Description

Die Erfindung betrifft eine elektrische Schutzkontakt­steckdose nach dem Oberbegriff des Anspruchs 1.The invention relates to an electrical protective contact socket according to the preamble of claim 1.

Aus der DE-PS 16 90 436 ist eine elektrische Schutzkon­taktsteckdose bekannt, welche für den Anschluß eines Phasenleiters, eines Null-Leiters sowie eines Schutz­leiters geeignete schraubenlose Leiteranschlußklemmen aufweist. Hierbei sind die Polleiteranschlußklemmen spitzwinklig zur Schutzleiteranschlußklemme ausge­richtet, wobei sämtliche Leiteranschlußklemmen von einer Anschlußseite her zugänglich sind. Auch ist ein gemein­sames Klemmfederlöseorgan vorgesehen, welches die Klemmfederaufnahmen der Leiteranschlußklemmen abdeckt sowie mittels am Klemmfederlöseorgan angebrachter Klemmfederdruckknöpfe den elektrischen Anschluß sowie die elektrische Trennung der Stromleiter erleichtert.From DE-PS 16 90 436 an electrical protective contact socket is known which has suitable screwless conductor terminals for connecting a phase conductor, a neutral conductor and a protective conductor. Here, the pole conductor terminals are aligned at an acute angle to the protective conductor terminal, with all conductor terminals being accessible from one connection side. A common clamping spring release element is also provided, which covers the clamping spring receptacles of the conductor connection terminals and facilitates the electrical connection and the electrical separation of the current conductors by means of clamping spring push buttons attached to the clamping spring release element.

Die im genannten Stand der Technik offenbarte Leiteran­schlußklemme ist jedoch für eine automatisierte Ferti­gung und Montage noch nicht optimal geeignet. So ist beispielsweise die Klemmfeder als separates Teil in einer Formnische des Sockels untergebracht. Auch die Steckkontaktbuchse ist noch als separates, von der Leiteranschlußklemme getrenntes Teil gefertigt. Ferner ist nachteilig, daß die in einer Formnische des Sockels aufgenommene Klemmfeder den anzuschließenden Leiter nur an einer Stelle kontaktiert, wodurch die Kontaktgabe verschlechtert und der Übergangswiderstand erhöht ist. Auch ist der Durchbruch in den Stromschienen, in welchen der Klemmfederdruckknopf hineingreift, nicht zentral ausgebildet. Dies erschwert eine wahlweise erwünschte Umrüstbarkeit auf Schraubklemmen. Ferner führen die mittels elastischer Stege am Sockeloberteil angeformten Klemmfederlösedruckknöpfe eine lineare Bewegung durch, wodurch deren Stege gestaucht werden, was den Material­verschleiß erhöht.However, the conductor connecting terminal disclosed in the prior art mentioned is not yet optimally suitable for automated production and assembly. For example, the clamping spring is accommodated as a separate part in a form niche of the base. The plug contact socket is also manufactured as a separate part separate from the conductor connection terminal. A further disadvantage is that the clamping spring accommodated in a form niche of the base contacts the conductor to be connected only at one point, as a result of which the contacting deteriorates and the contact resistance is increased. The opening in the busbars, in which the clamping spring push-button engages, is also not formed centrally. This makes it difficult to convert to screw terminals as desired. Furthermore, the clamping spring release pushbuttons formed on the upper part of the base by means of elastic webs carry out a linear movement, as a result of which their webs are compressed, which increases material wear.

