Description

Technical Field

[0001] This application relates to the field of busbar devices, and more particularly to a busbar assembly. Background Technology

[0002] Busbar assemblies used in distribution boxes (distribution cabinets) are core components in power systems used for centralized distribution of electrical energy. A busbar assembly consists of a plastic housing and a three-phase busbar, typically made of a highly conductive metal (such as copper or aluminum). The busbar includes a conductor body and terminals, and the plastic housing is used to isolate the three-phase busbar.

[0003] In existing technologies, the conductor body and terminals of the busbar are integrally molded, and then a plastic housing is injection molded onto the busbar. In busbar assemblies manufactured in this way, the distance between adjacent terminals is fixed and cannot be adjusted, making it unsuitable for different application scenarios. Customized busbar assemblies are required for different usage needs, resulting in high manufacturing costs. Summary of the Invention

[0004] To improve the applicability of bus components, this application provides a bus component.

[0005] This application provides a bus component that adopts the following technical solution:

[0006] A busbar assembly includes an overlock machine and a conveying mechanism, the conveying mechanism being used to convey an edge binding mesh for wrapping the edge of fabric.

[0007] By adopting the above technical solution, and designing the conductor bodies into detachable groups, allowing the three-phase terminals to be flexibly connected to any group of conductor bodies, the problem of fixed spacing in traditional one-piece busbars is solved, enabling flexible adjustment of terminal spacing. Simultaneously, the modular structure improves the adaptability of the components, meeting the needs of different scenarios and reducing customized production costs. Furthermore, each group contains at least two conductor bodies, which can be stacked according to actual requirements, increasing the transmission current.

[0008] Optionally, it also includes an electrical connector for electrically connecting the conductor body and the three-phase terminals. The three-phase terminals and the conductor body are respectively mounted on opposite sides of the plastic housing. The plastic housing has multiple connecting holes that penetrate the mounting surfaces of the three-phase terminals and the conductor body. The power supply connector passes through the connecting holes, and each connecting hole corresponds to a set of conductor bodies and a three-phase terminal.

[0009] By adopting the above technical solution, the conductor body and three-phase terminals can be installed separately through electrical connectors and connecting holes, simplifying the assembly process while ensuring the reliability of the electrical connection. The directional design of the connecting holes ensures precise matching between each set of conductor bodies and corresponding terminals, avoiding the risk of misalignment, and can electrically isolate conductor bodies and terminals that are not electrically connected, improving the reliability and stability of the electrical connection.

[0010] Optionally, the busbar further includes a neutral busbar, and the terminal block further includes a neutral terminal block. The neutral terminal block is detachably electrically connected to the neutral busbar, and the plastic housing is used to isolate the neutral busbar from the conductor body.

[0011] By adopting the above technical solution, the addition of a neutral busbar and neutral terminal expands the component's functionality, enabling it to handle both three-phase power and the neutral wire simultaneously, thus meeting the needs of complex power distribution systems. The plastic housing's isolation of the neutral busbar further optimizes the electrical layout, reduces interference between the three-phase conductors and the neutral wire, and enhances system compatibility and safety.

[0012] Optionally, it also includes a conductive pad, on which a through hole is provided for the power supply connector to pass through, and three through holes are provided on the three-phase terminal block, each through hole corresponding to a set of conductor bodies and a connection hole, and the conductive pad is used to be inserted into the through hole.

[0013] By adopting the above technical solution, the conductive pad, through the cooperation of the through holes and connection holes, enhances the contact area between the three-phase terminal and the conductor body, reduces contact resistance, and improves conductivity stability. The plug-in design simplifies the installation process, enhances the vibration resistance of the connection, and prevents loosening or detachment due to external forces. Because of the conductive pad, a relatively flat three-phase terminal with three connection holes can be uniformly manufactured, eliminating the need for customization of the three-phase terminal based on the different conductor bodies being electrically connected, thus reducing processing costs and inventory backlog.

