Description

Technical Field

[0001] The present invention relates to the field of intelligent distribution boxes, and in particular to an intelligent distribution box. Background Art

[0002] During the use of the distribution box, when the instantaneous current is too large, the relay may become stuck and uncontrollable, and maintenance is required. In the related technology, the current maintenance usually involves directly disconnecting the circuit breaker, removing other structures with physical obstructions, and replacing or repairing the relay, which results in low maintenance efficiency. Summary of the invention

[0003] In order to solve or improve the above-mentioned technical problem of low maintenance efficiency of distribution boxes, one object of the present invention is to provide an intelligent distribution box.

[0004] To achieve the above-mentioned purpose, the present invention provides an intelligent distribution box, comprising: a box body, the box body comprising an installation bottom wall; an insulating partition, arranged in the box body, there is a gap between the insulating partition and the installation bottom wall, and a mounting hole is provided on the insulating partition; a relay, arranged on the installation bottom wall, and a control switch is provided on the relay; a hand dial, passed through the installation hole, and one end of the hand dial extending toward the relay is adapted to the control switch to drive the control switch to move when the hand dial moves.

[0005] According to the intelligent distribution box provided by this application, when the relay in the distribution box is stuck and uncontrollable, the traditional method requires disconnecting the circuit breaker and removing other shielding structures to maintain the relay, which is complicated and time-consuming. However, this solution provides a hand switch, which can directly operate the hand switch located on the outside of the insulating partition when the relay is stuck, drive the control switch of the relay to move, and realize function recovery without complicated disassembly operations, which greatly improves maintenance efficiency.

[0006] Specifically, the intelligent distribution box includes a box body, an insulating partition, a relay and a hand-operated part, wherein the box body includes an installation bottom wall, which is a part of the outer shell structure of the entire distribution box and provides an installation foundation for other components. The relay is installed on the installation bottom wall, so that the installation bottom wall provides a stable installation plane for the relay, ensuring that the relay will not be affected by shaking and other factors during operation. The insulating partition is located inside the box body and is spaced from the installation bottom wall, dividing the inside of the box into different spaces. Since there are electrical components of different voltage levels in the distribution box, the insulating partition can prevent electrical short circuits between different components, ensure the electrical safety of the distribution box, reasonably divide the space in the box, facilitate wiring and component layout, and make the internal structure of the distribution box more regular.

[0007] By setting a mounting hole on the insulating partition, the hand-operated member is inserted into the mounting hole. The mounting hole provides a mounting position for the hand-operated member, so that the hand-operated member can pass through the insulating partition and connect to the control switch of the relay, thereby realizing the operation function under the premise of ensuring insulation.

[0008] The relay is installed on the bottom wall of the installation. The relay is equipped with a control switch, which is compatible with the hand-operated part. The relay is used to control the on and off of the circuit. When there is an instantaneous overcurrent in the circuit, the normal working state of the relay may be affected (such as adhesion). The control switch is the key part of the relay to realize the circuit control function. By operating the control switch with the hand-operated part, the state of the relay can be changed, thereby restoring its normal function or performing fault troubleshooting.

[0009] Among them, one end of the hand switch extending toward the relay is adapted to the control switch to drive the control switch to move when the hand switch moves. When the relay has a fault such as adhesion, the operator can operate the hand switch from the outside of the insulating partition without removing a large amount of structure.

[0010] By moving the hand dial, the control switch of the relay is driven to move, which can change the state of the relay and restore the stuck relay to normal operation or switch it to a safe state, avoiding the tedious operations of traditional maintenance methods and improving maintenance efficiency and the availability of the distribution box.

[0011] In the above technical solution, it can be optionally included: a positioning column, which is arranged on a side of the insulating partition away from the installation bottom wall; a positioning hole, which is arranged on the hand dial, the positioning hole and the positioning column have shapes that match each other, and the positioning hole is sleeved outside the positioning column.

[0012] When operating the hand switch, the cooperation of the positioning column and the positioning hole can ensure the position accuracy of the hand switch during the movement, prevent the hand switch from unnecessary deviation or shaking, thereby more accurately driving the control switch of the relay to move, improving the reliability of operation, and helping to more effectively achieve functional recovery when repairing or adjusting the relay status.

[0013] The positioning column is arranged on the side of the insulating partition away from the mounting bottom wall. The positioning column is a structure extending from the insulating partition and cooperates with the positioning hole on the hand-operated member. Under the action of the positioning column, a positioning reference can be provided for the hand-operated member, so that the hand-operated member can only move in the direction determined by the positioning column during operation, which helps to ensure the accurate cooperation between the hand-operated member and the relay control switch, and avoids the inability to effectively operate the control switch or damage to the control switch due to the position deviation of the hand-operated member.

[0014] In the above technical solution, optionally, the hand-operated part includes: a card plate, the shape of which is adapted to the shape of the mounting hole; a connecting part, which is arranged on one side of the card plate, and one end of the connecting part is adapted to the control switch; a toggle part, which is arranged on the other side of the card plate, and the toggle part and the positioning hole are arranged on opposite sides of the card plate.

