Does anyone one know what this socket thingy is inside glovebox of my 2006 focus LX?😊

It's a vent for the cooled glovebox i think.   

Mines on the side rather than back on the facelift model though.

Definitely for glovebox cooler.
Tbh, cars with it fitted are rare.
If it was connected up you'd have a rotating vent cover over the hole.

It makes a handy wire path for any accessories to be hidden away. Just as long as your garage doesn't like removing your glove box to get to the air filter 

My MK2 Ghia has/had the air conditioned glovebox, IMHO it's a stupid idea and disconnecting the pipe to remove the glovebox is just another fun step when trying the change the pollen filter!

1st time I did the pollen filter the pipe got removed and where it connects to (not the glove box end) plugged.  I always wondered what Ford thought people would actually use it for as most people don't drive around with the AC on all the time?

OTOH... I like the chilled glovebox, particularly in summer if you want a cool drink...  Had one in both an Octavia and Exeo...

 

As for "most people don't go around with the AC on"... also disagree, the aircon dries the air and prevents interior fogging dramatically.  I just dial up the temp I want!

I use it for keeping my handbook cool...   But seriously, I do find it useful for a bottle of water in summer lol.  The pipe is still in the way of the pollen filter though, even though they moved the vent port on facelift, I don't bother removing it, just bend it out of the way as it's thin and flexible. 

They don't fit them at all to mk3 as far I've read...apparently there was an issue with condensed water dripping into the GEM or something...
