USB-B Receptacle, 4 Contacts, Obsolete — Sourcing Note
The TE Connectivity 787780-1 is a USB-B (USB TYPE-B) receptacle, the standard rectangular female port found on peripheral devices like printers, hubs, and instruments. It carries 4 contacts in a single row, rated 1A per contact at 30VAC — the typical power and signal envelope for USB 2.0 and USB 1.1 interfaces.
Board Lock and Mounting Detail
After soldering, they provide mechanical retention that resists the push-pull forces from the USB cable, reducing stress on the signal pins. This is a practical detail for any board that sees repeated cable connections.
