1 A wall through hole 2 is provided in the partition wall 1, and the wall through hole 2 has a large diameter hole 2A opening on the high pressure side, a small diameter hole 2B opening on the low pressure side, and a boundary between the two holes 2A and 2B. The large diameter hole 2 of the stepped wall through hole 2 is formed as a stepped wall through hole 2 in which a stepped wall 2C exists.
A partition block 3 is housed in A, with one end surface locked to the stepped portion 2C and the other end surface adjacent to the high-pressure side wall surface of the partition wall 1, and a photoconductor 8 is mounted in the center of the partition block 3. A receptacle 10 is attached to the one end surface of the partition block 3 with its optical axis aligned with the photoconductor 8, and between the partition block 3 and the partition wall 1. O-rings 4 and 5 are interposed therebetween, and a presser ring 6 is disposed on the high-pressure side wall surface of the partition wall 1 and is arranged concentrically with the large diameter hole 2A to press the other end surface of the partition block 3. ring 6
is fixed to the partition wall 1 by tightening bolts 7, and the flange portion of the connector housing 15 is brought into contact with the other end surface of the partition block 3 and fixed by tightening bolts 16, so that the flange surface of the connector housing 15 and the partition An O-ring 18 is interposed between the connector housing 15 and the other end surface of the block 3, and a ferrule insertion hole 17 with a stepped portion 17A is provided in the center of the connector housing 15. A large diameter hole 17B opening on the side of contact with the partition block 3 and the large diameter hole 1
A connector ferrule 19 with a step 19A is accommodated in the ferrule insertion hole 17, and a small diameter hole 17C is provided continuously through the step 17A. A spring 2 is disposed between the step portion 17A of the ferrule insertion hole 17 and the step portion 19A of the connector ferrule 19 within the large diameter hole portion 17B of the connector ferrule 17.
1 is interposed therebetween, and the stepped portion 19A of the connector ferrule 19 comes into contact with the inner surface on the entrance side of the large diameter hole portion 17B of the ferrule insertion hole 17, thereby preventing the connector ferrule 19 from coming off. The ring 20 is screwed together, the end of the optical cable 22 is inserted into the connector housing 15, and the optical fiber core 23 led out from the end of the optical cable 22 is inserted into the connector ferrule 1.
9 and is supported through the connector ferrule 1.
9 and the photoconductor 8 of the partition block 3
A pressure-resistant optical cable bulkhead penetrating portion, characterized in that a molded portion 24 is provided in alignment with an embedded end surface of the connector housing 15 and the optical cable 22.
