Definitions
- the invention is in the field of electrically conductive Connections and is one in the design Welded connection between an end electrode of a gas-filled Discharge path - like a surge arrester or a switching spark gap - and a connecting wire.
- connection technology is in the rest of connection wires with a diameter ⁇ 1 mm hardly applicable.
- the invention is therefore based on the object, the integral Design the connection so that it is manufacturing technology Easier to manufacture and also for wire diameters under 1 mm can be used.
- the raised connection area with an axial blind hole is provided and that the connecting wire with one end inserted into the blind hole and by means of laser welding is connected to the raised connection area. expedient several welding spots are evenly distributed around the circumference intended.
- a cohesive connection formed in this way can be due to the known use of a laser beam for the supply of welding energy with very high reproducibility the welding parameter and consequently also with safer Establish connection quality.
- the coaxiality between lead wire and the solder flange of the electrode is alone determined by the coaxiality of the blind hole to the solder flange.
- the establishment of the connection brings only a small heat load of the arrester with itself.
- the new connection can both for galvanically coated or uncoated Electrodes made of copper or of iron or non-ferrous alloys, especially iron-nickel alloys, as well used for bare or nickel-plated or tinned copper wires be, with a nickel or tin coating the Absorbance for the laser light improved.
- a layer thickness of 6 ⁇ m has proven to be advantageous.
- the laser beam is very accurate positioned and metered in terms of its thermal energy can be, with material initially during welding melted from the top of the raised connection area is that then with the subsequent melting material of the wire end connects.
- connection area of the end electrode provided according to the invention can be cylindrical. It is advantageous however, a configuration as a truncated cone, because then the laser beam can be positioned so that it is preferred strikes the surface of the truncated cone at right angles; in this case there is an optimal heat absorption.
- the dimensions of the frustoconical connection area should be within the following limits for wire diameters of 0.5 to 3 mm: Cone angle ⁇ 30 to 80 °, Height h 0.2 to 3 mm, Base diameter D 1 to 8 mm; Die diameter d 0.5 to 7 mm; Depth d of the blind hole 0.2 to 16 mm.
- the blind hole should be cold extruded be slightly conical.
- FIG. 1 An embodiment of the new welded connection is in Figure 1 shown.
- Figures 2 to 6 also show several embodiments for an end electrode with raised Connection area and Figure 7 a variant for the design of the end of a connecting wire to be welded.
- the 1 is a gas-filled surge arrester 1, that of a ceramic insulator 2 and the two end electrodes 11 and 12 is provided with two connecting wires 3, the each axially cohesive with the end electrodes 11 and 12 are connected.
- Each end electrode has a solder flange 13 and is centered on this soldering flange within a calotte 15 provided with a raised connection area 14, in which is the welding point 5.
- the sublime Connection area 14 provided with a blind hole 16, in the one end of the lead wire 3 is inserted.
- the sublime Connection area 14 is designed as a truncated cone, wherein for welding this connection area to the connection wire a laser beam 4 incident at an angle ⁇ the lateral surface of the raised connection area directed has been.
- the raised connection area according to FIG. 3 can be used for electrode bodies without dome one axially over the solder flange 13 protruding truncated cone 17, or one according to Figure 4 Cylinder stump 18.
- the raised connection area can also be made in this way be designed so that the truncated cone 19 has a crown width of b has 0 mm.
- the raised connection area can be designed as a hollow cylindrical socket-shaped insert 20 be formed, the inserted into a corresponding hole in the electrode body or is soldered.
