[0002] In the prior art, in order to achieve a more reliable connection between the stator coil and the external coil of the stator core, a wire hook rack is usually provided. For example, utility model patent CN212381047U discloses a motor, including a terminal assembly for connecting or fixing the input end and the output end of the winding. An access slot for accessing the terminal assembly is provided on the stator core, and a bayonet is formed in the access slot, and the bayonet can be inserted into the terminal assembly. The terminal assembly includes an insert and a wire hook rack. The insert is made of insulating material and plays an insulating role. There are multiple wire hook racks, and the multiple wire hook racks are first installed on the insert and then installed in the bayonet through the insert. The number of parts of the stator core is large, resulting in the need to form a larger bayonet in the access slot, thereby increasing the circumferential size of the stator core, thereby increasing the circumferential size of the motor, and failing to meet the needs of electric tools such as electric drills, garden saws, and pruning saws that require a more compact motor. Utility Model Content

[0003] The utility model aims to provide a stator core to achieve miniaturization of the stator core.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a stator core, including a core body, an upper insulating frame, a lower insulating frame and a plurality of wire hooking frames, the core body is provided with a first flange portion in the circumferential direction, the first flange portion is provided with a plurality of mounting grooves corresponding to the plurality of wire hooking frames, the wire hooking frame includes an insulator and a conductive terminal, the insulator is installed in the mounting groove, the conductive terminal includes a wire hooking portion and a wire hanging portion with a positioning hole, the conductive terminal is fixedly installed on the insulator and has an insulating gap between the conductive terminal and the mounting groove.

[0005] After adopting the above technical scheme, the utility model has the following advantages: the wire hook frame includes an insulator and a conductive terminal, the insulator is installed in the installation groove, the conductive terminal is fixedly installed on the insulator and has an insulating gap with the installation groove, so as to realize the insulation of the conductive terminal and the installation groove, omit the insert, so that the wire hook frame can be directly installed on the installation groove, which not only reduces the number of parts of the stator core, but also helps to reduce the volume of the installation groove occupied by the wire hook frame, thereby reducing the size of the installation groove, and can also help to reduce the radial size of the stator core, thereby helping to reduce the circumferential size of the stator core, and improve the compactness of the stator core structure. Compared with multiple wire hook frames installed in one slot, the volume of the stator core can be miniaturized, and the provision of multiple installation slots can also separate the wire hook frames from each other, which is conducive to more reasonable routing of the stator coil on the wire hook frame.

[0006] Furthermore, the mounting groove is located in the radial direction of the core body and has an opening outward, the conductive terminal is arranged on the side of the insulator located at the opening, and at least part of the conductive terminal protrudes from the insulator, and the protruding part is suspended in the mounting groove to form an insulating gap between the conductive terminal and the mounting groove. With the above technical solution, the protruding part is suspended in the mounting groove to form an insulating gap between the conductive terminal and the mounting groove to achieve insulation, and the remaining conductive terminals installed on the insulator are insulated by the insulator and the mounting groove.

[0007] Furthermore, the wire hanging portion is arranged along the vertical extension of the insulator, and at least part of the wire hanging portion protrudes from the insulator, the positioning hole is arranged on the protruding portion, and the thickness of the protruding portion in the radial direction of the core body is less than the thickness of the insulator in the radial direction of the core body, so that an insulating gap is formed between the wire hanging portion and the bottom wall of the installation slot. With the above-mentioned technical solution, since the insulator is vertically installed on the stator core, the lateral size of the insulator is effectively reduced by extending the wire hanging portion along the vertical extension of the insulator, and the positioning hole is arranged on the protruding portion, which is convenient for external lead routing. Finally, the thickness of the protruding portion in the radial direction of the core body is less than the thickness of the insulator in the radial direction of the core body, so that an insulating gap is formed between the wire hanging portion and the bottom wall of the installation slot to achieve insulation.

[0008] Furthermore, the thickness of the insulator in the circumferential direction of the core body is greater than the thickness of the wire hanging part in the circumferential direction of the core body, so that an insulating gap is formed between the wire hanging part and the side wall of the installation slot. By adopting the above-mentioned technical solution, the thickness of the insulator in the circumferential direction of the core body is greater than the thickness of the wire hanging part in the circumferential direction of the core body, so that an insulating gap is formed between the wire hanging part and the side wall of the installation slot, so that an insulating gap is formed around the wire hanging part and the installation slot, which effectively improves the insulation effect and facilitates wiring.

[0009] Furthermore, the insulator is arranged vertically, the mounting groove is arranged vertically corresponding to the insulator, the insulator is vertically inserted into the mounting groove and fixed by means of an upper insulating frame and a lower insulating frame, the upper insulating frame is arranged at the upper part of the insulator, and the lower insulating frame is arranged at the lower part of the insulator. With the above technical solution, during assembly, after the insulator is vertically inserted into the mounting groove, the upper insulating frame and the lower insulating frame are installed on the core body, and the insulator is fixed at the same time, so that the wire hook frame is reliably fixed, and the assembly steps can also be simplified, which is convenient for assembly.

