Abstract
The utility model relates to the technical field of optical fiber connectors, in particular to an MT ferrule, which is characterized in that a ferrule sheath penetrates through an optical fiber after soft glue is dispensed, a soft glue sealing protective layer is formed on the outer side of the end part of the ferrule sheath, and the glue sealing protective layer is arranged in a groove of the ferrule after the ferrule sheath and the ferrule are assembled and used for preventing epoxy glue from entering a bending-resistant area of the ferrule sheath, and has the advantages that: a soft rubber sealing protective layer is formed at the end part of the ferrule sheath, so that epoxy glue can be prevented from flowing into the ferrule sheath during heating and curing, and breakage and failure during bending of external optical fibers are avoided.
Description
Technical Field
The utility model relates to the technical field of optical fiber connectors, in particular to an MT (multi-terminal) ferrule.
Background
The MT insertion core is an optical fiber connector and consists of an insertion core assembly, an optical fiber and a ferrule sheath, wherein the ferrule sheath is matched with the insertion core assembly after the optical fiber passes through the ferrule sheath. The upper part of the ferrule assembly is provided with a notch for injecting epoxy glue. However, epoxy glue is hard and easily flows into the bending-resistant region of the ferrule sheath during heat curing, which causes root fracture when the external optical fiber is bent.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provides an MT ferrule.
In order to achieve the above object, an MT ferrule is designed, including an optical fiber; the ferrule sheath is sleeved outside the optical fiber, the ferrule is provided with an optical fiber channel in the ferrule, the ferrule is connected with the ferrule sheath in a matching way, one side of the upper part of the ferrule is provided with a notch, the notch is communicated with the optical fiber channel and is used for injecting epoxy glue, the ferrule sheath penetrates into the ferrule sheath after the soft glue is applied to the optical fiber, a soft glue sealing protective layer is formed outside the end part of the ferrule sheath, and after the ferrule sheath is assembled with the ferrule, the glue sealing protective layer is arranged in the notch of the ferrule and is used for preventing the epoxy glue from entering into a bending area of the ferrule sheath.
Compared with the prior art, the utility model has the advantages that: a soft rubber sealing protective layer is formed at the end part of the ferrule sheath, so that epoxy glue can be prevented from flowing into the ferrule sheath during heating and curing, and breakage and failure during bending of external optical fibers are avoided.
