[0038] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] At present, in electrical equipment such as air conditioners, different wiring harnesses are usually installed on both sides of the electric control terminal block. When installing the terminal block, it is easy to install it upside down, causing safety hazards and return to the factory. It is necessary to perform anti-mistake positioning of the terminal block.

[0041] In the related art, a positioning post extends from the back of the terminal block, and a corresponding positioning hole is also provided at the mating position of the installed electrical box. When installing the terminal block, the positioning post and the positioning hole can only be matched if the terminal block is in the correct direction, thereby playing a fool-proof role. In the related art, the positioning post is provided on the back of the terminal block. During the installation process, it is not possible to see whether the positioning post and the matching positioning hole are on the same axis, resulting in the need to grope for installation, which reduces the installation efficiency.

[0042] In order to improve the installation efficiency of the terminal block while preventing the terminal block from being installed upside down, Figure 1-4 As shown, an embodiment of the present disclosure provides an electrical box 20 assembly, including a terminal block 10 and an electrical box 20 .

[0043] Combination Figure 1-4 As shown, the terminal block 10 is provided with a positioning through hole 11, which is offset from the center position of the terminal block 10; the electrical box 20 is provided with a mounting hole 21, which is correspondingly arranged with the positioning through hole 11; wherein, the terminal block 10 is installed in the electrical box 20; when the terminal block 10 is forwardly installed in the electrical box 20, the positioning through hole 11 is correspondingly communicated with the mounting hole 21; when the terminal block 10 is reversely installed in the electrical box 20, the positioning through hole 11 and the mounting hole 21 are misaligned with each other.

[0044] With the electrical box 20 assembly provided by the embodiment of the present disclosure, the positioning through hole 11 of the terminal row 10 is set away from the center position of the terminal row 10, so that when the terminal row 10 is installed in the electrical box 20 in different directions, the position of the positioning through hole 11 on the electrical box 20 is different. Only when the terminal row 10 is installed in the electrical box 20 in the forward direction, the positioning through hole 11 and the mounting hole 21 are correspondingly connected, and when the terminal row 10 is installed in the electrical box 20 in the forward direction, the positioning through hole 11 and the mounting hole 21 are correspondingly connected, and when the terminal row 10 is installed in the electrical box 20 in the reverse direction, the positioning through hole 11 and the mounting hole 21 are mutually misaligned, so that the terminal row 10 can be accurately positioned. When the terminal row 10 is to be reversed, since the positioning through hole 11 is not centered, after the direction is changed, the terminal row 10 will not be installed in place, thereby playing a fool-proof role and preventing the terminal row 10 from being installed upside down. During the installation process of the terminal row 10, the relative positions of the positioning through hole 11 and the mounting hole 21 can be directly viewed, which improves the installation efficiency. Therefore, the electrical box 20 assembly provided by the embodiment of the present disclosure can improve the installation efficiency while preventing the terminal block 10 from being installed upside down.

[0045] At the same time, compared with the related art, the terminal block 10 eliminates the positioning column, which can reduce the size of the terminal block 10. For a transport vehicle with the same capacity, more terminal blocks 10 can be placed, thereby reducing the transportation cost.

[0046] Optionally, the positioning through hole 11 is a through hole formed to extend through the entire thickness of the terminal block 10 .

[0047] The positioning through hole 11 is a through hole extending through the entire thickness of the terminal block 10. The axis of the positioning through hole 11 is consistent with the thickness direction of the terminal block body 12. The positioning through hole 11 cooperates with the mounting hole 21 provided in the electrical box 20, and can also perform installation and fixation between the terminal block 10 and the electrical box 20, so that the positioning through hole 11 and the mounting hole 21 simultaneously play the role of anti-mistake and installation and fixation.

[0048] Optionally, combined Figure 1-2 and Figure 4 As shown, the electrical box 20 is provided with a first limiting portion 22, which is located on at least one side of the terminal row 10 along the length direction, and limits the length direction of the terminal row 10 so that when the terminal row 10 is forwardly installed in the electrical box 20, the positioning through hole 11 corresponds to the mounting hole 21.

[0049] The length direction of the terminal row 10 is as follows Figure 1 During the installation of the terminal block 10, the first limiting portion 22 limits the terminal block 10 in the length direction of the terminal block 10, which can assist in aligning the positioning through hole 11 with the mounting hole 21 of the electrical box 20 more quickly and accurately. At the same time, the first limiting portion 22 can also prevent the terminal block 10 from being displaced during the installation process.

[0050] It can be understood that the first limiting portion 22 can be provided on either side of the electrical box 20 along the length direction of the terminal block 10, or can be provided on both sides of the electrical box 20 along the length direction of the terminal block 10. This application takes the example of the first limiting portion 22 being provided on one side of the electrical box 20 along the length direction of the terminal block 10, so that installation space for the terminal block 10 can be reserved on the other side of the electrical box 20 along the length direction of the terminal block 10, which facilitates quick installation of the electrical box 20.

