Abstract
Description
Technical Field
[0001] This utility model relates to a fixed connector for a stacked busbar trunking. Background Technology
[0002] Busbar trunking is an electrical device used for power transmission and distribution, widely used in industrial, commercial, and civil buildings. With the continuous development of power systems, the requirements for the safety, stability, and connection reliability of busbar trunking are becoming increasingly stringent. Especially in stacked busbar trunking structures, how to achieve a robust connection between conductive components and how to ensure stable electrical performance at the connection points have become key issues of concern in the industry.
[0003] Currently, common busbar trunking connection structures on the market mainly include bolted connections and plug-in connections. For example, a connector includes oppositely positioned connecting side plates, a clamping plate interlocking with the connecting side plates, an insulating component, a conductive component, a transition component, and multiple screws. The combination angle of the busbar trunking is achieved through a reversing component, and a flexible transition is achieved through a transition component.
[0004] However, the existing stacked busbar trunking structure has the following problems: the traditional busbar trunking connection structure does not have additional conductive facilities on the conductive plate, which may cause the busbar trunking to be mismatched with the corresponding installation part after it is connected. At the same time, the traditional plug-in structure is prone to loosening.
[0005] Therefore, there is an urgent need for a stacked busbar trunking fixed plug structure with good locking and adaptability. Utility Model Content
[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fixed connector for stacked busbar trunking, which has a better fixing effect, is easier to install, and has better compatibility with plugs. This utility model achieves its purpose as follows:
[0007] This utility model proposes a fixed connector for a stacked busbar trunking, comprising several conductive components. Each conductive component includes several staggered and stacked conductive plates and insert plates. Two insert plates are arranged opposite each other in the horizontal direction between adjacent conductive plates. Pressure plate assemblies are distributed on both the upper and lower sides of each conductive component. A clamping assembly is also included, which penetrates the conductive components and pressure plate assemblies and fixes them by pressing them with vertical pressure. The fixed connector also includes two upper pressure plates and two lower pressure plates, which are arranged opposite each other. The lower and upper surfaces of the upper pressure plates each have a groove. One side of the fixed connector has a slot that matches the cross-section of the conductive plate and the insert plate. Both the upper and lower surfaces of the fixed connector have protrusions that engage with the grooves and joints that fit against the vertical sides of the pressure plate assemblies, for locking the fixed connector.
[0008] Furthermore, the fixed power strip includes several plugs and a limiting plate that form a rectangular frame as a whole. The plugs and the limiting plate are integrally formed and connected. Each plug has a slot on one side that matches the cross-section of the conductive plate and the cross-section of the plug plate. The upper and lower sides of the limiting plate are integrally formed with a joint and a protrusion.
[0009] Furthermore, the insert plates are provided with a plurality of conductive parts, which are located on one side of the slot that matches the cross-section of the conductive plate and are used to abut against the conductive plate.
[0010] Furthermore, the conductive plate has two first tenons on its upper and lower end faces, and the insert plate has a second tenon on its upper and lower end faces that abuts against the vertical mating surface of the first tenons, for locking the conductive plate and the insert plate. The upper pressure plate has a third tenon on its lower end face that engages with the first tenon on the upper end face of the conductive plate to lock the upper pressure plate and the conductive plate in the horizontal direction. The lower pressure plate has a fourth tenon on its upper end face that engages with the first tenon on the lower end face of the conductive plate to lock the lower pressure plate and the conductive plate in the horizontal direction.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the structural design of interlocking protrusions and grooves and fitting the joint with the vertical side of the pressure plate assembly achieves a firm lock on the fixed plug, solving the problem of easy loosening of the fixed plug; the cooperation between the third tenon and the first tenon on the upper end face of the conductive plate and the fourth tenon and the first tenon on the lower end face of the conductive plate respectively achieves horizontal locking between the upper pressure plate and the conductive plate, and between the lower pressure plate and the conductive plate, further improving the structural rigidity; the abutting design between the conductive part and the conductive plate increases the length of the conductive part, improving the adaptability to plugs of different lengths and the installation firmness.

These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0020] Please refer to Figure 1-6This utility model provides a fixed connector for a stacked busbar trunking, comprising several conductive components 100. Each conductive component 100 includes several staggered conductive plates 110 and insert plates 120. Two insert plates 120 are horizontally positioned opposite each other between adjacent conductive plates 110. Pressure plate assemblies 400 are distributed on both the upper and lower sides of each conductive component 100. Each pressure plate assembly 400 includes two upper pressure plates 410 and two lower pressure plates 420. The upper pressure plates 410 and lower pressure plates 420 are positioned opposite each other. The lower end face of each upper pressure plate 410 has a groove 430. The upper end face of the plate 410 is provided with a groove 430; the fixed plug 500 also includes a pressing component 300, which passes through the conductive component 100 and the pressure plate component 400, and fixes the conductive component 100 and the pressure plate component 400 by pressing in the vertical direction. One side of the fixed plug 500 is provided with a slot 530 that matches the cross-section of the conductive plate 110 and the cross-section of the plug plate 120. The upper and lower end faces of the fixed plug 500 are provided with protrusions 510 that engage with the groove 430 and joints 520 that fit against the vertical side of the pressure plate component 400, for locking the fixed plug 500.
[0021] Understandably, the fixed power strip 500 includes several plugs 540 forming a rectangular frame and a limiting plate 550. The plugs 540 and the limiting plate 550 are integrally formed and connected. Each plug 540 has a slot 530 on one side that matches the cross-section of the conductive plate 110 and the cross-section of the plug plate 120. The upper and lower sides of the limiting plate 550 are integrally formed with a connecting part 520 and a protrusion 510. This design allows the fixed power strip 500 to be firmly locked in the busbar system, preventing loosening and detachment. Several conductive parts 560 are provided between the plug plates 120. The conductive parts 560 are located on one side of the slots 530 that match the cross-section of the conductive plate 110, and are used to abut against the conductive plate 110. The conductive parts 560 can increase the conductive area, thereby increasing... The plug-in plate 110 has two first tenons 111 on both its upper and lower end faces, and the plug plate 120 has a second tenon 121 on both its upper and lower end faces that abuts against the vertical mating surface of the first tenon 111, for locking the conductive plate 110 and the plug plate 120. The upper pressure plate 410 has a third tenon 440 on its lower end face, for engaging with the first tenon 111 on the upper end face of the conductive plate 110, to lock the upper pressure plate 410 and the conductive plate 110 in the horizontal direction. The lower pressure plate 420 has a fourth tenon 450 on its upper end face, for engaging with the first tenon 111 on the lower end face of the conductive plate 110, to lock the lower pressure plate 420 and the conductive plate 110 in the horizontal direction. This tenon structure design enhances the connection stability between the components.
[0022] In use, firstly, the conductive plate 110 and the insert plate 120 are arranged in an alternating layer according to the design requirements, so that the two insert plates 120 between adjacent conductive plates 110 form a stable electrical connection structure. Then, the upper pressure plate 410 and the lower pressure plate 420 are placed on the upper and lower sides of the conductive assembly 100, so that each tenon cooperates with the corresponding structure. Next, the slot 530 of the fixing insert 500 is aligned with the side of the conductive plate 110 and the insert plate 120, so that the protrusion 510 engages with the groove 430 and the joint 520 fits against the vertical side of the pressure plate assembly 400. Finally, the vertical pressure is applied by the pressing assembly 300 to firmly fix the entire structure together.
