Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, specifically to a continuous positioning structure for a fixed integrally formed inductor coil. Background Technology

[0002] An inductor coil is an inductor specifically designed for high-frequency environments. It features a simple structure and excellent performance, with various wire specifications to flexibly adapt to diverse design needs, making it a crucial component in inductor molding technology. Molded inductors, in particular, are made by winding coils with round copper wire and then die-casting them with iron powder using a special process, exhibiting excellent characteristics such as high current resistance and low impedance, and are widely used in various high-current electronic circuits. In the manufacturing process, multiple inductor coils are spot-welded to a frame, followed by die-casting of magnetic powder to form a magnetic core, and then further processing through shearing, bending, and other steps to complete the molding process.

[0003] In existing technologies, the industry commonly uses resistance spot welding, laser spot welding, or ultrasonic spot welding to fix individual inductor coils to a metal frame. Subsequent processes such as core die casting, frame cutting, and bending complete the final shape. This process relies primarily on sampling inspection to assess weld strength. However, this sampling method cannot cover all products, making the welded areas prone to quality defects. If the weld quality is substandard, potentially defective products may flow into subsequent processes, posing a serious threat to overall product quality and increasing uncertainty and risk in the production process.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a continuous positioning structure for fixing an integrally molded inductor coil, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a continuous positioning structure for fixing an integrally molded inductor coil, including two mounting frames. Multiple electrode plates are connected to one side of each mounting frame opposite to the other. A fixing plate is fixedly connected to the top of the side of each electrode plate away from the mounting frame. A fixing block is fixedly connected to the top of the fixing plate. A first clamp and a second clamp are rotatably connected to the inner wall of the fixing block. Mounting plates are fixedly connected to the outer walls of the first clamp and the second clamp away from each other. Springs are connected to the bottom ends of the two mounting plates. Coil leads are abutted to the inner walls of the first clamp and the second clamp.

[0007] Furthermore, a magnetic core is installed on the opposite side of the two coil pins, and the outer wall of the magnetic core is fixedly connected to the two coil pins.

[0008] Furthermore, multiple connecting rods are installed on one side of the two mounting frames facing each other, and the two ends of the connecting rods are fixedly connected to the mounting frames.

[0009] Furthermore, each mounting frame has multiple bends, and the mounting position of each bend is located on the side away from the magnetic core from the centerline of the positioning hole.

[0010] Furthermore, the first clamp and the second clamp are rotatably connected, one end of the spring is fixedly connected to the mounting plate, and the other end of the spring is fixedly connected to the fixing plate.

[0011] Furthermore, each mounting frame has multiple positioning holes on its outer wall, the diameter of which is smaller than the width of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using a locking component to fix the coil pins with pre-clamping force and structural fitting, the inductor coil is fixed to the mounting frame. This eliminates the need for spot welding, achieves mechanical locking, ensures stable coil position during die casting, avoids inductance fluctuations caused by magnetic circuit asymmetry during core forming, and prevents loosening of the inductor coil due to weak welding connections in the future.

