[0042] like Figures 1 to 4 As shown, this embodiment provides a wiring structure for a coil winding, which includes a coil frame 1, a coil winding 2, and a first conductive sheet 3. The coil frame 1 has a first mounting groove 11. A first positioning groove 12 is provided on the first sidewall 111 of the first mounting groove 11, extending from the opening to the bottom of the groove. An clearance opening 13 is provided on the sidewall of the first positioning groove 12. A first limiting member 14 is provided at the bottom of the first mounting groove 11. The coil winding 2 is wound on the coil frame 1. The first conductive sheet 3 includes a first conductive sheet body 31, a first connecting part 32, a first plug-in part 33, and a first winding part 34. The first conductive sheet body 31 is placed in the first mounting groove 11. The first connecting part 32 is connected to the first conductive sheet body 31 and is used to connect to an external power source. The first conductive sheet body 31 is provided with a first limiting hole 311. A first limiting member 14 passes through the first limiting hole 311 and is riveted to the first conductive sheet body 31. One end of the first plug-in part 33 is inserted into the first positioning groove 12, and the other end of the first plug-in part 33 passes through an avoidance opening 13 and is connected to the first conductive sheet body 31. The first winding part 34 is connected to the first conductive sheet body 31 and is connected to the inlet or outlet end of the coil winding 2.

[0043] The first limiting member 14 passes through the first limiting hole 311 and is riveted to the first conductive sheet body 31. It defines the position of the first conductive sheet 3 in the direction from the opening to the bottom of the first mounting groove 11. The first positioning groove 12 extends from the opening to the bottom of the first mounting groove 11. The first insertion part 33 is inserted into the first positioning groove 12. On a plane perpendicular to the direction from the opening to the bottom of the first mounting groove 11, the first positioning groove 12 and the first insertion part 33 cooperate to define the position of the first conductive sheet 3. The position of the first conductive sheet 3 is defined in different directions, and the stability of fixing the first conductive sheet 3 is good, thereby ensuring the reliability of the connection between the inlet or outlet end of the coil winding 2 and the first winding part 34. In addition, while the first plug part 33 is inserted into the first positioning groove 12, the avoidance part plays the role of avoiding the first plug part 33. The first limiting member 14 passes through the first limiting hole 311, and then the first limiting member 14 is riveted, which simplifies the installation structure of the first conductive sheet 3 and facilitates the installation of the first conductive sheet 3.

[0044] In a conventional coil winding structure, the first conductive sheet 3 is connected to the coil winding 2 and also to an external power source, which supplies power to the coil winding 2 through the first conductive sheet 3. The coil winding 2 has an inlet end and an outlet end, and two first conductive sheets 3 are correspondingly provided. The coil frame 1 has two first mounting slots 11, and the first conductive sheets 3 are installed in the first mounting slots 11. Both first conductive sheets 3 are connected to the external power source; the first winding portion 34 of one first conductive sheet 3 is connected to the inlet end of the coil winding 2, and the first winding portion 34 of the other first conductive sheet 3 is connected to the outlet end of the coil winding 2.

[0045] The coil frame 1 is also provided with a wiring groove, which is connected to the first mounting groove 11. The inlet or outlet end of the coil winding 2 passes through the wiring groove and is then connected to the first winding part 34 of the first conductive sheet 3.

[0046] In some embodiments, the coil frame 1 includes a first frame plate 19, a frame support shaft 101, and a second frame plate 102 connected in sequence. A first mounting groove 11 is disposed on the first frame plate 19, and the coil winding 2 is wound on the frame support shaft 101. As described above, there are two first mounting grooves 11, which are disposed at both ends of the first frame plate 19.

[0047] The coil winding 2 includes enameled wire, which is wound around the skeleton support shaft 101. The enameled wire has an inlet end and an outlet end.

