IP 66 rated electronic enclosure
Ordinary USB and Ethernet connectors are not IP66 rated.
There are many IP67 and IP68 USB and Ethernet connectors around but I couldn't find one IP66 rated.

Reliable manufacturers of IP66/IP67/IP68 rated USB and Etehernet connectors are, among many others: Molex, TE, Bulgin, Amphenol
