Description
Die Erfindung bezieht sich auf ein Rundfunkgerät, bei dem für die verschiedenen Wellenbereiche eine Reihe von Wellenbereichspulen zur Anpassung der Antenne vorgesehen sind.The invention relates to a radio device in which for the various Waveband a number of waveband coils are provided for adjusting the antenna are.
Eis sind Rundfunkgeräte bekannt, bei denen die Umschaltung dieser Wellenbereichspulen durch einen Schalter geschieht. Die Erfindung bezieht sich aber auf Geräte, bei denen mit diesen Spulen verbundene Buchsen vorgesehen sind, über welche der Anschluß der Antenne an die Wellenhereichspulen mittels eines "Steckers erfolgt. Bei derartigen Geräten werden erfindungsgemäß durch denIce radios are known to have the switching of these waveband coils is done by a switch. The invention but refers to devices in which sockets connected to these coils are provided are, via which the connection of the antenna to the waveband coils by means of a "plug takes place. In such devices according to the invention by the
Vorgang des Anschiießens der Antenne an die gewünschte Wellenbereichspule gleichzeitig die für den Empfang dieses Bereiches erforderlichen zusätzlichen Schaltmaßnahmen vorgenommen. Es geschieht dies so, daß eine über den den Wellenbereichspulen zugeordneten Buchsen, wie an sich bekannt, verschiebbar angeordnete und mit Durchstecköffnungen versehene Leiste mit einer oder mehreren Schaltvorrichtungen derart gekuppelt ist, daß. je nach der Stellung der Leiste eine oder mehrere für die Inbetriebsetzung des Rundfunkgerätes auf einem der Wellenbereiche erforderliche Schaltmaßnahmen durchgeführt werden. Hierbei sind die Durchstecköffnungen auf der Leiste so verteilt, und diese ist selbst so angeordnet, daß vor Einstecken eines Anschlußsteckers jeweils immer nur die Buchsengruppe desjenigen Wellenbereiches offenliegt, dem die Einstellung der Schaltvorrichtung bei der betreffenden Leistenstellung entspricht. Diese Einrichtung hat den Vorteil, daß lediglich durch Einsetzen des Steckerstiftes das Gerät für den gewünschten Wellenbereich empfangsbereit gemacht ist.The process of connecting the antenna to the desired waveband coil at the same time the additional switching measures required for the reception of this area performed. It does this in such a way that one is assigned to the waveband coils Sockets, as known per se, are slidably arranged and have through openings provided bar is coupled with one or more switching devices such that. depending on the position of the Bar one or more for putting the radio into operation on one of the Required switching measures are carried out. Here are the Through openings distributed on the bar, and this is itself arranged so that before inserting a connector, always only the socket group of that person Wave range is open to which the setting of the switching device in the relevant Groin position corresponds. This device has the advantage that the device is simply inserted by inserting the plug pin is ready to receive for the desired waveband.
Sofern für einen Wellenbereich die.Durchstecköffnungen derAbdeckleiste so groß sind, daß die betreffenden Anschlußbuchsen auch in den ihnen nicht zugeordneten Stellungen der Leiste offenliegen, muß an der Leiste eine Feder angebracht sein, unter deren Einwirkung die Leiste immer, auch, wenn ein Anschlußstecker nicht eingesteckt ist, in diejenige Stellung gezogen wird, die den dauernd offenliegenden Anschlußbuchsen zugeordnet ist.Provided that the through-holes are used for a wave range the cover strip are so large that the relevant connection sockets are also in the positions not assigned to them the bar are exposed, a spring must be attached to the bar under its action the bar always, even if a connector is not plugged in, into that one Position is pulled, which is assigned to the permanently exposed connection sockets.
Die Beeinflussung der zu betätigenden Schalteinrichtungen kann entweder unmittelbar durch die Leiste selbst oder über weitere Übertragungsglieder erfolgen. Im erstgenannten Falle kann die beeinflussende Leiste je einen Kontakt der zu beeinflussenden Schalter tragen, dessen anderer Kontakt an einem Gehäuse- oder Abschirmteil unmittelbar angeordnet ist.The switching devices to be operated can be influenced either directly take place through the bar itself or via further transmission links. In the former In the event, the influencing bar can each have a contact with the one to be influenced Wear switch, the other contact on a housing or shielding part directly is arranged.
Zweckmäßigerweise ist die Bewegung der Leiste durch Anschläge begrenzt.The movement of the bar is expediently limited by stops.
