Description

Technical Field

[0001] The present invention relates to the technical field of weak magnetic signal detection, and specifically to a novel amorphous wire winding structure. Background Art

[0002] In 1992, Professor Mohri and others at Nagoya University in Japan discovered the magnetic impedance (MI) effect in FeCoSiB amorphous wires. Later, Panina et al. made a specific analysis of the origin of this phenomenon and named this effect with strong response and high sensitivity as the Giant magnetic impedance (GMI) effect. Due to its good soft magnetic properties such as high magnetic permeability, low coercivity, low remanence, high conductivity, and the advantages of simple preparation and easy integration, amorphous wire has become an important carrier for people to study the GMI effect.

[0003] To improve the GMI effect, the present invention proposes two novel amorphous wire winding structures, namely the folded amorphous wire winding structure and the parallel winding structure. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention discloses a novel amorphous wire winding structure to solve the problems raised in the above background art.

[0006] (2) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A novel amorphous wire winding structure, comprising:

[0008] A support plate, the top of the support plate is fixedly connected with a cylindrical rod, and a rubber sleeve is sleeved on the outer wall of the cylindrical rod;

[0009] A locking assembly, the locking assembly is arranged on the top of the support plate, the locking assembly includes a plurality of cylindrical blocks, and two fixing blocks are fixedly connected to the top of each of the plurality of cylindrical blocks, and a moving block is slidably connected to the top of each of the plurality of fixing blocks.

[0010] Preferably, a cylindrical sleeve is arranged inside the cylindrical rod, second electric wires are arranged at both ends of the cylindrical sleeve, and one end of each of the two second electric wires is fixedly connected with an iron sheet.

[0011] Preferably, an insulating sleeve is arranged inside the cylindrical rod, third electric wires are fixedly connected to both ends of the insulating sleeve, one end of each of the two third electric wires is fixedly connected with an iron sheet, and a round hole is formed inside the iron sheet.

[0012] Preferably, both ends of the rubber sleeve are fixedly connected to a first electric wire, and one end of two of the first electric wires is fixedly connected to an iron sheet.

[0013] Preferably, the top ends of the plurality of moving blocks are fixedly connected with moving rods, one end of the plurality of moving rods is fixedly connected with a clamping block, and the plurality of clamping blocks are respectively slidably and interlacedly connected with the plurality of circular holes.

[0014] Preferably, the tops of the plurality of fixed blocks are each provided with a fixing groove, and the plurality of fixed grooves are respectively connected to the plurality of movable blocks in a sliding and interlaced manner.

[0015] Preferably, a compression spring is disposed inside each of the plurality of moving blocks, and one end of each of the compression springs is fixedly connected to one end of the moving block.

[0016] The present invention discloses a novel amorphous wire winding structure, which has the following beneficial effects:

[0017] 1. The invention discloses a novel amorphous wire winding structure, and a folded winding probe structure is to connect one end of two 5cm amorphous wires as a sensitive magnetic core, which is equivalent to two amorphous wires in series. The impedance is proportional to the length of the amorphous wire and inversely proportional to its radius. For the measurement method of the folded winding method, the folded amorphous wire is equivalent to two 5cm amorphous wires in series, which increases the length of the amorphous wire, so the impedance increases. In addition, we can find that the GMI effect obtained by the folded winding method is significantly enhanced than the GMI effect obtained by the single-wire winding method. This is because the induced magnetic field and the external magnetic field generated around the single amorphous wire through which the AC signal passes affect each other. After superposition, the magnetic field strength along the axial direction of the amorphous wire is weakened, and the effect of the axial magnetic field on the amorphous wire is also weakened. For the folded winding method, the induced magnetic fields generated by the folded back amorphous wire and the unfolded amorphous wire part are equal in size and opposite in direction, so they cancel each other out, leaving only the effect of the external magnetic field on the amorphous wire. Therefore, the folded winding method helps to improve the GMI effect of the amorphous wire.

[0018] 2. The invention discloses a novel amorphous wire winding structure which is equipped with a parallel winding method, that is, connecting two amorphous wires with a length of 5 cm at both ends in parallel, which is equivalent to connecting two amorphous wires in parallel. The amorphous wires are connected side by side in the circuit. Although the effect of the induced magnetic field generated by the amorphous wires is also superimposed and the interference effect is enhanced, the response of each amorphous wire to the external magnetic field is collected by the coil. Therefore, winding multiple amorphous wires side by side with a copper coil can also make the GMI effect more significant. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0024] An embodiment of the present invention discloses a novel amorphous wire winding structure, as shown in Figure 1 -4, including:

[0025] Support plate 1, the support plate 1 plays a supporting role. A cylindrical rod 2 is fixedly connected to the top end of the support plate 1. The cylindrical rod 2 is a large glass tube, which is evenly wound with 1600 turns of copper wire with a diameter of 30 um and fixed on the circuit board. The amorphous wire probe is fixed on the foam and placed in the center of the Helmholtz coil to ensure that the probe is in a uniform magnetic field. In the overall structural design, the GMI probe has a reasonable structure, the testing method is correct, and the parameters of the testing instrument are set reasonably, so that the GMI effect is significantly improved. A rubber sleeve 3 is sleeved on the outer wall of the cylindrical rod 2;

[0026] Locking component, the locking component is arranged at the top end of the support plate 1. The locking component includes a plurality of cylindrical blocks 4. Two fixed blocks 401 are fixedly connected to the top ends of the plurality of cylindrical blocks 4. A moving block 402 is slidably connected to the top ends of the plurality of fixed blocks 401.

