Further, the anti-rotation structure is anti-rotation salient point, and the groove is semi-spherical grooves, when being pressed into shell, salient point meeting Get into inside insulator, prevent insulator from rotating, so as to ensure the anti-rotation performance of inner wire.

Further, the anti-rotation structure includes support ring and screw thread salient point, and the support ring is vertical with contacting end surface Set and extend to outside contact head；The screw thread salient point bottom imbedding and contact end surface is simultaneously rotatably connected with contact head, The screw thread salient point is arranged in support ring, bottom surface offers cross recess, and perforative hole slot is offered inside the contact head；Institute State insulator and set with the corresponding position of anti-rotation structure fluted, the groove includes annular slot and thread groove, described Support ring is connected together with annular slot, and the screw thread salient point is screwed with thread groove to be connected.This anti-rotation structure can play anti- Only insulator rotates and prevents the dual fail-safe effect that contact head is deviate from, and being added compared to simple anti-rotation salient point prevents contact head from taking off The function of going out.During assembling, screw thread salient point is screwed in by thread groove by hole slot while support ring is embedded in annular slot.

The beneficial effects of the utility model are：

（1）, contact head press-in shell when, insulator will not be caused to damage, structure is reliable；

（2）, anti-rotation structure design can prevent insulator rotate, ensure radio frequency connector anti-rotation performance；

（3）, can strengthen the connective stability of contact head, prevent plug when contact head deviate from.
