Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to an operating mechanism and a switch device. Background Art

[0002] A switch device is an electronic component that can open a circuit, interrupt current, or allow current to flow to other circuits. There are multiple contacts inside the switch device, and the switch device can work normally by controlling the contact or separation of the multiple contacts.

[0003] In order to facilitate observation of the use of switch devices, a window is generally provided on the housing of the switch device for visualization. However, when the contacts are separated, the switch device cuts off the current in the circuit, and the voltage between the contacts causes discharge in the air medium, forming an arc. The arc is very likely to burn the window, affecting the visualization of the switch device and even causing a safety accident. Summary of the invention

[0004] The present application provides an operating mechanism and a switch device, which can reduce the impact of electric arc on the visualization of the switch device and reduce the possibility of safety accidents.

[0005] In a first aspect, the present application provides an operating mechanism, which is applied to a switch device. The operating mechanism includes a shell, an isolating member, an operating handle, and an elastic member. The shell has a accommodating chamber inside, and a visual window is provided on the shell, and the visual window passes through the cavity wall of the accommodating chamber. The isolating member is slidably disposed in the accommodating chamber and can be switched between a first position and a second position. The operating handle is rotatably disposed in the accommodating chamber, and is used to control the closing or opening of the switch device. When the operating handle controls the closing of the switch device, the operating handle drives the isolating member to slide from the second position to the first position. The elastic member is located in the accommodating chamber, and the two ends of the elastic member are respectively in contact with the cavity wall of the accommodating chamber and the isolating member. When the operating handle controls the opening of the switch device, the elastic member drives the isolating member to slide from the first position to the second position.

[0006] When the isolating element is located at the first position, the isolating element is misaligned with the visual window, and when the isolating element is located at the second position, the isolating element is opposite to at least a portion of the visual window.

[0007] In the embodiment of the present application, when the switch device is opened, causing an arc to appear in the accommodating chamber, the elastic member can push the isolating member, so that the isolating member slides to the second position. In this way, the isolating member can protect the visual window, reduce the damage of the arc to the visual window, and further reduce the impact of the arc on the visualization of the switch device and the possibility of causing a safety accident.

[0008] Optionally, the operating mechanism has a first direction, and the isolation member can slide along the first direction. The isolation member includes a sliding portion, a connecting portion, and a baffle. In the first direction, the connecting portion has a first end and a second end opposite to each other, the first end is away from the visual window, the sliding portion is connected to the first end, and the baffle is connected to the second end. When the isolation member is in the second position, the baffle is opposite to at least part of the visual window.

[0009] The operating handle is connected with a driving rod, which is located between the sliding part and the baffle. When the operating handle controls the switch device to close, the driving rod pushes the sliding part to make the isolating element slide from the second position to the first position.

[0010] In this way, when the isolation member slides from the first position to the second position, the baffle can first slide to a position opposite to the visible window and shield and protect the visible window.

[0011] Optionally, when the switch device is in the closed state, the operating handle abuts against part of the isolating member. When the operating handle is rotated to control the switch device to switch to the open state, the abutting portion of the operating handle and the isolating member gradually decreases, and when the operating handle is rotated to a first angle, the operating handle is separated from the isolating member, and when the operating handle is rotated to a second angle, the switch device completes the state switching. The first angle is smaller than the second angle.

[0012] In this way, the response speed of the isolating element can be improved, so that the isolating element can cover the visible window at the initial stage of switching the switch device from the closed state to the open state, thereby improving the isolation and blocking effect of the arc.

[0013] Optionally, the housing is further provided with an operating hole spaced apart from the visual window, and the operating hole penetrates the cavity wall of the accommodating cavity. The operating handle includes an operating rod and a connecting piece, the connecting piece is rotatably connected to the cavity wall of the accommodating cavity, the operating rod is connected to the connecting piece, and at least part of the operating rod extends out of the housing through the operating hole, and the operating rod is used to drive the connecting piece to rotate so that the connecting piece controls the switch device to close or open. The driving rod is connected to the side of the connecting piece away from the operating hole.

[0014] In this way, the operating rod can be used as a user-operated part, and the connecting piece can be connected to the moving contact. Thus, when the user controls the operating rod to rotate, the connecting piece can rotate and control the moving contact to move, so that the moving contact contacts or separates from the static contact.

[0015] Optionally, a guide groove extending along the first direction is arranged on the cavity wall of the accommodating cavity, and the sliding part is embedded in the guide groove and can slide in the guide groove.

[0016] Through the above arrangement, on the one hand, the guide groove cooperates with the sliding portion to achieve the installation of the isolation member in the accommodating cavity.

[0017] On the other hand, when the isolating member slides, the guide groove guides the sliding of the sliding portion, thereby reducing the possibility of the isolating member being offset during the sliding process.

[0018] Optionally, a first guide plate and a second guide plate are connected to the cavity wall of the accommodating cavity, the first guide plate and the second guide plate are spaced apart, and both the first guide plate and the second guide plate extend in the first direction. The surface of the first guide plate facing the second guide plate and the surface of the second guide plate facing the first guide plate form a groove wall of the guide groove, and the sliding portion is embedded between the first guide plate and the second guide plate.

