Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word.
The utility model provides a kind of magnetic force and recovers safety device, including insurance institution and magnetic force recovery mechanism.
As shown in Figure 1, the insurance institution includes insulation shell 1, glass material is used to be made.Its described insulation shell 1 is in
The hollow form of both ends open, the both ends of the insulation shell 1 are respectively arranged with the first conductive cap 21 and the second conductive cap 22, pass through
One conductive cap 21 and the second conductive cap 22 seal the both ends of insulation shell 1.Bimetal leaf 3 is provided in the insulation shell and is led
Electric block 4, the bimetal leaf 3 have the characteristic of temperature distortion, when bimetal leaf 3 is heated, can be bent to one end, described double
Sheet metal 3 is nonelastic, and after it, which is heated, is bent to one end, cooling again will not be such that bimetal leaf 3 resets, it is necessary to by outer
Power, which gently moves, can just make its reset.
The left end of the bimetal leaf 3 is electrically connected with the first conductive cap 21, may be employed the modes such as welding, riveting realize it is double
The connection of 3 and first conductive cap 21 of sheet metal.The right end of the conducting block 4 is electrically connected with the second conductive cap 22, and conducting block 4 is same
Sample is connected using modes such as welding, rivetings with the second conductive cap 22.Under natural conditions, the right end of bimetal leaf 3 always with conduction
The left end of block 4 is in contact, and realizes the conducting of bimetal leaf 3 and conducting block 4.The safety device is linked into main circuit during use
In, using the first conductive cap 21 and the second conductive cap 22 as two terminals, the electric current in main circuit is made to flow through 3 He of bimetal leaf
Conducting block 4.When the electric current in main circuit is excessive, bimetal leaf 3 can be made to generate heat, and then bent, make the right side of bimetal leaf 3
End is separated with conducting block 4, and the electric current in main circuit is disconnected, plays the role of fuse.Insurance dress provided by the utility model
It puts identical with the application method of conventional fuse silk.
Since the bimetal leaf 3 is nonelastic, after it, which is heated, is bent to one end, cooling again will not make bimetallic
Piece 3 resets, it is necessary to which the front end of bimetal leaf 3 is gently moved by external force can just make its reset.The both ends of insulation shell 1 are
It is sealed by the first conductive cap 21 and the second conductive cap 22, it is difficult to open, it is impossible to be extend into double gold by instrument in insulation shell 1
Belong to piece 3 to reset.
As shown in Figure 2 and Figure 3, magnetic force recovery safety device provided by the utility model further includes magnetic force recovery mechanism, passes through
Magnetic force resets bimetal leaf 3.The magnetic force recovery mechanism is fixed on the outer surface of insulation shell 1.The magnetic force recovers
Mechanism includes the first shell 5 being symmetrically arranged and second housing 6, first shell 5 and second housing 6 pass through gluing
Mode is fixed on the outer surface of insulation shell 1.It is provided with partition plate 7 between first shell 5 and second housing 6, described first
Shell 5 and second housing 6 are magnetizer material, and partition plate 7 is un-conducted magnetic material, what first shell 5 and second housing 6 formed
A cylindrical cavity is provided in housing, cylindrical empty intracavitary is provided with a strip magnet 8, and the strip magnet
8 can be around its rotating middle part.Knob, the knob and strip magnet are provided in the outside of the first shell 5 and second housing 6
8 connections, drive strip magnet 8 to rotate by turn knob.When strip magnet 8 turns to vertical position, i.e. n poles and s
Extremely up and down arrangement when, the magnetic line of force forms closed circuit in the first shell 5 and second housing 6 respectively, and no magnetic line of force passes through bimetallic
Piece 3 will not generate magnetic force to bimetal leaf 3.After strip magnet 8 rotates 90 degree, n poles and the ultra-Left right arrangements of s, n poles and s poles
The first shell 5 and second housing 6 are respectively toward to, the magnetic line of force is formed to bimetal leaf 3 to s poles from n pole to magnetizer at this time and closes
It closes, can generate a magnetic force to bimetal leaf 3 at this time, its right end is attracted to be moved upward, and then realize and reset and conducting block 4
Left end is in contact.Safety device can reuse after reset, and cost is greatly saved in the safety device that need not more renew.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization.It can be applied to the field of various suitable the utility model completely.For those skilled in the art,
Other modification is easily achieved.Therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details is not limited to new and shown here as the legend with description.
