    • A receptacle has an end surface supported along a plane extending at right angles to the axis of the receptacle and a contact surface at the other end. The contact surface also extends at right angles to the axis of the receptacle. A receptacle holder has a recess within which the receptacle is received. An adjusting mechanism is devised to adjust radial position of the receptacle. A lens holder is attached to the other end of the receptacle holder. A slide member has a sliding surface in surface contact with the contact surface of the receptacle. The slide plate is urged toward the one end of the receptacle so as to bring the sliding surface into contact with the contact surface of the receptacle. An optical fiber is inserted into the receptacle through a ferrule. If the optical fiber is twisted, the slide plate permits ready rotation of the receptacle in a torsional direction so as to prevent the optical fiber from being subjected to torsional stress. Also, opposite ends of the receptacle are gripped in surface contact and supported in a plane extending at right angles to the axis of the receptacle holder. This arrangement prevents inclination of the receptacle and thus, optical misalignment of the optical fiber and the lens if the weight of the optical fiber is applied.
    • 容器具有沿着与插座的轴线成直角延伸的平面支撑的端面和另一端的接触表面。 接触表面也与插座轴线成直角。 容器保持器具有容纳容器的凹部。 设计调节机构来调节容器的径向位置。 透镜保持器附接到容器保持器的另一端。 滑动构件具有与容器的接触表面表面接触的滑动表面。 滑板朝向容器的一端被推压,以使滑动表面与容器的接触表面接触。 光纤通过套圈插入插座。 如果光纤被扭曲,则滑板允许容器在扭转方向上准备旋转,以防止光纤受到扭转应力。 此外,容器的相对端被表面接触地夹持并且被支撑在与插座保持器的轴线成直角延伸的平面中。 这种布置防止了插座的倾斜,并且因此如果施加光纤的重量,则光纤和透镜的光学未对准。
