Claim 2:
3. A board-to-board connector which electrically connects a first board and a second board comprising:
a receptacle connector including
an insulative receptacle housing comprising a first bottom portion, first sidewall portions protruding along first opposite side borders of the first bottom portion and facing each other, the first sidewall portions extending along a longitudinal direction of the receptacle housing, second sidewall portions protruding along second opposite side borders of the first bottom portion and facing each other, each second sidewall portion being connected with each first sidewall portion, a center protrusion portion protruding from a center of the first bottom portion and having a plate insertion recess formed on a center thereof, the center protrusion portion extending along the longitudinal direction, and a first connection recess portion formed between the sidewall portions and the center protrusion portion, each sidewall portion having an inner surface facing the center protrusion portion, an opposite outer surface, and upper and lower surfaces extending between the inner and outer surfaces,
a receptacle metal shell configured to be soldered to the first board to fix the receptacle housing to the first board, and
a plurality of conductive receptacle terminals extending into the first connection recess portion; and
a plug connector including
an insulative plug housing comprising a second bottom portion, third sidewall portions protruding along first opposite borders of the second bottom portion and facing each other, the third sidewall portions extending along a longitudinal direction of the plug housing; fourth sidewall portions protruding along second opposite side borders of the second bottom portion and facing each other, each fourth sidewall portion being connected with each third sidewall portion, and a second connection recess portion formed between the third and fourth sidewall portions,
a plug metal shell configured to be soldered to the second board to fix the plug housing to the second board, and the plug metal shell having a first crosstalk blocking portion which is inserted into the plate insertion recess,
a plurality of conductive plug terminals extending into the second connection recess portion; and
wherein, when the receptacle connector and the plug connector are coupled to each other, respective plug terminals engage with respective receptacle terminals to form mating contacts, the first crosstalk blocking portion is inserted into the plate insertion recess, and the first crosstalk blocking portion prevents crosstalk.
