| 摘要 |
An optical-fiber cable coupler for coupling an optical-fiber cable to an endoscope light source includes a heat conducting member which is in heat conductive contact with the end of a sheath of the light source end of an optical-fiber cable so that thermal energy may be drawn from the sheath to the member and flow to a heat sink during illumination of the cable by the light source. In a first embodiment, the heat conducting member is a finger of a collet which is drawn into contact with the sheath by a collet nut. In a second embodiment, the heat conducting member is a resilient, sheath-supporting finger.
