Title:
OPTICAL FIBER FERRULE POLISHING HOLDER
Document Type and Number:
Japanese Patent JP2020163475
Kind Code:
A
Abstract:
To provide an optical fiber ferrule polishing holder capable of restraining deflection of an optical fiber ferrule even when the optical fiber ferrule is pressed with a given pressure regardless of an individual difference in a recess of the optical fiber ferrule.SOLUTION: An optical fiber ferrule polishing holder 20 used for polishing a optical fiber ferrule 30 with a rectangular cross section has an insertion hole 21 into and from which the optical fiber ferrule 30 is inserted and extracted, and a supporting wall 21A1 of the insertion hole 21 has a body part 21 capable of abutting to the optical fiber ferrule 30 and a fixing part 25 (29) having a pressure wall 25B (29B) for pressing the optical fiber ferrule 30 toward the support wall 21A1. The supporting wall 21A1 is inclined at a prescribed angle to a vertical axis vertically extended from a polishing surface 13 of an optical fiber ferrule polishing device 10. The supporting wall 21A1 has a projection part 21C toward the pressing walls 25B, 29B.SELECTED DRAWING: Figure 6
