    • Its there to have a Tighter fit in the plug... if it wasnt there it would just slide out with ease!!! Thats why the holes are there.. Sounds Dumb, punching a hole through it bends the metal so it locks in the plug.

    • @Víðarr Kerr - From what I understood from the video, the holes themselves were a derivation of the small indentations from the original design by Hubbell. Other companies worked around Hubbell's design with the holes so they wouldn't have to pay Hubbell for his work. Both the small indents and the holes were there to secure the plug into the outlet so it wouldn't pull out easily. Modern day outlets, however, don't have any internal design that utilizes the holes in plugs to secure them in place. The holes are in fact obsolete or serve no purpose but we continue to use them because that's what people are conditioned to see. The prongs of plugs could be completely solid (no holes) and they would work just fine.

  • I wish outlets would have a click into place and you'd have to press an eject button to remove them, that would save many people from accidentally unplugging it, and it would put the stress on the pegs going through the connector, not the friction-fit connectors, and they'll be less likely to loosen over time.

  • Long ago (around 2007 or something back when SEworld video responses were still a thing), I saw a fake tutorial saying that you could power a TV off a AA or AAA battery. The method was to use RCA jacks in the power plug holes and the other ends using a battery. Something like that. Of course, people tried this and it didn't work, including someone using a video response.

  • Where I work, we have this old extension cord which has a lever you can flip which locks the plug into the cord so it can't fall out. I'm sure it utilizes those holes for that purpose. I wish this feature were present on more extension cords!

  • First of all, no such word as "indention." You were probably thinking of "indentation." Secondly, the holes were used in the early days to help remove any corrosion on the socket contacts as the plug would be inserted and removed.

    Richard IredaleRichard Iredale3 dagar sedan
    • The original patent documents clearly describe the holes as the retention mechanism the corrosion ability is a myth with no documentation supporting this.

      Silver CymbalSilver Cymbal3 dagar sedan
  • It's interesting that the holes were originally used to keep the plug from falling out. The real question then is when and why did the manufacturers stop making sockets to take advantage of that design feature?

    rlitz99rlitz993 dagar sedan
    • That's the question I spent hours on. I believe it ended around the 50s, I could not find any example outlets after that with the prongs in use and because so many companies made outlet it varied per brand so one brand may have kept it going longer. The standard itself never actually changed and since they weren't required they likely just stopped using them.

  • Actually, there are some extension cords that use a locking female end. I've seen it several times as a commercial electrician. Certain drop course utilize those holes and when you plug it into a locking extension cord it does not allow the end to be pulled out accidentally. You have to pull back a release collar to be able to unplug your device.

  • I always thought those holes were a manufacturing thing. My company molds connectors and we have some electrical contacts with holes like these. They are inserted into the mold tooling and a pin is dropped into the mold and through the holes. This secures the pins in place and keeps them from sliding back during the molding process since there is a lot of pressure inside the mold cavity that wants to blow the cable out, resulting in short contacts. But these particular plugs are often molded in low-pressure machines, so sliding contacts isn't really that big of an issue. I still wouldn't be surprised if some manufacturers use the pin method since it's a quick and easy way to eliminate a mode of failure which reduces scrap.

  • It must have been a poorly interpreted engineering proposal, right? Like it was supposed to indicate a bump from the inside to the outside to create a standardized kind of friction (instead of the offset lines along the length of the prong), and manufacturers just punched holes instead. Right? Or... What I wonder is if the design difference has a substantial effect on grip within the socket. I could have sworn I remember there being certain outlets from 30+ years ago that would lock or grip so tightly you'd risk yanking out the socket. Maybe the hole on the plug was supposed to match up with a bump on the outlet (which may or may not have been standardized in all aspects), which got phased out over time or never got adopted in the first place because...whatever...or people got sick of accidentally yanking out sockets and the fire risk wasn't worth it.
