Guide sleeve for light waveguide plug devices utilizing a sliding sleeve for wiping pin shaped bodies

摘要

An improved guide sleeve for receiving a pin shaped body or plug pin containing a lightwave guide to form a lightwave guide plug connection characterized by the guide sleeve having a cylindrical acceptance opening extending to at least one end for receiving the pin and terminating in an enlarged diameter cylindrical portion coaxial with the acceptance opening, and a sliding sleeve of a synthetic plastic material such as polytetrafluoroethylene being disposed in the enlarged diameter portion and having a decreasing inner diameter forming a lip adjacent one end of the sliding sleeve which one end is adjacent the acceptance opening. Thus when a pin-shaped body is inserted into the guide sleeve, the outer surface of the body will be wiped by the lip to limit or prevent the introduction of dirt or other substances into the interior of the guide sleeve.
