Subject: Re: [LIB] 50/70 plug dimensions part# needed

I know it's cheating but I've had no problems plugging the L50/70 power 
supply (actually it's the same as several other Toshiba 15 volt plugs such 
as the Portege) into a chassis mount 2.5mm DC power socket (the Libretto 
plug seems to be a standard 3.1mm (inner diameter) DC plug you can get from 
your average electronics enthusiast store such as 
http://www1.jaycar.com.au/productView.asp?ID=PP0513&CATID=35&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=651,
 
or at least I've been using a standard 3.1mm plug first with my L50 and now 
with my Portege 7220CTe when I was tapping the power line for running other 
things and it's had no problems ... funny how they sell the plug but not 
the socket).

The type I'm talking about is the open frame type as in 
http://www1.jaycar.com.au/productView.asp?ID=PS0518&CATID=35&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=651
 
... you might need to squeeze the 'spring' contact a little with a pair of 
pliers first and after you use it with a 3.1mm plug it probably won't hold 
a 2.5mm plug very well but it works a treat! Pitty it isn't line though 
(and can get a little bulky as line) ....

P.S. As for tapping into L100/110 supplies (and some of the Porteges like 
the 3110), I find a standard 2-pin header (the sort you put jumper caps on 
in computers) works nicely if you cut about 1.5mm off the ends (and for 
plugging into the computer side, a 2 pin header plug filed down on the 
sides and with a little bit of plastic superglued to provide a polarity key 
works real nicely.

P.S.S. All this I'm assuming you're actually looking for the male connector 
(the computer side) and not the female connector (the power supply side)? 
Especially with concentric or jacketed connectors it can get a little 
ambiguous but I find a general rule of thumb that you look for the smallest 
pin or hole in a concentric connector, if it's a pin it's male and if it's 
a hole it's female.
