Description
Technical Field
The invention relates to the technical field of optical fiber connection, in particular to a push clamp and an optical fiber quick connector assembly.
Background
At present, with the rapid development of optical fiber communication technology, the PON access technology has become the most important solution for the global FTTH (fiber to the home) popularization. For the access installation of the FTTH, the optical fiber quick connector assembly has become the optimal selection scheme for the access of the FTTH at present due to the advantages of convenient installation, rapidness, high efficiency and the like. Straight-through and pre-buried types are common in existing fiber optic quick connector assemblies. The embedded type quick connector assembly is characterized in that an optical fiber is embedded in an inner hole of a ceramic ferrule, one end of the optical fiber and the ceramic ferrule form an end head which is in butt joint with a normal connector after grinding and polishing, the other end of the optical fiber is exposed for a certain length and the end surface is ensured to be flat, then the exposed end optical fiber is installed in a V-shaped groove, half of the V-shaped groove is made of organic materials or metal materials, the V-shaped groove is provided with a corresponding optical fiber pressing and sticking block which is used for locking and pressing the butt joint of an external optical fiber and the embedded optical fiber, matching gel is preset in the V-shaped groove in advance during.
When the embedded optical fiber quick connector assembly is used for field installation, after the external optical fiber and the embedded optical fiber are completely butted, the optical fiber pressing block needs to be pushed to a locking and pressing butt joint state through the pushing clamp. A conventional push clip is shown in fig. 8, which has a finger-engaging long wing 101, because the clip point 103 is stationary, it needs to be deformed at the thinner deformation region 102 for clipping into the corresponding slot of the latch. When the connector is in work, the pushing clamp is slightly bent and deformed along the deformation area 102, the two walls are pinched when the clamping point 103 can be smoothly clamped into the guide groove, the initial state of the pushing clamp is recovered, then the long wing 101 is pushed by fingers to enable the longest edge to be aligned with the front end of the connector body, and then the pushing clamp is clamped down.
Since the push clamp needs to be deformed for multiple times during working, it is necessary that the deformed region is a thinner structure relative to other regions, otherwise, the deformed region is too thick, so that the push clamp cannot be deformed normally. However, the deformation area is very thin, so that the whole structure of the push clamp is unstable and failure is easy to occur; on the other hand, in order to facilitate stress and positioning, the push clamp is provided with a long wing structure which is attached to fingers, but the volume of the push clamp is greatly increased. Meanwhile, the push clamp adopting the traditional structure can not judge whether the lock catch is in place after operation, and further determines whether the lock core assembly is locked and fastened at the butt joint point of the embedded optical fiber and the external optical fiber; and the operation of the traditional push clamp is complex and the convenience is not strong.
