  As shown in FIG. 7, the internal space surrounded by the side surface portions 103a and 103b and the back surface portion 103c of the housing 104 is an insertion space for the first card 10, the second card 20, the third card 30 and the fourth card 40. (Mounting region) is formed, and a first contact terminal group 111, a second contact terminal group 112, a third contact terminal group 113, and a fourth contact formed of a conductive member are formed on the inner bottom surface portion. A terminal group 114 is sequentially arranged from the insertion slot 102.

  FIG. 8 is a perspective view showing the first contact terminal group 111, the second contact terminal group 112, the third contact terminal group 113, and the fourth contact terminal group 114, and FIG. 9 is a side view thereof. As shown in FIGS. 6 to 9, the first contact terminal group 111 includes a plurality of contact terminals 111 a arranged along the insertion slot 102. Each contact terminal 111a is formed with a curved portion 111b that is curved toward the card insertion space in the housing 104 (upward in FIGS. 8 and 9). The curved portion 111b has the first card 10 inserted therein. In this case, a contact portion (first contact portion) that contacts the contact terminal 11a (FIG. 2) of the first card 10 is formed.

  The second contact terminal group 112 has a plurality of contact terminals 112 a arranged along the insertion slot 102. Each contact terminal 112a is formed with a curved portion 112b curved toward the card insertion space in the housing 104. The curved portion 112b is in contact with the second card 20 when the second card 20 is inserted. The contact part (2nd contact part) which contacts the terminal 22a (FIG. 3) is comprised.

  The third contact terminal group 113 includes a plurality of contact terminals 113 a arranged along the insertion slot 102. Each contact terminal 113a is formed with a curved portion 113b which is curved toward the card insertion space in the housing 104, and this curved portion 113b is formed on the second card 20 when the second card 20 is inserted. The contact part (3rd contact part) which contacts the contact terminal 21a (FIG. 3) is comprised. The curved portion 113b of the contact terminal group 113a is also in contact with the contact terminal 31a (FIG. 4) of the third card 30 when the third card 30 is inserted.

  The fourth contact terminal group 114 (FIG. 7) has a plurality of contact terminals 114 a arranged along the insertion slot 102. Each contact terminal 114 a is formed with a curved portion 114 b that is curved toward the card insertion space in the housing 104, and this curved portion 114 b is formed on the fourth card 40 when the fourth card 40 is inserted. The contact part (4th contact part) which contacts the contact terminal 41a (FIG. 5) is comprised.

  In the present embodiment, the curved portion 111b of each contact terminal 111a of the first contact terminal group 111 and the curved portion 112b of each contact terminal 112b of the second contact terminal group 112 depend on the type of card to be inserted. Therefore, it is necessary to arrange them at close positions. Accordingly, each contact terminal 111a of the first contact terminal group 111 and each contact terminal 112a of the second contact terminal group 112 are cantilevered in opposite directions.

  That is, each contact terminal 111a of the first contact terminal group 111 is separated from the bottom surface portion 105 of the housing 104 with the front end portion 111c (free end) facing the back side of the card insertion space on the card insertion slot 102 side. On the other hand, each contact terminal 112a of the second contact terminal group 112 is in a state where the front end 112c (free end) faces the insertion port 102 side on the back side of the card insertion space. Cantilevered on the bottom portion 105.

  As shown in FIGS. 6 and 7, a cam plate 130 is provided in the inner space of the housing 104 as a push-down member that pushes the contact terminals 112a of the second contact terminal group 112 outward in the card insertion space. . The cam plate 130 is pivotally supported by the housing 104 via pivot shafts 131 and 132. That is, the cam plate 130 is pivotally supported in a state where the rotation shafts 131 and 132 are arranged on the card insertion slot 102 side, and is provided so that the rotation end 130a faces the back side of the card insertion space. The rotation shafts 131 and 132 are provided on both sides of the first contact terminal 111a extending in the card mounting direction, so that the cam plate 130 can rotate stably.

  As shown in FIGS. 10 and 11, the cam plate 130 has a plurality of openings 133. The opening 133 is formed to a size that allows the curved portion 111b of each contact terminal 111a constituting the first contact terminal group 111 to be inserted.

  That is, since the opening 133 is formed in a larger shape than the curved portion 111b of the contact terminal 111a, the curved portion 111b of the contact terminal 111a is inserted into the opening 133 as shown in FIGS. In this state, even when the cam plate 130 rotates in the direction of the arrow a about the rotation shafts 131 and 132, the cam plate 130 and the curved portion 111b of the contact terminal 111a and the tip end portion 111c interfere with each other. It is made not to do. Thus, even when a card is inserted from the insertion slot 102 and the cam plate 130 is rotated in the direction of arrow a by this card, the contact terminal 111a is not contacted with the contact terminal 111a. Thus, a constant state is maintained without receiving interference from the rotating operation of the cam plate 130.

