Abstract
The utility model aims to provide a novel fusible core of a fuse, which has the advantages of simple structure, convenient processing and low material cost. To achieve the purpose, the utility model adopts the technical scheme that the fusible core of the fuse is positioned through the abutting joint of the buckle of a connecting plate and the groove of a contact knife, and fusant is well welded on the surface of the end part of the contact knife.
Description
Technical field
The utility model relates to the electrical device field, is specifically related to a kind of fuse-link fusible core that protection device is used.
Background technology
At present, the fuse-link fusible core of domestic use is installed complicated, high material consumption, cost height.
Summary of the invention
It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, the novel fuse-link fusible core mounting means that the cost of material is low.
In order to achieve the above object, the technical solution adopted in the utility model is:
Is furnished with connecting plate on the described fuse fusible core, with the matching relationship employing interference fits of contact knife groove, to guarantee the welding location.Described fuse fusible core is for directly to weld melt at the contact knife cross cut end (of a beam).
Compared with prior art, advantage of the present utility model is as follows:
1, prior art is for to weld melt on the contact knife connecting plate, and connecting plate and contact knife cutter hub need welding, and the contact knife connecting plate must adopt copper material, cost height, complex technical process.And the utility model mounting process is simple, and contact knife does not need to weld the contact knife connecting plate, directly welds melt at the contact knife cross cut end (of a beam).
2, the utility model is simple in structure, and is easy to process.

6 are among the figure---the melt that prior art and the utility model are general.
7 are among the figure---the spot welding point between the utility model contact knife and the melt.
Embodiment
Referring to Fig. 1, the protection device of domestic present use fuse-link fusible core adds man-hour, needs contact knife connecting plate and the welding of contact knife cutter hub, and with melt and connecting plate welding, this process complexity is taken material, cost height then.
Referring to Fig. 2, Fig. 3, Fig. 4, a kind of protector fuse-link fusible core described in the utility model is to adopt interference fits to cooperate between contact knife connecting plate and the contact knife groove, guarantees the welding location; Melt is welded directly at the contact knife cross cut end (of a beam).
Claims (2)
1. fuse fusible core, it is characterized in that: described fuse fusible core is for directly to weld melt at the contact knife cross cut end (of a beam).
2. according to claim 1 fuse-link fusible core, it is characterized in that: be furnished with connecting plate on the described fuse fusible core, with the matching relationship employing interference fits of contact knife groove, to guarantee the welding location.
