Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air handling unit. Background Technology

[0002] In related technologies, air handling units typically employ a fixed structure with a single installation orientation. For example, the heat exchange cabinet and air supply cabinet may be arranged horizontally side-by-side or stacked vertically, or the heat exchange and air supply components may be housed in an integrated cabinet. This fixed structure has significant limitations. In actual installation, when encountering narrow ceiling spaces or complex scenarios requiring ductwork around beams, fixed-structure air handling units often struggle to adapt to on-site installation conditions. Furthermore, the fixed orientation of the air inlet and outlet sides of a fixed structure cannot be adjusted according to actual installation needs, greatly reducing the installation flexibility of the air handling unit and severely limiting its application range.

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.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0065] In existing technologies, air handling units typically employ a fixed structure with a single installation orientation. For example, heat exchange cabinets and air supply cabinets are arranged horizontally side-by-side or stacked vertically, or the heat exchange and air supply components are housed in a single cabinet, making them unsuitable for narrow ceilings or complex scenarios requiring ductwork around beams. The fixed orientation of the air inlet and outlet sides in these structures cannot be adjusted according to actual installation needs, further limiting the practical application scenarios of air handling units. In ceiling spaces with limited height or installation environments with obstructing beams, traditional air handling units often lead to installation difficulties or duct damage due to the inability to adjust airflow paths and equipment layout.

[0066] To address the aforementioned problems, this application proposes an air handling unit. In some embodiments, such as Figures 1 to 8 As shown, the air handling unit includes a heat exchange cabinet 100 and a blower cabinet 200. The heat exchange cabinet 100 has a first connecting port 110 and a second connecting port 120 arranged opposite to each other, with the first connecting port 110 located at the bottom and the second connecting port 120 located at the top. The blower cabinet 200 has an air inlet 210 and an air outlet 220 arranged opposite to each other. The air handling unit has a first installation state and a second installation state. In the first installation state, the blower cabinet 200 and the heat exchange cabinet 100 are arranged adjacent to each other horizontally, and the first connecting port 110 or the second connecting port 120 is connected to the air inlet 210. In the second installation state, the blower cabinet 200 and the heat exchange cabinet 100 are arranged adjacent to each other vertically, and the air inlet 210 is connected to the first connecting port 110 or the second connecting port 120.

[0067] Specifically, when horizontal installation is required, such as Figures 1 to 4 As shown, the heat exchanger cabinet 100 and the air supply cabinet 200 are arranged in parallel, with the first connecting port 110 or the second connecting port 120 located on the same side and directly connected to the air inlet 210, forming a horizontally connected airflow channel. When vertical installation is required, such as... Figures 5 to 8 As shown, the air supply cabinet 200 can be placed above or below the heat exchange cabinet 100. The air inlet 210 can be connected to either the first connecting port 110 or the second connecting port 120 to form a vertical airflow circulation. In both installation states, the airflow path is ensured to remain continuous by adjusting the cabinet position and interface connection relationship.

[0068] like Figures 1 to 8As shown, this application allows for selection of horizontal or vertical layouts based on the installation environment, solving the problem of traditional air handling units being unable to adapt to narrow spaces. When vertical space is limited, such as in ceiling spaces with low ceiling heights, the first installation configuration can be used to reduce the overall height of the equipment; when horizontal space is limited, the second installation configuration can be used to reduce the width occupied by the equipment. By adjusting the interface between the air supply cabinet 200 and the heat exchange cabinet 100, flexible configuration of the airflow direction can be achieved, avoiding increased wind resistance caused by ductwork around beams. The airflow path remains consistent in both installation configurations, ensuring that heat exchange efficiency is not affected by layout changes.

[0069] The heat exchange cabinet 100 houses a heat exchange component 810, such as an evaporator. It also contains sensor lines or data transmission lines for monitoring room temperature, pipe temperature, refrigerant levels, and valves on the heat exchange piping connected to the evaporator. Because condensation occurs as air flows through the heat exchange cabinet 100, a drip tray 300 is installed at the bottom of the cabinet, specifically on the side of the first connection port 110, to collect the condensate generated during the heat exchange between the air and the heat exchange component 810. Therefore, the heat exchange cabinet 100 must be positioned in a fixed orientation during use. Specifically, the first connection port 110 is located at the bottom of the cabinet, the second connection port 120 is located at the top, and the drip tray 300 is located on the side of the first connection port 110.

