[0002] With the continuous development of modern power systems, the use of power transmission and distribution bus ducts in power transmission is becoming more and more widespread. Bus ducts are a closed metal device composed of copper and aluminum busbars, which are used to distribute high power to various components of the distributed system. In indoor low-voltage power transmission trunk line projects, they have increasingly replaced wires and cables.

[0003] However, during the actual use of the above-mentioned equipment, when the external output terminals are connected to the bus duct, due to the large number of output terminals in the bus duct, errors may easily occur during the insertion of the external output terminals, resulting in the bending and damage of the output terminals, causing the output terminals to shift, thereby affecting the efficiency and stability of power transmission of the output terminals. In view of this, we propose a power transmission and distribution bus duct with a positioning structure. Utility Model Content

[0008] Preferably, the guide blocks and telescopic sleeves are arranged in multiple groups, and each group of guide blocks and telescopic sleeves are symmetrically distributed at the left and right ends of the outer wall of the horizontal axis of the positioning groove with the horizontal axis of the positioning groove as the symmetry axis, thereby improving the stability of the positioning groove.

DETAILED DESCRIPTION

[0022] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a power transmission and distribution bus duct with a positioning structure, including a bus duct 1, a positioning cavity 2 is fixedly connected at the top corner of the front surface of the bus duct 1, a rotating plate 21 is movably connected to the front surface of the positioning cavity 2, a handle 22 is fixedly connected to the lower side of the axis center of the front surface of the rotating plate 21, an output terminal 4 is arranged at the axis center of the front surface of the bus duct 1, and a positioning device is arranged inside the positioning cavity 2, the positioning device includes a positioning groove 23 on the upper surface of the inner wall of the positioning cavity 2, one end of the telescopic sleeve 26 is fixedly connected to the left surface of the inner wall of the positioning groove 23, the other end of the telescopic sleeve 26 is fixedly connected to a guide block 29, the upper surface of the inner wall of the guide block 29 is rotatably connected to a guide roller 25, the bottom of the inner wall of the telescopic sleeve 26 is fixedly connected to a telescopic thin rod 27, and the outer wall of the telescopic thin rod 27 is sleeved with a spring 28.

[0023] In one embodiment of the utility model, after the bus duct 1 is installed at a designated location, when it is necessary to connect the bus duct 1 to an external input terminal, the rotating plate 21 is opened by the handle 22, and the external terminal is inserted into the positioning cavity 2, and the external terminal is aligned with the gap in the positioning groove 23 for insertion, so as to avoid the external terminal from mistakenly contacting the output terminal 4 and causing the output terminal 4 to be bent and damaged, thereby improving the positioning performance of the device. In the process of inserting the external terminal into the positioning groove 23, the positioning device is started, and multiple groups of guide blocks 29 and telescopic sleeves 26 are provided, and each group of guide blocks 29 and telescopic sleeves 26 are symmetrically distributed at the left and right ends of the outer wall of the central axis of the positioning groove 23 in the horizontal direction with the central axis of the positioning groove 23 in the horizontal direction as the symmetry axis, thereby improving the stability of the positioning groove 23, and the external terminal contacts the guide block 29, and the guide block 29 is set to a trapezoidal structure, and the outer ribs of the guide block 29 are set to a rounded structure, and the guide block 29 is used in conjunction with the positioning groove 23 to realize the external input terminal The guiding effect of the guide block 29 can avoid the deviation of the external input terminal. The outer surface of the guide block 29 guides the external input terminal to the middle. Through the contact between the guide roller 25 and the external input terminal, the sliding friction on the outer surface of the external input terminal is converted into rolling friction, which reduces the loss of the conductive contacts on the left and right sides of the external input terminal and improves the smoothness of the external input terminal during insertion. Due to the extrusion force of the guide block 29 on the outer surface of the external input terminal, the telescopic sleeve 26 is squeezed inward, so that the telescopic sleeve 26 contracts and drives the telescopic thin rod 27 to contract, so that the reaction force of the spring 28 is presented, and the central axis of the telescopic sleeve 26 in the horizontal direction, the central axis of the telescopic thin rod 27 in the horizontal direction, and the central axis of the guide block 29 in the horizontal direction coincide with each other, thereby improving the stability of the telescopic sleeve 26. The reaction force of the spring 28 drives the guide block 29 to move rightward, so that the outer surface of the external input terminal is pressed by the guide block 29, thereby enhancing the positioning effect of the external input terminal.

[0024] In addition, in order to enrich the functionality of the device, a semicircular arc bar 3 is fixedly connected to the left surface of the positioning cavity 2, and a heat dissipation groove 31 is opened on the left surface of the inner wall of the positioning cavity 2. When the bus duct 1 works for a long time, a large amount of heat will be dissipated at the connection between the output terminal 4 and the external input terminal. The semicircular arc bar 3 is set as a hollow structure, and the cross-sectional area of ​​the inner wall of the semicircular arc bar 3 is adapted to the cross-sectional area of ​​the heat dissipation groove 31. At this time, the heat is discharged to the outside of the bus duct 1 through the heat dissipation groove 31 in cooperation with the semicircular arc bar 3, so that the external gas is exchanged with the hot gas in the positioning cavity 2, thereby improving the heat dissipation of the bus duct 1. When the bus duct 1 needs to be transported, the rotating plate 21 can be closed to make the positioning cavity 2 constitute a closed environment to prevent the bus duct 1 from colliding during transportation and causing impact damage to the output terminal 4, thereby improving the protection of the device and enriching the functionality of the device.

[0025] In the present invention, when in use, the positioning device is started. During the process of inserting the external terminal into the positioning groove 23, the external terminal contacts the guide block 29. The guide block 29 cooperates with the positioning groove 23 to guide the external input terminal, thereby avoiding the phenomenon of the external input terminal being offset. The outer surface of the guide block 29 guides the external input terminal to the middle. Through the contact between the guide roller 25 and the external input terminal, the sliding friction force on the outer surface of the external input terminal is converted into rolling friction force, thereby reducing the loss of the conductive contact pieces on the left and right sides of the external input terminal. Due to the extrusion force of the guide block 29 on the outer surface of the external input terminal, the telescopic sleeve 26 is squeezed inward, causing the telescopic sleeve 26 to contract and drive the telescopic thin rod 27 contracts, so that the reaction force of the spring 28 is present, thereby driving the guide block 29 to move to the right, so that the outer surface of the external input terminal is pressed by the guide block 29. After the bus duct 1 has been working for a long time, a large amount of heat will be emitted from the connection between the output terminal 4 and the external input terminal. At this time, the heat is discharged to the outside of the bus duct 1 through the heat dissipation groove 31 in cooperation with the semicircular arc bar 3, so that the external gas is exchanged with the hot gas in the positioning cavity 2. When the bus duct 1 needs to be transported, the rotating plate 21 can be closed to make the positioning cavity 2 constitute a closed environment to prevent the collision of the bus duct 1 during transportation and cause the output terminal 4 to be damaged by impact, thereby improving the protection of the device and enriching the functionality of the device.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
