Surface contact card retention assembly

A retention assembly for securing a surface contact card in a portable electronic device, the retention assembly comprising:

• a main body defining a receiving groove therein;
• a pair of fixing members positioned on opposite sides of the receiving groove;
• and a locking member slidably positioned on the fixing members and adjacent to the receiving groove, the locking member being slidable from a first position at a side of the receiving groove to a second position on a top of the receiving groove, and being latched at the second position, thereby pressing opposite ends of the surface contact card;
• wherein the main body defines a mounting groove therein;
• the receiving groove is defined in a bottom surface of the mounting groove;
• wherein each fixing member comprises a limiting portion, and defines a recess in a bottom surface of the limiting portion;
• the limiting portion and the bottom surface of the mounting groove cooperatively define a sliding groove there between;
• a sliding block is formed on the locking member;
• the sliding block is slidably inserted in the sliding groove;
• and wherein each fixing member comprises a connecting portion extending substantially perpendicularly from the limiting portion;
• the connecting portion has a stepped surface;
• a latching groove is defined in the stepped surface;
• a latching protrusion is formed on the locking member to engage in the latching groove.
