发明名称 Adaptive device for inspecting endfaces of fiber-optic connector having multiple rows of fibers
摘要 A device for shifting the imaging axis of a microscope for inspecting endfaces of a fiber-optic connector having multiple rows of endfaces has a supporting body for receiving a microscope; a first swinging lever mounted on top of the supporting body and rotatable about a first swinging axis perpendicular to the imaging axis of the microscope; a first connecting piece extending from the first swinging lever towards the imaging axis; a second swinging lever pivoted on the first connecting piece and rotatable about a second swinging axis perpendicular to the first swinging axis; and a fitting tip connected to the second swinging lever for interfacing with the fiber-optic connector. Using two sets of biasing means and adjustment drivers, the imaging axis passing through the supporting body and the fitting tip can be shifted in two mutually perpendicular directions to selectively align with any endface of the fiber-optic connector.

主权项 1. A device for shifting the imaging axis of a microscope in two mutually perpendicular directions for inspecting individual endfaces of a fiber-optic connector having multiple rows of endfaces, the device comprising: a supporting body having a first portion and a second portion, wherein the first portion has a rear end adapted for receiving an optical tube of the microscope and a passageway extending from the rear end to a front end of the first portion, such that the imaging axis of the microscope is allowed to pass through the passageway, and the second portion is disposed above the first portion and extends rearwards over the optical tube of the microscope; a first swinging structure comprising a first swinging lever and a first connecting piece, wherein the first swinging lever has a rear end and a front end, wherein the rear end is rotatably mounted to the second portion of the supporting body, such that the first swinging lever is rotatable relative to the supporting body about a first swinging axis that is substantially perpendicular to the imaging axis of the microscope;the first connecting piece is connected to the front end of the first swinging lever and extends, in front of the supporting body, towards the imaging axis of the microscope, anda recess is formed on a front side of the first connecting piece; a second swinging structure comprising a second swinging lever and optionally a second connecting piece, wherein the second swinging lever is pivotally mounted to the first connecting piece and received in the recess of the first connecting piece, such that the second swinging lever is rotatable about a second swinging axis that is substantially parallel to a normal plane of the first swinging axis, wherein a passageway aligned with the passageway of the supporting body is cut through a lower end of the second swinging lever; and the optional second connecting piece is connected to an upper end of the second swinging lever and extending rearwards over the first swinging lever; a fitting tip attached to a front side of the passageway of the second swinging lever and adapted for interfacing with a multi-fiber connector, the fitting tip having an interior channel aligned with the passageway of the second swinging lever, such that the imaging axis of the microscope is allowed to pass therethrough to intersect with fiber-optic endfaces of the multi-fiber connector; a first biasing means disposed between the second portion of the supporting body and the first swinging lever for rotationally biasing the first swinging lever about the first swinging axis; a first adjustment driver disposed to interface with the supporting body and the first swinging lever and adapted to swing the supporting body relative to the first swinging lever against the first biasing means, thus moving the imaging axis of the microscope relative to the fitting tip along a first straight trajectory over the fiber-optic endfaces of the multi-fiber connector interfaced with the fitting tip; a second biasing means disposed between the second swinging structure and the first swinging structure or the supporting body for rotationally biasing the second swinging lever about the second swinging axis; and a second adjustment driver disposed to interface with the first swinging structure and the second swinging structure and adapted to swing the second swinging lever relative to the first swinging structure against the second biasing means, thus moving the imaging axis of the microscope relative to the fitting tip along a second straight trajectory over the fiber-optic endfaces of the multi-fiber connector interfaced with the fitting tip, wherein the second straight trajectory is substantially perpendicular to the first straight trajectory.
