When the accommodating case 2 is to be pushed into the accommodating body 1 (as shown in FIGS. 5 and 8), the positioning groove 27 of the accommodating case 2 is engaged with the sliding block 151. The elastic positioning protrusion 1511, the pushing groove 28 of the accommodating case 2 pushes the pushing protrusion 1512 of the sliding block 151 and compresses the sliding piece 151 to the spring 153, and the front end of the guiding rod 152 The hook body moves backward through the left side of the annular guiding groove 1152. When the accommodating case 2 is released, the spring 153 pushes the sliding block 151 and drives the hook body of the guiding rod 152 to move forward. The hook body is positioned in the opening of the V-shaped guide post 1153 to position the accommodating case 2 in the accommodating body 1 . When the accommodating case 2 is to be pulled out of the accommodating body 1 (as shown in FIGS. 8 and 5), the accommodating case 2 is first pressed first, and the accommodating case 2 is inserted. The pushing groove 28 pushes the pushing protrusion 1512 of the sliding block 151 and drives the sliding block 151 and the hook body of the guiding rod 152 to move back to move the hook body out of the opening of the V-shaped guiding column 1153. And then releasing the accommodating case 2, the spring 153 pushes the sliding block 151 and the accommodating case 2 forward, and the hook body of the guiding rod 152 passes through the right side of the annular guiding groove 1152 Moving forward, at this time, since the elastic positioning protrusion 1511 of the sliding block 151 is still engaged with the positioning groove 27 of the accommodating case 2, the accommodating case 2 does not directly rush out of the accommodating body 1 The buffering function is applied, and then the user can pull out the accommodating case 2 to disengage the positioning groove 27 of the accommodating case 2 from the elastic positioning protrusion 1511 of the sliding block 151, thereby enabling the user to The accommodating case 2 takes out the memory card or inserts the memory card into the accommodating case 2.

Referring to FIG. 1 , FIG. 3 , FIG. 4 , FIG. 7 , FIG. 9 , and FIG. 15 , as shown in the figure, in the above-mentioned memory card connector, the receiving body 1 may have a plurality of fixed positions. Columns 16, the fixing posts 16 may be located above the upper casing 11, especially the front side of the upper casing 11, in the figure showing two fixing columns 16, the number of the fixing columns 16 may also be practical Need to increase. When the memory card connector of the present invention is to be fixed on a circuit board (not shown), the receiving body 1 can first be disposed on the two fixing holes of the circuit board (not shown).
