[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] See Figure 1 An embodiment of this application provides a current transformer, including a current transformer body 10, a conductive element 20, and a mounting bracket 30. The mounting bracket 30 is used to mount the conductive element 20 to the current transformer body 10.

[0035] See Figure 4 The transformer body 10 is provided with a through hole 111, which penetrates the transformer body 10 along a first direction. For ease of understanding, S is used to represent the first direction, which is the thickness direction of the transformer body 10.

[0036] Optionally, see Figure 4 The through hole 111 is located in the middle of the transformer body 10.

[0037] Of course, in other embodiments, the through hole 111 may also be provided on the upper or lower part of the transformer body 10, and is not limited thereto.

[0038] It should be noted that the shape of the through hole 111 can be set according to actual needs, and no specific limitation is made here. Optionally, the cross-sectional shape of the through hole 111 can be circular, elliptical, or square, etc.

[0039] See Figure 1 and Figure 4 The conductive element 20 passes through the through hole 111. Furthermore, the mounting bracket 30 is disposed in the through hole 111 and is connected to the transformer body 10 and the conductive element 20.

[0040] During assembly, the conductive element 20 is passed through the through hole 111, and then the mounting bracket 30 is pushed into the through hole 111 in the first direction, so that the mounting bracket 30 is connected to the transformer body 10 and the conductive element 20, thus the conductive element 20 can be installed on the transformer body 10.

[0041] In one embodiment, see Figure 1 and Figure 7 The mounting bracket 30 has a first side surface 32, which is close to the conductive element 20. The mounting bracket 30 is provided with a first mounting groove 31, the opening of which is located on the first side surface 32.

[0042] Further, see Figure 6 The conductive element 20 passes through the first mounting groove 31.

[0043] Because the opening of the first mounting groove 31 is located on the first side 32 of the mounting bracket 30, during assembly, the conductive component 20 can be placed in the first mounting groove 31 through the opening of the first mounting groove 31. This allows the first mounting groove 31 to fix not only elongated conductive components 20, but also U-shaped conductive components 20. This not only improves the efficiency of installing the conductive component 20 on the transformer body 10, but also allows the mounting bracket 30 to fix conductive components 20 of different shapes, thus expanding the applicability of the mounting bracket 30.

[0044] In one embodiment, see Figure 7 In the first direction, the mounting bracket 30 has two first end faces 33.

[0045] Further, see Figure 7 and Figure 8 The first mounting groove 31 extends through the two first end faces 33 along the first direction, so that a first through outlet 331 is formed on each of the two first end faces 33. During assembly, after the mounting bracket 30 is pushed into the through hole 111, the middle part of the conductive element 20 is placed in the first mounting groove 31 through the groove opening of the first mounting groove 31, and the two ends of the conductive element 20 respectively pass through the two first through outlets 331 to the outside of the first mounting groove 31.

[0046] In one embodiment, see Figure 6 The first mounting groove 31 has a first connecting portion 35 on its groove wall, and the conductive component 20 has a second connecting portion 21. The first connecting portion 35 and the second connecting portion 21 are connected and cooperate to restrict the movement of the conductive component 20 in the first direction. In this way, when the mounting bracket 30 is assembled in the through hole 111, the first connecting portion 35 and the second connecting portion 21 are connected, realizing the connection between the conductive component 20 and the mounting bracket 30. This can restrict the movement of the conductive component 20 in the first direction and ensure that the conductive component 20 can be accurately mounted on the circuit board.

[0047] In one embodiment, refer to icon 7 and Figure 8 The first mounting groove 31 has a first groove wall 311 and a second groove wall 312. The first groove wall 311 is disposed opposite to the groove opening. There are two second groove walls 312, which are disposed opposite to each other and located between the first groove wall 311 and the first side surface 32.

[0048] Optionally, see Figure 6 and Figure 8 The first connecting part 35 is provided on the second groove wall 312, and the second connecting part 21 is provided on the side of the conductive member 20 facing the first connecting part 35.

[0049] It should be noted that the number of the first connecting portion 35 and the second connecting portion 21 can be set according to actual needs. Optionally, one of the second groove walls 312 is provided with the first connecting portion 35, and the conductive member 20 is provided with the second connecting portion 21 on the side facing the first connecting portion 35. Optionally, both second groove walls 312 are provided with the first connecting portion 35, and the conductive member 20 is provided with the second connecting portion 21 on both opposite sides.

