Description

Technical Field

[0001] This application relates to the field of power supply and distribution busbar equipment technology, and more specifically, to a split-type terminal busbar power distribution unit. Background Technology

[0002] As a key component of power distribution systems, terminal busbar distribution units are widely used in industrial plants, commercial buildings, data centers, and other scenarios. They bear the core function of distributing electrical energy from the busbar system to end-user equipment, and their performance directly affects the stability, safety, and operational efficiency of the power distribution system. With the increasing demands of modern buildings and industrial facilities for power distribution flexibility and ease of expansion, the structural design and functional adaptability of terminal busbar distribution units have become a focus of industry attention.

[0003] Currently, most mainstream terminal busbar distribution units in the industry adopt an integrated enclosure structure, which integrates all electrical components into a single, indivisible enclosure. The enclosure size is adjusted as the function expands or the current capacity changes. For example, when it is necessary to add distribution function modules such as circuit breakers and surge protectors, a larger integrated enclosure must be replaced simultaneously, resulting in a wide variety of enclosure types. Customized design and processing are required during the manufacturing process to meet different needs.

[0004] Existing technologies have significant drawbacks: First, the integrated structure leads to a high degree of diversity in enclosure types, a large demand for customized production, inconsistent assembly processes, and a lack of interchangeability between enclosures, resulting in increased production costs and wasted resources. Second, the enclosure volume increases with functional expansion, resulting in high space occupancy and poor adaptability in confined power distribution environments. Third, the low integration of components necessitates complete disassembly for maintenance, which is complex, affects the operation of adjacent equipment, and leads to low maintenance efficiency. In addition, although some existing designs (such as the rail-mounted busbar unit in publication number CN210744450U) have attempted modular improvements, they still suffer from problems such as complex structures, insufficient component interchangeability, and limited load adaptability. Summary of the Invention

[0005] The main objective of this application is to provide a modular combination structure for a split-type terminal busbar distribution unit, which solves the technical problems of diverse box types, high customization costs, complex maintenance, and low space utilization in the existing integrated distribution unit. It achieves the technical effects of improved structural flexibility, optimized production and operation efficiency, enhanced space adaptability, improved system reliability, and upgraded intelligent management.

[0006] To achieve the above objectives, this application proposes a split-type terminal busbar power distribution unit, configured with a modular assembly structure, comprising: The power distribution module is directly or indirectly connected to the busbar assembly.

[0007] At least one power supply module is detachably grounded to the power distribution function module and is detachably grounded to the busbar assembly.

[0008] The power acquisition module is equipped with a power acquisition end and a power connection end. The power acquisition end is electrically connected to the busbar assembly, and the power connection end is connected to the power distribution function module. The number of power acquisition ends and power connection ends are the same and they correspond one-to-one.

[0009] The split-type terminal busbar power distribution unit in the above structure is configured as a modular assembly structure. Specifically, it may include a power distribution function module and at least one power intake module.

[0010] Specifically, the power distribution module is directly or indirectly connected to the power supply module. Its core function is to integrate electrical functions such as power distribution, protection, and monitoring (e.g., circuit breakers, surge protectors, metering modules), enabling power distribution and safety management of terminal electrical equipment. Functions can be flexibly configured according to load requirements, and application scenarios cover industrial equipment power distribution, commercial building lighting systems, data center server power supply, etc. This disclosure can decompose the functions of a traditional integrated enclosure into independent modules.

[0011] The power acquisition module electrically connects the power distribution function module to the busbar assembly, establishing a power transmission channel between the busbar assembly and the power distribution function module. This enables flexible combination and power transfer of the modular structure, supporting rapid replacement and expansion of the power distribution function module. The power acquisition module is suitable for scenarios requiring frequent adjustments to the power distribution scheme (such as laboratory equipment upgrades and production line modifications), and can achieve compatibility between different modules through a unified interface.

[0012] The power intake end can obtain power from the busbar assembly, while the power connection end outputs power to the power distribution module. The one-to-one correspondence between the two ensures the stability and accuracy of power transmission and avoids electrical faults caused by incorrect connections. The application scenario is suitable for power distribution systems with high reliability requirements (such as power supply for medical equipment and financial data centers). A one-to-one power transmission path can be achieved through quantity matching.

[0013] In some examples, there are two power supply modules, namely a first module and a second module. The first module is connected to the first side of the power distribution function module, and the second module is connected to the second side of the power distribution function module.

[0014] The number of power terminals on the first module is different from the number of power terminals on the second module.

[0015] This setup avoids incorrect connections caused by confusion between the left and right modules during installation, thus improving the accuracy and safety of the installation.

[0016] In some examples, the power take-off terminal is a contact spring, with the first end of the contact spring connected to the power receiving terminal and the second end of the contact spring able to abut against and be electrically connected to the busbar assembly.

[0017] The aforementioned contact spring has good elasticity and conductivity. Its first end is fixedly connected to the receiving end to ensure that electrical energy can be smoothly transmitted from the receiving end to the contact spring. The second end of the contact spring can abut against the busbar assembly to achieve a reliable electrical connection.

[0018] The connection between the first end of the contact spring and the power receiving end can be achieved by welding, screw connection, snap-fit, or by integrating the connection between the first end of the contact spring and the power receiving end into one unit.

