Description

Technical Field

[0001] This utility model relates to the field of intelligent distribution boxes, and more specifically, to an intelligent distribution box. Background Technology

[0002] During the use of the distribution box, relays may stick together and become uncontrollable under the condition of excessive instantaneous current, requiring maintenance. In the current technology, maintenance usually involves directly disconnecting the circuit breaker, removing other structures that are physically obstructing it, and replacing or repairing the relay, which is inefficient. Utility Model Content

[0003] In order to solve or improve the technical problem of low maintenance efficiency of the above-mentioned distribution box, one objective of this utility model is to provide an intelligent distribution box.

[0004] To achieve the above objectives, this utility model provides an intelligent distribution box, comprising: a box body, the box body including a mounting bottom wall; an insulating partition disposed inside the box body, with a gap between the insulating partition and the mounting bottom wall, and mounting holes provided on the insulating partition; a relay disposed on the mounting bottom wall, the relay having a control switch; and a manual lever disposed through the mounting holes, one end of the manual lever extending toward the relay being adapted to the control switch so as to drive the control switch to move when the manual lever is moved.

[0005] According to the intelligent distribution box provided in this application, when a relay in the distribution box becomes stuck and uncontrollable, the traditional method requires disconnecting the circuit breaker and removing other obstructing structures to maintain the relay, which is complex and time-consuming. However, this solution, by incorporating a manual lever, allows direct operation of the lever located on the outside of the insulating partition when the relay is stuck, moving the relay's control switch to restore function without requiring complex disassembly, thus significantly improving maintenance efficiency.

[0006] Specifically, the intelligent distribution box includes a cabinet, insulating partitions, relays, and manual levers. The cabinet includes a mounting base, which serves as part of the overall outer structure and provides a mounting foundation for other components. Relays are mounted on the mounting base, which provides a stable mounting surface, ensuring the relays operate normally without being affected by vibrations. The insulating partitions, located inside the cabinet and spaced from the mounting base, divide the interior into different spaces. Since the distribution box contains electrical components of different voltage levels, the insulating partitions prevent short circuits between these components, ensuring electrical safety. The rational division of space within the cabinet facilitates wiring and component layout, resulting in a more organized internal structure.

[0007] A mounting hole is provided on the insulating partition, through which the manual lever is inserted. The mounting hole provides a mounting position for the manual lever, allowing it to pass through the insulating partition and connect to the control switch of the relay, thus achieving the operating function while ensuring insulation.

[0008] The relay is mounted on the mounting wall and has a control switch that is compatible with a toggle switch. The relay is used to control the on / off state of the circuit. When a sudden surge of current occurs in the circuit, the normal operation of the relay may be affected (e.g., sticking). The control switch is the key component for the relay to achieve its circuit control function. By operating the control switch with the toggle switch, the state of the relay can be changed, thereby restoring its normal function or troubleshooting.

[0009] The end of the hand lever extending toward the relay is adapted to the control switch so that the control switch moves when the hand lever moves. In case of relay failure such as sticking, the operator can operate the hand lever from the outside of the insulating partition without dismantling a large amount of the structure.

[0010] By moving the toggle switch, the control switch of the relay can be moved, which can change the state of the relay, allowing a stuck relay to return to normal operation or switch to a safe state. This avoids the cumbersome operation of traditional maintenance methods and improves maintenance efficiency and the availability of the distribution box.

[0011] Optionally, the above technical solution includes: a positioning post located on the side of the insulating partition away from the mounting base wall; and a positioning hole located on the hand lever, the shape of which is adapted to the shape of the positioning post, and the positioning hole being sleeved outside the positioning post.

[0012] When operating the hand lever, the cooperation between the positioning pin and the positioning hole ensures the accuracy of the hand lever's position during movement, preventing unnecessary offset or shaking. This allows for more precise movement of the relay's control switch, improving operational reliability and facilitating more effective functional restoration during relay maintenance or adjustment.

[0013] The positioning post is located on the side of the insulating partition away from the mounting base. Extending from the insulating partition, the positioning post engages with the positioning hole on the manual lever. The positioning post provides a positioning reference for the manual lever, ensuring it can only move in the direction determined by the positioning post during operation. This helps ensure accurate engagement between the manual lever and the relay control switch, preventing ineffective operation or damage to the control switch due to positional deviation of the manual lever.

[0014] In the above technical solution, optionally, the manual lever component includes: a locking plate, the shape of which is adapted to the shape of the mounting hole; a connecting part, disposed on one side of the locking plate, one end of which is adapted to the control switch; and a toggle part, disposed on the other side of the locking plate, the toggle part and the positioning hole being disposed on opposite sides of the locking plate.

[0015] In this design, the manual lever can effectively cooperate with the insulating partition, relay control switch, and positioning post. The matching plate and mounting hole ensure stable installation of the manual lever on the insulating partition; the connecting part enables connection with the relay control switch to transmit operating force; the toggle part facilitates external operation; and the cooperation between the positioning hole and positioning post improves operational accuracy. The overall structure is compact and functionally clear, facilitating efficient operation of the relay control switch during distribution box maintenance.

