Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer frame. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).

[0003] The transformer bobbin is a key structural component of a transformer, and the term "bobbin" aptly describes its role within the transformer. Transformers are widely used in modern society, and their main components are indispensable; therefore, the bobbin plays an irreplaceable role. The main functions of the transformer bobbin are as follows: providing space for the copper wires to be wound; securing the magnetic core; providing a path for the wires during winding; supporting the copper wires with metal pins; connecting to the PCB board after soldering, providing conductivity during transformer operation; and determining the placement direction or pin sequence of the transformer based on the protrusions, concave points, or chamfers within the bobbin.

[0004] A transformer frame typically consists of coil posts and fixing plates at both ends of the coil posts, with spacers usually placed between the fixing plates. Transformer spacers play a crucial role in the transformer frame: in core design, spacers (such as ceramic spacers) create gaps in the core posts or contact surfaces to prevent magnetic saturation; they improve heat dissipation performance, making them applicable to high-power applications such as charging piles and photovoltaic energy storage, helping to control equipment temperature and ensure operational stability; and they optimize electrical isolation. Some spacer designs (such as segmented air gap technology) can improve magnetic flux distribution and reduce the risk of magnetic saturation by adjusting the air gap structure, while simultaneously achieving electrical isolation and improving equipment safety.

[0005] Currently, transformer frames typically use fixed separators, which are not easily adjustable. However, the magnetic flux distribution and temperature within the transformer vary under different voltage conditions. This necessitates the production of various specifications of transformer frames for different applications, incurring additional costs in mold making and production line setup. Therefore, an adjustable transformer frame is needed to adapt to diverse usage requirements. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a transformer frame that solves the problem that existing technologies have fixed separator structures, requiring the production of various specifications of transformer frames for transformers used in different environments, which leads to increased costs.

[0007] According to an embodiment of this utility model, a transformer frame includes a coil post and fixing plates respectively disposed at both ends of the coil post. The fixing plates are arranged perpendicular to the coil post. A mounting bracket is provided on the surface of the fixing plate away from the coil post. Two mounting brackets are arranged side by side on the fixing plate and are respectively installed on opposite sides of the fixing plate. The mounting brackets are perpendicularly installed on the fixing plate in the direction away from the coil post. The fixing plate is fixedly connected to the coil post through the center position. Several spacers are also provided between the fixing plates and sleeved on the outside of the coil post. The spacers are perpendicular to the coil post and can slide axially relative to the coil post. A limiter is also provided on the coil post. The limiter controls the movement of the spacers, so that the spacers can slide freely relative to the connecting rod or be stationary.

[0008] Furthermore, the vertical axial cross-sectional shape of the coil post is elliptical, and the middle of the spacer is provided with a through hole corresponding to the shape of the coil post. The coil post limits the through hole so that it can only move along the axis and cannot rotate.

[0009] Furthermore, both the partition and the fixing plate are square plate structures with rounded chamfers at the four corners.

[0010] Furthermore, a support rod is provided in the perforation of the partition, the support rod being parallel to the partition and dividing the perforation into two areas.

[0011] Furthermore, the coil column has a hollow structure, and its whole is a closed cylindrical shell with neither end extending outside the fixing plate.

[0012] Furthermore, the limiter includes an adjusting rod arranged parallel to the inside of the coil column. The adjusting rod is spaced apart from the central axis of the coil column, so that the adjusting rod will not contact the support rod when it passes through the perforation of each spacer. Several baffles are also provided on the outside of the support rod. The baffles are strip-shaped structures, and the spacing between adjacent baffles corresponds to the axial length of the support rod, so that the support rod can be precisely locked between two adjacent baffles. When the adjusting rod rotates, it adjusts the rotation angle of the baffles, so that the baffles are either clamped outside the support rod or do not contact the support rod.

