In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Referring to Fig.1-2, a kind of reusable fuse, including shell 1 and movable chamber 16, movable chamber 16 are mounted on outer
In shell 1, it is filled with ER fluid 15 in movable chamber 16, sliding block 5 is installed in movable chamber 16, the lower section of sliding block 5 is provided with air bag
6, the top of sliding block 5 is fixedly connected with universal driving shaft 4, and the outside of sliding block 5 is provided with separation layer, and the material of separation layer is anti-corrosion rubber
Glue, sliding block 5 and the inner wall of movable chamber 16 are slidably connected, and universal driving shaft 4 passes through movable chamber 16, are socketed with sealing ring 11 in lead rod 12,
Sealing ring 11 is connected in movable chamber 16, and universal driving shaft 4 is fixedly connected with U-shaped axis 3 far from one end of sliding block 5, is fixed on U-shaped axis 3
It is connected with pressing axis 2, pressing axis 2 passes through shell 1, and the two sides of shell 1 are symmetrically installed with connecting line 9, are symmetrically installed in shell 1
Connecting plate 14 corresponding with connecting line 9, connecting plate 14 are electrically connected with connecting line 9, and the both ends of U-shaped axis 3 are fixedly connected to sliding
End 8, sliding end 8 is slidably connected with connecting plate 14, and the downside of sliding end 8 is connected with second spring 10, and second spring 10 is far from sliding
One end of moved end 8 is fixedly connected with the inner wall of shell 1, and the two sides of movable chamber 16 are symmetrically inserted with lead rod 12, one end of lead rod 12
It is connected with fixing end 13, conducting wire 7 is connected between fixing end 13 and sliding end 8, it is right with sliding end 8 to be symmetrically installed on shell 1
The clamping mechanism answered, clamping mechanism include axis 17 and the first spring 18, and the first spring 18 is socketed on axis 17, and axis 17 is inserted
It is located on shell 1, one end of the first spring 18 is fixedly connected with axis 17, and the other end and shell 1 of the first spring 18 are fixed to be connected
It connects, axis 17 is inclined-plane close to the side of connecting plate 14.
When the connection of connecting line 9 is when circuit, connecting line 9 is electrically connected with connecting plate 14, connecting plate 14 and sliding end 8
For electrical connection, wherein the ER fluid 15 in movable chamber 16 is conductor, is access between two lead rods 12, then two connecting lines 9
Between also be access, circuit is normal at this time, being capable of good normal use under normal current conditions.
When the electric current flowed through in shell 1 is excessive, then the electric current for flowing through ER fluid 15 will increase accordingly, root
According to the intrinsic property of ER fluid 15, when electric current increases to 15 maximum critical value of ER fluid, ER fluid 15 will
It is changed into solid-state from liquid, wherein the volume of ER fluid 15 and the size of electric field are directly proportional, then when flowing through electric current increase
It waits, when ER fluid 15 is changed into solid, volume will be will increase, and wherein the light weight of air bag 6 is in liquid level position always,
So that air bag 6 and sliding block 5 rise, sliding block 5 will drive corresponding U-shaped during rising for meeting during ER fluid 15 changes
Axis 3 and pressing axis 2 rise, and U-shaped axis 3 will drive sliding end 8 during rising and slide with respect to connecting plate 14, and sliding end 8 exists
During sliding on connecting plate 14, circuit is in the state of access, when ER fluid 15 is expanded to sliding end 8 and connecting plate 14
When the degree of disengaging, sliding end 8 and connecting plate 14 are detached from, it will so that circuit disconnects, sliding end 8 will during sliding
It is gradually mobile along the inclined-plane of axis 17, after sliding end 8 is moved through axis 17, acts on, make in the elastic force of the first spring 18
The position that axis 17 stops sliding end 8 is obtained, its downslide is avoided, thus when current overload in circuit, it is effective to disconnect
Open circuit.
When circuit restores normal, due to being in off state in shell 1, then the electric current of ER fluid 15 is flowed through certainly
It can be so reduced to lower critical value, to revert to liquid condition, since sliding end 8 has been clamped by axis 17, sliding end 8 can not
It is contacted with connecting plate 14, even if movable chamber 16 reverts to liquid and will not still make circuit pathways, therefore, to assure that after circuit is normal
User pulls the one end in 17 outside of axis, slides into connecting plate 14 so that sliding end 8 is smoothly lower, while pressing pressing axis downwards
2, circuit could circulate, and circuit is effectively protected, and can repeat, can save cost, and timely restoring circuit.
