Study on the Reliability of Plugging and Detaching Fisheye Contact

Abstract

Aiming at contact instability and the deformation problem of possible contact between the fisheye structure and the through hole in the fisheye shaped contact pairs, for pair alignment of fisheye shaped pairs, simulation analysis and experimental research of plug and play is conducted in this paper. Firstly, the important parameters of each structure of fisheye shaped contact pairs are analyzed, then, according to analyze the influence factors of fisheye shaped contact on deformation and insertion force, and based on ABAQUS software to study plug and simulate fisheye shaped contact under different parameters, it is concluded that the insertion force, structural deformation and signal transmission of fisheye shaped contact have great influence on the contact force of fisheye under different material parameters and structural parameters. Multiple plug experiment on fisheye shaped contact pairs was conducted, and the reliability of plug and socket contact insertion has significant influence on plug and play reliability was obtained, thus theoretical basis for the design of fisheye shaped structure, the setting of tolerance range and the control of frequency of use was provided.