[0019] Through the above arrangement, the first guide plate and the second guide plate can cooperate to form a guide groove, and install and guide the sliding part.

[0020] Optionally, the isolation element is a non-transparent structure.

[0021] Through the above arrangement, when the baffle blocks the visible window, the user can observe the colored isolating member through the visible window. Thus, the isolating member can indicate the state of the switch device through its own color.

[0022] Optionally, an indication structure is provided on the isolating member, and when the isolating member is in the second position, at least a portion of the indication structure is opposite to the visible window, and the indication structure is used to indicate that the switching device is in an open state.

[0023] Through the above arrangement, when the baffle blocks the visible window, the user can observe the indication structure through the visible window. In this way, the isolating member can indicate the state of the switch device through the indication structure.

[0024] Optionally, a cover plate is provided on the shell, the cover plate cover is provided on the visual window, and the cover plate is a transparent structure.

[0025] Through the above arrangement, the cover is arranged on the visible window, and the cover can seal the position where the visible window is opened on the shell, thereby reducing the possibility that external dust and the like enter the accommodating cavity through the visible window and affect the operation of the components in the accommodating cavity.

[0026] In a second aspect, the present application provides a switching device, comprising any operating mechanism in the above-mentioned first aspect.

[0027] Optionally, the switch device includes a moving contact and a stationary contact, the moving contact is movably arranged in the accommodating cavity, the stationary contact is fixed in the accommodating cavity, and the visual window is opposite to the stationary contact. The operating handle is connected to the moving contact, and the operating handle can drive the moving contact to move so that the moving contact contacts the stationary contact to close the switch device, or separate the moving contact from the stationary contact to open the switch device.

[0028] The beneficial effects of the switch device provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0047] For example, Figure 1 and Figure 2 As shown, the embodiment of the present application provides a switching device 200, including the above-mentioned Figure 3 The operating mechanism 100 is shown.

[0048] The switch device 200 is an electronic component that can open a circuit, interrupt a current, or allow a current to flow to another circuit. It works by controlling the contact or separation of the internal contacts. When the contacts switch from the contact state to the separation state, an arc is easily formed between the contacts.

[0049] In the switch device 200 equipped with the above-mentioned operating mechanism 100 , a visible window 12 is provided in the operating mechanism 100 for users to observe, and the occurrence of arc burning the visible window 12 can be reduced, thereby reducing the influence of the arc on the visualization of the switch device 200 .

[0050] It should be noted that the switch device 200 proposed in the present application can be different devices, for example, a relay, a contactor, a circuit breaker, a disconnector, a side-mounted accessory (auxiliary contact) connected to a contactor, and the like.

[0051] In some embodiments, Figure 2 and Figure 3 As shown, the switch device 200 may include a moving contact 201 and a stationary contact 202, wherein the moving contact 201 is movably disposed in the accommodating cavity 11, the stationary contact 202 is fixed in the accommodating cavity 11, and the visual window 12 is opposite to the stationary contact 202. The operating handle 30 is connected to the moving contact 201, and the operating handle 30 may drive the moving contact 201 to move, so that the moving contact 201 contacts the stationary contact 202, so that the switch device 200 is closed, or the moving contact 201 is separated from the stationary contact 202, so that the switch device 200 is opened.

[0052] In the embodiment of the present application, the moving contact 201 can move relative to the stationary contact 202, so that the moving contact 201 can contact the stationary contact 202 to close the switch device 200. Alternatively, the moving contact 201 can also separate from the stationary contact 202 to open the switch device 200.

[0053] Specifically, the operating handle 30 is connected to the moving contact 201, and the operating handle 30 can drive the moving contact 201 to move, so as to realize the movement of the moving contact 201 in the accommodating cavity 11. That is, the opening or closing of the switch device 200 can be controlled by the operating handle 30.

[0054] Since the visual window 12 is opposite to the static contact 202, the user can observe the static contact 202 and the components near the static contact 202 through the visual window 12. In this way, the visual window 12 can provide a window for observation for the static contact 202 and the moving contact 201 when the moving contact 201 moves close to the static contact 202.

[0055] It should be noted that the moving contact 201 may be provided with a moving contact facing the stationary contact 202, and the stationary contact 202 may be provided with a stationary contact facing the moving contact 201. When the moving contact 201 contacts the stationary contact 202, the moving contact and the stationary contact may contact each other.

[0056] That is, the moving contact and the stationary contact can be used as the aforementioned contacts to maintain the normal operation of the switch device 200 .

[0057] The operating mechanism 100 provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0058] Reference Figure 2 , Figure 3 and Figure 4As shown, the present application provides an operating mechanism 100, which is applied to a switch device 200. The operating mechanism 100 includes a housing 10, an isolating member 20, an operating handle 30, and an elastic member 40. The housing 10 has an accommodating cavity 11 inside, and a visible window 12 is provided on the housing 10, and the visible window 12 passes through the cavity wall of the accommodating cavity 11. The isolating member 20 is slidably disposed in the accommodating cavity 11, and can be switched between a first position and a second position.

