Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an electrical control box, an electrical control box assembly, and an air conditioner. Background Technology

[0002] The electrical control box assembly of the outdoor unit of the air conditioner is responsible for regulating the operating status of the entire air conditioning system; the electrical control box assembly has high requirements for sealing performance, and needs to prevent moisture, dust and other contaminants from entering.

[0003] Related technologies rely solely on mechanical assembly for sealing, which cannot achieve high-precision sealing and will still leave some gaps that cannot be sealed. Other technologies, in order to improve the sealing effect, use adhesives with good adhesion, sealing properties, water resistance, and corrosion resistance for potting and sealing. At the same time, the potting can also play a certain role in insulation and shock absorption.

[0004] However, the related technologies provide electrical control boxes for potting that are difficult to improve potting efficiency and are difficult to achieve a good potting seal on both sides of the circuit board assembled in the electrical control box. Moreover, before potting or before the potting adhesive cures, it is difficult to improve the stability of the circuit board assembled in the electrical control box. The circuit board is prone to shifting in the electrical control box, resulting in poor potting seal. The circuit board may even accidentally detach from the electrical control box during potting and fall or get damaged. Utility Model Content

[0005] The problems solved by this utility model include: how to improve the potting efficiency and glue penetration rate of the electrical control box, and how to ensure that both sides of the circuit board assembled in the electrical control box form a good potting and sealing effect; how to improve the stability of the circuit board assembled in the electrical control box before potting or before the glue cures, so as to improve the problem of poor potting and sealing effect caused by the displacement of the circuit board in the electrical control box, and to improve the problem of the circuit board accidentally falling and being damaged due to detachment from the electrical control box; how to control the amount of glue used in potting, while ensuring a good potting and sealing effect and controlling costs, and how to improve the problem of glue overflow.

[0006] To solve the above problems, this utility model provides an electrical control box, which includes:

[0007] The box body includes a support part and a first surrounding rib connected to the support part, the first surrounding rib enclosing an installation space;

[0008] Supporting ribs, which are connected to at least one of the supporting portion and the first surrounding ribs; and,

[0009] The clip connects to the first reinforcing bar; among which...

[0010] The mounting space is used to assemble the circuit board, the support rib is used to support the circuit board so that a filling cavity for filling sealant is formed between the circuit board and the support. The first rib can form an overflow gap between itself and the circuit board that communicates with the filling cavity. The buckle is used to cooperate with the circuit board to prevent the circuit board from falling out of the mounting space.

[0011] By using support ribs to support the circuit board assembled in the installation space, a filling cavity for filling sealant is formed between the circuit board and the support of the control box, thus achieving a good potting and sealing effect on the lower surface of the circuit board facing the support. By using the overflow gap connected to the filling cavity to allow the sealant to overflow, a good potting and sealing effect can also be achieved on the upper surface of the circuit board away from the support.

[0012] By using clips to engage with the circuit board assembled in the installation space, the stability of the circuit board assembly in the installation space can be improved. This can improve the problem of the circuit board shifting relative to the control box before potting or before the potting adhesive cures, thereby ensuring a good potting and sealing effect, and can also improve the problem of the circuit board accidentally detaching from the control box and falling or being damaged.

[0013] In an optional embodiment, the support includes a support body and a boss connected to the support body, and a first rib is connected to at least one of the support body and the boss. The boss is located within the mounting space. When the circuit board is assembled in the mounting space, the gap between the boss and the circuit board is smaller than the gap between the support body and the circuit board.

[0014] Optimizing the height between the support and the circuit board mounted in the installation space reduces the gap between certain areas (i.e., the boss area) and the circuit board, effectively controlling the amount of adhesive used. This allows for saving adhesive while ensuring good potting and sealing effects, thereby reducing costs.

[0015] In an optional implementation, the height D of the boss protruding from the support body is 0.5-1.5 mm.

[0016] Optimizing the height difference between the boss and the support body can control the amount of glue used, ensure a good glue sealing effect, and ensure the structural strength of the support.

[0017] In an optional embodiment, the electrical control box further includes a limiting rib, which is connected to at least one of the first surrounding rib and the support portion, and is located on the side of the first surrounding rib facing the mounting space; when the circuit board is assembled in the mounting space, the limiting rib abuts against or is spaced apart from the circuit board.

