Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of motors, and in particular relates to an outlet wire structure and a motor. Background Art
[0002] With the energy efficiency upgrades of various home appliances, the market for high-efficiency brushless DC motors is growing rapidly. When the controller of a brushless DC motor is integrated into the motor, the waterproofing requirements for the motor become even higher. Traditional elastic outlet nozzles rely on the inherent elasticity of the rubber to maintain contact with the end cap, without external locking force, resulting in limited waterproofing capabilities. To improve motor quality, highly waterproof home appliance motors are becoming increasingly popular in the market. To achieve good waterproofing, waterproof connectors are used for motor lead wires. Conventional waterproof connectors are separate components that are screwed into the outer wall hole of an end cap. This complex structure requires two seals: 1) an elastic seal between the waterproof connector and the end cap; and 2) an elastic seal between the waterproof connector and the power cord.
[0003] When a motor has its own controller, one end of the motor's power cord is connected to the controller, and the other end is terminated and inserted into a connector. Due to the large size of the connector, the waterproof connector cannot pass through. Currently, there are two methods: 1. First, connect the power cord to the connector, then insert the waterproof connector, and then solder it to the controller. However, the waterproof connector on the power cord makes automated wave soldering difficult, requiring manual soldering, which is inefficient. 2. First, solder the power cord to the controller, then insert the waterproof connector, and then terminate it and insert it into the connector. However, this termination process can easily generate static electricity, which can damage the controller. Summary of the Invention

DETAILED DESCRIPTION
[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0021] For ease of description, spatially relative terms such as "on," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" the other devices or features would then be positioned "below" or "beneath" the other devices or features.
[0022] See also Figures 1 to 16 As shown, according to an embodiment of the present invention, there is provided a wire outlet structure, which includes a shell 1 and a connector assembly 2; the shell 1 is provided with a mounting through hole 101, and the connector assembly 2 is provided at the mounting through hole 101; the connector assembly 2 includes a fixing ring 201 and a sleeve 202, the fixing ring 201 is installed on the outer wall of the shell 1, and the fixing ring 201 is provided with a wire outlet through hole 211; a lead wire 3 is passed through the sleeve 202, and the sleeve 202 is embedded in the wire outlet through hole 211, and the fixing ring 201 squeezes the sleeve 202 under the action of external force to deform so that the sleeve 202 covers the lead wire 3.
[0023] Specifically, the lead wire 3 of the motor is passed through the mounting through hole 101 of the housing 1 from the inside of the motor and pulled to the outside of the housing 1. The collar 202 is embedded in the lead wire through hole 211 of the fixing ring 201, and the outer wall of the collar 202 contacts the inner wall of the lead wire through hole 211 of the fixing ring 201. A radially inward external force is applied to the fixing ring 201 that has been fixed on the housing 1. This external force can be a radial pressure applied by a special tool or component, so that the fixing ring 201 is tightened inward in the radial direction. As the fixing ring 201 is tightened, the diameter of its lead wire through hole 211 gradually decreases, thereby squeezing the collar 202 and causing the collar 202 to deform. During the deformation process of the collar 202, the inner wall of the collar 202 will fit tightly against the outer wall of the lead wire 3, thereby achieving a tight covering of the lead wire 3 by the collar 202.
[0024] In this embodiment, the retaining ring 201 is mounted on the outer wall of the housing 1. When tightened radially inward by an external force, it squeezes the collar 202, causing it to deform, thereby causing the collar 202 to tightly wrap around the lead wire 3, thereby forming a good seal between the lead wire 3 and the retaining ring 201. This effectively prevents external impurities such as water and dust from entering the motor through this point, improving the water and dustproof performance of the motor and ensuring the normal operation and service life of the motor's internal components. The retaining ring 201 provides a stable mounting position for the collar 202, firmly embedding the collar 202 in the lead wire through hole 211 of the retaining ring 201, preventing the collar 202 from loosening or displacement due to external forces such as vibration during motor operation and pulling of the lead wire 3. This ensures that the collar 202 and the lead wire 3 always remain tightly wrapped, maintaining a good sealing effect. At the same time, it also ensures the stability of the connection between the lead wire 3 and the internal controller and other components of the motor, avoiding problems such as poor electrical connection caused by loose lead wire 3. In addition, a structural foundation for applying external force is provided for the installation process, which facilitates applying external force to the fixing ring 201 through tools or equipment to achieve the deformation and sealing effect of the ring 202, making the installation process of the entire outlet structure more convenient and efficient.
