[0002] Electrical switches, such as circuit breakers, serve as protective switches, requiring the ability to carry and interrupt corresponding currents. Electrical switches can cut off current in the event of overload, short circuit, or leakage faults in a circuit, thereby protecting the safety of lines and equipment. The operating handles of electrical switches are suitable for connection to electrically operated devices, which allow switching between remote opening / closing, manual opening / closing, and opening / closing lockout functions.

[0012] In some embodiments, the locking member includes a limiting portion, and the conversion member further has a first side, wherein when the conversion member is in the second position, the limiting portion is spaced apart from the first side to allow the limiting portion to rotate out of the first hole, the limiting portion being adapted to rotate out of the first hole and be blocked by the housing.

[0013] In some embodiments, the locking member includes a rotating portion rotatably connected to the housing via a pin, the rotating portion having a locking hole, wherein when the conversion member is in the third position, the locking hole rotates out of the housing and is adapted to be padlocked.

[0019] As described above, electrical switches are typically connected to electrically operated devices that switch the switch between remote opening / closing, manual opening / closing, and opening / closing lockout functions. However, conventional electrically operated devices are complex in structure, occupy a large space, and are cumbersome to operate. Embodiments of this disclosure provide an electrically operated device for electrical switches to at least partially solve the above-mentioned problems. In the following, [further details will be provided]. Figures 1 to 10 The principles of this disclosure are described.

[0020] Figure 1 A schematic diagram of the structure of an electric operating device 100 and an electrical switch 200 according to some embodiments of the present disclosure is shown. Figure 2 A schematic diagram of the structure of an electric operating device 100 according to some embodiments of the present disclosure is shown. Figure 3 A partial structural schematic diagram of an electrically operated device 100 according to some embodiments of the present disclosure is shown. Figure 4 A schematic diagram of the structure of the converter 4 and the locking member 5 according to some embodiments of the present disclosure is shown. Figure 5 and Figure 6 A schematic diagram of the structure of the converter 4 according to some embodiments of the present disclosure is shown. Figure 7 A schematic diagram of the engagement of the conversion element 4 and the housing 1 according to some embodiments of the present disclosure is shown. Figure 2 and Figure 7 The converter 4 shown is in the first position. (As shown) Figures 1 to 7 As shown, the electric operating device 100 described herein includes a housing 1, a circuit breaker handle 2, an actuator (not shown), a control module 3, a switching element 4, and a locking element 5.

[0021] refer to Figure 1 In some embodiments, the moving contact assembly (not shown) is disposed outside the housing 1 and located within an electrical switch 200, such as a circuit breaker. The electrical switch 200 may be disposed on the outer surface of the housing 1. The operating handle 201 of the electrical switch 200 is adapted to be connected to the moving contact assembly via an intermediate mechanism (not shown) to drive the moving contact assembly. When driven, the moving contact assembly is adapted to move toward or away from the stationary contact assembly (not shown) to switch between a closed position and an open position. When the moving contact assembly is in the closed position, the moving contact assembly and the stationary contact assembly are connected, and the main circuit of the electrical switch 200 is open. When the moving contact assembly is in the open position, the moving contact assembly and the stationary contact assembly are disconnected, and the main circuit of the electrical switch 200 is closed.

[0022] refer to Figure 1 and Figure 2 In some embodiments, the closing / opening handle 2 is rotatably connected to the housing 1 and adapted to be coupled to the moving contact assembly. The closing / opening handle 2 is adapted to drive the electrical switch to open or close when activated. For example, the closing / opening handle 2 is connected to the operating handle 201, which is connected to the moving contact assembly via an intermediate mechanism. In this way, during manual operation of the closing / opening handle 2, the closing / opening handle 2 is adapted to drive the operating handle 201 and the moving contact assembly, thereby switching the moving contact assembly between a closed position and an open position to complete the manual closing / opening operation.

