Specific implementation mode
The present invention is described in detail below in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of direct insertion optical fiber connectors, including plug 1 and socket 2；Plug 1
Including plug casing 11, coupling nut 12, spring 13, trim ring 15 and clamp spring 16, plug casing 11 is the internal circle with cavity
The head end periphery of cylinder body shape, plug casing 11 is provided with arc groove 111 and annular convex platform 1；12 inner ring surface of coupling nut
On be provided with annular convex platform 2 121 and inclined-plane 122, coupling nut 12 is connected through a screw thread with plug casing 11, annular convex platform two
121 and annular convex platform 1 abut against；It is equipped in cavity between the tail end and the tail end of plug casing 11 of coupling nut 12
Spring 13,11 tail end periphery of plug casing be equipped with groove 1, clamp spring 16 is installed in groove 1, spring 13 with
Trim ring 15 is installed, clamp spring 16 coordinates trim ring 15 by 13 axially position of spring between clamp spring 16；
