Description
Technical field
This utility model relates to electric prospection accessory, particularly to a kind of electric fuse with explosion-proof heat sinking function.
Background technology
Electric fuse, also known as fuse, fuse, a kind of is connected on electronic circuit the disposable assembly in order to protection circuit,
When circuit powers on and flows through big so that it is in metal wire or sheet metal produce high temperature and fuse, cause open circuit and interruptive current, with
Protect a circuit from coming to harm.Need the electric fuse manually more renewed so that circuit resumes operation after old blown fuse.
In the past because produced high temperature cause existing fuse structure for electronics to be protected by the big electric current of electronic circuit
Circuit does not comes to harm, it is therefore necessary to be blown, but then need manually be replaced with new electric fuse after fusing and electronics could be allowed to fill
Putting continuation properly functioning, therefore money and human cost all can improve.Existing electric fuse is because heat insulation structural designing technique is owed
Good, cause electric fuse usually because be created in electronic circuit high temperature impact and it occur frequently that fusing situation.
Furthermore, general existing electric fuse causes electric fuse to fuse because of the high temperature that overcurrent is inducted, and while fusing
Making the internal metal ion gas producing electric fuse of hollow cylindrical body, this metal ion easily makes hollow cylindrical body internal generation electricity
Arc, and the generation of electric arc easily makes described hollow cylindrical body rupture.
Utility model content
