Dupa parerea lui nenea asta, ar trebui sa fi abandonat deja de mult acest tip de conector, mi-e greu sa cred ca sunt asa putin rezistente, dar e de notat...
"We highly recommend using only gold terminals for your connectors. Tin plated contacts usually have a life of about 10 cycles (a cycle being plugging in and unplugging) before the contact goes outside of its rated specs (possible specs being contact resistance and holding strength).
Basically, the plating starts to rub off and the contact becomes prone to oxidation, and the contact(s) start to lose their springiness, increasing contact resistance. “Contact resistance” refers to electrical resistance, which can impede power going to the servo and possibly disrupt the servo signal. In most electronics applications the connector would be plugged in once and never touched again, so 10 cycles would be fine, but they're simply not meant for the repeated use seen from hobbyists.
Gold connectors have a life of 50-100 cycles, offer lower contact resistance, and are extremely resistant to corrosion.
These numbers probably still seem low but keep in mind that the contact isn't going to fail after 100 cycles, it will just gradually
increase in contact resistance and decrease in holding strength (the springiness of the contacts is reduced). "
