Description
Technical field
This utility model relates to fuse technologies field, particularly relates to a kind of vast capacity fuse.
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.Along with current needs becomes larger, it is long to there is the response time in the technology of direct overstriking fuse, and easily causes point discharge.Meanwhile, existing Large Copacity fuse often structure is complicated.
Summary of the invention
This utility model provides a kind of vast capacity fuse, and the response time is short, without the Large Copacity fuse of point discharge.
In order to solve above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of vast capacity fuse, including fuse, described fuse includes body, connects terminal；Be provided with outer cap at the two ends of described body, described outer cap connects described connection terminal；Being provided with interior cap between described body and described outer cap, described outer cap electrically connects with described interior cap；In described body, it is provided with two conductive plates, is provided with elastic mechanism between each described conductive plate and interior cap, between two described conductive plates, is provided with at least four fuses；Open at one end at described interior cap is provided with conducting ring, and described conducting ring electrically connects with described conductive plate；The side of described conducting ring is provided with insulating barrier.
Further, described outer cap both sides being provided with card convex, the arranged outside at described interior cap has the groove mated with described card convex.
Preferably, described insulating barrier is insulated sleeve.
Further, described elastic mechanism includes at least two spring, and described spring connects described conductive plate and the bottom of interior cap respectively.
Preferably, the quantity of described fuse is 4, and the quantity of described spring is 4.
Preferably, in described body, it is filled with arc quenching material.
Preferably, described arc quenching material is quartz sand.
Preferably, described body is epoxy resin body or pottery body.
Preferably, described connection terminal is copper tip, the silver-plated terminal of copper or copper nickel plating terminal.
Preferably, outside described body, it is coated with explosion-proof layer.
This utility model provides a kind of vast capacity fuse, is provided with two conductive plates, is provided with elastic mechanism, is provided with at least four fuses between two described conductive plates between each described conductive plate and interior cap in described body；Open at one end at described interior cap is provided with conducting ring, and described conducting ring electrically connects with described conductive plate；The side of described conducting ring is provided with insulating barrier.When short circuit or current overload, fuse disconnects, and conductive plate is drawn in insulating barrier by elastic mechanism from conducting ring position, it is achieved instant isolation tubular body and outside conduction, and without point discharge.
Accompanying drawing explanation
Fig. 1 is this utility model one vast capacity fuse structure schematic diagram.
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 vast capacity fuse, including fuse, described fuse includes body 1, connects terminal 2；Be provided with outer cap 3 at the two ends of described body 1, described outer cap 3 connects described connection terminal 2；Being provided with interior cap 4 between described body 1 and described outer cap 3, described outer cap 3 electrically connects with described interior cap 4；In described body 1, it is provided with two conductive plates 5, is provided with elastic mechanism between each described conductive plate 5 and interior cap 4, between two described conductive plates 5, is provided with at least four fuses 11；Described elastic mechanism includes at least two spring 6, and described spring 6 connects the bottom of described conductive plate 5 and interior cap 4 respectively.In the present embodiment, the quantity of described fuse 11 is 4, and the quantity of described spring 6 is 4.
Open at one end at described interior cap 4 is provided with conducting ring 41, and described conducting ring 41 is electrically connected described outer cap 3, interior cap 4 and conductive plate 5；It is provided with insulating barrier 42 between the bottom of described conducting ring 41 and described interior cap 4.Described outer cap 3 both sides are provided with card convex, and the arranged outside at described interior cap 4 has the groove mated with described card convex.In the present embodiment, described insulating barrier 42 is insulated sleeve.It is filled with arc quenching material in described body 1.Described arc quenching material is quartz sand.Described body 1 is epoxy resin body or pottery body.Described connection terminal 2 is copper tip, the silver-plated terminal of copper or copper nickel plating terminal.It is coated with explosion-proof layer 12 outside described body 1.
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.
