Detailed Implementation

[0020] The terms "first," "second," and "third," etc., used in this application specification and accompanying drawings are used to distinguish different objects, not to limit a specific order.

[0021] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0022] like Figure 1 As shown in the figure, this application embodiment provides a power rail 1000 for detachably connecting functional modules 2000. Through the power rail 1000, various different functional modules 2000 can be detachably connected, meeting the power distribution and wiring expansion needs from the distribution cabinet, the entire workshop, and even the factory level.

[0023] like Figure 2 As shown, the functional module 2000 includes an air switch 2100, and the power connection rail 1000 includes at least one set of linear units. Each linear unit includes a housing 100, a power connection assembly 200, and a cover plate 300. The housing 100 has a receiving cavity 400 extending along a first direction; the power connection assembly 200 is disposed within the receiving cavity 400 and electrically connected to an external power source; the power connection assembly 200 includes multiple sets of conductive bars 210, which extend along the first direction and are arranged parallel and spaced apart along a second direction. The conductive bars 210 are connected to the housing 100, and the functional module 2000 covers the receiving cavity 400 and is plugged into the conductive bars 210; the cover plate 300 covers the receiving cavity 400 and is detachably connected to the housing 100, and the cover plate 300 is configured to jointly close the receiving cavity 400 along the first direction with the functional module 2000.

[0024] Wherein, the first direction is perpendicular to the second direction, the first direction is the length direction of the shell 100, and the second direction is the width direction of the shell 100.

[0025] The multiple sets of conductive bars 210 of the linear unit are spaced apart, which can effectively avoid the risk of leakage and short circuit between adjacent conductive bars 210, and ensure electrical safety. At the same time, the reserved assembly space facilitates the insertion and alignment of functional modules 2000, and can also optimize heat dissipation, reduce the performance loss caused by power-on heat generation, and improve the stability of power distribution operation.

[0026] In addition, temperature sensors and other sensing structures can be arranged within the accommodating cavity 400 to improve safety performance.

[0027] like Figures 3-7 As shown, in one embodiment, the conductive busbar 210 of the power rail 1000 and the functional module 2000 adopt a plug-in connection structure. When replacing or adding / removing the functional module 2000, there is no need to rewire; adjustments can be made simply by plugging and unplugging, making maintenance and expansion more convenient. The detachable connection structure between the cover plate 300 and the housing 100 also facilitates opening the cover plate 300 to inspect the power connection components 200 inside the accommodating cavity 400 when wiring adjustments are needed, making operation convenient. In addition, the cover plate 300 can seal the accommodating cavity 400 when the functional module 2000 is not installed, which can not only avoid the safety hazards caused by exposed conductive busbar 210, but also prevent dust and debris from entering the accommodating cavity 400 and affecting conductivity, thus improving the safety and stability of the power rail 1000.

[0028] Meanwhile, the two adjacent linear units within the accommodating cavity 400 are detachably connected, allowing the overall length and width of the power connection rail 1000 to be spliced ​​and adjusted according to actual wiring and expansion needs, adapting to different installation scenarios.

[0029] In addition, depending on the workpiece and wiring requirements, the two sets of linear units can also be connected at an angle to meet various structural splicing requirements.

[0030] Specifically, such as Figure 3As shown, the conductive busbar 210 includes a connecting part 211 and a mounting part 212. The connecting part 211 is connected to the housing 100; the mounting part 212 is connected to the connecting part 211 and is perpendicular to the connecting part 211. The functional module 2000 is plugged into the mounting part 212. In use, if there is a cover plate 300 at the location where the functional module 2000 needs to be assembled, the cover plate 300 needs to be opened. If there is no cover plate 300, the functional module 2000 can be directly plugged in, and the power terminal of the functional module 2000 can be stably connected to the connecting part 211 without additional wiring operations. Disassembly, assembly, and position adjustment are more convenient and quick. At the same time, the vertically arranged connecting part 211 and mounting part 212 can make full use of the space within the housing 100, reduce the overall volume of the power rail 1000, and make the wiring more compact and neat.

[0031] Alternatively, the connecting part 211 may be made of steel or aluminum.

