Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to a busbar electrical connection structure which occupies a small space. Background Art

[0002] In today's electrical field, integrated busbars are crucial conductors, carrying the critical task of centrally collecting or distributing current from multiple electrical branches. Typically, busbars are crafted from highly conductive metals such as copper or aluminum and often appear as long strips. This long design facilitates layout and connection within electrical systems.

[0003] Currently, common busbars generally consist of a base and multiple metal busbars arranged side by side across the width of the base. With the increasing complexity of electrical systems and the increasing requirements for power distribution, the number of metal busbars has in many cases become an important factor affecting the busbar's power connection and distribution capabilities. The greater the number of metal busbars, the stronger the busbar's power connection and distribution capabilities will be, and it will be able to better meet the needs of complex electrical systems. However, this increase in number also brings about problems that cannot be ignored. A larger number of metal busbars will directly lead to an increase in the width of the busbar, making the busbar larger in overall size.

[0004] In actual applications, especially when installing in electrical cabinets, busbars with wider widths will take up more space. This will not only have a serious impact on the rational layout of other electrical components in the cabinet, but also make the already limited space even more crowded, making it difficult to achieve coordinated installation and normal operation of various components. Moreover, in some special application scenarios with limited space, such as small electrical equipment and compact electrical control systems, busbars with wider widths may cause great installation difficulties. It may even be impossible to install due to lack of space, or special modifications and designs to the electrical cabinet may be required, which increases costs and engineering complexity. Therefore, how to effectively reduce the space occupied by the busbar while ensuring its strong power connection and distribution capabilities has become a key technical problem that needs to be solved in the current electrical field.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference as follows Figures 1-10 The utility model is described as follows:

[0030] Embodiment: A busbar connection structure that takes up minimal space includes a base 1 made of plastic and having an overall elongated shape. An upper mounting groove 2 is provided on the upper side of the base 1, within which an upper busbar 3 is mounted. A lower mounting groove 4 is provided on the lower side of the base 1, within which a lower busbar 5 is mounted. The provision of the upper mounting groove 2 provides a stable mounting position for the upper busbar 3, ensuring that the upper busbar 3 will not easily move or become loose during use.

[0031] Three lower mounting slots 4 are provided, spaced apart across the width of the base 1. The upper mounting slot 2 also provides a single slot. These three lower mounting slots 4 accommodate multiple lower busbars 5, increasing the busbar's current transmission capacity and meeting the current distribution and collection requirements of various electrical systems. These spaced lower mounting slots 4 effectively utilize the space within the base 1, preventing interference between the lower busbars 5 and improving the busbar's reliability and stability.

[0032] A plurality of electrical terminals 6 are provided on the left and right sides of the base body 1 , respectively. The electrical terminals 6 are electrically connected to the upper bus bar 3 or one of the lower bus bars 5 .

[0033] One end of the upper busbar 3 and the lower busbar 5 in the longitudinal direction extends out of the base body 1 to form a power connection terminal. The design of the power connection terminal facilitates the connection between the busbar and an external power supply or other electrical equipment, improving the convenience and reliability of the connection.

[0034] Used to distribute electrical energy between upper busbar 3 and lower busbar 5. The provision of power terminals 6 facilitates connection of the busbar to various electrical devices, enabling the transmission and distribution of electrical energy. Connecting power terminals 6 to electrical devices allows for the distribution of electrical energy to different devices based on their specific needs, enhancing the flexibility and scalability of the electrical system.

[0035] This design with upper and lower busbars 3 and 5 arranged one above the other has significant advantages. By arranging the upper and lower busbars 3 and 5 one above the other, rather than the traditional arrangement of multiple busbars arranged side by side on the same plane, the overall width of the busbars is effectively reduced.

[0036] In space-constrained applications like electrical cabinets, busbar width is a critical factor. A smaller width means less space, allowing for a more rational layout of other electrical components within the cabinet, improving space utilization. This also provides greater flexibility in cabinet design, eliminating the need to compromise on size due to excessive busbar width.

