[0051] The embodiments of this utility model 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 intended to explain this utility model, and should not be construed as limiting this utility model.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0053] The air conditioner 1000 of this utility model is described below with reference to the accompanying drawings.

[0054] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 1 and Figure 2As shown, the air conditioner 1000 includes: an air conditioner housing 3031, an electrical control box 200, and a junction box 100. The electrical control box 200 is disposed on the air conditioner housing 3031 and includes a housing 6 and a circuit board 5, with the circuit board 5 disposed inside the housing 6. The junction box 100 is located outside the air conditioner housing 3031 and is disposed on the housing 6. The junction box 100 includes a cover 1 for switching the junction box 100 on and off. The air conditioner 1000 includes a first wiring harness 8, one end of which is connected to the circuit board 5, and the other end of which extends into the junction box 100 and is adapted to connect with a second wiring harness 9 that is externally disposed in the electrical control box 200 and extends into the junction box.

[0055] The control box 200 is used to control the operation of the air conditioner 1000. The control box 200 is installed on the air conditioner housing 3031. The control box 200 includes a housing 6 and a circuit board 5. The circuit board 5 is a control component. The circuit board 5 is installed inside the housing 6. The housing 6 protects the circuit board 5 and improves the working stability of the circuit board 5.

[0056] The junction box 100 is disposed outside the air conditioner housing 3031 and is also disposed on the housing 6 of the electrical control box 200. The air conditioner 1000 includes a first wiring harness 8, one end of which is connected to the circuit board 5, and the other end of which extends into the junction box 100. The junction box 100 provides a support and limiting position for the first wiring harness 8, thereby facilitating the connection between the second wiring harness 9, which is externally disposed in the electrical control box 200, and the first wiring harness 8.

[0057] It is worth noting that when the air conditioner 1000 is installed at the point of use, other functional modules of the air conditioner 1000 need to be electrically connected to the electrical control box 200, such as the lighting module or the purification module; or other functional modules that do not belong to the air conditioner 1000 can be electrically connected to the electrical control box 200 for unified control, such as external lighting.

[0058] In related technologies, connecting the external wiring harness to the circuit board requires removing the control box, opening its casing, connecting the wiring harness, reinstalling the casing, and finally reinstalling the control box. This process is cumbersome and difficult. Furthermore, the limited space occupied by the air conditioner 1000 further complicates the operation.

[0059] Therefore, in this embodiment of the air conditioner 1000, a junction box 100 is added to the electrical control box 200. The junction box 100 provides a support and limiting position for the first wire harness 8. The first wire harness 8, pre-connected to the circuit board 5, extends into the junction box 100. The junction box 100 is close to the circuit board 5, which facilitates the introduction of the first wire harness 8 into the junction box 100. Furthermore, since the junction box 100 is located outside the air conditioner housing 3031, functional modules that need to connect to the circuit board 5 only need to extend the second wire harness 9 connected to the functional module into the junction box 100 and connect it to the first wire harness 8. This solves the docking problem of functional modules, simplifies the wiring steps, and makes operation convenient. The junction box 100 is constructed as a switchable box and includes a cover 1 for opening and closing the junction box 100. The design of the junction box 100 also facilitates the extension of the second wire harness 9 into the junction box 100, reducing the operational difficulty of connecting the second wire harness 9 and the first wire harness 8. The electrical control box 200 simplifies the wiring operation by incorporating the junction box 100, thus making it applicable to air conditioners 1000 where the installation space is relatively small.

[0060] According to the embodiment of the present utility model, the air conditioner 1000 adds a socket box 100 to the electrical control box 200. The first wire harness 8 pre-connected on the circuit board 5 extends into the socket box 100. The external second wire harness 9 that needs to be connected to the circuit board 5 only needs to extend to the socket box 100 and connect to the first wire harness 8. There is no need to disassemble, open, close and wire the electrical control box 200. The wiring steps are simple and the operation is convenient, which can improve the assembly efficiency of the air conditioner 1000.

[0061] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the first wire harness 8 and the second wire harness 9 are adapted to be connected by plug-in terminal assembly A at the ends of the wire harnesses. The plug box 100 is provided with a plug fixing structure 3, which is used to limit the plug-in terminal assembly A.

