Damit ergibt sich die Aufgabe, eine derartige Anschluss- und Verbindungsdose bereitzustellen, bei der elektrische Leiter auf einfache Weise, insbesondere auch mit einer einzigen Hand, angeschlossen werden können.This results in the task of providing such a connection and junction box, in which electrical conductors in a simple manner, in particular with a single hand, can be connected.

Ausgehend von der oben beschriebenen elektrischen Anschluss- und Verbindungsdose wird diese Aufgabe durch eine elektrische Anschluss- und Verbindungsdose, mit einem Gehäuse und einer in dem Gehäuse vorgesehenen Klemme zum Anschluss eines elektrischen Leiters, wobei die Klemme geöffnet werden kann, in dem auf eine vorbestimmte Stelle der Klemme eine Kraft ausgeübt wird, wobei in dem Gehäuse eine Vertiefung vorgesehen ist, die derart angeordnet ist, dass bei Öffnung der Klemme mittels eines Schraubendrehers dieser im geöffneten Zustand der Klemme mit seiner Spitze in die Vertiefung gelangt, welche dadurch gekennzeichnet ist, dass die Klemme durch Drehen eines senkrecht zum Boden angesetzten Schraubendrehers geöffnet werden kann.Starting from the electrical connection and junction box described above, this object is achieved by an electrical connection and junction box, with a housing and a terminal provided in the housing for connecting an electrical conductor, wherein the terminal can be opened, in which a predetermined position the terminal is exerted a force, wherein in the housing a recess is provided which is arranged such that when opening the terminal by means of a screwdriver this comes in the open state of the terminal with its tip into the recess, which is characterized in that Clamp can be opened by turning a screwdriver set perpendicular to the floor.

Erfindungsgemäß wird also eine derartige elektrische Anschluss- und Verbindungsdose bereitgestellt, bei der ein zur Öffnung der Klemme verwendeter Schraubendreher aufgrund einer in dem Gehäuse vorgesehenen Vertiefung automatisch in eine Fixierposition gelangt, mit der die Klemme offen gehalten werden kann.According to the invention, therefore, such an electrical connection and junction box is provided in which a screwdriver used for opening the clamp automatically due to a recess provided in the housing enters a fixing position with which the terminal can be kept open.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist dazu vorgesehen, daß die Vertiefung derart ausgebildet und angeordnet ist, daß der Schraubendreher in seiner Stellung fixiert wird, insbesondere nämlich ohne daß er dazu weiter von der Bedienperson gehalten werden muß. Das bedeutet, daß die Bedienperson nach Öffnen der elektrischen Anschluß- und Verbindungsdose zuerst mittels des Schraubendrehers und damit mit nur einer Hand die Klemme öffnen kann, um den Schraubendreher dann loszulassen und den elektrischen Leiter in die geöffnete Klemme einzuführen. Dann kann die Bedienperson wieder umgreifen und den Schraubendreher entfernen, so daß der elektrische Leiter in der Klemme fixiert wird. Damit wird für die gesamte Installationstätigkeit lediglich eine einzige Hand benötigt.According to a preferred embodiment of the invention, it is provided that the recess is designed and arranged such that the screwdriver is fixed in its position, in particular namely without him to be further held by the operator. This means that the operator after opening the electrical connection and junction box first by means of the screwdriver and thus with only one hand can open the terminal to then let go of the screwdriver and insert the electrical conductor in the open terminal. Then the operator can again engage around and remove the screwdriver, so that the electrical conductor is fixed in the terminal. This means that only a single hand is required for the entire installation activity.

Grundsätzlich kann die Klemme auf unterschiedliche Weisen mittels des Schraubendrehers geöffnet werden. Gemäß einer bevorzugten Weiterbildung der Erfindung ist jedoch vorgesehen, daß die Klemme derart ausgebildet und angeordnet ist, daß diese durch Drehen eines senkrecht zum Boden angesetzten Schraubendrehers geöffnet werden kann. Gemäß einer bevorzugten Weiterbildung der Erfindung ist dabei ferner vorgesehen, daß die Vertiefung im Boden des Gehäuses angeordnet ist.In principle, the clamp can be opened in different ways by means of the screwdriver. According to a preferred embodiment of the invention, however, it is provided that the terminal is designed and arranged such that it can be opened by turning a perpendicular to the floor attached screwdriver. According to a preferred embodiment of the invention, it is further provided that the recess is arranged in the bottom of the housing.

