[0002] As the core structure of the motor, the wiring structure of the motor plays a vital role in the cost and safety of the motor. Therefore, by improving the installation method of the motor and its socket components, the installation efficiency and motor cost of the existing motor can be improved. In the related scheme, a terminal block is generally provided on the motor, and the terminal block is generally fixed on the motor through a wire package. However, in this way, the position of the terminal block is prone to movement, which can easily lead to poor wiring of the motor. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] In view of this, one object of the present invention is to provide a motor assembly.

[0005] Another object of the present invention is to provide a refrigeration device.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the first aspect of the utility model provides a motor assembly, including: a motor, the motor including a stator core and a plurality of coils wound on the stator core, the stator core including a first end face; a terminal block fixedly mounted on the motor, and at least a portion of the terminal block abuts against the first end face. Wherein, the terminal block includes: a seat body; a wiring portion, arranged on the seat body, for connecting the socket component; two arc-shaped mounting portions, arranged on both ends of the seat body arranged along the circumference of the motor, and extending along the circumference of the motor, the arc-shaped mounting portion is wound and mounted on the circumference of the motor by the coil; at least two guide columns, arranged on the seat body at intervals along the circumference of the motor, the guide columns extend in a direction away from the wiring portion, and a plurality of guide columns are used to be inserted between two adjacent coils; the guide column and the arc-shaped mounting portion are arranged at intervals along the axial direction of the motor, and the arc-shaped mounting portion is arranged near the top of the motor relative to the guide column; at least a portion of the end face of the end of the guide column arranged near the stator core abuts against the first end face.

[0007] The motor assembly provided in the present application includes a motor and a terminal block. The terminal block is fixedly mounted on the motor by a wire package, that is, the terminal block is arranged between the wire package and the motor, that is, when the wire package is wound around the motor, it is also wound around the terminal block, thereby realizing the connection between the terminal block and the motor, and the connection method is simple and efficient. Specifically, the wire package wraps the arc-shaped mounting portion of the terminal block around the circumference of the motor, that is, the arc-shaped mounting portion fits the circumference of the motor and is wrapped by the wire package. Since the circumference of the motor is generally arc-shaped, the arc-shaped mounting portion is correspondingly arc-shaped, so that the fitting area is larger, which is conducive to increasing the area of ​​the arc-shaped mounting portion that can be fixed by winding the wire package, and further improving the stability and reliability of the connection between the terminal block and the motor.

[0008] Furthermore, the terminal block is installed on the motor for electrical connection between the motor and the socket, that is, the winding on the motor can be connected to the terminal block, and the socket is also connected to the terminal block at the same time, so that the electrical connection between the motor and the socket can be achieved. Wherein, for the motor, a winding is arranged on it, for example, for the stator assembly, a stator winding is arranged, and the stator winding is wound on each stator tooth of the stator core, so that a coil is formed on each stator tooth. The terminal block includes a seat body, a wiring part, two arc-shaped mounting parts and at least two guide posts. Wherein, the wiring part is used for wiring, and the lead wire drawn out from the socket can be connected to the wiring part. The winding can also be connected to the wiring part, so that the electrical connection between the winding and the socket can be achieved. The arc-shaped mounting part is used to fit the side wall surface of the motor, and then is wound and fixed on the motor by the winding, so that the terminal block can be installed on the motor, and the guide post is used to be inserted into the gap formed by the two coils. During installation, the guide column can be inserted into the wire package first to achieve the initial position fixation of the terminal block, and then the outlet end of the winding can be wrapped around the arc-shaped mounting portion to achieve the binding fixation of the arc-shaped mounting portion. Among them, in the present application, the number of guide columns is multiple, so that the multi-point positioning of the wire package to the terminal block can be achieved through the cooperation of multiple guide columns and multiple wire packages, thereby improving the fixing strength of the wire package to the terminal block, avoiding the terminal block from shifting during wiring, and ensuring the accuracy of the installation position of the terminal block. Furthermore, this setting can also improve the installation strength of the wire package to the terminal block, avoiding the problem of poor wiring due to misalignment of the terminal block when the motor is working. At the same time, in the present application, the arc-shaped mounting portion is arranged near the top of the motor relative to the guide column, that is, the arc-shaped mounting portion is arranged higher, and the guide column is arranged lower, so that the guide column can be installed on the upper end surface of the stator core, etc., so as to axially position the entire terminal block through the upper end surface of the stator core, etc., so as to avoid the terminal block from being tilted during installation, and at the same time, it can also avoid the terminal block from tilting up and down due to the vibration of the motor when the motor is working. Once the position of the terminal block tilts up and down, the position of the lead-out wire of the socket and the terminal of the winding will be offset and misaligned, which will cause poor wiring of the motor, so that the motor cannot work normally. And through the positioning of the guide column and the upper end surface of the stator core, that is, the first end surface, the terminal block can be prevented from moving along the axial direction of the motor, so that the position of the terminal block can be stabilized, so as to ensure the connection stability between the motor and the socket, and solve the problem that the existing motor is prone to poor wiring. In addition, this structure can simply and conveniently realize the connection between the motor and the socket component, which is conducive to improving the installation efficiency of the motor and the socket component.