[0019] The above structure not only ensures the stability of power transmission, but also adapts to minor deformations or installation errors of the busbar components to a certain extent, thereby improving the compatibility and reliability of the entire power distribution unit.

[0020] In some examples, the contact spring is a composite spring, which includes a first spring and a second spring that are connected to each other. The first spring is directly electrically connected to the bus body in the bus assembly, and the second spring is attached to the first spring.

[0021] The first spring sheet has a U-shaped reinforcing structure at the contact position with the main body of the busbar, and the second spring sheet extends at least partially into the U-shaped groove of the U-shaped reinforcing structure, with a receiving protrusion at the end of the second spring sheet.

[0022] The aforementioned composite spring design significantly enhances the overall strength and stability of the contact spring. The U-shaped reinforcement structure not only provides additional support for the first spring, effectively preventing deformation due to stress during long-term use, but also better disperses pressure, ensuring a tighter and more reliable contact with the busbar body.

[0023] The second spring is attached to the first spring and extends partially into the U-shaped groove of the U-shaped reinforcement structure. This structure further increases the contact area between the two springs and improves the conductivity.

[0024] Meanwhile, the receiving protrusion design at the end of the second spring can play a certain role in buffering and positioning when subjected to external force, preventing the second spring from slipping off the first spring and further ensuring the stability of the electrical connection.

[0025] In some examples, the end of the contact spring near the main body of the busbar has a multi-branched structure.

[0026] This multi-branched structure can improve service life. Specifically, when the contact spring approaches the busbar body, multiple branches can simultaneously contact the busbar body. Under normal operating conditions, multiple branches share the current transmission task, effectively distributing the current, reducing the current carrying pressure on individual branches, and reducing the risk of overheating and damage caused by excessive current.

[0027] In some examples, the power connection is a plug structure, and the power distribution module is equipped with a flexible clamp that is compatible with the plug structure.

[0028] The aforementioned pin structure and flexible clamp design provide a robust and convenient connection between the power distribution module and the power take-off module of the split-type terminal busbar power distribution unit. The pin structure is typically made of highly conductive metal, and its shape and size are standardized to ensure smooth insertion into the flexible clamp and a tight electrical connection.

[0029] In some examples, each set of power take-off and power connection terminals is provided with an independent insulating shell.

[0030] The aforementioned independent insulating enclosure provides several significant advantages for the split-type terminal busbar distribution unit.

[0031] The independent insulating outer shell effectively isolates each power take-off and connection point, preventing electric shock accidents caused by accidental contact or short circuits, thus improving operator safety during use. This insulation protection is particularly important in locations with frequent personnel operations or complex environments, such as industrial production workshops and commercial building power distribution rooms.

[0032] In some examples, the power take-up module is snapped onto the busbar assembly, and the power distribution function module has two power take-up modules on each side. The power distribution function module is indirectly connected to the busbar assembly through the two power take-up modules.

[0033] The aforementioned snap-fit ​​connection method enables the assembly of split-type terminal busbar distribution units using a snap-fit ​​mechanism. This snap-fit ​​structure simplifies and speeds up the connection between the power take-up module and the busbar assembly. Operators do not need complex tools; they simply align the power take-up module with the corresponding snap-fit ​​position on the busbar assembly and press gently to complete the installation, significantly reducing installation time and improving efficiency. This convenient installation method is particularly valuable in large-scale power distribution system installation projects, significantly saving manpower and time costs.

[0034] In some examples, the snap-fit ​​components on the power supply module include a first snap, a second snap, a transmission mechanism, and a control component.

[0035] The first latch is set and engaged on the first side of the busbar assembly, the second latch is set and engaged on the second side of the busbar assembly, the transmission end of the transmission mechanism is connected to one of the first latch or the second latch, the drive end of the transmission mechanism is connected to the control component, and the control component is at least partially located on the outer periphery of the power extraction module.

[0036] The busbar assembly has matching slot structures on both sides.

[0037] When the control element is triggered, at least one of the first or second latches is released by the transmission mechanism.

[0038] The aforementioned snap-fit ​​assembly enhances the convenience and flexibility of installing and disassembling the split-type terminal busbar distribution unit. In practice, the operator only needs to trigger the control component located on the outer periphery of the power take-up module to disengage at least one of the first or second snap-fits from the busbar assembly via the transmission mechanism. This design avoids the cumbersome process of operating multiple snap-fits simultaneously or using complex tools, as required by traditional connection methods, significantly improving operational efficiency.

[0039] The first and second latches are respectively located on both sides of the busbar assembly and are interconnected through a transmission mechanism to ensure the stability and reliability of the connection. When the latches engage with the slot structures on both sides of the busbar assembly, a secure connection is formed, effectively preventing the power extraction module from loosening or falling off due to vibration or external forces during operation. This double-sided latching design also enhances the electrical connection performance between the power extraction module and the busbar assembly, reduces contact resistance, and improves the efficiency of power transmission.

[0040] The control unit enhances operational safety and convenience. Positioning the control unit on the outer periphery of the power supply module eliminates the need for direct contact with live parts when triggering it, reducing the risk of electric shock. Furthermore, the triggering method of the control unit can be diversified to meet various user habits and operating environments, such as button-type or toggle-type triggers.

