[0062] The first winding portion 10 is columnar in shape, for example, the first winding portion 10 is a cylindrical member extending in the up-down direction. The first winding portion 10 can be configured to wind a winding wire, that is, the winding wire can be wound on the first winding portion 10. ​

[0063] The first claviform part 20 is arranged at one end of the axial direction of the first winding part 10, and the second claviform part 30 is arranged at the other end of the axial direction of the first winding part 10, for example, the first claviform part 20 is arranged at the upper end of the first winding part 10, and the second claviform part 30 is arranged at the lower end of the first winding part 10. The mounting part 40 is arranged at the outer periphery of the first claviform part 20, for example, the mounting part 40 is arranged at the outer periphery position of about one fourth of the first claviform part 20. At least one first through hole 41 is arranged on the mounting part 40, that is, the first through hole 41 is arranged to pass through, which can be used for mounting the pin 200, that is, the pin 200 can be mounted in the first through hole 41, and the winding wire can be connected to the pin 200 and the like during mounting.

[0064] That is, the long side of the mounting part 40 extends along the length direction of itself, the thick side extends along the thickness direction of itself, and the high side extends along the height direction of itself. The length direction is perpendicular to the axial direction of the first winding part 10, the thickness direction is parallel to one radial direction of the first winding part 10, and the height direction is parallel to the axial direction of the first winding part 10, for example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction. The axis of the first winding part 10 is shown by the dashed line in the figure. Figure 3

[0065] The outer surface of the mounting part 40 mainly includes the first surface 42, the second surface 43 and the third surface 44, the first surface 42 and the third surface 44 are distributed apart in the height direction, that is, they are distributed apart in parallel to the axial direction of the first winding part 10 and connected through the second surface 43, that is, the first surface 42 and the third surface 44 are connected in an indirect connection manner, the second surface 43 is connected with the first surface 42 and the third surface 44 respectively, and the second surface 43 is located at one side of the mounting part 40 in the thickness direction. Moreover, a part of the first through hole 41 is arranged on the first surface 42, and another part is arranged on the third surface 44, that is, one end of the first through hole 41 communicates with the first surface 42, and the other end of the first through hole 41 communicates with the third surface 44.

[0066] ​The mounting portion 40 is provided with a plurality of first through holes 41, that is, the number of first through holes 41 is multiple, and the plurality of first through holes 41 are distributed along the length direction, for example, distributed along the left-right direction, which facilitates the simultaneous installation of a plurality of pins 200 and facilitates the simultaneous bending of the plurality of pins 200 and the like. Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by distributing the plurality of first through holes 41 along the length direction, it is beneficial to control the orderly arrangement of the plurality of pins 200 on the mounting portion 40, which is beneficial to the subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when the number of pins 200 is multiple, the mounting portion 40 can adopt a plastic structure, or the inner wall of the first through hole 41 is coated with an insulating material to achieve insulation between adjacent two pins 200 and prevent short circuit.

[0067] At least a portion of the first cover plate 60 is located on the side of the mounting portion 40 away from the axis of the first winding portion 10, that is, the first cover plate 60 can cover the outer side of the mounting portion 40, for example, on the projection plane extending in the height direction along the up-down direction and the width direction along the horizontal direction, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It can be understood that in the present embodiment, the side close to the axis direction of the first winding portion 10 is the inner side, and the side away from the axis direction of the first winding portion 10 is the outer side. The first cover plate 60 is provided with a second through hole 61, and one end of the pin 200 is connected with the lead 400 after passing through the second through hole 61, that is, a part of the pin 200 extends out of the first through hole 41 and then extends into the second through hole 61, and then passes through the second through hole 61 and is connected with the lead 400. In the present embodiment, by adopting the first cover plate 60, the mounting portion 40 can be shielded, and the pin 200 and the winding wire extending out of the mounting portion 40 can also be shielded, which can improve the appearance and safety, and also can limit the pin 200 through the second through hole 61. In addition, by providing the second through hole 61 on the first cover plate 60, one end of the pin 200 is connected with the lead 400 after passing through the second through hole 61, for example, one end of the pin 200 is welded with the lead 400 after passing through the second through hole 61, and under the shielding of the first cover plate 60, the metal material during welding is not easy to splash into the inside of the gear assembly 500.

[0068] In addition, the first cover plate 60 in the embodiment of the present application mainly consists of a first connecting body 65, a second connecting body 66 and a third connecting body 67. The second connecting body 66 is connected with the first connecting body 65, and a first avoiding space 68 is formed between the second connecting body 66 and the first connecting body 65. The mounting portion 40 can be avoided through the first avoiding space 68, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoiding space 68. In the inner-outer direction, at least a part of the second connecting body 66 and the first connecting body 65 are staggered to form a space for the pin 200 to extend outward. Here, the inward direction is the axial direction of the first winding portion 10, and the outward direction is the side where the second cover plate 70 is located.

[0069] The second connecting body 66 is provided with a second through hole 61, and one end of the pin 200 is connected with the lead 400 after penetrating through the second through hole 61. The third connecting body 67 is provided with a plurality of first grooves 63, for example, each first groove 63 extends along the axial direction parallel to the first winding portion 10. At least a part of the lead 400 can be installed in the first groove 63, so that the limiting effect on the lead 400 can be achieved.

[0070] The second cover plate 70 is arranged on the side of the first cover plate 60 away from the axial direction of the first winding portion 10, that is, the second cover plate 70 is arranged on the side of the first cover plate 60 away from the mounting portion 40. In other words, the second cover plate 70 is arranged on the outside of the first cover plate 60, for example, on the projection plane extending in the height direction along the upward-downward direction and the width direction along the horizontal direction, the orthographic projection of the second cover plate 70 covers the orthographic projection of the first cover plate 60. In the embodiment, the second cover plate 70 can shield the lead 400 and the connection position of the lead 400 and the pin 200, and can improve the aesthetic appearance, structural stability and safety, and avoid the connection position of the lead 400 and the pin 200 and the lead 400 from being affected by the external environment.

