Description

Technical Field

[0001] This invention relates to the field of switch technology, and more specifically, to an operating device for a rotary switch and a rotary switch. Background Technology

[0002] The term "switch" is defined as turning on and off; it refers to a component that can open a circuit, interrupt current, or divert it to another circuit. The most common switches are manually operated electromechanical devices with one or more contacts. A "closed" switch means the contacts are conducting, allowing current to flow; an "open" switch means the contacts are not conducting, forming an open circuit and preventing current from flowing. The history of switches has evolved from manually operated knife switches to today's intelligent switches used in various large-scale electrical control equipment. Switches have become increasingly functional and safer. Rotary switches, as a common type of switch, prevent unauthorized operation by locking the rotary switch's operating mechanism in a specific position corresponding to a specific state of the rotary operating mechanism.

[0003] With technological advancements, especially in photovoltaic systems, there is a growing demand for remote switching functionality of rotary switches. For example, in the event of a fire in a photovoltaic panel, remote control is needed to disconnect the circuit. Typically, a rotary switch requires a reset operation after remote switching before subsequent switching actions can occur. In existing technology, to facilitate the reset of the circuit breaker's trip unit and prevent interference with its normal opening and closing, the trip unit's reset button is usually activated before opening or closing. However, if a reset operation is not performed or fails before the rotary switch is activated to control the circuit breaker to close or open, the automatic opening and closing function will fail. Summary of the Invention

[0015] Optionally, the drive handle also includes a handheld end connected to the rotating end.

[0016] Optionally, the abutment includes an annular part and a pressure rod connected to the annular part. The annular part is sleeved on the rotating end.

[0017] Optionally, the guide groove includes two guide grooves, which are respectively opened on the fixing member.

The locked position restricts the rotation of the actuating element. When the actuating element is in the working position, the trip unit can be reset by the action of the actuating element. In this way, before the trip unit is reset, the actuating element cannot rotate due to the restriction of the locked position; when the actuating element disengages from the locked position and enters the working position, it acts on the trip unit, causing the trip unit to reset. Therefore, compared with the prior art, this application can achieve rotation to control the opening and closing of the circuit breaker after the trip unit is reset, thereby ensuring reliable reset of the trip unit and avoiding the problem of opening and closing failure caused by rotation operation before the trip unit is reset.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Please refer to Figure 1 and Figure 9 This embodiment provides an operating device for a rotary switch. The operating device includes an actuating element and a fixing element 20 having a receiving cavity 21. The actuating element passes through the receiving cavity 21. The actuating element is driven to move within the receiving cavity 21. The actuating element can switch between a locked position and a working position. The locked position restricts the rotation of the actuating element. When the actuating element is in the working position, the trip unit 60 can be reset under the action of the actuating element.

[0043] It should be noted that the rotary switch operating device provided in this embodiment not only has the function of controlling the operation of the circuit breaker's operating mechanism, but also has the function of resetting the trip unit 60 before controlling the operation of the operating mechanism. For example, in this embodiment, the end of the aforementioned actuating element near the circuit breaker may also be provided with a mating part 12, so that the rotary switch operating device can cooperate with the circuit breaker's operating mechanism through the mating part 12, thereby realizing the opening or closing action of the circuit breaker. It should be understood that the rotary switch operating device controlling the operation of the circuit breaker's operating mechanism is a basic function. The aforementioned method of the rotary switch operating device controlling the operation of the circuit breaker's operating mechanism is only one example of this embodiment and is not a specific limitation on this implementation method. Those skilled in the art can choose any feasible implementation method, as long as the rotary switch operating device can control the operation of the operating mechanism to perform opening or closing.

[0044] In this embodiment, the driving actuator moves within the receiving cavity 21, and the actuator can switch between a locked position and a working position. The locked position restricts the rotation of the actuator; when the actuator is in the working position, the trip unit 60 can be reset by the action of the actuator. Specifically, the locked position restricts the rotation of the actuator, and when the operating device of the rotary switch moves from the locked position to the working position, the trip unit 60 can be reset by the action of the actuator. At this time, the actuator is also unlocked, meaning it can rotate. Therefore, in this embodiment, the rotation of the actuator can be restricted before the trip unit 60 resets, and the actuator can only rotate after the actuator is in the working position and the trip unit 60 resets.

