Description
TECHNICAL FIELD

[0002] At present, the maximum rated current of the mainstream brand of miniature circuit breakers on the market is difficult to meet the demand of high-power scenarios due to the volume and breaking capacity.

In addition, the design of the conventional power distribution unit (PDU) needs to adapt to the miniature circuit breaker as a protection device, and the single-channel switch capacity of the PDU is usually only half of the rated value of the miniature circuit breaker, which makes it difficult for a single PDU to meet the demand of high-power density cabinets. If the cross-sectional area of the copper bar is increased to improve its carrying capacity, it will waste materials and increase costs. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION
[0021] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
[0022] It should be noted that the technical terms or scientific terms used in the present application should be understood as their general meanings understood by those skilled in the art unless otherwise specified.
[0023] It should be noted that in the description of the present application, the terms "upper", "lower", and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be understood as limiting the present application; the terms "connection", "mounting", "fixing" and the like should be understood broadly, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.
[0024] In the description of the present application, the terms "one embodiment", "some embodiments", "a specific embodiment", and the like mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0025] The inventors found that the capacity of a single power distribution unit (PDU) used in a cabinet is limited by the internal copper bars. One possible improvement method is to increase the cross-sectional area of the copper bars (metallic conductors used as power transmission paths) inside the PDU to increase their current carrying capacity. Although this method can increase the current carrying capacity to some extent, it also brings new problems: first, the increased copper bars can cause poor heat dissipation performance, affecting the stability and safety of the entire system; second, it also causes waste of materials and increases costs.
[0026] Reference is made to the accompanying drawings Figure 1 - the accompanying drawings Figure 2 Embodiment one of the present application proposes a conductive part 1, comprising: a first conductive part 11, having a first end 111 and a second end 112 oppositely arranged along its extension direction; a second conductive part 12, having a third end 121 and a fourth end 122 oppositely arranged along its extension direction; wherein the third end 121 and the first end 111 are located on the same side to form a current input end 2 together, and the fourth end 122 and the second end 112 are on the same side to form a load end 3 together, and the cross-sectional area of the current input end 2 is greater than that of the load end 3.
[0027] In one possible case, the first conductive part 11 and the second conductive part 12 can be made of high-conductivity copper material to provide a basic current transmission path. The first conductive part 11 has a first end 111 and a second end 112 oppositely arranged along its extension direction, and the second conductive part 12 has a third end 121 and a fourth end 122 oppositely arranged along its extension direction. The first conductive part 11 can maintain a constant cross-sectional area, and the second conductive part 12 is superimposed on the first conductive part 11, and the cross-sectional area of the second conductive part 12 gradually decreases from its third end 121 to its fourth end 122, forming a larger total cross-sectional area at the current input end 2 and a smaller total cross-sectional area at the load end 3. Alternatively, the first conductive part 11 and the second conductive part 12 are both copper bars with a cross-sectional area decreasing from the current input end 2 to the load end 3. By superimposing the second conductive part 12 on the first conductive part 11, a composite structure is formed, so that the overall conductive part 1 has a larger total cross-sectional area at the current input end 2 and a smaller total cross-sectional area at the load end 3. Among them, the current input end 2 refers to the starting point of the power entering the conductive part 1, that is, the position of the power connection, and the load end 3 refers to the part of the circuit farthest from the current input end 2, which is located at the terminal of the power distribution path. That is, the current input end 2 is the place where the electric energy enters and starts to be distributed, and the load end 3 is the last point on the electric energy distribution path, which is also the load connection point farthest from the current input end 2.
[0028] The current input 2 needs to have sufficient capacity to carry the total current required by all the devices connected subsequently. As the distance from the input increases, the copper bars behind each socket only need to supply the remaining load, so the total amount of current flowing through this section decreases. The superposition of the first and second conductive sections 11, 12 at the current input 2 provides a greater total cross-sectional area, enhancing the current carrying capacity at this point and ensuring that the requirements of high power density are met. As the load end 3 is further away from the current input 2 and only needs to carry the remaining current, these locations use conductors with a smaller cross-sectional area, both saving material and ensuring that the performance of the electrical conductor 1 is not affected, optimising the material usage efficiency of the entire electrical conductor 1 while maintaining the necessary electrical performance.
[0029] In some alternative embodiments of the first aspect of the application, the first and second conductive sections 11, 12 are formed as a single conductor by an integrated manufacturing process.
