[0050] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0051] The following is for reference. Figures 1-9 The wire harness structure 100 according to an embodiment of this application is described. The wire harness structure 100 is installed on a component to be fixed, which has a through-hole 201. The component to be fixed may include, but is not limited to, the housing 200 of the electrical control box 1000, or other cabinet or shell structures with through-holes 201. In this application, the housing 200 of the electrical control box 1000 used in the HVAC equipment 10000 is used as an example for description. The wire harness structure 100 can be constructed as a power harness (compressor wire harness structure) to realize the electrical connection between the electrical control box 1000 and the compressor in the HVAC equipment 10000.

[0052] The wire harness structure 100 according to an embodiment of this application includes: a mounting body 1, a sealing member 2, and an electrical connector 3.

[0053] The mounting body 1 is installed at the location of the component to be fixed and includes a wire passage 11. The sealing element 2 is disposed on the wire passage 11 of the mounting body 1, and the electrical connector 3 is disposed through the wire passage 11. The electrical connector 3 is used to realize the electrical connection between the two electrical components 400.

[0054] When the wire harness structure 100 is installed and mated with the component to be fixed, at least a portion of the wire passage portion 11 is arranged in the wire passage hole 201, and the sealing member 2 can form a seal between the outer periphery of the wire passage portion 11 and the inner peripheral wall of the wire passage hole 201 to prevent contaminants from entering through the gap between the wire passage hole 201 and the wire harness structure 100, which helps to improve the sealing and protection performance of the component to be fixed at the wire passage hole 201.

[0055] Specifically, the mounting body 1 is installed and fitted with the wire passage hole 201, and at least part of the wire passage part 11 is placed inside the wire passage hole 201. The sealing member 2 provided on the wire passage part 11 can abut against the inner peripheral wall of the wire passage hole 201 to form a seal in the wire passage hole 201, thereby improving the sealing and protection performance of the component to be fixed at the wire passage hole 201. This prevents contaminants (such as water, dust, etc.) from entering the component to be fixed through the gap between the mounting body 1 and the wire passage hole 201, which could cause contamination of the electrical components 400 in the component to be fixed or short circuits.

[0056] Meanwhile, the electrical connector 3 is used to realize the electrical connection between the two electrical components 400, and the electrical connector 3 is fixed in the mounting body 1 so as to be fixed at the wire hole 201 through the mounting body 1. The electrical connector 3 can be constructed as a metal wire. The electrical connector 3 can realize electrical connection with other electrical components 400, and the connection and mating method between the electrical connector 3 and other electrical components 400 is not limited here. For example, electrical connection can be realized by clamping or sleeved by conductive components, electrical connection can be realized by plug-in positioning and fixing, electrical connection can be realized by welding, etc. The "electrical component 400" can be a PCB board, and the "conductive component" can be constructed as a copper busbar.

[0057] It should be noted that currently, the compressor is equipped with a wiring harness structure 100, which can connect between the electrical control box 1000 and the power interface. To ensure proper wiring outflow from the electrical control box 1000, a wiring outlet hole is typically provided on the electrical control box 1000 body, allowing the wiring harness to pass through the outlet hole and extend outwards. In related technologies, a gap exists between the wiring harness structure 100 and the wiring outlet hole, resulting in poor sealing at the outlet hole. External dust or liquid contaminants can easily enter the electrical control box 1000 through this gap. Furthermore, in the event of a refrigerant leak in the air conditioning system containing the compressor, refrigerant can easily enter the electrical control box 1000, posing a significant safety hazard.

[0058] According to the wire harness structure 100 of the present application embodiment, the electrical connector 3 in the wire harness structure 100 passes through the mounting body 1 to realize the electrical connection function of the wire harness structure 100 through the electrical connector 3. The mounting body 1 achieves sealing with the wire hole 201 through the sealing member 2 to improve the sealing and protection performance of the wire harness structure 100 at the wire hole 201. The electrical connector 3 can pass through the mounting body 1 from the wire hole 201, thereby achieving the sealing and protection of the wire harness structure 100 at the wire hole 201 while meeting the wire passage requirements at the wire hole 201.

