[0002] The traditional four-core optical fiber ferrule uses a V-shaped groove to install the optical fiber at the lower end of the substrate, and the optical fiber is placed in the V-shaped groove and then pressed by a presser part and bonded by an adhesive. Since the ferrule is The V-shaped groove and the cover plate are composed of two parts, so it is difficult to operate the ferrule when it is introduced into the connector, and it is easy to cause the cover plate to fall from the ferrule, and the ferrule is prone to loosening after it is installed in the connector. affect signal transmission

Embodiment
[0025] Example: such as Figure 1 to Figure 3 As shown, the present invention is a four-core optical fiber ferrule, which includes a ferrule body 1, the ferrule body 1 is a cuboid, the rear end surface of the ferrule body 1 is provided with an installation cavity 2, and the Four optical fiber through-holes 3 are set through the ferrule body 1. The ferrule body 1 is provided with a square dispensing port 4 communicating with the installation cavity 2. The front end of the ferrule body 1 is provided with a The boss 5, the upper end of the boss 5 is an inclined plane, the lower end of the boss 5 is provided with a positioning step 6 consistent with the width of the ferrule body 1, and the positioning step 6 plays a fixed role to prevent the four-core optical fiber ferrule from Displacement occurs.
[0026] Corresponding to the fiber through hole 3 in the installation cavity 2, there are the same number of fiber positioning holes 7 as the fiber through hole 3, and the four fiber ...

Abstract
The invention discloses a four-core optical fiber ferrule, which comprises a cuboid ferrule body. The rear end surface of the ferrule body is provided with a mounting cavity; four optical fiber through holes passing through the ferrule body are arranged in the mounting cavity; the ferrule body is provided with a square dispensing port communicated with the mounting cavity; the front end surface of the ferrule body is provided with a boss facilitating insertion; the upper end of the boss is an inclined plane; and the lower end of the boss is provided with a positioning step with the consistent width with the ferrule body. The invention also discloses a four-core optical fiber ferrule manufacturing method. Problems that the traditional four-core optical fiber ferrule has multiple assemblies, the operation is troublesome, the assemblies are easy to fall, displacement is likely to happen and the like are solved, and a phenomenon of instable signal transmission is further improved.
Description
technical field [0001] The invention relates to the technical field of optical fiber ferrules, in particular to a four-core optical fiber ferrule and a preparation method for the four-core optical fiber ferrule. Background technique [0002] The traditional four-core optical fiber ferrule uses a V-shaped groove to install the optical fiber at the lower end of the substrate, and the optical fiber is placed in the V-shaped groove and then pressed by a presser part and bonded by an adhesive. Since the ferrule is The V-shaped groove and the cover plate are composed of two parts, so it is difficult to operate the ferrule when it is introduced into the connector, and it is easy to cause the cover plate to fall from the ferrule, and the ferrule is prone to loosening after it is installed in the connector. affect signal transmission. Contents of the invention [0003] The object of the present invention is to provide a four-core optical fiber ferrule to solve the above problems. ...
