Description

Die Erfindung betrifft ein Steckernetzgerät zur Stromversorgung elektrischer Geräte mit einer Niederspannung, dessen Gehäuse mit einem Netzstecker und einer Leiterplatte versehen ist, welches die elektrischen Bauteile zur Erzeugung einer Niederspannung für die Stromversorgung eines über ein Verbindungskabel anschließbaren elektrischen Gerätes aufweist.The invention relates to a plug-in power supply for power supply of electrical devices with a low voltage, the housing of which is provided with a power plug and a printed circuit board which has the electrical components for generating a low voltage for the power supply of an electrical device which can be connected via a connecting cable.

In verstärktem Umfang finden elektrische Geräte Verwendung, die für eine Stromversorgung mit Niederspannung durch ein besonderes Netzsteckgerät eingerichtet sind. Hierzu gehören auch elektrische Geräte mit Akkumulatoren, die mit Hilfe eines Steckernetzgerätes aufgeladen werden. Die hierfür bekannten Steckernetzgeräte bestehen aus einem Gehäuse, welches die elektrischen bzw. elektronischen Bauteile enthält, die für die Stromversorgung eines über ein Verbindungskabel anschließbaren elektrischen Gerätes erforderlich sind. Außerdem sind am Gehäuse in eine Netzsteckdose einsteckbare Steckerstifte fest angebracht. Da in den verschiedenen Ländern, z. B. Deutschland, Großbritannien, USA, Australien usw. unterschiedliche Netzsteckerstandards in Anwendung sind, müssen solche Steckernetzgeräte in verschiedenen, den Länderstandards entsprechenden Ausführungen hergestellt und angeboten werden. Das hat zur Folge, daß beim Mitführen mobiler elektrischer Geräte, z. B. Laptop-Computer, Videorecorder, Mobiltelefone usw. auf Reisen durch solche Länder ein jeweils geeignetes Steckernetzgerät für die Stromversorgung benötigt wird. Die bekannten Adapter mit einem geeigneten Netzstecker und einer Kupplungsdose für das Gerät sind für Steckernetzgeräte in der Regel ungeeignet, weil der Stecker des Steckernetzgerätes nicht in die Netzdose paßt und das Steckernetzgerät infolge seines Gewichts aus der Kupplungslage leicht herauskippt. Das gilt auch für den aus GB 15 95 897 bekannten, mit festen Steckerstiften versehenen Adapter, der eine Leiterplatte für die elektronischen Bauteile einer einen Stromausfall anzeigenden Warnvorrichtung aufweist und von dem ebenfalls eine der Vielfalt der Länderstandards entsprechende Anzahl Typen benötigt wird.Electrical devices that are set up for a low-voltage power supply by means of a special mains plug device are being used to an increasing extent. This also includes electrical devices with accumulators that are charged using a plug-in power supply. The known plug-in power supply units consist of a housing which contains the electrical or electronic components which are required for the power supply of an electrical device which can be connected via a connecting cable. In addition, plug-in plug pins are firmly attached to the housing in a mains socket. Since in different countries, e.g. B. Germany, Great Britain, USA, Australia, etc. different power plug standards are in use, such power supply units must be manufactured and offered in different versions that meet the country standards. This has the consequence that when carrying mobile electrical devices, for. B. laptop computer, VCR, mobile phones, etc. when traveling through such countries, a suitable plug-in power supply is required for the power supply. The known adapters with a suitable power plug and a coupling socket for the device are generally unsuitable for power packs because the plug of the plug-in power supply unit does not fit into the power socket and the plug-in power supply unit tilts slightly out of the coupling position due to its weight. This also applies to the adapter known from GB 15 95 897, which is provided with fixed plug pins and which has a printed circuit board for the electronic components of a warning device indicating a power failure and of which a number of types corresponding to the diversity of the country standards is also required.