[0016] Specifically, the hand lever includes a locking plate, a connecting part, and a levering part. The shape of the locking plate is adapted to the shape of the mounting hole. The hand lever is installed on the insulating partition by passing through the mounting hole of the insulating partition.

[0017] The shape of the plate and mounting holes are adapted to fit the insulating plate, allowing the manual lever to be securely mounted on the insulating plate. This tight fit prevents the manual lever from wobbling or shifting on the insulating plate, ensuring that its position is relatively fixed when the manual lever is operated, thereby accurately moving the control switch of the relay.

[0018] The connecting part is located on one side of the lever plate, with one end adapted to the control switch. Specifically, it connects between the lever plate and the control switch of the relay, transmitting the external operating force received by the lever plate to the control switch of the relay. When the lever is operated, the connecting part can accurately transmit the force to the control switch, causing the control switch to move in the expected manner, thereby changing the state of the relay. For example, when the relay is stuck, moving the control switch can restore its normal function.

[0019] The actuating part is located on the other side of the card plate, opposite to the positioning hole on both sides of the card plate. Specifically, it is located on the card plate, opposite to the connecting part, and outside the insulating partition, making it convenient for operators to operate.

[0020] In the above technical solution, optionally, the positioning column is provided with a threaded hole, and the intelligent distribution box includes: a gasket, which is located at the end of the threaded hole away from the mounting bottom wall, and the gasket abuts against the end face of the threaded hole; and a connector, which is provided with an external thread that matches the threaded hole.

[0021] The positioning post features a threaded hole, which, along with a washer and connector, further secures the positioning post's structure and improves the overall stability of the connection between the manual lever and the insulating partition. This design also facilitates disassembly and maintenance of related components when needed, ensuring reliable positioning and connection between the manual lever and the insulating partition throughout the long-term use of the distribution box. Specifically, the threaded hole inside the positioning post, at the end furthest from the mounting base, contacts the washer.

[0022] Threaded connections allow for a degree of adjustment. For example, if the position of the locating pin needs fine-tuning during installation, this can be achieved by rotating the connector within the threaded hole to ensure precise alignment with the locating hole on the hand lever.

[0023] The gasket is located at the end of the threaded hole away from the mounting base wall, specifically at the end of the threaded hole of the positioning post, in contact with the end face of the threaded hole, and is positioned between the connector and the end face of the threaded hole during connector installation.

[0024] In the above technical solution, optionally, there is a gap between the gasket and the end face of the positioning hole in the axial direction of the positioning post.

[0025] There is a gap between the shim and the end face of the positioning hole, so that the hand lever will not be obstructed by the shim when it moves along the axial direction of the positioning post. This ensures the flexibility and smoothness of the hand lever operation, helps to more effectively operate the relay control switch, and improves the efficiency of maintenance and adjustment.

[0026] This clearance prevents the shim from contacting and interfering with the end face of the positioning hole as the manual lever moves along the positioning post. Without this clearance, the shim may rub or collide with the end face of the positioning hole during the movement of the manual lever, increasing operating resistance and potentially preventing the manual lever from moving properly, thus affecting the control and maintenance of the relay.

[0027] In the above technical solution, optionally, the end of the connecting part facing the control switch is provided with a connecting hole, and the control switch extends into the connecting hole; wherein, the hand lever is rotatably provided on the insulating partition.

[0028] By providing a connection hole at one end of the connection part, specifically the end facing the control switch, the connection stability and accuracy between the manual lever and the relay control switch can be enhanced, ensuring that the state of the relay can be effectively controlled when operating the manual lever, thereby improving the reliability of the entire distribution box in terms of relay control.

[0029] The connection hole and the control switch form a nested connection. When the toggle switch is operated, this connection effectively transmits force, preventing instability such as detachment or slippage between the control switch and the connection. Compared to simple surface contact connections, this nested structure can withstand greater operating forces, making it more advantageous in situations requiring significant force, such as dealing with relay sticking.

[0030] The rotatable design of the hand lever increases operational flexibility, making it easier to operate the relay control switch under different operational needs and space constraints, while also providing greater convenience for the layout and maintenance of the distribution box.

[0031] In the above technical solution, optionally, at least one of the connecting hole and the control switch is not circular, and the manual lever rotates to drive the control switch to rotate.

[0032] By restricting the fit between the connection hole and the control switch, the manual lever can not only operate the relay's control switch through linear movement but also rotate to drive the control switch, thus providing more operational dimensions for relay control. This facilitates more flexible adjustment of the relay's state in different fault scenarios (such as when the relay is stuck and needs to be unstuck by rotation), improving the distribution box's ability to cope with complex fault situations and further enhancing the effectiveness of maintenance operations.