[0059] like Figure 7 As shown, in some embodiments of this application, the wire guide portion 11 includes a plug section 111 for plugging into the wire guide hole 201, and a sealing member 2 is disposed on the plug section 111 to form a seal between the plug section 111 and the wire guide hole 201.

[0060] Furthermore, during the installation and assembly of the wire harness structure 100 and the wire passage hole 201, the sealing element 2 can be pre-installed on the insertion section 111, and then the insertion section 111 can be inserted into the wire passage hole 201, thereby inserting the insertion end in the wire passage part 11 into the wire passage hole 201. The sealing element 2 arranged on the insertion section 111 can abut against the inner peripheral wall of the wire passage hole 201 to form a seal between the insertion section 111 and the wire passage hole 201.

[0061] It is understandable that the wire-passing part 11 includes a multi-segment structure. The plug-in end in the multi-segment structure is used to plug into and cooperate with the wire-passing hole 201 to guide the electrical connector 3 through the wire-passing hole 201, and can play a good constraining and fixing role for the electrical connector 3, so as to meet the wire-passing requirements at the wire-passing hole 201 and achieve sealing protection at the wire-passing hole 201.

[0062] In a further embodiment of this application, an annular groove 1111 is formed on the outer peripheral wall of the plug segment 111. The sealing member 2 is sleeved on the plug segment 111 and arranged in the annular groove 1111. The sealing member 2 is configured to form a seal between the inner peripheral wall of the wire hole 201 and the outer periphery of the plug segment 111, so as to form a sealing structure on the circumferential outer side of the plug segment 111, thereby improving the sealing and protection effect at the wire hole 201 and preventing contaminants from passing through the wire hole 201.

[0063] In some embodiments of this application, the seal 2 is constructed as a sealing ring, which is fitted onto the outer peripheral wall of the annular groove 1111. The sealing ring is an O-ring or a sealing ring with a lip.

[0064] In some other embodiments of this application, the seal 2 is formed on the outer peripheral wall of the annular groove 1111 by means of adhesive injection.

[0065] Taking the sealing element 2 as an example of a sealing ring, the shape of the annular groove 1111 matches the shape of the sealing ring, so that the sealing ring can be limited by the annular groove 1111 to prevent the sealing ring from coming off the insertion section 111, thereby improving the assembly reliability of the sealing ring and the insertion section 111 and preventing the sealing ring from moving on the insertion section 111 during the insertion of the insertion section 111 into the wire hole 201.

[0066] Reference Figure 7 As shown, when the sealing ring is arranged in the annular groove 1111, a portion of the sealing ring protrudes outward from the open end of the annular groove 1111, allowing the sealing ring to abut against and press against the inner circumferential wall of the wire hole 201. Simultaneously, when the insertion section 111 is inserted into the wire hole 201, the sealing ring is adapted to be deformed by the inner circumferential wall of the wire hole 201 and held within the annular groove 1111, thereby forming an annular sealing structure surrounding the insertion section 111, improving the sealing and protective effect at the wire hole 201.

[0067] In some alternative embodiments, the cross-sectional shape of the sealing ring is preferably circular or elliptical, and the cross-section of the annular groove 1111 is preferably rectangular.

[0068] In some embodiments of this application, the plug segment 111 is formed with a plurality of annular grooves 1111 spaced apart along the plugging direction, and the wire harness structure 100 is provided with a plurality of sealing rings, and each annular groove 1111 is provided with a sealing ring, so that a plurality of sealing rings can be provided on the plug segment 111, and multiple sealing is formed between the plug segment 111 and the wall of the wire hole 201 along the plugging direction by the multiple sealing rings, thereby improving the sealing and protection effect at the wire hole 201.

[0069] It should be noted that in the description of this application, "multiple" means two or more. That is, the wire harness structure 100 may be provided with two, three, four or more sealing rings. Correspondingly, the same number of annular grooves 1111 as the number of sealing rings are also formed on the plug section 111.

[0070] Furthermore, multiple sealing rings are arranged sequentially and at intervals in the insertion direction of the insertion section 111, and each sealing ring can form a seal between the insertion section 111 and the inner peripheral wall of the wire hole 201. The sealing rings are arranged at intervals from the insertion end of the insertion section 111 (i.e., the end where the insertion end first extends into the wire hole 201) to reduce the risk of the sealing rings coming off from the insertion end side. During the insertion and engagement of the insertion section 111 and the wire hole 201, multiple sealing rings sequentially form multiple seals. Even if one sealing ring fails, the sealing and protection effect at the wire hole 201 can still be guaranteed.

