Description

Die Erfindung bezieht sich auf ein elektrotechnisches Installationsgerät in Modulbauweise, beispielsweise Steckdose, Schalter oder Taster, an dem Teile für zusätzliche Funktionen als steckbare Module an- bzw. einsteckbar ausgeführt sind. Eine derartige Steckdose in der Ausführung als SCHUKO-Steckdose ist bekannt(DE-C2-3 828 177).The invention relates to an electrotechnical installation device in modular construction, for example a socket, switch or push button, on which parts for additional functions are designed as pluggable modules. Such a socket in the version as a SCHUKO socket is known (DE-C2-3 828 177).

Bei der bekannten Beleuchtungs- und Kontrolleinrichtung für eine Schutzkontaktsteckdose erfolgt die Kontaktierung konventionell an einer Platine für Überspannungsschutz.In the known lighting and control device for a protective contact socket, contact is made conventionally on a circuit board for surge protection.

Der Erfindung liegt die Aufgabe zugrunde, allgemein ein elektrotechnisches Installationsgerät in Modulbauweise zu entwickeln, das die steckbaren Module für zusätzliche Funktionen in besonders montagefreundlicher Technik zu kontaktieren ermöglicht.The invention has for its object to generally develop an electrotechnical installation device in modular design, which allows the pluggable modules to be contacted for additional functions in a particularly assembly-friendly technology.

Die Lösung der geschilderten Aufgabe erfolgt nach der Erfindung durch ein elektrotechnisches Installationsgerät nach Patentanspruch 1. Hierbei sind die steckbaren Module für zusätzliche Funktionen durch gefederte Kontaktierung an ohnehin vorhandenen stromführenden Teilen elektrisch kontaktierbar. In der Montage genügt es, das Modul einzustecken, wodurch es zugleich elektrisch kontaktiert wird. Die gefederte Kontaktierung kann durch gefederte Kontakte bzw. Kontaktkörper und bzw. oder durch federnde Stiftaufnahmen erfolgen. Die Stifte sollen ein Stecken ermöglichen und erlauben vielfältige Gestaltung.The object described is achieved according to the invention by an electrotechnical installation device according to claim 1. Here, the plug-in modules for additional functions can be electrically contacted by spring-loaded contacting on current-carrying parts which are already present. In assembly, it is sufficient to insert the module, whereby it is also electrically contacted. The spring-loaded contact can be made by spring-loaded contacts or contact bodies and / or by resilient pin receptacles. The pins are intended to allow insertion and allow a variety of designs.

Für eine Steckdose können die gefederten Kontakte als Schraubenfedern aus elektrisch leitendem Material, beispielsweise aus Federbronze, gebildet sein. Diese können jeweils gegen einführbare Steckerstifte eines Steckers arbeiten. Beim Anschluß eines Steckers wird das Modul dann zugleich elektrisch kontaktiert.For a socket, the spring-loaded contacts can be used as coil springs made of electrically conductive material, for example made of spring bronze. These can each work against insertable plug pins of a plug. When a connector is connected, the module is then electrically contacted at the same time.

Wenn man es vorzieht, den elektrischen Kontakt unabhänig von einem anzuschließenden weiteren Gerät herzustellen, ist nach einer vorteilhaften Ausführung vorgesehen, bei Installationsgeräten mit schraubenlosen Klemmen für anzuschließende Leiter gefederte Kontakte gegen die schraubenlosen Klemmen an einer Stelle ihres Metallgehäuses arbeiten zu lassen. Anstelle des Metallgehäuses der schraubenlosen Klemmen kann man auch elektrisch leitende Metallteile einer die schraubenlosen Klemmen enthaltenden Baugruppe heranziehen oder allgemein elektrisch leitende Metallteile.If you prefer to make the electrical contact independently of another device to be connected, it is provided according to an advantageous embodiment to allow spring-loaded contacts to work against the screwless terminals at one point in their metal housing for installation devices with screwless terminals for conductors to be connected. Instead of the metal housing of the screwless terminals, one can also use electrically conductive metal parts of an assembly containing the screwless terminals or generally electrically conductive metal parts.

Die gefederten Kontakte können als stiftförmige Körper ausgeführt sein, die mittels einer Feder gegen ein Teil des Moduls abgefedert sind.The spring-loaded contacts can be designed as pin-shaped bodies which are spring-loaded against a part of the module.

