[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figs. 1-3 In the embodiments of the present application, a network transformer comprises:

[0027] A housing 1 has an inner groove 2, and a plurality of magnetic rings 3 are arranged in the inner groove 2 at intervals. A slot 4 that communicates with the inner groove 2 is arranged on the side wall of the housing 1, and the slot 4 extends radially along the housing 1.

[0028] An isolation sheet 5 has a sheet structure, and its size matches the slot 4 of the housing 1, and the isolation sheet 5 can be installed between two adjacent magnetic rings 3 through the slot 4.

[0029] Silicone grease 6 is used to fill the gaps between the housing 1, the magnetic rings 3, and the isolation sheet 5, so that the housing 1, the magnetic rings 3, and the isolation sheet 5 are connected to form an integrated structure.

[0030] In the technical solutions of the present application, the magnetic rings 3 are core components for realizing electromagnetic conversion of the network transformer, and the layout of the magnetic rings 3 is crucial to the performance of the transformer. The plurality of magnetic rings 3 are arranged in the inner groove 2 at intervals, and different magnetic rings 3 can process different frequency band signals. For example, when processing high-frequency signals, the number of turns, material, and other parameters of a specific magnetic ring 3 are optimized, so that electromagnetic conversion can be more efficiently completed. Low-frequency signals are processed by magnetic rings 3 with other parameters. The isolation sheet 5 is installed between the adjacent magnetic rings 3. Based on the principle of electromagnetic shielding, the isolation sheet 5 has a special material structure, such as a multi-layer composite structure or contains specific shielding particles, which can effectively block the electromagnetic interference propagation path between the magnetic rings 3. When the electromagnetic interference signal generated by one magnetic ring 3 propagates to the isolation sheet 5, the material of the isolation sheet 5 scatters, reflects, or absorbs the interference signal, so that the intensity of the interference signal is greatly attenuated, thereby reducing the influence on the adjacent magnetic ring 3, allowing each magnetic ring 3 to generate a relatively independent and stable magnetic field, and effectively improving the electromagnetic compatibility of the transformer.

[0031] The slot 4 of the outer shell 1 is precisely designed according to the size and shape of the isolation plate 5, providing accurate positioning for the isolation plate 5. During installation, the isolation plate 5 can be easily and accurately embedded into the slot 4, ensuring the accuracy of its installation position and thus fully exerting its isolation function. The silicone grease 6 fills the tiny gaps between the outer shell 1, the magnetic ring 3, and the isolation plate 5. Its adhesiveness allows the components to fit tightly in the initial stage. As the silicone grease 6 cures, it forms a connection structure with a certain mechanical strength. This cured connection structure significantly enhances the bonding force between components through intermolecular forces and chemical bonding forces generated by curing. During equipment operation, even if it encounters vibration or temperature changes, it can effectively prevent the components from loosening and maintain the stability of the network transformer structure.

[0032] In summary, this network transformer effectively reduces electromagnetic interference between the three magnetic rings, making the magnetic field more stable during transformer operation and improving the stability and accuracy of signal transmission to a certain extent. In high-speed, high-capacity communication, it helps ensure accurate data transmission, reducing signal distortion and bit error rate. The integrated connection structure enhances overall stability and reduces the risk of component loosening due to vibration, temperature changes, and other factors. It reduces the probability of equipment failure during operation, reduces maintenance costs and downtime, and improves the reliability and lifespan of network equipment, making it particularly suitable for environments with high equipment stability requirements, such as industrial control and data centers.

[0033] In this embodiment of the present invention, a winding wire 7 is wound on the magnetic ring 3, and a wire groove 8 is provided at the end of the isolation plate 5. The wire groove 8 is used to embed and fix the winding wire 7.

[0034] According to the law of electromagnetic induction, a winding wire 7 is wound on the magnetic ring 3. When an alternating current passes through the winding wire 7, an alternating magnetic field is generated in the magnetic ring 3. Conversely, the alternating magnetic field in the magnetic ring 3 will also induce an electromotive force in the winding wire 7, thereby realizing the mutual conversion of electrical energy and magnetic energy. This is the basis for the network transformer to realize signal transmission and processing. The end of the isolation plate 5 is provided with a wire groove 8, the size and shape of which are adapted to the winding wire 7. The wire groove 8 physically constrains the winding wire 7, so that the winding wire 7 maintains a fixed position during the operation of the transformer, avoiding the impact of shaking, displacement, etc. on the stability of electromagnetic induction, and ensuring the efficient conversion of electrical energy and magnetic energy.

[0035] In this embodiment of the present invention, the number of slots 4 is the same as the number of isolation plates 5, and their distribution on the side wall of the outer shell 1 corresponds to the gap position of the magnetic ring 3.

[0036] The number of the slot positions 4 is consistent with the number of the isolation sheets 5, so as to realize one-to-one accurate installation and ensure that each position needing isolation has a corresponding isolation sheet 5; and the distribution of the slot positions 4 on the side wall of the shell 1 and the gap position of the magnetic ring 3 correspond, which is based on the consideration of the layout of the magnetic ring 3 on the isolation demand, because the gap of the magnetic ring 3 is an area where electromagnetic interference is easy to spread between the magnetic rings 3, the installation of the isolation sheet 5 in this position through the corresponding slot position 4 can maximally block the propagation path of the electromagnetic interference, so that the isolation sheet 5 can accurately play the role of isolating the electromagnetic interference.

[0037] In the embodiment of the utility model, the isolation sheet 5 is made of ceramic matrix composite material.

[0038] The internal atomic structure of the ceramic matrix composite material is orderly, and the electron cloud distribution is stable, which can effectively hinder the penetration of electromagnetic signals. When external electromagnetic interference meets the isolation sheet 5, the internal ceramic crystal structure of the isolation sheet 5 can cause scattering and reflection of the electromagnetic interference signal, thereby attenuating the interference signal and reducing the influence of the interference signal on the magnetic ring 3 and the winding inside the transformer; the material also has high resistivity, and the movement of electrons in it is difficult, which can effectively prevent current leakage. Inside the transformer, the isolation sheet 5 needs to isolate components of different potentials, and the insulation characteristics of the ceramic matrix composite material can avoid electrical faults caused by leakage, ensure the electrical independence between components, and maintain the normal operation of the transformer.

[0039] In the embodiment of the utility model, the wire passing groove 8 is in the shape of a dovetail groove.

[0040] The dovetail groove is in the shape of a trapezoid, and the two side walls are inclined surfaces. When the winding wire 7 is embedded in the dovetail groove, the winding wire 7 is subjected to pressure from the two side inclined surfaces of the dovetail groove. As the embedding depth of the winding wire 7 increases, the friction force generated by the pressure will prevent the winding wire 7 from being pulled out in the opposite direction along the embedding direction, thereby realizing mechanical self-locking effect and ensuring that the winding wire 7 is stably fixed in the wire passing groove 8.

[0041] In the embodiment of the utility model, the shell 1 is integrally formed with the pin 9 through an injection molding process, so as to realize electrical connection with an external circuit through the pin 9.

[0042] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
