Abstract
The invention discloses a method for manufacturing arc extinguishing glass for a miniature fuse. The miniature fuse comprises two connection terminals, a ceramic plate, a melt and an arc extinguishing glass layer, wherein the arc extinguishing glass layer is an arc extinguishing glass sheet made of lead boron silicate glass. The steps for manufacturing the arc extinguishing glass sheet include: coating an imprinting adhesive layer on the surface of the arc extinguishing glass sheet by means of spin coating; pressing a mould with a plurality of bumps having micro-nano diameters on the lower surface on the photosensitive adhesive layer and curing the photosensitive adhesive layer by the aid of a hot pressing method or an ultraviolet photosensitive method; removing the mould in the second step from the surface of the coated photosensitive adhesive layer; and etching the arc extinguishing glass sheet in the third step by the aid of a dry ion etching method to form a plurality of micro-nano holes on the surface of the arc extinguishing glass sheet, wherein the diameters of the micro-nano holes range from 20nm to 500nm.

Description
Technical field
The present invention relates to fuse technical field, be specifically related to a kind of arc extinguishing glass-making processes for midget fuse.
Background technology
Because electronic product is more and more to miniaturization, as the fuse of circuit protection, also to the future development of small size, thus the performance of arc quenching material is had higher requirement.In the situation that consumption reduces, arc quenching material need to provide equally even better arc extinguishing ability.The conventional material for arc extinguishing comprises quartz sand, silica gel, epoxy glue, porous glass etc.
Quartz sand is conventionally applicable to volume greatly and the product of the cavity volume of a sealing can be provided, and is generally used for tubular products; Silica gel, epoxy glue can be suitable for the product of small volume, but arc quenching effect is lower.Therefore, the invention provides a kind of arc extinguishing glass-making processes for midget fuse, insulation impedance after can realizing good arc extinguishing ability and guaranteeing higher fusing, becomes the direction that those of ordinary skills make great efforts.
Summary of the invention
The object of the invention is to provide a kind of arc extinguishing glass-making processes for midget fuse, and the arc extinguishing glass that this arc extinguishing glass-making processes obtains can be realized good arc extinguishing ability, and higher insulation impedance is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of arc extinguishing glass-making processes for midget fuse, described midget fuse is comprised of two binding posts, potsherd, melt and arc extinguishing glassy layer, described melt is positioned at potsherd surface, two binding posts are electrically connected to melt two ends respectively, arc extinguishing glassy layer is covered in described bath surface, it is characterized in that: described arc extinguishing glassy layer is an arc extinguishing sheet glass, and this arc extinguishing sheet glass is comprised of lead borosilicate glass, and this arc extinguishing glass obtains by following steps:
Step 1, described arc extinguishing glass sheet surface by spin coating apply one impression glue-line.
Step 2, the mould that lower surface is had to a salient point of some nanometer-diameters are pressed on described photosensitive layer, by pressure sintering or ultraviolet photoresist process, solidify photosensitive layer, described mould lower surface contacts with applying photosensitive layer, and the diameter of described salient point is 20～500nm, and depth-width ratio is 1: 1～10;
Step 3, mould described in step 2 is removed from applying photosensitive layer surface;
Step 4, adopt dry method ion etching process etching through the described arc extinguishing sheet glass of step 3, thereby form some micro-nano holes in this arc extinguishing glass sheet surface, the diameter of this micro-nano hole is 20～500nm; Depth-width ratio is 1: 1～10;
Residual described impression glue-line is removed in step 5, cleaning.
Related content in technique scheme is explained as follows:
1,, in such scheme, the 1-5 that is spaced apart aperture between described micro-nano hole doubly.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
The present invention can realize good arc extinguishing ability for the arc extinguishing glass-making processes acquisition arc extinguishing glass of midget fuse, and higher insulation impedance is provided; Secondly, the hole size that obtains can accurately be controlled, and be evenly distributed, and process allowance is larger, thereby has guaranteed the stability of product arc extinguishing ability.
In the moment of fusing, gasification forms metallic vapour to fuse, to surrounding, splashes, and the metallic vapour splashing in this process can form conductive channel, and conductive channel produces electric arc under the high-tension effect in two ends.The effect of porous arc extinguishing glass be the glass micropore of arc extinguishing glass surface can adsorbing metal steam, porous glass can melt after absorbing the heat of steam, wraps metallic vapour particle, blocking-up conductive channel, suppresses electric arc, avoids fuse to burn because of electric arc.
Aperture and the distribution thereof of absorption porous arc extinguishing glass are most important to arc quenching effect.Aperture is too small causes metallic vapour adsorption capacity not enough, thereby aperture is excessive, causes that glass and golden steam contact area are inadequate causes that electric arc is can not moment suppressed to be fallen.As skewness can cause arc extinguishing ability uneven, can not guarantee arc quenching effect.So it is most important for the effect of arc extinguishing to access the controlled arc extinguishing glass of pore size and distribution.
