Description
Technical field
The utility model relates to a kind of overload protection arrangement of circuit breaker, and more particularly, it relates to a kind of novel fuse-link.
Background technology
Fuse-link is used for when transshipping, and the fuse failure in it plays the effect of protective circuit.
At present; fuse-link on market comprises fusion tube and fuse; the two ends of the fusion tube be made up of insulating material such as pottery, glass are arranged with interior conductive contact respectively; fuse is interspersed in fusing; the two ends of fuse are separately fixed on interior conductive contact; arc-extinguishing medium is filled with in fusion tube; arc-extinguishing medium generally adopts fine sand; the two ends of fusion tube are also fixed with arc quenching plate; although this fuse-link can play the effect of overload protection, interior conductive contact be riveting on fusion tube, be not easy dismounting; cause this fuse-link to become disposable products, comparatively waste.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of fusion tube reusable novel fuse-link.
For achieving the above object, the utility model provides following technical scheme:
A kind of novel fuse-link, comprise fusion tube and the interior conductive contact being riveted on its two ends, also comprise two bimetal leafs be made up of thermal expansion material, two ends on described fusion tube all offer the annular grooving coaxial with it, and it is interior and inconsistent with interior conductive contact after its expanded by heating that described bimetal leaf is placed in two annular groovings respectively.
By adopting technique scheme, annular grooving is for placing bimetal leaf, bimetal leaf only just can be inconsistent with interior conductive contact after its expanded by heating, interior conductive contact is made to be extruded rear distortion, thus allow interior conductive contact easily be separated from fusion tube, and in the extruding of bimetal leaf expanded by heating, the dynamics of conductive contact is softer, namely avoids damaging fusion tube, also avoid damaging interior conductive contact, make interior conductive contact and fusion tube all can Reusability.
The utility model is set to further: all there is hard metal washer the two side of described annular grooving by industrial glue bond, described washer and leave gap between conductive contact in being assemblied on fusion tube.
By adopting technique scheme, after bimetal leaf expanded by heating, extrude washer, because, washer is made up of hard metal material, and the hardness of relative fusion tube is higher, not yielding, avoiding bimetal leaf directly to extrude fusion tube makes it break, and further ensures the useful life of fusion tube.
The utility model is set to further: described bimetal leaf is spliced into ring-type by some arc metal plates.
By adopting technique scheme, bimetal leaf is spliced to form by some arc metal plates, and on the one hand, aspect is assemblied in annular grooving, and another is convenient, increases its expansion amplitude; Be spliced into ring-type for power being uniformly dispersed, internal conductance contact is out of shape to surrounding, to be easierly separated from fusion tube.
The utility model is set to further: described bimetal leaf is spliced into ring-type by three arc metal plates.
By adopting technique scheme, after three arc metal plates can ensure expansion, the dynamics acted on interior conductive contact is uniformly dispersed, easy to assembly again.
The utility model is set to further: three arc metal plates all by industrial glue bond in annular grooving.
By adopting technique scheme, by industrial glue bond, three arc metal plates are bonded in annular grooving, arc metal plate has been avoided when assembling.

Embodiment
Referring to figs. 1 through Fig. 4, novel fuse-link embodiment is described further.
A kind of novel fuse-link, comprise fusion tube 1 and the interior conductive contact 2 being riveted on its two ends, also comprise two bimetal leafs 3 be made up of thermal expansion material, two ends on described fusion tube 1 all offer the annular grooving 11 coaxial with it, it is interior and inconsistent with interior conductive contact 2 after its expanded by heating that described bimetal leaf 3 is placed in two annular groovings 11 respectively, and bimetal leaf 3 has the gap (preferential 0.1 millimeter) of 0.1 ~ 0.3 millimeter when initial condition and between interior conductive contact 2.Annular grooving 11 is for placing bimetal leaf 3, bimetal leaf 3 only just can be inconsistent with interior conductive contact 2 after its expanded by heating, interior conductive contact 2 is made to be extruded rear distortion, thus allow interior conductive contact 2 easily be separated from fusion tube 1, and the dynamics of conductive contact 2 is softer in the extruding of bimetal leaf 3 expanded by heating, namely avoid damaging fusion tube 1, also avoid damaging interior conductive contact 2, make interior conductive contact 2 and fusion tube 1 all can Reusability.
All there is the hard metal washer 4 such as aluminium alloy, stainless steel the two side of described annular grooving 11 by industrial glue bond, described washer 4 and leave gap between conductive contact 2 in being assemblied on fusion tube 1.Extrude washer 4 after bimetal leaf 3 expanded by heating, because washer 4 is made up of hard metal material, and the hardness of relative fusion tube 1 is higher, not yielding, avoid bimetal leaf 3 directly to extrude fusion tube 1 and make it break, further ensure the useful life of fusion tube 1.
Described bimetal leaf 3 is spliced into ring-type by some arc metal plates 31.Bimetal leaf 3 is spliced to form by some arc metal plates 31, and on the one hand, aspect is assemblied in annular grooving 11, and another is convenient, increases its expansion amplitude; Be spliced into ring-type for power being uniformly dispersed, internal conductance contact is out of shape to surrounding, to be easierly separated from fusion tube 1.
Described bimetal leaf 3 is spliced into ring-type by three arc metal plates 31.After three arc metal plates 31 can ensure expansion, the dynamics acted on interior conductive contact 2 is uniformly dispersed, easy to assembly again.
Three arc metal plates 31 all by industrial glue bond in annular grooving 11.By industrial glue bond, three arc metal plates 31 are bonded in annular grooving 11, arc metal plate 31 has been avoided when assembling.
A, first by catch 4 with industrial glue bond on the phase sidewall of annular grooving 11;
B, splice ringwise bimetal leaf 3 by industrial glue bond in annular grooving 11 by three arc metal plates 31, and conflict in two catch 4;
C, interior conductive contact 2 to be riveted on fusion tube 1.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged 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, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
