As melt, the electric appliance of disjunction circuit, is series in circuit, and when overloading or short circuit current flow passes through melt, melt itself will be sent out
Heat and fuse, so as to all play certain protective effect to electric system, various electrical equipments and household electrical appliance.With anti-
Delay character, when overload current is small, fusing time length；When overload current is big, fusing time is short.Therefore, in certain overload electricity
Recover normal to electric current in the range of stream, fuse will not fuse, and can be continuing with.Fuse is mainly by melt, shell and branch
Seat three parts composition, wherein melt are the key elements for controlling operating chacteristics.
Much narrow neck is all that single, internal installation is also relatively simple to existing fuse, causes the proof voltage of fuse
Ability is general, is also easy to produce electric arc, and there are some potential safety problems.
Utility model content
The purpose of this utility model is that the defects of being directed to the prior art and deficiency, there is provided a kind of simple in structure, design is closed
Reason, surface mounting fuse protector easy to use, it by being designed to narrow neck shape on sheet metal, and take multiple narrow necks into
Row serial or parallel connection or series-parallel structure design, so that the proof voltage ability of the surface fuse of the invention is carried
Rise.And its bending design can effectively prevent the inner wall of close ceramics square tube through hole at narrow neck on sheet metal, so that molten
The consistency of performance of disconnected device is preferable.
To achieve the above object, the technical solution adopted in the utility model is：It includes ceramic square tube, solder, two ends
Electrode, sheet metal, arc quenching material；The interior electrode that two end faces of the ceramics square tube have, and carry through hole, the sheet metal
It is upper to carry at bending part and narrow neck, and be positioned in through hole, two termination electrodes pass through solder and interior electrode, sheet metal weld
Integrally formed electrical connection is connect, arc quenching material is filled in through hole, and wraps up the part metals piece positioned at through hole.
Preferably, the sheet metal has at least one narrow neck portion or narrow neck to be replaced by wire.
Preferably, there is low-melting alloy at the narrow neck of the sheet metal, the quantity of narrow neck can be odd number, can also
It is even numbers.
Preferably, the material of the sheet metal or wire can be gold or silver or copper or alloy.
Formed preferably, the arc quenching material can mix solidify afterwards by solid arc quenching material with liquid arc quenching material.
With the above structure, a kind of surface mounting fuse protector described in the utility model has the advantages that：
1. its narrow neck may be designed to multiple, narrow neck can be series connection or in parallel or connection in series-parallel is combined,
So that the proof voltage ability of fuse is greatly improved, and the use of arc quenching material, can be to avoid the generation of electric arc.
2. the bending part on its sheet metal can ensure that sheet metal is in ceramic square tube through hole centre position, effectively prevent
Close to the inner wall of ceramics square tube through hole at narrow neck on sheet metal, so that the consistency of performance of fuse is preferable.
