ABSTRACT:
An electrical socket (10) includes an insulative housing (12) with cavities (14) extending vertically therethrough and a plurality of contacts (30) retained in the cavities (14), respectively. An engagement bar (22) is positioned proximate the upper open end of each cavity (14) so that when the contact is assembled in each corresponding cavity (14), the front portions of the spring arms (40) of each contact (30) can move along a guiding pin (62), which is inserted into the cavity (14) from the top open end temporally only for the sake of assembling of the contacts (30) within the socket (10), and be deflected outwardly so that the tips (44') of the spring arms (40) of the contact (30) can pass the engagement bar (22) and be positioned by the sides of the engagement bar (22). Therefore, the tips (44') of the spring arms (40) of the contact (30) can abut against the opposite sides of the engagement bar (22) when the guiding pin (62) is removed from the socket (10), and a larger space is formed between the contact sections (42) of the spring arms (40) of the contact (30) for easy and low insertion force of the pins downward extending from the PGA component.
