[0049] 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0050] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] The following is for reference. Figures 1-17 The electrical control box assembly 10 according to an embodiment of the present utility model is described.

[0053] like Figures 1-17 As shown, the electrical control box assembly 10 according to an embodiment of the present utility model includes: an electrical control box 1, a circuit board bracket 2, and a terminal block 3.

[0054] Specifically, such as Figures 1-17 As shown, the electrical control box 1 is along the first direction (such as...) Figure 1 The control box 1 has a mounting groove 11 on one side (in the x direction shown); a circuit board bracket 2 is disposed in the mounting groove 11; at least a portion of the terminal block 3 is disposed on the side of the control box 1 facing away from the opening of the mounting groove 11 along the first direction. It should be noted that the circuit board bracket 2 is used to fix the circuit board, and the circuit board bracket 2 is fixed relative to the control box 1. The wires on the terminal block 3 pass through the circuit board bracket 2 along the first direction and are connected to the circuit board.

[0055] Furthermore, such as Figures 11-17 As shown, the terminal block 3 is connected to the electrical control box 1. It can be understood that the electrical control box 1 is a sheet metal part. Even when the terminal block 3 and the electrical control box 1 are connected by threaded fasteners, due to the high strength of the sheet metal part, the threads on the electrical control box 1 are not easily scratched or deformed by the threaded fasteners. Thus, while fixing the terminal block 3, the threaded fasteners are prevented from stripping, thereby improving the reliability and stability of the installation of the terminal block 3.

[0056] like Figures 3-10 As shown, the terminal block 3 is snapped into the circuit board bracket 2. Therefore, by using the snap-fit ​​connection between the terminal block 3 and the circuit board bracket 2 instead of a screw connection, the terminal block 3 and the circuit board bracket 2 are secured without threaded fasteners, thus avoiding stripping of the threads and improving the reliability and stability of the terminal block 3 installation.

[0057] In summary, by using at least one of the two methods described above, the stripping of threaded fasteners can be avoided, thereby improving the reliability and stability of the terminal block 3 installation.

[0058] Furthermore, such as Figure 1 and Figure 2As shown, the electrical control box assembly 10 also includes an electrical control bracket 5 and an electrical control cover 6. The electrical control bracket 5 is located on the side of the electrical control box 1 opposite to the opening of the mounting groove 11 along the first direction and is connected to the electrical control box 1. At least a portion of the terminal block 3 passes through the electrical control bracket 5. There are two electrical control covers 6, which are respectively located on both sides of the electrical control box 1 along the first direction.

[0059] According to the embodiment of the present invention, the electrical control box assembly 10 has a mounting groove 11 on one side along a first direction; a circuit board bracket 2 is disposed in the mounting groove 11; at least a portion of the terminal block 3 is disposed on the side of the electrical control box 1 opposite to the opening of the mounting groove 11 along the first direction. The terminal block 3 is connected to the electrical control box 1. The electrical control box 1 is a sheet metal part, and the threads provided on the electrical control box 1 are not easily scratched or deformed by threaded fasteners. Therefore, while fixing the terminal block 3, the threaded fasteners are prevented from stripping, thereby improving the reliability and stability of the terminal block 3 installation. Furthermore, the snap-fit ​​connection between the terminal block 3 and the circuit board bracket 2 replaces the screw connection between the terminal block 3 and the circuit board bracket 2, so that the fixing of the terminal block 3 and the circuit board bracket 2 does not require threaded fasteners, which can also prevent the threaded fasteners from stripping, and further improve the reliability and stability of the terminal block 3 installation.

[0060] In some embodiments of this utility model, such as Figures 3-17 As shown, the electrical control box assembly 10 also includes a limiting structure 4, which is located on the side of the circuit board bracket 2 facing the terminal block 3 and connected to the circuit board bracket 2. The limiting structure 4 passes through the bottom wall of the mounting groove 11 and is used to fix the terminal block 3.

