a socket body defining a mating surface and an opposite mounting surface, a plurality of passageways extending obliquely from the mating surface toward the mounting surface;

at least two terminals insertable into a same passageway, each terminal including a long resilient contact arm and a short resilient contact arm extending in parallel to each other, the long resilient contact arm and the short resilient contact arm laterally and resiliently engagable with opposite slanted inside walls of the passageway by a spring package contact section formed therebetween so as to retain the terminal in the passageway, each spring package contact section of said at least two terminals extending above the mating surface for electrically mating with a common contact pad of an IC package;

the long resilient contact arm further including a board contact section formed at a free end thereof and located opposite to said spring package contact section, each board contact section of said at least two terminals extending below the mounting surface for engaging with a common conductive element of a printed circuit board, wherein the long resilient contact arm and the short resilient contact arm of each terminal are floatably moved in a same direction relative to the corresponding passageway.
