Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector technology, and in particular to a push-pull MPO connector unlocking lever. Background Technology

[0002] MPO connectors (Multi-fiber Push-On connectors) mainly consist of a male MPO connector (PIN guide pins) and a pre-connector (PIN guide hole). During use, the connector and the female MPO connector are mated and secured via an MPO adapter. The two guide pins of the connector align with the two holes of the pre-connector to ensure mating accuracy and create one-to-one fiber contact between the connector and the pre-connector, allowing optical signals to be transmitted from one connector to another. However, in existing connector structures, the tail sleeve must also function as an unlocking push-pull handle, necessitating modifications to the original connector's push-pull housing. Furthermore, the secure connection between the push-pull tail sleeve and the original connector's push-pull housing is unreliable due to the soft material of the tail sleeve, making it prone to detachment.
