ウジングｆｌ） Ｖｃ螺合することにより固着する。Embodiment In FIG. 3, (1) is an adapter housing, and the inner surface of this adapter housing (1) is provided with zero protrusions and a reverse thread is cut. (3) is a sleeve, which is provided with a large part (not shown) in the vertical direction to have elasticity, and is provided with a concave Ffr) on the outer surface, and a screw 05 is provided between this concave part 04) and one end surface. ). The diameter of the reverse thread on the adapter housing (7fl) is the same as the diameter of the thread on the sleeve (3).
Make it smaller than the diameter of +5). When installing the sleeve (3) into the adapter housing (1), use the elasticity of the sleeve (t3) by pressing the sleeve (3) from the outside as shown in Figure 4 (b)). With the diameter narrowed, insert the screw (151
Once the diameter of the sleeve (3) has passed, the elasticity of the sleeve (3) causes the sleeve (3) to return to its original diameter. Here, sleeve (3)
The diameter of the sleeve (3) II'! is larger than the diameter of the reverse thread Q field of the adapter housing fl). Fixed. However, rotation is free. When connecting the connector bracket (7), insert the optical fiber (
When the ferrule (6) with a built-in ferrule (6) is inserted, the enlargement of the diameter of the sleeve (3) is inserted between the concavity of the sleeve (3) and the protrusion (l) of the adapter housing +1. Since there is a gap, the diameter of the sleeve (3) becomes larger when the ferrule (6) is inserted, and it functions as an alignment mechanism for coupling the ferrule (6).
It is fixed by screwing the mounting nut (181 to the housing fl) Vc through the washer Oη.