  An extension portion 134 is extended on the rotating end side of the cam plate 130, and an opening (through hole) 135 is formed in the extension portion 134. The opening 135 is formed in such a size that the portion protruding to the card insertion space side of the curved portion 112b of the contact terminal 112a constituting the second contact terminal group 112 can be inserted. One end portion 135a on the side of the mouth 102 is configured such that the tip end portion 112c of the contact terminal 112a abuts inward from the outside of the card insertion space. In this case, the tip 112c of the contact terminal 112a abuts on the end 135a of the opening 135 with a force corresponding to the elastic force of the contact terminal 112a itself.

  As a result, when a card is inserted from the insertion slot 102 and the cam plate 130 is rotated by this card in the direction of arrow a (the direction from the inside to the outside of the card insertion space), the end portion 135a of the opening 135 is provided. The tip end portion 112c of the contact terminal 112a that is in contact with is pushed down in the direction of arrow a by the end portion 135a. That is, the cam plate 130 functions as a pressing member for the contact terminal 112a, and the end portion 135a constitutes a pressing portion.

  Incidentally, in the cam plate 130, the rotation shafts 131 and 132 are provided by forming the opening 135 through the opening 133 from the rotation position where the rotation shafts 131 and 132 are provided. The distance from the rotation position to the opening 135 on the rotation end side can be increased, and thereby the tip portion 112c of the contact terminal 112a can be largely pushed down.

  Further, the other end 135b of the opening 135 formed in the cam plate 130 is brought into contact with the base side of the curved portion 112b of the contact terminal 112a when the cam plate 130 rotates more than a certain amount in the direction of arrow a. It has become. As a result, until the card inserted from the insertion slot 102 is pushed more than a certain amount, the end portion 112c of the contact terminal 112a is pushed down in the direction of arrow a by the above-described end portion 135a, and the card is further pushed into the cam plate 130. When it is rotated more than a certain amount, the contact terminal 112a is pushed down in the direction of arrow a by the other end 135b.

  As a result, the front end 112c of the contact terminal 112a is retracted outward from the card insertion space with respect to the terminal forming surfaces 10b, 20b, 30b, and 40b of the inserted card. It is possible to avoid the inserted card from hitting the front end portion 112c of the contact terminal 112a, and it is possible to prevent the front end portion 112c from being damaged.

  As described above, in a configuration in which a plurality of types of cards having different arrangements and outer shapes of the contact terminals 11a, 21a, 22a, 31a, and 41a are selectively inserted, the curved portion 111b of the contact terminal 111a of the first contact terminal group 111 is used. And the curved portion 112b of the contact terminal 112a of the second contact terminal group 112 must be arranged close to each other, and each contact terminal 111a of the first contact terminal group 111 and each contact terminal of the second contact terminal group 112 By being cantilever-supported with 112a from the opposite direction, it can be set as the structure where the curved parts 111b and 112b adjoined.

  In addition, an opening 133 that does not interfere with the curved portion 111b of the contact terminal 111a of the first contact terminal group 111 is formed in one cam plate 130, and the contact portion 112a of the second contact terminal group 112 is contacted with the distal end portion 112c. By forming the contact end portion 135a, only one of the contact terminals 112a and 112a arranged close to each other can be retracted by rotating the cam plate 130.

  In the case of the present embodiment, in the housing 104, there are differences between the insertion position of the first card 10, the insertion position of the second card 20, the insertion position of the third card 30, and the insertion position of the fourth card. Yes, for example, when inserting the second card 20 or the fourth card 40 and the case of inserting the first card 10 or the third card 30, the case of inserting the first card 10 or the third card 30 The terminal forming surface 10b or 30b of the first card 10 or the third card 30 is positioned closer to the contact terminal side than the terminal forming surface 20b or 40b of the second card 20 or the fourth card 40. Guided.

  That is, when the first card 10 or the third card 30 is inserted, the terminal forming surface 10b or 30b comes into contact with the contact terminal 111a of the first contact terminal group 111, whereas the second card When the 20th or fourth card 40 is inserted, the terminal forming surface 20b or 40b is not in contact with the contact terminal 111a of the first contact terminal group 111.

  As described above, there are cases where the contact terminal 111a is contacted or not depending on the inserted card. In the present embodiment, the opening 133 is formed in the cam plate 130, and the cam plate 130 rotates. Even when the card is inserted, a card (second card 20 or fourth card 40) that does not contact the contact terminal 111a is inserted by preventing the contact terminal 111a from being pushed down by the cam plate 130. Even if the cam plate 130 is rotated by the card, the contact terminal 111a is not pushed down.

  As described above, in the configuration in which the contact terminal 111a does not rotate (retract) even when the cam plate 130 rotates in the direction of the arrow a, the first card 10 that needs to contact the contact terminal 11a with the contact terminal 111a. When inserted, it is possible to obtain reliable contact between the contact terminal 111a and the contact terminal 11a.

  On the other hand, the contact terminals 112 a of the second contact terminal group 112 are extended from the back side of the card insertion space toward the insertion slot 102, similar to the third contact terminal group 113, and from the third contact terminal group 113. Also, the length of the contact terminal 112a is longer than the length of the contact terminal 113a by the amount provided on the insertion port 102 side. Thereby, in the contact terminal 112a, the curved portion 112b formed at the tip of the contact terminal 112a is disposed above the curved portion 113b of the contact terminal 113a (inward of the card insertion space). A sufficient contact pressure is obtained.

