Abstract
Description
Technical Field
[0001] The utility model relates to the field of power equipment, and particularly relates to a hard copper bar connection structure. Background Technique
[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch, and each branch is set as required. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage rooms and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment.
[0003] The hard copper bar is a power transmission device for connecting electrical components inside the switch cabinet. Therefore, a large number of hard copper bars will be arranged inside the switch cabinet. For the purpose of saving costs and facilitating maintenance, the hard copper bars used in the switch cabinet generally have an inflexible structure. Therefore, multiple copper bars are required for end-to-end connection at some corners. Most copper bar connections are to drill holes in the copper bars and then connect them through pins. This method not only takes time and effort, but also the drilling position error may cause problems with installation. Therefore, a copper bar connection structure has emerged. For example, a copper bar connection structure with the patent number CN21542068UD introduces a connection structure that can connect two copper bars in the vertical direction. It is found in the actual use process that the included angle between some copper bars is not 90°, so this type of connection structure cannot be used. Therefore, a new connection structure is needed to solve this problem. Content of the Utility Model

[0005] A hard copper bar connection structure includes a hard copper bar and a connection structure. The connection structure is installed at the left and right ends of the hard copper bar. The connection structure includes a base, a top cover and a conductive connection plate. Both the base and the top cover are circular boxes with one end open. The open end of the base is rotatably connected to the open end of the top cover. A plurality of longitudinal chutes are provided on the inner wall of the base. A plurality of sliders are provided on the outer periphery of the conductive connection plate. The plurality of sliders are located in the plurality of longitudinal chutes. A first opening is provided on the side of the base, and a second opening is provided on the side of the top cover. A threaded hole is provided in the middle of the top cover. The threaded hole is threadedly connected with a telescopic rod. One end of the telescopic rod is connected with a knob. The knob is located outside the top cover. The other end of the telescopic rod is connected with a push plate. The push plate is located inside the top cover.
[0006] Preferably, the bottom of the second opening is flush with the open end of the top cover.
[0007] Preferably, the push plate is made of insulating material.
[0008] Preferably, conductive blocks are respectively arranged at the upper and lower ends of the conductive connection plate.
[0009] Preferably, the upper and lower ends of the conductive connection plate are of a hemispherical structure with a higher middle part and a lower outer periphery.

[0011] 1. By arranging a connection structure in the utility model, two copper bars are respectively placed in the base and the top cover, and the two copper bars are connected through the conductive connection plate, so that the purpose of connecting the copper bars can be achieved. Moreover, by arranging the base and the top cover to be rotatably connected, copper bars in any two directions can be connected without punching, which improves the working efficiency and is simple to operate and convenient for loading and unloading.
[0012] 2. By respectively arranging conductive blocks at the upper and lower ends of the conductive connection plate, the copper bars can be further pressed through the conductive blocks, so that the two copper bars are more tightly connected after connection, and the problem of copper bar detachment is avoided.
[0013] 3. By arranging the two ends of the conductive connection plate to be of a hemispherical structure with a higher middle part and a lower outer periphery, it is convenient to insert the copper bars, and at the same time, the tight fit between the copper bars and the conductive connection plate can be ensured, and the problem of copper bar detachment is avoided.
