Description

Technical Field

[0001] The invention relates to the technical field of busbars used for power distribution, and in particular to an integrated busbar used in a distribution box. Background Art

[0002] In today's electrical field, busbars, as a key device for power transmission and distribution, are widely used in various scenarios. Their performance and structure are of great significance to the stable operation and space utilization of electrical systems.

[0003] With the continuous growth of electricity demand and the increasing diversification and complexity of electrical equipment, higher and higher requirements are placed on the power connection and power distribution capabilities of busbars. Existing busbars usually adopt a structural method of setting installation grooves and placement grooves on the seat body, in which the busbars are installed in the installation grooves, and multiple placement grooves are arranged side by side in the width direction of the seat body to accommodate the busbars. This design concept meets the basic needs of power transmission and distribution to a certain extent, that is, the more busbars there are, the stronger the power connection and power distribution capabilities of the busbars are, and it can provide a stable power supply for more electrical equipment and ensure the normal operation of the electrical system.

[0004] However, this structural design also has obvious limitations. As the number of busbars increases, the width of the busbar body will inevitably increase. In practical applications, this will cause a series of problems. For example, in electrical equipment with limited space, an excessively large busbar body width will occupy too much valuable space, making the internal layout of the equipment more compact and crowded. This will not only bring inconvenience to the assembly and maintenance of the equipment, increase the difficulty and time cost of operation, but may also affect the heat dissipation effect inside the equipment, thereby reducing the overall performance and reliability of the equipment.

[0005] In some special scenarios with high space requirements, such as miniaturized electronic equipment and compact power control cabinets, the problem of large busbar space occupation is particularly prominent. It limits the further miniaturization and integration of equipment and cannot meet the market demand for efficient use of space. Therefore, how to reduce the space occupied by the busbar while ensuring its ability to connect and distribute electrical energy has become a key issue that needs to be urgently solved in the current busbar technology field.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] For reference Figure 1-Figure 21 The present invention is described: Embodiment: An integrated busbar used in a distribution box includes a base body 1, which is made of plastic. The base body 1 serves as the basic supporting structure of the entire busbar and is made of plastic. It has good insulation properties and provides a safe installation environment for internal conductive components.

[0050] The lower side surface of the seat body 1 is provided with a lower mounting groove 2 along its length direction. There are three lower mounting grooves 2, which are arranged at intervals in the width direction of the seat body 1. Lower bus bars 3 are arranged in the lower mounting grooves 2, and the side walls of the lower mounting grooves 2 play a role in isolating adjacent lower bus bars 3. The electrical insulation between the lower bus bars 3 is ensured to prevent the occurrence of faults such as current short circuit. This design enables the lower bus bars 3 to be stably installed in the seat body 1, and they do not interfere with each other during operation, and effectively transmit electrical energy.

[0051] An upper mounting groove 4 is provided on the upper side surface of the seat body 1 along its length direction. The upper mounting groove 4 corresponds to the lower mounting groove 2 in the middle, and an upper bus bar 5 is provided in the upper mounting groove 4. This upper and lower corresponding arrangement is not arranged randomly, but is carefully designed. By forming a certain association between the upper bus bar 5 and the lower bus bar 3 in the middle in the vertical direction, a reasonable spatial layout can be achieved, and it is helpful to optimize the current transmission path and improve the overall performance of the busbar.

[0052] The lower busbar 3 and the upper busbar 5 are both made of copper. Copper has good electrical conductivity and can effectively reduce the loss of electric energy during transmission, ensuring that the current can be stably and efficiently transmitted to various electrical devices. One end of the lower busbar 3 and the upper busbar 5 in the length direction is used to connect to the electrical device to provide the required power input for the electrical device.

