While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0023] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0024] As briefly mentioned earlier, existing power distribution equipment has its problems. Specifically, because both the distribution units on the large busbar and the terminal boxes on the small busbar need to be equipped with circuit breakers to ensure circuit safety, the terminal boxes on the small busbar need to install the same circuit breakers as the distribution units on the large busbar. This configuration not only increases the cost of the power distribution equipment but also increases its complexity, especially since installing circuit breakers on the terminal boxes on the small busbar significantly increases costs.

[0025] Secondly, in existing power distribution equipment, the large busbar distribution unit is connected to the terminal box of the small busbar via cables. This connection method presents many inconveniences during actual installation. The length, route, and selection of connection points of the cables all require precise calculation and design, often necessitating significant manpower and time to complete the installation work. On-site cable installation is not only time-consuming, but also further increases labor costs and installation difficulty due to space constraints and electromagnetic interference issues that need to be considered during cable laying.

[0026] Furthermore, the complexity of cable connections makes the maintenance and troubleshooting of power distribution equipment more difficult. When electrical faults occur, fault location and repair require more time, further increasing operating costs.

[0027] To address, or at least partially address, the aforementioned problems or other potential problems of existing power distribution equipment solutions, embodiments of this disclosure provide a solution for a busbar trunking connection device. The connection device includes a first busbar connector coupled to a first busbar. Further, the connection device includes a second busbar connector comprising a connection body and an adjustment assembly. The connection body is coupled to the second busbar. The adjustment assembly is coupled to both the connection body and the first busbar connector and is adapted to adjust the position of the connection body relative to the first busbar connector in a first direction and a second direction other than the first direction, to facilitate connection between the first and second busbars. Further, the connection device includes a flexible connector flexibly connected between the first busbar connector and the connection body to allow the connection body to move relative to the first busbar connector while establishing an electrical connection between the first and second busbars.

[0028] In this way, the connection between the first busbar and the second busbar becomes more convenient and efficient through the first busbar connector and the second busbar connector. The adjustment component can adjust the position of the connection body relative to the first busbar connector in two different directions, so that the docking error in both the horizontal and vertical directions can be effectively compensated during the actual installation process, thereby effectively simplifying the busbar trunking docking process and reducing installation time and labor costs.

[0029] Secondly, the flexible connector enables a reliable electrical connection between the connecting bodies of the first busbar connector and the second busbar connector. The flexible connector not only allows the adjustment assembly to adjust the position of the connecting body relative to the first busbar connector in two different directions, but also effectively distributes the high current from the first busbar to the second busbar, ensuring stable current transmission and improving the reliability and safety of the power distribution equipment.

[0030] The following will combine Figures 1 to 6This document describes the specific structure and operation of a connection device 100 for busbar trunking in power distribution equipment. In embodiments of this disclosure, the connection device 100 generally includes a first busbar connector 110, a second busbar connector 120, and a flexible connector 130. The second busbar connector 120 is adjustable relative to the first busbar connector 110, and the flexible connector 130 is coupled between the first busbar connector 110 and the second busbar connector 120 to accommodate the displacement of the second busbar connector 120. Through the coordinated operation of the first busbar connector 110, the second busbar connector 120, and the flexible connector 130, rapid and precise connection of the busbar trunking can be achieved, while providing flexible adjustment functions to ensure the stability and reliability of current transmission, reducing the cumbersome cable connections and related labor costs of traditional installation methods.

[0031] Specifically, the first busbar connector 110 is used to couple with the first busbar 101 (such as a main busbar). In some embodiments, the first busbar connector 110 is fixedly connected to the connection portion of the first busbar 101 via a pin. The shape and size of the first busbar connector 110 are designed according to different types of main busbars to ensure the firmness and stability of the connection. The first busbar connector 110 also includes a fixing mechanism (such as a bolt or clamping structure) for firmly fixing the first busbar connector 110 to the first busbar 101 to prevent loosening during use and to ensure the reliability of the electrical connection.

