Definitions
- 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.
- connection technique can hardly be used for connection wires with a diameter ⁇ 1 mm.
- connection so that it is easier to manufacture and can also be used for wire diameters of less than 1 mm.
- 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.
- 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 ⁇ m m are considered. A layer thickness of 6 ⁇ m 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.
- connection area of the end electrode provided according to the invention can be cylindrical.
- 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.
- the dimensions of the frustoconical connection area should be within the following limits for wire diameters of 0.5 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 slightly conical.
- FIG. 1 An exemplary embodiment of the new welded connection is shown in FIG. 1.
- FIGS. 2 to 6 also show several exemplary embodiments for an end electrode with a raised connection area and
- FIG. 7 shows a variant for the configuration of the end of a connection wire to be welded.
- a gas-filled surge arrester 1 which consists of a ceramic insulator 2 and the two end electrodes 11 and 12, is provided with two connecting wires 3, which are axially connected to the end electrodes 11 and 12 in a cohesive manner.
- Each end electrode has a solder flange 13 and is provided in the center of this solder flange within a dome 15 with a raised connection area 14, in which the welding point 5 is located.
- the raised connection area 14 is provided with a blind hole 16, through which one end of the connection wire 3 is inserted.
- the raised connection area 14 is designed as a truncated cone, a laser beam 4 incident at an angle ⁇ being directed onto the lateral surface of the raised connection area to weld this connection area to the connection wire.
- connection area located centrally and thus concentrically to the soldering flange 13 of the end electrode 12 is characterized by the following parameters:
- the raised connection area according to FIG. 3 can form a truncated cone 17 projecting axially beyond the soldering flange 13 in the case of electrode bodies without a spherical cap, or a cylindrical stub 18 according to FIG.
- the raised connection area can also be designed such that the truncated cone 19 has a tip width of b equal to 0 mm.
- the raised connection area can be designed as a hollow cylindrical, bush-shaped insert 20 which is inserted or soldered into a corresponding bore in the electrode body.
- the wire end of the wire 31 to be soldered to the raised termination area can be provided with an upset nail head 32 and a pin 33 in order to solder the wire to a connection area which, according to FIG. 4, is cylindrical and has a relatively wide tip.
