【目的】
2
在构建大型海底工程水下互联项目时,水下湿插拔光电混装连接器是其核心器件,为了打破国外技术和产品垄断,实现自主可控,文章对其关键技术进行了分析并进行了产品研制。
【方法】
2
文章采用等压平衡、旋转密封、充油缆密封连接、多级引导精准对接与到位识别、非接触式光接触件和光纤调芯等关键技术,研制出了水下湿插拔光电混装连接器,并对其进行了高压水下插拔试验、充油缆的振荡飞线和飞线拉力试验以及最大偏移插拔试验。同时,对水下湿插拔连接器的关键静、动密封问题以及动态插拔过程中的接触压力进行了仿真分析。
【结果】
2
高压水下插拔试验结果表明,静水压力为45 MPa时,水下湿插拔连接器的插头和插座在插拔100次后,连接器的插入损耗(0.5 dB)及绝缘电阻(≥50 GΩ)均合格;充油缆锥面密封结构抗拉能力及端接可靠性均能满足要求。仿真分析结果表明,水下湿插拔连接器在动态插拔过程中滚轴的接触压力始终大于水压,能始终保持动密封,不发生泄漏。对于静密封结构,当水压为70 MPa时,不会造成海水泄漏进设备内部,但随着间隙的增大,O形圈变形、所受应力及其与壁面的接触压力均呈增大趋势,对于动密封结构,插针运动速度越快,海水压力越大,其泄漏量也越大,试验验证结果与仿真情况具有较好的一致性。
【结论】

文章所得结果可为水下湿插拔光电混装连接器的设计提供理论指导。
【Objective】
2
In the construction of large-scale underwater interconnection projects for submarine engineering
the underwater wet-mateable hybrid optoelectronic connector is a key component. To break the monopoly of foreign technologies and products and achieve self-reliance and controllability
the paper analyzes its key technologies and develops the product.
【Methods】
2
The paper employs key technologies such as isobaric balance
rotary sealing
oil-filled cable sealing connection
multi-stage guided precise docking and position recognition
non-contact optical contacts
and fiber core adjustment to develop an underwater wet-mateable hybrid optoelectronic connector. The connector is subjected to high-pressure underwater mating and unmating tests
oscillation and tension tests of oil-filled cables
and maximum offset mating and unmating tests. Additionally
the paper conducts simulation analyses on the critical static and dynamic sealing issues of the underwater wet-mateable connector
as well as the contact pressure during dynamic mating and unmating processes.
【Results】
2
The test results show that the insertion loss (0.5 dB) and insulation resistance (≥50 GΩ) of the connector are qualified after 100 times of plugging and unplugging under the pressure of 45 MPa. Tensile capacity and end connection reliability of oil-filled cable cone sealing structure meet the requirements. The simulation analysis results indicate that during the dynamic mating and unmating process of the underwater wet-mateable connector
the contact pressure of the rolling shaft is always greater than the water pressure
ensuring dynamic sealing and preventing leakage. For static sealing structures
when the water pressure is 70 MPa
there will be no seawater leakage into the equipment interior. However
as the gap increases
the deformation
stress
and contact pressure of the Oring with the wall surface all show an increasing trend. For dynamic sealing structures
the faster the pin movement speed
the greater the seawater pressure
and the greater the leakage amount.
【Conclusion】
2
The obtained results in the paper can provide theoretical guidance for the design of underwater wet plugin optoelectronic hybrid connectors.
