Abstract

Embodiments of the present invention provide an optical fiber connector assembly, an optical fiber adapter, and an optical fiber connector to solve the problem of inconvenience in use caused by using a thread-locking manner in the prior art. The optical fiber connector, optical fiber adapter and optical fiber connector assembly provided in the present invention may be used as an outdoor connector to achieve plug and play. The optical fiber connector supports blind-mate, and the operation is convenient. Time taken to install and disassemble the optical fiber connector provided in the present invention is only ⅕ of the time taken to install and disassemble a common thread connector.

First claim

What is claimed is:

2 . The optical fiber connector assembly according to claim 1 , wherein the inner wall of the other end of the outer jacket element is provided with two opposite bumps.

3 . The optical fiber connector assembly according to claim 1 , wherein the inner wall of the other end of the outer jacket element is provided with a plurality of bumps along a axial direction of the outer jacket element.

4 . The optical fiber connector assembly according to claim 1 , wherein the at least one protection key comprises two protection keys, the two protection keys are disposed opposite to each other on two sides of the ferrule; sections of the two protection keys are completely symmetrical and the sections of the protection keys are of a D shape with different top and bottom widths; and the protection keys extend along an axial direction of the ferrule and one end of the ferrule away from the inner jacket element is retained between the two protection keys.

5 . The optical fiber connector assembly according to claim 4 , wherein one end of the protection key is provided with a stepped groove, and wherein the stepped groove is configured to be sleeved on a protection key of another optical fiber connector assembly.

6 . The optical fiber connector assembly according to claim 1 , wherein the elastic element is a spring, and wherein the elastic element is sleeved on the inner jacket element.

7 . The optical fiber connector assembly according to claim 6 , wherein the bump is a cylindrical bump.

8 . The optical fiber connector assembly according to claim 7 , wherein the optical fiber connector assembly comprises:
a connector assembly dust cap; one end of the connector assembly dust cap is formed with a connector assembly retaining cavity and the connector assembly retaining cavity extends along an axial direction of the connector assembly dust cap, wherein the connector assembly retaining cavity is formed with a first notch that matches the buckling elastic piece, wherein the at least one protection key comprises two protection keys, wherein the connector assembly retaining cavity receives the two protection keys and the ferrule, wherein a periphery of the connector assembly dust cap is formed with a first chute, wherein the first chute matches the bump, the first chute is of a spiral shape, the first chute extends from one end of the connector assembly dust cap along a axial direction of the connector assembly dust cap, and a rear end of extension of the first chute latches the bump.

9 . An optical fiber adapter comprising:
a socket, wherein the socket is formed with an optical fiber slot and two protection key slots, wherein the optical fiber slot and the two protection key slots extend along an axial direction of the socket, wherein the optical fiber slot is formed with a second notch, wherein the two protection key slots are located on two sides of the optical fiber slot, and wherein a periphery of the socket is formed with a second chute, wherein the second chute is of a spiral shape, wherein the second chute extends from one end of the socket along a axial direction of the socket, and a end of extension of the second chute is bent towards one end of the socket.

10 . The optical fiber adapter according to claim 9 , wherein the socket is of a cylindrical shape.

11 . The optical fiber adapter according to claim 10 , wherein a slot opening of the protection key slot is of a D shape with different top and bottom widths.

12 . The optical fiber adapter according to claim 10 , wherein the optical fiber adapter comprises an adapter dust cap, wherein one end of the adapter dust cap is formed with an adapter retaining cavity for receiving the optical fiber adapter, and wherein an inner wall of the adapter retaining cavity is provided with a bump and the bump is slideably connected in the second chute.

13 . The optical fiber adapter according to claim 10 , wherein an inner wall of the adapter retaining cavity is provided with two opposite bumps.

14 . An optical fiber connector comprising an optical fiber connector assembly and an optical fiber adapter that matches the optical fiber connector assembly, wherein the optical fiber connector assembly comprises:
