Description

Technical Field

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

[0002] A circuit breaker's manual override is a device that allows the operator to manually control the opening and closing of the circuit breaker. Manual overrides are typically used in situations where operation via an automated control system is impossible or inconvenient, or as a backup mode of operation during maintenance and testing.

[0003] Manual operating mechanisms typically include a knob and an indicator dial. Operators manually control the opening and closing of a circuit breaker by turning the knob. The indicator dial typically features status indicators, and the knob points to corresponding status indicators depending on the circuit breaker's status. However, existing technologies have the problem of the knob not being able to point to the corresponding status indicator. Utility Model Content

[0004] The present application provides a hand-operated mechanism and an electrical switch, which improve the accuracy of knob indication.

[0005] In a first aspect, the present application provides a manual operating mechanism for use with a circuit breaker. The manual operating mechanism comprises a bracket, an indicator dial, and a knob. The bracket is fixedly connected to the circuit breaker. The indicator dial is disposed on a side of the bracket away from the circuit breaker, and the relative position of the indicator dial and the bracket remains fixed. The knob includes a drive unit that extends through the indicator dial to rotate the knob and connect it to the indicator dial.

[0006] According to the above scheme, by setting a knob, the circuit breaker can be controlled to switch its state. The driving part passes through the indicator disk, so that the knob can be installed on the indicator disk. The knob is rotatably connected to the indicator disk. When the knob is rotated, the direction of the knob will change. In this way, the knob can be used to indicate different status marks on the indicator disk. The setting of the bracket can play a supporting role for the installation of the indicator disk. The relative position of the indicator disk and the bracket is fixed, and the bracket can be used to limit the indicator disk. When the indicator disk is limited, the probability of the indicator disk rotating with the knob during the rotation of the knob can be reduced. In this way, the indication efficiency of the knob can be improved, and the probability of the electrical switch having a problem of inconsistency between the current actual state and the displayed state can be reduced.

[0007] In one possible design, the manual operating mechanism further includes a first fastener. A first fixing hole is defined on a side of the bracket facing away from the circuit breaker, and a second fixing hole is defined on the indicator plate, the second fixing hole being positioned opposite the first fixing hole. The first fastener passes through the first and second fixing holes, securing the bracket and the indicator plate together.

[0008] With the above solution, a first fixing hole is provided on the bracket, and a second fixing hole is provided on the indicator disc. The indicator disc can be fixed to the bracket using a first fastener. Once the indicator disc is fixed to the bracket, the relative position between the indicator disc and the bracket remains fixed during use of the electrical switch. The first fixing hole and the second fixing hole are positioned opposite each other, facilitating installation and removal of the first fastener and reducing the likelihood of problems such as difficulty or inability to install the first fastener due to misalignment between the first fixing hole and the second fixing hole.

[0009] In a possible design, a clamping block is provided on a side of the bracket facing the indicator disk, and a clamping slot is provided on a side of the indicator disk facing the bracket. The clamping block and the clamping slot are clamped to each other.

[0010] With the above solution, a clamping block is provided on the bracket, and a clamping slot is provided on the indicator disc. The clamping block and the clamping slot engage to secure the indicator disc to the bracket. Once the indicator disc is secured to the bracket, the relative position of the indicator disc and the bracket remains fixed during use of the electrical switch. Furthermore, the clamping engagement between the bracket and the indicator disc facilitates disassembly. If the bracket or the indicator disc becomes damaged or deteriorates during use, the damaged or deteriorated parts can be easily replaced, reducing the difficulty of subsequent maintenance of the electrical switch.

[0011] In a possible design, at least two spaced-apart limit blocks are provided on a side of the bracket facing the indicator plate, the indicator plate is located between the at least two limit blocks, and the side wall of the indicator plate abuts against the at least two limit blocks at the same time.

