Embodiment 1

[0029] see Figures 1 to 7 , in the embodiment of the present invention, a multi-channel optical fiber rotary connector resistant to harsh environments, including a transmission assembly, a Dove prism 5 and a prism sleeve 6, the eight vertices of the Dove prism 5 are set as the glue dispensing place 51. After the dispensing operation is performed at the dispensing position 51, the Dowell prism 5 is glued inside the prism sleeve 6, and the prism sleeve 6 is installed inside the transmission assembly through the fastening bolt 4, and the prism sleeve 6 is installed. It is glued and reinforced with the transmission assembly, so as to complete the installation of the Dowell prism 5 and improve the vibration and shock resistance of the multi-channel optical fiber rotary connector. The group of optical fiber collimators 10 are respectively connected with a rotating end output fiber 11 and a fixed end output fiber 12, wherein the rotating end output fiber 11 is installed on the left ...

Embodiment 2

[0034] see Figures 1 to 8 , the main structure of this embodiment is the same as that of the first embodiment, the difference is: considering that the device needs to work in a harsh environment, it is often necessary to isolate the device and the exchange of external air, which greatly reduces the heat dissipation effect of the device, and Sometimes the device needs to work in a special gas atmosphere. For this reason, two inflatable nozzles 13 are symmetrically installed in the side wall of the fixed end outlet end cover 8. In the side wall, the setting of double air nozzles is adopted. On the one hand, one air nozzle can be inflated, and the other air nozzle can be sealed, and some kind of gas, such as dry air, can be filled in the multi-channel optical fiber rotary connector. After ensuring a certain pressure, the air nozzle can be sealed. , which can reduce the risk of internal condensation. On the other hand, one can be used as an air inlet nozzle and the other can be u...

Abstract

The invention discloses a multi-path optical fiber rotary connector resistant to a severe environment, and relates to the technical field of optical signal rotary transmission. The multi-path optical fiber rotary connector comprises a transmission assembly, a Dove prism and a prism sleeve. The gap between the Dove prism and the prism sleeve is controlled in a reasonable range, and the Dove prism is fixed in the prism sleeve through dispensing. The prism sleeve is fastened through a fastening screw and then sealed with glue, so that the vibration impact resistance of the multi-path optical fiber rotary connector is improved. Meanwhile, optical fiber collimators are installed at the two ends of the transmission assembly through optical fiber collimator fixing end covers, and each path of optical fiber collimator corresponds to one optical fiber collimator fixing end cover. A split type optical fiber collimator fixing end cover structure is adopted, the fixing end cover of each optical fiber collimator can be independently adjusted, so that the filling gap of sealing glue can be reduced, the index change caused by the deformation of the glue during the high and low temperature change can be controlled, and the high and low temperature performance of the multi-path optical fiber rotary connector can be improved. Suitable gas can be introduced into the multi-path optical fiber rotary connector through external equipment by designing a charging connector.

Description

technical field [0001] The invention relates to the technical field of optical signal rotation transmission, in particular to a multi-channel optical fiber rotary connector resistant to harsh environments. Background technique [0002] The multi-channel optical fiber rotary connector can realize the 360° rotating transmission of optical signals from the fixed part to the rotating part. Patents 02279871.4 and ZL201020253642.X disclose the realization method of the multi-channel optical fiber rotary connector, but do not explain how to ensure the multi-channel optical fiber. The environmental adaptability of the rotary connector cannot meet the use requirements of some harsh environments. The patent ZL201520330179.7 provides a method of attaching a heating plate, but it does not fundamentally solve the problem of its own environmental adaptability of the multi-channel optical fiber rotary connector. . With the rapid development of optical fiber communication technology, the a...
