Coil 140 is set on coil rack 130 and is positioned at second area.
Fixed mount 150 may be provided in the 3rd region, and is arranged between the second end 133 of coil rack 130 and yoke 120.In implementing one, as it is shown on figure 3, fixed mount 150 can be structure as a whole with coil rack 130；In another embodiment, as shown in Figure 4, fixed mount 150a can be two independent parts with coil rack 130.
Specifically, as it is shown on figure 3, fixed mount 150 includes 152, depressed part 154 of a pedestal and a plurality of boss 156.Wherein, depressed part 154 is formed on the inside of pedestal 152, including a periphery 1542；A plurality of boss 156 are symmetrically disposed on pedestal 152 and are positioned on the periphery 1542 of depressed part 154；Each boss 156 includes one first mating surface 1562 and at least one second mating surface 1564, and the first mating surface 1562 is the inner face closing on depressed part 154 center on boss 156, and the first mating surface 1562 can be used for fixed magnet 170 and coordinates.Second mating surface 1564 is the side end face that on boss 156, circumferentially face 1542 is adjacent with adjacent boss 156.
As shown in Figure 4, fixed mount 150a includes a pedestal 152a, through hole 154a, an a plurality of boss 156a and a plurality of side muscle 158a.Wherein, through hole 154a is formed on the inside of pedestal 152a and runs through pedestal 152a, through hole 154a along the thickness direction of pedestal 152a and includes a periphery 1542a(in other words, and the periphery 1542a on pedestal 152a is around forming this through hole 154a)；A plurality of boss 156a are symmetrically disposed on pedestal 152a and are positioned on the periphery 1542a of through hole 154a；The structure of boss 156a is identical with the structure of above-mentioned boss 156, does not repeat them here.A plurality of side muscle 158a are symmetrically disposed on the outside of pedestal 152a, can be used for fixing yoke 120.
As it is shown in figure 5, magnetic conductor 160 can be made up of low magnetic resistance ferrous material etc..Magnetic conductor 160 includes a matrix 162 and a plurality of breach 163.Matrix 162 is substantially in the form of a ring, its outer peripheral face can match with the periphery 1542/1542a of fixed mount 150/ fixed mount 150a, such as, the outer peripheral face of matrix 162 can with the periphery 1542/1542a tight fit of fixed mount 150/ fixed mount 150a thus being installed to fixed mount 150/ fixed mount 150a by matrix 162.A plurality of breach 163 are symmetrically disposed on matrix 162, and with the boss 156/156a one_to_one corresponding of fixed mount 150/ fixed mount 150a, so, when magnetic conductor 160 is installed to fixed mount 150/ fixed mount 150a, boss 156/156a can enter in the breach 163 of correspondence, it is possible to by matrix 162 and fixed mount 150/ fixed mount 150a location.

Shown in Fig. 5, static iron core 180 includes a projection 183 and a flange 182.As it is shown in figure 1, projection 183 is arranged on the inside of coil 140；Flange 182 is along the circumferentially disposed of projection 183 axis being approximately perpendicular to projection 183, and the external diameter of flange 182 is no less than the external diameter of magnetic conductor 160.Flange 182 is folded between Magnet 170 and coil rack 130, thus being fixed by static iron core 180.Due to the Magnet 170 length on the axial direction of Magnet 170 or thickness, more than the magnetic conductor 160 length on the axial direction of magnetic conductor 160 or thickness, therefore, the surface contacted with Magnet 170 on static iron core 180 and magnetic conductor 160 close on and form first air gap or point magnetic air gap 165 between the end face of static iron core 180.
As shown in Figure 1, Figure 2 with shown in Fig. 6, dynamic iron core 190 is slidably mounted in the inside of coil 140.Dynamic iron core 190 includes a body of rod 192, and forms the block 193 on the body of rod 192 and a connecting hole 195 formed in the body of rod 192 end.The body of rod 192 is inserted in the installing hole 135 of coil rack 130, and forms an interstice or the main air gap 210 of magnetic circuit between the body of rod 192 and yoke plate 110.In one embodiment, connecting hole 195 can be long gain, as shown in Figure 6；In another embodiment, connecting hole 195a can be circular hole, as shown in Figure 7.As shown in Figure 8, connecting hole 195a/ connecting hole 195 is by installing different accessory part 196a, in order to realize the function resetting or threading off in other position.Additionally, dynamic iron core 190 also includes a work surface 194；Work surface 194 and connecting hole 195 are positioned at the two ends of the body of rod 192.
As depicted in figs. 1 and 2, energy-storage travelling wave tube 200 can be compression spring, and it is arranged on the inside of coil rack 130 and is set on static iron core 180 and dynamic iron core 190.Specifically, one end of energy-storage travelling wave tube 200 is supported on the block 193 of dynamic iron core 190, and the other end of energy-storage travelling wave tube 200 is supported on the flange 182 of static iron core 180.
The above-mentioned concrete structure for magnetictrip in one embodiment of the invention 100, the magnetic circuit of brief description magnetictrip 100 and operation principle thereof.
