[0034] Reference Figure 1 as well as Figure 2 According to the transformer skeleton of the first embodiment of the utility model, the transformer skeleton includes a central magnetic column, a first retaining wall and a second retaining wall. On the central magnetic column, a through hole is arranged along the length direction of the central magnetic column, and a plurality of heat dissipation holes are arranged on the side of the central magnetic column. The outer side of the central magnetic column is used for winding the winding, and the through hole is used for accommodating the iron core; the first retaining wall is arranged at one end of the central magnetic column, and the first retaining wall protrudes in a direction perpendicular to the side of the central magnetic column; the second retaining wall is arranged at the other end of the central magnetic column, and the second retaining wall protrudes in a direction perpendicular to the side of the central magnetic column. A baffle is arranged at the outer end of the second retaining wall, and the baffle protrudes in a direction perpendicular to the side of the second retaining wall.

[0035] Specifically, the transformer skeleton mainly includes a central magnetic column, a first retaining wall and a second retaining wall. The central magnetic column is the main part of the transformer skeleton, and its shape is a long column, and its cross-sectional shape can be circular, rectangular, etc. A through hole is arranged along the length direction of the central magnetic column, and this through hole is mainly used to accommodate the iron core. The iron core is an important part of the transformer, and it is inserted into the central magnetic column through the through hole to enhance the magnetic properties of the transformer. On the side of the central magnetic column, a number of heat dissipation holes are arranged. These heat dissipation holes are evenly distributed on the side of the central magnetic column, which can effectively dissipate the heat generated when the transformer is working, prevent the transformer from overheating, and thus increase the service life of the transformer. The outer side of the central magnetic column is used for winding. The winding can be evenly wound around the outer side of the central magnetic column, and the voltage conversion is realized through the principle of electromagnetic induction.

[0036] The first retaining wall is arranged at one end of the central magnetic column, and it protrudes in a direction perpendicular to the side of the central magnetic column. The main function of the first retaining wall is to prevent the winding from sliding off at the end of the central magnetic column. At the same time, it can also play a certain supporting and fixing role, thereby enhancing the stability of the winding. The second retaining wall is arranged at the other end of the central magnetic column, corresponding to the first retaining wall. The second retaining wall also protrudes in a direction perpendicular to the side of the central magnetic column, and its function is the same as that of the first retaining wall, which is used to prevent the winding from sliding off and to support and fix the winding. A baffle is also arranged at the outer end of the second retaining wall. This baffle protrudes in a direction perpendicular to the side of the second retaining wall, and it can further prevent the winding from sliding off from the outer side of the second retaining wall, thereby improving the safety of the transformer.

[0037] It should be noted that the second retaining wall provided on the transformer frame can increase the distance from the outgoing line side of the winding to the terminal, so that the winding and the terminal maintain a safe distance; in addition, the addition of the second retaining wall can also reduce the acetate tape wrapped around the transformer frame, saving material costs and labor costs.

[0038] Therefore, the transformer skeleton according to the embodiment of the utility model has at least the following beneficial effects: heat dissipation holes are arranged on the side of the central magnetic column, which can be used to dissipate heat during the use of the transformer; in addition, the central magnetic column is arranged between the first retaining wall and the second retaining wall, which can fix the distance between the winding and the iron core while increasing the space between the two, thereby being more conducive to the heat dissipation of the transformer and thus improving the reliability of the transformer.

[0039] Reference Figure 1 , Figure 2 as well as Figure 3 In some embodiments of the utility model, two third retaining walls are arranged at the outer end of the first retaining wall, the two third retaining walls are arranged opposite to each other and symmetrically, the inner side surface of the third retaining wall is flush with the inner surface of the through hole, and two limit blocks are also arranged on the inner side surface of the third retaining wall, the two limit blocks of the two third retaining walls are arranged opposite to each other, and the limit blocks are used to abut the iron core of the transformer.