[0032] Optionally, the connecting part 211 and the mounting part 212 are connected vertically in a T-shape. The connecting part 211 uses a larger surface to connect with the housing 100, which helps to improve the connection strength. The mounting part 212 has a single-arm structure, which facilitates the insertion and mating of the functional module 2000.

[0033] In one embodiment, the mounting part 212 includes a base layer 2121 and a conductive coating layer 2122. The base layer 2121 is connected to the housing 100; the conductive coating layer 2122 covers the base layer 2121 and is made of conductive material. The base layer 2121 can be made of a material with low insulation or low conductivity and high strength. While ensuring the overall structural strength of the conductive busbar 210, electrical connection is achieved only through the outer conductive coating layer 2122. This eliminates the need to use high-cost conductive metals to make the entire conductive busbar 210, thereby reducing raw material costs while meeting conductivity stability requirements and further optimizing the structural design of the power connection rail 1000.

[0034] Optionally, the conductive coating layer 2122 is made of metallic copper. The base layer 2121 is made of any low-cost and high-strength material such as stainless steel, aluminum, or steel.

[0035] Meanwhile, the mounting portion 212 can adjust the conductivity of the connecting portion 211 by controlling the thickness of the conductive coating layer 2122 to meet the requirements of different currents. For example, when applied to devices or functional modules 2000 with high connection currents, the entire mounting portion 212 can be made of a conductive material, such as copper. When used for functional modules 2000 with low connection currents, the mounting portion 212 adopts the structure described above with the conductive coating layer 2122, and the smaller the current requirement, the smaller the thickness of the conductive coating layer 2122 can be.

[0036] In one embodiment, the base layer 2121 is provided with a first groove 2121a and / or a first protrusion 2121b, which extends along a first direction and is located on at least one side of the base layer 2121 along a second direction. The conductive coating layer 2122 is provided with a second groove 2122b and / or a second protrusion 2122a corresponding to the first groove 2121a and the first protrusion 2121b. The second groove 2122b engages with the first protrusion 2121a, and the second protrusion 2122a engages with the first groove 2121a. This groove-protrusion engagement structure increases the contact area between the base layer 2121 and the conductive coating layer 2122, improves the bonding strength between them, prevents the conductive coating layer 2122 from detaching from the base layer 2121 during long-term use, ensures the structural stability and conductive reliability of the conductive busbar 210, and further extends the service life of the power connection rail.

[0037] In one embodiment, the base layer 2121 is made of steel or aluminum, and the conductive coating layer 2122 is made of copper. Figure 4 As shown, the base layer 2121 has a first groove 2121a on each side, and the conductive coating layer 2122 has a first protrusion 2122b corresponding to the first groove 2121a. The first groove 2121a and the first protrusion 2122b cooperate with each other. Due to thermal expansion and contraction, the copper conductive coating layer 2122 will slide relative to the base layer 2121 along the second direction during the process of temperature rise or fall. The cooperation structure of the groove and the protrusion can always ensure that the conductive coating layer 2122 is tightly attached to the base layer 2121 and will not delaminate or loosen due to the cyclic effect of thermal expansion and contraction. This further improves the environmental adaptability of the overall structure of the conductive busbar 210 and ensures the stability of the conductive connection under different temperature conditions.

[0038] like Figure 5 As shown, in another embodiment, the outer side of the base layer 2121 may include at least one of the following: multiple first grooves 2121a arranged adjacently or at intervals; multiple first protrusions 2122b arranged adjacently or at intervals; or alternating arrangement of first grooves 2121a and first protrusions 2122b. Second protrusions 2122a and second grooves 2122b are arranged corresponding to the first grooves 2121a and first protrusions 2122b, forming a snap-fit ​​limiting structure. This structure can maintain a snap-fit ​​limiting state even when the conductive coating layer 2122 undergoes relative expansion and contraction along the second direction. This does not hinder the deformation displacement of the conductive coating layer 2122 due to thermal expansion and contraction, and continuously restricts the relative separation of the conductive coating layer 2122 from the base layer 2121 in the direction perpendicular to the second direction. This further simplifies the processing technology for the mating of the base layer 2121 and the conductive coating layer 2122, while still ensuring the overall reliability of the structure and avoiding delamination and loosening problems.

