Description
Technical field
The utility model relates to a kind of Protector for electric appliances, and more particularly, it relates to a kind of fuse.
Background technology
Fuse switch is by guide hook, dynamic/static contact, cartridge fuse three part compositions, dynamic/static contact comprises moving contact and fixed contact, fixed contact is arranged on guide hook two ends, cartridge fuse is made up of the expulsion tube of internal layer and outer field phenolic aldehyde paper tube or epoxy glass fiber cloth pipe, fuse is after fusing, cartridge fuse does circumferential movement taking lower moving contact as fulcrum under the Action of Gravity Field of self, cartridge fuse and baffle plate collide, cartridge fuse impulsive force is excessive, constantly bounce-back, equipment easily damages, fuse is after fusing, it is fuse disruption that technical staff can not judge in the very first time, cause unnecessary puzzlement to maintenance.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of fuse, has warning function, the feature that long service life and the scope of application are wide.
For achieving the above object, the utility model provides following technical scheme:
A kind of fuse, comprise guide hook, dynamic/static contact and cartridge fuse, between described guide hook and cartridge fuse, be provided with alarm mechanism, described alarm mechanism comprises connector and housing, in described housing, be provided with sound contact, elastic component, binding post and alarm, described quiet contact for move contact and contact, described elastic component supports and is located between shell bottom wall and moving contact, described alarm is electrically connected by binding post with sound contact, described connector one end is connected with one end of moving contact relative resilient part, the other end extends to the outside of housing and is detachably fixedly connected with cartridge fuse from shell bottom wall direction, the other end of the relative connector of described housing is connected with guide hook.
By adopting technique scheme, fuse is after fusing, cartridge fuse drops under the Action of Gravity Field of self and following fixed contact is that fulcrum does circumferential movement, cartridge fuse is under the effect of connector and housing and locate, connector is straightened, on the one hand, while preventing that cartridge fuse from cushioning downwards, lower moving contact and baffle plate constantly collide, reduce useful life, on the other hand, connector is straightened, moving contact under tension contacts with quiet contact and forms electric power loop, alarm equipment alarm, fuse is not when by fusing, moving contact separates in quiet contact under the effect of elastic component, alarm connect circuit go out disconnect state.
The utility model is further set to: described moving contact and quiet contact are all set to suitable wedge type block.
By adopting technique scheme, moving contact and quiet contact are set to suitable wedge type block, and simple shape is easy to assembly, and stable connection contacts effectively, avoids occurring the phenomenon of loose contact.
The utility model is further set to: described elastic component is set to spring.
By adopting technique scheme, spring cost is low, easy to assembly.
Brief description of the drawings

Embodiment
Referring to figs. 1 through Fig. 2, the utility model fuse embodiment is described further.
A kind of fuse, comprise guide hook 1, dynamic/static contact 2 and cartridge fuse 3, between described guide hook 1 and cartridge fuse 3, be provided with alarm mechanism 4, described alarm mechanism 4 comprises connector 41 and housing 42, in described housing 42, be provided with sound contact 422, elastic component, binding post 424 and alarm 425, described quiet contact 422 is for contacting with moving contact 421, described elastic component supports and is located between housing 42 diapires and moving contact 421, described alarm 425 is electrically connected by binding post 424 with sound contact 422, described connector 41 one end are connected with one end of moving contact 421 relative resilient parts, the other end extends to the outside of housing 42 and is detachably fixedly connected with cartridge fuse 3 from housing 42 diapire directions, the other end of described housing 42 relative connectors 41 is connected with guide hook 1.
By adopting technique scheme, fuse is after fusing, cartridge fuse 3 drops under the Action of Gravity Field of self and following fixed contact 22 does circumferential movement for fulcrum, cartridge fuse 3 is under the effect of connector 41 and housing 42 and locate, connector 41 is straightened, on the one hand, while preventing that cartridge fuse 3 from cushioning downwards, lower moving contact 21 and baffle plate constantly collide, reduce useful life, on the other hand, connector 41 is straightened, moving contact 421 under tensions contact with quiet contact 422 and form electric power loop, alarm 425 is reported to the police, fuse is not when by fusing, moving contact 421 separates in quiet contact 422 under the effect of elastic component, the circuit that alarm 425 connects go out disconnect state (connector 41 is set to hawser, the pliability of hawser is high, cost is low, easy to assembly, housing 42 is connected between cartridge fuse 3 and guide hook 1 by hawser).
Described moving contact 421 is all set to suitable wedge type block with quiet contact 422.
By adopting technique scheme, moving contact 421 is set to suitable wedge type block with quiet contact 422, and simple shape is easy to assembly, and stable connection contacts effectively, avoids occurring the phenomenon of loose contact.
Described elastic component is set to spring 423.
By adopting technique scheme, spring 423 costs are low, easy to assembly (elastic component can be set to shell fragment and block rubber, for convenient for assembly, and preferential torsional spring 423).
The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