[0040] Furthermore, two third retaining walls are provided at the outer end of the first retaining wall. The two third retaining walls are arranged opposite to each other and are symmetrically distributed. The inner side surface of the third retaining wall is kept flush with the inner surface of the through hole. Such a design makes the overall structure more compact and is also conducive to the insertion and fixation of the iron core. In order to further ensure the stability and position accuracy of the iron core, two limit blocks are provided on the inner side surface of each third retaining wall. These limit blocks are arranged opposite to each other in pairs. When the iron core is inserted into the through hole, the limit blocks can effectively abut the iron core to prevent it from moving or shaking. The design of the limit blocks not only improves the fixing effect of the iron core, but also provides space for heat dissipation of the transformer, thereby providing additional protection for the safe operation of the transformer. They ensure that the iron core always remains in the correct position during the operation of the transformer, thereby avoiding performance degradation or safety hazards that may be caused by the displacement of the iron core.

[0041] In general, by adding the third retaining wall and the limit block, the transformer skeleton is further optimized in structure, which not only improves the stability of the core and the overall performance of the transformer, but also enhances the safety and reliability of the transformer.

[0042] Similarly, refer to Figure 1 , Figure 2 as well as Figure 3 In some embodiments of the utility model, two fourth retaining walls are arranged at the outer end of the baffle, the two fourth retaining walls are arranged opposite to each other and symmetrically, the inner side surface of the fourth retaining wall is flush with the inner surface of the through hole, and two limit blocks are also arranged on the inner side surface of the fourth retaining wall, the two limit blocks of the two fourth retaining walls are arranged opposite to each other, and the limit blocks are used to abut the iron core of the transformer.

[0043] On the basis of the transformer skeleton described in the above embodiment, two fourth retaining walls can be set at the outer end of the baffle. The two fourth retaining walls are arranged relative to each other and present a symmetrical layout. At the same time, they can also be symmetrically arranged with the two third retaining walls, thereby further improving the structural stability and supporting capacity of the transformer skeleton. It is worth noting that the inner side of the fourth retaining wall is flush with the inner surface of the through hole. Such a design not only optimizes the overall appearance and structure, but also ensures that the iron core can be smoothly and accurately inserted into the through hole of the central magnetic column.

[0044] It should be emphasized that, by the same token, two limit blocks are designed on the inner side of each fourth retaining wall. These limit blocks are opposite to each other, forming a stable support structure. When the iron core is inserted, these limit blocks can effectively abut the iron core to ensure the stability and accuracy of its position. By adding the fourth retaining wall and limit blocks, the stability and functionality of the transformer skeleton are enhanced, which not only helps to protect the iron core from damage, but also provides space for heat dissipation for the transformer, ensuring that the transformer always maintains high performance and stability during long-term operation.

[0045] Reference Figure 1 , Figure 2 as well as Figure 3 In some embodiments of the utility model, a plurality of wire outlet grooves are provided on the first side surface and the second side surface of the baffle, and the first side surface of the baffle and the second side surface of the baffle are arranged opposite to each other, and the wire outlet grooves are used to accommodate the wire outlet ends of the windings.

[0046] Specifically, a plurality of outlet grooves are provided on the first side and the second side of the baffle. These outlet grooves are designed to accommodate the outlet ends of the windings, thereby providing a neater and more orderly cable management. The first side and the second side of the baffle are opposite, and the outlet grooves are provided on these two sides. Such a layout not only ensures that the outlet ends can be placed in the corresponding outlet grooves in an orderly manner, but also effectively avoids the crossing and confusion between the cables, thereby improving the overall safety and reliability. When the winding is wound on the central magnetic column, its outlet end can be conveniently led out through the outlet groove on the baffle, which greatly simplifies the connection and fixing of the cables. At the same time, the design of the outlet groove also effectively protects the cables and avoids possible wear or damage during the operation of the transformer.

[0047] Further, refer to Figure 1 , Figure 2 as well as Figure 3 In some embodiments of the utility model, the wire outlet groove on the first side of the baffle includes a first wire groove and a second wire groove, the bottom of the first wire groove abuts against the outer side of the fourth baffle wall, and the bottom of the second wire groove abuts against the outer side of the second baffle wall.

