MT insertion core structure

Abstract

The invention relates to the technical field of optical fiber connector components, in particular to an MT insertion core structure, which comprises an insertion core body, an optical fiber cladding channel is formed in the front section of the interior of the insertion core body and used for positioning and fixing an optical fiber cladding, and front-back guide holes are formed in the left end and the right end of the insertion core body. The MT insertion core structure is characterized in that: an optical fiber coating layer channel is formed in the rear section in the insertion core body and used for fixing an optical fiber coating layer, guide transition is formed between the optical fiber cladding layer channel and the optical fiber coating layer channel, the top and the bottom of theinsertion core body are closed, a dispensing opening is formed in the tail end in the insertion core body , and a dispensing window is removed from the insertion core body, the top and the bottom areclosed, so that the strength is higher; the optical fiber cladding channel and the optical fiber coating layer channel are arranged in the insertion core body, the optical fiber cladding channel fixes the optical fiber cladding, the optical fiber coating layer channel fixes the optical fiber coating layer, optical fibers can be well protected, guide transition exists between the channels, opticalfiber protection is enhanced, and product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber connector components, in particular to an MT ferrule structure. Background technique [0002] MT ferrule is a connection part used for optical fiber connectors, usually used as the connector of optical fiber connectors, with channels inside for fixing optical fibers, and guide holes or guide posts on both sides as docking references. Such as Chinese patent: a MT ferrule, patent number: 2017200797198. The usual structure of the MT ferrule shown in 2017200797198 is that the inner front end is provided with a fiber guide groove for fixing the fiber cladding, and the inner rear end is provided with a hollow part for It is connected with the tail pipe, with a dispensing window on the top for dispensing and fixing the fixed optical fiber. [0003] However, this conventional structure has several defects: 1. The existence of the dispensing window makes the thickness of the optical fiber, especiall...

Problems solved by technology

[0003] However, this conventional structure has several defects: 1. The existence of the dispensing window makes the thickness of the optical fiber, especially the adhesive layer around the junction point of the optical fiber cladding and the optical fiber coating layer, uneven, which has a negative impact on reliability; 2. .The existence of the dispensing window causes the ferrule to have weak lateral strength, making it easy to damage during production and use; 3. The length of the fiber guide groove is not enough, and it is difficult to insert the fiber into the fiber, so a microscope is needed; 4. The end is reserved Through the hollow space of the tail pipe, the edge wall thickness of the guide holes at both ends is not enough, the strength becomes weak, and it is easy to break
