       | TL;DR: Berg made connectors like these. Berg was bought by DuPont
       | who put their branding on things. Around this time in the early
       | 90's, clones started showing up and enthusiasts assigned the
       | "DuPont" to apparently differentiate between these new clones and
       | the previous, officially made, "Berg" connectors.

           | Perhaps that's the "nuance" you were referring to.

         | 
         | "Dupont" is exclusively a Chinese-ism in my experience, along
         | with saying "buckled" instead of "latched" and "welded" instead
         | of "soldered".

         | relatively recently and was surprised to find that reputable
         | vendors don't call them DuPont connectors, even in passing. As
         | far as I can tell, they have no name that everyone would
         | recognize and that lets manufacturers steer clear of naming
         | other companies, despite being so ubiquitous.
         | 
         | (I suppose this is a common problem with connectors. Someone
         | could tell me "it's a Molex connector", and I'd know what they
         | mean -- the one that supplies power to pre-SATA hard drives --
         | but of course Molex makes thousands of different connectors, so
         | it's really a terrible name for that one specifically.)

         | Long ago, if you mentioned "Molex" to someone like a TV

         | phenomenally wide range of offerings, but searching Google
         | Image for "molex connector" brings back some fairly consistent
         | connector types for the first page of hits.
         | 
         | It could be a case where a brand name carries a historical

               | that'd be the case if Kleenex made hundreds of
               | variations, and the variations had no cross-compatibility

               | 
               | People that want a 'molex connector' want, usually, an
               | AMP style press-lock 4 pin connector... unless they don't
               | -- they're looking for a molex MiniFit extension to reach
               | their GPU... unless they don't -- they want a vintage
               | Molex asymmetric 4 pin for an old legacy device.
               | 
               | 'Molex' is more ambiguous, imo, than you give it credit
               | for.
