のみならず、光７丁イパコネクタの簡易締結方式として
広く使用されることが予想される。The fastening methods for optical fiber connectors can be roughly classified into rotary fastening methods such as screw fastening and non-rotary fastening methods. The non-rotating fastening method is superior to the rotating fastening method in terms of operability and vibration resistance, and in the future it is expected to be widely used not only for electrical connectors but also as a simple fastening method for optical 7-way IPA connectors. is expected.

アイバコード５の先端部を収容し、外径が矩形である。An example of an optical connector plug used in a conventional non-rotating fastening method is shown as the first factor. In the figure, the optical fiber cord 5
A cylindrical ferrule 3 is fixed to the tip. This 7
The outer side of the errule, the spring 4 and the spring stopper 11 are arranged. The stopper 11 is glued or screwed to the swivel of the seven errules. The spring 4 abuts the stopper 11 on one side and the inner wall of the housing 1 on the other end. The housing 1 accommodates the ferrule 3 and the tip of the optical fiber cord 5 therein, and has a rectangular outer diameter.
またハウジング１の外側の２つの側面には溝１ｃ、ｌｃ
’ 、ｌｄ、ｌｄ’が形成されている。Also, grooves 1c and lc are provided on the two outer side surfaces of the housing 1.

、 １ｂ’が突出し、その梁シの先端部には突起１ａ、
ｌａ’が形成されている。The housing 2 is in contact with the outside of the housing 1, and cantilevers 2a and 2a' are formed at the rear end. Furthermore, protrusions 2b and 2b' that engage the grooves 1d and ld' are formed at the tips thereof, thereby preventing movement f of the housing 2 in the optical axis direction. There is a cantilever beam tb on the left side of housing 1.
, 1b' protrudes, and the tip of the beam has a protrusion 1a,
la' is formed.

つけられる。When connecting the plug to the adapter, as shown in FIG. Then, fit the protrusions 1a and la' into the grooves 6a of the plug. Next, as shown in FIG. 3, the protrusion 2b of the housing 2 is
, 2b' are removed from the grooves 1d, ld', and the housing 2 is moved in the direction of the arrow A. Then, the protrusions 2b, 2b' are fitted into the grooves 1c, lc' on the outside of the housing 1, respectively. As a result, the connecting portion is pressed against the housing 2 from the outside.
しかし上記従来例では、プラグをアダプタに接続した状
態においてハウジング２のアダプタ側の先端部は片持梁
１ｃ、Ｊｃ’の外側を覆うのみで、アダプタ６には接触
しない。この結果、プラグは光軸に垂直な方向の曲げに
対して変形しやすい。However, in the conventional example, when the plug is connected to the adapter, the tip of the housing 2 on the adapter side only covers the outside of the cantilever beams 1c and Jc' and does not contact the adapter 6. As a result, the plug is easily deformed when bent in a direction perpendicular to the optical axis.
この変形を防止するため、ハウジング２のアダプタ側の
先端部が接続時にアダプタ６のフランジに当接するよう
ハウジング２の長さをアダプタ側の方向に長くすること
が考えられる。しかし、このように長くすると、接続時
にハウジング１の片持梁１ｂ、１ｂ′がハウジング２に
よって外側から押えつけられ片持梁が広げにくくなる。In order to prevent this deformation, it is conceivable to increase the length of the housing 2 in the direction toward the adapter so that the tip of the housing 2 on the adapter side comes into contact with the flange of the adapter 6 during connection. However, if the length is increased in this way, the cantilevers 1b, 1b' of the housing 1 are pressed down from the outside by the housing 2 during connection, making it difficult to expand the cantilevers.

にくくなるという欠点もある。It is also conceivable to increase the length of the contact portion between the housing 1 and the housing 2 in FIG. 1, but this would result in an increase in the size of the plug. Furthermore, since the cantilevers 2a and 2a' are greatly deformed in the direction of the arrow B shown in FIG.
There is a disadvantage that a is easily damaged. Furthermore, since the outside of the housing 2 is grabbed and pressed during the fastening operation, there is also a drawback that the housing 2 becomes difficult to slide on the outside of the fitting 1.
本発明の目的は、プラグとアダプタとの締結力が大きく
、着脱操作が容易で、しかもプラグの曲は等の外力に対
し、耐久性の大きい光フアイバコネクタを提供すること
にある。An object of the present invention is to provide an optical fiber connector that has a large fastening force between a plug and an adapter, is easy to connect and disconnect, and is highly durable against external forces such as bending of the plug.

The deformation of a' is limited and the cantilever is less likely to break. In addition, in FIG. 4<13), when sliding the outside of the housing 7 toward the tip of the plug while grasping the outside of the housing 8, the pressure in the central axis direction of the housing 8 is
, 8a' and protrusion B b + s b'. Therefore, the housing 8 does not slide easily, and connection workability is improved. Furthermore, during connection, the tip of the housing 8 is fitted into the adapter 6, so that the connecting part between the plug and the adapter is firmly held by the housing 8, and the housing 8 does not move against external force in the direction of the central axis of the plug. There isn't. Therefore, the external force applied to the ferrule #1 due to bending is minimal, and the ferrule is unlikely to be damaged.
