海洋大气模拟环境下电连接器安装防护工艺验证分析

摘要

目的：研究海洋大气模拟环境下，电连接器不同安装防护工艺方法的环境适应性。方法选取有代表性的电连接器，以不同的安装防护工艺装配在典型结构材料制作的安装板上，在实验室加速腐蚀环境下，验证其不同的防护效果。结果电连接器线缆的不同防护工艺将对电连接器基本电性能造成直接影响，安装板与电连接器接触面的防护工艺不同将对其基体材料的腐蚀程度造成很大差异。结论采用热缩管对连接器线缆进行有效的密封能保护电连接器内部结构，避免腐蚀介质的侵蚀对电性能造成影响，电连接器安装（包括方盘安装和气密螺母安装），应对其安装接触面进行填角密封，且安装板前后两面都需要进行密封。%Objective To study the environmental adaptability of different installation and protection technology for electric-al connector in the ocean atmosphere simulation environment.Methods Some representative electrical connectors were selected and assembled to the mounting plate of the typical structure material with different installation protection technology. The dif-ferent protective effect in the laboratory accelerated corrosion environment was tested and verified.Results Different protection technology of electric connector cable would affect the basic electrical properties of electrical connector directly. The different protection technology of the contact surface between the mounting plate and the electric connector would cause a great differ-ence in the degree of corrosion.Conclusion Sealing electrical connector cable with heat shrink tube can protect the internal structure of electrical connector and avoid effect of corrosive medium on electrical properties. In the installation of electrical connector (including installation of square plate and tight nuts), the gap at the edge of the contact surface should be sealed and both the front and rear surfaces of mounting plate should be sealed well.
