Description

Es sind Klemmen zur Verbindung von Leitungen aus verschiedenen Metallen bekannt, die selbst auch aus verschiedenen Metallen bestehen und deren Verbindungsstelle zum Schutz gegen elektrolytische Zersetzung luftdicht abgeschlossen ist. Bei "den bekannten Klemmen dieser Art wird der Abschluß der Verbindungsstelle durch eine Umpressung aus Isoliermasse gebildet.There are known clamps for connecting lines made of different metals, which themselves also consist of different metals and their connection point to protect against electrolytic decomposition is hermetically sealed. In "the known terminals of this type, the termination the connection point formed by a press-fitting of insulating compound.

ίο Nach der Erfindung ist die Schutzmasse in einer Vertiefung der einen Klemmenhälfte enthalten, welche 'die andere in diese eingesetzte Klemmenhälfte umgibt, und durch eine isolierende Schutzplatte abgedeckt. Während eine Umpressung aus Isoliermasse nur ,mittels besonderer Hilfsvorrichtungen hergestellt werden kann und leicht durch die Einwirkung von Wärme und Kälte sowie durch Stöße verletzt wird, kann die Schutzmasse bei der neuen Klemme ohne weiteres von Hand in die Vertiefung eingestrichen und dann mit einer Schutzplatte so abgedeckt werden, daß sie allen Einflüssen entzogen ist.ίο According to the invention, the protective compound is in a recess of one half of the clamp included, which 'surrounds the other clamp half inserted in this, and by a insulating protective plate covered. While an overmolding made of insulating compound only , can be produced by means of special auxiliary devices and easily by the action is injured by heat and cold as well as by shocks, the protective mass of the new terminal can easily be removed from Hand smeared into the recess and then covered with a protective plate become that it is withdrawn from all influences.

Die beiden Klemmenteile sind zweckmäßig durch Verschraubung ineinandergefügt, d. h.The two clamp parts are expediently fitted into one another by screwing, i. H.

es ist an dem einen Teil ein Gewindebolzen und an dem anderen Teil ein Muttergewindethere is a threaded bolt on one part and a nut thread on the other part

• ausgebildet, und an das Muttergewinde schließt sich die mit Isoliermasse auszufüllende Vertiefung an. Die Schutzplatte wird durch eine auf dem Gewindebolzen sitzende Mutter festgesperrt, welche gleichzeitig als Gegenmutter dient, um ein Lösen der Klemmenteile voneinander zu verhindern.• formed, and the nut thread closes with the insulating compound to be filled Deepening. The protective plate is locked by a nut sitting on the threaded bolt, which at the same time as The lock nut is used to prevent the clamping parts from loosening from one another.

In der Zeichnung ist eine Ausführungsform der Klemme dargestellt.In the drawing is an embodiment the terminal shown.

Die Klemme besteht aus zwei Hälften a und h,, die aus verschiedenen, den zu verbindenden Leitungen c und d entsprechenden Metallen bestehen. Der an die durchgehende Eisenleitung c angeschlossene Klemmenteil a besteht also ebenfalls aus Eisen, der mit der Aluminiumleitung d verbundene Teil b aus Aluminium. An dem Teil b ist ein Gewindebolzen e ausgebildet, der in das Muttergewinde f des Teiles α eingreift. An der Stirnseite des Teiles α ist eine Vertiefung g vorgesehen, die mit Isoliermasse ausgefüllt und mittels der Isolierplatte h, der Unterlagscheiibe i und der als Gegenmutter wirkenden Mutter k verschlossen wird. Die Berührungsstelle der verschiedenen Metalle befindet sich also wohlgeschützt innerhalb der Klemme. Elektrolytische Wirkungen sind daher nicht zu befürchten.The clamp consists of two halves a and h, which are made of different metals corresponding to the lines c and d to be connected. The terminal part a connected to the continuous iron line c also consists of iron, the part b connected to the aluminum line d of aluminum. On the part b , a threaded bolt e is formed which engages in the nut thread f of the part α. On the end face of part α a recess g is provided which is filled with insulating compound and closed by means of the insulating plate h, the washer i and the nut k acting as a counter nut. The point of contact between the various metals is therefore well protected within the terminal. Electrolytic effects are therefore not to be feared.
