[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0038] As Figures 1 to 3 shown, the first embodiment of the present utility model provides a coil component, including a stator assembly and a lead wire assembly 20. A plurality of pins 11 of the stator assembly are arranged side by side in sequence;

[0039] The lead wire assembly 20 includes lead wires 21 and a fixing structure. There are a plurality of lead wires 21. The fixing structure covers at least a part of each lead wire 21 along the extending direction of the lead wire assembly 20. The parts of the plurality of lead wires 21 encapsulated in the fixing structure are arranged side by side in sequence; among them, each lead wire 21 is connected to the corresponding at least one pin 11 in sequence.

[0040] Adopting this solution, the fixing structure covers at least a part of each lead wire 21, so that the order of the lead wires 21 in the lead wire assembly 20 is fixed, and the problem of wire order confusion will not occur. The plurality of lead wires 21 are connected to the corresponding at least one pin 11 in sequence, so that the order of the lead wires 21 is fixed when the stator assembly is connected to the lead wire assembly 20, and the problem of wire order confusion will not occur.

[0041] AsFigures 4 to 6 As shown, the fixing structure is the insulating sheath 22, and the cross-sectional shape of the insulating sheath 22 is oval, rectangular, rounded rectangular or oblong.

[0042] With such a setting, as Figure 4 shown, in the second embodiment of the present utility model, the cross-sectional shape of the insulating sheath 22 is oval. The edge of the oval insulating sheath 22 is smooth, occupies less space, and can adapt to the installation of the coil component of the expansion valve.

[0043] As Figure 5 shown, in the third embodiment of the present utility model, the cross-sectional shape of the insulating sheath 22 is rectangular, making the outer shape of the insulating sheath 22 more regular and convenient for installation.

[0044] As Figure 6 shown, in the fourth embodiment of the present utility model, the cross-sectional shape of the insulating sheath 22 is oblong, the edge is smooth and will not affect other components, the processing is convenient, and the cost is saved.

[0045] After the wire sequence at the connection position between the wire 21 and the stator assembly is fixed, each wire 21 and the pin 11 are arranged in sequence correspondingly. The wires 21 are arranged in sequence, and multiple wires 21 will not cross each other and then be connected to the pin 11. Therefore, the length of the cut wire 21 can be shortened, the cost is saved, and at the same time, the failure caused by multiple crossings or twists of the wire 21 is avoided.

[0046] As Figure 1 shown, the wire assembly 20 further includes a connector 30. The connector 30 is used to connect the power supply. The fixing structure is the insulating sheath 22. The wire 21 includes a first section 211, a second section, and a third section 213 that are connected in sequence. The second section is encapsulated in the insulating sheath 22. The first section 211 is exposed outside the insulating sheath 22 and is electrically connected to the pin 11. The third section 213 is exposed outside the insulating sheath 22 and is connected to the connector 30. Among them, multiple second sections are arranged side by side in sequence. The arrangement order of multiple first sections 211 is the same as that of multiple second sections. The initial arrangement order of multiple third sections 213 is the same as that of multiple second sections. When multiple third sections 213 are connected to the connector 30, the actual arrangement order is adjusted adaptively.

[0047] With such a setting, the first section 211 of the wire 21 is electrically connected to the pin 11, the third section 213 of the wire 21 is connected to the connector 30, and the connector 30 connects the power supply to energize the stator assembly. The second sections are arranged in sequence and encapsulated inside the insulating sheath 22, so that the arrangement order of the wire 21 is fixed and the problem of wire sequence confusion will not occur. The wire sequence at the connection position between the wire 21 and the connector 30 is cross-adjusted according to the coil energization sequence.

[0048] Further, the fixing structure is an insulating sheath 22, and the coil component further includes a sealing structure 40, and the sealing structure 40 at least encapsulates the connection position of the wire 21 and the pin 11. With such a setting, the sealing structure 40 encapsulates the connection position of the wire 21 and the pin 11 to ensure the sealing and insulating performance of the connection position of the pin 11 and the wire 21.

[0049] Further, the sealing structure 40 is a potting structure or an injection molding structure.

