Abstract
The utility model provides an arc extinguishing fusible core, including two contact pieces be provided with thick fuse -element and thin fuse -element between the contact piece in turn be provided with the mounting hole on the thick fuse -element be fixed with the arc extinguishing material on the mounting hole. The mounting hole sets up respectively the both ends of four sides of thick fuse -element, the arc extinguishing material sets up respectively on the mounting hole of two adjacent thick fuse -elemenies, the arc extinguishing material is with adjacent thick fuse -element vacuole formation, thin fuse -element setting is in in the cavity, the arc extinguishing material is silica gel. Beneficial effect: the utility model provides an arc extinguishing fusible core be provided with the mounting hole on the thick fuse -element be fixed with the arc extinguishing material on the mounting hole, practiced thrift the quartz sand greatly, and simple structure, equipment simultaneously is convenient, instant arc extinguishing.
Description
Technical field
This utility model relates to the technical field of fuse, particularly relates to a kind of arc extinguishing fusible core.
Background technology
Fuse refers to when electric current exceedes setting, makes melt fuse with the heat that itself produces, and a kind of electrical equipment of disconnecting circuit, fuse is also known as electric fuse.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten with the heat that himself produces, so that circuit disconnects；Use a kind of circuit brake that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and electrical equipment, as the protector of short circuit and overcurrent, is apply one of most common protector.Existing fusible core there is no the effect of arc extinguishing, and is all often directly carry out arc extinguishing at tubular body filled stone sand, assembles complexity.
Summary of the invention
This utility model provides a kind of arc extinguishing fusible core, it is achieved when melt fuses, the fusible core of arc extinguishing at once.
In order to solve above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of arc extinguishing fusible core, including two contact chips, has been arranged alternately thick melt and thin melt between described contact chip, has been provided with installing hole, is fixed with arc quenching material on described installing hole on described thick melt.
Further, described installing hole is separately positioned on the two ends on the described upper and lower surface of thick melt；Described arc quenching material is arranged on the installing hole of two adjacent thick melts.
Further, described installing hole is separately positioned on the two ends of four sides of described thick melt, described arc quenching material is separately positioned on the installing hole of two adjacent thick melts, described arc quenching material and adjacent described thick melt composition cavity, and described thin melt is arranged in described cavity.
Preferably, described arc quenching material is the quartz sand tabletting being made up of quartz sand.
Preferably, described arc quenching material is silicone rubber.
Preferably, described arc quenching material is silica gel.
Preferably, described thin melt is filamentary silver, aluminium wire or aerdentalloy silk.
Preferably, described thick melt is silver-nickel, Kufil or corronil material.
Preferably, described thin melt is coated with one layer of lead or stannum.
Preferably, described thick melt is additionally provided with multiple through hole.
This utility model provides a kind of arc extinguishing fusible core, is provided with installing hole, is fixed with arc quenching material, is greatly saved quartz sand on described installing hole on described thick melt；And simple in construction, simultaneously easy to assembly, instant arc extinguishing.
Accompanying drawing explanation
Fig. 1 is this utility model one arc extinguishing fusible core structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, specifically illustrating embodiment of the present utility model, accompanying drawing is only for reference and illustrates to use, and does not constitute the restriction to this utility model scope of patent protection.
As it is shown in figure 1, a kind of arc extinguishing fusible core, including two contact chips 1, between described contact chip 1, it is arranged alternately thick melt 2 and thin melt 4, described thick melt 2 has been provided with installing hole 3, described installing hole 3 is fixed with arc quenching material 5.Described installing hole 3 is separately positioned on the two ends on the described upper and lower surface of thick melt 2；Described arc quenching material 5 is arranged on the installing hole 3 of two adjacent thick melts 2；Or described installing hole 3 is separately positioned on the two ends of four sides of described thick melt 2, described arc quenching material 5 is separately positioned on the installing hole 3 of two adjacent thick melts 2, described arc quenching material 5 forms cavity with adjacent described thick melt 2, and described thin melt 4 is arranged in described cavity.Described arc quenching material 5 is the quartz sand tabletting being made up of quartz sand or described arc quenching material 5 is silicone rubber, or described arc quenching material 5 is silica gel.Described thin melt 4 is filamentary silver, aluminium wire or aerdentalloy silk.Described thick melt 2 is silver-nickel, Kufil or corronil material.Described thin melt 4 is coated with one layer of lead or stannum.Described thick melt 2 is additionally provided with multiple through hole 6, it is possible to reduce the overall weight of thick melt.
Above disclosed it is only preferred embodiment of the present utility model, it is impossible to limit rights protection scope of the present utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
