Abstract

A sleeve is adapted for a casing of an optical fiber. The casing has a projection and spaced-apart first and second protrusions. The sleeve includes a limiting unit, a first abutment structure, a second abutment structure and a grip unit. The limiting unit includes two clamping walls for clamping the casing and for abutting against the second protrusion of the casing. The first abutment structure is on the limiting unit for abutting against the projection of the casing. The second abutment structure is on the limiting unit for abutting against the first protrusion 35 of the casing. The grip unit extends from the limiting unit and is movable for driving the limiting unit to move the casing.

Claims

1. A sleeve for an optical fiber connector, the optical fiber connector including an optical fiber cable, and a casing that has a main body connected to the optical fiber cable and a covering sleeved on the main body, the casing further having a projection that protrudes from the main body, and spaced-apart first and second protrusions that protrude from the covering in opposite directions, said sleeve comprising:

a limiting unit including

a limiting wall, and

two clamping walls that extend respectively from opposite ends of said limiting wall, that are adapted for clamping the covering of the casing of the optical fiber connector, that cooperate with said limiting wall to define a clamping space adapted for accommodating the covering of the casing, and that are adapted for abutting against the second protrusion of the casing;

a first abutment structure provided on said limiting unit, and adapted for abutting against the projection of the casing;

a second abutment structure provided on said limiting unit, and adapted for abutting against the first protrusion of the casing; and

a grip unit extending rearwardly from said limiting unit, forwardly movable for driving a forward movement of said limiting unit to thereby move the casing forwardly through abutment between said first abutment structure and the projection, and rearwardly movable for driving a rearward movement of said limiting unit to thereby move the casing rearwardly through abutment between said second abutment structure and the first protrusion and through abutment between said clamping walls and the second protrusion.

2. The sleeve as claimed in claim 1, wherein said limiting wall has:

a first segment connected to said grip unit and provided with said first abutment structure;

a second segment disposed at a front side of said first segment and provided with said second abutment structure; and

an engaging hole defined between said first and second segments, being in spatial communication with said clamping space, and adapted for insertion of the projection and the first protrusion.

3. The sleeve as claimed in claim 1, wherein:

said clamping walls are adapted for clamping removably the covering of the casing; and

each of said clamping walls has an arm portion extending downwardly from a respective one of said opposite ends of said limiting wall, and a hook portion extending transversely from said arm portion, and adapted for abutting against the second protrusion of the casing.

4. The sleeve as claimed in claim 3, wherein said grip unit includes a grip connected to a rear end of said first segment of said wall, and a plurality of anti-slip members formed on said grip.

5. The sleeve as claimed in claim 1, wherein:

said limiting wall has

a first segment connected to said grip unit,

a second segment disposed at a front side of said first segment and provided with said second abutment structure, and

a first engaging hole defined between said first and second segments, being in spatial communication with said clamping space, and adapted for insertion of the first protrusion; and

one of said clamping walls has

a first section provided with said first abutment structure,

a second section disposed at a front side of said first section, and

a second engaging hole defined between said first and second sections, being in spatial communication with said clamping space, and adapted for insertion of the projection.