[0014] Optionally, the connecting hole extends along the arrangement direction of the three sets of conductor bodies and penetrates the plastic housing. A baffle is slidably disposed inside the connecting hole along the extension direction of the connecting hole. The connecting hole includes a connecting part and an isolation part. When one of the three-phase terminals corresponds to a set of conductor bodies, the connecting part connects the set of conductor bodies and the three-phase terminal. The power supply connector passes through the connecting part. The baffle is located in the isolation part. The baffle isolates the other two sets of conductor bodies and the three-phase terminal.

[0015] By adopting the above technical solution, the sliding baffle, in conjunction with the connecting and isolating parts, can physically isolate the other two sets of conductors when the selected conductor body is connected to the corresponding terminal, preventing accidental contact or short circuit. This design improves the safety of adjustment operations and ensures the independent working state of different sets of conductors. The position of the baffle can be adaptively adjusted according to actual usage requirements, improving the adaptability of the plastic housing, eliminating the need for customization of the plastic housing, and reducing processing costs and inventory buildup.

[0016] Optionally, a telescopic groove is provided on the wall of the connecting hole, and a locking block is slidably disposed in the telescopic groove. A locking groove is provided on the side wall of the baffle, and the locking block is used to insert into the locking groove to lock the baffle.

[0017] By adopting the above technical solution, the cooperation between the locking block and the locking groove achieves mechanical locking of the baffle. The sliding of the telescopic groove controls the position of the baffle, ensuring that the baffle is firmly fixed in the isolated state and avoiding accidental displacement due to vibration or misoperation. This design enhances the positioning accuracy and reliability of the baffle.

[0018] Optionally, the plastic housing has a transmission groove communicating with the telescopic groove. An operating member is slidably disposed in the transmission groove. An inclined transmission surface is formed on the operating member. The inclined transmission surface is used to slide against the lock block, so that the lock block is inserted into the lock groove. A reset elastic member is provided between the lock block and the groove wall of the telescopic groove. The reset elastic member is used to drive the lock block out of the lock groove.

[0019] By adopting the above technical solution, the linkage design between the transmission ramp and the operating component allows the insertion and removal of the lock block to be completed with a single operating component, simplifying the locking / unlocking process. The reset elastic component ensures automatic lock block reset, improving operational convenience and reliability. It also reduces the risk of human error; if the operator accidentally misplaces the baffle, the baffle can be unlocked and its position adjusted by moving the operating component.

[0020] Optionally, the transmission groove extends through the surface of the plastic housing, the operating component includes an operating part that extends through the transmission groove and is held by an operator, a sliding groove is provided on the groove wall of the transmission groove, a baffle is slidably disposed in the sliding groove, the baffle is fixedly connected to the operating component, and the baffle is used to slide to block the transmission groove.

[0021] By adopting the above technical solution, the exposed design of the operating part of the operating component facilitates manual hand operation. The cooperation between the baffle and the slide can close the transmission groove when not in operation, preventing dust or foreign objects from entering and affecting the operation of the mechanism, thus improving the protection and service life of the components and enhancing the aesthetics.

[0022] Optionally, the transmission groove is connected to two adjacent locking grooves arranged along the arrangement direction of the multiple connecting holes, and the operating element is used to drive the two adjacent locking blocks to move synchronously.

[0023] By adopting the above technical solution, the synchronous linkage between the operating component and the adjacent locking block allows for simultaneous operation of the baffles on both sides, significantly improving adjustment efficiency, reducing repetitive operation steps, and making it suitable for scenarios that require rapid switching of connection modes.

[0024] Optionally, the locking blocks and operating components are provided in two sets, which correspond one-to-one. The two sets of locking blocks and operating components correspond to the two side sets of conductor bodies in the three sets of conductor bodies respectively. Each connecting hole has two baffles, and each baffle corresponds to one set of conductor bodies.

