The Molex 0670680000 is a USB-B (USB TYPE-B) receptacle from the 67068 series, a single-port, 4-contact connector designed for standard USB 2.0 data and power interconnect. It is the board-side half that mates with a USB-B plug from a peripheral cable — think printers, scanners, external drives, or instrumentation where the square B-style port is the device-side interface. The board lock anchors the part through wave solder, taking the mechanical shear from cable insertion and removal off the solder joints. Rated 1.5 A per contact at 30 V, the power pins handle the standard 5 V USB bus current with headroom for charging profiles that stay under 1.5 A. The 1500 mating cycles are well above the 500-cycle baseline for a basic USB port — this receptacle is specced for equipment that sees repeated connect-disconnect over its service life, like a test fixture or a lab instrument that gets re-cabled weekly.
During wave solder, the tabs hold the connector square to the board. The shielded shell is a copper-alloy can that wraps the four contacts. It mates with the plug's shield before the signal pins engage, providing a low-impedance path to the board's ground pour.
