[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Currently, in the market, when designing the motherboard wiring path for appliances such as air conditioners, it is common to use injection-molded parts and sheet metal parts for wiring fixation. However, this approach poses a risk of wires touching motherboard components, and the sharp edges of sheet metal parts may damage the insulation layer of the wires, leading to safety hazards. Furthermore, while wire bundling is widely used, it requires additional cutting and bundling processes after bundling, resulting in low efficiency. Additionally, to meet electromagnetic compatibility requirements within the appliance box, strong and weak current wires must be routed separately, and the wires must pass through a ferrite core for fixation, leading to an increase in wire bundles and a decrease in overall aesthetics. Moreover, due to the limited space within the appliance box, when the layout is divided into a first and second layer, the wires on the lower second layer (i.e., the back of the motherboard) are prone to loosening and becoming detached, making it difficult for the ferrite core to effectively fix them, thus causing wiring safety hazards and electromagnetic compatibility issues.

[0030] To solve the above-mentioned problems, this utility model proposes a new wiring fixing structure, electrical box and air conditioner.

[0031] Please refer to the following: Figures 1 to 3 The wiring fixing structure proposed in this utility model includes a fixing plate 1, the front of the fixing plate 1 is fixedly connected to the circuit board 2; a wiring groove 3 is provided on the back of the fixing plate 1 for accommodating a wire that is electrically connected to the circuit board 2 at one end; a wire fixing component 4 is provided on the wire path of the wiring groove 3 for fixing the wire in the wiring groove 3.

[0032] This invention adds a fixing plate 1 that is fixedly connected to the back of the circuit board 2. By inserting the wires into the wiring groove 3 of the fixing plate 1 and using the wire fixing component 4 for effective fixation, one end of the wires is electrically connected to the front of the circuit board 2. This design not only effectively reduces the safety hazards of wiring and improves wiring efficiency, but also saves wiring space in the side area of ​​the circuit board 2, while avoiding the risk of the wiring touching the components on the circuit board 2.

[0033] In practical applications, the fixing plate 1 is manufactured using injection molding, which effectively prevents damage to the wire insulation layer caused by the sharp edges of sheet metal parts, thereby eliminating potential safety hazards. The back of the fixing plate 1 is equipped with a cable routing groove 3 and a cable fixing component 4, which improves cable routing efficiency compared to traditional cable tie fixing methods and is suitable for wiring needs in confined spaces.

[0034] like Figure 1 As shown, the back of the fixing plate 1 is provided with a first wiring groove 313 and a second wiring groove 323 at intervals, wherein the first wiring groove 313 is used to accommodate high-voltage wires and the second wiring groove 323 is used to accommodate low-voltage wires.

[0035] This invention provides a first wiring groove 313 and a second wiring groove 323 at intervals on the back of the fixing plate 1, which are used to accommodate high-voltage wires and low-voltage wires respectively, effectively separating high-voltage and low-voltage wires and effectively improving the electromagnetic compatibility of the wiring.

[0036] It should be noted that the gap between the first wiring trough 313 and the second wiring trough 323 can be flexibly adjusted according to specific needs. For example, the first wiring trough 313 can be arranged closer to the left side of the fixing plate 1, while the second wiring trough 323 can be arranged closer to the right side of the fixing plate 1.

[0037] See Figure 2 , Figure 3 One end of the high-voltage wire and the low-voltage wire passes around the fixing plate 1 and is connected to the high-voltage area and the low-voltage area on the front of the circuit board 2, respectively.

[0038] like Figure 1As shown, the first wiring trough 313 includes a first main wiring trough 311 that penetrates the front and rear sides of the fixing plate 1, and a plurality of first branch wiring troughs 312 that penetrate the left side of the fixing plate 1 and are connected to the first main wiring trough 311; the second wiring trough 323 includes a second main wiring trough 321 that penetrates the front and rear sides of the fixing plate 1, and a plurality of second branch wiring troughs 322 that penetrate the right side of the fixing plate 1 and are connected to the second main wiring trough 321.

[0039] This invention employs a first wiring trough 313 comprising a first main wiring trough 311 and multiple first branch wiring troughs 312. The first branch wiring troughs 312 separate and route the multiple high-voltage wires within the first main wiring trough 311, further effectively improving the reliability of electromagnetic compatibility. Similarly, the second wiring trough 323 also comprises a second main wiring trough 321 and multiple second branch wiring troughs 322. The second branch wiring troughs 322 separate and route the multiple low-voltage wires within the second main wiring trough 321, further effectively improving the reliability of electromagnetic compatibility.