[0048] In some embodiments, the first insertion portion 33 of the first conductive sheet 3 includes a first insertion plate 331 and a first connecting plate 332. One end of the first connecting plate 332 is connected to the first conductive sheet body 31, and the other end of the first connecting plate 332 is smoothly connected to one end of the first insertion plate 331. The first connecting plate 332 sets the first insertion plate 331 and the first conductive sheet body 31 at an angle. The first insertion plate 331 is inserted into the first positioning groove 12, and the two opposite sides of the first insertion plate 331 abut against the groove wall of the first positioning groove 12. The first connecting plate 332 has a clearance opening 13. When the first conductive sheet body 31 is placed in the first mounting groove 11, the first insertion plate 331 is inserted into the first positioning groove 12. The first insertion plate 331 abuts against the groove wall of the first positioning groove 12, which plays a role in pre-positioning the first insertion plate 331.

[0049] Optionally, such as Figure 5 As shown, the side of the first plug plate 331 that abuts against the groove wall of the first positioning groove 12 is a flat surface, a sawtooth surface, or an arc-shaped surface, which is not specifically limited here.

[0050] Combination Figure 3 , Figure 4 and Figure 6 As shown, the first winding portion 34 and the first insertion portion 33 are disposed on both sides of the first connecting portion 32. After the first conductive sheet body 31 is installed in the first mounting groove 11, the first winding portion 34 is disposed on the inner side, and the first insertion portion 33 is disposed on the outer side, shortening the length of the inlet or outlet end of the coil winding 2. One end of the first winding portion 34 is connected to the first conductive sheet body 31, and the other end of the first winding portion 34 is disposed at an angle to the first conductive sheet body 31. Both the first winding portion 34 and the first insertion plate 331 extend toward the same side of the first conductive sheet body 31. While the first conductive sheet body 31 is installed in the first mounting groove 11, the first insertion portion 33 is inserted into the first positioning groove 12. At the same time, the first winding portion 34 faces away from the coil frame 1, facilitating connection with the inlet or outlet end of the coil winding 2.

[0051] In some embodiments, such as Figures 5 to 7As shown, the first connecting portion 32 includes a first clamping piece 321 and a second clamping piece 322. Both the first clamping piece 321 and the second clamping piece 322 have an S-shaped structure. One end of the first clamping piece 321 is elastically connected to one end of the first conductive sheet body 31, and one end of the second clamping piece 322 is elastically connected to the other end of the first conductive sheet body 31. The other end of the second clamping piece 322 extends in the same direction and is flush with the other end of the first clamping piece 321. The portion of the first clamping piece 321 bent toward the second clamping piece 322 and the portion of the second clamping piece 322 bent toward the first clamping piece 321 cooperate to clamp the conductive component 100 connected to an external power source. The first clamping piece 321 and the second clamping piece 322 form an opening structure that facilitates the insertion of the conductive component 100. The elastic clamping of the conductive component 100 by the bent portions of the first clamping piece 321 and the second clamping piece 322 ensures the reliability of the connection between the first conductive sheet 321 and the conductive component 100.

[0052] Optionally, the first clamping piece 321 is disposed within the first mounting groove 11, and a first limiting protrusion 15 is provided within the first mounting groove 11 at a position opposite to the first sidewall 111. The second clamping piece 322 is constrained between the first sidewall 111 and the first limiting protrusion 15. The first sidewall 111 and the first limiting protrusion 15 limit the second clamping piece 322, ensuring the clamping force between the second clamping piece 322 and the first clamping piece 321, and preventing the second clamping piece 322 from shifting during the insertion of the conductive member 100 into the first clamping piece 321 and the second clamping piece 322.

[0053] In some embodiments, such as Figure 2 , Figure 8 and Figure 9 As shown, the coil frame 1 is also provided with a second mounting groove 16. The wiring structure of the coil winding also includes a second conductive piece 4 and a circuit board 5. The second conductive piece 4 and the circuit board 5 are disposed between the first winding part 34 and the coil winding 2. The second conductive piece 4 is disposed in the second mounting groove 16. The first winding part 34 is electrically connected to the circuit board 5, and the circuit board 5 is electrically connected to the second conductive piece 4. The second conductive piece 4 is connected to the inlet or outlet end of the coil winding 2. The external power supply is connected to the high-voltage circuit of the circuit board 5 through the first conductive piece 3. The low-voltage circuit on the circuit board 5 is connected to the high-voltage circuit. The high-voltage voltage is converted into a low-voltage voltage by the low-voltage circuit. The low-voltage circuit is connected to the coil winding 2 through the second conductive piece 4, thereby realizing the control of power consumption through the circuit board 5 and realizing the power supply function. The circuit board 5 and the second conductive piece 4 form an electronic coil winding structure. The second conductive piece 4 is an independent structure and can be selectively installed, so that the coil frame 1 of this structure can be adapted to both conventional coil winding structures and electronic coil winding structures.