[0009] Among them, the guide column and the arc-shaped mounting portion are arranged at intervals, which makes it easy for the guide column and the arc-shaped mounting portion to fit or abut against different surfaces on the motor, so as to improve the accuracy of positioning and installation.

[0010] Specifically, an arc-shaped mounting portion that can be fitted with the motor is provided on the seat body, so that when the arc-shaped mounting portion is connected to the motor, it occupies a small space and is easy to be tightly connected to the motor as a whole; further, the arc-shaped mounting portion can fit with the motor, and it is also convenient for the wire package on the motor to pass around the arc-shaped mounting portion and wrap the arc-shaped mounting portion around the motor, thereby tightly connecting the terminal block and the motor together; the terminal block includes a seat body and a wiring portion that are connected to each other, and the wiring portion is connected to a socket component, thereby realizing the connection between the motor and the socket component. Such a connection structure is simple, efficient and easy to operate.

[0011] Optionally, there are three guide posts, so that the number of guide posts is moderate, thus ensuring the installation stability between the wire package and the terminal block while avoiding the structure of the terminal block being too complicated.

[0012] Optionally, the number of guide posts is at least 2, and the at least 2 guide posts include a first guide post and a second guide post, the second guide post is arranged on one side of the first guide post, and the end of the second guide post away from the base body extends obliquely in a direction close to the first guide post. Further, the at least 2 guide posts also include a third guide post, the third guide post is arranged on the other side of the first guide post, and the end of the third guide post away from the base body extends obliquely in a direction close to the first guide post.

[0013] In this technical solution, multiple guide posts are not arranged completely in parallel, wherein the first guide post is arranged along the radial direction of the stator, and the second guide posts or the third guide posts on both sides of the first guide post are not arranged in parallel with the first guide post, but are arranged closer to the free end, closer to the first guide post. This arrangement allows the second guide post and / or the third guide post to be arranged close to the first guide post, so that after the three guide posts are inserted into the wire package, a clamping structure can be formed by the first guide post and the second guide post, and / or the first guide post and the third guide post to clamp the wire package, thereby improving the bonding force between the wiring dome and the wire package and ensuring the installation stability between the two.

[0014] Among them, in the actual solution, only the second guide column can be provided without the third guide column, or the second guide column and the third guide column can be provided at the same time.

[0015] Exemplarily, the three guide posts include a first guide post, a second guide post and a third guide post are respectively arranged on both sides of the first guide post, and the second guide post and the third guide post extend obliquely from one end of the base body toward the first guide post.

