power supply - Name of the HP Female Adapter Socket In My Laptop

I have this HP powerbrick with a 90W capacity (19v 4.7A) that I want to use in my project. I am planning to use it as a power source for my 50W LED. But I want to keep the male socket it has rather than chop it off.

What I need is to know what specific socket name should I search in EBay to use it? Or can anyone recommend me a link and I can search it from there.

I search for HP Power socket and I get this result: http://www.ebay.ph/sch/i.html?_from=R40&_sacat=0&_nkw=HP+power+socket&LH_PrefLoc=2&_arm=1&_armm=63&_ruu=http%3A%2F%2Fwww.ebay.ph%2Fsch%2Fi.html%3F_from%3DR40%26_sacat%3D0%26_nkw%3DHP%2Bpower%2Bsocket%26_arr%3D1

I'm not sure if this is what I am looking for.