[0071] In addition, in the length direction, the two sides of the second connecting body 66 and the third connecting body 67 are respectively clamped with the second cover plate 70. For example, the left side of the second connecting body 66 is clamped with the left side of the second cover plate 70, and the right side of the second connecting body 66 is also clamped with the right side of the second cover plate 70. Similarly, the left side of the third connecting body 67 is clamped with the left side of the second cover plate 70, and the right side of the third connecting body 67 is also clamped with the right side of the second cover plate 70. The clamping of the four positions can be achieved. Alternatively, the clamping structures of the two sides of the second connecting body 66 are corresponding, the clamping structures of the two sides of the third connecting body 67 are symmetrical, and the four clamping positions form a rectangle, which can improve the combination stability, expand the range of the combination area, and facilitate processing and manufacturing by adopting the symmetrical design.

[0072] It can be understood that, by adopting the second connecting body 66, the second connecting body 66 can not only avoid the pin 200 in the inner-outer direction, provide space for the extension of the pin 200, but also provide a connecting position and a connecting structure for the convenient connection between the first cover plate 60 and the second cover plate 70. Similarly, the third connecting body 67 not only plays a limiting role on the lead 400, but also plays a function of providing a connecting position and a connecting structure for the convenient connection between the first cover plate 60 and the second cover plate 70.

[0073] According to one embodiment of the present application, as shown in Figure 1 the length direction, the second connecting body 66 and the third connecting body 67 are respectively provided with a clamping protrusion 64 on both sides, and the second cover plate 70 is provided with a clamping groove 71 corresponding to the clamping protrusion 64. For example, the length direction is the left-right direction, the second connecting body 66 is respectively provided with a clamping protrusion 64 on the left side and the right side, and the second cover plate 70 is also respectively provided with a clamping groove 71 on the left side and the right side. The clamping protrusion 64 and the clamping groove 71 can be detachably connected to realize the installation and disassembly between the second cover plate 70 and the first cover plate 60. In this embodiment, by adopting the cooperation of the clamping protrusion 64 and the clamping groove 71, it is convenient to operate, and the installation and disassembly are convenient.

[0074] In some specific embodiments of the present application, in the length direction, the second connecting body 66 and the third connecting body 67 are respectively provided with a clamping groove 71 on both sides, and the second cover plate 70 is provided with a clamping protrusion 64 corresponding to the clamping groove 71. For example, the second connecting body 66 is respectively provided with a clamping groove 71 on the left side and the right side, and the second cover plate 70 is provided with a clamping protrusion 64 on the left side and the right side, which is convenient for installation and disassembly.

[0075] According to one embodiment of the present application, in the length direction, one of the second connecting body 66 and the third connecting body 67 is respectively provided with a clamping groove 71 on both sides, and the other is respectively provided with a clamping protrusion 64, and the second cover plate 70 is provided with a clamping protrusion 64 corresponding to the clamping groove 71 and a clamping groove 71 corresponding to the clamping protrusion 64. For example, the second connecting body 66 is respectively provided with a clamping groove 71 on the left side and the right side, and the third connecting body 67 is provided with a clamping protrusion 64 on the left side and the right side; for another example, the second connecting body 66 is provided with a clamping protrusion 64 on the left side and the right side, and the third connecting body 67 is provided with a clamping groove 71 on the left side and the right side, which is convenient for operation.

[0076] It can be seen from the above combination that the clamping mode between the second cover plate 70 and the first cover plate 60 is various.

[0077] In some embodiments of the present application, the number of the clamping protrusions 64 and the clamping grooves 71 is multiple and one-to-one correspondence, and in the height direction, the multiple clamping protrusions 64 are distributed at intervals. For example, there are a total of four clamping protrusions 64, two clamping protrusions 64 are close to the upper side and form a group, and two clamping protrusions 64 are close to the lower side and form a group. In this embodiment, by limiting the multiple clamping protrusions 64 to be distributed at intervals, the limiting of different positions can be realized, and the structural stability can be improved.

[0078] According to one embodiment of the present application, in the radial direction of the first winding part 10, the cross-sectional shape of the clamping protrusion 64 is triangular, as shown in Figure 8 and Figure 10 The outer side surface of the clamping protrusion 64 includes a first side surface, a second side surface 641 and a third side surface 642, the first side surface is connected with the side surface of the second connecting body 66 or the third connecting body 67, the second side surface 641 is spaced apart from the first connecting body 65, the third side surface 642 is connected with the first side surface and the second side surface 641 respectively, and the included angle between the third side surface 642 and the second side surface 641 is an acute angle. In this embodiment, by limiting the shape of the clamping protrusion 64, the second cover plate 70 can be slidably installed along the axial direction parallel to the first winding part 10. In addition, the clamping protrusion 64 with the above-mentioned shape can realize the limiting of the second cover plate 70 in the circumferential direction.

[0079] In some embodiments of the present application, in the height direction, the second connecting body 66 and the third connecting body 67 are distributed at intervals, for example, the second connecting body 66 is located above the third connecting body 67 and is spaced apart. In this embodiment, the space formed by the spacing can avoid the connection position of the lead 400 and the pin 200, and facilitate the mutual connection and connection operation of the lead 400 and the pin 200.

[0080] In the height direction, the multiple first through holes 41 and the multiple first grooves 63 are one-to-one correspondence, for example, at least a part of the first through hole 41 is located above one first groove 63, after one pin 200 is inserted into the first through hole 41, the lower end is stretched out of the first through hole 41, and at least a part of the lead 400 can be installed in the first groove 63, one lead 400 corresponds to one pin 200 and is connected. In this embodiment, by adopting the one-to-one correspondence of the multiple first through holes 41 and the multiple first grooves 63, the structural order can be improved.

[0081] It should be noted that the above-mentioned conditions can be satisfied separately, that is, the second connecting body 66 and the third connecting body 67 are distributed at intervals in the height direction, or the multiple first through holes 41 and the multiple first grooves 63 are one-to-one correspondence in the height direction, or the above-mentioned conditions can be satisfied simultaneously, and the specific design can be carried out according to the product demand, and the flexibility is strong.

[0082] According to one embodiment of this application, the coil frame 100 further includes a blocking portion 50, which protrudes from the surface of the mounting portion 40 away from the second blade-shaped portion 30 and is located on the side of the first through hole 41 in the direction close to the axis of the first winding portion 10. The blocking portion 50 is capable of preventing metal beads generated during the metal processing of the pin 200 from rolling toward the axis of the first winding portion 10. The blocking portion 50 is detachably connected to the first cover plate 60.