[0016] In this technical solution, multiple guide posts are not arranged completely in parallel, wherein the first guide post, i.e. the middle guide post, is arranged along the radial direction of the stator, while the second guide post and the third guide post on both sides of the first guide post are not arranged parallel to the first guide post, but are arranged closer to the first guide post as they are closer to the free end. This arrangement allows the second guide post and the third guide post to be arranged close to the first guide post, so that after the three guide posts are inserted into the wire package, a clamping structure can be formed by the first guide post and the second guide post, as well as the first guide post and the third guide post to clamp the wire package, thereby improving the bonding force between the wiring dome and the wire package and ensuring the installation stability between the two.

[0017] Optionally, the length of the guide post can be adjusted. For different motor models, the radius of the stator core is not exactly the same, and the thickness of the coil is not exactly the same. However, in the terminal block in the related scheme, the length of the guide post cannot be adjusted according to the radial size of the coil, so that one terminal block can only adapt to one type of motor, and cannot adapt to multiple motors with different coil sizes. This makes the flexibility of the terminal block poor. In view of the above problems, the present application provides a guide post with adjustable length, so that the length of the guide post can be adjusted to different lengths according to actual needs, thereby improving the applicability of the terminal block to motors of different models.

[0018] Furthermore, the guide column comprises a base and a telescopic rod, wherein a receiving cavity is arranged in the base, and one end of the telescopic rod can be slidably mounted in the receiving cavity. The telescopic rod can be extended or retracted by sliding the telescopic rod, thereby adjusting the length of the guide column.

[0019] Furthermore, the guide column also includes a locking piece, the extension length of the telescopic rod can be adjusted at will, and the telescopic rod can be locked at one or more positions by the locking piece after adjustment. Further, the telescopic rod can be locked at any position by the locking piece after adjustment, thereby realizing infinite adjustment of the length of the guide column.

[0020] Furthermore, the wiring seat is a plastic seat, so that the wiring seat has a certain elasticity. Specifically, the guide post has a certain elasticity, so that the guide post can be deformed to a certain extent, so that through the deformation of the guide post, the two guide posts can clamp the wire package more securely.

[0021] Optionally, the terminal block further includes a protective sleeve, which is mounted on the guide column. The protective sleeve can enhance the flexibility of the guide column and prevent the guide column from directly contacting the wire package and scratching the wire package. The protective sleeve can be a tape or cloth strip wound around the guide column. The protective sleeve can also be an elastic rubber sleeve directly mounted on the guide column.

[0022] Optionally, first protrusions are provided at both ends of the arc-shaped mounting portion along the circumference of the motor, and the first protrusions extend in a direction close to the wiring portion.

[0023] In this technical solution, in order to prevent the wires wound on the arc-shaped mounting portion from slipping off the arc-shaped mounting portion, a first protrusion is provided at both ends of the arc-shaped mounting portion, and the wires on the arc-shaped mounting portion can be limited on the arc-shaped mounting portion by the first protrusion, so that the position of the wire package can be accurately defined, and the wire package can be prevented from falling off the arc-shaped mounting portion, resulting in failure of the connection between the arc-shaped mounting portion and the motor, thereby improving the reliability and stability of the connection between the arc-shaped mounting portion and the motor.

[0024] Optionally, a plurality of second protrusions are provided at intervals on one side of the arc-shaped mounting portion close to the wiring portion; an extension height of the second protrusions in a direction close to the wiring portion is lower than an extension height of the first protrusions in a direction close to the wiring portion.

[0025] In this technical solution, by providing a plurality of spaced second protrusions on one side of the arc-shaped mounting portion close to the wiring portion, the wire package of the motor can be limited when it is wound onto the arc-shaped mounting portion, so that the wires on the arc-shaped mounting portion are evenly dispersed, avoiding the wire packages on the arc-shaped mounting portion from gathering together, thereby improving the uniformity of force on the arc-shaped mounting portion.

[0026] Optionally, the terminal block further comprises: a positioning block, which is arranged on the seat body, spaced apart from the arc-shaped mounting portion along the axial direction of the motor and extends in a direction away from the terminal block, and at least two guide posts are arranged on a side of the positioning block away from the terminal block; wherein an end face of the positioning block away from the arc-shaped mounting portion and an end face of the guide post away from the arc-shaped mounting portion are flush with each other. At least a portion of an end face of the positioning block close to the stator core is in contact with the first end face.

