【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、光伝送用に使用する発光または受光素子を含
む光データリンク用コネクタに関し、特に基板実装後に
回転可能としたコネクタに関する。Description: TECHNICAL FIELD The present invention relates to an optical data link connector including a light emitting or light receiving element used for optical transmission, and more particularly to a connector that is rotatable after mounting on a board.
従来、光伝送用に用いる発光または受光素子を含む光デ
ータリンク用コネクタは、基板実装後コネクタ全体が基
板に固定されているため、その取付方向を変えることは
できないものとなっていた。Conventionally, in an optical data link connector including a light emitting or light receiving element used for optical transmission, the entire connector is fixed to the substrate after mounting on the substrate, so that the mounting direction cannot be changed.
第４図は従来の光データリンク用コネクタの使用時の上
面図である。すなわち、光ファイバ３と接続された光デ
ータリンク用コネクタ１’は、基板４に取付けられた光
コネクタ（図示せず）と接続される。この場合コネクタ
１’の取付方向は定まっていた。FIG. 4 is a top view of a conventional optical data link connector when in use. That is, the optical data link connector 1 ′ connected to the optical fiber 3 is connected to the optical connector (not shown) attached to the substrate 4. In this case, the mounting direction of the connector 1'has been fixed.

部分）と発光または受光素子との不整合を生じ、光結合
損失が大きくなるという欠点があり、さらにその応力が
大きい場合にはコネクタ結合部分を破壊させるという欠
点もある。In this way, in the conventional structure, the optical data link connector is fixed to the board. Therefore, when the connector is installed once the direction is determined, the board including the opposing connector or the device system is moved, the connector of this connector is moved. Since the direction does not change, the optical fiber is unduly stressed and twisted, which shortens the life of the optical fiber.
Further, since unreasonable stress is applied to the coupling portion between the optical fiber and the optical data link connector, a mismatch between the tip (light emitting portion) of the optical fiber and the light emitting or light receiving element occurs, resulting in a large optical coupling loss. However, if the stress is large, there is a drawback that the connector coupling portion is destroyed.

An object of the present invention is to provide an optical data link connector that does not cause mismatch and can reduce optical coupling loss.
