The insulating body 21 is made of plastic insulating material, and has a base portion 211 and two arm portions 212 connected to two ends of the base portion 211 extending in parallel. A card insertion space 22 is formed between the base portion 211 and the two arm portions 212 for use in To insert the memory card 30 .

The terminals 23 are installed on the base portion 211 of the insulating body 21 and extend parallel to the two arm portions 212 . The ends of the terminals 23 protrude from the insulating body 21 and are soldered to the circuit board 10 to be electrically connected to the circuit board 10 .

The shielding shell 24 is made of metal material and assembled on the front end of the insulating body 21 to prevent electromagnetic interference. The shielding shell 24 has a top plate 241 disposed between the two arm portions 212 near the front end.

The memory card 30 is a CF (COMPACT FLASH) card in the present embodiment, and the memory card 30 has a first end face 31, a second end face 32 and two side faces 33, and the second end face 32 and the first end face 31 are respectively located at The front side and the rear side of the memory card 30 , and two ends of the two side surfaces 33 are respectively connected to the second end surface 32 and the first end surface 31 . The first end surface 31 is also recessed with a plurality of insertion holes 311 for sleeved on the terminals 23 of the memory card connector 20 (please refer to FIG. 3 ).

The fixed cover structure 40 of the memory card is provided with a main body 41, and the two sides of the front end of the main body 41 are respectively provided with an L-shaped first holding portion 42, and the first holding portion 42 is formed by bending and extending downward from the main body 41, It includes a front piece 421 and a side piece 422 vertically connected to the front piece 421 . Two sides of the rear end of the main body 41 are respectively provided with a second holding portion 43 , and the second holding portion 43 is provided with a rear piece 431 (please refer to the second figure). The two first retaining portions 42 and the two second retaining portions 43 surround and form a card accommodating space 44 . The card accommodating space 44 is located at the bottom of the main body 41 for accommodating the memory card 30 .

A square convex body 45 protrudes upward from the top surface of the main body 41, and an accommodating space 451 is provided inside the convex body 45 (please refer to FIG. .

The top surface of the convex body 45 is pierced with a square slot 46, and the inner wall of the rear side of the slot 46 extends forward to form an elastic piece 47. The elastic piece 47 is located above the card space 44 and its end is a free end. Both sides of the terminal end of 47 are respectively bent upwards to form a protrusion 48 , and each protrusion 48 is provided with a slope 481 , and the slope 481 extends obliquely from the top of the protrusion 48 toward the fixed end of the elastic piece 47 .

The front end of the main body 41 extends forward to form an extension portion 49 for the user to hold. The bottom surface of the extension part 49 extends downwards near the front end to form a second blocking part 491 for contacting the memory card 30. The blocking part 491 includes a blocking piece 4911 and two side pieces 4912 (please refer to FIG. 2 ). The blocking piece 4911 is punched downwards from the main body 41 for abutting against the second end surface 32 of the memory card 30 . The two side pieces 4912 are formed by bending and extending forward from both sides of the blocking piece 4911 , and the tops of the two side pieces 4912 abut against the bottom surface of the extending portion 49 to increase the pushing force of the blocking piece 4911 .

When the fixed cover structure 40 of the memory card is installed on the memory card 30, the front piece 421 of the two first holding parts 42 and the blocking piece 4911 of the second blocking part 491 abut against the second side of the memory card 30. The end surface 32, the side pieces 422 of the two first holding parts 42 respectively abut against the two side surfaces 33 of the memory card 30, and the rear pieces 431 of the two second holding parts 43 abut against the first end surface 31 of the memory card 30 (Please refer to FIG. 1 ), so that the memory card 30 is held in the card space 44 .

Please refer to Fig. 4 and Fig. 5, when the memory card 30 is combined with the fixed cover structure 40 of the memory card and inserted into the card insertion space 22 of the memory card connector 20 (please refer to Fig. 3 for cooperation) The front edge of the top plate 241 of the shielding housing 24 of the memory card connector 20 will first abut against the slope 481 of the two convex parts 48, and at the same time press down the two convex parts 48. The two convex parts 48 rely on the elasticity of the elastic piece 47 and the guidance of the two inclined surfaces 481 to gradually displace downwards, and be accommodated in the accommodating space 451 of the protrusion 45, so that the two protrusions 48 can pass under the top plate 241 of the shielding housing 24, and allow The memory card 30 enters into the card insertion space 22 of the memory card connector 20, so that the jack 311 of the memory card 30 can be sleeved on the terminal 23 of the memory card connector 20 (please refer to FIG. 3 for cooperation) , to achieve electrical connection.

After the two protrusions 48 pass through the top plate 241 of the shielding housing 24, the two protrusions 48 can return to their original positions by virtue of the elasticity of the elastic piece 47 (please refer to FIG. 5 for cooperation). In this way, When the memory card 30 is intended to be loosened from the memory card connector 20 due to vibration or other reasons, the two protrusions 48 can be used to block the rear side of the top plate 241 of the shielding case 24 to prevent the memory card 30 from being released from the memory card connector 20. The memory card connector 20 comes loose.

When you want to take out the memory card 30 from the memory card connector 20, you only need to press down on the elastic piece 47, so that the two convex parts 48 are displaced downward to be accommodated in the accommodating space 451, and at the same time hold the extension The portion 49 pulls out the main body 41 together with the memory card 30 to disengage the memory card 30 from the memory card connector 20 .

Therefore, the fixed cover structure 40 of the memory card of the present invention is provided with an elastic piece 47 and two convex parts 48 on the main body 41, and the two convex parts 48 correspond to the shielding shell 24 of the memory card connector 20, and can be The elasticity of the shrapnel 47 displaces, and when the memory card 30 equipped with the fixed cover structure 40 is inserted into the memory card connector 20, the two protrusions 48 can be used to limit the memory card 30 on the memory card. The memory card 30 is prevented from being released from the memory card connector 20 in the connector 20 .

In addition, since the extension portion 49 has a considerable area, it is convenient for the user to hold and apply force, so that the extraction of the memory card 30 is more convenient and labor-saving.

But the above description is only the preferred feasible embodiment of the present utility model, and therefore does not limit the scope of protection of the present utility model. Therefore, all equivalent structural changes made by using the description of the utility model and the contents of the accompanying drawings are all the same. Included within the protection scope of the present utility model, it is hereby explained.