[0012] With the above solution, at least two spaced-apart stoppers are provided on the bracket. When the indicator disc is mounted on the bracket, the sidewalls of the indicator disc simultaneously abut against the at least two spaced-apart stoppers. This allows the spaced-apart stoppers to clamp the indicator disc, thereby securing the indicator disc to the bracket. Once the indicator disc is secured to the bracket, the relative position between the indicator disc and the bracket remains fixed during use of the electrical switch. Furthermore, by using the spaced-apart stoppers to clamp the indicator disc, the step of providing a connecting structure on the indicator disc is eliminated, thereby reducing the manufacturing difficulty and cost of the electrical switch.

[0013] In one possible design, the indicator plate is provided with a first mounting hole, the bracket is provided with a second mounting hole, the first mounting hole and the second mounting hole are of the same size and are positioned opposite each other, and the driving unit passes through both the first mounting hole and the second mounting hole.

[0014] Through the above solution, the provision of the first and second mounting holes can provide installation space for the driver unit. The first and second mounting holes are of the same size and are positioned opposite each other. This can reduce the probability of difficulty or difficulty in installing the driver unit due to misalignment between the first and second mounting holes when the driver unit passes through the first and second mounting holes.

[0015] In one possible design, the bracket includes a first support plate, a connecting plate, and a second support plate connected in sequence, wherein the first support plate and the second support plate are arranged in parallel, the indicator plate is arranged on the first support plate, and the second support plate is fixedly connected to the circuit breaker.

[0016] With this solution, the first and second support plates are arranged parallel to each other and connected by a connecting plate. This creates a gap between the first and second support plates, facilitating installation of the drive unit through the bracket. The indicator plate is mounted on the first support plate, and the second support plate is fixedly connected to the circuit breaker. This allows the different functions of the bracket to be arranged in separate blocks, facilitating installation of the electrical switch and reducing the risk of incorrect or missing switches due to integrating different functions into the same area of ​​the bracket.

[0017] In a possible design, the manual operating mechanism further includes a manual operating base and a second fastener, wherein the manual operating base is disposed between the circuit breaker and the bracket, and the manual operating base and the bracket are fixedly connected via the second fastener.

[0018] With this solution, the manual control base not only provides installation space for the remaining components of the manual control mechanism, but also protects them. Furthermore, the provision of the manual control base can share some of the functions of the bracket, thereby simplifying the bracket's functionality. This reduces the cost of repairing or replacing the bracket when it ages or becomes damaged, thereby lowering the cost of using the manual control mechanism.

[0019] In one possible design, the second support plate is provided with a third fixing hole, and the hand-operated base is provided with a fourth fixing hole, the fourth fixing hole being positioned opposite the third fixing hole. A second fastener passes through the fourth fixing hole and connects with the third fixing hole, thereby securing the hand-operated base to the bracket via the second fastener.

[0020] With the above solution, a third fixing hole is provided on the second support plate, and a fourth fixing hole is provided on the hand-operated base. The bracket can be fixedly connected to the hand-operated base using a second fastener. The third fixing hole and the fourth fixing hole are positioned opposite each other, facilitating installation and removal of the second fastener, thereby reducing the likelihood of problems such as difficulty or inability to install the second fastener due to misalignment between the third and fourth fixing holes. When securing the bracket to the hand-operated base, the second fastener passes through the fourth and third fixing holes in sequence. This reduces the likelihood that, after installation, the portion of the second fastener not connected to the third and fourth fixing holes will interfere with components within the hand-operated base, thereby improving the reliability of the hand-operated mechanism.

[0021] In one possible design, the manual operating mechanism further includes an operating lever. The operating lever includes a first end and a second end positioned opposite each other. The first end passes through the manual operating base and is connected to the circuit breaker, and the second end is fixedly connected to an end of the driving portion away from the knob.

[0022] Through the above solution, the operating lever connects the knob to the circuit breaker, allowing the manual operating mechanism to control the internal state of the circuit breaker. Furthermore, the operating lever is relatively inexpensive to manufacture, and if the operating lever becomes aged or damaged, the cost of repairing or replacing it is much lower, thus reducing the cost of using the manual operating mechanism.

