Detailed Implementation

[0017] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0018] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0019] As described above, the support assembly is used to fix, support, and insulate the busbars. The support assembly is integrally molded. When using a support assembly intended for a large number of busbars for a small number of busbars, the excess portion of the support assembly can be retained or cut off. However, on the one hand, retaining the excess portion will occupy the limited space within the electrical cabinet, thus interfering with the installation of other electrical components. On the other hand, the support assembly is not easy to cut, increasing the difficulty of operation.

[0020] Based on this, embodiments of the present disclosure provide a busbar support assembly and an electrical cabinet to at least partially solve the above-mentioned problems. In the following, [the following will be combined with...] Figures 1 to 4 The principles of this disclosure are described.

[0021] Figure 1A partial structural schematic diagram of an electrical cabinet according to some embodiments of the present disclosure is shown. Figure 2 An exploded view of a busbar support assembly 100 according to some embodiments of the present disclosure is shown. Figure 1 and Figure 2 As shown, the busbar support assemblies 100 described herein are arranged in pairs, with the pairs of busbar support assemblies 100 arranged along a second direction Y. Each busbar support assembly 100 includes a base member 1 and a connector 2. The connector 2 is detachably connected to the base member 1.

[0022] refer to Figure 1 and Figure 2 In some embodiments, the base member 1 extends along a first direction X and has a first end 101 and a second end 102. The first end 101 and the second end 102 are disposed opposite to each other in the first direction X. The base member 1 is integrally formed and includes at least two limiting portions 3. The at least two limiting portions 3 are spaced apart from each other in the first direction X to limit corresponding busbars 200, so the base member 1 can be used to limit at least two busbars 200. The first direction X may be perpendicular to the second direction Y.

[0023] Continue to refer to Figure 1 and Figure 2 The connector 2 is detachably connected to the first end 101. Because the connector 2 and the base 1 are detachably connected, disassembly and installation are simplified. The connector 2 includes at least one limiting part 3 to limit a corresponding busbar 200, thus the base 1 can be used to limit at least one busbar 200.

[0024] According to embodiments of this disclosure, a connector 2 that limits at least one busbar 200 is detachably connected to a base member 1 that limits at least two busbars 200. When the busbar support assembly 100 is used for a small number of busbars 200, the connector 2 can be removed from the base member 1. In this way, on the one hand, the difficulty of operation is reduced, and the operating cost is reduced. On the other hand, the size of the busbar support assembly 100 with the connector 2 removed is reduced, reducing the space occupied in the electrical cabinet, thereby avoiding interference with the installation of other electrical components.

[0025] The limiting part 3 according to the embodiments of this disclosure can be of various types known or available in the future, and the embodiments of this disclosure are not limited thereto, as long as it can be used to limit the busbar 200. For example, continue to refer to Figure 2 In some embodiments, each limiting part 3 may include a limiting groove. Each limiting groove may accommodate a portion of the corresponding busbar 200 to engage the corresponding busbar 200.

[0026] Continue to refer to Figure 1 and Figure 2In some embodiments, the base component 1 may include three limiting parts 3, and the connector 2 may include a single limiting part 3. In this way, the busbar support assembly 100 according to the embodiments of the present disclosure can be used for three and four busbars 200 at the same time, and when used for three busbars 200, the connector 2 can be removed from the base component 1, which is simple and reliable.

[0027] It should be noted that the numbers, values, and quantities mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable numbers, values, and quantities are possible. For example, depending on the specific application scenario and requirements, in some embodiments, the base component 1 may further include two limiting parts 3, and the connector 2 may include a single limiting part 3. In this way, the busbar support assembly 100 according to the embodiments of this disclosure can be used simultaneously for two and three busbars 200, and when used for two busbars 200, it is only necessary to disassemble the connector 2 from the base component 1, making the operation simple and reliable. In some embodiments, the base component 1 may include two limiting parts 3, and the connector 2 includes two limiting parts 3. In this way, the busbar support assembly 100 according to the embodiments of this disclosure can be used simultaneously for two and four busbars 200, and when used for two busbars 200, it is only necessary to disassemble the connector 2 from the base component 1, making the operation simple and reliable.

