Patent ID: 7387540

Claim:
An electrical connector assembly for connecting a first and a second circuit boards, comprising: a male connector for electrically connecting to the first circuit board, comprising: a plug insulator having a base portion, a plurality of side walls surrounding the base portion to define a cavity therein, and a plurality of passageways communicating with the cavity and extending throughout the base portion; and a plurality of male terminals retained in corresponding passageways, each male terminal comprising an engaging portion exposed in the passageway and a tail portion for soldering onto the first circuit board; and a female connector for electrically connecting to the second circuit board, comprising: a receptacle insulator for mating with said plug insulator, the receptacle insulator comprising an island portion defining a plurality of grooves, a plurality of periphery walls surrounding the island portion and defining a plurality of channels, and a pair of slots defined between opposite sides of the island portion and corresponding periphery walls for insertion of corresponding side walls of the plug insulator, and a plurality of female terminals retained in the slots, each female terminal comprising a contact portion for contacting with a corresponding engaging portion of the male terminal and inserted into the passageway within the base portion, a resilient portion resiliently connecting to the contact portion, a soldering portion for soldering onto the second circuitboard and an insertion portion inserted into the channel, said resilient portion comprising a horizontal resilient beam and a bent compressible portion resiliently connecting to the resilient beam and having a bending portion away from the engaging portion of corresponding male terminal for providing elasticity to the female terminal.
