Heater for heating heat shrinkable tube

摘要

A heater for heating a heat shrinkable tube fitted over an elongated member includes a base having an elongated support plate of a thermally conductive material for supporting the heat shrinkable tube on one surface thereof. The support plate has a heating portion at a central portion thereof. The heat shrinkable tube is adapted to be placed on the support plate along a length thereof with the opposite end portions of the tube disposed outwardly of the opposite ends of the heating portion, respectively. A heating element is disposed in contact with the other surface of the support portion and disposed in registry with the heating portion. The heating element is operable to first heat the heating portion and then the opposite end portions of the support portion extending outwardly from the opposite ends of the heating portion through heat transfer, so that the heat shrinkable tube is heat shrunk from its central portion toward the opposite ends thereof.
