Description

Beschreibungdescription
Elektrisch leitende Verbindung zwischen einer Endelektrode und einem AnschlußdrahtElectrically conductive connection between an end electrode and a connecting wire
Die Erfindung liegt auf dem Gebiet der elektrische leitenden Verbindungen und ist bei der konstruktiven Ausgestaltung einer Schweißverbindung zwischen einer Endelektrode einer gas- gefüllten Entladungsstrecke - wie einem Überspannungsabieiter oder einer Schaltfunkenstrecke - und einem Anschlußdraht anzuwenden.The invention is in the field of electrically conductive connections and can be used in the structural design of a welded connection between an end electrode of a gas-filled discharge gap - such as a surge arrester or a switching spark gap - and a connecting wire.
Bei gasgefüllten Überspannungsableitern oder gasgefüllten Schaltfunkenstrecken mit napfartig ausgebildeten Endelektro- den ist es bekannt, die aus Kupfer bestehenden Endelektroden bei deren Herstellung durch Fließpressen emstuckig mit einem erhabenen, zapfenartigen Anschlußbereich zu versehen, der mittig zum Lötflansch der Endelektrode m deren napfartiger Vertiefung angeordnet ist (US 4,266,260 A) . Um eine sichere stoffschlüssige Verbindung zwischen diesem Anschlußbereich und dem einen Ende des Anschlußdrahtes durch Widerstands- schweißung zu gewährleisten, ist es weiterhin bekannt, den erhabenen Anschlußbereich m Abhängigkeit vom Durchmesser des Anschlußdrahtes m bestimmter Weise zu dimensionieren (EP 0 034 360 Bl / US 4,362,962 A) . - Bei der Herstellung derartiger Schweißverbindungen fließen relativ große Ströme, die eine erhebliche Erwärmung der Endelektrode bewirken und damit auch die angrenzende Lötstelle zum Isolator thermisch belasten. Diese Verbindungstechnik ist im übrigen bei Anschluß- drahten mit einem Durchmesser < 1 mm kaum noch anwendbar.In the case of gas-filled surge arresters or gas-filled switching spark gaps with cup-shaped end electrodes, it is known to provide the end electrodes, which are made of copper, with a raised, peg-like connection area, which is arranged in the center of the soldering flange of the end electrode with its cup-like depression, during their production by extrusion molding 4,266,260 A). In order to ensure a secure material connection between this connection area and one end of the connection wire by resistance welding, it is also known to dimension the raised connection area m in a specific manner depending on the diameter of the connection wire (EP 0 034 360 Bl / US 4,362,962 A ). - In the production of such welded connections, relatively large currents flow, which bring about considerable heating of the end electrode and thus also thermally stress the adjacent soldering point to the insulator. This connection technique can hardly be used for connection wires with a diameter <1 mm.
Ausgehend von einer elektrisch leitenden Verbindung mit den Merkmalen des Oberbegriffes des Patentanspruches 1 liegt der Erfindung daher die Aufgabe zugrunde, die StoffschlüssigeStarting from an electrically conductive connection with the features of the preamble of claim 1 The invention is therefore based on the object, the integral
Verbindung so auszugestalten, daß sie fertigungstechnisch einfacher hergestellt und auch für Drahtdurchmesser unter 1 mm eingesetzt werden kann.To design the connection so that it is easier to manufacture and can also be used for wire diameters of less than 1 mm.
Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß der erhabene Anschlußbereich mit einem axialen Sackloch versehen ist und daß der Anschlußdraht mit seinem einen Ende m das Sackloch eingeführt und mittels einer Laserschweißung mit dem erhabenen Anschlußbereich verbunden ist. Zweckmäßig werden mehrere Schweißpunkte gleichmäßig am Umfang verteilt vorgesehen .To achieve this object, it is provided according to the invention that the raised connection area is provided with an axial blind hole and that the connecting wire is inserted at one end into the blind hole and is connected to the raised connection area by means of laser welding. It is advisable to provide several welding spots evenly distributed over the circumference.
Eine derart ausgebildete stoffschlüssige Verbindung läßt sich infolge der an sich bekannten Verwendung eines Laserstrahles zur Zufuhr der Schweißenergie mit sehr hoher Reproduzierbarkeit der Schweißparameter und demzufolge auch mit sicherer Verbindungsquailtat herstellen. Die Koaxialität zwischen Anschlußdraht und Lötflansch der Elektrode ist dabei allein durch die Koaxialität des Sackloches zum Lötflansch bestimmt. Die Herstellung der Verbindung bringt eine nur geringe Warme- belastung des Abieiters mit sich. Die neue Verbindung kann dabei sowohl für galvanisch beschichtete oder unbeschichtete Elektroden aus Kupfer oder aus Eisen- oder Nichteisen- Legierungen, insbesondere Eisen-Nickel -Legierungen, als auch für blanke oder vernickelte oder verzinnte Kupferdrähte eingesetzt werden, wobei eine Nickel- oder Zmnbeschichtung den Absorptionsgrad für das Laserlicht verbessert. Hierzu kommen Schichtdicken von 1 bis 100 μm m Betracht. Eine Schichtdicke von 6 μm hat sich als vorteilhaft erwiesen. Für den Schweißvorgang ist dabei von Vorteil, daß der Laserstrahl sehr genau positioniert und hinsichtlich seiner Wärmeenergie dosiert werden kann, wobei während der Schweißung zunächst Material von der Kuppe des erhabenen Anschlußbereiches aufgeschmolzen wird, daß sich dann mit dem anschließend aufschmelzenden Material des Drahtendes verbindet.Such a cohesive connection can be produced as a result of the known use of a laser beam for supplying the welding energy with very high reproducibility of the welding parameters and consequently also with a reliable connection quality. The coaxiality between the connecting wire and the soldering flange of the electrode is determined solely by the coaxiality of the blind hole to the soldering flange. Establishing the connection involves only a small amount of heat on the drain. The new connection can be used both for galvanically coated or uncoated electrodes made of copper or of iron or non-ferrous alloys, in particular iron-nickel alloys, as well as for bare or nickel-plated or tinned copper wires, with a nickel or tin coating the degree of absorption improved for the laser light. Layer thicknesses of 1 to 100 μm m are considered. A layer thickness of 6 μm has proven to be advantageous. It is advantageous for the welding process that the laser beam can be positioned very precisely and its thermal energy can be metered, with material initially during the welding is melted from the tip of the raised connection area, that then connects to the subsequently melting material of the wire end.
Der gemäß der Erfindung vorgesehene Anschlußbereich der Endelektrode kann zylindrisch ausgebildet sein. Vorteilhaft ist jedoch eine Ausgestaltung als Kegelstumpf, weil dann der Laserstrahl so positioniert werden kann, daß er vorzugsweise rechtwinklig auf die Mantelfläche des Kegelstumpfes auf- trifft; m diesem Fall ist eine optimale Wärmeabsorption gegeben.The connection area of the end electrode provided according to the invention can be cylindrical. However, an embodiment as a truncated cone is advantageous because the laser beam can then be positioned such that it preferably strikes the lateral surface of the truncated cone at a right angle; In this case, optimal heat absorption is given.
Die Abmessungen des kegelstumpfformigen Anschlußbereiches sollten bei Drahtdurchmessern von 0,5 bis 3 mm innerhalb fol- gender Grenzen liegen:The dimensions of the frustoconical connection area should be within the following limits for wire diameters of 0.5 to 3 mm:
Kegelwinkel α: 30 bis 80 °,Cone angle α: 30 to 80 °,
Höhe h: 0,2 bis 3 mm,Height h: 0.2 to 3 mm,
Basisdurchmesser D: 1 bis 8 mm;Base diameter D: 1 to 8 mm;
Stumpfdurchmesser d: 0,5 bis 7 mm; Tiefe d des Sackloches: 0,2 bis 16 mm.Die diameter d: 0.5 to 7 mm; Depth d of the blind hole: 0.2 to 16 mm.
Mit Rücksicht auf eine einfache Herstellbarkeit der Endelektroden durch Kaltfließpressen sollte das Sackloch dabei leicht konisch ausgebildet sein.In view of the fact that the end electrodes can be easily manufactured by cold extrusion, the blind hole should be slightly conical.

Die Figuren 2 bis 6 zeigen weiterhin mehrere Ausführungsbeispiele für eine Endelektrode mit erhabenen Anschlußbereich und Figur 7 eine Variante für die Ausgestaltung des zu verschweißenden Endes eines Anschlußdrah- tes.An exemplary embodiment of the new welded connection is shown in FIG. 1.