[0030] In one possible case, the first and second conductive sections 11, 12 are formed as a single conductor by an integrated manufacturing process. Rather than being manufactured separately and then assembled together, the two conductive sections are formed simultaneously as a whole during the manufacturing process, simplifying the manufacturing process, reducing assembly steps and eliminating the contact resistance problems associated with discrete joints, providing a more reliable electrical connection and mechanical strength.
[0031] In some embodiments, the cross-sectional area of the single conductor decreases along the direction from the current input 2 to the load end 3.
[0032] In one possible case, as shown in Figure 1 The first conductive section 11 can be a conductor with a large initial cross-sectional area, which gradually decreases in width or thickness as the distance increases. The second conductive section 12 is integrated with the first conductive section 11, but its cross-sectional shape is wider or thicker near the current input 2 and gradually narrows or thins along the length. Finally, the two sections together form a continuously changing cross-sectional area; or the first conductive section 11 includes multiple segments, each with a different fixed cross-sectional area, with the part closest to the current input 2 having the largest cross-sectional area, and each subsequent segment being slightly smaller than the previous one until the smallest cross-sectional area is reached. The second conductive section 12 can also include multiple segments, each matching the corresponding segment of the first conductive section 11, and the first and second conductive sections 11, 12 can be connected by welding, crimping or other connection methods.
[0033] The single conductor formed by the first conductive part 11 and the second conductive part 12 has a cross-sectional area that decreases from the current input end 2 to the load end 3. This structure is adapted to the feature that the current gradually decreases from the current input end 2 to the load end 3. The total cross-sectional area of the current input end 2 is the largest, which can withstand a larger current input. As the distance increases, the cross-sectional area of each conductive part gradually decreases, and finally reaches the minimum value at the load end 3. The gradually changing cross-sectional area not only helps to uniformly distribute the current, but also improves the overall heat dissipation effect, because the part with a larger cross-sectional area can better dissipate heat and prevent overheating. The single conductor increases its current-carrying capacity by increasing its cross-sectional area, and saves materials by setting its cross-sectional area in a decreasing form.
[0034] In some embodiments, the thickness of the first conductive part 11 along the second direction B is equal to the thickness of the second conductive part 12 along the second direction B, and the height of the current input end 2 along the first direction A is greater than the height of the load end 3 along the first direction A; wherein the first direction A is perpendicular to the extension direction of the first conductive part 11, and the second direction B is perpendicular to the first direction A and the extension direction of the first conductive part 11.
[0035] In a possible case, the thickness of the first conductive part 11 and the second conductive part 12 in the second direction B is the same, which ensures the uniformity and stability of the overall structure, simplifies the manufacturing process, and helps to maintain consistent mechanical strength and electrical performance. Since the current input end 2 needs to carry the total current required by all subsequent devices, it is set to have a larger height along the first direction A. This increases its cross-sectional area, improves current-carrying capacity, and also helps to reduce resistance and heat generation. As the current is distributed to each subsequent load, the remaining current is smaller when it reaches the load end 3, so the height here can be set smaller. In this way, not only materials are saved, but also weight is reduced, while the electrical performance of the conductive part 1 is not affected.
[0036] In some embodiments, the side of the second conductive part 12 opposite to the first conductive part 11 along the first direction A is a bevel.
[0037] In a possible case, as Figure 1As shown, in order to prevent the tip portion from appearing on the side of the second conductive part 12 opposite to the first conductive part 11, thereby avoiding the generation of electrical phenomena such as arc, the side of the second conductive part 12 opposite to the first conductive part 11 can be designed as a bevel along the first direction A (i.e. perpendicular to the extension direction of the first conductive part 11). The side of the second conductive part 12 opposite to the first conductive part 11 can be a smooth transition bevel, so that the surface has no abrupt tip portion, so that the entire single conductor forms a right trapezoidal structure in the cross section of the second direction B. The angle of the bevel can be adjusted according to the specific design requirements and application scenarios to ensure the best electrical performance. The height of the current input end 2 and the load end 3 of the single conductor which forms a right trapezoidal single conductor in the cross section of the second direction B in the first direction A can be set according to actual needs, such as: when the current input is 32A, the cross-sectional area of the current input end 2 can be greater than or equal to 6mm 2 , the cross-sectional area of the load end 3 can be greater than or equal to 3.2mm 2 ; when the current input is 63A, the cross-sectional area of the current input end 2 can be greater than or equal to 16mm 2 , the cross-sectional area of the load end 3 can be greater than or equal to 8mm 2 ; when the current input is 80A, the cross-sectional area of the current input end 2 can be greater than or equal to 20mm 2 , the cross-sectional area of the load end 3 can be greater than or equal to 10mm 2 ; when the current input is 100A, the cross-sectional area of the current input end 2 can be greater than or equal to 24mm 2 , the cross-sectional area of the load end 3 can be greater than or equal to 12mm 2 ; when the current input is 125A, the cross-sectional area of the current input end 2 can be greater than or equal to 30mm 2 , the cross-sectional area of the load end 3 can be greater than or equal to 12mm 2 , etc. In addition to preventing arc, the bevel can also help improve the distribution of current, especially in the transition area between different cross-sectional areas. Smooth transition helps to reduce the impact of resistance change, further improving the stability and efficiency of the system.