[0045] In summary, this embodiment provides an operating device for a rotary switch. The operating device includes an actuating element and a fixing element 20 with a receiving cavity 21, the actuating element passing through the receiving cavity 21. The actuating element is driven to move within the receiving cavity 21, and can switch between a locked position and a working position. The locked position restricts the rotation of the actuating element; when the actuating element is in the working position, the trip unit 60 can be reset by the action of the actuating element. In this way, before the trip unit 60 is reset, the actuating element cannot rotate due to the restriction of the locked position; when the actuating element disengages from the locked position and enters the working position, it acts on the trip unit 60, causing the trip unit to reset. Therefore, compared with the prior art, this application can achieve rotation to control the opening and closing of the circuit breaker after the trip unit 60 is reset, thereby ensuring a reliable reset of the trip unit 60 and avoiding the problem of failure to open or close the circuit breaker due to rotation before the trip unit 60 is reset.

[0046] This application can prevent the trip unit 60 from rotating before it is reset, thus avoiding the failure of opening and closing due to rotational operation. Of course, in other embodiments of this application, the trip unit 60 can also be prevented from rotating before it is reset, thus avoiding the failure of opening and closing due to rotational operation. In this case, the trip unit can rotate but cannot act on the operating mechanism of the circuit breaker.

[0047] The aforementioned trip unit 60, before being reset, restricts the rotation of its actuator to prevent it from rotating and causing opening / closing failures. This can be achieved in various ways, such as by restricting the rotation of the actuator's drive handle 10, by restricting the rotation of the actuator's abutment 30, or by restricting the rotation of the actuator through the structure of the fixing member, etc.

[0048] For example, when the rotation of the abutment 30 is restricted, it can be achieved by restricting the rotation of the abutment 30 before the trip unit 60 resets. This can include at least two implementations: first, by restricting the rotation of the end of the abutment 30 near the trip unit 60 (for example, the end of the abutment 30 near the trip unit 60 can only rotate freely after the trip unit 60 is reset); second, by restricting the rotation of the end of the abutment 30 near the drive handle 10 (for example, the end of the abutment 30 near the drive handle 10 can only rotate freely after the trip unit 60 is reset). This application does not limit the specific implementation; it only requires that the rotational action of the rotary switch's operating device be locked before the trip unit 60 resets, and unlocked after the trip unit 60 resets. There are various ways in which the rotary switch's operating device can jam when driving the circuit breaker to close, and these will not be listed here.

[0049] The following embodiment will be illustrated by taking the form of limiting the rotation of the drive handle 10 of the actuator before the trip unit 60 is reset.

[0050] The aforementioned actuators include a drive handle 10 and a retaining member 30. The rotating end of the drive handle 10 passes through the receiving cavity 21; the retaining member 30 is sleeved on the rotating end 14 of the drive handle 10, pushing the drive handle 10 to move along the axis of the receiving cavity 21. The drive handle 10 can switch between a locked position and a working position. The locked position restricts the rotation of the drive handle 10. When the drive handle 10 is in the working position, the retaining member 30 acts on the trip unit 60 of the circuit breaker, and the drive handle 10 can rotate relative to the fixed member 20 to control the opening or closing of the circuit breaker. This rotary switch operating device can reliably reset the trip unit 60.

[0051] The aforementioned drive handle 10 is used to rotate within the receiving cavity 21 of the fixing member 20 or to move along the central axis of the receiving cavity 21. When the drive handle 10 rotates within the receiving cavity 21 of the fixing member 20, it can control the circuit breaker to open or close. For example, a mating part 12 can be provided correspondingly at the rotating end 14 of the drive handle 10, so that the operating device of the rotary switch can cooperate with the operating mechanism of the circuit breaker through the mating part 12, thereby realizing the opening or closing action of the circuit breaker. For example, the mating part 12 of the operating device of the rotary switch can be a square hole, and correspondingly, the operating mechanism of the circuit breaker can be provided with a square shaft corresponding to the square hole, so that the control purpose of the operating device of the rotary switch on the circuit breaker can be realized through the cooperation of the square hole and the square shaft. It should be understood that the above-mentioned square hole and square shaft are only one example given in this application. In other embodiments, the relative positions of the square hole and the square shaft can be interchanged, or other mating structures can be used.

[0052] In addition, when the drive handle 10 moves along the central axis of the receiving cavity 21, the drive handle 10 can control the movement of the abutment 30, thereby causing the abutment 30 to move relative to the fixed member 20 (the direction of movement here is along the axis of the receiving cavity 21).

[0053] For example, in this embodiment, the aforementioned abutment 30 is sleeved on the rotating end 14 of the drive handle 10. Since the two are sleeved, there is no radial restriction between the drive handle 10 and the abutment 30, and the drive handle 10 can rotate relative to the abutment 30.

