[0003] Tubular busbar terminals are indispensable power accessories for power transmission and transformation. There are three types of traditional tubular busbar terminals: Figure 1 Shown in 1, 2, 3(a) figure 1 Pipes that need to be welded and have small diameters cannot obtain effective cross-sectional area, which cannot meet the effective cross-sectional area of carrier fluid, and the cost is high, and it is limited by the installation environment; (b) figure 2 The terminal is inserted into the tube and then pressed with pressure equipment. The disadvantage is that the contact resistance is large during the pressing process, and it is limited by the installation environment; (c) image 3 The terminal gets the blank first, and then processes it, which is costly and limited by the installation environment

The invention relates to a tubular bus O-shaped wiring terminal which comprises a locking mechanism, a tubular bus and an O-shaped wiring terminal. The O-shaped wiring terminal comprises a first terminal and a second terminal. The first terminal is provided with a first arc hole. The second terminal is provided with a second arc hole. The first terminal is internally provided with a first pin hole. The second terminal is internally provided with a second pin hole. The locking mechanism comprises an insulated rod, a first nut and a second nut. The tubular bus O-shaped wiring terminal has advantages of high convenience in field mounting, small contact resistance and high heat radiation performance. The tubular bus O-shaped wiring terminal can satisfy a requirement for large-current conveying. According to international patent classification (IPC), the tubular bus O-shaped wiring terminal is classified to the technical field of a power industry. The tubular bus O-shaped wiring terminal can be widely used for connection between various tubular bus wirings and equipment. The tubular bus O-shaped wiring terminal is a necessary power fitting in power transmission and transformation, and furthermore can satisfy a requirement in current conveying by means of a large-current bus.
Description
technical field [0001] The invention relates to an O-shaped terminal for a tubular busbar, belonging to the technical field of tubular busbar fittings. Background technique [0002] Tubular busbar Aluminum alloy tubular busbar is one of the key equipment (materials) in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment. [0003] Tubular busbar terminals are indispensable power accessories for power transmission and transformation. There are three types of traditional tubular busbar terminals: Figure 1 Shown in 1, 2, 3(a) figure 1 Pipes that need to be welded and have small diameters cannot obtain effective cross-sectional area, which cannot meet the effective cross-sectional area of carrier fluid, and the cost is high, and it is limited by the installation environment; (b) figure 2 The terminal is inserted into the tube and then pressed with ...
