[0023] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] The embodiment of the present application provides an electrical appliance box to solve the technical problem of low assembly efficiency of electrical appliance boxes in the prior art.

[0026] In the embodiments of the present application, Figure 1-Figure 3 As shown, the electrical box includes a box body 10, a main board 20 and a connecting nail 30, the box body 10 has a first side wall 11, and the first side wall 11 is provided with a first mounting hole 111; the main board 20 is arranged in the box body 10, and the main board 20 is provided with a second mounting hole 21 corresponding to the first mounting hole 111; the connecting nail 30 is provided with a first clamping portion 311 and a second clamping portion 312 at intervals, when the connecting nail 30 passes through the first mounting hole 111 and the second mounting hole 21 in sequence, the first clamping portion 311 is clamped with the first side wall 11, and the second clamping portion 312 is clamped with the main board 20, so that the main board 20 and the first side wall 11 are arranged relatively spaced apart.

[0027] The electrical box provided by the present application is provided with a first clamping portion 311 and a second clamping portion 312 at intervals on the connecting nail 30, and a first mounting hole 111 is provided on the first side wall 11, and a second mounting hole 21 is provided on the main board 20. The main board 20 can be fixed to the first side wall 11 after the connecting nail 30 passes through the first mounting hole 111 and the second mounting hole 21 in sequence. On the one hand, a sufficient safety distance can be created between the main board 20 and the side wall of the box body 10 to prevent the main board 20 from colliding with the box body 10 due to vibration when the air conditioner is running; on the other hand, the connecting nail 30 only needs to pass through the first mounting hole 111 and the second mounting hole 21 in one direction and be fixed, which makes the assembly between the main board 20 and the box body 10 simpler, and the whole process is simple to operate, saving time and effort, reducing the operating steps, reducing the operating difficulty, and effectively improving the installation efficiency of the electrical box.

[0028] For details, please refer to Figure 2 and Figure 3 The box body 10 is roughly in the shape of a rectangular parallelepiped, and the box body 10 has a plurality of side walls connected to each other. The first side wall 11 can be located on the bottom or side of the box body 10, and the box body 10 can be made of metal material. The box body 10 made of metal material is conducive to ensuring that the electrical box has good impact resistance during transportation, thereby improving the safety performance of the electrical box.

[0029] In order to improve the connection strength between the main board 20 and the first side wall 11 and prevent the main board 20 from falling off due to vibration during the operation of the air conditioner, a plurality of first mounting holes 111 can be set on the first side wall 11, and a plurality of second mounting holes 21 can be set on the main board 20. The plurality of first mounting holes 111 and the plurality of second mounting holes 21 are set in one-to-one correspondence, and then a plurality of connecting nails 30 are used to pass through the corresponding first mounting holes 111 and the second mounting holes 21 in sequence, so that the main board 20 can be stably installed on the first side wall 11.

[0030] It is worth mentioning that, since the connecting pin 30 first passes through the first mounting hole 111 and then passes through the second mounting hole 21, in this embodiment, the aperture of the first mounting hole 111 can be set larger, so that the aperture of the second mounting hole 21 is smaller than the aperture of the first mounting hole 111, and the size of the second clamping portion 312 is smaller than the size of the first clamping portion 311. In this way, when the connecting pin 30 is clamped with the first side wall 11, the second clamping portion 312 can easily pass through the first mounting hole 111, so that the second clamping portion 312 can be more conveniently clamped with the mainboard 20, and then the first clamping portion 311 is clamped with the first side wall 11 to complete the assembly, which is conducive to reducing the installation difficulty of the connecting pin 30 and improving the installation efficiency.

[0031] Optionally, in one embodiment, see Figure 3The connecting nail 30 includes a rod body 31, a first clamping portion 311 and a second clamping portion 312 are two V-shaped structures sequentially arranged on the rod body 31, and the scaling directions of the two V-shaped structures are the same.

