The Molex 1050570001 is a standard USB 2.0 Type-A receptacle, 4-position, vertical orientation, designed for through-hole soldering to a PCB. It is the receptacle half of the ubiquitous USB-A interconnect — the rectangular port found on host devices, hubs, and chargers. Gold-plated contacts handle thousands of insertions before wear-through.
Board layout and assembly notes
Vertical through-hole mounting: the four signal pins and two shell ground tabs (the shield legs) pass through the PCB. The board lock feature provides a mechanical interference fit that holds the connector in place during soldering — no secondary fixture needed. The shell ground tabs should connect to the board's ground plane for best EMI performance.
