[0002] In air conditioning units, the electrical control box houses multiple electrical components. These components are connected to components such as the fan and compressor via cables to control their operation. Refrigerant leaks can occur during operation. If the leaked refrigerant is flammable, it could ignite or even explode if it enters the control box. Furthermore, gaps exist between the control box and the cables in some technologies, allowing refrigerant to pass through and potentially cause a fire or explosion. Utility Model Content

The cable guide tube is used for cable passage, and the cable guide tube includes a curved section and a straight section, the angle between the curved section and the straight section being less than or equal to 90°.

[0005] In the electrical control box assembly of this invention, by setting the angle between the bent and straight sections of the conduit to less than or equal to 90°, the cable can form a self-locking seal when passing through the conduit. This significantly reduces the gap between the cable and the conduit, effectively reducing the probability of leaked refrigerant entering the interior of the electrical control box assembly through this gap, thereby reducing the risk of fire or explosion and enhancing the sealing and safety of the electrical control box assembly. Furthermore, because the conduit fits tightly against the cable hole, the gap between the cable hole and the conduit is significantly reduced, effectively preventing refrigerant from entering the interior of the electrical control box assembly through the cable hole, thus reducing the risk of fire or explosion and enhancing the sealing and safety of the electrical control box assembly.

[0009] In some embodiments, the clamping part includes a flat plate and a first folded edge, the first folded edge being connected to one edge of the flat plate, the first folded edge being inclined relative to the flat plate in a direction away from the cable guide tube, and the angle between the first folded edge and the flat plate being greater than 0° and less than 90°.

[0010] In some embodiments, the clamping part includes a flat plate and a second folded edge, the second folded edge being connected to one edge of the flat plate, the second folded edge being inclined relative to the flat plate toward the cable guide tube, the second folded edge abutting against the outer surface of the cable guide tube, and the angle between the second folded edge and the flat plate being greater than or equal to 60° and less than or equal to 120°.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The electrical control box assembly 100 of this utility model includes a box body 10 and a cable conduit 20. The box body 10 is provided with a cable passage hole 11; the cable conduit 20 passes through the cable passage hole 11 and is tightly fitted to the cable passage hole 11. The cable conduit 20 is used for cable passage. The cable conduit 20 includes a bent section 21 and a straight section 22. The angle F between the bent section 21 and the straight section 22 is less than or equal to 90°.

[0034] In the electrical control box assembly 100 of this embodiment, by setting the angle F between the bent section 21 and the straight section 22 of the conduit 20 to less than or equal to 90°, the cable can form a self-locking seal when passing through the conduit 20. This significantly reduces the gap between the cable and the conduit 20, thereby effectively reducing the probability of leaked refrigerant entering the interior of the electrical control box assembly 100 through the gap between the cable and the conduit 20, thus reducing the risk of fire or explosion and enhancing the sealing and safety of the electrical control box assembly 100. Furthermore, since the conduit 20 is tightly fitted to the through hole 11, the gap between the through hole 11 and the conduit 20 is significantly reduced, effectively preventing refrigerant from entering the interior of the electrical control box assembly 100 through the through hole 11, thereby reducing the risk of fire or explosion and enhancing the sealing and safety of the electrical control box assembly 100.

[0035] Specifically, the box body 10 serves as the supporting foundation for the electrical control box assembly 100. The box body 10 can be used to house and protect the internal electrical components. The shape of the box body 10 can be regular, such as a cuboid or a cylinder, or it can be irregular. The box body 10 can be made of heat-resistant and flame-retardant materials to prevent the spread of fire in the event of a fire in the electrical control box assembly 100.

[0036] The cable passage 11 serves as a channel for cables to enter and exit the electrical control box. The cable conduit 20 provides physical protection for the cables passing through it, preventing damage from external mechanical damage, friction, or impact. The cable conduit 20 guides the cables through the cable passage 11 in an orderly manner, preventing multiple cables from becoming tangled and facilitating maintenance and management.

