Description
Technical field
The invention belongs to circuit protection and use the fuse field, disconnected slowly surface mounting fuse protector of particularly a kind of novel high-power and manufacture craft thereof.
Background technology
Current, the route protection element is applied in increasing circuit board, and wherein overflow protecting element can effectively reduce the damage of overcurrent to element device and user, and one of element that this overcurrent protection function is provided is a surface mounting fuse protector.Because of surface mounting fuse protector can adopt identical packaging technology to be assembled on the circuit board with elements such as plate resistor, electric capacity, inductance, so its application spreads all over communication apparatus, computer, audio-visual equipment and supply convertor etc.Along with the progressively expansion of application, the series of surface mounting fuse protector is divided also initial fast disconnected type, disconnected type derives types such as anti-high surge, big electric current slowly.But surface mounting fuse protector is limited by the size of himself and the strength of materials, the difficult disconnected slowly type fuse products of producing high-power high rated current.
A kind of method of making fuse on FR4 epoxy resin substrate is provided among the Chinese invention patent ZL95193295.0 " surface-mounted fuse device ", the method can be made the fuse of small size (EIA0603 and EIA0402 etc.), low cold-state resistance, but its linear fuse fuses under the condition of overload current comparatively fast, can't realize fusing at a slow speed.
Provide a kind of snakelike fuse-wires structure among the Chinese invention patent ZL97196373.8 " surface mounting fuse protector and manufacture method thereof ", this structure can effectively improve the area of dissipation of fuse, the heat that makes fuse produce when overload can in time distribute towards periphery, and then can bear bigger pulse shock under the high overload condition.But the method can only be made fuse at substrate surface, and can't make the multilayer fuse-wires structure, makes the rated current of fuse be very limited, and can't make the disconnected slowly type surface mounting fuse protector that EIA0603 size rated current surpasses 5A at present with the method; Simultaneously, because of fuse can only be produced on substrate surface, the arc extinction performance of fuse failure its surrounding medium of moment is relatively poor, and there is certain potential safety hazard in the arcing that flashes.
A kind of multilayer tablet fuse is disclosed among the China utility model patent ZL200820217547.7; it comprises ceramic substrate, back electrode, face electrode, fuse; protective layer and metal termination; wherein fuse is a multilayer; the adjacent layer fuse is end to end successively; the two ends of fuse of joining is joined matcoveredn on every layer of fuse with the face electrode of substrate both sides respectively.The fuse of this structure is to adopt the fuse that printing one deck is connected with the face electrode on ceramic substrate; on electrode, print protective layer then; on protective layer, print fuse again; so alternately printing; realize that the adjacent layer fuse joins end to end, two terminations of the fuse that links to each other are connected with the face electrode of substrate both sides respectively.This structure can realize the cascaded structure of multilayer fuse, and advantage is the area of dissipation that effectively raises fuse, can realize the characteristic that fuse fuses at a slow speed; Shortcoming is the fuse-wires structure complex process of alternative expression, and every layer of fuse all needs just can finish through super-dry, sintering process.Simultaneously, because of adjacent layer fuse therebetween matcoveredn, protective layer make and sintering after consistency will be to upper strata fuse-wires structure and adjacent fuse be connected the generation considerable influence.Though this method can realize the multilayer fuse-wires structure, its complex process, the difficult disconnected slowly type fuse of realizing high-power high rated current, low cold-state resistance.