[0018] By using the limiting ribs, it is possible to ensure that a suitable glue overflow gap is formed between the circuit board assembled in the installation space and the first surrounding rib. This facilitates a higher glue penetration rate during glue pouring, which is beneficial for improving the glue pouring and sealing efficiency. It also ensures that the circuit board can reliably achieve glue pouring and sealing on both sides facing the support and away from the support, thereby improving the sealing effect.

[0019] In an optional embodiment, the ratio of the height H1 of the first rib to the height H2 of the supporting rib is 2.000 to 8.000.

[0020] By adjusting the height ratio of the first and second reinforcing ribs, the amount of adhesive used can be significantly controlled, ensuring a good sealing effect while controlling costs.

[0021] In an optional embodiment, the box body further includes a second surrounding rib; the first surrounding rib is provided with a clearance opening, and the buckle is located at the clearance opening;

[0022] The second rib is connected to the first rib and the support part, and the second rib is located on the side of the first rib away from the installation space. The second rib encloses the glue-holding cavity, and the clearance opening connects the installation space and the glue-holding cavity.

[0023] By placing the latch at the clearance opening, it is possible for the latch to shift slightly when the circuit board is assembled into the mounting hole, thus preventing the latch from interfering with the assembly of the circuit board. After the circuit board is assembled, the latch can return to its original position to reliably engage with the circuit board, improving the problem of the circuit board easily shifting or coming out in the installation space. The addition of the second reinforcing rib can also prevent glue from leaking out of the control box from the clearance opening.

[0024] In an optional embodiment, the electrical control box further includes a first wiring section, which is connected to at least one of the support section, the first retaining rib, and the second retaining rib. The first wiring section is located outside the mounting space and is used to limit the position of the wires connecting the circuit board assembled in the mounting space. This arrangement can improve the problem of messy wiring.

[0025] In an optional embodiment, the support is provided with an assembly number, which is distributed on the side of the first reinforcing bar away from the installation space.

[0026] This setup allows for assembly processes such as wire insertion to be performed according to the assembly tag number during production, simplifying the wire insertion process and improving efficiency and assembly accuracy.

[0027] In an optional embodiment, the control box further includes a second wiring section, which is connected to at least one of the support section and the first reinforcing rib. The second wiring section is located outside the mounting space and is used to limit the position of the wires connecting the circuit board assembled in the mounting space. This arrangement can improve the problem of messy wiring.

[0028] This utility model also provides an electrical control box assembly, including: a circuit board and an electrical control box according to any of the foregoing embodiments; the circuit board is assembled in the installation space and supported by a support rib; and a buckle cooperates with the circuit board.

[0029] By using support ribs to support the circuit board, a filling cavity for filling sealant is formed between the circuit board and the support part of the control box, a good potting and sealing effect can be formed on the lower surface of the circuit board facing the support part. By using the overflow gap connected to the filling cavity to allow the sealant to overflow, a good potting and sealing effect can also be formed on the upper surface of the circuit board away from the support part.

[0030] By using clips to engage with the circuit board, the stability of the circuit board assembly in the installation space can be improved. This can improve the problem of the circuit board shifting relative to the control box before potting or before the potting adhesive cures, thereby ensuring a good potting and sealing effect. It can also improve the problem of the circuit board accidentally detaching from the control box and falling or being damaged.

[0031] In an optional embodiment, the ratio of the width H3 of the adhesive overflow gap to the height H4 of the circuit board is 0.625 to 1.875;

[0032] The ratio of the height H2 of the support rib to the height H4 of the circuit board is 1.250 to 3.125.

[0033] Optimizing the width of the glue overflow gap between the circuit board and the first reinforcing rib can increase the glue penetration rate during glue application, thereby ensuring that both the side of the circuit board facing the support and the side of the circuit board away from the support are effectively covered by sealant, thus ensuring a good glue sealing effect on both sides of the circuit board.

[0034] By controlling the height of the circuit board to match the height of the first rib and the support rib, it is possible to ensure that both the side of the circuit board facing the support and the side of the circuit board away from the support are effectively covered with sealant, thereby improving the sealing effect. At the same time, it is possible to control the amount of sealant used, thereby reducing the problems of sealant waste and increased costs.

[0035] In an optional embodiment, the distance between the support and the circuit board includes at least a first distance and a second distance, wherein the ratio of the first distance to the second distance is 0.556 to 0.943.