[0070] The air supply cabinet 200 houses a fan 820. The air inlet side of the fan 820 is connected to the air inlet 210, and the air outlet side of the fan 820 is connected to the air outlet 220, thus defining the airflow direction within the air supply cabinet 200. Understandably, there is a significant gap between the outer shell of the heat exchange cabinet 100 and the fan 820, allowing the electrical control component 500 to be positioned within this gap, thereby fully utilizing the internal space of the air supply cabinet 200. The electrical control component 500 is electrically connected to the fan 820 and various electrical components within the heat exchange cabinet 100, enabling power supply and control.

[0071] Among them, the electronic control component 500 refers to a modular unit that centrally controls the operating logic of the air handling unit. Specifically, it can be implemented by combining an integrated circuit board with a heat sink housing 230. The electronic control component 500 can provide a unified processing interface for detection signals.

[0072] Based on the above explanation, the changes in the installation layout of the heat exchanger cabinet 100 and the air supply cabinet 200 involve not only improvements to the installation structure but also improvements to the wiring path. The installation structure and wiring path will be explained separately below.

[0073] In the first installation state, the air inlet 210 of the air supply cabinet 200 can be set on the same side as the first connecting port 110 and connected through an air duct to achieve upward air outlet. The air inlet 210 of the air supply cabinet 200 can also be set on the same side as the second connecting port 120 and connected through an air duct to achieve downward air outlet. In the first installation state, the air inlet 210 of the air supply cabinet 200 can be connected to any connecting port to change the air outlet direction and achieve flexible configuration of the airflow path.

[0074] Taking the example of the air inlet 210 of the air supply cabinet 200 being located on the same side as the first connecting port 110 and connected through an air duct, the explanation is as follows: Figures 1 to 4 As shown, the heat exchange cabinet 100 can be located on the left side of the air supply cabinet 200 or on the right side of the air supply cabinet 200. This application does not limit this.

[0075] In the first installation state, the heat exchange cabinet 100 and the air supply cabinet 200 can be installed and connected via the support frame 700. Specifically, the support frame 700 has an air duct and two openings 720 communicating with the air duct; when the air handling unit is in the first installation state, both the heat exchange cabinet 100 and the air supply cabinet 200 are connected to the support frame 700, the first communication port 110 is connected to one of the openings 720, and the air inlet 210 is connected to the other opening 720.

[0076] The support frame 700 can be a metal frame or an injection-molded shell structure, with an internal air duct forming to transfer airflow. Two openings 720 are located at the top of the support frame 700. The first connection port 110 of the heat exchange cabinet 100 and the air inlet 210 of the air supply cabinet 200 respectively connect to the two openings 720, forming a complete airflow path. In this embodiment, the integrated air duct support frame 700 replaces scattered duct components, achieving a pre-standardized design of the airflow channel and reducing on-site construction complexity. The double openings 720 of the support frame 700 overcome the limitations of traditional fixed interfaces, allowing for flexible adjustment of the equipment layout according to the installation space.

[0077] For ease of description, the opening 720 on the left is defined as the first opening 720, and the opening 720 on the right is defined as the second opening 720. Both the first and second interfaces can use standardized interfaces. In the first installation state, the first connection port 110 of the heat exchange cabinet 100 can be connected to the first opening 720, and the air inlet 210 of the air supply cabinet 200 can be connected to the second opening 720; alternatively, the first connection port 110 of the heat exchange cabinet 100 can be connected to the second opening 720, and the air inlet 210 of the air supply cabinet 200 can be connected to the first opening 720. This application does not limit the choice of which option is correct.

[0078] Based on the above embodiments, the inner wall of the air duct of the support frame 700 can be equipped with a guide plate to reduce airflow resistance, for example, by adopting an arc-shaped curved surface guide structure. A quick-release buckle can be installed at the opening 720 to facilitate quick docking of the heat exchange cabinet 100 and the air supply cabinet 200.

[0079] A sealing structure, such as a sealing ring, can be provided at the connection between the first connection port 110 of the heat exchange cabinet 100, the air inlet 210 of the air supply cabinet 200 and the corresponding opening 720, thereby reducing the risk of airflow leakage from the joint between the support frame 700 and the heat exchange cabinet 100, and the joint between the support frame 700 and the air supply cabinet 200.

[0080] The first opening 720 and the second opening 720 can be designed as circular or rectangular through holes. The first opening 720 and the second opening 720 must be consistent to allow for easy switching between docking with the heat exchange cabinet 100 or the air supply cabinet 200. Sealing strips can be fitted to the edges of the first opening 720 and the second opening 720 to improve the sealing at the docking point and reduce airflow leakage when docking with the heat exchange cabinet 100 and the air supply cabinet 200.

