    • 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.

  • Despite your global survey - looking at a few sockets - most older socket designs included either a spring loaded ball bearing or a bump on the socket's wiper blades which enabled the hole in the plug to "click" into place, making it more difficult for the plug to fall out. While it is not "required" according to NEMA, it does state that if it is there it must be a certain size and in a certain place. It is therefore logical that while the hole is not a requirement it was at some time at least an "option". Before standardisation as we know it patent apps included the hole as a method of retaining the plug in the socket. When NEMA came along and started telling everyone how things should be done they had to cater for a large number of designs that were already out there - hence the line stating that if you put the hole in it should be this big and here. Do you really think that companies like Apple and Samsung would got through the hassle of putting holes in their adapter blades if there was no reason for it? This reinforces the age-old maxim "Just because you haven't seen it, doesn't mean it doesn't exist".

  • They act as a catch so the plug cannot fall out. It’s friction/press Not Mechanical. The hole is round Not square because it’s easier to drill out a round hole than to punch out a square hole.

  • I have a pull down cord reel that has an outlet on the end, It has a locking outlet, so that it can't come unplugged. you have to press a button on the outlet for it to release what is plugged into it. ( If the plug has the holes in it )

    Ray S.Ray S.7 dagen geleden
  • Huh? The hole is drilled out, no? So companies wouldnt have to "add" the material back in. It would technically be one less step in the process to leave the prongs solid throughout. Less machines, time, and probably saves money. And im pretty sure (nowadays) the holes are used to connect/extend wires without having to cut and splice a perfectly good cord. They used to be for pressure fittings to hold the plug in the socket but modern socket designs have made it unnecessary

  • 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 NLworld 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.

  • 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 Iredale11 dagen geleden
    • The original patent documents clearly describe the holes as the retention mechanism the corrosion ability is a myth with no documentation supporting this.

  • 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?

    rlitz99rlitz9911 dagen geleden
    • 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.
