The coil assembly typically includes a stator assembly, wires, and a mounting structure. During operation, a gap forms between the wires and the mounting structure. Condensate generated during refrigeration can then enter the coil assembly through this gap, leading to a decrease in electrical performance and, in severe cases, damage to the coil. Utility Model Content

[0004] To address the aforementioned problems, according to one aspect of this utility model, a coil component is provided, comprising a stator assembly, a conductor, and a fixing structure. The stator assembly has a pin and a mounting hole through which a valve body passes. The conductor includes a connecting segment, a sealing segment, and an exposed segment connected in sequence. The connecting segment and the pin are electrically connected, and the connecting segment and / or the sealing segment have at least one bend.

[0005] Furthermore, the bend is located in the connecting section, and at least part of the sealing section has an angle between the extending direction and the extending direction of the fixing structure.

[0006] Furthermore, the sealing section includes a first section and a second section that are connected to each other, with an included angle between the first section and the second section, and a bend formed at the connection between the first section and the second section.

[0007] Furthermore, the included angle of the bend should not exceed 90°.

[0008] Furthermore, the second segment and the exposed segment are connected.

[0009] Furthermore, the connecting segment is connected to the first segment.

[0010] Furthermore, before the coil component is assembled to the client, the extension direction of the second segment is the same as that of the exposed segment.

[0011] Furthermore, after the coil component is assembled to the client, there is an angle between the extension direction of the second segment and the extension direction of the exposed segment.

[0012] Furthermore, the second segment is connected to the exposed segment, and there is an angle between the extension direction of the second segment and the extension direction of the fixed structure.

[0013] Alternatively, the sealing section comprises multiple line segments connected in sequence, with an included angle between each pair of adjacent line segments and a bend formed at the connection point of each pair of adjacent line segments.

[0014] Furthermore, the mounting hole opening faces downwards, and the wire extends from the end of the fixing structure away from the stator assembly; the end of the fixing structure away from the stator assembly faces directly upwards or diagonally upwards, or the end of the fixing structure away from the stator assembly faces directly downwards or diagonally downwards.

[0015] Furthermore, the sealing section has at least one bend; the stator assembly includes a stator housing and a frame, the stator housing having a receiving cavity and a passage, a portion of the frame being located within the receiving cavity, and another portion of the frame extending out of the receiving cavity from the passage; a pin is mounted on the frame; the bend is located above the passage or below the passage.

[0016] Furthermore, the sealing section includes a first section and a second section that are connected to each other, with an included angle between the first section and the second section, and a bend formed at the connection between the first section and the second section.

[0017] Alternatively, the outer circumferential surface of the sealing section has annular ribs, and the fixing structure covers the annular ribs.

[0018] Furthermore, the conductor includes multiple leads, each lead being covered with an insulating layer on its outer periphery; the conductor also includes an insulating sheath covering a sealed section and an exposed section, with the connecting section located outside the insulating sheath.

[0019] Furthermore, the connection positions of the fixed structure covering the connecting section and the pin are fixed by injection molding.

[0020] Alternatively, the coil assembly may also include a connecting block and an insulating cover. The connecting block covers a portion of the pin, and the insulating cover has an injection cavity. The connecting block is located within the injection cavity, and the cavity is filled with a sealing material. The sealing material seals the connection point between the pin and the wire, and forms a fixed structure.

[0024] In this design, the conductor includes a connecting section, a sealing section, and an exposed section. This allows the pins on the stator assembly to easily connect electrically to the connecting section of the conductor, simplifying the overall assembly process, reducing installation difficulty, and preventing loosening or poor contact of the conductor during use.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 5 As shown, an embodiment of the present invention provides a coil component, including a stator assembly 100, a conductor 500, and a fixing structure 600. The stator assembly 100 has a pin and a mounting hole 101 for a valve body to pass through. The conductor 500 includes a connecting section 510, a sealing section 550, and an exposed section 540. The connecting section 510 is electrically connected to the pin, and the connecting section 510 and / or the sealing section 550 has at least one bend. The fixing structure 600 is connected to the stator assembly 100, and the fixing structure 600 covers the connecting section 510 and the sealing section 550, while the exposed section 540 is located outside the fixing structure 600.