[0081] For the second installation state, such as Figures 5 to 9 As shown, the air supply cabinet 200 can be located at the top or bottom of the heat exchange cabinet 100, and this application does not limit this.

[0082] Specifically, in some examples, the air supply cabinet 200 is located at the top of the heat exchange cabinet 100, the air outlet 220 of the air supply cabinet 200 is located at the top, the air inlet 210 of the air supply cabinet 200 is located at the bottom, and the air inlet 210 of the air supply cabinet 200 is connected to the second connection port 120 of the heat exchange cabinet 100. The second connection port 120, the first connection port 110, the air inlet 210 and the air outlet 220 are connected in sequence to realize the top air outlet mode.

[0083] In other examples, the air supply cabinet 200 is located at the bottom of the heat exchange cabinet 100, the air outlet 220 of the air supply cabinet 200 is located at the bottom, the air inlet 210 of the air supply cabinet 200 is located at the top, and the air inlet 210 of the air supply cabinet 200 is connected to the first connecting port 110 of the heat exchange cabinet 100. The first connecting port 110, the second connecting port 120, the air inlet 210 and the air outlet 220 are connected in sequence to realize the bottom air outlet mode.

[0084] This embodiment achieves switchability of airflow direction through dual-path configuration, which can adapt to different installation scenarios and achieve different air outlet modes without changing the structure of the heat exchange cabinet 100 and the air supply cabinet 200.

[0085] In the second installation state described above, regardless of whether the air supply cabinet 200 is located at the top or bottom of the heat exchange cabinet 100, the air supply cabinet 200 is connected through the air inlet 210. Based on this, in this embodiment, a locking component 250 can be added to the air supply cabinet 200. The locking component 250 refers to the connecting component used to achieve mechanical fixation between cabinets, which can be implemented by a metal pin with a snap-fit ​​structure or a rotary lock. A first locking part 131 and a second locking part 132 are also provided on the heat exchange cabinet 100. The first locking part 131 and the second locking part 132 refer to the fixing structures provided on the outer surface of the heat exchange cabinet 100, which can be implemented by grooves, protrusions, or snap-fit ​​slots. Both the first locking part 131 and the second locking part 132 can provide a suitable fixing position for the locking component 250, thereby adjusting the connection point of the locking component 250 according to the installation direction.

[0086] Specifically, the first locking part 131 is located near the first connecting port 110, and the second locking part 132 is located near the second connecting port 120. When the air handling unit is in the second installation state, if the air supply cabinet 200 is at the top of the heat exchange cabinet 100, the locking member 250 cooperates with the first locking part 131 to fix the heat exchange cabinet 100 and the air supply cabinet 200; if the air supply cabinet 200 is located at the bottom of the heat exchange cabinet 100, the locking member 250 cooperates with the second locking part 132 to fix the heat exchange cabinet 100 and the air supply cabinet 200. Through the selective cooperation of the locking member 250 with the double locking parts, reliable fixation of the heat exchange cabinet 100 and the air supply cabinet 200 under different airflow directions is ensured, while simplifying the structural adaptation steps during installation.

[0087] As previously explained, the wiring path needs to be adjusted in both the first and second installation states. Understandably, in the first installation state, if the air supply cabinet 200 is located on the left or right side of the heat exchange cabinet 100, the wiring path also needs to be adjusted; in the second installation state, if the air supply cabinet 200 is located on the top or bottom of the heat exchange cabinet 100, the wiring path also needs to be adjusted.

[0088] Regardless of the installation configuration, the electrical control component 500 is connected to a first mating terminal, meaning the electrical control component 500 is encapsulated within the air supply cabinet 200 and forms an external connection node through the first mating terminal. The detection head 610, cable 620, and second mating terminal form the detection component 600. The detection head 610 is installed in the area to be monitored within the heat exchange cabinet 100, such as the heat exchanger surface or airflow channel, and extends outwards via the first cable 620. After the heat exchange cabinet 100 and air supply cabinet 200 are installed, the end containing the second terminal 6252 of the cable 620 is passed through the adjacent side wall of the heat exchange cabinet 100 and air supply cabinet 200, and then extends into the air supply cabinet 200. The electrical connection between the heat exchange cabinet 100 and the electrical control component 500 is achieved through a detachable connection between the first and second mating terminals. In this embodiment, by allowing the second docking terminal and part of the cable 620 to pass through different sides of the heat exchange cabinet 100 in different installation states, the routing path of the cable 620 is shortened and the bending of the cable 620 is reduced.