[0083] The blocking portion 50 protrudes from the surface of the mounting portion 40 on the side away from the second blade-shaped portion 30, and the blocking portion 50 is located on the side of the first through hole 41 near the axis of the first winding portion 10. For example, the first blade-shaped portion 20 is located above the second blade-shaped portion 30, and the blocking portion 50 is located on the upper surface of the mounting portion 40. Moreover, as... Figure 2 As shown, at least a portion of the gear assembly 500 is located on one side of the blocking portion 50. For example, the gear assembly 500 includes multiple meshing gears, with at least a portion of the gears located on one side of the blocking portion 50. The pin 200 is located on the other side of the blocking portion 50. The blocking portion 50 prevents metal beads generated during the metal processing of the pin 200 from rolling into the gear assembly 500. For example, during tinning of the pin 200, it prevents solder beads from entering the gear assembly 500, causing jamming or even seizing. In other words, it avoids the solder beads generated during tinning of existing motor terminals from splashing into the gearbox. Furthermore, during assembly, tinning can be performed after winding enameled wire around the pin 200, providing a protective function. Winding an enameled wire connector around the pin 200 and tinning allows the pin 200 and the enameled wire to conduct to each other. Additionally, the detachable connection methods here include, but are not limited to, snap-fit, threaded connection, and bolted connection.

[0084] In some specific embodiments of the invention in this application, the blocking part 50 includes: a body 51, a first extension 52, and a second extension 53.

[0085] Specifically, the body 51 is located on the side of the first cover plate 60 near the axis of the first winding portion 10, and can prevent metal beads generated during the metal processing of the pin 200 from rolling toward the axis of the first winding portion 10. For example, the axis of the first winding portion 10 is provided on the inner side of the body 51, and the first through hole 41 is provided on the outer side of the body 51. After the pin 200 is installed, the body 51 is located between the axis of the first winding portion 10 and at least a portion of the pin 200. During the metal processing of the pin 200, such as during tinning, the solder beads are blocked by the body 51 and will not move toward the gear assembly 500 near the axis of the first winding portion 10.

[0086] In the length direction, one end of the first extension 52 is connected to the end of the main body 51, and the other end of the first extension 52 is connected to the second extension 53. For example, in the left-right direction, the direction closer to the axis of the first winding portion 10 is the rear end, and the direction farther from the axis of the first winding portion 10 is the front end. The front end of the first extension 52 is connected to the right end of the main body 51, and the rear end of the first extension 52 is connected to the left end of the second extension 53. For another example, the front end of the first extension 52 is connected to the left end of the main body 51, and the rear end of the first extension 52 is connected to the right end of the second extension 53. In this embodiment, as... Figure 4 As shown, the second extension 53, the first extension 52, and the first winding portion 10 can cooperate to form a "U"-shaped component with the opening facing the axial direction of the first winding portion 10. The first connecting body 65 has a second clearance space 62, and the second extension 53 is located in the second clearance space 62, which can improve the tightness of the connection, improve the protective effect, and also improve the structural compactness. The second extension 53 is detachably connected to the first cover plate 60. The detachable connection method here includes, but is not limited to, snap-fit, threaded connection, bolt connection, etc. In this embodiment, by using the second extension 53, the second cover plate 70 can be limited in the direction parallel to the axial direction of the first winding portion 10.

[0087] According to one embodiment of this application, the first flange-like portion 20 overlaps with the first connector 65 in a direction parallel to the axis of the first winding portion 10. For example, if the axis of the first winding portion 10 is vertical, the lower end of the first connector 65 contacts the first flange-like portion 20. In this embodiment, it not only provides a sealing effect but also supports the first connector 65.

[0091] In other words, the motor according to the embodiment of the application adopts the combination of the coil assembly, the gear assembly 500, the first cover plate 60, and the second cover plate 70, the coil assembly mainly includes the pin 200 and the motor skeleton, and the motor skeleton mainly includes the first winding portion 10, the first gong-shaped portion 20, the second gong-shaped portion 30, the mounting portion 40, and the blocking portion 50.

[0092] The first winding portion 10 is columnar in shape, for example, the first winding portion 10 is a cylindrical member extending in the up-down direction. The first winding portion 10 can be used for winding the winding wire, that is, the winding wire can be wound on the first winding portion 10.

[0093] The first flange 20 is arranged at one end of the first winding portion 10 in the axial direction, and the second flange 30 is arranged at the other end of the first winding portion 10 in the axial direction. For example, the first flange 20 is arranged at the upper end of the first winding portion 10, and the second flange 30 is arranged at the lower end of the first winding portion 10. The mounting portion 40 is arranged at the outer periphery of the first flange 20. For example, the mounting portion 40 is arranged at the outer periphery of about one fourth of the first flange 20. The first through hole 41 is arranged on the mounting portion 40. The first through hole 41 is arranged to pass through the mounting portion 40, and can be used to mount the pin 200. That is, the pin 200 can be mounted in the first through hole 41, and the winding wire can be connected to the pin 200 during mounting. In this embodiment, the shape of the cross section of the pin 200 is not limited. For example, the cross section of the pin 200 is square, which can prevent the winding wire from sliding.

[0094] In addition, the blocking portion 50 protrudes from the surface of the mounting portion 40 on the side away from the second flange 30, and the blocking portion 50 is located on the side of the first through hole 41 close to the axis of the first winding portion 10. For example, the first flange 20 is located above the second flange 30, and the blocking portion 50 is located on the upper surface of the mounting portion 40.

[0095] In addition, at least a part of the gear assembly 500 is located on the side of the blocking portion 50. For example, the gear assembly 500 includes a plurality of gears that mesh with each other, and at least a part of the gears is located on the side of the blocking portion 50. The pin 200 is located on the other side of the blocking portion 50, and the metal beads generated during the metal processing of the pin 200 can be blocked by the blocking portion 50 from rolling to the gear assembly 500. For example, when the pin 200 is tinned, the tin beads after tinning can be prevented from entering the interior of the gear assembly 500, causing jamming or even locking.

