<p>PURPOSE:To provide a structure in which a sufficiently strong anchoring force can be obtained for the part of inorganic insulated cable composed of a thin metallic sheath passed through a hole formed through a fixing plate for sealing and the cable can easily be sealed and which can be reduced in manufacturing cost. CONSTITUTION:A fixing metallic ring 6 is united to the metallic sheath of a mineral insulated cable 1 passed through the hole 2a of a fixing plate 2 for sealing by blazing 9 and, at the same time, a step section 2b and enlarged section 2c are formed in the hole 2a and a fixing metallic ring is put in the enlarged section 2c and pressed against the section 2b. A metallic contact seal can be formed by tapering the pressing section. When the enlarged section 2c is threaded and a nut 5 is engaged with the threaded section, the metallic ring can be fixed reliably and pressed reliably against the section 2b. The 3 and 3 in the figure represent final seals formed of an epoxy resin.</p> |
