Description

Technical Field

[0001] This invention relates to the field of split-type Hall current sensor technology, and more specifically, to a split-type Hall current sensor. Background Technology

[0002] Hall current sensors are circuit instruments. Based on the magnetic balance Hall principle, according to the Hall effect principle, when a current Ic is passed through the control current terminal of the Hall element and a magnetic field with magnetic induction intensity B is applied in the normal direction of the Hall element plane, a potential VH will be generated in the direction perpendicular to the current and the magnetic field (i.e., between the Hall output terminals), called the Hall potential, whose magnitude is proportional to the product of the control current I and the magnetic induction intensity B. That is, where: K is the Hall coefficient, determined by the material of the Hall element; I is the control current; B is the magnetic induction intensity; and VH is the Hall potential. In existing technology, when using existing split-type Hall current sensors, it is not possible to quickly disengage the conduit connecting to the outside when maintenance or replacement is required. This is usually due to the complex design of the conduit connection, which may require specific tools or follow cumbersome steps to complete the disassembly. This design not only increases the difficulty and time of maintenance, but may also delay repair work in emergency situations, affecting the normal operation of external equipment.

[0003] Secondly, existing split-type Hall current sensors cannot be quickly fixed when installing or replacing conduits. Traditional fixing methods may require manually adjusting the position of the conduit and then using screws, clamps or other fasteners to fix it. This process is both time-consuming and labor-intensive, especially on production lines or maintenance sites, where this inefficient fixing process may significantly reduce work efficiency.

[0004] In addition, the inconvenience of existing split-type Hall current sensors in use also lies in the convenience of their overall design. They cannot fix the housing or quickly replace the bakelite cover, which makes them inconvenient to use. Summary of the Invention

[0011] The invention is further configured such that a wire clamping plate is connected to the spring, and wire clamping blocks are evenly distributed on the wire clamping plate. The cooperation of each component facilitates the completion of the process of fixing the wire tube.

[0012] The present invention is further configured such that the mounting assembly includes a fixing frame, a connecting bolt, and a connecting nut. The fixing frame is fixedly mounted on the housing, the connecting bolt is connected to the fixing frame, and the connecting nut is threadedly connected to the connecting bolt. The fixing process of the housing is completed through the cooperation of each component.

[0018] Beneficial effects:

[0019] 1. The design of the unlocking component makes the fixing and unlocking process of the conduit simple and quick. Through the cooperation of the conduit, mounting plate, fixing tube, sliding ring, sliding rod and fixing sleeve, the operator can easily slide the sliding ring to compress the tension spring and move the sliding rod, thereby driving the moving plate and pushing block to complete the fixing of the conduit.

The setting of the cable clamping plate and cable clamping block further enhances the fixing effect of the cable conduit and improves the reliability of the device. This design makes the fixing process of the cable conduit simpler and helps to improve the convenience of operation and production efficiency.

[0021] 3. The mounting components, including the mounting bracket, connecting bolts, and connecting nuts, enable quick installation and disassembly of the cylindrical split-type Hall current sensor with external devices. The use of the iron core, primary coil, and magnetic steel sleeve ensures the efficient operation of the split-type Hall current sensor, while the bakelite cover and fixing bolts and nuts provide robust protection and fixation. This design not only simplifies the installation process of the split-type Hall current sensor but also improves overall performance and reliability, helps reduce the failure rate of external devices during startup, and enhances the user experience.

[0031] Please see Figure 1-5 A split-type Hall current sensor includes a housing 1. An unlocking assembly is provided on one side of the housing 1 via a wire-locking assembly. The unlocking assembly includes a conduit 2, a mounting plate 3, a fixing tube 4, a sliding ring 5, a sliding rod 6, and a fixing sleeve 7. The conduit 2 is connected to one side of the housing 1. The mounting plate 3 is located outside the conduit 2. The fixing tube 4 is fixedly mounted on the mounting plate 3. The sliding ring 5 is connected to the outside of the fixing tube 4. The sliding rod 6 is connected to the sliding ring 5. The fixing sleeve 7 is fixedly mounted on the fixing tube 4 and slidably connected to the sliding rod 6. The wire-locking assembly includes a moving groove 8, a moving plate 9, and a pushing groove 10. The moving groove 8 is formed on the fixing tube 4. The moving plate 9 is slidably connected to the moving groove 8 and connected to the sliding rod 6. The pushing groove 10 is formed inside the fixing tube 4. The housing 1 is provided with the mounting assembly.

[0032] A first tension spring 11 is provided between the movable plate 9 and the fixed tube 4. The first tension spring 11 is sleeved on the outside of the fixed sleeve 7 and the sliding rod 6.

[0033] A push block 12 is slidably connected to the push groove 10, and a spring 13 is connected to the push block 12.