[0096] In addition, at least a portion of the first cover plate 60 is arranged on the side of the mounting portion 40 away from the axis of the first winding portion 10, that is, the first cover plate 60 can cover the outer side of the mounting portion 40, for example, on a projection plane extending in the height direction along the upward and downward directions and in the width direction along the horizontal direction, the orthographic projection of the first cover plate 60 covers the orthographic projection of the mounting portion 40. It can be understood that in the present embodiment, the side close to the axis direction of the first winding portion 10 is the inner side, and the side away from the axis direction of the first winding portion 10 is the outer side. The second through hole 61 is arranged on the first cover plate 60, and one end of the pin 200 passes through the second through hole 61 and is connected with the lead wire 400, that is, a portion of the pin 200 extends out of the first through hole 41 and then extends into the second through hole 61, and then passes through the second through hole 61 and is connected with the lead wire 400. In the present embodiment, by adopting the first cover plate 60, the mounting portion 40 can be shielded, and the pin 200 and the winding wire extending out of the mounting portion 40 can also be shielded, which can improve the appearance and safety, and the pin 200 can also be limited by the second through hole 61. In addition, by arranging the second through hole 61 on the first cover plate 60, one end of the pin 200 passes through the second through hole 61 and is connected with the lead wire 400, for example, one end of the pin 200 is welded with the lead wire 400 after passing through the second through hole 61, and under the shielding of the first cover plate 60, the metal material during welding is not easy to splash into the inside of the gear assembly 500.

[0097] The second cover plate 70 is arranged on the side of the first cover plate 60 away from the mounting portion 40, that is, the second cover plate 70 is arranged on the outer side of the first cover plate 60, for example, on a projection plane extending in the height direction along the upward and downward directions and in the width direction along the horizontal direction, the orthographic projection of the second cover plate 70 covers the orthographic projection of the first cover plate 60. In the present embodiment, by arranging the second cover plate 70, the lead wire 400 and the connection position of the lead wire 400 and the pin 200 can be shielded, which can improve the appearance, structural stability and safety, and avoid the connection position of the lead wire 400 and the pin 200 and the lead wire 400 from being affected by the external environment.

[0098] Therefore, according to the motor of the present application, the combination of the coil assembly, the gear assembly 500, the first cover plate 60 and the second cover plate 70 can not only block the metal beads generated during the metal processing of the pin 200 from rolling to the gear assembly 500 by the blocking portion 50, which can effectively prevent the gear assembly 500 from being affected by the metal beads, for example, causing the motor to jam, etc.; but also can improve the appearance, structural stability and safety by the first cover plate 60 and the second cover plate 70.

[0099] According to one embodiment of the present application, the highest end of the pin 200 is higher than the highest end of the blocking portion 50 in the direction parallel to the axis of the first winding portion 10.

In this embodiment, by limiting the position of the highest end of the pin 200, the upper part of the pin 200 mounted into the first through hole 41 can be forced to bend outwardly during the mounting process by passing through the blocking portion 50 in the direction from inside to outside, driving the upper part of the pin 200 to bend outwardly.

[0100] In some embodiments of the present application, as shown in Figure 3 the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49 in the direction from the mounting portion 40 to the axis of the first winding portion 10. That is, the first through hole 41, the gap 49 and the blocking portion 50 are arranged in sequence in the direction from outside to inside. In this embodiment, by providing the gap 49, the upper part of the pin 200 mounted into the first through hole 41 can be forced to bend outwardly during the mounting process by passing through the gap 49, for example, the pin 200 in the first through hole 41 extends substantially in the up-down direction, and the pin 200 above the first through hole 41 bends outwardly relative to the pin 200 in the first through hole 41 after being forced to bend outwardly.

[0101] It should be noted that the condition that the highest end of the pin 200 is higher than the highest end of the blocking portion 50 in the direction parallel to the axis of the first winding portion 10 can be satisfied alone, the condition that the blocking portion 50 is spaced apart from the first through hole 41 to form a gap 49 in the direction from the mounting portion 40 to the axis of the first winding portion 10 can be satisfied alone, or both conditions can be satisfied simultaneously. The bending mode can be various according to the product design requirements.

[0103] That is, the outer surface of the mounting portion 40 mainly comprises the first surface 42, the second surface 43 and the third surface 44, the first surface 42 and the third surface 44 are distributed at intervals, for example, in the direction parallel to the axis of the first winding portion 10 and are connected by the second surface 43, that is, the first surface 42 and the third surface 44 are connected in an indirect connection manner, and the second surface 43 is connected with the first surface 42 and the third surface 44 respectively. Moreover, a part of the first through hole 41 is arranged on the first surface 42, and another part is arranged on the third surface 44, that is, one end of the first through hole 41 communicates with the first surface 42, and the other end of the first through hole 41 communicates with the third surface 44.

[0104] In addition, the outer side of the mounting portion 40 is provided with an opening groove 48 which is spaced apart from the first through hole 41, and a part of the opening groove 48 is arranged on the first surface 42, another part is arranged on the second surface 43, and the third part is arranged on the third surface 44. That is, the opening groove 48 respectively communicates with the first surface 42, the second surface 43 and the third surface 44. In this embodiment, the winding wire on the first winding portion 10 can be connected with the part of the pin 200 which protrudes out of the first through hole 41 through the opening groove 48. For example, the upper part of the pin 200 protrudes out of the upper end of the first through hole 41 and is connected with the winding wire. In this embodiment, the position of the winding wire can be limited by arranging the opening groove 48, so as to avoid the interference between the winding wire and other structures, and improve the efficiency and safety of the winding wire.

[0105] In addition, the angle between the third surface 44 and the second surface 43 is obtuse, for example, the second surface 43 extends in the vertical direction, the third surface 44 is below the first surface 42, and the angle between the third surface 44 and the second surface 43 is obtuse, and the third surface 44 is arranged inclinedly relative to the second surface 43, so as to buffer the bending degree of the winding wire connected between the mounting portion 40 and the first winding portion 10, and avoid the winding wire being cut off due to the outer surface of the mounting portion 40.

[0106] According to one embodiment of the present application, the outer surface of the mounting portion 40 further comprises a fourth surface 47, the fourth surface 47 is parallel to the first surface 42, the third surface 44 is connected with the first anvil-shaped portion 20 through the fourth surface 47, and a part of the opening groove 48 is arranged on the fourth surface 47.

