FIG. 6 is an example of a multi-core optical fiber connector.

There is one shown in Figure 7. Figure 6 shows A of multi-core optical fiber 9.
-A sectional view.

Figure 6 shows a pair of optical fiber Zorags 9, 9' fitted with optical fiber tapes 6, 6', and Figures 7 (a), (b) (
C) shows one optical fiber plug 9 and optical fiber plug 6 disassembled.

As shown in Figure 6, this multi-core optical fiber connector is
A pair of optical fiber Zorags 9, 9' are connected to two guide pins 3.
1.31, optical fiber graders 9, 9'
A plurality of bare optical fibers 5.5'(5' is not shown) protrude from the end of the optical fiber 6' inserted into the coupling surface 30-1 from the other surface 30-2. The ends of the guide pins 31 and 31 of the coupling surface 30-1 are arranged in a straight line inside the guide pins 31 and 31 and are optically coupled.

As shown in FIG. 7, the optical fiber plug 9 connects the bare optical fiber 5

The optical fiber insertion grooves 10 and the optical fiber insertion holes 11 are arranged on the same straight line at the same arrangement pitch. Further, the centers of the guide pin insertion hole 12.degree. 12 and the optical fiber insertion hole 1 are arranged in parallel. Therefore, when the optical fiber plugs 9 and 9' are butted and coupled, the conventional assembly method of inserting the bare optical fiber 5 into the guide pin 31° pub plug 9 is to attach the optical fiber tape 6 as shown in FIG. The tip of the bare optical fiber 5 from which the coating has been removed is inserted into the optical fiber tape insertion hole 16.
Then, the bare optical fibers 5 are inserted into the optical fiber insertion grooves 10 and arranged, and the bare optical fibers 5 are guided through the optical fiber insertion grooves 10 and moved forward, and the bare optical fibers 5 are gradually inserted into the optical fiber insertion holes 11. is inserted through and protrudes from the end face 38 of the optical fiber plug. After confirming that the bare optical fiber 5 has been protruded, adhesive (not shown) is dripped into the concave portion 39 of the optical fiber plug 9, and after the adhesive has hardened, the bare optical fiber 5 is protruded from the end face 38 of the optical fiber plug 9.

It was something to do.

[Problem to be solved by the invention]

In the conventional assembly of such a multi-core optical fiber plug, there is a distance of several millimeters between the bare optical fiber and the optical fiber insertion groove arranged at the rear of the optical fiber plug, and there is a distance between the bare optical fiber and the optical fiber insertion groove. There is nothing in the space between the fiber insertion groove to guide the movement of the bare optical fiber, so when gradually inserting the bare optical fiber into the optical fiber plug and into the optical fiber insertion groove, multiple bare optical fibers It was difficult to simultaneously align and insert the optical fibers into the optical fiber insertion groove all at once, and required considerable skill.

In addition, since the optical fiber insertion groove has a semicircular or V-shaped cross section and is open at the top, while the bare optical fiber is moving forward in the optical fiber insertion groove, the bare optical fiber is inserted into the optical fiber insertion groove. There is also a drawback that the optical fiber cannot be easily inserted into the optical fiber insertion hole of the optical fiber plug, which is the ultimate purpose. Furthermore, if the position of the optical fiber is forcibly adjusted using a cotton swab or the like and the optical fiber is inserted by force, the optical fiber may break.

The present invention has been made in view of the above circumstances, and its purpose is to eliminate the need for skilled techniques for inserting a bare optical fiber into the optical fiber insertion hole of an optical fiber plug, and to easily insert the bare optical fiber. An object of the present invention is to provide a method for assembling a multi-core optical fiber plug and an assembling device for the same.

The third step is to move the optical fiber, and then insert the coated optical fiber part of the optical fiber into the rear part of the multi-core optical fiber plug.

Since the method for assembling multi-core optical fibers has not yet been carried out, the assembling apparatus is used to assemble a multi-core optical fiber plug unit, in which a multi-core optical fiber plug and an optical fiber guide member are fastened together by left and right side pin fixing members, on board A. A movable stage equipped with a sliding means for sliding in the longitudinal horizontal direction is provided on the board B provided above the board A, and the end is pivotally supported on a shaft suspended horizontally on the movable stage, and a predetermined position on the horizontal surface is provided.
