Description
Technical field
The present invention relates to a kind of melt for direct current fuse link.
Background technology
Semiconductor equipment protection fuse-link is as the use of the short-circuit protection of the complete set of equipments of rectifying installation and relevant device (comprising frequency converter, soft start etc.), semiconductor element and composition thereof; and its most crucial parts are exactly melt, in fuse-link, play vital effect.
Refer to Fig. 1, Fig. 1 is semiconductor protection fuse-link conventional at present and the melt of direct current fuse link, melt body 1' offers the aperture 2' that ordered series of numbers is measure-alike, when larger short circuit current is by melt, narrow neck 3' between two often adjacent row apertures 2 is heated rapidly due to heating effect of current, and local temperature raises rapidly until melt fusing is with a point deenergizing; But it is slow that this melt shortcoming is fusing speed, blocks poor performance, simultaneously relative to be in the time in overload procedure be at fuse-link longer.
Summary of the invention
The object of the invention is the defect overcoming prior art, a kind of melt for direct current fuse link is provided, reliable protection can be provided for associated straight current circuit and components and parts.
The technical scheme realizing above-mentioned purpose is: a kind of melt for direct current fuse link, comprises two melt bodies, each described melt body all offers ordered series of numbers first hole and ordered series of numbers second hole, and the size in described first hole is less than the size in described second hole;
Described in first hole described in ordered series of numbers and ordered series of numbers, the second hole is distributed on corresponding described melt body from left to right;
Described two melt bodies are connected in partly overlapping mode, and the overlapping of described two melt bodies is distributed with two row first holes and from left to right and arranges the 3rd hole, and described 3rd hole is overlapped to form by two the second bore portions.
Above-mentioned a kind of melt for direct current fuse link, wherein, described first hole is rounded, and described second hole is rounded, and the aperture in described first hole is less than the aperture in described second hole.
Above-mentioned a kind of melt for direct current fuse link, wherein, often row first hole and and row second hole adjacent on the right side of it between narrow neck be less than every row second hole and and row first hole adjacent on the right side of it between narrow neck.
Above-mentioned a kind of melt for direct current fuse link, wherein, the narrow neck between two row first holes of the overlapping of described two melt bodies be less than described 3rd hole and and row first hole adjacent on the left of it between narrow neck.
Above-mentioned a kind of melt for direct current fuse link, wherein, described two melt bodies are formed in one structure.
Above-mentioned a kind of melt for direct current fuse link, wherein, each described melt body all adopts fine silver material to make.
Melt for direct current fuse link of the present invention, melt body offers ordered series of numbers ordered series of numbers first hole and ordered series of numbers second hole, first hole is different with the second hole dimension, when larger short circuit current is by melt, electric current is first by larger narrow road, again through less narrow road, until the narrow road that electric current is overlapping in the middle of two melt bodies, deenergizing can be divided fast; But when less overload current is by melt, less narrow road can disconnect melt rapidly and by breaking current.
Melt for direct current fuse link of the present invention, compared with prior art, tool has the following advantages
1, the fusing speed of melt is fast, and it is good to block performance, effectively can reduce fuse-link simultaneously and be in time in overload procedure be, can provide reliable protection for associated straight current circuit and components and parts;
2, operating chacteristics is stablized, more reliable to the protection of circuit;
3, melt design improves electrical property and hot property, and operating temperature rise and heat-sinking capability are obtained for improvement;
4, aim at the design of protection DC circuit, more can be competent at the protection task of DC circuit occasion.

Embodiment
In order to make those skilled in the art can understand technical scheme of the present invention better, below in conjunction with accompanying drawing, its embodiment is described in detail:
Refer to Fig. 2, Fig. 3 and Fig. 4, most preferred embodiment of the present invention, a kind of melt for direct current fuse link, comprise two melt bodies 1, the size each melt body 1 all offering ordered series of numbers first hole 2 and hole 2, ordered series of numbers second hole 3, first is less than the size in the second hole 3, and the first hole 2 is rounded, second hole 3 is rounded, and the aperture in the first hole 2 is less than the aperture in the second hole 3; Ordered series of numbers first hole 2 and ordered series of numbers second hole 3 are distributed on corresponding melt body 1 from left to right; Two melt bodies 1 are connected in partly overlapping mode, and the overlapping of two melt bodies 1 is distributed with two row first holes 2 and from left to right and arranges the 3rd hole 4, and the 3rd hole 4 is partly overlapped by two the second holes 3 and formed.Two melt bodies 1 are formed in one structure.Each melt body 1 all adopts fine silver material to make, and has excellent to block performance.
Often row first hole 2 and and row second hole 3 adjacent on the right side of it between narrow neck 5 be less than every row second hole 3 and and row first hole 2 adjacent on the right side of it between narrow neck 6.Often row first hole 2 and and row second hole 3 adjacent on the right side of it between narrow neck 5 be less narrow road, often row second hole 3 and and row first hole 2 adjacent on the right side of it between narrow neck 6 be larger narrow road.
Narrow neck 7 between two row first holes 2 of the overlapping of two melt bodies 1 be less than the 3rd hole 4 and and row first hole 2 adjacent on the left of it between narrow neck 8.
Melt for direct current fuse link of the present invention, melt adopts fine silver material, punching becomes the shape of variable cross-section, and have the aperture that ordered series of numbers diameter differs, especially the circular hole lap of the centre of two melt bodies, exactly because the part of the aperture having had diameter to differ and middle circular hole overlap, make it better for direct current fuse link.
Melt for direct current fuse link of the present invention, in use, when larger short circuit current is by melt, electric current is first by larger narrow road 6, again through less narrow road 5, until the narrow road that electric current is overlapping in the middle of two melt bodies 1, deenergizing can be divided fast; But when less overload current is by melt, less narrow road 5 can disconnect melt rapidly and by breaking current.The fusing speed of such melt is fast, and it is good to block performance, effectively can reduce fuse-link simultaneously and be in time in overload procedure be, can provide reliable protection for associated straight current circuit and components and parts.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
