Description

Die Erfindung betrifft ein Verfahren zur Her-Stellung von in -kleinen, Abständen voneinander angeordneten Verbindungen, wie sie insbesondere- die Wicklungsbedingungen elektrischer Maschinen und Apparate darstellen. Gemäß der Erfindung gelingt es, auf einfachste Weise zwei oder mehrere Hartlöt bzw. Schweißverbindungen auf elektrischem Wege gleichzeitig zu. schaffen; indem zwischen den einzelnen Verbindungsstellen Halbleiter eingelegt und an die äußersten Verbindungsstellen unmittel- oder mittelbar Elektroden angeschlossen werden. Als Halbleiter werden mit besonderem Vorteil Kunstkohlen mit trapezförmigem Querschnitt verwendet,- die zwischen den Verbindungsstellen eingetrieben werden. Durch die Erfindung wird die Herstellungszeit für die Verbindungen wesentlich verkürzt. _ _ In den. Fig. r und 2. der Zeichnung ist die Erfindung bei der Herstellung der Endverbindungen zwischen den Ober- und Unterstäben der Wicklung einer elektrischen Maschine beispielsweise veranschaulicht. Hierbei sind die Oberstäbe r und die Unterstäbe :2 durch die Zwingen 3 miteinander zu verbinden. Zu idiesem Zweck wird zwischen den Zwingen 3 und den Stabenden zunächst Lot eingelegt. Hierauf werden die hier -als Halbleiter verwendeten Lötkohlen 4 mit frapezförmigem Querschnitt von außen her (in Fig. r von oben) zwischen die Verbindungsstellen eingetrieben. Im vorliegenden Fäll werden bei jeder Lätung die sechs Verbindungsstellen. a bis f gleichzeitig fertiggestellt. Dabei. werden die beiden Elektroden 5 und 6 an die außenliegenden Verbindungsstellen der gerade behandelten Gruppe in der Weise von beiden Seiten angedrückt, daß - der Kontaktdruck zwischen den einzelnen zu verbindenden. Teilen genügend groß wird. Aus diesem Grund werden, die Elektroden bzw. Elektrodenhalter über dem Bolzen 7 unter Zwischenschaltung der Feder 8 durch -die Mutter 9 gegeneinandergepreßt. Wie hier gezeigt, werden zweckmäßig auch zwischen den äußersten Verbindungsstellen a und f und den Elektroden Halbleiter eingefügt, damit die Erhitzung ausreichend stark wird. Außerdem kann noch eine Wasserkühlung für die Elektroden bzw. Elektrodenhälter vorgesehen sein. Zu diesem Zweck sind hier Kanäle io in diesen Teilen vorgesehen.The invention relates to a method for producing small, spaced connections, such as those shown in particular - the winding conditions of electrical machines and apparatus. According to the invention, two or more brazed or welded connections can be made at the same time by electrical means in the simplest possible way. create; by inserting semiconductors between the individual connection points and connecting electrodes directly or indirectly to the outermost connection points. Synthetic carbons with a trapezoidal cross-section are used as semiconductors with particular advantage, which are driven in between the connection points. The invention significantly shortens the production time for the connections. _ _ In the. FIGS. R and 2 of the drawing illustrate the invention in the production of the end connections between the upper and lower bars of the winding of an electrical machine, for example. The upper rods r and the lower rods: 2 are to be connected to one another by means of the clamps 3. For this purpose, solder is first inserted between the clamps 3 and the rod ends. The soldering carbons 4 used here as semiconductors with a frapezoidal cross-section are then driven in from the outside (in FIG. R from above) between the connection points. In the present case, the six connection points are used for each lath. a to f completed at the same time. Included. the two electrodes 5 and 6 are pressed against the external connection points of the group just treated in such a way from both sides that - the contact pressure between the individual to be connected. Share becomes big enough. For this reason, the electrodes or electrode holders above the bolt 7 with the interposition of the spring 8 by the nut 9 are pressed against one another. As shown here, semiconductors are expediently inserted between the outermost connection points a and f and the electrodes so that the heating is sufficiently strong. In addition, water cooling can also be provided for the electrodes or electrode holders. For this purpose, channels io are provided in these parts.