[0059] In the embodiment of the present application, the operating mechanism 100 includes a housing 10 , an isolating member 20 , an operating handle 30 and an elastic member 40 .

[0060] The housing 10 has a receiving chamber 11 inside, and the isolating member 20 and the elastic member 40 are both disposed in the receiving chamber 11. The operating handle 30 is rotatably connected to the wall of the receiving chamber 11, so that the operating handle 30 can be rotated to drive the moving contact 201 to move, thereby realizing the opening or closing of the switch device 200.

[0061] The visible window 12 is provided on the housing 10 and penetrates the cavity wall of the accommodating cavity 11, so that the visible window 12 can connect the accommodating cavity 11 with the outside of the housing 10. Therefore, the user can observe the situation inside the accommodating cavity 11 through the visible window 12, which is convenient for the user to understand the working situation of the switch device 200.

[0062] During the opening process of the switch device 200, the contacts of the switch device 200 separate, and an arc is formed between the contacts. After the arc is formed, the arc moves in the accommodation cavity 11. During the movement of the arc, it is very likely to spray toward the viewing window 12 and damage the viewing window 12.

[0063] In the embodiment of the present application, an isolating member 20 that can slide in the accommodating cavity 11 is disposed in the accommodating cavity 11 , and the isolating member 20 can be switched between a first position and a second position.

[0064] The operating handle 30 and the elastic member 40 can be used as a driving member to drive the isolation member 20 to switch between the first position and the second position.

[0065] refer to Figure 3 as well as Figure 4 , Figure 3 shows a schematic diagram when the isolation member is in a first position, Figure 4 A schematic diagram showing the isolating element in the second position is shown.

[0066] When the isolating member 20 is located at the first position, the isolating member 20 is misaligned with the visual window 12. Thus, a portion of the space in the accommodating cavity 11 that is opposite to the visual window 12 can be exposed through the visual window 12. At this time, there is no obstruction between the visual window 12 and the interior of the accommodating cavity 11, and the user can observe the situation inside the accommodating cavity 11 through the visual window 12.

[0067] When the partition 20 is in the second position, the partition 20 is opposite to at least a portion of the visible window 12. In this way, the partition 20 can block at least a portion of the visible window 12. At this time, the partition 20 protects the blocked portion of the visible window 12, reducing the possibility of damage to the visible window 12.

[0068] That is, in the present application, the visible window 12 can be protected by the isolation member 20 to reduce the damage of the arc to the visible window 12 , thereby reducing the influence of the arc on the visualization of the switch device 200 .

[0069] In the present application example, the isolating member 20 can be driven by operating the handle 30 or the elastic member 40 so that the isolating member 20 can slide, so that the isolating member 20 can switch between the first position and the second position.

[0070] Specifically, the operating handle 30 is rotatably disposed in the accommodating chamber 11, and is used to control the switch device 200 to close or open. When the operating handle 30 controls the switch device 200 to close, the operating handle 30 drives the isolating member 20 to slide from the second position to the first position. The elastic member 40 is located in the accommodating chamber 11, and the two ends of the elastic member 40 are respectively in contact with the cavity wall of the accommodating chamber 11 and the isolating member 20. When the operating handle 30 controls the switch device 200 to open, the elastic member 40 drives the isolating member 20 to slide from the first position to the second position.

[0071] Through the above arrangement, when the switch device 200 is in the closed state, the isolating member 20 is in the first position, the isolating member 20 is misaligned with the visible window 12, and the user can observe the situation inside the accommodating cavity 11 through the visible window 12. When the switch device 200 is in the open state, the isolating member 20 is in the second position, and the isolating member 20 can block the visible window 12 to protect the visible window 12.

[0072] In this way, when the operating mechanism 100 controls the switch device 200 to switch from closing to opening, the isolating member 20 can slide to the second position to block at least part of the visible window 12. Thus, the isolating member 20 can isolate at least part of the arc generated by the opening, reducing the possibility of the arc damaging the visible window 12 or even causing a safety accident.

[0073] In summary, in the operating mechanism 100 proposed in the present application, when the switch device 200 is in the closed state, the user can normally observe the status of the switch device 200 through the visual window 12 .

[0074] When the operating mechanism 100 controls the switch device 200 to open, the elastic member 40 can push the isolation member 20 to slide to the second position, and the isolation member 20 can protect the visible window 12 to reduce the impact of the arc on the visible window 12.

[0075] In the embodiment of the present application, when the switch device 200 switches from the closed state to the open state, an arc is generated and gradually spreads. At this time, the elastic member 40 can drive the isolation member 20 to slide and gradually block the visible window 12. When the arc spreads to the visible window 12, the arc will be blocked at the isolation member 20, reducing the possibility of further spreading to the visible window 12.

[0076] That is, when the switch is opened, the isolating member 20 can gradually cover the visible window 12 until the next time the switch is closed, when the isolating member 20 will expose the visible window 12 .

