Problems solved by technology
[0002] At present, the common way to use optical fiber connection is to use a special joint to connect two optical fibers together. However, if one optical fiber is damaged by pressure fluid, the pressure fluid will damage the other optical fiber through the joint, and the joint cannot isolate the pressure; Thus destroying more expensive spectroscopic instruments

The invention discloses a fiber connection seal and pressure bearing joint comprising a pressure bearing housing; the pressure bearing housing is split by a multi-core fiber pressure bearing joint body to form a left cavity and a right cavity; a spectrum apparatus and a reception fiber are arranged in the left cavity; the spectrum apparatus is connected with a fiber joint of the multi-core fiber pressure bearing joint body via the reception fiber; a transmission fiber and a sapphire window are arranged in the right cavity; one end of the transmission fiber is connected with the sapphire window, and the other end is connected with the fiber joint of the multi-core fiber pressure bearing joint body. The fiber connection joint is based on a collimating mirror and formed by the sapphire glassand a sealed ring; an optical signal of one fiber is transmitted to the other fiber via the collimating mirror and the sapphire glass; if one fiber is damaged by pressure, the sapphire glass and the sealed ring can stop a pressure liquid from passing and damaging the other fiber, thus protecting the expensive spectrum apparatus.
Description
technical field [0001] The invention relates to the field of petroleum downhole tools, in particular to an optical fiber connection sealed pressure-bearing joint. Background technique [0002] At present, the common way to use optical fiber connection is to use a special joint to connect two optical fibers together. However, if one optical fiber is damaged by pressure fluid, the pressure fluid will damage the other optical fiber through the joint, and the joint cannot isolate the pressure; Thus destroying more expensive spectroscopic instruments. Contents of the invention [0003] The invention provides an optical fiber connection sealed pressure-bearing joint capable of preventing an external high-pressure fluid from affecting the other end after one end of the optical fiber joint fails. [0004] In one embodiment of the present invention, a sealed pressure-bearing joint for optical fiber connection is provided, which includes a pressure-bearing shell, and the inside of ...
