Description

Technical Field

[0001] The utility model belongs to the field of communication, and particularly relates to an improved structure of a lensless optical fiber pigtail with simple operation, high efficiency, high yield rate and low production cost. Background Art

[0002] The lensless optical fiber pigtail (as shown in Figure 3 ) includes an optical fiber ferrule and a metal tube body. The maximum outer dimension of the optical fiber ferrule is 2.9 mm, while the inner diameter of the top opening of the metal tube body is only 2.8 mm. During assembly, workers need to first pre-insert the ferrule, then use a pneumatic tooling to press the ferrule into the designed position, and finally apply glue for fixation. At the same time, two narrow heat shrink tube fastening grooves are opened on the metal tube body. This traditional structure can meet certain usage requirements, but there are also relatively large defects. Since the inner diameter of the metal tube body is small, it is necessary to first insert and then press it with pneumatic tooling, which is troublesome to operate, has low efficiency, high labor intensity, high labor cost, low yield rate, long processing cycle for opening two narrow grooves, high production cost, and cannot effectively meet the usage requirements.

[0003] The technical problem to be solved by the utility model is to provide an improved structure of a lensless optical fiber pigtail that can be directly inserted and then glued for fixation, has simple operation, high efficiency, low labor intensity, low labor cost, high yield rate, short processing cycle for opening a wide groove, low production cost, and can effectively meet the usage requirements. Content of the Utility Model

[0004] In order to solve the problems in the above-mentioned prior art, such as small inner diameter of the metal tube body, need to be inserted first and then pressed with pneumatic tooling, troublesome operation, low efficiency, high labor intensity, high labor cost, low yield rate, long processing cycle for opening two narrow grooves, high production cost, and inability to effectively meet the usage requirements, the utility model adopts the following technical solutions:

[0005] The utility model provides an improved structure of a lensless optical fiber pigtail, which includes an optical fiber ferrule and a metal tube body. The maximum outer dimension of the optical fiber ferrule is 2.9 mm, the inner diameter of the top opening of the metal tube body is 3 mm, the optical fiber ferrule is inserted into the top opening of the metal tube body and glued for fixation, and a wide heat shrink tube fastening groove is opened in the middle of the metal tube body.

[0006] The beneficial effects of the utility model are as follows: the inner diameter of the metal tube body becomes larger, and it can be directly inserted and then glued for fixation, with simple operation, high efficiency, low labor intensity, low labor cost, high yield rate, short processing cycle for opening a wide groove, low production cost, and can effectively meet the usage requirements.

[0009] Figure 3 This is the structural schematic diagram of a traditional product. Specific embodiments

[0010] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0011] Please refer to Figure 1 , an improved structure of a lensless pigtail, comprising an optical fiber ferrule 1 and a metal tube body 2. The maximum outer dimension of the optical fiber ferrule 1 is 2.9 mm, and the inner diameter of the top opening of the metal tube body 2 is 3 mm. The optical fiber ferrule 1 is inserted into the top opening of the metal tube body 2 and fixed by dispensing glue (as Figure 2 shown). The size of the opening of the metal tube body is larger, and it can be directly inserted into the predetermined position without pneumatic tooling pressing. The operation is simple. A heat shrinkable tube fastening wide groove 21 is opened in the middle of the metal tube body 2. One wide groove can meet the requirements. The processing is simple and the cycle is short, effectively meeting the use requirements.

[0012] The beneficial effects of the present utility model are as follows: The inner diameter of the metal tube body becomes larger and can be directly inserted and fixed by dispensing glue. The operation is simple, the efficiency is high, the labor intensity is small, the labor cost is low, the yield rate is high, the processing cycle of opening one wide groove is short, the production cost is low, and the use requirements are effectively met.

[0013] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present utility model.