[0023] refer to Figure 1 and Figure 2 In some embodiments, an actuator, such as a motor, may be housed within the housing 1 and coupled to the closing / opening handle 2. For example, the actuator and the closing / opening handle 2 are driven by gear meshing. The actuator is adapted to drive the closing / opening handle actuated when activated, thereby opening or closing the electrical switch 200, thus switching the moving contact assembly between the closed and open positions. For example, the actuator is connected to the closing / opening handle 2, which is connected to the operating handle 201. The operating handle 201 is connected to the moving contact assembly via an intermediate mechanism. In this manner, when the actuator drives the closing / opening handle 2 actuated, the closing / opening handle 2 is adapted to drive the operating handle 201 and the moving contact assembly.

[0024] refer to Figure 7 The control module 3 is housed within the housing 1 and includes a circuit board 32 and electronic components 31 mounted on the circuit board 32. The control module 3 can be electrically connected to a remote device via the electronic components 31, allowing communication between the control module 3 and the remote device to be determined by whether the electronic components 31 are triggered. For example, the electronic components 31 have a first untriggered state and a second triggered state. Furthermore, the control module 3 is also electrically connected to an actuator. In this manner, when the electronic components 31 are in the second state, they are triggered, and the control module 3 is electrically connected to the remote device. The control module 3 is adapted to receive external signals (e.g., opening / closing signals) from the remote device and control the actuator to actuate, thereby driving the opening / closing handle 2 to actuate, which in turn drives the moving contact assembly to complete the remote opening / closing operation. When the electronic components 31 are in the first state, they are not triggered, disconnecting the control module 3 from the remote device. The control module 3 is disconnected from the remote device and cannot communicate, locking the remote opening / closing functions of the electric operating device 100 and the electrical switch 200.

[0025] refer to Figure 3 In some embodiments, the switching element 4 is movably connected to the housing 1. The switching element 4 is movable in directions toward and away from the opening / closing handle 2. During movement toward the opening / closing handle 2, the switching element 4 is adapted to switch between a first position, a second position, and a third position, and the switching element 4 moves closer to the opening / closing handle 2. During movement away from the opening / closing handle 2, the switching element 4 is adapted to switch between a third position, a second position, and a first position, and the switching element 4 moves further away from the opening / closing handle 2.

[0026] refer to Figure 3 and Figure 4In some embodiments, the locking member 5 is rotatably connected to the housing 1 and located on the path of the switching member 4 toward the opening / closing handle 2. In this way, during the movement of the switching member 4 toward the opening / closing handle 2, i.e., during the switching from the first position to the third position, the locking member 5 is adapted to be driven by the switching member 4 to rotate relative to the housing 1. During the movement of the switching member 4 away from the opening / closing handle 2, the locking member 5 is released and reset by the switching member 4.

[0027] Figures 8 to 10 The schematic operation of an electrically operated device 100 according to some embodiments of the present disclosure is shown. Figure 8 The converter 4 shown is in the first position. Figure 9 The converter 4 shown is in the second position. Figure 10 The converter 4 shown is in the third position. (As shown) Figures 8 to 10 As shown, the converter 4 is disposed adjacent to the electronic device 31 and is adapted to interact with the electronic device 31 to trigger the electronic device 31. (Reference) Figure 8 When the switching element 4 is in the first position, it triggers the electronic device 31 and puts it into the second state. Furthermore, the switching element 4 is a first distance from the opening / closing handle 2 and is outside the rotation path of the handle 2; therefore, it does not restrict the rotation of the handle 2. In this way, the handle 2 can be driven to activate the manual opening / closing function of the electric operating device 100 and the electrical switch 200, thereby enabling manual opening / closing operations. Additionally, the control module 3 is adapted to receive opening / closing signals from a remote device to activate the remote opening / closing function of the electric operating device 100 and the electrical switch 200, thereby enabling remote opening / closing operations.

[0028] like Figure 9 As shown, when the converter 4 is in the second position, the converter 4 causes the electronic device 31 to be in the first state. Furthermore, the converter 4 is at a second distance from the circuit breaker handle 2 and is outside the rotation path of the circuit breaker handle 2, therefore the converter 4 does not restrict the rotation of the circuit breaker handle 2. The second distance is less than the first distance. In this way, the circuit breaker handle 2 can be driven to activate the manual circuit breaker function of the electric operating device 100 and the electrical switch 200, thereby enabling manual circuit breaker operation. However, the control module 3 cannot receive circuit breaker signals from remote devices, and the remote circuit breaker function of the electric operating device 100 and the electrical switch 200 is locked.