[0038] In some embodiments, the side of the second conductive part 12 opposite to the first conductive part 11 along the first direction A includes a plurality of stepped surfaces 4, and the distance between the plurality of stepped surfaces 4 and the first conductive part 11 decreases along the extension direction of the second conductive part 12.
[0039] In one possible case, as Figure 2As shown, the back side of the second conductive part 12 (i.e., the side opposite to the first conductive part 11) may include multiple stepped surfaces 4. The distance between the multiple stepped surfaces 4 and the first conductive part 11 gradually decreases along the extension direction of the second conductive part 12, forming a gradual approach trend, that is, the cross-sectional area of the single conductor composed of the first conductive part 11 and the second conductive part 12 decreases from the current input end 2 to the load end 3. Depending on the current requirements and space constraints in the actual application, different numbers and sizes of stepped surfaces 4 can be designed. For example, in some application scenarios, 3 to 5 stepped surfaces 4 can be set, and the height difference between each stepped surface 4 can be adjusted according to the current attenuation. By adjusting the height and width of each step, the current carrying capacity of different parts can be controlled more flexibly.
[0040] In some embodiments, the side of the first conductive portion 11 opposite to the second conductive portion 12 along the first direction A is a plane; wherein, the first direction A is perpendicular to the extending direction of the first conductive portion 11.
[0041] In one possible case, such as Figures 1-2 As shown, the opposite sides of the first conductive part 11 and the second conductive part 12 are flat and smooth planes. This flatness makes the connection of the conductive part 1 to other components or modules (such as the output module 18) simpler and more direct. Whether by bolting, welding, or other forms of mechanical connection, the flat surface provides a stable and reliable contact surface, while also reducing alignment problems during assembly, lowering installation difficulty and error rate.
[0042] A second aspect of this application provides a power strip, comprising: a conductive element 1, the conductive element 1 including: a first conductive portion 11 having a first end 111 and a second end 112 disposed opposite to each other along its extension direction; a second conductive portion 12 having a third end 121 and a fourth end 122 disposed opposite to each other along its extension direction; wherein the third end 121 and the first end 111 are located on the same side to jointly form a current input terminal 2, and the fourth end 122 and the second end 112 are on the same side to jointly form a load terminal 3, and the cross-sectional area of the current input terminal 2 is larger than the cross-sectional area of the load terminal 3.
[0043] In one possible case, such as Figures 3-4As shown, the types of the power strip include but are not limited to household power strip, industrial power strip, etc. In the power strip, the current input end 2 needs to have sufficient capacity to carry the total current required by all subsequent connected devices. As the distance from the input end increases, the copper bar behind each socket only needs to supply power to the remaining load, so the total amount of current flowing through this part will gradually decrease. The superposition of the first conductive part 11 and the second conductive part 12 at the current input end 2 provides a larger total cross-sectional area, enhancing the current carrying capacity at this point and ensuring that the demand for high power density is met. Since the load end 3 is far from the current input end 2 and only needs to carry the remaining current, these locations can use conductors with smaller cross-sectional areas, both saving materials and ensuring that the performance of the power strip is not affected. This design optimizes the material usage efficiency of the entire power strip while maintaining the necessary electrical performance.
[0044] In some alternative embodiments of the second aspect of the present application, the number of conductive parts 1 is 3, corresponding to the neutral line, the live line and the protective line. Among them, the cross-sectional area of the current input end 2 of the protective line is smaller than that of the current input end 2 of the live line, and the cross-sectional area of the load end 3 of the protective line is smaller than that of the load end 3 of the live line.