[0089] The first mating terminal refers to the electrical connection interface fixed on the electronic control component 500, which can be implemented using a slot or snap-fit ​​contact, and is used to establish a standardized signal transmission channel with the detection component 600. The detection head 610 is a sensor used to collect temperature or pressure data, which can be implemented using a thermistor or piezoelectric element. The detection head 610 can monitor the internal status of the heat exchange cabinet 100 in real time. The cable 620 is the cable connecting the detection head 610 and the second mating terminal, which can be implemented using shielded twisted-pair cable or flexible ribbon cable. The cable 620 transmits the detection signal directionally to the electronic control component 500 through the first and second mating terminals. The second mating terminal is a plug-in component that matches the first mating terminal, which can be implemented using a spring pin or magnetic contact, and is used to achieve quick separation and connection between the detection component 600 and the electronic control component 500.

[0090] In practical applications, the electrical control component 500 can be set in the center or close to one side wall of the air supply cabinet 200; the wiring path for each installation state is explained below with the electrical control component 500 close to the left side wall of the air supply cabinet 200 as an example.

[0091] In the first installation state, the heat exchange cabinet 100 and the air supply cabinet 200 are divided into a first example and a second example based on their left-right positional relationship; in the second installation state, the heat exchange cabinet 100 and the air supply cabinet 200 are divided into a third example and a fourth example based on their vertical positional relationship.

[0092] In the first example, such as Figure 1 and Figure 2As shown, the air supply cabinet 200 is located on the right side of the heat exchange cabinet 100. The right side wall of the heat exchange cabinet 100 has a first cable outlet, and the top of the air supply cabinet 200 has a first cable passage. The cable 620 passes through the first cable outlet and the first cable passage to extend into the air supply cabinet 200. In the first example, by opening the first cable passage at the top of the air supply cabinet 200, the cable 620 bypasses the electrical control assembly 500 from the top of the heat exchange cabinet 100, and the connection point of the first and second mating terminals is located inside the air supply cabinet 200.

[0093] Of course, in other implementations, the first cable routing port can also be set on the left side wall of the heat exchange cabinet 100 and below the electrical control component 500, thereby further shortening the cable routing path and making the cable 620 layout simpler.

[0094] In the second example, such as Figure 3 and Figure 4 As shown, the air supply cabinet 200 is located on the left side of the heat exchange cabinet 100. The left side wall of the heat exchange cabinet 100 has a second cable outlet, and the right side wall of the air supply cabinet 200 has a second cable passage. The cable 620 passes through the second cable outlet and the second cable passage to extend into the air supply cabinet 200.

[0095] In the third example, such as Figure 5 , Figure 6 and Figure 9 As shown, the fan cabinet 200 is located at the top of the heat exchange cabinet 100. The cable 620 can pass through the first connection port 110 and the air inlet 210 and extend into the heat exchange cabinet 100 without the need for a separate cable routing structure.

[0096] In the fourth example, such as Figures 7 to 9 As shown, the air supply cabinet 200 is located at the bottom of the heat exchange cabinet 100. The cable 620 can pass through the second connection port 120 and the air inlet 210 and extend into the heat exchange cabinet 100 without the need for a separate cable passage structure.

[0097] Of course, in practical applications, the locations of the cable outlet and cable passage can be designed according to the location of the electrical control component 500. The cable outlet and cable passage can be formed using knockout holes. The assembly configuration is determined based on the installation space, and the breakable plate at the knockout hole is removed to create the cable outlet and cable passage. To prevent the cable 620 from becoming loose, some fixing points can be designed inside the heat exchanger cabinet 100 or the air supply cabinet 200.

[0098] For example, the cables 620 of multiple detection heads 610 are bundled into a single wire harness. Inside the heat exchange cabinet 100, the bundled wire harness can be secured to the pipes of the heat exchange component 810 using cable ties to form a fixing point. This fixing point is applicable to the first, second, third, and fourth examples described above. Alternatively, a fixing point can be designed near both the left and right ends of the mounting plate 830 connected to the heat exchange component 810. In the first example, the wire harness can be secured to the fixing point near the right end of the mounting plate 830 using cable ties; in the second example, it can be secured to the fixing point near the left end of the mounting plate 830 using cable ties. Inside the blower cabinet 200, holes can be drilled in the casing of the fan 820 to form fixing points. In the third and fourth examples, cable ties can be passed through the fixing points on the casing and used to bundle the wire harness.