[0033] Specifically, at least one of the connecting hole and the control switch is non-circular. If the connecting hole is non-circular, such as being elliptical or square, its major and minor axes will be in different directions. When used with the control switch, this can restrict the direction of movement of the control switch relative to the connecting hole. If the control switch itself is non-circular, it can also play a similar restrictive role.

[0034] When the toggle switch rotates, the non-circular connecting hole or control switch effectively transmits the rotational torque of the toggle switch to the control switch or connecting part. Due to the asymmetry of the shape, no relative slippage occurs between the two during rotation (under proper design), thus ensuring that the toggle switch can drive the control switch to rotate accurately.

[0035] The non-circular structure limits unnecessary operations to some extent. Compared to a circular structure, it is less prone to accidental rotation due to bumps; rotation only occurs when the operating force is applied in a specific direction, thus improving operational safety and reliability.

[0036] Because at least one of the connecting hole and the control switch is not perfectly circular, a torque-transmitting connection is formed between the toggle and the control switch. When the toggle rotates, the rotational motion is transmitted to the control switch through the connection hole and the control switch, causing the control switch to rotate as well.

[0037] In the above technical solution, optionally, the connection hole and the control switch are circular, and the intelligent distribution box also includes: a linkage component, which passes through the connection hole and the control switch, the linkage component cooperates with the connection hole, and the linkage component cooperates with the control switch.

[0038] When the connection hole and the control switch are perfectly circular, by adding a linkage component, the effective connection and precise transmission between the manual lever and the control switch can be ensured, avoiding the problems of slippage or rotational instability that may be caused by the circular connection, thus improving the reliability and accuracy of relay control.

[0039] The connecting holes and control switches have circular cross-sections, with their diameter designed according to actual requirements. The perfectly circular shape is relatively simple to manufacture, reducing production costs. Furthermore, during assembly, the circular connecting holes and control switches are easier to align and install, improving production efficiency.

[0040] The shape and size of the linkage are designed according to the dimensions of the connection hole and the control switch to ensure that it can pass smoothly through the connection hole and the control switch. The linkage passes through the connection hole and the control switch, connecting the connecting part of the manual lever to the control switch of the relay.

[0041] When the connecting hole and the control switch are perfectly circular, there may be a certain gap between them, leading to slippage or instability during transmission. The addition of the linkage fills these gaps, making the connection between the lever and the control switch tighter and more reliable, and effectively transmitting operating force.

[0042] Optionally, the above technical solution includes: a connecting box, disposed inside the housing, with an assembly port on the side of the connecting box away from the mounting bottom wall, and an insulating partition detachably connected to the assembly port.

[0043] The placement of the junction box and the detachable connection between the insulating partition and the junction box mounting port facilitate easier operation of the insulating partition and its related components (such as levers and relays) during the maintenance, repair, or assembly of the distribution box. This design improves the maintainability and assembly flexibility of the entire distribution box. Specifically, the junction box, located inside the box, provides the basic structure for connecting and installing other components (such as the insulating partition). A mounting port is located on the side away from the mounting base, and this port is detachably connected to the insulating partition. Placing the connection structures related to the insulating partition on the junction box helps in the centralized layout and management of the internal components of the distribution box. Wiring and component installation related to the insulating partition can be rationally planned around the junction box, making the internal structure of the distribution box more organized and easier to identify and operate.

[0044] The junction box provides protection and isolation for the internal electrical connections and components. For example, it prevents external factors (such as dust and moisture) from corroding the insulating partitions and the connection points with other components, thereby improving the reliability and service life of the entire connection structure.

[0045] The insulating partition can be detachably connected to the mounting port of the connector box. This detachable connection can be achieved in various ways, such as snap-fit ​​or bolt connection. The insulating partition is connected to the connector box through the mounting port, located on the side of the connector box away from the mounting base. This connection allows the insulating partition to be stably installed on the connector box while facilitating disassembly.

[0046] Optionally, the above technical solution includes: a circuit breaker, located on the side of the insulating partition away from the mounting base wall, one end of the circuit breaker being used to connect an input cable, and a relay being electrically connected to the circuit breaker.

[0047] Installing circuit breakers in intelligent distribution boxes and electrically connecting them to relays helps to build a complete circuit protection and control system. Circuit breakers can quickly disconnect the circuit when faults such as overload or short circuit occur, protecting the safety of the entire circuit system; while relays can perform functions such as on / off control of the circuit according to different control signals. The two work together to improve the distribution box's ability to control and protect the circuit.

[0048] Circuit breakers have internal structures that can automatically disconnect the circuit, such as electromagnetic trip units and thermal trip units, with one end used to connect to the input cable.

