Abstract: An on-site hot-melt quick connector for optical fibers comprises a plug housing, a ferrule, an optical fiber telescopic protective tube, a tail end cover, a pressure welding protective tail handle and a compression ring. A front baffle ring is mounted in the plug housing and a rear baffle ring is mounted in the tail end cover. The ferrule and the optical fiber telescopic protective tube are positioned between the front baffle ring and the rear baffle ring and can move in the axial direction. As the quick connector for optical fibers of the invention has a definite space for movement in the axial direction, the optical fibers themselves can move along with the plugging action during butting, avoiding the bending of the optical fibers caused as they are unable to move, thus guaranteeing the transmission quality of the optical signals. The service life of the quick connector is also guaranteed.

Abstract: A thermal conductive member is mounted on a heat generating object. An air cooling member is attached to the thermal conductive member for radiating heat into air. A liquid cooling member is removably attached to the thermal conductive member for absorbing heat from the thermal conductive member.

The heat radiating member serves to radiate the thermal energy into the air from a larger surface area. The heat generating object can in this manner be cooled down even without the liquid cooling member.
