Abstract

An optical fiber connector includes a fastener member threadedly connected to a main housing. A resilient member is received in the main housing and the fastener member, and abuts against the fastener member. A rotatable tube seat is sleeved by the resilient member, and is positioned by the main housing and the resilient member. A turning member is sleeved on the rotatable tube seat, and is sleeved by the fastener member. The rotatable tube seat is co-rotatable with the turning member. When the fastener member is loosened from the main housing, the turning member is rotatable relative to the fastener member to drive rotation of the rotatable tube seat relative to the main housing.

First claim

What is claimed is:

1 . An optical fiber connector comprising:
a main housing; a fastener member that is threadedly connected to a rear end portion of said main housing; a resilient member that is received in said main housing and said fastener member, and that has a rear end abutting against said fastener member; a rotatable tube seat that is sleeved by said resilient member and that abuts against a front end of said resilient member, said rotatable tube seat being positioned by said main housing and said resilient member in a front-rear direction; and a turning member that is sleeved on said rotatable tube seat, and that is sleeved by said fastener member, said rotatable tube seat being co-rotatable with said turning member; wherein when said fastener member is loosened from said main housing, said turning member is rotatable relative to said fastener member to drive rotation of said rotatable tube seat relative to said main housing.

2 . The optical fiber connector as claimed in claim 1 , wherein said rotatable tube seat has a coupling portion that is non-circular and that is sleeved by said turning member.

3 . The optical fiber connector as claimed in claim 1 , wherein said main housing has:
an outer surrounding wall that surrounds said rotatable tube seat and said resilient member, and that is threadedly connected to said fastener member; and an abutment wall portion that protrudes inwardly from an inner surrounding surface of said outer surrounding wall, and that abuts against a front end of said rotatable tube seat.

4 . The optical fiber connector as claimed in claim 3 , wherein
said rotatable tube seat has
a limiting end portion that is clamped between said abutment wall portion of said main housing and said front end of said resilient member,
a tube portion that extends rearwardly from said limiting end portion and that is sleeved by said resilient member, and
a coupling portion that is non-circular and that extends rearwardly from said tube portion, an outer diameter of said tube portion being greater than an outer diameter of said coupling portion; and
said turning member has
a positioning portion that is sleeved on said coupling portion, and
an operative portion that extends rearwardly from said positioning portion, an inner diameter of said positioning portion being smaller than said outer diameter of said tube portion.

5 . The optical fiber connector as claimed in claim 4 , wherein
said fastener member has
a threaded portion that is threadedly connected to a rear end portion of said outer surrounding wall,
an adjusting portion that extends rearwardly from said threaded portion and outwardly of said main housing, and that is annular,
a first retaining portion that protrudes inwardly from an inner surrounding surface of said adjusting portion, and
a second retaining portion that protrudes inwardly from said inner surrounding surface of said adjusting portion and that is disposed rearwardly of said first retaining portion, an inner diameter of said first retaining portion being greater than an inner diameter of said second retaining portion;
said resilient member is positioned between said limiting end portion of said rotatable tube seat and said first retaining portion of said fastener member; said positioning portion of said turning member is positioned between said resilient member and said second retaining portion of said fastener member; and said operative portion of said turning member extends rearwardly through said second retaining portion of said fastener member.

6 . The optical fiber connector as claimed in claim 3 , wherein
said main housing further has a protrusion portion that protrudes from an outer surface of said outer surrounding wall; and said optical fiber connector further comprises a press member that is pivotally connected to said protrusion portion and that is resiliently pressable to move toward said outer surface of said outer surrounding wall.

7 . The optical fiber connector as claimed in claim 6 , wherein
said protrusion portion has a recess that is formed at a rear end thereof; said press member has
a press body that has an end portion disposed in said recess and a free end portion inclined rearwardly from said end portion,
a pivot pin that extends through said end portion of said press body and said protrusion portion via said recess,
two engaging members that protrude respectively from two opposite lateral sides of said press body in opposite directions, and
a torsion spring that is sleeved on said pivot pin, that is disposed in said recess, and that has two ends respectively abutting against said outer surrounding wall and said press body; and
each of said engaging members has an inclined surface that is forwardly oriented and an engaging surface that is rearwardly oriented.
