Description
Die vorliegende Erfindung bezieht sich auf Netzanschlußgeräte, insbesondere Radioapparate u. dgl. Bei derartigen Anordnungen sind Vorkehrungen getroffen, um die durch ein äußeres Gehäuse eingeschlossenen inneren Schaltorgane dann spannungslos zu machen, wenn das Gehäuse beispielsweise zwecks Auswechselung einer Verstärkerröhre oder eines anderen Schaltelementes geöffnet wird. Bei den bisher gebräuchlichen Anordnungen war zu diesem Zweck in der Regel neben dem Ein- und Ausschalter des Gerätes ein besonderer Schalter vorgesehen, welcher beim Öffnen des Schutzgehäuses die Stromzuführung unterbrach und somit das Gerät auch bei Betätigung des Bedienungsschalters strom- · los läßt.The present invention relates to network connection devices, particularly radio sets In such arrangements, precautions are taken to prevent the by a then to make the outer housing enclosed inner switching elements de-energized, if the housing, for example, for the purpose of replacing an amplifier tube or a other switching element is opened. In the previously common arrangements was for this purpose, in addition to the on and off switch of the device, there is usually a special one Switch provided, which interrupted the power supply when the protective housing was opened and thus the device as well when the control switch is actuated
Die Erfindung beschreibt eine Verbesserung derartiger Geräte. Erfindungsgemäß ist in dem Gerät nur ein Schalter vorgesehen, dessen Kontakthälften gegeneinander durch den Bedienungsgriff des Schalters und durch ein mit dem Schutzgehäuse in Verbindung stehen-des Sperrorgan bewegt werden. Der durch die Erfindung erreichte VorteiLbesteht darin, daß in dem Gerät lediglich ein Schaltorgan benötigt wird, welches sowohl zur allgemeinen Bedienung des Gerätes als auch für die aus Sicherheitsgründen notwendige Unterbrechung ■30 der Spannungszuführung beim Öffnen des Schutzgehäuses benutzt wird.The invention describes an improvement in such devices. According to the invention, in the device only one switch is provided, the contact halves against each other by the Control handle of the switch and by a with the protective housing in connection Lock member are moved. The advantage achieved by the invention is that only one switching element is required in the device, which is used both for general Operation of the device as well as for the interruption necessary for safety reasons ■ 30 of the voltage supply is used when opening the protective housing.
-Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt. Es bedeuten Z die Zuleitung der Spannung, G das Apparatgehäuse. Es ist ein Schalter vorge-. sehen, der (als doppelpoliger Schalter ausgebildet) aus zwei mit dem Bedienungsschaltergriff B verbundenen Kontakthälften K', K" sowie aus den Kontaktfedern Κχ, Κ»" besteht. Letztere werden durch ein mit dem abnehmbaren, z. B. nach hinten herausziehbaren Schutzgehäuse G verbundenes Sperrorgan, im einfachsten Falle durch einen aus Isolationsmaterial bestehenden Dorn D1 betätigt, welcher nur dann die Kontakte in eine Stellung rückt, in welcher Kontaktschluß mit den anderen Schalterhälften möglich ,ist, wenn sich das Schutzgehäuse in vorschriftsmäßiger Stellung befindet. An Stelle den Dorn D aus Isolationsmaterial zu fertigen, ist es auch möglieh, einen metallenen Sperrhebel zu verwenden, welcher sich .gegen entsprechende Isola- tionsplatten auf den Kontaktfedern legt. · ·-The invention is shown in the drawing in an exemplary embodiment. Z denotes the supply line for the voltage, G the apparatus housing. There is a switch. see, which (designed as a double-pole switch) consists of two contact halves K ', K " connected to the operating switch handle B and the contact springs Κχ, Κ» " . The latter are through a removable, z. B. retractable protective housing G connected locking member, in the simplest case actuated by a mandrel D 1 made of insulation material, which only moves the contacts into a position in which contact closure with the other halves of the switch is possible when the protective housing is in compliance with the regulations Position. Instead of manufacturing the mandrel D from insulation material, it is also possible to use a metal locking lever which rests on the contact springs against corresponding insulation plates. · ·