[0053] It also includes a long strip of connection bar, which is arranged along the width direction of the seat body 1. The connection bar is electrically connected to the upper bus bar 5 or any one of the lower bus bars 3, so as to realize the further distribution and transmission of electric energy. The two ends of the connection bar extend from the two ends of the width direction of the seat body 1 respectively and form connection terminals. These connection terminals are used as branch lines connecting different electrical equipment, so that the bus can flexibly provide power branch connections for multiple electrical equipment to meet the power supply requirements of complex electrical systems. The connection bar is made of metal copper, which also ensures good electrical conductivity. In addition, there are multiple connection bars, and the multiple connection bars are arranged at intervals in the length direction of the seat body 1. This distribution method helps to evenly distribute electric energy, reduce problems such as heat caused by current concentration, and improve the reliability and stability of the bus.

[0054] A cover 7 is provided on the upper side of the base 1. The main function of the cover 7 is to cover the upper bus bar 5 and the connection bar. On the one hand, the cover 7 protects the internal conductive parts, prevents foreign objects from contacting the bus bar and the connection bar, and avoids safety accidents such as electric shock. On the other hand, the cover 7 also helps to improve the overall aesthetics of the bus bar, making the appearance of the bus bar more neat and standardized, and meeting the installation requirements of electrical equipment.

[0055] The innovation of this busbar lies in its unique structural layout. The existing common four busbars arranged side by side are changed to three busbars arranged side by side on the lower side and another busbar arranged on the upper side in this application, thus forming an upper and lower dislocation structure. Under the condition of the same power connection capacity, this upper and lower dislocation layout makes the structure of the busbar more compact. The traditional side-by-side arrangement will inevitably increase the width of the busbar when the number of busbars is increased to improve the power connection capacity, thereby occupying more space. The design of this application, by rationally utilizing the upper and lower spaces, arranges part of the busbars on the upper side, effectively reduces the size of the busbar in the width direction, so that the busbar occupies less space when in use. This innovative design has significant advantages in the application scenarios of electrical equipment with high space requirements, such as in the fields of miniaturized electronic equipment, compact power control cabinets, etc., which can better meet the conditions of limited internal space of the equipment, provide greater flexibility for the design and layout of electrical equipment, and also improve the utilization of space, which helps to reduce the overall volume and cost of the equipment, and promote the development of electrical equipment in the direction of more miniaturization, integration and efficiency.

[0056] An end seat 8 is provided at one end of the seat body 1 in the longitudinal direction, and the end seat 8 is also made of plastic. The selection of plastic material not only ensures a certain mechanical strength and can provide support for the internal structure, but also has good insulation performance, which can effectively prevent problems such as current leakage and short circuit, and ensure electrical safety. The end seat 8 and the seat body 1 can form a detachable fixed connection.

[0057] A connection groove 9 corresponding to the lower mounting groove 2 is provided on the upper side of the end seat 8. When the lower busbar 3 and the upper busbar 5 extend to the ends, their ends can extend into the corresponding connection groove 9. This design enables the ends of the busbars to be fixed and positioned, ensuring the stability of the current when it is transmitted to the ends. At the same time, the connection groove 9 provides a suitable space and interface for the connection between the busbar and the external power connector 12, which facilitates the further transmission and distribution of electric energy.

[0058] The two sides of the end seat 8 are respectively provided with connection grooves 2 10, and the three connection grooves 1 9 are located between the two connection grooves 2 10, and the three connection grooves 1 9 and the two connection grooves 2 10 are arranged in a row. This unique layout provides a reasonable space arrangement for the subsequent installation and connection of the lap joint 11 and the electrical connection head 12. The connection groove 2 10 is mainly used to accommodate the two ends of the lap joint 11, realize the current diversion and extraction of the upper busbar 5, and provide a basis for increasing the electrical connection points.

[0059] It also includes a U-shaped bridge piece 11, the middle part of which is electrically and fixedly connected to the upper bus bar 5. This connection method ensures that the current of the upper bus bar 5 can be smoothly transmitted to the bridge piece 11. The bridge piece 11 is designed in a U-shape, which is not only easy to install and fix, but also can enhance its structural strength to a certain extent, so that it can stably carry current during operation.