[0071] like Figure 8As shown, in some embodiments of this application, the plug-in end of the plug segment 111 has an arc-shaped chamfer 1112 in the circumferential direction. The "plug-in end" of the plug segment 111 refers to the end that is first inserted into the wire hole 201 during the plug-in process. By forming the arc-shaped chamfer 1112 at the plug segment 111, the difficulty of plugging the plug segment 111 into the wire hole 201 is reduced, thus facilitating the plug-in process.

[0072] Understandably, the arc-shaped chamfer 1112 at the plug-in end extends circumferentially, and the opening of the arc-shaped surface formed at the arc-shaped chamfer 1112 is opposite to the insertion direction of the plug-in segment 111. Therefore, when the plug-in segment 111 is inserted into the wire hole 201, the arc-shaped surface of the arc-shaped chamfer 1112 can abut against the inner circumferential wall of the wire hole 201, guiding the insertion of the plug-in segment 111 and facilitating the operator's insertion into the wire hole 201. Simultaneously, the arc-shaped chamfer 1112 at the plug-in end reduces the end face size, making it easier to insert the plug-in segment 111 into the wire hole 201.

[0073] In some embodiments of this application, the insertion end of the insertion segment 111 has a guide slope 1113 formed in the circumferential direction. The angle between the guide slope 1113 and the insertion segment 111 in the insertion direction is α, and satisfies the relationship: 0°<α≤5°. The guide slope 1113 can guide the insertion of the insertion segment 111 into the wire hole 201, thereby reducing the difficulty of the insertion and mating of the insertion segment 111 and the wire hole 201. Preferably, α is 1.5°.

[0074] It should be noted that the guide slope 1113 of the plug segment 111 is used for guiding engagement with the wire passage hole 201 to assist in the plug-in installation of the plug segment 111 and the wire passage hole 201. Therefore, in the plugging direction of the plug segment 111, the guide slope 1113 is configured to extend from the middle section of the plug segment 111 to the plugging end, thus making the plug segment 111 tapered towards the plugging end, facilitating the insertion of the plug segment 111 into the wire passage hole 201. The aforementioned "middle section" can be the mounting groove position of the plug segment 111 near the plugging end in the plugging direction, allowing the guide slope 1113 to guide engagement with the wire passage hole 201 before the seal 2 contacts and engages with the inner wall surface of the wire passage hole 201, thus aiding in assembly.

[0075] like Figure 7 As shown, in some embodiments of this application, the wire guide portion 11 further includes a limiting segment 112, which is connected to one end of the plug-in segment 111 and is used to limit the movement of the plug-in segment 111 along the plugging direction by engaging with the port of the wire guide hole 201.

[0076] The limiting segment 112 is connected to the other end of the plug-in segment 111 away from the plug-in end. When the plug-in segment 111 is plugged into the wire hole 201, the limiting segment 112 can be used to limit the plug-in segment 111 from being further inserted into the wire hole 201, thereby achieving the plug-in positioning of the plug-in segment 111 and the wire hole 201.

[0077] like Figure 7 As shown, in a further embodiment of this application, the limiting segment 112 includes a limiting flange 1121 and a base 1122. The limiting flange 1121 is connected to the end of the plug-in segment 111 and is used to limit the plug-in segment 111 from being inserted into the wire hole 201, thereby positioning the mounting body 1 with the component to be fixed. The base 1122 is connected to the side of the limiting flange 1121 away from the plug-in segment 111 and is used for the power supply connector 3 to pass through, thereby constraining the direction of part of the power supply connector 3.

[0078] In the insertion direction, the cross-sectional dimension of the limiting flange 1121 is larger than that of the insertion segment 111. When the insertion segment 111 is inserted into the wire hole 201 to a certain depth, the limiting flange 1121 can abut against the port of the component to be fixed that defines the wire hole 201, thereby limiting the insertion segment 111 from further extending into the wire hole 201, so as to position the mounting body 1 in the insertion direction in a matching manner with the component to be fixed.