[0041] In some examples, at least one of the first and second snap-fits is a double snap-fit ​​structure, and the corresponding side of the busbar assembly is provided with two slot structures spaced apart. The double snap-fit ​​structure can snap into the two slot structures simultaneously.

[0042] This dual-clamping structure further enhances the stability and reliability of the connection between the power extraction module and the busbar assembly. In practical applications, the dual-clamping structure simultaneously engages with two spaced-apart slots on the corresponding sides of the busbar assembly, creating a double-fixing effect. Even under strong vibrations or external impacts, it effectively prevents the power extraction module from loosening, shifting, or even falling off, greatly ensuring the stability of the electrical connection and guaranteeing continuous and stable power transmission.

[0043] The technical solutions provided by the embodiments of this application may include the following beneficial effects: In this application, by setting the split-type terminal busbar power distribution unit as a modular combination structure, and adopting technical solutions such as detachable electrical connection between the power distribution function module and the power take-up module, one-to-one correspondence between the power take-up end and the power receiving end of the power take-up module, differentiated power receiving end design for dual power take-up modules, and integration of contact spring-type power take-up end and status indicator light, multiple technical effects are achieved, including improved structural flexibility, optimized production and operation efficiency, enhanced space adaptability, improved system reliability, and upgraded intelligent management. This effectively solves the industry pain points of traditional integrated power distribution unit, such as diverse box types, high customization costs, and complex maintenance.

[0060] The disclosed end-of-line busbar distribution unit can refer to the End-of-Line Busbar Distribution Unit in the electrical field, that is, a dedicated power distribution device for end-of-line power distribution systems, used to centrally distribute electrical energy and ensure the stable operation of electrical equipment. This design integrates busbar connection and power distribution control functions, which can simplify the power distribution link, improve power transmission efficiency, and ensure electrical safety and ease of operation.

[0061] Electrical engineers can use terminal busbar distribution units to provide centralized power distribution and safety protection for electrical equipment during computer room construction or industrial equipment power distribution. These distribution units need to have modular expansion capabilities to adjust power distribution capacity according to load requirements. For functional terminal busbar distribution units, the reliability of busbar connections, the flexibility of branch control, and the adaptability of protection levels all significantly impact the user experience. Existing terminal busbar distribution unit designs are mostly geared towards fixed load scenarios, with limited interface compatibility for devices of different power ratings and poor scalability. Insufficient interfaces can restrict device access, while excessive redundancy leads to resource waste. Therefore, a new type of terminal busbar distribution unit is needed.

[0062] Reference Figures 1 to 10 This disclosure provides a split-type terminal busbar power distribution unit. The split-type terminal busbar power distribution unit provided by this disclosure is specifically designed for terminal power distribution scenarios. It adopts a modular splicing structure, has a high enclosure protection level, and excellent heat dissipation performance. It is suitable for connecting busbar systems and providing stable power distribution and intelligent monitoring for multiple electrical devices.

[0063] To facilitate the description of the structure of the terminal busbar distribution unit, unless otherwise specified, this manual describes the structure of the distribution unit with the direction of the incoming line terminal as the top when the distribution unit is naturally installed. The "inner side" refers to the surface that directly contacts the busbar conductor, located on the side of the distribution unit closest to the busbar. Furthermore, the terms "front," "back," "left," "right," "up," and "down" in this manual are defined with the direction the operating panel faces as the front when the distribution unit is in its normal installation state.

[0064] As an example, Figures 1 to 4 A schematic diagram of a modularly assembled split-type terminal busbar distribution unit provided according to an embodiment of the present disclosure is shown.

[0065] Reference Figures 1 to 4 In some examples, the split-type terminal busbar distribution unit is configured as a modular combined structure, including: The power distribution module 100 is directly or indirectly connected to the busbar assembly 300.

[0066] At least one power supply module 200 is detachably grounded to the power distribution function module 100 and is detachably grounded to the bus assembly 300.

[0067] The power acquisition module 200 is equipped with a power acquisition terminal 210 and a power receiving terminal 220. The power acquisition terminal 210 is electrically connected to the bus assembly 300, and the power receiving terminal 220 is point-connected to the power distribution function module 100. The number of power acquisition terminals 210 and power receiving terminals 220 are the same and they correspond one-to-one.

[0068] The split-type terminal busbar power distribution unit in the above structure is configured as a modular assembly structure. Specifically, it may include a power distribution function module 100 and at least one power extraction module 200.

[0069] Specifically, the power distribution module 100 is directly or indirectly connected to the busbar assembly 300. Its core function is to integrate electrical functions such as power distribution, protection, and monitoring (e.g., circuit breakers, surge protectors, metering modules), enabling power distribution and safety management of terminal electrical equipment. Functions can be flexibly configured according to load requirements, and application scenarios cover industrial equipment power distribution, commercial building lighting systems, data center server power supply, etc. This disclosure can decompose the functions of a traditional integrated enclosure into independent modules.

[0070] The power acquisition module 200 can electrically connect the power distribution module 100 to the busbar assembly 300, establishing a power transmission channel between the busbar assembly 300 and the power distribution module 100. This enables flexible combination and power transfer of the modular structure, supporting rapid replacement and expansion of the power distribution module 100. The power acquisition module 200 is suitable for scenarios requiring frequent adjustments to the power distribution scheme (such as laboratory equipment upgrades and production line modifications), and can achieve compatibility between different modules through a unified interface.