[0060] The two ends of the bridge piece 11 extend into the two connecting grooves 10 respectively, and the two ends of the bridge piece 11 are bent to form power terminals, which are located in the connecting grooves 10. By arranging the power terminals in the connecting grooves 10, on the one hand, the power terminals can be effectively protected and positioned to prevent them from being displaced or damaged due to external forces and other factors; on the other hand, the connecting grooves 10 provide convenient conditions for the connection between the power terminals and the connecting head 12, so that the current can be smoothly transmitted to the external electrical equipment through the connecting head 12.

[0061] The connection slot 1 9 and the connection slot 2 10 are respectively connected with the connection heads 12. The number and position of the connection heads 12 are set according to the layout and connection requirements of the busbars, ensuring that each busbar (including the lower busbar 3 and the upper busbar 5 after being split by the bridging piece 11) can be connected to the corresponding connection head 12 to realize the transmission of electric energy to external electrical equipment.

[0062] The electrical connector 12 is electrically connected to the bridge piece 11 or the lower bus bar 3. The electrical connector 12 is a key component for connecting the busbar to the electrical equipment. The design of the electrical connector 12 needs to meet good electrical conductivity and mechanical connection performance, be able to stably transmit current, and be able to match the interface of the external electrical equipment to ensure the reliability and safety of the connection. Through the electrical connector 12, the busbar can accurately and efficiently transmit electrical energy to various electrical equipment, providing guarantee for the normal operation of the electrical system.

[0063] The terminal seat 8 is provided with a cover body 13, and the cover body 13 covers the ends of the upper busbar 5 and the lower busbar 3, the lap joint 11, and one end of the power connector 12. The cover body 13 plays an important protective role. It can prevent foreign impurities such as dust and moisture from entering the interior of the terminal seat 8, and avoid adverse effects such as corrosion or short circuit on the busbar, the lap joint 11, and the power connector 12, thereby extending the service life of these components and ensuring the stability of the electrical connection. From a safety perspective, the cover body 13 can effectively prevent people from accidentally touching the internal live parts, reducing the risk of electric shock accidents. At the same time, the provision of the cover body 13 also makes the appearance of the end of the busbar more neat and beautiful, meets the normative requirements for the installation of electrical equipment, and improves the overall image of the entire electrical system.

[0064] The setting of the lap joint 11 is of great significance. It can realize the function of increasing the connection points by splitting the upper bus bar 5 into two and arranging them side by side with the three lower bus bars 3. In practical applications, more connection points can provide connection interfaces for more electrical equipment, improving the flexibility and versatility of the busbar. Another function is to guide the upper and lower misaligned bus bars to the same plane and arrange them side by side, so that when the ends are connected, the current distribution is more uniform and reasonable, reducing the heating and other problems that may be caused by uneven current distribution, and also facilitating neat and standardized connection with external electrical equipment.

[0065] The structural design of the busbar end realizes the reasonable connection, diversion and protection of the busbar through the coordinated action of the end seat 8, the lap joint 11, the power connection head 12 and the cover body 13, increases the power connection points, optimizes the current distribution, and improves the reliability and safety of the connection between the busbar and the external electrical equipment. At the same time, it also takes into account the requirements of space utilization and aesthetics, and is an innovative and practical design scheme.

[0066] The two side surfaces of the terminal seat 8 are respectively provided with plug interfaces 14 connected to the connecting groove 2 10, and the plug interfaces 14 are connected to the power terminals 15, and the power terminals 15 are electrically connected to the lap joint 11. This position design is of great significance. The two ends of the lap joint 11 are accommodated in the connecting groove 2 10, and the plug interfaces 14 are connected to the connecting groove 2 10, so that the power terminals 15 can be easily accessed from the side of the terminal seat 8, and can be electrically connected to the lap joint 11. Such a layout fully considers the convenience of space utilization and power connection operation. From a spatial perspective, the side arrangement of the plug interfaces 14 will not increase the size of the terminal seat 8 in other directions, which is conducive to maintaining the compactness of the overall structure of the busbar. From an operational perspective, the side access to the power terminals 15 is more convenient for wiring operations during actual installation and use, thereby improving work efficiency.