[0035] In this design, the conductor 500 includes a connecting section 510, a first section 520, a second section 530, and an exposed section 540. This allows the pins on the stator assembly 100 to easily connect electrically with the connecting section 510 of the conductor 500, simplifying the overall assembly process, reducing installation difficulty, and preventing the conductor 500 from becoming loose or experiencing poor contact during use. By providing at least one bend in at least one of the connecting section 510 and the sealing section 550, the path of water entering the coil component through the gap formed between the conductor 500 and the fixing structure 600 is lengthened, increasing the time it takes for water to enter the coil component and improving its waterproof performance. Furthermore, by covering the connecting section 510 and the sealing section 550 of the conductor 500 with the fixing structure 600, these parts of the conductor 500 are protected from external damage, ensuring the long-term reliable operation of the conductor 500. The exposed section 540 of the conductor 500 is located outside the fixed structure 600, which allows for easy connection with other electrical components, reducing unnecessary external contact and thus improving safety and reducing the risk of potential electrical faults.

[0036] In some embodiments, the bend is located at the connecting section 510, and at least a portion of the extending direction of the sealing section 550 forms an angle with the extending direction of the fixing structure 600. In this arrangement, because of the angle between the extending directions of the sealing section 550 and the fixing structure 600, compared to an arrangement where the extending directions of the sealing section 550 and the fixing structure 600 are parallel, the length of the sealing section 550 is increased, thereby increasing the path length and time for water to enter the coil component. The extending direction of the fixing structure 600 is the direction of its overall length.

[0037] In some embodiments, the sealing segment 550 includes a first segment 520 and a second segment 530 connected to each other, with an included angle between the first segment 520 and the second segment 530, and a bend forming at the connection between the first segment 520 and the second segment 530. That is, the sealing segment 550 is configured to include at least two structural segments, with a bend forming at the connection between the two structural segments. This increases the length of the sealing segment 550 within the fixed structure 600 compared to a non-bendable design, thereby increasing the difficulty for water to enter the coil component.

[0038] The axis of the first segment 520 may be parallel or not parallel to the axis of the mounting hole 101. The axis of the second segment 530 may be parallel or not parallel to the axis of the mounting hole 101.

[0039] In some embodiments, the connecting segment 510, the first segment 520, the second segment 530, and the exposed segment 540 are connected sequentially. Alternatively, in some embodiments, the second segment 530 and the exposed segment 540 are connected by other cables; in some embodiments, the connecting segment 510 and the first segment 520 are connected by other cables.

[0040] Furthermore, the angle between the first segment 520 and the second segment 530 should not exceed 90°. If the angle is greater than 90°, the bend at the connection between the first segment 520 and the second segment 530 of the conductor 500 will be larger, increasing production costs and increasing the risk of breakage, thus posing some safety risks in use. Limiting the angle between the first segment 520 and the second segment 530 to within 90° allows for a more compact layout of the conductor 500, preventing it from occupying too much space and improving overall space utilization. Additionally, the conductor 500 and the coil components often generate heat during operation. By controlling the angle to within 90°, the layout of the conductor 500 can be better controlled, resulting in more even heat dissipation. This prevents excessive bending of the conductor 500, which could cause heat to accumulate in a certain area, thus improving thermal management efficiency and extending the lifespan of the components.

[0041] In some embodiments, the second segment 530 and the exposed segment 540 are connected, and the connecting segment 510 and the first segment 520 are connected. Before the coil component is assembled to the client, the extending direction of the second segment 530 is the same as the extending direction of the exposed segment 540. After the coil component is assembled to the client, there is an angle between the extending direction of the second segment 530 and the extending direction of the exposed segment 540.

[0042] In actual installation, bending the extension direction of the exposed section 540 at an angle relative to the extension direction of the second section 530 facilitates the connection of the exposed section 540 with other electrical components. Furthermore, the bend formed at the connection between the exposed section 540 and the second section 530 reduces the likelihood of gaps forming at the junction of the conductor 500 and the encapsulation layer 420 during temperature changes, and also reduces the peel strength between the conductor 500 and the encapsulation layer 420, thereby improving waterproof performance. The electrical components can be power supplies, etc.

[0043] In some embodiments, the second segment 530 and the exposed segment 540 are connected, and there is an angle between the extending direction of the second segment 530 and the extending direction of the fixed structure 600. This increases the length of the sealing segment 550, allowing water to travel a longer distance through the gap formed between the wire 500 and the fixed structure 600 to enter the coil component. This increases the time it takes for water to enter the coil component, improving the waterproof performance of the coil component. The second segment 530 is the final exit segment of the sealing segment 550.

[0044] In some embodiments, the sealing section 550 includes a plurality of sequentially connected line segments, each pair of adjacent line segments having an included angle, and each connection point of two adjacent line segments forming a bend. Because the sealing section 550 has multiple bends, its length is further increased, making it more difficult for water to enter the coil component and improving the waterproofing effect.

