Referring to Fig.1-3, a kind of novel energy-conserving fuse, including shell 3, the two sides of shell 3 symmetrically offer opening, and two
It is connected with mounting blocks 1 in opening, electromagnet 4 is installed in shell 3, coil 5, the left and right of electromagnet 4 are wound on electromagnet 4
Two sides are symmetrically installed interior fixed frame 6, and interior fixed frame 6 is connected with output lead 2 far from the side of coil 5, and output lead 2 passes through shell
Body 3, output lead 2 are fixedly connected with external contact 20, and interior loop 5 is fixedly connected with interior contact 17, interior contact 17 and external contact 20
Between intermediate contact 18 is installed, between interior contact 17, intermediate contact 18 and external contact 20 for electrical connection, the one of intermediate contact 18
Side is fixedly connected with slide-bar 14, is socketed with second spring 16 on slide-bar 14, and slide-bar 14 passes through shell 3, intermediate contact 18 it is another
Side is fixedly connected with universal driving shaft 7, has been fixedly attached limit sleeve 19 on universal driving shaft 7 and slide-bar 14, the limit on slide-bar 14 is arranged in
Position set 19 is located at close to the side of intermediate contact 18, and the limit sleeve 19 being arranged on universal driving shaft 7 is located remotely from intermediate contact 18
Side, two limit sleeves 19 are installed in shell 3, and one end of second spring 16 is fixedly connected with shell 3, second spring 16
The other end is fixedly connected with limit sleeve 19, and universal driving shaft 7 also passes through shell 3;
The both ends of coil 5 are plugged in respectively in interior fixed frame 6, and the upper and lower ends of electromagnet 4 are symmetrically arranged with metal plate 11,
The inner wall of shell 3 is fixedly connected with limit shaft 12 corresponding with metal plate 11, and limit shaft 12 passes through metal plate 11, metal plate 11 with
The first spring 13 is connected between shell 3, two 11 central symmetries of metal plate are fixedly connected with clump weight 10, two metal plates 11
One end far from clump weight 10 is fixedly connected with fixing axle 9, and fixing sleeve 8 corresponding with fixing axle 9 is fixedly installed in shell 3,
Fixing axle 9 is plugged in fixing sleeve 8;
Universal driving shaft 7 is equipped with fixed block 21 far from one end of intermediate contact 18, and sliding is inserted with sliding block 23 in fixed block 21,
One end of sliding block 23 is plugged in fixing sleeve 8, and the other end of sliding block 23 is fixedly connected with pulling shaft 15, the inner wall of 21 side of fixed block
Multiple turn troughs are provided with, ball 22 is installed in turn trough, sliding slot is offered on the inner wall of 21 other side of fixed block, is consolidated on sliding block 23
Surely it is connected with limited block corresponding with sliding slot, limited block is slidably connected with sliding slot, and multiple balls 22 contact with each other with sliding block 23, energy
Enough reduce the frictional force that sliding block 23 moves in fixed block 21, limited block slides in sliding slot, plays the role of limit.
Shell 3 is connected into circuit, two output leads 2 and connection, under normal circuit situation, interior contact 17, in
Between the contact electrical connection between each other of contact 18 and external contact 20, electric current is from the output lead 2 of side by coil 5 from the other side
Output lead 2 flows out, and due to having electric current to pass through on coil 5, according to Ampere's law, the size of electric current is directly proportional to magnetic field size,
Magnetic field then will be generated on corresponding electromagnet 4, so that electromagnet 4 has magnetism, since the position of electromagnet 4 is fixed,
The metal plate 11 at 4 both ends of electromagnet can be close to electromagnet 4 under magneticaction, but since metal plate 11 is by the first spring 13
Restrain, within the scope of rated current, between metal plate 11 and electromagnet 4 magnetic force less than the first spring 13 elastic force so that metal
Plate 11 will not be contacted with electromagnet 4, and circuit is in channel status always.
When current overload in circuit, magnetic field will be greater than first to the magnetic force of both ends metal plate 11 on electromagnet 4
The elastic force of spring 13, electromagnet 4 will make metal plate 11 contact with electromagnet 4 sucking action of metal plate 11, metal plate
11 will drive the movement accordingly of fixing axle 9 in the process of moving, and fixing axle 9 is continuous close to sliding block 23, gold in fixing sleeve 8
When category plate 11 and electromagnet 4 contact, fixing axle 9 will be moved to the bosom in fixing sleeve 8, and fixing axle 9 is mobile
Have the function of squeezing to sliding block 23 in the process and push, since the side of sliding block 23 is inclined-plane, then fixing axle 9 will will push sliding block
23 towards moving in fixed block 21, when fixing axle 9 is moved to it is innermost in fixing sleeve 8 when, sliding block 23 will be squeezed out
It goes, sliding block 23 and fixing sleeve 8 are detached from;
Second spring 16 loses the external force of drawing, then second spring 16 will be shunk, process of the second spring 16 in contraction
Middle slide-bar slide-bar 14 slides in and out, and intermediate contact 18 will also move, and intermediate contact 18 will be de- with interior contact 17, external contact 20
From the circuit in shell 3 will will disconnect, then entire circuit will also will disconnect, and effectively play the role of protecting circuit.
It excludes to open the mounting blocks 1 of 3 two sides of shell in circuit after overload problem, pulls pulling shaft 15, universal driving shaft 7 is drawn
After the position of dynamic only close fixing sleeve 8, push pulling shaft 15 that sliding block 23 is inserted into fixing sleeve 8, interior contact 17, intermediate contact 18
Electrical connection will be contacted between each other again with external contact 20, then circuit will restore regular path, it avoids replacing new fuse,
Also it can timely repair so that circuit restores normal use.
More than, it is merely preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any
Those familiar with the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its invents
Design is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