[0067] The power terminal 15 is connected to the plug port 14 and is electrically connected to the bridge piece 11. The bridge piece 11 itself plays the role of shunting the upper bus bar 5 and forming a certain degree of side-by-side arrangement with the lower bus bar 3 at the end. By being electrically connected to the bridge piece 11, the power terminal 15 can obtain the current transmitted from the upper bus bar 5, thereby providing a power connection interface for external electrical equipment. This connection method ensures the continuity and stability of current transmission.

[0068] The connection points can be further increased by the connection terminal 15. In actual electrical systems, it is often necessary to connect multiple different electrical devices, and the rich connection points can meet such diverse needs. Increasing the connection points not only improves the flexibility of the busbar, making it easier to connect various types and quantities of electrical devices, but also optimizes the wiring layout of the electrical system to a certain extent, reducing the complexity and confusion of the wiring. For example, in a complex electrical control cabinet, multiple connection points can enable different lines to be connected to the busbar in an orderly manner, avoiding line crossing and confusion, and improving the reliability and maintainability of the electrical system.

[0069] The design of the plug-in interface 14 and the power connection terminal 15 on both sides of the terminal seat 8 is a further expansion and optimization of the power connection function of the busbar. Through the clever layout and connection method, the power connection points are increased without affecting the compactness of the overall structure of the busbar, which improves the applicability and practicality of the busbar and provides strong support for the efficient operation and flexible configuration of the electrical system.

[0070] An insulating isolation block 16 is provided in the connecting groove 1 9 , and the insulating isolation block 16 is located between the lower bus bar 3 and the bridging piece 11 .

[0071] The insulating isolation block 16 is precisely set in the connection groove 9 and is located between the lower bus bar 3 and the bridge piece 11. The selection of this position is carefully considered. The connection groove 9 is the area where the ends of the lower bus bar 3 and the upper bus bar 5 extend into, and the bridge piece 11 is connected to the upper bus bar 5 and part of its structure is located near the connection groove 9. In such a relatively complex electrical connection area, the distance between different conductive parts is relatively close. If there is no effective isolation measure, there will be a great electrical safety hazard.

[0072] The existence of the insulating isolation block 16 effectively blocks the possible electrical path between the upper bus bar 5 and the lower bus bar 3. It has good insulation performance and can withstand a certain voltage without being broken down, thereby ensuring that a sufficient insulation distance is maintained between the upper bus bar 5 and the lower bus bar 3. Even in a complex working environment, such as when there are certain influencing factors such as dust and moisture, the insulating isolation block 16 can effectively prevent the current from flowing along the insulating surface between the upper and lower bus bars 3, avoiding the occurrence of creepage and ensuring the electrical safety performance of the busbar.

[0073] The insulating isolation block 16 located between the lower bus bar 3 and the lap joint 11 provides a reliable insulating barrier between them. It prevents the electric field interaction between the lower bus bar 3 and the lap joint 11, and avoids the creepage phenomenon caused by the uneven electric field. Through this isolation effect, it is ensured that the lower bus bar 3 and the lap joint 11 can work stably and do not interfere with each other, ensuring the accuracy and stability of the overall power transmission and distribution of the busbar.

[0074] The insulating isolation block 16 provided in the connecting groove 9 effectively avoids the creepage phenomenon between the upper bus bar 5 and the lower bus bar 3 and between the lower bus bar 3 and the bridging piece 11 through its electrical isolation function, providing an important guarantee for the safe and reliable operation of the bus, and is an indispensable key component in the bus design.

[0075] The connection bar is electrically connected to the upper bus bar 5 or the lower bus bar 3 by screws. In order to achieve this connection, holes for connecting with screws are provided on the connection bar, the upper bus bar 5 and the lower bus bar 3. As a connecting medium, the size and specification of the screws are usually reasonably selected according to factors such as the current carrying capacity, mechanical strength requirements and installation space of the busbar. This design makes the connection between the connection bar and the busbar have a clear physical structure and connection point, which is convenient for operation and positioning during production and actual installation.