Zumindest eine schraubenlose Klemme kann in ihrem Klemmengehäuse oder in einem elektrisch leitenden Metallteil einer die schraubenlosen Klemme enthaltenden Baugruppe eine Aussparung aufweisen, in die ein konischer stiftförmiger Körper als gefederter Kontakt aufreitend eingreifen kann. Durch eine derartige Konstruktion werden Oxydhäute jeweils an der lochförmigen Ausparung aufgerissen, so daß sich ein besonders zuverlässiger Kontakt ergibt. Hierbei wird auch ein mechanisch besonders stabiler Kontakt erzielt. Die gefederten Kontakte können auch selbst als Federkörper ausgebildet sein.At least one screwless clamp can have a recess in its clamp housing or in an electrically conductive metal part of an assembly containing the screwless clamp, into which a conical pin-shaped body can engage as a spring-loaded contact. With such a construction oxide skins are torn open at the hole-shaped recess, so that there is a particularly reliable contact. A mechanically particularly stable contact is also achieved here. The spring-loaded contacts can also be designed as spring bodies themselves.

Das elektrotechnische Installationsgerät 1 nach FIG 1 ist als Steckdose in Modulbauweise an einer Unterputzdose 2 eingesetzt veranschaulicht. Durch ein ansteckbares Modul 3 können dem Installationsgerät Zusatzfunktionen mitgegeben werden. Im Modul 3 können elektronische Bauteile, wie Platinen oder Chips, untergebracht werden. Die elektrische Kontaktgabe für das Modul wird jeweils durch gefederte Kontakte 4 erzielt, wenn ein Steckerstift 5 eines Steckers 6 eingeführt wird. Im Ausführungsbeispiel nach FIG 1 ist der gefederte Kontakt 4 als Schraubenfeder 7 aus elektrisch leitendem Material ausgebildet. Hierfür eignet sich beispielsweise Federbronze.The electrical installation device 1 according to FIG. 1 is illustrated as a modular socket on a flush-mounted box 2. Additional functions can be provided to the installation device by a plug-in module 3. Electronic components such as circuit boards or chips can be accommodated in module 3. The electrical contact for the module is achieved in each case by spring-loaded contacts 4 when a plug pin 5 of a plug 6 is inserted. In the exemplary embodiment according to FIG. 1, the spring-loaded contact 4 is designed as a helical spring 7 made of electrically conductive material. Spring bronze, for example, is suitable for this.

Beim Installationsgerät nach FIG 2 werden schraubenlose Klemmen 8 für anzuschließende Leiter für die Kontaktgabe zum Modul 3 genutzt. Im Ausführungsbeispiel nach den FIG 2 und FIG 3 ist der gefederte Kontakt 4 jeweils als Schraubenfeder ausgeführt, die an einer Stelle des Metallgehäuses 9 der schraubenlosen Klemme 8 anliegen und Kontakt geben kann. In FIG 2 ist die Kontaktgabe an einer schraubenlosen Klemme 8 für den Anschluß zu einer Steckbuchse 10 veranschaulicht und in FIG 3 die Kontaktgabe für das Modul an der schraubenlosen Klemme zum Anschließen eines Schutzkontaktbügels 13.In the installation device according to FIG. 2, screwless terminals 8 are used for conductors to be connected for making contact with module 3. In the exemplary embodiment according to FIGS. 2 and 3, the spring-loaded contact 4 is in each case designed as a helical spring, which can bear against the screwless terminal 8 at one point on the metal housing 9 and make contact. FIG. 2 illustrates the contacting on a screwless terminal 8 for connection to a socket 10 and in FIG. 3 the contacting for the module on the screwless terminal for connecting a protective contact bracket 13.

