The 031-70466: It's a crimp-terminated, bayonet-lock connector built for the 75 Ohm video and data coax world — not the 50 Ohm RF bench.
This plug is built for Times Fiber 210 cable — the cable group is specified in the part definition. The shield termination is crimped over the cable braid, and the centre contact crimps onto the conductor. The nickel-plated brass body and gold-plated centre contact handle the 500 mating cycles without the plating wearing through on the signal path. The PTFE dielectric holds the centre conductor concentric, which is what keeps the 75 Ohm impedance consistent through the crimp zone.
