Description

Technical Field

[0001] This utility model relates to the field of common mode inductor technology, specifically to a transverse U-shaped common mode inductor component. Background Technology

[0002] A common-mode inductor is an electronic component used to suppress common-mode noise on power lines or signal lines; it is also called a common-mode choke. Through a symmetrically wound dual-coil structure, it presents high impedance to common-mode interference signals, effectively filtering out electromagnetic interference while allowing differential-mode signals to pass through without attenuation. Its structure consists of two coils with the same number of turns and size symmetrically wound on the same ferrite core, forming a four-terminal device. The core material is typically ferrite or amorphous to achieve efficient filtering at high frequencies. It is used in multi-stage filter circuits to enhance anti-interference capabilities.

[0003] Based on this, a search on the patent website revealed that Chinese patent application number CN201820958062.7 discloses a common mode inductor;

[0004] It is evident that the aforementioned patent applications have shortcomings: existing common-mode inductors, due to the limitations of the common-mode material properties of their magnetic rings and the absence of an air gap, cause the current to saturate prematurely, and they are also very large in size. The magnetic rings require a shuttle winding or manual threading process, which leads to complex manufacturing processes. In addition, they require a dedicated base, resulting in high overall costs.

[0005] To address the aforementioned issues, a transverse U-shaped common-mode inductor component is proposed. Utility Model Content

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a transverse U-shaped common mode inductor assembly. By using this device, the problems of existing common mode inductors, which are limited by the characteristics of the common mode material of the magnetic ring and the lack of air gap, result in premature current saturation, large size, and complex manufacturing process due to the need for shuttle winding or manual hooking of the magnetic ring. In addition, they require a special base and have a high overall cost.

[0007] The purpose of this utility model is achieved through the following technical solution: a transverse U-shaped common mode inductor assembly, including an iron core body and a winding frame disposed on the top of the iron core body, the winding frame being provided with two sets of coil windings, a bridging tape being fixedly connected to one side of the winding frame, an iron clamp body being disposed on one side of the winding frame, and protrusions being fixedly connected to both the left and right sides of the winding frame, the protrusions being provided in two sets.

[0008] Preferably, the iron clamp body is disposed on one side of the bridge tape, and a contact block is fixedly connected to the bottom of the winding skeleton.

[0009] By adopting the above-described structure and setting the winding frame, the heat accumulation effect can be suppressed, and the device life can be extended.

[0010] Preferably, a sealing ring is fixedly connected to the outer side of the contact block, and multiple sets of the sealing ring are provided.

[0011] The above-described structure, through the setting of the sealing ring, allows the winding frame to be stably connected to the iron core body.

[0012] Preferably, the top of the iron core body is provided with a contact groove, and multiple sets of the contact groove and the contact block are provided.

[0013] The above-described structure, through the design of contact grooves and contact blocks, enables workers to easily replace damaged parts.

[0014] Preferably, the contact groove slides with the contact block, and a groove is provided on the inner side of the iron clamp body.

[0015] The above-described structure, with its grooves, allows the clamp body to be installed more quickly on one side of the winding frame.

[0016] Preferably, multiple sets of grooves are provided, and the grooves slide in engagement with the protrusions.

[0017] The design of the above structure, with its grooves and protrusions, allows workers to remove and replace damaged metal clamps.

[0018] Preferably, friction blocks two are fixedly connected to both the upper and lower sides of the protrusion, and friction blocks one are fixedly connected to the groove, with friction blocks one and friction blocks two matching each other.

[0019] With the above-mentioned structural design, the setting of friction block one and friction block two ensures that the iron clamp body will not easily fall off from one side of the winding frame.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This application proposes a transverse U-shaped common-mode inductor assembly, which solves the problems of existing common-mode inductors, such as premature current saturation due to the limitations of the common-mode material characteristics of the magnetic ring and the absence of an air gap. Furthermore, these inductors are bulky, require complex manufacturing processes (such as shuttle winding or manual threading), and necessitate a dedicated base, resulting in high overall costs. By adjusting the magnetic circuit direction through a transverse U-shaped magnetic core on the winding frame, a more uniform magnetic flux density distribution can be achieved, reducing the risk of local magnetic saturation. Its horizontal symmetry design enhances the closure of the magnetic circuit, reduces leakage flux, and thus improves magnetic coupling efficiency. The transverse arrangement of two sets of windings on the winding frame significantly improves the core's anti-tipping capability. The wider winding window of the transverse U-shaped structure allows for the winding of larger diameter wires, enhancing current resistance and reducing copper losses. In contrast, the vertical U-shape, limited by height, may lead to increased winding density, affecting heat dissipation and current carrying capacity. The transverse arrangement, with its larger surface area and shorter heat dissipation path, effectively reduces the core temperature rise. Its loss characteristics are negatively correlated with temperature. Combined with the optimized air gap design, the heat accumulation effect can be suppressed and the device life can be extended. The vertical U-shaped structure may cause heat concentration due to the vertical stacking structure, requiring additional heat dissipation measures. Therefore, it greatly improves the practicality of the overall structure and realizes the function of improving structural stability and heat dissipation performance through the setting of the lateral winding, showing significant advantages in high power and high frequency scenarios.

