The invention relates to an anti-loose optical fiber connector plug shell and an anti-loose optical fiber connector plug. The anti-loose fiber optic connector plug housing includes a front sleeve and a rear sleeve; the connecting nut sleeve is set on the outside of the front sleeve; the locking housing is slid and guided along the front sleeve axis and assembled on the outside of the front sleeve or the rear sleeve; There is a locking position in the sliding stroke, and the mating surface of the locking housing and the connecting nut is provided with a concave-convex matching structure to realize anti-rotation; the locking housing has an unlocking position, and the locking housing is unlocked when it is in the unlocking position. There is a locking shell anti-rotation structure between the rear sleeve and the locking shell; a locking shell is set between the rear sleeve and the locking shell to press the locking shell towards the connecting nut to lock the locking shell Spring held in the locked position. The present invention locks the connecting nut through the locking shell, the structure of the locking shell is relatively simple, and it is more reliable to stop the rotation through the circumferential mating surface of the sleeve, which can prevent the locking nut from loosening under vibration From affecting the butt joint of the fiber.
Description
technical field [0001] The invention relates to an anti-loose optical fiber connector plug shell and an anti-loose optical fiber connector plug. Background technique [0002] FC fiber optic connector assembly is a common fiber optic connector assembly, the plug and socket in this connector assembly are connected together through a threaded connector. Because it is a standard connector, the FC fiber optic connector assembly has been widely used. The plug in the FC fiber optic connector assembly generally includes a front sleeve and a rear sleeve, and the ferrule is inserted into the front sleeve and the rear sleeve. The rear sleeves are connected together by threads, and the outer sleeve of the front sleeve is provided with a connecting nut connected with the socket, and the connecting nut is used for threaded connection with the socket. However, in some environments where there are factors such as vibration and shock, the plug and socket assembled together only by threads m...
