Problems solved by technology

The ceramic ferrule in the prior art is a cylinder made of ceramics. The end of the cylinder has chamfers and an optical fiber hole is arranged in the cylinder along the long axis. After the fiber optic ceramic ferrule is chamfered and the end face is ground, the fiber optic ceramic ferrule is manually assembled with the metal parts. Since the fiber optic ceramic ferrule is a cylinder, there is no position that can be positioned, and there is no matching positioning device. The production process often suffers from low production efficiency and high scrap rate due to inaccurate positioning

Embodiment 1

[0053] The manufacturing process of the optical fiber adapter in this embodiment includes the following main steps:

[0054] (1) Cutting and chamfering: use a chamfering machine to cut and chamfer the ceramic ferrule;

[0055] (2) Put the ceramic ferrule into the fixture and lock it, and place it on the grinding machine. The grinding wheel of the grinding machine cuts a ferrule milling plane at the chamfer of the ceramic ferrule, and the ferrule milling plane is parallel to the central axis of the ferrule;

[0056] (3) 1-angle positioning of the end face: insert one end of the ceramic ferrule into the ferrule placement hole of the fixture of the grinder, and place the milling flat mouth of the ceramic ferrule outward, insert the insert towards the milling flat mouth and insert it into the top ferrule for milling The plane rotates the ferrule into place;

[0057] When the insert piece is inserted into the fixture, the insert piece touches the milling flat mouth of the ceramic ...

Embodiment 2

[0070] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features that are not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that in steps (4) and (6), the slope of the bevel made by grinding is 4° to 12°, and the bevel with different slopes can be made according to the requirements of the optical fiber adapter , which can be 4°, 5°, 8°, 9°, 12° and other degrees. When it is necessary to make a Sc Apc adapter, the angle of the bevel is set to 8°.

[0071] The glue injection position in step (8) is the groove between the ceramic ferrule and the metal piece.

[0072] In step (10), the baking temperature is 115±5° C., and the baking time is 50±10 minutes. In this embodiment, the baking temperature is 115° C., the baking time is 50 minutes, and the baking equipment is an industrial oven.

Embodiment 3

[0074] The main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, and the features not explained in this embodiment are explained in Embodiment 1 or Embodiment 2, and will not be repeated here. In this embodiment, the positioning spacer includes a fixed part and two elastic parts. One end of each elastic part is fixed to the disc, and the other end can be locked to the fixed part by a screw. Adjusting the tightness of the screw can adjust the positioning The length and angle of the spacer allow the fixture to meet the processing requirements of different specifications of ceramic ferrules.

Abstract

The invention discloses a fiber optic adapter manufacturing process, a fixture and a positioning adjustment device. Compared with the prior art, the process of the present invention has the steps of milling flat opening, end face positioning and positioning adjustment after glue injection, and the end face positioning by using the milling flat mouth can be quickly and easily Precisely locate the angle of the ceramic ferrule to ensure the grinding angle at both ends of the ceramic ferrule. Positioning adjustment by using the milled flat opening can quickly and accurately adjust the positional relationship between the milled flat opening and the metal part socket before the glue is cured, thereby adjusting the positional relationship between the slope of the ceramic ferrule and the metal part socket (also called the metal part milled flat port). Compliant with the standard, so it has high efficiency in docking and coupling, and has good anti-reflection effect.

Description

technical field [0001] The invention relates to the technical field of optical fiber adapters, in particular to a manufacturing process, a fixture and a positioning adjustment device of an optical fiber adapter. Background technique [0002] Fiber optic adapters are the most used optical passive components in fiber optic communication systems. Most fiber optic adapters are composed of three parts: two fiber optic connectors and a coupler. Two fiber optic connectors fit into the two fiber ends; the coupler acts as an alignment sleeve. In addition, the coupler is mostly equipped with metal or non-metallic flanges to facilitate the installation and fixation of the adapter. Optical fiber adapters with different interface types can be inserted at both ends of the optical fiber adapter to realize the conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO, E2000, etc. It is widely used in optical fiber distribution frames (ODF), optical fiber communication equip...
