Abstract:
1. A board-to-board connector, comprising a receptacle connector adapted to be mounted to a printed circuit board, the receptacle connector having: a receptacle housing having a base board, two first sidewalls protruding upward from two opposite sides of the base board, at least one pair of adjacent third sidewalls being substantially parallel to the first sidewalls and disposed between the two first sidewalls, a first checking window penetrating the base board and being located between the pair of the adjacent third sidewalls, the third sidewalls defining a plurality of first cavities therein, a receiving recess being formed between the first sidewall and the third sidewall; and a plurality of first terminals received in the corresponding first cavities, each of the first terminals having a first soldering portion adapted for being soldered to the printed circuit board, the first soldering portion stretching into the first checking window so as to check the solderability thereof with the printed circuit board; further comprising a plug connector adapted to be mounted to a respective printed circuit board, the plug connector having: a plug housing mating with the receptacle housing and defining at least two longwise rows of second sidepieces respectively fitted in the corresponding receiving recess, each of the second sidepieces longwise defining a plurality of second cavities therein; a plurality of second terminals received in the corresponding second cavities, each of the second terminals having a second soldering portion adapted for being soldered to the respective printed circuit board; and wherein the plug housing defines a second checking window extending longwise and penetrating the plug housing, the second checking window is located between the two second sidepieces, the second soldering portions stretch into the second checking window so as to check the solderability thereof with the respective printed circuit board, the third sidewalls of the receptacle housing are inserted in the second checking window.
