Description

Technical Field:

[0001] The utility model relates to the field of production and manufacturing of communication equipment, and particularly relates to an integrated joint shank. Background Art:

[0002] Optical fiber is the abbreviation of optical waveguide fiber, which is a fiber made of glass or plastic and can be used as an optical conduction tool. The transmission principle is total internal reflection of light.

[0003] An optical fiber connector permanently or separably connects two optical fibers together and has a connection part with a protection component. The optical fiber connector is the end device of the optical fiber.

[0004] The shank is a structure inside the connector used to sleeve the optical fiber and keep the optical fiber fixed inside.

[0005] Inside a conventional optical fiber connector, multiple single parts such as a ceramic ferrule, a shank, and a spring are fixed together with a housing, which cannot meet the usage requirements in special occasions. For example, when passing through a pipe, due to different sizes, the optical fiber with a connector cannot pass through the pipe, and when the connector needs to be disassembled.

[0006] Therefore, a shank that can be easily installed and disassembled while maintaining the straightness of the internal optical fiber is needed. Summary of the Utility Model:

[0007] The purpose of the utility model is to provide an integrated joint shank.

[0008] The utility model is implemented by the following technical solutions:

[0009] An integrated joint shank includes a shank, a sleeve and a spring are sleeved on the shank, a ferrule is screwed at one end of the shank, a tapered ring is fixedly connected to one end of the ferrule, a jack is arranged inside the shank, the jack is in a horn shape, an extrusion ring is inserted into the jack, a rubber pad is attached to the inner wall of the extrusion ring, a positioning ring is fixedly connected to one end of the extrusion ring, and one end of the extrusion ring extends into the opening of the tapered ring.

[0010] Preferably, the diameter of the sleeve is the same as the outer diameter of the spring.

[0011] The advantages of the utility model: The jack is arranged in a horn shape, which is convenient for insertion. During the insertion process, the positioning ring ensures the straightness of the optical fiber, and after the positioning ring contacts the tapered ring as it extends, it is automatically aligned, ensuring that the optical fiber can conduct linearly, reducing optical signal loss, and the operation is simple and convenient. In this way, when performing pipe-passing work, it can be easily disassembled and installed, with a wide application range and strong practicability. Description of the Drawings:

[0012] Figure 1 is a perspective view of the structure of the utility model;

[0013] Figure 2 is an exploded view of the structure of the present utility model;

[0014] Figure 3 is a schematic diagram of the connection between the ferrule and the tail handle in the structure of the present utility model.

[0015] In the figure: tail handle 1, ferrule 2, sleeve 3, spring 4, jack 5, extrusion ring 6, conical ring 7, positioning ring 8. Specific implementation method:

[0016] As Figures 1 to 3 shown, an integrated joint tail handle includes a tail handle 1. A sleeve 3 and a spring 4 are sleeved on the tail handle 1. One end of the tail handle 1 is screwed with a ferrule 2. One end of the ferrule 2 is fixedly connected with a conical ring 7. A jack 5 is arranged inside the tail handle 1. The jack 5 is in a horn shape. An extrusion ring 6 is inserted into the jack 5. A rubber pad is attached to the inner wall of the extrusion ring 6. One end of the extrusion ring 6 is fixedly connected with a positioning ring 8. One end of the extrusion ring 6 extends into the opening of the conical ring 7. When installing, first screw the ferrule 2 with the tail handle 1. After installation, first put the extrusion ring 6 on the optical fiber and move it to an appropriate distance to ensure that the exposed end of the optical fiber can enter the ferrule 2, and then insert it into the jack 5. The jack 5 is set in a horn shape to facilitate insertion. During the insertion process, the positioning ring 8 ensures the straightness of the optical fiber. And as it extends in, after the positioning ring 8 contacts the conical ring 7, it is automatically aligned to ensure that the optical fiber can conduct linearly, reducing the loss of optical signals. The operation is simple and convenient. In this way, when carrying out pipe threading work, it can be easily disassembled and installed, with a wide range of applications and strong practicability.

[0017] The diameter of the sleeve 3 is the same as the outer diameter of the spring 4 to ensure that the spring 4 will not fall off.

[0018] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