[0028] The detachable connection method according to the embodiments of this disclosure can be any type of detachable method currently known or available in the future, and the embodiments of this disclosure do not limit this. For example, in some embodiments, the base component 1 and the connector 2 are interlocked to form a whole. For example, in other embodiments, the base component 1 and the connector 2 can also be connected to each other by other components such as bolts or screws. In the following, the example structure and example principle of the busbar support assembly 100 of this disclosure will be described mainly with the base component 1 and the connector 2 interlocking. Other detachable methods are the same or similar, and this disclosure will not elaborate on them.

[0029] Figure 3 A schematic diagram of the structure of the base component 1 according to some embodiments of the present disclosure is shown. Figure 4 A schematic diagram of the structure of the connector 2 according to some embodiments of the present disclosure is shown. For example... Figures 2 to 4 As shown, in some embodiments, the base component 1 may include a first snap-fit ​​portion 111. The connector 2 may include a second snap-fit ​​portion 22. The first snap-fit ​​portion 111 can snap onto the second snap-fit ​​portion 22. Compared with traditional bolt fixing or binding fixing methods, the snap-fit ​​method has the advantages of simple operation, easy disassembly, and stable and reliable connection.

[0030] The first snap-fit ​​portion 111 may include one of a snap-fit ​​strip and a snap-fit ​​groove. The second snap-fit ​​portion 22 may include the other of a snap-fit ​​strip and a snap-fit ​​groove. The snap-fit ​​strip can snap into the snap-fit ​​groove to achieve snap-fit ​​fixation between the base member 1 and the connector 2. For example, refer to... Figures 2 to 4 In some embodiments, the first snap-fit ​​portion 111 may include a snap-fit ​​groove, and the second snap-fit ​​portion 22 may include a snap-fit ​​strip. In other embodiments, the first snap-fit ​​portion 111 may further include a snap-fit ​​strip, and the second snap-fit ​​portion 22 may further include a snap-fit ​​groove. In this way, the snap-fit ​​strip can be inserted into the snap-fit ​​groove along the first direction X, and the snap-fit ​​strip and the snap-fit ​​groove are snapped together.

[0031] In the following description, the exemplary structure and principle of the busbar support assembly 100 of this disclosure will be mainly described with reference to the first snap-fit ​​portion 111 including a snap-fit ​​groove and the second snap-fit ​​portion 22 including a snap-fit ​​strip. Other cases are the same or similar, and will not be described in detail here.

[0032] refer to Figure 2 and Figure 3 In some embodiments, the base component 1 further includes a first mounting portion 11 and a first main body portion 12. The first mounting portion 11 is located at a first end 101 in a first direction X and is connected to the first main body portion 12. At least two limiting portions 3 may be provided on the first main body portion 12 to engage the busbar 200 with the first main body portion 12. The first mounting portion 11 has a first mounting surface 112 extending along the first direction X and perpendicular to the second direction Y. A first engaging portion 111 may be provided on the first mounting surface 112.

[0033] Continue to refer to Figure 2 and Figure 4 Correspondingly, the connector 2 may further include a second mounting portion 21 and a second main body portion 23. The second mounting portion 21 and the second main body portion 23 are connected, and the second main body portion 23 is located on the side of the second mounting portion 21 facing away from the base member 1. At least one limiting portion 3 may be provided on the second main body portion 23 to allow the busbar 200 to engage with the second main body portion 23. The second mounting portion 21 has a second mounting surface 211 extending along a first direction X, and the second mounting surface 211 is perpendicular to the second direction Y. The second mounting surface 211 may abut against a first mounting surface 112, and a second engaging portion 22 may be provided on the second mounting surface 211. It is understood that when the first engaging portion 111 and the second engaging portion 22 are engaged, the second mounting surface 211 may abut against the first mounting surface 112. In this way, the gap between the second mounting surface 211 and the first mounting surface 112 is reduced, which on the one hand helps to improve the aesthetics of the connection between the base member 1 and the connector 2, and on the other hand, helps to improve the firmness of the connection between the base member 1 and the connector 2.

[0034] refer to Figures 2 to 4 Furthermore, the thickness of the first mounting portion 11 along the second direction Y is less than the thickness of the first main body portion 12 along the second direction Y, and the thickness of the second mounting portion 21 along the second direction Y is less than the thickness of the second main body portion 23 along the second direction Y. In this way, it is beneficial to reduce the total thickness of the base component 1 and the connector 2 after assembly.

