Charge your electric vehicle with USB-H (“H” for Huge)
Comment on USB inventor explains why the connector was not designed to be reversible

they should just go with perfectly circular, with different sizes for different applications. imagine a 10mm unit - high power/bandwidth hoses with a satisfying locking mechanism that magnetically seals the connection.
and makes the proton pack sound. and rgb fuck nevermind go back this was a bad idea

this, but the plug in and unplug sounds should be 40db louder.

Wouldn’t fit very well into something like a smartphone though

We could have a compact version, say 3.5mm, with different segments to carry different signal types. More segments can be added to allow for additional features. It could work with audio, video, power, and other data transfer. That would fit ideally into a phone.

Sounds like TRRRRRRS
Smokeless7048@lemmy.world 1 year ago
i mean, USB 1 and 2 are just 4 conductors, so TRRS.
USB-C can have up to 20, so TRRRRRRRRRRRRRRRRRRS

I love circular connectors that screw onto the receptacle or have locking tabs

This is why I only buy cell phones that have BNC connectors.

MIL-DTL-38999 for everything, including steampunk phones!

They’re great, rugged connectors. But they’re even more annoying to align than USB in my experience.

You say bad idea, I say sign me up!

Circular isn’t a great idea, and here are most of the idea why it is not : …stackexchange.com/…/why-dont-we-have-a-circular-…
USB required to have a stable connexion, as it’s a digital signal and not an analog as jack ports, which just sends curent through it. Rotating the connector could maybe introduce issues for signal integrity.
The usb connector has much more connectors than a jack port. It would take a very long hole to fit them all. (usb 3+, usb C…)
Size constraint. USB C is flat, a round port is not. So it’s bigger in 1 way, but smaller in the other, and so creates more design challenges.

Round is not round, that is, there’s a difference between the likes of cinch and DIN (-style) connectors. Cinch can be rotated once inserted which indeed isn’t ideal, but DIN are perfectly adequate signal-wise and you can rotate them into place, just like finding the begging of a thread when inserting a screw.
Keyboards used five-pole DIN for the longest time and mice D-Sub (because serial), both changed to Mini-DIN 6, aka “PS/2 connectors”. And never, ever, did anyone complain about getting the orientation wrong with DIN connectors.
D-Sub are a bit iffy but at least you really do have a 50/50 chance as they don’t jam like USB-A does. They also aren’t actually rectangular and you can feel the matching angles on both female and male ends.

Hah! Hardly. I have plenty of memories of endlessly rotating mouse and keyboard connectors as I reached behind a computer trying to insert it blindly, and somehow having to try half a dozen times before it finally found just the right orientation.
There’s also the issue on the older, large DIN connectors of pins getting bent or broken.
We moved on from those things for darn good reason, and I for one have no interest in going back.
barsoap@lemm.ee 1 year ago
I never bent a pin and as said, you can just turn them and at some point they’ll align.
The main downfall of DIN was foreign hifi companies standardising on cinch and SCART and German hifi manufacturers then switching over. You’ll still see them in niche applications, though, probably the most common is MIDI.