[0054] In this embodiment, by pushing the drive handle 10, the drive handle 10 moves along the axis of the receiving cavity 21, thus allowing the drive handle 10 to switch between a locked position and a working position. When the drive handle 10 is in the locked position, the drive handle 10 is radially locked, and the drive handle 10 can move axially but cannot move radially (here, axial or radial refers to...). Figure 2 or Figure 3(The orientation shown is primary, the same below); When the drive handle 10 is pushed to move along the axis of the receiving cavity 21, the drive handle 10 can switch between the locked position and the working position. When the drive handle 10 moves from the locked position to the working position, the abutment 30 can act on the trip unit 60 of the circuit breaker, thereby causing the abutment 30 to drive the trip unit 60 to reset. At this time, the drive handle 10 can rotate relative to the fixed member 20, thereby controlling the circuit breaker to open or close. In this way, in this embodiment, when the drive handle 10 is in the locked position, the drive handle 10 cannot rotate; only after the drive handle 10 enters the working position, when the abutment 30 acts on the trip unit 60 of the circuit breaker, thereby controlling the trip unit 60 to reset, can the drive handle 10 rotate relative to the fixed member 20, thereby controlling the circuit breaker to open or close through the rotation of the drive handle 10. This can effectively solve the problem in the prior art where the circuit breaker is operated to open or close before the trip unit 60 is reset, resulting in the failure of opening and closing.

[0055] In summary, during use, the drive handle 10 can be moved along the axis of the receiving cavity 21, causing it to move from the locked position to the working position. This allows the holding member 30 to act on the circuit breaker's trip unit 60 under the drive of the drive handle 10, resetting the trip unit 60. This allows the drive handle 10 to rotate relative to the fixed member 20, thereby controlling the circuit breaker's opening and closing. Thus, this embodiment allows the rotary switch's operating device to reset the trip unit 60 immediately after moving from the locked position to the working position, and then rotate the drive handle 10 relative to the fixed member 20 to control the circuit breaker's opening or closing. Compared to existing technologies, this application allows the trip unit 60 to be reset before rotation to control the circuit breaker's opening and closing, ensuring reliable reset of the trip unit 60 and avoiding the problem of failure caused by rotation before the trip unit 60 is reset.

[0056] Please refer to the reference again. Figure 4 and Figure 5 Optionally, a guide channel 23 is also provided on the inner wall of the receiving cavity 21. The guide channel 23 includes a first vertical groove 231 and a first stroke groove 232 communicating with the first vertical groove 231. The first stroke groove 232 is set at an angle to the first vertical groove 231. A guide member 11 is provided on the outer wall of the drive handle 10. The guide member 11 is engaged in the guide channel 23. When the guide member 11 is engaged in the first vertical groove 231, the drive handle 10 is in the locked position; when the guide member 11 is engaged in the first stroke groove 232, the drive handle 10 is in the working position.

[0057] Thus, when the guide member 11 is engaged in the first vertical groove 231, the drive handle 10 is in the locked position, and the drive handle 10 cannot rotate due to the presence of the guide member 11; when the guide member 11 is engaged in the first stroke groove 232, the drive handle 10 is in the working position, and the guide member 11 can move along the first stroke groove 232, allowing the drive handle 10 to rotate relative to the fixed member 20. It should be noted that in this embodiment, when the guide member 11 moves from the end of the first vertical groove 231 away from the first stroke groove 232 to the junction of the first vertical groove 231 and the first stroke groove 232, the drive handle 10 drives the abutment member 30, allowing the abutment member 30 to act precisely on the trip unit 60 (when the trip unit 60 is reset by the reset button 61, then it is the reset button 61; the same applies to other descriptions). Specifically, the length of the first vertical groove 231 should be reasonably selected according to the actual situation, which will not be elaborated further in this application.

[0058] It should be noted that the aforementioned guide channel 23 is only one embodiment of this application. In other embodiments, other implementation methods can be used to switch the drive handle 10 between the locked position and the working position, so that when the drive handle 10 is in the working position, the holding member 30 acts on the trip unit 60 of the circuit breaker, and the drive handle 10 can rotate relative to the fixed member 20 to control the opening or closing of the circuit breaker. For example, the guide member 11 can also be set on the fixed member 20, and the guide channel 23 can be set on the drive handle 10. The specific method is not limited in this application.

[0059] Optionally, the first stroke groove 232 is perpendicular to the first vertical groove 231. In this way, the movement of the drive handle 10 relative to the fixed member 20 and its rotation relative to the fixed member 20 will not interfere with each other, making it easier to operate.

[0060] To ensure that the drive handle 10 can be easily reset after rotation, thus avoiding affecting the next operation of the rotary switch, in this embodiment, optionally, a reset groove 24 is also provided on the inner wall of the receiving cavity 21. The reset groove 24 is connected between the first vertical groove 231 and the first stroke groove 232, and is used to reset the guide member 11.

