[0031] As shown in the figure, the aluminum busbar connection assembly 100 according to the present invention includes an aluminum busbar connector 110 and an aluminum busbar housing 120. The aluminum busbar connector 110 is provided with a first through hole 111. The aluminum busbar housing 120 surrounds the aluminum busbar connector 110, and the aluminum busbar wire 112 of the aluminum busbar connector 110 extends out of the aluminum busbar housing 120. The aluminum busbar housing 120 has a first opening 121 and a second opening 122, which are respectively provided on both sides of the aluminum busbar connector 110 and aligned with the first through hole 111. In this way, the stud 151 of the bolt 150 can pass through the aligned first opening 121, the first through hole 111 of the aluminum busbar, and the second opening 122 to connect with the terminal side and form an electrical connection.

[0032] The aluminum busbar connecting assembly 100 further includes a gasket 130, which is disposed around the periphery of the first through hole 111 of the aluminum busbar connector 110. The gasket 130 has a cylindrical portion 131 fitted onto the inner wall of the first through hole 111 and an annular portion 132 on one side of the aluminum busbar connector 110 surrounding the first through hole 111.

This arrangement allows a channel perpendicular to the aluminum busbar to be formed on one side, guiding the extension direction of the stud 151 of the bolt 150 after it is inserted into the first through hole 111 of the aluminum busbar.

[0034] The aluminum busbar housing 120 surrounds the guide sleeve 140 and the aluminum busbar connector 110, and the other end of the guide sleeve 140 extends beyond the first opening 121 of the aluminum busbar housing 120.

[0035] A groove 123 is provided on the periphery of the end of the first opening 121. A fastening ring 223 is accommodated in the groove 123 for fixing the other end, i.e. the free end, of the guide sleeve 140 to the first opening 121 of the aluminum busbar housing 120, thereby fixing the position of the guide sleeve 140 relative to the first through hole 111 of the aluminum busbar and preventing the guide sleeve 140 from sliding against the aluminum busbar housing 120.

[0036] Figure 4This is a perspective view of the charging stand 300 according to the present utility model; Figure 5 This is a cross-sectional view of the charging dock 300 according to the present invention; and Figure 6 This is a perspective view of the terminal 210 and terminal sleeve 220 of the charging base 300 according to the present invention.

[0037] As shown in the figure, the charging base 300 according to this utility model includes a terminal connection assembly 200, a conductive bolt 150, and the aforementioned aluminum busbar connection assembly 100, as described above.

When the terminal connection assembly 200 is assembled with the aluminum busbar connection assembly 100, the terminal sleeve 220 of the terminal connection assembly 200 is aligned with the first through hole 111 of the aluminum busbar connector 110. The bolt 150 passes through the first through hole 111 of the aluminum busbar connector 110 of the aluminum busbar connection assembly 100 and is screwed into the terminal sleeve 220 of the terminal connection assembly 200, thereby mechanically or electrically connecting the terminal sleeve 220 and the aluminum busbar connector 110 together.

[0038] As shown in the figure, the stud 151 of the bolt 150 can be inserted from the second opening 122 of the aluminum busbar housing 120 through the first through hole 111 of the aluminum busbar connector 110 and thus the guide sleeve 140, and protrude from the guide sleeve 140, wherein the portion of the stud 151 protruding from the guide sleeve 140 has threads 152 for engaging with the internal threads 221 of the terminal sleeve 220 of the terminal connection assembly 200.

[0039] As shown in the figure, the second opening 122 of the aluminum busbar housing 120 has an outwardly protruding cylindrical aluminum busbar cavity 160 for accommodating the bolt head 153 of the bolt 150, and the bolt head 153 of the bolt 150 can slide within the aluminum busbar cavity 160. Furthermore, the aluminum busbar cavity 160 also serves as a guide for the sliding of the bolt 150.

[0040] The bolt head 153 of the bolt 150 is provided with an insulating cap 154, which can seal the aluminum busbar cavity 160, thereby electrically insulating the bolt head 153 from the outside of the aluminum busbar cavity 160.

[0044] The other end of the guide sleeve 140 extends out of the aluminum busbar housing 120 at the first opening 121. When the terminal connection assembly 200 and the aluminum busbar connection assembly 100 are assembled together, the other end of the guide sleeve 140 is inserted into the terminal cavity 241. The edge of the first opening 121 of the aluminum busbar housing 120 and the edge of the terminal cavity 241 of the terminal housing 230 have snap-fit ​​structures, so that the first opening 121 and the terminal cavity 241 engage and lock together.

[0045] The advantages of the charging base according to this utility model are that the charging base with aluminum busbar connection is divided into two parts: an aluminum busbar connection assembly and a terminal connection assembly. These two parts are connected by conductive bolts, which are connected to the aluminum busbar connection assembly. This reduces the number of parts. Original equipment manufacturers can manufacture the aluminum busbar connection assembly and the terminal connection assembly separately using standard technical means. During installation, the two parts only need to be plugged together and the bolts tightened to complete the installation operation. This is very advantageous in the space-constrained interior of a vehicle. At the same time, because the aluminum busbar connection assembly is plugged in, it can rotate at multiple angles to meet different installation requirements, making it highly versatile.

[0046] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon. The structures described in the various embodiments can be freely combined without causing structural or principle conflicts, thereby achieving more aluminum busbar connection components and charging bases while solving the technical problems of this utility model.