[0077] In this way, during the period from arc formation to arc complete extinction, the isolator 20 can keep shielding the visual window 12 to block the arc. Thus, the damage of the arc to the visual window 12 can be reduced, and the influence of the arc on the visualization of the switch device 200 and the possibility of causing safety accidents can be reduced.

[0078] like Figure 4 As shown, the operating mechanism 100 has a first direction X. In the embodiment of the present application, one end of the elastic member 40 away from the isolation member 20 can abut against a cavity wall of the accommodating cavity 11 in the first direction X.

[0079] When the isolation member 20 is located at the second position, one end of the isolation member 20 away from the elastic member 40 may abut against another cavity wall of the accommodating cavity 11 in the first direction X.

[0080] In order to enable the elastic member 40 to support the isolation member 20 and reduce the possibility of the isolation member 20 falling, the elastic member 40 may be in a compressed state when the isolation member 20 is in the second position.

[0081] When the isolation member 20 slides from the second position to the first position, the sliding of the isolation member 20 can further compress the elastic member 40, so that the elastic member 40 can store elastic potential energy.

[0082] When the operating handle 30 rotates to drive the switch device 200 to open, the operating handle 30 rotates and cancels the push against the isolation member 20. During this process, the elastic member 40 can gradually release the elastic potential energy to drive the isolation member 20 to slide. When the operating handle 30 is separated from the isolation member 20, the operating handle 30 cancels the compression of the elastic member 40, and the elastic member 40 can make the isolation member 20 slide to the first position.

[0083] It should be noted that when the isolating member 20 slides to the first position, the isolating member 20 may only be opposite to a portion of the visible window 12. In this way, the isolating member 20 can protect the portion of the visible window 12 opposite to it, reducing the possibility of the arc damaging this portion of the visible window 12, or even damaging the operating mechanism 100 and causing a safety accident.

[0084] Alternatively, the isolating member 20 may have a portion that is opposite to the entire visible window 12, and in this case, the isolating member 20 may also completely block the visible window 12. In this way, the isolating member 20 may protect the entire visible window 12, reducing the possibility of the electric arc damaging the visible window 12, or even damaging the operating mechanism 100 and causing a safety accident.

[0085] It should also be noted that, when the operating mechanism 100 is applied to a switch device 200 , and the switch device 200 is provided with a moving contact 201 and a stationary contact 202 , the visible window 12 is opposite to the stationary contact 202 .

[0086] When the moving contact 201 is separated from the stationary contact 202, an arc is generated between the moving contact 201 and the stationary contact 202. Since the visible window 12 is opposite to the stationary contact 202, when the isolating member 20 is in the first position, the user can observe the stationary contact 202 through the visible window 12, and can intuitively observe that the moving contact 201 is not in contact with the stationary contact 202.

[0087] When the visible window 12 is opposite to the static contact 202 and the switch device 200 switches from the closed state to the open state, the arc between the moving contact 201 and the static contact 202 is close to the visible window 12 and the visible window 12 is easily damaged.

[0088] The isolating member 20 provided in the operating mechanism 100 in the present application can protect the visible window 12 and reduce the influence of the arc on the visualization of the switch device 200 .

[0089] In addition, the elastic member 40 may be a spring, a spring sheet or other components made of elastic materials. The specific type of the elastic member 40 is not specifically limited in the embodiment of the present application.

[0090] The elastic member 40 drives the isolation member 20 to slide by its own elastic potential energy, and can also improve the response speed of the isolation member 20 when sliding from the second position to the first position, so as to better protect the visible window 12.

[0091] In addition, in order to increase the service life of the isolation member 20 and improve the protection effect on the visual window 12, the isolation member 20 can be made of a material resistant to arc ablation, such as tungsten copper alloy or copper chromium alloy.

[0092] In some embodiments, Figure 2 and Figure 3 As shown, a cover plate 18 may be provided on the housing 10 , the cover plate 18 covers the viewing window 12 , and the cover plate 18 is a transparent structure.

[0093] Through the above arrangement, the cover 18 is covered on the visible window 12, and the cover 18 can close the position where the visible window 12 is opened on the shell 10, thereby reducing the possibility that external dust and the like enter the accommodating chamber 11 through the visible window 12 and affect the operation of the components in the accommodating chamber 11.

[0094] Furthermore, since the cover plate 18 is a transparent structure, the possibility that the cover plate 18 blocks the visual window 12 and affects the visualization of the switch device 200 can be reduced. That is, when the user needs to observe the working condition of the switch device 200 through the visual window 12, the user can observe through the cover plate 18.

[0095] When a cover plate 18 is disposed on the visual window 12, the arc is likely to spray toward the cover plate 18 after being generated, thereby burning the cover plate 18 or blackening the cover plate 18, making the cover plate 18 less transparent or opaque. In this way, the cover plate 18 affects the visualization of the switch device 200, thereby reducing the viewing experience of the user.

[0096] In the present application, due to the provision of the isolation member 20 , the isolation member 20 can isolate the electric arc sprayed toward the cover plate 18 , thereby reducing the possibility of the electric arc directly acting on the cover plate 18 , thereby burning or blackening the cover plate 18 .

