Description

Technical Field

[0001] This invention relates to the field of highly integrated connector design technology, and more particularly to integrated connection devices with high integration. Background Technology

[0002] With the continuous development of the automotive industry, battery packs, as a core component of automobiles, are also constantly being improved and perfected. However, existing battery pack technologies still have certain shortcomings, such as the large number of connecting components within the battery pack, including the MSD, junction box positive, junction box negative, heating connector, and signal connector, all of which are individual, independent units (e.g., Figure 1 As shown), the components are separated and work independently. This results in a large space occupied by directly connected devices within the battery pack, leading to higher manufacturing costs. There are also significant issues with the tightness and safety of the connections. In particular, the numerous wire harnesses during use often create great difficulties for wiring. Therefore, further improvements are needed. Summary of the Invention