[0015] In this solution, the hand-operated member can effectively cooperate with the insulating partition, the relay control switch and the positioning column. The card plate and the mounting hole are adapted to ensure the stable installation of the hand-operated member on the insulating partition, the connecting part realizes the connection with the relay control switch to transmit the operating force, the toggle part facilitates external operation, and the cooperation of the positioning hole and the positioning column improves the accuracy of the operation. The overall structure is compact and the function is clear, which helps to efficiently operate the relay control switch during the maintenance of the distribution box.

[0016] Specifically, the hand-actuated member includes a clamping plate, a connecting portion and a toggling portion, wherein the shape of the clamping plate is adapted to the shape of the mounting hole, and the hand-actuated member is mounted on the insulating partition through the mounting hole of the insulating partition.

[0017] The plate is adapted to the shape of the mounting hole, so that the hand switch can be firmly mounted on the insulating partition. This tight fit prevents the hand switch from shaking or shifting on the insulating partition, ensuring that when the hand switch is operated, its position is relatively fixed, so that the control switch of the relay can be accurately driven to move.

[0018] The connecting part is arranged on one side of the card plate, and one end of the connecting part is adapted to the control switch. Specifically, the connecting part is connected between the card plate of the hand-operated member and the control switch of the relay, and transmits the external operating force of the hand-operated member to the control switch of the relay. When the toggle part is operated, the connecting part can accurately transmit the force to the control switch, so that the control switch moves in the expected manner, thereby changing the state of the relay, for example, when the relay is stuck, the control switch can be moved to restore its normal function.

[0019] The toggle part is arranged on the other side of the card plate, and is arranged on the opposite sides of the card plate with the positioning hole, specifically located on the card plate, opposite to the connecting part, and outside the insulating partition, so as to facilitate the operation of the operator.

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

[0021] The threaded hole is set in the positioning column, and the gasket and the connector are used to further fix the structure related to the positioning column and improve the overall stability of the connection between the hand-operated part and the insulating partition. At the same time, this design is also convenient for disassembly and maintenance of related parts when necessary, ensuring that the positioning and connection relationship between the hand-operated part and the insulating partition is always reliable during the long-term use of the distribution box. Specifically, the threaded hole set in the positioning column is located inside the positioning column, and the end away from the installation bottom wall contacts the gasket.

[0022] The threaded connection allows for a certain degree of adjustment. For example, if during installation it is discovered that the position of the locating post needs to be fine-tuned, this can be achieved by rotating the connector in the threaded hole to ensure an exact fit with the locating hole on the hand lever.

[0023] The gasket is arranged at one end of the threaded hole away from the installation bottom wall, specifically at the end of the threaded hole of the positioning column, contacts the end face of the threaded hole, and is located between the connector and the end face of the threaded hole when the connector is installed.

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

[0025] There is a gap between the gasket and the end face of the positioning hole, so that the hand lever will not be hindered by the gasket when it moves along the axial direction of the positioning column, thereby ensuring the flexibility and smoothness of the operation of the hand lever, helping to more effectively operate the relay control switch and improve the efficiency of maintenance and adjustment.

[0026] When the hand-operated part moves along the positioning column, this gap can prevent the gasket from contacting and interfering with the end face of the positioning hole. If there is no such gap, the gasket may rub or collide with the end face of the positioning hole during the movement of the hand-operated part, increasing the operating resistance and even causing the hand-operated part to fail to move normally, affecting the control and maintenance operations of the relay.

[0027] In the above technical solution, optionally, a connecting hole is provided at one end of the connecting portion facing the control switch, and the control switch extends into the connecting hole; wherein the hand-operated member is rotatably disposed on the insulating partition.

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

[0029] The connection hole and the control switch form a nested connection between the two. When operating the hand switch, this connection method can effectively transmit force and prevent unstable phenomena such as separation or sliding between the control switch and the connection part. Compared with a simple surface contact connection method, this nested structure can withstand greater operating force and is more advantageous when dealing with situations that require greater operating force, such as relay adhesion.

[0030] The rotatable design of the hand lever increases the flexibility of operation, making it easier to operate the relay control switch under different operating requirements and space constraints, while also providing more 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 in a non-circular shape, and the hand-operated member rotates to drive the control switch to rotate.

[0032] By limiting the matching shape of the connection hole and the control switch, the hand lever can not only operate the control switch of the relay by linear movement, but also drive the control switch to rotate by rotation, thus providing more operating dimensions for the control of the relay. This helps to more flexibly adjust the state of the relay in different fault scenarios (such as the relay is stuck and needs to be rotated to remove the sticking state), improves the ability of the distribution box to deal with complex fault conditions, and further enhances the effectiveness of maintenance operations.

