Spring loaded ground contact: retractable element with separate wedge contacts which keeps the shell in the front position when engaged thus also providing a direct and strictly coaxial electrical connection from the socket via the shell to the cable shield.

All metal design, machined brass, black coated shell. Easy assembly and soldering (large soldering area, rapid-flow plating). High grade plastic insulator with high creep resistance.
