Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to an optical fiber connector. Background Art

[0002] Fiber optic connectors are devices that make detachable (movable) connections between optical fibers. They precisely connect the two end faces of optical fibers so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] Patent announcement number CN220961932U discloses a connection for optical fiber communication. The patent comprises a connector body, a conductor, a sleeve, a protective cover, a connection block, a cathode magnet block, an anode magnet block and a sealing ring. During use, the connector body is plugged into a device to be connected, and then the movable protective cover is fitted with the connected device. With the cooperation of the cathode magnet block and the anode magnet block, the protective cover can be limited to prevent it from moving. The sealing ring can further improve the sealing effect of the protective cover, thereby preventing dust from entering the gap between the connector and the connected device, thereby ensuring the normal use of the connector body. However, the connection method between the device and the optical cable is not conducive to disassembly and assembly. When there is a problem with the connector body or the optical cable, maintenance and replacement are more troublesome.

[0004] Based on this, a fiber optic connector is now provided to eliminate the drawbacks of the existing devices. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] In one embodiment, Figure 1-Figure 4 As shown, a fiber optic connector includes a housing 100, one end of the housing 100 is provided with a ceramic ferrule 200, and the other end of the housing 100 is provided with a flip mechanism 300. Through the above arrangement, the device connects the optical fiber to the machine through the ceramic ferrule 200, and the flip mechanism 300 can facilitate the disassembly and assembly of the optical fiber.

[0026] In one embodiment, Figure 3 As shown, the flip mechanism 300 includes a lower fixed shell 301, which is fixedly connected to the shell body 100, and one end of the lower fixed shell 301 is fixedly provided with two rotating shafts 303. The lower fixed shell 301 is rotatably connected to the upper flip shell 302 through the rotating shafts 303. A locking structure 400 is also provided on the lower fixed shell 301. Through the above arrangement, the upper flip shell 302 can rotate on the lower fixed shell 301 through the rotating shafts 303.

[0027] In one embodiment, Figure 3 As shown, the locking structure 400 includes a conical locking block 401 and a fiber clamping block 403. The conical locking block 401 is arranged on both sides of the lower fixed shell 301 away from one end of the rotating shaft 303. A clamping groove 402 is provided on the upper flip shell 302 at a position opposite to the conical locking block 401. The fiber clamping block 403 is arranged in the lower fixed shell 301 and the upper flip shell 302. Through the above arrangement, when the lower fixed shell 301 and the upper flip shell 302 are closed, the fiber clamping block 403 will clamp the optical fiber, and the conical locking block 401 will cooperate with the clamping groove 402 to lock it.

[0028] In one embodiment, Figure 3 As shown, the optical fiber block 403 includes a lower block 404 and an upper block 405. The lower block 404 is arranged in the lower fixed shell 301, and the upper block 405 is arranged in the upper flip shell 302. Through the above arrangement, when the upper flip shell 302 is closed, the upper block 405 and the lower block 404 will be driven to close.

[0029] In one embodiment, Figure 4 As shown, the optical fiber card block 403 array is provided with four, and through the above arrangement, the optical fiber card block 403 can lock the optical fiber more tightly.

[0030] Example 2

[0031] In one embodiment, Figure 1-Figure 2 As shown, a dust cover 600 is disposed on the outer side of the shell 100. Through the above arrangement, the dust cover 600 can absorb a large amount of dust around the connector to prevent the dust from floating into the connector.

[0032] In one embodiment, Figure 4 As shown, one end of the pre-buried optical fiber 500 extending into the housing 100 is coated with optical fiber matching paste. Through the above arrangement, the connection accuracy between the external optical fiber and the pre-buried optical fiber 500 is improved, and the working efficiency of the optical fiber is improved.

[0033] The above embodiment discloses an optical fiber connector, which is provided with a flip mechanism 300 for placing optical fibers. When the flip mechanism 300 is closed, the lower clamping block 404 and the upper clamping block 405 arranged inside the flip mechanism 300 will work together to lock the optical fiber, and the conical locking blocks 401 arranged on both sides of the lower fixed shell 301 will cooperate with the clamping grooves 402 opened on both sides of the upper flip shell 302 to lock the flip mechanism 300. When the optical fiber needs to be replaced, the lower fixed shell 301 is squeezed to unlock the conical locking block 401 and the upper flip shell 302 to open the flip mechanism 300. At the same time, the dust cover 600 arranged outside the shell 100 can effectively absorb dust to prevent dust from affecting the working ability of the optical fiber.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