[0079] Furthermore, the base 1122 is connected to the side surface of the limiting flange 1121 opposite to the plug section 111, and the base 1122 is used for the power supply connector 3 to pass through, thereby constraining the wires through the base 1122 to assist in the routing of the electrical connector 3. At the same time, the base 1122 can cover part of the electrical connector 3 in the circumferential direction to provide insulation protection for part of the electrical connector 3, and while constraining and guiding the routing of the electrical connector 3, it also prevents the electrical connector 3 from being damaged by excessive bending after passing through the mounting body 1.

[0080] In some embodiments of this application, the electrical connector 3 is integrally formed with the mounting body 1, so that the electrical connector 3 can be installed by the mounting body 1. After the mounting body 1 and the electrical connector 3 are installed and fitted, the electrical connector 3 is installed through the wire hole of the component to be fixed.

[0081] like Figure 7 As shown, in some embodiments of this application, there are multiple electrical connectors 3, which are spaced apart on the mounting body 1 to prevent interference between the multiple electrical connectors 3.

[0082] Reference Figure 7As shown, when the wire harness structure 100 is provided with multiple electrical connectors 3, the limiting section 112 is provided with the same number of bases 1122 as the electrical connectors 3. Each base 1122 is used to allow one electrical connector 3 to pass through, so that multiple bases 1122 can limit and constrain multiple electrical connectors 3 respectively, avoid interference between multiple electrical connectors 3, and improve the reliability and safety of the wire harness structure 100.

[0083] In some embodiments of this application, the mounting body 1 is provided with three sets of electrical connectors 3, which are arranged at intervals on the mounting body 1. The wiring harness structure 100 can be constructed as a compressor wiring harness structure, thus requiring three sets of electrical connectors 3 to meet the connection requirements between the compressor and the electrical control box 1000.

[0084] Furthermore, a wire through hole 201 is provided on the component to be fixed, and the wire through hole 201 is used to mate with the mounting body 1 in the wire harness structure 100. The opening shape of the wire through hole 201 can be set according to the number of electrical connectors 3 in the wire harness structure 100. For example: refer to Figure 7 When the wire harness structure 100 is provided with three electrical connectors 3, the three conductor bodies 31 are arranged side by side and spaced apart on the mounting body 1. Correspondingly, the opening shape of the wire hole 201 can be constructed as an elongated oval hole. When the wire harness structure 100 is provided with three electrical connectors 3, the three conductors are arranged in a triangle and spaced apart on the mounting body 1. Correspondingly, the opening shape of the wire hole 201 can be constructed as a triangle.

[0085] It should be noted that the number of electrical connectors 3 in the wiring harness structure 100 can be designed according to the wiring requirements of the wiring harness structure 100. Specifically, it can be two, three, four, etc. For example, when the wiring harness structure 100 is constructed as a power line connecting the electrical control box 1000 in the compressor and the power interface, the number of electrical connectors 3 in the wiring harness structure 100 can be three.

[0086] like Figure 7 As shown, in some embodiments of this application, the mounting body 1 further includes a fixing part 12. The fixing part 12 is connected to both sides of the limiting section 112, and the fixing part 12 is arranged on the outside of the wire hole 201 and used to fix it to the component to be fixed. By connecting and cooperating with the component to be fixed through the fixing part 12, the mounting body 1 is fixed at the wire hole 201 of the component to be fixed, thereby preventing the wire harness structure 100 from moving or coming out at the wire hole 201, and improving the connection reliability between the mounting body 1 and the component to be fixed.

[0087] Understandably, when the wire harness structure 100 is installed and engaged with the wire passage hole 201 via the mounting body 1, the insertion segment 111 in the mounting body 1 engages with the wire passage hole 201, and the limiting segment 112 is used to position and engage with the component to be fixed, thereby achieving initial positioning of the mounting body 1 and the component to be fixed. Simultaneously, the fixing part 12 connected to the limiting segment 112 is also located outside the wire passage hole 201, and the fixing part 12 is used to connect and engage with the connecting structure on the component to be fixed, thereby achieving installation and fixation of the mounting body 1 and the component to be fixed.

[0088] In a further embodiment of this application, the fixing part 12 is provided with a mounting hole 121, which is used for the connector 300 to pass through in a first direction, so that the fixing part 12 and the component to be fixed can be connected and fixed by the connector 300 cooperating with the connection structure of the component to be fixed. The installation method is simple and highly reliable.

