Description

Technical Field

[0001] This application belongs to the field of transformer technology, specifically relating to a transformer frame and a transformer. Background Technology

[0002] Transformers, as key magnetic components in switching power supplies, are widely used in various electronic devices. A transformer generally includes a magnetic core, a transformer frame, a primary coil, and a secondary coil. The secondary coil is connected to secondary pins, which are used to connect to circuit boards to achieve energy transfer and conversion.

[0003] However, the secondary coil and secondary pins are generally made of multi-strand enameled copper wire. Copper wire is soft, which makes the secondary pins easy to deform under external force. Deformation of the secondary pins will not only affect the precise connection between them and the circuit board, but also have a negative impact on the performance of the transformer. Utility Model Content

The first limiting structure and the second limiting structure are distributed on opposite sides of the secondary winding groove along the direction of the first axis. The opposite ends of the fixing member are respectively inserted into the first limiting structure and the second limiting structure.

At the same time, the secondary pin connected to the secondary coil passes through the fixing hole of the fixing member, thereby fixing the secondary pin and making the secondary pin less prone to deformation under external force. This facilitates the precise connection between the secondary pin and the circuit board, improves the performance of the transformer, and further enhances the production efficiency and product stability of the whole machine.

The first limiting part is disposed on the side of the first partition part facing away from the second partition part along the direction of the first axis and is spaced apart from the first partition part. Both the first limiting part and the first partition part are disposed around the central columnar part. A secondary winding groove is formed between the first limiting part and the first partition part. The first limiting part is provided with a first limiting space.

[0012] Furthermore, the skeleton body also includes a second limiting part, which is connected to the outer wall of the central columnar part. The second limiting part is disposed on the side of the second partition part opposite to the first partition part along the direction of the first axis and is spaced apart from the second partition part. Both the second limiting part and the second partition part are disposed around the central columnar part, and a primary winding groove for accommodating the primary coil is formed between the second limiting part and the second partition part.

[0036] Example 1

[0037] Combination Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a transformer frame, including a frame body 10 and a fixing member 20. The frame body 10 has a first axis 11 and is provided with a secondary winding groove 12, a first limiting structure and a second limiting structure. The secondary winding groove 12 is arranged around the first axis 11 and is used to accommodate a secondary coil 30 connected with a secondary pin 40. The first limiting structure and the second limiting structure are distributed on opposite sides of the secondary winding groove 12 along the direction of the first axis 11. The opposite ends of the fixing member 20 are respectively inserted into the first limiting structure and the second limiting structure. The fixing member 20 is provided with a fixing hole 211 for the secondary pin 40 to pass through.

[0038] In use, the secondary coil 30 is installed in the secondary winding groove 12 of the frame body 10, and the two ends of the fixing member 20 are respectively inserted into the first limiting structure and the second limiting structure of the frame body 10 to fix the fixing member 20. At the same time, the secondary pin 40 connected to the secondary coil 30 passes through the fixing hole 211 of the fixing member 20, which can fix the secondary pin 40 and make it less likely to deform under external force. This is conducive to the precise docking of the secondary pin 40 with the circuit board, improves the performance of the transformer, and further improves the production efficiency and product stability of the whole machine.

[0039] It should be noted that the fastener 20 can be inserted into the first limiting structure in two ways: either the fastener 20 is inserted into the first limiting structure, or the first limiting structure is inserted into the fastener 20. In the former case, the first limiting structure is a space, such as a groove or hole, and one end of the fastener 20 is inserted into this space. In the latter case, the first limiting structure is a protrusion, and one end of the fastener 20 has a space, such as a groove or hole, into which the first limiting structure is inserted. Similarly, the fastener 20 can be inserted into the second limiting structure in two ways: either the fastener 20 is inserted into the second limiting structure, or the second limiting structure is inserted into the fastener 20. In the former case, the second limiting structure is a space, such as a groove or hole, and one end of the fastener 20 is inserted into this space. In the latter case, the second limiting structure is a protrusion, and one end of the fastener 20 has a space, such as a groove or hole, into which the second limiting structure is inserted.

[0040] Both the secondary coil 30 and the secondary pin 40 can be made of multi-strand enameled copper wire with a circular cross-section. The fixing hole 211 can be correspondingly set as a circular hole, and the radius of the fixing hole 211 is adapted to the radius of the secondary pin 40 to enhance the fixing effect on the secondary pin 40. The fixing hole 211 can also be set as an ellipse, and the elliptical fixing hole 211 can allow two or more secondary pins 40 to pass through simultaneously. The number of fixing holes 211 is not limited and depends on the actual situation. For example, Figure 2 The number of fixing holes 211 shown is three, arranged in a row. The fixing holes 211 on both sides are round holes, each allowing one secondary pin 40 to pass through, while the fixing hole 211 in the middle is an elliptical hole, allowing two secondary pins 40 to pass through simultaneously. The end of the secondary pin 40 away from the secondary coil 30 extends out of the fixing hole 211 for easy connection to the circuit board.