[0061] Understandably, since the limiting structure 4 is connected to the circuit board bracket 2 and passes through the bottom wall of the mounting groove 11, it can improve the connection reliability between the control box 1 and the circuit board bracket 2, and the limiting structure 4 can also play an auxiliary role in the installation between the circuit board bracket 2 and the control box 1. On the other hand, the limiting structure 4 is used to fix the terminal block 3, thereby further improving the installation stability and reliability of the terminal block 3.

[0062] In some embodiments of this utility model, such as Figures 3-6 and Figures 13-16 As shown, the limiting structure 4 includes a first baffle 41, which is disposed on one side of the terminal block 3 along the second direction, for the terminal block 3 in the second direction (e.g., Figure 1 The direction shown is fixed in the y-direction, and the first and second directions are perpendicular.

[0063] Understandably, since the first baffle 41 is located on one side of the terminal block 3 along the second direction, it can restrict the movement of the terminal block 3 along the second direction, thereby further improving the limiting function of the terminal block 3 and thus further improving the installation stability and reliability of the terminal block 3. Simultaneously, the first baffle 41 along a third direction (such as...) Figure 1 The first baffle 41 extends in the z direction (as shown), thereby increasing the limiting area of ​​the terminal block 3 and further improving the installation stability and reliability of the terminal block 3.

[0064] It should be noted that the first direction, the second direction, and the third direction are all perpendicular to each other. For example, in this invention, the first direction is the front-to-back direction of the air conditioner, the second direction is the up-and-down direction of the air conditioner, and the third direction is the left-to-right direction of the air conditioner. However, the first direction, the second direction, and the third direction can be changed according to the actual situation.

[0065] Furthermore, multiple first baffles 41 are arranged along a third direction, thereby further improving the installation stability and reliability of the terminal block 3. For example, in this utility model, there are two first baffles 41, but this utility model is not limited to this. There can be more first baffles 41, such as 3, 4, 5 or 6, etc.

[0066] In some embodiments of this utility model, such as Figures 3-6 and Figures 13-16 As shown, the limiting structure 4 includes multiple second baffles 42, which are respectively disposed on both sides of the terminal block 3 along the third direction, for fixing the terminal block 3 in the third direction. The first direction is perpendicular to the third direction.

[0067] Understandably, since multiple second baffles 42 are respectively disposed on both sides of the terminal block 3 along the third direction, that is, in the third direction, the terminal block 3 is located between multiple second baffles 42, thereby restricting the movement of the terminal block 3 along the third direction, thus further improving the limiting function of the terminal block 3, and thus further improving the installation stability and reliability of the terminal block 3. At the same time, the second baffles 42 extend along the second direction, thereby increasing the limiting area of ​​the second baffles 42 on the terminal block 3, further improving the installation stability and reliability of the terminal block 3.

[0068] For example, in this utility model, there are two second baffles 42, which are respectively disposed on both sides of the terminal block 3 along the third direction. However, this utility model is not limited to this. There can be more second baffles 42, such as 3, 4, 5 or 6.

[0069] Furthermore, such as Figures 3-6 and Figures 13-16As shown, the limiting structure 4 includes a first baffle 41. The first baffle 41 can be connected to the second baffle 42 or spaced apart. Multiple second baffles 42 are provided on the side of the first baffle 41 facing the terminal block 3. Thus, the limiting and fixing of the terminal block 3 can be better achieved.

[0070] In some embodiments of this utility model, such as Figures 3-6 As shown, the limiting structure 4 includes a third baffle 43, which includes a first sub-plate 431 and a second sub-plate 432. The first sub-plate 431 is connected to the circuit board support 2 and extends along the first direction. One end of the first sub-plate 431 facing away from the circuit board support 2 is connected to the second sub-plate 432. The second sub-plate 432 is located on the side of the terminal block 3 facing away from the circuit board support 2 and is used to fix the terminal block 3 in the first direction.

[0071] It is understandable that the relative position of the first sub-plate 431 and the terminal block 3 can restrict the direction of movement of the terminal block 3. For example, if the first sub-plate 431 is located on both sides of the terminal block 3 along the second direction, the movement of the terminal block 3 along the second direction can be restricted. If the first sub-plate 431 is located on both sides of the terminal block 3 along the third direction, the movement of the terminal block 3 along the third direction can be restricted.