[0071] The power intake end 210 can obtain power from the bus assembly 300, and the function of the power connection end 220 is to output power to the power distribution module 100. The one-to-one correspondence between the two can ensure the stability and accuracy of power transmission and avoid electrical faults caused by incorrect connection. The application scenario is suitable for power distribution systems with high reliability requirements (such as power supply for medical equipment and financial data centers). A one-to-one power transmission path can be achieved through quantity matching.

[0072] The modular combination structure of the aforementioned split-type terminal busbar power distribution unit achieves multiple overall beneficial effects through the detachable electrical connection between the power distribution function module 100 and the power extraction module 200: First, the split-type terminal busbar power distribution unit improves structural flexibility. It can flexibly combine or replace the power distribution function modules 100 according to the load requirements and functional expansion requirements of the terminal electrical equipment (such as adding protection modules and metering modules), without having to replace the entire power distribution unit, which greatly reduces the equipment replacement cost.

[0073] Secondly, the production and operation and maintenance efficiency of the split-type terminal busbar power distribution unit is optimized. The standardized power take-up module 200 can be mass-produced, and the power distribution function module 100 can be customized as needed, reducing the customized production pressure caused by the diversity of box types. At the same time, the independent disassembly design of the module makes fault diagnosis and component replacement more convenient, shortening the operation and maintenance downtime.

[0074] Third, the modular terminal busbar distribution unit has enhanced spatial adaptability. The modular design allows the volume of the distribution unit to be flexibly adjusted according to the actual functional configuration, and space can be used efficiently even in a small power distribution environment.

[0075] Fourth, the system reliability of the split-type terminal bus distribution unit is improved. The one-to-one correspondence design between the power take-off end 210 and the power receiving end 220 avoids the risk of misconnection. The double snap-fit ​​structure and other detailed designs further ensure the stability of electrical connections and reduce the occurrence rate of power distribution failures.

[0076] In a further example, the power distribution module 100 can encompass various types, such as a monitoring module with intelligent monitoring capabilities, which can monitor key parameters of the bus system in real time, such as voltage, current, and temperature, and transmit the data to a remote control center. A protection module with protection functions can quickly disconnect the circuit in case of abnormal conditions such as short circuits or overloads, ensuring the safety of electrical equipment and the bus system. The power take-up module 200 can be designed in different specifications according to different power requirements. Its power take-up terminal 210 and power connection terminal 220 adopt a standardized interface design, facilitating quick and reliable connection and disconnection with the bus assembly 300 and the power distribution module 100, greatly improving installation and maintenance efficiency.

[0077] Reference Figures 3 to 6In some examples, there are two power supply modules 200, namely a first module 200a and a second module 200b. The first module 200a is connected to the first side of the power distribution function module 100, and the second module 200b is connected to the second side of the power distribution function module 100. The number of power connection terminals 220 on the first module 200a is different from the number of power connection terminals 220 on the second module 200b.

[0078] This setup avoids incorrect connections caused by confusion between the left and right modules during installation, thus improving the accuracy and safety of the installation.

[0079] For example, in some application scenarios that require distinguishing between left and right side connections, such as power distribution in data center server racks, the first module 200a can be set with more power terminals 220 to meet the main power supply requirements, while the second module 200b is set with fewer power terminals 220 for backup or auxiliary power supply. At the same time, the difference in quantity is used to prevent mistaken insertion by operators.

[0080] Furthermore, the two power supply modules 200 are connected from both sides of the power distribution module 100, making the power transmission path more dispersed, reducing the risk of the entire power distribution unit failing due to a single-sided connection failure, and improving the reliability and stability of the system.

[0081] In practical applications, when one power supply module 200 experiences poor contact or other malfunctions, the other power supply module 200 can still operate normally, providing power to the power distribution module 100 and ensuring the continuous operation of the electrical equipment. Furthermore, this dual-sided connection design also facilitates heat dissipation. With the two power supply modules 200 located on opposite sides of the power distribution module 100, it increases airflow space, improves heat dissipation efficiency, and prevents localized overheating from affecting the performance and lifespan of the power distribution unit.

[0082] Furthermore, taking the busbar assembly 300 as an example with five busbar bodies 310, the number of power connection terminals 220 on the first module 200a and the number of power connection terminals 220 on the second module 200b can be set to combinations such as 1-4, 2-3, 3-2, 4-1.

[0083] In some examples, the power take-off terminal 210 is a contact spring 211, the first end of which is connected to the power take-off terminal 220, and the second end of which can abut against and be electrically connected to the bus assembly 300.

[0084] The aforementioned contact spring 211 has good elasticity and conductivity. Its first end is fixedly connected to the power receiving end 220 to ensure that electrical energy can be smoothly transmitted from the power receiving end 220 to the contact spring 211. The second end of the contact spring 211 can abut against the busbar assembly 300 to achieve a reliable electrical connection.

[0085] The connection between the first end of the contact spring 211 and the power terminal 220 can be achieved by welding, screw connection, snap-fit, or by integrating the first end of the contact spring 211 and the power terminal 220 into a single unit.

[0086] The above structure not only ensures the stability of power transmission, but also can adapt to minor deformations or installation errors of the busbar assembly 300 to a certain extent, thereby improving the compatibility and reliability of the entire power distribution unit.

