However, the following embodiments are only the preferred embodiments of the present utility model, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all fall within the protection scope of the present utility model.

[0024] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment 1:

[0026] Refer to Figures 1-4, A low return loss optical connector, comprising a first housing 1 and a second housing 2. The outer wall of the first housing 1 is provided with a second anti-slip piece 9. The inside of the second housing 2 is provided with an optical fiber body 10, and the optical fiber body 10 is positioned and connected to the second housing 2. The inside of the second housing 2 is provided with four limiting protrusions 13, and the four limiting protrusions are arranged in a matrix. The limiting protrusions 13 are welded to the second housing 2. One side of the first housing 1 is provided with a threaded interface 6, and the threaded interface 6 is positioned and connected to the first housing 1. One side of the first housing 1 is provided with an optical fiber line 11. The inner wall of the first housing 1 is provided with a limiting body 15. The inside of the limiting body 15 is provided with an optical fiber receiving groove 14, and the optical fiber receiving groove 14 is the same length as the limiting body 15. The top of the limiting body 15 is treated with a rounded corner. The inside of the limiting body 15 is provided with six ventilation channels 5, and the six ventilation channels 5 have the same diameter and the same depth. One side of the limiting body 15 is provided with a limiting groove 7. The inside of the first housing 1 is provided with an inflation pipeline 4. One side of the inflation pipeline 4 is provided with a rubber plug 8, and the rubber plug 8 is fitted with the inflation pipeline 4. The top of the rubber plug 8 is treated with a rounded corner. The outer wall of the second housing 2 is provided with a first anti-slip piece 3. One side of the second housing 2 is provided with a threaded joint 12. In this way, when in use, four limiting grooves can be provided on the outer wall of the limiting body, and limiting protrusions are provided inside the second housing. At the same time, ventilation channels are provided inside the limiting body. When in use, the optical fiber body is connected to the optical fiber receiving groove, and the internal air at this time will enter the ventilation channels, and the gas is released outside the ventilation channels. At the same time, the released gas can blow away the floating dust on the optical fiber body. Therefore, blowing away the floating dust can reduce the influence of impurities on the optical fiber connection surface and improve the quality of the optical fiber connection. At the same time, by providing four limiting grooves on the outer wall of the limiting body and cooperating with the limiting protrusions inside the second housing, accurate and stable limiting can be achieved, reducing the risk of signal loss and connection failure caused by connection looseness or offset. An inflation pipeline penetrating the first housing is provided on one side of the first housing, and a rubber plug is provided at the top of the inflation pipeline, realizing that when in use, the optical fiber receiving groove can be inflated with inert gas through the inflation pipeline. After inflation, the loss of the optical fiber is reduced. Filling the optical fiber receiving groove with inert gas can reduce the reflection and scattering of light during transmission, thereby significantly reducing the return loss and improving the transmission quality and efficiency of the optical signal. At the same time, the inert gas has a stable chemical property and is not easy to chemically react with the optical fiber or the materials inside the connector. The inert gas is nitrogen, and at the same time it has a stable chemical property, which can effectively prevent the optical fiber from oxidizing and being affected by moisture and reduce the chemical reaction on the surface of the optical fiber. Specific Embodiment Two:

[0028] Refer to Figures 1-4, an electromagnetic shielding cover is added to one side of the first housing 1 and the second housing 2, so that when in use, it can effectively block the interference of external electromagnetic fields on the optical signal transmission inside the connector, ensure the stable and accurate transmission of optical signals, reduce the transmission error rate, and thus also help to maintain the quality and integrity of optical signals and reduce signal distortion and attenuation caused by electromagnetic noise.

[0029] In summary:

[0030] 1. Four limiting grooves are provided on the outer wall of the limiting body, and a limiting protrusion is provided inside the second housing. At the same time, an air vent passage is provided inside the limiting body. When in use, the optical fiber body is connected to the optical fiber connection slot, and the internal air will enter the air vent passage at this time, and the gas is released outside the air vent passage. At the same time, the released gas can blow away the floating dust on the optical fiber body. Therefore, blowing away the floating dust can reduce the influence of impurities on the optical fiber connection surface, improve the quality of the optical fiber connection. At the same time, by providing four limiting grooves on the outer wall of the limiting body and cooperating with the limiting protrusion inside the second housing, accurate and stable limiting can be achieved, reducing the risk of signal loss and connection failure caused by connection looseness or deviation.

[0031] 2. An inflation pipeline penetrating the first housing is provided on one side of the first housing, and a rubber plug is provided at the top of the inflation pipeline. When in use, it is possible to inflate the optical fiber connection slot with inert gas through the inflation pipeline. After inflation, the loss of the optical fiber is reduced. Filling the optical fiber connection slot with inert gas can reduce the reflection and scattering of light during transmission, thereby significantly reducing the return loss and improving the transmission quality and efficiency of optical signals. At the same time, the inert gas has stable chemical properties and is not easy to chemically react with the optical fiber or the materials inside the connector.
