An optical fiber connector includes a ferrule, a fastening tube, and a cover plate. The ferrule includes a through hole and a breach. Front and rear parts of the through hole respectively include a pre-embedded optical fiber and a field optical fiber. A joint of the two optical fibers is located at the breach. A part of the through hole is exposed in the breach. The fastening tube includes a ferrule accommodating portion accommodating a part of the ferrule on which the breach is disposed, and an opening disposed thereon. The opening connects the ferrule accommodating portion, and is positionally corresponding to the breach. The cover plate passes through the opening, is disposed in the breach, and presses the joint. The ferrule is easily machined and can adopt a material hardly influenced by environment temperature. The joint is fixed, and an amount of joint loss is stable. |

1. An optical fiber connector comprising:
a ferrule comprising a through hole and a breach, with the breach disposed on a wall of the ferrule, with a pre-embedded optical fiber pre-embedded in a front part of the through hole of the ferrule, with a field optical fiber being inserted into a rear part of the through hole of the ferrule, with a joint of the pre-embedded optical fiber and the field optical fiber located at the breach, with a part of the through hole of the ferrule being exposed in the breach; a fastening tube comprising a ferrule accommodating portion and an opening, with the ferrule accommodating portion accommodating a part of the ferrule on which the breach is disposed, with the opening of the fastening tube being disposed on a wall of the fastening tube, connecting the ferrule accommodating portion, and being positionally corresponding to the breach; a cover plate passing through the opening and disposed in the breach, with the cover plate pressing the joint of the pre-embedded optical fiber and the field optical fiber; and a compression sleeve slideably received on the fastening tube for movement parallel to the through hole, with the cover plate comprising a bump disposed on an upper side thereof, wherein the compression sleeve encloses a part of the fastening tube on which the opening is disposed, and wherein an inner wall of the compression sleeve presses the bump of the cover plate to make a lower side of the cover plate tightly press the joint of the pre-embedded optical fiber and the field optical fiber. |