[0037] The conduit 20 can be made of rigid materials such as hard plastic or metal, or it can be made of flexible materials such as soft plastic or rubber. The number of conduits 20 can be one or more to meet different needs. The number of conduits 20 and conduits 11 can correspond one-to-one or not. For example, the box body 10 has four spaced conduits 11. The four conduits 20 are arranged one-to-one with the four conduits 11. As another example, the box body 10 has two spaced conduits 11. The four conduits 20 are evenly distributed in the two conduits 11.

[0038] The conduit 20 can be fixed to the cable passage hole 11 by means of guide nesting, sealant bonding, or by welding, hot-melt connection, or integral molding to achieve a tight fit with the cable passage hole 11. The conduit 20 has a cable passage for the cable to pass through. The cable can be used to connect electrical components inside the electrical control box assembly 100 to external electrical components, such as fans and compressors.

[0039] The curved section 21 and the straight section 22 can be formed during the manufacturing process, or they can be formed by applying external force to the conduit 20. For example, for a conduit 20 made of a rigid material, the curved section 21 and the straight section 22 can be formed during the manufacturing process. As another example, for a conduit 20 made of a flexible material, the curved section 21 and the straight section 22 can be formed by folding the conduit 20 in half with external force.

[0040] The curved section 21 may be located on the side of the wire-through hole 11 facing the outside of the electrical control box assembly 100. The straight section 22 may be connected to the wire-through hole 11, or at least partially located inside the electrical control box assembly 100. The curved section 21 may have an opening. For a curved section 21 with a curved central axis, the angle F between the curved section 21 and the straight section 22 may be the angle between the normal to the plane containing the opening and the central axis of the straight section 22. For a curved section 21 with a straight central axis, the angle F between the curved section 21 and the straight section 22 may be the angle formed between the central axis of the curved section 21 and the central axis of the straight section 22. The angle range between the curved section 21 and the straight section 22 can be [0°, 90°], [30°, 90°], [45°, 75°], [45°, 60°], [60°, 90°], [0°, 45°], etc.

[0041] When the angle between the curved section 21 and the straight section 22 is 90°, the central axis of the curved section 21 can be a straight line, and the central axis of the curved section 21 can be perpendicular to the central axis of the straight section 22. The curved section 21 and the straight section 22 can form a bend structure similar to an "L". When the angle between the curved section 21 and the straight section 22 is 0°, the normal to the plane containing the opening of the curved section 21 is parallel to the central axis of the straight section 22. The curved section 21 and the straight section 22 can form a bend structure similar to a "J".

[0042] It is understandable that when the angle between the curved section 21 and the straight section 22 is 90°, the gap between the cable in the conduit 20 and the conduit 20 is smaller when the angle between the curved section 21 and the straight section 22 is 0° compared to when the angle between the curved section 21 and the straight section 22 is 0°. This makes it more difficult for the refrigerant to enter the electrical control box assembly 100 through the gap between the cable and the conduit 20, resulting in better sealing performance of the electrical control box assembly 100.

[0043] Please see Figure 4 and Figure 5 In some embodiments, the electrical control box assembly 100 further includes an isolator 30, at least a portion of which is located below the box body 10, with the wire hole 11 extending toward the isolator 30.

[0044] Thus, in the event of a fire caused by a malfunction inside the electrical control box assembly 100, the isolator 30 can absorb the burning materials generated by the fire or block the flames, thereby preventing the fire from spreading to the refrigerant leakage area below the electrical control box and thus avoiding contact between the fire and the refrigerant, reducing the risk of explosion. At the same time, the isolator 30 can also reduce the probability of refrigerant entering the electrical control box assembly 100 from below through the wiring hole 11, thereby improving the safety of the electrical control box assembly 100.

[0045] Specifically, the shape of the spacer 30 can be plate-shaped, disc-shaped, block-shaped, etc., for example, the spacer 30 can be a spacer plate, spacer disc, spacer block, etc. The spacer 30 can be made of materials such as metal, heat-resistant and flame-retardant plastic, etc. The spacer 30 can be connected to the box body 10. For example, the spacer 30 can be connected to the box body 10 by bolts, welding, etc. The spacer 30 can also be set independently. For example, the spacer 30 has a support column and a disc set on top of the support column. The disc is located below the box body 10.

[0046] The extension of the wire hole 11 toward the isolator 30 means that the central axis of the wire hole 11 passes through the plane where the isolator 30 is located.