Aus DE 33 00 936 A 1 ist bekannt, mit wiederaufladbaren Batterien ausgerüstete elektrische Geräte, wie Rasierapparate, Kassettengerät, Lampen u. dgl. mit einem Stecker zu versehen, der innerhalb des Gerätegehäuses untergebracht und ausschwenkbar ist, um das Gerät zum Wiederaufladen an eine Netzdose anschließen zu können. Dem Stecker zugeordnete Federkontakte kommen in der eingeschwenkten Lage mit Flächenkontakten in Berührung, an welche die Batteriepole angeschlossen sind. Der Stecker dieser elektrischen Geräte paßt jedoch nur in eine, einem Länderstandard entsprechende Netzsteckdose, so daß die elektrischen Geräte ebenfalls in verschiedenen, den Länderstandards entsprechenden Ausführungen gefertigt und vertrieben werden müssen. Anderseits ist aus US 48 15 983 ein Netzstecker für ein Stromkabel bekannt, bei dem die Steckerstifte an einem auswechselbaren Adapterteil befestigt sind und verschiedene, einem Länderstandard entsprechende Adapterteile zur Verfügung stehen, die wahlweise in das Steckergehäuse und darin angeordnete Anschlußstifte einsteckbar sind. Für Steckernetzgeräte ist eine solche Adapterausbildung aus baulichen Gründen ungeeignet.From DE 33 00 936 A 1 is known, equipped with rechargeable batteries electrical devices such as razors, cassette device, lamps and. The like. To be provided with a plug which is housed within the device housing and can be swung out in order to be able to connect the device to a mains socket for recharging. In the swiveled-in position, the spring contacts assigned to the plug come into contact with surface contacts to which the battery poles are connected. However, the plug of these electrical devices only fits into a power socket that corresponds to a country standard, so that the electrical devices must also be manufactured and sold in different versions that meet the country standards. On the other hand, from US 48 15 983 a power plug for a power cable is known, in which the connector pins are attached to an interchangeable adapter part and various, according to a country standard, adapter parts are available, which can optionally be inserted into the connector housing and connecting pins arranged therein. Such an adapter design is unsuitable for plug-in power supplies for structural reasons.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein dem Oberbegriff des Anspruches 1 entsprechendes Steckernetzgerät derart auszubilden, daß eine einfache Umrüstung auf verschiedene Netzsteckerstandards möglich ist.In contrast, the object of the invention is to design a plug-in power supply unit corresponding to the preamble of claim 1 in such a way that simple conversion to different plug standards is possible.

Diese Aufgabe wird erfindungsgemäß durch einen auswechselbar am Gehäuse befestigbaren Adapterstecker gelöst, dessen Stekkerstifte entsprechend einem beliebigen Länderstandard ausgebildet und jeweils mit einer Kontaktfeder verbunden ist, welche mit entsprechenden, im Steckergehäuse angeordneten Kontaktflächen der Leiterplatte in Kontakt gelangen.This object is achieved according to the invention by an interchangeably attachable adapter plug, the plug pins of which are designed in accordance with any country standard and are each connected to a contact spring which come into contact with corresponding contact surfaces of the printed circuit board arranged in the plug housing.

Diese Ausführung hat den Vorteil, daß das Steckernetzgerät sich in einfacher Weise auf verschiedene Länderstandards umrüsten läßt. Während bei den bekannten Steckernetzgeräten das fest angebrachte Steckerteil sperrig vom Gehäuse absteht, läßt sich das erfindungsgemäß ausgebildete Steckernetzgerät bei abgenommenem Adapterstecker in einer raumsparenden Weise weglegen und auf Reisen mitnehmen.This version has the advantage that the plug-in power supply can be easily converted to different country standards. While in the known plug-in power supplies the fixed plug part protrudes bulky from the housing, the plug-in power supply designed according to the invention can be put away in a space-saving manner when the adapter plug is removed and can be taken along when traveling.

Zweckmäßig weist das Gehäuse an einem Rand eine absatzförmige Vertiefung auf, in welche eine mit den Kontaktflächen versehene Zunge einer elektronischen Leiterplatte ragt, und der Adapterstecker ist mit einem in die Vertiefung passenden Adaptergehäuse versehen, wobei dessen Kontaktfedern im zusammengebauten Zustand gegen die Kontaktflächen der Leiterplatte anliegen. Durch diese Ausbildung wird ein Steckernetzgerät geschaffen, welches die Form einer flachen Kassette aufweist. An den beiden Seiten der Vertiefung ist je eine Nut vorgesehen, in welche seitlich am Adaptergehäuse angebrachte Führungsschienen einschiebbar sind. Hierdurch ist eine schnelle und einfache Anbringung eines Adapterstekkers möglich. Die Halterung in einer Netzsteckdose wird dadurch verbessert, daß die Steckerstifte rechtwinklig zu der von den Führungsschienen gebildeten Einschubfläche angeordnet sind.The housing expediently has a shoulder-shaped depression in one edge, into which a tongue of an electronic circuit board provided with the contact surfaces projects, and the adapter plug is provided with an adapter housing which fits into the recess, the contact springs of which, when assembled, bear against the contact surfaces of the printed circuit board . This design creates a plug-in power supply which has the shape of a flat cassette. A groove is provided on each of the two sides of the depression, into which guide rails attached to the side of the adapter housing can be inserted. This enables a quick and easy attachment of an adapter plug. The holder in a power socket is improved in that the connector pins are arranged at right angles to the insertion surface formed by the guide rails.