[0041] In existing technologies, the common method to address the issue of deformation of the secondary pin 40 is to directly replace the materials of the secondary coil 30 and the secondary pin 40, such as using copper bars or copper sheets instead of traditional enameled copper wire. However, using copper bars or copper sheets to manufacture the secondary coil 30 and the secondary pin 40 is costly and requires a redesign of the frame body 10, further increasing the transformer's manufacturing cost. In contrast, the secondary coil 30 and the secondary pin 40 in this application are made using traditional enameled copper wire, and the secondary pin 40 is fixed by the fixing component 20, thus solving the problem of deformation of the secondary pin 40. This eliminates the need to replace the materials of the secondary coil 30 and the secondary pin 40, thereby avoiding the increased costs associated with replacing the materials of the secondary coil 30 and the secondary pin 40.

[0042] Furthermore, such as Figure 2As shown, the fixing component 20 is also provided with heat dissipation holes 212. The heat dissipation holes 212 serve to dissipate heat, allowing the heat generated within the transformer frame during operation to be released into the outside air. The number of heat dissipation holes 212 is not limited and can be determined based on actual conditions. The shape of the heat dissipation holes 212 can be square, which provides good heat dissipation and is easy to manufacture.

[0043] Furthermore, combined Figure 3 and Figure 4 As shown, the first limiting structure is the first limiting space 13, and the second limiting structure is the second limiting space 14. The fixing member 20 includes a fixing part 21, a first insertion part 22, and a second insertion part 23. A fixing hole 211 is provided in the fixing part 21. The first insertion part 22 and the second insertion part 23 are respectively provided at opposite ends of the fixing part 21. The first insertion part 22 is inserted into the first limiting space 13, and the second insertion part 23 is inserted into the second limiting space 14. During installation, the first insertion part 22 is inserted into the first limiting space 13, and the second insertion part 23 is inserted into the second limiting space 14, thereby fixing the fixing member 20. At the same time, the secondary pin 40 passes through the fixing hole 211 of the fixing part 21, thereby fixing the secondary pin 40. Specifically, the fixing part 21, the first insertion part 22, and the second insertion part 23 can be integrally formed or manufactured separately and then assembled. The fixing part 21 can be a flat plate structure, which is simple in structure and facilitates the manufacture of the fixing hole 211. To improve the connection stability and reliability between the fastener 20 and the frame body 10, an appropriate amount of adhesive can be added to the first limiting space 13 to bond and fix the first insertion part 22 to the first limiting space 13. Similarly, an appropriate amount of adhesive can be added to the second limiting space 14 to bond and fix the second insertion part 23 to the second limiting space 14. The first limiting space 13 and the second limiting space 14 can be grooves or holes.

[0044] Furthermore, combined Figure 3 and Figure 4 As shown, an arc-shaped protrusion 1611 is provided in the second limiting space 14, and an arc-shaped groove 231 is provided in the second insertion part 23 to cooperate with the arc-shaped protrusion 1611. Based on the second insertion part 23 being inserted into the second limiting space 14, by providing the arc-shaped protrusion 1611 and the arc-shaped groove 231, the arc-shaped protrusion 1611 is inserted into the arc-shaped groove 231, which makes the connection between the fastener 20 and the frame body 10 tighter and enhances the fixing effect of the fastener 20.

[0045] Furthermore, such as Figure 3As shown, the skeleton body 10 includes a central columnar portion 161, a first partition portion 163, and a second partition portion 164. The central columnar portion 161 has a first axis 11. The first partition portion 163 and the second partition portion 164 are both connected to the outer wall surface of the central columnar portion 161 and are arranged sequentially at intervals along the direction of the first axis 11. A second limiting space 14 is formed between the first partition portion 163 and the second partition portion 164. A second insertion portion 23 is provided on the side of the fixing portion 21 facing the first axis 11. By providing the first partition portion 163 and the second partition portion 164 on the outer wall surface of the central columnar portion 161, and making the first partition portion 163 and the second partition portion 164 spaced apart in the direction of the first axis 11, a second limiting space 14 can be formed between the first partition portion 163 and the second partition portion 164. When the second insertion part 23 is inserted into the second limiting space 14, the first partition part 163 and the second partition part 164 cooperate to limit the second insertion part 23 in the direction of the first axis 11, thereby preventing the fixing member 20 from moving along the direction of the first axis 11. Combined with the fixing effect of the first insertion part 22 and the first limiting space 13, a stable connection between the fixing member 20 and the frame body 10 can be achieved. Specifically, the first partition part 163 and the second partition part 164 can be annular flat plate structures, which have the advantages of simple structure, easy manufacturing, and low manufacturing cost. They can also provide a flat limiting plane for the secondary coil 30. The first partition part 163, the second partition part 164, and the central column part 161 can be integrally formed or manufactured separately and then assembled. The second insertion part 23 is correspondingly set as a flat plate structure, which can fit snugly with the plate-shaped first partition part 163 and the second partition part 164, enhancing the fixing effect.