[0050] The coil component includes a coil body part, the coil body part includes a stator assembly and an injection molding part, the stator assembly includes a winding, a stator pole plate and a stator housing, and the injection molding part at least encapsulates the winding and part of the pins.

[0051] The sealing structure 40 can be processed by an injection molding process. Specifically, the sealing structure 40 and the injection molding part can be integrally processed with the stator assembly as an insert or at least part of the components of the stator assembly as an insert, or the injection molding part on the coil body part can be processed first, and then the sealing structure 40 can be injection molded with the coil body part as an insert. Specifically, as Figure 7 shown, in the fifth embodiment of the present utility model, the wire 21 includes a first section 211 and a second section connected in sequence. The second section is encapsulated in the insulating sheath 22, the first section 211 is exposed outside the insulating sheath 22 and connected to the pin 11, and the sealing structure 40 encapsulates a part of the insulating sheath 22, the pin 11, and the first section 211.

[0052] With such a setting, the sealing structure 40 encapsulates the pin 11 and the first section 211, making the connection between the wire 21 and the pin 11 tighter. During the operation of the expansion valve, it prevents external water vapor from entering the connection position of the pin 11 and the wire 21, and ensures the sealing and insulating performance of the coil component. When encapsulating the first section 211 of the wire 21, the sealing structure 40 encapsulates a part of the insulating sheath 22, making the connection between the sealing structure 40 and the wire assembly 20 more stable and not prone to falling off, ensuring that the expansion valve is not prone to failure during operation.

[0053] In other embodiments of the present application, the injection molding part on the coil body part can also be processed first, and an insulating shell is fixed at the injection molding part at the connection of the pin and the wire, and an insulating material is potted in the insulating shell to form the sealing structure 40. Specifically, as Figure 8 shown, in the sixth embodiment of the present utility model, the wire 21 includes a first section 211 and a second section connected in sequence. The second section is encapsulated in the insulating sheath 22, the first section 211 is exposed outside the insulating sheath 22, the first section 211 includes a connecting section 2111 and an insulating section 2112 connected to each other, the connecting section 2111 is electrically connected to the pin 11, the insulating section 2112 is connected to the second section, and the sealing structure 40 encapsulates the pin 11, the connecting section 2111, and at least a part of the insulating section 2112, and the insulating sheath 22 is exposed outside the sealing structure 40.

[0054] With such an arrangement, the connecting section 2111, the pin 11, and at least a part of the insulating section 2112 are encapsulated within the sealing structure 40, making the connection between the connecting section 2111 and the pin 11 more stable, less likely to become detached, preventing external moisture from entering the connection position between the pin 11 and the connecting section 2111 of the wire 21, and ensuring the sealed insulation performance of the coil component. The sealing structure 40 encapsulates at least a part of the insulating section 2112, making the coverage of the sealing structure 40 over the connecting section 2111 and the pin 11 more complete. Not encapsulating all of the insulating section 2112 makes the wire assembly 20 more flexible when it undergoes torsion or angular changes.

[0055] The wire 21 includes a metal wire and an insulating layer that wraps the metal wire. The connecting section 2111 only has the metal wire and is not wrapped by the insulating layer, enabling the connecting section 2111 to achieve electrical connection with the pin 11. The insulating section 2112 has a metal wire and an insulating layer, and the insulating layer prevents short circuits during use.

[0056] Furthermore, the multiple wires 21 have different colors, and the multiple wires 21 with different colors are arranged in a set color sequence, and the first color in the set color sequence is the standard color.

[0057] With such an arrangement, the multiple wires 21 are set to have different colors, and different colored wires represent different power-on sequences. The multiple wires are arranged in the order of the set colors, enabling the multiple wires to be numbered according to their colors. Thus, the wires 21 of different colors are connected to the pins 11, ensuring the corresponding relationship between the wires 21 and the pins 11 and enabling the coil component to operate according to the corresponding power-on sequence.