[0025] In this embodiment, the fixing ring 201 is installed on the outer wall of the shell 1, and its wire outlet hole 211 provides a channel for the lead wire 3, and the ring 202 is embedded in the wire outlet hole 211. When the fixing ring 201 is radially tightened by an external force, the ring 202 is squeezed and deformed, thereby tightly wrapping the lead wire 3 to form a first layer of seal. At the same time, the connection between the fixing ring 201 and the shell 1 also provides a basic guarantee for the seal, preventing moisture from penetrating from the junction of the fixing ring 201 and the shell 1, forming a second layer of seal, which together enhance the waterproof performance of the motor. During the operation of the motor, it may be affected by vibration, temperature changes, etc. The structure and synergy of the fixed ring 201 and the sleeve ring 202 can adapt to these changes and maintain the sealing effect. The squeezing effect of the fixed ring 201 on the sleeve ring 202 enables the sleeve ring 202 to always keep the lead wire 3 tightly wrapped. Even if the lead wire 3 undergoes a slight displacement under a certain degree of vibration or temperature change, the elastic deformation of the sleeve ring 202 can also be adjusted accordingly, ensuring the reliability of the seal and preventing moisture from penetrating into the motor due to changes in operating conditions. The fixing ring 201 is installed on the outer wall of the shell 1, providing stable support and positioning for the collar 202. The collar 202 is embedded in the wire outlet through hole 211 of the fixing ring 201. The structure of the fixing ring 201 limits the radial and axial movement of the collar 202, ensuring that the collar 202 will not be displaced or loosened due to external force during the operation of the motor, thereby ensuring the continuity and stability of the sealing effect between the lead wire 3 and the collar 202. Through the tight wrapping of the collar 202 on the lead wire 3 and the fixing effect of the fixing ring 201 on the collar 202, the lead wire 3 is firmly fixed at the connection between the inside and outside of the motor, which not only prevents the lead wire 3 from being disconnected from the controller and other components inside the motor due to external force, but also reduces the shaking of the lead wire 3 under the action of vibration, etc., thereby improving the stability of the motor operation and extending the service life of the lead wire 3 and the internal components of the motor. During installation, the lead wire 3 is first threaded through the collar 202, then the collar 202 is installed in the lead-out hole 211 of the retaining ring 201. Finally, an external force is applied to tighten the retaining ring 201. This installation method simplifies the complex sealing and fixing operations into a few steps, making assembly easier for operators and improving production efficiency. Furthermore, due to the rational structural arrangement of the retaining ring 201 and the collar 202, the installation process does not require additional complex tools or equipment; only an appropriate external force is required to complete the installation, thus reducing production costs.
[0026] See also Figures 1 to 15 As shown, the fixing ring 201 protrudes from the outer wall of the shell 1 , and the joint assembly 2 further includes an outer ring 203 , which is sleeved on the outer peripheral wall of the fixing ring 201 to apply a circumferential wrapping force to the fixing ring 201 .
[0027] Specifically, one end of the lead-out wire 3 is passed through the opening at one end of the ring 202, through the interior of the ring 202, and the other end of the lead-out wire 3 is extended from the opening at the other end of the ring 202, completing the insertion of the lead-out wire 3 in the ring 202, aligning the ring 202 with the lead-out wire 3 pierced therethrough with the lead-out wire through-hole 211 on the fixing ring 201, and then inserting the ring 202 as a whole into the lead-out wire through-hole 211, so that the outer wall of the ring 202 is tightly fitted with the inner wall of the lead-out wire through-hole 211, completing the installation of the ring 202 in the lead-out wire through-hole 211 of the fixing ring 201. The outer ring 203 is sleeved on the outer circumferential wall of the fixing ring 201, and a circumferential wrapping force is applied to the fixing ring 201, so that the fixing ring 201 is tightened inward in the radial direction. Due to the circumferential wrapping effect of the outer ring 203, the fixing ring 201 is more stable during the tightening process, and the diameter of the lead-out hole 211 is uniformly reduced, thereby squeezing the ring 202 more evenly, causing the ring 202 to deform more evenly, and the inner wall of the ring 202 can fit more tightly and evenly on the outer wall of the lead-out wire 3.
[0028] In this embodiment, the outer ring 203 applies a circumferential wrapping force to the retaining ring 201, causing the retaining ring 201 to tighten inward more evenly when subjected to an external force. This, in turn, causes the collar 202 to be squeezed more evenly. This results in closer contact between the collar 202 and the lead wire 3, reducing gaps and voids, thereby improving the reliability of the seal and effectively preventing impurities such as water and dust from entering the motor through the gap between the lead wire 3 and the retaining ring 201. During motor operation, the collar 202 and lead wire 3 may undergo slight deformation or displacement due to factors such as vibration and temperature changes. The circumferential wrapping of the outer ring 203 on the retaining ring 201 can compensate for these deformations to a certain extent, maintaining the squeeze of the retaining ring 201 against the collar 202, ensuring the durability of the seal, and preventing seal failure due to differential deformation. The outer ring 203 is sleeved onto the outer circumferential wall of the fixing ring 201, providing radial and axial positioning for the fixing ring 201, preventing radial or axial movement of the fixing ring 201 due to external forces during motor operation. This helps maintain the stability of the connection between the lead wire 3 and components such as the motor's internal controller, and prevents loosening or poor connection of the lead wire 3 due to displacement of the fixing ring 201. The addition of the outer ring 203 is equivalent to adding a layer of reinforcement to the exterior of the fixing ring 201, thereby improving the mechanical strength of the entire connector assembly 2. When the motor is subjected to harsh operating conditions such as external impact and vibration, the outer ring 203 can jointly withstand external forces with the fixing ring 201, reducing the risk of damage or deformation of the fixing ring 201, thereby better protecting the lead wire 3 and connection points within the motor. This arrangement simplifies the installation process. First, pass the lead wire 3 through the ring 202, then insert the ring 202 into the wire outlet hole 211 of the fixed ring 201, then put on the outer ring 203 and apply external force to the fixed ring 201 to achieve sealing and fixation. The circumferential wrapping force of the outer ring 203 not only helps to tighten the fixed ring 201 stably, but also ensures the sealing between the ring 202 and the lead wire 3 during the installation process, reducing the complex operations and possible errors in the installation steps. By adjusting the size of the circumferential wrapping force applied by the outer ring 203 to the fixed ring 201, the degree of extrusion of the fixed ring 201 on the ring 202 can be conveniently controlled.