[0036] Optimizing the height between the support and the circuit board, so that the gap between some areas of the support and the circuit board is smaller than the gap between other areas of the support and the circuit board, can effectively control the amount of glue used, so as to save glue usage while ensuring good potting and sealing effect, thereby reducing costs.

[0037] In an optional embodiment, both the filling cavity and the overflow gap are filled with sealant, and the side of the circuit board away from the support is covered with sealant.

[0038] This ensures that both the side of the circuit board facing the support and the side of the circuit board away from the support are effectively covered by sealant, improving the sealing effect.

[0039] This utility model also provides an air conditioner, including an outdoor unit. The outdoor unit includes a housing, a partition, and an electrical control box assembled in any of the aforementioned embodiments, or an electrical control box assembly in any of the aforementioned embodiments. The partition is vertically disposed at the bottom of the housing, and the electrical control box is vertically attached to and disposed on the partition.

[0040] The air conditioner includes all the beneficial effects of the aforementioned control box or control box assembly, such as: improving the potting efficiency and glue penetration rate of the control box, ensuring a good potting and sealing effect on both sides of the circuit board assembled in the control box; improving the stability of the circuit board assembled in the control box before potting or before the glue cures, so as to improve the problem of poor potting and sealing effect caused by the circuit board shifting in the control box, and to improve the problem of the circuit board accidentally falling and being damaged due to accidental detachment from the control box; controlling the amount of glue used for potting, controlling costs while ensuring a good potting and sealing effect, and improving the problem of glue overflow.

Detailed Implementation

[0052] The related technology provides an air conditioner outdoor unit electrical control box assembly that uses potting sealant for waterproofing and dustproofing. However, the related technology provides an electrical control box for potting that is difficult to improve potting efficiency and is difficult to achieve a good potting seal on both sides of the circuit board mounted in the electrical control box. Moreover, before potting or before the potting adhesive cures, it is difficult to improve the stability of the circuit board mounted in the electrical control box. The circuit board is prone to shifting in the electrical control box, resulting in poor potting seal. The circuit board may even accidentally detach from the electrical control box during potting and fall or get damaged.

[0053] This embodiment provides an electrical control box assembly for an outdoor unit of an air conditioner, which includes an electrical control box and a circuit board mounted on the electrical control box; the electrical control box assembly can improve the above-mentioned problems.

[0054] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0055] The air conditioner in this embodiment includes an indoor unit and an outdoor unit. The indoor unit can refer to a wall-mounted unit or a floor-standing unit, and is not specifically limited here. The outdoor unit includes a casing, a partition, and an electrical control box assembly 010. Please refer to [reference needed]. Figure 1 and Figure 2 The electrical control box assembly 010 includes an electrical control box 100 and a circuit board 200 assembled in the electrical control box 100. The circuit board 200 is connected to other electrical components of the outdoor unit. A partition is vertically arranged at the bottom of the housing, and the electrical control box is vertically attached to and arranged on the partition.

[0056] The electrical control box 100 includes a box body 110, a support rib 141, and a buckle 142. The box body 110 includes a support portion 120 and a first surrounding rib 130 connected to the support portion 120. The first surrounding rib 130 encloses an installation space 131. The support rib 141 is connected to both the first surrounding rib 130 and the support portion 120. The buckle 142 is connected to the first surrounding rib 130. The circuit board 200 is assembled in the installation space 131 and supported by the support rib 141, so that a filling cavity for filling sealant is formed between the circuit board 200 and the support portion 120. An overflow gap 133 communicating with the filling cavity is formed between the first surrounding rib 130 and the circuit board 200. The buckle 142 engages with the circuit board 200 to prevent the circuit board 200 from detaching from the installation space 131.

[0057] The circuit board 200, which is mounted in the mounting space 131, is supported by the support rib 141, so that a filling cavity for filling sealant is formed between the circuit board 200 and the support portion 120 of the electrical control box 100. This can form a good potting and sealing effect on the lower surface of the circuit board 200 facing the support portion 120. The sealant overflows by using the overflow gap 133 that communicates with the filling cavity, which can ensure that a good potting and sealing effect can also be formed on the upper surface of the circuit board 200 away from the support portion 120.