The magnetic circuit of Magnet 170 substantially can divide two parts: the first magnetic flux path shown in Fig. 9 or main magnetic circuit footpath and the second magnetic flux path shown in Figure 10 or point magnetic-path.As it is shown in figure 9, the first magnetic flux path is the useful magnetic flux path being returned to Magnet 170 by static iron core 180, the dynamic work surface 194 of iron core 190, yoke plate 110 and yoke 120；As shown in Figure 10, the second magnetic flux path is point magnetic-path not utilized being returned directly to Magnet 170 by static iron core 180, magnetic conductor 160 and yoke 120.By the adjustment of physical dimension, it is possible to adjust the first magnetic flux path of Magnet 170 and the magnetic flux size of the second magnetic flux path, thus controlling the suction-combining force size to dynamic iron core 190.Such as, the size of Magnet 170 can be changed to adjust the suction-combining force size, or by adjusting the first air gap 165, the dimensional fits of interstice 210 adjust the suction-combining force size and can reduce processing and the rigging error impact on magnetic circuit retentivity.
Being left out the magnetic field of Magnet 170, the magnetic flux path that coil 140 energising produces is divided into two parts: the first magnetic flux path shown in Figure 11 and the second magnetic flux path shown in Figure 12.As shown in figure 11, the first magnetic flux path that coil 140 produces is the magnetic flux path by the work surface 194 of dynamic iron core 190, static iron core 180, Magnet 170, yoke 120 and yoke plate 110；Owing to the magnetic resistance of Magnet 170 is relatively big, therefore, the magnetic flux of the first magnetic flux path that coil 140 produces is less.As shown in figure 12, the second magnetic flux path that coil 140 produces is the magnetic flux path by the work surface 194 of dynamic iron core 190, static iron core 180, magnetic conductor 160, yoke 120 and yoke plate 110；Owing to magnetic conductor 160 is irony permeability magnetic material, its magnetic resistance is less, and therefore, the magnetic flux of the second magnetic flux path that coil 140 produces is more.From Figure 11 and Figure 12, the first magnetic flux path that coil 140 produces and the second magnetic flux path are each through the work surface 194 of dynamic iron core 190, and therefore, the first magnetic flux path and the second magnetic flux path that coil 140 produces are useful magnetic flux.Due to the existence of magnetic conductor 160, effectively reduce the magnetic resistance value of the magnetic flux path of coil 140, advantageously in producing the magnetic flux that the bigger magnetic flux with Magnet 170 is reverse, be conducive to the service behaviour of magnetictrip 100.
The operation principle of magnetictrip 100 is: in off working state, as it is shown in figure 1, utilize first magnetic flux path (as shown in Figure 9) of magnet 170 to provide the suction-combining force for dynamic iron core 190；When this suction-combining force is more than the counter-force of energy-storage travelling wave tube 200 in this condition as compression spring, dynamic iron core 190 is in maintenance state.The suction-combining force of dynamic iron core 190 and energy-storage travelling wave tube 200 such as the compression spring difference to the counter-force size of dynamic iron core 190, are the dynamic iron core 190 retentivity in this maintenance state, reasonably keep force value can bear the impact of vibrations, shock environment by Magnet 170.
In working order, the first magnetic flux path (as shown in figure 11) that formed of magnetic potential formed in coil 140 and the second magnetic flux path (as shown in figure 12), the magnetic field contrary with Magnet 170 is provided, thus weakening Magnet 170 magnetic field the suction-combining force to dynamic iron core 190, make this suction-combining force less than energy-storage travelling wave tube 200 if compression spring is to the dynamic iron core 190 counter-force to dynamic iron core 190, namely dynamic iron core 190 departs from static iron core 180 and starts release, and complete release conditions are as shown in Figure 2.

The schematic diagram that Figure 14 show in another embodiment of the present invention magnetictrip 100c.Magnetictrip 100c is similar to the structure of above-mentioned magnetictrip 100, and difference essentially consists in: static iron core 180c and magnetic conductor 160c is structure as a whole, and the first air gap 165c is between magnetic conductor 160c and yoke 120.Figure 15 is the schematic diagram of the static iron core 180c and magnetic conductor 160c of integrative-structure in Figure 14.As shown in figure 15, static iron core 180c is identical with the structure of static iron core 180, and the structure of magnetic conductor 160c is identical with the structure of magnetic conductor 160, and simply magnetic conductor 160c and static iron core 180c connects into a part.
As it has been described above, by arranging the size that magnetic circuit is optimized and then regulates retentivity by magnetic conductor and air gap etc. in magnetictrip in the embodiment of the present invention, thus meet the requirement of vibrations, impact application environment.It addition, by arranging magnetic conductor in magnetictrip in the embodiment of the present invention so that magnetictrip has double magnetic circuit design flexibly, can either reasonably utilize the magnetic energy of Magnet, maximized can utilize coil energy again.Additionally, design or the mismachining tolerance impact on the working gas gap active force between dynamic iron core, static iron core can be weakened by arranging interstice or the main air gap of magnetic circuit；And, by arranging the flux relationship of point magnetic air gap adjustable main magnetic circuit and point magnetic circuit, meet main air-gap flux demand.