[0076] The screw itself has good electrical conductivity. During the connection process, the current can be smoothly transmitted between the connection bar and the upper bus bar 5 or the lower bus bar 3 through the screw. Compared with some other connection methods, the conductivity of the screw can meet the requirements of the bus for power transmission, and will not cause increased resistance and increased power loss due to the conductivity problems of the connecting parts. Through the screw connection, the connection bar and the upper bus bar 5 or the lower bus bar 3 can form a stable and firm electrical connection. The tightening action of the screw makes the connection bar and the bus bar in close contact, ensuring a good electrical contact area. During the operation of the bus, even if it is subjected to certain vibrations or external forces, the screw connection can remain stable and will not easily loosen or disconnect.

[0077] An isolating plate 17 is provided between adjacent connection bars, and the isolating plate 17 is located between adjacent connection bars, and the upper mounting groove 4 is provided on the upper side of the isolating plate 17. Connection bars are important components for connecting branch lines of different electrical equipment, and they need to maintain good electrical isolation to prevent abnormal conduction of current between adjacent connection bars, thereby avoiding possible electrical faults such as short circuits and leakage. The isolating plate 17 is provided exactly in the middle of adjacent connection bars, forming an effective physical barrier to separate the connection bars and ensure that they work independently in their respective circuit paths without interfering with each other.

[0078] The upper mounting groove 4 is provided on the upper side of the insulating plate 17 .

[0079] The upper ends of the three insulating isolation blocks 16 are connected as a whole by the connecting strip 18. The upper ends of the three insulating isolation blocks 16 are connected as a whole by the connecting strip 18. This connection method enables the three insulating isolation blocks 16 to form a relatively stable overall structure. The connecting strip 18 not only physically connects the three insulating isolation blocks 16, but also realizes the synergy between them in function. In the working environment of the busbar, it may be affected by various external forces and vibrations, and the existence of the connecting strip 18 enhances the overall structural stability of the insulating isolation blocks 16, preventing them from being displaced or deformed under the action of these external factors, so that they can always maintain their accurate position and isolation function inside the busbar.

[0080] The lower bus bar 3 and the connection head 12 are respectively fixedly connected to the lower side of the corresponding insulating isolation block 16. This connection method ensures the position stability of the lower bus bar 3 in the busbar, and at the same time, the insulating effect of the insulating isolation block 16 avoids unnecessary electrical contact between the lower bus bar 3 and other components. The fixed connection between the connection head 12 and the lower side of the insulating isolation block 16 also provides a stable basis for its connection with external electrical equipment, so that electrical energy can be accurately transmitted to the corresponding equipment through the lower bus bar 3 and the connection head 12.

[0081] The lap joint 11 and the upper bus bar 5 are fixedly connected to the upper side of the insulating isolation block 16 located in the middle. This design allows the upper bus bar 5 to be tightly combined with the insulating isolation block 16 in the middle through the lap joint 11, which ensures the fixed position of the upper bus bar 5 on the one hand, and effectively isolates the upper bus bar 5 from other components that may cause electrical interference through the insulating isolation block 16 on the other hand. The connection between the lap joint 11 and the insulating isolation block 16 also facilitates the current shunting of the upper bus bar 5 and the electrical connection with other components, realizing the reasonable layout and efficient operation of the internal electrical structure of the busbar.

[0082] The three lower busbars 3, the upper busbar 5, the lap joint 11, and the power connection head 12 can be fixed together by three insulating isolation blocks 16 connected into one. This pre-fixed assembly method has great advantages. During the production process, these components can be accurately fixed and connected together in a relatively independent work area according to the design requirements. Since the insulating isolation block 16 has been connected into one body and has a clear fixed connection relationship with other power connection structural components, the entire assembly process becomes simpler, more efficient and more accurate. Workers can complete the preliminary assembly of these components in an orderly operating environment, reducing the errors and confusion that may occur in the complex assembly process.