[0058] Therefore, it can be seen that when the potting and sealing are completed, the filling cavity and overflow gap 133 in the electrical control box assembly 010 are filled with sealant, and the side of the circuit board 200 facing away from the support 120 is covered with sealant. The circuit board 200 is sealed and fixed by potting. In this way, it can be ensured that both the side of the circuit board 200 facing the support 120 and the side of the circuit board 200 facing away from the support 120 are effectively covered with sealant, improving the sealing effect. It should be noted that other electrical components of the outdoor unit are connected to the circuit board 200. For example, the electrical components are soldered or plugged into the circuit board 200 through connectors. The sealant covering the side of the circuit board 200 away from the support part 120 can also seal the connectors of the electrical components, thereby further improving the sealing effect of the electrical control box assembly 010. In this way, the setting of the box cover can also be reduced, that is, it is no longer necessary to connect the box cover to the electrical control box 100 to cover and seal the side of the circuit board 200 away from the support part 120. When the electrical control box assembly 010 fails and maintenance is required, the electrical components and the circuit board 200 cannot be disassembled. The electrical control box assembly 010 can be replaced as a whole for maintenance, which can reduce the maintenance difficulty of the electrical control box assembly 010 and improve maintenance efficiency.

[0059] By using the clip 142 to cooperate with the circuit board 200 assembled in the mounting space 131, the stability of the circuit board 200 assembled in the mounting space 131 can be improved. This can improve the problem of the circuit board 200 shifting relative to the control box 100 before potting or before the potting adhesive cures, thereby ensuring a good potting and sealing effect and improving the problem of the circuit board 200 accidentally detaching from the control box 100 and falling or being damaged.

[0060] Of course, in other embodiments, the support rib 141 may be connected to only one of the first surrounding rib 130 and the support portion 120, and the buckle 142 may be engaged with the circuit board 200; no specific limitation is made here.

[0061] It should be noted that the filling cavity is a portion of the space within the mounting space 131 after the circuit board 200 is assembled into the mounting space 131.

[0062] Furthermore, the control box 100 includes a plurality of support ribs 141, which are spaced apart along the inner sidewall of the first surrounding rib 130 to stably support the circuit board 200. The gaps between the spaced support ribs 141 connect the overflow gap 133 and the filling cavity, which helps to increase the glue penetration rate during glue pouring.

[0063] Please refer to Figure 3 and Figure 4 In this embodiment, the first rib 130 is provided with a clearance opening 132, and the buckle 142 is elastically fitted at the clearance opening 132. That is, the buckle 142 is elastically connected to the first rib 130 and located at the clearance opening 132. When the circuit board 200 is assembled in the mounting space 131, the circuit board 200 can abut against the buckle 142 so that the buckle 142 avoids the movement path of the circuit board 200. When the circuit board 200 is assembled in the mounting space 131, the buckle 142 can be reset under elastic action and engage with the circuit board 200. In this way, the ease of assembly of the circuit board 200 is ensured, and the reliability of the circuit board 200 assembled in the control box 100 is also ensured.

[0064] The buckle 142 can be elastically connected to the first rib 130 by using an elastic material to make the buckle 142, so that the buckle 142 is elastically connected to the first rib 130 by using the elasticity of the material itself, or by using an elastic element such as a spring sheet to connect the buckle 142 to the first rib 130. No specific limitation is made here.

[0065] The number of clips 142 can be selected as needed. In this embodiment, the first rib 130 is connected to two clips 142, which are distributed circumferentially along the first rib 130 to further improve the stability of the circuit board 200 assembled in the mounting space 131. Of course, the number of clearance openings 132 can correspond to the number of clips 142.

[0066] Furthermore, the two clips 142 are diagonally distributed relative to the housing 110; thus, the two clips 142 can be used to engage the two opposite corners of the circuit board 200 to improve the stability of the circuit board 200 assembled in the installation space 131.

[0067] In other embodiments, the number of latches 142 may be one, three, etc., and is not specifically limited here. For example, please refer to... Figure 5 Two of the multiple clips 142 are distributed on the same side of the mounting space 131 so that the two clips 142 can be simultaneously engaged on the same side of the circuit board 200, thereby improving the stability of the circuit board 200 assembled in the mounting space 131.

[0068] To prevent glue from leaking from the electrical control box 100; please refer to... Figure 1 and Figure 4 In this embodiment, the box body 110 further includes a second surrounding rib 150, which is connected to the first surrounding rib 130 and the support portion 120. The second surrounding rib 150 is located on the side of the first surrounding rib 130 away from the mounting space 131. The second surrounding rib 150 encloses a glue-holding cavity 151, and the clearance opening 132 connects the mounting space 131 and the glue-holding cavity 151. In this way, the glue overflowing from the clearance opening 132 can be contained in the glue-holding cavity 151, thus improving the problem of glue leaking out of the control box 100. The first surrounding rib 130 and the second surrounding rib 150 achieve a fully sealed structure, improving the problem of glue overflowing from the control box 100.