[0046] Furthermore, combined Figure 3 and Figure 4 As shown, the outer wall of the central columnar portion 161 forms an arc-shaped protrusion 1611 corresponding to the second limiting space 14, and the second insertion portion 23 is provided with an arc-shaped groove 231 that mates with the arc-shaped protrusion 1611. With the second insertion portion 23 inserted into the second limiting space 14, the arc-shaped protrusion 1611 and the arc-shaped groove 231, allowing the arc-shaped protrusion 1611 to insert into the arc-shaped groove 231, enable a tighter connection between the fixing member 20 and the frame body 10, enhancing the fixing effect of the fixing member 20, and making the transformer structure more compact, facilitating transformer assembly. Specifically, the central columnar portion 161 is cylindrical, and its outer wall can directly serve as the arc-shaped protrusion 1611. The second insertion portion 23 is an arc-shaped flat plate structure, and its side facing the center can form an arc-shaped groove 231.

[0047] Furthermore, such as Figure 3As shown, the skeleton body 10 includes a first limiting part 162, which is connected to the outer wall surface of the central columnar part 161. The first limiting part 162 is disposed along the direction of the first axis 11 on the side of the first partition part 163 facing away from the second partition part 164 and is spaced apart from the first partition part 163. Both the first limiting part 162 and the first partition part 163 are disposed around the central columnar part 161. A secondary winding groove 12 is formed between the first limiting part 162 and the first partition part 163. The first limiting part 162 is provided with a first limiting space 13. By providing the first limiting part 162 on the outer wall of the central columnar part 161 and distributing the first limiting part 162 along the direction of the first axis 11 on the side of the first partition part 163 facing away from the second partition part 164 and spaced apart from the first partition part 163, a secondary winding groove 12 surrounding the central columnar part 161 can be formed between the first limiting part 162 and the first partition part 163. When installing the secondary coil 30, it is wound around the central columnar portion 161. The first limiting portion 162 and the first separating portion 163 cooperate to limit the secondary coil 30 in the direction of the first axis 11, preventing the secondary coil 30 from moving along the direction of the first axis 11. By providing a first limiting space 13 in the first limiting portion 162, the first limiting space 13 and the second limiting space 14 can be distributed on opposite sides of the secondary winding groove 12 along the direction of the first axis 11.

[0048] Furthermore, combined Figure 2 and Figure 3 As shown, the first limiting part 162 includes a first limiting plate 1621 and a first limiting seat 1622. The first limiting plate 1621 is connected to the end of the central columnar part 161. A secondary winding groove 12 is formed between the first limiting plate 1621 and the first separating part 163. The first limiting seat 1622 is disposed on the side of the first limiting plate 1621 facing away from the first separating part 163. A first limiting space 13 is provided on the side of the first limiting seat 1622 facing away from the first axis 11. The first insertion part 22 is disposed on the side of the fixing part 21 facing the first axis 11. The first limiting plate 1621 has a flat plate structure, which has the advantages of simple structure, easy manufacturing and low manufacturing cost, and can provide a flat limiting plane for the secondary coil 30. The first limiting plate 1621 and the central columnar part 161 can be integrally formed or manufactured separately and then assembled. The first limiting seat 1622 and the first limiting plate 1621 can be integrally formed or manufactured separately and then assembled.

[0049] Furthermore, combined Figure 3 and Figure 4As shown, the size of the first limiting space 13 is reduced towards the first axis 11, and the shape of the first insertion part 22 is adapted to the shape of the first limiting space 13. By reducing the size of the first limiting space 13 towards the first axis 11, it is easier for the first insertion part 22 to be inserted into the first limiting space 13. The shape of the first insertion part 22 is adapted to the shape of the first limiting space 13, that is, the size of the first insertion part 22 is also reduced towards the first axis 11, so that the first insertion part 22 can fit against the first limiting seat 1622, thereby enhancing the fixing effect on the fastener 20.

[0050] Furthermore, such as Figure 3 As shown, the first limiting seat 1622 has a supporting surface 1624, which is disposed away from the first partition 163. The first insertion part 22 of the fastener 20 is inserted into the first limiting space 13 and disposed on the supporting surface 1624, thereby supporting the fastener 20.

