Description

Technical Field

[0001] This invention relates to the field of magnetic core inductor technology, and more particularly to a combined magnetic core inductor. Background Technology

[0002] Magnetic core inductors are commonly used on circuit boards of various electrical equipment. However, when assembling existing magnetic core inductors, the magnetic core is often fixed to the inductor frame with glue or tape. This not only makes the installation process cumbersome and time-consuming, but also makes it difficult for staff to disassemble and replace the magnetic core if it is damaged later, thus failing to achieve good performance. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined magnetic core inductor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a combined magnetic core inductor, comprising an inductor frame, pins mounted at the bottom of the inductor frame, a coil wound on the surface of the inductor frame, the coil being electrically connected to the pins, a connecting groove being formed inside the inductor frame, a limiting groove being formed on the surface of the inductor frame outside the connecting groove, a magnetic core body being inserted inside the connecting groove, the magnetic core body being slidably connected to the limiting groove, a limiting hook being rotatably connected on the surface of the inductor frame outside the magnetic core body, and a spring piece being fixedly mounted on the surface of the inductor frame outside the limiting hook.

[0005] To ensure the magnetic core body is fixed and stable, the present invention includes an improvement in which a limiting frame is fitted on the outer side of the magnetic core body, and a pull ring is fixedly mounted on the surface of the limiting frame.

[0006] To limit the position between the two sets of magnetic core bodies, the present invention includes an improvement in which side plates are fixedly mounted on the outer side of the limiting frame, and the side plates are symmetrically distributed.

[0007] To protect the inductor frame and the magnetic core body, the present invention includes an improvement in which a protective structure is provided on the outer side of the inductor frame. The protective structure includes a protective cover, which is fitted onto the surface of the inductor frame. A slider is fixedly installed inside the protective cover, and a protrusion is fixedly installed on the surface of the slider. A groove is formed on the surface of the inductor frame, and a recess is formed inside the groove. The slider is slidably connected to the groove.

[0008] To facilitate gripping the protective cover, the present invention includes an improvement in that the surface of the protective cover is fixedly fitted with anti-slip strips, which are distributed at equal intervals.

[0009] To limit the position of the magnetic core body, the present invention includes an improvement in which a limiting block is fixedly installed inside the protective cover, and the magnetic core body is slidably connected to the limiting block.

[0010] To make the magnetic core body more stable, the present invention includes an improvement in which a pressure block is fixedly installed on the inner side of the protective cover, and the pressure block is symmetrically distributed.

[0011] To facilitate the connection of the pins, the present invention includes an improvement in which a connection structure is provided at the bottom of the pins. The connection structure includes a disk, which is fixedly connected to the pins, and a metal hook is fixedly mounted at the bottom of the disk.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0013] 1. In this invention, by setting the limiting hook, the operator only needs to pick up the magnetic core body, insert the magnetic core body into the connecting groove of the inductor frame, and make the magnetic core body lock into the limiting groove. The spring can push the limiting hook to hook the magnetic core body, thereby fixing the magnetic core body and preventing it from being easily removed. The entire magnetic core inductor can then be used normally. When the magnetic core body is damaged and needs to be replaced, the operator only needs to rotate the limiting hook to separate the limiting hook from the magnetic core body, and then the damaged magnetic core body can be removed for replacement. The whole process is simple and quick to operate, convenient for operators to use, and can achieve good usage results.

[0014] 2. In this invention, by setting up this protective structure, the operator can pick up the protective cover, put the protective cover on the outside of the inductor frame, insert the slider into the groove, and then the protrusion can be locked into the groove to fix the protective cover. This allows the protective cover to protect the inductor frame and the magnetic core body, preventing the inductor frame and the magnetic core body from being easily damaged, so as to achieve better use effect.

[0015] 3. In this invention, by setting this connection structure, when installing and connecting the entire magnetic core inductor to the wiring hole on the circuit board, simply align the metal hook with the reserved wiring hole on the circuit board, and the metal hook itself will use its own deformation elasticity to hold the wiring hole and fix the pin, thus completing the pin connection. The whole process is simple and quick, making it convenient for staff to install and use. Attached Figure Description

[0026] Example 1

[0027] like Figure 1-6As shown, this invention provides a technical solution: a combined magnetic core inductor, including an inductor frame 1, pins 2 mounted on the bottom of the inductor frame 1, a coil 3 wound on the surface of the inductor frame 1, the coil 3 being electrically connected to the pins 2, a connecting groove being formed inside the inductor frame 1, and a limiting groove 4 being formed on the surface of the inductor frame 1 outside the connecting groove, a magnetic core body 5 being inserted inside the connecting groove, and the magnetic core body 5 being slidably connected to the limiting groove 4. The inductor frame 1, coil 3, magnetic core body 5, and pins 2 together constitute a common magnetic core inductor. Its specific working principle and usage are common technical knowledge to those skilled in the art, and therefore are not described in detail here. The surface of the inductor frame 1 is located outside the magnetic core body 5. The rotating connection has a limiting hook 6. A spring piece 7 is fixed to the surface of the inductor frame 1 outside the limiting hook 6. The operator simply needs to pick up the magnetic core body 5, insert it into the connecting groove of the inductor frame 1, and then lock the magnetic core body 5 into the limiting groove 4. The spring piece 7 can push the limiting hook 6 to hook the magnetic core body 5, thus fixing the magnetic core body 5 and preventing it from being easily removed. The entire magnetic core inductor can then be used normally. When the magnetic core body 5 is damaged and needs to be replaced, the operator simply rotates the limiting hook 6 to separate it from the magnetic core body 5, allowing the damaged magnetic core body 5 to be removed and replaced. The entire process is simple and quick, convenient for operators, and achieves good performance.

