TECHNICAL FIELD

[0001] The utility model relates to the field of optical fiber communication technology, specifically relates to a wall -penetrating SC type optical fiber movable connector. BACKGROUND

[0002] FTTR (Fiber to the Room) is to extend the optical fiber from the communication base station to every corner in the home indoor, thereby providing the home user with the internet access service of extremely high speed.

[0003] The optical fiber replaces the network cable, realizes the interconnection with the home gateway through the deployment of optical networking terminal, combines double -frequency Wi -Fi, wi -Fi6 etc. Technology, guarantees the networking technology of whole house network coverage. The core principle of FTTR technology is to extend the optical fiber transmission to the specific area in the building, realizes through the characteristic of optical fiber transmission data.

[0004] FTTR technology usually includes OLT (optical line terminal), FOTN (optical fiber transmission network) and UE (user terminal). OLT extends to the user area through the optical fiber, and FOTN smoothly transmits the signal to the UE device, thereby establishing the high-speed broadband connection.

[0005] When the optical fiber replaces the network cable and is wired in the whole house, its use principle is same as the network cable wiring, needs to be led through the wall to each room, to the reserved optical network hole, so that the optical fiber product needs to have certain wall -penetrating bending resistance. However, the traditional SC type optical fiber movable connector does not have the ability of wall traction, when entering the house, in order to meet the wall -penetrating optical fiber not being damaged, generally adopts the optical cable to be introduced into each room, and the optical network hole is reserved in each room on -the -spot to carry out the quick assembly or fusion, on the one hand, the construction is inconvenient, on the other hand, the on -the -spot fusion assembly can lead to the instability of optical performance. UTILITY MODEL CONTENT

[0006] The utility model solves the technical problem to provide a wall -penetrating SC type optical fiber movable connector with certain wall -penetrating bending resistance, convenient to assemble and use.

[0007] In order to solve the above technical problem, the technical scheme of the utility model is: a wall -penetrating SC type optical fiber movable connector, including shell, inner shell, plug core and tail sleeve, the shell is detachably sleeved on the inner shell;It further includes a protective shell, the head end of the protective shell is a lead -through part, and the tail end of the protective shell is a sleeve joint part that can be sleeved on the inner shell;When pre -assembling and wall wiring, the protective shell is sleeved on the inner shell;After wall -penetrating, the protective shell is removed and the shell is sleeved on the inner shell.

[0008] As a preferred technical scheme, the lead -through part is conical.

[0009] Preferably, the protective shell is located between the lead-through portion and the sleeve portion and has a transition protection portion.

[0010] Preferably, the protective shell is a metal shell.

[0011] The present application has at least the following advantages: by changing the pre-assembly form of FTTR whole-house optical fiber, the wall-penetrating SC type optical fiber connector with a protective shell is installed at both ends of the optical fiber, and the optical performance is detected, thereby effectively protecting the quality of the connector while ensuring stable optical performance. When wiring the whole house, it is not necessary to use a quick connector for on-site assembly or to fuse the pre-prepared end fiber. When the on-site user penetrates the wall to each room through the wall-penetrating SC type optical fiber connector, the protective shell can effectively protect the connector. After the wall penetration is completed, the protective shell is removed, and then the SC type shell is assembled for use, which greatly reduces the on-site manual operation time, is convenient and fast, and avoids the problem of unstable optical performance caused by on-site fusion assembly.
