While preferred 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.

[0032] Conventional electrical switches, such as circuit breakers, can be back-mounted on a carrier. However, as user needs change, side-mounting installation is becoming more popular when installing electrical switches in electrical cabinets widely used in new energy industries such as energy storage. However, for conventional electrical switches, side-mounting requires additional mounting components such as mounting plates, increasing installation complexity and cost. Therefore, embodiments of this disclosure provide an electrical switch to at least partially address the aforementioned problems. In the following sections, [further details will be provided]. Figures 1 to 7 The principles of this disclosure are described.

[0033] Figure 1 A schematic diagram of the installation of an electrical switch 100 according to some embodiments of the present disclosure is shown. Figure 2 A schematic diagram of the installation of an electrical switch 100 according to other embodiments of the present disclosure is shown. Figure 3 It shows Figure 2 A partial structural schematic diagram of the electrical switch 100 shown. Figures 1 to 3 As shown, the electrical components described herein generally include a housing 1, a mounting component 2, a stationary contact 3, a connector 4, a gasket 5, a terminal nut 6, and a mounting cap 7, wherein the connector 4, gasket 5, and terminal nut 6 are all located within... Figure 6 It is shown in the middle.

[0034] Figure 4 It shows Figure 2 The diagram shows the structure of the mounting component 2 of the electrical switch 100. Figure 5 It shows Figure 2 The diagram shows the fit between the housing 1 and the mounting component 2. Figures 2 to 5As shown, in some embodiments, the housing 1 includes a mounting side 11, a plurality of mounting holes 12, and a plurality of snap-fit ​​members 13. The mounting side 11 can abut against the inner wall of the electrical cabinet 200 to allow the electrical switch 100 to be installed inside the electrical cabinet 200. Each of the plurality of snap-fit ​​members 13 is disposed within a corresponding mounting hole 12. Correspondingly, a plurality of mounting members 2 are adapted to be fixed to the electrical cabinet 200, and each of the plurality of mounting members 2 includes a body 21 and a snap-fit ​​groove 22 disposed on the body 21. The body 21 can be inserted into the corresponding mounting hole 12, and the snap-fit ​​groove 22 can engage with the corresponding snap-fit ​​member 13 to achieve a snap-fit ​​engagement between the plurality of mounting members 2 and the housing 1. In this manner, during installation, the bodies 21 of the plurality of mounting members 2 can be inserted into the corresponding mounting holes 12, and the plurality of snap-fit ​​members 13 are snapped into the corresponding snap-fit ​​groove 22 of the mounting member 2.

[0035] Continue to refer to Figure 3 Furthermore, multiple mounting holes 12 are adapted to be located adjacent to the mounting side 11, thereby facilitating the side-mounting of the electrical switch 100 within the electrical cabinet 200.

[0036] According to the embodiments of this disclosure, since multiple mounting holes 12 are located adjacent to the mounting side 11, when side-mounted installation is required, the bodies 21 of multiple mounting parts 2 can be inserted into the corresponding mounting holes 12. The housing 1 and the multiple mounting parts 2 are fixed relative to each other through the cooperation of the snap-fit ​​part 13 and the snap-fit ​​groove 22. Then, the operator can install the product in the electrical cabinet 200 through the multiple mounting parts 2. The structure is simple, the installation is reliable, and it is beneficial to reduce costs.

[0037] In addition, return to reference Figure 1 According to embodiments of this disclosure, the electrical switch 100 can also be mounted on a carrier via a plurality of fastening bolts 101. The structural design can accommodate both back-mounted and side-mounted installation methods to meet customer needs for different installation locations, without affecting the product's overall dimensions.

[0038] like Figure 2 and Figure 5 As shown, in order to enable the mounting member 2 to fix the housing 1 inside the electrical cabinet 200, in some embodiments, the bodies 21 of the plurality of mounting members 2 may each include an insertion portion 211, an inclined portion 212, and a mounting portion 213. The inclined portion 212 is inclinedly disposed between the insertion portion 211 and the mounting portion 213. The insertion portion 211 is adapted to be inserted into a corresponding mounting hole 12 and engages with a snap-fit ​​member 13. The mounting portion 213 is adapted to be fixed to the electrical cabinet 200, and the mounting portion 213 can contact the inner wall surface of the electrical cabinet 200. It should be understood that in other embodiments, the bodies 21 of the mounting member 2 may also adopt other suitable structures to fix the housing 1 inside the electrical cabinet 200.

