Description

Technical Field

[0001] This utility model relates to the field of charging mechanisms, and in particular to aluminum busbar adapter boxes for electrical wires. Background Technology

[0002] With the continuous development of new energy vehicles, car manufacturers are exploring new ways to output DC cables from the charging base. Using wires directly is currently limited by the wire diameter, while using aluminum busbars is subject to a series of problems such as difficult assembly and high cost. Therefore, the direction pursued by every company is to be compatible with large-diameter wires, easy to assemble, and cost-effective.

[0003] Currently, most charging docks on the market still use direct cable output. Directly connecting the DC power supply to aluminum busbars is limited by assembly and cost issues, causing many automakers to hesitate to use aluminum busbars. This significantly restricts automakers' development of charging docks, making it difficult to meet the increasingly demanding market requirements without new solutions. Directly soldering cables to the charging dock terminals would be difficult to install due to the excessive thickness of the cables, and the cost of fixing the cables would be high. Using aluminum busbars directly requires a large amount of space for installation and is also costly. Utility Model Content

[0004] To overcome the shortcomings of existing charging docks, such as large space occupation and high cost, this utility model provides an aluminum busbar adapter box for electrical wires.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an aluminum busbar adapter box for wires, including wires, aluminum busbars, outer shell, inner shell, back cover, sealing mechanism one, and sealing mechanism two. One end of the wire is welded to one end of the aluminum busbar. An inner shell is installed at the connection between the wire and the aluminum busbar. Sealing mechanism one is provided inside the inner shell. The inner shell is connected to the outer shell. A back cover is connected to the rear opening of the outer shell. Sealing mechanism two is provided between the back cover and the outer shell.

[0006] According to another embodiment of the present invention, the inner shell further includes an upper cover and a lower cover, the upper cover has protrusions on both sides, the lower cover has locking blocks on both sides of the inner wall, and the protrusions have locking holes for inserting the locking blocks.

[0007] According to another embodiment of the present invention, the aluminum strip end is provided with slots on both sides, and a U-shaped block is provided on the inner wall of the lower cover, the U-shaped block cooperating with the two slots.

[0008] According to another embodiment of the present invention, the outer shell is further provided with a locking block on the inner wall and a groove for embedding the locking block on the inner shell.

[0009] According to another embodiment of the present invention, the outer wall of the outer shell is provided with a second locking block, and the rear cover is provided with a protrusion, the protrusion being provided with a locking hole for passing through the second locking block.

[0010] According to another embodiment of the present invention, the sealing mechanism is further included as a sealing ring.

[0011] According to another embodiment of the present invention, the second sealing mechanism is further comprising a sealing ring.

[0012] According to another embodiment of the present invention, the outer wall of the outer casing is further provided with a hook.

[0013] The beneficial effects of this utility model are that by welding the wire to the aluminum busbar, the space occupied is reduced. It also allows for easier installation on vehicles and reduces costs. The outer and inner shells better protect the connection points between the wire and the aluminum busbar, and the structure is more stable and reliable. Attached Figure Description
