En raison de l'augmentation récente du nombre de dispositifs électroniques montés sur les automobiles, un grand nombre de connecteurs, notamment des connecteurs étamés à faible coût, sont utilisés. De ce fait, la fiabilité de leurs contacts est devenue problématique. De plus, pour les connecteurs soumis à l'usure par fretting provoquée par le cycle thermique et les vibrations, la résistance de contact augmente du fait de l'usure de l'étain et du dépôt d'oxydes, ce qui génère des problèmes de mauvais contact. Cette étude vise à analyser l'évolution de la résistance de contact des connecteurs étamés depuis le début de l'usure par fretting jusqu'à la fin de leur durée de vie du point de vue de la fiabilité pratique, et à observer la trace et les caractéristiques de l'usure par fretting au microscope. Cette étude a révélé que l'usure et l'oxydation des connecteurs étamés commencent immédiatement par l'usure par contact, et donc l'accumulation de poudre d'abrasion sur les zones de contact amène les connecteurs à atteindre rapidement la fin de leur durée de vie utile. Il a notamment été démontré que l'amplitude du fretting a une influence considérable sur la durée de vie d'un connecteur. Il est clair que l'étanchéité à l'air, dite "étanche aux gaz" de l'étain dans une zone de fretting, influence considérablement l'usure du fretting.

Abstract: Due to the recent increase in electronic devices mounted on automobiles, a large number of connectors, especially low-cost tin plated connectors are being used. As a result, their contact reliability has become problematic. Furthermore, for the connectors which are subjected to fretting wear caused by heat cycle and vibrations, the contact resistance increases because of wear of tin and deposition of oxides, which generates problems of poor contact. This study is intended to analyze the change in contact resistance of tin plated connectors from the start of fretting wear to the end of their lifetime from the viewpoint of practical reliability, and to observe the trace and the characteristics of fretting wear microscopically. This study found that wear and oxidation of tin plated connectors start immediately with fretting wear, and thus accumulation of abrasion powder on fretting areas causes connectors to reach to the end of their useful lifetime quickly. Especially, it was demonstrated that amplitude of fretting has a considerable influence on a connector's lifetime. It is made clear that air-tightness, so-called "gas-tight" of tin in a fretting area influences fretting wear considerably.
