The second conductive terminal 24 is connected to the conductive pad of the small-sized card 300, one end penetrates the bottom plate 14 and is soldered to the hand circuit board, and the other end extends to the accommodation space 18.

  The shield 28 includes a top plate 30 corresponding to the insulating housing 10, a bottom plate 32, and a side plate 34 connecting the top plate 30 and the bottom plate 32, and the top plate 30 has a separable separation plate 301. Have. The separation plate 301 is formed with a receiving space 302 formed so as to project upward, and a holding piece 303 formed so as to protrude from the top wall of the separation plate 301 toward the receiving space 302. A spring 304 is accommodated in the receiving space 302. One end of the spring 304 is held by the holding piece 303, and the other end is held by the erroneous insertion preventing mechanism 40.

  The top plate 30 is formed with an opening 36 communicating with the opening 13 of the insulating housing 10 and elastic pieces 37 disposed on both sides of the opening 36. It extends upward to engage with a projection 305 formed on the separation plate 31. A pressing piece 38 is formed on the side plate 34.

  Referring to FIGS. 6 to 9, the erroneous insertion preventing mechanism 40 is attached to the front side of the insulating housing 10 and covers a large card insertion slot 19 as a shutter. 44 includes pivot shafts 42 on both sides of 44 and an insertion slot 46 formed in the main body 44 for inserting a small-sized card 300. The insertion port 46 communicates with the accommodation space 18 and overlaps the insertion port 19, and convex lumps 51 that abut against the elastic pieces 37 of the shield 28 are formed on both sides of the rear wall 50 of the main body 44. Is done.

  A pair of guide members 48 formed so as to extend from the rear wall 50 of the main portion 44 along the card insertion direction in order to guide the card 300 having a small size are provided. 46 on both sides. The guide member 48 is formed with a positioning portion 54 at the end, a guide groove 4811 for holding the spring 304 is formed in the top wall 481 near the top plate 12 of the insulating housing 10, and the bottom plate 14 of the insulating housing 10 is formed. A convex portion 4821 accommodated in the accommodation port 142 of the insulating housing 10 is formed on the adjacent bottom wall 482. An elastic acting force is applied to the guide member 48 by the spring 304. Further, in order to support the small card 300, a support plate 52 formed so as to extend from the rear wall 50 of the main portion 44 toward the accommodating space 18 is located below the insertion slot 46, It is accommodated in the recess 15 of the insulating housing 10.

  The shell 56 is made of a metal plate, and covers a spring 581 on shafts 58 formed on both sides. One end of the spring 581 is held by the main body 44 of the erroneous insertion preventing mechanism 40 and the other end is a shell. 56. Accordingly, the shell 56 is rotatably mounted on the rear wall 50 of the erroneous insertion preventing mechanism 40 and covers the insertion opening 46.

  The engaging member 60 is rotatably attached to the notch 17 formed at the tip of the side wall 16 and is pressed by the pressing piece 38 of the shield 28. The engaging member 60 has a pivotal support 62, a pressing surface 64 that comes into contact with a large-sized card, and an engaging portion 66 for locking the erroneous insertion preventing mechanism 40.

  When the card is not yet inserted, the erroneous insertion preventing mechanism 40 covers the insertion slot 19 of the large card, and the shell 56 attached to the erroneous insertion preventing mechanism 40 is inserted into the small card 300. Covers the entrance 46. When a large-sized card is inserted, when both side ends of the card abut against the pressing surface 64 of the engaging member 60, the engaging member 60 is rotated outwardly about the pivot portion 62. Accordingly, the engaging portion 66 for locking the erroneous insertion preventing mechanism 40 also rotates outward, so that the erroneous insertion preventing mechanism 40 and the engaging portion 66 are unlocked. The erroneous insertion prevention mechanism 40 rotates upward in accordance with insertion of a large card, and reaches the horizontal position through the opening 13 of the insulating housing 10 and the opening 36 of the shield 28. At this time, the large-sized card is electrically connected to the first conductive terminal 22, and the shell 56 is in a closed state covering the insertion slot 46 of the small-sized card 300.

  When a large card is ejected, one end of the spring 304 attached to the separation plate 301 of the shield 28 comes into contact with the guide member 48 of the erroneous insertion preventing mechanism 40, and the elastic piece 37 of the shield 28 is erroneously inserted. The pressing piece 38 is pressed against the engaging member 60 by coming into contact with the convex block 51 of the preventing mechanism 40, thereby recovering the erroneous insertion preventing mechanism 40 and the engaging member 60 to the initial state.

  Referring to FIG. 10, when the small card 300 is inserted into the insertion slot 46, the lateral width is small so that it does not come into contact with the engagement member 60, and immediately presses the shell 56 and rotates it upward. The guide member 48 and the support plate 52 are accommodated and supported in the accommodation space 18 to achieve electrical connection with the second conductive terminal 24. When the small card 300 is discharged, the shell 56 is restored to the initial state by the elastic force of the spring 581.

  When the insertion force of the small-sized card 300 is too large, the guide member 48 is restricted from moving in the front and left and right directions by the convex mass 4821 being accommodated in the accommodation port 142 of the insulating housing 10, and further It is ensured to guide the insertion of small cards.

  Although the present invention has been described in detail with reference to the preferred embodiments, the embodiments are merely illustrative and are not limited thereto. Further, any modification or change in details that can be made based on the present invention falls within the scope of the claims of the present invention.