[0069] Furthermore, a portion of the support portion 120 together with the first surrounding rib 130 forms an installation space 131, and another portion of the support portion 120 extends from the side of the first surrounding rib 130 away from the installation space 131. That is, a portion of the support body 121 and the boss 122 together with the first surrounding rib 130 form an installation space 131, and another portion of the support body 121 extends from the side of the first surrounding rib 130 away from the installation space 131; the second surrounding rib 150 is connected to the support body 121 located outside the installation space 131.

[0070] It should be noted that the number of the second reinforcing ribs 150 and the corresponding glue-filling cavities 151 are adapted to the number of the clearance openings 132.

[0071] The connection methods of the buckle 142 to the first rib 130 and the connection methods of the second rib 150 to the first rib 130 and the support part 120 include, but are not limited to, integral molding and bonding.

[0072] Please refer to Figure 3 The electrical control box 100 in this embodiment also includes a first wiring section 170. The first wiring section 170 is connected to the side of the first reinforcing rib 130 opposite to the mounting space 131, and the first wiring section 170 is located outside the mounting space 131, used to limit the position of the wires connected to the circuit board 200 assembled in the mounting space 131. The connection method between the first wiring section 170 and the first reinforcing rib 130 includes, but is not limited to, integral molding and bonding. This arrangement can improve the problem of messy wiring.

[0073] Furthermore, the electrical control box 100 also includes a second wiring section 180, which is connected to the side of the first reinforcing rib 130 opposite to the mounting space 131. The second wiring section 180 is located outside the mounting space 131, and the first wiring section 170 and the second wiring section 180 are diagonally distributed relative to the box body 110. The second wiring section 180 is used to limit the position of the wires connected to the circuit board 200 assembled in the mounting space 131. The connection method between the second wiring section 180 and the first reinforcing rib 130 includes, but is not limited to, integral molding and bonding. This arrangement can improve the problem of messy wiring.

[0074] Furthermore, the first wiring section 170 is provided with a first wiring groove 171, and the second wiring section 180 is provided with a second wiring groove 181. Both the first wiring groove 171 and the second wiring groove 181 are used for inserting wires. The wiring grooves can improve the convenience of wiring.

[0075] Of course, in other embodiments, at least one of the first wiring portion 170 and the second wiring portion 180 may be provided with a wiring hole for threading a conductive wire.

[0076] In other embodiments, the control box 100 may not have the first wiring section 170 and the second wiring section 180, or may only have one of the first wiring section 170 and the second wiring section 180.

[0077] In other embodiments, the first wiring portion 170 may also be connected to the support portion 120; or, the second wiring portion 180 may also be connected to the support portion 120 and / or the second reinforcing bar 150.

[0078] In order to control the amount of glue used for potting and sealing, the height of the first reinforcing rib 130, the height of the supporting rib 141, and the spacing between the supporting part 120 and the circuit board 200 were designed and optimized.

[0079] Alternatively, please refer to Figure 6 and Figure 7 The ratio of the height H1 of the first retaining rib 130 to the height H2 of the supporting rib 141 is 2.000 to 8.000, for example: 2.000, 3.000, 4.000, 5.000, 6.000, 7.000, 8.000, etc., and is not specifically limited here. By adjusting the height ratio of the first retaining rib 130 and the second retaining rib 150, the amount of adhesive used can be significantly controlled, ensuring a good sealing effect while controlling costs.

[0080] For example, in some embodiments, the height H1 of the first reinforcing bar 130 is 10-16mm, such as 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, etc.; the height H2 of the supporting bar 141 is 2-5mm, such as 2mm, 3mm, 4mm, 5mm, etc., and is not specifically limited here.

[0081] By adjusting the height of the first reinforcing rib 130, the amount of adhesive used can be significantly controlled, ensuring a good potting and sealing effect while controlling costs. The height of the supporting rib 141 ensures a suitable distance between the circuit board 200 and the support portion 120. This guarantees sufficient adhesive volume between the circuit board 200 and the support portion 120, ensuring adequate adhesive volume within the potting cavity to guarantee a good sealing effect. Furthermore, it effectively controls adhesive usage and costs, avoiding waste of adhesive and other resources.