[0054] The coil winding 2 has an inlet and an outlet end, and two second conductive plates 4 are correspondingly provided. The coil frame 1 has two second mounting slots 16, and the second conductive plates 4 are installed in the second mounting slots 16.

One second conductive plate 4 is connected to the inlet end of the coil winding 2, and the other second second conductive plate 4 is connected to the outlet end of the coil winding 2. The wiring groove on the coil frame 1 also communicates with the second mounting slots 16 to facilitate the connection of the inlet or outlet end of the coil winding 2 to the second conductive plate 4.

[0055] The second mounting slot 16 is provided on the first frame plate 19 of the coil frame 1. As described above, there are two second mounting slots 16, which are located in the middle of the first frame plate 19 and are positioned between the two first mounting slots 11.

[0056] Optionally, the second conductive sheet 4 includes a second conductive sheet body 41, a second winding portion 42, and a second connecting portion 43. The second conductive sheet body 41 is placed in the second mounting groove 16. The second conductive sheet body 41 is provided with a second limiting hole 411. The bottom of the second mounting groove 16 is provided with a second limiting member 17 and a third limiting member 18. The second limiting member 17 passes through the second limiting hole 411 and is riveted to the second conductive sheet body 41. The second winding portion 42 and the second connecting portion 43 are respectively connected to the second conductive sheet body 41. The second winding portion 42 is connected to the inlet or outlet end of the coil winding 2. The second connecting portion 43 is electrically connected to the circuit board 5. The second connecting portion 43 is connected to the third limiting member 18. The third limiting member 18 is used to limit the second connecting portion 43 in a plane perpendicular to the axis of the second limiting member 17. The second limiting member 17 is riveted to the second conductive sheet 4, and the second conductive sheet 4 is restricted in the axial direction of the second limiting member 17. The third limiting member 18 is used to limit the second connecting part 43 in a plane perpendicular to the axis of the second limiting member 17, thereby realizing the limitation of the position of the second conductive sheet 4 in different directions.

[0057] The second limiting member 17 is provided in multiple ways, and the second limiting hole 411 is provided one-to-one with the second limiting member 17. This can prevent the second conductive sheet 4 from rotating relative to the second limiting member 17, and facilitate the limiting connection between the third limiting member 18 and the second connecting part 43.

[0058] One end of the second connecting part 43 is connected at an angle to the second conductive sheet body 41, and the other end of the second connecting part 43 is provided with a insertion groove 431. The second conductive sheet body 41 is provided with an insertion hole 412, which communicates with the insertion groove 431, and the diameter of the insertion hole 412 is larger than the inner diameter of the insertion groove 431. The third limiting member 18 includes a first limiting plate 181 and a second limiting plate 182. One end of the first limiting plate 181 is perpendicularly connected to the middle of the second limiting plate 182. The second limiting plate 182 is inserted into the insertion hole 412, and the first limiting plate 181 is inserted into the insertion groove 431. The groove wall of the insertion groove 431 abuts against the first limiting plate 181. The second connecting part 43 and the third limiting member 18 cooperate to achieve limiting in a plane perpendicular to the axis of the second limiting member 17, and the structure is simple. While the second conductive sheet body 41 is installed in the second mounting groove 16, the second limiting plate 182 is inserted into the insertion hole 412, the second limiting member 17 passes through the second limiting hole 411, and the first limiting plate 181 is inserted into the insertion groove 431, thereby limiting the second conductive sheet body 41. The installation structure is simple and convenient for installing the second conductive sheet 4. Optionally, the insertion hole 412 and the insertion groove 431 are smoothly connected.

[0059] The groove wall of the insertion groove 431 that abuts against the first limiting plate 181 can be a flat surface, a sawtooth surface, or an arc surface, and no specific limitation is made here.