[0033] Specifically, at least one of the connection hole and the control switch is in a non-circular shape. If the connection hole is in a non-circular shape, such as an ellipse or a square shape, the major axis and the minor axis are in different directions, and when the connection hole is matched with the control switch, the movement direction of the control switch relative to the connection hole can be limited. If the control switch itself is in a non-circular shape, it can also play a similar limiting role.

[0034] When the hand-operated member rotates, the non-circular connecting hole or control switch can effectively transmit the rotating torque of the hand-operated member to the control switch or the connecting part. Due to the asymmetry of the shape, there will be no relative sliding between the two during the rotation process (under reasonable design conditions), thereby ensuring that the hand-operated member can drive the control switch to rotate accurately.

[0035] The non-circular structure limits unnecessary operations to a certain extent. Compared with the circular structure, it is not easy to cause wrong rotation due to accidental touch. Rotation will only occur when the operating force is applied in a specific direction, which improves the safety and reliability of operation.

[0036] Since at least one of the connection hole and the control switch is non-circular, a torque-transmitting connection relationship is formed between the hand-operated member and the control switch. When the hand-operated member rotates, the rotational motion is transmitted to the control switch through the cooperation between the connection hole and the control switch, so that the control switch also rotates.

[0037] In the above technical solution, optionally, the connection hole and the control switch are in a perfect circle, and the intelligent distribution box also includes: a linkage part, which is passed through the connection hole and the control switch, and the linkage part cooperates with the connection hole, and the linkage part cooperates with the control switch.

[0038] When the connecting hole and the control switch are in a perfect circle, by adding a linkage part, effective connection and precise transmission between the hand lever and the control switch can be ensured, thereby avoiding the problem of sliding or unstable rotation caused by a circular connection and improving the reliability and accuracy of relay control.

[0039] The cross-section of the connection hole and the control switch is circular, and the diameter is designed according to actual needs. The perfect circular shape is relatively simple in processing and manufacturing, which can reduce production costs. At the same time, during the assembly process, the perfect circular connection hole and control switch are also easier to align and install, which improves production efficiency.

[0040] The shape and size of the linkage piece are designed according to the size of the connection hole and the control switch to ensure that it can pass through the connection hole and the control switch smoothly. The linkage piece is arranged through the connection hole and the control switch to connect the connection part of the hand-operated piece with the control switch of the relay.

[0041] When the connection hole and the control switch are in perfect circles, there may be a certain gap between them, resulting in slippage or instability during the transmission process. The addition of the linkage fills these gaps, making the connection between the hand lever and the control switch tighter and more reliable, and effectively transmitting the operating force.

[0042] In the above technical solution, optionally, it includes: a connection box, which is arranged in the box body, and an assembly opening is provided on a side of the connection box away from the installation bottom wall, and the insulating partition is detachably connected to the assembly opening.

[0043] The setting of the connection box and the detachable connection between the insulating partition and the assembly port of the connection box make it easier to operate the insulating partition and its related components (such as hand switches, relays, etc.) during the maintenance, inspection or assembly of the distribution box. This design improves the maintainability and assembly flexibility of the entire distribution box. Specifically, the connection box is arranged in the box body, providing a basic structure for connection and installation of other components (such as insulating partitions), and an assembly port is provided on the side away from the installation bottom wall. The assembly port is detachably connected to the insulating partition, and the connection structure related to the insulating partition is arranged on the connection box, which helps the centralized layout and management of the internal components of the distribution box. The wiring, component installation and other operations related to the insulating partition can be reasonably planned around the connection box, so that the internal structure of the distribution box is more regular and easy to identify and operate.

[0044] The junction box can play a certain role in protecting and isolating the electrical connections and components inside it. For example, it can prevent external factors (such as dust, moisture, etc.) from corroding the connection between the insulating partition and other components, thereby improving the reliability and service life of the entire connection structure.

[0045] The insulating partition can be detachably connected to the assembly port of the connection box, and this detachable connection can be in various ways, such as snap connection, bolt connection, etc. The insulating partition is connected to the connection box through the assembly port and is located on the side of the connection box away from the installation bottom wall. This connection relationship enables the insulating partition to be stably installed on the connection box and is easy to disassemble.

[0046] In the above technical solution, optionally, it includes: a circuit breaker, which is arranged on a side of the insulating partition away from the installation bottom wall, one end of the circuit breaker is used to connect the input cable, and the relay is electrically connected to the circuit breaker.

[0047] Setting up a circuit breaker in the intelligent distribution box and connecting it to the relay will help build a complete circuit protection and control system. The circuit breaker can quickly cut off the circuit when a circuit overload, short circuit or other fault occurs, protecting the safety of the entire circuit system; while the relay can realize 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] The circuit breaker has an internal structure that can automatically cut off the circuit, such as an electromagnetic release, a thermal release, etc., and one end is used to connect the input cable.

