Description
Technical field
The present invention relates to a kind of fuse and manufacture method thereof.
Background technology
The traditional insurance silk generally is used for electronic product, via by fuse pass through electric current excessive, smelting part thereby fusing are used for avoiding circuit that danger such as thermal ignition took place, purpose is protecting people and equipment not to damage because of overcurrent, even breaking out of fire.Moreover, at present along with electric equipment is compact, function becomes increasingly complex, the part that needs is more and more, and circuit and electronic component on the circuit board are also more and more intensive, so the circuit of circuit substrate trends towards miniaturization, miniature the adopting of electronic component, be the normality using method, it can make the part of circuit board can be comparatively intensive, and greater functionality is placed on the printed circuit board (PCB) of same area.
Yet generally existing fuse manufacture method sees also shown in Figure 1ly, is the generalized section of existing fuse.It uses hot blast, flame to carry out scolding tin; described tin point tin liquor surface 100 natures are to lower recess; make its directly joining fuse 200 and the manufacture that is connected pin 300, must be in the end sheathed two copper caps 400,500, repeatedly weldering is melted in tin sticky; there is not the good location design again; make it form unsettled protective effect, so its product stability is not good, it is high again to make difficult cost; use the waste material and the energy, produce the disqualification rate height.
Again; general electronic circuit is the one side that part is placed in circuit board; and the fuse pin is welded on the another side; the solder joint operation of this kind processing pin; allow described fuse pin and smelting part; small peeling off takes place easily; because outward appearance is normal; be not easy to check out the small of inner smelting part and pin to peel off, cause secondary melting welding, so allow and pass through greater than the maximum electric current that uses of normal rating and produce localized hyperthermia; make it can not determine the maximum electric current that uses of normal rating; and make expensive device impaired; burn; injury or peril etc. are so protection not exclusively can not be satisfied the demand on the market.
Therefore prior art summary has following shortcoming
1. fuse of the prior art uses hot blast, flame to carry out scolding tin, and described tin point tin liquor surface nature makes its directly joining fuse and the manufacture that is connected pin to lower recess.
2. fuse of the prior art when the solder joint operation of processing pin, is easy to generate localized hyperthermia and causes secondary melting welding, and protection not exclusively can not be satisfied the demand on the market.
3. fuse of the prior art, sheathed two copper caps in the end, repeatedly weldering is melted in tin sticky, and electrical impedance increases, and it is high again to make difficult cost, uses the waste material and the energy, produces the disqualification rate height.
4. fuse of the prior art be can not determine the maximum electric current that uses of normal rating during use, protective circuit safety, and make expensive device impaired, burn, injury or peril.
In view of this, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case inventor institute desire solution.So, this case inventor is based on the experience of being engaged in the Related product design for many years, inconvenience thoughts on above-mentioned traditional articles for use, take great pains to attain one's goal through for many years and to concentrate on studies, study improvement, finally the many shortcomings of existing fuse of can forgoing are are successfully researched and developed and are finished this case, and the present invention is born, and to promote effect.
Summary of the invention
