This condition makes the installation process cumbersome and inefficient, especially in large projects. At the same time, due to the lack of linkage, the accuracy of the installation position of the connecting sheet is difficult to control and is easily disturbed by human factors, which may cause problems such as increased contact resistance, heating and power loss in electrical connection performance. In addition, during the later maintenance, since there is no linkage relationship, the disassembly and reinstallation need to be operated separately, which not only increases the difficulty and workload of maintenance, but also faces the challenge of installation accuracy again, which hinders the stable operation and efficient maintenance of the bus duct system.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0024] Referring to Figures 1-6

[0025] An interface connecting structure for intensive bus duct, comprising connecting cover 1 and multiple connecting pieces 2, connecting cover 1 bottom is provided with hidden groove 3, transmission groove 10 and adjusting groove 16, hidden groove 3 and adjusting groove 16 are respectively provided with storage screw rod 13 and adjusting screw rod 17, transmission groove 10 is provided with driving gear 11, storage screw rod 13 is connected with driving gear 11 through transmission mechanism, adjusting screw rod 17 is connected with driving gear 11 through linkage mechanism, connecting cover 1 is provided with rotating disc 12 connected with driving gear 11, storage screw rod 13 and adjusting screw rod 17 are respectively provided with hidden plate 4 and movable frame 6 through limiting mechanism, hidden plate 4 is L-shaped and is provided with fixing hole 5, which is convenient for fixing bolt to be inserted and finally connected on bus duct.

[0026] Multiple connecting pieces 2 are slidably penetrated by horizontal rod 7 corresponding to movable frame 6, horizontal rod 7 is provided with limiting frame 8 through dismounting bolt 9. The vertical section of horizontal rod 7 is rectangular, the vertical section of limiting frame 8 is cross-shaped, the rectangular design can avoid the rotation of connecting piece 2 on horizontal rod 7, and the cross-shaped limiting frame 8 can avoid the sliding off of movable frame 6 and connecting piece 2 from horizontal rod 7.

[0027] ​​​The transmission mechanism includes a transmission gear 14 mounted on the receiving screw 13, which meshes with the drive gear 11. The linkage mechanism includes a linkage gear 15 mounted on the adjusting screw 17, which meshes with the drive gear 11. The drive gear 11, transmission gear 14, and linkage gear 15 are all bevel gears, and the meshing relationship between the drive gear 11, transmission gear 14, and linkage gear 15 is all perpendicular meshing. This perpendicular meshing design enables power steering and transmission, ensuring the practicality of the device.

[0028] The limiting mechanism includes a limiting rod 18 installed in the concealed groove 3 and the adjusting groove 16, which slides through the concealed plate 4 and the movable frame 6. The limiting rod 18 effectively limits the concealed plate 4 and the movable frame 6, preventing them from rotating with the storage screw 13 and the adjusting screw 17.

[0029] Furthermore, the storage screw 13 has threads only on the outer wall of the portion inside the hidden groove 3, and the adjustment screw 17 has threads only on the outer wall of the portion inside the adjustment groove 16.

[0030] In use, the connecting piece 2 is a crucial component for connecting the dense busbar trunking. It is positioned between two dense busbar trunking sections and is interleaved with the conductor bar. The connecting cover 1 connects to the two dense busbar trunking sections. The fixing bolt passes through the fixing hole 5 and connects to the two dense busbar trunking sections. The hidden plate 4 is normally concealed within the hidden groove 3 and is only removed when needed, thus exposing the fixing hole 5. Multiple connecting pieces 2 need to secure the conductor bar in the middle, and these pieces need to be close together for fixation. This close proximity is achieved by the compression of two movable brackets 6. Specifically, this requires the rotation of the storage screw 13 and the adjusting screw 17.

[0031] Rotating the turntable 12 can cause the drive gear 11 to rotate. When the drive gear 11 rotates, it can drive the storage screw 13 and the adjusting screw 17 to rotate with the help of the transmission gear 14 and the linkage gear 15. When the storage screw 13 and the adjusting screw 17 rotate, the hidden plate 4 can move out of the hidden groove 3 and unfold, and the movable frame 6 will move closer, thereby realizing the compression of the connecting piece 2.

[0032] When the hidden plate 4 is exposed and the fixing bolt is installed on the fixing hole 5, and the fixing bolt is fixedly connected to the two compact busbars, the hidden plate 4 cannot move and retract into the hidden groove 3. Therefore, the storage screw 13 cannot rotate, so the drive gear 11 and the adjusting screw 17 and other components cannot rotate. Therefore, the connecting piece 2 can stably clamp and fix the conductor bar of the two compact busbars.

[0033] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