[0035] Continue to refer to Figure 3 In some embodiments, the first mounting portion 11 may also have a third mounting surface 113. The third mounting surface 113 may be disposed away from the second end 102 and perpendicular to the first direction X. The first engaging portion 111 extends a distance toward the second end 102 from the third mounting surface 113 in the first direction X. Therefore, when the second engaging portion 22 is pushed along the first direction X, the second engaging portion 22 can be pushed from the third mounting surface 113 into the first engaging portion 111, thereby engaging the base member 1 and the connector 2 with each other, and the operation process is simple.

[0036] Continue to refer to Figure 3 and Figure 4 In some embodiments, the dimension of the portion of the first latching portion 111 adjacent to the first mounting surface 112 is smaller than the dimension of the portion distant from the first mounting surface 112. Correspondingly, the dimension of the portion of the second latching portion 22 adjacent to the second mounting surface 211 is smaller than the dimension of the portion distant from the second mounting surface 211. That is, the base member 1 and the connector 2 are connected by a mortise and tenon structure. Therefore, the busbar support assembly 100 effectively distributes the load and stress throughout the entire structure through the interlocking relationship, making the structure of the busbar support assembly 100 more stable and able to withstand greater external forces.

[0037] Continue to refer to Figure 3 and Figure 4 Furthermore, the paired inner wall surfaces of the first latching portion 111 are inclined relative to the first mounting surface 112 and parallel to the first direction X. The distance between the paired inner wall surfaces of the first latching portion 111 gradually increases in the direction away from the first mounting surface 112. Correspondingly, the paired side surfaces of the second latching portion 22 are inclined relative to the second mounting surface 211 and parallel to the first direction X. The distance between the paired side surfaces of the second latching portion 22 gradually increases in the direction away from the second mounting surface 211. Each of the paired inner wall surfaces of the first latching portion 111 abuts against the corresponding side surface of the second latching portion 22. In this way, the structure of the busbar support assembly 100 is more stable and can withstand greater external forces. In addition, the paired inner wall surfaces also serve as guides to facilitate pushing the second latching portion 22 into the first latching portion 111 along the first direction X.

[0038] Continue to refer to Figures 1 to 4In some embodiments, the first mounting portion 11 may further have a first hole 13 extending along the second direction Y, and the first hole 13 may communicate with the first snap-fit ​​portion 111. The second mounting portion 21 may further have a second hole 24 extending along the second direction Y and extending to the second snap-fit ​​portion 22. The first hole 13 and the second hole 24 may be aligned along the second direction Y to accommodate the mounting member 300. Therefore, in addition to the mortise and tenon structure connection between the base member 1 and the connector 2, the mounting member 300 further reinforces the connection, thereby improving the connection stability between the base member 1 and the connector 2 and effectively supporting the busbar 200.

[0039] Continue to refer to Figures 1 to 4 Embodiments of this disclosure also provide an electrical cabinet including paired busbar support assemblies 100, a plurality of busbars 200, and a plurality of mounting members 300. Each busbar support assembly 100 includes any of the busbar support assemblies 100 described above. The plurality of busbars 200 are disposed between the paired busbar support assemblies 100, for example, each being confined within a corresponding limiting portion 3 of the paired busbar support assembly 100.

[0040] Continue to refer to Figures 1 to 4 The paired busbar support assemblies 100 are arranged along the second direction Y, and the limiting portions 3 of the paired busbar support assemblies 100 are arranged adjacent to each other to limit the busbar 200.

[0041] Continue to refer to Figures 1 to 4 The first main body 12 may also have at least two through holes 4, which are arranged along a first direction X. The second main body 23 may also have at least one through hole 4. Each through hole 4 may extend along a second direction Y and is used to receive a corresponding mounting member 300. Each mounting member 300 is capable of connecting a pair of busbar support assemblies 100, and each busbar 200 is located between adjacent mounting members 300. In this way, the pair of busbar support assemblies 100 can be connected together by a plurality of mounting members 300, improving connection reliability, and the plurality of busbars 200 can be securely positioned between the pair of busbar support assemblies 100.

[0042] The mounting component 300 according to embodiments of this disclosure can be of various types currently known or future available, and embodiments of this disclosure do not limit this. For example, continue to refer to Figure 1 In some embodiments, the mounting member 300 may include mounting bolts or screws. The mounting member 300 may pass through one of the busbar support assemblies 100 and be confined within the other busbar support assembly 100 for securing the pair of busbar support assemblies 100.

[0043] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
