Abstract
Description
Technical Field
[0001] The present application relates to the field of fiber optic connectors, and in particular to a wall-penetrating fiber optic connector. Background Art
[0002] A fiber optic connector is an end device of an optical fiber, which is used to connect two optical fibers and protect the connection part of the components. During the laying process of the optical fiber, it is sometimes necessary to pass it through a wall. However, for the fiber optic connectors in the prior art, their ends are usually cylindrical. For a cylindrical fiber optic connector, it is difficult to penetrate the wall and is easily damaged, resulting in a low laying efficiency of the fiber optic connection; at the same time, there will be a large amount of dust in the wall hole during wall penetration, and these dusts will accumulate on the fiber optic connector, which will not only affect the layout of the fiber optic connector, but also the accumulated dust is likely to penetrate into the fiber optic connector, resulting in a large attenuation of the optical signal or no light transmission. Summary of the Utility Model

The wall-penetrating module includes a wall-penetrating part, and the diameter of the wall-penetrating part gradually decreases along the direction away from the connector body.
[0006] By adopting the above technical solution, the diameter of the wall-penetrating part gradually decreases to form a conical end. The conical end can quickly penetrate the wall hole, reducing the difficulty of the fiber optic connector in penetrating the wall and effectively improving the laying efficiency of the optical fiber.

[0010] By adopting the above technical solution, it can be avoided that the wall-penetrating part breaks or is damaged during wall penetration due to the overly sharp end.

[0013] In a specific feasible embodiment, the wall-penetrating portion and the dust-proof sleeve are integrally formed.
[0014] By adopting the above technical solution, it can prevent dust from penetrating into the connector body through the gap between the wall-penetrating portion and the dust-proof sleeve.
[0015] In a specific feasible embodiment, the connector body further includes a hollow connection shell. The pull cap is accommodated in the connection shell. The dust-proof sleeve is inserted into one end of the connection shell. A limit ring is provided on the dust-proof sleeve, and a first limit groove is annularly provided on the inner wall of the connection shell. The limit ring is embedded in the first limit groove.
[0016] By adopting the above technical solution, it can prevent relative axial movement between the dust-proof sleeve and the connection shell, avoid the wall-penetrating module falling off the connector body during the wall-penetrating process, and improve the quality and efficiency of optical fiber laying.
[0017] In a specific feasible embodiment, a first limit plane is axially provided on the dust-proof sleeve, and a second limit plane is axially provided on the inner wall of the connection shell along its own axis. The first limit plane is in contact with the second limit plane.
[0018] By adopting the above technical solution, it can avoid relative rotation between the wall-penetrating module and the connector body and prevent the optical fiber from being bent or broken during the relative rotation of the wall-penetrating module and the connector body.
[0019] In a specific feasible embodiment, limit posts are respectively provided on two opposite sides of the pull cap, and second limit grooves are respectively opened on two opposite sides of the connection shell. The two limit posts are respectively slidably arranged in the two second limit grooves.
[0020] By adopting the above technical solution, it can avoid relative rotation between the pull cap and the connection shell and prevent the optical fiber from being bent or broken during the relative rotation of the pull cap and the connection shell.
[0021] In a specific feasible embodiment, one end of the second limit groove has a notch for the limit post to enter.
[0022] By adopting the above technical solution, it is convenient for the relative assembly between the pull cap and the connection shell.

A pull cap 11 is provided at the end of the connector body 1, and the pull cap 11 is inserted into the dust-proof sleeve 22.

[0036] A first limiting plane (not shown in the figure) is axially provided on the dust-proof sleeve 22, and a second limiting plane (not shown in the figure) is axially provided on the inner wall of the connection shell 12. The first limiting plane and the second limiting plane are in contact with each other. The first limiting plane and the second limiting plane can limit each other, avoid relative rotation between the wall-piercing module 2 and the connector body 1, and prevent the optical fiber from being bent or broken during the relative rotation of the wall-piercing module 2 and the connector body 1.
[0037] In this embodiment, limiting posts 13 are respectively provided on two opposite sides of the pull cap 11, and second limiting grooves 122 are respectively formed on two opposite sides of the connection shell 12. The two limiting posts 13 are respectively slidably arranged in the two second limiting grooves 122.

[0039] In this embodiment, the connector body 1 further includes a ferrule 14, a support tube 15, a spring 16 and a tail handle 17. One end of the ferrule 14 is inserted into the pull cap 11, and a compression ring 18 is provided at the other end.
