Lousy IEC Connections

Something has changed w/ the IEC's imo.  And my guess is that these hundreds of manufacturers have expanded their acceptabe tolerance levels on IEC's so that they do not have to reject the thousands of plugs that they purchase.  It is an easy fix.  Hold the plug manufacturers feet to the fire and have them supply plugs that provide a snug fit.  They all want to yap about how great their wire is and then put a sloppy connector on it.  Follow the money.

Yes, this is an issue, and there are easy fixes for. My greatest issue with pc's is having iec into equipment being at all manner of placement. Grounds may be top, bottom, right or left, often have to twist stiff pc which pulls equipment off specialized footers. As a result, I now only use more pliable pcs.

The Furutech FI-15 Plus IEC connectors actually have a very tight fit when inserted into equipment.  This is both with the plug casing itself (which the fit into the IEC socket is very tight and snug) as well as the strength of the internal contact clamp mechanism.  The more expensive Furutech connectors are still pretty okay, but not quite as tight fitting.

The Neotech IEC connectors are tight fitting as well.

Which reminds me, what a walrus has in common with Tupperware: they both like a tight seal. 

A classic.
These are all good suggestions - cable risers, shrink wrap, friction tape, teflon tape, installing aftermarket connectors, etc. but....these are all patches.  The root cause is not being addressed; and that is ultimately up to the manufacturers.  IMO, for the money that we spend on this stuff we should not be accepting of applying patches.  I doubt that any of us would be accepting of having a new toillet installed and being told as the plumber walked out the door to make sure we jiggled the handle.