[0047] Please see Figure 4 and Figure 6 In some embodiments, the conduit 20 is a flexible hose, and the separator 30 abuts against the outer surface 23 of the conduit 20 to form a curved section 21 and a straight section 22 in the conduit 20.

[0048] Thus, during assembly, the insulating element 30 only needs to abut against the outer surface 23 of the conduit 20 to form a bent section 21 and a straight section 22 in the conduit 20, thereby achieving a sealed and self-locking effect for the cable as it passes through the conduit 20. Compared to directly machining the bent section 21 and the straight section 22, using the insulating element 30 in conjunction with the flexible conduit is less costly and reduces assembly complexity.

[0049] Furthermore, since at least part of the isolator 30 is located below the box body 10, the wiring hole 11 extends towards the isolator 30. Therefore, leaked refrigerant can easily reach the wiring hole 11 from below. When the electrical control box assembly 100 is positioned above the refrigerant leak area, the probability of leaked refrigerant entering the electrical control box assembly 100 is relatively high. By providing the isolator 30, in the event of a fire inside the wiring box assembly, the combustibles inside the wiring box assembly and the combustibles generated when the hose burns can be contained by the isolator 30. This prevents the fire from spreading to the refrigerant leak area below the electrical control box assembly 100, thereby avoiding contact between the fire and the refrigerant and reducing the risk of explosion.

[0050] Specifically, the conduit 20 can be a flexible hose made of soft plastic or rubber. Compared to conduits made of rigid plastic or metal, flexible hoses are more likely to burn and produce combustibles in the event of a fire inside the junction box assembly. Therefore, by providing the isolator 30, it is possible to prevent these combustibles from falling into the refrigerant leakage area below the electrical control box assembly 100.

[0051] The flexible conduit is normally straight and hangs downwards in the direction of gravity when there is no external force. Since the isolator 30 abuts against the outer surface 23 of the conduit 20, the isolator 30 can apply force to the outer surface 23 of the conduit 20, so that the conduit 20 is pressed from a straight state to a folded state, thereby achieving a self-locking seal for the cable inside the conduit 20.

[0052] Please see Figure 4 and Figure 6 In some embodiments, the isolation member 30 includes a connecting portion 31 and a clamping portion 32 connected at an angle to the connecting portion 31. The connecting portion 31 is connected to the box body 10, and the clamping portion 32 abuts against the outer surface 23 of the cable conduit 20 so that the cable conduit 20 forms a curved section 21 and a straight section 22.

[0053] Thus, since the clamping part 32 abuts against the outer surface of the conduit 20 and is angularly connected to the connecting part 31, this design can adapt to different wiring angle requirements, ensuring a smooth transition of the conduit 20 between the curved section 21 and the straight section 22. Simultaneously, during assembly, simply connecting the connecting part 31 to the box body 10 simultaneously achieves both fixing and guiding of the conduit 20, reducing assembly complexity.

[0054] Specifically, the angle between the connecting part 31 and the clamping part 32 can be an acute angle, a right angle, or an obtuse angle. The connecting part 31 and the box body 10 can be connected by detachable means such as threaded connection or snap-fit, or by non-detachable means such as welding, bonding, or riveting. For example, the connecting part 31 has multiple threaded holes, and the box body 10 has multiple corresponding threaded holes. Bolts are used to achieve the connection between the connecting part 31 and the box body 10.

[0055] The connecting part 31 can be a plate, lug, or other structure connected to a section of the clamping part 32. For example, the connecting part 31 can be a connecting plate or a connecting lug. The clamping part 32 can be a plate, disc, or other structure connected to the connecting part 31. For example, the clamping part 32 can be a clamping plate or a clamping disc. The connecting part 31 and the clamping part 32 can be integrally molded. Integral molded parts are structurally more stable because there is no seam between the connecting part 31 and the clamping part 32, reducing structural weaknesses caused by improper connection. For example, injection molding or pressure molding technology can be used to form the materials of the connecting part 31 and the clamping part 32 into the required shape in a single molding process.

