An optical fiber airtight cabin penetration connector

Abstract

The invention discloses an optical fiber airtight cabin crossing connector, comprising a cabin crossing sealing flange and two socket assembling bodies which are arranged inside and outsidethe cabin, and a connection cover plate and a plurality of metalized optical fiber assemblies; the socket assembling bodies are symmetrically arranged on two ends of the cabin crossing sealing flange through the connection plate cover; the metalized optical assembly comprises a nickel tube, a stainless steel pipe and a loose cannula; the optical fiber is sealed inside the nickel tube through a first sealing material; the stainless steel tube is integratedly crimped with the nickel tube by passing through the optical fiber; the loose tube is arranged on the outer ends of the stainless steel and the nickel tube; the stainless steel tube is arranged in the middle of the flange and the connection is sealed through the second sealing material. The invention solves the problem that the sealing effect of the current optical fiber airtight cabin crossing connector is unstable and the sealing rate is low. Furthermore, the insertion core in the invention is in a floating free state, which enables the insertion cone to have a certain adaptive ability during the grounding and can better effectively transmit the signal.

Description

technical field [0001] The invention relates to a connector, in particular to an optical fiber airtight cabin penetration connector. Background technique [0002] Such as figure 1 It is the existing optical fiber airtight cabin penetration connector 100, which mainly adopts the following structure: [0003] Put the outer ferrule 101 into the hole of the fiber sealing seat 102 by press-fitting, insert the optical fiber 103 into the hole of the outer ferrule 101, put glass solder 104 in the central microhole of the fiber sealing seat 102, and heat After melting, fix the optical fiber 103 in the fiber sealing seat 102; put the inner ferrule 105 into the hole of the optical fiber sealing seat 102, and use epoxy glue 106 to bond the two ends of the optical fiber 103 to the inner ferrule 105 and the outer ferrule respectively. In the core 101, the inner ferrule 105 and the outer ferrule 101 are processed into a PC or APC-type butt joint surface, and then fixed in the sealing fla...

AI Technical Summary

Problems solved by technology

[0005] 1. The ferrule is loaded into the optical fiber sealing seat hole by press-fitting, which has the defects of low success rate of press-fitting, unreliable press-fitting and poor anti-vibration ability

[0006] 2. This structure is unreasonable for the process of putting glass solder into the central microhole of the optical fiber sealing seat

[0007] 3. The ferrule is in a relatively fixed state that cannot be floated, and it cannot adapt well to the eccentricity problem caused by the machining error of the parts, which increases the machining accuracy requirements of the parts, thereby increasing the processing cost
