Please note that although the first receiving groove 1131 and the second receiving groove 1132 are designed to protect the first elastic arm 1144 and the second elastic arm 1145, the present invention does not limit that a resilient arm must be placed in the middle of a guiding member. Inside a receiving slot of the slot. According to the method of the present invention, a guide without a groove is sufficient to protect a resilient arm. Further, when a metal reinforcing member is attached to a tower portion, as long as a resilient arm is adjacent to or abuts against a guiding member having no groove, the guiding member without the groove is sufficient to protect the elastic arm. The elastic arm is not deformed by extrusion.

Taking the first elastic arm 1144 of FIG. 9 as an example, if the first guiding member 1125 of the first tower portion 112 has no groove (ie, there is no first receiving groove 1131), then the first elastic arm 1144 is laterally adjacent. Or against the first guiding member 1125, and whether the first resilient arm 1144 is immediately adjacent or abuts against the left side of the first guiding member 1125 (near the side of the card slot 111) or the right side (near the first lock) Side of fastener 116), first guide The piece 1125 is sufficient to protect the first resilient arm 1144 without the first resilient arm 1144 being squeezed. Similarly, the second resilient arm 1145 also has similar technical features. Therefore, the use of a guide member (with or without a groove) to prevent deformation of a resilient arm is also within the scope of the patent application claimed herein.

It can be seen from the description of the first embodiment that the first elastic arm 1144 and the second elastic arm 1145 of the present invention only have the first clamping portion 114b and the second clamping portion 114e extending into the guiding groove 1129, so the present invention In addition to making the insertion of the electronic card 2 more stable, shockproof, and anti-sway, the first elastic arm 1144 and the second elastic arm 1145 can prevent the first elastic arm 1144 and the second elastic arm 1145 from being under the electronic card 2. The edge 21 is pressed and deformed. In addition, the first metal reinforcement 114 of the present invention is bridged between the first sidewall 1121 and the second sidewall 1122 of the first tower portion 112, so the first metal reinforcement 114 can also strengthen the first sidewall 1121 and the second The tensile strength between the side walls 1122 prevents the electronic card 2 from squeezing the connecting wall 1130.
