Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3A, Fig. 3B, the improved structure of the memory card electrical connector of the present invention includes an insulating shell 10, a plurality of terminals 30 and two hooks 50, and the insulating shell 10 includes a center with a center Slot 11 and the plurality of terminal grooves 12 that both sides communicate with this central slot 11, this central slot 11 is provided for the insertion of a memory card 100 (as shown in Figure 4 A), the two ends of this insulating housing 10 A hook seat 13 is provided. The hook seat 13 includes side seats 14 on both sides and a column seat 15 at the rear end. The inner surface of the side seat 14 is provided with longitudinally protruding abutment strips 16 and longitudinally indented abutment grooves. 17 (as shown in Figure 3A), the two side seats 14 are also bent towards the front end to form a Y-shaped missing groove 18, and the missing groove 18 communicates with the central slot 11. There is a longitudinal slot 19 and a pivot slot 21 below the slot 19 ; the terminals 30 are set in the terminal slots 12 of the insulating housing 10 , and are used to conduct electrical signals with the memory card 100 .

The hook 50 is pivotally arranged in the hook seat 13 of the insulating housing 10, and includes a push part 51 integrally formed at the top, side walls 52 and side walls extending downward from both sides of the push part 51. 52, the bottom edge of the butt plate 53, the pushing part 51 is provided with a top wall 54 and a ㄇ-shaped chamber space 54A below the top wall 54 on the side opposite to the central slot 11, and the chamber space 54A extends forward Two clamping blocks 55 are protrudingly provided, and there is a gap 56 between the clamping blocks 55 (as shown in Figure 2 and Figure 6B), and there is a distance 57 between the clamping block 55 and the side wall 52, so that the The clamping block 55 is a free-end elastic clamping rod body. In addition, the front end of the clamping block 55 is further provided with a guiding slope 58 for auxiliary insertion; There is a side clamping block 59, and a gap 61 is formed between the side clamping blocks 59, and the distance of the gap 61 is greater than the distance of the gap 56 (as shown in FIG. 6B ). Pivot groove 21 protrudes with a pivot rod 62, and the bottom edge of the front end of the pivot rod 62 is provided with a guide inclined surface 63 (as shown in Fig. 3A and Fig. 6B) to facilitate sliding and pivoting along the socket 19 of the post base 15. In the pivot groove 21, the hook 50 is pivotally connected to the hook seat 13, and can be rotated. The outer side of the side wall 52 is further protruded with a block 64, and the block 64 is slightly in shape. Triangular pyramid bar, when the hook 50 is pulled from the outside to the inside, the abutting block 64 will pass over the abutting bar 16 of the side seat 14 and be stuck in the abutting groove 17, so as to form the buckled state of the hook 50 ; And the front end of the abutting plate 53 is protruded with a abutting end 65 to facilitate the abutting operation of taking out the memory card 100 .

As shown in Fig. 4A, Fig. 4B, Fig. 4C and Fig. 5A, Fig. 5B, when the memory card 100 is about to be inserted into the central slot 11 of the insulative housing 10, the hook 50 is first in an everted position. The insertion of the memory card 100 will make the bottom of the memory card 100 contact the abutment 65 and the abutment plate 53, and make the hook 50 turn inwards with the force applied by the card, and when the memory card 100 is inserted into the position At this time, the top wall 54 of the hook 50 just fits into a positioning groove 101 on the side of the memory card 100 to position the memory card 100 .

And when the hook 50 is relatively close to the memory card 100 with the action of inserting the card, the clip block 55 first guides the memory card 100 into the gap 56 through its guide slope 58, and because the clip block 55 It has elasticity, so when the memory card 100 is slightly skewed or its thickness dimension has a positive or negative deviation, it is still very easy to insert the memory card 100; and when the memory card 100 is inserted to the position or the hook 50 pushes the memory card 100 to the position by means of its top wall 54, the abutting piece 64 of the hook 50 is just positioned in the abutting groove 17 of the hook seat 13 (as shown in Figure 6A), and the memory card 100, the embedded clamp is positioned in the gap 56 between the clamp blocks 55, so that when the thickness of the memory card 100 has a positive or negative deviation, it can still be guided and fixed, so as to prevent the product from being damaged due to vibration during transportation. This causes the memory card to loosen, thereby ensuring the quality of product assembly and operation.

Furthermore, the memory card 100 is ejected by pulling the pushing part 51 of the hook 50, so that the abutting end 65 and the abutting plate 53 of the hook 50 are rotated to push out the memory card 100 (as shown in FIG. 7), and because the setting of the elastic clip block 55 of the present invention does not have a lack of tight fit with the memory card 100, it can further avoid the phenomenon that the memory card 100 is difficult to withdraw from the card.

In summary, the utility model "improved structure of memory card electrical connector" can indeed meet the requirements of the original utility model through its unique structural features, and no similar structure has been published before and meets the requirements of the patent , Yuan filed a patent application in accordance with the law, and I sincerely hope that this application will be approved as soon as possible, so as to demonstrate the legislative spirit of the Patent Law to reward Chinese people for utility models, which is what I look forward to.