[0028] like Figure 1-6 As shown, a limiting frame 8 is sleeved on the outer side of the magnetic core body 5. The elastic force of the limiting frame 8 presses the magnetic core body 5 so that the magnetic core body 5 can be fixed more stably. A pull ring is fixed on the surface of the limiting frame 8, which allows the operator to easily pull the limiting frame 8 and remove it. A side plate 9 is fixed on the outer side of the limiting frame 8. The side plates 9 are symmetrically distributed and can limit the position of the magnetic core body 5 to prevent the two sets of magnetic core bodies 5 from being misaligned.

[0029] Example 2

[0030] like Figure 2-6 As shown, a protective structure is provided on the outside of the inductor frame 1. The protective structure includes a protective cover 10, which is fitted onto the surface of the inductor frame 1. A slider 11 is fixedly installed inside the protective cover 10, and a protrusion is fixedly installed on the surface of the slider 11. A groove 12 is opened on the surface of the inductor frame 1, and a recess 17 is opened inside the groove 12. The slider 11 is slidably connected to the groove 12. The operator can pick up the protective cover 10 and put it on the outside of the inductor frame 1, so that the slider 11 is inserted into the groove 12, and the protrusion is locked into the recess 17 to fix the protective cover 10. This allows the protective cover 10 to protect the inductor frame 1 and the magnetic core body 5, preventing the inductor frame 1 and the magnetic core body 5 from being easily damaged, so as to achieve better use effect.

[0031] like Figure 2-6 As shown, the protective cover 10 is fixedly equipped with anti-slip strips, which are evenly distributed. The anti-slip strips can increase the friction between the hand and the protective cover 10, so that the operator can hold the protective cover 10 stably. The protective cover 10 is fixedly equipped with a limiting block 13, and the magnetic core body 5 is slidably connected to the limiting block 13. The protective cover 10 is fixedly equipped with a pressing block 14, which is symmetrically distributed. The limiting block 13 can be locked on the outside of the magnetic core body 5, while the pressing block 14 can press down on the magnetic core body 5, so that the magnetic core body 5 can be more stable.

[0032] Example 3

[0033] like Figure 5 As shown, a connection structure is provided at the bottom of pin 2. The connection structure includes a disk 15, which is fixedly connected to pin 2. A metal hook 16 is fixedly installed at the bottom of the disk 15. When installing and connecting the entire magnetic core inductor to the wiring hole on the circuit board, simply align the metal hook 16 with the reserved wiring hole on the circuit board. The metal hook 16 can then lock the wiring hole through its own deformation and elasticity, thus fixing pin 2 and completing the connection of pin 2. The whole process is simple and quick, making it convenient for staff to install and use.

[0034] Working Principle: During assembly, the operator simply picks up the magnetic core body 5, inserts it into the connecting slot of the inductor frame 1, and locks it into the limiting slot 4. At this time, the spring piece 7 pushes the limiting hook 6 to hook the magnetic core body 5, thus fixing it in place and preventing it from being easily removed. The entire magnetic core inductor can then be used normally. The operator can also attach the limiting bracket 8 to the outside of the two sets of magnetic core bodies 5. The elasticity of the limiting bracket 8 compresses the magnetic core body 5, ensuring a more stable fixation. The side plate 9 restricts the position of the magnetic core bodies 5, preventing misalignment. When the magnetic core body 5 is damaged and needs replacement, the operator simply removes the limiting bracket 8 and rotates the limiting hook 6 to separate it from the magnetic core body 5, allowing the damaged magnetic core body 5 to be removed and replaced. The entire process is simple, quick, and convenient. When used by personnel, the protective cover 10 can be picked up by the staff. The anti-slip strip increases the friction between the hand and the protective cover 10, so that the staff can hold the protective cover 10 stably. Then, the protective cover 10 is fastened to the outside of the inductor frame 1, and the slider 11 is inserted into the slide groove 12, so that the protrusion is locked into the groove 17 to fix the protective cover 10. The protective cover 10 protects the inductor frame 1 and the magnetic core body 5, preventing the inductor frame 1 and the magnetic core body 5 from being easily damaged. The limiting block 13 can be locked on the outside of the magnetic core body 5, and the pressure block 14 can press down on the magnetic core body 5, so that the magnetic core body 5 can be more stable. When installing and connecting the entire magnetic core inductor to the wiring hole on the circuit board, simply align the metal hook 16 with the reserved wiring hole on the circuit board, and the deformation elasticity of the metal hook 16 can lock the wiring hole and fix the pin 2, so that the entire magnetic core inductor can be used normally.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields.
