Description
Technical field
This utility model relates to electric fuse technical field, is specially a kind of tubular glass electric fuse.
Background technology
When circuit malfunctions or exception, constantly raise along with electric current, and the electric current raised likely damages electricity
Some important devices in road or valuable device, it is also possible to burn circuit and even cause fire.If circuit correctly disposes
Electric fuse, then, electric fuse will be current anomaly be increased to certain height and temperature when, and electricity is cut off in self fusing
Stream, thus play the effect of protection circuit safe operation, general insurance silk is made up of three parts: one is melt portion, and it is
The core of electric fuse, plays the effect cutting off electric current, same class, the melt of same specification electric fuse during fusing, material is identical,
Physical dimension is identical, resistance value is the least and it is consistent, it is most important that operating chacteristics wants consistent, and domestic electric fuse is normal
Make with lead-antimony alloy；Two is electrode part, generally has two, and it is the vitals that melt couples with circuit, and it must have
Good electric conductivity, should not produce and significantly install contact resistance；Three is holder part, and the melt of electric fuse is the most very thin the most soft
Soft, the entirety that melt was fixed and made three parts and becomes rigidity by the effect of support exactly is easily installed, uses, and it must have
Good mechanical strength, insulating properties, thermostability and anti-flammability, the most should not produce fracture, deform, burn and short circuit etc. is existing
As, but the most a lot of electric fuses is all box-packed structure, using installation when, it will usually take bigger space,
And structural stability is the highest, causes circuit can not bear high-power use, and many times can cause melting because of high temperature
Fracture of wire is impaired, therefore devises a kind of tubular glass electric fuse.
Utility model content
For problem above, this utility model provides a kind of tubular glass electric fuse, is arranged by the structure of glass tubing,
The structural stability of electric fuse can be greatly improved so that fuse structure is smaller and more exquisite, can easily be arranged in electronic circuit,
During assembling, there is bigger space, it is simple to operation, be worthy to be popularized.
For achieving the above object, this utility model provides following technical scheme: a kind of tubular glass electric fuse, it includes glass
Glass body and fuse holder, described fuse holder is arranged in canals of stilling, and described fuse holder is provided with installation screw, institute
Stating and be provided with pad between installation screw and fuse holder, described fuse holder connects electric pole plate and lower electrode plate, described
Being provided with memory wire on electric pole plate and lower electrode plate, two ends, described canals of stilling left and right are provided with metal cap, described gold
Belong to cap and include cap body, described cap body is provided with perforation, in described perforation, is provided with end electrode, described medicated cap master
Fin it is provided with on body.
As a kind of preferably technical scheme of this utility model, described canals of stilling upper end is provided with insulating barrier.
As a kind of preferably technical scheme of this utility model, described canals of stilling lower end is provided with mucigel.
As a kind of preferably technical scheme of this utility model, described metal cap lower end is provided with installation rivet.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is arranged by the structure of glass tubing, can be greatly improved the structural stability of electric fuse so that insurance
Silk structure is smaller and more exquisite, can easily be arranged in electronic circuit, has bigger space during assembling, it is simple to behaviour
Make, be worthy to be popularized.