[0087] For example, in scenarios with high requirements for electrical connections, such as power supply for precision instruments or power distribution for high-precision production lines, contact spring 211 can provide a stable and low-resistance connection, effectively reducing power loss and heat generation, and ensuring the normal operation of the equipment.

[0088] Meanwhile, the material of the contact spring 211 is usually a metal material with excellent conductivity and a certain degree of elasticity, such as copper alloy. After special surface treatment process, its conductivity and corrosion resistance are further improved, and its service life is extended.

[0089] Reference Figures 7 to 10 In some examples, the contact spring 211 is a composite spring, which includes a first spring 2111 and a second spring 2114 connected to each other. The first spring 2111 is directly electrically connected to the bus body 310 in the bus assembly 300, and the second spring 2114 is attached to the first spring 2111.

[0090] The first spring piece 2111 is provided with a U-shaped reinforcing structure 2112 at the contact position with the busbar body 310, the second spring piece 2114 extends at least partially into the U-shaped groove 2113 of the U-shaped reinforcing structure 2112, and a receiving protrusion 2115 is provided at the end of the second spring piece 2114.

[0091] The aforementioned composite spring design significantly enhances the overall strength and stability of the contact spring 211. The U-shaped reinforcing structure 2112 not only provides additional support for the first spring 2111, effectively preventing it from deforming due to stress during long-term use, but also better disperses pressure, ensuring a tighter and more reliable contact with the busbar body 310.

[0092] The second spring 2114 is attached to the first spring 2111 and extends partially into the U-shaped groove 2113 of the U-shaped reinforcing structure 2112. This structure further increases the contact area between the two springs and improves the conductivity.

[0093] Meanwhile, the receiving protrusion 2115 at the end of the second spring 2114 can play a certain role in buffering and positioning when subjected to external force, preventing the second spring 2114 from slipping off the first spring 2111, and further ensuring the stability of the electrical connection.

[0094] In practical applications, this composite spring can adapt to more complex and harsh working environments, providing strong support for the reliable operation of split-type terminal busbar distribution units.

[0095] Reference Figures 8 to 10 In some examples, the end of the contact spring 211 near the busbar body 310 has a multi-branched structure.

[0096] This multi-branch structure can improve service life. Specifically, when the contact spring 211 approaches the busbar body 310, multiple branches can simultaneously contact the busbar body 310. Under normal operating conditions, multiple branches share the current transmission task, effectively dispersing the current, reducing the current carrying pressure on a single branch, and reducing the risk of overheating and damage due to excessive current.

[0097] In actual use, various factors inevitably affect the system, and some branches may break or fail. However, due to the adoption of a multi-branch structure, even if some branches have problems, the other intact branches can still maintain an effective connection with the main busbar 310, ensuring that electrical energy can be transmitted continuously and stably. The failure of individual branches will not affect the normal operation of the entire power distribution unit, greatly improving the reliability and stability of the contact spring 211.

[0098] For example, in scenarios with high requirements for power supply stability, such as hospital operating rooms and large data centers, this multi-branched contact spring 211 can provide uninterrupted power supply to electrical equipment, avoiding problems such as equipment downtime or data loss due to poor contact, and ensuring the normal operation of critical tasks.

[0099] This configuration extends the service life of the contact spring 211, reduces the frequency of replacement and maintenance, and lowers the cost of use.

[0100] In some examples, the power connection 220 is a plug structure, and the power distribution module 100 is provided with an elastic clamp adapted to the plug structure.

[0101] The aforementioned pin structure and the flexible clamp provide a stable and convenient connection between the power distribution module 100 and the power take-up module 200 of the split-type terminal busbar power distribution unit. The pin structure is typically made of highly conductive metal, and its shape and size are standardized to ensure smooth insertion into the flexible clamp and a tight electrical connection.

[0102] The flexible clamp is installed on the power distribution module 100. Because the flexible clamp has a certain elastic deformation capacity, when the pin structure is inserted, the flexible clamp can deform appropriately to tightly clamp the pin structure, thus ensuring a firm and reliable connection between the two, preventing loosening or detachment. This connection method is not only convenient to install and disassemble, but also can withstand certain external forces, such as vibration and impact, ensuring a stable electrical connection in various working environments.

[0103] In practical applications, the design of the latch structure and the flexible clamp also provides a certain degree of protection against misinsertion. By rationally designing the shape and size of the latch, as well as the opening direction and size of the flexible clamp, only the correctly matched latch can be inserted into the corresponding flexible clamp, thereby avoiding electrical faults or equipment damage caused by misinsertion.

[0104] Furthermore, this connection method also boasts excellent versatility and interchangeability. Different specifications and models of power distribution modules 100 and power take-off modules 200 can be freely combined and replaced, provided their pin structures and elastic clamps are compatible, thus meeting the needs of different users and application scenarios.

[0105] Reference Figures 7 to 10 In some examples, each set of power take-off terminals 210 and power receiving terminals 220 is provided with an independent insulating housing 230.

[0106] The aforementioned independent insulating enclosure 230 provides significant advantages to the split-type terminal busbar distribution unit in many aspects.