[0089] Specifically, the connector 300 can be constructed as a threaded connection component such as a bolt, and the connection structure on the part to be fixed can be constructed as a nut or a threaded hole, etc. Taking the connector 300 as a bolt as an example, after the bolt passes through the mounting hole 121, the bolt can engage with the thread at the connection structure, thereby connecting and fixing the fixing part 12 to the part to be fixed.

[0090] In some embodiments of this application, the fixing part 12 is provided with a plurality of mounting holes 121, and correspondingly, the component to be fixed is also provided with a plurality of connecting structures corresponding to the plurality of mounting holes 121 respectively. The plurality of correspondingly arranged mounting holes 121 and connecting structures can be connected and fixed by a plurality of connectors 300 respectively, so as to further improve the connection reliability between the fixing part 12 and the component to be fixed.

[0091] Among them, at least two of the multiple mounting holes 121 are respectively arranged on both sides of the insertion section 111 to improve the fixing effect between the fixing part 12 and the part to be fixed.

[0092] In some embodiments of this application, the insertion direction of the connector 300 relative to the mounting hole 121 is perpendicular to the insertion direction of the plug section 111 relative to the wire hole 201, thereby adjusting the operating direction of the connector 300 during installation and fixing, and effectively preventing the mounting body 1 from shifting relative to the fixing member.

[0093] In some embodiments of this application, the fixing part 12 is provided with a positioning buckle, which is used to engage and position with the part to be fixed, thereby achieving secondary positioning between the mounting body 1 and the part to be fixed and improving the assembly effect between the mounting body 1 and the part to be fixed. It should be noted that the part to be fixed is provided with a positioning structure for engaging with the positioning buckle, such as a positioning groove or a positioning seat, which is sufficient to satisfy the positioning buckle engagement and positioning.

[0094] The positioning buckle is connected to the inside side of the fixing part 12 near the part to be fixed, so that the positioning buckle can be arranged near the part to be fixed, which facilitates the positioning buckle and the part to be fixed to be positioned and connected.

[0095] During the installation and assembly process between the mounting body 1 and the component to be fixed, the insertion section 111 is first inserted into the wire hole 201, and the limiting section 112 is initially positioned at the wire hole 201. Then, the positioning buckle is engaged with the positioning structure on the component to be fixed to achieve secondary positioning between the mounting body 1 and the component to be fixed. At this time, the mounting holes 121 on the fixing part 12 can be aligned with the connecting structure on the component to be fixed, so as to further connect and fix the mounting body 1 and the component to be fixed through the connector 300, thereby assembling the mounting body 1 onto the component to be fixed.

[0096] In some embodiments of this application, the snap-fit ​​installation direction of the positioning buckle is parallel to the through-mounting direction of the connector 300 relative to the mounting hole 121. After the positioning buckle is snap-fitted and positioned with the component to be fixed, it can restrict the translation of the mounting body 1 and prevent the plug segment 111 from coming out of the wire hole 201. It can also assist in positioning the mounting hole 121 on the fixing part 12 with the connection structure on the component to be fixed, improve the convenience of installation and cooperation between the mounting body 1 and the component to be fixed, reduce the assembly difficulty of the wire harness structure 100, and help improve the assembly efficiency of the wire harness structure 100.

[0097] In some embodiments of this application, the mounting body 1 is provided with at least two sets of electrical connectors 3, and the at least two sets of electrical connectors and fixing parts 12 are arranged along a second direction, with the first direction and the second direction being perpendicular to each other.

[0098] Therefore, when the wire harness structure 100 is installed into the box 200, the hole structure formed on the box 200 is set to face the user, so that the operator can directly hit the screws and other connecting parts, reducing the difficulty of installation.

[0099] According to the second aspect embodiment of this application, the electrical control box 1000 includes the above-described wiring harness structure 100, which is used to electrically connect and cooperate with the electrical components 400 in the electrical control box 1000.

[0100] Furthermore, the compressor is provided with a power interface, and the wiring harness structure 100 can be configured as a wiring harness in the electrical control box 1000 that is electrically connected to the power interface of the compressor. That is, the wiring harness structure 100 can be constructed as a compressor wiring harness structure to realize the electrical connection between the electrical control box 1000 and the compressor.