[0023] In a second aspect, the present application provides an electrical switch, comprising a circuit breaker and the manual operating mechanism mentioned in the first aspect. The circuit breaker is connected to the manual operating mechanism.

[0024] The beneficial effects of the electrical switch provided in the second aspect can be referred to the beneficial effects brought about by the first aspect and the various possible implementation methods of the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] Figure 1 This is a schematic diagram of the overall structure of the electrical switch provided in an embodiment of the present application. Figure 2 This is an exploded view of the hand-operated mechanism provided in the embodiment of the present application. Figure 1 as well as Figure 2 As shown, the present application provides an electrical switch, which includes a circuit breaker 600 and a manual operating mechanism. The circuit breaker 600 is connected to the manual operating mechanism.

[0050] An electrical switch is an electronic component in a power system that is used to open a circuit, interrupt current flow, or redirect current flow. Electrical switches can be controlled automatically by the system or manually by an operator.

[0051] Circuit breaker 600 is a component of an electrical switch. It can quickly disconnect a circuit in the event of an overload, short circuit, or other abnormality, protecting electrical equipment and circuits. Circuit breaker 600 offers high reliability, high breaking capacity, versatility, and energy-saving and environmentally friendly features.

[0052] The manual operating mechanism can be connected to the circuit breaker 600. By manually controlling the manual operating mechanism, the circuit breaker 600 can be controlled to change its state, thereby controlling the current state.

[0053] The hand-operated mechanism provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0054] Figure 3 This is a partial structural diagram of the hand-operated mechanism provided in the embodiment of the present application. Figures 1 to 3 As shown, the present application provides a manual operating mechanism for use with a circuit breaker 600. The manual operating mechanism includes a bracket 100, an indicator plate 200, and a knob 300. The bracket 100 is fixedly connected to the circuit breaker 600. The indicator plate 200 is disposed on a side of the bracket 100 away from the circuit breaker 600. The relative positions of the indicator plate 200 and the bracket 100 are fixed. The knob 300 includes a driving portion 310 that passes through the indicator plate 200 to rotate the knob 300 and connect it to the indicator plate 200.

[0055] The bracket 100 may be disposed outside the circuit breaker 600. The bracket 100 may be connected to the circuit breaker 600 via a connector. For example, the bracket 100 may be fixed to the circuit breaker 600 via bolts. Alternatively, the bracket 100 may be welded to the circuit breaker 600.

[0056] The indicator disc 200 is mounted on the bracket 100, and the bracket 100 is positioned between the indicator disc 200 and the circuit breaker 600. The indicator disc 200 may be circular or square. The indicator disc 200 is fixedly connected to the bracket 100, and the bracket 100 is fixedly connected to the circuit breaker 600. This allows the relative positions of the indicator disc 200 and the bracket 100 to remain unchanged, and the relative positions of the indicator disc 200 and the circuit breaker 600 can also remain unchanged.

[0057] The knob 300 includes a rotating portion and a drive portion 310, which are interconnected. The drive portion 310 extends through the indicator disc 200 and connects to the handle of the circuit breaker 600. The rotating portion is located on the side of the indicator disc 200 facing away from the bracket 100. The knob 300 also includes a pointing structure, which can be an arrow or other marking on the rotating portion, or the rotating portion itself can serve as the pointing structure. The side of the indicator disc 200 facing away from the bracket 100 can be provided with multiple different status indicators. Twisting the rotating portion causes the pointing structure to indicate the different status indicators.

[0058] The present application provides a manual operating mechanism for a circuit breaker 600, which can manually control the state transitions of the circuit breaker 600. When the knob 300 is turned, the driver 310 can drive the handle of the circuit breaker 600 to actuate. At this point, the state of the circuit breaker 600 changes, and the directional structure on the knob 300 can indicate the relevant state on the indicator disk 200.