[0072] The second subboard 432 restricts the terminal block 3 from moving away from the circuit board support 2. The side of the terminal block 3 away from the second subboard 432 is restricted by the circuit board support 2, thereby fixing the terminal block 3 in the first direction, which further improves the installation stability and reliability of the terminal block 3.

[0073] Furthermore, such as Figures 3-6 As shown, there are multiple third baffles 43, thereby further improving the installation stability and reliability of the terminal block 3. For example, in Figures 3-6 In the example shown, there are two third baffles 43 spaced apart along a third direction. However, the present invention is not limited to this. There can be more third baffles 43, such as 3, 4, 5 or 6.

[0074] In some embodiments of this utility model, such as Figures 3-10 As shown, the terminal block 3 passes through the bottom wall of the mounting groove 11 and snaps into the circuit board bracket 2. It is understood that the bottom wall of the mounting groove 11 has an opening, and the terminal block 3 passes through this opening to snap into the circuit board bracket 2. The terminal block 3's penetration through the bottom wall of the mounting groove 11 avoids installation interference between the terminal block 3, the control box 1, and the circuit board bracket 2. Furthermore, the snap-fit ​​connection between the terminal block 3 and the circuit board bracket 2 replaces the screw connection between them, eliminating the need for threaded fasteners and preventing stripping of the threads, thus improving the reliability and stability of the terminal block 3's installation.

[0075] In some embodiments of this utility model, such as Figures 3-10 As shown, the circuit board support 2 is provided with a buckle 21. The buckle 21 and the first baffle 41 are arranged in the second direction. The buckle 21 includes a connecting part 211 and a protrusion 212. The end of the connecting part 211 facing the first baffle 41 in the second direction is connected to the circuit board support 2. The protrusion 212 is located at the end of the connecting part 211 facing the terminal block 3 in the first direction, away from the first baffle 41. The terminal block 3 is engaged between the first baffle 41 and the protrusion 212.

[0076] Understandably, the terminal block 3 is fixed in the second direction by being snapped between the first baffle 41 and the protrusion 212. Simultaneously, the latch 21 has a certain elasticity, which can drive the protrusion 212 to move towards the terminal block 3 in the first direction. Since the second sub-plate 432 is located on the side of the terminal block 3 opposite to the circuit board support 2 and is used for fixing the terminal block 3 in the first direction, the connecting part 211 and the second sub-plate 432 can clamp the terminal block 3 in the first direction, further improving the installation stability and reliability of the terminal block 3.

[0077] In some embodiments of this utility model, such as Figures 8-9 As shown, the height of the protrusion 212 is greater than or equal to 0.8 mm; for example, the height of the protrusion 212 is 0.8 mm, 1.0 mm, 1.1 mm or 1.2 mm, etc., thereby making the protrusion 212 more reliable in limiting the terminal block 3 in the second direction.

[0078] In some embodiments of this utility model, such as Figures 8-9 As shown, in the second direction, the distance from the fixed end of the connecting part 211 to the side of the protrusion 212 facing the fixed end of the connecting part 211 is greater than or equal to 15mm, for example, 15mm, 16mm, 17mm or 18mm. This gives the connecting part 211 sufficient elasticity, allowing it to better engage with the terminal block 3, further improving the installation stability and reliability of the terminal block 3.

[0079] In some embodiments of this utility model, such as Figures 9-10 As shown, the connecting part 211 has a rib 213 on the side facing the terminal block 3. The rib 213 is located on the side of the protrusion 212 facing the first baffle 41. The rib 213 is adapted to abut against the side of the terminal block 3 facing the circuit board support 2.

[0080] It is understandable that the protruding rib 213 is designed so that the terminal block 3 presses against the protruding rib 213, which causes the connecting part 211 to deform to a certain extent (bending and protruding in the direction away from the terminal block 3 in the first direction). This gives the connecting part 211 sufficient elasticity, allowing the protruding part 212 to better engage with the terminal block 3, further improving the installation stability and reliability of the terminal block 3.

