Description

Technical Field

[0001] This utility model relates to the field of single-core optical fiber splicing technology, and in particular to a structure for a fast splicer for single-core optical fiber cables used in communication. Background Technology

[0002] A single-core fiber optic cable quick connector for communication is a device used to connect two single-core optical fibers. Its main function is to precisely align the end faces of the two fibers to ensure maximum coupling of optical signals while minimizing the impact on the optical link system. Fiber optic connectors can be classified into various types according to their connector structure, such as FC, SC, ST, and LC. Each type has its specific application scenarios: FC type is suitable for applications requiring high reliability and long-term stability; SC type is inexpensive and easy to plug and unplug, suitable for high-density fiber optic connections; ST type is typically used at the cabling equipment end, such as fiber optic distribution frames; and LC type is small in size and suitable for high-density fiber optic connection environments.

[0003] Existing devices, such as CN218995726U, disclose an FTTH fiber optic connector. The connector has a mating groove on its base for splicing optical fibers, and sliding grooves are respectively formed axially on both sides of the mating groove. The sliding cover includes a first sliding cover and a second sliding cover, wherein the first and second sliding covers are horizontally inserted into the sliding grooves on the base via first and second dovetail ribs, respectively. A first variable diameter limiting groove and a second variable diameter limiting groove are respectively formed in the first and second sliding covers to clamp and position the splicing optical fibers within the mating groove. In this application, by installing and horizontally inserting sliding covers on the fiber optic connector base, the first and second sliding covers are used to position the optical fibers axially and vertically; thereby reducing the use of threaded connectors, facilitating flexible installation, and improving the efficiency of fiber optic connection installation.

[0004] When workers need to connect optical fibers, they place one end of two optical fibers in the connector structure so that the connector structure can connect the two optical fibers together to achieve communication. However, during use, the connector structure may have large gaps, which allow dust to enter the interior of the connector structure and come into contact with the optical fiber ports, thus reducing the communication quality of the optical fiber.

[0026] Specifically, a rubber block 32 is fixedly connected to the inner side of the sealing cap 31. The rubber block 32 is inserted into the interior of the air inlet 33. The rubber block 32 can cooperate with the sealing cap 31 to achieve the purpose of sealing the air inlet 33.

[0027] Specifically, the surface of the second connecting cover 2 is provided with a fastening device 4, which includes a pull bar 44, and the pull bar 44 is slidably connected to the inner side of the second connecting cover 2.

[0028] In this embodiment: the pull strip 44 is located below the first connecting cover 1.

[0029] In this embodiment, the pull strip 44 can cooperate with the first connecting cover 1 to guide the pull strip 44 to slide.

[0030] Specifically, one end of the pull bar 44 is fixedly connected to a limiting sleeve 45, which is fitted onto one end of the first connecting cover 1 and the second connecting cover 2.

[0036] Working Principle: By setting up the sealing device 3, when the operator needs to seal the connector structure, the operator places the two ends of the two optical fibers on the receiving plate 39 respectively, presses the optical fibers, and the optical fibers push the receiving plate 39 open. The receiving plate 39 drives the clamping plate 37 to expand its inner diameter, and the optical fibers are inserted into the inner diameter of the clamping plate 37. The clamping plate 37 resets and clamps the optical fibers, and the two optical fibers abut against each other. The operator connects the air pump to the air inlet 33, and the air pump injects air into the inner side of the metal ring 34 and the cavity 36 of the air bag 35. The air bag 35 expands, and the inner diameter of the air bag 35 gradually shrinks, so that the air bag 35 is in close contact with the surface of the optical fiber. The side of the air bag 35 is in close contact with the first connecting cover 1 and the second connecting cover 2. By setting up the sealing device 3, the gap between the connector structure and the optical fiber can be effectively sealed, preventing dust from entering the interior of the connector structure from the gap, thereby improving the communication quality of the optical fiber and making it easier for the operator to align the optical fiber. In addition, by setting up the fastening device 4, when the operator needs to quickly install the fastening device, the operator can quickly install the fastening device 4. When installing the connector structure, the worker installs the optical fiber inside the second connecting cover 2, and places the first connecting cover 1 on the second connecting cover 2. The anti-slip block 47 on the lower surface of the first connecting cover 1 is inserted into the interior of the second connecting cover 2, pushing the limiting sleeve 45. The limiting sleeve 45 pushes the pull bar 44, which is guided by the second connecting cover 2. The limiting sleeve 45 drives the limiting ring 41, which drives the threaded ring 42 to abut against the surfaces of the first connecting cover 1 and the second connecting cover 2. The metal ring 34 is rotated, which drives the threaded ring 42. The threaded ring 42 is threadedly connected to the surfaces of the first connecting cover 1 and the second connecting cover 2. When the threaded ring 42 abuts against the abutment ring 43, one side of the air bag 35 abuts against the surfaces of the first connecting cover 1 and the second connecting cover 2, stopping the rotation of the metal ring 34. By setting the fastening device 4, the worker can effectively and quickly install the connector structure, avoiding the need to use a large number of bolts when installing the connector structure, thereby improving the worker's work efficiency.