[0022] 2. The transverse U-shaped common-mode inductor assembly proposed in this application solves the problem that existing common-mode inductors have an integrated core and related accessories, making it inconvenient for workers to replace the damaged part when it fails, thus affecting the use of the inductor. When the winding frame fails, it can be directly removed from the top of the core body, allowing the contact block at the bottom of the winding frame to separate from the contact groove at the top of the core body, thus removing the winding frame. When the winding frame needs to be installed, the contact block at the bottom of the winding frame is aligned with the contact groove at the top of the core body and inserted. The sealing ring on the outside of the contact block improves the connection stability between the winding frame and the core body. When the iron clamp body on one side of the winding frame needs to be removed, the iron clamp body is pulled to separate the groove on the iron clamp body from the protrusion on the outside of the winding frame. During installation, the groove inside the iron clamp body is aligned with the protrusion on the outside of the winding frame and inserted. The cooperation of friction block one and friction block two ensures that the iron clamp body is stably connected to one side of the winding frame, making it convenient for workers to replace the damaged part and reducing the cost of use.

[0030] Combination Figure 1 and Figure 2 A transverse U-shaped common mode inductor assembly includes an iron core body 1 and a winding frame 2 disposed on the top of the iron core body 1. The winding frame 2 is provided with two sets of coil windings. A bridging tape 3 is fixedly connected to one side of the winding frame 2. An iron clamp body 4 is also provided on one side of the winding frame 2. Two sets of protrusions 21 are fixedly connected to both the left and right sides of the winding frame 2.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the issues of current oversaturation, large size, complex manufacturing processes requiring shuttle winding or manual threading, and high overall cost associated with existing common-mode inductors due to the limitations of their magnetic ring common-mode material characteristics and lack of air gap, which necessitate complex manufacturing processes and the need for a compatible base, the following solution is disclosed. Please refer to the following for details. Figure 1 and Figure 2The iron clamp body 4 is located on one side of the bridge tape 3. By adjusting the magnetic circuit direction through the transverse U-shaped magnetic core on the winding frame 2, a more uniform magnetic flux density distribution can be achieved, reducing the risk of local magnetic saturation. Its horizontal symmetry design enhances the closure of the magnetic circuit, reduces the leakage magnetic ratio, and thus improves the magnetic coupling efficiency. The transverse arrangement of two sets of windings on the winding frame 2 significantly improves the core's anti-overturning ability. The wider winding window of the transverse U-shaped structure allows for the winding of larger diameter wires, enhancing current resistance and reducing copper loss. In contrast, the vertical U-shape is limited by height, which may lead to increased winding density, affecting heat dissipation and current carrying capacity. The transverse arrangement, due to its larger surface area and shorter heat dissipation path, can effectively reduce the core temperature rise. Its loss characteristics are negatively correlated with temperature. Combined with the optimized air gap design, the heat accumulation effect can be suppressed and the device life can be extended. The vertical U-shaped structure may cause heat concentration due to the vertical stacking structure, requiring additional heat dissipation measures. Therefore, it greatly improves the practicality of the overall structure and realizes the function of improving structural stability and heat dissipation performance through the setting of the lateral winding, showing significant advantages in high power and high frequency scenarios.

[0034] Example 2:

[0035] To address the issue that existing common-mode inductors, where the magnetic core and related components are integrated, making replacement of the damaged part inconvenient and affecting usability, the following solution is proposed. Please refer to the details below. Figures 2-4The bottom of the winding frame 2 is fixedly connected to a contact block 22, and the outer side of the contact block 22 is fixedly connected to a sealing ring 221. Multiple sets of sealing rings 221 are provided. A contact groove 23 is provided on the top of the iron core body 1. Multiple sets of contact grooves 23 and contact blocks 22 are provided, and the contact grooves 23 and contact blocks 22 are in sliding engagement. A groove 41 is provided on the inner side of the iron clamp body 4. Multiple sets of grooves 41 are provided, and the grooves 41 are in sliding engagement with protrusions 21. Friction blocks 212 are fixedly connected to both the upper and lower sides of the protrusions 21, and friction blocks 111 are fixedly connected to the grooves 41. Friction blocks 111 and friction blocks 212 are matched. When the winding frame 2 malfunctions, it can be directly removed from the top of the iron core body 1, causing the contact blocks 22 at the bottom of the winding frame 2 to separate from the contact grooves 23 at the top of the iron core body 1, thereby enabling… Remove the winding frame 2. When the winding frame 2 needs to be installed, align the contact block 22 at the bottom of the winding frame 2 with the contact groove 23 at the top of the core body 1 and insert it. The sealing ring 221 on the outer side of the contact block 22 improves the connection stability between the winding frame 2 and the core body 1. When the iron clamp body 4 on one side of the winding frame 2 needs to be removed, pull the iron clamp body 4 so that the groove 41 on the iron clamp body 4 separates from the protrusion 21 on the outer side of the winding frame 2. When performing the installation operation, align the groove 41 inside the iron clamp body 4 with the protrusion 21 on the outer side of the winding frame 2 and insert it. The cooperation between friction block 1 411 and friction block 2 412 makes the iron clamp body 4 stably connected to one side of the winding frame 2, which makes it convenient for workers to replace the damaged parts and reduces the cost of use.
