Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0026] The electrical control box assembly provided in the embodiments of this application, such as Figures 2 to 6As shown, it includes: an electrical control box 100, which has a first plug-in portion and a second plug-in portion; and a terminal board 200, which has a first plug-in mating portion and a second plug-in mating portion. The first plug-in portion and the first plug-in mating portion are plugged into each other along a first direction, and the second plug-in portion and the second plug-in mating portion are plugged into each other along a second direction. The first direction and the second direction intersect.

[0027] The electrical control box assembly has a first direction and a second direction intersecting. This way, the second plug-in part and the second plug-in mating part will prevent the first plug-in part and the first plug-in mating part from disengaging, and the first plug-in part and the first plug-in mating part will also prevent the second plug-in part and the second plug-in mating part from disengaging. In this way, the terminal board 200 and the electrical control box 100 are pre-fixed together. At this time, the operator does not need to hold the terminal board 200, and the terminal board 200 will not disengage from the electrical control box 100. Therefore, the operator has less difficulty in fixing the electrical control box 100 and the terminal board 200 afterward.

[0028] In some examples, such as Figure 1 , Figure 4 and Figure 6 As shown, the electrical control box 100 is provided with a connecting part, and the terminal board 200 is provided with a connecting mating part. The connecting part and the connecting mating part are fixedly connected to each other, so that the terminal board 200 and the electrical control box 100 are fixedly connected together. With this solution, the operator does not need to hold the terminal board 200 when fixing the terminal board 200 and the electrical control box 100 (i.e., fixing the connecting part and the connecting mating part), and the operation is easy.

[0029] In some embodiments, such as Figures 2 to 6 As shown, the first plug-in part is a bent (such as L-shaped) plug rib 113. The plug rib 113 and the electrical control box 100 together form a first groove. The first plug-in mating part is a first plug hole 210. The plug rib 113 is inserted into the first plug hole 210. This scheme has a simple structure and is easy to manufacture.

[0030] In some embodiments, such as Figures 2 to 6As shown, the second insertion part is a second insertion block 114, which protrudes from the side of the insertion rib 113 facing the control box 100. The side of the insertion rib 113 facing the control box 100 forms a second groove 300 in the area between the control box 100 and the second insertion block 114. The second insertion mating part is a second insertion hole 220. A common wall 115 between the first insertion hole 210 and the second insertion hole 220 extends from the opening of the first groove through the first groove and is placed within the second groove 300. Simultaneously, the second... Insertion block 114 is inserted into the second socket 220. Specifically, insertion rod 113 and insertion block 114 are first inserted together into the first socket 210 along the first direction. After insertion rod 113 and insertion block 114 are properly inserted into the first socket 210, insertion rod 113 and insertion block 114 are moved along the second direction, causing the second insertion block 114 to insert into the second socket 220. Correspondingly, the common wall 115 between the first and second sockets 210 will be engaged within the second groove 300. In this design, the second insertion block 114 prevents the common wall 115 from moving towards the opening of the first groove in the first direction, thus pre-fixing the terminal board 200 and the electrical control box 100 together and preventing them from separating. During the subsequent process of fixing the connection part and the connection mating part, the operator does not need to hold the terminal plate 200, and the terminal plate 200 will not be detached from the electrical control box 100. Therefore, the operator's subsequent operation of fixing the electrical control box 100 and the terminal plate 200 is relatively easy.

[0031] like Figure 5 As shown, to ensure that the insert 113 can be smoothly inserted into the first insertion hole 210: T2 = 2*T + K, T1 = T2 + T + K; where T1 is the distance between the bottom of the second groove 300 and the electrical control box 100, T2 is the distance between the second insert block 114 and the electrical control box 100, T is the thickness of the horizontal plate section, and K is 0.1mm to 2mm.

[0032] It could be that the insert 113, the second insert block 114, the first insert hole 210, and the second insert hole 220 comprise a set; or it could be, as... Figure 2 , Figure 4 and Figure 6 As shown, the insert 113, the second insert block 114, the first insert hole 210 and the second insert hole 220 include multiple sets, which may be two, three or four sets, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be repeated here, and all should fall within the protection scope of this application.