[0027] In this technical solution, the positioning block can be axially abutted against the motor, so that it is convenient to position the terminal block axially when connecting the motor and the terminal block, which is beneficial to improve the installation stability of the terminal block and avoid the terminal block from being offset. The guide column is set on the positioning block, so that the connection between the guide column and the seat body can be realized. The positioning block can shorten the length of the guide column to avoid the situation where the guide column is too long and the strength of the guide column is insufficient. The end face of the positioning block away from the arc-shaped mounting portion and the end face of the guide column away from the arc-shaped mounting portion are flush with each other, that is, the bottom wall surface of the positioning block and the guide column are flush, so that a larger abutment surface can be formed for abutting and positioning with an end face of the motor, so that the bottom support surface of the terminal block can be increased, thereby improving the installation stability of the terminal block, and making the terminal block less likely to tilt.

[0028] Optionally, the arc-shaped mounting portion is flush with the end surface of the seat body near the top of the motor. This arrangement can make the upper end surface of the wiring seat form a plane, thereby improving the aesthetics of the product and reducing the overall height of the product.

[0029] Optionally, the arc-shaped mounting portion extends to both sides of the seat body, and the two arc-shaped mounting portions are symmetrically arranged with respect to the seat body.

[0030] In this technical solution, the arc-shaped mounting portion is arranged to extend to both sides of the seat body so that the position of the seat body is roughly located in the middle of the arc-shaped mounting portion. When the terminal socket and the motor are connected, the portions of the arc-shaped mounting portion extending to both sides of the seat body can be wrapped with the wire package, so that both sides of the arc-shaped mounting portion are wrapped around the motor, and the arc-shaped mounting portion and the terminal socket are subjected to force more evenly, avoiding unstable connection caused by biasing to one side, thereby improving the stability and reliability of the connection between the motor and the terminal socket.

[0031] In any of the above technical solutions, the wiring portion includes: a mounting hole and a mounting groove that are interconnected, and the mounting groove is used to guide the lead wire on the socket component to extend into the mounting hole.

[0032] In this technical solution, by providing mounting holes and mounting grooves, it is convenient to provide guidance and installation positioning for the leads on the socket component, ensuring the convenience and efficiency of the connection between the leads and the terminal block.

[0033] In any of the above technical solutions, the socket component includes a socket and a lead, one end of the lead is connected to the socket, and the other end of the lead extends into the mounting hole on the wiring base along the mounting groove on the wiring base.

[0034] In this technical solution, by setting the socket component to include a socket and a lead, one end of the lead is connected to the socket, and the other end of the lead extends into the mounting hole on the terminal block along the mounting groove on the terminal block, thereby realizing the connection between the socket component and the terminal block, and then realizing the connection between the socket component and the motor.

[0035] The technical solution of the second aspect of the utility model provides a refrigeration device, including a motor assembly of any one of the technical solutions of the first aspect.

[0036] In this technical solution, by adopting the motor component preparation equipment of any one of the technical solutions in the first aspect above, all the beneficial effects of the above technical solutions are achieved, which will not be repeated here.

[0037] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 7 Some embodiments according to the present invention are described.

[0050] like Figures 1 to 7As shown, an embodiment of the first aspect of the utility model provides a motor assembly, comprising: a motor 2, the motor 2 comprising a stator core and a plurality of windings wound on the stator core, the stator core comprising a first end face 22; a terminal block 1, fixedly mounted on the motor 2, and at least a portion of the terminal block 1 abuts against the first end face 22. Among them, the terminal block 1 includes: a seat body 10; a wiring portion 12, which is arranged on the seat body 10 and is used to connect a socket component; two arc-shaped mounting portions 16, which are arranged on both ends of the seat body 10 along the circumference of the motor 2 and extend along the circumference of the motor 2, and the arc-shaped mounting portions 16 are installed on the circumferential surface of the motor 2 by winding the wire package; at least two guide columns 14 are arranged on the seat body 10 at intervals along the circumference of the motor 2, and the guide columns 14 extend in a direction away from the wiring portion 12, and multiple guide columns 14 are used to be inserted between two adjacent wire packages; the guide columns 14 and the arc-shaped mounting portions 16 are arranged at intervals along the axial direction of the motor 2, and the arc-shaped mounting portions 16 are arranged near the top of the motor 2 relative to the guide columns 14; at least a portion of the end face of one end of the guide column 14 arranged near the stator core abuts against the first end face 22.