[0051] Furthermore, combined Figure 2 and Figure 3 As shown, the central columnar portion 161 has a through hole 1612 for the magnetic core 70 to pass through. The through hole 1612 extends along the direction of the first axis 11. The outer periphery of the magnetic core 70 has a locking groove 71. The first limiting seat 1622 has a locking protrusion 1623 on the side facing the first axis 11 for engaging with the locking groove 71. The first limiting seat 1622 has two functions: firstly, it forms a first limiting space 13 on the side facing away from the first axis 11 for engaging with the first insertion portion 22; secondly, it forms a locking protrusion 1623 on the side facing the first axis 11. By inserting the locking protrusion 1623 into the locking groove 71 of the magnetic core 70, the magnetic core 70 can be positioned, preventing the magnetic core 70 from rotating within the through hole 1612. Specifically, the first limiting seat 1622 is V-shaped, so that a protrusion structure and a groove structure can be formed on its opposite sides respectively. The protrusion structure is the locking protrusion 1623, and the groove structure is the first limiting space 13.

[0052] Furthermore, combined Figure 2 and Figure 3As shown, the skeleton body 10 also includes a second limiting part 165, which is connected to the outer wall surface of the central columnar part 161. The second limiting part 165 is disposed along the direction of the first axis 11 on the side of the second partition part 164 facing away from the first partition part 163 and is spaced apart from the second partition part 164. The second partition part 164 and the second limiting part 165 are both disposed around the central columnar part 161. A primary winding groove 15 for accommodating the primary coil 50 is formed between the second partition part 164 and the second limiting part 165. By providing a second limiting part 165 on the outer wall surface of the central columnar portion 161, and arranging the second limiting part 165 along the direction of the first axis 11 on the side of the second partition portion 164 facing away from the first partition portion 163, the second limiting part 165 and the second partition portion 164 are spaced apart, and the second limiting part 165 and the second partition portion 164 are arranged around the central columnar portion 161, thereby forming a primary winding groove 15 surrounding the central columnar portion 161. When installing the primary coil 50, the primary coil 50 is wound around the central columnar portion 161. The cooperation of the second limiting part 165 and the second partition portion 164 can limit the primary coil 50 in the direction of the first axis 11, preventing the primary coil 50 from moving along the direction of the first axis 11. Specifically, the primary coil 50 is connected to a primary pin 60, and the second limiting part 165 is also used to fix the primary pin 60.

[0053] Furthermore, such as Figure 3 As shown, the second limiting part 165 includes a second limiting plate 1651 and a second limiting seat 1652. The second limiting plate 1651 is connected to the end of the central columnar part 161 away from the first limiting plate 1621. A primary winding groove 15 is formed between the second limiting plate 1651 and the second separating part 164. The second limiting seat 1652 is disposed on the side of the second limiting plate 1651 facing away from the second separating part 164 and is used to fix the primary pin 60. The second limiting plate 1651 has a plate-like structure, which has the advantages of simple structure, easy manufacturing and low manufacturing cost, and can provide a flat supporting plane for the primary coil 50. The second limiting plate 1651 and the second limiting seat 1652 can be integrally formed or manufactured separately and then assembled.

[0054] Furthermore, there are two magnetic cores 70, which are respectively inserted into the two ends of the through hole 1612. Both magnetic cores 70 are provided with a locking groove 71. The second limiting seat 1652 also has a locking protrusion 1623 on the side facing the first axis 11. The locking protrusion 1623 of the first limiting seat 1622 and the locking protrusion 1623 of the second limiting seat 1652 are respectively inserted into the locking grooves 71 of the two magnetic cores 70, thereby realizing the positioning of the two magnetic cores 70.

[0055] Example 2

[0060] Example 3

[0061] Combination Figure 1 and Figure 2 As shown, this embodiment provides a transformer, including a secondary coil 30, a secondary pin 40, and a transformer frame provided in Embodiment 1. The secondary coil 30 is housed in the secondary winding slot 12, and the secondary pin 40 is connected to the secondary coil 30. The secondary pin 40 passes through a fixing hole 211.

[0062] The transformer frame provided in Embodiment 1 is adopted. The fixing member 20 is fixed by inserting both ends of the fixing member 20 into the first limiting space 13 and the second limiting space 14 of the frame body 10, respectively. At the same time, the secondary pin 40 connected to the secondary coil 30 passes through the fixing hole 211 of the fixing member 20, thereby fixing the secondary pin 40. This makes the secondary pin 40 less prone to deformation under external force, which is conducive to the precise docking of the secondary pin 40 with the circuit board, improving the performance of the transformer, and further improving the production efficiency and product stability of the whole machine.

[0063] Furthermore, the transformer also includes a primary coil 50 and a magnetic core 70. The primary coil 50 is housed in the primary winding slot 15, and the primary pin 60 connected to the primary coil 50 is fixed on the second limiting seat 1652.
