Abstract
The invention relates to the field of optical connectors, in particular to a threaded looseness prevention optical fiber connector plug shell assembly. The threaded looseness prevention optical fiber connector plug shell assembly comprises a plug shell and a coupling nut. A looseness prevention sleeve is further assembled on the plug shell. The looseness prevention sleeve is assembled on the plug shell in a rotation-stopping mode and in the manner of capable of moving forwards and backwards and is located behind the coupling nut. A thrust spring is installed between the plug shell and the looseness prevention sleeve in an abutting mode and pushes forwards the looseness prevention sleeve. Rotation stopping structures which can be inserted in or separated from each other in the axial direction are arranged at the adjacent ends of the coupling nut and the looseness prevention sleeve. During use, the plug shell and a socket shell are matched in the manner of mutual rotation stopping, the looseness prevention sleeve is matched with the plug shell in the manner of standstill locking, and the coupling nut and the looseness prevention sleeve are matched in the manner of rotation stopping; accordingly, rotation stopping match between the coupling nut and the socket shell is achieved, and therefore the purpose of looseness prevention can be achieved. Through the threaded looseness prevention optical fiber connector plug shell assembly, the problems that an optical connector assembly in threaded connection is poor in looseness prevention performance and not easy to detach and maintain are solved.
Description
Technical field
The present invention relates to optical connector field, particularly relate to a kind of locking thread optical fiber connector plug housing parts.
Background technology
FC fiber optic connector assembly is a kind of very common fiber optic connector assembly.It is made up of plug and socket in correspondence with each other, is wherein be threaded connection between plug and socket.Plug specifically comprises protheca, rear cover, light contact pin and coupling nut, socket comprises Socket casing, Socket casing is provided with the external thread corresponding with coupling nut, when in use, be to be coordinated with the external thread on Socket casing by coupling nut and to realize plug and socket fixing between plug with socket.
Owing to being AN connector, FC optical connector assembly is obtained for and applies very widely in dual-use field, at some applicable situations, inevitably the factors such as vibratory impulse can be there is, once there is above-mentioned factor in environment for use, the plug be then only fixed together by coupling nut and socket are obviously extremely insecure, in prior art, in order to prevent loosening between plug and socket, mostly that the matching part of mode to plug and socket by adding screw thread glue is strengthened, this causes inconvenience with the unloading that is separated of socket then to plug, the maintenanceability of fiber optic connector assembly is made to become extreme difference.
Summary of the invention
The object of the present invention is to provide a kind of locking thread optical fiber connector plug housing parts, to solve the optical connector assembly anti-loosening property be threaded problem that is poor and not easily detachable maintaining.
In order to solve the problem, locking thread optical fiber connector plug housing parts of the present invention is by the following technical solutions: locking thread optical fiber connector plug housing parts, comprise plug casing and coupling nut, plug casing is also equipped with loose-proof sleeve, movably spin-endedly before and after loose-proof sleeve to be assemblied on plug casing and to be positioned at the rear place of coupling nut, biasing springs is top-loaded with between plug casing and loose-proof sleeve, biasing springs urged forward loose-proof sleeve, coupling nut is provided with the spin-ended structure that can plug together vertically and be separated with the locking abutting end place being placed on the two.
One in described loose-proof sleeve and plug casing is provided with featherway, and another is provided with the feather key corresponding with featherway, by described featherway with feather key is spin-ended coordinates between loose-proof sleeve with plug casing.
Described loose-proof sleeve is assemblied on the protheca of plug casing.
Described spline structure is point to be located at keyway on coupling nut and loose-proof sleeve and plug-in type key.
Plug-in type key is located at the front end place of loose-proof sleeve, and keyway is located on coupling nut.
Plug casing due to locking thread optical fiber connector plug housing parts of the present invention is equipped with loose-proof sleeve, movably spin-endedly before and after loose-proof sleeve to be assemblied on plug casing and to be positioned at the rear place of coupling nut, biasing springs is top-loaded with between plug casing and loose-proof sleeve, and coupling nut is provided with the spin-ended structure that can plug together vertically and be separated with the locking abutting end place being placed on the two, therefore, when in use, spin-endedly to coordinate mutually between plug casing with Socket casing, between loose-proof sleeve with plug casing, spline coordinates, spin-endedly between coupling nut with loose-proof sleeve to coordinate, just to achieve between coupling nut with Socket casing thus spin-ended coordinates, thus just can reach locking object, when needs detachable maintaining, only need to rear compression biasing springs, then being separated of plug and socket just equally can be realized to the common optical connector assembly be threaded, therefore, the invention solves the optical connector assembly anti-loosening property be threaded problem that is poor and not easily detachable maintaining.