[0082] It should be noted that the distance between the end of the first rib 130 away from the support portion 120 and the end where the first rib 130 connects to the support portion 120 is the height H1 of the first rib 130; moreover, the distance between the end of the first rib 130 away from the support portion 120 and the end where the first rib 130 connects to the support portion 120 specifically refers to the distance between the end of the first rib 130 away from the support body 121 and the support plate.

[0083] Optionally, the distance between the support portion 120 and the circuit board 200 includes at least a first distance and a second distance, and the ratio of the first distance to the second distance is 0.556 to 0.943, for example: 0.556, 0.600, 0.735, 0.883, 0.943, etc.; for example, the first distance is 2.5-3.3mm (for example: 2.5mm, 2.7mm, 3.0mm, 3.2mm, 3.3mm, etc., which are not specifically limited here), and the second distance is 3.5-4.5mm (for example: 3.5mm, 3.7mm, 4.0mm, 4.2mm, 4.5mm, etc., which are not specifically limited here).

[0084] Optimizing the height between the support 120 and the circuit board 200, so that the gap between a part of the support 120 and the circuit board 200 is smaller than the gap between another part of the support 120 and the circuit board 200, can effectively control the amount of glue used, so as to save glue usage while ensuring good potting and sealing effect, thereby reducing costs.

[0085] Further, please refer to Figure 3 , Figure 8 and Figure 9 The support portion 120 includes a support body 121 and a boss 122 connected to the support body 121. A first retaining rib 130 is connected to both the support body 121 and the boss 122. The boss 122 is located within the mounting space 131. The gap between the boss 122 and the circuit board 200 is smaller than the gap between the support body 121 and the circuit board 200; that is, the gap between the boss 122 and the circuit board 200 is [value missing], and the gap between the support body 121 and the circuit board 200 is [value missing]. Of course, in other embodiments, the first retaining rib 130 may only be connected to the support body 121, which is not specifically limited here. By setting the boss 122, the distance between the support portion 120 and the circuit board 200 is locally reduced, which means the local height of the filling cavity is reduced. This allows for effective control of the amount of adhesive used, thereby saving adhesive usage while ensuring a good potting and sealing effect, achieving the goal of reducing costs.

[0086] Furthermore, please refer to Figure 9 The height D of the protrusion D of the boss 122 relative to the support body 121 is 0.5-1.5mm, for example: 0.5mm, 0.7mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, etc., and no specific limitation is made here. Optimizing the height difference between the boss 122 and the support body 121 can control the amount of glue used, ensure a good potting and sealing effect, and ensure the structural strength of the support part 120.

[0087] Optionally, the boss 122, the support body 121, and the first surrounding rib 130 can be integrally injection molded, with the boss 122 protruding relative to the support body 121 towards the interior of the mounting space 131. Of course, in other embodiments, the boss 122 can also be layered and connected to the side of the support body 121 facing the mounting space 131 by means of bonding or other methods, which is not specifically limited here.

[0088] It should be understood that in other embodiments, the spacing between the support portion 120 and the circuit board 200 may also include a third spacing different from the first spacing and the second spacing, etc., which are not specifically limited here.

[0089] Please refer to Figure 3 and Figure 7In this embodiment, the electrical control box 100 further includes a limiting rib 143, which is connected to the first surrounding rib 130 and the support portion 120, and is located on the side of the first surrounding rib 130 facing the mounting space 131; the limiting rib 143 abuts against the circuit board 200. By using the setting of the limiting rib 143 and making the limiting rib 143 abut against the circuit board 200, a point contact can be formed between the circuit board 200 and the first surrounding rib 130 through the limiting rib 143. At the same time, the contact between the support rib 141 and the circuit board 200 is also a point contact, thereby ensuring that a glue overflow gap 133 of appropriate width is formed between the circuit board 200 and the first surrounding rib 130, so as to improve the glue penetration rate during glue pouring, which is beneficial to improve the glue pouring and sealing efficiency, and ensure that the circuit board 200 can reliably achieve glue pouring and sealing on both sides facing the support portion 120 and away from the support portion 120, thereby improving the sealing effect.

[0090] Of course, in other embodiments, the limiting rib 143 may also be spaced apart from the circuit board 200.