[0032] Furthermore, the second busbar connector 120 includes a connecting body 1201 and an adjusting assembly 1202. Specifically, the connecting body 1201 is used to couple with the second busbar 102 (such as a small busbar). For example, the connecting body 1201 is connected to the small busbar 102 via a small busbar connector. Simultaneously, the connecting body 1201 is connected to the adjusting assembly 1202, which adjusts the position of the connecting body 1201 in the first direction A and the second direction B.

[0033] Furthermore, the adjusting component 1202 is connected to the first busbar connector 110 to adjust the position of the connecting body 1201 in two directions. In some embodiments, the adjusting component 1202 includes a horizontal adjusting screw and a vertical adjusting screw, which can be adjusted to precisely adjust the position of the second busbar connector 120 relative to the first busbar connector 110. The adjustment directions include a first direction A (e.g., horizontal) and a different second direction B (e.g., vertical) to ensure that the first busbar 101 and the second busbar 102 can be precisely mated and that no gaps or misalignments occur during the connection process.

[0034] Furthermore, the flexible connector 130 is used to connect the first busbar 101 and the second busbar 102, and can adapt to changes in the relative position between the first busbar connector 110 and the second busbar connector 120. That is, the flexible connector 130 is connected between the connecting body 1201 of the first busbar connector 110 and the second busbar connector 120. This flexible connector 130 can be made of a high-temperature resistant, highly conductive material (such as copper or aluminum alloy), and possesses a certain degree of flexibility and elasticity, allowing it to adapt to deviations or changes in the busbar trunking during installation. The flexible connector 130 can effectively distribute the current from the large busbar to the small busbar, ensuring the uniformity and stability of power transmission.

[0035] In actual installation, the first busbar connector 110 is first connected and fixed to the first busbar 101 via its claws. Next, a flexible connector 130 (such as a cable, flexible connector, or copper busbar) is installed between the first busbar connector 110 and the second busbar connector 120 to facilitate current conduction. Simultaneously, the second busbar connector 120 is positioned using the adjusting assembly 1202 to align the connecting body 1201 with the second busbar. Adjustments in both the horizontal and vertical directions ensure precise alignment. Throughout the installation process, complex cable connections are unnecessary; installers only need to perform simple adjustments and fixations on the second busbar connector 120, thus reducing installation time and labor costs.

[0036] Furthermore, the connection device 100 is suitable for connecting various large and small busbars. By replacing the adapter parts of the first busbar connector 110 and the second busbar connector 120, interconnection between different busbar models can be achieved. Therefore, this can not only be applied to existing busbar systems but also adapt to future changes in busbar trunking design, ensuring its long-term practicality and stability.

[0037] In some embodiments, the adjustment assembly 1202 of the second busbar connector 120 includes a first adjustment plate 1203 and a second adjustment plate 1204. Specifically, the first adjustment plate 1203 is coupled to the first busbar connector 110 and arranged to be movable relative to the first busbar connector 110 along a first direction A (e.g., the horizontal direction). By adjusting its relative position, the first adjustment plate 1203 adjusts the position of the connecting body 1201 and the second adjustment plate 1204 in the first direction A. The first adjustment plate 1203 and the first busbar connector 110 can be connected by a slide rail, guide rail, or other mechanical structure to ensure smoothness and stability during movement. During adjustment, the first adjustment plate 1203 can be moved in the first direction A by rotating the adjusting bolt or other adjusting device, thereby precisely adjusting the connecting body 1201 in the horizontal direction and ensuring the docking accuracy of the busbar connection.