[0045] In this design, the mounting hole 101 faces downwards, and the wire 500 extends from the end of the fixing structure 600 away from the stator assembly 100. This end of the fixing structure 600 away from the stator assembly 100 may face directly upwards or diagonally upwards, or directly downwards or diagonally downwards. The orientation of this end is designed according to actual installation needs to facilitate wiring.

[0046] The extension direction of the fixed structure 600 may be the same as or different from the extension direction of the first segment 520. The extension direction of the fixed structure 600 may be the same as or different from the extension direction of the second segment 530. As long as there is an angle between the first segment 520 and the second segment 530, it is acceptable. The extension direction of the fixed structure 600 refers to the extension direction of the overall length of the fixed structure 600.

[0047] like Figures 1 to 4 As shown, the sealing section 550 has at least one bend; the stator assembly 100 includes a stator housing 110 and a frame 120, the stator housing 110 having a receiving cavity and a passage 112, a portion of the frame 120 being located within the receiving cavity, and another portion of the frame 120 extending out of the receiving cavity from the passage 112; a pin is mounted on the frame 120; the bend is located above or below the passage 112. The sealing section 550 includes a first section 520 and a second section 530 interconnected, with an included angle between the first section 520 and the second section 530, and a bend forming at the connection between the first section 520 and the second section 530. A fixing structure 600 covers the portion of the frame 120 located outside the receiving cavity, and the fixing structure 600 also covers the portion of the pin located outside the frame 120.

[0048] In some embodiments, the receiving cavity of the stator housing 110 is used to accommodate a portion of the frame 120, effectively protecting the frame 120 and internal electrical components from external interference or damage. Another portion of the frame 120 extends out of the receiving cavity from the passage 112, facilitating connection with the wire 500 and improving the stability of the connection between the stator assembly 100 and the wire 500. Moreover, placing a portion of the frame 120 in the receiving cavity and the other portion extending out of the passage 112 makes the spatial layout of the entire stator assembly 100 more compact, avoiding excessive space waste and ensuring effective cooperation between different components, thereby improving the overall space utilization rate.

[0049] In some embodiments, the second segment 530 is located above the through port 112. In this case, the second segment 530 is located at a higher position outside the stator assembly 100, which provides more installation and connection space for the bending angle of the second segment 530, ensures that other components will not interfere with the second segment 530, and facilitates the arrangement and installation of other components.

[0050] In some embodiments, the second segment 530 is located below the passage 112 to avoid collisions with other components above it. Furthermore, regardless of whether the second segment 530 is located above or below the passage 112, its position can be better adjusted, extending the path of water into the coil and improving its waterproof performance. Moreover, by adjusting the orientation of the end of the fixing structure 600 away from the stator assembly 100, the coil components can be flexibly selected according to the needs of the actual installation environment, improving installation flexibility.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, the end of the fixing structure 600 away from the stator assembly 100 is upward or obliquely upward (not shown), and the second segment 530 is located above the passage 112. Figure 3 and Figure 4 As shown, in one embodiment, the end of the fixing structure 600 furthest from the stator assembly 100 is oriented downwards or diagonally downwards (not shown), and the second segment 530 is located below the passage opening 112. The closer the angled position between the first segment 520 and the second segment 530 is to the passage opening 112, the easier it is for water entering the fixing structure 600 to enter the stator assembly 100 through the passage opening 112, leading to poor insulation. By positioning the second segment 530 below or above the passage opening 112, the angled position between the first segment 520 and the second segment 530 is avoided from directly corresponding to the passage opening 112, increasing the difficulty of water infiltration and improving the waterproofing effect.

[0052] In some embodiments, the outer peripheral surface of the first segment 520 or the second segment 530 has annular ribs, and the fixing structure 600 covers the annular ribs. This reduces the gap between the wire 500 and the fixing structure 600, better preventing water from entering the coil component through the gap and improving the waterproof performance of the coil component. Furthermore, the annular ribs increase the contact area between the fixing structure 600 and the wire 500, allowing the fixing structure 600 to better cover the wire 500 and preventing the wire 500 from loosening or falling off due to external forces during use, thus preventing larger gaps.

