Description

Technical Field

[0002] With the continuous inclination of national policies towards new energy vehicles and the development of the industry itself, new energy vehicles are being accepted and sought after by more and more consumers. However, the problems of difficulty in charging, slow charging, and concerns about the range of the vehicle are becoming more prominent. In terms of on-board charging, in addition to the problem of slow charging, there are also problems of incompatibility of charging standards and basic charging equipment in each country and region. At this time, the charging adapter that meets the mutual conversion between different standards can not only use its own charging network for charging, but also use charging facilities that meet the national standards of other countries or regions for charging. This move has greatly enriched the charging network, further improved the charging convenience of car owners, enriched the charging outlets, and allowed car owners to charge more freely and casually. More importantly, the release of the charging adapter has further strengthened consumers' confidence in new energy vehicles, making the concept of green, environmentally friendly and people-friendly green travel deeply rooted in the hearts of the people. At the same time, the intelligentization, electrification, and high reliability requirements of new energy vehicle products are getting higher and higher. Therefore, the self-perception and judgment of a single system need to be more active and intelligent. Among them, new energy adapters can realize mutual charging between different charging standards, and different charging standards define different power terminal positions and different PIN sequences. In order to realize the connection between the power terminals, it is necessary to realize conductive connection through transfer copper busbars between different power terminals. However, in existing new energy adapters, how to reasonably layout the structure of the transfer copper busbar to optimize the size of the adapter and have good mechanical and electrical properties has always been a technical problem that needs to be solved urgently in this field.