[0107] That is, in the embodiment, the outer surface of the mounting portion 40 mainly comprises the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47, the fourth surface 47 is connected with the third surface 44 and the first clapper-shaped portion 20 respectively, and the third surface 44 is indirectly connected with the first clapper-shaped portion 20.

[0108] In the embodiment, by adopting the fourth surface 47, the area of the region for machining the third surface 44 on the mounting portion 40 can be reduced, and the machining is facilitated. In addition, by connecting the opening slot 48 with the fourth surface 47, not only the machining of the opening slot 48 on the outer surface of the mounting portion 40 is facilitated, but also the wall edge friction of the winding wire caused by the opening slot 48 being too short can be avoided.

[0109] In some embodiments of the present application, in the direction parallel to the axis of the first winding portion 10, the width dimension of the end of the opening slot 48 away from the second clapper-shaped portion 30 is smaller than the width dimension of the end close to the second clapper-shaped portion 30. For example, the axis direction of the first winding portion 10 is the up-down direction, the second clapper-shaped portion 30 is located below the first clapper-shaped portion 20, and the width dimension of the upper end of the opening slot 48 is smaller than the width dimension of the lower end of the opening slot 48. The upper section of the opening slot 48 can be a straight slot section extending in the up-down direction, and the lower section of the opening slot 48 can be a horn-shaped slot section with a narrow upper part and a wide lower part extending in the up-down direction. In the embodiment, by limiting the shape of the opening slot 48, the protection effect on the winding wire can be improved, and the winding wire in the first winding portion 10 and the opening slot 48 is prevented from being disconnected due to the edge friction of the opening slot 48.

[0111] That is, the first cover plate 60 of the embodiment of the present application is mainly composed of the first connecting body 65, the second connecting body 66 and the third connecting body 67. The second connecting body 66 is connected with the first connecting body 65, and the first avoiding space 68 is formed by cooperation between the second connecting body 66 and the first connecting body 65. The mounting portion 40 can be avoided through the first avoiding space 68, that is, after the first cover plate 60 is installed, the mounting portion 40 can extend into the first avoiding space 68.

[0113] In some specific embodiments of the present application, in a direction perpendicular to the axis of the first winding portion 10, the two sides of the second connecting body 66 and the third connecting body 67 are respectively clamped with the second cover plate 70. For example, the left side of the second connecting body 66 is clamped with the left side of the second cover plate 70, and the right side of the second connecting body 66 is also clamped with the right side of the second cover plate 70. Similarly, the left side of the third connecting body 67 is clamped with the left side of the second cover plate 70, and the right side of the third connecting body 67 is also clamped with the right side of the second cover plate 70.

[0114] In the embodiment, by limiting that in a direction perpendicular to the axis of the first winding portion 10, the two sides of the second connecting body 66 and the third connecting body 67 are respectively clamped with the second cover plate 70, the combination firmness is improved. During assembly, by limiting the shape of the clamping structure, the second cover plate 70 can be covered on the outside of the first cover plate 60 along the direction parallel to the axis of the first winding portion 10, or the second cover plate 70 can be separated from the first cover plate 60 along the direction parallel to the axis of the first winding portion 10, which is convenient for use and operation. In addition, by adopting the clamping mode, the installation and disassembly are convenient. By clamping the two sides respectively, the overall stability can also be improved.

[0115] According to one embodiment of the present application, the inner wall surface of the second cover plate 70 opposite to the first cover plate 60 is provided with a plurality of second clamping portions 72 and a plurality of crimping protrusions 74.

[0116] Specifically, a second slot 73 is formed between two adjacent second clamping portions 72, or a second slot 73 is formed between the second clamping portion 72 and the edge of the second cover plate 70, the second slot 73 is used to install the connection part between the pin 200 and the lead 400, and the crimping protrusion 74 is used to abut the lead 400 after the second cover plate 70 is installed to the first cover plate 60.

[0117] That is, the second cover plate 70 is arranged outside at least a part of the first cover plate 60, and the inner side of the second cover plate 70 is provided with the second clamping portion 72 and the crimping protrusion 74. The number of the second clamping portion 72 is multiple, and a second slot 73 is formed between two adjacent second clamping portions 72. Or, a second slot 73 is formed between the second clamping portion 72 and the edge of the second cover plate 70, for example, a plurality of second clamping portions 72 are distributed in the left-right direction, the leftmost second clamping portion 72 has a second slot 73 with the left edge of the second cover plate 70, and the rightmost second clamping portion 72 has a second slot 73 with the right edge of the second cover plate 70. In this embodiment, by arranging the second slot 73, the connection part between the pin 200 and the lead 400 can be installed in the second slot 73, so that the connection part can be limited. In addition, after the second cover plate 70 is installed to the first cover plate 60, the crimping protrusion 74 can abut the lead 400 to limit the lead 400. By installing the second cover plate 70 to the first cover plate 60, an acting force can be applied to the lead 400, so that at least a part of the lead 400 is clamped between the crimping protrusion 74 and the first cover plate 60.

[0118] In some specific embodiments of the present application, the mounting portion 40 has a length direction, a thickness direction and a height direction, the length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to one radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10. The number of the first through hole 41 is multiple, and the multiple first through holes 41 are distributed in the length direction.

[0119] That is, the long side of the mounting portion 40 extends in the length direction of itself, the thick side extends in the thickness direction of itself, and the high side extends in the height direction of itself. The length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to one radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10, for example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

[0120] In addition, when the first through holes 41 are multiple, the multiple first through holes 41 can be distributed along the length direction, for example, distributed along the left-right direction, facilitating simultaneous installation of multiple pins 200 and facilitating simultaneous bending and other operations on the multiple pins 200. Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by distributing the multiple first through holes 41 along the length direction, it is beneficial to control the orderly arrangement of the multiple pins 200 on the mounting portion 40, and beneficial to subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when the number of pins 200 is multiple, the mounting portion 40 can adopt a plastic structure, or the inner wall of the first through hole 41 is coated with an insulating material to achieve insulation between adjacent two pins 200 and prevent short circuit.

That is, the blocking portion 50 is a solid flat plate structure, and the multiple first through holes 41 are distributed along the length direction. By adopting the blocking portion 50, the range of the blocking metal beads can be expanded, and the metal beads generated during the metal processing of the multiple pins 200 can be simultaneously blocked.