[0107] The independent insulating housing 230 effectively isolates each set of power take-off terminals 210 and power receiving terminals 220, preventing electric shock accidents caused by accidental contact or short circuits, and improving the safety of operators during use. This insulation protection is particularly important in places with frequent personnel operations or complex environments, such as industrial production workshops and commercial building power distribution rooms.

[0108] The independent insulating enclosure 230 helps improve the anti-interference capability of the entire power distribution unit. In electrical systems, electromagnetic interference may exist between different circuits, affecting signal transmission and normal equipment operation. The independent insulating enclosure 230 can physically isolate each power take-off terminal 210 and power receiving terminal 220, reducing the mutual influence of electromagnetic interference, ensuring the stability and accuracy of power transmission, and guaranteeing the normal operation of electrical equipment.

[0109] The above structure facilitates individual maintenance and repair of each power take-off terminal 210 and power receiving terminal 220. When a power take-off terminal 210 or power receiving terminal 220 malfunctions, maintenance personnel can easily open the corresponding insulating shell 230 to conduct a detailed inspection and repair of that part without affecting other normally functioning parts. This not only improves maintenance efficiency and reduces maintenance time, but also reduces the risk of damage to other parts due to improper maintenance operations.

[0110] Furthermore, the independent insulating housing 230 can be manufactured using materials with different properties to suit various usage environments and requirements. For example, in locations with high fire resistance requirements, materials with good fire-retardant properties can be selected. In environments with high corrosion resistance requirements, materials with strong corrosion resistance can be chosen. This allows for better adaptation to various complex usage environments and extends the service life of the power distribution unit.

[0111] In the power distribution systems of some chemical plants, the presence of various chemical substances in the environment necessitates high corrosion resistance from the power distribution equipment. Using an independent insulating enclosure 230 with corrosion resistance effectively protects the power take-up terminal 210 and the power receiving terminal 220 from chemical corrosion, ensuring the long-term stable operation of the power distribution unit. Simultaneously, in densely populated areas such as large shopping malls and high-rise buildings, where electrical safety requirements are extremely high, the independent insulating enclosure 230 provides reliable electrical isolation, protecting personnel safety.

[0112] The insulating shell 230 can be made of flame-retardant ABS material, which has high temperature resistance and impact resistance.

[0113] In some examples, the power take-up module 200 is snapped onto the bus assembly 300, and the power distribution function module 100 is provided with a power take-up module 200 on each side. The power distribution function module 100 is indirectly connected to the bus assembly 300 through the two power take-up modules 200.

[0114] The aforementioned snap-fit ​​connection method enables the assembly of split-type terminal busbar distribution units using a snap-fit ​​mechanism. This snap-fit ​​structure simplifies and speeds up the connection between the power take-up module 200 and the busbar assembly 300. Operators do not need complex tools; they simply align the power take-up module 200 with the corresponding snap-fit ​​position on the busbar assembly 300 and press gently to complete the installation, significantly reducing installation time and improving efficiency. This convenient installation method is particularly valuable in large-scale power distribution system installation projects, significantly saving manpower and time costs.

[0115] The snap-fit ​​structure provides reliable connection force. Through a well-designed snap-fit ​​system, optimizing parameters such as the shape, size, and elasticity of the snap-fit, the power module 200 and busbar assembly 300 can be tightly connected, preventing loosening. During equipment operation, even under external forces such as vibration and impact, a stable electrical connection is maintained, ensuring the continuity and reliability of power transmission. This is crucial for locations with extremely high requirements for power supply stability, such as hospital intensive care units and bank data centers, effectively preventing power outages due to loose connections and ensuring the normal operation of critical equipment.

[0116] Furthermore, the design of the snap-fit ​​structure can be flexibly adjusted according to actual needs. For example, various forms of snap-fit ​​structures can be designed based on different busbar assembly 300 specifications and power extraction module 200 types to achieve the best connection effect. Simultaneously, the snap-fit ​​structure can be combined with other functional designs, such as heat dissipation structures and insulation structures, to further improve the overall performance of the split-type terminal busbar power distribution unit. For instance, in some high-power power distribution scenarios, heat dissipation channels can be designed around the snap-fit ​​structure, utilizing the gaps during snap-fit ​​connection to promote airflow, enhance heat dissipation, and ensure the stability and reliability of the equipment during long-term high-load operation.

[0117] In other examples, the snap-fit ​​structure can be replaced with a clamp, elastic rope, or other winding connection method, or other detachable connection methods such as screws or pins can be used, depending on the specific needs.

[0118] Furthermore, a buffer elastic element 110 is provided on the power distribution function module 100 near the busbar assembly 300. One end of the buffer elastic element 110 can be fixedly connected to the power distribution function module 100, and the other end is a cantilever end that can abut against the insulating protective sleeve 320 in the busbar assembly 300. After the power distribution function module 100 is installed in conjunction with the two drive modules, the buffer elastic element 110 can be used to maintain the stability of the installation. The insulating protective sleeve 320 has clearance space to avoid affecting the contact between the busbar body 310 and the power take-up terminal 210.

[0119] After the power distribution module 100 and the bus assembly 300 are installed and connected, the cantilever end of the buffer elastic element 110 will continuously apply a stable elastic pressure to the insulating protective sleeve 320 of the bus assembly 300. The elastic force of the buffer elastic element 110 will not be too large, which can ensure a reliable electrical connection between the power distribution module 100 and the bus assembly 300, avoiding poor contact caused by vibration or external impact, while also preventing excessive compression of the bus assembly 300 and affecting its normal operation.

