[0002] Aluminum busbar flexible connectors are a common connection material. Composed of two parts, the aluminum busbar and the flexible connector, they offer excellent durability and reliability. Made from high-quality aluminum, they are lightweight, corrosion-resistant, and wear-resistant. The flexible connector's high flexibility effectively mitigates deformation and displacement caused by temperature fluctuations and structural movement, ensuring a secure and stable connection. During daily use, the flexible connector should be regularly inspected for damage and aging, and promptly replaced and maintained to ensure proper function.

[0003] The flexible connection structure on the market usually fixes the terminal block and the aluminum busbar by welding. If the connection is subjected to external force or after a long period of use, the connection is prone to separation, affecting the normal use of the aluminum busbar flexible connection structure.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] See Figure 1-6 A high-strength aluminum busbar flexible connection structure includes a main body component 1, the main body component 1 includes: a terminal block 11, a connecting portion 12 is provided between the terminal block 11 and the connecting portion 12, and a connecting component 2 is provided on the terminal block 11 and the connecting portion 12, and the connecting component 2 includes: a cavity 21, which is opened on the side of the terminal block 11 close to the connecting component 2; a rotating shaft 22, which is rotatably connected to the terminal block 11; a fixing rod 23, which is fixedly connected to the bottom of the rotating shaft 22; a worm gear 24, which is fixedly connected to the rotating shaft 2 2 outer wall; a worm 25 rotatably connected to the interior of the terminal block 11 and meshing with the worm gear 24, with one end of the worm 25 extending through and outside the terminal block 11; a turning handle 26 fixedly connected to the end of the worm 25 located outside the terminal block 11; an arcuate groove 27 defined on the side of the connecting portion 12 near the terminal block 11; a vertical groove 271 defined on the side of the connecting portion 12 near the terminal block 11, the vertical groove 271 intersecting and connecting the arcuate groove 27. The outer wall of the turning handle 26 is provided with anti-slip grooves 261. The width of the vertical groove 271 is equal to the diameter of the rotating shaft 22, and the height of the vertical groove 271 is equal to the diameter of the arcuate groove 27.

[0045] When in use, the staff inserts one end of the connecting portion 12 into the cavity 21 on the terminal block 11, and the rotating shaft 22 is inserted into the vertical groove 271. At this time, the fixing rod 23 is located inside the arc groove 27. The staff rotates the turning handle 26, and the turning handle 26 drives the worm 25 to rotate. The worm gear 24 engaged with the worm 25 drives the rotating shaft 22 to rotate. It is only necessary to control the worm gear 24 to drive the rotating shaft 22 to rotate clockwise (with Figure 6(Taking the direction shown as an example), the fixing rod 23 rotates clockwise in the arc groove 27. Since the worm 25 and the worm wheel 24 are interlocked, the fixing rod 23 and the rotating shaft 22 cannot be separated from the vertical groove 271 at this time, completing the fixation between the terminal block 11 and the connecting portion 12. The anti-slip groove 261 increases the friction between the staff's hand and the turning handle 26, making it easier for the staff to turn the turning handle 26. The width of the vertical groove 271 is equal to the diameter of the rotating shaft 22 to prevent the rotating shaft 22 from shaking in the vertical groove 271. The diameter of the fixing rod 23 is equal to the height of the arc groove 27 to prevent the fixing rod 23 from moving up and down in the arc groove 27. Both are used to increase the stability of the terminal block 11 after being connected to the connecting portion 12 to avoid affecting subsequent use.

[0046] Example 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See Figure 1-6 In addition to the worm 25 and the turning handle 26, the connection assembly 2 is provided with multiple groups, and the multiple groups of worm wheels 24 are all engaged with the worm 25. A protective assembly 3 is provided on the terminal block 11, and the protective assembly 3 includes: a bottom frame 31, which is provided at the bottom of the terminal block 11; a top frame 32, which is hinged to the top of the bottom frame 31; a limit rod 33, which is provided on a side wall of the top frame 32 close to the terminal block 11; a cavity 34, which is opened at the top of the bottom frame 31; a spring 35, which is symmetrically fixedly connected to the left inner wall of the cavity 34; and a cross bar 36, which is fixedly connected to the right end of the spring 35. The protective assembly 3 also includes a sliding rod 37 symmetrically fixedly connected between the inner walls of the cavity 34. The sliding rod 37 passes through the cross bar 36, and the cross bar 36 is slidably connected to the sliding rod 37.

[0049] The plurality of cavities 1 21 and the fixing rod 23 simultaneously fix and limit the connection portion 12 , thereby enhancing the fixing effect of the connection portion 12 . When the locking cam 33 is in the unlock state, the locking cam 33 is in the unlock state, and the locking cam 33 is in the unlock state, so that the locking cam 33 is locked. When the cross bar 36 is affected by the limit rod 33 to move left and right, the cross bar 36 slides on the slide rod 37, and the slide rod 37 guides the movement of the cross bar 36 to prevent the cavity 2 34 from tilting when it expands and contracts, which affects the fixing effect of the cross bar 36 on the limit rod 33.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