[0038] Furthermore, the second adjusting plate 1204 is coupled to the first adjusting plate 1203 and arranged to move relative to the first busbar connector 110 along a second direction B (e.g., vertical). By adjusting its position, the second adjusting plate 1204 further precisely adjusts the position of the connecting body 1201 in the second direction B, thereby achieving accurate docking between the first busbar 101 and the second busbar 102. The connection structure between the second adjusting plate 1204 and the first adjusting plate 1203 can adopt a sliding connection to ensure smooth movement in the vertical direction. During the adjustment process, a threaded adjustment device or other adjustment mechanism can also be used to ensure precise movement of the second adjusting plate 1204 in the vertical direction, thereby achieving docking.

[0039] The adjustment process of the connecting body 1201 is described further. The connecting body 1201 is coupled to the second adjusting plate 1204 and is adjusted in the second direction B as the second adjusting plate 1204 moves. Under the combined action of the first adjusting plate 1203 and the second adjusting plate 1204, the horizontal and vertical positions of the connecting body 1201 can be adjusted to ensure that the docking angle and positional relationship between the first busbar and the second busbar meet the installation requirements. The adjustment process is achieved by manually operating bolts or other adjusting devices. During the adjustment process, the docking position can be adjusted quickly and conveniently according to the specific site conditions.

[0040] In this way, through the dual adjustment of the first adjustment plate 1203 and the second adjustment plate 1204, the precise positioning of the connecting body 1201 in two directions can be achieved, ensuring the connection between the connecting body 120 and the small busbar 102. This ensures efficiency and safety during the connection process, while reducing the installation complexity and time costs associated with traditional cable connection methods.

[0041] In some embodiments, the first busbar connector 110 includes a cabinet 1101 and a cover 1102. Specifically, the cabinet 1101 provides support and accommodating space for the busbar connector. The cabinet 1101 has an opening for coupling a first adjustment plate 1203 to its internal structure. The size and shape of the opening are designed according to the dimensions of the required connector to ensure that the first adjustment plate 1203 can move and achieve the required adjustment. The cabinet 1101 is manufactured from a robust material (such as metal or high-strength alloy) to ensure sufficient mechanical strength and durability to withstand the current load and mechanical stress during the busbar connector connection process.

[0042] Furthermore, the cover plate 1102 is coupled to the opening of the cabinet 1101 to close the opening and, together with the first adjustment plate 1203, cover the area. The cover plate 1102 not only closes the cabinet 1101, protecting the internal components from external environmental influences, but also ensures the stability of the adjustment components during adjustment. The cover plate 1102 can be detachable for easy maintenance and inspection. The connection between the cover plate 1102 and the opening can be achieved through screws, clips, or other fixing mechanisms, ensuring a tight fit between the cover plate 1102 and the cabinet 1101, thereby improving the structural stability and safety of the connection device 100.

[0043] In some embodiments, the cabinet 1101 includes a plurality of openings, and the cover plate 1102 and the first adjusting plate 1203 respectively cover the openings on different surfaces of the cabinet 1101. That is, the first adjusting plate 1203 can be arranged on different surfaces of the cabinet 1101, and this is not specifically limited in the embodiments of this disclosure.

[0044] like Figure 5 and Figure 6 As shown, in some embodiments, the first adjusting plate 1203 includes a horizontal elongated hole 1205, and the connecting device 100 further includes a plurality of first connecting rods. Specifically, the first adjusting plate 1203 is provided with a plurality of horizontal elongated holes 1205 thereon, which are used for the first adjusting plate 1203 to move relative to the first busbar connector 110 in the horizontal direction (i.e., the first direction A). The length and position of the horizontal elongated holes 1205 are designed to be adjustable within a certain range and with the required precision to ensure that the first adjusting plate 1203 can be properly translated during installation.