[0040] It should be noted that the number of the first branch cable tray 312 and the second branch cable tray 322 can be flexibly adjusted according to specific needs. In other words, this utility model does not limit the number of branches of the cable tray 3, aiming to adapt to a wider range of wire layout needs.

[0041] like Figure 2 , Figures 4 to 6 As shown, the first branch groove 312 is provided with a magnetic ring chamber 5 and a fixing ring component 6 for fixing the magnetic ring in the magnetic ring chamber 5. Of course, in other optional embodiments, the first main groove 311 may also be provided with a magnetic ring chamber 5 and a fixing ring component 6.

[0042] This utility model provides a magnetic ring chamber 5 and a fixing ring component 6 in the first main wire groove 311 or the first branch wire groove 312 of the first wiring groove 313, which can effectively fix the magnetic ring on the high-voltage wire and further improve the reliability of electromagnetic compatibility.

[0043] like Figure 5 , Figure 6 As shown, the fixed ring component 6 includes a cover plate 61 rotatably covering the opening of the magnetic ring chamber 5, and an elastic stop block 63 provided on the side of the cover plate 61 facing the magnetic ring chamber 5 for locking onto the magnetic ring.

[0044] This utility model employs a fixing ring component 6, which includes a cover plate 61 and an elastic stop block 63. The cover plate 61 can be flipped open above the magnetic ring chamber 5 to expose the opening of the magnetic ring chamber 5, facilitating the placement of the magnetic ring. When the cover plate 61 is flipped closed, the elastic stop block 63 can lock the left and right sides of the magnetic ring and can be adjusted and fixed according to different sizes of magnetic rings, thereby achieving effective fixation of the magnetic ring.

[0045] like Figures 4 to 6As shown, one end of the cover plate 61 is rotatably connected to the wall of the first branch line groove 312 via a rotating shaft 62, and the other end of the cover plate 61 is provided with a buckle 64 for engaging with the wall of the first branch line groove 312.

[0046] Of course, in other alternative embodiments, one end of the cover plate 61 can also be rotatably connected to the wall of the first main line groove 311 via a pivot 62, and the other end of the cover plate 61 can also be provided with a buckle 64 for engaging with the wall of the first main line groove 311.

[0047] In practical applications, the rotating shaft 62 is cylindrical and is embedded in the hole above the wiring groove 3.

[0048] This invention employs a cover plate 61 that flips above the magnetic ring chamber 5 via a rotating shaft 62 to achieve an opening and closing function. After the cover plate 61 is flipped closed, it is secured to the fixing plate 1 by means of a buckle 64, ensuring that the cover plate 61 is firmly fixed, thereby effectively fixing the magnetic ring.

[0049] like Figure 2 As shown, multiple wire fixing components 4 are provided on the wire path of the first main wire groove 311 and the second main wire groove 321, and a wire fixing component 4 is provided on the wire path of each second branch wire groove 322.

[0050] It should be noted that since each first branch groove 312 is provided with a magnetic ring chamber 5 and a fixing ring component 6, the fixing component 4 can be omitted. Of course, in other optional embodiments, if a magnetic ring chamber 5 and a fixing ring component 6 are provided on the first main groove 311, then a fixing component 4 can be provided on the groove path of each second branch groove 322.

[0051] This invention can set an appropriate number of wire fixing components 4 according to the path length of the wiring groove 3 to ensure that the wire does not come out of the wiring groove 3, thereby achieving a stable fixation of the wire.

[0052] like Figure 7 As shown, the wire fixing component 4 includes an upper elastic rib 41 and a lower elastic rib disposed on opposite sides of the wire routing groove 3. The upper elastic rib 41 and the lower elastic rib cooperate to press the wire into the wire routing groove 3.

[0053] It should be noted that the cable fixing component 4 may use a flexible structure, but is not limited to this type of structure; any other cable fixing structure that meets the wiring requirements may also be used.

