Amass fourth generation smart device special high current connector adopts automotive crown spring structure, through the oblique internal arch elastic contact structure to achieve effective current-carrying connection, compared with the XT series, with three times full contact, effectively prevent the plug off, longer service life, and the same load current, to achieve connector low temperature rise control (temperature rise <30K). At the same load current, the temperature rise is lower, the heat loss is less, and the service life of the connector product is longer.
