Description

Technical Field

[0001] This utility model relates to conductive components and electrical connection assemblies. Background Technology

[0002] Traditionally, charging docks for new energy vehicles typically include terminals and wires electrically connected to the terminals. To improve current carrying capacity, aluminum busbars are increasingly being used instead of wires for power transmission. The terminals are usually copper terminals, and in one existing technology, the copper terminals are welded to the aluminum busbar. The inventors of this invention have discovered that because the aluminum busbar is compressed by the copper terminals, metal wires are generated during the welding process between the aluminum busbar and the copper terminals. These exposed metal wires pose electrical safety hazards and are also unsightly. Utility Model Content
