Definitions
- the invention initially relates to a fuse link, in particular for low-voltage high-performance fuses, NH fuses, which has at least one fuse element with a solder substance in a solder deposit of a carrier, specifically according to the preamble of claim 1.
- the solder is on the base is made of tin and the base is made of copper.
- fuse links are common on the market.
- a tin-cadmium alloy is usually used as the solder substance.
- SnCd 80 ie an alloy with 80 percent by weight tin and 20 percent by weight cadmium, is common. Recently, one would like to avoid cadmium for reasons of environmental protection.
- fuse links on the market whose fusible conductors have a solder substance made of SnBi 95 5. The melting times of the fusible conductors provided with this solder vary considerably more than those with the conventional SnCd solders.
- SnBi solders generally tend to melt away. To prevent this, the solder is covered with a silicone-containing layer in a fuse link on the market. The extinguishing behavior of the fuse link when the silicone decomposes can deteriorate significantly as a result of the carbon atoms.
- the fusible conductor and solder system should generally be designed so that if overflows are present for a longer period of time, the solder melts locally, dissolves the material of its carrier, ie the contact conductor, and thus speeds up the shutdown. This is usually referred to as an M effect.
- the solder should meet the following conditions: - Adequate solubility of the solder substance for the fuse element material, usually copper,
- An organic coating has already been provided as a solder stopping agent, which is intended to prevent the solder from flowing away in the case of a solder substance without cadmium.
- solder stopping agent which is intended to prevent the solder from flowing away in the case of a solder substance without cadmium.
- the invention is based on the object of developing a fuse link which works with a cadmium-free solder on the fuse element and in which the problems described, in particular the scattering of the switch-off values and the flow of the solder, are improved so that the otherwise good properties of cadmium-containing ones Fusible conductor systems can be achieved.
- a fuse link according to claim 1.
- the solder contains as an active substance a tin alloy with two further constituents, a first constituent by weight percentage being larger but being smaller by weight percentage than the proportion the basic substance tin, is then selected to lower the melting temperature of the solder.
- a second component, smaller by weight percent, is a substance that does not dissolve in the tin, where due to the formation of crystallization nuclei on cooling from the liquid to the solid state, which result in a fine structure and prevent coarsening of the structure under load on the fuse.
- Such a fusible link solder system can be tuned to have a scattering behavior similar to that using cadmium and suitable response times.
- the fine structure obviously promotes the dissolution of the carrier material, i.e. the fuse element, which means that the same melting times and the same melting behavior as for fuse elements with conventional cadmium-containing ones
- Fusible conductor solders can be achieved. As a result, the melting process is not subjected to separate energy conversion, so that additional heating does not occur.
- Claims 2 to 6 relate to advantageous developments of the solder fusible link system.
- the invention is based on the further object of further developing a cadmium-free fuse link in such a way that the solder is promoted in its resistance to flow.
- the described object is achieved by a fuse link according to claim 7.
- the solder as solder material in the solder depot of a carrier, and / or the carrier is provided with an oxide skin.
- the oxide skin can be formed thermally or chemically. It is sufficient if the oxide skin is formed in the boundary area between the solder and the carrier.
- the wetting of the carrier can also be controlled as desired by the geometry of the oxidized areas.
- the invention further relates to a method for producing a fuse link, according to which solder and / or carrier are subjected to a thermal treatment in an oxidizing atmosphere.
- a method for producing a fuse link is also provided, according to which the solder and / or the carrier is treated with a substance affine to the solder and / or carrier.
- a sodium sulfide solution is particularly suitable for this.
- a substance affine to the solder and / or carrier can be applied between absorbent rollers and impregnated with the affine substance.
- solder material consisting of a tin-bismuth-copper alloy, a tin-indium-copper alloy or a tin-bismuth-iron alloy.
- a solder material which has a tin-bismuth-copper alloy with 10% to 30% bismuth and 0.3% to 1.0% copper, together with tin 99.5%, the rest usual impurities, has proven to be particularly advantageous having.