[0045] Furthermore, multiple first connecting rods are used to couple the first adjusting plate 1203 to the opening of the first busbar connector 110. Each first connecting rod passes through a horizontal elongated hole 1205 on the first adjusting plate 1203 and connects to the opening of the first busbar connector 110. The two ends of the first connecting rod may be equipped with threads or snap-fit ​​structures to secure it to the opening of the first busbar connector 110 by bolts, nuts, or other fasteners. The number and size of the first connecting rods are adjusted according to the specific application requirements to ensure that the first adjusting plate 1203 remains stable during adjustment and can support the movement of the connecting body 1201 and the second adjusting plate 1204. For example, four first connecting rods may be used, respectively arranged at the four corners of the first adjusting plate 1203.

[0046] Through the coupling of multiple first connecting rods, a stable connection structure is formed between the first adjusting plate 1203 and the first busbar connector 110. The movement of the first adjusting plate 1203 within the horizontal elongated hole 1205 allows the connecting body 1201 and the second adjusting plate 1204 to be adjusted along the first direction A. Specifically, by loosening or tightening the first connecting rods using adjusting bolts or other adjusting tools, fine-tuning of the position of the first adjusting plate 1203 is achieved, ensuring the flexibility and adjustability of the busbar trunking connection device during installation, allowing adjustment of the positions of the large and small busbars as needed.

[0047] In some embodiments, the second adjusting plate 1204 is coupled to the first adjusting plate 1203 via a plurality of second connecting rods 1208. Specifically, the second adjusting plate 1204 includes a vertical elongated hole 1207. This vertical elongated hole 1207 is used for the second adjusting plate to move relative to the first adjusting plate 1203 in a vertical direction (i.e., the second direction B). The length and width of the vertical elongated hole 1207 can be designed according to the required adjustment range and precision to ensure that the second adjusting plate 1204 can slide during adjustment while ensuring a stable connection with the first adjusting plate 1203.

[0048] Furthermore, multiple second connecting rods 1208 pass through the vertical elongated hole 1207 and are coupled to the first adjusting plate 1203. Both ends of each second connecting rod 1208 can be connected to the first adjusting plate 1203 and the second adjusting plate 1204 via threads, snaps, or other fixing devices. The number and length of the second connecting rods 1208 are designed according to actual adjustment requirements to ensure that the second adjusting plate 1204 and the first adjusting plate 1203 maintain a stable connection during adjustment. The second connecting rods 1208 are used to couple the second adjusting plate 1204 to the first adjusting plate 1203, and during adjustment, allow the second adjusting plate 1204 to move along the second direction B to ensure that the connecting body 1201 can be adjusted as required in the vertical direction.

[0049] In some embodiments, the connecting body 1201 includes a fastener 150. The fastener 150 is connected to the second adjusting plate 1204. The fastener 150 may be made of metal and may be L-shaped, with two mutually perpendicular components connected to the connecting body 1201 and the second adjusting plate 1204 respectively. The fastener 150 ensures the stability of the connecting body 1201 and prevents it from shifting or displacing during adjustment. The fastener 150 can be fixed to the second adjusting plate 1204 by screws or other fixing methods, ensuring that the positions of both do not change, thereby improving the installation accuracy and reliability of the connecting body 1201.

[0050] See also Figure 4In some embodiments, the connection device 100 further includes a switching device 160. The switching device 160 is disposed within the cabinet 1101 and coupled between the first busbar 101 and the flexible connector 130. That is, the flexible connector 130 is electrically connected between the switching device 160 and the connection body 1201. The switching device 160 is used to control the electrical connection between the first busbar 101 and the second busbar 102. Specifically, the switching device 160 enables or disconnects the electrical connection between the first busbar 101 and the second busbar 102 through electrical control or mechanical means. The installation position of the switching device 160 can be close to the center of the cabinet 1101 for convenient operation and debugging during installation. The switching device 160 can take various forms, such as a manual switch, an electric switch, or an automatic switch, with the appropriate type selected according to actual needs. Through the switching device 160, the electrical connection between the busbars can be flexibly controlled according to power demand or troubleshooting needs, ensuring the safety and reliability of the power distribution equipment. For example, the switching device 160 can be a circuit breaker, and the manual switch of the circuit breaker can be arranged on the cover plate 1102.