[0051] Optionally, combined Figure 1 and Figure 4 As shown, the electrical box 20 includes a mounting plate 23, the terminal row 10 is suitable for being fixedly mounted on the mounting plate 23, the first limiting portion 22 includes a first limiting edge 221, the first limiting edge 221 is arranged on one side of the mounting plate 23 along the length direction of the terminal row 10, and extends along the width direction of the terminal row 10; wherein, when the positioning through hole 11 corresponds to and communicates with the mounting hole 21, the first limiting edge 221 can be against the terminal row 10.

[0052] The first limiting edge 221 can provide a clear limiting boundary along the length direction of the terminal block 10 on the mounting plate 23, accurately locate the position of the terminal block 10 relative to the mounting plate 23 along the length direction of the terminal block 10, simplify the installation process, and improve the installation efficiency. At the same time, the limiting structure of the first limiting edge 221 is simple and easy to process. The edge structure of the first limiting edge 221 can also form a strong support for the terminal block 10 to improve stability.

[0053] Optionally, combined Figure 1 and Figure 4 As shown, a bent edge 231 is provided on the edge of the mounting plate 23 along one side of the length direction of the terminal block 10 , and the first limiting edge 221 is formed by a portion of the bent edge 231 protruding toward the terminal block 10 .

[0054] The terminal block 10 is fixedly mounted on the mounting plate 23 , and a bending edge 231 is provided at the edge of the mounting plate 23 , which can enhance the mechanical strength of the mounting plate 23 , thereby enhancing the overall structural strength of the electrical box 20 .

[0055] The first limiting edge 221 is formed by part of the bent edge 231 protruding toward the terminal block 10, which can achieve a limiting effect while improving the structural strength of the electrical box 20. The first limiting edge 221 can be made by a stamping process, and a part of the bent edge 231 is stamped toward the terminal block 10 to form a convex edge structure. At this time, both sides of the first limiting edge 221 are connected to the remaining part of the bent edge 231, which can avoid affecting the strength of the bent edge 231.

[0056] The two side edges of the mounting plate 23 oppositely disposed along the length direction of the terminal block 10 can be provided with bent edges 231. It can be understood that the two side edges of the mounting plate 23 oppositely disposed along the width direction of the terminal block 10 can also be provided with reinforcing structures similar to the bent edges 231 to reinforce the structural strength.

[0057] It can be understood that the first limiting portion 22 can also be a limiting structure such as a first protrusion structure or a first groove.

[0058] Optionally, combined Figure 1-2 and Figure 4 As shown, the electrical box 20 is provided with a second limiting portion 24, which is located on at least one side of the terminal row 10 along the width direction, and limits the terminal row 10 in the width direction so that when the terminal row 10 is forwardly installed in the electrical box 20, the positioning through hole 11 corresponds to the mounting hole 21.

[0059] The width direction of the terminal row 10 is as follows Figure 2 During the installation of the terminal block 10, the second limiting portion 24 limits the terminal block 10 in the width direction of the terminal block 10, which can assist in aligning the positioning through hole 11 with the mounting hole 21 of the electrical box 20 more quickly and accurately. At the same time, the second limiting portion 24 can also prevent the terminal block 10 from shifting during the installation process.

[0060] It can be understood that the second limiting portion 24 can be provided on any side of the electrical box 20 along the width direction of the terminal block 10, or can be provided on both sides of the electrical box 20 along the width direction of the terminal block 10. This application takes the second limiting portion 24 provided on one side of the electrical box 20 along the width direction of the terminal block 10 as an example, so that installation space for the terminal block 10 can be reserved on the other side of the electrical box 20 along the width direction of the terminal block 10, which facilitates quick installation of the electrical box 20.

[0061] Optionally, the electrical box 20 is provided with a first limiting portion 22 and a second limiting portion 24, the first limiting portion 22 is located on one side of the terminal row 10 along the length direction, and limits the terminal row 10 in the length direction; the second limiting portion 24 is located on one side of the terminal row 10 along the width direction, and limits the terminal row 10 in the width direction, so that when the terminal row 10 is installed in the electrical box 20 in the forward direction, the positioning through hole 11 corresponds to the mounting hole 21 and is connected.

[0062] By providing a first limiting portion 22 on one side of the length direction of the terminal row 10 on the electrical box 20 and providing a second limiting portion 24 on one side of the width direction of the terminal row 10 on the electrical box 20, the terminal row 10 can be limited in both the length direction and the width direction of the terminal row 10, and positioning can be performed more accurately and quickly. At the same time, installation space is reserved on the other side of the electrical box 20 along the length direction of the terminal row 10 and the other side of the electrical box 20 along the width direction of the terminal row 10, which can improve the installation efficiency of the terminal row 10.