[0049] One end of the circuit breaker is connected to the input cable, introducing external power into the internal circuit of the distribution box and electrically connecting to the relay, enabling the relay to perform a control function in the circuit protected by the circuit breaker. The circuit breaker is located on the side of the insulating partition away from the mounting wall. This positioning spatially isolates the circuit breaker and relay, and the insulating partition prevents potential electrical interference or short circuits between them, ensuring the normal functioning of each. Through the input cable connection, electrical energy can only enter the internal circuit of the distribution box to power the relay and subsequent circuits when the circuit breaker is closed and operating normally.

[0050] The relay is electrically connected to the circuit breaker, enabling the relay to operate in the circuit environment protected by the circuit breaker.

[0051] Relays can control the on / off state of circuits based on different control signals (such as signals from control systems or sensors). Building upon circuit breaker protection, relays enable more precise circuit control. For example, in some automated control scenarios, they can control the on / off state of circuits based on the operating status of equipment or environmental conditions, while circuit breakers provide final protection when circuit faults occur. The two work together to improve the flexibility and safety of circuit control.

[0052] When a relay experiences a fault such as sticking, the circuit breaker can prevent the fault from spreading to the entire circuit system. Simultaneously, after the relay is repaired (e.g., its function is restored via a manual lever), the circuit breaker can close again, restoring power to the circuit and enabling the entire circuit system to quickly return to normal operation.

Detailed Implementation

[0067] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0068] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0069] The following reference Figures 1 to 11 This invention describes an intelligent power distribution box provided according to some embodiments of the present invention.

[0070] like Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, this embodiment provides an intelligent distribution box 100. When a relay 106 in the distribution box becomes stuck and uncontrollable, traditional methods require disconnecting the circuit breaker and removing other obstructing structures to maintain the relay 106, which is complex and time-consuming. However, this solution, by providing a manual lever 108, allows direct operation of the lever 108 located outside the insulating partition 104 when the relay 106 is stuck, moving the control switch 1062 of the relay 106 to restore its function. This eliminates the need for complex disassembly operations, significantly improving maintenance efficiency.

[0071] Specifically, the intelligent distribution box 100 includes a box body 102, an insulating partition 104, a relay 106, and a manual lever 108. The box body 102 includes a mounting base 1022, which serves as part of the overall outer shell structure of the distribution box, providing a mounting foundation for other components. The relay 106 is mounted on the mounting base 1022, providing a stable mounting surface and ensuring that the relay 106's normal operation is not affected by factors such as shaking during operation. The insulating partition 104 is located inside the box body 102 and is spaced from the mounting base 1022, dividing the interior of the box body 102 into different spaces. Since the distribution box contains electrical components of different voltage levels, the insulating partition 104 can prevent electrical short circuits between different components, ensuring the electrical safety of the distribution box. The rational division of space within the box body 102 facilitates wiring and component layout, making the internal structure of the distribution box more organized.

[0072] By providing mounting holes 1042 on the insulating partition 104, the manual lever 108 is inserted into the mounting holes 1042. The mounting holes 1042 provide a mounting position for the manual lever 108, allowing it to pass through the insulating partition 104 and connect to the control switch 1062 of the relay 106, thus achieving the operating function while ensuring insulation.

[0073] Relay 106 is mounted on the mounting base 1022. Relay 106 has a control switch 1062, which is compatible with the toggle switch 108. Relay 106 is used to control the on / off state of the circuit. When a sudden surge of current occurs in the circuit, the normal operation of relay 106 may be affected (e.g., sticking). Control switch 1062 is a key component for relay 106 to achieve its circuit control function. By operating control switch 1062 through toggle switch 108, the state of relay 106 can be changed, thereby restoring its normal function or troubleshooting.

[0074] The hand lever 108 extends toward the relay 106 and is adapted to the control switch 1062 so that the control switch 1062 moves when the hand lever 108 moves. When the relay 106 has a fault such as sticking, the operator can operate the hand lever 108 from the outside of the insulating partition 104 without dismantling a large amount of structure.

[0075] By moving the toggle switch 108, the control switch 1062 of the relay 106 can be moved, which can change the state of the relay 106, allowing the stuck relay 106 to return to normal operation or switch to a safe state. This avoids the cumbersome operation of traditional maintenance methods and improves maintenance efficiency and the availability of the distribution box.

[0076] In one embodiment, alternatively, such as Figure 6 As shown, when the hand lever 108 is operated, the cooperation between the positioning pin 1102 and the positioning hole 1104 can ensure the positional accuracy of the hand lever 108 during the movement process, prevent unnecessary offset or shaking of the hand lever 108, thereby more accurately driving the control switch 1062 of the relay 106 to move, improving the reliability of operation, and helping to more effectively restore function when repairing or adjusting the state of the relay 106.

[0077] The positioning post 1102 is located on the side of the insulating partition 104 away from the mounting base wall 1022. As a structure extending from the insulating partition 104, the positioning post 1102 mates with the positioning hole 1104 on the manual lever 108. The positioning post 1102 provides a positioning reference for the manual lever 108, ensuring that the manual lever 108 can only move in the direction determined by the positioning post 1102 during operation. This helps ensure accurate coordination between the manual lever 108 and the relay 106 controlling the switch 1062, preventing ineffective operation of the control switch 1062 or damage to the control switch 1062 due to positional deviation of the manual lever 108.