[0059] For example, when the knob 300 is turned, the driver 310 drives the handle to disconnect the circuit in the circuit breaker 600. In this case, the pointing structure may point to the status indicator on the indicator plate 200 indicating that the circuit is disconnected. Alternatively, when the knob 300 is turned, the driver 310 drives the handle to connect the circuit in the circuit breaker 600. In this case, the pointing structure may point to the status indicator on the indicator plate 200 indicating that the circuit is connected.

[0060] In summary, by providing the knob 300, the circuit breaker 600 can be controlled to switch between different states. The drive unit 310 passes through the indicator disc 200, allowing the knob 300 to be mounted on the indicator disc 200. The knob 300 is rotatably connected to the indicator disc 200. As the knob 300 is rotated, the direction of the knob 300 changes, allowing the knob 300 to indicate different state indicators on the indicator disc 200. The bracket 100 provides support for the installation of the indicator disc 200. The relative position of the indicator disc 200 and the bracket 100 remains fixed, allowing the bracket 100 to limit the position of the indicator disc 200. When the indicator disc 200 is limited, the probability of the indicator disc 200 rotating with the knob 300 during rotation is reduced. This improves the indication efficiency of the knob 300 and reduces the probability of the actual state of the electrical switch being inconsistent with the displayed state.

[0061] The connection between the indicator plate 200 and the bracket 100 will be described in detail below with reference to the accompanying drawings.

[0062] Figure 4 A schematic structural diagram of the bracket provided in an embodiment of the present application. Figure 5 A schematic diagram of the structure of the indicator disk provided in an embodiment of the present application.

[0063] like Figure 1 、 Figure 4 as well as Figure 5 As shown, the manual operating mechanism also includes a first fastener. A first fixing hole 110 is defined on the side of the bracket 100 away from the circuit breaker 600. A second fixing hole 210 is defined on the indicator plate 200, with the second fixing hole 210 positioned opposite the first fixing hole 110. The first fastener passes through the first fixing hole 110 and the second fixing hole 210, securing the bracket 100 and the indicator plate 200 together.

[0064] The first fastener is used to fix the indicator plate 200 on the bracket 100 so that the relative position of the indicator plate 200 and the bracket 100 can be fixed. The first fastener can be a bolt.

[0065] The first fixing hole 110 may be a plain hole, and the second fixing hole 210 may be a threaded hole, and a bolt may pass through the first fixing hole 110 and be fixed in the second fixing hole 210. Alternatively, the first fixing hole 110 may be a threaded hole, and the second fixing hole 210 may be a plain hole, and a bolt may pass through the second fixing hole 210 and be fixed in the first fixing hole 110. Alternatively, the first fixing hole 110 may be a plain hole, and the second fixing hole 210 may also be a plain hole, and a bolt may pass through both the first fixing hole 110 and the second fixing hole 210 and be fastened with a nut.

[0066] In summary, by providing the first fixing hole 110 on the bracket 100 and the second fixing hole 210 on the indicator plate 200, the indicator plate 200 can be secured to the bracket 100 using a first fastener. Once the indicator plate 200 is secured to the bracket 100, the relative position between the indicator plate 200 and the bracket 100 remains fixed during use of the electrical switch. The relative position of the first fixing hole 110 and the second fixing hole 210 facilitates installation and removal of the first fastener, reducing the likelihood of problems such as difficulty or inability to install the first fastener due to misalignment between the first fixing hole 110 and the second fixing hole 210.

[0067] Please continue to refer to Figure 1 、 Figure 4 as well as Figure 5 As shown, a clamping block is provided on one side of the bracket 100 facing the indicator plate 200, and a clamping slot is provided on one side of the indicator plate 200 facing the bracket 100. The clamping block and the clamping slot are clamped to each other.