[0029] In this embodiment, the fixing ring 201 is mounted on the outer wall of the housing 1, and its outlet hole 211 provides a passage for the lead wire 3. The collar 202 is embedded in the outlet hole 211 to provide a preliminary seal for the lead wire 3. The outer ring 203 is sleeved on the outer peripheral wall of the fixing ring 201, exerting a circumferential wrapping force on the fixing ring 201. When the fixing ring 201 is tightened radially inward, it can squeeze the collar 202 more evenly and stably, so that the collar 202 more tightly wraps the lead wire 3, forming a more reliable and uniform sealing layer. At the same time, the connection between the fixing ring 201 and the housing 1 also provides a basic guarantee for sealing, preventing moisture from penetrating from the junction of the fixing ring 201 and the housing 1, forming a multi-layer sealing structure, which together enhances the waterproof and dustproof performance of the motor. The fixing ring 201 provides stable support and positioning for the sleeve 202, limiting the radial and axial movement of the sleeve 202. The outer ring 203 further enhances the stability of the fixing ring 201, so that the sleeve 202 will not be displaced or loosened due to external forces during the operation of the motor, ensuring that the sleeve 202 and the lead wire 3 are always tightly wrapped to maintain a good sealing effect. Through the tight wrapping of the sleeve 202 on the lead wire 3 and the fixing effect of the fixing ring 201 and the outer ring 203 on the sleeve 202, the lead wire 3 is firmly fixed at the connection between the inside and outside of the motor. This not only prevents the lead wire 3 from being disconnected from the controller and other components inside the motor due to external force, but also reduces the shaking of the lead wire 3 under the action of vibration, etc., thereby improving the stability of the motor operation and extending the service life of the lead wire 3 and the internal components of the motor.
[0030] It is worth noting that the outer ring 203 can be made of a material with a certain elasticity and strength, and its inner wall is tightly fitted with the outer wall of the fixing ring 201. The outer ring 203 applies a circumferential wrapping force to the fixing ring 201 through its own elastic deformation or other fixing methods (such as threaded connection, snap connection, etc.).
[0031] See also Figures 1 to 15 As shown, the joint assembly 2 also includes a locking piece 204, which is a screw or bolt. At least one locking piece 204 is provided in the circumferential direction of the outer ring 203, and a connecting hole 231 is provided on the outer peripheral wall of the outer ring 203. In the radial direction of the outer ring 203, one end of the locking piece 204 penetrates the connecting hole 231 and abuts against the outer peripheral wall of the fixing ring 201, and the other end of the locking piece 204 is installed in the connecting hole 231 to apply radial extrusion force to the fixing ring 201.
[0032] Specifically, the outer ring 203 is sleeved onto the outer circumferential wall of the fixing ring 201. At this point, the inner wall of the outer ring 203 is tightly fitted against the outer circumferential wall of the fixing ring 201, exerting a certain circumferential wrapping force. The locking member 204 is then installed in the connecting hole 231 of the outer ring 203, with one end of the locking member passing through the connecting hole 231 of the outer ring 203 and the other end facing the outer circumferential wall of the fixing ring 201. The locking member 204 is then tightened. As the locking member 204 is tightened, one end of the locking member 204 gradually presses inward against the outer circumferential wall of the fixing ring 201, while the other end of the locking member 204 gradually screws into the connecting hole 231. This tightening process, to a certain extent, forces the outer ring 203 to exert a uniform wrapping force on the fixing ring 201 in the circumferential direction and also tightens the fixing ring 201 inward in the radial direction. The radial tightening of the fixing ring 201 further squeezes the collar 202, causing the collar 202 to deform so that its inner wall fits tightly against the outer wall of the lead wire 3, thereby achieving a good sealing effect. The degree of tightening of the locking member 204 can be adjusted according to actual needs to ensure that the sealing effect meets the waterproof and dustproof requirements of the motor.
[0033] In this embodiment, the tightening of the locking member 204 can accurately apply radial extrusion force to the fixing ring 201. By adjusting the tightening degree of the locking member 204, the deformation degree of the fixing ring 201 can be controlled, thereby achieving fine adjustment of the sealing force between the collar 202 and the lead wire 3, which helps to ensure that the sealing effect between the collar 202 and the lead wire 3 meets the waterproof and dustproof requirements of the motor, and effectively prevents external water, dust and other impurities from entering the interior of the motor. During the tightening process, the locking member 204 forces the fixing ring 201 to be tightened inward evenly through the outer ring 203, so that the collar 202 is evenly squeezed. This uniform squeezing can ensure that the contact between the collar 202 and the lead wire 3 is closer and more uniform, avoids the problem of uneven sealing caused by excessive or insufficient local pressure, and improves the reliability and stability of the seal. One end of the locking member 204 abuts the outer circumferential wall of the retaining ring 201, and the other end is installed in the connecting hole 231. This structural arrangement restricts the outer ring 203 in both the circumferential and radial directions, preventing the outer ring 203 from loosening or displacement due to factors such as vibration and impact during motor operation, thereby ensuring that the outer ring 203 stably wraps around the retaining ring 201. The installation of the locking member 204 is equivalent to adding a rigid connection between the retaining ring 201 and the outer ring 203, improving the mechanical strength and rigidity of the entire joint assembly 2. This helps to enhance the joint assembly 2's resistance to harsh operating conditions such as external impact and vibration, reduces the risk of damage or deformation to the retaining ring 201, outer ring 203, and collar 202, and ensures the stability and reliability of the connection point of the motor lead wire 3. The use of the locking member 204 simplifies and facilitates the installation process. During installation, simply place the outer ring 203 over the fixing ring 201, then screw the locking member 204 into the connecting hole 231 and tighten it to the appropriate degree to complete the installation and sealing of the entire connector assembly 2. This installation method does not require complex tools or equipment, reducing installation difficulty and cost. The locking member 204 provides flexible adjustment capabilities, allowing the locking degree to be adjusted at any time according to actual needs. If the sealing effect is found to be unsatisfactory during installation, the sealing force can be enhanced by further tightening the locking member 204. Conversely, if the sealing force is too strong and causes damage to the lead wire 3 or the ring 202, the locking member 204 can be loosened and adjusted appropriately to ensure the optimal sealing state.