Nach den FIG 4 und 5 sind die gefederten Kontakte jeweils als stiftförmige Körper 11 ausgeführt, die mittels einer Feder 12 gegen ein Teil des Moduls abgefedert sind. In FIG 4 ist die Kontaktgabe für das Modul zur schraubenlosen Anschlußklemme 8 für eine Steckbuchse 10 und in FIG 5 zur schraubenlosen Klemme 8 für einen Schutzkontaktbügel 13 wiedergegeben. Der Aufbau der schraubenlosen Klemmen 8 ist hinlänglich bekannt. Eine Kontaktfeder 14 ist in einem Metallgehäuse 9 angeordnet und kann einen in der Einführungsöffnung 15 einzuführenden Leiter anklemmen. Wenn man einen Lösehebel 16 betätigt, kann ein eingeführter Leiter wieder entfernt werden. Man vergleiche FIG 5.According to FIGS 4 and 5, the spring-loaded contacts are each designed as a pin-shaped body 11 which are spring-loaded against a part of the module by means of a spring 12. FIG. 4 shows the contact for the module for the screwless connection terminal 8 for a socket 10 and in FIG. 5 for the screwless terminal 8 for a protective contact clip 13. The structure of the screwless terminals 8 is well known. A Contact spring 14 is arranged in a metal housing 9 and can clamp a conductor to be inserted in the insertion opening 15. If one actuates a release lever 16, an inserted conductor can be removed again. Compare FIG. 5.

In der Weiterbildung nach FIG 6 weist zumindest eine schraubenlose Klemme 8 in ihrem Klemmengehäuse eine Aussparung 18 auf, in die ein konischer stiftförmiger Körper 17 als gefederter Kontakt 4 aufreitend eingreifen kann. Unter Aufreiten ist hier zu verstehen, daß der konische stiftförmige Körper 17 so weit in die Ausparung 18 eingeführt werden kann, bis er sich in der Aussparung 18 verklemmt. Das Modul 3 kann im übrigen in ansich bekannter Weise durch Rasthalterungen am Installationsgerät gehalten werden.In the development according to FIG. 6, at least one screwless terminal 8 has a recess 18 in its terminal housing, into which a conical pin-shaped body 17 can engage in a spreading manner as a spring-loaded contact 4. Under spreading is to be understood here that the conical pin-shaped body 17 can be inserted into the recess 18 until it jams in the recess 18. The module 3 can also be held in a known manner by means of latching brackets on the installation device.

Die Weiterbildung nach FIG 6 kann auch entsprechend FIG 7 ausgeführt sein, wonach die Kontaktgabe für das Modul 3 durch eine im Profil stiftförmig geformte Feder 19 erfolgt, die sich gegen das Metallgehäuse der schraubenlosen Klemme 8 aufspreizt. Die stiftförmige Feder 19 ist beispielsweise aus einer Blattfeder geformt, die in Rippen 20 des Modulgehäuses einrastbar befestigt ist. In entspannter Form kann die Blattfeder das äußere Profil eines "A" aufweisen.The development according to FIG. 6 can also be carried out according to FIG. 7, according to which the contact for the module 3 is made by a spring 19 shaped in the form of a pin, which spreads out against the metal housing of the screwless terminal 8. The pin-shaped spring 19 is formed, for example, from a leaf spring which is fastened in a snap-in manner in the ribs 20 of the module housing. In a relaxed form, the leaf spring can have the outer profile of an "A".

Nach FIG 8 ist der gefederte Kontakt als im Prinzip stiftförmige Feder 19 in Gestalt eines Hülsensektors ausgeführt, wobei die Feder von oben gesehen halbmondförmig aussehen kann. Federrücken und Federränder können sich in einem Schlitz des Metallgehäuses der schraubenlosen Klemme 8 verspreizen. Die stiftförmige Feder 19 kann in Rippen 20 des Modulgehäuses mit sägezahnförmigem Rand eingreifen und darin gehalten werden.According to FIG. 8, the spring-loaded contact is designed in principle as a pin-shaped spring 19 in the form of a sleeve sector, wherein the spring can look crescent-shaped when viewed from above. Spring backs and spring edges can spread out in a slot in the metal housing of the screwless clamp 8. The pin-shaped spring 19 can engage in ribs 20 of the module housing with a sawtooth-shaped edge and be held therein.

Nach einer Weiterbildung gemäß FIG 9 erfolgt die gefederte Kontaktierung durch einem starren stiftförmigen Körper 22 in einer federnden Stiftaufnahme 23. Diese kann durch einen Kreuzschritt in der Kontaktfeder 14 der schraubenlosen Klemme 8 gebildet sein.According to a development according to FIG. 9, the spring-loaded contact is made by a rigid pin-shaped body 22 in a spring-loaded pin receptacle 23. This can be formed by a cross step in the contact spring 14 of the screwless terminal 8.