[0029] like Figure 10As shown, when the converter 4 is in the third position, the converter 4 keeps the electronic device 31 in the first state. Furthermore, the converter 4 is positioned above the rotation path of the opening / closing handle 2 to block the opening / closing handle 2, thus restricting the rotation of the opening / closing handle 2 and preventing it from being driven. In this way, both the remote opening / closing function and the manual opening / closing function of the electric operating device 100 and the electrical switch 200 are locked.

[0030] Continue to refer to Figure 10 During the movement of the switching element 4 from the second position to the third position, the switching element 4 drives the locking element 5, and the locking element 5 rotates to a position opposite to the movement path of the switching element 4 away from the opening / closing handle 2. The switching element 4 is limited by the locking element 5 and cannot move away from the opening / closing handle 2. When the locking element 5 is locked, the position of the switching element 4 is also locked.

[0031] According to embodiments of this disclosure, in the first position, the switching element 4 does not restrict the rotation of the opening / closing handle 2, and the electronic device 31 is triggered by the switching element 4 to be in the second state, where the manual opening / closing function and the remote opening / closing function are activated. In the second position, the switching element 4 does not restrict the rotation of the opening / closing handle 2, and the electronic device 31 is in the first state, where the remote opening / closing function is locked and the manual opening / closing function is activated. In the third position, the switching element 4 can restrict the rotation of the opening / closing handle 2, and the electronic device 31 is in the first state, where the remote opening / closing function is locked and the manual opening / closing function is locked. In this way, compared to a conventional electric operating device 100, the electric operating device 100 of this disclosure embodiment only needs to drive the switching element 4 to achieve the switching of the above three functions, which is simple in structure, low in cost, and occupies little space, which is conducive to miniaturization design. In addition, the operation method is simplified, and the drive chain is simple and efficient.

[0032] The electronic device 31 according to the embodiments of this disclosure can be any type of component known now or available in the future, as long as it can interact with the conversion element 4 and switch between two states, thereby connecting or disconnecting the control module 3 from the remote device. The embodiments of this disclosure do not limit this.

[0033] For example, in some embodiments, the electronic device 31 may be an electronic switch. (See reference) Figures 9 to 10 When electronic device 31 is in the first state, it is released by converter 4. Since electronic device 31 is not triggered, control module 3 is disconnected from the remote device and cannot communicate. (Reference) Figure 8 When electronic device 31 is in the second state, it is pressed by the switching element 4. Because electronic device 31 is triggered, control module 3 communicates with a remote device. In other words, electronic device 31 can be triggered when pressed.

[0034] In other embodiments, the electronic device 31 can be an electronic switch. When the electronic device 31 is in a first state, it is pressed by the switching element 4. Since the electronic device 31 is not triggered, the control module 3 is disconnected from the remote device and cannot communicate. When the electronic device 31 is in a second state, it is released by the switching element 4. Since the electronic device 31 is triggered, the control module 3 communicates with the remote device. The electronic device 31 can be triggered upon release.

[0035] It should be noted that, in addition to being triggered by the pressing or releasing operation described above, the electronic device 31 according to the embodiments of this disclosure can also be triggered by other means, and the embodiments of this disclosure do not limit this.

[0036] In the following description, the exemplary structure and principle of the electrically operated device 100 will be mainly described in terms of the triggering of electronic device 31 when it is pressed. Other cases described above are the same or similar, and will not be elaborated upon in this disclosure.

[0037] In some embodiments, reference Figure 2 The housing 1 has an operation window 11. (See reference) Figures 4 to 7 The conversion element 4 may include a main body 41, an operation part 42, and a pressing part 43. The operation part 42 may be provided on the main body 41 and located within the operation window 11, so that the operation part 42 can be pushed through the operation window 11 to drive the conversion element 4 to move. The pressing part 43 may be provided on the side of the main body 41 opposite to the operation window 11, and the pressing part 43 is adapted to press or release the electronic device 31.

