Description
Technical field
The present invention provides a kind of mini-insurance yarn production method and finished product, relates in particular to finished electrode portion, and the one of which end is set as two ring bodies of closed-end, and is provided with the solid face that holds; In addition its manufacturing approach comprises: the position on its electrode part plane, form the open-work groove end that the end links to each other, and make the melting welding can be more effectively firm.
Background technology
The traditional insurance silk generally is used for electronic product, via through fuse pass through electric current excessive, danger such as thermal ignition took place in order to avoid circuit in smelting part thereby fusing, purpose is protecting people and equipment not to damage because of overcurrent, even breaking out of fire.
Moreover along with electric equipment is compact, function becomes increasingly complex at present, and the part that needs is more and more; Circuit and electronic component on the circuit board are also more and more intensive, so the circuit of circuit substrate trends towards miniaturization, electronic component is microminiaturized; Be the normality method for using, 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 general mini-insurance yarn production method uses the direct joining of scolding tin to connect pin and the manufacture that melts white silk portion; Do not have the good location design again, make it form unsettled protective effect, so its product stability is not good; Make difficulty, cost is high again, uses waste material and produce fraction defective high.
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 lets and between this microfuze pin and the molten white silk portion 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 let and pass through greater than the maximum electric current that uses of normal rating and produce localized hyperthermia; Make it be not sure of the maximum electric current that uses of normal rating; And make expensive device impaired, burn, injury or peril etc., so protection not exclusively, can not be satisfied the demand on the market.
Therefore prior art summary has following shortcoming:
1, the microfuze of prior art, no good location design, the product stability is not good, and it is high again to make difficult cost, uses waste material and produce fraction defective high.
2, the microfuze of 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, the microfuze of prior art is not sure of the maximum electric current that uses of normal rating during use, protective circuit safety, and make expensive device impaired, burn, injury or peril.
4, prior art when small peeling off taken place, because outward appearance is normal, has the problem that is not easy to check out inner disappearance.
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, and thoughts on the inconvenience of above-mentioned traditional articles for use, warp is taken great pains to attain one's goal for many years and concentrated on studies; Study improvement; Finally the many shortcomings of commonly using microfuze of can forgoing are are successfully researched and developed completion this case, make the present invention be able to be born, and to promote effect.
Summary of the invention
The objective of the invention is to: a kind of microfuze and manufacturing approach thereof are provided,, make melting welding can be more effectively firm to overcome the shortcoming of above-mentioned prior art.When its smelting part end and two electrode part melting welding, tin liquor can wrong not invaded smelting part, or rotates because of two electrode part slippages when using and influence smelting part, causes the danger that ensures electric current mistake standard, and makes microfuze have high yield, high-quality, high security.
For realizing the purpose of foregoing invention, the technical scheme that the present invention adopted is: a kind of microfuze is provided, and it comprises:
