[0037] The terminal 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 3As shown, the terminal 1 according to an embodiment of the present invention includes a mounting part 11 and a hook part 12. The terminal 1 is used for a motor 100, which can be a plastic-encapsulated brushless DC motor. The motor 100 includes a stator assembly 10 and a PCB (Printed Circuit Board) board 20. The stator assembly 10 includes a stator component 2, which includes a housing 21 and a winding 22, with the winding 22 disposed inside the housing 21.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the mounting part 11 is fixed to the stator assembly 10 and connected to the winding 22 inside the stator assembly 10. The hook part 12 is connected to the mounting part 11 and is used to engage with the card hole 201 on the PCB board 20.

[0040] The stator assembly 10 generates a rotating magnetic field, providing the necessary magnetic field environment for the operation of the motor 100; the PCB board 20 provides electrical connections for electronic components and is widely used in various electronic devices. The terminals 1 are mostly made of conductive metals, which can realize the electrical connection between the winding 22 and the PCB board 20.

[0041] like Figure 1 and Figure 3 As shown, the hook part 12 is used to engage with the card hole 201 on the PCB board 20, which can better position the PCB board 20, so that the PCB board 20 can be installed in place, avoiding problems such as poor soldering when the PCB board 20 is soldered to the terminal 1. The PCB board 20 can be effectively fixed on the stator assembly 10, and the soldering of the PCB board 20 is relatively firm.

[0042] According to the embodiment of the present invention, the terminal 1 is fixed to the stator assembly 10 and connected to the winding 22 inside the stator assembly 10. The hook part 12 is connected to the mounting part 11 and engages with the locking hole 201 on the PCB board 20. This allows the PCB board 20 to be better positioned, so that the PCB board 20 can be installed in place. This avoids problems such as poor soldering when the PCB board 20 is soldered to the terminal 1. The PCB board 20 can be effectively fixed to the stator assembly 10, and the soldering of the PCB board 20 is more secure.

[0043] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the hook portion 12 includes two hooks 121, and the two hooks 121 are along the width direction of the hook portion 12 (e.g., Figure 1The three-way (as shown) are spaced apart and all engage with the locking holes 201. It can be understood that when the terminal 1 is assembled with the PCB board 20, along the width direction of the hook portion 12, the distance between the end faces of the two hooks 121 that are away from each other can be slightly greater than the distance between the locking holes 201 on the PCB board 20. The two hooks 121 can deform toward each other, so that the end faces of the two hooks 121 that are away from each other abut against the inner peripheral wall of the locking hole 201, increasing the reliability of the position of the PCB board 20.

[0044] Furthermore, such as Figure 1 and Figure 3 As shown, the latch 121 includes a connecting portion 1211 and a latching portion 1212. One end of the connecting portion 1211 is connected to the mounting portion 11 and passes through the latching hole 201. The latching portion 1212 is connected to the end of the connecting portion 1211 away from the mounting portion 11. The latching portion 1212 is located on the side of the PCB board 20 away from the mounting portion 11 and is adapted to abut against the PCB board 20. It can be understood that when the terminal 1 is assembled with the PCB board 20, after the latching portion 1212 passes through the latching hole 201 on the PCB board 20, the connecting portion 1211 engages with the latching hole 201. The latching portion 1212 can abut against the PCB board 20 on the side of the PCB board 20 away from the mounting portion 11, preventing the PCB board 20 from disengaging from the terminal 1 on the side away from the mounting portion 11, and further increasing the reliability of the position of the PCB board 20.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, guide slopes 12121 are provided on the side of the two latching parts 1212 that are away from each other. Along the direction from the latching part 1212 to the mounting part 11, the two guide slopes 12121 extend in a direction away from each other. That is, when the terminal 1 is assembled with the PCB board 20, under the guidance of the guide slopes 12121, the two latching parts 1212 deform in a direction that moves closer to each other, so that the latching hole 201 can accommodate the latching part 1212. After the PCB board 20 is installed in place, the latching part 1212 returns to its natural state. The elastic deformation of the terminal 1 can be used to achieve the engagement between the terminal 1 and the PCB board 20, making the assembly of the terminal 1 and the PCB board 20 relatively simple and reliable.