[0083] One-time assembly operation: When assembling the product, the pre-assembled power connection structures can be installed into the base body 1 and the end base 8 at one time, without assembling them one by one. This method greatly saves assembly time and labor costs. Compared with installing components one by one, one-time assembly can significantly improve production efficiency, especially in the case of large-scale production, this advantage is more obvious.

[0084] Simplified assembly process: During assembly, three lower busbars 3 and one upper busbar 5 are inserted into the base body 1 for assembly and fixation, and the insulating isolation block 16, the lap joint 11, and the electrical connector 12 are then installed into the terminal base 8 for assembly and fixation. This clear division of labor and sequence of assembly, based on the connection structure design of the insulating isolation block 16, makes the assembly process clearer and simpler. Workers can operate in an orderly manner according to the established steps, reducing errors and rework caused by the complexity of the assembly process, and further improving assembly efficiency and product quality.

[0085] In summary, by connecting the upper ends of the three insulating isolation blocks 16 into one body with the connecting strip 18 and reasonably fixing them with other power connection structural components, this design not only optimizes the internal structure of the bus and improves the stability of its electrical performance, but also shows significant advantages in the assembly process. Through pre-fixed assembly and one-time assembly, the assembly efficiency is greatly improved, the production cost is reduced, and strong support is provided for the production and application of the bus.

[0086] The seat body 1 is composed of a plurality of busbar units. A plug-in slot 19 is provided on one side of the busbar unit, and a plug-in strip 20 is provided on the other side of the busbar unit. Adjacent busbar units are connected by plugging in the plug-in strip 20 and the plug-in slot 19. A plug-in slot 19 is provided on one side of the busbar unit, and a corresponding plug-in strip 20 is provided on the other side. This design enables adjacent busbar units to be connected by a simple plug-in method. The size and shape of the plug-in slot 19 and the plug-in strip 20 are carefully designed to ensure that they can fit closely and achieve a stable connection. During the plug-in process, the plug-in strip 20 can be accurately inserted into the plug-in slot 19 to form a firm mechanical connection.

[0087] The lower side of the busbar monomer is provided with a lower mounting groove 2 for installing the lower busbar 3. The upper side of the busbar monomer is provided with an insulating plate 17, which serves to isolate adjacent electrical components. The cover body 7 is composed of a plurality of monomer covers 71, and each busbar monomer is connected to a corresponding monomer cover 71. This design enables the cover body to cover the busbar monomer tightly, protecting the internal electrical components from the influence of the external environment, such as dust, moisture, etc. At the same time, the setting of the monomer cover also facilitates the operation of a single busbar monomer during maintenance and overhaul, thereby improving the convenience of maintenance.

[0088] The seat body 1 is composed of a plurality of busbar monomers, so that a busbar of suitable length can be obtained as needed. In different application scenarios, the requirements for the length of the busbar are often different. For example, in a large industrial plant, electrical equipment is widely distributed, and a longer busbar may be required to achieve the distribution of electrical energy; while in a small electronic device, due to limited space, the required busbar length is relatively short. Through this modular design, users can flexibly select the appropriate number of busbar monomers for combination according to actual needs, so as to obtain a busbar that meets specific length requirements. This customizability greatly improves the applicability of the busbar, enabling it to meet the use requirements of various different occasions.

[0089] The busbar monomers are connected by plugging into each other, and the assembly and connection process is very convenient. Compared with some traditional connection methods, such as welding and bolting, plug-in connection does not require complex tools and professional skills, and workers can complete the assembly work in a shorter time. This convenient assembly method not only improves production efficiency and reduces production costs, but also reduces possible errors and damage during the assembly process. In addition, the plug-in connection is also detachable, which means that when the busbar needs to be repaired, replaced or rearranged, the busbar monomer can be easily disassembled and the corresponding operation can be performed without causing permanent damage to the entire busbar. This reusable feature further improves the use value and economy of the busbar.