[0068] The card block can be a protruding structure provided on the side of the bracket 100 facing the indicator plate 200 , and the card slot can be a groove structure provided on the side of the indicator plate 200 facing the bracket 100 . The card block can cooperate with the card slot to enable the indicator plate 200 to be connected to the bracket 100 .

[0069] A slot may be further provided on the side of the bracket 100 facing the indicator plate 200 , and a block may be provided on the side of the indicator plate 200 facing the bracket 100 . The block may cooperate with the slot to enable the indicator plate 200 to be snapped onto the bracket 100 .

[0070] In summary, a clamping block is provided on the bracket 100, and a clamping slot is provided on the indicator disc 200. The clamping block and the clamping slot engage to secure the indicator disc 200 to the bracket 100. Once the indicator disc 200 is secured to the bracket 100, the relative position of the indicator disc 200 and the bracket 100 remains fixed during use of the electrical switch. Furthermore, the clamping connection between the bracket 100 and the indicator disc 200 facilitates disassembly of the bracket 100 and the indicator disc 200. If the bracket 100 or the indicator disc 200 becomes damaged or degraded during use, the damaged or degraded parts can be easily replaced, reducing the difficulty of subsequent maintenance of the electrical switch.

[0071] Please continue to refer to Figure 1 、 Figure 4 as well as Figure 5 As shown, at least two spaced-apart limit blocks are provided on one side of the bracket 100 facing the indicator plate 200 , the indicator plate 200 is located between the at least two limit blocks, and the side wall of the indicator plate 200 abuts against the at least two limit blocks at the same time.

[0072] The limit block can be a protruding structure provided on one side of the bracket 100 facing the indicator plate 200. There can be two, three or four limit blocks, etc. The following is an example of only two limit blocks.

[0073] The two stoppers can be positioned opposite each other with a gap between them. The gap between the two stoppers constitutes the installation space within which the indicator disk 200 can be installed. When the indicator disk 200 is installed within the installation space, the sidewalls of the indicator disk 200 simultaneously abut against the two stoppers, thereby clamping the indicator disk 200.

[0074] In summary, at least two stoppers are spaced apart on the bracket 100. When the indicator disc 200 is mounted on the bracket 100, the sidewalls of the indicator disc 200 simultaneously abut against the at least two stoppers. This allows the stoppers to clamp the indicator disc 200, thereby securing the indicator disc 200 to the bracket 100. Once the indicator disc 200 is secured to the bracket 100, the relative position between the indicator disc 200 and the bracket 100 remains fixed during use of the electrical switch. Furthermore, by clamping the indicator disc 200 with the stoppers, the step of providing a connecting structure on the indicator disc 200 is eliminated, thereby reducing the manufacturing difficulty and cost of the electrical switch.

[0075] Figure 6 This is an assembly diagram of the knob, indicator plate, and bracket provided in the embodiment of the present application. Figures 4 to 6 As shown, the indicator plate 200 has a first mounting hole 220, and the bracket 100 has a second mounting hole 120. The first mounting hole 220 and the second mounting hole 120 are of the same size and opposite to each other. The driving unit 310 passes through both the first mounting hole 220 and the second mounting hole 120.

[0076] The first mounting hole 220 may be a through hole provided on the indicator plate 200, and the second mounting hole 120 may be a through hole provided on the bracket 100. The center of the first mounting hole 220 may be located opposite the center of the second mounting hole 120. The first mounting hole 220 may be a circular hole, and accordingly, the second mounting hole 120 may also be a circular hole.

[0077] The first mounting hole 220 may be the same size as the second mounting hole 120 , or the second mounting hole 120 may be larger than the first mounting hole 220 .

[0078] When the first mounting hole 220 and the second mounting hole 120 are the same size, the size of the first mounting hole 220 and the second mounting hole 120 can be the same as the cross-sectional size of the driving portion 310. Alternatively, the size of the first mounting hole 220 and the second mounting hole 120 can be slightly larger than the cross-sectional size of the driving portion 310.