[0014] The use of mechanical locking simplifies the production process, reduces production steps, and improves production efficiency. This significantly shortens the production time of a single product, reduces equipment dependence, eliminates the need for high-precision welding equipment, and reduces equipment procurement and maintenance costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a continuous positioning structure for fixing an integrally molded inductor coil, including two mounting frames 1, which are arranged in parallel to each other to form the supporting body of the integrally molded inductor. The frames are fixedly connected internally by connecting rods 11 to form a stable mechanical structure. Multiple electrode plates 2 are connected to opposite sides of the two mounting frames 1. Each electrode plate 2 has a fixing plate 3 fixedly connected to its top end on the side away from the mounting frame 1. The electrode plates 2 are fixed to the opposite inner side of the mounting frames 1 for connecting the coil pins 9 of the inductor coil to achieve electrical conduction. A fixing block 4 is fixedly connected to the top end of the fixing plate 3. The fixing plate 3 is vertically fixed to the top end of the electrode plate 2 to support the fixing block 4. A first clamp 5 and a second clamp 6 are rotatably connected to the inner wall of the fixing block 4. Mounting plates 7 are fixedly connected to the outer walls of the first clamp 5 and the second clamp 6 on the side away from each other. A spring 8 is connected to the bottom end. The inner walls of the first clamp 5 and the second clamp 6 are connected to the coil pin 9. The first clamp 5 and the second clamp 6 are connected by rotation to form a symmetrical clamping structure, allowing the first clamp 5 and the second clamp 6 to open and close flexibly and stably around the inner wall of the fixing block 4. When the coil pin 9 needs to be installed, the first clamp 5 and the second clamp 6 rotate around the axis of the fixing block 4 under the action of external force to form an opening, which facilitates the insertion of the coil pin 9. After the external force is removed, the first clamp 5 and the second clamp 6 automatically close under the elastic restoring force of the spring 8 to clamp the coil pin 9. Due to the symmetry of the first clamp 5 and the second clamp 6, they can apply clamping force evenly, ensuring that the coil pin 9 will not shift or loosen during installation, simplifying the installation process, improving the stability and reliability of clamping, and making the fixing of the inductor coil more secure and precise.

[0023] See Figure 3A magnetic core 10 is installed on one side opposite to the two coil pins 9. The outer wall of the magnetic core 10 is fixedly connected to the two coil pins 9. The two coil pins 9 are located on both sides of the mounting frame 1 and are connected to the mounting frame 1 through the electrode plate 2 to achieve electrical conduction. The magnetic core 10 constitutes the magnetic circuit part of the integrally molded inductor. The magnetic core 10 is close to the inner side of the coil pins 9 to ensure the integrity and consistency of the circuit.

[0024] participate Figure 1 , Figure 2 Multiple connecting rods 11 are installed on one side of the two mounting frames 1 facing each other. The two ends of the connecting rods 11 are fixedly connected to the mounting frames 1. The interior of the mounting frames 1 is fixedly connected by the connecting rods 11 to form a stable mechanical structure and enhance the overall rigidity. The connecting rods 11 provide support when the mounting frames 1 are subjected to external forces to prevent the mounting frames 1 from deforming or shifting. The distribution density and length of the connecting rods 11 can be adjusted according to the size of the inductor and the force requirements.

[0025] See Figure 1 , Figure 2 Each mounting frame 1 has multiple positioning holes 12 on its outer wall. The diameter of the positioning holes 12 is smaller than the width of the mounting frame 1 to ensure that they do not penetrate the entire wall thickness of the mounting frame 1. They are used only as local positioning or fixing points. The positioning holes 12 serve as static references during assembly to ensure assembly accuracy, prevent the mounting frame 1 from shifting or loosening during use, and improve the stability of the overall structure.

[0026] See Figure 2 Each mounting frame 1 has multiple bends 13. The mounting position of each bend 13 is located on the side away from the magnetic core 10 from the center line of the positioning hole 12. During the die casting process, the bend 13 serves as a positioning reference to guide the die casting mold to be precisely aligned with the mounting frame 1, which facilitates positioning during die casting and cutting.

[0027] Working principle: The main body of the integrally molded inductor is formed by two parallel mounting frames 1. The frame is fixedly connected by connecting rods 11 to enhance rigidity. The electrode plate 2 is fixed to the inside of the mounting frame 1. The top is supported by the first clamp 5 and the second clamp 6 symmetrically by the fixing plate 3 and the fixing block 4. When the coil pin 9 is inserted into the first clamp 5 and the second clamp 6, the clamp rotates around the fixing block 4 to form an opening. After the external force is removed, the spring 8 drives the clamp to close, evenly clamping the coil pin 9 to ensure stable electrical connection. The magnetic core 10 is fixed to the opposite side of the two coil pins 9, close to the inside of the pin to ensure the integrity of the magnetic circuit. The positioning hole 12 and the bending opening 13 are used for assembly positioning and die casting and cutting process positioning, respectively, to improve the structural accuracy and reliability.

[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