Zugeordnet ist weiterhin ein in die Vertiefung des Steckergehäuses passender und mit seitlichen Führungsschienen in die Nuten einschiebbarer Verschlußdeckel. Dieser trägt dafür Sorge, daß das Steckernetzgerät im nicht gebrauchten Zustand verschlossen ist und die Kontaktflächen der Leiterplatte nicht frei liegen.Also assigned is a cover that fits into the recess of the connector housing and can be inserted into the grooves with lateral guide rails. This ensures that the plug-in power supply is not in use State is closed and the contact surfaces of the circuit board are not exposed.

Bei einem Steckernetzgerät, welches infolge seiner Bauteile besonders schwer ist und zweckmäßig auf einer Tragfläche abgestellt wird, sind die im Adaptergehäuse angeordneten Kontaktfedern über ein Netzkabel mit einem Netzstecker verbunden, an dem die Steckerstifte entsprechend einem beliebigen Länderstandard ausgebildet sind. Bei dieser Ausführung wird das Adaptergehäuse mit dem Steckergehäuse verbunden und der am Netzkabel angebrachte Netzstecker in die Netzdose eingesteckt. Um die Halterung der Adapterstecker bzw. des Verschlußdeckels am Gehäuse zu erhöhen, ist das Stekkergehäuse vorzugsweise mit einer Nase versehen, über welche im zusammengebauten Zustand ein Schnappschenkel des Adaptergehäuses bzw. des Verschlußdeckels rastet.In the case of a plug-in power supply, which is particularly heavy due to its components and is expediently placed on a wing, the contact springs arranged in the adapter housing are connected via a power cord to a power plug on which the plug pins are designed in accordance with any country standard. In this version, the adapter housing is connected to the plug housing and the mains plug attached to the mains cable is inserted into the mains socket. In order to increase the mounting of the adapter plug or the closure cover on the housing, the connector housing is preferably provided with a nose via which a snap leg of the adapter housing or the closure cover snaps in the assembled state.

Das in den Fig. 1 bis 3 dargestellte Gehäuse 1 eines Stekkernetzgerätes hat die Form einer flachen Kassette und besteht vorzugsweise aus Kunststoff. Am oberen Rand ist eine Vertiefung 2 vorgesehen, welche durch einen Boden 3, eine Rückwand 4 und zwei Seitenwände 5 begrenzt ist. Innerhalb des Gehäuses ist eine Leiterplatte 6 angeordnet, welche die der Stromversorgung dienenden elektronischen Bauteile aufweist. Sie besitzt eine Zunge 7, welche durch eine Öffnung im Boden 3 in die Vertiefung 2 ragt. Dort ist sie gabelförmig ausgebildet und besitzt an ihren Enden zwei Kontaktflächen 8. In den beiden Seitenwänden 5 ist jeweils eine Nute 9 eingeformt.The housing 1 of a plug-in power supply unit shown in FIGS. 1 to 3 has the shape of a flat cassette and is preferably made of plastic. At the upper edge, a recess 2 is provided, which is delimited by a bottom 3, a rear wall 4 and two side walls 5. A circuit board 6 is arranged within the housing and has the electronic components serving for the power supply. It has a tongue 7 which projects through an opening in the bottom 3 into the recess 2. There it is fork-shaped and has two contact surfaces 8 at its ends. A groove 9 is formed in each of the two side walls 5.

In den Fig. 4 bis 6 ist ein die Vertiefung 2 abdeckender Verschlußdeckel 10 dargestellt. Er besitzt seitliche Führungsschienen 11, mit denen er in die Nuten 9 des Gehäuses 1 einschiebbar ist. Insbesondere Fig. 6 zeigt, daß die Rückseite des Verschlußdeckels 10 mit einer Innenwand und einer Querwand 13 versehen ist. In der Querwand 13 ist ein Schlitz 14 vorgesehen, wie es besonders deutlich der Fig. 5 zu entnehmen ist. Im zusammengebauten Zustand greift ein am unteren Rand des Verschlußdeckels 10 vorgesehener Schnappschenkel über eine am Gehäuse 1 angebrachte Nase, so daß ein sicherer Halt gewährleistet und der Verschlußdeckel nur nach Überwindung einer gewissen Vorspannung abgezogen werden kann.4 to 6, a cover 10 covering the recess 2 is shown. It has lateral guide rails 11 with which it can be inserted into the grooves 9 of the housing 1. In particular, Fig. 6 shows that the back of the cap 10 with an inner wall and a transverse wall 13 is provided. A slot 14 is provided in the transverse wall 13, as can be seen particularly clearly in FIG. 5. In the assembled state, a snap leg provided on the lower edge of the closure cover 10 engages over a nose attached to the housing 1, so that a secure hold is ensured and the closure cover can only be removed after a certain preload has been overcome.

