Description

Technical Field

[0001] The invention relates to the technical field of bus ducts, and in particular to a spliced ​​bus duct based on a clamping structure. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] The bus duct connection in the prior art mainly relies on connectors, which have a relatively simple structure. Multiple partitions are arranged in the shell, and conductors connecting the two bus ducts are arranged on the partitions. This connection method is prone to the problem of unstable partition installation, which causes poor contact and leads to power outages.

[0004] A Chinese invention patent application with the publication number CN116260091A has been searched and disclosed a splicable bus duct, which only requires the connection claws to be inserted between adjacent insulating plates. It is easy to install, and the elastic force provided by the elastic roller can enable the insulating plates to clamp the connection claws, thereby ensuring sufficient contact between the conductive plates and the connection claws. However, when two sets of bus ducts are docked through a connector, the connection plate in the connector and the bus duct cannot be firmly connected only by the snap-fitting effect of the barbs, which can easily cause the connection plate to become unhooked and fall off during long-term use, posing certain safety hazards.

When the worker When the staff needs to assemble the bus duct, they can first place the shell 5 just above a group of bus duct transmission boards 9, and then press the positioning frame 4. Since the positioning frame 4 is fixedly connected to the annular cylinder 8019 in the four groups of clamping components 8, the annular cylinder 8019 can be driven to descend as a whole during the process of pressing the positioning frame 4. During the descent of the annular cylinder 8019, the protrusion 8014 inside it will also descend together.

At this time, the staff releases the positioning frame 4, and the second spring 8009 in the compressed state inside the first annular groove 8015 will immediately restore its deformation. When the second spring 8009 restores its deformation, the annular cylinder 8019 can be quickly lifted up and reset.When the annular cylinder 8019 is reset, the protruding portion 8014 will be located on one side of the steel ball 8018, and the protruding portion 8014 can play a good limiting role on the steel ball 8018, thereby realizing the rapid insertion and fixation of the first locking column 8003, and the four groups of clamping components 8 are respectively arranged at the four corners of the housing 5, which can ensure that the housing 5 is more stable and firm after installation.

At this time, the positioning frame 4 drives the annular cylinder 8019 to descend and the steel ball 8018 located in the annular groove 8017 contacts the circumferential inner wall of the top of the annular cylinder 8019 again. At this time, the steel ball 8018 cannot lock the first locking column 8003, and the first spring 8007 located inside the slide groove 8005 will be reset immediately, so that the angle between the two sets of movable plates 8011 can be reduced and stretched, and the slide seat 8012 can be lifted up to make the first locking column 8003 detach from the inside of the circular groove, which is convenient for the staff to quickly remove the shell 5 later and improve people's work efficiency.

[0046] In summary, with the aid of the above technical solution of the present invention, when the staff needs to assemble the bus duct, they can first place the shell 5 directly above a group of bus duct transmission boards 9, and then press the positioning frame 4. Since the positioning frame 4 is fixedly connected to the annular cylinder 8019 in the four groups of clamping components 8, the annular cylinder 8019 can be driven to descend as a whole during the process of pressing the positioning frame 4. During the descent of the annular cylinder 8019, the protrusion 8014 inside it will also descend together. As the protrusion 8014 continues to descend, its restriction on the steel ball 8018 inside the storage groove 8016 is gradually weakened. When the protrusion 8014 descends to the point where its top is on the same horizontal plane as the bottom of the steel ball 8018, the steel ball 8018 will be removed from the storage groove 80 16 rolls out until its circumferential outer wall contacts the circumferential inner wall at the top of the annular cylinder 8019.

At this time, the staff releases the positioning frame 4, and the second spring 8009 in the compressed state inside the first annular groove 8015 will immediately restore its deformation. When the annular tube 8019 is deformed, it can quickly lift up and reset. After the annular tube 8019 is reset, the protruding portion 8014 will be located on one side of the steel ball 8018. The protruding portion 8014 can play a good limiting role on the steel ball 8018, thereby realizing the rapid insertion and fixation of the first locking column 8003. The four groups of clamping components 8 are respectively arranged at the four corners of the shell 5, which can ensure that the shell 5 is more stable and firm after installation. When the shell 5 needs to be removed, the staff only needs to press the positioning frame 4 again. At this time, the positioning frame 4 drives the annular tube 8019 to descend, and the steel ball 8018 located in the annular groove 8017 contacts the circumferential inner wall of the top of the annular tube 8019 again. At this time, the steel ball 8018 cannot lock the first locking column 8003 The first spring 8007 located inside the slide groove 8005 will be immediately reset, so that the angle between the two sets of movable plates 8011 can be reduced and stretched, and the slide seat 8012 is lifted to make the first locking column 8003 disengage from the circular groove, which is convenient for the staff to quickly remove the shell 5 later, and improve people's work efficiency. After the shell 5 is installed, the conductive plate 21 and the insulating plate 17 arranged inside the shell 5 will also be inserted into the gap between the power transmission board 9 and the power transmission board 9. Then the staff rotates the rotating block 1501. In the process of rotating the rotating block 1501, the second threaded screw 1504 can be driven to rotate. In the process of rotating the second threaded screw 1504, it is meshed with the threaded hole opened on one side of the adjusting block 1505.The insulating plate 17 can drive the conductive plate 21 to move as a whole until the conductive plate 21 is close to the transmission board 9, ensuring the stability of the subsequent busbar splicing power supply. When the staff uses the adjustment component 15 to fasten the conductive plate 21 and the transmission board 9, the worm 1502 fixed on the outer wall of the second threaded screw 1504 will also drive the worm wheel 1503 to rotate. During the rotation of the worm wheel 1503, the first threaded screw 1404 can be driven to rotate. The rotation of the first threaded screw 1404 can make the threaded sleeve 1403 engaged on its outer wall drive the second locking column 1406 to move together. When the conductive plate 21 is close to the transmission board 9, the second locking column 1406 will also pass through the through hole opened on one side of the connecting plate 16, thereby achieving the fixation of the four sides of the shell 5, further ensuring the stability of the shell 5 after installation.