[0032] For details, please refer to Figure 3 The rod body 31 can be a round rod or a square rod, and the first clamping portion 311 and the second clamping portion 312 are both arranged on the rod body 31 in an inverted V shape, and the angle of the V-shaped opening in the second clamping portion 312 is smaller than the angle of the V-shaped opening in the first clamping portion 311, so that the second clamping portion 312 can pass through the first mounting hole 111 more conveniently. Since the two V-shaped body structures have the same scaling direction, during installation, the two V-shaped body structures are both contracted inwardly, so that the first clamping portion 311 and the second clamping portion 312 can both pass through the corresponding mounting holes smoothly, and then the two V-shaped body structures are both expanded outwardly, so that the first clamping portion 311 is clamped to the first side wall 11, and the second clamping portion 312 is clamped to the mainboard 20. During the entire installation process, the connecting nail 30 only needs to be installed along one direction, which effectively improves the installation efficiency of the electrical box.

[0033] For further information, see Figure 3 The V-shaped body structure has a large end 3121 and a small end 3122, the small end 3122 is connected to the rod body 31, and the large end 3121 is spaced apart from the rod body 31, so that the V-shaped body structure can elastically deform and pass through the corresponding mounting hole.

[0034] In this embodiment, the V-shaped body structure is elastic. When the V-shaped body structure is subjected to external force, its large end 3121 can undergo elastic deformation in a direction close to the rod body 31, thereby ensuring that the V-shaped body structure can smoothly pass through the corresponding mounting hole. When the V-shaped body structure is not subjected to external force, its large end 3121 recovers its deformation in a direction away from the rod body 31, thereby connecting the mainboard 20 with the first side wall 11.

[0035] Optionally, in one embodiment, see Figure 3 The connecting pin 30 includes a rod body 31 and an anti-loosening cap 32. The anti-loosening cap 32, the first clamping portion 311 and the second clamping portion 312 are arranged on the rod body 31 in sequence along the first direction; the first side wall 11 is clamped between the anti-loosening cap 32 and the first clamping portion 311, and at least one of the anti-loosening cap 32 and the first clamping portion 311 can be elastically deformed and abutted against the first side wall 11, and the main board 20 is clamped between the first clamping portion 311 and the second clamping portion 312.

[0036] Specifically, the first direction is the length direction of the rod body 31, the anti-loosening cap 32 is arranged at one end of the rod body 31, the second clamping portion 312 is arranged at the other end of the rod body 31, the first clamping portion 311 is located between the anti-loosening cap 32 and the second clamping portion 312, and the V-shaped openings of the first clamping portion 311 and the second clamping portion 312 are both arranged toward the anti-loosening cap 32.

[0037] It is understandable that the distance between the anti-loosening cap 32 and the first clamping portion 311 is usually greater than the thickness of the first side wall 11, resulting in a gap after the first side wall 11 is clamped between the first clamping portion 311 and the anti-loosening cap 32. During the transportation of the air conditioner, the connecting nail 30 may fall off the first side wall 11. To this end, in this embodiment, at least one of the anti-loosening cap 32 and the first clamping portion 311 is elastically deformed to abut against the first side wall 11. Under the elastic action of the first clamping portion 311 or the anti-loosening cap 32, the side of the first side wall 11 facing the main board 20 can abut against the first clamping portion 311, and the side of the first side wall 11 facing away from the main board 20 can abut against the anti-loosening cap 32, which is conducive to preventing the connecting nail 30 from loosening and has a good anti-vibration effect.

[0038] For further information, see Figure 3 The anti-loosening cap 32 is an arc-shaped structure. One end of the rod body 31 close to the first clamping portion 311 is installed on the arc surface inside the anti-loosening cap 32, and the opposite ends of the arc-shaped structure are respectively in contact with the surface of one side of the first side wall 11 facing away from the main board 20. It can be understood that the anti-loosening cap 32 can be an arc-shaped structure with elastic function. When the connecting nail 30 is clamped with the first side wall 11, the large end 3121 of the first clamping portion 311 elastically deforms in the direction close to the rod body 31, and at the same time, the two ends of the anti-loosening cap 32 will be elastically deformed in the direction away from the first clamping portion 311 when squeezed by the first side wall 11, so that the first side wall 11 is installed between the first clamping portion 311 and the anti-loosening cap 32, and then the large end 3121 of the first clamping portion 311 restores the elastic deformation. At this time, the two ends of the anti-loosening cap 32 will continuously squeeze the first side wall 11, so that the connecting nail 30 is stably installed on the first side wall 11. When the air conditioner is transported, the connecting nail 30 will not loosen on the first side wall 11, thereby ensuring the safety performance of the air conditioner.

