[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] High-power air conditioners typically use terminal blocks as intermediate connection components for high-voltage power lines in their control boxes. To avoid signal distortion or malfunctions caused by direct contact between high-voltage and low-voltage power lines, low-voltage wires must avoid the terminal block area and instead be routed around the edge of the control box or other locations far from the high-voltage power lines. This not only increases the overall structural size of the control box but also complicates the routing of high-voltage and low-voltage power lines, resulting in higher assembly difficulty and maintenance costs.

[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0019] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0020] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0021] like Figures 1 to 5As shown, according to an embodiment of this utility model, an electrical control box 10 is proposed, including a box body 1, an electrical control component, and a partition bracket 2. One side of the box body 1 is open to form an opening communicating with the inner cavity of the box body 1. A box cover 5 is connected to the opening of the box body 1, which can open or close the opening. The electrical control component includes an electrical control board 3, which is disposed inside the box body 1. The electrical control board 3 is connected to a low-voltage wire 6 and a high-voltage wire 7. The low-voltage wire 6 is typically used to transmit low-power, low-voltage signals such as control signals and communication signals to achieve precise control and information interaction of the equipment. The high-voltage wire 7 is used to transmit high-power, high-voltage electrical energy to provide power support for the main operating components of the equipment (such as compressors, fans, etc.).

[0022] The partition bracket 2 has a first wiring section 21 and a second wiring section 22 spaced apart along the first direction X, i.e., the height direction of the box 1. This creates two relatively independent areas in the vertical direction for the classified arrangement of high-voltage wires 7 and low-voltage wires 6. Placing the low-voltage wires 6 in the independent first wiring section 21 avoids the electromagnetic interference generated by the high-voltage wires 7 from affecting their signal transmission quality, ensuring stable and accurate transmission of low-voltage signals. Placing the high-voltage wires 7 in the second wiring section 22 prevents their electromagnetic interference from affecting the signal transmission of the low-voltage wires 6. The first wiring section 21 and the second wiring section 22, arranged along the height direction, fully utilize the space in the height direction of the box 1, avoiding the chaotic intertwining of high-voltage and low-voltage wires 6 in the same space. This makes the wiring inside the control box 10 more organized, reduces the space occupied by the wiring, improves the utilization rate of the internal space of the control box 10, simplifies the wiring path, makes the assembly process more convenient and faster, and reduces assembly difficulty and time costs.

[0023] The electrical control box 10 of this utility model has a partition bracket 2 set inside the box body 1. The partition bracket 2 has a first wiring section 21 and a second wiring section 22 distributed at intervals along the height direction of the box body 1. The low-voltage wire 6 and the high-voltage wire 7 are respectively housed in the independent first wiring section 21 and second wiring section 22, which simplifies the layout structure of the high-voltage and low-voltage wires 6, makes full use of the three-dimensional space of the box body 1 in the vertical direction, improves the compactness and space utilization of the internal layout of the electrical control box 10, and enables the low-voltage wire 6 and the high-voltage wire 7 to be wired in layers through physical isolation, which enhances the electromagnetic interference resistance of the electrical control components, ensures the transmission stability of low-voltage signals, optimizes the wiring path, reduces assembly complexity, and improves the integration degree and overall reliability of the electrical control box 10.

[0024] In some embodiments of this utility model, the first wiring part 21 includes a first wiring groove 211 extending along the second direction Y, the second direction Y being perpendicular to the first direction X, the top of the first wiring groove 211 having a first opening, and the low-voltage wire 6 being installed in the first wiring groove 211 through the first opening and extending along the first wiring groove 211.

[0025] like Figures 1 to 3 As shown, taking a common electrical control box 10 installation posture as an example, the box 1 is placed vertically, with its height direction perpendicular to the ground. The second direction Y is horizontal, allowing the first wiring trough 211 to provide a sufficiently long wiring path in the horizontal direction to accommodate the actual need for the low-voltage wire 6 to extend horizontally within the electrical control box 10. The top of the first wiring trough 211 has a first opening that penetrates the upper surface of the trough, forming a channel for the low-voltage wire 6 to be placed within the first wiring trough 211. This facilitates the quick insertion of the low-voltage wire 6 from top to bottom into the first wiring trough 211 through the first opening, without the need for tools or complex operations, thus improving assembly efficiency. After insertion, the low-voltage wire 6 is routed along the extension direction of the first wiring trough 211. The sidewalls of the trough physically constrain the wire, guiding it to arrange itself orderly along a preset path, improving the internal neatness of the electrical control box 10 and reducing the risk of short circuits due to wire crossings.