[0034] In this embodiment, the outer ring 203 applies a circumferential wrapping force to the fixing ring 201, constraining the fixing ring 201 in the circumferential direction. Simultaneously, the locking member 204 applies a radial extrusion force to the fixing ring 201, tightening the fixing ring 201 inward in the radial direction. The forces in these two directions cooperate with each other to enable the fixing ring 201 to more stably and evenly squeeze the collar 202, thereby achieving closer contact between the collar 202 and the lead wire 3, thereby significantly improving the sealing effect and effectively preventing impurities such as moisture and dust from entering the interior of the motor through the gap between the lead wire 3 and the fixing ring 201. The circumferential wrapping force of the outer ring 203 can initially constrain the shape of the fixing ring 201, while the radial extrusion force of the locking member 204 can further adjust the degree of deformation of the fixing ring 201. In actual application, the forces between the outer ring 203 and the locking member 204 can be flexibly adjusted according to the waterproof and dustproof requirements of the motor and the characteristics of the lead wire 3 to achieve the best sealing effect. The outer ring 203 limits the circumferential displacement of the fixing ring 201 through circumferential wrapping force, and the locking piece 204 limits the radial displacement of the fixing ring 201 through radial extrusion force. The two work together to make the position of the fixing ring 201 in space more stable, reducing the possibility of the fixing ring 201 loosening or deformation due to vibration, impact and other factors during the operation of the motor, thereby improving the fixing stability of the entire connector assembly 2 and ensuring the reliability of the connection between the lead wire 3 and components such as the internal controller of the motor. The outer ring 203 and the locking piece 204 strengthen the fixing ring 201 circumferentially and radially respectively, so that the structural strength of the fixing ring 201 is significantly improved. This multi-dimensional reinforcement method enables the connector assembly 2 to better withstand the influence of external mechanical stress and environmental factors, reduces the risk of damage to the fixing ring 201, the ring 202 and the lead wire 3, and extends the service life of the motor. During the installation process, the outer ring 203 is first placed on the fixing ring 201 and a certain circumferential wrapping force is applied, which can preliminarily position and fix the fixing ring 201, providing a stable foundation for the subsequent installation of the locking member 204. Then, by installing and tightening the locking member 204, the fixing effect and sealing performance of the fixing ring 201 are further enhanced. This installation sequence is reasonable and efficient, which is convenient for operators to perform installation operations and also ensures the installation quality. The synergistic effect of the outer ring 203 and the locking member 204 makes the installed joint assembly 2 have a certain degree of adjustability. If it is found that the sealing effect is not ideal or the position of the fixing ring 201 needs to be fine-tuned during the installation process, it can be achieved by adjusting the circumferential wrapping force of the outer ring 203 or the radial extrusion force of the locking member 204. This flexible adjustment capability helps to ensure that the installation quality of the joint assembly 2 meets the use requirements of the motor.
[0035] As a specific implementation, the fixing ring 201 , the outer ring 203 and the sleeve ring 202 are all annular structures and are nested in sequence.
[0036] See also Figures 1 to 15 As shown, at least one adjustment groove 212 is provided along the circumference of the fixing ring 201. In the radial direction of the fixing ring 201, one end of the adjustment groove 212 extends to the outer edge of the fixing ring 201, and the other end of the adjustment groove 212 extends to the wire outlet through hole 211. The fixing ring 201 is squeezed and narrowed by external force. The depth and width of the adjustment groove 212 are flexibly set according to specific sealing requirements.
[0037] Specifically, align the ferrule 202 with the lead wire 3 with the lead wire through hole 211 on the fixed ring 201, and then insert the ferrule 202 as a whole into the lead wire through hole 211, so that the outer wall of the ferrule 202 fits tightly with the inner wall of the lead wire through hole 211, and complete the installation of the ferrule 202 in the lead wire through hole 211 of the fixed ring 201. Put the outer ring 203 on the outer peripheral wall of the fixed ring 201, and the inner wall of the outer ring 203 fits tightly with the outer peripheral wall of the fixed ring 201. At this time, the outer ring 203 applies a certain circumferential wrapping force to the fixed ring 201. The locking piece 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking piece 204 passes through the connecting hole 231 on the outer ring 203, and the other end faces the outer peripheral wall of the fixing ring 201. The locking piece 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking piece 204 passes through the connecting hole 231 on the outer ring 203, and the other end faces the outer peripheral wall of the fixing ring 201. The tightening of the locking piece 204 causes the outer ring 203 to apply a more uniform wrapping force to the fixing ring 201 in the circumferential direction. At the same time, the radial extrusion force of the locking piece 204 is transmitted to the fixing ring 201 through the outer ring 203, so that the fixing ring 201 is tightened inward in the radial direction. The adjustment groove 212 on the fixing ring 201 is narrowed when subjected to external force, so that the fixing ring 201 can deform more flexibly, thereby squeezing the ring 202 more evenly, causing the ring 202 to deform so that its inner wall fits tightly against the outer wall of the lead-out wire 3, achieving a good sealing effect.
