[Embodiment] Please refer to the drawings for the detailed description of the preferred embodiment, and please refer to Figure 丨 _7 first. The present invention uses a memory card connector (Figure 17_19) for approximately 22 An adapter of approximately 20 and 20 is taken as an example, and the memory card connector 22 has a socket 24 for receiving a standard memory card (larger card) of a larger size and approximately 26. This can be molded from a plastic material. Please refer to FIG. 1_7 again. The adapter 20 includes an insulated housing generally shown, and the housing 28 has a size 200521873 and a shape substantially the same as the larger card%, as shown in FIG. 17. . The housing has a substantially flat storage area 30, and the storage area 30 is shallow and includes a bottom 30a, a pair of side walls 30b, an open end 30c, and a closed end 30d. This storage area accommodates a standard memory card of a smaller size ("smaller card,"), generally represented by 32 (Figure 8_12 5), and the smaller card is inserted into the storage unit in the direction of the arrow "D" In the region 30. A semicircular coupling recess 34 is formed at one side of the storage region, and a coupling protrusion 36 is formed at the opposite side of the storage region. The guide arm 38 is at the open end 30c of the storage region. The adaptor 20 is gripped by an operator at the gripping end 4010 of the casing 28. Also, to facilitate the gripping of the casing, a shallow area 40a is formed at the grip The top of the end 40, and a deeper area 40b is formed at the bottom of the gripping end. A clamping member indicated generally at 42 is mounted on the housing 28 to hold a smaller card 32 in the case. In the body receiving area 30, and the clamping member is made of an elastic metal material and is installed in the mounting section 44 of the housing 28. The clamping structure 15 piece 42 is substantially L-shaped and includes one forming a clamping Part 42a and the first leg part of the three fixing parts or leg parts 42b, and these fixing parts 42b are substantially formed with the clamping part or leg part 42a Angularly extending. The clamping portion 42a is substantially flat and has a width equal to the width "W1" of the storage area 30, and the clamping portion extends forward from the fixing portion 42b into the storage area 30. A pair of side elastic walls 42c It is integrally formed with the clamping portion 42a at the opposite side edge of the 20 and extends from the clamping portion 42a at a right angle. The fixing portion 42b is press-fitted into three narrow portions fitted in the mounting section 44 of the casing. Hole 46, and the clamping portion has an integral reinforcing rib 42d. The bottom 30a of the storage area 30 is inclined downward from the open end 30c toward the closed end 30d, so that the smaller card 32 is inserted into the storage area and inserted Below the clamping portion 42a of the clamping member 42 200521873. In addition, when the smaller card is inserted into the adapter, the inclination of the bottom 30a prevents the top surface 42d of the clamping portion 42a from protruding from the side wall 30b of the storage area. Above. Finally, a recessed portion 48 is formed in the bottom portion 30a and spans the width of the bottom portion. 5 Refer to Figure 8_12. The smaller size standard memory card is generally rectangular and has a width approximately equal to that of the adapter 20. The width of the storage area 30 in the case 28 "W1" (Fig. 1) "W2" (Figure 8). The smaller card has a top surface 50 and a bottom surface 52, and most of the contact pads 54 are arranged in a parallel array in the bottom surface 52 before the smaller card. A combination recess 56 A semicircular coupling recess 58 formed on one side of the 10 card is formed on the opposite side of the card. Another guide groove 60 for receiving the guide arm 38 is provided at the trailing edge of the card outside the contact pad 54. Figures 13 and 14 show the small card 32 inserted into the storage area 30 of the housing 28 appropriately to form a memory card module indicated generally at 62, where the smaller card can be seen at 15 Below the clamping portion 42a of the spring-biased clamping member 42. The contact pad 54 of the memory card is exposed at the opening end 30c of the storage area 30. Figures 15 (a) -15 (c) show that the smaller card 32 is inserted obliquely into the storage area 30 of the adapter 20 in the direction of the arrow "E", and the front end of the smaller card 20 is inserted into the bottom of the storage area. 30a is inserted below the clamping portion 42a of the clamping member 42. The leading edge of the smaller card is inserted below the clamping portion in the direction of the arrow “F”, and the trailing edge of the smaller card is pivoted downward in the direction of the arrow “F”, as shown in FIG. 15 (c) . Once fully inserted, the smaller card 32 is positioned within the storage area 30 as previously described with reference to Figures 13 and 14. The clamping portion 42a of the elastic metal 11 200521873 clamping member 42 holds the smaller card downward on the bottom portion 30a in the storage area 30. The coupling protrusions 36 (Figure 1) in the storage area 30 of the housing 28 are combined with each other in the coupling recess 56 (Figure 8) of the smaller card 32 to prevent the card from being pulled out of the storage area 30. 5 Figure 16 shows the smaller card 32 inserted into the adapter 20 in an incorrect orientation (eg, upside down). When so erroneously inserted, the coupling protrusion 36 prevents the memory card from being placed on the bottom 30a of the storage area, and this makes it easy for the operator to find that the orientation of the smaller card must be readjusted. FIG. 17 shows the $ 50 memory card module 62 including the adapter 20 and the smaller card 32 and the larger size 10 of the 5th memory card 26.
