Description

Technical Field

[0001] This utility model relates to the field of magnetic core protection technology, and in particular to a magnetic core with protective function. Background Technology

[0002] Magnetic cores are the core components in electronic devices used to concentrate and guide magnetic flux. They are mainly made of magnetic materials with high permeability and play a key role in electromagnetic components such as inductors, transformers, and instrument transformers. With the current trend of miniaturization and high frequency in electronic devices, magnetic cores are susceptible to physical damage. When a magnetic core is subjected to external mechanical impact, the impact force acts directly on the core body, which can easily cause damage to the internal structure of the core, affect the performance of the core, and even cause the core to become unusable.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the magnetic core body is affected by environmental factors such as mechanical impact, collision, and wear, it may be damaged, resulting in the magnetic core body being unable to be used normally; therefore, a magnetic core with protective function is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the magnetic core body is damaged by environmental factors such as mechanical impact, collision, and wear, resulting in the magnetic core body being unable to function properly. Therefore, this invention proposes a magnetic core with protective functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic core with protective function, comprising a magnetic core body, a fixed frame slidably connected to the surface of the magnetic core body, a sliding frame slidably connected to the surface of the fixed frame, a rotating rod rotatably connected to the surface of the sliding frame, and a protective plate fixedly connected to the arc surface of the rotating rod.

[0006] The aforementioned components achieve the following effect: they protect the magnetic core body from environmental factors such as mechanical impact, collision, and wear, preventing damage to the magnetic core body and thus preventing it from being used normally, thereby improving the safety of the equipment.

[0007] Preferably, a connecting plate is fixedly connected to the surface of the sliding frame, a rod is slidably inserted into the connecting plate, and a plurality of slots are provided on the surface of the fixed frame.

[0008] The aforementioned components achieve the following effect: they facilitate the adjustment of the sliding frame by the staff, thereby enabling the protective plate to protect magnetic core bodies of different lengths and making it easy to adapt to magnetic core bodies of different lengths.

[0009] Preferably, one end of the insertion rod has a groove, and an operating block is fixedly connected to the surface of the groove.

[0010] The effect achieved by the above components is that the operating block makes it easier for the staff to pull the plug rod, and avoids the situation where the staff's hands slip when pulling the plug rod because the arc surface of the plug rod is relatively smooth.

[0011] Preferably, the surface of the connecting plate is provided with a groove, and a blocking block is slidably connected to the surface of the groove.

[0012] The effect achieved by the above-mentioned components is to restrict the movement of the insertion rod, thereby preventing the insertion rod from colliding with the slot of the fixed frame when the operator moves the sliding frame, which would damage the insertion rod and cause it to malfunction.

[0013] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the operating block and the connecting plate, respectively.

[0014] The effect achieved by the above components is that the spring's rebound force automatically inserts the insertion rod, while also restricting the rod's movement and improving the stability of the rod when it is in position.

[0015] Preferably, the surface of the sliding frame has two sliding grooves, and an L-shaped plate is slidably connected to the surface of the sliding grooves.

[0016] The aforementioned components achieve the following effect: they can fix the protective plate in place, preventing the protective plate from opening automatically when the magnetic core body is subjected to mechanical impact, thus avoiding a reduction in the protective effect of the protective plate.

[0017] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the sliding frame and the protective plate, respectively.

[0018] The effect achieved by the above components is that the torsion spring's torque automatically opens the protective plate while keeping it open, thus facilitating the removal of the magnetic core body from the fixed frame by the staff.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model achieves the effect of protecting the magnetic core body, avoiding damage to the magnetic core body caused by environmental factors such as mechanical impact, collision, and wear, thus preventing the magnetic core body from being used normally and improving the safety of the equipment.

