[0002] A three-phase copper bar usually consists of a copper conductor coil, a housing, a plug, an oil pit, insulating sheets, etc. Among them, the copper conductor coil uses high-purity electrolytic copper as raw material and is produced and processed by advanced casting processes and technologies. The housing and the plug are the protective covers and connection parts of the three-phase copper bar, which can make the copper bar safer and more stable. The three-phase copper bar assembly realizes efficient and stable power transmission through optimized structural design, material selection, and manufacturing processes. It has a wide range of application scenarios and plays a key role from power systems to electronic devices. Scientific maintenance methods further extend its service life and reliability.

[0003] Currently, for the existing three-phase copper bar assemblies, during use, it is not convenient to perform rapid assembly work. Traditional three-phase copper bar assemblies need to be connected and fixed with screws and cannot be quickly pre-positioned, resulting in inconvenient operation during installation. Therefore, improvements are made to address the above problems. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a three-phase copper bar assembly.

[0005] The technical solution adopted by the present invention to solve its technical problems is: A three-phase copper bar assembly includes a copper bar, a rear shell, and a limit and fixation structure. The copper bar is nested and fixedly arranged inside the rear shell. A front shell is fixedly arranged at the front end of the rear shell, and a nut is also provided on the front shell for fixing the front shell to an external frame. Through the setting of the copper bar, the copper bar is stably limited through the plastic sealing work of the rear shell. The front end of the rear shell is fixed to the front shell, and a silicon steel magnetic core is provided at the lower end of the front shell. Through the silicon steel magnetic core, it is convenient to connect with a conductive sheet. The conductive sheet has a first docking structure, a second docking structure, and a third docking structure. The first docking structure, the second docking structure, and the third docking structure are magnetically attracted and fixed to the silicon steel magnetic core, and then fastened with screws to assist in the docking and connection work between the copper bar and the conductive sheet. At the same time, the setting of the nut facilitates the fixation of the rear shell and the front shell through screws, realizing the connection and fastening of the rear shell, the front shell, and the machine shell; The limit and fixation structure is used for the fixation and limitation of the conductive sheet, quickly docking the copper bar with the conductive sheet, and at the same time performing preliminary limitation of the conductive sheet. The conductive sheet is limited by magnetic attraction, and the limit and fixation structure is arranged at the lower end of the front shell. The copper bar is plastic-sealed and fixed inside the rear shell. The rear shell is fixed to the front shell, and the copper bar is arranged through the front shell. A silicon steel magnetic core is provided at the lower end of the front shell, which can perform adsorption connection of the conductive sheet, thus facilitating the connection of the conductive sheet to the bottom of the copper bar. Then, by screwing the screw, positioning work can be performed, facilitating the wiring process. The setting of the nut facilitates the fixation of the rear shell, the front shell, and the external installation structure.

[0006] Specifically, the limit fixing structure is a silicon steel magnetic core. The silicon steel magnetic core limits and fixes the conductive sheet through magnetic attraction. The conductive sheet includes a first docking structure, a second docking structure, and a third docking structure.

[0007] Specifically, the limit fixing structure is a combination of a silicon steel magnetic core and a limit docking structure. The silicon steel magnetic core performs magnetic attraction, and the limit docking structure is used for mechanical limitation. The limit docking structure is adapted to the first docking structure, the second docking structure, and the third docking structure. Through the structural setting of the limit docking structure, the fixing work can be assisted. The silicon steel magnetic core and the limit docking structure cooperate to facilitate the limiting work of the first docking structure, the second docking structure, and the third docking structure. The first docking structure and the third docking structure have the same structure and are symmetrically arranged. The first copper sheet on the first docking structure is fixed to the first docking end seat, and a first fitting groove is opened on the first copper sheet to facilitate the fitting and adjustment with the limit docking structure.

A limit component is elastically and telescopically connected to the fixing frame. A fastening screw is threadedly connected to the fastening seat. The fastening seat in the limit docking structure is screwed and fixed to the rear shell through the fastening screw to achieve the positioning of the limit docking structure. Then, the first docking structure, the second docking structure, and the third docking structure are placed at the lower end of the silicon steel magnetic core and simultaneously placed inside the limit docking structure. At this time, the user touches and presses the pressing end frame, causing the pressing end frame to contract and drive the connecting rod to move in cooperation. The connecting rod is fixed to the telescopic connecting rod, driving the telescopic connecting rod to slide in the central limit seat and the fixed sleeve through the spring connecting rod, changing the positions of the first adapter bracket and the second adapter bracket.

At this time, the first copper sheet can be inserted through the first adapter slot, and at the same time, the second copper sheet in the second docking structure can also be inserted through the second adapter slot and the third adapter slot. The first adapter bracket and the second adapter bracket are used for limit connection. Then, the pressing end frame is released, and the pressing end frame rebounds under the action of the spring telescopic rod. The spring telescopic rod is in limit connection with the fixing frame. The rebound causes the first adapter bracket and the second adapter bracket to move back, limiting the first docking structure, the second docking structure, and the third docking structure. At this time, the first docking structure, the second docking structure, and the third docking structure can be combined and contacted with the copper bar to conduct electricity processing work.

At the same time, the limiting component is arranged on the fixing frame. Through the setting of the limiting component, it is convenient to perform the mechanical connection of the first docking structure, the second docking structure, and the third docking structure. Touching and pressing the end frame can make the telescopic mechanism cooperate to expand and contract, changing the positions of the first adaptation card frame and the second adaptation card frame, so as to be able to cooperate with the first adaptation groove and the third adaptation groove. Then release the pressing of the end frame, and the end frame returns to its original position, and the limiting work of the first docking structure, the second docking structure, and the third docking structure can be carried out.