[0038] Further reference Figure 8 and Figure 9 The electronic device 31 may include a trigger portion 311, and the pressing portion 43 is adapted to press or release the trigger portion 311. The trigger portion 311 may include, for example, a button. In this way, when the trigger portion 311 is pressed, the electronic device 31 is triggered, and the control module 3 communicates with the remote device. When the trigger portion 311 is released, the electronic device 31 is not triggered, the control module 3 is disconnected from the remote device, and communication is impossible.

[0039] refer to Figures 4 to 6In some embodiments, the main body 41 includes a first portion 411, a second portion 412, and a connecting portion 413. The first portion 411 may face the operation window 11. The second portion 412 is located on the side of the first portion 411 opposite to the operation window 11. The connecting portion 413 is disposed between the first portion 411 and the second portion 412. It can be understood that the first portion 411, the connecting portion 413, and the second portion 412 are disposed along a first direction X, and the first portion 411 and the second portion 412 are spaced apart from each other in the first direction X. The operation portion 42 is disposed on the side of the first portion 411 opposite to the second portion 412, and the pressing portion 43 is disposed on the side of the second portion 412 opposite to the first portion 411. In this way, the conversion member 4 adopts a layered structural design, which is suitable for increasing the size of the conversion member 4 in the first direction X, so as to facilitate the conversion member 4 to drive the electronic device 31 and the opening / closing handle 2 inside the housing 1.

[0040] refer to Figures 4 to 7 In some embodiments, the switching element 4 is movably connected to the housing 1, and the switching element 4 is adapted to move toward and away from the opening / closing handle 2. The housing 1 has a mounting groove 12, a first portion 411 located within the mounting groove 12 and adapted to move within the mounting groove 12 to define the direction of movement of the switching element 4. A second portion 412 is located outside the mounting groove 12. (Continuing to refer to...) Figure 5 and Figure 7 The housing 1 also includes a protrusion 17. The protrusion 17 can form a mounting groove 12 with the side plate of the setting operation window 11 of the housing 1. Correspondingly, the converter 4 is provided with a receiving space 101. Since the converter 4 adopts a layered structural design, a receiving space 101 is also formed between the first part 411 and the second part 412. The receiving space 101 can be arranged on the converter 4 in a direction close to or away from the opening and closing handle 2. The protrusion 17 can be inserted into the receiving space 101 and abut against or be spaced apart from the side of the second part 412 adjacent to the first part 411. It can be understood that when the side of the second part 412 adjacent to the first part 411 abuts against the lower side of the protrusion 17, since the side of the first part 411 adjacent to the first part 412 always abuts against the upper side of the protrusion 17, the protrusion 17 can also limit the movement direction of the converter 4 and support the converter 4.

[0041] Further reference Figure 6 and Figure 7At least one first protrusion 44 is provided on one side of the first part 411 adjacent to the operation window 11. Correspondingly, the housing 1 also includes a second protrusion 131 and a third protrusion 132 disposed in the mounting groove 12. At least one first protrusion 44 can interact with the second protrusion 131 or the third protrusion 132 to improve the tactile feedback during user operation through resistance, thereby prompting the user through tactile feedback that the switching element 4 has switched positions.

[0042] refer to Figure 2 , Figure 6 and Figure 7 When the switching element 4 is in the first position, the side of the operating part 42 facing away from the opening / closing handle 2 abuts against the wall of the operating window 11, and the first protrusion 44 abuts against the second protrusion 131. In this way, the switching element 4 is limited in the movement direction, so that the switching element 4 is held in the first position. When the switching element 4 is in the second position, the first protrusion 44 may be located between the second protrusion 131 and the third protrusion 132. In this way, the switching element 4 is limited in the movement direction, so that the switching element 4 is held in the second position. When the switching element 4 is in the third position, the side of the operating part 42 adjacent to the opening / closing handle 2 abuts against the wall of the operating window 11, and the first protrusion 44 abuts against the third protrusion 132. In this way, the switching element 4 is limited in the movement direction, so that the switching element 4 is held in the third position.