[0049] One end of the circuit breaker is connected to the input cable, which introduces the external power supply into the internal circuit of the distribution box, and is electrically connected to the relay, so that the relay can play a control role in the circuit protected by the circuit breaker. The circuit breaker is located on the side of the insulating partition away from the installation bottom wall. This position setting makes the circuit breaker and the relay relatively isolated in space. The insulating partition can prevent possible electrical interference or short circuit between the two, ensuring the normal functioning of their respective functions. By connecting the input cable, electric energy can enter the internal circuit of the distribution box only when the circuit breaker is closed and working normally, and power the relay and subsequent circuits.

[0050] The relay is electrically connected to the circuit breaker so that the relay can operate in the circuit environment protected by the circuit breaker.

[0051] Relays can control the on and off of circuits according to different control signals (such as signals from control systems or sensors). Based on circuit breaker protection, relays can achieve more sophisticated circuit control. For example, in some automated control scenarios, relays can control the on and off of circuits according to the operating status of the equipment or environmental conditions, while circuit breakers provide the final protection measures when circuits fail. The two work together to improve the flexibility and safety of circuit control.

[0052] When a relay fails, such as adhesion, the circuit breaker can prevent the failure from further expanding to the entire circuit system. At the same time, after the relay is repaired (such as restoring the relay function through manual operation), the circuit breaker can be closed again to restore the circuit power supply, so that the entire circuit system can quickly resume normal operation.

DETAILED DESCRIPTION

[0067] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

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

[0069] Refer to the following Figures 1 to 11 An intelligent distribution box provided according to some embodiments of the present invention is described.

[0070] like Figure 1 , Figure 2 , Figure 3 and Fig. 9 As shown, this embodiment provides an intelligent distribution box 100. In the intelligent distribution box 100, when the relay 106 is stuck and uncontrollably, the traditional method requires disconnecting the circuit breaker and removing other shielding structures to maintain the relay 106, which is complicated and time-consuming. However, this solution sets a hand-operated member 108. When the relay 106 is stuck, the hand-operated member 108 located outside the insulating partition 104 can be directly operated to drive the control switch 1062 of the relay 106 to move, thereby realizing functional recovery without the need for complex disassembly operations, which greatly improves maintenance efficiency.

[0071] Specifically, the intelligent distribution box 100 includes a box body 102, an insulating partition 104, a relay 106 and a hand-operated member 108, wherein the box body 102 includes a mounting bottom wall 1022, which is a part of the shell structure of the entire distribution box and provides a mounting base for other components. The relay 106 is mounted on the mounting bottom wall 1022, so that the mounting bottom wall 1022 provides a stable mounting plane for the relay 106, ensuring that the relay 106 will not be affected by shaking and other factors during operation. The insulating partition 104 is located inside the box body 102 and is spaced from the mounting bottom wall 1022, dividing the inside of the box body 102 into different spaces. Since there are electrical components of different voltage levels in the distribution box, the insulating partition 104 can prevent electrical short circuits between different components, ensure the electrical safety of the distribution box, and reasonably divide the space inside the box body 102, which is convenient for wiring and component layout, making the internal structure of the distribution box more regular.

[0072] By setting a mounting hole 1042 on the insulating partition 104, the hand-operated member 108 is inserted into the mounting hole 1042. The mounting hole 1042 provides a mounting position for the hand-operated member 108, so that the hand-operated member 108 can pass through the insulating partition 104 and connect to the control switch 1062 of the relay 106, thereby realizing the operation function under the premise of ensuring insulation.

[0073] The relay 106 is arranged on the installation bottom wall 1022, and a control switch 1062 is arranged on the relay 106, and the control switch 1062 is adapted to the hand-operated member 108. The relay 106 is used to control the on and off of the circuit. When there is a situation such as an instantaneous overcurrent in the circuit, the normal working state of the relay 106 may be affected (such as adhesion). The control switch 1062 is a key part of the relay 106 to realize the circuit control function. By operating the control switch 1062 by the hand-operated member 108, the state of the relay 106 can be changed, thereby restoring its normal function or performing fault troubleshooting.

[0074] Among them, one end of the hand-shift member 108 extending toward the relay 106 is adapted to the control switch 1062 to drive the control switch 1062 to move when the hand-shift member 108 moves. When the relay 106 has a fault such as adhesion, the operator can operate the hand-shift member 108 from the outside of the insulating partition 104 without removing a large amount of structure.

[0075] By moving the hand switch 108, the control switch 1062 of the relay 106 is driven to move, which can change the state of the relay 106, so that the stuck relay 106 can resume normal operation or switch to a safe state, avoiding the cumbersome operations of traditional maintenance methods and improving maintenance efficiency and the availability of the distribution box.

[0076] In one embodiment, optionally, Figure 6 As shown, when the hand dial 108 is operated, the cooperation between the positioning column 1102 and the positioning hole 1104 can ensure the position accuracy of the hand dial 108 during the movement, prevent the hand dial 108 from unnecessary deviation or shaking, thereby more accurately driving the control switch 1062 of the relay 106 to move, improve the reliability of the operation, and help to more effectively achieve functional recovery when repairing or adjusting the status of the relay 106.