[0046] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the hook portion 12 also includes a base 122, which is disposed between the hook 121 and the mounting portion 11. Along the width direction of the hook portion 12, both ends of the hook 121 are recessed into the ends of the base 122. The end face of the base 122 near the hook 121 can abut against the side of the PCB board 20 near the mounting portion 11, thereby limiting the PCB board 20 in the direction near the mounting portion 11 and preventing the PCB board 20 from shifting during subsequent assembly of the motor 100.

[0047] In some embodiments of this utility model, such as Figure 1 As shown, the mounting part 11 includes a mounting body 111 and a receiving part 112, with the hook part 12 connected to one end of the mounting body 111; the receiving part 112 is located in the thickness direction of the mounting body 111 (e.g., ...). Figure 1 One side and one end of the winding 22 (shown in the second direction) are connected to the mounting body 111, and the winding 22 is connected to the receiving part 112. It is understood that, as... Figure 1 As shown, the receiving part 112 is perpendicular to the mounting part 11. The receiving part 112 can abut against the upper end face of the housing 21 of the stator assembly 2, increasing the reliability of the position of the terminal 1. The winding 22 is connected to the receiving part 112, and the hook 121 engages with the through hole on the PCB board 20, which can realize the electrical connection between the winding 22 and the PCB board 20, increasing the reliability of the electrical connection of the motor 100.

[0048] Furthermore, such as Figure 1 As shown, the receiving part 112 includes a bearing part 1121 and a crimping part 1122. Along the thickness direction of the mounting body 111, one end of the bearing part 1121 is connected to the mounting body 111, and the other end extends in a direction away from the mounting body 111. One end of the crimping part 1122 is connected to the bearing part 1121 and forms an angle with the bearing part 1121. The winding 22 can be passed between the bearing part 1121 and the crimping part 1122. Understandably, the enameled wire of the winding 22 can be threaded between the bearing portion 1121 and the crimping portion 1122. The crimping portion 1122 can be pressed and deformed to limit the winding 22 between the bearing portion 1121 and the crimping portion 1122, thereby improving the fixing strength of the winding 22. The crimping portion 1122 can also be pried open when disassembling the winding 22, making it easier to remove the winding 22 from between the bearing portion 1121 and the crimping portion 1122, thus making the installation and disassembly of the winding 22 more convenient.

[0049] Simultaneously, this design also facilitates heat dissipation and fixation of the winding 22, improving its performance and lifespan. The winding 22 can be effectively fixed and pressed within the receiving part 112, enhancing the electromagnetic performance of the entire stator assembly 2, thereby improving the operating efficiency and performance of the motor 100. Furthermore, by providing the carrying part 1121 and the pressing part 1122, different specifications and types of windings 22 can be accommodated, improving the versatility and flexibility of the receiving part 112. This allows for the selection and combination of appropriate windings 22 and receiving parts 112 according to actual needs during production and maintenance, reducing production costs and maintenance difficulty.

[0050] Furthermore, such as Figure 1 As shown, the support portion 1121 includes a first support plate 11211 and a second support plate 11212. Along the thickness direction of the mounting body 111, the length direction of the first support plate 11211 (e.g.) Figure 1 One end of the second direction shown is connected to the mounting body 111, and the other end extends in a direction away from the mounting body 111; along the width direction of the first bearing plate 11211 (e.g. Figure 1 The third direction shown), the length direction of the second bearing plate 11212 (as shown in the third direction), Figure 1 One end of the second carrier plate 11212 (as shown in the third direction) is connected to the first carrier plate 11211, and the other end extends away from the hook portion 12. The crimping portion 1122 is located at the end of the second carrier plate 11212 away from the first carrier plate 11211 and at the end of the second carrier plate 11212 near the mounting body 111 in the width direction, so that the carrier portion 1121 extends away from the hook portion 12. The winding 22 is located between the second carrier plate 11212 and the crimping portion 1122, avoiding the winding 22 from being too close to the hook 121 and the PCB board 20, reducing the possibility of electromagnetic interference and avoiding signal distortion or failure caused by electromagnetic interference. The coil generates heat when working. Maintaining a certain distance between the coil and the PCB board 20 can reduce heat conduction, thereby reducing the temperature of the PCB board 20 and improving its stability and reliability. Along the length direction of the hook portion 12 (e.g. Figure 1 As shown in the first direction, the crimping part 1122 is inclined in a direction away from the mounting body 111. During the assembly process of the motor 100, the crimping part 1122 can be pressed down more conveniently to limit the winding 22.

