A set of pcb board, including the first pcb board and the second pcb board；
A strip through-hole is at least opened up on first pcb board, the both sides of the strip through-hole offer symmetrical card slot；
The edge on one side of second pcb board is equipped with the projection coordinated with the strip through-hole, and the projection is equipped with
The screens vertical with second pcb board；
The card slot of first pcb board is equipped with round recess perpendicular to the side wall of the first pcb board plane；
The screens surface of second pcb board is equipped with recessed with the circle on the side wall of the card slot of first pcb board
The matched round bump in position.
Wherein, the number of first pcb board is one, and the number of second pcb board is two or more.
Wherein, even number strip through-hole is offered on first pcb board, on the edge on one side of second pcb board
Equipped with two projections.
Wherein, the both sides of the strip through-hole are respectively equipped at least four card slots.
Wherein, the symmetrical card slot gap width of strip through-hole both sides is 2mm, and the thickness of the screens is 2.05mm,
The screens is interference fitted with the card slot.
Wherein, the round recess surface is smooth cancave cambered surface, and the surface of the circle bump is smooth spherical cambered surface.
Compared with the prior art, a set of pcb board of the utility model is equipped with card slot and screens, passes through round concave point and circle respectively
Shape bump cooperates, and simple in structure, inserting mode is secured.
