Standard USB-A Port for Board-Edge Mounting
The Molex 676432910 is a USB Type-A receptacle from the 67643 series, designed as a standard downstream port for host-side or hub-side connections. It carries 4 contacts — the standard USB 2.0 pinout for power (VBUS, GND) and a differential data pair (D+, D-). Rated at 1.5A and 30VDC, this connector has gold-plated contacts and a shielded shell of copper alloy.
Mounting and Retention on the Board
This is a through-hole, right-angle mount with integrated board locks — the two large-diameter solder posts on the shell legs anchor the connector to the PCB and take the mechanical strain of cable insertion and removal. The board locks also provide a low-impedance ground path from the shield to the board ground plane, which helps keep the USB signal return clean. The shielded shell is made from copper alloy, and the shield is soldered to the board through the same through-hole posts. For designs that need to pass radiated emissions testing, the shield-to-ground connection is critical — the board lock posts carry that current before it reaches the signal pins.
