Definitions
- the invention is in the field of electrical components and can be used in the material design of the outer surface of gas discharge surge arresters which have at least one tubular ceramic insulator and electrodes arranged at the ends of the ceramic insulator and gas-tightly connected to the ceramic insulator and connected to the ceramic insulator are provided with a metallic protective layer.
- Gas discharge surge arresters are used, among other things, to protect communication lines.
- Surge arresters are used, on whose electrodes connection wires are soldered, welded or molded.
- Such surge arresters can have two electrodes opposing each other and, if appropriate, a third annular electrode arranged in the middle (DE-Al-28 28 650).
- the connecting wires connected to the electrodes like the electrodes, are usually silver-plated, provided that they consist of copper. Sometimes it is also required to use tin-plated connecting wires. This facilitates the wetting of the connecting wires during the soldering process by means of wave soldering.
- bronze Cu-Sn alloy
- the electrodes are contacted under spring force.
- surge arresters with alloyed iron electrodes and, if necessary, to coat these electrodes with a nickel layer.
- the object of the invention is to provide a surge arrester create, which can be manufactured inexpensively and handled as an automatically processable bulk material without impairing the insulation strength and which can optionally be soldered into printed circuits or printed circuit boards without problems.
- the electrodes are tinned and that an annular protective layer, which is not interrupted in the axial direction of the ceramic insulator and is made of an acid and heat-resistant paint or varnish application, is applied to the outer surface of each ceramic insulator whose width is at least 1 mm.
- the tinning forms an inexpensive metallic protective layer for the electrodes.
- Such tinning entails the risk that when the surge arrester is handled as bulk material, the tin coating is abraded on the rough surface of the ceramic insulator and the occurrence of insulation faults is thus promoted.
- Applying the ring-shaped protective layer from a paint or varnish application eliminates this danger.
- the annular protective layer forms a relatively smooth surface area on the surface of the ceramic insulator, on which no harmful tin abrasion is possible.
- the ring-shaped protective layer is in its width is dimensioned such that the minimum value of the insulation strength (for example 10 ohms) is maintained, even if tin abrasion is present on the other surface areas of the ceramic insulator.
- the ring-shaped protective layer can optionally cover the entire outer surface of the ceramic insulator.
- this protective layer can be designed as a negative pressure, i. H. the protective layer also forms the label.
- the protective layer can, however, also form a transparent, preferably colorless cover layer for customary printing or a base for subsequent customary printing.
- the acid resistance of the annular protective layer enables the use of galvanic treatments of the surge arrester provided with the annular protective layer, which are required in the further course of the manufacture of the surge arrester.
- the heat resistance of the annular protective layer suitably at least 160 * C, on the other hand ensures that the ring-shaped protective layer spruchung particularly in Kirstrombean- of the device is not affected (Verfär ⁇ environment).
- Commercially available air-drying one-component lacquers are preferably considered as the acid-resistant and heat-resistant lacquer for the annular protective layer.
- Printing inks are particularly suitable as acid and heat-resistant inks.
- a surge arrester designed in accordance with the invention can also be provided with tin-plated connecting wires so that it can be arranged on printed circuit boards and soldered to conductor tracks.
- the use of tinned connecting wires ensures problem-free soldering in printed circuits or in printed circuit boards using the soldering method. at If connecting wires are not molded onto the electrodes, they can be tinned with the electrodes before they are connected, in particular soldered. The tin plating of the connecting wires can also take place together with the tin plating of the electrodes.
- FIGS. 1 to 4 Three exemplary embodiments of gas discharge surge arresters designed according to the invention are shown in FIGS. 1 to 4. It shows
- FIG. 1 shows an overvoltage arrester with two electrodes and connecting wires
- FIG. 2 shows an overvoltage arrester with three electrodes and connecting wires
- FIGS. 3 shows a detail of an annular protective layer designed as a negative pressure for the exemplary embodiment according to FIGS.
- Figure 4 shows a surge arrester without connecting wires.
- the surge arrester 1 consists of the tubular ceramic insulator 2 with electrodes 3 and 4 arranged at its ends.
- the electrodes are soldered to the ceramic insulator 2 in a gas-tight manner.
- the connecting wires 5 and 6 made of copper are also welded to the electrodes, which are made of copper.
- a lacquer layer 7 has been applied to the outer surface of the ceramic insulator 2 using a conventional printing method. This lacquer layer covers the entire outer surface of the ceramic insulator and has a width of approximately 5 mm. A width of 1 mm would already be sufficient. With a width that is less than the outer distance between the two electrodes 3 and 4, the annular protective layer can be arranged in the center or off-center to the electrodes 3 and 4.
- connection wires 5 and 6 had been welded to the electrodes, the surge arrester was subjected to a galvanic treatment with which a tin layer 8 was deposited on the outer surface of the electrodes 3 and 4 and on the connection wires 5 and 6.
- FIG. 2 shows a gas discharge surge arrester 10 with three electrodes.
- the conductor consists of the two tubular ceramic insulators 11 and 12, which are connected coaxially to one another by means of the ring electrode 13.
- the electrodes 14 and 15 are arranged at the two other ends of the ceramic insulators 11 and 12.
- the connecting wires 16, 17 and 18 are welded to these electrodes and to the ring electrode 13. Electrodes and connecting wires are made of copper.
- the ceramic insulators 11 and 12 are each provided with a lacquer layer 19 after their gas-tight connection to the electrodes 14 and 15. After the connection wires were welded to the electrodes, the
- a tin layer 20 has been deposited on the electrodes and the connecting wires.
- the lacquer application 7 on one of the two ceramic insulators of Figure 2 is on the ceramic insulator 2 according to ' Figure 1 and 19th
- a negative print is shown in detail in FIG. 3 and provided with the reference symbol 21.
- the ceramic insulator can also be provided with a normal positive marking and with a colorless or translucent lacquer application applied over it.
- FIG. 4 shows a surge arrester 30 with two electrodes 31 and 32 and with a ceramic insulator 33. There are no connecting wires.
- the electrodes 31 and 32 consist of copper and are provided with a tin layer 34.
- An annular protective layer 35 with a width of approximately 2 mm is applied to the ceramic insulator 33.