[0038] In this embodiment, the provision of the adjustment groove 212 enables the fixing ring 201 to deform more flexibly when subjected to external force. The external force is transmitted to the fixing ring 201 through the outer ring 203 and the locking member 204. When the fixing ring 201 is tightened inwardly in the radial direction, the presence of the adjustment groove 212 allows a local area of the fixing ring 201 to bend and narrow more easily. The flexibility of this local deformation helps the fixing ring 201 to squeeze the collar 202 more evenly, making the contact between the collar 202 and the lead wire 3 closer, thereby significantly improving the sealing effect. The provision of the adjustment groove 212 enables the fixing ring 201 to transmit pressure to the collar 202 more evenly when subjected to force. Due to the presence of the adjustment groove 212, the pressure can be more evenly distributed around the collar 202 during the inward tightening process of the fixing ring 201, avoiding the problem of inconsistent sealing caused by uneven deformation of the fixing ring 201, and ensuring that the sealing effect between the collar 202 and the lead wire 3 is uniform and reliable. The presence of the adjustment groove 212 enables the fixing ring 201 to better adapt to lead wires 3 of different diameters or shapes. When the size of the lead wire 3 changes, the fixing ring 201 can flexibly adjust the degree of squeezing on the ring 202 by adjusting the narrowing degree of the groove 212, thereby ensuring that the sealing effect is not affected by the size difference of the lead wire 3. This improves the versatility and adaptability of the entire connector assembly 2, making it applicable to a variety of motor settings and lead wires 3 of different specifications. During the operation of the motor, it may be affected by complex working conditions such as vibration and temperature changes, resulting in slight changes in the relative position or deformation between the lead wire 3 and the fixing ring 201. The setting of the adjustment groove 212 enables the fixing ring 201 to respond quickly to these changes. Through local deformation adjustment, it always maintains good contact and sealing effect with the ring 202, ensuring reliable operation of the motor under various working conditions.
[0039] It is worth noting that the fixing ring 201 of this embodiment has two different structural forms, which are suitable for two different housing 1 structures. Specifically, the housing 1 structure is a split end cover and an integral motor housing 13. The end cover is a stretched end cover structure, and the motor housing 13 is a rolled plate housing structure. Two corresponding fixing ring 201 structures are provided for these two structures. Specific implementation methods are as follows: See also Figures 1 to 8 As shown, as the first type of fixing ring 201 structure, the fixing ring 201 includes a first fixing plate 21 and a second fixing plate 22. The first fixing plate 21 and the second fixing plate 22 are semi-annular, and the opening sides of the first fixing plate 21 and the second fixing plate 22 are arranged opposite to each other. A wire outlet through hole 211 is formed between the inner walls of the first fixing plate 21 and the second fixing plate 22. There is a gap between the opening sides of the first fixing plate 21 and the second fixing plate 22, and the gap forms an adjustment groove 212.
[0040] Specifically, align the ring 202 with the lead wire 3 pierced therethrough with the lead wire through hole 211 on the fixing ring 201. The lead wire through hole 211 is formed by the inner walls of the first fixing plate 21 and the second fixing plate 22. Insert the ring 202 into the lead wire through hole 211 to ensure that the outer wall of the ring 202 fits tightly with the inner wall of the lead wire through hole 211. This completes the installation of the ring 202 in the lead wire through hole 211 of the fixing ring 201. The tightening of the locking member 204 causes the outer ring 203 to apply a more uniform wrapping force to the first fixing plate 21 and the second fixing plate 22 in the circumferential direction. At the same time, the radial extrusion force of the locking member 204 is transmitted to the first fixing plate 21 and the second fixing plate 22 through the outer ring 203, so that the first fixing plate 21 and the second fixing plate 22 are tightened inward in the radial direction. The gap between the first fixing plate 21 and the second fixing plate 22, that is, the adjustment groove 212, is narrowed when subjected to external force, so that the fixing ring 201 can be deformed more flexibly, thereby squeezing the ring 202 more evenly.