Aufgabe vorliegender Erfindung ist es, unter Vermeidung obiger Nachteile die Leiteranschlußklemmen einer Schutz­kontaktsteckdose der im Oberbegriff des Anspruchs 1 genannten Art so auszubilden, daß eine automatische Fertigung sowie eine Umrüstbarkeit von schraubenlosem Klemmanschluß auf Schraubklemmanschluß in einfacher Weise ermöglicht ist, wobei unter Einhaltung ein­schlägiger Normen alle Leiteranschlußklemmen bei gleich­zeitig guter Kontaktgabe elektrisch sicher und bediener­freundlich von einer Leiteranschlußseite her zugänglich sein sollen.The object of the present invention is, while avoiding the above disadvantages, to design the conductor connection terminals of a protective contact socket of the type mentioned in the preamble of claim 1 in such a way that automatic manufacture and convertibility from screwless terminal connection to screw terminal connection is made possible in a simple manner, all conductor connection terminals being observed in compliance with relevant standards should be electrically safe and user-friendly from a conductor connection side with good contact at the same time.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeich­neten Merkmale gelöst. Zweckmäßige Ausgestaltungen und Weiterbildungen des Erfindungsgegenstandes sind in den Unteransprüchen näher gekennzeichnet.This object is achieved by the features characterized in claim 1. Expedient refinements and developments of the subject matter of the invention are characterized in more detail in the subclaims.

Dadurch, daß als Klemmfederaufnahme ein eigenes Klemm­federgehäuse ausgebildet ist, welches mit der Polsteck­kontaktbuchse materialeinheitlich verbunden ist, ist für die Polleiter eine Polleiteranschlußklemme geschaffen, welche als einstückiges Stanz- und Biegeteil fertigbar und nach Aufnahme der Klemmfeder in den Steckdosensockel eingesetzt und verrastet werden kann. In gleicher Weise ist eine Schutzleiteranschlußklemme geschaffen, welche nach Aufnahme der Klemmfeder zusammen mit dem Schutzkon­takterdungsbügel zu einem einstückigen Montageteil verbunden ist.Characterized in that a separate spring clip housing is formed as a clamping spring receptacle, which is connected to the same material with the pole plug contact socket, a pole conductor connecting terminal is created for the pole conductor, which can be manufactured as a one-piece stamped and bent part and can be inserted and locked into the socket base after the clamping spring has been recorded. In the same way, a protective conductor connecting terminal is created, which, after receiving the clamping spring, is connected together with the protective contact earthing clip to form an integral assembly part.

Besonders vorteilhaft ist, daß die ebenfalls einstückige Sockelabdeckung sämtliche elektrischen Teile abdeckt und mittels angeformter Klemmfederlösetasten sich gleichzei­tig ein einfaches Lösen der jeweiligen Klemmverbindung bewerkstelligen läßt.It is particularly advantageous that the base cover, which is also in one piece, covers all electrical parts and, at the same time, simple release of the respective clamp connection can be achieved by means of molded spring release buttons.

Hierbei ist vorteilhaft, daß der vom jeweiligen Druck­nocken der Klemmfederlösetasten zu durchgreifende Durchbruch im Klemmfedergehäuse zentral angebracht ist, weil dadurch eine leichte Umrüstbarkeit auf einen Schraubklemmanschluß erreichbar, d.h. beispielsweise eine Lift-Schraubklemme einsetzbar ist. In die Klemm­federgehäuse eingeformte Sicken ergeben im Zusammen­wirken mit den Klemmkanten der Klemmfeder einen sicheren Sitz der anzuschließenden Stromleiter. Durch die vor­teilhafte Ausbildung der Klemmfeder mit jeweils zwei S-förmigen Stützschenkeln, welche die Stromleiter noch zusätzlich klemmen, ist eine Verringerung des Übergangs­widerstands sowie eine bessere Kontaktgabe erreicht. Die Klemmfeder selbst kann in einfacher Weise mittels einer Rastverbindung im Klemmfedergehäuse verrastet werden.It is advantageous here that the opening to be penetrated by the respective pressure cams of the clamping spring release buttons is mounted centrally in the clamping spring housing, because this makes it easy to convert to a screw terminal connection, ie, for example, a lift screw terminal can be used. Beading molded into the clamping spring housing, in cooperation with the clamping edges of the clamping spring, results in a secure fit of the current conductors to be connected. Due to the advantageous design of the clamping spring, each with two S-shaped support legs, which the current conductor still additionally clamp, a reduction in contact resistance and better contacting is achieved. The clamping spring itself can be locked in a simple manner by means of a locking connection in the clamping spring housing.