[0079] When the size of the second mounting hole 120 is larger than the size of the first mounting hole 220, the size of the first mounting hole 220 can be the same as the size of the cross-section of the driving portion 310, and the size of the second mounting hole 120 can be larger than the size of the cross-section of the driving portion 310. Alternatively, the sizes of the first mounting hole 220 and the second mounting hole 120 can both be larger than the size of the cross-section of the driving portion 310, so that the driving portion 310 can pass through the first mounting hole 220 and the second mounting hole 120.

[0080] Regardless of whether the first mounting hole 220 and the second mounting hole 120 are the same size, or when the size of the second mounting hole 120 is larger than the size of the first mounting hole 220, as long as the driving part 310 can pass through the first mounting hole 220 and the second mounting hole 120 at the same time, the embodiment of the present application does not limit this.

[0081] In summary, the provision of the first mounting hole 220 and the second mounting hole 120 can provide installation space for the driver 310. The first mounting hole 220 and the second mounting hole 120 are of the same size and are positioned opposite each other. This can reduce the probability of difficulty or difficulty in installing the driver 310 due to misalignment between the first mounting hole 220 and the second mounting hole 120 when the driver 310 passes through the first mounting hole 220 and the second mounting hole 120.

[0082] like Figure 3 、 Figure 4 as well as Figure 6 As shown, the bracket 100 includes a first support plate 130, a connecting plate 140 and a second support plate 150 connected in sequence, and the first support plate 130 is arranged parallel to the second support plate 150. The indicator plate 200 is arranged on the first support plate 130, and the second support plate 150 is fixedly connected to the circuit breaker 600.

[0083] The bracket 100 may be formed by sequentially connecting a first support plate 130 , a connecting plate 140 , and a second support plate 150 to form a C-shaped structure.

[0084] like Figure 4As shown, the bracket 100 can also be formed into a circular structure by connecting a first support plate 130, two connecting plates 140, and two second support plates 150. In this arrangement, the first support plate 130 and the two second support plates 150 are arranged in parallel, and the two second support plates 150 are arranged at intervals. One connecting plate 140 connects the first support plate 130 and one second support plate 150, and the other connecting plate 140 connects the first support plate 130 and the other second support plate 150.

[0085] The indicator plate 200 is disposed on a side of the first support plate 130 facing away from the second support plate 150 .

[0086] Through the above arrangement, the first support plate 130 and the second support plate 150 are arranged parallel to each other and connected by the connecting plate 140. This creates a gap between the first support plate 130 and the second support plate 150, facilitating installation of the drive unit 310 through the bracket 100. The indicator plate 200 is mounted on the first support plate 130, and the second support plate 150 is fixedly connected to the circuit breaker 600. This allows the different functions of the bracket 100 to be arranged in blocks, facilitating installation of the electrical switch and reducing the risk of integrating different functions into the same area of ​​the bracket 100, which could lead to incorrect or missing electrical switches during installation.

[0087] Figure 7 This is a schematic diagram of the structure of the hand-operated base provided in the embodiment of the present application. Figure 1 as well as Figure 7 As shown, the manual operating mechanism further includes a manual operating base 400 and a second fastener, and the manual operating base 400 is disposed between the circuit breaker 600 and the bracket 100. The manual operating base 400 and the bracket 100 are fixedly connected by the second fastener.

[0088] The manual operating base 400 can be disposed outside the circuit breaker 600 and can be fixedly connected to the circuit breaker 600. The manual operating base 400 has an installation space inside, and the remaining components of the manual operating mechanism can be installed in the installation space inside the manual operating base 400.

[0089] The bracket 100 can be fixedly connected to the hand-operated base 400 by a second fastener, which can be a bolt. Alternatively, the bracket 100 can also be fixedly connected to the hand-operated base 400 by adhesion or clamping.