[0120] In some examples, the snap-fit ​​assembly 400 on the power module 200 includes a first snap 410, a second snap 420, a transmission mechanism 430, and a control element 440.

[0121] The first latch 410 is set and latched on the first side of the bus assembly 300, the second latch 420 is set and latched on the second side of the bus assembly 300, the transmission end of the transmission mechanism 430 is connected to one of the first latch 410 or the second latch 420, and the drive end of the transmission mechanism 430 is connected to the control member 440, which is at least partially located on the outer periphery of the power extraction module 200.

[0122] The busbar assembly 300 has matching slot structures 321 on both sides.

[0123] When the trigger control element 440 is activated, at least one of the first latch 410 or the second latch 420 is released from engagement by the transmission mechanism 430.

[0124] The aforementioned snap-fit ​​assembly 400 enhances the convenience and flexibility of installing and disassembling the split-type terminal busbar distribution unit. In practice, the operator only needs to trigger the control element 440 located on the outer periphery of the power take-up module 200, which, via the transmission mechanism 430, will cause at least one of the first snap-fit ​​410 or the second snap-fit ​​420 to disengage from the busbar assembly 300. This design avoids the cumbersome process of simultaneously operating multiple snap-fits or using complex tools required in traditional connection methods, greatly improving operational efficiency.

[0125] The first latch 410 and the second latch 420 are respectively located on both sides of the busbar assembly 300 and are interconnected through the transmission mechanism 430, ensuring the stability and reliability of the latching connection. When the latches engage with the latching slots 321 on both sides of the busbar assembly 300, a stable connection is formed, effectively preventing the power extraction module 200 from loosening or falling off due to vibration or external force during operation. This double-sided latching design also enhances the electrical connection performance between the power extraction module 200 and the busbar assembly 300, reduces contact resistance, and improves the efficiency of power transmission.

[0126] The control element 440 also improves the safety and convenience of operation. By placing the control element 440 on the outer periphery of the power supply module 200, operators do not need to directly contact live parts when triggering the control element 440, reducing the risk of electric shock. Furthermore, the triggering method of the control element 440 can be diversified according to actual needs, such as button-type or toggle-type, to meet the usage habits and operating environments of different users.

[0127] In scenarios requiring high installation precision, the design of this snap-fit ​​assembly 400 also enables precise docking between the power supply module 200 and the busbar assembly 300. By optimizing the shape and size of the snap-fit ​​and slot, as well as the transmission precision of the transmission mechanism 430, it can be ensured that the power supply module 200 can accurately snap into the corresponding position of the busbar assembly 300 during installation, avoiding electrical connection problems or mechanical damage caused by installation deviations.

[0128] When the power supply module 200 needs to be replaced or repaired, simply trigger the control component 440 again to release the latch from the busbar assembly 300, and the power supply module 200 can be easily removed from the busbar assembly 300. This convenient disassembly method not only reduces maintenance time and workload, but also lowers the risk of damage to the busbar assembly 300 and other components caused by maintenance operations, thereby improving the maintainability and service life of the entire power distribution system.

[0129] It should be noted that in actual operation, the power supply module 200 can be first snapped into the bus assembly 300 in the predetermined direction. At this time, the power supply module 200 and the bus assembly 300 can slide relative to each other. Then, the power supply module 200 can be connected to the power distribution function module 100 by sliding. Specifically, the power connection terminal 220 and the elastic clamp can be effectively plugged in.

[0130] The slot structure 321 can be specifically set on the aforementioned insulating protective sleeve 320. Setting the slot structure 321 on the insulating protective sleeve 320 allows for a precise and secure engagement with the adapter component. This setup utilizes the structural space of the insulating protective sleeve 320 itself, eliminating the need for an additional independent slot structure 321. While ensuring that the insulation protection performance is not compromised, it simplifies the overall assembly process and improves the reliability and efficiency of the connection between components. The specific dimensions, quantity, and distribution of the slots can be customized according to the structural parameters of the actual adapter component, ensuring structural stability and safety after connection, while also facilitating subsequent disassembly and maintenance.

[0131] The transmission mechanism 430 can be a linkage mechanism, a gear and rack mechanism, a worm gear mechanism, a cam mechanism, or other transmission mechanisms 430. Different transmission mechanisms 430 have their own unique characteristics and applicable scenarios.

[0132] The linkage mechanism has a simple structure and can achieve relatively flexible motion conversion through the connection and motion transmission of the links. It is widely used in power modules 200 and snap-fit ​​components 400 where the motion trajectory requirement is not particularly precise but a large transmission stroke is required. Its cost is low and its manufacturing and maintenance are relatively easy, but it may generate some impact and vibration during operation.

[0133] The rack and pinion mechanism converts the rotational motion of the gear into the linear motion of the rack, or vice versa. It offers high transmission precision, accurately controlling the position and speed of the latch, making it suitable for split-type terminal busbar distribution units with high installation accuracy requirements. However, the rack and pinion mechanism also requires high manufacturing precision, resulting in relatively high costs, and it generates some noise during operation.

