      summary: the holes are almost never (purposely) used to secure the plug in the socket. it is often just for manufacturing reasons (but not always, as in this case). it is included in the specifications as an optional feature, so that the holes are not made too big, or in the wrong place.

        I’m curious why he doesn’t talk about all the patents that specify locking as a feature. Even modern patents reference the features of older ones in their designs if they use them.

        He used all modern plugs you would find on houses in 2000+, of course none of them lock the old way. Go grab some from the 20s and 30s.

      In the cheap one, we have two perfectly flat brass pieces pressing against each other.

      I’ll bet you any ammount you want, that’s not brass. It’s iron with brass coating.

      There is no finite life span on any connector.

      You obviously haven’t used a Cannon or a Neutrik made XLR connector. I have one from the 1970s, it still works like a chram.

      Also, take a look at some of the Type F power plugs. If that’s not robust, IDK what is.
