A fiber optic connector plug

Abstract

The invention discloses an optical fiber connector plug which comprises a front sleeve, a back sleeve and a coupling nut. A movable ratchet wheel and a static ratchet wheel which are arranged front and back are sleeved with the front sleeve, the back end face of the static ratchet wheel is provided with a positioning which is in positioning and rotation stopping fit with the back sleeve, the front end face of the static ratchet wheel is provided with a ring of static ratchets, positioning keys matched with the coupling nut are arranged on the peripheral surface of the movable ratchet wheel, the back end face of the movable ratchet wheel is provided with a ring of movable ratchets meshed with the static ratchets, and the movable ratchets and the static ratchets are each provided with a large tooth surface and a small tooth surface with the different inclination angles. When the plug is in threaded connection with a socket, the coupling nut can drive the movable ratchet to rotate, and the static ratchet does not rotate; when the coupling nut rotates forwards to be locked, the rotation locking torque of a coupler is small; when the coupling nut rotates reversely to be loosened, the rotation loosening torque of the coupler is large; by mutually connecting the coupling nut with the movable ratchet and the static ratchet, the anti-loose purpose on threaded connection of the plug and the socket can be achieved.

Description

technical field [0001] The invention relates to the field of optical fiber connectors, in particular to an optical fiber connector plug. Background technique [0002] FC fiber optic connector is a common fiber optic connector, such as figure 1 As shown, it includes plug 1 and socket 2, and the plug and socket are connected by M8 thread. The plug 1 includes a front sleeve 12 , a rear sleeve 16 , an optical fiber contact and a connecting nut 15 , and the optical fiber contact includes a ceramic pin 11 , a flange 13 and a spring 14 . The outer side of the optical cable 19 is provided with a sheath 17 , the cable sheath of the optical cable is fixed on the rear sleeve 16 through a crimping sleeve 18 , and the optical fiber of the optical cable passes through the flange 13 and is connected to the rear end of the ceramic ferrule 11 . The socket 2 includes a socket housing, and the socket housing is provided with external threads corresponding to the connecting nut. When in use, ...