[0077] The positioning column 1102 is disposed on a side of the insulating partition 104 away from the mounting bottom wall 1022. The positioning column 1102 is a structure extending from the insulating partition 104 and is matched with the positioning hole 1104 on the hand-operated member 108. Under the action of the positioning column 1102, a positioning reference can be provided for the hand-operated member 108, so that the hand-operated member 108 can only move in the direction determined by the positioning column 1102 during operation, which helps to ensure the accurate cooperation between the hand-operated member 108 and the control switch 1062 of the relay 106, and avoids the inability to effectively operate the control switch 1062 or damage to the control switch 1062 due to the position deviation of the hand-operated member 108.

[0078] When operating the hand switch 108, the positioning column 1102 supports and stabilizes the hand switch 108, reducing the shaking of the hand switch 108. Especially in the case where precise operation of the control switch 1062 is required (such as when dealing with a slight adhesion problem of the relay 106), this stability can improve the success rate of the operation.

[0079] The positioning hole 1104 is located on the hand-operated member 108 and is sleeved outside the positioning column 1102 . The position of the hand-operated member 108 is determined by cooperating with the positioning column 1102 .

[0080] The shape of the positioning hole 1104 matches the positioning column 1102, ensuring that the relative position between the hand-operated member 108 and the insulating partition 104 is fixed and accurate. This precise matching relationship enables the hand-operated member 108 to accurately transmit force to the control switch 1062 of the relay 106 when moving, thereby achieving effective control of the state of the relay 106.

[0081] By being sleeved outside the positioning column 1102, the positioning hole 1104 limits the freedom of the hand dial 108 in the plane, allowing the hand dial 108 to move only along the axial direction of the positioning column 1102, thereby preventing the hand dial 108 from performing unnecessary movements such as rotation or lateral deviation during operation, thereby improving the accuracy and reliability of the operation.

[0082] In one embodiment, optionally, Figure 4 As shown, the hand-operated member 108 can effectively cooperate with the insulating partition 104, the relay 106 control switch 1062 and the positioning column 1102. Among them, the card plate 1082 and the mounting hole 1042 are adapted to ensure the stable installation of the hand-operated member 108 on the insulating partition 104, the connecting portion 1084 realizes the connection with the relay 106 control switch 1062 to transmit the operating force, the toggle portion 1086 facilitates external operation, and the cooperation of the positioning hole 1104 and the positioning column 1102 improves the accuracy of the operation. The overall structure is compact and the function is clear, which helps to efficiently operate the relay 106 control switch 1062 during the maintenance of the distribution box.

[0083] Specifically, the hand-operated member 108 includes a clamping plate 1082 , a connecting portion 1084 and a toggle portion 1086 , wherein the shape of the clamping plate 1082 matches the shape of the mounting hole 1042 , and the hand-operated member 108 is installed on the insulating partition 104 by passing through the mounting hole 1042 of the insulating partition 104 .

[0084] The plate is matched with the mounting hole 1042 in shape, so that the hand-operated member 108 can be firmly mounted on the insulating partition 104. This tight fit prevents the hand-operated member 108 from shaking or shifting on the insulating partition 104, ensuring that when the hand-operated member 108 is operated, its position is relatively fixed, so that the control switch 1062 of the relay 106 can be accurately driven to move.

[0085] To a certain extent, the adaptation of the card plate 1082 and the mounting hole 1042 can play a sealing role, reduce air circulation between different areas in the box 102, help prevent dust, moisture, etc. from spreading between different areas in the box 102 through the mounting hole 1042, and protect the normal operation of internal electrical components.

[0086] The connecting portion 1084 is disposed on one side of the card plate 1082, and one end thereof is adapted to the control switch 1062. Specifically, the connecting portion 1084 is connected between the card plate 1082 of the hand-operated member 108 and the control switch 1062 of the relay 106, and transmits the external operating force received by the hand-operated member 108 to the control switch 1062 of the relay 106. When the toggle portion 1086 is operated, the connecting portion 1084 can accurately transmit the force to the control switch 1062, so that the control switch 1062 moves in an expected manner, thereby changing the state of the relay 106, for example, when the relay 106 is stuck, the control switch 1062 is moved to restore its normal function.

[0087] The design of the connection part 1084 being compatible with the control switch 1062 ensures the accuracy and effectiveness of the connection. Different types of relay 106 control switches 1062 may have different shapes and operation requirements. The adaptable design of the connection part 1084 can meet the connection requirements with various control switches 1062, thereby improving the versatility of the hand-operated member 108.

[0088] The toggle portion 1086 is disposed on the other side of the card plate 1082, and is disposed on opposite sides of the card plate 1082 with the positioning hole 1104. Specifically, it is located on the card plate 1082, opposite to the connecting portion 1084, and is located outside the insulating partition 104, which is convenient for operators to operate.

