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.

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

Are you high? Who in their right mind thinks this is a good idea?

Basically that weak contact before the device finishes being screwed in would cause a lot of arcing which would definitely cause a short circuit and would definitely trip your breaker almost constantly. The reason lightbulbs can be screwed in is not so much that it’s a convenient way to design an installable electronic but more that lightbulb companies wanted to create a design that would be so easy to replace any person could do it without any training.

So Edison hired a team of engineers to design an easy and safe application and they made the screw in application such that the contact would only get close enough at the very end of screwing and so that none of the metal would be able to contact human skin, avoiding electrocution and minimizing arcing.

For literally any higher draw application this would cause arcing so intense it would flip a breaker or possibly destroy the device and cause a fire. If you want a real life example just take a portable heater, set it to on and plug it into the wall but make that plugging motion last 3-5 seconds. WARNING you will at the very least flip a breaker and at the worst cause a fire and destroy your wall outlet, so don’t actually try this at home lmao

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.

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?

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.

Maybe you want it to release. Mac did that with their laptop in the early ‘00s and it was really handy.

For what benefit?

Rather have a plug pull out of an outlet than it ripping the cable out of the housing of the equipment it is in or cause other damage. But more importantly, we do have connectors that let you screw in a plug (or have a latch or other locking mechanism). Very common on higher voltage equipment in industrial applications. But again, what is the benefit for day-to-day use for regular devices? Plugs don’t just fall out of outlets on a regular basis. This isn’t really a problem that needs solving.

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.

Look up IP66 rated single plugs and 3 phase plugs. I use that every day.

Because that would be a significant fire risk and would definitely result in a lot of people dying over they years. You need to be able to quickly unplug something in an emergency.