[0041] In this embodiment, this segmented arrangement enables the fixing ring 201 to deform more flexibly when subjected to external force. The gap (adjustment groove 212) between the first fixing plate 21 and the second fixing plate 22 allows the fixing ring 201 to be tightened inward more easily in the radial direction, thereby more evenly squeezing the ring 202. This uniform squeezing makes the contact between the ring 202 and the lead wire 3 closer, thereby improving the sealing effect. The presence of the adjustment groove 212 enables the fixing ring 201 to distribute pressure more evenly when subjected to force. When the outer ring 203 and the locking member 204 apply external force, the two semi-annular parts of the fixing ring 201 can bend inward evenly, ensuring that the ring 202 is evenly squeezed and avoiding sealing problems caused by uneven pressure. This structure can better adapt to lead wires 3 of different diameters or shapes. By adjusting the gap between the first fixing plate 21 and the second fixing plate 22, it can adapt to lead wires 3 of different sizes to a certain extent, ensuring the sealing effect between the ring 202 and the lead wire 3. During the operation of the motor, it may be affected by complex working conditions such as vibration and temperature changes. This segmented setting enables the fixing ring 201 to respond to these changes more flexibly. By adjusting the narrowing or expansion of the groove 212, it maintains good contact with the ring 202 to ensure the durability of the sealing effect.
[0042] See also Figures 1 to 8 As shown, when the shell 1 is an end cover, the end cover includes a first cover body 11 and a second cover body 12 connected to each other, and the connection between the first cover body 11 and the second cover body 12 is respectively provided with a first through hole and a second through hole, and the inner walls of the first through hole and the second through hole form a mounting through hole 101; the first fixing plate 21 is arranged at the first through hole, and the first fixing plate 21 is integrally formed with the first cover body 11, and the second fixing plate 22 is arranged at the second through hole, and the second fixing plate 22 is integrally formed with the second cover body 12.
[0043] Specifically, the first cover body 11 is the upper end cover, and the second cover body 12 is the lower end cover. The ring 202 with the lead wire 3 is placed on the second fixing plate 22 of the second end cover, and the first cover body 11 is installed on the second cover body 12, ensuring that the first through hole and the second through hole are aligned to form a complete installation through hole 101. The first fixing plate 21 and the second fixing plate 22 form a complete fixing ring 201, and the first cover body 11 and the second cover body 12 are fixed together by bolts, screws or other suitable connection methods. At this time, the ring 202 is embedded in the lead wire through hole 211.
[0044] In this embodiment, the split end cover is composed of a first cover body 11 and a second cover body 12, which respectively have a first through hole and a second through hole at the connection to form a complete installation through hole 101. The first fixing plate 21 and the second fixing plate 22 are respectively arranged at the first through hole and the second through hole. This arrangement allows the two fixing plates 23 to be adjusted and fixed separately during the installation process to ensure the sealing between the ring 202 and the lead wire 3. The first fixing plate 21 and the second fixing plate 22 cooperate with the ring 202 to form a multi-layer sealing structure. After the ring 202 is inserted into the first through hole and the second through hole, it fits tightly with the inner walls of the first fixing plate 21 and the second fixing plate 22 respectively, thereby increasing the reliability and redundancy of the seal and effectively preventing moisture and dust from entering the interior of the motor from the end cover connection or around the lead wire 3. The first cover body 11 and the second cover body 12 are connected to form the overall structure of the end cover, and the first fixing plate 21 and the second fixing plate 22 are respectively installed at their respective through holes. This layout disperses the force of the fixing ring 201 structure to avoid stress concentration, and the external force is evenly transmitted to the fixing plate 23, thereby improving its stability and ensuring that the fixing ring 201 is not easily deformed or displaced when the motor is running, and maintains a good seal and fixation with the ring 202 and the lead wire 3. The first fixing plate 21 and the second fixing plate 22 are semi-annular, and the open sides are opposite to each other to form a wire outlet through hole 211, which can adapt to lead wires 3 of different diameters. By adjusting the tightening degree of the locking piece 204, the tightening degree of the fixing ring 201 is changed, so as to achieve reliable fixation and sealing of lead wires 3 of different sizes, thereby improving the versatility of the connector assembly 2.
[0045] See also Figures 9 to 15 As shown, as the second type of fixing ring 201 structure, the fixing ring 201 includes a plurality of fan-shaped fixing plates 23, and the plurality of fixing plates 23 are arranged around the same center. The inner walls of the plurality of fixing plates 23 form wire outlet holes 211, and there are gaps between adjacent fixing plates 23, and the gaps form adjustment grooves 212.
[0046] Specifically, the collar 202, through which the lead wire 3 is threaded, is aligned with the lead wire through-hole 211 of the fixing ring 201. This through-hole is formed by the inner walls of multiple fixing plates 23. The locking member 204 is installed in the connecting hole 231 of the outer ring 203. One end of the locking member 204 passes through the connecting hole 231 of the outer ring 203, and the other end faces the outer peripheral wall of the fixing plate 23. The locking member 204 forces the outer ring 203 to apply a circumferential wrapping force to the fixing plate 23, while simultaneously transmitting a radial extrusion force to the fixing plate 23, causing the fixing plate 23 to tighten radially inward. When subjected to external force, the gap between adjacent fixing plates 23 narrows, causing the fixing ring 201 to flexibly deform and evenly squeeze the collar 202. After being squeezed, the collar 202 deforms, and the inner wall of the collar 202 closely fits the outer wall of the lead wire 3, achieving a seal.