[0051] The motor assembly provided in the present application includes a motor 2 and a terminal block 1. The terminal block 1 is fixedly mounted on the motor 2 by a wire package, that is, the terminal block 1 is arranged between the wire package and the motor 2, that is, when the wire package is wound around the motor 2, it is also wound around the terminal block 1, thereby realizing the connection between the terminal block 1 and the motor 2, and the connection method is simple and efficient. Specifically, the wire package wraps the arc-shaped mounting portion 16 of the terminal block 1 around the circumference of the motor 2, that is, the arc-shaped mounting portion 16 fits the circumference of the motor 2 and is wrapped by the wire package. Since the circumference of the motor 2 is generally arc-shaped, the arc-shaped mounting portion 16 is correspondingly arc-shaped, so that the fitting area is larger, which is conducive to increasing the area of ​​the arc-shaped mounting portion 16 that can be fixed by the wire package winding, and further improving the stability and reliability of the connection between the terminal block 1 and the motor 2.

[0052] Furthermore, if Figure 3 and Figure 4As shown, the terminal block 1 is installed on the motor 2 for electrical connection between the motor 2 and the socket, that is, the winding on the motor 2 can be connected to the terminal block 1, and the socket is also connected to the terminal block 1 at the same time, so that the electrical connection between the motor 2 and the socket can be achieved. Wherein, for the motor 2, a winding is arranged on it, for example, for the stator assembly, a stator winding is arranged, and the stator winding is wound on each stator tooth of the stator core, so that a coil is formed on each stator tooth. The terminal block 1 includes a seat body 10, a wiring portion 12, two arc-shaped mounting portions 16 and at least two guide columns 14. Wherein, the wiring portion 12 is used for wiring, and the lead wire drawn out from the socket can be connected to the wiring portion 12. The winding can also be connected to the wiring portion 12, so that the electrical connection between the winding and the socket can be achieved. The arc-shaped mounting portion 16 is used to fit the side wall surface of the motor 2, and then is wound and fixed on the motor 2 by the winding, so that the terminal block 1 can be installed on the motor 2, and the guide column 14 is used to be inserted into the gap formed by the two coils. During installation, the guide column 14 can be first inserted into the wire package to achieve the initial position fixation of the terminal block 1, and then the outlet end of the winding can be wrapped around the arc-shaped mounting portion 16 to achieve the binding fixation of the arc-shaped mounting portion 16. Among them, in the present application, the number of guide columns 14 is multiple, so that the multi-point positioning of the wire package to the terminal block 1 can be achieved through the cooperation of multiple guide columns 14 and multiple wire packages, thereby improving the fixing strength of the wire package to the terminal block 1, avoiding the terminal block 1 from shifting during wiring, thereby ensuring the accuracy of the installation position of the terminal block 1. Furthermore, this setting can also improve the installation strength of the wire package to the terminal block 1, avoiding the problem of poor wiring due to misalignment of the terminal block 1 when the motor 2 is working. At the same time, in the present application, the arc-shaped mounting portion 16 is arranged near the top of the motor 2 relative to the guide column 14, that is, the arc-shaped mounting portion 16 is arranged higher, while the guide column 14 is arranged lower, so that the guide column 14 can be installed on the upper end surface of the stator core, etc., so as to axially position the entire terminal block 1 through the upper end surface of the stator core, etc., so as to avoid the terminal block 1 from being tilted during installation, and also avoid the terminal block 1 from tilting up and down due to the vibration of the motor 2 when the motor 2 is working. Once the position of the terminal block 1 tilts up and down, the position of the lead-out wire terminal of the socket and the terminal of the winding will be offset and misaligned, which will cause poor wiring of the motor 2, so that the motor 2 cannot work normally. And through the positioning of the guide column 14 and the upper end surface of the stator core, that is, the first end surface 22, the terminal block 1 can be prevented from moving along the axial direction of the motor 2, so that the position of the terminal block 1 can be stabilized, so as to ensure the connection stability between the motor 2 and the socket, and solve the problem that the existing motor 2 is prone to poor wiring. In addition, this structure can simply and conveniently realize the connection between the motor 2 and the socket component, which is helpful to improve the installation efficiency of the motor 2 and the socket component.