[0078] When operating the lever 108, the positioning post 1102 provides support and stability to the lever 108, reducing its wobbling. This stability is particularly beneficial in situations requiring precise operation of the control switch 1062 (such as when dealing with a slight sticking issue with the relay 106), improving the success rate of operation.

[0079] The positioning hole 1104 is located on the hand lever 108 and is sleeved on the positioning post 1102. The position of the hand lever 108 is determined by its cooperation with the positioning post 1102.

[0080] The shape of the positioning hole 1104 is adapted to the positioning post 1102, ensuring that the relative position between the manual lever 108 and the insulating partition 104 is fixed and accurate. This precise fit allows the manual lever 108 to accurately transmit force to the control switch 1062 of the relay 106 when it moves, thereby achieving effective control of the state of the relay 106.

[0081] By fitting around the positioning post 1102, the positioning hole 1104 restricts the freedom of the hand lever 108 in the plane, allowing the hand lever 108 to move only along the axial direction of the positioning post 1102, preventing unnecessary movements such as rotation or lateral displacement of the hand lever 108 during operation, thereby improving the accuracy and reliability of operation.

[0082] In one embodiment, alternatively, such as Figure 4 As shown, the manual lever 108 can effectively cooperate with the insulating partition 104, the relay 106 control switch 1062, and the positioning post 1102. The locking plate 1082 and the mounting hole 1042 ensure stable installation of the manual lever 108 on the insulating partition 104. The connecting part 1084 connects with the relay 106 control switch 1062 to transmit operating force. The toggle part 1086 facilitates external operation, and the cooperation between the positioning hole 1104 and the positioning post 1102 improves operational accuracy. The overall structure is compact and functionally clear, facilitating efficient operation of the relay 106 control switch 1062 during distribution box maintenance.

[0083] Specifically, the manual lever 108 includes a locking plate 1082, a connecting part 1084, and a lever part 1086. The shape of the locking plate 1082 is adapted to the shape of the mounting hole 1042. The manual lever 108 passes through the mounting hole 1042 of the insulating partition 104 and is mounted on the insulating partition 104.

[0084] The shape of the plate matches the mounting hole 1042, allowing the manual lever 108 to be securely mounted on the insulating partition 104. This tight fit prevents the manual lever 108 from wobbling or shifting on the insulating partition 104, ensuring that its position is relatively fixed when the manual lever 108 is operated, thereby accurately driving the control switch 1062 of the relay 106 to move.

[0085] To a certain extent, the fit between the card plate 1082 and the mounting hole 1042 can play a sealing role, reducing air circulation between different areas inside the enclosure 102, which helps prevent dust, moisture and other substances from spreading between different areas inside the enclosure 102 through the mounting hole 1042, thus protecting the normal operation of the internal electrical components.

[0086] A connecting part 1084 is located on one side of the latch plate 1082, with one end adapted to the control switch 1062. Specifically, it connects between the latch plate 1082 of the manual lever 108 and the control switch 1062 of the relay 106. The connecting part 1084 transmits the external operating force received by the manual lever 108 to the control switch 1062 of the relay 106. When the lever 1086 is operated, the connecting part 1084 can accurately transmit the force to the control switch 1062, causing the control switch 1062 to move in the expected manner, thereby changing the state of the relay 106. For example, when the relay 106 is stuck, its normal function can be restored by moving the control switch 1062.

[0087] The design of the connector 1084, which is adapted to the control switch 1062, ensures the accuracy and effectiveness of the connection. Different types of relays 106 and control switches 1062 may have different shapes and operating requirements. The adaptability design of the connector 1084 can meet the connection needs with various control switches 1062, improving the versatility of the toggle switch 108.

[0088] The actuating part 1086 is located on the other side of the card plate 1082, and is located on the opposite sides of the positioning hole 1104 on the card plate 1082. Specifically, it is located on the card plate 1082, opposite to the connecting part 1084, and is located outside the insulating partition 104, which facilitates operation by the operator.

[0089] The toggle switch 1086 provides an easily accessible location for the operator. Because it is located outside the insulating partition 104, the operator can access it without needing to penetrate deep into the distribution box. This design improves ease of operation, especially in emergency repairs or when frequent adjustments to the relay 106 are required.

[0090] When the operator operates the toggle unit 1086, the risk of electric shock is reduced and the safety during operation is improved because it is isolated from the electrical components (such as the relay 106 and wiring) inside the housing 102 by the insulating partition 104. Simultaneously, its opposite arrangement to the positioning hole 1104 ensures that operating the toggle unit 1086 does not interfere with the fit between the positioning hole 1104 and the positioning post 1102, guaranteeing operational accuracy.

