USB-B Receptacle for Panel-Mount and Board-Edge Applications
The TE Connectivity 5788336-1 is a USB 2.0 Type-B receptacle, 4 contacts, rated 1A per contact at 30VAC. It mounts vertically through the PCB with solder termination and includes integrated board locks that anchor the part during wave soldering and resist shear from cable insertion and removal. The phosphor bronze shell provides the grounding and shielding path called out in the USB 2.0 specification, while the contact finish is spec'd as gold or gold-palladium — the gold-palladium option adds wear resistance for applications that see frequent connect-disconnect cycles.
Board Lock and Mechanical Retention
The board lock feature serves two purposes: it holds the connector in place during the solder process so the contacts stay aligned through the plated through-holes, and it adds mechanical resistance to the shear force a USB cable applies when the plug is inserted or yanked at an angle. For a vertical-mount USB-B that sees daily field mating — think industrial panel interfaces, test equipment front panels, or kiosk ports — those board locks are what keep the solder joints from cracking over the connector's 1500-cycle rated life.
