Abstract

An optical fiber joint includes: an optical fiber extending out of the optical cable is held in the cavity, one end of the inner sleeve element is fixed at the optical cable, and a sleeve is placed at the other end; and an outer sleeve element, the outer sleeve element is sleeved onto an outer side of the inner sleeve element; the sleeve of the inner sleeve element at least partially protrudes out of the outer sleeve element, a tail end of the sleeve protruding out of the outer sleeve element has an opening, so that the tail end of the sleeve forms a C-shaped section. Based on the foregoing technical solutions, the optical fiber connector according to the embodiments of the present disclosure is seamlessly connected to a C-shaped slot of an optical fiber adapter by using the sleeve having the C-shaped opening of the optical fiber joint.

First claim

What is claimed is:

1. An optical fiber adapter, comprising:
a socket is placed at one end of the optical fiber adapter, wherein a cavity configured to hold an optical fiber and a slot are placed in the socket;
wherein the cavity is located in a middle part of the socket; and
the slot surrounds on a periphery of the cavity, and a locating key is placed in the socket, so that the slot forms a C-shaped section;
wherein the slot having the C-shaped section is configured to hold a C-shaped tail end of a sleeve of an optical fiber joint that matches the optical fiber adapter.

2. The optical fiber adapter according to claim 1 , wherein the locating key is configured to connect to an opening of a sleeve of an optical fiber joint that matches the optical fiber adapter.

3. The optical fiber adapter according to claim 1 , wherein a width of the locating key is equivalent to a width of an opening of the optical fiber joint.

4. An optical fiber connector, comprising an optical fiber joint and an optical fiber adapter, wherein
the optical fiber joint comprises: an optical cable; an inner sleeve element with a cavity inside, wherein an optical fiber extending out of the optical cable is held in the cavity, one end of the inner sleeve element is fixed at the optical cable, and a sleeve is placed at another end; and an outer sleeve element, wherein the outer sleeve element is sleeved onto an outer side of the inner sleeve element, and the outer sleeve element is capable of axially rotating around the sleeve; wherein the sleeve of the inner sleeve element at least partially protrudes out of the outer sleeve element, and a tail end of the sleeve protruding out of the outer sleeve element has an opening, so that the tail end of the sleeve forms a C-shaped section, and the sleeve having a C-shaped opening is connected to a C-shaped slot of the optical fiber adapter; and
a socket is placed at one end of the optical fiber adapter, wherein another cavity configured to receive an optical fiber and a slot are placed in the socket, wherein the cavity is located in a middle part of the socket, the slot surrounds on a periphery of the cavity, and a locating key is placed in the socket, so that the slot forms another C-shaped section.

5. The optical fiber connector according to claim 4 , wherein an inner wall of the outer sleeve element of the optical fiber joint has at least one projection.

6. The optical fiber connector according to claim 4 , wherein at least one sliding slot is placed on an outer surface of the socket of the optical fiber adapter.

7. The optical fiber connector according to claim 5 , wherein the optical fiber joint is inserted into the optical fiber adapter, and the at least one projection is connected to at least one sliding slot.

8. The optical fiber adapter according to claim 2 , wherein a width of the locating key is equivalent to a width of the opening of the optical fiber joint.

9. The optical fiber connector according to claim 6 , wherein the optical fiber joint is inserted into the optical fiber adapter, and a projection is connected to the sliding slot.