[0039] Optionally, in one embodiment, see Figure 3 Two first curling edges 33 are provided between the first clamping portion 311 and the anti-loosening cap 32, and the two first curling edges 33 are respectively located on both sides of the rod body 31, and the two first curling edges 33 are arranged back to back; and / or, two second curling edges 34 are provided between the second clamping portion 312 and the first clamping portion 311, and the two second curling edges 34 are respectively located on both sides of the rod body 31, and the two second curling edges 34 are arranged back to back.

[0040] For details, please refer to Figure 3 The first curling edge 33 is arranged in an arc shape, one end of the first curling edge 33 is connected to the first clamping portion 311, and the other end of the first curling edge 33 is connected to the anti-loosening cap 32, and the two first curling edges 33 are arranged symmetrically relative to the rod body 31. When the connecting nail 30 is clamped on the first side wall 11, the two first curling edges 33 are located in the first mounting hole 111, and the two first curling edges 33 can abut against the inner wall of the first mounting hole 111, thereby limiting the lateral displacement of the connecting nail 30 at the first mounting hole 111, further preventing the connecting nail 30 from loosening on the first side wall 11, and having a good anti-loosening performance.

[0041] Likewise, see Figure 3 The second curling edge 34 is arranged in an arc shape, one end of the second curling edge 34 is connected to the second clamping portion 312, and the other end of the second curling edge 34 is connected to the first clamping portion 311, and the two second curling edges 34 are arranged symmetrically with respect to the rod body 31. When the connecting nail 30 is clamped with the main board 20, the two second curling edges 34 are located in the second mounting hole 21, and the two second curling edges 34 can abut against the inner wall of the second mounting hole 21, thereby limiting the lateral displacement of the connecting nail 30 at the second mounting hole 21, avoiding the loosening of the connecting nail 30 on the main board 20, and having a good anti-loosening performance.

[0042] Optionally, in one embodiment, see Figure 1 , Figure 2 and Figure 5 The electrical box also includes an insulating diaphragm 40, on which a third mounting hole 41 corresponding to the second mounting hole 21 is provided. The connecting nail 30 passes through the first mounting hole 111, the third mounting hole 41 and the second mounting hole 21 in sequence to install the insulating diaphragm 40 between the first side wall 11 and the main board 20.

[0043] Specifically, when the box body 10 is made of metal, in order to prevent the main board 20 from contacting the box body 10 and causing a short circuit in the main board 20, the insulating film 40 is disposed between the first side wall 11 and the main board 20, so that the box body 10 can be prevented from being conductive, which is beneficial to improving the safety performance of the electrical box. In this embodiment, the insulating film 40 can be a high-voltage resistant PVC film, which is easy to manufacture, has a low cost, and has an insulating effect, effectively preventing the main board 20 from being broken down by current.

[0044] Optionally, in one embodiment, see Figure 1 , Figure 2 and Figure 5 The edge of the insulating film 40 is provided with a folded edge 42, and the folded edge 42 extends toward one side of the main board 20. Through the setting of the folded edge 42, the insulating film 40 is roughly in a semi-enclosed shape, and the main board 20 can be set inside the insulating film 40, which can provide a better protection effect for the main board 20.

[0045] It is understandable that an electrical box usually has a high-voltage side and a low-voltage side. In this embodiment, the folded edge 42 can be provided only at the edge of the insulating diaphragm 40 on the high-voltage side, thereby reducing the use of PVC material and reducing product costs.

[0046] Optionally, in one embodiment, see Figure 4 The box body 10 is provided with a fixing frame 12, which is used to connect with the air conditioner body. The fixing frame 12 can be arranged on the side of the first side wall 11 facing away from the main board 20, and a screw hole is arranged on the fixing frame 12, and the electrical box can be fixed to the air conditioner body by screw connection.

[0047] An embodiment of the present application also provides an air conditioner, which includes an electrical box. The specific structure of the electrical box refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
