Description

Technical Field

[0001] This utility model belongs to the field of new energy electric vehicles, and specifically relates to a 90° charging socket. Background Technology

[0002] Traditional car charging sockets typically have cables exiting directly from the rear, requiring a large bending radius during assembly, which limits the overall wiring harness layout and wastes interior space. In contrast, the national standard 90° angle socket allows cables to exit from the side, eliminating the need for bending, saving space and facilitating layout. Furthermore, current demands for integrated and miniaturized charging sockets are high, and the national standard 90° angle socket optimizes design to reduce size and meet these trends. In addition, traditional bent sockets suffer from inconvenient assembly and low maintenance efficiency; for example, terminal installation and cable handling require turning, and repairs are difficult after damage.
