  Further, in the above description, the identification portion 11g is formed to extend from the overhang portion 11e. However, the identification portion 11g may be extended from the overhang portion 11d, and the second engagement piece 11f2 is formed in a flat plate shape. You may make it also serve as the identification part 11g.

  Moreover, this embodiment is provided with the notch part 11i in the insertion port side of the card | curd 1 of the metal frame 11 as shown in FIG. This is such that when the card 1 mounted in the housing 10 is pulled out of the housing 1, a finger can be placed on the card 1.

[Attaching a card to this embodiment]
6 is a plan view showing when the card is inserted into the present embodiment, FIG. 7 is a view showing a state where the card is mounted on the present embodiment, (a) a plan view, (b) a side view, (C) is a front view, (d) is a rear view, and FIG. 8 is a rear view showing a state in which a card is mounted in this embodiment.

  In order to mount the card 1 in this embodiment, as shown in FIG. 6, the back end 4 of the card 1 is inserted from the insertion port 10a of the housing 10, and the card 1 is pushed in the back direction. When the card 1 is pushed, the back end 4 of the card 1 is inserted into the relief 10c of the back end 10b of the housing 10, and the taper 4a of the back end 4 of the card 1 is shown in FIG. ) It is locked to the tapered stopper portion 10j of the housing 10 shown in the drawing, and the curved surface portion 4b of the back end 4 of the card 1 is locked to the curved stopper portion 10i of the housing 10.

  As described above, when the card 1 is inserted into the housing 10, both sides of the card 1 are guided to both sides 11 b and 11 c of the metal frame 11, and the notch 6 of the card 1 is provided with the housing 10. Guide part 10g.

  As shown in FIGS. 7 and 8, when the card 1 is mounted in the housing 10, the end surface 4 c of the back end 4 of the card 1 and the outer end surface 10 d of the back end 10 b of the housing 10 are on the same plane. Form. Further, the movement of the card 1 is regulated by the both side portions 11b and 11c, the bottom portion 11a, and the projecting portions 11d and 11e of the metal frame 11, and the first engagement with the concave portion 5 formed on the side portion of the card 1. The mating piece 11f1 is engaged, the second engaging piece 11f2 is positioned on the surface of the card 1, and the movement of the card 1 is also restricted by the first engaging piece 11f1 and the second engaging piece 11f2. .

  When inserting the housing 10 with the card 1 mounted into a card insertion slot of a connector device (not shown), for example, as indicated by an arrow 12 in FIG. Is supposed to be inserted.

[Operational effects of this embodiment]
According to the card adapter of this embodiment configured as described above, even when the depth dimension of the card 1 attached to the housing 10 is equal to the depth dimension of the card not shown that is directly attached to the connector device not shown. When the card 1 is mounted on the housing 10, the back end 4 of the card 1 is inserted into the relief 10c of the back end 10b of the housing 10, so that the movement of the card 1 is caused by the relief 10c. Can be regulated. As a result, the card 1 can be stably held in the housing 10, and an excellent card holding function can be secured.

  Further, when the card 1 is mounted on the housing 10, the taper portion 4 a and the curved surface portion 4 b of the card 1 are respectively engaged with the stopper portion 10 j and the stopper portion 10 i formed at the back end portion 10 b of the housing 10. Until the card 1 is inserted into the housing 10, the card 1 can be easily and accurately positioned with respect to the housing 10, and the card 1 can be easily mounted.

  Further, the card type attached to the connector device (not shown) can be identified by the connector device via the identification unit 11g. That is, when the housing 10 in which the card 1 is mounted is inserted into a connector device (not shown), the one inserted by the identification portion 11g formed in the metal frame 11 is the housing 10 into which the card 1 is inserted. It is identified by a connector device (not shown). In other words, depending on the presence or absence of the identification unit 11g, it is determined whether the card attached to the connector device is the card 1 attached to the housing 10 or another card directly attached to the connector device. The device can be identified. Thereby, it is possible to realize a specific signal processing for each different card mounted on the connector device, and an excellent information processing function can be secured.

  Moreover, since the identification part 11g is formed by the both sides 11b and 11c, or the bottom part 11a, which are a part of the metal frame 11, there is no need for a special member for forming the identification part 11g, and a simple configuration. This contributes to a reduction in production costs.

  Further, since the side portions 11b and 11c of the metal frame 11 can be interposed between the card 1 and the resin housing 10, the side portion of the card 1 and the side portion of the housing 10 are not in contact with each other. When the card 1 is mounted on the housing 10 to be performed, there is no possibility that the housing 10 will sag due to the contact of the card 1. Therefore, there is no gap in the side portion of the card 1 over a long period. Further, the movement of the card 1 mounted in the housing 10 is restricted by the side portions 11b and 11c, the bottom portion 11a, and the projecting portions 11d and 11e of the metal frame 11, and the movement is also performed by the engaging portion 11f. Be regulated. As a result, the card 1 can be prevented from falling off the housing 10 over a long period of time, and the card 1 can be stably held in the housing 10 to ensure excellent durability.

  Further, the engaging portion 11f including the first engaging piece 11f1 and the second engaging piece 11f2 is also provided with a special member in the same manner as the both side portions 11b and 11c of the metal frame 11 or the overhanging portions 11d and 11e. And can be easily provided by a part of the metal frame 11, which contributes to a reduction in production costs.

  Further, the card 1 mounted in the housing 10 is restricted from moving in the width direction of the card 1 by both side portions 11b and 11c of the metal frame 11, and is restricted from moving in the card insertion / removal direction by the first engagement piece 11f1. Since the movement of the card 1 in the thickness direction is restricted by the bottom 11a, the overhanging portions 11d and 11e of the metal member 11, and the second engagement piece 11f2, the card 1 can be more securely held stably in the housing 10. Can do.

  In addition, a part of the metal frame 11 at a predetermined portion of the metal frame 11 can be divided into upper and lower parts to easily provide the first engagement piece 11f1 and the second engagement piece 11f2. The installation space for the first engagement piece 11f1 and the second engagement piece 11f2 can be reduced.

  Further, since the housing 10 has side walls 10e and 10f on the outer sides of both side portions 11b and 11c of the metal frame 11, the width dimension of the housing 10 can be set by appropriately setting the shapes of the side walls 10e and 10f. Can be easily set to a width dimension suitable for a card insertion portion of a connector device (not shown).

  Moreover, since the connection part which consists of the back side edge part 10b which connects both the side walls 10e and 10f of the housing 10 is provided, the bending deformation of the metal frame 11 can be suppressed by this back side edge part 10b, and metal The original shape of the frame 11 can be maintained over a long period of time.

  Moreover, since the connection part which connects the both side walls 10e and 10f of the housing 10 is comprised by the back | inner side edge part 10b which is a part of the housing 10, a connection part can be formed without providing a special member, and simple. This also contributes to a reduction in production costs.

  Further, when the card 1 mounted on the housing 10 is pulled out, the card 1 can be easily pulled out by inserting a finger into the cutout portion 11i of the metal frame 11, which is easy to use.

  Further, when the card 1 is inserted into the housing 10, the card 1 comes into contact with the resin portion 10h, so that the card 1 can be smoothly inserted, and the card 1 accompanying the repeated mounting of the card 1 into the housing 10 is realized. Wear and tear can be suppressed. Moreover, the resin part 10h can prevent the card 1 and the metal frame 11 from being short-circuited.
