Abstract: This application provides a pre-connector and a communications device. The pre-connector includes a connector component and an outdoor component. The connector component includes a ferrule base and a ferrule that is slidable relative to the ferrule base. The ferrule base is configured to fasten the optical cable, and the ferrule is connected to an optical fiber that is of the optical cable and that is inserted into the ferrule base. In this way, the optical fiber can be connected to the communications device by using the ferrule. The outdoor component includes: a spindle that is sleeved on the ferrule base and that is fastened to the ferrule base; and a handle sleeve sleeved on the spindle. The outdoor component is used as a connecting piece to be detachably fastened and connected to the communications device, so as to provide a locking force used when the communications device is connected.