[0090] Through the above arrangement, the hand-operated base 400 not only provides installation space for the remaining components of the hand-operated mechanism, but also protects them. Furthermore, the provision of the hand-operated base 400 can share some of the functions of the bracket 100, thereby simplifying the functionality of the bracket 100. This can reduce the cost of repairing or replacing the bracket 100 when it ages or becomes damaged, thereby lowering the cost of using the hand-operated mechanism.

[0091] Figure 8 This is a schematic diagram of the overall structure of the hand-operated mechanism provided in the embodiment of the present application. Figure 4 、 Figure 7 as well as Figure 8 As shown, the second support plate 150 is provided with a third fixing hole 160, and the hand-operated base 400 is provided with a fourth fixing hole 410, which is located opposite to the third fixing hole 160. The second fastener passes through the fourth fixing hole 410 and connects with the third fixing hole 160, so that the hand-operated base 400 and the bracket 100 are fixed by the second fastener.

[0092] In a first configuration, the third fixing hole 160 may be a threaded hole provided on the second support plate 150, and the fourth fixing hole 410 may be a plain hole provided on the hand-operated base 400. In this first configuration, a bolt may first pass through the fourth fixing hole 410 and then be fixedly connected to the third fixing hole 160.

[0093] In a second configuration, the third fixing hole 160 may be a light hole provided on the second support plate 150, and the fourth fixing hole 410 may be a light hole provided on the hand-operated base 400. In this second configuration, a bolt may first pass through the fourth fixing hole 410, then through the third fixing hole 160, and finally be connected with a nut to secure the hand-operated base 400 to the bracket 100.

[0094] Through the above arrangement, a third fixing hole 160 is provided on the second support plate 150, and a fourth fixing hole 410 is provided on the hand-operated base 400, and the bracket 100 can be fixedly connected to the hand-operated base 400 using a second fastener. The third fixing hole 160 and the fourth fixing hole 410 are positioned relative to each other, which can facilitate the installation or removal of the second fastener, and reduce the probability of problems such as difficulty or inability to install the second fastener due to misalignment between the third fixing hole 160 and the fourth fixing hole 410. When fixing the bracket 100 to the hand-operated base 400, the second fastener passes through the fourth fixing hole 410 and the third fixing hole 160 in sequence. This can reduce the probability that the portion of the second fastener that is not connected to the third fixing hole 160 and the fourth fixing hole 410 will interfere with the components within the hand-operated base 400 after installation, thereby improving the reliability of the hand-operated mechanism.

[0095] Combine Figure 1 and Figure 2 The manual operation mechanism further includes an operating rod 500. The operating rod 500 includes a first end 510 and a second end 520 positioned opposite each other. The first end 510 passes through the manual operation base 400 and is connected to the circuit breaker 600. The second end 520 is fixedly connected to the end of the driving part 310 away from the knob 300.

[0096] The operating rod 500 can be in the shape of a rectangular, long rod. It has a first end 510 and a second end 520. The first end 510 passes through the manual operating base 400 and connects to components within the manual operating base 400, thereby connecting to the handle of the circuit breaker 600. The second end 520 can be inserted into the interior of the driving unit 310 and fixedly connected to the knob 300.

[0097] It should be noted that since the operating rod 500 is in the shape of a long rod, when setting the operating rod 500, the knob 300 may be far away from the bracket 100, and a fixed connection between the indicator plate 200 and the bracket 100 cannot be achieved. At this time, the height of the bracket 100 can be adjusted so that the bracket 100 is adapted to the length of the operating rod 500 so that the indicator plate 200 can be fixedly connected to the bracket 100.

[0098] Through the above arrangement, the operating lever 500 establishes a connection between the knob 300 and the circuit breaker 600, thereby enabling the manual operation mechanism to control the internal state transitions of the circuit breaker 600. Furthermore, the manufacturing cost of the operating lever 500 is low, and if the operating lever 500 becomes aged or damaged, the cost of repairing or replacing it is lower, thereby reducing the cost of using the manual operation mechanism.