[0125] Specifically, the first winding portion 10 has a columnar shape, the first winding portion 10 is used for winding a winding wire, the first gong-shaped portion 20 is arranged at one end of the first winding portion 10 in the axial direction, the second gong-shaped portion 30 is arranged at the other end of the first winding portion 10 in the axial direction, the mounting portion 40 is arranged at the outer periphery of the first gong-shaped portion 20, the mounting portion 40 is provided with a first through hole 41, the first through hole 41 is used for mounting a pin 200, and the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the second gong-shaped portion 30 and is located on the side of the first through hole 41 close to the axial line of the first winding portion 10, and the blocking portion 50 can block the metal beads generated during the metal processing of the pin 200 from rolling toward the axial line of the first winding portion 10.

[0126] In other words, the coil former 100 according to the present application mainly comprises a first winding portion 10, a first gong-shaped portion 20, a second gong-shaped portion 30, a mounting portion 40, and a blocking portion 50.

[0127] The first winding portion 10 is in a columnar shape, for example, the first winding portion 10 is a cylindrical member extending in the up-down direction. The first winding portion 10 is used for winding the winding wire, that is, the winding wire can be wound on the first winding portion 10.

[0128] The first flange portion 20 is arranged at one end of the first winding portion 10 in the axial direction, and the second flange portion 30 is arranged at the other end of the first winding portion 10 in the axial direction, for example, the first flange portion 20 is arranged at the upper end of the first winding portion 10, and the second flange portion 30 is arranged at the lower end of the first winding portion 10. The mounting portion 40 is arranged at the outer periphery of the first flange portion 20, for example, the mounting portion 40 is arranged at the outer periphery position of about one fourth of the first flange portion 20. At least one first through hole 41 is arranged on the mounting portion 40, that is, the first through hole 41 is arranged to pass through, which can be used for mounting the pin 200, that is, the pin 200 can be mounted in the first through hole 41, and the winding wire can be connected to the pin 200 and the like during mounting.

The pin 200 is located on the other side of the blocking portion 50, and the metal beads generated during the metal processing of the pin 200 can be blocked by the blocking portion 50 from rolling to the gear assembly 500. For example, when the pin 200 is tin-plated, the tin beads after soldering can be prevented from entering the inside of the gear assembly 500, causing the gear assembly 500 to jam or even be stuck, and avoiding abnormal noise.

[0130] Therefore, according to the coil former 100 of the present embodiment, the metal beads generated during the metal processing of the pin 200 can be blocked by the blocking portion 50 from rolling to the gear assembly 500, which can effectively prevent the gear assembly 500 from being affected by the metal beads, for example, causing the motor to jam, be stuck, and produce abnormal noise, and the like due to tin-plating.

[0146] In the direction away from the axis of the first winding part 10 from the blocking part 50, a force is applied to the first section 201 to drive the first section 201 to bend.

[0147] That is, in the direction parallel to the axis of the first winding part 10, the highest end of the pin 200 is higher than the highest end of the blocking part 50. For example, in the up-down direction, the uppermost end of the pin 200 mounted in the first through hole 41 is higher than the position of the uppermost end of the blocking part 50, and during the mounting process, a force can be applied to the upper end of the pin 200 from the inside of the mounting part 40 through the blocking part 50 to drive the upper end of the pin 200 to bend outward. In this embodiment, by limiting the position of the highest end of the pin 200, the upper part of the pin 200 mounted in the first through hole 41 can be forced in the direction from inside to outside through the blocking part 50 during the mounting process to drive the upper part of the pin 200 to bend outward.

[0148] According to one embodiment of the present application, the first through hole 41 and the number of pins 200 are respectively multiple and one-to-one correspondence, and a force is applied to the multiple first sections 201 simultaneously in the direction away from the axis of the first winding part 10 from the blocking part 50. By providing multiple first through holes 41, it is convenient to simultaneously mount multiple pins 200, and it is convenient to simultaneously bend multiple pins 200 and the like. Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by distributing multiple first through holes 41 along the extension direction of the mounting part 40, it is beneficial to control the orderly arrangement of multiple pins 200 on the mounting part 40, and it is beneficial to the subsequent mounting of the first cover plate 60 and the second cover plate 70.

[0149] The present application also provides an assembly method of a coil assembly, the blocking part 50 is spaced apart from the first through hole 41 to form a gap 49 in the direction of the axis of the first winding part 10 from the mounting part 40, and the blocking part 50 can block the metal beads generated during the metal processing of the pin 200 from rolling in the direction of the axis of the first winding part 10;

[0150] The assembly method comprises the following steps:

[0151] The pin 200 is installed in the first through hole 41, and the pin 200 includes a first segment 201, a second segment 202 and a third segment 203, the first segment 201 extends out of the first through hole 41 and is located on the same side of the blocking part 50 as the mounting part 40, the second segment 202 is located in the first through hole 41, and the third segment 203 extends out of the first through hole 41 and extends towards one side of the second hammer-shaped part 30;

[0153] That is, in the axial direction of the first winding part 10 from the mounting part 40, the blocking part 50 is spaced apart from the first through hole 41 to form a gap 49. That is, in one direction from the outside to the inside, the first through hole 41, the gap 49 and the blocking part 50 are arranged in sequence. In this embodiment, by providing the gap 49, during installation, the upper part of the pin 200 installed in the first through hole 41 can be forced through the gap 49, and the upper part of the pin 200 is driven to bend outward, for example, the pin 200 in the first through hole 41 extends in the up-down direction, and the pin 200 above the first through hole 41 bends outward relative to the pin 200 in the first through hole 41 after an external force is applied.

[0154] It should be noted that the highest end of the pin 200 can be individually satisfied in the axial direction parallel to the first winding part 10, and the highest end of the blocking part 50 can be individually satisfied in the axial direction of the first winding part 10 from the mounting part 40, and the gap 49 is spaced apart from the first through hole 41 to form a gap 49, and the above conditions can also be satisfied at the same time, and the bending mode can be variously set according to product design requirements.

[0155] According to one embodiment of the present application, the number of first through holes 41 and pins 200 is multiple and one-to-one correspondence, and the gap 49 exerts a force on the multiple first segments 201 away from the blocking part 50 to drive the multiple first segments 201 to bend simultaneously.

