Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a connecting copper busbar for a junction box. Background Art

[0002] In the new energy vehicle sector, an adapter box, often called a new energy vehicle charging monitoring adapter box or electric vehicle tester, is a device that connects the charging station and the electric vehicle. Adapter boxes will become more integrated, integrating more charging monitoring, management, and protection functions. This will not only improve the overall performance and reliability of the device, but also reduce user operation difficulty and costs. Therefore, the integrated circuit board within the existing adapter box needs to collect voltage and current signals from the copper busbar during the charging process.

[0003] Different manufacturers have different internal layouts for adapter boxes. The circuitry used to collect electrical signals from the copper busbars in existing adapter boxes is complex, resulting in larger internal components. However, some manufacturers are now seeking to miniaturize adapter boxes to accommodate the needs of different vehicle designs. Changing the internal power supply structure is a key research area for miniaturization. Summary of the Invention
