktfahnen vorgesehenenFurthermore, according to the invention, use is made of the fact that the materials used have a certain elastic deformation capacity. Depending on the respective application, it is accordingly provided in a further development according to the invention that on the one hand the contact lugs used for fastening and the base plate on the device as well as the contact lugs provided for

Mp.-Nr. 93/608 4 14. Juli 1993Mp.-No. 93/608 4 14 July 1993

Ausnehmungen in der Montagefläche jeweils deren Rückfederungseigenschaften ausgenutzt werden.Recesses in the mounting surface are used to exploit their springback properties.

Es kann aber auch entsprechend einer anderen Ausgestaltung der Erfindung vorgesehen sein, daß für die Befestigung auch die Möglichkeit einer plastischen bzw. elasto-plastischen Verformung der Montagefläche genutzt wird.However, according to another embodiment of the invention, it can also be provided that the possibility of a plastic or elasto-plastic deformation of the mounting surface is also used for fastening.

Als elektrisches Gerät kommt neben der bereits erwähnten Möglichkeit, daß es ein Schaltgerät sein kann, auch eine Fassung für Leuchtmittel, z. B. Lampen, Dioden und dergleichen in Betracht.In addition to the previously mentioned possibility of a switching device, an electrical device can also be a socket for lighting devices, e.g. lamps, diodes and the like.

Diese und weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.These and further advantageous embodiments of the invention are the subject of the subclaims.

Anhand von in der Zeichnung dargestellten Ausführungsbeispielen sollen die Erfindung, vorteilhafte Ausgestaltungen und Verbesserungen sowie besondere Vorteile der Erfindung näher erläutert und beschrieben werden.The invention, advantageous embodiments and improvements as well as particular advantages of the invention will be explained and described in more detail using embodiments shown in the drawing.

Mp.-Nr. 93/608 5 14. Juli 1993Mp.-No. 93/608 5 14 July 1993

Ferner sind die an der Unterseite des Gehäuses 12 angeordneten Nocken 13 gezeigt, die als Abstandhalter gegenüber einer hier gestrichelt dargestellten als Montagefläche dienenden Leiterplatte 20 sich daran abstützen. Dabei ist die Leiterplatte 20 mit Ausnehmungen 22 versehen, welche von den Kontaktfahnen 16, 18 durchgriffen werden. Die Kontaktfahnen 16, 18 ihrerseits besitzen im gehäusenahen Bereich eine Einformung 17, 19, welche an ihrem Übergang zur normalen Materialdicke der Kontaktfahnen 16, 18 einen Vorsprung als Haltemarke 23 bilden, der auf der dem Gehäuse 12 abgewandten Seite der Leiterplatte 20 diese hintergreift.Furthermore, the cams 13 arranged on the underside of the housing 12 are shown, which support themselves as spacers against a circuit board 20, shown here in dashed lines, which serves as a mounting surface. The circuit board 20 is provided with recesses 22 through which the contact lugs 16, 18 pass. The contact lugs 16, 18 in turn have a recess 17, 19 in the area close to the housing, which at their transition to the normal material thickness of the contact lugs 16, 18 form a projection as a holding mark 23, which engages behind the circuit board 20 on the side facing away from the housing 12.

Eine besondere Form der Ausnehmungen 22 ist aus Figur 1 ersichtlich. Die Ausnehmungen 22 sind so geformt, daß die Federeigenschaften des Materials genutzt werden können, um einen Festsitz des Gerätes 10 sicherzustellen. Bei Montage des Gerätes werden die Schnapplaschen 24, 25 der Montageplatte 20 in einer entsprechenden Vorrichtung so unterstützt, daß sie nach einstecken des Gerätes dieses zwischen Nocken 13 und Haltemarke 23 unter Vorspannung halten.A special form of the recesses 22 can be seen in Figure 1. The recesses 22 are shaped in such a way that the spring properties of the material can be used to ensure that the device 10 is firmly seated. When the device is mounted, the snap tabs 24, 25 of the mounting plate 20 are supported in a corresponding device in such a way that after the device has been inserted, they hold it under pre-tension between the cam 13 and the holding mark 23.

In Figur 2 ist das elektrische Gerät 10 in Seitenansicht dargestellt, welches ein Gehäuse 12 besitzt, das mit einer an seiner Oberseite angeordneten Betätigungs- oder Anzeigeeinrichtung 14 versehen ist und an der gegenüberliegenden Unterseite rechtwinklig zueinander versetzt angeordnete Kontaktfahnen 16, 18 aufweist.Figure 2 shows a side view of the electrical device 10, which has a housing 12 provided with an actuating or display device 14 arranged on its upper side and has contact lugs 16, 18 arranged at right angles to one another on the opposite lower side.

Figur 3 zeigt als Detail einen Teil des Geräts 10, das an die Leiterplatte 20 angesetzt ist, wobei die zur Befestigung vorgesehenen Kontaktfahnen 16, 18 in die hierfür vorgesehenen Ausnehmungen 22 eingeführt sind, aber mit ihrem Vorsprung 23 diese noch nicht hintergreifen. In dieser Position sind die Kontaktfahnen 16, 18 elastisch aufeinanderzu gedrückt. Nach endgültiger Verrastung federn sie entsprechend Figur 2 wieder zurück.Figure 3 shows a detail of part of the device 10 that is attached to the circuit board 20, with the contact lugs 16, 18 intended for fastening being inserted into the recesses 22 provided for this purpose, but their projection 23 does not yet engage behind them. In this position, the contact lugs 16, 18 are elastically pressed towards one another. After final locking, they spring back again as shown in Figure 2.