[0033] In some embodiments, such as Figure 2 and Figure 6As shown, the terminal block 200 includes a horizontal plate segment and a vertical plate segment. The horizontal plate segment is located between the vertical plate segment and the electrical control box 100 and is connected to the vertical plate segment. The first socket 210 is located at the connection between the horizontal plate segment and the vertical plate segment, and the second socket 220 is located on the horizontal plate segment. This design not only facilitates the quick insertion of the insertion rod 113 into the first socket 210, but also facilitates the quick insertion of the second insertion block 114 into the second socket 220.

[0034] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the electrical control box 100 includes a base 110, a control board, and a cover 120. The base 110 includes a mounting part 111 and a mating part 112. The control board is located on the mounting part 111. The cover 120 is mounted on the mounting part 111 and covers the control board. The mating part 112 is located outside the area enclosed by the cover 120 and the mounting part 111. The insert rib 113 is located on the mating part 112. The cover 120 is located on the upper side of the base 110, the insert rib 113 and the terminal plate 200 are located on the lower side of the base 110, and the cover 120 is provided with an extension edge 121. The extension edge 121 is placed in the mating part 112 and is provided with a countersunk hole. The mating part 112 is provided with a through hole, and the countersunk hole is placed in the through hole. The horizontal plate section of the terminal plate 200 is provided with a screw hole. The connecting part includes a countersunk hole and a through hole. The connecting mating part includes a screw hole. Based on the insertion of the insert rib into the first insert hole and the insertion of the second insert into the second insert hole, the countersunk hole and the through hole are aligned with the screw hole. At this time, the screw is screwed into the screw hole through the countersunk hole (see position a in the figure) to realize the fixed connection between the electrical control box 100 and the terminal plate 200.

[0035] It can be a group consisting of countersunk holes, through holes, and threaded holes; or it can be, for example... Figure 1 , Figure 4 and Figure 6 As shown, the countersunk holes, through holes, and screw holes include multiple sets, which may be two, three, or four sets, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be repeated here, and all should fall within the protection scope of this application.

[0036] In some embodiments, such as Figures 3 to 6 As shown, the terminal block 200 is also provided with a third plug-in part, and the electrical control box 100 is also provided with a third plug-in mating part. Since the screw passes through the countersunk hole and is screwed into the screw hole, the third plug-in part and the third plug-in mating part are plugged and connected in the second direction. This can effectively prevent the terminal block 200 from rotating relative to the base 110 under the drive of the rotating screw.

[0037] It can be, such as Figures 3 to 6As shown, the third insertion part is the first insertion block 230, and the third insertion mating part is the slot 116; or it can be that the third insertion part is the slot 116, and the third insertion mating part is the first insertion block 230, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0038] In some embodiments, such as Figure 1 As shown, the base 110 is made of plastic, the cover 120 is made of metal, and the mating part 112 is provided with a wiring structure. The wiring structure is spaced apart from the cover 120, and the connecting line 400 is located inside the wiring structure. This can prevent the sharp edges on the cover 120 from scratching the connecting line 400.

[0039] Among them, such as Figure 1 As shown, the mating part 112 is provided with a vertical rib 117 and an anti-detachment hook 118. The anti-detachment hook 118 is located on one side of the vertical rib 117 and together with the vertical rib 117 forms a cable tray 119. The cable tray structure includes the cable tray 119, and the connecting line 400 is located in the cable tray 119. The anti-detachment hook 118 prevents the connecting line 400 from coming out of the cable tray 119. This solution has a simple structure and is easy to manufacture.

[0043] This air conditioner possesses all the advantages of the outdoor unit provided in any of the above embodiments, which will not be repeated here.

[0044] In summary, the technical solution provided by the embodiments of this application has the first direction and the second direction intersecting. In this way, the second plug-in part and the second plug-in mating part will prevent the first plug-in part and the first plug-in mating part from disengaging, and the first plug-in part and the first plug-in mating part will also prevent the second plug-in part and the second plug-in mating part from disengaging from each other. In this way, the terminal board and the electrical control box are pre-fixed together. At this time, the operator does not need to hold the terminal board, and the terminal board will not disengage from the electrical control box. Therefore, the operator has less difficulty in fixing the electrical control box and the terminal board later.