[0013] Furthermore, one end of the adjusting rod extends through and beyond one of the fixed plates, and a knob is installed on the end.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the partition plate can slide axially relative to the coil post, while a limiter on the coil post controls the movement of the partition plate, allowing it to slide freely relative to the connecting rod or remain stationary. This allows for free adjustment of the partition plate's position and adjustment of its quantity by tightly fitting and merging the partition plates. This enables a single transformer frame to adapt to various voltage and current operating environments, allowing the production of multiple transformers from a single frame. This reduces the costs of mold making and production line setup in transformer frame production, and correspondingly improves production efficiency. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown in the figure, this utility model embodiment proposes a transformer frame, including a coil post 1 and fixing plates 2 respectively disposed at both ends of the coil post 1. The fixing plates 2 are arranged perpendicular to the coil post 1. A mounting bracket 21 is provided on the surface of the fixing plate 2 away from the coil post 1. Two mounting brackets 21 are arranged side by side on the fixing plate 2 and are respectively installed on opposite sides of the fixing plate 2. The mounting brackets 21 are perpendicularly installed on the fixing plate 2 in the direction away from the coil post 1. The fixing plate 2 is fixedly connected to the coil post 1 through its central position. The mounting brackets 21 allow for connection with other structures such as PCB boards. Furthermore, the mounting brackets 21 protrude away from the coil post 1, so they do not obstruct the winding operation.

[0020] Several spacers 3 are also provided between the fixing plates 2 and sleeved on the outside of the coil post 1. In this embodiment, two spacers 3 are provided. The spacers 3 are perpendicular to the coil post 1 and can slide axially relative to the coil post 1. A limiter is also provided on the coil post 1. The limiter controls the movement of the spacers 3, so that the spacers 3 can slide freely relative to the connecting rod or be stationary.

[0021] Preferably, the vertical axial cross-sectional shape of the coil post 1 is elliptical, and the spacer 3 has a through hole corresponding to the shape of the coil post 1 in the middle. The coil post 1 limits the movement of the through hole, allowing it to move only along the axis and preventing rotation. Furthermore, both the spacer 3 and the fixing plate 2 are square plate structures with rounded chamfers at the four corners. This prevents workers from being scratched by sharp edges during processing or use.

[0022] In a further embodiment, a support rod 31 is also provided in the perforation of the partition 3. The support rod 31 is parallel to the partition 3 and divides the perforation into two areas. Correspondingly, the coil post 1 is a hollow structure, which is a closed cylindrical shell with both ends not extending outside the fixing plate 2.

[0023] like Figure 2 As shown, the limiting device includes an adjusting rod 4 parallel to the inside of the coil post 1, which is rotatably connected to the end faces of the support rod 31. The adjusting rod 4 has a certain gap from the central axis of the coil post 1, ensuring that the adjusting rod 4 does not contact the support rod 31 when passing through the holes of each spacer 3. Several baffles 5 are also provided on the outside of the support rod 31. Each baffle 5 is a strip-shaped structure, and the spacing between adjacent baffles 5 corresponds to the axial length of the support rod 31, allowing the support rod 31 to be precisely positioned between two adjacent baffles 5. The adjusting rod 4 rotates to adjust the rotation angle of the baffles 5, so that the baffles 5 are either clamped outside the support rod 31 or do not contact the support rod 31. Therefore, when the position of the spacer 3 needs to be adjusted, rotating the adjusting rod 4 until the baffles 5 do not contact the support rod 31 allows the spacer 3 to slide freely along the coil post 1. After sliding to the designated position, rotating the adjusting rod 4 again until the baffles 5 precisely clamp the support rod 31 in the middle completes the fixation of the spacer 3.

[0024] In a preferred embodiment, one end of the adjusting rod 4 extends through one of the fixed plates 2 and a knob 41 is installed on the end. The rotation of the adjusting rod 4 can be controlled externally by the knob 41. At the same time, the end face of the adjusting rod 4 and the coil post 1 adopts a non-slip connection with friction, so that it will not rotate on its own when no external force is applied.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
