Mother board assembly

A mother board assembly, comprising:

• a mother board having a top face and a first connector mounted on said top face;
• a first mounting seat mounted on said top face of said mother board on one side of said first connector and including at least one resilient first positioning member, said first positioning member being substantially C-shaped and defining a first groove therein, said first positioning member having two spaced free ends which define a first access into said first groove;
• a second mounting seat mounted on said top face of said mother board on the other side of said first connector, said second mounting seat being spaced from and being disposed opposite to said first mounting seat, said second mounting seat including at least one resilient second positioning member which has a substantially U-shaped retaining portion that defines a second groove therein and that has a second access into said second grove, said second positioning member further having a curved plate portion extending upwardly from said U-shaped retaining portion in a direction away from said first mounting seat;
• an interface card having a front end, a rear end, a bottom face and a second connector mounted on said bottom face between said front and rear ends;
• said front end of said interface card passing through said first access into said first groove so as to be clamped resiliently between said free ends of said first positioning member, said rear end of said interface card being pressed downward so as to slide along said curved plate portion and extend into said second groove through said second access in order to be retained in said U-shaped retaining portion, and said second connector of said interface card mating with said first connector of said mother board so as to achieve electrical connection between said interface card and said mother board.
