Described fusable links is two or many winding-type fusable links that wire rod is formed.
Described fusable links is a wall scroll wire or sheet metal fusable links.
Said location division is to be directly molded on the copper cap, and it is the annular protrusion that on copper cap bottom surface, forms a direction extension in insulated tube, and then copper cap center just forms the recess of location, a confession fusable links end.
Said location division is on the straight forming copper cap, and it is to form the projection of a direction extension in insulated tube at middle part, copper cap bottom surface, and just forms the short slot of ccontaining scolding tin and location fusable links between projection and the copper cap sidewall; And fusable links is obliquely to be cornerwise and to be placed in the insulated tube.
Said location division is one to have the abaculus of centre bore, and scolding tin is provided in a side of in this centre bore, and the end of fusable links is to stretch to place this centre bore.
Described location division is a stopper, and plug is at the two ends of insulated tube, and the fixing end of fusable links of extruding makes that fusable links is oblique to be cornerwise and to be placed in the insulated tube.
After adopting said structure; Through in the copper cap at two ends, setting up a location division; Fusable links in the insulated tube is positioned in the location division, thereby guarantees fully the contacting of scolding tin and fusable links on the copper cap, under the situation that soldering tin amount does not increase; Can greatly avoid the situation of rosin joint or dry joint to take place, improve the rate of finished products of fuse.

Embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Like Fig. 2, be first embodiment of the utility model, it comprises insulated tube 1, fusable links 2, copper cap 3 and is located at the scolding tin 4 on copper cap 3 bottom interior wall, winding-type fusable links 2.Need to prove that in the embodiment that this paper lifted, the structure that fusable links adopted is to be one to be wound with winding-type fusable links wiry, certainly, fusable links also can adopt wall scroll wire or sheet metal structure.
Wherein, Mount fusable links 2 in the insulated tube 1 of open at both ends; And two bronze medal caps 3 are fixed in the two ends of insulated tube 1, the scolding tin 4 on two end in contact copper caps, the 3 bottom surface inwalls of fusable links 2, thus be fixed on the copper cap 3 after making scolding tin 4 fusions be coated on the end of fusable links 2 through heating copper cap 3.
The improvements of the utility model are, are provided with a location division in the bottom of two bronze medal caps 3.In the present embodiment, the location division is to be directly molded on the copper cap 3, and it is the annular protrusion 31 that on copper cap 3 bottom surfaces, forms a direction extension in insulated tube 1, and then copper cap 3 centers just form the recess 311 of location, confession fusable links 2 ends.Fusable links 2 just can be positioned in the recess 311 in being placed on insulated tube 1 time, and 4 in scolding tin is located in the recess 311; Through heating copper cap, thereby scolding tin 4 fusions are coated on the end of fusable links 2, thereby fusable links 2 just can fully contact with scolding tin 4; Under the situation that soldering tin amount does not increase; Just can avoid the situation of rosin joint or dry joint to take place, fusable links 2 uprightly mounts the insulated tube middle part, has also guaranteed the heat radiation consistency that fusable links is good.
Like Fig. 3; Second embodiment for the utility model; The place that present embodiment is different from first embodiment is the location division in the fuse, and the location division is on the straight forming copper cap 3 in the present embodiment, and it is the projection 32 that forms a direction extension in insulated tube at middle part, copper cap 3 bottom surfaces; And just form the short slot 321 of ccontaining scolding tin 4 and location fusable links between projection 32 and copper cap 3 sidewalls, and fusable links 2 is obliquely to be cornerwise and to be placed in the insulated tube.Fusable links 2 is provided with scolding tin 4 in the short slot 321 when being placed on insulated tube 1 inside, thereby 3 back scolding tin 4 fusions of heating copper cap are coated on the end of fusable links 2, thereby just can guarantee that fusable links fully contacts with scolding tin.
Like Fig. 4; Be the 3rd embodiment of the utility model, the location division in the present embodiment for be provided with in copper cap 3 bottoms one have a centre bore 331 abaculus 33, this abaculus 33 is fixed in copper cap bottom; And be fixed in the insulated tube 1; And scolding tin 4 is provided in a side of in this centre bore 331, and the end of fusable links 2 is to stretch to place this centre bore 331, so the internal diameter of this centre bore is grown up in the insertion for fusable links 2 of the external diameter of fusable links 2.After establishing a certain amount of scolding tin 4 in the copper cap 3, heating copper cap 3, thus scolding tin 4 fusions are coated on the end of fusable links 2, thus can guarantee that fusable links 2 fully contacts with scolding tin 4, avoided the situation of rosin joint or dry joint to take place.
Like Fig. 5; Be the 4th embodiment of the utility model, the location division in the present embodiment is for being provided with a stopper 34 in copper cap 3 bottoms, and stopper 34 plugs are at the two ends of insulated tube 1; The fixing end of fusable links of extruding makes that fusable links 2 is oblique to be cornerwise and to be placed in the insulated tube 1.After in copper cap 3, establishing a certain amount of scolding tin 4, heating copper cap 3, thus scolding tin 4 fusions are coated on the end of fusable links 2, thus can guarantee that fusable links 2 fully contacts with scolding tin 4, avoided the situation of rosin joint or dry joint to take place.
Certainly; Also can on the copper cap, adopt other forms of location structure with the location fusable links in the utility model on the fuse; Product form of the foregoing description and graphic and non-limiting the utility model and style; The those of ordinary skill of technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing under any.