[0053] Optionally, the length of the guide column 14 can be adjusted. For different models of motors 2, the radius of the stator core is not exactly the same, and the thickness of the coil is not exactly the same. However, in the terminal block 1 in the related scheme, the length of the guide column 14 cannot be adjusted according to the radial size of the coil, so that one terminal block 1 can only adapt to one type of motor 2, and cannot adapt to multiple motors 2 with different coil sizes. This makes the flexibility of the terminal block 1 poor. In view of the above-mentioned problems, the present application provides a guide column 14 with adjustable length, so that the length of the guide column 14 can be adjusted to different lengths according to actual needs, thereby improving the applicability of the terminal block 1 to motors 2 of different models.

[0054] Furthermore, if Figure 2 As shown, the guide column 14 includes a base 142 and a telescopic rod 144. A receiving cavity is provided in the base 142, and one end of the telescopic rod 144 can be slidably installed in the receiving cavity. The telescopic rod 144 can be extended or retracted by sliding, so that the length of the guide column 14 can be adjusted.

[0055] Furthermore, the guide column 14 also includes a locking piece, and the extension length of the telescopic rod can be adjusted at will, and the telescopic rod can be locked at one or more positions by the locking piece after adjustment. Further, the telescopic rod can be locked at any position by the locking piece after adjustment, thereby realizing the infinite adjustment of the length of the guide column 14.

[0056] Furthermore, the wiring seat 1 is a plastic seat, so that the wiring seat 1 has a certain elasticity. Specifically, the guide post 14 has a certain elasticity, so that the guide post 14 can be deformed to a certain extent, so that through the deformation of the guide post 14, the two guide posts 14 can clamp the wire package more securely.

[0057] Optionally, the wiring socket 1 further includes a protective sleeve (not shown in the figure), which is mounted on the guide column 14. The protective sleeve can enhance the flexibility of the guide column 14 to prevent the guide column 14 from directly contacting the wire package and scratching the wire package. The protective sleeve can be a tape or cloth strip wound around the guide column 14. The protective sleeve can also be an elastic rubber sleeve directly mounted on the guide column 14.

[0058] Among them, Figure 5 As shown, the guide column 14 and the arc-shaped mounting portion 16 are spaced apart to facilitate the guide column 14 and the arc-shaped mounting portion 16 to fit or abut against different surfaces of the motor 2 to improve the accuracy of positioning and mounting.

[0059] Specifically, the seat body 10 is provided with an arc-shaped mounting portion 16 that can be fitted with the motor 2, so that when the arc-shaped mounting portion 16 is connected to the motor 2, it occupies a small space and is easy to be tightly connected to the motor 2 as a whole; further, the arc-shaped mounting portion 16 can fit with the motor 2, and it is also convenient for the wire package on the motor 2 to pass around the arc-shaped mounting portion 16 and wrap the arc-shaped mounting portion 16 around the motor 2, thereby tightly connecting the terminal block 1 and the motor 2 together; and the terminal block 1 includes a seat body 10 and a wiring portion 12 that are interconnected, and the wiring portion 12 is connected to the socket component 3, thereby realizing the connection between the motor 2 and the socket component 3. Such a connection structure is simple, efficient, and easy to operate.