[0028] Reference Figures 1-6As shown, this utility model provides a technical solution: a magnetic core with protective function, including a magnetic core body 1, a fixed frame 2 slidably connected to the surface of the magnetic core body 1, a sliding frame 3 slidably connected to the surface of the fixed frame 2, a rotating rod 4 rotatably connected to the surface of the sliding frame 3, and a protective plate 5 fixedly connected to the arc surface of the rotating rod 4, achieving the effect of protecting the magnetic core body 1, avoiding damage to the magnetic core body 1 caused by environmental factors such as mechanical impact, collision, and wear, and preventing the magnetic core body 1 from being used normally, thus improving the safety of the equipment. A connecting plate 6 is fixedly connected to the surface of the sliding frame 3, and a plug rod 7 is slidably inserted into the connecting plate 6. Several slots are opened on the surface of the fixed frame 2. Due to the magnetic core body 1... With varying lengths, when the magnetic core body 1 is longer, the sliding frame 3 can be adjusted, and the insertion rod 7 can be pulled. The insertion rod 7 slides within the connecting plate 6. When the insertion rod 7 is completely disengaged from the surface of the slot in the fixed frame 2, the insertion rod 7 releases its fixation on the sliding frame 3. The sliding frame 3 is then moved, sliding on the surface of the fixed frame 2. When the sliding frame 3 moves to the appropriate position, the insertion rod 7 is pushed. When the insertion rod 7 is inserted into the surface of the slot in the fixed frame 2, the insertion rod 7 fixes the sliding frame 3. The protective plate 5 is then rotated, causing the rotating rod 4 to rotate until the protective plate 5 rotates to the surface of the magnetic core body 1. At this point, the protective plate 5 protects the magnetic core body 1, achieving the effect of facilitating the adjustment of the sliding frame 3 by the operator. This allows the protective plate 5 to be used for magnetic core bodies 1 of different lengths. For protection and easy adaptation to magnetic core bodies 1 of different lengths, one end of the insertion rod 7 has a groove. An operating block 8 is fixedly connected to the surface of the groove of the insertion rod 7. When the operator needs to move the sliding frame 3, he pulls the operating block 8, which moves the insertion rod 7 until the insertion rod 7 is completely disengaged from the surface of the slot of the sliding frame 3. At this time, the operator can move the sliding frame 3. The operating block 8 achieves the effect of making it convenient for the operator to pull the insertion rod 7, avoiding the situation where the operator's hand slips when pulling the insertion rod 7 due to the relatively smooth arc surface of the insertion rod 7. The surface of the connecting plate 6 has a sliding groove 13, and a blocking block 9 is slidably connected to the surface of the sliding groove 13. When the operator moves the sliding frame 3, he pulls the operating block 8, which moves the insertion rod 7. When the insertion rod 7 is released from its fixation to the sliding frame 3, the moving blocking block 9 slides on the surface of the slide groove 13. When the blocking block 9 moves between the operating block 8 and the connecting plate 6, it fixes the operating block 8. At this time, the blocking block 9 can indirectly fix the insertion rod 7, allowing the operator to move the sliding frame 3. This achieves the effect of restricting the movement of the insertion rod 7, preventing the insertion rod 7 from colliding with the slot of the fixed frame 2 when the operator moves the sliding frame 3, which could damage the insertion rod 7 and cause it to malfunction. The arc surface of the insertion rod 7 is fitted with a spring 10, and the two ends of the spring 10 are fixedly connected to the operating block 8 and the connecting plate 6, respectively. When the operator pulls the operating block 8, the spring 10 is stretched, and the operating block 8 drives the insertion rod 7 to move.When the insertion rod 7 releases its fixation on the sliding frame 3, the moving blocking block 9 fixes the operating block 8. At this time, the operator can move the sliding frame 3. When the operator moves the sliding frame 3 to the appropriate position, the blocking block 9 is moved until it no longer restricts the movement of the operating block 8. The rebound force of the spring 10 drives the operating block 8 to move, and the operating block 8 drives the insertion rod 7 to move until the insertion rod 7 is inserted into the surface of the slot of the fixed frame 2. The rebound force of the spring 10 achieves the effect of automatically inserting the insertion rod 7, while restricting the movement of the insertion rod 7, thus improving the stability of the insertion rod 7 when it is in the limit position. The surface of the sliding frame 3 has two sliding grooves, and an L-shaped plate 11 is slidably connected to the surface of the sliding groove of the sliding frame 3. When the operator needs to rotate the protective plate 5 to the surface of the magnetic core body 1, the protective plate 5 is rotated. The protective plate 5 drives the rotating rod 4 to rotate. When the protective plate 5 rotates to the surface of the magnetic core body 1, the L-shaped plate 11 is moved. The L-shaped plate 11 slides on the surface of the sliding groove of the sliding frame 3. When the L-shaped plate 11 moves to the surface of the protective plate 2, the L-shaped plate 11 is moved. When the surface is 5, the L-shaped plate 11 fixes the protective plate 5, achieving the effect of securing the protective plate 5. This prevents the protective plate 5 from automatically opening when the magnetic core body 1 is subjected to mechanical impact, thus avoiding a reduction in the protective effect of the protective plate 5. Two torsion springs 12 are fitted on the arc surface of the rotating rod 4. The two ends of the torsion springs 12 are fixedly connected to the sliding frame 3 and the protective plate 5, respectively. When the operator needs to open the protective plate 5, the L-shaped plate 11 is moved. When the L-shaped plate 11 is completely detached from the surface of the protective plate 5, the L-shaped plate 11 releases its fixation on the protective plate 5. The torque of the torsion springs 12 drives the protective plate 5 to rotate, which in turn drives the rotating rod 4 to rotate until the protective plate 5 is fully open. At this point, the operator can hold the fixing frame 2 with one hand and move the magnetic core body 1 with the other to remove the magnetic core body 1 from the fixing frame 2. The torque of the torsion springs 12 achieves the effect of automatically opening the protective plate 5 while keeping it open, thus facilitating the operator to remove the magnetic core body 1 from the fixing frame 2.