[0099] Understandably, the location of the fixing point is not limited to this, but can be fixed to certain components inside the heat exchanger cabinet 100 or the air supply cabinet 200 according to the actual wiring path.

[0100] Based on the fourth example above, as previously explained, a water collection tray 300 is provided at the first connection port 110 of the heat exchange cabinet 100. The water collection tray 300 collects the condensate generated on the side of the first connection port 110, preventing liquid from contacting electrical components. Figures 7 to 10 As shown, a cable passage 410 can be provided in the water receiving pan 300 or the heat exchange cabinet 100 for the cable 620 to pass through. The cable 620 that electrically connects the heat exchange cabinet 100 and the air supply cabinet 200 may include a first segment 621, a second segment 622, and a third segment 623 connected in sequence. The first segment 621 is located above the water receiving pan 300, and the third segment 623 passes through the cable passage 410. The end where the second segment 622 and the third segment 623 are connected is higher than the end where the second segment 622 and the first segment 621 are connected, forming a natural drainage slope. By bending the cable 620 into a three-segment cable layout, a water return bend structure is formed through the physical structure, so that the condensate on the cable 620 flows through the second segment 622 to the first segment 621, thereby collecting and dripping into the water receiving pan 300 in the first segment 621, preventing the condensate from flowing to the electrical control component 500 with the cable 620, and reducing the risk of short circuit in the electrical control component 500.

[0101] Furthermore, the outer wall of the water receiving tray 300 is recessed, forming a cable passage 410 between the water receiving tray 300 and the inner wall of the heat exchange cabinet 100, thus constraining the routing path of the cable 620. The water receiving tray 300 has a first limiting hole 310 and a second limiting hole 320, with the second limiting hole 320 communicating with the cable passage 410. The portion of the cable 620 passing through the first limiting hole 310 is the first segment 621, and the portion between the first limiting hole 310 and the second limiting hole 320 is the second segment 622. By making the lower edge of the second limiting hole 320 higher than the upper edge of the first limiting hole 310 to form a height difference barrier, and by making the second segment 622 form an inclined structure, the cable 620 passes through the first limiting hole 310. The portion of the cable 620 with two limiting holes 320 located in the cable passage 410 is the third segment 623. By setting the first limiting hole 310 and the second limiting hole 320, the cable 620 is fixed and its direction is controlled in segments. The cable 620 passes through the first limiting hole 310, the second limiting hole 320 and the cable passage 410 in sequence to form the above-mentioned water trap structure, which effectively blocks the flow of condensate water to the electrical control component 500 with the cable 620; and prevents the movement of the line during subsequent use, keeping the water trap structure stable and effective.

[0102] In some embodiments, such as Figure 9 , Figure 11 and Figure 12 As shown, the air supply cabinet 200 has a housing 230 that divides the interior of the air supply cabinet 200 into a first cavity 241 and a second cavity 242. The first cavity 241 is connected to the air inlet 210, and the second cavity 242 houses the electrical control component 500. The heat exchange cabinet 100 is electrically connected to the electrical control component 500 via a second cable 620. The housing 230 has a cable tray connecting the first cavity 241 and the second cavity 242. The second cable 620 passes through the cable tray and is sealed to the wall of the cable tray. When a vortex fan 820 is used in the air supply cabinet 200, the air inlet of the vortex fan 820 is connected to the first cavity, so that the air that has been heated by the heat exchange component 810 enters the first cavity through the air inlet 210, and then passes through the fan 820 and the air outlet 220. The second chamber, isolated by the housing 230, can isolate the electronic control component 500 from the airflow environment, preventing condensation from forming on the electronic control component 500 or guiding the condensation flow to the electronic control component 500 through the condensation channel.

[0103] The housing 230 has a cable channel connecting the first cavity 241 and the second cavity 242. The cable 620 passes through the cable channel and is sealed to the channel wall. The cable channel refers to the cable passage that runs through the housing 230, which can be implemented using a U-shaped groove or a round hole structure. The cable channel provides a path for the cable 620 to be routed across the cavities. The sealed connection refers to the sealing and fixing method between the cable 620 and the cable channel, which can be implemented using a cable sleeve or injection molding process, thereby preventing condensate, cold air, and dust from entering the second cavity 242 and affecting the electronic control component 500.