[0039] Compared to mounting component 2, which is installed inside housing 1 with screws, ensuring a secure installation requires screws to be driven sufficiently deep into housing 1, thus reducing space utilization. According to embodiments of this disclosure, since mounting component 2 is snap-fitted into housing 1, compared to screw installation, space utilization is improved and the range of applications is expanded. Furthermore, installation reliability is enhanced, avoiding issues such as easily stripped screws and weak installation strength.

[0040] refer to Figure 4 and Figure 5 Furthermore, the insertion portion 211 and the mounting portion 213 can each extend along the first direction X. Correspondingly, the mounting hole 12 can extend along the first direction X, thereby facilitating the insertion of the mounting member 2 into the corresponding mounting hole 12 along the first direction X, and facilitating the assembly of the electrical switch 100 into the electrical cabinet 200. A snap-fit ​​groove 22 can be provided on the insertion portion 211. (Continue referring to...) Figure 4 and Figure 5 According to an embodiment of the present disclosure, the snap-fit ​​groove 22 can penetrate the insertion portion 211. Obviously, in some other embodiments, the snap-fit ​​groove 22 may not penetrate the insertion portion 211, and the snap-fit ​​groove 22 may be provided on one side of the insertion portion 211 adjacent to the mounting side 11.

[0041] The mounting component 2 according to embodiments of this disclosure can be assembled within the electrical cabinet 200 in any suitable manner, and embodiments of this disclosure do not limit this. For example, continuing to refer to... Figure 2 , Figure 4 as well as Figure 5 In some embodiments, the mounting portion 213 is provided with fastening holes 23. Fastening bolts 101 can pass through the corresponding fastening holes 23 to assemble the electrical switch 100 into the electrical cabinet 200.

[0042] Continue to refer to Figure 4 and Figure 5 In some embodiments, each of the plurality of mounting holes 12 may include a first portion 121 and a second portion 122. The first portion 121 may extend along the first portion 121 so that the insertion portions 211 of the plurality of mounting members 2 are respectively inserted into the corresponding first portion 121. The second portion 122 may communicate with the first portion 121 and may extend to the mounting side 11. A snap-fit ​​member 13 may be located within the first portion 121 and adjacent to the second portion 122 to facilitate the forming of the snap-fit ​​member 13 within the mounting hole 12.

[0043] Continue to refer to Figure 4 and Figure 5In some embodiments, the first portions 121 of the plurality of mounting holes 12 may each include a first side surface 1211. The first side surface 1211 may be disposed opposite to the mounting side surface 11. The distance H between the opposite sides of the insertion portion 211 and the mounting portion 213 may be greater than the distance D between the first side surface 1211 and the mounting side surface 11. In this way, when the electrical switch 100 is mounted in a side-lying position, the body 21 of the mounting member 2 can be deformed by the force exerted by the gravity of the electrical switch 100. (Continue referring to...) Figure 5 The insertion part 211 is tilted under force, and one end of the insertion part 211 adjacent to the mounting part 213 is tilted upward away from the mounting side 11 to increase the contact area between the snap-fit ​​part 13 and the snap-fit ​​groove 22, thereby achieving self-locking and making it difficult for the mounting part 2 to fall out of the mounting hole 12.

[0044] Obviously, to ensure sufficient space within the mounting hole 12 so that the body 21 of the mounting member 2 can deform under stress, the thickness of the insertion portion 211 of each of the plurality of mounting members 2 is less than the height of the corresponding first portion 121 in the direction Z pointing from the first side surface 1211 to the mounting side surface 11. In this way, when the body 21 of the mounting member 2 is under stress, the insertion portion 211 can tilt under stress within the first portion 121. Furthermore, the second portion 122 can extend to the mounting side surface 11 in the direction Z pointing from the first side surface 1211 to the mounting side surface 11.

[0045] It should be noted that returning to the reference... Figure 2 Since the housing 1 also includes a connecting side 15 opposite to the mounting side 11, multiple mounting holes 12 and multiple snap-fit ​​pieces 13 can also be provided near the connecting side 15 of the housing 1, with each snap-fit ​​piece 13 disposed within a corresponding mounting hole 12. It can be understood that the multiple snap-fit ​​pieces 13 near the connecting side 15 and the multiple snap-fit ​​pieces 13 near the mounting side 11 can be symmetrically arranged, thereby allowing the electrical switch 100 to be installed horizontally in the electrical cabinet 200 in the opposite direction.