[0034] A wire clamping plate 14 is connected to the spring 13, and wire clamping blocks 15 are evenly distributed on the wire clamping plate 14.

[0035] In this embodiment, when it is necessary to fix the conduit 2 during use, the conduit 2 is manually passed through one end of the fixing tube 4 and then led out from the other end of the fixing tube 4. During its introduction, the sliding ring 5 on the outside of the fixing tube 4 is manually slid. During the sliding movement of the sliding ring 5, the sliding rod 6 on the sliding ring 5 is driven to slide along the fixing sleeve 7 on the fixing tube 4. During its sliding movement, the first tension spring 11 between the moving plate 9 and the fixing tube 4 is compressed, thereby driving the moving plate 9 to slide along the moving groove 8. During the movement process, the push block 12 slides along the push groove 10. After the conduit 2 is placed into the fixed tube 4, the sliding ring 5 is released, allowing it to reset under the action of the first tension spring 11. This causes the sliding ring 5, sliding rod 6, and moving plate 9 to move to their initial positions. Under the action of the second tension spring, the push block 12 slides along the push groove 10 to its initial position. In conjunction with the spring 13, the wire clamping plate 14, and the wire clamping block 15, the conduit 2 is fixed, ensuring its stability during use and preventing it from moving arbitrarily.

[0036] Please see Figure 5 As an embodiment of a split-type Hall current sensor for mounting components: the mounting components include a fixing frame 16, a connecting bolt 17 and a connecting nut 18. The fixing frame 16 is fixedly mounted on the housing 1, the connecting bolt 17 is connected to the fixing frame 16, and the connecting nut 18 is threadedly connected to the connecting bolt 17.

[0037] One end of the housing 1 is detachably connected to a bakelite cover 19, and a protrusion 20 is connected to the bakelite cover 19. The conduit 2 is connected to one end of the housing 1, and a connector 21 is connected to one end of the conduit 2.

[0038] An iron core 22 is installed inside the housing 1, a primary coil 23 is wound around the outside of the iron core 22, and a magnetic steel sleeve 24 is installed at one end of the iron core 22.

[0039] A fixing bolt 25 is connected to the housing 1, the fixing bolt 25 passes through the bakelite cover 19, and a fixing nut 26 is threaded on the fixing bolt 25. A second tension spring 27 is connected between the push block 12 and the fixing tube 4. A bracket 28 is installed inside the housing 1.

[0040] More specifically, during use, the connecting nut 18 is manually removed from the connecting bolt 17, then the connecting bolt 17 is passed through the plate to be placed, and then the connecting nut 18 is rotated from one end of the connecting bolt 17, thereby completing the fixing process of the housing 1. During use, the iron core 22, primary coil 23 and magnetic steel sleeve 24 inside the housing 1 are used for relevant testing, and the bracket 27 is used to fix them. Then, the bakelite cover 19 is inserted through the fixing bolt 25 on the housing 1, and then the fixing nut 26 is used to fix the bakelite cover 19.

[0041] In summary, during the use or operation of the overall equipment: When it is necessary to fix the conduit 2 during use, the conduit 2 is manually passed through one end of the fixing pipe 4 and then led out from the other end of the fixing pipe 4. During its introduction, the sliding ring 5 on the outside of the fixing pipe 4 is manually slid. During the sliding movement of the sliding ring 5, the sliding rod 6 on the sliding ring 5 is driven to slide along the fixing sleeve 7 on the fixing pipe 4. During its sliding movement, the first tension spring 11 between the moving plate 9 and the fixing pipe 4 is compressed, thereby driving the moving plate 9 along the moving groove. 8. The sliding movement process is carried out, thereby driving the push block 12 to slide along the push groove 10. After the conduit 2 is placed into the fixed tube 4, the sliding ring 5 is released, so that it is reset under the action of the first tension spring 11. This causes the sliding ring 5, the sliding rod 6 and the moving plate 9 to move to the initial position. Then, under the action of the second tension spring, the push block 12 is driven to slide along the push groove 10 to the initial position. In conjunction with the spring 13, the wire clamping plate 14 and the wire clamping block 15, the process of fixing the conduit 2 is completed, so that it remains stable during use and does not move arbitrarily.

[0042] During use, the connecting nut 18 is manually removed from the connecting bolt 17, the connecting bolt 17 is then inserted through the plate to be placed, and the connecting nut 18 is rotated from one end of the connecting bolt 17 to complete the fixing process of the housing 1. During use, the iron core 22, primary coil 23 and magnetic steel sleeve 24 inside the housing 1 are used for relevant testing, and the bracket 27 is used to fix them. Then, the bakelite cover 19 is inserted through the fixing bolt 25 on the housing 1, and the fixing nut 26 is used to fix the bakelite cover 19.
