Porturile Lightning, impreuna cu cablurile aferente, au fost introduse de catre Apple in iDevice-urile sale in anul 2012, cand iPhone 5 a fost prezentat oficial. Ele si-au facut apoi loc in iPad 4 si iPad Mini, iar anul acesta toate iDevice-urile lansate de catre compania americana au implementat acest standard. Desi compania Apple a prezentat standardul Lightning ca o evolutie a tehnologiilor sale, se pare ca el are totusi o problema destul de mare, fiind afectat de coroziune.
About a month ago the Apple Lightning to USB cable (PN: MD818ZM/A, $19) that I keep in my vehicle for charging my iPhone 5s began to fail. At first charging was intermittent, then within a week the cable wouldn’t charge my iPhone at all. A closer look at the male end of the Apple Lightning to USB cable reveals that several of the gold contacts have become corroded.
Dupa cum puteti vedea deja din imaginile acestui articol, unele cabluri Lightning sunt afectate de coroziune care apare in dreptul contactelor aurii, iDevice-urile nemaifiind incarcate sau recunoscute de catre calculatoare. Problema nu este chiar atat de izolata, deoarece pe forumurile de discutii ale Apple exista destule persoane
care au intampinat aceasta problema chiar si la cateva luni de la lansarea acestor cabluri, expunerea la zone cu umiditate ridicata generand corodarea cablurilor.
- two gold electrodes placed in an aqueous solution with a positive voltage on one wire and ground applied to the other will corrode the positive gold electrode away
- electrical arcing causing the corrosion (originally I dismissed this as it is just USB – i.e. 5 V /2 A max)
- After examining the male and female sides, it would seem both are likely culprits, but you would have to have some pretty serious condensation on the pins to get this to happen with steam.
Oferind o posibila explicatie pentru problema un utilizator sustine ca utilizarea cablurilor in zone in care exista umiditate extrem de ridicata sau udarea contactelor si utilizarea pentr incarcare va genera aceasta corodare, insa nu in toate cazurile. Pana acum compania Apple nu a oferit vreo explicatie pentru problema, asa ca ar fi bine sa fiti atenti cu aceste cabluri.
