Abstract

The invention relates to an anti-loosening optical-fiber connector plug shell body and an anti-loosening optical-fiber connector plug. The anti-loosening optical-fiber connector plug shell body includes a front sleeve and a rear sleeve assembled together in a thread manner. A connection nut is arranged outside the front sleeve in a sleeving manner, and is used for thread connection with a socket.A locking shell body is assembled outside the rear sleeve in a sliding guiding manner. A connection nut rotation preventing structure is arranged between the connection nut and the locking shell body.The locking shell body has a locking position and an unlocking position in a moving stroke thereof. The locking shell body rotation preventing structure is arranged between the rear sleeve and the locking shell body. Springs are arranged between the rear sleeve and the locking shell body. Compared with arranging a notch at a thread section of the front sleeve to realize rotation preventing assembly of the locking shell body with the front sleeve and the rear sleeve, the embodiment of the invention arranges the locking shell body rotation preventing structure on the rear sleeve, cannot impactconnection of the front sleeve and the rear sleeve, and guarantees improvement of strength and reliability of the optical-fiber connector plug on the premise that an anti-loosening role can be played.

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, but in some environments where there are factors such as vibration and shock, it is not reliable to fix the plug and the socket together only through threaded connection. [0003] The Chinese invention patent with the authorized announcement number CN104503034B and the authorized announcement date of 2018.01.05 discloses a loose-proof optical fiber connector. The optical fiber connector includes a front sleeve and a rear sleeve, optical fibers and ceramic ferrules for inserting optical fibers. In the nest and the rear sleeve, the fro...