[0091] In one embodiment, optionally, a threaded hole 1122 is provided in the positioning post 1102, which, together with the gasket 114 and the connector 1124, can further fix the structure related to the positioning post 1102 and improve the overall stability of the connection between the manual lever 108 and the insulating partition 104. At the same time, this design also facilitates the disassembly and maintenance of related components when needed, ensuring that the positioning and connection between the manual lever 108 and the insulating partition 104 remain reliable during the long-term use of the distribution box. Specifically, the threaded hole 1122 provided in the positioning post 1102 is located inside the positioning post 1102, with one end away from the mounting base wall 1022 contacting the gasket 114.

[0092] The mounting position is provided for the connector 1124, and the connection with the connector 1124 is achieved through threaded engagement, thereby fixing or connecting the positioning post 1102 with other possible structures (such as the insulating partition 104 or the frame of the box 102, etc.) to enhance the stability of the overall structure.

[0093] The threaded connection allows for a certain degree of adjustment. For example, if the position of the positioning pin 1102 needs to be finely adjusted during installation, it can be achieved by rotating the connector 1124 in the threaded hole 1122 to ensure precise engagement with the positioning hole 1104 on the hand lever 108.

[0094] The gasket 114 is located at the end of the threaded hole 1122 away from the mounting base wall 1022, specifically at the end of the threaded hole 1122 of the positioning post 1102, and contacts the end face of the threaded hole 1122. When the connector 1124 is installed, it is located between the connector 1124 and the end face of the threaded hole 1122.

[0095] When the connector 1124 is screwed into the threaded hole 1122, the washer 114 can disperse the pressure applied by the connector 1124 to the end face of the threaded hole 1122. This can prevent the connector 1124 from directly pressing the end face of the threaded hole 1122 of the positioning post 1102, and avoid damage to the positioning post 1102 (such as thread deformation, cracking, etc.) due to excessive local pressure during long-term use.

[0096] To a certain extent, it acts as a seal, preventing dust, moisture, and other contaminants from entering the threaded hole 1122 and affecting the reliability of the threaded connection. Simultaneously, it provides a certain degree of cushioning; for example, when the distribution box experiences slight vibrations, the gasket 114 can absorb some of the vibration energy, reducing the impact on the threaded connection.

[0097] The connector 1124 is connected to the threaded hole 1122 of the positioning post 1102 via an external thread and contacts the washer 114, thus securing the positioning post 1102 together with other related structures. By screwing into the threaded hole 1122 and engaging with the washer 114, the connector 1124 can firmly fix the position of the positioning post 1102, ensuring that the positioning post 1102 will not shift or loosen during the operation of the distribution box, thereby guaranteeing the positioning accuracy between the hand lever 108 and the positioning post 1102.

[0098] In one embodiment, alternatively, such as Figure 7 and Figure 8 As shown, in the axial direction of the positioning hole 1104, there is a gap L between the shim 114 and the end face of the positioning hole 1104, so that the hand lever 108 will not be obstructed by the shim 114 when it moves along the axial direction of the positioning post 1102, thereby ensuring the flexibility and smoothness of the operation of the hand lever 108, which helps to more effectively realize the operation of the relay 106 to control the switch 1062, and improve the efficiency of maintenance and adjustment.

[0099] When the manual lever 108 moves along the positioning post 1102, this gap L prevents the shim 114 from contacting and interfering with the end face of the positioning hole 1104. Without this gap L, the shim 114 may rub or collide with the end face of the positioning hole 1104 during the movement of the manual lever 108, increasing the operating resistance and potentially causing the manual lever 108 to fail to move normally, affecting the control and maintenance of the relay 106.

[0100] Of course, some minor errors or deformations may occur during actual installation and use. The gap L provides a certain tolerance for these uncertainties, allowing the manual lever 108 to still operate normally even with some installation errors, thus improving the reliability and stability of the entire device.

[0101] In one embodiment, alternatively, such as Figure 4 and Figure 5 As shown, a connection hole 1085 is provided at one end of the connection part 1084, specifically at the end facing the control switch 1062. This enhances the connection stability and accuracy between the manual lever 108 and the relay 106 control switch 1062, ensuring that the state of the relay 106 can be effectively controlled when the manual lever 108 is operated, thereby improving the reliability of the entire distribution box in terms of relay 106 control.

[0102] The connection hole 1085 and the control switch 1062 form a nested connection. When the toggle switch 108 is operated, this connection effectively transmits force, preventing instability such as disengagement or slippage between the control switch 1062 and the connection part 1084. Compared to a simple surface contact connection, this nested structure can withstand greater operating force, making it more advantageous in situations requiring greater operating force, such as when the relay 106 is stuck.

[0103] The control switch 1062 extends into the connection hole 1085, allowing for more precise operation of the control switch 1062 by the toggle switch 108. The size and shape of the connection hole 1085 can be designed according to the specific specifications of the control switch 1062, ensuring accurate positioning of the control switch 1062 within the connection hole 1085. This allows for more precise control of the direction and amount of movement of the control switch 1062 when operating the toggle switch 108, facilitating finer adjustments to the state of the relay 106, such as in situations requiring minor adjustments to the relay 106's function.