[0026] like Figure 2 As shown, in some embodiments of this utility model, at least one limiting buckle 212 is provided on the wall of the first cable tray 211 to limit the movement of the low-voltage wire 6. Specifically, the limiting buckle 212 may be an elastic hook protruding into the tray wall, or a limiting protrusion formed by a partial inward bend in the tray wall. Multiple limiting buckles 212 may be provided at intervals along the extension direction of the first cable tray 211 and evenly distributed on the left and right sides or one side of the tray wall to ensure the constraint effect on different positions of the low-voltage wire 6. When the low-voltage wire 6 naturally adheres to the bottom or side wall of the tray within the first cable tray 211, the side of the limiting buckle 212 facing the tray body will contact the outer surface of the wire, stopping and restricting the displacement of the low-voltage wire 6, thereby maintaining the stable arrangement of the wire.

[0027] like Figures 1 to 3As shown, in some embodiments of this utility model, the second wiring section 22 includes a second wiring groove 221 extending along the second direction Y, and a second opening is provided on one side of the second wiring groove 221. The control board is disposed on one side of the partition bracket 2, and the second wiring groove 221 has a second opening on the side facing the control board 3, that is, the second opening is opened on the side wall of the groove of the second wiring groove 221 near the control board 3, and the opening direction is towards the area where the control board 3 is located, so that the high-voltage wire 7 can be placed directly in the second wiring groove 221 through the second opening from near the control board 3 without having to go around to other positions in the box 1, shortening the connection path of the high-voltage wire 7 from the control board 3 to the wiring groove, and reducing line redundancy and crossing risks. After being installed, the high-voltage wire 7 is routed along the extension direction of the second wiring groove 221. The side wall of the groove of the second wiring groove 221 forms a physical constraint on the high-voltage wire 7, guiding it to be arranged in an orderly manner along a preset path, avoiding it from swinging randomly in the box 1 or crossing and tangling with the low-voltage wire 6, and ensuring the signal stability of the control system.

[0028] In some embodiments of this utility model, the electrical control box 10 further includes a terminal block 4, which is disposed inside the box body 1. The partition bracket 2 is provided with at least one first snap-fit ​​member 23, and the partition bracket 2 is snapped onto the side wall of the terminal block 4 through the first snap-fit ​​member 23.

[0029] like Figure 3-4 As shown, the terminal block 4 provides a reliable connection point for the high-voltage wire 7, enabling the wire to be stably and securely electrically connected to the control board 3. During wiring, a suitable length of insulation is stripped from one end of the high-voltage wire 7, exposing the internal conductor. This conductor is then inserted into the corresponding terminal of the terminal block 4. A screw is then passed through the crimping hole of the terminal and tightened, using the screw's clamping force to firmly fix the conductor of the high-voltage wire 7 to the terminal, thus achieving an electrical connection between the high-voltage wire 7 and the terminal block 4 and ensuring the reliability of the power supply to the control system. A first snap-fit ​​component 23 is provided on the side wall of the partition bracket 2 and protrudes outwards. There is one such component. The side wall of the terminal block 4 itself serves as the mating interface; this side wall can be the plane of the terminal block 4 closest to the partition bracket 2. The engagement of the first snap-fit ​​component 23 with the side wall of the terminal block 4 provides sufficient lateral / longitudinal constraint force, ensuring that the partition bracket 2 and the terminal block 4 remain relatively fixed. The number and distribution of the first snap-fit ​​component 23 can be adjusted according to actual assembly requirements. For example, there can be multiple first snap-fit ​​components 23, which are spaced along the second direction Y on the side wall of the partition bracket 2 and evenly distributed on the side wall to ensure balanced force.

[0030] In other embodiments, the first snap-fit ​​member 23 may also be disposed on the side wall of the terminal block 4, and a snap-fit ​​space is formed between the first snap-fit ​​member 23 and the side wall of the terminal block 4, so that the side wall of the partition bracket 2 can be directly snapped into the snap-fit ​​space, thereby realizing the rapid assembly of the two.

[0031] In some embodiments of this utility model, the first snap-fit ​​member 23 includes a first snap-fit ​​arm 231. One end of the first snap-fit ​​arm 231 is connected to the side wall of the partition bracket 2, and the other end extends away from the partition bracket 2. The extended end of the first snap-fit ​​arm 231 is bent toward the side wall of the terminal block 4 to form a first bent portion 232. The first bent portion 232 presses against the side wall of the terminal block 4 so that the partition bracket 2 is fixed on the terminal block 4.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, one end of the first snap-fit ​​arm 231 is integrally formed with the side wall of the partition bracket 2 by injection molding. The other end of the first snap-fit ​​arm 231 extends away from the partition bracket 2 and is set perpendicular to the side wall of the partition bracket 2. The extended end of the first snap-fit ​​arm 231 is bent toward the side wall of the terminal block 4 to form a first bent portion 232. The first bent portion 232 is perpendicular to the first snap-fit ​​wall. The inner surface of the first bent portion 232 directly contacts the side wall of the terminal block 4, and a mechanical clamping force is generated by the pressing action, thereby fixing the partition bracket 2 to the terminal block 4. During installation, bring the partition bracket 2 close to the terminal block 4, aligning the first bent portion 232 with the side wall of the terminal block 4. By pushing the partition bracket 2 laterally, the first locking arm 231 is compressed and deformed until the first bent portion 232 passes the corresponding position on the side wall of the terminal block 4. Then, the first locking arm 231 springs back or returns to its original position, and the first bent portion 232 presses tightly against the side wall of the terminal block 4, achieving a stable connection between the partition bracket 2 and the terminal block 4. During disassembly, press the first bent portion 232 in the opposite direction to release the pressure of the first bent portion 232 on the side wall of the terminal block 4. Then, move the partition bracket 2 out in the opposite direction to complete the separation of the two.

