The explanation of embodiment is not intended to limit the scope of protection of the present invention.
It as shown in Figure 1 to Figure 2, is the structural schematic diagram of the anti-rotation structure of electric power connector provided by the invention.It is described
The anti-rotation structure of electric power connector includes an inner sleeve 10, a defeated spool 20 being set on the inner sleeve 10, a use
In the nut 30 for connecting the inner sleeve 10 and defeated spool 20 and one for fixing the card of the inner sleeve 10 and nut 30
Ring 40.It is envisioned that the electric power connector further includes other some functional modules, and such as female needle, the zero of fixed mother's needle
Component, sealing structure, bundle conductor etc., which is a technique known to those skilled in the art, is no longer described in detail one by one herein.
The inner sleeve 10 includes an end 11, the locating piece on multiple outer peripheral edges for being arranged at intervals on the end 11
12, the end 11 is arranged in sealing 13 between the free end and locating piece 12 of the end 11 and one
The first card slot 14 on outer peripheral edge.Angle in multiple locating pieces 12 between the adjacent locating piece 12 of any two is equal.
The central angle of each locating piece 12 is equal in multiple locating pieces 12.The locating piece 12 is along the straight of the inner sleeve 10