[0027] Inside the cylindrical rod 2, there is a cylindrical sleeve 7. At both ends of the cylindrical sleeve 7, there are second electric wires 701. The amorphous wire sensitive probe structure places an amorphous wire with a diameter of 125 μm and a length of 5 cm in a spotting capillary with a diameter of 150 μm and a length of 5 cm. Then, the spotting capillary and another amorphous wire of the same size are placed into a spotting capillary with a diameter of 300 μm and a length of 5 cm. The two ends of the amorphous wire in the spotting capillary with a diameter of 150 μm are respectively connected to the first hole and the third hole on the PCB board. The two ends of the other amorphous wire are respectively connected to the second hole and the fourth hole on the PCB board. The two ends of the copper wire wound around the spotting capillary with a diameter of 300 μm are respectively connected to the fifth hole and the sixth hole on the PCB board. The copper wire is wound 1,600 turns in total. A wire is led out from each of the first to sixth holes for changing and testing the amorphous wire structure. The instruments used for testing include a pulse function arbitrary wave generator (model 81160A), a DC regulated power supply (model E36312A DC), a Helmholtz coil, an amorphous wire sensitive probe, an LCR meter (model IM3536), and a computer. After the amorphous wire probe structure is made, it is fixed in the center of a foam with a specification of 10×10×10 cm. The foam is placed in the center of the Helmholtz coil to ensure that the magnetic field received by the amorphous wire probe is a uniform magnetic field. The second electric wire 701 has a diameter of 150 μm, and one end of each of the two second electric wires 701 is fixedly connected to an iron sheet 802.

[0028] Inside the cylindrical rod 2, there is an insulating sleeve 8. At both ends of the insulating sleeve 8, there are third electric wires 801 fixedly connected. The third electric wire 801 has a diameter of 150 μm. One end of each of the two third electric wires 801 is fixedly connected to an iron sheet 802. A circular hole is opened inside the iron sheet 802. For non-diagonal GMI measurement, after an alternating current signal is passed through the amorphous wire, based on the electromagnetic induction phenomenon, a circumferential induced magnetic field will be generated in the amorphous wire. Then, the copper coil wound around the amorphous wire will collect the changes in this magnetic field around the amorphous wire. The LCR meter used for testing impedance is model IM3536, and its working principle is the bridge balance principle. The magneto-impedance effect can be tested through the curve of the magneto-impedance Z changing with the magnetic field H. The change rate of the impedance value Z(H) at any magnetic field relative to the impedance value Z(Hmax) at the saturation magnetic field is the GMI ratio, that is, the magneto-impedance effect.

[0029] At both ends of the rubber sleeve 3, there are first electric wires 6 fixedly connected. The first electric wire 6 has a diameter of 300 μm. One end of each of the two first electric wires 6 is fixedly connected to an iron sheet 802. The tops of multiple moving blocks 402 are fixedly connected to a moving rod 403. One end of each of the multiple moving rods 403 is fixedly connected to a clamping block 404. The multiple clamping blocks 404 are respectively slidably inserted and connected with the multiple circular holes.

[0030] The top ends of multiple fixing blocks 401 are each provided with a fixing groove, and the multiple fixing grooves are respectively slidably inserted and connected with multiple moving blocks 402. Compression springs 5 are arranged inside the multiple moving blocks 402, and one ends of the multiple compression springs 5 are fixedly connected to one ends of the moving blocks 402.

The iron sheet 802 moves between the two clamping blocks 404. Release the moving rod 403. The compression spring 5 loses the external force and makes a reset movement. The moving block 402 is stressed and moves horizontally in the direction away from the compression spring 5. The clamping block 404 moves into the circular hole, restricting the horizontal movement of the iron sheet 802;

The compression spring 5 is stressed and compressed. The compression spring 5 is in a compressed state. The iron sheet 802 moves between the two clamping blocks 404. Release the moving rod 403. The compression spring 5 loses the external force and makes a reset movement. The moving block 402 is stressed and moves horizontally in the direction away from the compression spring 5. The clamping block 404 moves into the circular hole, restricting the horizontal movement of the iron sheet 802;

[0034] Then hold the third wire 801 by hand. The third wire 801 is stressed and moves in the direction close to the second hole. The iron sheet 802 moves horizontally along with the first wire 6. Then hold the moving rod 403 by hand. The moving rod 403 is stressed and moves horizontally in the direction close to the compression spring 5.
