The card ejecting mechanism 3 is disposed in the accommodating space 11 and includes a lever member 31 and an operating member 32. The lever member 31 is located on the opposite side of the socket 12 and has a force receiving portion 311 , a force applying portion 312 and a shaft hole 313 . The force receiving portion 311 and the biasing portion 312 are respectively located at both ends of the lever member 31 , and the shaft hole 313 is located between the force receiving portion 311 and the biasing portion 312 . The lever member 31 further has a first surface 314 and a second surface 315 on opposite sides, and the shaft hole 313 extends through the first surface 314 and the second surface 315. The operating member 32 has a rod shape and one end abuts against the force receiving portion 311 of the lever member 31, and the other end is adjacent to the socket 12.

The shielding shell 1 has a top wall 13 and a holding structure 14 extending from the top wall 13 into the receiving space 11. The holding structure 14 has a shaft hole perpendicular to the top wall 13 and passing through the lever member 31. a shaft portion 141 of the 313, and two bearing portions 142 bent by the shaft portion 141 and extending in different directions. The two bearing portions 142 cooperate with the top wall 13 to sandwich the lever member 31 therebetween for holding The lever member 31 allows the lever member 31 to pivot about the shaft portion 141. In this embodiment, the holding structure 14 is formed by punching and tearing the top wall 13 , and the two bearing portions 142 are respectively bent and extended in opposite directions, and the two bearing portions 142 are at the lever member 31 and the The shielding shell 1 is inserted through the shaft hole 313 and then bent in the opposite direction, so that the first surface 314 of the lever member 31 abuts against the top wall 13 and the second surface 315 abuts against the two bearings Therefore, the lever member 142 is prevented from being easily detached from the shield case 1 and is less likely to be shaken up and down. Moreover, the length of the two abutting portions 142 can be longer to support the lever member 31 more stably. In addition, in the embodiment, the shaft hole 313 is circular, and the width of the shaft portion 141 of the holding structure 14 is close to the diameter of the shaft hole 313 to make the lever member 31 difficult to translate, that is, it is difficult to move back and forth. Thus, the lever member 31 can be stably held by the simple construction of the holding structure 14, and the holding structure 14 is convenient to manufacture and easy to assemble with the lever member 31.

Referring to FIG. 6 , in the embodiment, the shielding shell 1 further has a first blocking piece 15 extending from the top wall 13 , and the first blocking piece 15 is adjacent to the shaft hole 313 of the lever member 31 .

At the time, one side of the lever member 31 is entirely flat against the side of the tray 4. In addition, the lever member 31 further has a first recessed portion 316 for accommodating the first flap 15 , and when the tray 4 is located in the accommodating space 11 , the first recessed portion 316 is opposite to the first recessed portion 316 . A baffle 15.

Referring to FIG. 7 , in the embodiment, the shielding shell 1 further has a second blocking piece 16 extending from the top wall 13 , and the second blocking piece 16 and the first blocking piece 15 are respectively located under the force. The second blocking piece 16 is configured to limit the pivoting range of the force receiving portion 311 of the lever member 31 when the operating member 32 is pushed against the two sides of the portion 311. That is, when the tray 4 is to be withdrawn from the accommodating space 11, the user can push the operating member 32 to apply the force receiving portion 311 of the lever member 31 to force the force receiving portion 311 of the lever member 31. Pivoting away from the socket 12 and pivoting the urging portion 312 toward the socket 12, and pushing the tray 4 out of the socket 12, when the force receiving portion 311 of the lever member 31 abuts the second flap At 16:00, the pivoting can be stopped. In the present embodiment, the user can use a thimble 7 (see Fig. 1) to push the operating member 32. In addition, the lever member 31 further has a second recessed portion 317 that fits the second flap 16 so that the second recessed portion 317 is laterally abutted against the second flap 16 .

Referring to FIG. 6 and FIG. 7 , the embodiment further includes a detecting switch 5 including a fixed terminal 51 disposed on the shielding case 1 and a detecting terminal 52 disposed on the circuit board 8 . When the tray 4 does not reach the positioning in the accommodating space 11, the detecting terminal 52 is in contact with the fixed terminal 51 to form an electrical connection, and when the tray 4 reaches the positioning in the accommodating space 11, the detection is pushed. The terminal 52 is such that the detecting terminal 52 is separated from the fixed terminal 51 to form an open circuit.

In summary, the retaining structure 14 of the shielding shell 1 is disposed through the shaft hole 313 of the lever member 31 and the two bearing portions 142 are bent in different directions, and the lever member is shared with the top wall 13 31 is interposed therebetween, whereby the lever member 31 is less likely to be detached from the shield case 1 and is less likely to sway up and down. Moreover, the width of the shaft portion 141 of the holding structure 14 is close to the diameter of the shaft hole 313 to make the lever member 31 difficult to translate. The structure of the holding structure 14 is simple, convenient to manufacture, and easy to assemble with the lever member 31.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