[0060] It can be understood that the shape of the arc-shaped mounting portion 16 is adapted to the outer surface of the motor 2 , so as to facilitate the fitting of the arc-shaped mounting portion 16 and the motor 2 .

[0061] In the above embodiment, if Figure 1 As shown, there are three guide posts 14, so that the number of guide posts 14 is relatively moderate, so that the installation stability between the wire package and the wiring seat 1 can be ensured while avoiding the structure of the wiring seat 1 being too complicated.

[0062] In the above embodiment, there are at least three guide posts, such as Figure 1 , Figure 2 and Figure 4 As shown, the three guide posts 14 include a first guide post, and a second guide post and a third guide post are respectively arranged on both sides of the first guide post, and the second guide post and the third guide post extend obliquely from one end of the base body toward the direction close to the first guide post 14.

[0063] In this embodiment, at least a plurality of guide posts 14 are not arranged completely in parallel, wherein the first guide post, i.e., the middle guide post, is arranged along the radial direction of the stator, while the second guide post and the third guide post on both sides of the first guide post are not arranged parallel to the first guide post, but are arranged closer to the free end in a direction closer to the first guide post (e.g., Figure 2 This arrangement allows the second guide post and the third guide post to be arranged close to the first guide post, so that after the three guide posts 14 are inserted into the wire package, a clamping structure can be formed by the first guide post and the second guide post, as well as the first guide post and the third guide post to clamp the wire package, thereby improving the bonding force between the wiring dome and the wire package and ensuring the installation stability between the two.

[0064] In the above embodiment, if Figure 2 As shown, first protrusions 160 are provided at both ends of the arc-shaped mounting portion 16 along the circumferential direction of the motor 2 , and the first protrusions 160 extend toward the direction close to the wiring portion 12 .

[0065] In this embodiment, in order to prevent the wires wound on the arc-shaped mounting portion 16 from slipping off the arc-shaped mounting portion 16, a first protrusion 160 is provided at both ends of the arc-shaped mounting portion 16. The first protrusion 160 can limit the wires on the arc-shaped mounting portion 16 on the arc-shaped mounting portion 16, so that the position of the wire package can be accurately defined, and the wire package can be prevented from falling off the arc-shaped mounting portion 16, resulting in a connection failure between the arc-shaped mounting portion 16 and the motor 2, thereby improving the reliability and stability of the connection between the arc-shaped mounting portion 16 and the motor 2.

[0066] In the above embodiment, if Figure 2 As shown, a plurality of second protrusions 162 are provided at intervals on one side of the arc-shaped mounting portion 16 close to the wiring portion 12 ; the extension height of the second protrusions 162 in the direction close to the wiring portion 12 is lower than the extension height of the first protrusions 160 in the direction close to the wiring portion 12 .

[0067] In this embodiment, a plurality of spaced second protrusions 162 are provided on one side of the arc-shaped mounting portion 16 close to the wiring portion 12, so that the wire package of the motor 2 can be limited when it is wound onto the arc-shaped mounting portion 16, so that the wires on the arc-shaped mounting portion 16 are evenly dispersed, and the wire packages on the arc-shaped mounting portion 16 are prevented from gathering together, thereby improving the uniformity of force on the arc-shaped mounting portion 16.

[0068] In the above embodiment, if Figure 2 As shown, the terminal block 1 further includes: a positioning block 18, which is arranged on the seat body 10, and is spaced apart from the arc-shaped mounting portion 16 along the axial direction of the motor 2, and extends in a direction away from the terminal portion 12, and at least two guide columns 14 are arranged on a side of the positioning block 18 away from the terminal portion 12. Figure 3 and Figure 4 As shown, the end surface of the positioning block 18 away from the arc-shaped mounting portion 16 and the end surface of the guide column 14 away from the arc-shaped mounting portion 16 are flush with each other. Figure 5 and Figure 6 As shown, at least a portion of the end surface of the positioning block 18 disposed close to the stator core abuts against the end surface of the stator core (such as the first end surface 22).

