Description

Die Erfindung bezieht sich auf eine Berührungsschutzvorrichtung für eine Schutzkontakt-Steckdose unter Einsatz eines Längsschiebers mit direkt angespritzter Rückstellfeder gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung kann beispielsweise bei Unterputz-Steckdosen verwendet werden.The invention relates to a contact protection device for a protective contact socket using a longitudinal slide with directly molded return spring according to the preamble of claim 1. The invention may, for example, in Flush-mounted sockets can be used.

Handelsübliche Steckdosen mit erhöhtem Berührungsschutz entsprechen der E DIN VDE 0624-1, wobei der erhöhte Berührungsschutz durch Verwendung eines Schutzschiebers verwirklicht wird. Dieser Schutzschieber schirmt automatisch die spannungsführenden Kontakte der Steckdose ab, sobald der Stecker aus der Steckdose herausgezogen wird. Der Berührungsschutz ist so beschaffen, daß er nicht in einfacher Art und Weise durch Einführen von anderen Gegenständen als Steckern in die Steckdose umgangen werden kann. Beim Einführen eines geeigneten Steckers wird der Berührungsschutz über eine "schiefe Ebene" geöffnet und die Steckerstifte kommen ordnungsgemäß mit den spannungsführenden Kontakten der Steckdose in Berührung. Beim Herausziehen des Steckers drückt eine Rückstellfeder den Berührungsschutz zurück in seine die Steckeröffnungen verschließende, schützende Position. Commercially available sockets with increased contact protection correspond to E DIN VDE 0624-1, whereby the increased contact protection by using a protective slide is realized. This safety gate automatically shields the live ones Disconnect the contacts from the socket as soon as the plug is removed from the socket is pulled out. The contact protection is such that it is not easier Way by inserting items other than plugs into the socket can be bypassed. When inserting a suitable plug, the contact protection opened over a "sloping plane" and the pins come properly with the live contacts of the socket in touch. When pulling out the plug, a return spring pushes the contact protection back into its protective openings closing the plug openings.

Aus dem Gebrauchsmuster DE 86 33 660 U1 ist eine Steckdose mit einer Kindersicherung bekannt, bei welcher die Steckeröffnungen zur Einführung von Steckerstiften mittels eines Längsschiebers abdeckbar sind und zur Erzeugung der zur Rückführung in die geschlossene Position erforderlichen Federkraft zwei symmetrisch wirksame Blattfedern einstückig am aus Kunststoff hergestellten Längsschieber angeordnet sind. Für eine vollautomatische Montage ist der bekannte Längsschieber nicht geeignet, da die Blattfedern zum Verhaken ineinander während Montage neigen.From the utility model DE 86 33 660 U1 is a socket with a child safety known, in which the plug openings for the introduction of connector pins by means a longitudinal slide can be covered and to generate the return in the closed position required spring force two symmetrically effective leaf springs are integrally arranged on the longitudinal slide made of plastic. For a fully automatic assembly, the known longitudinal slide is not suitable because the Leaf springs tend to snag during assembly.

Aus der DE 2 402 569 A, das als nächstliegender Stand der Technik angesehen wird, ist eine Berührungsschutzvorrichtung für einen Stechdoseneinsatz Sekannt, bei welcher der Längsschieber über separate Rückstellfedern in gesschlossener Position gehalten wird.DE 2 402 569 A, which is the closest prior art is considered a technique, is a contact protection device for a lancet insert seconds, in which the Longitudinal slide is held in a closed position via separate return springs.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bei der vorgeschlagenen Berührungsschutzvorrichtung die Anzahl der verwendeten Teile sowie die Teile- und die Montagekosten sehr gering gehalten werden. Es ist nicht erforderlich, eine separate Rückstellfeder zu fertigen und zu montieren. Der vorgeschlagene Längsschieber ist weitgehend symmetrisch ausgebildet, so daß sich auch hierdurch eine Erleichterung bei der Montage ergibt. Der Längsschieber weist keinerlei hervorstehenden, während der vollautomatischen Montage zum Verhaken neigenden Abschnitte auf.The achievable with the present invention consist in particular that in the proposed contact protection device, the number of parts used as well the parts and assembly costs are kept very low. It is not necessary, to manufacture and assemble a separate return spring. The proposed longitudinal slide is formed largely symmetrical, so that this also a relief during assembly results.
