Sagging power cable at IEC outlet - any remedies?

My power amp has its IEC outlet going into the back flat, and every cord I have tried including the light stock cord sag from the cords weight behind the amp. So in all likelihood the connection isn't as strong as it should be. I know connection strength matters at the other end of the cord going in to the wall outlet, is it the same here?

For others suffering from this problem have you found a way to prevent the cord sagging out?

How about a 5 foot power cord that weighs less than 1 pound, and a strong gripping IEC?

How about coming up with "locking IEC's" ? Like balanced XLR's ? Closer tolerances ?

I've tested several batches of Schurter and Wattgate IEC320s. The Wattgates have an average separation force of 16 pounds; the Schurter only 4 lbs. I use the Schurter for lighter-weight PCs for source components, but the WattGates for heavier PCs for amps, etc., or as an upgrade. Ern

Get rid of the connector. Power cords should be hard soldered, to the transformer primary unless there is a power switch.

By the way, a little sag might actually improve contact. Isn't that what we do with a lamp plug when it doesn't work?

Electrical tape works, but 3/4" heat shrink sold at most hardware store is better and cleaner. Depending on the
gap between the plug and IEC outlet, a second layer might be needed.
