形成されている。(Prior art) In order to downsize and simplify the structure, conventional optical connectors have a straight optical connector ferrule with an outer diameter of 2.499mm-φ, and the plug structure consists of the optical connector ferrule, pressure spring, and cap each separately. It is formed by a combination of three parts.

。After inserting the optical connector ferrule (13) into the split sleeve (12) from both sides of the adapter (11) and positioning it, the rear end of the optical connector ferrule (13) is inserted into the pressurizing spring (!4). Press in the axial direction with the cap (
15) to the end (■') of the adapter (!1) with a screw (
16) By doing so, coupling of optical connectors is realized.
（解決しようとする問題点）
上述した従来の光コネクタによれば、次に列記するよう
な問題点が存在する。(Problems to be Solved) According to the conventional optical connector described above, there are the following problems.
■光コネクタフェルールがストレート形状であるためフ

計値と異なり最悪の場合には加圧バネが全圧縮されてバ
ネの機能を果さなくなることがある。■Since the optical connector ferrule has a straight shape, the rear end of the ferrule is pressed by a pressure spring, but when attaching the optical fiber RIS wire to the rear end of the ferrule, adhesive sometimes adheres or bulges unevenly. As a result, the ferrule becomes longer, so we try to remove the adhered adhesive later, but it is not possible to remove it sufficiently, and in the worst case, the pressure spring is different from the designed value. may become fully compressed and no longer function as a spring.

ファイバ心線を把持した場合は心線に損傷を与える等信
頼性が悪くなり、又保護部材を挿着するには作業性が悪
く、構造が複雑となる。It is necessary to grasp the optical fiber core with the ferrule attached or the protective member inserted on top of it to remove the ferrule. If the optical fiber core is grasped, it may damage the core wire, resulting in poor reliability. Moreover, the workability for inserting and attaching the protective member is poor, and the structure becomes complicated.
■光コネクタフェルールがストレート形状であるため、
フェルールの回り止め機構がなく、又アダプタとキャッ
プの連Ｖがネジ締結であるためフェルールが回転してし
まう。■Since the optical connector ferrule is straight,
There is no mechanism to prevent the ferrule from rotating, and the connection V between the adapter and the cap is screwed together, so the ferrule rotates.
■加圧バネとキャップが別個の２部品であるため、キャ

性、作業性が悪い。■Since the pressure spring and the cap are two separate parts, when you grip the cap and pressurize the pressure spring, the spring will buckle and the inner optical fiber core will also be affected by the aperture. The reliability is poor as it may cause damage (and the ease of handling and work is poor because it is made of two parts).

1) and the optical connector ferrule (3) can be attached and detached by grasping the phenol flange (32), so the reliability is significantly improved without damaging the optical fiber (A), and the pressure is reduced. Member (4) is the flange part (32)
This eliminates the influence on the pressure spring design due to adhesive adhesion and swelling at the rear end of the ferrule. The shape of the flange portion (32) of this ferrule is octagonal for the purpose of miniaturization, directionality during coupling, and ease of grip during attachment and detachment.

（同図二）。As shown in Figure 2, the coupling method is as follows: First, grasp the octagonal flange part (32) of the optical connector ferrule (3) and insert the coupling part (31) of the ferrule into the adapter (1).
After (a) in the figure, the gripping part (44) of the pressure member (4) is held to suppress the optical connector ferrule (3) (opening in the figure), and the pressure spring (47) is compressed. It was then stored in a storage case (Figure C) and the optical connector was held under pressure (Figure 2).