[0062] The first wire harness 8 and the second wire harness 9 are connected by a plug-in terminal assembly A. The connection between the first wire harness 8 and the second wire harness 9 is convenient and helps to improve the connection stability of the first wire harness 8 and the second wire harness 9.

[0063] The junction box 100 is equipped with a plug fixing structure 3. The junction box 100 is constructed as a switchable box. The plug fixing structure 3 is located inside the junction box 100. The junction box 100 can protect the plug fixing structure 3 and improve the reliability of the plug fixing structure 3.

[0064] The junction box 100 is equipped with a plug fixing structure 3, which limits the position of the plug terminal assembly A. This reduces the likelihood of separation due to impact at the connection point of the first wire harness 8 and the second wire harness 9, thus improving the connection stability of the first wire harness 8 and the second wire harness 9. Furthermore, the plug fixing structure 3 also limits the position of the first wire harness 8 and the second wire harness 9, reducing the likelihood of them shaking or coming out of the junction box 100, thereby improving operational reliability.

[0065] The plug-in terminal assembly A includes a male plug terminal and a female plug terminal. One of the male and female plug terminals is located at the end of the first wire harness 8 extending into the junction box 100, and the other male and female plug terminal is located at the end of the second wire harness 9 extending into the junction box 100. The male and female plug terminals are connected by plugging. The plug fixing structure 3 limits the position of the plug-in terminal assembly A. When the second wire harness 9 is not connected, by setting the plug fixing structure 3, the extent to which the first wire harness 8 protrudes from the junction box 100 can be reduced, improving the routing stability and neatness of the first wire harness 8, and reducing the damage to the first wire harness 8 during the transportation and installation of the air conditioner 1000; it also facilitates the connection between the first wire harness 8 and the second wire harness 9.

[0066] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the plug fixing structure 3 defines a slot 31 that extends along the first direction X, and the first wire harness 8 and the second wire harness 9 are adapted to be placed on both sides of the plug fixing structure 3 along the first direction X.

[0067] The plug fixing structure 3 defines a slot 31 that extends along the first direction X. The male and female plug terminals in the plug terminal assembly A are inserted and mated along the length of the plug terminal assembly A. The plug terminal assembly A is inserted into the slot 31 with its length extending along the first direction X. One end of the plug terminal assembly A in the first direction X is connected to the first wire harness 8, and the other end of the plug terminal assembly A in the first direction X is connected to the second wire harness 9. The first wire harness 8 and the second wire harness 9 are respectively placed on both sides of the plug fixing structure 3 along the first direction X.

[0068] Since the first wire harness 8 and the second wire harness 9 are respectively placed on both sides of the plug fixing structure 3 along the first direction X, the occurrence of the first wire harness 8 and the second wire harness 9 tangling together can be reduced, thereby improving the arrangement stability of the first wire harness 8 and the second wire harness 9.

[0069] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the plug fixing structure 3 includes latches disposed on both sides of the slot 31. The latches are spaced apart along a direction perpendicular to the first direction X. The latches limit the insertion of the plug terminal assembly A into the slot 31, thereby improving the arrangement stability of the plug terminal assembly A.

[0070] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the plug fixing structure 3 consists of multiple structures arranged at intervals along the second direction Y, which is perpendicular to the first direction X.

[0071] By setting multiple plug fixing structures 3, multiple plug-in terminal assemblies A can be limited to allow multiple first wire harnesses 8 and multiple second wire harnesses 9 to be connected accordingly, thereby allowing multiple functional modules to be connected to the control box 200, which is beneficial to improving the functionality of the air conditioner 1000; and the number of added functional modules can be selected to be connected to the control box 200 to achieve personalized design.

[0072] For example, there are two first wire harnesses 8 connected to the circuit board 5, each extending into the junction box 100 and towards two different plug fixing structures 3. One first wire harness 8 is used to connect to the second wire harness 9 of the lighting module, and the other first wire harness 8 is used to connect to the second wire harness 9 of the negative ion module. When a lighting module needs to be added, the second wire harness 9 of the lighting module is connected to the first wire harness 8 through a plug-in terminal assembly A, and the plug fixing structure 3 is used to limit the plug-in terminal assembly A. When a negative ion module needs to be added, the second wire harness 9 of the negative ion module is connected to the other first wire harness 8 through a plug-in terminal assembly A, and the plug fixing structure 3 is used to limit the plug-in terminal assembly A. Thus, the junction box 100 can accommodate multiple different functional modules, with simple wiring steps and convenient operation.