[0046] Figure 6 A cross-sectional view of an electrical switch 100 according to some embodiments of the present disclosure is shown. For example... Figure 3 and Figure 6 As shown, in some embodiments, the housing 1 may further include a limiting member 14. The stationary contact 3 can pass through the housing 1. The limiting member 14 may be disposed on one side of the stationary contact 3, and the other side of the stationary contact 3 is adapted to accommodate a terminal block 300. The terminal nut 6 may be disposed within the limiting member 14 and adapted to abut against the stationary contact 3. The terminal 4 passes sequentially through the gasket 5, the terminal block 300, the stationary contact 3, the limiting member 14, and the terminal nut 6 and is adapted to be locked by the terminal nut 6, thereby realizing the wiring process.

[0047] Figure 7A schematic diagram of the wiring nut 6 of an electrical switch 100 according to some embodiments of the present disclosure is shown. For example... Figure 6 and Figure 7 As shown, in some embodiments, the terminal nut 6 may include a connecting portion 61. Correspondingly, the limiting member 14 may include a connecting hole 141, through which the connecting portion 61 is adapted to pass and embed into the stationary contact 3. In this way, the contact area of ​​the stationary contact 3 can be increased, the contact resistance can be reduced, and thus the temperature rise can be reduced.

[0048] To facilitate the embedding of the connecting part 61 into the stationary contact 3, thereby reducing contact resistance, for example, refer to Figure 6 and Figure 7 Furthermore, the connecting portion 61 may include an insert ring 611 adapted to be embedded in the stationary contact 3, wherein the diameter of the insert ring 611 gradually decreases along the Y direction from the connecting portion 61 to the stationary contact 3. (Continue referring to...) Figure 3 and Figure 6 As can be seen, the direction Y of the connecting part 61 pointing towards the stationary contact 3 is one of the directions of the first direction X. It should be understood that in other embodiments, the connecting part 61 may also adopt any other suitable structure so that the connecting part 61 can be embedded in the stationary contact 3.

[0049] Continue to refer to Figure 6 and Figure 7 In some embodiments, the wiring nut 6 may further include a limiting portion 62. The limiting portion 62 may be disposed on the side of the connecting portion 61 opposite to the stationary contact 3. Correspondingly, the limiting member 14 may include a limiting step 142, and the limiting portion 62 may abut against the limiting step 142. In this way, the limiting member 14 can limit the stationary contact 3 and resist the positional change of the stationary contact 3 due to external force.

[0050] Continue to refer to Figure 2 , Figure 3 as well as Figure 6 As shown, because the connector 4 is located deep within the electrical cabinet 200 and close to the inner side of the electrical cabinet 200, there is insufficient operating space, making it difficult to drive the connector 4 with wiring tools, thus making forward wiring difficult to achieve.

[0051] Based on this, the electrical switch 100 according to the embodiments of this disclosure adopts a reverse wiring method, that is, the wiring process is achieved by driving the wiring nut 6 with a wiring tool. To facilitate the driving of the wiring nut 6 by the wiring tool, please continue to refer to... Figure 6 and Figure 7In some embodiments, the wiring nut 6 may further include a mating portion 63. The mating portion 63 can be driven by a wiring tool, and the mating portion 63 may be disposed on the side of the limiting portion 62 away from the stationary contact 3. Furthermore, when there is sufficient operating space, the electrical switch 100 according to the embodiments of this disclosure can also be compatible with forward wiring, which is beneficial for cost control while maintaining the original installation habits and convenience.

[0052] Furthermore, the mating part 63 includes multiple mating surfaces 631. 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, or quantities are possible. For example, depending on the specific application scenario and requirements, the mating part 63 may include six mating surfaces 631. Adjacent mating surfaces 631 of the six mating surfaces 631 are connected to each other, and two mating surfaces 631 of the six mating surfaces 631 are arranged opposite each other.

[0053] Continue to refer to Figure 3 and Figure 6 In some embodiments, the mounting cap 7 may enclose the wiring nut 6 and be snapped into the retaining member 14. The mounting cap 7 is made of insulating material, and in reverse wiring schemes, the mounting cap 7 can increase the creepage path, thereby ensuring the insulation performance of the product.

[0054] The structural design according to embodiments of this disclosure can be applied to various electrical switches, such as circuit breakers, to at least partially solve the aforementioned problems. It should be understood that the structural design according to embodiments of this disclosure can also be applied to other electrical components, and the embodiments of this disclosure do not limit this application.

[0055] 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.
