Description

Optical fiber connector Technical Field The invention relates to the field of communication devices, in particular to an optical fiber connector. Background In particular, for small LC connectors, the conventional optical fiber connector is generally configured to be mated with an adapter by integrally forming a push-on type engagement portion having a spring arm. The bending part of the spring arm mainly realizes rebound through the deformation of materials, and when the drawing structure is adopted to realize the bending unlocking of the spring arm, the drawing force is larger due to the participation of the deformation component, and the connector is unsmooth in drawing action. Or the tail sleeve of the tail part is pulled to directly drive the elastic arm to push down in the prior art, the structure directly drives the elastic arm to push down through the tail sleeve to push down, the acting force required by pushing down the elastic arm is large under small-amplitude action, the unlocking operation is difficult, the excessive pulling force is easy to damage a clamping part or an adapter, and the long-term use can lead to the reduction of the connection stability of the connector and the adapter. Because the pulling force is larger and is not easy to unlock, the excessive pulling force is easy to cause damage to the clamping part or the adapter, and the connection is easy to be unstable after long-term use. Still other solutions require the spring arm to rotate or utilize other structures to make the spring arm rotate, and the rotating structure requires the use of parts to deform themselves, which is fragile, especially for plastic parts.
