Abstract
In an inclination adjusting apparatus comprising two base members opposing each other, an adjusting screw for relatively inclining the two base members with respect to each other is rotatably threaded into and held by one of the two base members while projecting a leading end part from the one base member toward the other base member. The other base member is provided with a sphere-bearing surface opposing the leading end part of the adjustment screw. A rigid spherical member is held between the adjustment screw and the sphere-bearing surface.
Claims15
An inclination adjusting apparatus comprising two base members opposing each other, a support part for supporting said two base members such that said two base members are relatively inclinable with respect to each other, and an adjusting part for relatively inclining said two base members with respect to each other while using said support part as a fulcrum;
- said adjusting part comprising:
- an adjustment screw rotatably threaded into and held by one of said two base members while projecting a leading end face from said one base member toward the other base member;
- a sphere-bearing surface provided in the other base member so as to oppose a leading end face of said adjustment screw;
- a rigid spherical member disposed between said leading end face of said adjustment screw and said sphere-bearing surface;
- and
- a holding member for holding said spherical member at a position in contact with said leading end face and said sphere-bearing surface;
- said adjustment screw being rotated in a state where said spherical member is in contact with said leading end face and said sphere-bearing surface, so as to change the length of projection of said adjustment screw from said one base member, thereby adjusting the relative inclination between said two base members.
A ferrule clamping apparatus for holding a ferrule accommodated within a tubular member constituting an optical connector plug, said ferrule clamping apparatus comprising:
- a support having a first support piece for supporting said ferrule from one side;
- a shifter having a second support piece, disposed so as to oppose said first support piece across said ferrule supported by said first support piece while being displaceable between a clamp position in contact with the other side of said ferrule and a clamp release position separated from the other side;
- and
- a pressing member for pressing said shifter so as to displace said second support piece;
- wherein said first and second support pieces are formed so as to extend from the outside to inside of a leading end of said tubular member along an axis of said ferrule;
- wherein said shifter comprises a pressure receiving piece extending so as to oppose said second support piece across one side wall part of said tubular member;
- and
- wherein said pressing member is formed such that, when said pressure receiving piece is pressed toward said ferrule while in a state where a pressing point of said pressing member is in contact with said pressure receiving piece, said second support piece is displaced from said clamp release position to said clamp position so as to hold said ferrule with said first and second support pieces, and said first and second support pieces stop holding said ferrule when said pressing is released.