[0069] In this embodiment, the positioning block 18 can be axially abutted against the motor 2, so that the axial positioning of the terminal block 1 is convenient when the motor 2 and the terminal block 1 are connected, which is conducive to improving the installation stability of the terminal block 1 and avoiding the terminal block 1 from being offset. The guide column 14 is arranged on the positioning block 18, so that the connection between the guide column 14 and the seat body 10 can be realized, and the positioning block 18 can shorten the length of the guide column 14 to avoid the situation that the guide column 14 is too long and the strength of the guide column 14 is insufficient. The end face of the positioning block 18 away from the arc-shaped mounting portion 16 and the end face of the guide column 14 away from the arc-shaped mounting portion 16 are flush with each other, that is, the positioning block 18 and the bottom wall surface of the guide column 14 are flush, so that a larger abutment surface can be formed for abutting and positioning with an end face of the motor 2, so that the bottom support surface of the terminal block 1 can be increased, thereby improving the installation stability of the terminal block 1, so that the terminal block 1 is less likely to tilt.

[0070] In the above embodiment, if Figure 5 As shown, the arc-shaped mounting portion 16 is flush with the end surface of the seat body 10 near the top of the motor 2. This arrangement can make the upper end surface of the terminal block 1 form a plane, thereby improving the aesthetics of the product and reducing the overall height of the product.

[0071] In the above embodiment, if Figure 2 and Figure 4 As shown, the arc-shaped mounting portion 16 extends to both sides of the seat body 10 , and the two arc-shaped mounting portions 16 are symmetrically arranged with respect to the seat body 10 .

[0072] In this embodiment, the arc-shaped mounting portion 16 is arranged to extend toward both sides of the seat body 10, so that the position of the seat body 10 is approximately located in the middle of the arc-shaped mounting portion 16. When the terminal socket 1 and the motor 2 are connected, the portions of the arc-shaped mounting portion 16 extending toward both sides of the seat body 10 can be wrapped with the wire package, so that both sides of the arc-shaped mounting portion 16 are wrapped around the motor 2, and the arc-shaped mounting portion 16 and the terminal socket 1 are subjected to force more evenly, avoiding unstable connection caused by bias to one side, thereby improving the stability and reliability of the connection between the motor 2 and the terminal socket 1.

[0073] In any of the above embodiments, if Figure 4 and Figure 7 As shown, the wiring portion 12 includes: a mounting hole 120 and a mounting groove 122 that are interconnected, and the mounting groove 122 is used to guide the lead wire 32 on the socket component 3 into the mounting hole 120.

[0074] In this embodiment, by providing the mounting hole 120 and the mounting groove 122, it is convenient to provide guidance and installation positioning for the lead wire 32 on the socket component 3, ensuring the convenience and efficiency of the connection between the lead wire 32 and the wiring seat 1. Figure 6 and Figure 7As shown, the lead wire 32 passes through the mounting groove 122 and is inserted into the mounting hole 120 .

[0075] The extending direction of the mounting groove 122 is not parallel to the axial direction of the mounting hole 120 , and generally forms an angle of about 90°. The lead wire 32 includes a bent section that can be inserted into the mounting hole 120 .

[0076] In any of the above embodiments, if Figure 6 As shown, the motor 2 has a stator core, and the positioning block 18 of the terminal block 1 rests on the core surface of the stator core, so that the arc-shaped mounting portion 16 of the terminal block 1 fits or rests against the motor 2 from multiple angles, thereby improving the stability and reliability of the connection between the terminal block 1 and the motor 2.

[0077] like Figure 5 , Figure 6 and Figure 7 As shown, the socket component includes a socket 30 and a lead 32, one end of the lead 32 is connected to the socket 30, and the other end of the lead 32 extends into the mounting hole 120 on the terminal block 1 along the mounting groove 122 on the terminal block 1 to achieve the connection between the socket component 3 and the terminal block 1, and then achieve the connection between the socket component 3 and the motor 2.
