Description

technical field [0001] The invention relates to the technical field of communication, in particular to a photoelectric hybrid airtight through-cabin socket. Background technique [0002] The airtight cabin penetrating socket is a key component to solve the application of signal transmission technology in the space environment. Harsh environmental influences. With the construction of the space station and the continuous upgrading of the space integrated radar system, the transmission of space pictures and video information makes the data volume and processing speed of the system more and more demanding. The traditional high-speed electrical connector signal transmission technology can no longer meet the requirements. It is imperative for optical fiber communication technology to enter the space application system. In addition, electronic equipment for space gradually proposes requirements for miniaturization, integration, and modularization. Simultaneous transmission of opt...

Problems solved by technology

However, the optical fiber cannot use glass sintering technology due to its low working temperature. At present, the optical path sealing mainly adopts the metallization of the optical fiber, and the alloy welding sealing method is used between the shell and the shell. Compared with the traditional epoxy glue seal and O-ring seal, this method has more advantages. It has the characteristics of reliable sealing and strong temperature shock resistance, but it has the disadvantages that the optical fiber contact piece is too long in size, unable to realize simultaneous plugging and unplugging of electrical and optical fiber contact pieces, metallization of bare optical fiber, and easy damage to optical fiber by welding

In recent years, there is also a method of welding and sealing the glass light guide rod with the shell alloy after metallization. This method can solve the shortcomings of the welding and sealing method of the bare optical fiber, but its transmission optical path is "optical fiber-collimating lens-light guide rod-focusing lens ——optical fiber”, there are 4 non-contact spatial couplings in total, the coupling efficiency is low, and the insertion loss of the airtight socket is large
