PURPOSE:To connect an optical fiber to an optical fiber with superior weatherability as keeping water proof and light shielding for the optical fiber deriving port of insulator with and built-in optical fiber the optical fiber. CONSTITUTION:The optical fiber 20 is directly inserted to the inside by mounting a light shielding airtight case 30 on the terminal part of the insulator 10 with built-in optical fiber in which the optical fiber 20 is pierced through an insulator main body 11, and the optical fiber 20 is connected to an optical fiber 22 with reinforcing jacket. An sealing case 40 is mounted on the light shielding airtight case 30, and the optical fiber 22 with reinforcing jacket is directly inserted to the inside, and the optical fiber 22 with reinforcing jacket is connected to an optical fiber 23 with weatherability. The optical fiber 23 with weatherability derived from the sealing case 40 is fixed on the sealing case 40. |