[0081] In some embodiments of this utility model, such as Figures 8-9 As shown, in the second direction, the end of the protrusion 212 facing away from the terminal block 3 has a guide slope 214, and in the direction from the circuit board support 2 to the terminal block 3, the guide slope 214 is inclined toward the direction close to the terminal block 3.

[0082] Understandably, during installation, the connector 3 can move along the guide ramp 214 in the second direction from the protrusion 212 to the first baffle 41. Simultaneously, along the first direction, the protrusion 212 moves away from the connector 3, eventually causing the connector 3 to abut against the first baffle 41. At the same time, the end of the connector 3 facing away from the first baffle 41 in the second direction abuts against the side of the protrusion 212 facing the first baffle 41 in the second direction. Then, driven by the elasticity of the latch 21, the protrusion 212 moves in the first direction towards the connector 3, thus achieving a latching connection between the connector 3 and the circuit board bracket 2. Therefore, the guide ramp 214 allows for smoother installation of the connector 3.

[0083] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the circuit board support 2 has a limiting groove 22 on the side facing the terminal block 3. One end of the connecting portion 211, away from the protrusion 212, is connected to the inner peripheral wall of the limiting groove 22, while the remaining portion is spaced apart from the inner peripheral wall of the limiting groove 22. It can be understood that the limiting groove 22 allows at least a portion of the connecting portion 211 to be disposed within the limiting groove 22, thereby preventing the connecting portion 211 from protruding from the surface of the circuit board support 2 facing the terminal block 3, thus avoiding interference with the installation of the terminal block 3.

[0084] In some embodiments of this utility model, such as Figure 8 and Figure 9As shown, a portion of the guide slope 214 extends onto the connecting portion 211. This increases the length of the guide slope 214, making it easier for the terminal block 3 to rest on it, thus improving the ease of installation. However, since at least a portion of the connecting portion 211 is located in the limiting groove 22, and a portion of the guide slope 214 extends to the connecting portion 211, a portion of the guide slope 214 can also be located in the limiting groove 22. Therefore, when installing the terminal block 3, the portion resting on the non-guide slope 214 of the latch 21 may interfere with the installation of the terminal block 3.

[0085] In some embodiments of this utility model, such as Figures 11-17 As shown, the terminal block 3 is located on the side of the electrical control box 1 facing away from the circuit board support 2 along the first direction, and is connected to the electrical control box 1 by fasteners. It can be understood that by having the terminal block 3 completely located on the side of the electrical control box 1 facing away from the circuit board support 2 along the first direction, the area of ​​the hole to be opened on the bottom wall of the mounting groove 11 of the electrical control box 1 can be reduced (only the through hole for the wire needs to be left), thus ensuring the structural strength of the electrical control box 1.

[0086] Meanwhile, the terminal block 3 is connected to the control box 1, and the control box 1 is relatively fixed to the circuit board bracket 2. This allows the terminal block 3 to be fixed to the circuit board bracket 2 without directly connecting to the circuit board bracket 2 via threaded fasteners, thus avoiding stripping of the threaded fasteners on the circuit board bracket 2. Furthermore, the connection between the terminal block 3 and the control box 1 via threaded fasteners, and the fact that the control box 1 is a sheet metal part, means that the threads on the control box 1 are not easily scratched or deformed by the threaded fasteners. This ensures that the terminal block 3 is fixed while preventing stripping of the threaded fasteners, thereby improving the reliability and stability of the terminal block 3 installation.

[0087] In some embodiments of this utility model, such as Figures 11-17 As shown, the bottom wall of the mounting groove 11 has a positioning hole 12, and the side of the terminal block 3 facing the circuit board support 2 has a positioning pin 31 that mates with the positioning hole 12. It can be understood that the positioning hole 12 facilitates the initial positioning of the terminal block 3 and the control box 1 during installation, thereby improving installation efficiency. Furthermore, it further enhances the reliability and stability of the installation between the terminal block 3 and the control box 1.

[0088] The following describes an air conditioner according to an embodiment of the present invention.

[0089] The air conditioner according to an embodiment of the present invention includes the above-described electrical control box assembly 10.