[0010] Furthermore, a positioning step is formed between the protruding portion of the wire hanging part and the insulator, a second flange portion is provided on the circumference of the upper insulating frame, a third flange portion is provided on the circumference of the lower insulating frame, the vertical length of the insulator is less than the vertical length of the mounting groove, the second flange portion abuts against one end of the insulator away from the positioning step, and the third flange portion is partially inserted into the mounting groove and abuts against the positioning step. The above technical solution is adopted to form a positioning step between the protruding portion of the wire hanging part and the insulator, so that the third flange portion is partially inserted into the mounting groove, which is conducive to reducing the axial size of the stator core.

[0011] Furthermore, the center line of the conductive terminal in the vertical direction coincides with the center line of the insulator in the vertical direction; or, an angle is provided between the center line of the conductive terminal in the vertical direction and the center line of the insulator in the vertical direction. The aforementioned technical solution is adopted to set the center line of the wire hanging part in the vertical direction to coincide with the center line of the insulator in the vertical direction, so that the wire hanging part is arranged parallel to the axial direction of the core body, which is conducive to making the radial dimension of the stator core more compact; or, an angle is provided between the center line of the conductive terminal in the vertical direction and the center line of the insulator in the vertical direction, so that the force direction of the conductive terminal tends to be consistent with the force direction of the stator coil, which is conducive to reducing the stress concentration area at the bottom of the conductive terminal, thereby facilitating the service life of the wire hook frame.

[0012] Furthermore, the slot of the installation slot in the radial direction of the core body is provided with a stop rib, and the stop rib cooperates with the insulator to limit the position.

[0039] Embodiment 1:

[0040] like Figures 1 to 8As shown, the embodiment of the utility model provides a stator core, including a core body 1, a stator coil 2 wound on the core body 1, a first flange portion 12 arranged on the circumference of the core body 1, and a plurality of wire hooking frames 5, the first flange portion 12 is provided with a plurality of vertically arranged mounting grooves 121 corresponding to the plurality of wire hooking frames 5, the wire hooking frame 5 includes an insulator 51 and a conductive terminal 52, the insulator 51 is installed in the mounting groove 121, and the end of the core body 1 is provided with an upper insulating frame 3 and a lower insulating frame 3. The upper insulating frame 3 is arranged at the upper part of the core body 1, and the lower insulating frame 4 is arranged at the lower part of the core body 1. The insulator 51 is vertically inserted into the mounting groove 121 and fixed by means of the upper insulating frame 3 and the lower insulating frame 4, so that the installation of the hooking frame 5 is more reliable, and the upper insulating frame 3 is provided with a wiring channel 31, and the core body 1 is provided with a winding channel 11. The conductive terminal 52 includes a hooking portion 521 and a hanging portion 522 with a positioning hole 5222. The hanging portion 522 is vertically arranged, and the hooking portion 521 is provided with a positioning hole 5222. After the frame 5 is installed to the corresponding installation groove 121, the stator coil 2 led out through the winding channel 11 passes through the wiring channel 31 and is fixed on the wire hooking part 521. The external coil is positioned and connected to the wire hanging part 522 through the positioning hole 5222, so as to facilitate the welding of the stator coil 2 and the external coil. Finally, the conductive terminal 52 is fixedly installed on the insulator 51 and has an insulating gap 6 with the installation groove 121, so as to realize the insulation effect of the conductive terminal 52 and the installation groove 121, and eliminate the insert, so that the wire hook frame 5 can be directly installed on the installation groove 121, which not only reduces the number of parts of the stator core, but also helps to reduce the volume of the installation groove 121 occupied by the wire hook frame 5, thereby reducing the size of the installation groove 121, and can also help to reduce the radial size of the stator core, thereby helping to reduce the circumferential size of the stator core, improve the compactness of the stator core structure, and, compared with multiple wire hook frames 5 installed in one slot, can better realize the miniaturization of the stator core.

[0041] It can be understood that the insulator 51 can also be inserted into the mounting groove 121 along the radial direction of the core body 1.

[0042] It should be noted that the first flange portion 12 and the core body 1 can be integrally formed or detachably installed.

[0043] It can be understood that the external coil can be a coil of a control board or a coil of a circuit board.

[0044] It can be understood that the wire hooking racks 5 can be provided with two, three, four or other suitable numbers.

[0045] It is understandable that the mounting groove 121 may also be directly disposed on the outer circumferential surface of the core body 1 .

[0046] Among them, multiple installation grooves 121 are arranged at intervals, and the wire hooking frame 5 includes an insulator 51 and a conductive terminal 52. The multiple wire hooking frames 5 are respectively located in separate installation grooves 121, which is conducive to isolating the stator coils 2 from each other and making the connection safer.

[0047] Furthermore, the first flange portion 12 has a structure that is larger inside and smaller outside in a direction from the center of the core body 1 to the edge, thereby further reducing the circumferential dimension of the stator core.

