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 joints of optical fibre housing unit, 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 joints of optical fibre housing unit of the present invention is by the following technical solutions: locking thread joints of optical fibre housing unit, comprising is separately plug casing parts and the Socket casing parts of inserted terminal with front end, plug casing parts comprise plug casing and coupling nut, Socket casing parts comprise Socket casing, be provided with for making the two plug together the rear spin-ended spin-ended location structure coordinated between plug casing with Socket casing, 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 joints of optical fibre housing unit 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.

Embodiment
The embodiment of locking thread joints of optical fibre housing unit, as shown in figs 1-9, this locking thread joints of optical fibre housing unit comprises plug casing parts and Socket casing parts, plug casing parts and Socket casing parts are inserted terminal separately with front end, plug casing parts comprise plug casing, and Socket casing parts comprise Socket casing 17.
Plug casing is provided with coupling nut 12 and loose-proof sleeve 13.Plug casing comprises protheca 14 and rear cover 15, and the front portion of protheca 14 is provided with positioning key 16, and positioning key 16 realizes location between plug casing and Socket casing 17 and spline for coordinating with the positioning spline on Socket casing 17.The rear portion of protheca 14 is provided with internal thread, simultaneously, the jacket wall at its rear portion also offers featherway 18, the afterbody side of featherway 18 is provided with gap structure 19, this gap structure 19 makes the rear end face of protheca 14 defines a step surface in the side of featherway 18, and this step surface can use as the structure of other corresponding component of block.Rear cover 15 Screw assembly protheca 14 afterbody and be fixed together with protheca 14, in addition, its jacket wall is also provided with outer convex edge 20 structure.
The rotating anticreep of coupling nut 12 is assemblied on the protheca 14 of plug casing, and its mounting structure is prior art, and it will not go into details herein.The protheca 14 that loose-proof sleeve 13 spline is assemblied in plug casing can move along the longitudinal direction, the rear end of coupling nut 12 is adjacent with the front end of loose-proof sleeve, wherein be provided with the spin-ended structure that can plug together vertically and be separated between the rear end of coupling nut 12 and the front end of loose-proof sleeve 13, in the present embodiment, the spin-ended structure specifically keyway 21 set by the rear end of coupling nut 12 and the plug-in type key 22 set by loose-proof sleeve 13 front end is formed, the front end place of loose-proof sleeve is provided with the feather key 23 coordinated that to lead with the featherway 18 on protheca, loose-proof sleeve to be spin-endedly assemblied on plug casing with coordinating of featherway by feather key 23.
In the process used, when the locked coupling nut 12 of needs, plug-in type key 22 is inserted in the corresponding keyway on coupling nut 12, when needs release connection nut 12, loose-proof sleeve 13 is moved backward, plug-in type key 22 is made to depart from slot on coupling nut 12, when needs are significantly rotationally connected nut 12, then pull back loose-proof sleeve 13, feather key 23 is hung on the above-mentioned step surface of protheca rear end, in order to prevent loose-proof sleeve automatic rollback, also biasing springs is top-loaded with between plug casing and loose-proof sleeve, biasing springs urged forward coupling nut, in the present embodiment, what biasing springs specifically adopted is volute spring.