[0050] Of course, in other embodiments, the first connecting part 35 may also be provided on the first groove wall 311, and the second connecting part 21 may be provided on the side of the conductive member 20 facing the first groove wall 311.

[0051] In one embodiment, see Figure 6 , Figure 8 and Figure 9 One of the first connecting portion 35 and the second connecting portion 21 is provided with a connecting buckle 351, and the other of the first connecting portion 35 and the second connecting portion 21 is provided with an assembly groove 211, in which the connecting buckle 351 is engaged. In this way, the convenience and reliability of connecting the conductive component 20 and the mounting bracket 30 can be improved.

[0052] Of course, in other embodiments, one of the first connecting portion 35 and the second connecting portion 21 is provided with a connecting post, and the other of the first connecting portion 35 and the second connecting portion 21 is provided with a connecting hole, with the connecting post and the connecting hole being interference fit. Alternatively, the first connecting portion 35 and the second connecting portion 21 are mortised and tenoned.

[0053] In one embodiment, the current transformer body 10 is provided with a first positioning part 133, and the conductive element 20 is provided with a second positioning part 22. The first positioning part 133 and the second positioning part 22 are positioned and engaged. During assembly, the conductive element 20 passes through the through hole 111, and the first positioning part 133 and the second positioning part 22 are positioned and engaged to achieve positioning of the conductive element 20 and the current transformer body 10, preventing the conductive element 20 from moving during the insertion of the mounting bracket 30 into the through hole 111. This facilitates precise connection between the conductive element 20 and the mounting bracket 30, thereby improving the reliability of the conductive element 20 installed on the current transformer body 10.

[0054] Optionally, one of the first positioning part 133 and the second positioning part 22 is provided with an assembly groove 211, and the other of the first positioning part 133 and the second positioning part 22 is provided with a positioning protrusion 1331, which is disposed within the assembly groove 211. In this way, the convenience of positioning the conductive component 20 can be improved.

[0055] In one embodiment, see Figure 8 The first connecting part 35 is provided with a connecting buckle 351. Optionally, the connecting buckle 351 is provided on the second groove wall 312.

[0056] Further, see Figure 5 The first positioning part 133 is provided with a positioning protrusion 1331, which is located inside the through hole 111.

[0057] Further, see Figure 2 , Figure 3 and Figure 6 The second connecting part 21 overlaps with the second positioning part 22. An assembly groove 211 is provided at the location of the second connecting part 21 and the second positioning part 22. The opening of the assembly groove 211 is located on the side of the conductive member 20 facing the connecting buckle 351. The assembly groove 211 penetrates the conductive member 20 along the depth direction of the first mounting groove 31. The connecting buckle 351 and the positioning protrusion 1331 are both located within the assembly groove 211. This facilitates the insertion of the connecting buckle 351 into the assembly groove 211, improving the ease of assembly between the connecting buckle 351 and the assembly groove 211.

[0058] It should be noted that the depth direction of the first mounting groove 31 refers to the direction from the first groove wall 311 of the first mounting groove 31 to the groove opening.

[0059] In one embodiment, see Figure 4 and Figure 5 A mounting base 13 is provided inside the through hole 111, and the mounting base 13 is connected to the hole wall of the through hole 111.

[0060] Optionally, the mounting base 13 is semi-cylindrical. It is understood that the mounting base 13 and the mounting bracket 30 can be mated to form a cylinder.

[0061] Further, see Figure 5The mounting base 13 has a second side surface 132, with the first side surface 32 opposite to the second side surface 132. The mounting base 13 is provided with a second mounting groove 131, the opening of which is located on the second side surface 132. The mounting base 13 can mate with the mounting bracket 30 so that the first mounting groove 31 and the second mounting groove 131 form a mounting hole through which the conductive element 20 passes. The groove walls of the first mounting groove 31 and the second mounting groove 131 can restrict the movement of the conductive element 20 in a direction perpendicular to the first direction. Simultaneously, the connecting buckle 351, in cooperation with the assembly groove 211, can further restrict the movement of the conductive element 20 in the first direction, thus improving the reliability of the conductive element 20's installation on the transformer body 10.

[0062] In this embodiment, see Figure 5 The first positioning part 133 is disposed on the groove wall of the second mounting groove 131.

[0063] In one embodiment, see Figure 5 In the first direction, the mounting base 13 has two opposing second end faces 134.