[0048] Specifically, the outlet groove on the first side of the baffle includes a first groove and a second groove, which have different positions and functions. In the first groove, the bottom of the groove of the first groove abuts against the outer side of the fourth retaining wall. Such a design ensures that the cable can be firmly placed in the first groove after being led out from the winding, and the fourth retaining wall provides a stable support for the first groove, which helps to prevent the cable from moving or loosening during the operation of the transformer, thereby improving the stability and reliability of the cable connection. In the second groove, the bottom of the groove of the second groove abuts against the outer side of the second retaining wall. Similar to the first groove, the second groove also utilizes the existing structure of the transformer skeleton (i.e., the second retaining wall) to provide stable support. By placing the cable in the second groove, the neatness and order of the cables can be further ensured, and it also helps to protect the cables from damage.

[0049] It is understandable that the bottom of the first wire groove is deeper than the bottom of the second wire groove in the depth direction, so the first wire groove has higher recognition and better accommodation performance, so the transformer frame can be quickly installed and the output terminal of the winding with a larger wire diameter can be accommodated through the position of the first wire groove.

[0050] Reference Figure 1 In some embodiments of the utility model, the cross-section of the central magnetic column is set in a rectangular shape, and the heat dissipation holes are located on two opposite sides of the central magnetic column. The cross-section of the central magnetic column is designed to be rectangular, which not only enhances the structural strength of the skeleton, but also enables the winding to be more evenly wound on the central magnetic column, thereby improving the efficiency and performance of the transformer. In addition, the heat dissipation holes are arranged on two opposite sides of the central magnetic column, ensuring that the heat dissipation holes can effectively promote the dissipation of heat and prevent the transformer from overheating during operation. Specifically, when the transformer is working, the heat generated will be quickly dissipated to the external environment through the heat dissipation holes, thereby keeping the temperature inside the transformer within a safe and stable range. Setting them on two opposite sides of the central magnetic column can ensure uniform heat dissipation and avoid local overheating. This design not only improves the heat dissipation efficiency of the transformer, but also extends the service life of the transformer.

[0051] Reference Figures 2 to 4 According to the transformer of the second aspect of the utility model, the transformer includes the transformer skeleton of any one of the embodiments of the first aspect. The transformer also includes a winding, an iron core and a bottom plate. The winding is wound on the central magnetic column; the iron core is sleeved on the outside of the transformer skeleton and inserted into the through hole; the bottom plate is provided with a positioning groove, the positioning groove is used to accommodate one side of the iron core, and the bottom plate is provided with a wire outlet hole, and the wire outlet end of the winding passes through the wire outlet hole.

[0052] Specifically, the utility model also provides a transformer, which not only includes the transformer skeleton of any one of the embodiments of the first aspect above, but is further equipped with windings, iron cores and bottom plates, which together constitute a complete and efficient transformer system. First, the windings are tightly and evenly wound on the central magnetic column. This winding method ensures that the transformer can efficiently perform electromagnetic conversion when working, thereby improving the overall performance of the transformer. Secondly, the iron core is sleeved on the outside of the transformer skeleton and tightly inserted into the through hole of the central magnetic column. As an important component of the transformer, the iron core is used to enhance the magnetic field and improve the efficiency of electromagnetic conversion. Through close integration with the transformer skeleton, the iron core can effectively transmit magnetic lines of force, thereby achieving efficient energy conversion. Finally, the bottom plate plays a key supporting and fixing role in the transformer. A positioning groove is provided on the bottom plate, which accurately accommodates one side of the iron core, ensuring the stable position of the iron core in the transformer. At the same time, a wire outlet hole is also provided on the bottom plate. The design of the wire outlet hole is ingenious to allow the wire outlet of the winding to pass through the hole without winding the wire with the PIN pin, which is convenient for connecting the cable and the product to be connected, and ensures the neatness and orderliness of the overall structure. In addition, the transformer includes the transformer skeleton of the embodiment of the first aspect, and the transformer has good heat dissipation performance, so that the transformer has a longer service life.

[0053] Reference Figure 3 In some embodiments of the utility model, the bottom plate is provided with an avoidance portion, which is used to avoid components at the installation position to facilitate the installation of the transformer.

[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
