Become.

  When the card 1 is taken out, the convex portion 11c of the terminal member 11 is detached from the concave portions 1f and 1g of the card 1 by grasping and pulling out the front portion protruding from the insertion port 15 shown in FIG. The card 1 can be taken out.

[If the card is inserted incorrectly with the front and back reversed]
FIG. 6 is a view showing a state in which the card is inserted into the embodiment in the front-rear direction, where (a) is a plan view, (b) is a left side view, (c) is a right side view, d) The figure is a back view.

  As shown in FIG. 6, when the card 1 is inserted with the front and rear direction reversed, the rear end portion 1c of the card 1 comes into contact with the erroneous insertion preventing members 16 and 17 and is prevented from moving. The That is, it is understood that the insertion is wrong at the moment of insertion into the insertion port 15.

[If the card is inserted incorrectly with the front and back reversed]
FIGS. 7A and 7B are views showing a state in which the card is erroneously inserted into the front and back in this embodiment, where FIG. 7A is a plan view and FIG. 7B is a right side view.

  As shown in FIG. 7, when the card 1 is erroneously inserted upside down, it is the same as described above, and the portion other than the taper portion 1a of the front end portion 1a of the card 1 is an erroneous insertion preventing member. 16 and 17 are prevented from moving. Also at this time, it is understood that the insertion is wrong at the moment of insertion into the insertion port 15.

[Effect of this embodiment]
As described above, in the present embodiment, the metal thin plate 4 is integrally provided on the back surface of the housing 2, and thus the metal thin plate 4 can ensure rigidity, that is, a desired strength. Thereby, the housing 2 can be formed thin, and the overall thickness of the apparatus can be reduced in accordance with the reduction in the thickness of the inserted card 1.

  Further, since the metal thin plate 4 is provided integrally with the housing 2 by insert molding, the metal thin plate 4 can be easily provided on the back surface of the housing 2.

  Further, since the metal thin plate 4 to be grounded is disposed around the terminal member 3, noise countermeasures can be enhanced.

  Also, by soldering to a circuit board (not shown) via a soldering portion 5 formed on the metal thin plate 4, mounting on the circuit board is easy.

  Furthermore, the upper and lower sides of the inserted card 1 can be covered with the metal thin plate 4 and the cover member 10 which are grounded, and noise countermeasures can be further strengthened.

  Further, in this embodiment, the elastic member 11 having the convex portions 11c that engage with the concave portions 1f and 1g of the card 1 forms a part of the cover member 10, so that the card 1 is not increased without increasing the number of parts. It can be held in a mounted state, and can be easily handled during production, and production costs can be reduced.

  Further, since the elastic member 1 is formed in a cantilever shape and is disposed so as to be engaged with the concave portions 1f and 1g of the card 1 from the side of the card 1, even if the card 1 is a thin card, the concave portion 1f. , 1g can be formed deeply, and the card 1 can be securely held in the mounted state by engaging the elastic member 11 with the concave portions 1f, 1g from the side.

  Further, the elastic member 11 is provided at a symmetrical position on both right and left side portions, and the convex portion 11c of the elastic member 11 is engaged with each of the concave portions 1f and 1g of the card 1 at the left and right symmetrical positions, so that the card 1 is not inclined. The card 1 can be regulated and can be held in a stable mounting state.

  Moreover, since the guide part 11a which guides the card | curd 1 is formed in the card insertion side part of the elastic member 11, the card | curd 1 can be smoothly inserted through this guide part 11a.

  Moreover, since each base part 11b of the elastic member 11 is pressed down by the press-fitting parts 12 and 13, deformation | transformation of each base part 11b of the elastic member 11 can be suppressed, and the elastic force of these elastic members 11 can be strengthened. .

  Further, since the openings 12a and 13a are formed in the upper portions of the press-fitting portions 12 and 13, the cover member 1 can be easily moved from above the housing 2 through the openings 12a and 13a of the press-fitting portions 12 and 13. Can be attached to.

  In addition, since the present embodiment includes the erroneous insertion preventing members 16 and 17 in the vicinity of the insertion slot 15, when the card 1 is erroneously inserted, the erroneous insertion is provided in the vicinity of the insertion slot 15. The movement is prevented by the preventing members 16 and 17, and it can be seen that the card 1 is erroneously inserted immediately after the card 1 is inserted into the insertion slot 15, and the usability can be improved.

  Further, when the card 1 is correctly inserted, each of the erroneous insertion preventing members 16 and 17 does not engage with the card 1, and when the card 1 is erroneously inserted, a pair provided in the vicinity of both the left and right side portions. The erroneous insertion prevention members 16 and 17 can reliably prevent the card 1 from moving.

  Further, since the erroneous insertion preventing members 16 and 17 form a part of the cover member 10, the number of parts is not increased and the production cost is reduced.

  Further, since the erroneous insertion preventing members 16 and 17 are disposed closer to the insertion port 15 than the elastic member 11, the erroneously inserted card 1 hits the erroneous insertion preventing members 16 and 17, but the elasticity of the erroneously inserted card 1 is increased. The deformation of the member 11 can be prevented.