[0101] Therefore, by using the aforementioned wiring harness structure 100 to route the wiring at the outlet hole of the electrical control box 1000 while simultaneously forming a seal, the sealing performance of the electrical control box 1000 can be improved, preventing dust or liquid contaminants from entering the electrical control box 1000 and enhancing the protective effect of the electrical control box 1000. Furthermore, in the event of refrigerant leakage, the sealing structure can prevent refrigerant from entering the electrical control box 1000, avoiding safety issues such as combustion or explosion, and improving the safety of the compressor during operation.

[0102] It should be noted that the refrigerant used in the compressor can be R32 (difluoromethane), R600a (isobutane), R290 (propane), etc., meaning that the refrigerant is flammable. If flammable refrigerant leaks and enters the electrical control box 1000, it will pose a risk of explosion at the electrical control box 1000. In this application, the electrical control box 1000 is sealed at the mating point between the wire harness structure 100 and the box body 200 (i.e., the mating area between the wire hole 201 and the plug section 111) to prevent contaminants or refrigerant from entering the electrical control box 1000, thereby reducing safety hazards and improving the safety of the electrical control box 1000.

[0103] like Figure 6 As shown in a further embodiment of this application, the electrical control box 1000 includes a box body 200. The outer wall of the box body 200 is provided with a terminal block 210 having a wire passage hole 201. The wire passage hole 201 is used to insert and cooperate with the wire passage part 11. The electrical connector 3, which passes through the wire passage hole 201 and extends into the box body 200, can be electrically connected to the electrical component 400 inside the box body 200. Moreover, the terminal block 210 is used to fix the mounting body 1 to the mounting body 1 at the wire passage hole 201, thereby holding the sealing member 2 between the mounting body 1 and the inner peripheral wall of the wire passage hole 201, and improving the sealing effect of the electrical control box 1000 at the wire passage hole 201.

[0104] Among them, the terminal block 210 is an installation structure on the box 200 for the wire harness structure 100 to pass through and to connect and fix the mounting body 1 to the box 200.

[0105] In a further embodiment of this application, the terminal block 210 includes a main body 211 and a connecting plate 212. The main body 211 forms the aforementioned wire passage hole 201. The connecting plate 212 is connected to the outer peripheral wall of the main body 211, and the connecting plate 212 extends away from the wire passage hole 201 to arrange the connecting plate 212 in an area suitable for avoiding the wire passage hole 201. The fixing part 12 can be configured to be provided on one side of the connecting plate 212 in the thickness direction. The operator can perform installation operations on one side of the connecting plate 212 in the thickness direction, such as: snapping the positioning buckle into the snap-fit ​​groove, threading the connector 300 through the mounting hole 121 and connecting it to the connecting plate 212, etc.

[0106] The main body 211 defines a wire hole 201, and the wire hole 201 is inserted into the mounting body 1 in the wire harness structure 100 to form a seal between the inner peripheral wall of the wire hole 201 and the mounting body 1 through the sealing member 2.

[0107] Reference Figure 6 As shown, the seat body 211 is connected to the outer wall of the box 200 to form an outwardly protruding seat structure on the outside of the box 200, which facilitates the operator to operate outside the box 200. A connecting plate 212 is formed on the outer peripheral wall of the seat body 211, which is used to connect and cooperate with the fixing part 12 in the mounting body 1.

[0108] In some embodiments of this application, the electrical control box 1000 further includes a connector 300, which can pass through the fixing part 12 of the mounting body 1 and can connect and fix the fixing part 12 to the connecting plate 212, thereby realizing the connection and fixation between the mounting body 1 and the terminal block 210.

[0109] The connector 300 can be constructed as a threaded connector. The fixing part 12 has a through hole structure for the connector 300 to pass through, and the connecting plate 212 has a threaded hole structure that is threadedly engaged with the connector 300. The threaded hole structure can be integrated on the connecting plate or formed on the nut, so that the fixing part 12 can be fixed at the connecting plate 212 by the threaded connection of the threaded connector and the threaded hole structure, thereby realizing the connection and fixation between the mounting body 1 and the terminal block 210.

