I just watched a TikTok about how people used to plug in things to their light sockets when electricity was first becoming popular. And they kept calling the plug a light socket, what rule says it’s not a plug that screws in? And why shouldn’t plugs screw in? We have material science to make plugs and cables hard enough that if you kick the wire it still doesn’t come out. Electrical connections should be more secure. That’s all I’m saying.
Plugs can be more secure, but they also can’t.
You don’t want plugs to be too secure because they’re supposed to be temporary. Plug in fast, unplug fast.
There’s a benefit to plugs that come off easily: That’s the weakest point. If you kick a cord, the cord doesn’t snap, it just comes unplugged. If you make your plug stronger, maybe instead the cable breaks and now you’ve got lethal voltage swinging around, or you have arcing inside a connector or inside a cable that starts a fire.
There are electrical connections that are more secure used in industry or other places. For example DIN plugs or Brad Harrison connectors.
My guess to the biggest reason not to do this is safety - if somebody is being electrocuted, you want to be able to pull the cord out of the wall as quickly as possible to maximise their chance of survival.
… because they’re supposed to be temporary. Plug in fast, unplug fast.
Some are supposed to be temporary. Others are meant to be more permanent.
But anywhere a plug is permanent, like an entertainment center, it’s not in a place where it’s in danger of being jostled. So there’s no need for a stronger attachment.
Cause if something catches and pulls hard on the cord you would prefer it yank the cable out of the socket and you just plug it back in, rather than either strip the screw and ruin the socket or even pull the entire socket out of the wall. Or if you trip on that cord its much safer for you to have that cord come out and only trip you a bit than it catch, go taut, and send you falling on your face.
This. They make twist lock receptacles, for certain applications. Normally in commercial settings where small appliances are powered by ceiling mounted outlets.
Yeah, think about a child tripping over a cord. Do you want it to come unplugged or pull down the crock pot, coffee pot… This is also why they put short cords on hot stuff.
Your foot catches the cable. It’s immediately taut. Your leg’s caught and you start to fall. Right then, this drywall gives way and the cable, the socket, and a big chunk of drywall come flying forward and crack the back of your skull. You’re out cold.
The exposed wiring touches the pile of foil bags you were carrying. Electricity arcs through the stack igniting the entire thing instantly.
The plastic is burnt off in a toxic cloud, which engulfs everyone present.
In his microplastic gas stupor the first guy to pull out his phone drops it. The wildly oscillating cord being pushed around by boiling steam happens to land on both sides of the phone and sends a vicious arc through the case. The battery overheats and explodes, injuring the cat.
Nice work, screw-in plugs. Nice work indeed.
If you’re ripping out drywall because you tripped over a twist lock cord, something (the outlet box) definitely wasn’t installed correctly.
Because it’s better for a plug to pop out the socket then the socket come out the wall when someone trips ok a wire. Or you could just use a sensible design like the British plugs that have the wire coming out the base and three pins to hold it secure.
I can see multiple reasons:
- trip hasard
- could break the cord or the device if it gets yanked
- less convenient, slower
- it would tangle/twist the cable
It’s a lot harder to stick something, like your fingers, into a small hole than a light socket.
And what if you need to unplug something quickly?
Are you high? Who in theie right mind thinks this is a good idea?
If your appliance or electronic catches fire the first thing you should do it unplug it if you can. You can’t do that with a screw plug.
You know when you are screwing in a blub without turning off the switch how the blub will blink a few times while you are screwing it in? Most electronic don’t like that.
They do make twist in plugs…
Your standard (north american) plug is a NEMA 5-20R… the twist in (locking) variant is NEMA L5-20R.
I see locking plugs most commonly used in applications where the cord may have a bit more force to it… example: a ceiling mounted receptacle serving movable furniture/equipment.
Theyre not used for standard domestic applications for all the reasons other userd indicated in this thread.
They exist and have done pretty much since the screw in light socket (ES) was invented.
The cord would get all twisted up
There are a lot of valid reasons not to do a screw in plug, but hoses solved this problem decades ago. The top turns, the cord doesn’t
One reason would be so that if you needed to unplug something quickly, you can do so. Also you wouldn’t be able to have so many different variations to differentiate the different amperage and voltages. Most residential dwellings (in U.S.) only use 15A or 20A 120V receptacles, but there are plenty of other different types that use horizontal or verticle or even anhled slots. Think of a 240V air conditioner, it has a different type of plug so you don’t accidentaly plug it into a 120V receptacles. If needing something more secure, you can always get a twist-lock plug.
Maybe you want it to release. Mac did that with their laptop in the early ‘00s and it was really handy.
Look up IP66 rated single plugs and 3 phase plugs. I use that every day.