[0039] In another embodiment, the base layer 2121 has a second protrusion 2121b on at least one of its two sides perpendicular to the first direction, and the conductive coating layer 2122 has a second groove 2122b corresponding to the second protrusion 2121b, with the second protrusion 2121b and the second groove 2122b engaging with each other. In practical applications, such as... Figure 5 As shown, the base layer 2121 has three sets of second protrusions 2121b on each side perpendicular to the first direction. Each side can have one or more second protrusions 2121b. When there are multiple second protrusions 2121b, they are arranged parallel to each other in the direction away from the connecting part 211. The second protrusions 2121b and the second grooves 2122b engage with each other, thereby limiting the direction of separation of the conductive coating layer 2122. This increases the limiting strength between the base layer 2121 and the conductive coating layer 2122. When the conductive coating layer 2122 slides relative to each other in the second direction, it can always maintain the engaging and limiting state. This does not hinder the deformation displacement of the conductive coating layer 2122 caused by thermal expansion and contraction, and can continuously limit the relative separation of the conductive coating layer 2122 and the base layer 2121 in the direction perpendicular to the second direction. This further simplifies the processing technology of the base layer 2121 and the conductive coating layer 2122, while still ensuring the overall reliability of the structure and avoiding the problem of delamination and loosening.

[0040] In one embodiment, such as Figure 2 and Figure 6 , Figure 7 As shown, the housing 100 includes a bottom 110 and two sets of side plates 120. A conductive bar 210 is connected to the side of the bottom 110 facing the accommodating cavity 400; one set of side plates 120 is connected to the side of the bottom 110 along a second direction, and the other set of side plates 120 is connected to the other side of the bottom 110 along the second direction. The side plates 120 are provided with mounting holes 130 for inserting connectors 140 to connect the side plates 120 and the functional module 2000, the side plates 120 and the cover plate 300.

[0041] In one embodiment, the accommodating cavity 400 is formed by a bottom 110, two sets of side plates 120, and a cover plate 300. The conductive busbar 210 is housed inside the accommodating cavity 400 and, through the mounting holes 130 on the side plates 120 and the connectors 140, completes the assembly and fixation between the power connection rail 1000, the functional module 2000, and the cover plate 300. This not only provides a closed protection for the conductive busbar 210 inside the accommodating cavity 400, preventing the conductive structure from being exposed and causing safety hazards, but also makes the assembly of the power connection rail 1000 with other functional modules more convenient, improving the overall assembly efficiency of the power distribution device. As the core conductive component of the power connection rail 1000, the conductive busbar 210, after being stably housed in the accommodating cavity 400, can work with the conductive coating layer 2122 and the base layer 2121 to continuously maintain the positional stability of the conductive structure, ensuring the long-term stable conductivity of the power connection rail.

[0042] This application embodiment also provides a power distribution device, including the aforementioned power-connecting rail 1000 and a plurality of functional modules 2000 detachably connected to the power-connecting rail 1000. The functional modules 2000 are plugged into the power-connecting rail 1000 and include at least one of an air switch 2100, an airflow drive module, a main input module, and a parallel module for connecting multiple power-connecting rails 1000 in parallel. The functional modules 2000 are arranged continuously or at intervals along a first direction.

[0043] For example, such as Figure 1 As shown, the airflow drive module is a fan 2200, located at one end of the power rail 1000. When the fan is working, it drives airflow to cool the accommodating cavity 400, preventing risks caused by overheating. When a temperature sensor is installed inside the accommodating cavity 400, the fan 2200 can be connected to the temperature sensor signal. When the temperature sensor detects a temperature higher than a preset temperature, the fan 2200 starts, driving airflow within the accommodating cavity 400 of the linear unit to achieve cooling. Controlling the fan 2200's start and stop by connecting it to a temperature sensor helps reduce energy consumption.

[0044] The main input module is the incoming line module for connecting to external mains power or industrial power supply. It can be equipped with incoming line terminals, an incoming line protective housing, and an incoming line busbar. As the main power input terminal of the entire power connection rail 1000, it realizes centralized power introduction and distribution. The main input module is the power input terminal of the entire power distribution device. It can centrally collect the power connected to the external power grid and then distribute the power to each circuit breaker through the power connection rail 1000. This realizes centralized power input and branched output, which facilitates unified management of the power distribution path by users and also makes it easy to add or remove circuit breakers as needed to flexibly adjust the power distribution capacity.