[0051] In this way, by eliminating the terminal box circuit breaker on the small busbar, the relevant metering and protection functions are integrated into the power distribution unit of the large busbar, further simplifying the structure and installation process of the power distribution equipment. Eliminating cable connections not only reduces equipment costs but also decreases the complexity of on-site installation and the potential for cable connection failures, significantly improving the maintenance efficiency and reliability of the power distribution equipment.

[0052] In some embodiments, the cover plate 1102 includes a shielding portion extending toward one side of the first adjusting plate 1203. Specifically, the cover plate 1102 is provided with a shielding portion extending toward one side of the first adjusting plate 1203. The shielding portion is used to ensure that when the first adjusting plate 1203 moves along a first direction A (i.e., the horizontal direction), the cover plate 1102 and the first adjusting plate 1203 can tightly seal against the opening of the cabinet 1101. The length, width, and shape of the shielding portion are designed according to the actual contact area of ​​the cover plate 1102 and the first adjusting plate 1203 and the required sealing effect. The extended portion of the shielding portion forms good contact with the edge of the first adjusting plate 1203 and maintains sealing performance during adjustment, thereby preventing external dust, moisture, etc. from entering the interior of the cabinet 1101.

[0053] An effective sealing surface can be formed between the cover plate 1102 and the first adjusting plate 1203 through the blocking portion extending towards one side of the first adjusting plate 1203. Even if the first adjusting plate 1203 is adjusted along the first direction A during installation or operation, the blocking portion ensures that the contact between the cover plate 1102 and the first adjusting plate 1203 does not loosen, thereby maintaining a seal. The extension length and shape of the blocking portion can be determined according to the adjustable range of the first adjusting plate 1203.

[0054] The cover plate 1102 is coupled to the first adjusting plate 1203 through the blocking part and is sealed to the opening of the cabinet 1101. The connection between the cover plate 1102 and the cabinet 1101 can be fixed by means of buckles, screws or spring buckles, etc., to ensure that the cover plate 1102 is firmly fixed to the opening of the cabinet 1101.

[0055] In some embodiments, the connecting device 100 further includes a first seal 140 and a second seal. Specifically, the first seal 140 is coupled to the opening of the cabinet 1101 to seal the contact area between the cover plate 1102 and the first adjusting plate 1203. The first seal 140 may be made of rubber, silicone, or other highly sealing flexible materials, possessing good elasticity and durability. The first seal 140 ensures a tight seal between the cover plate 1102 and the first adjusting plate 1203, preventing dust, moisture, or other external substances from entering the cabinet 1101, thereby protecting the internal electrical components from external environmental influences. The size and shape of the first seal 140 are designed according to the size of the opening of the cabinet 1101 to ensure complete coverage of the contact surface between the cover plate 1102 and the first adjusting plate 1203, providing excellent sealing.

[0056] Furthermore, the second seal is coupled to the shielding portion of the cover plate 1102 and is adapted to seal the contact area between the shielding portion and the first adjusting plate 1203. The shielding portion can be located at the edge of the cover plate 1102 or adjacent to the first adjusting plate 1203. The installation of the second seal effectively prevents dust, moisture, or other contaminants from entering the cabinet 1101 through these joints. The material of the second seal is the same as that of the first seal 140, which can be a highly elastic, weather-resistant rubber or silicone material, capable of adapting to temperature changes and physical pressure during long-term operation of the cabinet 1101. The second seal improves the sealing performance of the power distribution equipment. The seal can be installed using a snap-fit, adhesive, or embedded connection method to ensure it is not easily detached or damaged during use.

[0057] In this way, the overall protection performance of the power distribution equipment is improved by using the first seal 140 and the second seal, ensuring that the equipment can operate stably for a long time in various harsh environments, while also reducing the frequency of maintenance and extending the service life of the power distribution equipment.
