Description

A kind of fiber optic connector assembly
Technical field
The present invention relates to the fiber optic connector assembly for optical signal transmission.
Background technology
In optical communication field, DLC plug is as a kind of common LC connector, and DLC plug widely uses in the world, but DLC plug self-protection effect is poor, cannot be applied directly in the severe applied environment such as outdoor, prior art increases protective casing outside DLC plug.The existing joints of optical fibre are disclosed in Chinese patent CN201262657Y " fiber optic cable connector for accessing equipment ", comprise the housing that front end is provided with clamp, the rear end of housing is connected with afterbody cable lock locking structure by crimping swivel nut, be pressed with to bond between crimping swivel nut and optical cable and overlap, bonding cover is solidified into one-piece construction with the fiber optic protection layer of optical cable by solid blob of viscose, clamp is provided with modular plug, latching segment clamp conciliate by the lock portion clamp arranged before and after clamp comprises, lock portion clamp has the locking arm of end elasticity overhanging backwards, locking arm is provided with lock dog, separate latching segment clamp and there is the end unlocking arm that elasticity overhangs 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 is separated, being unlocked by pressing arm, unlocking arm presses down locking arm, lock dog can be made to 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), namely first connect the housing of (separation) plug, socket, then connect (separation) plug, socket; Although the protection method be threaded is relatively simple for structure, connect lower with the efficiency be separated, and this connector is when screwing screw thread butt-joint socket, torsional forces controls improper being easy to and damages connector, is not easy to construction and safeguards.
Summary of the invention
The object of the present invention is to provide a kind of connection, fiber optic connector assembly that separation efficiency is higher.
In order to solve the problem, in the present invention, a kind of technical scheme of fiber optic connector assembly is:
A kind of fiber optic connector assembly, comprise plug and socket, socket comprises Socket casing, plug comprises the plug casing being provided with clamp, the locking clamp subdivision arranged before and after clamp comprises conciliates pintle hook lock subdivision, locking clamp subdivision has locking arm, unlock latching portion and there is the end unlocking arm that elasticity overhangs above locking arm, the front end sleeve of described plug casing is equipped with can the solution lock tube of guiding movement along the longitudinal direction, the front end jacket wall of solution lock tube is provided with radial direction through hole, the front end of plug casing is provided with from the inside to the outside by the locking barb passed in described radial direction through hole for being clasped with Socket casing, the front end of locking barb is provided with housing and unlocks spigot surface, when the front side hole wall of described radial direction through hole is used for moving after separating lock tube and described housing unlock spigot surface and slide and push up press fit and radially move inwardly to oppress described locking barb, described unlocking arm is provided with clamp and unlocks spigot surface, described unblock put be provided with for separate move after lock tube time and described clamp unlock spigot surface and slide and push up press fit to oppress the unlocking arm fit structure of unlocking arm towards locking arm movement.
Push up between described solution lock tube and plug casing and be provided with outer spring.
Described locking barb rear end is used for coordinating with the rear side hole wall block of described radial direction through hole separates lock tube move the limit forward to limit.
The left and right sides of the end of described unlocking arm is provided with solution lock dog, the front end face shape of each solution lock dog is recess cambered surface forward, clamp described in described cambered surface is formed unlocks spigot surface, described unlocking arm fit structure comprise be arranged on described solution lock tube jacket wall inside on the projection corresponding with each solution lock dog.
Described unblock latching portion is provided with the left and right groove installed for corresponding two modular plug, the rear end unlocking latching portion is provided with the upper and lower tile plate of the confession corresponding inner spring suit that axis extends along the longitudinal direction.
Beneficial effect of the present invention is: when plug, socket grafting, and plug casing, solution lock tube, clamp are all inserted in Socket casing, and the locking clamp subdivision of clamp and socket are locked, and the locking barb simultaneously on plug casing is snapped on Socket casing, at needs plug, when socket is separated, mobile solution lock tube backwards, unlock the front side hole wall that puts radial direction through hole and the housing of locking barb front end to unlock spigot surface and slide and push up press fit and lock barb radially move inwardly to oppress, thus make locking barb deviate to realize plug casing by Socket casing, the unblock of Socket casing, unlock the unlocking arm fit structure that puts and clamp to unlock spigot surface and slide and push up press fit and move towards locking arm to oppress unlocking arm simultaneously, unlocking arm presses down locking arm thus realizes clamp and unlocks, this also just means plug casing, the connection of Socket casing be separated can with clamp, the connection of socket is carried out with being separated simultaneously, improve the connection of fiber optic connector assembly, separation efficiency.