[0045] Among them, the parallel module for connecting multiple power rails 1000 in parallel connects to the conductive busbars 210 of adjacent power rails 1000 through conductive plug terminals, so as to realize the electrical parallel conduction of multiple power rails 1000; it can expand the power supply circuit capacity, balance the load current, unify the network power distribution, and at the same time retain the independent disassembly and maintenance of a single power rail 1000, and improve the power supply expansion capacity and the regularity of the line layout.

[0046] When each functional module is assembled on the power connection rail 1000, it only needs to be plugged into the power connection rail 1000 to complete the wiring and conduction. There is no need to perform additional exposed wiring operations on the conductive structure. While ensuring the accuracy and safety of wiring, it further improves the overall assembly and maintenance efficiency of the power distribution device.

[0047] In one embodiment, such as Figure 8 As shown, taking the air switch 2100 as an example, functional module 2000 includes a functional component 2002 and a plug-in component 2001 connected to the functional component 2002. Multiple sets of plug-in components 2001 are arranged at intervals along the second direction, and each set of plug-in components 2001 is plugged into multiple sets of conductive busbars 210 in a one-to-one correspondence. Each set of connecting components 2000 corresponds to one set of conductive busbars 210, enabling the separate supply of power to different functional modules 2000, avoiding mutual interference between different lines, and improving the stability of the power distribution device. When one set of connecting components 200 or its corresponding conductive busbar 210 malfunctions, only the corresponding component needs to be checked and replaced individually, without disassembling the entire power distribution device, further reducing the difficulty and cost of maintenance and repair.

[0048] like Figures 9-10 As shown, specifically, the functional component 2002 can be two-phase, three-phase, or four-phase. Corresponding to the functional component 2002, each item is connected to a set of plug-in components 2001 for plugging into the corresponding conductive busbar 210 on the power rail 1000. Since the conductive busbars 210 are arranged parallel and spaced apart along the second direction, multiple sets of plug-in components 2001 are arranged spaced apart along the second direction in a layout that adapts to the conductive busbars 210.

[0049] In use, the functional component 2002 is provided with a power terminal, which can be located on one side or in the middle. The plug-in component 2001 is connected to the power terminal of the corresponding phase and then set in accordance with the position of the corresponding conductive bus 210.

[0050] The 2000 functional module can adapt to different power supply specifications such as two-phase, three-phase, and four-phase. The plug-in components are arranged according to phase matching, and the conductive bars 210 arranged at intervals are accurately matched to complete the docking, with a wide range of compatibility. The position of the power connection terminal is flexibly adjustable, which can adapt to various wiring layouts. The phases are connected independently without interference, ensuring the stability of multi-phase circuit power supply and adapting to the needs of different power distribution conditions.

[0051] In use, simply plugging the connector 2001 at the bottom of the air switch 2100 into the mounting part 212 of the conductor bar 210 is sufficient to establish circuit continuity, which is very convenient. Compared to traditional wiring methods, there is no need for additional wire stripping and twisting to complete the wiring, greatly simplifying the installation steps of the air switch 2100. Installers do not need professional electrical knowledge to complete the operation, reducing the installation threshold and labor costs. At the same time, the air switch 2100 can provide overload and short-circuit protection for its branch circuit. When a fault occurs in the corresponding branch circuit, the air switch 2100 will automatically disconnect, without affecting the normal operation of other branches of the power distribution device, further improving the safety of the power distribution device.

[0052] In one embodiment, each set of plug-in components 2001 includes at least one set of clamps 2011.

[0053] like Figure 7 , Figure 9 As shown, the clamping component 2011 includes a connecting section 2011a and two sets of clamping sections 2011b. The connecting section 2011a is connected to the functional module 2000; the two sets of clamping sections 2011b are connected to both ends of the connecting section 2011a, and a clamping opening is provided between the two sets of clamping sections 2011b. The clamping opening can elastically open under external force, and the two sets of clamping sections 2011b are used to clamp the conductive busbar 210 for conductive connection. This clamping component 2011 clamps the conductive busbar 210 using the elastically opening and closing clamping opening, enabling rapid conductive connection between the functional module 2000 and the conductive busbar 210, facilitating convenient assembly and disassembly. The double-sided clamping structure provides sufficient contact area, ensuring stable and reliable conductivity. The elastic clamping adapts to assembly tolerances, reducing the likelihood of loosening and power failure. Furthermore, the structure is simple and compact, suitable for the limited installation space inside the power connection rail 1000.