[0134] The worm gear mechanism has a large transmission ratio, enabling significant speed reduction within a limited space. This is advantageous in applications requiring large clamping forces but with limited space, such as the power supply module 200 clamping assembly 400. Furthermore, the worm gear mechanism is self-locking; when transmission stops, the latch remains in its current position and will not move due to external forces, thus improving clamping stability.

[0135] A cam mechanism controls the motion of the follower by using the profile curve of the cam. It can achieve complex motion patterns to meet the needs of different engagement and disengagement actions. In some power supply modules 200 and engagement assemblies 400 that require special motion trajectories, the cam mechanism can demonstrate unique advantages. However, the profile design of the cam mechanism requires precise calculations, and the wear between the cam and the follower is significant, necessitating regular maintenance and replacement.

[0136] Depending on the different usage scenarios and performance requirements, a suitable transmission mechanism 430 can be selected and applied to the power take-up module 200 and the snap-fit ​​assembly 400 to achieve the best installation and disassembly effect, and ensure the normal operation and ease of use of the split-type terminal bus distribution unit.

[0137] In some examples, at least one of the first snap-fit ​​410 and the second snap-fit ​​420 is a double snap-fit ​​structure, and the corresponding side of the bus assembly 300 is provided with two slot structures 321 that are spaced apart. The double snap-fit ​​structure can snap into the two slot structures 321 at the same time.

[0138] This dual-clamping structure further enhances the stability and reliability of the connection between the power extraction module 200 and the busbar assembly 300. In practical applications, the dual-clamping structure simultaneously engages with two spaced-apart slots 321 on the corresponding sides of the busbar assembly 300, creating a double-fixing effect. Even under strong vibrations or external impacts, it effectively prevents the power extraction module 200 from loosening, shifting, or even falling off, greatly ensuring the stability of the electrical connection and guaranteeing continuous and stable power transmission.

[0139] The double-clamping structure disperses the force. When subjected to external force, the force is evenly distributed across the two clamping points, rather than concentrated on a single point. This reduces the risk of damage to a single clamping point due to excessive force, extending the service life of the clamping structure and the entire power supply module 200. For example, in some industrial production environments where equipment operation generates significant vibrations, this double-clamping structure can effectively adapt to such harsh working conditions, ensuring a reliable connection between the power supply module 200 and the busbar assembly 300.

[0140] Although the double-clamping structure adds a clamping step during installation, the two clamping slots 321 are spaced apart and relatively fixed in position, allowing operators to operate based on clear positional references, which actually helps improve installation accuracy. Furthermore, once installed correctly, the robust connection provided by the double-clamping structure reduces subsequent adjustments and maintenance work due to connection problems, improving the efficiency of the entire power distribution system installation and operation.

[0141] Furthermore, the double-clamping structure design also offers a degree of tolerance. During manufacturing, if dimensional errors exist, the double-clamping structure can compensate for these errors to some extent, still achieving reliable clamping. This makes it easier to ensure product quality, reduces the product defect rate due to dimensional deviations, and improves production efficiency and product consistency. Simultaneously, this design also facilitates subsequent maintenance and upgrades. When replacing the power module 200 or busbar assembly 300, the double-clamping structure can better adapt to minor differences that may exist between different batches of products, ensuring that the newly replaced components can be smoothly installed and operate stably.

[0142] Furthermore, at least one of the power distribution module 100 and power extraction module 200 described above is provided with a status indicator light to display the working status of the corresponding module.

[0143] Status indicator lights can display different colors or flashing frequencies, allowing operators to intuitively and quickly understand the module's current operating status without the need for complex testing. For example, a solid green indicator light may indicate that the module is operating normally. A flashing red indicator light may mean that the module has malfunctioned or is experiencing an abnormality, requiring timely inspection and repair. This intuitive status display method greatly improves the efficiency of troubleshooting and reduces equipment damage or power outages caused by delayed fault detection.

[0144] Status indicator lights can also display different statuses depending on the operating mode. In some split-type terminal busbar distribution units that require multiple operating modes, such as energy-saving mode and full-load mode, status indicator lights can use different light combinations to distinguish the current operating mode, facilitating management and control by operators. For example, in energy-saving mode, the indicator light may be solid blue. In full-load mode, the indicator light will be solid yellow. In this way, operators can adjust the module's operating mode in a timely manner according to actual needs to achieve optimal energy efficiency and equipment performance.

[0145] Furthermore, status indicator lights can be integrated with other monitoring systems to achieve remote monitoring and automated management. By transmitting the signals from the status indicator lights to the monitoring center, managers can monitor the working status of each module in real time, promptly identify potential problems, and take appropriate measures. For example, when a module's status indicator light shows an abnormality, the monitoring system can automatically issue an alarm to notify relevant personnel for handling. This remote monitoring and automated management approach not only improves management efficiency but also reduces the cost and risk of manual inspections.

[0146] In locations with high electrical safety requirements, such as hospitals and banks, status indicator lights can also serve as safety warnings. When a module malfunctions or malfunctions, the status indicator light can alert nearby personnel to be cautious, preventing electric shock accidents caused by misoperation. Simultaneously, the status indicator light display can provide maintenance personnel with important reference information, helping them to quickly locate the fault point and improve maintenance efficiency and quality.

[0147] Status indicator lights may include, but are not limited to, power indicator lights, fault indicator lights, and running indicator lights, each distinguished by a different color.

[0148] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