[0037] This design not only reduces the space occupied by the busbar within the electrical cabinet but also offers other benefits. For example, the smaller width makes it easier to operate during installation, reducing the difficulty and complexity of installation. Furthermore, the smaller width helps reduce mechanical stress on the busbar during operation, improving its reliability and stability.

[0038] In summary, the design of the upper busbar 3 and the lower busbar 5 arranged vertically is an innovative solution that can effectively solve the problem of the busbar occupying a large space and bring many conveniences to the design and installation of the electrical system.

[0039] The base body 1 is composed of multiple connected units 11. A first insertion slot 12 is provided on one side of each unit 11, and a first insertion strip 13 is provided on the other side. Two adjacent units 11 are connected by the first insertion strip 13 engaging with the first insertion slot 12. This insertion engagement allows for removable connection. This simple and effective connection ensures stability between the units 11 while facilitating disassembly and adjustment when necessary.

[0040] The base 1 is composed of multiple connected unit blocks 11, making its length controllable and variable. In practical applications, different electrical cabinets and different electrical systems may have different busbar length requirements. This design of connectable unit blocks 11 allows the length of the base 1 to be appropriately adjusted according to specific needs. For example, in a small electrical cabinet, a shorter base 1 length can be selected to avoid excessive busbar length and space occupation. In larger electrical systems requiring longer busbars, multiple unit blocks 11 can be connected to meet the required length.

[0041] This length-controllable design can better adapt to different installation environments and requirements, increasing the busbar's versatility and flexibility. It also helps reduce the space occupied by the busbar within the electrical cabinet. Because the length of the base body 1 can be precisely adjusted based on actual conditions, the space wasted by an overly long busbar is avoided, resulting in more efficient use of cabinet space.

[0042] In summary, the design in which the seat body 1 is formed by connecting multiple unit seats 11 is an ingenious solution, which not only realizes the controllability of the length of the seat body 1, but also provides strong support for reducing the space occupied by the busbar in the electrical cabinet.

[0043] The left and right sides of the unit base 11 are connected to side panels 14, each with a second insertion slot 15 formed on each side. The side panels 14 are provided with second insertion strips 16 that plug into the second insertion slots 15. This plug-and-socket connection ensures a secure and easy-to-disassemble connection between the side panels 14 and the unit base 11. During installation and maintenance, assembly and disassembly are facilitated, improving work efficiency.

[0044] The side plate 14 is provided with a slot 17 for the electrical terminal 6 to pass through, and a detachable baffle 18 is connected to the slot 17 .

[0045] The side panel 14 is provided with a slot 17 for the power terminal 6 to pass through. The design of this slot 17 is very clever, and it facilitates the installation and use of the power terminal 6. The power terminal 6 can be installed and used according to actual needs, and has high flexibility. When a power terminal 6 is not needed at a certain position, the side panel 14 and the baffle 18 can block that position. This can prevent the outside from contacting the upper bus bar 3 and the lower bus bar 5 at that position, thereby improving the safety of the entire busbar. The detachable design of the baffle 18 further enhances this flexibility. When the power terminal 6 needs to be set, the baffle 18 can be removed so that the power terminal 6 can be smoothly extended and connected to the external electrical equipment.

[0046] This design not only improves busbar safety but also allows for flexible adjustment to suit different electrical connection requirements. It also helps maintain the busbar's neatness and aesthetics, avoiding potential safety hazards and visual clutter caused by unnecessary exposed parts.

[0047] In summary, the structural design of the unit base 11 and the side plate 14 and the detachable design of the baffle 18 provide strong guarantees for the safe use and flexible configuration of the busbar, further improving the practicality and reliability of the busbar.

[0048] One end of the base 1 is connected to a connection base 7, which is provided with first connection slots 8 corresponding to the three lower mounting slots 4. The lower busbar 5 extends into these first connection slots 8, while the upper busbar 3 extends into the middle first connection slot 8. The base also includes wiring terminals 9 that extend into these first connection slots 8 and connect to the lower busbars 5. This design makes the busbar connection more stable and reliable, facilitating the transmission and distribution of current. The connection of the wiring terminals to the lower busbar 5 in the first connection slots allows for convenient connection to external circuits, enhancing the busbar's practicality.

