Description

Fuse

Technical field

The present invention is relevant for a kind of fuse, refers to that especially a kind of arc phenomenon of avoiding produces, and the structure that can conduct electricity really of its electrode.

Background technology

Existing fuse, it has a upper strata, two electrodes, a fuse, a lower floor, and each electrode has top flat body, lateral piece and the egative film body that links with electric welding.Upper strata and lower floor are superimposed with each other, and two electrodes are located at the opposite end of lower floor respectively, and fuse is electrically connected two electrodes, and fuse clip is located between upper strata and the lower floor.

Aforesaid existing fuse structure, it has following shortcoming:

One, is solid because of upper strata and lower floor,, causes the danger in the use when fusing so fuse can't thoroughly break off, and can produce arc phenomenon.

Two, top flat body, lateral piece are connected the three with the egative film body by welding, so the three when using, is prone to produce the situation of fracture, and makes electrode produce the state of loose contact, and inconvenience place in the use are arranged.

Summary of the invention

Because above-mentioned shortcoming the object of the present invention is to provide a kind of fuse, it can avoid arc phenomenon to produce, and its electrode is integrally formed, so when using, can avoid the situation of loose contact to produce.

The present invention provides a kind of fuse, and it has: a disconnecting apparatus, and it has two two electrodes and a fusing portion, and the two ends of this fusing portion are electrically connected this two two electrodes respectively; One first housing, one of which mask have one first storage tank; And one second housing, one of which mask have one second storage tank; Wherein, This disconnecting apparatus is located between this first housing and this second housing that mutually combines, and this first storage tank combines with this second storage tank, and constitutes an accommodation chamber to form; These two two electrodes lay respectively at the two ends of this second housing, and this fusing portion is arranged in this accommodation chamber.

As stated, the present invention can reach following effect:

One, accommodation chamber can make fusing portion break off fully, produces the fail safe when guaranteeing to use to avoid arc phenomenon.

Two, when making electrode, use welding processing procedure, and electrode bends with single lamellar body and is shaped, so when using, can not produce the situation of fracture or loose contact.
