Definitions
- the present invention relates to fuse technology. It relates, more particularly, to a flat - or blown fuse element - intended, in particular, to react to low current overloads but of long duration.
- the invention also relates to a method of manufacturing such a fuse element.
- the object of the present invention is to provide a blown fuse element structure which, in particular, improves the effectiveness of the "M point" effect and greatly simplifies its manufacture.
- the fuse element according to the invention consists of a plate comprising at least three coplanar parts and of the same thickness joined by welding, namely: a central metal part comprising a portion with a high melting point and a portion with a low melting point embedded in the portion with a high melting point, and
- the plate comprises, in series, a plurality of central parts each arranged between two lateral parts.
- the central part consists of a core with low melting point and a sheath with high melting point surrounding the core.
- the central part consists of a bundle of strands with a low melting point and a matrix with a high melting point surrounding the strands.
- the portion with a low melting point of the central part essentially comprises tin
- the portion with a low melting point is a tin-silver or tin-zinc alloy comprising from 80 to 98% tin; - the portion with low melting point occupies 15 to 60% by weight of the central part;
- the high melting point portion of the central part is made of copper or silver
- the side parts are made of copper or silver; and - particularly advantageously, the lateral parts are made of copper and the high melting point portion of the central part is made of silver.
- the method according to the invention is characterized in that the parts of the fuse element are formed and joined by rolling.
- the central part can either come from a sheathed wire having a core with low melting point surrounded by a sheath with high melting point, or come from a composite wire formed by a bundle of strands at low melting point embedded in a high melting point matrix.
- FIGS. 1 and 2 represent two embodiments of the fuse element
- FIG. 3 shows a fuse element with several central parts.
- FIG. 1 shows, at 10, a fuse element in the form of a thin elongated plate having, typically, a length of 10 to 100 mm, a width of 2 to 15 mm and a thickness of 0.02 to 0.5 mm.
- This plate generally comprises, in a conventional manner, notches or holes which reduce the section thereof so as to optimize the short-circuit function of the fuse.
- the plate 10 cut from a strip, has three coplanar parts, juxtaposed in the direction of its length and joined by welding, namely: - a central part 12 having, typically, a length of 2 to 10 mm, and
- the side parts 14 are made of a metal having good electrical conductivity and a high melting point, such as copper and silver.
- the central part 12 consists of a core 16, of roughly rectangular section, and of a sheath 18 surrounding the core. This occupies 15 to 60% by weight of the central part 12, the sheath 18 therefore occupying 40 to 85%.
- the core 16 is essentially formed from a metal with a low melting point, advantageously tin. As an indication, it can be a tin-silver or tin-zinc alloy comprising from 80 to 98% tin.
- the sheath 18 is essentially formed from a metal having good electrical conductivity and a high melting point, such as copper and silver.
- the plate 10 always has a central portion 12 and two side portions 14. These are identical to those of the embodiment of Figure 1, but the central portion
- the strands 20 occupy 15 to 60% by weight of the central part 12, the matrix 22 therefore occupying 40 to 85%.
- the strands 20 are of the same nature as the core 16 and the matrix 22 of the same nature as the sheath 18. Thus is produced, according to two different modes illustrated by Figures 1 and 2, a fuse element in which the "point M" is intimately integrated into its copper or silver portion sensitive to strong current overloads.
- the two lateral parts are made of copper, while the portion with a high melting point of the central part is made of silver
- the laminated structure has copper on the outside and silver on the inside, it is interesting to note that at their junction with the central silver part 12, the two lateral copper parts 14 have convex ends. . This is simply due to the fact that the silver in the central part is less hard than copper or the silver in the side parts. During rolling, they therefore encroach on the central part.
- FIG. 3 shows a plate 10 ′ according to the invention comprising several central parts 12, three in number in the embodiment shown, each inserted between two lateral parts 14.
- the central parts 12 may consist either of, as shown in FIG. 3, a core 16 and a sheath 18 surrounding it, or, as shown in FIG. 2, of a bundle of strands 20 distributed in a matrix 22.
- Such a structure may be preferred for certain applications, in particular because it allows a faster response to overloads.
