Optical fiber coating removal device

摘要

Provided is an optical fiber coating removal device capable of carrying out coating removal favorably and decreasing the tensile force required for coating removal without there being any problems due to the ingress of water. In the optical fiber coating removal device (11), an optical fiber securing unit (13) is separated from a coating removal device body (12) in a state in which a coating (1b) is cut and heated by a coating removal unit (31), and a glass fiber (1a) is thus withdrawn from the coating (1b). The coating removal unit (31) is provided with a heater supporting member (43) on which a heater (42) is mounted. The heater supporting member (43) is received in a receiving recess (51) formed in a housing (12a). An insulation space (55) is formed between the receiving recess (51) and the heater supporting member (43). A side surface of the heater supporting member (43) comes into contact with the internal surface of a sidewall (51b) of the receiving recess (51) by way of a lateral rib (61) formed in the heater supporting member (43), to seal the insulation space (55).