[0110] According to the third aspect of this application, the HVAC equipment 10000 includes a fan, a compressor, and the aforementioned electrical control box 1000. The wiring harness structure 100 in the electrical control box 1000 is a compressor wiring harness structure, and the electrical connector 3 is electrically connected to the compressor to realize the electrical connection and cooperation between the electrical control box 1000 and the compressor.

[0111] The electrical control box 1000 can be arranged inside the housing 2000 of the HVAC equipment 10000, and the electrical control box 1000 is set vertically. The wire hole 201 is formed on the side of the electrical control box 1000 to prevent contaminants (such as dust, rainwater, etc.) outside the housing 2000 from entering the electrical control box 1000 through the wire hole 201. Furthermore, the sealing and protection effect of the electrical control box 1000 at the terminal block 210 can be further improved by the sealing structure between the wire harness structure 100 and the box body 200.

[0112] Reference Figures 1-8 The following describes the installation process of assembling the wire harness structure 100 according to an embodiment of this application into the electrical control box 1000:

[0113] First, the sealing element 2 is placed on the mounting body 1, and the wire body 31 of the electrical connector 3 is inserted into the box 200 through the wire hole 201, with the mounting body 1 located on the outside of the box 200.

[0114] Next, the insertion section 111 in the wire-passing part 11 is inserted into the wire-passing hole 201 until the limiting section 112 abuts against the terminal block 210 to achieve initial positioning of the mounting body 1 and the terminal block 210. Then, the positioning buckle (not shown in the figure) is engaged with the connecting plate 212 to achieve secondary positioning of the mounting body 1 and the terminal block 210. At this time, the sealing element 2 can form a seal in the wire-passing hole 201 to improve the sealing and protection effect of the box 200 at the wire-passing hole 201. Furthermore, the fixing part 12 in the mounting body 1 is arranged correspondingly to the connecting structure (such as threaded hole) on the connecting plate 212.

[0115] Finally, after the connector 300 passes through the mounting hole 121 and engages with the threaded connection structure, the mounting body 1 is connected and fixed to the terminal block 210, thus completing the connection between the wire harness structure 100 and the box 200 at the terminal block 210.

[0116] It should be noted that the electrical connector 3 needs to be electrically connected to the electrical component 400 inside the box 200. The connection between the electrical connector 3 and the electrical component 400 can be performed after the electrical connector 3 passes through the wire hole 201 and extends into the box 200, such as after the main body 1 and the terminal block 210 are fixedly engaged.

[0117] In summary, the wire harness structure 100 according to the embodiments of this application has at least the following advantages over the prior art:

[0118] (1) The wire passage 11 in the main body 1 covers part of the electrical connector 3, and the plug section 111 in the wire passage 11 is used to plug into the wire passage hole 201. The sealing member 2 is sandwiched between the plug section 111 and the inner peripheral wall of the wire passage hole 201 to form a seal at the wire passage hole 201, thereby improving the sealing and protection performance at the wire passage hole 201 and effectively preventing contaminants and refrigerant located outside the box 200 from entering the box 200 through the wire passage hole 201.

[0119] (2) There are multiple sealing elements 2, so that multiple sealing elements 2 can form multiple seals at the wire hole 201, so as to further improve the sealing and protection effect at the wire hole 201;

[0120] (3) The terminal block 210 is located outside the box 200, which is convenient for operators to operate. In addition, during the assembly process of the main body 1 and the terminal block 210, the initial positioning can be achieved by the limiting part and the terminal block 210 limiting cooperation, and the secondary positioning can be achieved by the positioning buckle and the terminal block 210 positioning cooperation, so as to improve the assembly accuracy of the main body 1 and the terminal block 210, reduce the assembly difficulty and improve the assembly efficiency.

[0121] (4) An arc-shaped chamfer 1112 and a guide slope 1113 are formed at the plug end of the plug section 111 to reduce the difficulty of plugging and installing the plug section 111 and the wire hole 201.

[0122] (5) The mounting body 1 and the electrical connector 3 are integrally injection molded, which can fix the electrical connector 3 on the mounting body 1 without assembling the electrical connector 3 and the mounting body 1, thus saving assembly process and helping to improve the production and assembly efficiency of the wire harness structure 100.