[0073] When a lighting module is required, the second wiring harness 9 of the lighting module is connected to the first wiring harness 8 via a plug-in terminal assembly A, and the plug fixing structure 3 is used to limit the position of the plug-in terminal assembly A; when no negative ion module is required, it does not need to be connected to the corresponding first wiring harness 8. Functional modules can be added separately to achieve personalized design.

[0074] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a wire harness constraint structure 4 is provided inside the junction box 100. The wire harness constraint structure 4 is used to constrain the extension direction of the wire harness.

[0075] By setting the wire harness constraint structure 4 to constrain the extension direction of the wire harness, the routing reliability of the wire harness can be improved, and the swaying of the wire harness and the situation of the wire harness coming out of the junction box 100 can be reduced.

[0076] In some embodiments of this utility model, such as Figure 3As shown, the wire harness constraint structure 4 defines a wiring groove 41, which has at least one corner position 411.

[0077] The wire harness is arranged in the wiring groove 41 and extends along the extension direction of the wiring groove 41, thereby constraining the extension direction of the wire harness.

[0078] The cable tray 41 has at least one corner position 411, where the cable harness changes its extension direction, thereby improving the limiting effect on the cable harness. When the cable harness is pulled, it is tightened at the corner position 411, which can improve the situation where the cable harness comes out of the cable tray 41 and improve the situation where the connection of the cable harness is separated, that is, improve the situation where the first cable harness 8 and the second cable harness 9 are disconnected under force, thereby improving the working reliability of the cable harness.

[0079] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the wire harness constraint structure 4 is constructed as a rib, and a wiring groove 41 is formed between two adjacent ribs.

[0080] In some other embodiments of this utility model, the wire harness constraint structure 4 includes wire buckles, which limit the wire harness. The wire harness cooperates with multiple wire buckles respectively, and the wire harness extends along the spacing direction of the multiple wire buckles, thereby constraining the extension direction of the wire harness.

[0081] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a wire harness constraint structure 4 is provided inside the junction box 100. The wire harness constraint structure 4 defines a wiring groove 41, which is used to constrain the extension direction of the wire harness. Each plug fixing structure 3 has a wiring groove 41 on each side in the first direction X.

[0082] By setting the wiring groove 41 to constrain the extension direction of the wire harness, the wiring reliability of the first wire harness 8 and / or the second wire harness 9 can be improved, and the shaking of the first wire harness 8 and / or the second wire harness 9 and the situation of it coming loose from the junction box 100 can be reduced.

[0083] Since each plug fixing structure 3 is provided with a wiring groove 41 on both sides in the first direction X, each first wire harness 8 and second wire harness 9 has its own wiring groove 41. Each first wire harness 8 and second wire harness 9 extends along different wiring grooves 41, which can improve the interference between adjacent first wire harnesses 8 and the interference between adjacent second wire harnesses 9, reduce wire harness tangling, and improve wiring reliability.

[0084] Optionally, each cable tray 41 has at least one corner position 411, where the cable harness changes its extension direction, thereby improving the limiting effect on the cable harness. When the cable harness is pulled, it is tightened at the corner position 411, which can improve the situation where the cable harness comes out of the cable tray 41 and improve the situation where the connection to the plug terminal assembly A is broken under force, thereby improving the working reliability of the cable harness.

[0085] In other embodiments of this utility model, such as Figure 8 As shown, a wire harness constraint structure 4 is provided inside the junction box 100. The wire harness constraint structure 4 defines a wiring groove 41. The wiring groove 41 is used to constrain the extension direction of the wire harness. The area where all the plug fixing structures 3 are located is the plug fixing area Z. Only one wiring groove 41 is provided on each of the two sides of the plug fixing area Z in the first direction X.

[0086] All first wire harnesses 8 are arranged in a wiring groove 41 and extend along the wiring groove 41, and all second wire harnesses 9 are arranged in a wiring groove 41 and extend along the wiring groove 41. This design improves the wiring stability of the first wire harnesses 8 and the second wire harnesses 9, reduces manufacturing costs, and helps improve assembly efficiency.

