What do you call this kind of power cable?

It is round and square. I just want a 10-12ft one to replace the 6ft one that came with my TV.

 

This is a very rare plug in my household lately. But occasionally it pops up in a few electronics. I've only seen it a few times typically in electronic things like boom boxes and lastly on my old DVD player.

 

I have an external drive that uses it to go from the wall to it's PSU, seen it in other adapters for small electronics.

 

Polarized C-7

IEC 60320 - Wikipedia, the free encyclopedia

 

I can't seem to find it anywhere longer than 6 feet! I hate extension cords if I can help it. This TV is mounted to the wall in my kids' room, and surge strip is on the floor behind the dresser and the way it's routed it needs to be at least 8-9 feet long. Using an extension cable right now, but would prefer a single cable. Thanks for the help NBRians!

Pick your waiting time

 

Thanks. I checked there but guess I wasn't searching for the right thing.

 

I tend to have the same problem when looking for oddly specific cables, but the better sites will recognize the official name of a cable, assuming there is one for what you're looking for

As far as it being non-polarized, I don't think it would matter too much, but most of the time cables will have one side marked or colored and the other unmarked/uncolored, so you can at least match it like that if you're worried about it.

 

Those have two rounded nodes, rather than one rounded and one squared off like HTWingNut's. Piecing together info from this thread and the item descriptions, it sounds like they're non-polarized versions of what he's looking for, where the non-parallel format of his connector ensures that the cable is plugged in with the correct polarity. Would a non-polarized cable work on a system that's fitted with a polarized connector? It should plug in and deliver power, but would the non-polarized power input be harmful to the TV?

edit: looks like you beat me to it.

 

Assuming they're LCD's, they run off AC and convert to DC for the internal components anyway, but there are picky devices that won't work unless you plug them in the right way. I've also seen some plugs that only have the rounded edges anyway, which I think is more common with newer devices (My PS2's power brick is the main one I remember, but I believe the fat PS2 also only has rounded ones).

I doubt anything would catch fire from using these plugs reversed would even use this type of cable for that reason alone (risk of easy reversal), hopefully over-designed to just not work instead of taking power backwards

 

My knowledge is a little bit limited about this stuff - regardless of the head, the power cable is necessarily polarized simply by the nature of how it works, right? If so, marking the cable and/or head with white-out or anything else to indicate which side corresponds to the squared-off side of the original cable should suffice, since that would ensure that you were matching the polarity in the same way the original cable delivered it.

 

Not to say I'm an expert on electrical devices myself, but yes that would work. It's not like they put chips in the cables that sense whether its plugged in wrong or not. I believe the polarization is more due to safety reasons. If I had to guess the internal ground on devices that use the square-round plugs are probably grounded to the neutral wire so they could cut costs and not have to use 3 prong plugs.

Or something like that? Maybe I'm just making a fool of myself

 

obviously a new TV is needed in this case

 

Indrek, I like your well thought out post - but miro_gt has it right:

HT Needs a new TV!!!

 

LOL. This *IS* a new TV that Santa brought the boys. I may try that Monoprice one. It's cheap and I need to order a few more cables anyhow (ethernet, SATA) and they only charge by weight. I can't believe this isn't an easier to find power cord in longer lengths.

 

Well, we've already figured out it won't cause the end of the earth, I doubt you'd find it for too much cheaper outside of trash picking

 

I mixed the square/round cables once because I couldn't find the other and it worked fine. i just looked at it and thought, hmm...? I crossed my fingers and voila!

At the time, I really wanted to watch that DVD and the player was obsolete so if it blew up, I would be bothered much. It worked fine. But this is my personal experience and NOT AT ALL SCIENTIFIC so you need to be aware of that.