[0043] Continue to refer to Figure 2 In some embodiments, the housing 1 may further include a first indicator mark 14, a second indicator mark 15, and a third indicator mark 16 disposed adjacent to the operation window 11. When the converter 4 is in the first position, the operation portion 42 is aligned with the first indicator mark 14 to indicate that the converter 4 is in the first position. When the converter 4 is in the second position, the operation portion 42 is aligned with the second indicator mark 15 to indicate that the converter 4 is in the second position. When the converter 4 is in the third position, the operation portion 42 is aligned with the third indicator mark 16 to indicate that the converter 4 is in the third position.

[0044] The indicator marks according to the embodiments of this disclosure may be combinations of different numbers, different letters, or different colors, and the embodiments of this disclosure do not limit this.

[0045] refer to Figure 5 and Figure 10In some embodiments, the second portion 412 has a first end 4121 adjacent to the opening / closing handle 2. The switching member 4 also includes a mating portion 45, which may be disposed at the first end 4121. Correspondingly, the opening / closing handle 2 has a mating groove 21. The mating portion 45 engages with the mating groove 21 to restrict rotation of the opening / closing handle 2. For example, when the switching member 4 is in the third position, the mating portion 45 is located within the mating groove 21 of the opening / closing handle 2. In this way, the switching member 4 is adapted to prevent rotation of the opening / closing handle 2. (See reference...) Figure 5 , Figure 8 and Figure 9 When the switching element 4 is in the first position and the second position, the mating part 45 and the mating groove 21 of the opening and closing handle 2 are spaced apart from each other to allow the opening and closing handle 2 to rotate.

[0046] In some embodiments, reference Figure 8 The locking element 5 is rotatably connected to the housing 1 via a pin 61. A torsion spring 62 may be mounted on the pin 61. One end of the torsion spring 62 can be connected to the locking element 5, and the other end can be connected to the housing 1. (Reference) Figures 7 to 9 With the converter 4 in the first and second positions, the locking member 5 is located inside the housing 1, and the torsion spring 62 is adapted to hold the locking member 5 in a position where its upper surface is flush with the upper surface of the housing 1. (Reference) Figure 10 When the converter 4 is in the third position, the locking element 5 is driven by the converter 4 and rotates at least partially outside the housing 1, and the locking element 5 can be padlocked.

[0047] refer to Figure 4 and Figure 5 In some embodiments, the second portion 412 further has a second end 4122 facing away from the opening / closing handle 2. The main body 41 may also include a drive portion 414. The drive portion 414 is located at the second end 4122 and is disposed on one side of the second portion 412 adjacent to the operating window 11. The drive portion 414 may also be connected to the first portion 411. A locking member 5 is located on the path of movement of the drive portion 414 toward the opening / closing handle 2. (See reference...) Figures 8 to 10 During the movement of the switching element 4 toward the opening / closing handle 2, the driving part 414 is adapted to contact and drive the locking element 5 to rotate counterclockwise. During the rotation of the locking element 5, the torsion spring 62 is adapted to be subjected to force and deform in preparation for the locking element 5 to reset.

[0048] Return to reference Figure 4 In some embodiments, the second portion 412 further includes a first hole 4123 and a second hole 4124. The second hole 4124 is further away from the opening / closing handle 2 than the first hole 4123. (Continue referring to...) Figure 4 , Figure 8 and Figure 9With the converter 4 in the first and second positions, a portion of the locking member 5 passes through the first hole 4123. (Continue to refer to...) Figure 4 and Figure 10 When the switching element 4 is in the third position, the locking element 5 rotates so that its other part is inserted into the second hole 4124 and rotates out of the first hole 4123. On the one hand, by providing the first hole 4123 and the second hole 4124 on the main body 41, interference between the locking element 5 and the switching element 4 during rotation is avoided, and the size of the combined switching element 4 and locking element 5 is reduced. On the other hand, since the locking element 5 can be inserted into the second hole 4124, the locking element 5 is located on the path of the switching element 4 away from the movement of the opening / closing handle 2, thus preventing the switching element 4 from moving away from the opening / closing handle 2.