Grundsätzlich ist es möglich, den Schraubendreher zum Öffnen der Klemme frei anzusetzen. Gemäß einer bevorzugten Weiterbildung der Erfindung ist jedoch für die Drehung des Schraubendrehers ein Widerlager vorgesehen. An diesem kann der Schraubendreher dann angesetzt werden, was einerseits die Kraftübertragung zur Öffnung der Klemme und andererseits einen präzisen Ansatz des Schraubendrehers in der richtigen Position wesentlich erleichtert.In principle, it is possible to use the screwdriver to open the clamp freely. According to a preferred embodiment of the invention, however, an abutment is provided for the rotation of the screwdriver. At this, the screwdriver can then be attached, which on the one hand facilitates the transmission of power to the opening of the terminal and on the other hand a precise approach of the screwdriver in the correct position.

Darüber hinaus kann gemäß einer bevorzugten Weiterbildung der Erfindung vorgesehen sein, daß das Widerlager zusammen mit der geschlossenen Klemme eine Einsatzöffnung für den Schraubendreher definiert. Damit wird eindeutig die Position vorgegeben, mit der der Schraubendreher angesetzt werden soll, um die Klemme zu öffnen und schließlich in geöffnetem Zustand der Klemme mit seiner Spitze in die Vertiefung zu gelangen, um den geöffneten Zustand der Klemme zu halten.In addition, according to a preferred embodiment of the invention may be provided that the abutment defines an insertion opening for the screwdriver together with the closed terminal. This clearly specifies the position with which the screwdriver is to be used to open the clamp and finally in the open state To reach the clamp with its tip in the recess to hold the open state of the terminal.

Grundsätzlich ist eine Vielzahl von Arten von Klemmen verwendbar. Gemäß einer bevorzugten Weiterbildung ist jedoch als Klemme eine Zugfederklemme vorgesehen. Dabei kann gemäß einer bevorzugten Weiterbildung der Erfindung ferner vorgesehen sein, daß die Zugfederklemme parallel zum Boden des Gehäuses angeordnet ist, Bei Ansatz des Schraubendrehers mit seiner Spitze parallel zur Einführungsöffnung des elektrischen Leiters in die Zugfederklemme kann damit durch Drehen des Schraubendrehers um ca. 45° eine vollständige Öffnung der Zugfederklemme erzielt werden, wie weiter unten im Detail erläutert.In principle, a variety of types of clamps are usable. According to a preferred embodiment, however, a tension spring clamp is provided as a terminal. In this case, according to a preferred embodiment of the invention may further be provided that the tension spring clamp is arranged parallel to the bottom of the housing, at approach of the screwdriver with its tip parallel to the insertion opening of the electrical conductor in the tension spring clamp can thus by turning the screwdriver by about 45 ° a complete opening of the tension spring clamp can be achieved, as explained in detail below.

Im einzelnen gibt es nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße elektrische Anschluß- und Verbindungsdose auszugestalten und weiterzubilden. Dazu wird auf die dem Patentanspruch 1 nachgeordneten Patentansprüche sowie die nachfolgende detaillierte Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung unter Bezugnahme auf die Zeichnung verwiesen. In der Zeichnung zeigt

In particular, there are a variety of ways to design and further develop the electrical connection and junction box according to the invention. For this purpose, reference is made to the claims subordinate to claim 1 and the following detailed description of a preferred embodiment of the invention with reference to the drawings. In the drawing shows

an electrical connection and junction box according to a preferred embodiment of the invention in a perspective view prior to insertion of an electrical conductor,
Fig. 2
the electrical connection and connection box Fig. 1 partially in plan view and
Fig. 3
the electrical junction box according to the preferred embodiment of the invention in perspective view with inserted electrical conductor.