[0104] Furthermore, the cable trays can be divided into two groups based on their installation location, such as... Figure 9 , Figure 11 and Figure 12 As shown, the cable tray located on the horizontal side of the housing 230 is defined as the first cable tray 2311, and the cable tray located on the side of the housing 230 facing the air inlet 210 is defined as the second cable tray 2312. When the air handling unit is in the first installation state, the cable 620 passes laterally into the electrical control cavity through the first cable tray 2311. At this time, the second cable tray 2312 is completely sealed by the sealant to prevent airflow from the air inlet 210 side from entering the electrical control cavity through the unused slot. When the air handling unit is in the second installation state, the cable 620 passes longitudinally into the electrical control cavity through the second cable tray 2312, and the first cable tray 2311 is sealed by the sealant to prevent foreign objects on the horizontal side from entering the equipment through the unused slot. By dynamically selecting the cable 620 path and closing redundant channels, different routing paths are selected under different installation directions, reducing cable length and avoiding cable crossing and tangling.

[0105] Specifically, rubber stoppers or foam can be used to achieve this, and the stoppers are embedded into the groove through an interference fit to form an airtight barrier.

[0106] In some embodiments, such as Figure 9 , Figure 11 and Figure 12 As shown, cable 620 includes a cable body 624 and an adapter 625. The cable body 624 refers to an independently arranged cable unit. The adapter 625 includes a first terminal 6251 and multiple second terminals 6252, all of which are electrically connected to the first terminal 6251. One end of each cable body 624 is located in the heat exchange cabinet 100, and the other end is provided with a third terminal 626. The third terminal 626 is detachably connected to the corresponding second terminal 6252. The electrical control component 500 is connected to a fourth terminal 520, which is detachably connected to the first terminal 6251. Detachable connection means that physical contact and electrical conduction between terminals are achieved by plugging, snapping, or threading. Specifically, a standardized plug and socket combination can be used.

[0107] During installation, the third terminals 626 of multiple cable bodies 624 are connected to the corresponding second terminals 6252 of the adapter 625, forming a branched wiring structure. The first terminal 6251 of the adapter 625 is connected to the electrical control component 500 via the fourth terminal 520. When it is necessary to switch the installation state, only the fourth terminal 520 and the first terminal 6251 need to be separated, the cable body 624 can be adjusted, and then reconnected without rearranging the entire wiring. For example, in the horizontal installation state, the cable body 624 can extend horizontally along the side wall of the heat exchange cabinet 100; in the vertical installation state, the cable body 624 can be arranged vertically along the top of the heat exchange cabinet 100. The adapter 625, as an intermediate hub, enables rapid reconfiguration of the wiring through standardized interfaces while maintaining the stability of the electrical connection.

[0108] This embodiment centrally manages multiple cables 620 through an adapter 625, avoiding installation chaos caused by scattered cables. It allows for the removal of only the faulty cable during maintenance without affecting the overall cabling structure, reducing the complexity of maintenance operations.

[0109] Based on the above embodiments, such as Figure 9 , Figure 11 and Figure 12 As shown, the cable body 624 can pass through the cable tray, so that the connection between the first terminal 6251 and the fourth terminal 520, and the connection between the second terminal 6252 and the third terminal 626 are all achieved in the second cavity; alternatively, the connection between the first terminal 6251 and the fourth terminal 520 can be achieved in the second cavity, with the portion connecting the first terminal 6251 and the second terminal 6252 passing through the cable tray, and the connection between the second terminal 6252 and the third terminal 626 being achieved in the third cavity; alternatively, the structure connecting the fourth terminal 520 and the electrical control component 500 can pass through the cable tray, so that the connection between the first terminal 6251 and the fourth terminal 520, and the connection between the second terminal 6252 and the third terminal 626 are all achieved in the first cavity; this application does not limit this.

[0110] In cases where the docking of the first terminal 6251 and the fourth terminal 520, and the docking of the second terminal 6252 and the third terminal 626 are both achieved in the second chamber, a retainer can be provided in the second chamber to fix the fourth terminal 520 on the retainer, while the guide body is limited by the wire groove, so that the first terminal 6251 and the second terminal 6252 of the adapter 625 are both kept in a relatively stable state, reducing the risk of the first terminal 6251 and the fourth terminal 520 becoming loose, and the second terminal 6252 and the third terminal 626 becoming loose.

[0111] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
