High quality "locking" IEC connectors?


Does anyone know of a high quality IEC connector (pure copper conductors w/plating) that actually locks into place? Something similar to the connection for a balanced interconnect? or maybe something like a twist lock connection? I'm sick of trying to prop up my power cords to ensure that they are connected securely. I've seen some lower quality connectors available but nothing with good quality copper conductors. This seems like such an obvious need in high end audio. Anybody have any ideas?

No locking types I am aware of. Get a tight fitting connector. Wattgate is another one to consider.
Thanks for responding you guys. It amazes me sometimes how much time/money/effort is spent tweaking/designing audio stuff to reach "state of the art" reproduction and then simple/no brainer/obvious stuff doesn't get addressed. The balanced IC's snap in, why not the PC's!
There are some solutions out there. Unfortunately most require some modifications.

Hey thanks Ncarv.

I saw another set up like these. Unfortunately, the conductors are not the quality that I am looking for. But these have given me some ideas! I'm going to fabricate something that will go over the outside of the connectors and couple them tightly together. Stay tuned.

Thanks for responding.

IeGO makes an IEC receptacle that has a support. You can find it on the CryoParts list. I haven't listen to the the IeGO connectors, but they've been building a good reputation and they're base is either pure silver or Furukawa copper.
