Abstract

A holder for an optical fiber ferrule end face grinding apparatus is provided which can grind an increased number of optical fiber ferrules simultaneously. The bolder comprises a holder plate provided with a plurality of ferrule insertion holes, a seat extending to at least one insertion hole and having a first wall, and a second wall on a side of the insertion hole opposing the seat. A slidable holding member including a front face facing the second wall, and an inclined rear face is disposed on the seat. A depression member is mounted on the holder plate that presses downwardly on a rod member disposed on the inclined rear face. As the depression member is operated, the rod member is pressed downwardly along the first wall, and the holding member is pushed forward such that a ferrule is clamped between the front face and the second wall.

Claims20

Dependent claims

A holder for an optical fiber ferrule end face grinding apparatus that holds a plurality of optical fiber ferrules, the holder comprising:

a holder plate provided with a plurality of insertion holes into each of which one of said ferrules is inserted, a seat provided for said insertion holes that extends to one side of at least one of said insertion holes, said seat having a first wall located at a distance from the insertion hole, and a second wall provided on a side of the insertion hole opposite said seat;
a holding member disposed on said seat, said holding member being slidable in a direction to adjust the spacing between the holding member and said second wall, the holding member including a front face confronting said second wall, and a rear face inclined relative to the first wall;
a rod member disposed on said inclined rear face of said holding member;
and
a depression member provided on the holder plate at an outside of said first wall of said seat that exerts a force on said rod member,
wherein by the operating of said depression member, said rod member is pressed downwardly along said first wall of said seat, by which action said holding member is pushed out forwardly such that said ferrule is held by said front face of the holding member and said second wall.

3 more elements

A holder for an optical fiber ferrule end face grinding apparatus for holding a plurality of optical fiber ferrules, the holder comprising:

a holder plate having a plurality of insertion holes arranged about the center of said holder plate, each insertion hole adapted to receive one of said ferrules, a seat provided in said holder plate for at least one of said insertion holes, said seat extending radially outside of said one insertion hole, said seat having a first wall spaced radially outwardly from said one insertion hole, a second wall provided on a side of the insertion hole radially inwardly of said first wall;
a holding member adapted to be mounted on said seat, said holding member having a front face confronting said second wall and a rear face inclined relative to the first wall, said holding member being slidable in said seat in a radial direction to adjust the spacing between the front face of the holding member and said second wall;
a rod member adapted to bear against said inclined rear face of said holding member;
and
a depression member adapted to be attached to the holder plate radially outwardly of said first wall, said depression member adapted to exert a force on said rod member so as to urge the holding member toward said second wall.