[0047] In this embodiment, the inner walls of multiple sector-shaped stators 23 collectively form a lead-out hole 211. When external force is applied by the outer ring 203 and the locking member 204, each stator 23 evenly compresses the collar 202, ensuring closer and more uniform contact between the collar 202 and the lead-out wire 3, significantly improving the sealing effect. The gaps between adjacent stators 23 form adjustment slots 212, allowing each stator 23 to independently undergo local deformation when subjected to external force. This flexibility in local deformation helps the retaining ring 201 better adapt to the shapes of the collar 202 and the lead-out wire 3, further enhancing the sealing performance and effectively preventing moisture and dust from entering the motor interior through the gap between the lead-out wire 3 and the stator ring 201. This structure can better accommodate lead-out wires 3 of varying diameters or shapes. By adjusting the tightening degree of the locking member 204, the tightening degree of the retaining ring 201 can be varied, allowing the multiple stators 23 to work synergistically to reliably secure and seal lead-out wires 3 of varying sizes, thereby enhancing the versatility and adaptability of the connector assembly 2. Although the fixing ring 201 is composed of multiple sector-shaped fixing plates 23, the strength of the entire structure is enhanced through the fixing effect of the outer ring 203 and the locking piece 204. The outer ring 203 and the locking piece 204 work together to enable the fixing ring 201 to remain stable when subjected to external force, reducing the risk of excessive deformation or damage. The arrangement of multiple sector-shaped fixing plates 23 combined with the fixing effect of the outer ring 203 and the locking piece 204 improves the stability of the fixing ring 201. During the operation of the motor, the fixing ring 201 can maintain its shape and position more stably, ensuring that the sealing effect between the ring 202 and the lead wire 3 is not invalidated due to vibration or impact.
[0048] See also Figures 9 to 15 As shown, when the housing 1 is a motor housing 13 , a mounting through hole 101 is provided on the motor housing 13 , and a plurality of fixing plates 23 are provided at the mounting through hole 101 .
[0049] Specifically, the collar 202, which has been penetrated by the lead wire 3, is aligned with the mounting hole 101 on the motor housing 13. The mounting hole 101 is provided with a plurality of fan-shaped fixing plates 23. The inner walls of these fixing plates 23 together form the lead wire hole 211. The collar 202 is inserted into the lead wire hole 211, ensuring that the outer wall of the collar 202 is tightly fitted with the inner wall of the fixing plates 23. After the collar 202 is installed in the lead wire hole 211 of the fixing ring 201, the outer ring 203 is sleeved on the outer circumferential wall of the fixing ring 201. The inner wall of the outer ring 203 is tightly fitted with the outer wall of the fixing plates 23. At this time, the outer ring 203 exerts a certain circumferential wrapping force on the fixing ring 201, but does not cause significant radial deformation of the fixing ring 201. As the locking member 204 is tightened, one end of the outer ring 203 gradually presses inwardly against the outer circumferential wall of the fixing ring 201, while the other end of the locking member 204 is gradually screwed into the connecting hole 231. The tightening of the locking member 204 causes the outer ring 203 to apply a more uniform wrapping force to the fixing ring 201 in the circumferential direction. At the same time, the radial extrusion force of the locking member 204 is transmitted to the fixing ring 201 through the outer ring 203, so that the fixing ring 201 is tightened inward in the radial direction. The gap between adjacent fixing plates 23 (adjustment groove 212) is narrowed when subjected to external force, so that the fixing ring 201 can be deformed more flexibly, thereby squeezing the collar 202 more evenly. The collar 202 is deformed after being squeezed by the fixing ring 201, and its inner wall is tightly fitted to the outer wall of the lead-out wire 3, thereby achieving a good sealing effect.
[0050] In this embodiment, the inner walls of multiple fan-shaped fixing plates 23 jointly form a wire outlet through hole 211. When the outer ring 203 and the locking member 204 apply external force, each fixing plate 23 can evenly squeeze the ring 202, so that the contact between the ring 202 and the lead wire 3 is tighter and more uniform, thereby significantly improving the sealing effect. The gap between adjacent fixing plates 23 forms an adjustment groove 212, so that each fixing plate 23 can independently undergo local deformation when subjected to external force. The flexibility of this local deformation helps the fixing ring 201 to better adapt to the shape of the ring 202 and the lead wire 3, further enhancing the sealing performance, and effectively preventing moisture and dust from entering the interior of the motor through the gap between the lead wire 3 and the fixing ring 201. When inserting the collar 202 into the lead-out hole 211 of the fixing ring 201, the multiple sector-shaped fixing pieces 23 provide greater flexibility, facilitating the insertion of the collar 202. During the subsequent tightening process, the presence of the adjustment slot 212 also makes it easier to adjust the fixing ring 201 to the appropriate position, reducing the difficulty of installation. By adjusting the tightening degree of the locking member 204, the deformation degree of the fixing ring 201 can be finely controlled, thereby optimizing the sealing effect. If the sealing effect is found to be unsatisfactory after installation, the sealing effect can be enhanced by further tightening the locking member 204. The arrangement of these multiple sector-shaped fixing pieces 23, combined with the fixing function of the outer ring 203 and the locking member 204, improves the stability of the fixing ring 201. During the operation of the motor, the fixing ring 201 can more stably maintain its shape and position, ensuring that the sealing effect between the collar 202 and the lead-out wire 3 is not lost due to vibration or impact. The fixing ring 201 is directly set at the mounting hole 101 of the motor housing 13, making the structure of the entire motor more compact, reducing the need for additional end covers or other components, and reducing the total volume and weight of the motor. The fixing ring 201 is tightly combined with the motor housing 13, which not only achieves the sealing of the lead wire 3, but also enhances the overall sealing performance of the motor housing 13. The cooperation of multiple fixing plates 23 with the motor housing 13 makes the sealing at the mounting hole 101 more reliable, preventing external contaminants from entering the interior of the motor from there.
