Abstract
A universal optical fiber connector comprises a ferrule for supporting an optical fiber and having an axis extending in an axial direction of the ferrule, a biasing member comprised of a synthetic elastic material for biasing the ferrule in the axial direction, and a securing member for securing the biasing member between the securing member and the ferrule. A connecting member is adapted to receive the ferrule for connection to another ferrule through the connecting member.
Claims20
A universal optical fiber connector comprising:
- a ferrule for supporting an optical fiber and having an axis extending in an axial direction of the ferrule;
- a first tubular member connected to the ferrule and having a protrusion disposed at an end portion thereof;
- a biasing member disposed over the first tubular member and comprised of a synthetic elastic material for biasing the ferrule in the axial direction;
- a securing member for securing the biasing member between the securing member and the ferrule, the securing member comprising a second tubular member having a hole for engagement with the protrusion of the first tubular member to firmly hold the second tubular member in place so as to firmly support the biasing member, the protrusion of the first tubular member comprising a flexible engaging portion which protrudes radially from the first tubular member and which undergoes deformation in a radial direction of the second tubular member to engage the hole of the second tubular member;
- and
- a connecting member for receiving the ferrule for connection to another ferrule through the connecting member.
A ferrule holding device comprising:
- at least one ferrule for supporting an optical fiber and having an axis extending in an axial direction of the ferrule;
- a first tubular member connected to the ferrule and having a protrusion disposed at an end portion thereof;
- a biasing member disposed over the first tubular member and comprised of a synthetic elastic material for biasing the ferrule in the axial direction;
- and
- a securing member for securing the biasing member between the securing member and the ferrule, the securing member comprising a second tubular member having a hole for engagement with the protrusion of the first tubular member to firmly hold the second tubular member in place so as to firmly support the biasing member, the protrusion of the first tubular member comprising a flexible engaging portion which protrudes radially from the first tubular member and which undergoes deformation in a radial direction of the second tubular member to engage the hole of the second tubular member.