[0053] In some embodiments, the conductor 500 includes multiple leads, each with an insulating layer covering its outer periphery. The conductor 500 also includes an insulating sheath covering a sealed section 550 and an exposed section 540, with the connecting section 510 located outside the insulating sheath. This significantly improves the waterproof performance of the coil components. Furthermore, the multiple bends preceding the connecting section 510 increase the distance and time water travels to reach it, further enhancing the waterproof performance of the coil components. The leads are used for connection with pins. The number of leads may be the same as or different from the number of pins. The insulating layer and insulating sheath improve the sealing and insulation effect of the conductor 500. In practical use, the conductor 500 can be round or flat wire.

[0054] Furthermore, the fixing structure 600 covers the connection position of the connecting section 510 and the pin, which can firmly fix the wire 500 and the pin together, reducing loosening or detachment caused by external impact, vibration or long-term use, improving the stability of the connection between the pin and the connecting section 510 of the wire 500, and ensuring that the electrical connection will not have poor contact or breakage due to mechanical external force. The fixing structure 600 is injection molded, which allows for precise control of its shape and size, ensuring the consistency and high precision of each component, and fully covering the connection position of the connecting section 510 of the wire 500 and the pin, forming a closed waterproof layer to prevent water from seeping into the coil components from the connection point.

[0055] like Figure 5 As shown, the coil component also includes a connecting block 710 and an insulating cover 720. The connecting block 710 covers a portion of the pin, and the insulating cover 720 has an injection cavity 721. The connecting block 710 is located inside the injection cavity 721. The gap in the injection cavity 721 is filled with sealing material, which seals the connection position between the pin and the wire 500, and forms a fixing structure 600.

[0056] In some embodiments, the connecting block 710 covers the connection position of the pin and the wire 500, effectively avoiding the risk of the electrical connection being exposed to the external environment, thereby ensuring the stability and reliability of the electrical connection. Moreover, by injecting sealing material into the gap of the injection cavity 721, the gap between the connecting block 710 and the insulating cover 720 can be filled to form a fixed structure 600, preventing water from entering the coil component and increasing the overall sealing performance of the component.

[0057] like Figure 2As shown, the coil component also includes an upper waterproof shell 210 and a lower waterproof shell 220. The upper waterproof shell 210 covers the upper part of the stator assembly 100, and the lower waterproof shell 220 covers the lower part of the stator assembly 100. An annular gap is formed between the upper waterproof shell 210 and the lower waterproof shell 220. The coil component also includes an encapsulation structure 400, which is formed by material injected into the annular gap and the assembly gap of the stator assembly 100.

[0058] In some embodiments, the upper waterproof shell 210, the lower waterproof shell 220, and the encapsulation structure 400 can surround the entire stator assembly 100, thereby forming a complete waterproof protective layer that can prevent water from entering the stator assembly 100 to a greater extent and enhance the overall waterproofness of the coil components.

[0059] like Figure 1 As shown, the coil component also includes an encapsulation structure 400, which includes a filling structure 410 and an annular encapsulation layer 420. The filling structure 410 is injected into the assembly gap of the stator assembly 100, and the encapsulation layer 420 surrounds the stator assembly 100. The filling structure 410, the encapsulation layer 420, and the fixing structure 600 are integrally injection molded.

[0060] In some embodiments, the stator assembly 100 includes a stator housing 110 and a coil structure located within the stator housing 110, with an assembly gap between the stator housing 110 and the coil structure. The encapsulation structure 400 includes a filling structure 410 and an encapsulation layer 420, which are integrally injection molded. The filling structure 410 is located within the assembly gap, and the encapsulation layer 420 is located within the annular gap between the upper waterproof housing 210 and the lower waterproof housing 220. This design fills the assembly gap between the stator housing 110 and the coil structure, thus securing the coil structure. Furthermore, the integral injection molding of the filling structure 410 and the encapsulation layer 420 simplifies the production process and improves the sealing effect and structural strength of the coil components. The coil structure includes a bobbin 120 and a coil wound around the bobbin 120.

[0061] An embodiment of this utility model also provides an electric valve, which includes a valve body and the aforementioned coil component. The valve body passes through the mounting hole 101 of the stator assembly 100. In this application, passing one end of the valve body through the mounting hole 101 of the stator assembly 100 allows for a more stable connection between the valve body and the coil component, reducing relative movement between them. This enables the entire electric valve to withstand more external forces or vibrations without loosening or damage. Furthermore, passing the valve body through the mounting hole 101 of the stator assembly 100 simplifies and simplifies the assembly of the valve body and coil component, reducing problems caused by improper assembly. It also effectively saves space, making the overall structure more compact, reducing the need for external connectors, and improving the overall integrity and reliability of the electric valve.
