In this paper, the mechanical constitutive model of fuzz button connector was studied from a theoretical perspective. Based on the structure of the fuzz button, the spatial configuration and contact mode of the metallic protofilament were analyzed, and the meso structural unit of the single metallic broken-line segment based on the simply supported beam structure was proposed. From meso to the unit structure, the constitutive model of the fuzz button connector subjected to a certain compressive load was derived. Some basic parameters such as the diameter and the elastic modulus of the metallic protofilament, relative density of the fuzz button, the length and winding angle of broken-line segment, which were all included in the model. It fills the blank of the mechanical research of the fuzz button connector, and provides a theoretical basis for further research on the mechanical characteristics of the fuzz button connector and guiding the practical application.