[0033] like Figure 2 As shown, in some embodiments of this utility model, a guide surface 2321 is provided at the end of the first bent portion 232 away from the partition bracket 2. The guide surface 2321 is an inclined surface, which extends downward at an inclination from away from the partition bracket 2 to close to the partition bracket 2. This allows the guide surface 2321 to guide the first bent portion 232 to make smooth contact with the side wall of the terminal block 4 during installation. The inclined surface presses and pushes the first snap-fit ​​arm 231 to elastically deform, reducing the insertion resistance during assembly and improving the smoothness and efficiency of the assembly of the partition bracket 2 and the terminal block 4.

[0034] In some embodiments of this utility model, the partition bracket 2 is further provided with a second snap-fit ​​member 24. The second snap-fit ​​member 24 includes a second snap-fit ​​arm 241. One end of the second snap-fit ​​arm 241 is connected to the side wall of the partition bracket 2, and the other end extends away from the partition bracket 2. The extended end of the second snap-fit ​​arm 241 is bent toward the side wall of the terminal block 4 to form a second bent portion 242. The second bent portion 242 presses against the side wall of the terminal block 4 so that the partition bracket 2 is fixed on the terminal block 4.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, one end of the second snap-fit ​​arm 241 is integrally formed with the side wall of the partition bracket 2 by injection molding. The other end of the second snap-fit ​​arm 241 extends away from the partition bracket 2 and is set perpendicular to the side wall of the partition bracket 2. The extended end of the second snap-fit ​​arm 241 is bent toward the side wall of the terminal block 4 to form a second bent portion 242. The second bent portion 242 is perpendicular to the second snap-fit ​​wall. The inner surface of the second bent portion 242 directly contacts the side wall of the terminal block 4, and a mechanical clamping force is generated by the pressing action, thereby fixing the partition bracket 2 to the terminal block 4. When the partition bracket 2 mates with the terminal block 4, the second snap-fit ​​arm 241 moves closer to the terminal block 4 along with the partition bracket 2. The second bent portion 242 gradually contacts the side wall of the terminal block 4. As the partition bracket 2 continues to be pushed, the second bent portion 242 applies a pushing force to the first snap-fit ​​arm 231 until the second bent portion 242 passes the corresponding position on the side wall of the terminal block 4. The second snap-fit ​​arm 241 relies on its own elastic restoring force to make the second bent portion 242 tightly adhere to and press against the side wall of the terminal block 4, forming a stable snap-fit ​​fixation.

[0036] The second aspect of this utility model provides an indoor air conditioning unit, including a housing and the aforementioned electrical control box 10, which is installed inside the housing. The housing includes a front frame and a panel. The panel is located at the front of the front frame, covering and protecting the front surface of the front frame, and can be opened to expose the front surface of the front frame when needed. The front frame has a mounting cavity with an open end, through which the electrical control box 10 is installed. By setting the electrical control box 10, the indoor air conditioning unit has a partition bracket 2 inside the housing 1. The partition bracket 2 has a first wiring section 21 and a second wiring section 22 spaced apart along the height direction of the housing 1, respectively housing the low-voltage wire 6 and the high-voltage wire 7 in the independent first wiring section 21 and second wiring section 22. This simplifies the layout of the high-voltage and low-voltage wires 6, improves the utilization rate of the internal space of the electrical control box 10, and enhances the electromagnetic interference resistance of the electrical control system through physical isolation, ensuring the transmission stability of low-voltage signals. At the same time, it optimizes the wiring path, reduces assembly complexity, and improves the integration and overall reliability of the electrical control box 10.

[0037] The third aspect of this utility model provides an air conditioner, including the aforementioned electrical control box 10, or including the aforementioned indoor air conditioner unit, and also including an outdoor air conditioner unit. The outdoor air conditioner unit includes a compressor, a heat exchanger, a four-way valve, an expansion valve, etc. The compressor, the outdoor heat exchanger, the four-way valve, the expansion valve, and the indoor heat exchanger are connected through refrigerant pipelines to form a refrigeration / heating system.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
