doi:10.12068/j.issn.1005-3026.2018.01.015

Abstract

Abstract: The contact calculation model for the cylindrical double groove electric connector， a significant component in aerospace equipment， was established. The mathematical relationship between the contact friction force and the insertion amount of pins was derived. The parameterized modeling for 38999 series 22^# general contact elements was performed using SOLIDWORKS， and the contact performance was analyzed using ABAQUS finite element analysis software. It is obtained that the optimum closing amount of the socket end， with the insertion force as an assessment index， is 0.66mm. Sensitivity of the socket structure parameters was analyzed， and its structural optimization was determined based on the fuzzy comprehensive evaluation method. The optimum contact performance is obtained when the length of the socket reed is 3mm， the width of the socket slot is 0.43mm and the closing amount of the socket end is 0.67mm.

Key words: electrical connector, contact performance, simulation, insertion force, sensitivity
