Further, an optical cable 7 is inserted into the holding tube 5 from the other end. The outer sheath 8 of this optical cable is peeled off by a predetermined length at one end so that the fiber core wire 9 is exposed. Furthermore, this fiber core wire protrudes into the storage chamber 3. A holding piece 10 for holding the end of the fiber core wire 9 is housed in this housing chamber. Also, at one end of the containment chamber, the base 1
A cover 11 is provided to cover this accommodation chamber.
This cover has a luminous property and is made of, for example, a compound. A light emitting element or a light receiving element 12 is housed in the accommodation chamber 3 and arranged to optically face the fiber core wire 9, and its lead wire 13 is led out through the cover 11. There is. The fiber core wire 9 is held by a holding piece 10 so that it is always optically opposed to the light emitting element or the light receiving element 12. A plurality of movable claws 15, 1 are provided on the inner peripheral wall of the holding cylinder 5.
5 is provided, and this claw engages with the jacket 8 of the optical cable 7 to prevent the optical cable 7 from slipping out from the holding tube 5. A release tool 16 is attached to the other end of the base 1.
is provided by the connecting band 17. This release tool has a hole 18 through which the optical cable 7 is inserted, and a protrusion 19 on one surface thereof. By inserting this protrusion between the outer sheath 8 of the optical cable 7 and the holding cylinder 5, the engagement between the movable claw 15 and the outer sheath 8 is released.

伝送機を得ることができる利点がある。"Effects" As described above, this invention inserts the holding tube 5 into the through hole 2 of the base 1, and the fiber of the optical cable 7 inserted through the holding tube 5 is inserted into the accommodation chamber 3 connected to the through hole 2. The core wire 9 is connected to the light emitting element or the light receiving element 12
A holding piece 10 is provided to hold the fiber core 9 so as to optically oppose it, and a light emitting element or a light receiving element 12 is provided in the housing chamber 3 to optically face the end of the fiber core wire 9. 5 is provided with a claw 15 that engages with the sheath 8 of the optical fiber 7 and prevents it from moving, so that the optical cable 7 is securely held against the base 1 and the fiber core 9 and light emitting Since the optical coupling with the element or the light receiving element 12 is extremely stable, there is an advantage that a highly reliable optical transmitter can be obtained.
