Electrical connector assembly having board hold down

An electrical connector assembly comprising:

• a printed circuit board;
• a card edge connector located on one position of said printed circuit board;
• a board hold down located on another position of the printed circuit board far from said one position in a front-to-rear direction;
• and
• a daughter board parallel disposed above said printed circuit board, said daughter board including a first end connected to the card edge connector and a second end, opposite to said first end, latchably engaged with the board hold down;
• wherein,
• said daughter board defines a through hole proximate said second end, and said board hold down extends through said through hole;
• wherein the board hold down comprises an immovable pivot bracket secured to the printed circuit board and a movable latch pivoted disposed on the bracket, the latch abutting against a top face of the daughter board for preventing upward movement of the daughter board.

A method of assembling a daughter board to a mother board in a parallel relation, comprising steps of:

• providing a mother board with a card edge connector at one position and a board hold down at another position spaced from said one position, said board hold down comprising an immovable bracket secured to the mother board and a movable latch pivotally mounted to the immovable bracket;
• providing a daughter board with a through hole proximate one end thereof;
• inserting another end of the daughter board into the card edge connector and downwardly moving said one end of the daughter board toward the mother board in a rotation manner until the movable latch extends through said through hole and the daughter board is moved to a parallel position with regard to the mother board;
• and
• pivoting the latch to a locked condition in which the latch abuts against a top face of the daughter board to secure the daughter board in the parallel position relative to the mother board.
