Abstract:
1. An electrical connector for connecting a CPU (central processing unit) with a plurality of solder balls to a PCB (printed circuit board) comprising: an insulating housing having a plurality of passageways; and a plurality of terminals received in the corresponding passageways and each including a base portion having an upper surface and a lower surface opposite to each other, and a plurality of holding portions extending from the base portion; wherein each terminal has a plurality of upper hands bent upwardly from the base portion and a plurality of lower legs bent downwardly from the base portion, wherein the upper hands bent inwardly from the base portion, and wherein the lower legs bent inwardly from the base portion, wherein the electrical connector also includes a plurality of fusible members attached thereto and the lower legs of each terminal defines a second receiving space with the base portion for receiving the fusible member, and the upper hands of each terminal defines a first receiving space with the base portion for receiving the solder ball of the CPU, wherein each upper hand has an upper clamping portion at a free end thereof, and wherein the upper clamping portion has a first inclined surface for guiding the solder balls of the CPU to the first receiving space, wherein each lower leg has a bottom clamping portion at a free end thereof, and wherein the bottom clamping portion has a second inclined surface for guiding the fusible member into the second receiving space.