[0089] The toggle portion 1086 provides an easy-to-operate position for the operator. Since it is located outside the insulating partition 104, the operator can operate it without going deep into the distribution box. This design improves the convenience of operation, especially in emergency maintenance or when the state of the relay 106 needs to be frequently adjusted.

[0090] When the operator operates the toggle part 1086, the toggle part 1086 is isolated from the electrical components (such as the relay 106, the circuit, etc.) in the box 102 by the insulating partition 104, which can reduce the risk of electric shock and improve the safety during the operation. At the same time, the toggle part 1086 is arranged opposite to the positioning hole 1104, so that the matching relationship between the positioning hole 1104 and the positioning column 1102 is not disturbed when the toggle part 1086 is operated, thereby ensuring the accuracy of the operation.

[0091] In one embodiment, optionally, a threaded hole 1122 is provided in the positioning column 1102, and in combination with the gasket 114 and the connector 1124, the structure related to the positioning column 1102 can be further fixed, and the overall stability of the connection between the hand-operated member 108 and the insulating partition 104 can be improved. At the same time, this design also facilitates the disassembly and maintenance of related components when necessary, ensuring that the positioning and connection relationship between the hand-operated member 108 and the insulating partition 104 is always reliable during the long-term use of the distribution box. Specifically, the threaded hole 1122 provided in the positioning column 1102 is located inside the positioning column 1102, and the end away from the mounting bottom wall 1022 contacts the gasket 114.

[0092] An installation position is provided for the connector 1124, and the connection with the connector 1124 is achieved through threaded fitting, so that the positioning column 1102 is fixed or connected to other possible structures (such as the insulating partition 104 or the box body 102 frame, etc.), thereby enhancing the stability of the overall structure.

[0093] The threaded connection allows for a certain degree of adjustment. For example, if during installation it is found that the position of the positioning post 1102 needs to be fine-tuned, this can be achieved by rotating the position of the connector 1124 in the threaded hole 1122 to ensure that it is precisely matched with the positioning hole 1104 on the hand-operated member 108.

[0094] The gasket 114 is disposed at one end of the threaded hole 1122 away from the mounting bottom wall 1022 , specifically at the end of the threaded hole 1122 of the positioning column 1102 , in contact with the end surface of the threaded hole 1122 , and is located between the connector 1124 and the end surface of the threaded hole 1122 when the connector 1124 is installed.

[0095] When the connector 1124 is screwed into the threaded hole 1122, the gasket 114 can disperse the pressure exerted by the connector 1124 on the end face of the threaded hole 1122. This can prevent the connector 1124 from directly squeezing the end face of the threaded hole 1122 of the positioning column 1102, thereby preventing the positioning column 1102 from being damaged (such as thread deformation, cracking, etc.) due to excessive local pressure during long-term use.

[0096] To a certain extent, it plays a sealing role to prevent dust, moisture, etc. from entering the threaded hole 1122 and affecting the reliability of the threaded connection. At the same time, it can also provide a certain buffering effect. For example, when the distribution box is slightly vibrated, the gasket 114 can absorb part of the vibration energy and reduce the impact on the threaded connection.

[0097] The connector 1124 is connected to the threaded hole 1122 of the positioning column 1102 through an external thread, and contacts the gasket 114, thereby fastening the positioning column 1102 to other related structures. By screwing into the threaded hole 1122 and cooperating with the gasket 114, the connector 1124 can firmly fix the position of the positioning column 1102, ensuring that the positioning column 1102 will not shift or loosen during the operation of the distribution box, thereby ensuring the positioning accuracy between the hand-operated member 108 and the positioning column 1102.

[0098] In one embodiment, optionally, Figure 7 and Figure 8 As shown, in the axial direction of the positioning hole 1104, there is a gap L between the gasket 114 and the end face of the positioning hole 1104, so that the hand-operated member 108 will not be hindered by the gasket 114 when moving axially along the positioning column 1102, thereby ensuring the flexibility and smoothness of the operation of the hand-operated member 108, helping to more effectively realize the operation of the relay 106 control switch 1062, and improving the efficiency of maintenance and adjustment.

[0099] When the hand-operated member 108 moves along the positioning column 1102, the gap L can prevent the gasket 114 from contacting and interfering with the end surface of the positioning hole 1104. If there is no gap L, the gasket 114 may rub or collide with the end surface of the positioning hole 1104 during the movement of the hand-operated member 108, increasing the operation resistance, and even causing the hand-operated member 108 to be unable to move normally, affecting the control and maintenance operations of the relay 106.

[0100] Of course, there may be some minor errors or deformations during actual installation and use. The gap L provides a certain margin of error for these uncertainties, so that even if there are some installation errors, the hand-operated member 108 can still operate normally, thereby improving the reliability and stability of the entire device.