[0058] As Figure 9 shown, in the seventh embodiment of the present utility model, the wire 21 of the standard color is the first wire. The wire 21 includes the first wire, the second wire, the third wire, the fourth wire, the fifth wire, and the sixth wire arranged in sequence. The pin 11 includes the first pin, the second pin, the third pin, the fourth pin, the fifth pin, and the sixth pin arranged in sequence. The wire 21 and the pin 11 are electrically connected in one-to-one correspondence according to the same serial numbers.

[0059] With such an arrangement, the wire 21 and the pin 11 with pre-set wire sequences are numbered in order respectively. The six pins 11 and the six wires 21 are electrically connected in one-to-one correspondence according to the same serial numbers, making the connection sequence between the wire 21 and the pin 11 clearer. During the installation process of the coil component, the corresponding sequence of the pins 11 and the wires 21 will not be confused, and the installation is convenient, fast, and time-saving.

[0060] As Figure 1As shown in the figure, in the first embodiment of the present utility model, the wire 21 of the standard color is the first wire. The wire 21 includes the first wire, the second wire, the third wire, the fourth wire, and the fifth wire arranged in sequence. The pin 11 includes the first pin, the second pin, the third pin, the fourth pin, the fifth pin, and the sixth pin arranged in sequence. The first wire is electrically connected to the first pin, the second wire is electrically connected to the second pin, the third wire is electrically connected to the third pin and the fourth pin respectively, the fourth wire is electrically connected to the fifth pin, and the fifth wire is electrically connected to the sixth pin.

[0061] With such a setting, there are five wires 21 and six pins 11. The third wire is set to be electrically connected to the third pin and the fourth pin respectively, and the other wires 21 and the other pins 11 are electrically connected in sequence. During the installation process of the coil component, the wires 21 and the pins 11 are connected according to the set serial numbers and corresponding relationships, and the connection order of the pins 11 and the wires 21 will not be confused, and the installation is convenient and fast, saving time.

[0062] Furthermore, the wire 21 is directly connected to the pin 11, or the wire 21 and the pin 11 are riveted through a terminal, or the wire 21 and the pin 11 are electrically connected by being welded to the circuit board respectively.

[0063] With such a setting, the wire 21 can be directly connected to the pin 11 to realize the electrical connection between the stator component and the wire component 20. Or, the wire 21 and the pin 11 can be fixed by terminal riveting. The terminal riveting makes the connection between the wire 21 and the pin 11 more firm and not prone to falling off, ensuring the stability of the connection between the wire 21 and the pin 11. Or, multiple wires 21 and multiple pins 11 are respectively welded to the circuit board, and the electrical connection between the wire 21 and the pin 11 is realized through the circuit board.

[0064] The advantages of the present utility model are as follows:

[0065] 1. During the production of the coil component of the wire component 20 that fixes the wire sequence arrangement of the wire 21, the wire component 20 has sorted the wire sequence arrangement of the wire 21 and positioned it through the insulating sheath 22, and there will be no problem of the wire sequence of the wire 21 being disordered due to misoperation or other reasons, avoiding the failure of the expansion valve caused by the wrong corresponding relationship between the wire 21 and the pin 11 due to wire sequence confusion;

[0066] 2. The wire component 20 that fixes the wire sequence arrangement of the wire 21 can check the wire sequence of the wire 21 at any position close to the insulating sheath 22 of the wire component 20. When the expansion valve fails, the connection relationship between the wire 21 and the pin 11 can be quickly determined, and the failure cause can be quickly investigated;

[0067] 3. The multiple wires 21 of the wire assembly 20 are arranged in sequence such that the distance between the pin 11 corresponding to the wire 21 and the connector 30 is the shortest, which can shorten the length of the cut wire 21 and simultaneously reduce the plastic encapsulation or potting length of the sealing structure 40, saving costs.

[0068] 4. After the wire sequence of the wire 21 is fixed at the position where the wire 21 is connected to the stator assembly, each wire 21 and the pin 11 are arranged in sequence correspondingly, and the wire 21 will not cross and then be connected to the pin 11, reducing the bending radius of the wire 21 in the width direction or the direction with a smaller diameter, thereby shortening the used length of the wire 21 and shortening the length of the cut wire 21.

[0072] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings.