[0087] In some embodiments of this utility model, such as Figure 3 As shown, the side wall of the junction box 100 is provided with a wire hole 10 for threading wires, and one end of the wire routing groove 41 extends toward the wire hole 10 on the side wall of the junction box 100.

[0088] The first wire harness 8 and the second wire harness 9 extend into the junction box 100 through the wire hole 10 respectively. One end of the wiring groove 41 extends toward the wire hole 10. The first wire harness 8 and the second wire harness 9 directly enter the wiring groove 41 through the wire hole 10, which can improve the wiring stability of the first wire harness 8 and the second wire harness 9.

[0089] Furthermore, by providing a wire hole 10 on the side wall of the junction box 100, the wire hole 10 can also limit the first wire harness 8 and the second wire harness 9, thereby improving the routing reliability of the first wire harness 8 and the second wire harness 9 and reducing the shaking of the first wire harness 8 and the second wire harness 9.

[0090] In some embodiments of this utility model, the side wall of the junction box 100 is provided with a wire passage hole 10 for threading wires, and a sealing limiting member is provided at the wire passage hole 10, through which the wires pass.

[0091] The first wire harness 8 and the second wire harness 9 extend into the junction box 100 through the wire passage hole 10, respectively. The wire passage hole 10 can limit the movement of the first wire harness 8 and the second wire harness 9, improving the neatness of the wiring. Furthermore, since a sealing limiting element is provided at the wire passage hole 10, the wire harness passing through the sealing limiting element can improve the sealing performance of the junction box 100; it can also reduce the compression of the first wire harness 8 and the second wire harness 9, which helps to reduce the pulling of the first wire harness 8 and the second wire harness 9, and improve the working stability of the first wire harness 8 and the second wire harness 9.

[0092] In some embodiments of this utility model, such as Figure 2 As shown, the junction box 100 has an opening 211, a cover 1 for opening and closing the opening 211, and a plug fixing structure 3 facing the opening 211 so as to be exposed when the cover 1 is opened.

[0093] The junction box 100 is constructed as a switchable box. The junction box 100 has an opening 211. The cover 1 is used to open and close the opening 211. The plug fixing structure 3 is set facing the opening 211 so that it is exposed when the cover 1 is opened, which facilitates the extension of the second wire harness 9 to the junction box 100 and reduces the difficulty of connecting the second wire harness 9 and the first wire harness 8.

[0094] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the plug fixing structure 3 defines a slot 31 that extends along the first direction X. The first wire harness 8 and the second wire harness 9 are adapted to be placed on both sides of the plug fixing structure 3 along the first direction X. A clearance opening 311 is formed on the side of the slot 31 facing the cover 1. The clearance opening 311 extends along the first direction X and along the direction from the inside of the slot 31 to the cover 1. A wire pressing rib 11 is provided on the cover 1, which protrudes towards the inside of the plug box 100. The wire pressing rib 11 is opposite to the clearance opening 311 and is used to stop the plug terminal assembly A.

[0095] The plug fixing structure 3 defines a slot 31 extending along the first direction X. The male and female terminals of the plug terminal assembly A are inserted and mated along the length of the assembly. The plug terminal assembly A is inserted into the slot 31 with its length extending along the first direction X. One end of the plug terminal assembly A in the first direction X is connected to the first wire harness 8, and the other end is connected to the second wire harness 9. The first wire harness 8 and the second wire harness 9 are positioned on opposite sides of the plug fixing structure 3 along the first direction X. Because the first wire harness 8 and the second wire harness 9 are positioned on opposite sides of the plug fixing structure 3 along the first direction X, the occurrence of entanglement between the first wire harness 8 and the second wire harness 9 is reduced, improving the arrangement stability of the first wire harness 8 and the second wire harness 9.

[0096] The slot 31 is open on the side facing the cover 1 to form a clearance opening 311. The clearance opening 311 extends along the first direction X and along the direction from the inside of the slot 31 to the cover 1, so as to facilitate the insertion of the terminal assembly A into the slot 31.

[0097] The cover 1 is provided with a wire clamping rib 11 protruding towards the inside of the junction box 100. The wire clamping rib 11 is opposite to the relief opening 311.
