Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil technology, specifically to an electromagnetic coil. Background Technology

[0002] An electromagnetic coil is a core component made of wound wire. It generates a magnetic field through the flow of electric current, enabling the conversion between electrical and magnetic energy. Its working principle is based on Ampere's circuital law; when current flows through the coil, a concentrated magnetic field is formed inside. Inserting an iron core significantly enhances the magnetic flux. Electromagnetic coils are widely used in electromagnets, relays, transformers, wireless charging, and sensors, driving mechanical motion, controlling circuit switching, and also for voltage conversion and energy transfer.

[0003] In the prior art, for example, Chinese utility model patent (authorization announcement number CN221946895U) discloses a waterproof electromagnetic coil with an improved structure, which includes a frame, a coil and a shell. The coil is sleeved on the frame, and the frame is located inside the shell. An embedding groove is provided at the upper end of the shell. The frame is slidably fixed inside the shell through the embedding groove. A pressure block is provided in the embedding groove. The pressure block installs and fixes the frame inside the shell. A locking member is provided between the pressure block and the embedding groove. The locking member fixes the pressure block in the embedding groove.

[0004] The electromagnetic coils disclosed in the prior art, by incorporating a plug on the outer casing, require users to spend time confirming the insertion direction, especially in space-constrained or frequently plugged-in scenarios. This inconvenience can easily lead to connection failure or plug damage due to misinsertion. Furthermore, traditional plug designs are mostly single-function, supporting only power transmission or low-speed data transmission, which is insufficient to meet the multi-functional integration requirements of electromagnetic coils in complex application scenarios. Therefore, an electromagnetic coil is proposed. Utility Model Content

[0005] To address the aforementioned issues, an electromagnetic coil is provided. By using a first and a second outer shell to fix the Type-C plug, the installation direction of the electromagnetic coil can be adjusted. The Type-C plug enables both power supply and fast data transmission, solving the problems of not being able to adjust the installation direction of the electromagnetic coil and the plug only supporting power transmission or low-speed data transmission.

[0006] To address the problems of the prior art, this application provides an electromagnetic coil, including a package body, a magnetic guiding mechanism disposed inside the package body, a plastic skeleton disposed within the magnetic guiding mechanism, and a type-c plug mounted on the top of the package body. The package body includes a first outer shell, a second outer shell fixed to one side of the first outer shell, and mounting slots for mounting the type-c plug are provided on the top of the corresponding sides of the first and second outer shells. The Type-C plug is used for quick connection to an external controller, and two electrode plates are fixed on one side of the bottom of the Type-C plug. The plastic frame includes a coil winding column installed longitudinally inside the magnetic guiding mechanism. A coil is wound around the outside of the coil winding column. A first base is fixed to the bottom of the coil winding column. Two sets of elastic pins that can rebound are installed on one side of the first base. The two ends of the coil are electrically connected to the two sets of elastic pins respectively. A conductive plate is fixed on one side of the first housing. There are two sets of conductive plates. One side of the bottom of the conductive plate is in contact with the end of the elastic pin. The end of the conductive plate away from the elastic pin has a hook-shaped structure and is in contact with the electrode plate.

[0007] As one technical solution of this application, a U-shaped spring is fixed on one side of the conductive plate, and the side of the U-shaped spring away from the conductive plate is fixedly connected to the side of the hook-shaped structure.

[0008] As one technical solution of this application, a limiting groove is formed on one side of the type-c plug; A first limiting block that can be adapted to the limiting groove is fixed on one side of the second housing.

[0009] As a technical solution of this application, the bottom of the first shell is provided with an installation chamber for installing a magnetic guiding mechanism, and the bottom of the installation chamber is symmetrically fixed with a second limiting block for limiting the magnetic guiding mechanism. The magnetic guiding mechanism includes a bracket, a second base is installed at the bottom of the bracket, the second base is fixed to the bottom of the encapsulation body, and a second slot is provided on both sides of the second base to be adapted to the second limiting block.

[0010] As one technical solution of this application, a limiting hole is formed at the bottom of the first base; The upper surface of the second base is fixed with a limiting protrusion that can be adapted to the limiting hole.

[0011] As one technical solution of this application, the bottom end of the bracket is fixed with a third limiting block that can be inserted into the second slot; The first base has a first slot on one side that can be locked onto the outside of the third limiting block.

[0012] The advantages of this utility model compared to the prior art are: 1. This application uses a first and second outer shell to fix the Type-C plug, enabling adjustable installation direction of the electromagnetic coil. The Type-C plug allows for both power supply and high-speed data transmission. This solves the problems of not being able to adjust the installation direction of the electromagnetic coil and the plug only supporting power transmission or low-speed data transmission.

[0013] 2. This application provides a hook-shaped structure on the top of the conductive plate and then fixes a U-shaped spring between the hook-shaped structure and the conductive plate. This allows the U-shaped spring to push the hook-shaped structure closer to the electrode plate, ensuring that the hook-shaped structure is always in contact with the electrode plate. This effectively avoids the problem of the Type-C plug easily detaching from the conductive plate and causing poor contact due to repeated disassembly and reassembly. Attached Figure Description

Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. See Figures 1-8 As shown, an electromagnetic coil includes a package body 1, a magnetic guiding mechanism 5 disposed inside the package body 1, a plastic skeleton 4 disposed inside the magnetic guiding mechanism 5, and a type-c plug 2 installed on the top of the package body 1. The package body 1 includes a first outer shell 11, and a second outer shell 12 is fixed to one side of the first outer shell 11. The top of the corresponding side of the first outer shell 11 and the second outer shell 12 are both provided with mounting grooves for installing the type-c plug 2. The Type-C plug 2 is used for quick connection to an external controller. Two electrode plates 22 are fixed on one side of the bottom of the Type-C plug 2. The plastic frame 4 includes a coil winding post 41 that is longitudinally installed inside the magnetic guiding mechanism 5. A coil is wound around the outside of the coil winding post 41. A first base 42 is fixed to the bottom of the coil winding post 41. Two sets of elastic pins 43 that can rebound are installed on one side of the first base 42. The two ends of the coil are electrically connected to the two sets of elastic pins 43 respectively. A conductive plate 6 is fixed on one side of the first outer casing 11. There are two sets of conductive plates 6. One side of the bottom of the conductive plate 6 is in contact with the end of the elastic pin 43. The end of the conductive plate 6 away from the elastic pin 43 has a hook-shaped structure and is in contact with the electrode plate 22.

[0024] The Type-C plug 2 is fixed by the cooperation of the first outer shell 11 and the second outer shell 12, making the installation direction of the electromagnetic coil adjustable. The Type-C plug 2 enables both power supply and high-speed data transmission. This solves the problems of not being able to adjust the installation direction of the electromagnetic coil and the plug only supporting power transmission or low-speed data transmission. Then, two sets of electrode plates 22 are fixed to the Type-C plug 2, and a conductive plate 6 is fixed to one side of the first outer shell 11. The conductive plate 6 is electrically connected to the Type-C plug 2 through the electrode plates 22, and the bottom of the conductive plate 6 is electrically connected to the winding on the coil winding post 41 through elastic pins 43. This creates a circuit between the conductive plate 6 of the Type-C plug 2 and the plastic frame 4, thereby generating a magnetic field around the electromagnetic coil.

[0025] See Figure 8 As shown, a U-shaped spring 62 is fixed to one side of the conductive plate 6, and the side of the U-shaped spring 62 away from the conductive plate 6 is fixedly connected to the side of the hook-shaped structure.

[0026] To ensure that the conductive plate 6 is always in contact with the electrode plate 22, a hook-shaped structure is provided on the top of the conductive plate 6, and a U-shaped spring 62 is fixed between the hook-shaped structure and the conductive plate 6. This allows the U-shaped spring 62 to push the hook-shaped structure closer to the electrode plate 22, ensuring that the hook-shaped structure is always in contact with the electrode plate 22. This effectively avoids the type-c plug 2 from easily detaching from the conductive plate 6 and causing poor contact due to repeated disassembly and reassembly.

[0027] See Figure 3 and Figure 4 As shown, a limiting groove 21 is provided on one side of the type-c plug 2; A first limiting block 121 that can be adapted to the limiting groove 21 is fixed on one side of the second outer shell 12.

[0028] By opening a limiting groove 21 on one side of the type-c plug 2, when the second housing 12 is combined with the first housing 11, the first limiting block 121 on the second housing 12 will be inserted into the limiting groove 21, so that the first limiting block 121 and the limiting groove 21 cooperate to fix the type-c plug 2, effectively preventing the type-c plug 2 from falling off the encapsulation body 1.

[0029] See Figure 2 , Figure 6 and Figure 7 As shown, the bottom of the first outer shell 11 is provided with a mounting chamber 13 for mounting the magnetic guiding mechanism 5, and the bottom of the mounting chamber 13 is symmetrically fixed with a second limiting block 14 for limiting the magnetic guiding mechanism 5. The magnetic guiding mechanism 5 includes a bracket 51, and a second base 52 is installed at the bottom of the bracket 51. The second base 52 is fixed to the bottom of the encapsulation body 1. The second base 52 has a second slot 521 on both sides that can be adapted to the second limiting block 14.

[0030] To facilitate rapid installation of the magnetic guiding mechanism 5, the entire mechanism 5 is placed inside the mounting chamber 13. Second slots 521 are created on both sides of the second base 52, and these slots 521 are engaged with the second limiting block 14. This engagement of the second limiting block 14 and the second slots 521 restricts the entire magnetic guiding mechanism 5, thus positioning it. The second base 52 is then fixed to the first outer casing 11, effectively ensuring the stability of the magnetic guiding mechanism 5.

[0031] See Figure 6 and Figure 7 As shown, a limiting hole 421 is provided at the bottom of the first base 42; The upper surface of the second base 52 is fixed with a limiting protrusion 522 that can be adapted to the limiting hole 421.

[0032] A limiting protrusion 522 is fixed to the upper end face of the second base 52, and a limiting hole 421 is opened at the bottom of the first base 42. When the plastic frame 4 is installed inside the magnetic guiding mechanism 5, the limiting protrusion 522 will be inserted into the limiting hole 421, and the limiting hole 421 and the limiting protrusion 522 will cooperate to position the coil winding post 41.

[0033] See Figure 6 and Figure 7 As shown, a third limiting block 511 that can be inserted into the second slot 521 is fixed at the bottom end of the bracket 51; The first base 42 has a first slot 422 on one side that can be locked onto the outside of the third limiting block 511.

[0034] The bottom end of the third limiting block 511 is inserted into the second slot 521. At this time, the bracket 51 and the second base 52 cooperate to fix the first base 42, effectively preventing the first base 42 from moving longitudinally. To prevent the coil winding post 41 from rotating axially, a first slot 422 is opened on one side of the first base 42. Then, the first slot 422 is snapped onto the outside of the third limiting block 511. The cooperation between the first slot 422 and the third limiting block 511 limits the coil winding post 41, effectively preventing the coil winding post 41 from rotating axially, thereby improving the stability of the coil winding post 41.

[0035] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
