Plug for optical fiber cables and socket part for such plugs

摘要

A plug for an optical fiber cable includes an elastic cover cap which is seated at a light exit side of the plug and has a base that is penetrated by the optical fiber cable during insertion into a socket part. The elastic cover cap serves as a sealing and protective element. Upon insertion of the plug into a socket part, the cover cap remains seated on the plug. In the course of plugging in, the cover cap is gripped by a step in a holding bore of the socket part and is displaced on the plug. In this process, the cover cap base is torn open and exposes a coupling surface of the optical fiber cable.