[0025] By adopting the above technical solution, two sets of locking blocks and operating components are set, and the two sets of locking blocks and operating components are located at the outermost edge. In conjunction with two baffles, if the two baffles are also located at the outermost edge, the two sets of locking blocks and operating components can lock the two baffles respectively to prevent them from coming out of the connecting holes of the baffles. If one of the baffles is located in the middle, that is, the conductor body in the middle position, then only one set of locking blocks and operating components is used to lock the other baffle. The baffle located in the middle is sandwiched between the baffles on the side and the terminal block, and no locking is required. This minimizes the locking structure and reduces the processing cost to the greatest extent.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. It enables flexible adjustment of the spacing between wiring terminals, which can meet the needs of different scenarios, reduce customized production costs, and increase the transmission current;

[0028] 2. Due to the presence of conductive pads, relatively flat three-phase terminals with three connection holes can be uniformly processed, eliminating the need to customize three-phase terminals based on the different conductors connected to them, thus reducing processing costs and inventory backlog.

[0029] 3. The position of the baffle can be adaptively adjusted according to actual usage needs, improving the adaptability of the plastic shell, eliminating the need for customization of the plastic shell, and reducing processing costs and inventory backlog. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] Example 1:

[0040] Embodiment 1 of this application discloses a bus assembly. (Refer to...) Figure 1 The bus assembly includes a bus 1 and a plastic housing 2. The bus 1 includes three sets of conductor bodies 11 and multiple terminals 12. Each set has at least two conductor bodies 11. The conductor bodies 11 in the same set are detachably connected. The terminals 12 include three-phase terminals 121. Each three-phase terminal 121 is detachably electrically connected to any set of conductor bodies 11. The plastic housing 2 is used to isolate each set of conductor bodies 11 and each three-phase terminal 121.

[0041] Reference Figure 1 The plastic housing 2 has three separately arranged mounting slots 24, which penetrate two opposite sidewalls of the plastic housing 2. Each of the three mounting slots 24 is used to place and install three sets of conductor bodies 11. Multiple separately arranged fixing slots 25 are formed on the surface of the plastic housing 2 opposite to the mounting slots 24. The arrangement direction of the fixing slots 25 is perpendicular to the arrangement direction of the three mounting slots 24. The fixing slots 25 are used to place and install terminals 12.

[0042] Reference Figure 1In this embodiment, each group has two conductor bodies 11. The two conductor bodies 11 in each group are electrically connected by a bolt assembly. The two conductor bodies 11 in each group are arranged in a direction perpendicular to the arrangement direction of the three groups of conductor bodies 11 and perpendicular to the arrangement direction of the plurality of terminals 12.

[0043] Reference Figure 2 The bus assembly also includes electrical connectors, which are screws (not shown in the figure). Multiple through holes 21 are provided on the plastic housing 2 along the arrangement direction of the two conductor bodies 11 in each group. Each through hole 21 connects a three-phase terminal 121 to a group of conductor bodies 11. A connection hole 123 is provided on each three-phase terminal 121 along the arrangement direction of the two conductor bodies 11 in each group. The connection hole 123 corresponds to and connects with the through hole 21. Multiple mounting holes 111 are provided on the conductor body 11 along the arrangement direction of the two conductor bodies 11 in each group. The mounting holes 111 correspond to the connection holes 123 and the through holes 21. Electrical connectors are inserted into and pass through the connection holes 123, through holes 21, and mounting holes 111 to fix a three-phase terminal 121 and a group of conductor bodies 11 to the plastic housing 2 and achieve electrical connection between them.

[0044] Reference Figure 3 The busbar 1 also includes a neutral busbar 13, which is located on opposite sides of the conductor body 11 in the plastic housing 2, isolating the neutral busbar 13 from the conductor body 11. The plastic housing 2 has a receiving groove 26 extending along the arrangement direction of the terminals 12, for placing and installing the neutral busbar 13. The terminals 12 also include a neutral terminal 122, which is spaced apart from the three-phase terminals 121, and is electrically connected to the neutral busbar 13.

