Description
Technical field
The utility model relates to a kind of electric safety protector, relates in particular to a kind of fuse of realizing short circuit and overload protection.
Background technology
Fuse (fuse) refers to when electric current surpasses setting, with the heat producing own, makes melt fusing, a kind of electrical equipment of open circuit.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is to apply one of the most general protection device.
Fuse generally includes the insulation shell of melt and coated melt, for preventing that fuse from leaking electricity, conventionally insulation shell is set to entirely be coated melt, only the power connection end of melt stretches out insulation shell, this makes the complicated structure of insulation shell, increase on the one hand the production cost of fuse, can be unfavorable for fuse miniaturization on the other hand.
Therefore, need a kind of small volume, fuse simple in structure badly, to reduce production costs, meet application demand.
Utility model content
The purpose of this utility model is to provide a kind of small volume, fuse simple in structure, to reduce production costs, meets application demand.
To achieve these goals, the utility model discloses a kind of flat fuse, comprise melt and insulation shell, described melt and described insulation shell are all tabular, described melt be located in described in two between insulation shell and two power connection ends of described melt stretch out two described in insulation shell, described in two, between insulation shell, be filled with the arc-extinguishing medium of coated described melt.
Compared with prior art, the flat fuse that the utility model provides, melt and insulation shell are all tabular, and the melt being located between two insulation shells insulate by the arc-extinguishing medium of filling, and guarantees the insulation effect of flat fuse.Flat melt and insulation shell have been simplified the structure of flat fuse greatly, reduce production costs, and make the volume of flat fuse can be less simultaneously.
Preferably, described in one, insulation shell protrudes out formation locating convex block towards insulation shell described in another, and on described melt, correspondence offers detent; The position to insulation shell by locating convex block and detent location melt, be to fill between two insulation shells in the process of arc-extinguishing medium, melt not can by the impact of arc-extinguishing medium with push lower relative insulation shell and be subjected to displacement, make the unlikely insulation shell outside that reaches, both sides of melt, to guarantee the insulation effect of flat fuse.
Particularly, four described locating convex blocks are arranged at respectively two jiaos of positions on the diagonal of insulation shell described in two, and on insulation shell described in two described in described in two on line between locating convex block and insulation shell described in another line between locating convex block be the setting intersecting.
Particularly, described detent is the groove that runs through described melt; Detent is groove, while making to install melt, without the direction of differentiating melt, simplifies production process.
Preferably, described arc-extinguishing medium is glass paste.
Preferably, the material of described insulation shell is pottery.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
The flat fuse of the utility model as depicted in figs. 1 and 2, comprise melt 100 and insulation shell 200, melt 100 and insulation shell 200 are all tabular, and melt 100 is located between two insulation shells 200, are filled with the arc-extinguishing medium 300 of coated melt 100 between two insulation shells 200.Shown in Fig. 3 and Fig. 4, more specifically:
As shown in Figures 2 and 3, melt 100 comprises that two power connection ends 110 are structure as a whole with fusing portion 120, two power connection ends 110 and the fusing portion 120 that are connected two power connection ends 110, and the melt 100 of two power connection ends 110 and fusing portion 120 formations is positioned at a rectangular area.Insulation shell 200 is rectangular structure also, and the length of insulation shell 200 is less than the length of melt 100, the width of insulation shell 200 is greater than the width of melt 100, while making melt 100 be located between two insulation shells 200, in the gap of fusing portion 120 between two insulation shells 200, the end that deviates from fusing portion 120 of two power connection ends 110 stretches out two insulation shells 200 for connecing electricity; The width of insulation shell 200 is greater than the width of melt 100, the arc-extinguishing medium 300 that makes fusing portion 120 and power connection end 110 part between two insulation shells 200 be filled to two insulation shells 200 is coated, to guarantee the insulation effect of the flat fuse of the utility model.In being different from other embodiment of the present embodiment, melt 100 and insulation shell 200 also can be not rectangular, only need two insulation shells 200 to be coated fusing portion 120.
Further, an insulation shell 200 protrudes out and forms locating convex block 210 towards another insulation shell 200, and on melt 100, correspondence offers detent 111.Concrete, four locating convex blocks 210 are arranged at respectively two jiaos of positions on the diagonal of two insulation shells 200, and the line between two locating convex blocks 210 on an insulation shell 200 is with the line between two locating convex blocks 210 on another insulation shell 200 setting intersecting.Position by locating convex block 210 with the relative insulation shell 200 of detent 111 location melt 100, be to fill in the process of arc-extinguishing medium 300 between two insulation shells 200, melt 100 not can by the impact of arc-extinguishing medium 300 with push lower relative insulation shell 200 and be subjected to displacement, make unlikely insulation shell 200 outsides that reach, both sides of melt 100, to guarantee the insulation effect of flat fuse.Preferably, detent 111 is for running through the groove of melt 100, during assembling flat-plate fuse, without differentiate melt 100 direction, directly detent 111 is aimed to insertion with locating convex block 210.
In the present embodiment, arc-extinguishing medium 300 is glass paste, and the material of insulation shell 200 is pottery.But indefiniteness, insulation shell 200 and arc-extinguishing medium 300 can also have for other material of insulation effect.
Compared with prior art, the flat fuse that the utility model provides, melt 100 and insulation shell 200 are all tabular, and the melt 100 being located between two insulation shells 200 insulate by the arc-extinguishing medium 300 of filling, and guarantees the insulation effect of flat fuse.Flat melt 100 and insulation shell 200 have been simplified the structure of flat fuse greatly, reduce production costs, and make the volume of flat fuse can be less simultaneously.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