[0056] The connecting part 31 and the clamping part 32 can also be separately molded structures. Separate molding allows the connecting part 31 and the clamping part 32 to be manufactured independently, which can reduce manufacturing costs and processing difficulty. For example, the connecting part 31 and the clamping part 32 can be manufactured separately, and then adhesives, screws, rivets or other mechanical connection methods can be used to fix the connecting part 31 and the clamping part 32.

[0057] During assembly, the connecting part 31 can be connected to the box body 10. At this time, the clamping part 32 can directly abut against the outer surface 23 of the cable conduit 20 to apply force to the cable conduit 20 so that the cable conduit 20 forms a curved section 21 and a straight section 22.

[0058] Please see Figure 3 In some embodiments, the clamping part 32 includes a flat plate 320 and a first folded edge 321, the first folded edge 321 being connected to one edge of the flat plate 320, the first folded edge 321 being inclined relative to the flat plate 320 in a direction away from the cable conduit 20, and the angle B between the first folded edge 321 and the flat plate 320 being greater than 0° and less than 90°.

[0059] Thus, the inclined design of the first folded edge 321 allows it to function as a guide structure, making the installation and maintenance of the cable conduit 20 more convenient. Within the angle range between the flat plate 320 and the first folded edge 321 (greater than 0° and less than 90°), the contact between the cable conduit 20 and the clamping part 32 changes from line contact to surface contact. This surface contact reduces the frictional resistance between the cable conduit 20 and the clamping part 32 during assembly, thereby reducing assembly complexity and improving assembly efficiency.

[0060] Specifically, the plate 320 can be connected to the connecting part 31. The first folded edge 321 can be connected to the edge of the plate 320 away from the connecting part 31. During assembly, the first folded edge 321 can contact the conduit 20 and provide a guiding function.

[0061] The angle B between the first folded edge 321 and the plate 320 refers to the angle between the plane of the plate 320 close to the conduit 20 and the plane adjacent to the first folded edge 321. The angle B between the first folded edge 321 and the plate 320 can be in the range of (0°, 90°), [30°, 90°), [45°, 75°], [45°, 60°], [60°, 90°), (0°, 45°], etc. The angle B between the first folded edge 321 and the plate 320 can be 30°, 45°, 60°, 75°, 85°, etc.

[0062] Please see Figure 7 In some embodiments, the clamping part 32 includes a flat plate 320 and a second folded edge 322. The second folded edge 322 is connected to one edge of the flat plate 320. The second folded edge 322 is inclined relative to the flat plate 320 toward the cable conduit 20. The second folded edge 322 abuts against the outer surface 23 of the cable conduit 20. The angle C between the second folded edge 322 and the flat plate 320 is greater than or equal to 60° and less than or equal to 120°.

[0063] Thus, the second fold 322 allows the bent section 21 of the conduit 20 to be closer to the straight section 22, which makes the gap between the cable and the conduit 20 smaller, thereby further reducing the probability that leaked refrigerant will enter the electrical control box assembly 100 through the gap between the conduit 20 and the cable.

[0064] Specifically, the second folded edge 322 can be connected to the edge of the plate 320 on the side away from the connecting part 31. Both the second folded edge 322 and the plate 320 can abut against the outer surface 23 of the conduit 20, so that the conduit 20 forms a curved section 21 and a straight section 22.

[0065] The angle C between the second folded edge 322 and the plate 320 refers to the angle between the plane of the plate 320 close to the conduit 20 and the plane adjacent to the second folded edge 322. The angle C between the second folded edge 322 and the plate 320 can be in the range of [60°, 120°], [75°, 120°], [80°, 115°], [90°, 120°], [60°, 100°], etc.

[0066] Please see Figure 4 and Figure 6 In some embodiments, the clamping part 32 includes a flat plate 320 and a third folded edge 323, and the flat plate 320 and the connecting part 31 are connected by the third folded edge 323.

[0067] Thus, the connection between the plate 320 and the connecting part 31 via the third fold 323 provides an additional support point, thereby enhancing the overall structural strength of the clamping part 32. Since the plate 320 abuts against the conduit 20, the conduit 20 and the cable within it exert pressure on the plate 320. The third fold 323 disperses this pressure, reducing deformation of the plate 320 due to excessive local pressure, thereby decreasing the likelihood of increased gap between the conduit 20 and the cable caused by plate 320 deformation.

