DEVICE FOR HEATING SHRINKABLE TUBE FOR MASS-PRODUCTION ESPECIALLY FOR ELECTRICAL, ELECTRONIC, AND COMMUNICATION ENGINEERING

摘要

PROBLEM TO BE SOLVED: To adjust thermal energy beams toward one cable and a tube to be thermally shrunk relatively easily and accurately by providing a laser beam heat source as a heat source. SOLUTION: A device 2 for heating the shrinkable tube for mass-production of the cable of electrical, electronic, and communication engineering is mainly constituted of a laser beam heat source 1. The laser beams 2 that are relatively strongly turned into beams of the device 2 are directed toward a shrinkable tube 6 especially with characters that slides without being adhered to an electrical cable 5 via a mirror 3 being formed especially on a double convex surface by so called CO2 laser. A reflection mirror 7 is formed especially in an obtuse angle or a concave surface, thus indirectly heating a surrounding surface region 8 that is indirectly subjected to the laser beams 2 for generating shrinkage heat with the heat energy of laser beams that are formed into corresponding beams.
