Description
Technical field
This utility model belongs to emergency protective device technical field, relates to a kind of explosion-proof fuse of chip.
Background technology
The common structure of surface-adhered type protector mainly has two kinds of forms; Chinese patent 201120320869.6 provides one of which typical structure; this protector is arranged on unsettled for thread fuse-link in tubular shell, and body two ends are with end cap sealed tube body and provide the electrical connection with inner melt and the function of surface soldered.The typically conventional pottery of this kind of body material or glass are made; its mechanical strength is higher; and toughness is not enough; if protector works at higher voltages; when when overcurrent occurs, protector disconnects, protector disconnects the electric arc produced and easily causes blowing or damaged of its body, causes the protector can not safe action; can explode and cause personal injury time serious, and body is difficult to accomplish ultrathin type.Another kind of typical structure is as shown in Chinese patent 200680043689.X, and fuse-link is molded on one piece of substrate surface by it, a more additional protective layer covers fuse-link, then forms two terminations at the two ends of protector to draw fuse-link and to carry out surface soldered.This kind of protector substrate used thereof material is often pottery or PCB material; and protective layer material is often resin or low temperature glass; the Surge handling capability of this structure electric fuse is typically poor than the structure with tinsel as fuse-link; and fuse-link is close to protective layer; after protector size is little to a certain extent, disjunction under higher running voltage, the electric arc that fuse-link produces will also result in protective layer or substrate breakage; damage product, explosion energy even jeopardizes personal safety.
Therefore, when designing miniature surface-adhered type protector, in order to ensure the ability of its safe disjunction, the most effectively arc extinguishing has just become the focus being primarily upon.The different structure of corresponding protector; its arc quenching method is mainly fills arc quenching material in protector tube body and prints arc extinguishing coating two kinds on fuse-link; its mechanism of action is that arc quenching material is coated with fuse-link; the electric arc produced during disjunction can be extinguished by arc quenching material, thus improves the breaking capacity of protector.But for common ceramic base surface-adhered type protector, its arc extinguishing layer is the most excessively poor with the adhesion of ceramic substrate, product can be caused when overcurrent disconnects, metallic vapour sprays between arc quenching material and substrate, causes accident to occur, and explosion-proof capabilities is difficult to promote.