[0049] The connection base 7 is provided with second connection slots 10 on both sides, and the three first connection slots 8 are located between the two second connection slots 10. This layout rationally utilizes space, making the structure of the connection base more compact. It also includes an adapter 20, which is U-shaped. The two ends of the adapter 20 are bent to form electrical connection pins 21. The middle of the adapter 20 is connected to the upper bus bar 3. The electrical connection pins 21 at both ends of the adapter 20 extend into the second connection slots 10. It also includes terminal blocks 9 that extend into the second connection slots 10 and connect to the electrical connection pins 21. The design of the adapter 20 provides more possibilities for connecting the upper bus bar 3. The upper bus bar 3 can be connected to an external circuit through the adapter 20, further expanding the application range of the busbar.

[0050] The design of the connector and related components not only makes the bus connection more stable and reliable, but also improves the practicality and scalability of the bus, providing strong support for the connection and operation of the electrical system.

[0051] An insulating block 31 is installed in the first connecting slot 8. Located between the adapter 20 and the lower busbar 5, this block provides electrical isolation. In an electrical system, ensuring electrical isolation between different conductive components is crucial to prevent safety issues such as electrical short circuits and leakage. The presence of the insulating block 31 effectively separates the adapter 20 from the lower busbar 5, ensuring the safe transmission of current along their respective paths and enhancing the safety and reliability of the busbar.

[0052] A guide groove 32 is provided on the side of the first connecting groove 8, and a guide bar 33 is provided on the side of the insulating block 31 that is slidably connected to the guide groove 32. The guide bar 33 cooperates with the guide groove 32 to position and restrict the insulating block 31. First, the cooperation between the guide bar 33 and the guide groove 32 serves to position the insulating block 31. During installation and use, the insulating block 31 can accurately slide into the guide groove 32 through the guide bar 33, ensuring that its position in the first connecting groove is accurate, thereby better playing the role of electrical isolation. Secondly, the guide bar 33 and the guide groove 32 also serve to restrict the insulating block 31. During the operation of the busbar, the insulating block 31 may be affected by external forces, and the cooperation between the guide bar 33 and the guide groove 32 can prevent the insulating block 31 from displacement or loosening, thereby ensuring the stability and reliability of the insulating block 31.

[0053] The design of the insulating block 31 in the first connecting groove and the guide bar 33 and the guide groove 32 not only achieves electrical isolation and improves the safety of the bus, but also ensures the stability of the insulating block 31 through positioning and limiting effects, providing a strong guarantee for the normal operation of the bus.

[0054] At least two partitions 19 are provided on the unit base 11, and the power terminals 6 are provided between two adjacent partitions 19. The upper mounting groove 2 is provided on the upper side of the partition 19.

[0055] First, the power terminals 6 are positioned between two adjacent partitions 19. The partitions 19 provide a degree of isolation and protection for the power terminals 6. In electrical systems, power terminals 6 often need to connect to external electrical equipment. The partitions 19 prevent accidental contact between adjacent power terminals 6, thus avoiding safety issues such as short circuits. Furthermore, the partitions 19 reduce external interference with the power terminals 6, improving their stability and reliability.

[0056] Secondly, the upper mounting slot 2 is located above the partition 19. This layout creates a certain amount of spatial separation between the upper busbar 3 and the partition 19. On the one hand, the partition 19 provides support and fixation for the upper busbar 3, preventing it from shifting or loosening during use. On the other hand, the partition 19 also provides a certain degree of electrical isolation, reducing electrical interference between the upper busbar 3 and other components, thereby improving the performance and safety of the busbar.

[0057] In summary, the partition 19 design on the unit seat 11 not only provides isolation and protection for the power terminals 6, but also supports, fixes and electrically isolates the upper busbar 3, further improving the safety and reliability of the busbar.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
