Latest Patents

One of Haifeng Zhu's latest patents is a SIM card connector designed to prevent SIM card burnout by detecting the insertion and removal of the SIM card. This innovative connector includes a base, signal spring, detection apparatus, and a controller. The detection apparatus works in conjunction with one side of the SIM card, featuring a fixed contact and a detection spring. This setup allows for the detection of the SIM card's action through the separation or union of the fixed contact and the detection spring. The controller plays a crucial role by disconnecting the power supply of the signal spring before the SIM card is separated, thus preventing damage from momentary electric arcs during insertion or removal.