[0049] refer to Figure 4 and Figures 8 to 10 In some embodiments, the locking member 5 includes a limiting portion 53. The second part 412 also includes a first side 4125 disposed opposite to the operation window 11. When the switching member 4 is in the first position and the second position, the limiting portion 53 of the locking member 5 is spaced apart from the first side 4125. It is understood that during the switching process of the switching member 4 from the second position to the third position, the locking member 5 needs to rotate out of the first hole 4123. By providing a gap between the locking member 5 and the first side 4125, interference between the locking member 5 and the switching member 4 during rotation is avoided, thereby facilitating the rotation of the locking member 5.

[0050] refer to Figure 4 and Figure 10 In some embodiments, the locking member 5 may include a rotating part 51. The rotating part 51 is rotatably connected to the housing 1 via a pin 61. The rotating part 51 has a locking hole 511. When the converter 4 is in the third position, the locking hole 511 rotates out of the housing 1 and is adapted to be padlocked. In this way, the locking member 5 can be locked, and the converter 4 cannot move away from the opening / closing handle 2 to press the electronic device 31 or be pulled out from the mating groove 21 of the opening / closing handle 2, thus preventing the electrical switch 200 from being accidentally opened or closed due to user misoperation, thereby improving the safety of the electrical switch 200.

[0051] Continue to refer to Figure 4 and Figure 5 In some embodiments, the locking member 5 may further include an actuating part 52. The actuating part 52 is disposed on the rotating part 51. The actuating part 52 is located on the path of movement of the drive part 414 of the switching member 4 toward the opening / closing handle 2, and is adapted to be driven by the drive part 414 to rotate into the second hole 4124, causing the locking member 5 to rotate at least partially outside the housing 1, and the locking member 5 can be padlocked. Specifically, referring to... Figure 4 , Figure 5 and Figure 8 With the converter 4 in the first position, the actuating part 52 is spaced apart from the driving part 414 and located outside the second hole 4124. (Continue to refer to...) Figure 4 , Figure 5 and Figure 9 With the converter 4 in the second position, the actuating part 52 initially contacts the driving part 414 and is located outside the second hole 4124. (Continue referring to...) Figure 4 , Figure 5 and Figure 10 When the switching element 4 is in the third position, the actuating part 52 rotates into the second hole 4124, and the actuating part 52 abuts against or is spaced apart from the side wall of the adjacent opening / closing handle 2 of the second hole 4124, to prevent the switching element 4 from switching from the third position to the second position or the first position. In this way, the locking element 5 rotates to be located on the path of movement of the switching element 4 away from the opening / closing handle 2, so as to prevent the switching element 4 from moving away from the opening / closing handle 2.

[0052] It should be noted that continued reference is necessary. Figure 4 , Figure 5 and Figure 9 When the switching member 4 is in the second position, the actuating part 52 can still be spaced a relatively small distance from the driving part 414, that is, the actuating part 52 is about to contact the driving part 414. When the switching member 4 is in the second position, the driving part 414 can also drive the actuating part 52, and the embodiments of this disclosure are not limited in this respect.

[0053] refer to Figure 4 In some embodiments, the limiting part 53 may be provided on the rotating part 51. (Continue referring to...) Figure 4 , Figure 8 and Figure 9 With the conversion element 4 in the first and second positions, the limiting part 53 is partially located within the first hole 4123. (Continue to refer to...) Figure 9 and Figure 10 When the converter 4 is in the third position, the limiting part 53 is adapted to rotate out of the first hole 4123 and be blocked by the housing 1, and the locking part 5 is limited by the housing 1. For example, the end of the limiting part 53 that is away from the rotating part 51 is blocked by the housing 1. In this way, the maximum rotation position of the locking part 5 is limited, preventing the user from continuing to rotate the locking part 5 counterclockwise during the padlock process, which would prevent the locking part 5 from being reset.

[0054] It should be noted that when the converter 4 is in the third position, if the actuating part 52 is still in contact with the side wall of the adjacent opening and closing handle 2 of the second hole 4124, then the locking part 5 is suitable to be blocked by the converter 4 and cannot continue to rotate counterclockwise, thus the locking part 5 is double-limited.