[0097] Of course, the cover plate 18 may not be provided on the viewing window 12, so that the user can directly observe the working state of the switch device 200 through the viewing window 12. At this time, if an arc sprays toward the viewing window 12, it is easy to damage the housing 10 near the viewing window 12, or even spray directly from the viewing window 12, threatening the safety of the user.

[0098] In this case, the setting of the isolation member 20 can block the arc, reduce the possibility of the arc ejecting from the visual window 12, and improve the safety of the switch device 200.

[0099] In some embodiments, Figure 4 and Figure 5 As shown, the isolating member 20 can slide along the first direction X. The isolating member 20 may include a sliding portion 21, a connecting portion 22, and a baffle 23. In the first direction X, the connecting portion 22 has a first end 221 and a second end 222 opposite to each other, the first end 221 is away from the visual window 12, the sliding portion 21 is connected to the first end 221, and the baffle 23 is connected to the second end 222. When the isolating member 20 is in the second position, the baffle 23 is opposite to at least a portion of the visual window 12.

[0100] In the embodiment of the present application, the isolating member 20 slides in the accommodating cavity 11 along the first direction X. When the isolating member 20 slides along the first direction X, the relative position relationship between the isolating member 20 and the visible window 12 can be changed, so that the isolating member 20 can cover the visible window 12 or be misaligned with the visible window 12.

[0101] The isolating member 20 includes a sliding portion 21 , a connecting portion 22 and a baffle 23 , and the sliding portion 21 and the baffle 23 are both connected to the connecting portion 22 .

[0102] Specifically, the connecting portion 22 has a first end 221 and a second end 222 that are opposite to each other along the first direction X. The sliding portion 21 may be connected to the first end 221 , and the baffle 23 may be connected to the second end 222 .

[0103] Since the first end 221 is far from the visual window 12, in the isolation member 20, the sliding portion 21 is located at a side far from the visual window 12, and the baffle 23 is located at a side close to the visual window 12. In this way, when the isolation member 20 slides from the first position to the second position, the baffle 23 can slide to a position opposite to the visual window 12 first.

[0104] Based on this, when the isolating member 20 is in the second position, the baffle 23 can be used to protect the visible window 12, thereby reducing the sliding stroke of the isolating member 20 when it plays a protective role. In this way, the space of the accommodating cavity 11 occupied by the isolating member 20 to meet the sliding stroke can be reduced, thereby reducing the impact of the setting of the isolating member 20 on other components in the accommodating cavity 11 and reducing the possibility of increasing the size of the accommodating cavity 11.

[0105] like Figure 3 and Figure 4 As shown, a driving rod 301 is connected to the operating handle 30 , and the operating handle 30 can drive the isolation member 20 through the driving rod 301 .

[0106] The driving rod 301 may be located between the sliding portion 21 and the baffle 23. When the operating handle 30 controls the switch device 200 to close, the driving rod 301 may push the sliding portion 21 to slide the isolating member 20 from the second position to the first position.

[0107] With operating mechanism 100 press Figure 4 Taking the orientation shown as an example, in the state shown in the figure, the first direction X is consistent with the left-right direction.

[0108] Recombination Figure 2 The stationary contact 202 and the visible window 12 are located on the right side of the accommodating cavity 11 , the moving contact 201 is arranged on the left side of the stationary contact 202 , and the operating handle 30 is located on the left side of the visible window 12 .

[0109] When the switch device 200 is in the open state, the operating handle 30 can be rotated clockwise to push the moving contact 201 to the right, so that the moving contact 201 moves to the side close to the static contact 202, thereby closing the switch device 200. When the switch device 200 is in the closed state, the operating handle 30 can be rotated counterclockwise to pull the moving contact 201 to the left, so that the moving contact 201 moves to the side away from the static contact 202, thereby opening the switch device 200.

[0110] When the operating handle 30 controls the switch device 200 to switch from the open state to the closed state, the operating handle 30 can rotate clockwise and drive the driving rod 301 to rotate synchronously with the operating handle 30 .

[0111] During this process, the driving rod 301 first rotates between the sliding part 21 and the baffle 23, and then can abut against the sliding part 21. As the driving rod 301 continues to rotate, the driving rod 301 can push the sliding part 21, so that the sliding part 21 can slide to the left. During the sliding of the sliding part 21, the sliding part 21 can drive the baffle 23 to slide through the connecting part 22, so that the baffle 23 and the visual window 12 are misaligned.

[0112] In some embodiments, Figure 6 and Figure 7 As shown, the housing 10 may also be provided with an operating hole 13 spaced apart from the visual window 12, and the operating hole 13 penetrates the cavity wall of the accommodating cavity 11. The operating handle 30 includes an operating rod 31 and a connecting member 32, the connecting member 32 is rotatably connected to the cavity wall of the accommodating cavity 11, the operating rod 31 is connected to the connecting member 32, and at least part of the operating rod 31 extends out of the housing 10 through the operating hole 13, and the operating rod 31 is used to drive the connecting member 32 to rotate so that the connecting member 32 controls the switch device 200 to close or open. The driving rod 301 is connected to the side of the connecting member 32 away from the operating hole 13.

