Since it is constructed by bending and forming a sheet of metal plate material, when the caulked part 23 is compressed, the cylindrical part 21 is affected by distortion and deflection, which adversely affects the cladding part. affect In addition, the molding technology is structurally difficult, and there are difficulties in manufacturing. In the latter case, the covering part 11 of the cylindrical member made of a single metal plate is connected to the optical fiber by compressing the covering at the tip of the optical fiber. The cladding at the tip of the optical fiber is susceptible to deformation and distortion. In addition, in order to connect the optical fiber to the metal cylindrical member in the first step, the housing 2 is connected in the next step.
This method is very troublesome because it requires two steps: inserting a cylindrical member connected to an optical fiber into the fiber optic.

るように切断加工される。 That is, a large number of metal holding bands 6 curved in a substantially U-shape are arranged at appropriate intervals, and these are connected to a long material via a cutting connection piece 7. The length material 5 is moved intermittently by an intermittent feeding mechanism, and the compression part 2 of the plug body A configured as described above is inserted from the opening 6a of the metal holding band 6 at the first position, and then At the second position, the holding band 6 is slightly held around the compression part 2 so that the compression part 2 is not compressed, and at the next third position, the plug body A is held together with the holding band 6 into a long length. This is done sequentially by cutting it off from the material 5. When connecting the plug formed in this way to the end of the optical fiber K, the optical fiber K from which the outer sheathing part 8 of the end has been peeled off is inserted into the through hole 3 of the plug body A, and the optical fiber K is passed through the cladding 9. The compressed portion 2 is placed in the narrow diameter portion 3a of the hole 3 (see FIGS. 6 and 7), and compressed and tightened by squeezing the holding member 6 from the outer periphery using an appropriate crimping tool (not shown). The compression pieces 2a, 2a are pressed around the optical fiber K (see FIGS. 8 and 9), thereby firmly connecting the optical fiber K and the plug.
The tip of the optical fiber clad 9 protruding from the tip of the plug is cut so as to be flush with the tip of the plug in post-processing.

る。 The cladding part 9 of the shiny fiber, which is very susceptible to damage due to peeling of the covering part at the tip, is attached to the narrow diameter part 3 of the through hole 3 of the plug body 1 made of synthetic resin.
This is because the plug A and the shiny fiber are connected by compressing the metal holding band 6 from the outside while they are held together at point a.
The cladding 9, which is easily damaged when the enclosing band is compressed, is stably held by the narrow diameter portion 3a of the internal synthetic resin plug body 1, thereby preventing the occurrence of distortion, bending, or damage.

フアイバーの接続が達成される。 In particular, the part compressed by the enclosing band 6, that is, the part where the radial slit 4 is formed, ends at the middle part of the large diameter part 3b of the through hole 3, and there is an appropriate distance between it and the cladding part. Since the cladding is left in place, the subtle effects of distortion and bending of each part during compression on the cladding part are alleviated, thereby achieving even more precise optical fiber connection.

Connected to the long material via 7,
This elongated material 5 is intermittently moved by an intermittent feeding mechanism, and the compressed part 2 of the plug body A is inserted from the opening 6a of the metal holding band 6 at the first position, and then the compressed part 2 of the plug body A is inserted into the second position. At the position, the holding band 6 is slightly held around the compressed part 2 so that the compressed part 2 is not compressed, and at the next third position, the plug body A is pulled together with the holding band 6 from the long material 5. By separating and manufacturing, it can be manufactured continuously in assembly line operations, which has various remarkable effects such as being able to provide products at low cost.

The through hole 3 is formed to have approximately the same diameter as the diameter of the cladding 9 from which the outer sheathing part 8 of the optical fiber K is removed at the tip part 3a on the insertion part side, and the other part 3b is formed to have a diameter smaller than the diameter of the outer sheathing part. The compressed portion 2 is formed to have a slightly larger diameter, and the compressed portion 2 extends from the end to the larger diameter portion 3 of the through hole 3.
A plug body A is prepared, which is divided into a plurality of compressed pieces 2a by a radial slit 4 extending in the axial direction to near the middle of b, and on the other hand, a large number of approximately U-shaped curved metal holding bands are prepared. 6 are arranged at appropriate intervals in the length direction with respect to the long material 5, and these are connected to the long material via the cutting connection piece 7, and the long material 5 is fed by an intermittent feeding mechanism. inserting the compressed part 2 of the plug body A through the opening 6a of the metal holding band 6 at the first position while intermittently shifting the plug body by
In the next second position, the hugging band 6 is slightly wrapped around the compression part 2 so that the compression part 2 is not compressed, and in the next third position, the plug body A is lengthened together with the hugging band 6. A method for manufacturing an optical fiber plug separated from a length material 5. 2. A through hole 3 for inserting an optical fiber is provided in the shaft core of a synthetic resin plug body A having an insertion portion 1 at one end and a compression portion 2 at the other end. is formed to have approximately the same diameter as the diameter of the clad 9 from which the outer sheathing portion 8 of the optical fiber K is removed at the tip portion 3a on the insertion portion side, and the other portion 3b is formed to have a slightly larger diameter than the diameter of the outer sheathing portion. Furthermore, the compressed portion 2 extends from the end to the large diameter portion 3 of the through hole 3.
It is divided into a plurality of compressed pieces 2a by a radial slit 4 extending in the axial direction to near the middle of b, and furthermore, a holding band 6 made of a metal plate is slightly bent around the compressed part 2. Lever holding band 6
An optical fiber plug configured such that compression pieces 2a are compressed to the center of the shaft by compressing the fibers from the outside.
