[0002] Traditional transformers usually use bolts to compress the iron core of the transformer, and the bolts are in rigid contact with the iron core of the transformer. This mode is easy to damage the insulation layer of the silicon steel sheet. In addition, during the operation of the traditional transformer, the iron core is prone to looseness due to thermal expansion and contraction of the iron core or battery vibration, which easily leads to distortion of the magnetic flux distribution, thereby increasing the loss. SUMMARY

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-8 The present invention provides a technical solution: a transformer assembly, including a transformer body, the transformer body including a shell, (laminated) iron core, coil winding, protection device, heat dissipation device and leads and terminals and other components (not shown in the figure), all of which are prior art and will not be described in detail here.

[0031] The transformer assembly also includes a clamping mechanism, which clamps the core of the transformer body through multiple clamping mechanisms. The clamping mechanism includes two symmetrically arranged bases 1, both of which are used to be installed and fixed on the outer shell of the transformer body. A support seat 2 is fixedly arranged on the base 1. An elastic support member 3 is provided on each support seat 2. The two elastic support members 3 are symmetrically arranged, and the core is clamped between the two elastic support members 3.

[0032] The elastic support 3 is composed of a cylindrical part 31, a conical part 32 and a V-shaped end 33. The cylindrical part 31, the conical part 32 and the V-shaped end 33 are integrally formed. The entire elastic support 3 is made of a material with high strength and elasticity, such as spring steel.

[0033] The conical section 32 is connected to the cylindrical section 31. The end of the conical section 32 away from the cylindrical section 31 is connected to a plurality of V-shaped ends 33. The plurality of V-shaped ends 33 are evenly distributed around the axis of the cylindrical section 31. Furthermore, there is a gap between two adjacent V-shaped ends 33.

[0034] The V-shaped end 33 consists of an inclined portion 332 and a horizontal portion 331. The inclined portion 332 is used to connect to the tapered portion 32, while the horizontal portion 331 is used to abut against the end face of the iron core.

[0035] Meanwhile, a U-shaped protrusion 5 is fixedly provided on each horizontal part 331. The U-shaped protrusion 5 is made of metal, such as steel, and is fixed to the horizontal part 331 by welding. A spherical member 6 is placed inside each U-shaped protrusion 5. Both the U-shaped protrusion 5 and the spherical member 6 are located between the horizontal part 331 and the inclined part 332, and the spherical member 6 is limited between the U-shaped protrusion 5 and the inclined part 332.

[0036] When the clamping mechanism clamps the iron core, the axes of the cylindrical part 31 and the conical part 32 are set horizontally. Since the spherical part 6 is placed inside the U-shaped protrusion 5, under the action of weight, part of the spherical part 6 contacts the inner side of the inclined part 332, and part of the spherical part 6 contacts the inner wall of the U-shaped protrusion 5.

[0037] Specifically, the spherical component 6 can be made of steel ball 61.

[0038] The iron core is held by multiple clamping mechanisms, such as... Figure 1 As shown, the clamping mechanism clamps the edge of the iron core; the iron core is clamped by the elastic support 3, specifically, by multiple horizontal parts 331 pressing against both ends of the iron core, and at this time the V-shaped end 33 deforms to a certain extent; since the elastic support 3 is elastic, it is easy to adapt to the thermal expansion and contraction of the iron core, thus improving the service life of the iron core; in addition, it can also reduce the vibration of the iron core during operation, which helps to reduce or avoid the iron core from loosening.

[0039] Because it is also equipped with U-shaped protrusions 5 and steel balls 61, when the thermal expansion of the iron core causes some V-shaped ends 33 to deform significantly, the steel balls 61 corresponding to the V-shaped ends 33 can easily squeeze the inclined parts 332, thereby enhancing the overall deformation of the elastic support 3, thus suppressing the excessive expansion of the iron core and reducing or avoiding situations such as magnetic circuit asymmetry; at the same time, when the overall deformation of the elastic support 3 increases, it is also easier to resist greater vibration and impact, enhancing the buffering and shock absorption effect on the iron core.

[0040] Example 2

[0041] See again Figures 1-4 This embodiment, based on Embodiment 1, also includes a connecting component 4, which is positioned between the two support bases 2. Figure 2 As shown, two connection components 4 are set up.

[0042] The connecting component 4 includes a limiting rod 41, which is used to cooperate with the support base 2. Each support base 2 is provided with a slot 21 that is adapted to the limiting rod 41, and the number of slots 21 is equal to the number of limiting rods 41. One end of each of the two limiting rods 41 is fixed to one of the support bases 2 by two nuts 42, and the two limiting rods 41 are respectively engaged in the two slots 21 on the support base 2. At the same time, the two limiting rods 41 are also respectively engaged in the two slots 21 on the other support base 2.

[0043] One end of the limiting rod 41 is provided with a threaded structure, and the nut 42 is adapted to this threaded structure; for example Figure 3 As shown, by threading two nuts 42 onto the limiting rod 41, the two nuts 42 abut against the two sides of one of the support seats 2, specifically against the opposite outer walls of the two sides of that part, that is, a part of the support seat 2 is clamped by the two nuts 42, thereby fixing the limiting rod 41.

[0044] In addition, each limiting rod 41 is respectively engaged between two adjacent V-shaped ends 33 of each elastic support 3; the slot 21 is composed of a semi-circular slot and a square slot, and the limiting rod 41 can be removed from the slot 21 by removing the nut 42.

[0045] In this embodiment, the limiting rod 41 is engaged in the slot 21. When the iron core is clamped by the elastic support 3, the limiting rod 41 is kept as far away from the iron core as possible. Although the support 2 can rotate, the friction between the elastic support 3 and the iron core requires a large force to rotate the support 2. Therefore, when the elastic support 3 deforms significantly due to the thermal expansion or vibration of the iron core, and the V-shaped end 33 in contact with the limiting rod 41 deforms significantly, the limiting rod 41 moves, thus realizing the linkage between the two elastic support 3. This is beneficial to enhance the overall effect of suppressing the thermal expansion deformation of the iron core and the shock absorption effect.

[0046] Furthermore, the locking groove 21 cooperates with the limiting rod 41, and a nut 42 is provided, which can fix the limiting rod 41 to any support 2.

[0047] Example 3

[0048] See again Figure 3 and Figure 5 Based on Embodiment 2, in order to facilitate the cooperation between the elastic support 3 and the support base 2, a matching groove 22 adapted to the cylindrical part 31 is provided on the support base 2, and the cylindrical part 31 can be fitted into the matching groove 22.

[0049] In addition, the base 1 is provided with multiple mounting holes 11, which facilitates the mounting and fixing of the base 1 onto the transformer casing.