[0051] In some embodiments of this utility model, such as Figure 1 As shown, along the width direction of the crimping portion 1122, a snap-fit ​​groove 11221 is provided on the side of the crimping portion 1122 away from the snap-fit ​​portion 12. When assembling the winding 22, the end of the winding 22 can be snapped into the snap-fit ​​groove 11221 before assembling the coil, thus preventing the end from being wound into the winding 22 during assembly and avoiding affecting the assembly of the winding 22.

[0052] In some embodiments of this utility model, such as Figure 1 As shown, the mounting part 11 and the hook part 12 are a single piece. In this embodiment, the mounting part 11 and the hook part 12 are a single sheet metal structure, which can improve the structural strength and stability of the terminal 1 and ensure the stable conduction of current within the motor 100. At the same time, the use of a single sheet metal structure for the terminal 1 can also reduce the production cost of the terminal 1 and improve the assembly efficiency of the terminal 1.

[0053] Terminal 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings. It is to be understood that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0054] Specifically, terminal 1 includes mounting part 11 and hook part 12. Terminal 1 is used for motor 100. Motor 100 can be plastic-encapsulated brushless DC motor 100. Motor 100 includes stator assembly 10 and PCB board 20. Stator assembly 10 includes stator component 2. Stator component 2 includes housing 21 and winding 22. Winding 22 is disposed in housing 21.

[0055] The mounting part 11 is fixed to the stator assembly 10 and connected to the winding 22 inside the stator assembly 10. The hook part 12 is connected to the mounting part 11 and is used to engage with the hook hole 201 on the PCB board 20.

[0056] The mounting part 11 includes a mounting body 111 and a receiving part 112. A hook part 12 is connected to one end of the mounting body 111. The receiving part 112 is located on one side of the mounting body 111 in the thickness direction, and one end is connected to the mounting body 111. The winding 22 is connected to the receiving part 112. It is understood that the receiving part 112 is perpendicular to the mounting part 11, and the receiving part 112 can abut against the upper end face of the stator assembly 2's housing 21, increasing the reliability of the terminal 1's position. The winding 22 is connected to the receiving part 112, and the hook 121 engages with a through hole on the PCB board 20, enabling electrical connection between the winding 22 and the PCB board 20, increasing the reliability of the motor 100's electrical connection.

[0057] The receiving part 112 includes a bearing part 1121 and a crimping part 1122. Along the thickness direction of the mounting body 111, one end of the bearing part 1121 is connected to the mounting body 111, and the other end extends in a direction away from the mounting body 111. One end of the crimping part 1122 is connected to the bearing part 1121 and forms an angle with the bearing part 1121. The winding 22 can be passed between the bearing part 1121 and the crimping part 1122. Understandably, the enameled wire of the winding 22 can be threaded between the bearing portion 1121 and the crimping portion 1122. The crimping portion 1122 can be pressed and deformed to limit the winding 22 between the bearing portion 1121 and the crimping portion 1122, thereby improving the fixing strength of the winding 22. The crimping portion 1122 can also be pried open when disassembling the winding 22, making it easier to remove the winding 22 from between the bearing portion 1121 and the crimping portion 1122, thus making the installation and disassembly of the winding 22 more convenient.

