Abstract
To securely hold a ferrule at a prescribed position with a prescribed posture by providing a support portion to position and hold a posture of the ferrule and a displacement portion to hold the ferrule inserted into a ferrule insertion hole of the support portion so as not to slip off the insertion hole. A ferrule 420 is inserted into a ferrule insertion hole 361 of a support portion 360 from a tip end portion side of the ferrule 420 and set at a position in which a holding tool 422 is engaged with a rotation regulating hole 333. When a lever member 344 is operated to a clamping position, an adjusting screw 343 is rotated right-handedly, and a displacement portion 370 screwing into a screw portion 343a of the screw 343 is displaced with a thin portion 373 as a supporting point in a direction to approach the support portion 360. Owing to this displacement, a pressuring portion 371 of the displacement portion 370 presses the tip end portion of the ferrule 420 in a direction roughly perpendicular to an axial line L to hold the ferrule 420 so as not to slip off the insertion hole.
Description
Technical field
The present invention relates to a kind of when utilizing micro-interference instrument apparatus (being also referred to as the interference microscope device) that the shape of the top ends of the sleeve pipe that forms optical connector etc. is resolved, for fastener that sleeve pipe is remained in the employed sleeve pipe of certain position before the object lens and the micro-interference instrument apparatus that is equipped with this fastener.
Background technology
In recent years, the research and development to employed optical fiber in the optical communication have obtained development energetically.As everyone knows, this optical fiber comprises the fibre core about external diameter 10 μ m for example, be located at the clad about for example external diameter 125 μ m of its periphery, and for optical fiber is connected to each other, disposes sleeve pipe at its connecting terminal.
So-called sleeve pipe is meant the cylindrical structural member of the formation optical connector of the terminal that is maintained fixed optical fiber in order to connect optical fiber.After sleeve pipe adopts the central part at its external diameter to insert optical fiber and fix with bonding agent etc., be mirror-like and make the top end face of 2 sleeve pipes involutory, maintained 2 optical fiber respectively can be connected and constitute by its top is ground.
The top end face of this sleeve pipe is known have grind for the plane that optical axis become orthogonal with grind to the plane that optical axis become oblique, but the execution that recently a kind of PC (phisicalcontact) that makes top end face form spherical shape grinds is noticeable, its utilization makes the top end face of sleeve pipe make top end face produce elastic deformation to fashionable pressing force, and cocoa improves cannula tip face tack each other.
Yet, in order to reduce the optical loss of following optical fiber to connect, by JIS sleeve pipe is defined high-precision plurality of specifications, to imposing the sleeve pipe of above-mentioned PC polishing, just define the position deviation etc. of the core centre (the profile center of optical fiber) of the summit of spherical top end face of scale error, sleeve pipe of the radius-of-curvature of top end face and optical fiber, reach the specification of 6 μ m level.
For whether the sleeve pipe of checking made meets the specification, use the micro-interference instrument apparatus.This micro-interference instrument apparatus adopts by interfering the interference fringe of gained to be observed to the object light of carrying the surface configuration of having held small detected body and refractive index equiphase information with reference to light, and the shape and the variation of this interference fringe carried out determination and analysis, thereby obtain the phase information of detected body and constitute.
When utilizing this micro-interference instrument apparatus, when the sleeve pipe of made is checked, the certain position in object lens the place ahead of micro-interference instrument apparatus, the fastener that the sleeve pipe that need be used for checking keeps with the high position precision.In existing known techniques, use following patent documentation 1 described device to be used as this fastener.
Patent documentation 1 described fastener, employing is equipped with part (support sector) that sleeve pipe is supported to fix from the one side, to the part (moving part) of this removable formation of support sector, and between these support sectors and moving part, sandwich sleeve pipe and keep and constitute.Program as keeping sleeve pipe at first under the state that moving part fully leaves from support sector, temporarily is provided with sleeve pipe to support sector, then, moving part is moved to support sector, utilizes support sector and moving part to sandwich sleeve pipe and keeps.
