The housing 11 includes a base 12 and a lid 18. The lid 18 covers the base 12, has an insertion port 14 at the front end, and has an insertion space 16 inside.

  The two movable hooks 21 have an elongated shape, and are disposed in the base 12 of the housing 11 so that one end is located on both sides of the insertion port 14. The movable hook 21 has a guide block 22 and a stopper 24 on one side facing the inside of the base 12 on the other end, and has a locking groove 26 between the guide block 22 and the stopper 24. The guide block 22 has a working surface 221 that is gradually inclined backward and rearward at the front end. The movable hook 21 is rotated about the one end having the guide block 22 around one end where the guide block 22 is not disposed, so that the movable hook 21 can be moved forward or backward with respect to the insertion space 16. The movable hook 21 maintains a state of being advanced into the insertion space 16 by the restoring unit 19. In the present embodiment, the restoring unit 19 is an elastic piece that is separately formed on both sides of the lid 18 of the housing 11 and that acts separately on the movable hook 21.

  The movable separator 31 is positioned in the insertion space 16 so as to be movable up and down, and divides the insertion space 16 into two upper and lower spaces. The movable separator 31 has working arms 32 that extend forward on both sides separately. The action arm 32 has a guide slope 34 and an action part 36 that extend forward and downward, and the action part 36 enters the locking groove 26 or keeps stationary according to the operation of the movable hook 21. The movable separator 31 has a plurality of hollow portions 38. The two movable hooks 21 are positioned on both sides of the movable separator 31 and abut against the action arm 32 of the movable separator 31 by the action of the restoring unit 19.

  The two terminal sets 41 and 51 are arranged on the base 12 of the housing 11 so as to enter the insertion space 16, and the first terminal set 41 is positioned below, has a plurality of first terminals 42, The two-terminal set 51 is positioned upward and has a plurality of second terminals 52. The second terminal 52 is fitted into the terminal block 54 and is disposed on the base 12 of the housing 11 via the terminal block 54. A part of the terminals of the second terminal 52 is partially positioned in the hollow portion 38 of the movable separator 31 and partially protrudes above the movable separator 31. A part of the second terminal 52 is fitted into the movable separator 31.

  The present embodiment further includes two auxiliary springs 61. The auxiliary springs 61 are arranged on both sides in the housing 11 so as to be positioned below the movable separator 31 and support the movable separator 31 in the upper position by restoring elasticity.

  In the present embodiment, the upper space of the movable separator 31 can be used for insertion of an SD card, an MMC (registered trademark) card, or an MMC Plus (registered trademark) card, for example. The space below the movable separator 31 can be used, for example, for insertion of an MS-Duo (registered trademark) card or an MS PRO-HG Duo (registered trademark) card.

Hereinafter, description will be given of the operation state of the present invention.
Before the memory card is inserted, the movable separator 31 is maintained at the upper position by the elasticity of the second terminal set, and the two auxiliary springs 61 support the movable separator 31 and bring the movable separator 31 to the upper position. maintain. The state in which the movable separator 31 is positioned above is as shown in FIG.

3 to 8 are schematic views showing the process of inserting the SD card.
As shown in FIG. 2, when inserting the SD card 91 from the insertion slot 14, if the SD card 91 is inserted from a position below the insertion slot 14, the SD card 91 is blocked by the shape of the insertion slot 14. Since this is not possible, it must be inserted from above the insertion port 14. As shown in FIGS. 3 and 4, in the insertion process, both sides of the SD card 91 act on the action surfaces 221 of the two movable hooks 21, push both sides of the two movable hooks 21, and stop 24 on the movable hook 21. And the action part 36 of the movable separator 31 is deviated.

  Subsequently, as shown in FIGS. 5 and 6, if the SD card 91 is continuously inserted, the bottoms on both sides act on the guide slopes 34 of the action arms 32 on both sides of the movable separator 31. At this time, since the stopper 24 (shown in FIG. 4) is separated from the action portion 36, the movable separator 31 is not limited and can move downward. Subsequently, as shown in FIG. 7 and FIG. 8, after the SD card 91 is completely inserted, it can be used by connecting to the second terminal set 51. When the SD card 91 is extracted, the SD card 91 is deviated from the movable separator 31 against the above-described process, the movable separator 31 is raised, and then the SD card 91 is continuously retracted, so that the two movable hooks 21 are moved. To deviate from. At this time, the restoring unit 19 acts on the two movable hooks 21 to advance the two movable hooks 21 into the insertion space 16 and abut against the movable separator 31. The two action portions 36 of the movable separator 31 are fitted in the locking grooves 26 of the two movable hooks 21.

  As shown in FIG. 9, when another memory card such as the MS-Duo card 92 is to be inserted from below after the SD card 91 is completely inserted, the movable separator 31 prevents the memory card from being inserted.

Hereinafter, the process of inserting a memory card (for example, an MS-Duo card) from below the movable separator 31 will be described.
As shown in FIGS. 10 and 11, when the MS-Duo card 92 is inserted, it can be used by inserting and fixing the MS-Duo card 92 from below the movable movable plate 31 and connecting it to the first terminal set 41. Subsequently, as shown in FIG. 12, after the MS-Duo card 92 is inserted and fixed, the MS-Duo card 92 occupies the lower space, so that the movable movable plate 31 cannot move downward. At this time, if the SD card 91 is to be inserted from above the movable separator, the movable separator 31 cannot move downward, and the insertion of the SD card 91 is prevented. Therefore, this embodiment can achieve the function of inserting only one card by the movable separator 31.

  As shown in FIGS. 13 and 14, when the MS-Duo card 92 is to be inserted from above the movable separator 31, the action portions 36 (shown in FIG. 1) on both sides of the movable separator 31 are provided on the movable hook 21. Since it is blocked by the stopper 24 and cannot move downward, the movable separator 31 prevents the MS-Duo card 92 from being inserted. As shown in FIG. 15, when an MS-Duo card 92 is to be inserted from one side (for example, the right side) above the movable moving plate 31, the MS-Duo card 92 acts on one movable hook 21 and is movable. It is possible to release the blocking state on one side of the plate 31 and move the movable moving plate 31 downward, but the action part 36 on the other side of the movable moving plate 31 is blocked by the movable hook 21 and moves downward. Since this is not possible, the movable moving plate 31 cannot move downward and maintains the blocking function. Therefore, the MS-Duo card 92 cannot enter the space above the movable separator 31.

(Second Embodiment)
As shown in FIG. 16, the multi-memory card connector 70 according to the second embodiment of the present invention is substantially the same as the first embodiment. Differences from the first embodiment are as follows.
There is only one movable hook 75. Further, it is mounted on the left side in the housing 71 and acts only on the left acting part (not shown in the figure) of the movable separator 78.

Since the operation state of the second embodiment is the same as that of the first embodiment, the description thereof is omitted.
Although the second embodiment can achieve most of the effects of the first embodiment, it cannot achieve the effect of preventing erroneous insertion by only one side acting on the movable hook as shown in FIG.

  As described above, the present invention achieves an effect that only one card can be inserted by moving the movable moving plate 31 up and down and limiting the insertion space 16. The present invention has an effect of preventing erroneous insertion by locking or releasing the movable plate 31 that moves up and down via the two movable hooks 21. In other words, since the present invention can have both the function of inserting only one card and the function of preventing erroneous insertion by appropriately combining the motion state of the movable separator and the movable hook, the technical means Is different from the prior art.
