Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] In order to solve the technical problem of poor anti-vibration effect of the reactor in the prior art, the present application provides an anti-vibration reactor.

[0026] See also Figure 1 and Figure 5In a possible implementation manner, the vibration-proof reactor of the utility model comprises: an internal reinforcement fixing connecting plate 1, the two ends of the internal reinforcement fixing connecting plate 1 are respectively connected to the upper yoke core 2 and the lower yoke core 3 of the reactor, the middle column core is installed between the upper yoke core 2 and the lower yoke core 3, every two or more internal reinforcement fixing connecting plates 1 clamp the middle column core, the winding is wound outside the middle column core, and the winding is encapsulated with an insulating structure 6 outside the encapsulation; wherein, three middle column cores are provided; six internal reinforcement fixing connecting plates 1 are provided, A long strip of metal or non-metal plate; every two internal reinforcing fixed connecting plates 1 are correspondingly arranged, and the two internal reinforcing fixed connecting plates 1 clamp a middle column iron core; it also includes: a lower yoke clamping sheet metal 31 and a lower base plate 7, the lower yoke clamping sheet metal 31 is fastened and installed on the outer periphery of the lower yoke iron core 3, the internal reinforcing fixed connecting plates 1 are connected to the lower yoke clamping sheet metal 31 by bolts, the lower yoke clamping sheet metal 31 is fixedly installed at both ends of the lower base plate 7, the lower base plate 7 and the lower yoke clamping sheet metal 31 have a protruding bend, and the two are welded at the bend.

[0027] In the above scheme, see Figure 1a An internal strengthening and fixing connecting plate 1 is provided with an upper opening 11 at the top, and the upper opening 11 is connected to the upper yoke iron core by bolts. A lower opening 12 is provided at the bottom, and the lower opening 12 is connected to the lower yoke iron core by bolts.

[0028] In the above scheme, the vibration-resistant reactor of the present invention effectively enhances the overall stability and vibration resistance of the reactor through the specially designed internal reinforcement fixing connecting plate 1 and the structure of the lower yoke clamping sheet metal 31 and the lower base plate 7. The use of the internal reinforcement fixing connecting plate 1 not only enhances the fixation of the middle column core, but also improves the structural stability of the entire reactor through its connection with the upper and lower yoke cores 2 and 3. The design of clamping a middle column core with every two internal reinforcement fixing connecting plates 1 ensures the stability of the middle column core during the operation of the reactor and reduces the generation of vibration. In addition, the material of the internal reinforcement fixing connecting plate 1 can be metal or non-metal, providing more options to adapt to different application environments. The design of the lower yoke clamping sheet metal 31 and the lower base plate 7 not only provides a stable installation foundation for the reactor, but also further increases the stability and durability of the structure through the protruding bends 71 ​​and welds. This design enables the reactor to maintain good performance in various vibration environments and extend its service life.

[0029] In the above scheme, the bend II 71 of the lower base plate 7 is welded to the bend I 32 of the lower yoke clamping sheet metal 31 to strengthen the connection between the lower base plate 7 and the lower yoke core 3 and enhance the stability of the reactor.

[0030] In the above solution, welding is further performed at the contact position a between the lower base plate 7 and the lower yoke clamping sheet metal 31 to further enhance the stability of the reactor.

[0031] Figure 2 In the figure, position a is the welding position of the lower bottom plate 7 and the lower yoke clamping sheet metal 31. The welding of the base of the ordinary reactor and the clamping sheet metal is generally only welded at the plane contact position. The bottom plate 7 of the present application adds a vertical sheet metal structure, that is, bend II 71, and the lower yoke clamping sheet metal 31 adds bend I 32. Both increase the vertical welding surface and increase the ability to withstand lateral / vertical vibrations.

[0032] See also Figure 3 In a possible implementation manner, a vertical fixing hole 9 is provided at the bending part of the lower base plate 7 , namely, the bending II 71 , and the reactor is fixedly installed through the vertical fixing hole 9 .

[0033] Planar fixing holes 8 are provided on the bottom plate 7, and the reactor is installed in two dimensions through the planar fixing holes 8 and the vertical fixing holes 9, thereby increasing stability.

[0034] In the above scheme, the flexibility and convenience of the reactor installation are further increased by providing a vertical fixing hole 9 at the bend of the lower base plate 7. The provision of the vertical fixing hole 9 allows the reactor to be easily fixed at a predetermined position by bolts or other fixing components, thereby improving installation efficiency and stability. This design is particularly important for applications that require the reactor to be installed at a specific location or in a limited space, ensuring the stability of the reactor during operation and reducing vibration problems that may be caused by unstable installation.