Auch der in den Fig. 8 und 9 dargestellte Adapterstecker 17 ist so ausgebildet, daß er genau in die Vertiefung 2 des Gehäuses 1 paßt. Das Adaptergehäuse 18, ebenfalls aus einem geeigneten Kunststoff gefertigt, ist mit zwei Steckerstiften 19 versehen, die bei dem Ausführungsbeispiel nach Fig. 8 und 9 als sogenannter Euro-Stecker ausgebildet sind. Diese sind jeweils mit einer Kontaktfeder 20 verbunden, die im Inneren des Adaptergehäuses derart angeordnet ist, daß im zusammengesteckten Zustand die Kontaktfedern 20 gegen die Kontaktflächen 8 der Leiterplatte 6 zur Anlage kommen. Ähnlich wie bei dem Verschlußdeckel 10 ist auch das Adaptergehäuse 18 mit einer Innenwand 12, einer Querwand 13 und einem Schlitz 14 versehen. Bauähnlich ist auch die Ausführung eines Schnappschenkels 15, der im zusammengesteckten Zustand über die Nase 16 des Steckergehäuses 1 greift. Die aufgesteckte Lage zeigt Fig. 10 deutlich.The adapter plug 17 shown in FIGS. 8 and 9 is designed so that it fits exactly into the recess 2 of the housing 1. The adapter housing 18, also made of a suitable plastic, is provided with two plug pins 19, which in the embodiment according to FIGS. 8 and 9 are designed as so-called Euro plugs. These are each connected to a contact spring 20 which is arranged in the interior of the adapter housing in such a way that the contact springs 20 come into contact with the contact surfaces 8 of the printed circuit board 6 in the assembled state. Similar to the closure cover 10, the adapter housing 18 is also provided with an inner wall 12, a transverse wall 13 and a slot 14. The construction of a snap leg 15, which engages over the nose 16 of the connector housing 1 in the assembled state, is similar in construction. The attached position is shown clearly in FIG. 10.

Als weiteres Beispiel ist in den Fig. 11 und 12 ein Adapterstecker 17 dargestellt, der für eine Netzsteckdose in Großbritannien geeignet ist. Entsprechend sind die Steckerstifte 21 ausgebildet und ist ein Halterungsstift 22 vorgesehen.As a further example, an adapter plug 17 is shown in FIGS. 11 and 12, which is suitable for a mains socket in Great Britain. The connector pins 21 are formed accordingly and a mounting pin 22 is provided.

Soll das Steckernetzgerät infolge eines höheren Gewichtes nicht unmittelbar an der Netzsteckdose hängen, sondern abgestellt werden, kann die Ausführung nach den Fig. 13 und 14 vorgesehen werden. Bei dieser ist ein Adaptergehäuse 23 über ein Netzkabel 24 mit einem geeigneten Netzstecker 25 verbunden, dessen Steckerstifte mit 26 bezeichnet sind. Das Netzkabel 24 ist mit den Kontaktfedern 20 leitend verbunden, welche ebenfalls derart in den Innenraum des Adaptergehäuses 23 ragen, das im aufgesteckten Zustand eine Anlage gegen die Kontaktflächen der Leiterplatte 6 stattfindet. Zugeordnet sind, wie bei allen Ausführungen, Führungsschienen 11, welche in die Nuten 9 des Steckergehäuses 1 einschiebbar sind.If the plug-in power supply is not to be directly attached to the mains socket due to a higher weight, but is to be switched off, the embodiment according to FIGS. 13 and 14 can be provided. This is an adapter housing 23 via a power cord 24 with a suitable power plug 25 connected, the connector pins are designated 26. The power cord 24 is conductively connected to the contact springs 20, which likewise protrude into the interior of the adapter housing 23 in such a way that, when plugged in, it bears against the contact surfaces of the printed circuit board 6. As with all versions, guide rails 11 are assigned, which can be inserted into the grooves 9 of the plug housing 1.

Selbstverständlich können die Adapterstecker 17 auch mit anderen Netzsteckertypen ausgerüstet werden.Of course, the adapter plug 17 can also be equipped with other types of mains plug.
