Play the role of vital.
Referring to Fig. 1, Fig. 1 is the current conventional semiconductor protection fuse-link i.e. melt of direct current fuse link, in melt
The identical aperture 2' of ordered series of numbers size is offered on ontology 1', it is small per two adjacent column when biggish short circuit current passes through melt
Narrow neck 3' between hole 2 is since heating effect of current is heated rapidly, and local temperature increases rapidly until melt fuses with disjunction electricity
Road；But for the melt the disadvantage is that fusing speed is slow, truncation performance is poor, at the same it is opposite fuse-link be in overload procedure the time compared with
It is long.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of existing technologies, a kind of melt for direct current fuse link, Ke Yiwei are provided
Related DC circuit and component provide reliable protection.
Realizing the technical solution of above-mentioned purpose is: a kind of melt for direct current fuse link, including two melt ontologies, often
The second hole of the first hole of ordered series of numbers and ordered series of numbers is offered on a melt ontology, the size in first hole is less than second hole
Size；
Second hole described in first hole and ordered series of numbers described in ordered series of numbers is distributed in from left to right on the corresponding melt ontology；
Described two melt ontologies are connected in a manner of partly overlapping, and the overlapping of described two melt ontologies is from left to right
Two the first holes of column and a column third hole are distributed with, and the third hole is overlapped to form by two the second bore portions.
Above-mentioned a kind of melt for direct current fuse link, wherein first hole is rounded, and second hole is in circle
Shape, and the aperture in first hole is less than the aperture in second hole.
Above-mentioned a kind of melt for direct current fuse link, wherein the first hole of each column and arrange the with its right side adjacent one
Narrow neck between two holes is less than the narrow neck between the second hole of each column and first hole of column adjacent with its right side.
Above-mentioned a kind of melt for direct current fuse link, wherein positioned at the two of the overlapping of described two melt ontologies
Narrow neck between the first hole of column is less than the narrow neck between the third hole and first hole of column adjacent with its left side.
Above-mentioned a kind of melt for direct current fuse link, wherein described two melt ontologies are an integral molding structure.
Above-mentioned a kind of melt for direct current fuse link, wherein each melt ontology is all made of fine silver material system
At.
Melt for direct current fuse link of the invention offers the first hole of ordered series of numbers ordered series of numbers and ordered series of numbers on melt ontology
Two holes, the first hole and the second pore size difference, when biggish short circuit current passes through melt, electric current first passes through biggish narrow road,
Again through lesser narrow road, until when narrow road of the electric current by two melt ontology centre overlappings, it can quick disjunction circuit；But work as
When lesser overload current passes through melt, lesser narrow road can disconnect rapidly melt and by breaking current.
Melt for direct current fuse link of the invention has the following advantages that compared with prior art
1, the fusing speed of melt is fast, and truncation performance is good, can simultaneously be effectively reduces fuse-link and is in overload procedure
Time, reliable protection can be provided for associated straight current circuit and component；
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 all improved；
4, protection DC circuit design is aimed at, the protection task of DC circuit occasion can be more competent at.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the conventional melt for direct current fuse link；
Fig. 2 is the structural schematic diagram of the melt for direct current fuse link of the invention；
Fig. 3 is the partial enlarged view of part A in Fig. 2；
Fig. 4 is the partial enlarged view of part B in Fig. 2.
Specific embodiment
It is right with reference to the accompanying drawing in order to make those skilled in the art be better understood when technical solution of the present invention
Its specific embodiment is described in detail:
Please refer to Fig. 2, Fig. 3 and Fig. 4, highly preferred embodiment of the present invention, a kind of melt for direct current fuse link, including two
A melt ontology 1 offers the first hole of ordered series of numbers 2 and the second hole of ordered series of numbers 3 on each melt ontology 1, and the size in the first hole 2 is less than
The size in the second hole 3, the first hole 2 is rounded, and the second hole 3 is rounded, and the aperture in the first hole 2 is less than the aperture in the second hole 3；Number
The first hole of column 2 and the second hole of ordered series of numbers 3 are distributed in from left to right on corresponding melt ontology 1；Two melt ontologies 1 are with part
The mode of overlapping is connected, and two column the first holes 2 and a column third hole 4 are distributed in the overlapping of two melt ontologies 1 from left to right, and
Third hole 4 is partly overlapped by two the second holes 3 and is formed.Two melt ontologies 1 are an integral molding structure.Each melt ontology 1 is
It is made of fine silver material, there is excellent truncation performance.
The first hole of each column 2 and the narrow neck 5 between its adjacent second hole of column 3 in right side be less than the second hole of each column 3 and with
Narrow neck 6 between adjacent first hole of column 2 in its right side.Between the first hole of each column 2 and second hole of column 3 adjacent with its right side
Narrow neck 5 be lesser narrow road, the second hole of each column 3 and the narrow neck 6 between its adjacent first hole of column 2 in right side are biggish
Narrow road.
Narrow neck 7 between two the first holes of column 2 of the overlapping of two melt ontologies 1 be less than third hole 4 and with its left side
Narrow neck 8 between adjacent first hole of column 2 in side.
Melt for direct current fuse link of the invention, melt use fine silver material, and punching and has at the shape of variable cross-section
The different aperture of ordered series of numbers diameter, the circular hole lap of the centre of especially two melt ontologies, exactly because there is diameter not
The part of one aperture and intermediate circular hole overlapping, is allowed to preferably be used for direct current fuse link.
Melt for direct current fuse link of the invention, when in use, when biggish short circuit current passes through melt, electric current
Biggish narrow road 6 is first passed through, then through lesser narrow road 5, until when electric current passes through the narrow road being overlapped among two melt ontologies 1,
It can quick disjunction circuit；But when lesser overload current passes through melt, lesser narrow road 5 can disconnect rapidly melt and will
Breaking current.The fusing speed of melt in this way is fast, and truncation performance is good, can simultaneously be effectively reduces fuse-link and is in overload procedure
In time, reliable protection can be provided for associated straight current circuit and component.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