[0058] The support portion 1121 includes a first support plate 11211 and a second support plate 11212. Along the thickness direction of the mounting body 111, one end of the first support plate 11211 is connected to the mounting body 111 along its length direction, and the other end extends in a direction away from the mounting body 111. Along the width direction of the first support plate 11211, one end of the second support plate 11212 is connected to the first support plate 11211 along its length direction, and the other end extends in a direction away from the hook portion 12. The pressing portion 1122 is located at the end of the second support plate 11212 away from the first support plate 11211 and at the end of the second support plate 11212 near the mounting body 111 along its width direction. Along the length direction of the hook portion 12, the pressing portion 1122 is inclined in a direction away from the mounting body 111. During the assembly process of the motor 100, the pressing portion 1122 can be pressed down relatively easily to limit the winding 22. Along the width direction of the crimping portion 1122, a snap-fit ​​groove 11221 is provided on the side of the crimping portion 1122 away from the snap-fit ​​portion 12. When assembling the winding 22, the end of the winding 22 can be snapped into the snap-fit ​​groove 11221 before assembling the coil, thus preventing the end from being wound into the winding 22 during assembly and avoiding affecting the assembly of the winding 22.

[0059] The latching part 12 is used to engage with the latching hole 201 on the PCB board 20, which can better position the PCB board 20, allowing the PCB board 20 to be installed in place and avoiding problems such as poor soldering when the PCB board 20 is soldered to the terminal 1. The PCB board 20 can be effectively fixed on the stator assembly 10, and the soldering of the PCB board 20 is relatively firm. The latching part 12 includes two latches 121, which are spaced apart along the width direction of the latching part 12 and both engage with the latching hole 201. The latches 121 include a connecting part 1211 and a latching part 1212. One end of the connecting part 1211 is connected to the mounting part 11 and passes through the latching hole 201. The latching part 1212 is connected to the end of the connecting part 1211 away from the mounting part 11. The latching part 1212 is located on the side of the PCB board 20 away from the mounting part 11 and is adapted to abut against the PCB board 20.

[0060] It is understandable that when terminal 1 is assembled with PCB board 20, the distance between the opposite ends of the two hooks 121 along the width direction of the hook portion 12 can be slightly greater than the distance between the locking holes 201 on PCB board 20. The two hooks 121 can deform towards each other, so that the opposite ends of the two hooks 121 abut against the inner peripheral wall of the locking hole 201, increasing the positional reliability of PCB board 20. When terminal 1 is assembled with PCB board 20, after the locking portion 1212 passes through the locking hole 201 on PCB board 20, the connecting portion 1211 engages with the locking hole 201. The locking portion 1212 can abut against PCB board 20 on the side of PCB board 20 away from mounting portion 11, preventing PCB board 20 from disengaging from terminal 1 on the side away from mounting portion 11, further increasing the positional reliability of PCB board 20.

[0061] The two latching portions 1212 have guide slopes 12121 on their opposite sides. Along the direction from the latching portion 1212 to the mounting portion 11, the two guide slopes 12121 extend in a direction away from each other. That is, when the terminal 1 is assembled with the PCB board 20, guided by the guide slopes 12121, the two latching portions 1212 deform in a direction closer to each other, allowing the latching hole 201 to accommodate the latching portion 1212. After the PCB board 20 is installed in place, the latching portion 1212 returns to its natural state. The elastic deformation of the terminal 1 allows for the engagement between the terminal 1 and the PCB board 20, making the assembly of the terminal 1 and the PCB board 20 relatively simple and reliable. The latching hook portion 12 also includes a base 122, which is located between the latching hook 121 and the mounting portion 11. Along the width direction of the latching hook portion 12, the two ends of the latching hook 121 are recessed into the two ends of the base 122. The end face of the base 122 near the hook 121 can abut against the side of the PCB board 20 near the mounting part 11, which can limit the PCB board 20 in the direction near the mounting part 11 and prevent the PCB board 20 from shifting during the subsequent assembly of the motor 100.

[0062] The mounting part 11 and the hook part 12 are integrated as a single unit. In this embodiment, the mounting part 11 and the hook part 12 are integrated sheet metal structures, which can improve the structural strength and stability of the terminal 1 and ensure the stable conduction of current within the motor 100.
