The charging base grounding anti-rotation structure of the present embodiment has a sunken boss 22 inside the mounting base 21, and a polygonal mating portion 41 outside the grounding terminal 4. The polygonal mating portion 41 is engaged with the sunken boss 22 to realize the engagement of the grounding terminal 4, thereby achieving the purpose of convenient installation of the grounding terminal 4 and realizing the technical effect of efficient assembly.

[0026] In this embodiment, the matching portion 41 is a square structure, and the cavity of the sunken boss 22 in the mounting seat 21 is also a square structure. When the matching portion 41 fits with the cavity of the sunken boss 22, the grounding terminal 4 cannot rotate horizontally; when the insulating bracket 2 is connected to the socket body 1, the sunken boss 22 and the surface of the matching portion 41 are fitted and fixed to the socket body 1, and the grounding terminal 4 cannot move in the vertical direction; therefore, the installation of the grounding terminal 4 is realized, which is convenient and quick.

The charging seat grounding anti-rotation structure of this embodiment has a limiting slot 23 on the mounting seat 21, and the grounding spring clip 6 passes through the limiting slot 23 and is connected to the grounding terminal 4. The purpose of limiting the clamping portion 63 of the grounding spring clip 6 is achieved through the limiting slot 23, thereby achieving the technical effect of reliable contact and stable connection between the grounding spring clip 6 and the grounding terminal 4. Specifically:

[0029] The grounding spring 6 has a C-shaped body 61, the middle part of which is connected to the circuit board 5 via a connecting portion 62. A clamping portion 63 is provided inside the C-shaped body 61, and the clamping portion 63 passes through the limiting slot 23 and is clamped on both sides of the matching portion 41.
