Description
Technical field
The present invention relates to the optical fiber connector plug for optical signal transmission.
Background technology
In optical communication field, DLC plug is as a kind of common LC joints of optical fibre, and DLC plug is widely used the most in the world, but DLC plug self-protection effect is poor, cannot be applied directly in the severe applied environments such as outdoor, prior art is increase protective casing outside DLC plug.nullThe existing joints of optical fibre such as Chinese patent CN201262657Y is disclosed " fiber optic cable connector for accessing equipment "，The housing of clamp is installed including front end，It is provided with restriction clamp on housing and moves the position limiting structure of the limit in advance，The rear end of housing is installed with tail accessory，Tail accessory includes attaching nut and the tight big envelope of cable lock，Modular plug is installed on clamp，Clamp includes that latching segment clamp conciliate by the lock portion clamp front and back arranged，Lock portion clamp has the end elastic locking arm overhang backwards，Lock dog it is provided with on locking arm，Solve latching segment clamp and there is end elastic unlocking arm overhang above locking arm rear end，At plug、During socket grafting，Lock dog on locking arm is locked with the locked groove on socket and is coordinated，At needs plug、When socket separates，Being unlocked by pressing arm，Locking arm is pressed under unlocking arm，Lock dog can be made to be deviate from by corresponding locked groove，Realize unlocking.The front end turning set of housing is equipped with attaching nut.Plug, socket need many more manipulations when connecting (separation), the most first connect (separation) plug, the housing of socket, then connect (separation) plug, socket；Although threaded protection method is relatively simple for structure, but connecting inefficient with separate, and this adapter is when screwing screw thread butt-joint socket, torsional forces controls improper being easy to and damages adapter, is not easy to construction and safeguards；It addition, housing is integrally fixed on cable, it is impossible to freely change, as in plug, certain parts damages then needs to change whole cable, it is not easy to safeguard, there is more serious wasting phenomenon.
Summary of the invention
It is an object of the invention to provide a kind of connection, separation efficiency higher, and load and unload optical fiber connector plug easy to maintenance.
In order to solve the problems referred to above, the technical scheme is that
nullA kind of optical fiber connector plug，Including the plug casing being provided with clamp and the tail accessory installed for corresponding cable seal，Clamp includes that the locking clamp subdivision front and back arranged conciliates pintle hook lock subdivision，Locking clamp subdivision has locking arm，Unlock latching portion and there is end elastic unlocking arm overhang above locking arm，Plug casing rear end spinning is on described tail accessory，Unlock and be top-loaded with inner spring between latching portion rear end and tail accessory，It is provided with on the housing wall of plug casing and unlocks latching portion block and coordinate and unlock latching portion move the limited step of the limit forward to limit，The front end sleeve of described plug casing is equipped with can the solution lock tube of guiding movement along the longitudinal direction，Solve and be provided with radial direction through hole on the front end jacket wall of lock tube，The front end of plug casing is provided with from the inside to the outside by passing in described radial direction through hole for the locking barb with respective socket housing resilient snap fitment，Locking barb rear end moves the limit for coordinating with the rear side hole wall block of described radial direction through hole forward with restriction solution lock tube，The front end of locking barb is provided with housing and unlocks spigot surface，Unlock spigot surface slip top press-fit when the front side hole wall of described radial direction through hole is for moving after solving lock tube to move radially inward to oppress described locking barb with described housing，It is provided with clamp on described unlocking arm and unlocks spigot surface，Described unblock puts and unlocks the unlocking arm fit structure that spigot surface slip top press-fit is moved towards locking arm with compressing unlocking arm when being provided with for moving after solving lock tube with described clamp.
Between described solution lock tube and plug casing, top is provided with outer spring.
Solution lock dog it is provided with on the left and right sides of the end of described unlocking arm, each front end face shape solving lock dog is recess cambered surface forward, the described clamp described in cambered surface composition unlocks spigot surface, and described unlocking arm fit structure includes the projection corresponding with each solution lock dog being arranged on inside the jacket wall of described solution lock tube.
Being provided with the left and right groove installed for corresponding two modular plug on described unblock latching portion, the rear end unlocking latching portion is provided with the upper and lower tile plate of the described inner spring suit that axis extends along the longitudinal direction.
Described tail accessory includes cable seal lock sleeve and is arranged at the attaching nut on front side of cable seal lock sleeve, attaching nut is threadeded with plug casing front end, threaded with cable seal lock sleeve in the rear end of attaching nut, described tail accessory also includes that be arranged in described plug casing with corresponding wire covering fixed bonding bonding set, padding between bonding set and attaching nut equipped with back-up ring, top, described inner spring rear end is contained on described back-up ring.
When the invention have the benefit that plug, socket grafting, plug casing, solution lock tube, clamp are inserted in the Socket casing of socket, and the locking clamp subdivision of clamp is locked with socket, and the locking barb on plug casing is snapped on Socket casing simultaneously；At needs plug, when socket separates, mobile solution lock tube backwards, the housing of front side hole wall and locking barb front end that unblock puts radial direction through hole unlocks spigot surface slip top press-fit and moves radially inward to oppress locking barb, so that locking barb is realized plug casing by abjection on Socket casing, the unblock of Socket casing, unlock the unlocking arm fit structure put to move towards locking arm with compressing unlocking arm with clamp unblock spigot surface slip top press-fit simultaneously, press locking arm under unlocking arm thus realize clamp and unlock, this also implies that plug casing, the connection of Socket casing is with separate can be with clamp, the connection of socket is carried out with separating simultaneously, improve the connection of fiber optic connector assembly, separation efficiency；When assembling the most at the scene, clamp is assemblied on plug casing, the limited step on plug casing is utilized to limit the advanced mobile limit of clamp, then by plug casing spinning on tail accessory, the most again solution lock tube is sleeved on plug casing, locking in the radial perforation that barb is put by unblock on plug casing is made to pass, the rear end of locking barb is possible to prevent to solve lock tube and is deviate from by plug casing, thus achieve the assembling process of plug, plug can be with field fabrication, in plug, each parts are prone to dismounting, and it is the most convenient to repair.