[0091] Furthermore, the control box 100 includes multiple limiting ribs 143, all of which are connected to the first surrounding rib 130 and are spaced apart along the inner sidewall of the first surrounding rib 130. Some of the limiting ribs 143 are also connected to the support body 121, and others are connected to the boss 122. This allows for the formation of a ring of adhesive overflow gaps 133 around the outer periphery of the circuit board 200, further increasing the rate at which adhesive penetrates through the overflow gaps 133 during potting and sealing.

[0092] Of course, in other embodiments, the limiting rib 143 may also be connected to only one of the first surrounding rib 130 and the support portion 120.

[0093] Alternatively, please refer to Figure 7 The ratio of the width H3 of the glue overflow gap 133 to the height H4 of the circuit board 200 is 0.625 to 1.875, for example: 0.625, 0.755, 0.893, 0.991, 1.235, 1.555, 1.875, etc.; the ratio of the height H2 of the support rib 141 to the height H4 of the circuit board 200 is 1.250 to 3.125, for example: 1.250, 1.550, 1.800, 2.050, 2.350, 2.500, 2.850, 3.000, 3.125, etc.; for example, the width H3 of the glue overflow gap 133 is 1-3mm, for example: 1mm, 2mm, 3mm, etc.

[0094] In a preferred embodiment, the width H3 of the adhesive overflow gap 133 is 1-2 mm.

[0095] Optimizing the width of the glue overflow gap 133 increases the glue penetration rate during glue application, ensuring that both the side of the circuit board 200 facing the support 120 and the side of the circuit board 200 away from the support 120 are effectively covered by sealant, thus ensuring a good glue sealing effect on both sides of the circuit board 200. Controlling the height of the circuit board 200 to match the height of the first rib 130 and the support rib 141 ensures that both sides of the circuit board 200 facing the support 120 and the side of the circuit board 200 away from the support 120 are effectively covered by sealant, improving the sealing effect, while also controlling the amount of glue used to mitigate glue waste and increased costs.

[0096] Specifically, in this embodiment, the height H1 of the first reinforcing rib 130 is 12mm, the height H2 of the supporting rib 141 is 4mm, the width H3 of the glue overflow gap 133 is 2mm, and the height H4 of the circuit board 200 is 1.6mm.

[0097] Of course, in other embodiments, the height H4 of the circuit board 200 can also be 1.5mm, 1.7mm, etc., and is not specifically limited here.

[0098] Alternatively, please refer to Figure 3 The support portion 120 is provided with assembly reference numbers 160, which are distributed on the side of the first rib 130 opposite to the installation space 131. The assembly reference numbers 160 can be silkscreened onto the support portion 120. This arrangement allows for assembly processes such as wire insertion to be performed according to the instructions of the assembly reference numbers 160 during production, simplifying the assembly process and improving efficiency and accuracy.

[0099] Furthermore, the assembly reference 160 is disposed on the support body 121 located outside the mounting space 131. This arrangement can improve the problem of the assembly reference 160 being obscured by the circuit board 200, thereby ensuring the assembly indication function of the assembly reference 160.

[0100] In this embodiment, the outdoor unit of the air conditioner has an electrical control box assembly 010 mounted on the housing of the outdoor unit. The circuit board 200 of the electrical control box assembly 010 is mounted inside the electrical control box 100. The side of the circuit board 200 facing the support portion 120 of the electrical control box 100 and the side away from the support portion 120 are filled with sealant to ensure good sealing and waterproofing.

[0101] In summary, the electrical control box assembly 010 of this utility model can be used in the outdoor unit of an air conditioner. The electrical control box assembly 010 improves the potting efficiency and adhesive penetration rate of the electrical control box 100, and ensures a good potting and sealing effect on both sides of the circuit board 200 assembled in the electrical control box 100. This effectively prevents moisture and dust from entering the sealed circuit board 200, improving the problem of damage to the circuit board 200 due to moisture and dust, reducing the failure rate of the electrical control box assembly 010, and extending the service life of the air conditioner. Before potting or before the adhesive cures, it improves the stability of the circuit board 200 assembled in the electrical control box 100, improving the problem of poor potting and sealing effect caused by the circuit board 200 shifting within the electrical control box 100, and improving the problem of the circuit board 200 accidentally detaching from the electrical control box 100 and falling and being damaged. It also controls the amount of adhesive used, controlling costs while ensuring a good potting and sealing effect, and improving the problem of adhesive overflow.

[0102] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