[0101] In one embodiment, optionally, Figure 4 and Figure 5 As shown, a connecting hole 1085 is provided at one end of the connecting portion 1084, specifically at the end facing the control switch 1062, which can enhance the connection stability and accuracy between the hand-operated member 108 and the relay 106 control switch 1062, ensure that the state of the relay 106 can be effectively controlled when the hand-operated member 108 is operated, and improve the reliability of the entire distribution box in controlling the relay 106.

[0102] The connection hole 1085 and the control switch 1062 cooperate to form a nested connection between the two. When the hand switch 108 is operated, this connection method can effectively transmit force and prevent the control switch 1062 and the connection part 1084 from being separated or slipped. Compared with a simple surface contact connection method, this nested structure can withstand greater operating force and is more advantageous when dealing with situations such as adhesion of the relay 106 that require greater operating force.

[0103] The control switch 1062 extends into the connection hole 1085, so that the hand-operated member 108 can operate the control switch 1062 more accurately. The size and shape of the connection hole 1085 can be designed according to the specific specifications of the control switch 1062, so as to ensure that the position of the control switch 1062 in the connection hole 1085 is accurate. In this way, when operating the hand-operated member 108, the moving direction and displacement of the control switch 1062 can be controlled more accurately, which helps to adjust the state of the relay 106 more finely, such as in some cases where the function of the relay 106 needs to be fine-tuned.

[0104] The rotatable design of the hand switch 108 increases the flexibility of operation, making it easier to operate the relay 106 control switch 1062 under different operation requirements and space limitations, while also providing 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 control switch 1062 is subject to certain restrictions, the rotatable feature of the hand-operated member 108 allows the operator to operate the control switch 1062 from different angles. For example, when the toggle portion 1086 of the hand-operated member 108 is blocked by other components, the position of the toggle portion 1086 can be adjusted by rotating the hand-operated member 108 for easy operation. This flexibility can improve maintenance efficiency and reduce the difficulties caused by insufficient operating space.

[0106] When troubleshooting the relay 106, the rotatable hand switch 108 can conveniently switch the operation mode. For example, you can first try to observe the reaction of the relay 106 by rotating the hand switch 108, and then operate in a linear direction, which helps to more comprehensively check the working state of the relay 106 and quickly locate the cause of the fault.

[0107] In one embodiment, the matching shape of the limiting connection hole 1085 and the control switch 1062 is optionally such that the hand-operated member 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 operation dimensions for the control of the relay 106. This helps to more flexibly adjust the state of the relay 106 in different fault scenarios (such as the relay 106 is stuck and needs to be rotated to release the sticking state), 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 connection hole 1085 and the control switch 1062 is in a non-circular shape. If the connection hole 1085 is in a non-circular shape, such as an ellipse or a square shape, the directions of its major axis and minor axis are different. When the connection hole 1085 is in cooperation with the control switch 1062, the movement direction of the control switch 1062 relative to the connection hole 1085 can be limited. If the control switch 1062 itself is in a non-circular shape, a similar limiting effect can also be achieved.

[0109] When the hand-operated member 108 rotates, the non-circular connecting hole 1085 or the control switch 1062 can effectively transmit the rotation torque of the hand-operated member 108 to the control switch 1062 or the connecting portion 1084. Due to the asymmetry of the shape, there will be no relative sliding between the two during the rotation process (under the condition of reasonable design), thereby ensuring that the hand-operated member 108 can drive the control switch 1062 to rotate accurately.

[0110] The non-circular structure limits unnecessary operations to a certain extent. Compared with the circular structure, it is not easy to cause wrong rotation due to accidental touch. Rotation will only occur when the operating force is applied in a specific direction, which improves the safety and reliability of operation.

[0111] Since at least one of the connection hole 1085 and the control switch 1062 is non-circular, a torque-transmitting connection relationship is formed between the hand-operated member 108 and the control switch 1062. When the hand-operated member 108 rotates, the rotational motion is transmitted to the control switch 1062 through the cooperation between the connection hole 1085 and the control switch 1062, so that the control switch 1062 also rotates.

[0112] When the relay 106 is stuck or has other faults that need to be solved by turning the control switch 1062, the rotation operation capability of the hand-operated member 108 is particularly important. For example, some internal structures of the relay 106 may be able to release the sticking state or restore the normal mechanical matching relationship when the control switch 1062 is turned. By turning the control switch 1062 by the hand-operated member 108, the fault can be repaired without disassembling the relay 106, which improves the maintenance efficiency and reduces the maintenance cost and downtime.

[0113] In one embodiment, optionally, Fig.11 As shown, when the connecting hole 1085 and the control switch 1062 are in the form of a perfect circle, by adding a linkage member 116, effective connection and precise transmission between the hand-operated member 108 and the control switch 1062 can be ensured, thereby avoiding the problem of sliding or unstable rotation caused by a circular connection, and improving the reliability and accuracy of the control of the relay 106.

