ABSTRACT:
The invention relates to a plug pin for a light waveguide (LWG) which can be plugged in a pin bushing, comprising a core tube having a central aperture into which core the LWG can be inserted and which tube is enveloped by a sleeve made of a material which is softer than that of the core tube and which has a higher coefficient of thermal expansion. A plug connection which is low-loss in a large temperature range is obtained in that the wall thicknesses of the sleeve (3) and of the core tube (2) are proportioned so that the resulting coefficient of thermal expansion of the plug pin corresponds substantially to the value of the material of the pin bushing (4).
