Abstract:
A fiber fixing device for a linear lightguide, comprising:a cylindrical chuck including a hollow space along an axis of said chuck for receiving an optical fiber, a grasp part for grasping said optical fiber received in said hollow space, and a coupling part coupling said grasp part, wherein said grasp part has a first outer diameter larger than a second outer diameter of another portion of said chuck, and said chuck further includes a sloping shoulder transitioning between said first outer diameter of said grasp part and said second outer diameter of said another portion;an elastic tubular body that is fitted around said grasp part of said chuck after having been elastically expanded outwardly, such that said elastic tubular body exerts a radially inwardly directed elastic restoring force onto said chuck whereby said grasp part grasps said optical fiber; anda fiber guide, having a cavity receiving said chuck and said elastic tubular body therein and a hole for receiving a forward end portion of said optical fiber therein, and including a stopper part in said cavity arranged to be struck by and in contact with a forward end portion of said chuck, and being adapted for fitting said elastic tubular body onto said grasp part of said chuck by bringing said forward end portion of said chuck into contact with said stopper part and pushing said elastic tubular body toward said stopper part from said another portion of said chuck, over said sloping shoulder and onto said grasp part of said chuck.