[0090] The feature of being able to be assembled at will as needed brings great flexibility to the design and application of busbars. In actual electrical systems, the layout and connection methods of electrical equipment may change with factors such as adjustments to production processes, equipment upgrades or modifications. The modular busbar monomer design allows users to reassemble and adjust the busbar at any time according to these changes to adapt to new needs. This flexibility can not only improve the adaptability and scalability of electrical systems, but also reduce the cost and workload of equipment replacement and rewiring caused by system changes.

[0091] The busbar monomers include a first busbar monomer 21 and a second busbar monomer 22 .

[0092] Two insulating plates 17 are provided on the upper side of the first busbar monomer 21, and a space for placing the connection bar is formed between the two insulating plates 17. The function of the insulating plates 17 is to isolate adjacent electrical components to prevent mutual interference and leakage between currents. In this design, the space formed by the two insulating plates 17 provides a specific installation position for the connection bar, so that the connection bar can work in a relatively independent and safe environment. This layout method helps to optimize the electrical structure inside the busbar and improve the stability and reliability of current transmission. A fixing block 23 corresponding to the upper busbar 5 is provided on the upper side of the first busbar monomer 21, and the upper busbar 5 is fixedly connected to the fixing block 23; the specific connection method is that the upper busbar 5 is fixedly connected to the fixing block 23 by screws. The screw connection has the advantages of firm connection and easy disassembly and maintenance.

[0093] Four insulating plates 17 are provided on the upper side of the second busbar monomer 22. The four insulating plates 17 are arranged at intervals to form three spaces for placing the connection bars. Compared with the first busbar monomer 21, the second busbar monomer 22 has more space for placing the connection bars, which means that it can connect more branch lines and has a higher current distribution capacity. This design can meet some application scenarios with high requirements for power distribution. For example, in a large electrical control system, it is necessary to connect multiple electrical equipment with different powers and functions. The structure of the second busbar monomer 22 can better meet this demand.

[0094] The second busbar monomer 22 is provided with three through grooves 24 running through the upper and lower sides thereof, the three through grooves 24 are respectively arranged corresponding to the three lower mounting grooves 2, the three through grooves 24 are respectively arranged in three spaces for accommodating power bars, one of the through grooves 24 is arranged corresponding to the upper bus bar 5, and a detachable partition block 25 is provided between the through groove 24 corresponding to the upper bus bar 5 and the upper bus bar 5, and the partition block 25 forms a detachable connection with the isolation plate 17.

[0095] The provision of the through slot 24 has important functional significance, which allows the lower bus bar 3 to be exposed, so that it can be conveniently electrically connected to the connection bar. This design simplifies the connection method between the lower bus bar 3 and the connection bar, reduces the use of intermediate connection components, reduces resistance loss, and improves the efficiency of power transmission. At the same time, by arranging the through slot 24 corresponding to the placement space of the connection bar, the entire electrical connection structure is made more compact and reasonable, which is conducive to the busbar to achieve more electrical connection functions in a limited space.

[0096] For the through slot 24 corresponding to the upper bus bar 5, a detachable partition block 25 is provided between the through slot 24 and the upper bus bar 5. The partition block 25 is detachably connected to the electric isolation plate 17. The main function of the partition block 25 is to play an electric isolation role when the upper bus bar 5 does not need to be electrically connected to the lower bus bar 3 corresponding to the through slot 24.

[0097] The seat body 1 is composed of a plurality of first bus-bar monomers 21 and second bus-bar monomers 22 , and two first bus-bar monomers 21 are arranged between two adjacent second bus-bar monomers 22 .

[0098] The connection bar includes a first connection bar 61 and a second connection bar 62; the first connection bar 61 is in a straight line shape, and both ends of the first connection bar 61 are bent downward to form connection ends; the second connection bar 62 is arched upward in the middle, and both ends of the second connection bar 62 are bent downward to form connection ends, and the second connection bar 62 arched in the middle corresponds to the interval between the upper bus bar 5 and the lower bus bar 3.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
