US Patent 10439317 Hermetically sealed electrical connector assembly

The interposer can include a substrate and first and second electrical connectors mounted to the substrate. The first electrical connector is configured to mate with a hard disk drive subassembly, and the second electrical connector is configured to mate with a flat flex circuit subassembly. The hard disk drive subassembly includes a hard disk drive case, a printed circuit board, and a third electrical connector mounted to the printed circuit board. The first and third electrical connectors are configured to mate with each other through the hard disk drive case so as to mate the interposer to the hard disk drive subassembly. The hard disk drive case can be hermetically sealed to the substrate of the interposer to prevent gas leakage