[0061] For example, in one embodiment, the reset slot 24 includes a second vertical slot 241 and a second travel slot 242 that are interconnected. The second vertical slot 241 connects the first travel slot 232 and the second travel slot 242, and the second travel slot 242 connects the second vertical slot 241 and the first vertical slot 231. In this way, the guide member 11 can be reset sequentially through the second vertical slot 241 and the second travel slot 242, thereby preparing for the next press of the reset button 61 to control the trip unit 60 to reset. Optionally, in this embodiment, the first travel slot 232 and the second travel slot 242 are arranged in parallel.

[0062] For example, in another embodiment, the reset groove 24 can also be an inclined groove, one end of which connects to the end of the first stroke groove 232 away from the first vertical groove 231, and the other end of which connects to the end of the first vertical groove 231 away from the first stroke groove 232. This also facilitates the rapid reset of the drive handle 10.

[0063] In addition, in this embodiment, to ensure smoother and more reliable rotation or movement of the drive handle 10 relative to the fixed member 20, the aforementioned guide channel 23 may include two channels, symmetrically arranged on the inner wall of the receiving cavity 21. Similarly, two guide members 11 may be included, symmetrically arranged on the outer wall of the drive handle 10. It should be understood that each set of guide members 11 and guide channel 23 should be compatible. During movement, the two guide members 11 should move in the same direction.

[0064] Optionally, to facilitate the rapid reset of the drive handle 10, the fixing member 20 is provided with a first protrusion 25 extending from the inner wall of the receiving cavity 21 toward the handle, and a second protrusion is provided on the outer wall of the rotating end 14. The operating device of the rotary switch also includes a spring, which is sleeved on the rotating end 14, with one end abutting against the first protrusion 25 and the other end abutting against the second protrusion. Here, it should be understood that the spring should be set to avoid interfering with the guide channel 23. The specific setting position should be reasonably selected by those skilled in the art based on the actual setting of the guide channel 23 and the guide member 11, and will not be described in detail in this application.

[0065] Please refer to the reference again. Figure 6 As shown, optionally, the drive handle 10 also includes a handheld end 13 connected to the rotating end 14, wherein the handheld end 13 is for easy manual gripping to drive the transmission end. In this way, the rotating end 14 of the drive handle 10 can be easily controlled during actual operation.

[0066] Please refer to the reference again. Figure 7 and Figure 8 Optionally, the supporting member 30 includes an annular member 31 and a pressure rod 32 connected to the annular member 31. The annular member 31 is sleeved on the rotating end 14. The fixing member 20 has a guide groove 22 on the side near the supporting member 30. The pressure rod 32 extends beyond the fixing member 20 through the guide groove 22 and acts on the trip unit 60. In this way, the supporting member 30 can move closer to or further away from the fixing member 20 by moving within the guide groove 22 via the pressure rod 32.

[0067] To ensure greater stability when the abutment 30 moves relative to the fixing member 20, in this embodiment, optionally, two guide grooves 22 are provided, each on the fixing member 20. The pressure rod 32 includes a first sub-rod 321 and a second sub-rod 322, which are located on opposite sides of the annular member 31 (i.e., the first sub-rod 321 and the second sub-rod 322 are symmetrically arranged on both sides of the annular member 31). The first sub-rod 321 and the second sub-rod 322 are correspondingly engaged in the two guide grooves 22, and the second sub-rod 322 is used to act on the trip unit 60.

[0068] Optionally, a sealing ring 141 is fitted onto the outer wall of the rotating end 14, and the sealing ring 141 is located between the handheld end 13 and the supporting member 30. Additionally, a gasket may be fitted onto the outer wall of the rotating end 14, and the gasket is located on the side of the sealing ring 141 away from the supporting member 30. This facilitates the sealing of the rotary switch operating device relative to the cabinet (which can be used to fix the rotary switch operating device).

[0069] In addition, in order to facilitate the fixing of the rotary switch operating device relative to the cabinet, in this embodiment, the rotary switch operating device may also include a nut 40. Correspondingly, the outer wall of the fixing member 20 may also be provided with a thread that matches the nut 40. In this way, the rotary switch operating device can be installed on the cabinet through the nut 40.

[0070] In this embodiment, the drive handle 10 can drive the abutment 30 to move relative to the fixed member 20, and the drive handle 10 can rotate relative to the abutment 30. Therefore, there is an axial constraint but no radial constraint between the abutment 30 and the fixed member 20. Optionally, the rotating end 14 may also include a retaining ring 50 and a blocking portion 142, which are respectively disposed on opposite sides of the annular member 31 to limit the axial movement of the annular member 31 relative to the rotating end 14 of the drive handle 10.

[0071] Another aspect of the present invention is described in conjunction with reference to...