[0114] The cross-section of the connection hole 1085 and the control switch 1062 is circular, and the diameter thereof is designed according to actual needs. The shape of a perfect circle is relatively simple in processing and manufacturing, which can reduce production costs. At the same time, during the assembly process, the perfect circle connection hole 1085 and the control switch 1062 are also easier to align and install, thereby improving production efficiency.

[0115] The shape and size of the linkage member 116 are designed according to the size of the connection hole 1085 and the control switch 1062 to ensure that it can smoothly pass through the connection hole 1085 and the control switch 1062. The linkage member 116 is arranged through the connection hole 1085 and the control switch 1062 to connect the connection part 1084 of the manual member 108 with the control switch 1062 of the relay 106.

[0116] When the connection hole 1085 and the control switch 1062 are in perfect circles, there may be a certain gap L between them, resulting in slippage or instability during the transmission process. The addition of the linkage member 116 fills these gaps L, making the connection between the hand-operated member 108 and the control switch 1062 tighter and more reliable, and can effectively transmit the operating force.

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

[0118] In one embodiment, optionally, Figure 6As shown, the setting of the connection box 118 and the detachable connection between the insulating partition 104 and the assembly port 122 of the connection box 118 make it easier to operate the insulating partition 104 and its related components (such as the hand-operated member 108, the relay 106, etc.) during the maintenance, overhaul 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 arranged in the box body 102, providing a basic structure for connection and installation for other components (such as the insulating partition 104), and an assembly port 122 is provided on the side away from the installation bottom wall 1022. The assembly port 122 is detachably connected to the insulating partition 104, and the connection structure related to the insulating partition 104 is arranged on the connection box 118, which is helpful for the centralized layout and management of the internal components of the distribution box. The wiring, component installation and other operations related to the insulating partition 104 can be reasonably planned around the connection box 118, so that the internal structure of the distribution box is more regular and easy to identify and operate.

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

[0120] The insulating partition 104 can be detachably connected to the assembly opening 122 of the connection box 118, and this detachable connection can be in various ways, such as snap connection, bolt connection, etc. The insulating partition 104 is connected to the connection box 118 through the assembly opening 122, and is located on the side of the connection box 118 away from the installation bottom wall 1022. This connection relationship enables the insulating partition 104 to be stably installed on the connection box 118 and is easy to disassemble.

[0121] In one embodiment, optionally, Fig.10 As shown, a circuit breaker 120 is provided in the intelligent distribution box 100 and electrically connected to the relay 106, which helps to build a complete circuit protection and control system. The circuit breaker 120 can quickly cut off the circuit when a fault such as overload or short circuit occurs in the circuit to protect the safety of the entire circuit system; and the relay 106 can realize functions such as on-off control of the circuit according to different control signals. The two work together to improve the ability of the distribution box to control and protect the circuit.

[0122] The circuit breaker 120 has an internal structure capable of automatically cutting off a circuit, such as an electromagnetic release, a thermal release, etc., and one end is used to connect an input cable.

[0123] One end of the circuit breaker 120 is connected to the input cable to introduce the external power supply into the internal circuit of the distribution box, and is electrically connected to the relay 106, so that the relay 106 can play a control role in the circuit protected by the circuit breaker 120. The circuit breaker 120 is arranged on the side of the insulating partition 104 away from the installation bottom wall 1022. This position setting makes the circuit breaker 120 and the relay 106 relatively isolated in space, and the insulating partition 104 can prevent possible electrical interference or short circuit between the two, ensuring the normal functioning of their respective functions.

[0124] When the current in the circuit exceeds the rated current of the circuit breaker 120, the thermal release inside the circuit breaker 120 will automatically operate according to the heat generated by the current, cut off the circuit, and prevent the electrical equipment in the circuit from being damaged due to overload. If a short circuit occurs in the circuit, the large current generated instantly will cause the electromagnetic release inside the circuit breaker 120 to quickly operate and cut off the circuit, thus preventing the short circuit current from causing serious damage to the distribution box and other electrical equipment.

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

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

[0127] Relay 106 can control the on-off of the circuit according to different control signals (such as signals from the control system or sensors). On the basis of the protection of circuit breaker 120, relay 106 can realize more sophisticated circuit control. For example, in some automatic control scenarios, the on-off of the circuit is controlled according to the operating status of the equipment or environmental conditions, while circuit breaker 120 provides the final protection measure when the circuit fails. The two cooperate with each other to improve the flexibility and safety of circuit control.

[0128] When the relay 106 has a fault such as adhesion, the circuit breaker 120 can prevent the fault from further expanding to the entire circuit system. At the same time, after the relay 106 is repaired (such as restoring the function of the relay 106 by operating the hand switch 108), the circuit breaker 120 can be closed again to restore the circuit power supply, so that the entire circuit system can quickly resume normal operation.

[0129] According to the intelligent distribution box provided by the present invention, when the relay is stuck, the hand switch located outside the insulating partition can be directly opened and closed to restore the function and improve the maintenance efficiency.