[0054] This invention employs a wire-fixing component 4 comprising an upper elastic rib 41 and a lower elastic rib, capable of adapting to wires of different diameters. When the wire is inserted into the cable tray 3, the lower elastic rib is springed up and interacts with the upper elastic rib 41, ensuring that the wire will not come out of the cable tray 3, thereby achieving reliable wire fixation.

[0055] The electrical box proposed in this utility model includes a box body, a circuit board 2 disposed inside the box body, and a wiring fixing structure. This wiring fixing structure ensures the safety of wiring within the electrical box and effectively improves wiring efficiency by inserting wires into the wiring groove 3 of the fixing plate 1 and securing them with the wire fixing component 4.

[0056] The air conditioner proposed in this utility model includes an electrical box. Given that the wiring inside the electrical box provides higher safety, the overall performance of the air conditioner is also effectively improved.

[0057] To facilitate understanding, a detailed explanation will now be given using the preferred wiring fixing structure as an example.

[0058] like Figures 1 to 7 As shown, the wiring fixing structure includes a fixing plate 1 formed by injection molding. The front side of the fixing plate 1 is fixedly connected to the back side of the circuit board 2, and the front side of the circuit board 2 is arranged with a low-voltage area and a high-voltage area.

[0059] The back of the mounting plate 1 is provided with a first main cable groove 311 and a second main cable groove 321 spaced apart. Two first branch cable grooves 312 are spaced apart on the left side of the first main cable groove 311, and two second branch cable grooves 322 are spaced apart on the right side of the second main cable groove 321. The first main cable groove 311 cooperates with the two first branch cable grooves 312 to achieve separate routing of the three high-voltage wires, so that the high-voltage wires can be connected to the high-voltage area on the front of the circuit board 2 after separation. Similarly, the second main cable groove 321 cooperates with the two second branch cable grooves 322 to achieve separate routing of the three low-voltage wires, so that the low-voltage wires can be connected to the low-voltage area on the front of the circuit board 2 after separation.

[0060] In this design, three wire-fixing components 4 are spaced apart along the wire path of the first main wire trough 311, three wire-fixing components 4 are spaced apart along the wire path of the second main wire trough 321, and one wire-fixing component 4 is located along the wire path of the second branch wire trough 322. The wire-fixing component 4 employs an elastic rib structure to flexibly adapt to wires of different diameters. This wire-fixing component 4 includes an upper elastic rib 41 and a lower elastic rib. When a wire is inserted into the wire routing trough 3, the lower elastic rib is lifted and interacts with the upper elastic rib 41, ensuring that the wire does not come out of the wire routing trough 3, thereby achieving reliable wire fixation.

[0061] The first branch wire groove 312 has a magnetic ring chamber 5 and a fixing ring component 6 along its groove path. The fixing ring component 6 consists of a cover plate 61 and an elastic stop block 63. The left edge of the cover plate 61 has a pivot 62, which allows it to flip over above the magnetic ring chamber 5 to achieve an opening and closing function. When a magnetic ring is installed on the wire, the cover plate 61 flips and closes, and is fixed on the left and right sides of the magnetic ring by means of the elastic stop block 63. The fixing can be adjusted according to different sizes of magnetic rings. In addition, the right edge of the cover plate 61 is provided with a buckle 64. After the cover plate 61 is flipped and closed by the pivot 62, the buckle 64 is embedded in the fixing plate 1, thereby effectively fixing the magnetic ring.

[0062] By adopting this wiring and fixing structure, after fixing the wires and magnetic rings inside the electrical box, the fixing plate 1 is firmly fixed to the sheet metal parts inside the electrical box by means of screws or other connections, thereby ensuring the safety of wiring inside the electrical box, improving wiring efficiency, and enhancing the safety and reliability of electromagnetic compatibility.

[0063] This invention employs a main board paired with a fixing plate within the electrical box. Wiring is routed through grooves on the fixing plate and effectively secured by a wire-fixing structure, significantly reducing wiring safety hazards, improving wiring efficiency, and saving wiring space. Furthermore, the wire grooves are divided into main grooves on the left and right sides, achieving separate routing of strong and weak current wires. The branch grooves are equipped with magnetic ring chambers and fixing ring components for fixing magnetic rings, effectively improving electromagnetic compatibility reliability. Therefore, this invention not only increases the diversity of wiring methods and forms but also further reduces wiring safety hazards, improves wiring efficiency, and enhances the electromagnetic compatibility reliability within the electrical box.
