Abstract

An optical fiber connector includes a main body ( 1 ), a sleeve ( 2 ), and a plug ( 3 ). The main body ( 1 ) includes a first cube and a second cube that are formed by means of injection molding, where a first cavity ( 1 o ) is disposed inside the first cube, and the first cavity ( 1 o ) is used to adapt to an optical fiber sub-assembly inserted from a first end face of the first cube; at least two hook-like structures ( 1 n ) are formed, by means of injection molding, on the first cube extending from a second end face that is parallel to the first end face into the first cavity ( 1 o ), and the hook-like structures ( 1 n ) are used to tightly lock the optical fiber sub-assembly when the optical fiber sub-assembly is inserted from the first end face.

First claim

What is claimed is:

1. An optical fiber connector comprising:
a sleeve;
a plug;
a main body coupled to the plug, wherein the main body comprises:
a first cube comprising:
a first end face;
a second end face parallel to the first end face; and
a first cavity configured to adapt to an optical fiber sub-assembly inserted from the first end face; and

a second cube comprising:
a first part accommodated in the first cavity and fastened to the first cube;
a second part extending along an axial direction and protruding on the first cube, wherein the axial direction is from the first end face to the second end face;
a second cavity traversing along the axial direction and configured to accommodate the sleeve, wherein the sleeve is disposed within the second cavity;
a lip at a first end of the second cavity, wherein the lip is configured to prevent the sleeve from being removed from the first end face of the first cube; and
a third cavity having a first end at a second end of the second cavity that is opposite the first end of the second cavity, wherein the third cavity comprises a first notch and a square hole configured to lock the plug when the plug is inserted into the third cavity; and

hook-like structures formed on the first cube and extending from the second end face into the first cavity,
wherein each of the hook-like structures includes a cantilever, and
wherein the hook-like structures are configured to tightly lock the optical fiber sub-assembly when the optical fiber sub-assembly is inserted from the first end face.

2. The optical fiber connector of claim 1 , wherein the second cavity is cylindrical, wherein inner surfaces of the first cube and the second cube radially enclose the second cavity, wherein the optical fiber connector further comprises a guiding gap on an upper wall outside the first cube, and wherein the guiding gap is configured to limit an inserting direction of the optical fiber sub-assembly.

3. The optical fiber connector of claim 1 , further comprising:
side walls outside the first cube;
a lower wall outside the first cube; and
a recess disposed on the side walls and the lower wall.

4. The optical fiber connector of claim 1 , further comprising:
two side surfaces of the first cube; and
stub wings symmetrically disposed on the two side surfaces.

5. The optical fiber connector of claim 1 , wherein the third cavity further comprises a second notch configured to further lock the plug when the plug is inserted into the third cavity.

6. The optical fiber connector of claim 1 , wherein the first cube further comprises a root part, wherein the second cube comprises an upper surface and a lower surface, and wherein the optical fiber connector further comprises two grooves disposed on the upper surface and the lower surface and close to the root part.

7. The optical fiber connector of claim 6 , further comprising a mounting accessory fastened to the main body by the grooves.

8. The optical fiber connector of claim 7 , wherein the mounting accessory comprises a square hole and bosses, wherein the square hole comprises an interior, wherein the interior comprise a top and a bottom, and wherein the bosses are disposed at the top and the bottom and are configured to be installed as a whole with the grooves by fastening.

9. An optical fiber connector component system comprising:
a panel; and
optical fiber connectors mounted on the panel,
wherein each optical fiber connector comprises a sleeve, a plug, a main body coupled to the plug, and hook-like structures,
wherein the main body comprises:
a first cube comprising:
a first end face;
a second end face parallel to the first end face; and
a first cavity configured to adapt to an optical fiber sub-assembly inserted from the first end face; and

a second cube comprising:
a first part accommodated in the first cavity and fastened to the first cube;
a second part extending along an axial direction and protruding on the first cube, wherein the axial direction is from the first end face to the second end face;
a second cavity traversing along the axial direction, wherein the sleeve is disposed within the second cavity; and
a third cavity, wherein the third cavity comprises a first notch and a square hole configured to lock the plug when the plug is inserted into the third cavity,

wherein the hook-like structures are formed on the first cube and extend from the second end face into the first cavity,
wherein each of the hook-like structures includes a cantilever, and
wherein the hook-like structures are configured to lock the optical fiber sub-assembly when the optical fiber sub-assembly is inserted from the first end face.

10. The system of claim 9 , wherein each optical fiber connector further comprises a guiding gap on an upper wall outside the first cube, and wherein the guiding gap is configured to limit an inserting direction of the optical fiber sub-assembly.

11. The system of claim 9 , wherein each optical fiber connector further comprises:
side walls outside the first cube;
a lower wall outside the first cube; and
a recess disposed on the side walls and the lower wall.

12. The system of claim 9 , wherein each optical fiber connector further comprises:
two side surfaces of the first cube; and
stub wings symmetrically disposed on the two side surfaces.

13. The system of claim 9 , wherein each optical fiber connector further comprises:
a side surface of the second cavity; and
a second notch disposed on the side surface.

14. The system of claim 9 , wherein the first cube further comprises a root part, wherein the second cube comprises an upper surface and a lower surface, and wherein each optical fiber connector further comprises two grooves disposed on the upper surface and the lower surface and close to the root part.

15. The system of claim 14 , wherein each optical fiber connector further comprises a mounting accessory fastened to the main body by the grooves.

16. The system of claim 15 , wherein the mounting accessory comprises a square hole and bosses, wherein the square hole comprises an interior, wherein the interior comprises a top and a bottom, and wherein the bosses are disposed at the top and the bottom and are configured to be installed as a whole with the grooves by fastening.