[0113] Since the operation hole 13 passes through the cavity wall of the accommodating cavity 11 , the operation hole 13 communicates with the accommodating cavity 11 and the outside of the operating mechanism 100 .

[0114] Based on this, after the operating handle 30 is installed on the housing 10 , part of the operating handle 30 may be located in the accommodating cavity 11 , and part of the operating handle 30 may extend through the operating hole 13 .

[0115] Specifically, the operating handle 30 includes an operating rod 31 and a connecting member 32. The connecting member 32 can be connected to the cavity wall of the accommodating cavity 11 and is located in the accommodating cavity 11. The operating rod 31 can be connected to the position of the connecting member 32 facing the operating hole 13 so that the operating rod 31 can extend through the operating hole 13.

[0116] In this way, the operating rod 31 can be used as a user's operating part, and the connecting member 32 can be connected to the moving contact 201. Therefore, when the user controls the operating rod 31 to rotate, the connecting member 32 can rotate and control the moving contact 201 to move, so that the moving contact 201 contacts or separates from the static contact 202.

[0117] The driving rod 301 can be specifically connected to the side of the connecting member 32 away from the operating hole 13, so that the driving rod 301 can push the sliding part 21 when rotating, so as to realize the sliding of the isolation member 20 from the second position to the first position.

[0118] It should be noted that, in order to reduce the number of parts of the operating mechanism 100 and reduce the manufacturing difficulty, the operating handle 30 and the driving rod 301 can be integrally formed. In this way, the connecting member 32, the operating rod 31 and the driving rod 301 can be formed in one processing process, and the operating handle 30 and the driving rod 301 can be installed as a whole as a structural member during installation.

[0119] Of course, the operating handle 30 and the driving rod 301 can also be connected in other ways. For example, the driving rod 301 can be connected to the operating handle 30 by welding, bonding or screwing. The specific connection method of the operating handle 30 and the driving rod 301 is not specifically limited in the embodiment of the present application.

[0120] In some embodiments, Figures 2 to 4 As shown, when the switch device 200 is in the closed state, the operating handle 30 abuts against part of the isolating member 20. In the process of rotating the operating handle 30 to control the switch device 200 to switch to the open state, the abutting portion of the operating handle 30 and the isolating member 20 gradually decreases. When the operating handle 30 rotates to a first angle, the operating handle 30 separates from the isolating member 20. When the operating handle 30 rotates to a second angle, the switch device 200 completes the state switching. The first angle is smaller than the second angle.

[0121] That is, in the embodiment of the present application, when the switch device 200 is in the closed state, the operating handle 30 abuts against a portion of the isolating member 20. When the switch device 200 is in the open state, the operating handle 30 is separated from the isolating member 20.

[0122] In this way, during the process of the operating handle 30 controlling the switch device 200 to switch from the closed state to the open state, the abutment area between the operating handle 30 and the isolation member 20 will gradually decrease. At the same time, the elastic member 40 can gradually release elastic potential energy under the action of its own elastic force to push the isolation member 20 to slide to the first position.

[0123] Furthermore, by setting the first angle smaller than the second angle, the operating handle 30 can be separated from the isolation member 20 earlier.

[0124] In this way, when the operating handle 30 controls the switch device 200 to switch from the closed state to the open state, the operating handle 30 can first be rotated to a first angle to separate it from the isolation member 20, and then rotated to a second angle so that the switch device 200 completes the opening action.

[0125] In this way, the operating handle 30 can first cancel the force on the isolation member 20, so that the elastic member 40 can stretch and push the isolation member 20 to the first position. At the same time, the operating handle 30 continues to rotate to complete the switching action of the switch device 200 state.

[0126] Based on this, when the operating handle 30 is rotated and the opening switch has not yet been completed, the isolation member 20 can slide to the first position under the action of the elastic member 40 to protect the viewing window 12.

[0127] That is, in the embodiment of the present application, the protection of the visible window 12 by the isolation member 20 can be completed during the process of switching the switch device 200 from the closed state to the open state, and before the completion of the open state.

[0128] In this way, the response speed of the isolating element 20 can be improved, so that the isolating element 20 can cover the visible window 12 at the initial stage of switching the switch device 200 from the closed state to the open state, thereby improving the isolation and blocking effect of the arc.

[0129] In other words, the arrangement of the present application can reduce the possibility that the isolation member 20 slides late, resulting in the isolation member 20 sliding to the first position to block the visible window 12 when the arc has already been generated or even spread to the visible window 12. The isolation member 20 can further improve the protective effect of the visible window 12.

[0130] It should be noted that the present application achieves an earlier separation of the operating handle 30 from the isolation member 20 through the constraint relationship between the first angle and the second angle.

[0131] In order to realize the above configuration, the contact portion between the operating handle 30 and the isolating member 20 can be reduced in the closed state, such as Figure 2 and Figure 3 In this way, the operating handle 30 can be separated from the isolation member 20 earlier.

[0132] In the embodiment of the present application, the first angle and the second angle can be set specifically according to the type of the switch device 200 .

[0133] For example, when the switch device 200 is a circuit breaker, the rotation angle of the operating handle 30 when the circuit breaker is opened is generally between 45° and 90°, such as 45°, 48°, 50°, 53°, etc.

[0134] At this time, the first angle can be between 15° and 25°, such as 15°, 18°, 20°, 22°, and so on.

[0135] For other types of switch devices 200 , the first angle and the second angle may be set specifically according to their own parameters, which will not be described in detail in the embodiments of the present application.

[0136] It should also be noted that, when the operating handle 30 further includes the driving rod 301 and the isolating member 20 includes the sliding portion 21 , the driving rod 301 may be separated from the sliding portion 21 earlier.

[0137] Specifically, the length of the driving rod 301 can be set shorter. In this way, in the closed state, the driving rod 301 has less contact with the sliding part 21, which facilitates the separation of the driving rod 301 and the sliding part 21.

[0138] Here, the first angle is 45° and the second angle is 20°. When the switch device 200 is in the closed state, the operating handle 30 can be rotated to switch the switch device 200 to the open state.

[0139] When the rotation angle is between 0° and 20°, the contact between the driving rod 301 and the sliding portion 21 gradually decreases, and the compression of the elastic member 40 by the driving rod 301 also gradually decreases.

[0140] When the rotation angle is 20°, the driving rod 301 is separated from the sliding portion 21, and the driving rod 301 cancels the push against the isolation member 20 and the compression of the elastic member 40. The elastic member 40 can push the isolation member 20 to slide to the first position under its own elastic force.

[0141] As the operating handle 30 continues to rotate, when the rotation angle reaches 45°, the switch device 200 completes the switching and is in the open state.

[0142] Of course, if Figure 4 As shown, the driving rod 301 can also be set longer. In this case, when the switch device 200 switches from the closed state to the open state, the driving rod 301 is separated from the isolating member 20 later. Specifically, it can be set according to the performance of the switch device 200, the first angle, the second angle and other parameters.

[0143] In some embodiments, Figure 5 and Figure 6 As shown, a guide groove 14 extending along the first direction X may be provided on the cavity wall of the accommodating cavity 11 , and the sliding portion 21 is embedded in the guide groove 14 and can slide in the guide groove 14 .

[0144] Through the above arrangement, the sliding portion 21 can be slidably arranged in the guide groove 14. On one hand, the guide groove 14 cooperates with the sliding portion 21 to achieve the installation of the isolation member 20 in the accommodating cavity 11.

[0145] On the other hand, when the isolating member 20 slides, the guide groove 14 guides the sliding of the sliding portion 21, thereby reducing the possibility of the isolating member 20 being offset during the sliding process.

[0146] In this way, it can be further ensured that the isolation member 20 can slide to the position where the baffle 23 can cover the visible window 12, thereby reducing the possibility that the baffle 23 loses its protective effect on the visible window 12.

[0147] In some embodiments, Figures 4 to 6 As shown, the first guide plate 15 and the second guide plate 16 can be connected to the cavity wall of the accommodating cavity 11, the first guide plate 15 and the second guide plate 16 are spaced apart, and both the first guide plate 15 and the second guide plate 16 extend along the first direction X. The surface of the first guide plate 15 facing the second guide plate 16 and the surface of the second guide plate 16 facing the first guide plate 15 form the groove wall of the guide groove 14, and the sliding portion 21 is embedded between the first guide plate 15 and the second guide plate 16.

[0148] Through the above arrangement, the first guide plate 15 and the second guide plate 16 can cooperate with each other to install and guide the sliding part 21 .

[0149] The first guide plate 15 and the second guide plate 16 are spaced apart from each other, so that the gap between the first guide plate 15 and the second guide plate 16 can provide an installation space for the sliding part 21 .

[0150] That is, the sliding portion 21 can be disposed in the gap between the first guide plate 15 and the second guide plate 16 , so that the surface of the first guide plate 15 facing the second guide plate 16 and the surface of the second guide plate 16 facing the first guide plate 15 can form the groove wall of the guide groove 14 .

[0151] Since the first guide plate 15 and the second guide plate 16 both extend along the first direction X, the gap between the first guide plate 15 and the second guide plate 16 also extends along the first direction X. In this way, a sliding space can be provided for the sliding portion 21, and the possibility that the arrangement of the first guide plate 15 and the second guide plate 16 affects the sliding of the sliding portion 21 is reduced.

[0152] In this way, during the sliding process of the isolation member 20 , the sliding portion 21 can slide along the surface of the first guide plate 15 toward the second guide plate 16 , and along the surface of the second guide plate 16 toward the first guide plate 15 .

[0153] It should be noted that if Figure 6 As shown, a limit plate 17 can also be provided on the cavity wall of the accommodating cavity 11, and the limit plate 17 is located on the side of the first guide plate 15 away from the visual window 12, and is connected to both the first guide plate 15 and the second guide plate 16. In this way, the limit plate 17 can close the guide groove 14.

