Description
Bei den gebräuchlichen Kabelverbindungen, insbesondere für Schweißzangen, ist das Kabel starr mit der Schweißzange verbunden. Dies hat den Nachteil, daß nicht nur allgemein das Arbeiten behindert ist, sondern auch durch die häufig unvermeidl,ichen Verdrehungen der Zange gegenüber dem Kabel in ,diesem Verschlingungen, Knicke sowie Brüche und, darüber hinaus Isolationsschäden entstehen, die einen vorzeitigen Verschleiß des Kabels zur Folge haben. Außerdem ist wegen der häufigen Reparaturen kein ununterbrochener Arbeitsablauf mögl'ic'h.With the common cable connections, especially for welding guns, the cable is rigidly connected to the welding gun. This has the disadvantage that not work is only hindered in general, but also by the often unavoidable Twists of the pliers in relation to the cable, this tangles, kinks as well Breaks and, in addition, insulation damage, which result in premature wear of the cable. Also, because of the frequent repairs, it is not an uninterrupted one Workflow possible.
Die Erfindung vermeidet diesen Übelstand: durch einen drehbaren Kabelanschluß, bei welchem erfindüngsgemäß die Verbindung zwischen dem Kabel und den stromabgebenden bzw. weiterleitenden Teilen über zwischengeschaltete Rollkörper (z. B. kugelige, zylindr4ische, ball:i,ge oder lcegelförmige Körper) erfolgt, die unter der Wirkung von Kräften, z. B. Federkräften, den Kontakt herstellen.The invention avoids this drawback: by means of a rotatable cable connection, in which according to the invention the connection between the cable and the power supplying or transferring parts via intermediate rolling elements (e.g. spherical, cylindrical, ball: i, ge or lcegel-shaped body) takes place under the action of forces, e.g. B. spring forces to make contact.
In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine Schweißzange mit drehbarem Kabelansatz dargestellt.In the drawing, a welding gun is an embodiment of the invention shown with rotatable cable attachment.
Das bisher mit der Elektrodenzange starr verbundene Kabef 9 endet erfindungsgemäß in einem Kabelschaft mit Telleransatz 3. Dieser Kabelschaft ist über das Kugellager q. gegenüber einem Führungsring 5 drehbar gelagert. Dem Telleransatz 3 gegenüber befindet sieh. ein zweiter Teller mit dem Zangenansatz i, zwischen denen Kugeln 2 gelagert sind, die als Strotübrücke dienen. Der Teller 3 mit dem Kabelschaft wird über den. Führungsring 5 und einen isolierenden Zwischenring 6 durch eine Feder 7 unter Druck gehalten. Die Feder 7 ist dabei im eigentlichen Handgriff 8 aus zweckmäßig unzerbrec'hl'icher Isoliermasse gelagert und stützt sich an dessen rückwärtigem Ende ab.The cable 9, which was previously rigidly connected to the electrode clamp, ends according to the invention in a cable shaft with a plate extension 3. This cable shaft is about the ball bearing q. mounted rotatably with respect to a guide ring 5. The plate approach 3 opposite is see. a second plate with the pincer attachment i, between them Balls 2 are stored, which serve as a Strotübrücke. The plate 3 with the cable shaft is about the. Guide ring 5 and an insulating intermediate ring 6 by a spring 7 held under pressure. The spring 7 is useful in the actual handle 8 from unbreakable insulating compound is stored and is supported on its rear End off.
Die entsprechend denn Radius der Kugeln 2 ausgedrehten Laufflächen an den Tellern z und 3 gewährleisten einen einwandfreien Stromübergang mit ausreichenden Kontaktflächen, die durch den dauernden Druck der Feder 7 mit S'icher'heit aufrechterhalten bleiben, so daß selbst bei niedrigster Spannung ein einwandfreier Stromfluß vorhanden ist.The running surfaces turned out according to the radius of the balls 2 on the plates z and 3 ensure a perfect current transfer with sufficient Contact surfaces which are maintained with S'icher'heit by the constant pressure of the spring 7 remain, so that there is a perfect current flow even at the lowest voltage is.
Die eigentlichen Stromübergangsstellen 3,2 und i sind von einer besonderen Hülse io umschlossen und gegenüber dem eigentlichen Handgriff 8 über den zwischengeschalteten. Isoherrin;g 6 isoliert, so daß nicht nur die Feder 7 stromlos ist, sondern der Stromübergang bzw. die Stromabnahme überhaupt im vorgebauten Kopfstück erfolgt. Dadurch wird erreicht, daß auch bei Dauersdhweißung mit starken Elektroden keine Überhitzung des Handgriffes 8 eintritt.The actual current transfer points 3, 2 and i are enclosed by a special sleeve io and opposite the actual handle 8 via the interposed one. Isoherrin; g 6 insulated, so that not only is the spring 7 de-energized, but the current transfer or the current consumption takes place in the front end piece. This ensures that no overheating of the handle 8 occurs even with permanent welding with strong electrodes.
Der drehbare Kabelanschluß nach der Erfindung stellt einen erheblichen technischen Fortschritt dar, weil Verdrehungen des Kabels verhindert sind bei gleichzeitig vorteilhafter Gestaltung der Stromü@bergangsver'hältnisse. Derartige pKabelverbindungen lassen sich mit Vorteil überall da anwenden, wo es darauf ankommt, ein Kabel drehbar an eine Stromentnahme- oder Stromübergangsstelle anzuschließen.The rotatable cable connection according to the invention represents a considerable technical progress because twisting of the cable is prevented at the same time advantageous design of the flow transition conditions. Such cable connections can be used with advantage wherever it matters, a cable can be rotated to be connected to a current withdrawal or current transfer point.