[0068] Specifically, one end of the third fold 323 is connected to the flat plate 320, and the other end of the third fold 323 is connected to the connecting part 31. The shape of the third fold 323 can be a straight line, a curve, or other shapes. The connecting part 31 and the third fold 323 can be an integrally molded structure. Integral molded parts are structurally more stable because there is no seam between the connecting part 31 and the third fold 323, reducing structural weaknesses caused by improper connection. For example, injection molding or pressure molding technology can be used to form the material of the connecting part 31 and the third fold 323 into the desired shape in a one-time molding process.

[0069] The connecting part 31 and the third folded edge 323 can also be separately molded structures. Separate molding allows the connecting part 31 and the third folded edge 323 to be manufactured independently, which can reduce manufacturing costs and processing difficulty. For example, the connecting part 31 and the third folded edge 323 can be manufactured separately, and then adhesives, screws, rivets or other mechanical connection methods can be used to fix the connecting part 31 and the third folded edge 323.

[0070] Please see Figure 8 In some embodiments, the box body 10 includes a bottom plate 12 and a surrounding plate 13 connected to the bottom plate 12. The surrounding plate 13 and the bottom plate 12 form an opening 101. A connecting part 31 covers the opening 101. The connecting part 31, the surrounding plate 13 and the bottom plate 12 together form a receiving cavity 102.

[0071] Thus, during assembly, the isolating member 30 not only forms a curved section 21 and a straight section 22 in the conduit 20 through the clamping part 32 to achieve a self-locking seal for the cable as it passes through the conduit 20, but also, by covering the opening 101 with the connecting part 31, works with the surrounding plate 13 and the bottom plate 12 to form a receiving cavity 102 to accommodate the components inside the electrical control box assembly 100. This reduces the complexity of assembly, reduces the use of additional parts, and lowers the manufacturing cost of the electrical control box assembly 100.

[0072] Specifically, the base plate 12 can be connected to the bottom of the surrounding plate 13 in the vertical direction. The base plate 12 and the surrounding plate 13 can be connected by detachable means such as threaded connection or snap-fit, or by non-detachable means such as welding, bonding, or riveting. For example, the base plate 12 has multiple buckles, and the surrounding plate 13 has multiple corresponding locking holes. The connection between the base plate 12 and the surrounding plate 13 is achieved by the cooperation of the buckles and locking holes.

[0073] After the base plate 12 and the surrounding plate 13 are connected, an opening 101 can be formed. The shape of the opening 101 can be a regular shape, such as a square or a circle, or it can be an irregular shape. The connecting part 31 can be a plate-like structure, for example, the connecting part 31 can be a connecting plate, and the edge of the connecting plate can be connected around the opening 101 to cover the opening 101.

[0074] The receiving cavity 102 can be used to house electrical components inside the electrical control box assembly 100. The receiving cavity 102 can provide physical protection for the electrical components inside the electrical control box assembly 100, preventing damage to the components from the external environment. The receiving cavity 102 can be designed in different shapes and sizes to accommodate different types and numbers of electrical components.

[0075] Please see Figure 5 and Figure 8In some embodiments, the base plate 12 is provided with a wire passage hole 11, and the clamping part 32 is located below the box body 10, with the wire passage hole 11 extending toward the clamping part 32.

[0076] Thus, the clamping part 32 not only enables the cable conduit 20 to form a curved section 21 and a straight section 22 to achieve a self-locking seal during the cable passing through the cable conduit 20, but also enables it to absorb the burning material generated when the electrical control box assembly 100 catches fire or block the flame.

[0077] Specifically, the cable guide hole 11 can be a through hole penetrating the base plate 12. The clamping part 32 can be parallel to the base plate 12, which can provide uniform support for the cable guide tube 20, helping to maintain the stability of the cable guide tube 20 in the clamping part 32 and reduce displacement caused by vibration. The clamping part 32 can also be inclined relative to the base plate 12, for example, the clamping part 32 is inclined towards the base plate 12, which can make the bending range of the cable guide tube 20 greater, thereby making the gap between the cable guide tube 20 and the cable smaller.