[0051] See also Figures 1 to 16 As shown, the collar 202 is made of elastic material and includes an annular body 221 and a radial flange 222. A lead wire 3 is passed through the annular body 221. One end of the annular body 221 is embedded in the lead wire through hole 211. The other end of the annular body 221 is provided with a radial flange 222. The radial flange 222 extends outward from the outer wall of the annular body 221 and abuts against the inner end surface of the fixing ring 201.
[0052] Specifically, one end of the lead-out wire 3 is inserted from one end of the annular body 221 of the ring 202, passes through the interior of the annular body 221, and the other end of the lead-out wire 3 is extended from the other end of the annular body 221, completing the insertion of the lead-out wire 3 in the ring 202, ensuring that the annular body 221 of the ring 202 can smoothly pass through the wire outlet hole 211 of the fixing ring 201, and the radial flange 222 can abut against the inner end face of the fixing ring 201. Align the annular body 221 of the collar 202 with the outlet hole 211 of the fixing ring 201, and insert the annular body 221 of the collar 202 into the outlet hole 211 until the radial flange 222 abuts against the inner end face of the fixing ring 201, ensuring that the annular body 221 of the collar 202 fits tightly against the inner wall of the outlet hole 211, and sleeve the outer ring 203 on the outer circumferential wall of the fixing ring 201. The inner wall of the outer ring 203 fits tightly against the outer circumferential wall of the fixing ring 201. At this time, the outer ring 203 applies a certain circumferential wrapping force to the fixing ring 201, and the locking piece 204 is installed on the outer ring 203. The outer ring 203 is tightened to fit the fixing ring 201, and the fixing ring 201 is tightened to fit the fixing ring 201. The annular body 221 of the collar 202 is deformed after being squeezed by the fixing ring 201, and its inner wall fits tightly against the outer wall of the lead-out wire 3, thereby achieving a good sealing effect. At the same time, the radial flange 222 abuts against the inner end face of the fixing ring 201, further enhancing the sealing effect and preventing moisture and dust from entering the interior of the motor through the gap between the fixing ring 201 and the collar 202.
[0053] In this embodiment, the inner wall of the annular body 221 fits tightly against the lead wire 3 to form a first layer of seal; the radial flange 222 abuts against the inner end face of the fixing ring 201 to form a second layer of seal. This double sealing structure significantly increases the sealing contact area, effectively preventing moisture and dust from entering the interior of the motor through the gap between the lead wire 3 and the fixing ring 201. The radial flange 222 abuts against the inner end face of the fixing ring 201 to form a physical barrier, which further enhances the sealing effect. Even if the sealing effect of the annular body 221 is slightly reduced for some reason, the radial flange 222 can still play a role in supplementary sealing, thereby improving the reliability of the sealing. A radial flange 222 extends outward from the outer wall of the annular body 221 and abuts the inner end surface of the retaining ring 201. This structure limits the axial movement of the collar 202, ensuring that the collar 202 maintains a stable position during motor operation and preventing axial displacement of the collar 202 due to vibration or tension, thereby ensuring a durable sealing effect. The provision of the radial flange 222 increases the overall structural strength of the collar 202, enabling it to maintain its shape when subjected to radial and axial forces, reducing the possibility of deformation, thereby improving the durability and reliability of the collar 202. The abutment of the radial flange 222 against the inner end surface of the retaining ring 201 provides a clear positioning reference for installation. When installing the collar 202, simply insert the annular body 221 into the wire outlet hole 211 of the retaining ring 201 until the radial flange 222 contacts the inner end surface of the retaining ring 201 to ensure that the collar 202 is properly installed, simplifying the installation operation and improving installation efficiency.
[0054] As a specific embodiment, a first type of fixing ring 201 structure comprises a first fixing plate 21 and a second fixing plate 22, and the housing 1 serves as an end cap. In this case, the outer wall of the outer ring 203 is provided with two connection holes 231 and two locking members 204. Specifically, two locking members 204 are provided in the radial direction of the fixing ring 201, and each of the first fixing plate 21 and the second fixing plate 22 is provided with a corresponding locking member 204. In other embodiments, the installation position and number of the locking members 204 can be adjusted based on the required locking force.
[0055] A motor includes an outgoing wire structure, and the outgoing wire structure is the outgoing wire structure mentioned above.
[0056] In this embodiment, the lead-out structure, through the coordinated action of components such as the retaining ring 201, the sleeve ring 202, and the outer ring 203, reliably seals the lead-out wire 3, effectively preventing external impurities such as water and dust from entering the motor interior. This improves the motor's dust and water resistance and enhances its adaptability and reliability in harsh environments. The excellent sealing performance reduces the probability of damage to internal motor components and short circuits caused by the intrusion of external impurities, thereby extending the motor's service life and reducing maintenance costs. The provision of the sleeve ring 202 and the retaining ring 201 ensures that the lead-out wire 3 is securely fixed at the connection between the motor interior and exterior, reducing the risk of the lead-out wire 3 shaking or loosening during motor operation, improving the stability of the motor's operation, and avoiding motor failures caused by poor contact of the lead-out wire 3. The structure can adapt to vibration and impact during motor operation, maintain reliable sealing and fixation, and ensure stable operation of the motor under various operating conditions. It is particularly suitable for applications requiring high stability.