[0035] In a possible implementation, it further includes: an upper yoke clamping sheet metal 21, which is fastened and installed on the outer periphery of the upper yoke core 2, and the internal reinforcing fixed connecting plate 1 is connected to the upper yoke clamping sheet metal 21 by bolts.

[0036] In the above scheme, the design of the upper yoke clamping sheet metal 21 is added, which echoes the lower yoke clamping sheet metal 31, forming a double upper and lower fixed structure, further enhancing the overall stability and vibration resistance of the reactor. The setting of the upper yoke clamping sheet metal 21 not only fixes the upper yoke core 2, but also strengthens the connection with the internal fixed connecting plate 1 through bolts, forming a tighter and more stable structure. This design effectively reduces the displacement and damage risk of the reactor in a high vibration environment, ensuring the long-term stable operation of the reactor.

[0037] See also Figure 4 In a possible implementation manner, bent fixing ears 22 are provided at both ends of the upper yoke clamping sheet metal 21, and mounting holes are provided on the fixing ears 22, and the reactor is installed through the mounting holes.

[0038] After the upper yoke core clamps the sheet metal and extends left and right, there are fixing ears 22. This fixing ear can be straight, bent, bent and welded, or in other shapes. It can be fixed, such as having a thread hole, a welded nut, and being fixed to the sheet metal in the cabinet by bolts or other structures. It can also be a round hole, an elliptical hole, a square hole, etc., which is penetrated by bolts or other fixing parts and fixed to other sheet metals in the cabinet.

[0039] The fixing ear 22 effectively stabilizes the upper area of ​​the reactor, moves the center of vibration upward, effectively reduces the vibration pressure of the bottom sheet metal, and improves the stability of the upper part, thereby increasing the anti-seismic ability of the product in the front-to-back direction and the left-to-right direction.

[0040] In the above scheme, the design of the bent fixing ears 22 and the mounting holes at both ends of the upper yoke clamping sheet metal 21 provides more flexibility and stability for the installation of the reactor. The setting of the fixing ears 22 not only simplifies the installation process, but also allows the reactor to be more firmly installed on different support structures through the design of the mounting holes. This design effectively copes with the challenges that may be encountered in complex installation environments and ensures that the reactor can maintain stability and reliability even in high vibration or harsh environments.

[0041] In a possible implementation manner, the openings through which the bolts pass in the internal reinforcing fixing connecting plate 1 are square holes, round holes or elliptical holes.

[0042] The internal reinforcement fixing connecting plate 1 is a metal or non-metallic connecting plate with holes in the upper and lower parts, which can be square holes, round holes or elliptical holes. When assembling, it can clamp the iron core and connect the upper yoke iron core, the middle column iron core and the lower yoke iron core of the reactor iron core as a whole with the fastening bolts. The common structure reactor only has fastening bolts to connect the upper and lower yokes, and its resistance to left and right and front and back vibration is weak. This structure effectively enhances the vibration in the front and back and left and right directions, and with the fastening bolts to connect the upper and lower parts, the vibration in the upper and lower directions is further enhanced.

[0043] In the above scheme, the bolt opening design of the internal reinforcement fixing connecting plate 1 provides a variety of options, including square holes, round holes and elliptical holes, which increases the flexibility and adaptability of component connection. Openings of different shapes can be selected according to actual needs and bolt specifications to ensure the tightness and stability of the connection. This design takes into account the different installation and fixing requirements that may be encountered in actual applications, and improves the applicability and reliability of the reactor.

[0044] In a possible implementation manner, the fixing ear 22 is provided with a thread hole, a welding nut, or a round hole, an elliptical hole, or a square hole, through which a bolt or other fixing component is inserted.

[0045] In the above solution, the design of the fixing ear 22 further improves the flexibility and stability of the reactor installation. By setting a thread hole, a welding nut or a design that adapts to openings of different shapes, the fixing ear 22 can adapt to various bolts or fixing components, ensuring the stable installation of the reactor. This design makes the installation process of the reactor simpler and faster, while ensuring stability and reliability under various operating conditions, thereby improving the service life and performance of the reactor.

[0046] The winding of the winding starts from the coil starting row 52 and ends at the coil ending row 51; the winding is encapsulated with an insulating structure 6.

[0047] In a possible implementation manner, the installation directions of the mounting hole of the fixing ear 22 , the vertical fixing hole 9 of the bending portion II 71 , and the planar fixing hole 8 of the lower base plate 7 are respectively oriented in different directions.

[0048] In the above scheme, the installation directions of the fixing ear 22, the vertical fixing hole 9 at the bend II 71 and the planar fixing hole 8 of the lower base plate 7 are respectively facing different directions, so that the inductor provides stable support in various directions of up and down, left and right, front and back, improves the vibration resistance of the inductor, and ensures the stable operation of the inductor.

[0049] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