[0104] The rotatable design of the hand lever 108 increases operational flexibility, making it easier to operate the relay 106 to control the switch 1062 under different operational needs and space constraints. It also provides more convenience for the layout and maintenance of the distribution box.

[0105] When the internal space of the distribution box is limited or the operating direction of the relay 106 controlling the switch 1062 is restricted, the rotatable feature of the toggle switch 108 allows the operator to operate the control switch 1062 from different angles. For example, when the toggle part 1086 of the toggle switch 108 is obstructed by other components, the position of the toggle part 1086 can be adjusted by rotating the toggle switch 108 to facilitate operation. This flexibility can improve maintenance efficiency and reduce difficulties caused by insufficient operating space.

[0106] When troubleshooting relay 106, the rotatable lever 108 allows for easy switching of operating modes. For example, one can first try rotating the lever 108 to observe the response of relay 106, and then perform linear operation. This helps to more comprehensively check the working status of relay 106 and quickly locate the cause of the fault.

[0107] In one embodiment, optionally, the mating shape of the connection hole 1085 and the control switch 1062 is restricted, so that the manual lever 108 can not only operate the control switch 1062 of the relay 106 by linear movement, but also drive the control switch 1062 to rotate by rotation, thereby providing more operational dimensions for the control of the relay 106. This helps to more flexibly adjust the state of the relay 106 under different fault scenarios (such as when the relay 106 is stuck and needs to be unstuck by rotation), improves the ability of the distribution box to cope with complex fault conditions, and further enhances the effectiveness of maintenance operations.

[0108] Specifically, at least one of the connecting hole 1085 and the control switch 1062 is non-circular. If the connecting hole 1085 is non-circular, for example, elliptical or square, its major and minor axes are in different directions. When it cooperates with the control switch 1062, it can restrict the direction of movement of the control switch 1062 relative to the connecting hole 1085. If the control switch 1062 itself is non-circular, it can also play a similar restrictive role.

[0109] When the lever 108 rotates, the non-circular connecting hole 1085 or the control switch 1062 can effectively transmit the rotational torque of the lever 108 to the control switch 1062 or the connecting part 1084. Due to the asymmetry of the shape, no relative slippage will occur between the two during rotation (under reasonable design), thereby ensuring that the lever 108 can drive the control switch 1062 to rotate accurately.

[0110] The non-circular structure limits unnecessary operations to some extent. Compared to a circular structure, it is less prone to accidental rotation due to bumps; rotation only occurs when the operating force is applied in a specific direction, thus improving operational safety and reliability.

[0111] Since at least one of the connecting hole 1085 and the control switch 1062 is not perfectly circular, a torque-transmitting connection is formed between the manual lever 108 and the control switch 1062. When the manual lever 108 rotates, the rotational motion is transmitted to the control switch 1062 through the cooperation of the connecting hole 1085 and the control switch 1062, causing the control switch 1062 to rotate as well.

[0112] When relay 106 experiences sticking or other malfunctions requiring rotation of control switch 1062, the rotary capability of the toggle switch 108 becomes particularly important. For example, certain internal structures of relay 106 may be released from sticking or have their normal mechanical engagement restored when control switch 1062 is rotated. By rotating control switch 1062 using toggle switch 108, the malfunction can be attempted to be repaired without disassembling relay 106, improving maintenance efficiency and reducing maintenance costs and downtime.

[0113] In one embodiment, alternatively, such as Figure 11 As shown, when the connecting hole 1085 and the control switch 1062 are perfectly circular, by adding the linkage 116, the effective connection and precise transmission between the hand lever 108 and the control switch 1062 can be ensured, avoiding the problem of slippage or rotational instability that may be caused by the circular connection, and improving the reliability and accuracy of the control of the relay 106.

[0114] The cross-sections of the connecting hole 1085 and the control switch 1062 are circular, with their diameters designed according to actual requirements. The circular shape is relatively simple to manufacture, reducing production costs. Furthermore, during assembly, the circular connecting hole 1085 and the control switch 1062 are easier to align and install, improving production efficiency.

[0115] The shape and size of the linkage 116 are designed according to the dimensions of the connection hole 1085 and the control switch 1062 to ensure that it can pass smoothly through the connection hole 1085 and the control switch 1062. The linkage 116 passes through the connection hole 1085 and the control switch 1062, connecting the connecting part 1084 of the manual lever 108 to the control switch 1062 of the relay 106.

[0116] When the connecting hole 1085 and the control switch 1062 are perfectly circular, there may be a certain gap L between them, which may cause slippage or instability during transmission. The addition of the linkage 116 fills these gaps L, making the connection between the hand lever 108 and the control switch 1062 tighter and more reliable, and effectively transmitting the operating force.