[0045] In one possible case, in some alternative embodiments of the second aspect of the present application, the number of conductive parts 1 in the power strip is 3, corresponding to the neutral line, the live line and the protective line. This configuration meets the design requirements of the standard three-phase power supply system, ensuring electrical safety and efficiency. The neutral line provides a return path so that current can flow back to the power source. The live line directly outputs current from the power source and is the main path for current to enter the load. In order to carry larger current, especially in high power applications, the current input end 2 and the load end 3 of the live line need to have larger cross-sectional areas to ensure low resistance and high efficiency. As a safety measure, the protective line is mainly used for grounding to prevent electric shock hazards caused by live equipment housings. The main role of the protective line is to provide a low-impedance path for the rapid release of fault current, rather than carrying large current for a long time. Therefore, in this alternative embodiment, the cross-sectional area of the current input end 2 and the load end 3 of the protective line can be smaller than that of the corresponding parts of the live line. For example, when the input current is 125A, the cross-sectional area of the current input end 2 of the neutral line and the live line can be 12mm 2 , the cross-sectional area of the load end 3 can be 30mm 2 , the cross-sectional area of the current input end 2 of the protective line can be 12mm 2 , and the cross-sectional area of the load end 3 can be 6mm 2 . In alternative embodiments of the second aspect of the present application, by setting different cross-sectional areas for the neutral line, the live line and the protective line, the basic requirements of electrical safety are met, and efficient power transmission and reasonable cost control are achieved.
[0046] In some embodiments, the power strip further comprises: a plurality of output modules 18, which are arranged at intervals along the extension direction of the first conductive part 11, and each output module 18 has an output part 181 and a connecting part 182; wherein the connecting part 182 is connected to the side of the first conductive part 11 away from the second conductive part 12, and the output part 181 is used to connect external devices.
[0047] In a possible case, as shown in Figures 3-4 The output part 181 is used to directly connect external devices, such as household appliances, office equipment or other electronic devices. The output part 181 is usually equipped with standard socket holes, which can be two-hole or three-hole to adapt to different plug types. The output part 181 can be located at the front end of the output module 18, which is convenient for users to insert various electrical equipment. The connecting part 182 is used to physically connect the output module 18 with the first conductive part 11 and realize electrical communication. Through this connection mode, the current can be transmitted from the first conductive part 11 to each output module 18, and then supplied to external devices by the output module 18. The connecting part 182 is connected to the side of the first conductive part 11 away from the second conductive part 12. A plurality of output modules 18 are arranged at intervals along the extension direction of the first conductive part 11 or at unequal intervals according to requirements. Such a layout ensures the independence of each output module 18, while also maximizing the use of the space of the power strip. The current first enters the conductive part 1 composed of the first conductive part 11 and the second conductive part 12 from the current input end 2. Since the cross-sectional area of the current input end 2 of the conductive part 1 is large, it can effectively bear a large current without generating too much heat. As the current flows along the first conductive part 11 to the load end 3, it is transmitted to each output module 18 through the connecting part 182 of each output module 18. Finally, the current is supplied to the external devices connected to the output part 181 through the output part 181. Each output module 18 can work independently, and even if a device fails, it will not affect the normal operation of other devices.
[0048] The shell 8 of the power strip can be made of aluminum alloy material, and the surface is treated by paint spraying. The shell 8 can be divided into a panel and a U-shaped rear cover. The panel can be punched according to the installation requirements, and the rear cover can be combined with the panel by sliding in and fixed by screws. The part of the shell 8 close to the current input end 2 is provided with a wire inlet 17, which can be provided with a rubber ring to provide cable compression and prevent water from entering.
[0049] The power strip can be provided with an upper fixing plate 9 and a lower fixing plate 10, which can be steel plates, and each fixing plate is provided with mounting holes, which can be of any shape, such as circular holes, long oval holes, etc. The power strip can be fixed to the rear of the cabinet by inserting bolts into the mounting holes. The power strip can be provided with a total input terminal box 13 for connection with external cables, which can be welded or crimped to the conductive part 1 by a flexible wire. In addition, according to different needs of users, a circuit breaker 15 can be provided for connecting or disconnecting the total power supply of the power strip. The internal connecting part 14 of the power strip can be a copper wire or a copper bar, mainly used for lapping, as shown in Figure 3 The total input terminal box 13 and the input end of the circuit breaker 15 can be connected by the connecting part 14, as shown in Figure 3 The lapping wire between the output end of the circuit breaker 15 and the live wire conductive part 1 in the power strip. The power strip can be provided with a surge protection device 16 for preventing voltage surges caused by lightning strikes and the like to protect the safety of the connected equipment.