[0154] At this time, one end of the elastic member 40 away from the isolation member 20 may abut against the limiting plate 17 .

[0155] When the isolating member 20 slides from the first position to the second position, the sliding member will squeeze the elastic member 40, so that the elastic member 40 is compressed. The setting of the limiting plate 17 can limit the sliding of the isolating member 20, reducing the possibility that the sliding portion 21 over-compresses the elastic member 40 due to excessive sliding of the limiting plate 17, thereby reducing the possibility of damaging the elastic member 40.

[0156] It should also be noted that, in addition to providing the first guide plate 15 and the second guide plate 16 to form the guide groove 14 , the guide groove 14 may also be formed by other methods.

[0157] For example, part of the material on the cavity wall of the accommodating cavity 11 may be directly removed to form the inwardly recessed guide groove 14 .

[0158] At this time, the connecting portion 22 and the sliding portion 21 may both be disposed in the guide groove 14 .

[0159] In some embodiments, the isolating element 20 can play an indicating role. The isolating element 20 can be arranged in different ways, and the following two ways are specifically used as examples for explanation.

[0160] In the first embodiment, the spacer 20 is a non-transparent structure.

[0161] Thus, the separator 20 has a color, and when the separator 20 slides to the second position, the part of the separator 20 opposite to the visual window 12 can be observed by the user.

[0162] With the above arrangement, when the baffle 23 shields the visual window 12 to protect the visual window 12, the user can observe the colored separator 20 through the visual window 12. The separator 20 can indicate the state of the switching device 200.

[0163] That is, when the user observes through the visual window 12 and observes the colored separator 20, it can be determined based on the observed situation that the switching device 200 is in the open state.

[0164] It should be noted that a coating such as a colored pigment can be sprayed on the separator 20 to form a non-transparent separator 20, or the separator 20 can also be made of a material that inherently has a color that is easy to observe.

[0165] In the second method, an indicating structure is provided on the separator 20. When the separator 20 is in the second position, at least part of the indicating structure is opposite to the visual window 12, and the indicating structure is used to indicate that the switching device 200 is in the open state.

[0166] With the above arrangement, when the baffle 23 shields the visual window 12 to protect the visual window 12, the user can observe the indicating structure through the visual window 12. Thus, the separator 20 can indicate the state of the switching device 200.

[0167] That is, when the user observes through the visual window 12 and observes the indicating structure, it can be determined based on the observed situation that the switching device 200 is in the open state.

[0168] It should be noted that the indicating structure can have different arrangements. For example, a pattern with an indicating function, such as "open" or "×", can be etched on the separator 20.

[0169] In this embodiment, the separator 20 as a whole can be a transparent structure, and the indicating structure can have a color.

[0170] In this application example, the visual window 12 itself can also make the static contact 202 and the components near the static contact 202 visible, and thus can indicate the state of the switching device 200.

[0171] Thus, the switching device 200 equipped with the above operating mechanism 100 has a dual-indicating function. That is, the state of the switching device 200 can be indicated through the visual window 12 and the separator 20.

[0172] When the isolating member 20 blocks the visible window 12, the user can judge the state of the switch device 200 through the isolating member 20. This can reduce the possibility of misjudging the state of the switch device 200 when the isolating member 20 blocks the visible window 12 and the user cannot directly observe the states of the moving contact 201 and the stationary contact 202 through the visible window 12.

[0173] In addition, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the housing 10 may include a base 101 and an upper cover 102 , and the base 101 and the upper cover 102 may be buckled together to form a receiving cavity 11 .

[0174] In this way, it is convenient to arrange the operating handle 30 , the isolation member 20 and the like in the accommodating cavity 11 .

[0175] When the housing 10 is provided with a base 101 and an upper cover 102 , the visible window 12 may be opened on the base 101 and / or the upper cover 102 .

[0176] Specifically, the visible window 12 can be arranged on the side of the base 101 facing the upper cover 102, and on the side of the upper cover 102 facing the base 101. The part of the visible window 12 located on the side of the base 101 facing the upper cover 102 is opposite to the part of the visible window 12 located on the side of the upper cover 102 facing the base 101, and the two parts can be connected to form the visible window 12.

[0177] Of course, the visible window 12 may also be provided only on the base 101 , or the visible window 12 may also be provided only on the upper cover 102 .

[0178] In addition, similar to the viewing window 12 , the operating hole 13 may also be provided on the base 101 and / or the upper cover 102 .

[0179] In the embodiment of the present application, when the switch device 200 is opened, resulting in an arc in the accommodating chamber 11, the elastic member 40 can push the isolating member 20, so that the isolating member 20 slides to the second position. In this way, the isolating member 20 can protect the visual window 12, reduce the damage of the arc to the visual window 12, and further reduce the influence of the arc on the visualization of the switch device 200 and the possibility of causing a safety accident.

[0180] Finally, it should be noted that the above embodiments are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
