Heavy Power Cords

The IEC connector is one of the worst form of electrical plug and receptacle devices ever made.

OT: I vote for the 1/8" stereo mini-plug and jack. Followed closely by the 1/4" headphone plug and jack. Neither can be counted on to maintain contact in the event of the slightest jiggling, or after repeated re-insertions. But yes, the IEC is not too far behind. :)

Easy,

Take a piece of black teflon heatshrink tubing (1/2" O.D. ?) carefully cut or trim it to the appropriate length with scissors or a razor blade and stretch it over the end of the power cord's IEC.

Some lube that dries will help slip it on easier.

I cut up cheap 7/16" thick foam work shop floor tiles and stack them horizontally for strong support under all my cables and especially the P/C's where they attach to the equipment.

Sort of like the other mention of it... I'd add some layers of heat shrink, one at a time until the fitting was snug.

Of course, that's not helping the contacts get tighter but will help the cords from pulling loose.... also, I use plain old string to trace up the heavier cords to the rack itself... thereby taking the strain off the connection.

Blindjim suggestion is similar to my own, I use Tiewraps to hold the AC cable in place so there is no strain on the connector.

Likely the same results as he gets with string.