[0054] like Figure 10 and Figure 11 As shown, in one embodiment, when each set of plug-in components 2001 includes multiple sets of clamping members 2011, the multiple sets of clamping members 2011 are spaced apart along the first direction, thereby matching different current requirements using the number of clamping members 2011. When the current is large, multiple sets of clamping members 2011 connected to each phase can be set along the first direction; when the current is small, only one set of clamping members 2011 connected to each phase can be set. In this embodiment, the number of clamping members 2011 in the same phase can be flexibly increased or decreased according to the power supply current. Under high current conditions, adding clamping members 2011 can increase the total conductive contact area, reduce line current carrying loss and heat generation risk; under low current conditions, simplified components can meet the power supply requirements, with strong structural adaptability, taking into account both power supply safety and material economy.

[0055] like Figure 11As shown, the air switch 2100 is three-phase and has three-phase terminals along the first direction. One of the terminals is connected to three sets of clamping members 2011 through a conductive sheet, and adjacent phases are isolated by insulating material.

[0056] When the current is large, for a certain phase (leading out from the functional component 2002), multiple clamping members 2011 can be set in the first direction to clamp the mounting part 212 of the conductive bus 210, so as to realize the electrical connection with the connection part 211. Since the multiple clamping members 2011 are electrically connected to each other, the current carrying capacity of that phase can be increased. When the current is small, only one or two sets of clamping members 2011 need to be set in the corresponding phase to meet the conductivity requirements. No additional structure is required. The number of clamping members 2011 can be flexibly adjusted according to the actual current usage requirements. While meeting the conductivity requirements, structural redundancy is avoided, and the processing and manufacturing cost of the device is reduced.

[0057] In one embodiment, the clamping member 2011 further includes two sets of guide segments 2011c. Each set of guide segments 2011c is connected to one end of each set of clamping segments 2011b away from the connecting segment 2011a. The distance between the two sets of guide segments 2011c gradually increases along the direction away from the clamping segment 2011b. This structure guides the insertion of the conductive busbar 210, allowing it to slide more smoothly into the clamping opening along the guide segments 2011c, reducing alignment difficulties during assembly and improving assembly efficiency. Simultaneously, the flared design of the guide segments 2011c prevents scratching the surface of the conductive busbar 210 during insertion, ensuring the stability of the conductive connection.

[0058] like Figure 11 As shown, in one embodiment, the width of the clamping member 2011 along the first direction is selectively set according to the current of the functional component. When the operating current of the functional component of the power distribution device is large, the width of the clamping member 2011 along the first direction can be increased to increase the contact area between the clamping member 2011 and the conductive busbar 210, reduce the contact resistance, meet the conductivity requirements of large current, and avoid local overheating that could cause safety hazards. When the operating current of the functional component is small, the width of the clamping member 2011 along the first direction can be reduced accordingly to reduce material usage, control the overall production cost and volume of the power connection rail 1000, adapt to the usage requirements of different current specifications, and improve the adaptability flexibility of the power connection rail 1000.

[0059] like Figures 8-11As shown, the air switch 2100 is three-phase. Therefore, the air switch 2100 has three sets of clamping members 2011 along the first direction and three sets of clamping members 2011 along the second direction. Correspondingly, the housing 100 has a mounting part 212 for the conductive bus 210 that plugs into the clamping members 2011. When the air switch 2100 is connected to the power connection rail 1000, each clamping member 2011 is inserted into the mounting part 212 on the housing 100, forming a stable clamping contact with the corresponding conductive bus 210. The power connection of the air switch 2100 can be completed without additional tightening of bolts or other fixing operations, simplifying the installation steps, shortening the disassembly and assembly time, and improving the convenience of assembling and maintaining the power distribution device. At the same time, the multiple sets of clamping members 2011 are arranged correspondingly along the first and second directions, which can ensure the reliability of the conductive connection from multiple directions simultaneously, avoiding the problem of poor contact after the air switch 2100 is shaken or displaced by external forces, and improving the overall stability of the power distribution device.

[0060] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