In addition, by spacing multiple first through holes 41 along the extension direction of the mounting part 40, it is beneficial to control the orderly arrangement of multiple pins 200 on the mounting part 40, and it is beneficial to the subsequent installation of the first cover plate 60 and the second cover plate 70.

[0156] In addition, when the number of pins 200 is multiple, the mounting part 40 can adopt a plastic structure, or the inner wall of the first through hole 41 is coated with an insulating material to realize insulation between adjacent two pins 200 to prevent short circuit.

[0157] In some embodiments of the present application, the gap 49 is open on one side away from the mounting portion 40 in a direction parallel to the axis of the first winding portion 10, for example, the height direction of the gap 49 is the up-down direction, and the gap 49 is open upward, so that the force applying tool can be inserted from the top.

[0158] According to one embodiment of the present application, the blocking portion 50 extends in a direction perpendicular to the axis of the first winding portion 10, and at least one side of the gap 49 is open in the extension direction of the blocking portion 50. For example, the length direction of the gap 49 is the left-right direction, and the left and right sides of the gap 49 are open, so that the force applying tool can be inserted through the open position.

[0159] It should be noted that the gap 49 can be open on one side away from the mounting portion 40 in a direction parallel to the axis of the first winding portion 10, or the gap 49 can be open on at least one side in the extension direction of the blocking portion 50, or both conditions can be met at the same time. The bending mode of the pin 200 is various and flexible.

[0160] In some embodiments of the present application, the blocking portion 50 is a solid structure, which can expand the range of the blocking metal beads and facilitate processing and production.

[0161] In some embodiments of the present application, as shown in Figure 5 The motor framework further includes a second framework 300, which includes a second winding portion 301, a third tamper portion 302, and a fourth tamper portion 303.

The third tamper portion 302 is arranged at one end of the second winding portion 301 in the axial direction, and the fourth tamper portion 303 is arranged at the other end of the second winding portion 301 in the axial direction. The third tamper portion 302 is connected to the second tamper portion 30, and as shown in Figure 6 The connection position of the two is provided with a clearance groove 304 to avoid the third section body 203 and affect the bending of the pin 200 and the lead wire 400. In addition, the first cover plate 60 inner wall can also be avoided, and the first cover plate 60 is facilitated to be installed.

[0162] The mounting portion 40 according to the embodiment of the present application will be described in detail below.

[0163] The mounting portion 40 is arranged on the outer periphery of the first flange portion 20. The mounting portion 40 is provided with a first through hole 41 for mounting the pin 200. The outer surface of the mounting portion 40 includes a first surface 42, a second surface 43 and a third surface 44. The first surface 42 and the third surface 44 are spaced apart and connected by the second surface 43. One end of the first through hole 41 is communicated with the first surface 42, and the other end of the first through hole 41 is communicated with the third surface 44. The outer side of the mounting portion 40 is provided with an open slot 48 spaced apart from the first through hole 41.

The included angle between the third surface 44 and the second surface 43 is obtuse.

[0164] In other words, the mounting portion 40 is arranged on the outer periphery of the first flange portion 20, for example, the mounting portion 40 is arranged on the outer periphery of about one fourth of the first flange portion 20. The mounting portion 40 is provided with at least one first through hole 41, that is, the first through hole 41 is provided through. The first through hole 41 can be used for mounting the pin 200, that is, the pin 200 can be mounted in the first through hole 41. When mounting, the winding wire can be connected to the pin 200 and the like. In this embodiment, the shape of the cross section of the pin 200 is not limited, for example, the cross section of the pin 200 is square, which can prevent the winding wire from sliding.

[0165] The outer surface of the mounting portion 40 mainly includes the first surface 42, the second surface 43 and the third surface 44. The first surface 42 and the third surface 44 are spaced apart, for example, spaced apart in the direction parallel to the axis of the first winding portion 10 and connected by the second surface 43. That is, the first surface 42 and the third surface 44 are connected in an indirect connection mode. The second surface 43 is connected with the first surface 42 and the third surface 44 respectively. Moreover, part of the first through hole 41 is arranged on the first surface 42, and another part is arranged on the third surface 44. That is, one end of the first through hole 41 is communicated with the first surface 42, and the other end of the first through hole 41 is communicated with the third surface 44.

[0166] The outer side of the mounting portion 40 is provided with an open slot 48 spaced apart from the first through hole 41. Part of the open slot 48 is arranged on the first surface 42, another part is arranged on the second surface 43, and the other part is arranged on the third surface 44. That is, the open slot 48 is communicated with the first surface 42, the second surface 43 and the third surface 44 respectively. In this embodiment, the winding wire on the first winding portion 10 can be connected with the part of the pin 200 protruding out of the first through hole 41 through the open slot 48. For example, the upper part of the pin 200 protrudes out of the upper end of the first through hole 41 and is connected with the winding wire. In this embodiment, the position of the winding wire can be limited by arranging the open slot 48, which can avoid the interference between the winding wire and other structures, and improve the efficiency and safety of the winding wire.

[0167] The included angle between the third surface 44 and the second surface 43 is obtuse, for example, the second surface 43 extends substantially in the vertical direction, the third surface 44 is located below the first surface 42, and the included angle between the third surface 44 and the second surface 43 is obtuse, the third surface 44 is inclined relative to the second surface 43, which can buffer the bending degree of the winding wire connected between the mounting portion 40 and the first winding portion 10, and avoid the winding wire being cut off due to the outer surface of the mounting portion 40.

[0168] According to one embodiment of the present application, as shown in Figure 4 The first surface 42 and the second surface 43 are connected by a first circular arc surface 45, and / or the second surface 43 and the third surface 44 are connected by a second circular arc surface 46. By using the transition connection, the winding wire can be further protected, and the winding wire can be routed smoothly.

[0169] In some embodiments of the present application, the second surface 43 is closer to the second tamper 30 relative to the first surface 42, for example, the first tamper 20 is located above the second tamper 30, and the first surface 42 is located above the second surface 43. In the up-down direction, the second surface 43 is closer to the second tamper 30 relative to the first surface 42. In this embodiment, by using the second surface 43 closer to the second tamper 30 relative to the first surface 42, the winding wire can enter the open slot 48 at a shorter distance after being wound by the first winding portion 10.