- melting tests are plotted in a diagram, with a conventional tin-cadmium-solder substance being illustrated in its switch-off behavior over several tests according to the prior art for comparison.
- the switch-off behavior of tin-bismuth copper at various proportions is illustrated.
- FIG. 2 a comparison is shown, on the left for cadmium-free solder without copper, on the right for an embodiment according to the invention with cadmium-containing solder and tin-bismuth with copper, a fusible conductor with a constriction in front of a solder depot after the fusible conductor responds and when the fusible conductor is interrupted.
- the response time of the fuse element is on the ordinate in seconds until it is interrupted tin alloys with the specified constituents and their proportions are plotted on the abscissa. The results are plotted over several tests.
- Copper served as the carrier for the solder.
- Tin-cadmium serves as an orientation value.
- bismuth is a proportion in weight percentages of 25%, 15% and 5% respectively under a load of 32 A phase current, in this case equivalent to 1.6 times the rated current, wor ⁇ examines the.
- the proportions of copper are each ' 0.8%.
- the proportion of tin in the difference is 99.5%, with the rest making up common impurities.
- the first further component of the tin alloy is in a smaller proportion than the proportion of the basic substance tin. This component lowers the melting temperature of the solder. Bismuth was used for this in the present case.
- a second component, which is smaller by weight percent, is a substance that does not dissolve in the tin, which causes crystallization nuclei when cooling from the liquid to the solid state, which result in a fine structure. Copper was used here.
- the diagram according to FIG. 1 shows the scattering behavior of the respective alloy and, for a specific geometry of the fusible conductor, with a constriction in front of the solder, the time until the device responds and until it is switched off. These times can be strongly influenced by the geometry of the fusible conductor and, if applicable, the type and dimensioning of a constriction in front of the solder for a planned current load and when using a specific alloy for the solder.
- Fuse links with a solder substance of the fuse element made of tin-bismuth-copper alloy, made of tin-indium-copper alloy and made of tin-bis uth-iron alloy have proven to be very suitable.
- a tin-indium-copper alloy with the components in the ratio and by weight percent has also proven to be favorable: Sn from 70% to 96%, In from 3% to 30%, Cu from 0.3% to 5.0% ,
- FIG. 2 shows an interrupted constriction in front of the solder depot for a fusible conductor of the same geometric configuration, each in enlarged form, the largest
- Width of the fuse element in nature is 14 mm.
- a solder made of tin-bismuth with about 75% tin and 25% bismuth was used for a copper fusible conductor.
- a total of 99.5%, at 0.5% is usual Impurities, the situation after Interruption of the fusible conductor reproduced by the action of solder.
- solder and attacked fusible conductor have a fine structure and clean contours in the micrograph. The energy turnover when the fusible conductor melts is thus kept low and the formation of heat cracks is avoided.
- the behavior of the three-component alloys provided can be further promoted by an oxide skin on the solder in the solder depot and / or on the fuse element, at least in the vicinity of the solder depot.
- an oxide skin can prevent the melting solder from flowing off when the fuse element responds in the fuse link. This measure of using an oxide skin in a targeted manner can generally be used for solders that are not inherently stationary, regardless of the usual structure of the solder or the alloy serving as solder.
- Such an oxide skin can be formed thermally or chemically.
- Carriers are treated in an oxidizing atmosphere. You can work with local heat, for example through a clamp.
- Substances affine to the solder or to the carrier are suitable for chemical treatment.
- the fusible conductor can be treated with a sodium sulfide solution. In the simplest case, this can be done by brushing or by absorbent rollers soaked in the affine substance, which roll over the fusible conductor at the desired location. To prevent the solder from flowing out even more reliably, it is sufficient to carry out an oxidation only in the area of the solder and the adjacent areas of the carrier.
- Cadmium-free solder materials for fuse links can advantageously be a tin-bismuth-copper alloy, a tin Indium-copper alloy or a tin-bismuth-iron alloy. Without considering a geometrical configuration of the fuse element, it is advantageous if the proportions are as follows, each in percent by weight:
