Description
'Beschreibung''Description'
Die als Gebrauchsmusteranmeldung aufgeführten Gegenstände sind Dolü-Reihenklemmen und ein vierpoliger Klemmstein die in der Elektroinstallation (z. B. in Abzweigdosen) zum Verklemmen von Drähten eine große Anwendung finden. Bei der Vielfalt der Klemmverbindungen in der Starkstromtechnik ist es bei faßt allen Verbindungsklemmen möglich eine bessere, sichere und schnellere Montage der Verdrahtung von Stromkreisen durchzuführen. Bei der Herstellung der von mir geänderten Verbindungsklemmen ist es nur erforderlich, beide Seiten der Bohrung des Klemmloches die eckigen Kanten konisch aufzuweiten. Dann ist das Verklemmen von Drähten, im konisch aufgeweiteten Klemmloch, zuverlässiger mit meist ohne Fehler vorzunehmen. Bei dem von mir geänderten Verbindungsklemmen ist das nichterfassen eines Drahtes im Klemmloch dann kaum noch möglich. Wenn ein Draht bei der bislang verwendeten Klemmtechnik nicht richtig erfaßt wird, kann es vorkommen, daß durch zu hohe Übergangswiderstände große Wärme und Brandgefahr entstehen können. Die dargestellten Fig. 1-6 in der Zeichnung ist eine einpolige Dolü-Reihenklemme 5 &khgr; 1,5 [Tj · Die Fig. 7+8 ist ein vierpoliger Klemmstein 5 &khgr; 1,5 &Ggr;&Pgr; für EIt.-Abzweigdosen.The items listed as a utility model application are Dolü series terminals and a four-pole terminal block which are widely used in electrical installations (e.g. in junction boxes) for clamping wires. With the variety of clamp connections in high voltage technology, it is possible to assemble the wiring of circuits better, more safely and more quickly with almost all connecting terminals. When producing the connecting terminals I have modified, it is only necessary to widen the square edges on both sides of the drill hole in a conical manner. Then the clamping of wires in the conically widened terminal hole is more reliable and usually without errors. With the connecting terminals I have modified, it is then almost impossible for a wire to not be gripped in the terminal hole. If a wire is not gripped correctly with the clamping technology used up to now, it can happen that excessive contact resistance can cause a lot of heat and a fire hazard. The figures 1-6 shown in the drawing are a single-pole Dolü series terminal 5 x 25 mm. 1.5 [Tj · Fig. 7+8 is a four-pole terminal block 5 x 1.5 Γ&Pgr; for EIt. junction boxes.

Darstellung eines vierpoligen Klemmsteines für EIt-Abzweigdosen. Der Klemmstein ist im Klemmblock genauso aufgebaut wie die in der Zeichnung angegebene Fig. 5 der Dolü-Reihenklemme. Der Unterschied besteht nur darin, daß die 4 Klemmblöcke in einem gemeinsamen Isoliersteg fest miteinander verbunden sind.Illustration of a four-pole terminal block for EIt junction boxes. The terminal block is constructed in the terminal block in the same way as the Dolü series terminal shown in the drawing Fig. 5. The only difference is that the 4 terminal blocks are firmly connected to one another in a common insulating bar.

Die in der Zeichnung dargestellte Fig. 8 ist der gleiche Klemmblock wie die Fig. 5 Schnitt A-A. nur das bei der Fig. 8 der Isoliersteg mit der Bezeichnung 1 zu sehen ist. Bei der beschriebenen technischen Änderung der Dolü-Reihenklemme und dem vierpoligen Klemmstein ist nur eine konische Aufweitung des Klemmloches vorzunehmen. Diese technisch geänderten Merkmale der Verbindungsklemmen sollen als Gebrauchsmusteranmeldung in der Rolle als Gebrauchsmuster eingetragen werden.Fig. 8 shown in the drawing is the same terminal block as Fig. 5, section A-A. The only difference is that in Fig. 8 the insulating bar with the designation 1 can be seen. With the technical modification described to the Dolü series terminal block and the four-pole terminal block, only a conical widening of the terminal hole is required. These technically modified features of the connecting terminals are to be registered as a utility model application in the utility model register.

übersichtlich dargestellt.The Dolü series terminals 5x1.5 I]J and the four-pole terminal block 5 x 1/5 Γ&Pgr; for electrical junction boxes, which are widely used in electrical installations, are to be conically widened at the wire entry terminal hole. This will make clamping wires easier, safer and more numerous than the clamping technology used so far. The modified technical features of the Dolü series terminal and the
four-pole terminal block are shown in the drawing by the
Fig. 1-8 with the label 3 for better understanding
clearly presented.