[0064] Further, see Figure 5 The second mounting groove 131 extends through the two second end faces 134 of the mounting base 13 along the first direction, forming second through outlets 1341 on the two second end faces 134 of the mounting base 13. During assembly, the conductive element 20 is placed in the first mounting groove 31, with the middle part of the conductive element 20 passing through the opening of the second mounting groove 131 and the two ends of the conductive element 20 respectively passing through the two second through outlets 1341 of the mounting base 13 and exiting the second mounting groove 131.

[0065] In one embodiment, see Figure 7 The mounting bracket 30 has an outer peripheral surface 34, and the outer peripheral surface 34 is provided with a protruding rib 36, which is connected to the wall of the through hole 111. During assembly, the mounting bracket 30 is pushed into the through hole 111 along the first direction, and the protruding rib 36 abuts against the wall of the through hole 111. In this way, the mounting bracket 30 and the conductive component 20 can be tightly fitted in the through hole 111, and the mounting bracket 30 can be easily installed.

[0066] In one embodiment, see Figure 7 At least two ribs 36 are provided, all of which extend along a first direction and are spaced apart circumferentially around the mounting bracket 30. Since the ribs 36 extend along the first direction, i.e., the extending direction of the ribs 36 is consistent with the pushing direction of the mounting bracket 30, the ease of installation of the mounting bracket 30 is further improved. Because at least two ribs 36 are provided, the mounting bracket 30 and the conductive element 20 can be better fitted together within the through hole 111.

[0067] In one embodiment, see Figure 1, Figure 7 and Figure 8 One of the first end faces 33 of the mounting bracket 30 is provided with a flange 332, which is located outside the through hole 111. By providing a flange 332 on one of the end faces of the mounting bracket 30, the diameter of the end face is made larger than the diameter of the through hole 111.

[0068] During assembly, the end of the mounting bracket 30 facing away from the flange 332 is inserted into the through hole 111. Then, the mounting bracket 30 is pushed along the first direction until the flange 332 is in contact with the side of the transformer body 10 in the first direction. In this way, by providing the flange 332 on the end face of the mounting bracket 30, the mounting bracket 30 can be limited, ensuring that the mounting bracket 30 can be accurately connected and engaged with the conductive component 20.

[0069] In one embodiment, the mounting bracket 30 has a hollow structure. Optionally, the hollow structure is a hollow groove 37 or a hollow hole. In this way, by designing the mounting bracket 30 with a hollow structure, the material required for the mounting bracket 30 can be reduced, the cost can be reduced, the weight of the mounting bracket 30 can be reduced, and the mounting bracket 30 can be easily processed and shaped.

[0070] Optionally, see Figure 8 The first groove wall 311 is provided with a hollow groove 37, which is recessed in a direction away from the opening of the first mounting groove 31. Furthermore, there are at least two hollow grooves 37, all of which extend along the first direction and are arranged at intervals in a direction perpendicular to the first direction.

[0071] Optionally, a hollowed-out groove 37 is provided in the area between the first groove wall 311 and the outer peripheral surface 34 of the mounting bracket 30.

[0072] Of course, in other embodiments, the hollowed-out groove 37 may also be provided on either of the two first end faces 33 of the mounting bracket 30.

[0073] In one embodiment, the transformer body 10 includes a housing 11, a magnetic core, and a coil. The housing 11 has a receiving cavity, the magnetic core is disposed in the receiving cavity, and the coil is wound around the magnetic core.

[0074] Further, see Figure 1 and Figure 2 The transformer body 10 also includes a terminal block 12 for electrical connection to a circuit board, the terminal block 12 being electrically connected to the coil. Optionally, the extending direction of the terminal block 12 is parallel to the extending direction of the end of the conductive element 20.

[0075] During assembly, the conductive component 20 is fixed to the transformer body 10 using the mounting bracket 30, which facilitates the installation of the conductive component 20 and the wiring terminal 12 on the circuit board.

[0076] This application also provides an electronic device including any of the aforementioned current transformers.

[0077] In the aforementioned electronic device, the opening of the first mounting groove 31 is located on the first side 32 of the mounting bracket 30. During assembly, the conductive component 20 can be positioned in the first mounting groove 31 through the opening of the first mounting groove 31. This allows the first mounting groove 31 to fix not only elongated conductive components 20 but also U-shaped conductive components 20. This not only improves the convenience of connecting the conductive component 20 to the mounting bracket 30 but also allows the mounting bracket 30 to fix conductive components 20 of different shapes, thus expanding the applicability of the mounting bracket 30.
