      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.

    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.

    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 IRmys 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.

    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?

    • Silver Cymbal

      پیش 8 روز

      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.
