Abstract

The invention relates to a design method for an underwater wet type sealing ring for an electrical general connecting head. The design method is used for guaranteeing that the designed and manufactured sealing ring for the electrical general connecting head meets design needs. The design method comprises the following steps of: S1, determining parameters of the underwater wet type electrical general connecting head according to design requirements; S2, performing sealing ring insertion and extraction time test; S3, performing sealing ring temperature ageing test; S4, performing sealing ring abrasion test; and S5, determining final parameters of the underwater wet type electrical general connecting head, and producing and manufacturing based on the final parameters. The design method can beused for performing quantitative analysis on sealing ring insertion and extraction times, sealing ring temperature ageing and sealing ring abrasion, so that the analyzed results are more accurate, and the conclusion is clearer, and therefore, quality of practical products is favorably improved and guaranteed.

Description

technical field [0001] The invention relates to the technical field of wet-plug electrical universal connectors, in particular to a design method for a sealing ring of an underwater wet-type electrical universal connector. Background technique [0002] The underwater wet plug connector is an underwater pluggable connection device exposed to harsh external environments, such as seawater, oil, drilling fluid, etc., for connecting cables and underwater electrical equipment. Underwater electrical equipment provides key components for stable and reliable power and signal transmission. [0003] During the wet plugging and unplugging process of the connector in water, the plug and the socket are filled with seawater. It is necessary to study the working principle of underwater plugging and the dynamic sealing structure to ensure that the contact parts are reliably insulated, and the seawater can be discharged as much as possible. After installation, the contact parts are automatic...