[0063] Optionally, combined Figure 1-2 and Figure 4 As shown, the electrical box 20 includes a mounting plate 23, the terminal row 10 is suitable for being fixedly mounted on the mounting plate 23, the second limiting portion 24 includes a second limiting edge 241, the second limiting edge 241 is arranged on one side of the mounting plate 23 along the width direction of the terminal row 10, and extends along the length direction of the terminal row 10; wherein, when the positioning through hole 11 corresponds to and communicates with the mounting hole 21, the second limiting edge 241 can be against the terminal row 10.

[0064] The second limiting edge 241 can provide a clear limiting boundary along the width direction of the terminal row 10 on the mounting plate 23, accurately locate the position of the terminal row 10 relative to the mounting plate 23 along the width direction of the terminal row 10, and improve the installation efficiency. At the same time, the limiting structure of the second limiting edge 241 is simple and easy to process. The side body structure of the second limiting edge 241 can also form a strong support for the terminal row 10 to improve stability.

[0065] It can be understood that the second limiting portion 24 can also be a limiting structure such as a second protrusion structure or a second groove.

[0066] Optionally, combined Figure 4 As shown, the mounting plate 23 is provided with an opening 232 , and the second limiting edge 241 is formed by bending the mounting plate 23 at the opening 232 toward the terminal block 10 .

[0067] The second limiting edge 241 is formed by bending the plate body of the mounting plate 23 at the opening 232 toward the terminal row 10, which is simple in process and can save material costs. At the same time, the opening 232 can increase the ventilation area of ​​the contact surface between the terminal row 10 and the mounting plate 23, which is helpful for heat dissipation.

[0068] In the present application, the mounting plate 23 is provided with a first limiting edge 221 along the length direction of the terminal row 10, and the mounting plate 23 is provided with a second limiting edge 241 along the width direction of the terminal row 10. By respectively providing limiting edge structures on the mounting plate 23 of the electrical box 20, limiting is achieved from two directions. During installation, the positions of the first limiting edge 221 and the second limiting edge 241 can be directly viewed, saving time in finding the limiting position, and the fixing hole can be quickly matched with the mounting hole 21 during installation. Since the positioning through hole 11 of the terminal row 10 is not centered, when the terminal row is arranged in the wrong direction and the terminal row is arranged on the first limiting edge 221 and the second limiting edge 241, the positioning through hole 11 and the mounting hole 21 are misaligned with each other and cannot correspond to each other, thereby playing a fool-proof role.

[0069] It is understandable that the first limiting edge 221 can also be formed by bending the plate body of the mounting plate 23 located at the opening 232 upward, and the second limiting edge 241 can be formed by the partial bending edge 231 set on the edge of the mounting plate 23 on one side of the width direction of the terminal row 10 protruding toward the terminal row 10.

[0070] Optionally, combined Figure 2-3 As shown, the terminal block 10 includes a terminal block body 12 and a plurality of terminals, and a positioning through hole 11 is provided in the terminal block body 12; the plurality of terminals are respectively provided at both ends of the terminal block body 12 along the width direction, and the plurality of terminals are arranged along the length direction of the terminal block body 12 for connecting the wiring harness 30; wherein, when the electrical box 20 is provided with a second limiting portion 24, the height of the lower edge of the terminal is higher than the height of the second limiting portion 24.

[0071] The positioning through hole 11 is provided on the terminal block body 12 , and can realize fool-proofing and installation functions without affecting the normal use of the terminal block 10 .

[0072] A plurality of terminals are respectively arranged at both ends of the terminal block body 12 in the width direction, and the second limit portion 24 is arranged on the electrical box 20, and the second limit portion 24 is located at least on one side of the terminal block 10 in the width direction. The height of the lower edge of the terminal is higher than the height of the second limit portion 24, which can prevent interference between the terminal and the second limit portion 24, so that the routing height of the wiring harness 30 connected to the terminal is higher than the height of the second limit portion 24, which can avoid affecting the connection effect between the terminal and the wiring harness 30.

[0073] Optionally, the mounting hole 21 is provided with a thread, suitable for cooperating with a bolt, so that the bolt fixes the terminal block 10 and the electrical box 20 .

[0074] The mounting hole 21 is provided with threads by tapping, and the terminal block 10 and the electrical box 20 are fixed together by bolts, and the bolt thread fixing method is simple and has good stability. At the same time, the positioning through hole 11 and the mounting hole 21 can not only play a fool-proof role, but also have the function of installation and fixing.