[0117] The design of the linkage 116 ensures that the movement of the manual lever 108 is accurately transmitted to the control switch 1062, avoiding errors caused by loose connections or gaps L. This helps improve the accuracy of control over the relay 106 and ensures the normal operation of the distribution box.

[0118] In one embodiment, alternatively, such as Figure 6As shown, the arrangement of the connection box 118 and the detachable connection between the insulating partition 104 and the assembly port 122 of the connection box 118 facilitate the operation of the insulating partition 104 and its related components (such as the manual lever 108, relay 106, etc.) during the maintenance, repair, or assembly of the distribution box. This design improves the maintainability and assembly flexibility of the entire distribution box. Specifically, the connection box 118 is located inside the enclosure 102, providing a basic structure for the connection and installation of other components (such as the insulating partition 104). The assembly port 122 is located on the side away from the mounting bottom wall 1022, and is detachably connected to the insulating partition 104. Setting the connection structure related to the insulating partition 104 on the connection box 118 facilitates the centralized layout and management of the internal components of the distribution box. Wiring, component installation, and other operations related to the insulating partition 104 can be rationally planned around the connection box 118, making the internal structure of the distribution box more organized and easier to identify and operate.

[0119] The junction box 118 can provide a certain degree of protection and isolation for the internal electrical connections and components. For example, it prevents external factors (such as dust, moisture, etc.) from corroding the connection between the insulating partition 104 and other components 1084, thereby improving the reliability and service life of the entire connection structure.

[0120] The insulating partition 104 can be detachably connected to the mounting port 122 of the connecting box 118. This detachable connection can be made in various ways, such as snap-fit ​​connection or bolt connection. The insulating partition 104 is connected to the connecting box 118 through the mounting port 122 and is located on the side of the connecting box 118 away from the mounting bottom wall 1022. This connection relationship allows the insulating partition 104 to be stably installed on the connecting box 118 while also facilitating disassembly.

[0121] In one embodiment, alternatively, such as Figure 10 As shown, installing a circuit breaker 120 in the intelligent distribution box 100 and electrically connecting it to a relay 106 helps to build a complete circuit protection and control system. The circuit breaker 120 can quickly disconnect the circuit when overload, short circuit, or other faults occur, protecting the safety of the entire circuit system; while the relay 106 can perform functions such as circuit on / off control according to different control signals. The two work together to improve the distribution box's ability to control and protect the circuit.

[0122] Circuit breaker 120 has an internal structure that can automatically disconnect the circuit, such as an electromagnetic trip unit or a thermal trip unit, and one end is used to connect the input cable.

[0123] One end of the circuit breaker 120 is connected to an input cable, introducing external power into the internal circuit of the distribution box, and is electrically connected to the relay 106, enabling the relay 106 to perform a control function in the circuit protected by the circuit breaker 120. The circuit breaker 120 is located on the side of the insulating partition 104 away from the mounting base 1022. This positioning spatially isolates the circuit breaker 120 and the relay 106, and the insulating partition 104 prevents potential electrical interference or short circuits between them, ensuring the normal functioning of each.

[0124] When the current in the circuit exceeds the rated current of circuit breaker 120, the thermal trip unit inside circuit breaker 120 will automatically activate based on the heat generated by the current, cutting off the circuit and preventing damage to electrical equipment in the circuit due to overload. If a short circuit occurs, the instantaneous large current will cause the electromagnetic trip unit inside circuit breaker 120 to quickly activate, disconnecting the circuit and preventing the short circuit current from causing serious damage to the distribution box and other electrical equipment.

[0125] By connecting the input cable, electrical energy can only enter the internal circuit of the distribution box to power the relay 106 and subsequent circuits when the circuit breaker 120 is closed and operating normally.

[0126] The relay 106 is electrically connected to the circuit breaker 120, enabling the relay 106 to operate in the circuit environment protected by the circuit breaker 120.

[0127] Relay 106 can control the circuit's on / off state based on different control signals (such as signals from the control system or sensors). Building upon the protection provided by circuit breaker 120, relay 106 enables more precise circuit control. For example, in some automated control scenarios, it can control the circuit's on / off state based on the equipment's operating status or environmental conditions. Meanwhile, circuit breaker 120 provides final protection when a circuit fault occurs. The two work together to improve the flexibility and safety of circuit control.

[0128] When relay 106 experiences a fault such as sticking, circuit breaker 120 can prevent the fault from spreading to the entire circuit system. Simultaneously, after repairing relay 106 (e.g., restoring relay 106's function via manual lever 108), circuit breaker 120 can close again, restoring power to the circuit and enabling the entire circuit system to quickly return to normal operation.

[0129] According to the intelligent distribution box provided by this utility model, when the relay becomes stuck, the function can be restored by directly opening and closing the manual lever located on the outside of the insulating partition, thereby improving maintenance efficiency.