Aus Fig. 1 ist eine elektrische Anschluß- und Verbindungsdose gemäß einem bevorzugten Ausführungsbeispiel der Erfindung ersichtlich, die ein Gehäuse 1 und zwei in dem Gehäuse 1 vorgesehene Klemmen 2 zum Anschluß eines elektrischen Leiters 3 aufweist. Die Klemmen 2 weisen die Form von Zugfederklemmen auf und sind parallel zum Boden 4 des Gehäuses 1 angeordnet.Out Fig. 1 an electrical connection and junction box according to a preferred embodiment of the invention can be seen, which has a housing 1 and two provided in the housing 1 terminals 2 for connecting an electrical conductor 3. The clamps 2 have the form of tension spring clamps and are arranged parallel to the bottom 4 of the housing 1.

Wie aus der Draufsicht aus Fig. 2 ersichtlich, ist vorgesehen, den elektrischen Leiter 3 parallel zum Boden 4 des Gehäuses 1 einzuführen, wozu die Klemme 2 geöffnet werden muß. Eine Öffnung der Klemme 2 wird nun dadurch erzielt, daß ein in Fig. 1 und Fig. 3 gezeigter Schraubendreher 5 zwischen der Klemme 2 und einem auf dem Boden 4 des Gehäuses 1 vorgesehenen Widerlager 6 angesetzt wird. Damit gibt sich eine definierte Ausrichtung der Spitze des Schraubendrehers 5, und zwar in Einführungsrichtung des elektrischen Leiters 3.As seen from the top view Fig. 2 can be seen, it is provided to introduce the electrical conductor 3 parallel to the bottom 4 of the housing 1, to which the terminal 2 must be opened. An opening of the terminal 2 is now achieved by a in Fig. 1 and Fig. 3 shown screwdriver 5 between the terminal 2 and provided on the bottom 4 of the housing 1 abutment 6 is recognized. This results in a defined orientation of the tip of the screwdriver 5, in the direction of insertion of the electrical conductor. 3

Wird der Schraubendreher 5 nun von einer Bedienperson im Uhrzeigersinn um ca. 45° gedreht, so wird die Klemme 2 geöffnet, wobei bei Erreichen der geöffneten Stellung der Klemme 2 die Spitze des Schraubendrehers 5 in eine Vertiefung 7 im Boden 4 des Gehäuses 1 gelangt, so daß der Schraubendreher 5 in dieser Position fixiert wird und von der Bedienperson losgelassen werden kann.If the screwdriver 5 is now rotated by an operator in the clockwise direction by about 45 °, the terminal 2 is opened, upon reaching the open position of the terminal 2, the tip of the screwdriver 5 enters a recess 7 in the bottom 4 of the housing 1, so that the screwdriver 5 is fixed in this position and can be released by the operator.

Damit verbleibt die Klemme 2 in ihrem geöffneten Zustand, so daß die Bedienperson z. B. mit der Hand, mit der sie zuvor den Schraubendreher 5 bedient hat, nunmehr den elektrischen Leiter 3 in die geöffnete Klemme 2 einführen kann. Dann kann die Bedienperson schließlich den Schraubendreher 5 wieder entfernen, so daß die Klemme 2 in ihren geschlossenen Zustand zurückkehrt und den elektrischen Leiter 3 elektrisch leitend fixiert.This leaves the terminal 2 in its open state, so that the operator z. B. with the hand, with which she has previously operated the screwdriver 5, now the electrical conductor 3 can introduce into the open terminal 2. Then, the operator can finally remove the screwdriver 5 again, so that the terminal 2 returns to its closed state and fixes the electrical conductor 3 electrically conductive.

Insgesamt wird damit eine derartige elektrische Anschluß- und Verbindungsdose bereitgestellt, bei der elektrische Leiter 3 auf einfachste Weise und insbesondere auch nur mit einer einzigen einer Bedienperson zur Verfügung stehenden Hand angeschlossen werden können. Auf diese Weise eignet sich die elektrische Anschluß- und Verbindungsdose insbesondere auch als Solardose zum Anschluß von auf z. B. einem Hausdach vorgesehenen und damit schwer zugänglichen Solarzellen.Overall, so that such electrical connection and junction box is provided in the electrical conductor 3 can be connected in the simplest way, and in particular only with a single hand available to an operator. In this way, the electrical connection and junction box is particularly suitable as a solar outlet for connection to z. B. a rooftop and thus difficult to access solar cells.
