Description
Technical field
The utility model relates to technical field of electric appliances, specifically relates to fuse.
background technology
Fuse comprises the fuse of overcoat and overcoat inside; overcoat is generally columniform porcelain body; in the middle of overcoat, have hollow, fuse is just arranged on hollow inside, and overcoat two ends are installation connecting element also; when there is transient high voltage; the fuse of fuse breaks, and plays the object of protective device, when fuse opening, can produce spark; be accompanied by spark, also can produce many metallic particles.
In prior art, fuse does not have housing around, the metallic particles of its generation is just attached on the wall of hollow, the fuse of a fuse occurs, after fusing several times, just to have many metallic particles on the wall of its overcoat hollow, will increase like this conductivity of overcoat, reduce its creepage distance, affect the result of use of fuse, even need the fuse that more renews, increased use cost.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provide a kind of reduce do not affect next result of use after overcoat hollow wall attached metallic particles, fuse failure, reduce use cost fuse---fuse has the fuse of housing.
The technical solution of the utility model is achieved in that fuse has the fuse of housing, comprise fuse, fuse comprises again protective tube, and protective tube comprises again the fuse of overcoat and overcoat inside, and overcoat is the porcelain body of cylinder, in the middle of overcoat, there is hollow, fuse is just arranged on hollow inside, and overcoat two ends are installation connecting element also, it is characterized in that: described fuse outside is also socketed with columnar housing, shielding shroud fuse, and described housing is that insulating material is made.
Say further, described housing two ends also have bulkhead, and described bulkhead is that linchpin has fuse hole in structure, the centre of housing inside, and bulkhead and housing are fixed together, and fuse hole adds is holding fuse.
The beneficial effects of the utility model are: such fuse does not affect next result of use after having advantages of the overcoat of minimizing hollow wall attached metallic particles, fuse failure, reduced use cost; Described housing two ends also have bulkhead, described bulkhead is that linchpin has fuse hole in structure, the centre of housing inside, bulkhead and housing are fixed together, fuse hole adds is holding fuse, and the metallic particles with fuse generation can not run out of from the two ends of housing, the better advantage of result of use.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model fuse has the fuse of housing.
Fig. 2 is the part section structural representation of protective tube.
Wherein: 1, fuse 2, protective tube 21, overcoat 22, fuse 3, hollow 4, housing 5, bulkhead.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, fuse has the fuse of housing, comprises fuse 1, and fuse comprises again protective tube 2, protective tube comprises again the fuse 22 of overcoat 21 and overcoat inside, overcoat is the porcelain body of cylinder, in the middle of overcoat, has hollow 3, and fuse is just arranged on hollow inside, overcoat two ends are installation connecting element also, it is characterized in that: described fuse outside is also socketed with columnar housing 4, shielding shroud fuse, and described housing is that insulating material is made.
Like this, the metallic particles producing during fuse failure can be deposited in housing inside, and do not after-tack, is not connected on porcelain body inside, and housing can be changed easily, and cost is lower, has effect of the present utility model.Housing is socketed in fuse outside, because there is connector at two ends, is keeping off, and housing can not come off.
Say further, described housing two ends also have bulkhead 5, and described bulkhead is that linchpin has fuse hole in structure, the centre of housing inside, and bulkhead and housing are fixed together, and fuse hole adds is holding fuse.Metallic particles just can not run out of from the exit portion at housing two ends like this, better effects if.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed in the scope of the claims of the present utility model.
Claims (2)
1. fuse has the fuse of housing, comprise fuse, fuse comprises again protective tube, and protective tube comprises again the fuse of overcoat and overcoat inside, and overcoat is the porcelain body of cylinder, in the middle of overcoat, there is hollow, fuse is just arranged on hollow inside, and overcoat two ends are installation connecting element also, it is characterized in that: described fuse outside is also socketed with columnar housing, shielding shroud fuse, and described housing is that insulating material is made.
2. fuse according to claim 1, is characterized in that: described housing two ends also have bulkhead, and described bulkhead is that linchpin has fuse hole in structure, the centre of housing inside, and bulkhead and housing are fixed together, and fuse hole adds is holding fuse.