[0029] Working principle: Due to varying lengths of the magnetic core body 1, when the magnetic core body 1 is longer, the sliding frame 3 can be adjusted. Pulling the operating block 8 stretches the spring 10, causing the operating block 8 to move the insertion rod 7. The insertion rod 7 slides within the connecting plate 6. When the insertion rod 7 completely disengages from the surface of the slot in the fixed frame 2, the insertion rod 7 releases its fixation to the sliding frame 3, allowing the movement of the blocking block 9. The blocking block 9 slides on the surface of the slide groove 13. When the blocking block 9 moves between the operating block 8 and the connecting plate 6, it fixes the operating block 8. At this point, the blocking block 9 can indirectly fix the insertion rod 7. The operator can then move the sliding frame 3, which slides on the surface of the fixed frame 2. When the sliding frame 3 moves to the appropriate position, the blocking block 9 is moved until it no longer restricts the movement of the operating block 8. At this point, the blocking block 9 releases its fixation to the operating block 8, and the spring 10's rebound force moves the operating block 8. The operating block 8 then moves the insertion rod 7 until it is inserted into the surface of the slot in the fixed frame 2, fixing the sliding frame 3. Rotate the protective plate 5, which drives the rotating rod 4 to rotate until the protective plate 5 rotates to the surface of the magnetic core body 1. Move the L-shaped plate 11, which slides on the surface of the sliding groove of the sliding frame 3. When the L-shaped plate 11 moves to the surface of the protective plate 5, it fixes the protective plate 5. When the operator needs to remove the magnetic core body 1 from the fixed frame 2, move the L-shaped plate 11. When the L-shaped plate 11 is completely detached from the surface of the protective plate 5, it releases the fixation of the protective plate 5. The torque of the torsion spring 12 drives the protective plate 5 to rotate, which drives the rotating rod 4 to rotate until the protective plate 5 is fully opened. At this time, the operator can hold the fixed frame 2 with one hand and move the magnetic core body 1 with the other hand to remove the magnetic core body 1 from the fixed frame 2. This achieves the effect of protecting the magnetic core body 1, avoiding the magnetic core body 1 from being damaged by environmental factors such as mechanical impact, collision, and wear, which would cause the magnetic core body 1 to be unusable.