[0045] The assembly principle of a busbar assembly according to Embodiment 1 of this application is as follows: First, the operator stacks two conductor bodies 11 from each group of conductor bodies 11 together and places them into different mounting slots 24. Then, according to the arrangement of the connecting holes 21 on the plastic housing 2, the corresponding three-phase terminals 121 are placed in the fixing slots 25. The three-phase terminals 121 and the conductor bodies 11 are fixed using electrical connectors. Next, the neutral busbar 13 is placed in the receiving slot 26, and then the neutral terminal 122 is placed in the remaining fixing slots 25. The neutral terminal 122 and the neutral busbar 13 are fixed using electrical connectors.

[0046] Example 2:

[0047] Reference Figure 4Unlike Embodiment 1, the three-phase terminal 121 in this embodiment has three connection holes 123, each corresponding to a mounting slot 24. The three-phase terminal 121 is a flat sheet. A conductive pad 3 is inserted into the connecting hole 21. A through hole 31 is formed on the conductive pad 3, connecting a mounting slot 24 and a fixing slot 25. The power supply connector is inserted and passes through the connection hole 123, the through hole 31, the connecting hole 21, and the mounting hole 111 to fix a three-phase terminal 121, a conductive pad 3, and a set of conductor bodies 11 onto the plastic housing 2, and to achieve electrical connection between the three.

[0048] Reference Figure 4 The connecting hole 21 penetrates the plastic shell 2 along the arrangement direction of the three sets of conductor bodies 11. Two baffles 4 are slidably installed in each connecting hole 21, and the two baffles 4 are arranged along the arrangement direction of the three sets of conductor bodies 11.

[0049] Reference Figure 4 The connecting hole 21 includes a connecting part 211 and an isolation part 212. When one of the three-phase terminals 121 corresponds to a set of conductor bodies 11, the connecting part 211 connects the set of conductor bodies 11 and the three-phase terminal 121. The power supply connector passes through the connecting part 211, and the baffle 4 is located in the isolation part 212. The baffle 4 isolates the other two sets of conductor bodies 11 and the three-phase terminal 121.

[0050] Reference Figure 4 and Figure 5 The baffle 4 has a locking groove 41 extending along the arrangement direction of the terminals 12. The arrangement direction of the terminals 12 is set to left and right, and the arrangement direction of the three sets of conductor bodies 11 is front and back. The left and right walls of the connecting hole 21 have telescopic grooves 22 extending in the left and right direction. A locking block 5 is slidably installed in the telescopic groove 22. The end of the locking block 5 is used to extend out of the telescopic groove 22 and insert into the locking groove 41 to lock the baffle 4 onto the plastic housing 2. The conductive pad 3 also has a locking groove 41.

[0051] Reference Figure 5 and Figure 6 and Figure 7The plastic housing 2 has transmission grooves 23 extending vertically on both its front and rear side walls, which are connected to two adjacent telescopic grooves 22 in the left and right directions. An operating member 6 is slidably installed within the transmission groove 23. Transmission ramps 61 are formed on the left and right side walls of the operating member 6, with the distance between the two ramps 61 decreasing downwards. The transmission ramps 61 slide against the locking block 5. When the operating member 6 moves downwards, the transmission ramps 61 push the locking block 5 out of the telescopic groove 22 and into the locking groove 41. A reset elastic member 7, which is a spring sheet, is pressed between the locking block 5 and the groove wall of the telescopic groove 22. The reset elastic member 7 extends and retracts in the direction that drives the locking block 5 out of the locking groove 41.

[0052] Reference Figure 6 and Figure 7 The operating component 6 includes an operating part 62, which extends out of the transmission groove 23 and is held by the operator. A sliding groove 231 extending in the vertical direction is provided on the upper wall of the transmission groove 23. A baffle plate 8 is slidably installed in the sliding groove 231. The baffle plate 8 is fixedly connected to the operating component 6 and can move with the operating component 6 to block the transmission groove 23.

[0053] Reference Figure 5 The locking block 5 and the operating component 6 are each provided in two sets and correspond one-to-one. The two sets of locking blocks 5 and operating components 6 correspond to the two sets of conductor bodies 11 located at the front and back, respectively.
