They are widely used in communication rooms, local area networks, fiber optic sensors, fiber optic communication systems, fiber optic connection transmission equipment, national defense preparedness, etc. They are suitable for telecommunications networks, computer fiber optic networks and 4G / 5G optical testing equipment.

[0003] However, most of the existing fiber optic conversion connectors are made of transfer sleeves and metal parts. In particular, due to the complex manufacturing process and technical limitations of the transfer sleeves, their precision data is greatly lost during use, resulting in a large area of ​​no signal on the optical fiber and may cause certain damage to the optical fiber equipment.

[0004] Therefore, an integrated optical fiber conversion connector with optical fiber is designed. A ceramic core and a ceramic sleeve are provided on the LC end plastic connection block and the FC metal connection block to connect. A section of optical fiber is embedded in the ceramic core. When installing, the optical fiber connector is directly fixedly connected to the internal ceramic core through the LC end plastic connection block, achieving zero-distance matching transmission.

The inner screw part is inserted into the outer screw part and is fixed to the FC metal connection block by an internal thread rotation. The FC metal connection block has a ceramic sleeve embedding port inside. The ceramic core is embedded in the ceramic sleeve and then slidably connected to the optical fiber connector. A fiber entry hole is provided on the top, and the fiber entry hole is provided with a pre-buried optical fiber. The outer screw part is fixed to the optical fiber communication equipment by a nut rotation.

[0010] Furthermore, the optical fiber conversion connector with integrated optical fiber is characterized in that the optical fiber is pre-buried in the ceramic core, and the ceramic core is embedded in the ceramic sleeve, so that it can fit perfectly when docked with the ceramic sleeve.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Embodiment:

[0021] Please refer to Figures 1 - 3 in

[0022] A fiber-optic integrated fiber-optic conversion connector provided in this embodiment includes an LC-end plastic connection block 101, a ceramic ferrule 1, an FC metal connection block 102, an internal screw-threaded part 103 and an external screw-threaded part 105, as well as a ceramic core 2 and a tailstock 3. Rotate the LC-end plastic connection block 101, and the FC metal connection block 102 is rotationally connected inside through a thread. The two ceramic cores 2 are connected through the tailstock 3 and are communicated with each other through a pre-embedded optical fiber 4 in the middle. There is a card slot on the tailstock 3 and it is connected to the internal screw-threaded part 103 by a staple. The internal screw-threaded part 103 is sleeved into the external screw-threaded part 105, and after being embedded into the ceramic core tailstock 3, it is rotationally connected and fixed to the FC metal connection block 102 through an internal thread. There is a ceramic ferrule insertion port inside the FC metal connection block 102. After the ceramic core 2 is embedded into the ceramic ferrule 1, it is slidably connected to the fiber-optic connector. A fiber-optic inlet hole is opened at the top, and the fiber-optic inlet hole is provided with a pre-embedded optical fiber 4 communicating with it. The external screw-threaded part 105 is rotationally fixed to the fiber-optic communication device through a nut inside.

[0023] Furthermore, the fiber-optic socket 104 is connected to the ceramic ferrule 1, and the fiber-optic socket 104 and the ceramic ferrule 1 are of suitable sizes. During use, first insert the fiber-optic connector into the inner sleeve 6 of the LC-end plastic connection block to connect to the ceramic ferrule 1, and extend from the ceramic ferrule 1 to the inside of the ceramic core 2 for seamless matching.

[0024] Furthermore, the outer diameter of the fixing rod 5 is suitable for the inner diameter of the external screw-threaded part 105. In order to prevent the product from moving during the introduction of the optical signal, a fixing rod 5 is provided on the internal screw-threaded part 103 to fix the external screw-threaded part 105, and then the external screw-threaded part 105 is rotationally tightened on the optical device through a thread to ensure the stable performance of the optical fiber transmission.

[0025] Furthermore, the LC-end plastic connection block 101 is connected to the FC metal connection block 102, and there is a thread inside the LC-end plastic connection block 101. On one side of the LC-end plastic connection block 101 where it is rotated, there is an inner sleeve 6 that matches the introduction of the ceramic ferrule 1 and the fiber-optic connector. On the other side, there is a rotating thread that closely fits the FC metal connection block 102, protecting the whole device and improving the safety performance.

[0026] Furthermore, the integrated fiber optic conversion connector with optical fiber is characterized in that the pre-embedded optical fiber 4 is adopted in the ceramic core 2, and the ceramic core 2 is embedded in the ceramic sleeve 1, and its butt joint can be more perfectly fitted and matched. The optical fiber is pre-embedded in the ceramic core 2. When an optical signal is introduced into the interior, it passes through the pre-embedded optical fiber 4 and is refracted and transmitted into the ceramic sleeve 1 on the other end side. The optical fiber connector is connected to the other side. The optical fiber converges with it through the ceramic sleeve 1, and then the signal is led out through the optical fiber connector to form a seamless butt joint. Its loss is less than 80% of that of the conventional optical fiber adapter connector, greatly improving the signal strength in the entire optical fiber communication field and saving the construction labor and material costs of poor optical fiber signals.

[0027] When using the integrated fiber optic conversion connector with optical fiber of the present invention, first check whether the device is normal. During use, first pass the optical fiber connector through the inner lining sleeve 6 at the bottom of the LC end plastic connection block 101, extend from the inner lining sleeve 6 of the ceramic sleeve to the inside of the ceramic sleeve 1, pass through the ceramic sleeve 1 and extend into the ceramic core 2 to communicate with the pre-embedded optical fiber 4. When the other end ceramic core 2 is connected to the optical device, first push the ceramic core 2 into the optical device, and then rotate the external screw member 105 and tighten it to the optical device by rotating the thread.

[0028] When it is necessary to disassemble the integrated fiber optic conversion connector with optical fiber, first disassemble the nut and bolt of the external screw member 105, take out the device, then separate the FC metal connection block 102 from the LC end plastic connection block 101, and take out the ceramic core 2 from the optical fiber conversion connector.

[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