[0170] According to one embodiment of the present application, the first through hole 41 includes a first hole section 411 and a second hole section 412.

For example, the first through hole 41 includes the first hole section 411 and the second hole section 412 distributed in the up-down direction, the upper end of the first hole section 411 communicates with the first surface 42, the upper end of the second hole section 412 communicates with the lower end of the first hole section 411, and the lower end of the second hole section 412 communicates with the second surface 43 and the third surface 44. In this embodiment, since the second hole section 412 communicates with the second surface 43 and the third surface 44, one end of the pin 200 can extend out through the first hole section 411, the other end of the pin 200 can be bent outward toward the side where the second surface 43 is located, and can also have a certain distance from the third surface 44, avoiding contact with the winding wire passing through the third surface 44.

[0172] In some embodiments of the present application, as Figure 3As shown, the coil former 100 further comprises a blocking portion 50 protruding from the first surface 42 and located on the side of the first through hole 41 close to the axis direction of the first winding portion 10, the blocking portion 50 can block the metal beads generated during the metal processing of the pin 200 from rolling towards the axis direction of the first winding portion 10. That is, the blocking portion 50 protrudes from the surface of the mounting portion 40 away from the side of the second clavate portion 30 and is located on the side of the first through hole 41 close to the axis direction of the first winding portion 10.

And the pin 200 is located on the other side of the blocking portion 50, and the blocking portion 50 can block the metal beads generated during the metal processing of the pin 200 from rolling to the gear assembly 500. For example, when the pin 200 is tinned, the tin beads after soldering can be prevented from entering the inside of the gear assembly 500, causing jamming or even being stuck.

[0175] According to an embodiment of the present application, the mounting portion 40 has a length direction, a thickness direction and a height direction, the length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to one radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10, the first surface 42 and the third surface 44 are spaced apart in the height direction, and the second surface 43 is located on one side of the mounting portion 40 in the thickness direction.

[0176] That is, the long edge of the mounting portion 40 extends along the length direction of itself, the thick edge extends along the thickness direction of itself, and the high edge extends along the height direction of itself. The length direction is perpendicular to the axis direction of the first winding portion 10, the thickness direction is parallel to one radial direction of the first winding portion 10, and the height direction is parallel to the axis direction of the first winding portion 10, for example, the height direction is the Z-axis direction, the thickness direction is the X-axis direction, and the length direction is the Y-axis direction.

Each first through hole 41 can correspond to one pin 200, which can increase the total number of pins 200. In addition, by distributing the plurality of first through holes 41 along the length direction, it is beneficial to control the orderly arrangement of the plurality of pins 200 on the mounting portion 40, and facilitate the subsequent installation of the first cover plate 60 and the second cover plate 70. In addition, when the number of pins 200 is large, the mounting portion 40 can be made of plastic, or the inner wall of the first through hole 41 is coated with an insulating material to achieve insulation between adjacent two pins 200 and prevent short circuit.

[0179] That is to say, in the present embodiment, the outer surface of the mounting portion 40 mainly comprises the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47, the fourth surface 47 is connected to the third surface 44 and the first gong-shaped portion 20 respectively, and the third surface 44 is indirectly connected to the first gong-shaped portion 20. The first part of the open groove 48 is arranged on the first surface 42, the second part is arranged on the second surface 43, the third part is arranged on the third surface 44, and the fourth part is arranged on the fourth surface 47, that is, the open groove 48 simultaneously communicates with the first surface 42, the second surface 43, the third surface 44 and the fourth surface 47. In addition, the fourth surface 47 is parallel to the first surface 42, which is convenient for processing.

[0180] In the present embodiment, by adopting the fourth surface 47, the area of the region for processing the third surface 44 on the mounting portion 40 can be reduced, which is convenient for processing. In addition, by connecting the open groove 48 to the fourth surface 47, not only is it convenient to process the open groove 48 on the outer surface of the mounting portion 40, but also it can avoid the wall edge of the open groove 48 rubbing the winding wire.

[0181] According to one embodiment of the present application, in the thickness direction, the end of the opening slot 48 on the third surface 44 is closer to the central axis of the first winding portion 10 than the first through hole 41 on the third surface 44. For example, the opening slot 48 on the third surface 44 extends inwardly, the minimum distance between the inner wall of the opening slot 48 on the third surface 44 and the central axis of the first winding portion 10 is L1, and the minimum distance between the inner wall of the first through hole 41 adjacent to the opening slot 48 on the third surface 44 and the central axis of the first winding portion 10 is L2, L1 < L2. In this embodiment, in the thickness direction, the end of the opening slot 48 on the third surface 44 is closer to the central axis of the first winding portion 10 than the first through hole 41 on the third surface 44, which is beneficial to the protection of the winding wire and avoids the winding wire from contacting the pin 200 passing through the first through hole 41 on the third surface 44.

[0182] In some embodiments of the present application, in the thickness direction, the first through hole 41 on the first surface 42 is closer to the central axis of the first winding portion 10 than the opening slot 48 on the first surface 42.

[0183] According to one embodiment of the present application, in the height direction, the width dimension of the end of the opening slot 48 away from the second tamper portion 30 is smaller than the width dimension of the end of the opening slot 48 close to the second tamper portion 30. For example, the axis direction of the first winding portion 10 is the up-down direction, the second tamper portion 30 is located below the first tamper portion 20, and the width dimension of the upper end of the opening slot 48 is smaller than the width dimension of the lower end of the opening slot 48. The upper section of the opening slot 48 can be a straight slot section extending in the up-down direction, and the lower section of the opening slot 48 can be a trumpet-shaped slot section with a narrow upper part and a wide lower part extending in the up-down direction. In this embodiment, by limiting the shape of the opening slot 48, the protection effect on the winding wire can be improved, and the winding wire in the first winding portion 10 and the opening slot 48 is prevented from being disconnected due to the edge friction of the opening slot 48.

[0186] The inner wall surface of the second cover plate 70 opposite to the first cover plate 60 is provided with a plurality of second clamping portions 72 and a plurality of crimping protrusions 74. A second groove 73 is formed between two adjacent second clamping portions 72, or a second groove 73 is formed between the second clamping portion 72 and the edge of the second cover plate 70.
