Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and drawings.

Please refer to FIG. 1 and FIG. 2 , the memory card connector 100 of the present invention includes a base 1 , a plurality of conductive terminals 2 accommodated inside the base 1 , and an upper cover 3 buckled on the base 1 . The base 1 has a base plate 11. The front and rear ends of the base plate 11 extend upwards to form a front wall 12 and a rear wall 13 respectively. A row of terminal slots 15 are respectively provided at the front and rear ends of the upper surface of the substrate 11 to accommodate corresponding conductive terminals 2. One end of the conductive terminal 2 protrudes upwards out of the card receiving space to form an arc-shaped elastic contact portion 21, and the other end is along the The terminal socket 15 extends out of one end of the base 1 and is electrically connected to a circuit board (not shown in the figure). According to the difference in the shape and structure of the memory card, each type of card uses one row of conductive terminals 2 therein. Wherein, a row of eight conductive terminals 2 close to the front wall 12 on the substrate 11 are Micro SD memory card terminals 16; a row of ten conductive terminals 2 close to the rear wall 13 are MMC Micro memory card terminals 17. Please refer to FIG. 4 and FIG. 5 , the inner surface of the front wall 12 is recessed to form a first engagement groove 121 extending transversely, so that the first abutment wall 122 and the second abutment wall are respectively formed on both sides of the first engagement groove. wall 123, and a notch 124 is also provided in part of the front wall 12, through which the memory card placed in the card accommodating space can be easily turned up and taken out. The inner surface of one side wall 14 is recessed to form a second engaging groove 141, which extends backward from the first abutting wall, and forms a third abutting wall 142 on its rear side. The abutting wall 142 is connected with the bottom wall 143 of the second engaging groove 141 in an arc shape, which conforms to the shape of the corresponding memory card.

Please refer to FIG. 3 , the upper cover 3 is formed by punching metal materials, of course, the upper cover 3 can also be formed by other materials and methods. The upper cover 3 includes a top plate 31 and two locking plates 32 extending downward from both sides of the top plate 31. Two approximately rectangular openings 311 are formed on the top plate 31. The top plate 31 extends from the two ends of each opening 311 to form A pair of elastic arms 331, the ends of the two elastic arms 331 are respectively bent downwards and extend towards each other to form a pair of inclined arms 332, the ends of the two inclined arms 332 are bent upwards and joined together to form a base 333, finally on the top plate 31 Each opening 311 of each opening 311 forms an elastic pressing piece 33 composed of two elastic arms 331 , two inclined arms 332 and a base 333 .

Referring to Fig. 4 and Fig. 6, when the Micro SD memory card 4 is to be assembled in the memory card connector 100, first, the Micro SD memory card 4 is placed in the card receiving space of the base 1, and its rear end abuts against the The rear wall 13, the front end is accommodated in the first engaging groove 121 and abuts against the inner wall of the first engaging groove 121, so that the Micro SD memory card 4 is fixed vertically; The sides are also laterally fixed by the first engaging grooves 121 . In addition, the signal conduction area (not shown) at the bottom of the Micro SD memory card 4 is in electrical contact with the terminal 16 of the Micro SD memory card. Then, the upper cover 3 in the opened state is buckled on the base 1. Since the thickness of the Micro SD memory card 4 is smaller than that of the MMC Micro memory card 5, the general upper cover cannot be used to form an effective resistance to it, so When the Micro SD memory card 4 is placed in the card receiving space, it will be displaced by the one-way thrust of the conductive terminal 2, and even cause poor conduction between the conductive terminal 2 and the memory card. Therefore, the Micro SD memory card 4 is elastically pushed up by the structure such as the elastic pressing piece 33 added to the upper cover 3, so as to ensure the stable conduction between the conductive terminal 2 and the Micro SD memory card 4.

Referring to Fig. 5 and Fig. 6, when the MMC Micro memory card 5 is to be assembled in the memory card connector 100, at first, the MMC Micro memory card 5 is placed in the card receiving space of the base 1, and its rear end abuts against the The rear wall 13, the front end abuts against the first abutting wall 122 and the second abutting wall 123 of the front wall 12, so that the MMC Micro memory card 5 is longitudinally fixed; the two sides of the MMC Micro memory card 5 are respectively abutted against the two The side wall 14, and the shape of one side of the MMC Micro memory card 5 coincides with the second engaging groove 141, so that the MMC Micro memory card 5 is laterally fixed. In addition, the signal conduction area (not shown) at the bottom of the MMC Micro memory card 5 is in electrical contact with the terminal 17 of the MMC Micro memory card. Then, the upper cover 3 in the opened state is fastened on the base 1, and the MMC Micro memory card 5 is elastically pressed against the MMC Micro memory card 5 through the structure such as the elastic pressing piece 33 added to the upper cover 3, so as to ensure that the conductive terminal 2 is in contact with the MMC Micro. The memory card 5 is turned on stably.

As mentioned above, the memory card connector 100 of the present utility model can firmly accommodate two kinds of memory cards of different specifications by adjusting the structure of the card receiving space and adding the elastic pressing piece 33 on the upper cover 3, so that the memory cards can be connected The device 100 is compact in size, simple in structure, and easy to operate, meeting today's demand for miniaturization of digital products.
