Optical fiber connector

Abstract

A fiber optic connector includes a housing, a sleeve, a retaining element, and a tail sleeve. At least one optical fiber is fixed within the sleeve, which is assembled within the housing, with a portion of the sleeve extending from a first end of the housing. The end of the optical fiber away from the sleeve extends from a second end of the housing, the first and second ends being opposite ends of the housing. The retaining element is sleeved onto the outside of the housing and has a first retaining portion. The tail sleeve is sleeved onto the outside of the housing from the second end to cover the second end and the optical fiber extending from the second end. The tail sleeve has a second retaining portion that engages with the first retaining portion, allowing the tail sleeve to be subjected to force and to actuate the retaining element, thereby pulling the fiber optic connector out of the adapter.

Claims

1. An optical fiber connector, comprising: case; A ferrule, which has at least one optical fiber fixed inside, is assembled inside the housing and a portion of the ferrule extends out of the housing from a first end of the housing. The end of the optical fiber away from the ferrule extends out from a second end of the housing. The first end and the second end are opposite ends of the housing. A retaining member is fitted onto the outside of the housing and has a first retaining portion. A tail sleeve is fitted onto the outside of the housing from the second end to cover the second end and the optical fiber extending from the second end. The tail sleeve has a second retaining portion that snaps into the first retaining portion so that the tail sleeve is adapted to bear force and move the retaining member to pull the optical fiber connector out of the adapter.

2. The fiber optic connector as claimed in claim 1, wherein the first retaining portion is one of the retaining protrusion and the retaining hole, and the second retaining portion is the other of the retaining protrusion and the retaining hole.

3. The fiber optic connector as claimed in claim 2, wherein the retaining member or the tail sleeve has a spring arm structure, and the retaining protrusion is at the tail end of the spring arm structure.

4. The fiber optic connector as claimed in claim 2, wherein a first side of the retaining protrusion is a gentle slope and a second side of the retaining protrusion is a cliff, such that the retaining hole moves along the gentle slope in a first direction until it falls down the cliff and then engages with the retaining protrusion in a second direction, wherein the first direction and the second direction are opposite to each other.

5. The fiber optic connector as claimed in claim 1, wherein the tail sleeve has a tapered surface that gradually tapers inward away from the housing, and the tail sleeve also has a plurality of force-applying grooves located on the tapered surface.

6. The fiber optic connector as claimed in claim 1, wherein the retaining member, when combined with the housing, forms a pair of receiving chambers located on opposite sides of the housing, and the fiber optic connector further includes a pair of first elastic members located in the pair of receiving chambers, and each of the first elastic members abuts between the housing and the retaining member.

7. The fiber optic connector as claimed in claim 6, wherein, with the housing as a reference, the retaining member compresses and deforms the pair of first elastic members and accumulates elastic force when the retaining member moves in a second direction, and when the elastic force is released, the retaining member is driven to move in a first direction opposite to the second direction, and the second direction is the direction in which the fiber optic connector is pulled out of the adapter.

8. The fiber optic connector as claimed in claim 1, wherein the snapping direction of the first and second latching portions is consistent with the direction in which the fiber optic connector is pulled out of the adapter.

9. The fiber optic connector as claimed in claim 1 further includes a receiving block and a fixing tube, the front surface of the receiving block extending into two side arms that snap into the inner wall of the housing, the rear surface of the receiving block extending into a screw tube, the fixing tube being screwed into the screw tube, the outer wall of the fixing tube abutting against the inner wall of the tail sleeve, and the optical fiber passing through the receiving block, the fixing tube and the tail sleeve in sequence.

10. The fiber optic connector as claimed in claim 9 further includes a second elastic member disposed between the two side arms and abutting between the two side arms and the sleeve, wherein the two side arms each have a step to abut one end of the second elastic member.

11. The fiber optic connector as claimed in claim 10 further includes a housing disposed within the housing and located between the receiving block and the sleeve, wherein the second elastic member abuts between the two steps of the two side arms and the housing.

12. The fiber optic connector as claimed in claim 11, wherein the housing further comprises two guide pins that pass through and partially protrude from the sleeve and the housing as the housing abuts against the sleeve.

13. The fiber optic connector as claimed in claim 1, wherein the tail sleeve, the fastener, the housing, and the sleeve are in a layered, overlapping structure from the outside in.

14. The fiber optic connector as claimed in claim 1, wherein the tail sleeve includes a head section and a tail section, wherein the head section has the second retaining portion and is stacked over the housing and the retaining member, and the tail section is tapered relative to the head section to cover the optical fiber extending from the housing.