[0048] In order to further miniaturize the circumferential volume of the core body 1 , a plurality of mounting grooves 121 are arranged along the circumference of the core body 1 , which is beneficial to reducing the radial dimension of the core body 1 .

[0049] Furthermore, the vertical center line of the conductive terminal 52 coincides with the vertical center line of the insulator 51, so that after the wire hook frame 5 is installed in the mounting groove 121, the wire hanging portion 522 is arranged parallel to the axial direction of the core body 1, so that the wire hanging portion 522 fits the stator core more closely, which is beneficial to make the radial dimension of the stator core more compact.

[0050] Specifically, the mounting groove 121 is located in the radial direction of the core body 1 and has an opening 123 opened outwardly. The conductive terminal 52 is arranged on one side of the insulator 51 located at the opening 123, and at least part of the conductive terminal 52 protrudes from the insulator 51. The protruding part is suspended in the mounting groove 121 to form an insulating gap 6 between the conductive terminal 52 and the mounting groove 121 to achieve insulation. The remaining conductive terminal 52 installed on the insulator 51 is insulated by the insulator 51 and the mounting groove 121.

[0051] Among them, the wire hanging portion 522 is arranged along the vertical extension of the insulator 51, and at least part of the wire hanging portion 522 protrudes from the insulator 51, effectively reducing the lateral size of the insulator 51, and the positioning hole 5222 is arranged on the protruding portion 5221, which is convenient for the routing of external leads. Finally, the thickness of the protruding portion 5221 in the radial direction of the core body 1 is smaller than the thickness of the insulator 51 in the radial direction of the core body 1, so that an insulating gap 6 is formed between the wire hanging portion 522 and the bottom wall of the mounting groove 121 to achieve insulation.

[0052] Secondly, the thickness of the insulator 51 in the circumferential direction of the core body 1 is greater than the thickness of the wire hanging portion 522 in the circumferential direction of the core body 1, so that an insulating gap 6 is formed between the wire hanging portion 522 and the side wall of the installation groove 121, thereby forming an insulating gap 6 around the wire hanging portion 522 and the installation groove 121, effectively improving the insulation effect and facilitating wiring.

[0053] Furthermore, the hook portion 521 is disposed on one side of the insulator 51 located at the opening 123 and is partially suspended, forming an insulating gap 6 with the mounting groove 121 and forming an insulating connection with the mounting groove 121 through the insulator 51 .

[0054] In order to further reduce the axial dimension of the stator core, a positioning step 523 is formed between the protruding portion 5221 of the wire hanging portion 522 and the insulator 51, a second flange portion 32 is circumferentially provided on the upper insulating frame 3, and a third flange portion 41 is circumferentially provided on the lower insulating frame 4. The vertical length of the insulator 51 is smaller than the vertical length of the mounting groove 121, the second flange portion 32 abuts against one end of the insulator 51 away from the positioning step 523, and the third flange portion 41 is partially inserted into the mounting groove 121 and abuts against the positioning step 523, which is beneficial to reducing the axial dimension of the stator core.

[0055] In order to further make the installation of the stator core more reliable, a stop rib 122 is provided at the slot of the installation groove 121 located in the radial direction of the core body 1. The stop rib 122 cooperates with the insulator 51 to limit the position, thereby limiting the hook wire frame 5 in the radial direction of the core body 1, further improving the installation reliability of the hook wire frame 5.

[0056] Embodiment 2:

[0057] like Figures 9 to 11 As shown, in this embodiment, an angle is set between the vertical center line of the conductive terminal 52 and the vertical center line of the insulator 51, so that the force direction of the conductive terminal 52 tends to be consistent with the force direction of the stator coil 2, which is beneficial to reducing the stress concentration area at the bottom of the conductive terminal 52, thereby helping to ensure the service life of the wire hook frame 5.

[0058] It should be noted that the included angle may be any suitable angle such as 10°, 20°, 30°, etc.

[0059] For other contents not described in this embodiment, please refer to Embodiment 1.

[0060] Embodiment three:

[0061] like Figures 12 to 15 As shown, in this embodiment, the wire hooking frame 5 includes a first wire hooking frame 53 composed of an insulator 51 and a conductive terminal 52 and a second wire hooking frame 54 composed of an insulator 51 and at least two conductive terminals 52. The first wire hooking frame 53 and the second wire hooking frame 54 are respectively located in separate installation grooves 121, which is beneficial for connecting a plurality of stator coils 2 to one wire hooking frame 5, reducing the number of wire hooking frames 5, reducing the workload of installing and disassembling the wire hooking frames 5, and making assembly more convenient.

[0062] The second wire hooking frame 54 may be composed of one insulator 51 and two conductive terminals 52 , or may be composed of one insulator 51 and three conductive terminals 52 .

[0063] It should be noted that the mounting groove 121 of the core body 1 can be a first mounting groove for mounting the first wire hooking frame 53 and a second mounting groove for mounting the second wire hooking frame 53. The first mounting groove can be arranged on the left side of the second mounting groove, or on the right side of the second mounting groove.