  In such a configuration in which the contact terminals are arranged above (inward of the card insertion space), the card inserted from the insertion slot 102 may hit the tip 112c of the contact terminal 112a and damage the tip 112c. is there. Therefore, in the present embodiment, the end portion 135a formed on the extending portion 134 of the cam plate 130 is configured to hold down the front end portion 112c of the contact terminal 112a, and when the card is inserted, the cam is inserted by the card. By rotating the plate 130 in the direction of the arrow a and retracting the front end 112c of the contact terminal 112a in the direction of the arrow a (outward of the card insertion space), the card is placed on the front end 112c of the contact terminal 112a. This prevents the tip 112c from being damaged.

  Incidentally, when the cam plate 130 is rotated in the direction of arrow a by the inserted card, a portion of the curved portion 112b of the contact terminal 112a that protrudes toward the card insertion space protrudes from the cam plate 130 toward the card insertion space. It becomes a state. Thus, when the second card 20 (FIG. 3) to be contacted with the contact terminal 112a is inserted, the curved portion of the contact terminal 112a is added to the contact terminal 22a of the second contact portion 22 of the second card 20. 112b can be contacted.

  As shown in FIGS. 6 and 7, in the internal space of the housing 104, a slide member 140 engaged with the inserted card and a coil spring for biasing the slide member 140 toward the insertion slot 102 are provided. 141 is provided. The coil spring 141 is used for a discharging operation when taking out the inserted card.

  Thus, as shown in FIG. 7, the first contact terminal group 111, the second contact terminal group 112, the third contact terminal group 113, the fourth contact terminal group 114, the cam plate 130, the slide member 140, the coil spring 141, etc. The card connector device 100 (FIG. 1) is configured by covering the upper portion with the cover 120 in a state where the components are arranged in the internal space of the housing 104.

  When the first card 10 is selectively inserted into the card connector device 100 described above, the cam plate 130 is rotated in the direction of arrow a by the first card 10 as shown in FIG. The contact terminals 112a of the second contact terminal group 112 are retracted in the direction of arrow a (outward of the card insertion space).

  Further, the contact terminal 111 a of the first contact terminal group 111 is pushed down by the inserted first card 10 without being affected by the rotation operation of the cam plate 130. And the site | part which protruded in the card | curd side of the curved part 111b contacts the contact terminal 11a of the 1st card | curd 10. FIG. In this case, at the contact portion, the bending portion 111b and the contact terminal 11a come into contact with each other with a force corresponding to the elasticity of the contact terminal 111a.

  On the other hand, when the second card 20 is selectively inserted into the card connector device 100, the cam plate 130 is rotated in the direction of arrow a by the second card 20, as shown in FIG. The tip 112c of the contact terminal 112a of the two-contact terminal group 112 retracts in the direction of arrow a (outside the card insertion space). As a result, the leading end 112c is retracted outward from the terminal forming surface 20b of the second card 20, and the leading end 112c is prevented from being damaged by the inserted second card 20. Then, a part of the curved portion 112b of the contact terminal 112a protrudes from the cam plate 130 toward the card side. In this state, the contact terminal 22a of the second card 20 and the curved portion 112b come into contact with each other. The curved portion 112b is pushed toward the cam plate 130 by the contact terminal 22a of the second card 20 by the amount protruding from the cam plate 130. Thus, the curved portion 112b of the contact terminal 112a comes into contact with the contact terminal 22a of the second card 20 with a force corresponding to the elasticity of the contact terminal 112a.

  As described above, since each contact terminal 111a of the first contact terminal group 111 is not affected by the rotation operation of the cam plate 130, when the cam plate 130 rotates in the arrow a direction, The curved portion 111b of the contact terminal 111a protrudes relatively large toward the card side from the cam plate 130. In the housing 104, when the second card 20 is inserted into the card insertion space, the second card 20 The second card 20 is guided so that the terminal forming surface 20b does not contact the curved portion 111b of the contact terminal 111a of the first contact terminal group 111.

  Further, in the contact terminal 113a of the third contact terminal group 113, the tip end portion 113c is in a state of being arranged outside the card insertion space from the terminal forming surface 20b of the inserted second card 20. Thus, when the second card 20 is inserted, the second card 20 does not hit the tip portion 113a but contacts the bending portion 113b, and then pushes down the bending portion 113b. Thereby, it is avoided that the front-end | tip part 113c hits the 2nd card | curd 20, and is damaged. Further, when the second card 20 is further inserted, a portion protruding to the card side of the bending portion 113b comes into contact with the contact terminal 21a of the terminal forming surface 20b of the second card 20. In this case, at the contact portion, the bending portion 113b and the contact terminal 21a come into contact with each other with a force corresponding to the elasticity of the contact terminal 113a.

  Incidentally, the tip end portion 113c of the contact terminal 113a is protected by the protection portion 108 formed on the bottom surface portion 105 of the housing 104, so that when the second card 20 or the like is inserted, the insertion position of the card can be changed. Even if it is shifted downward in the figure, the card hits the protection portion 108, and it is possible to avoid the tip portion 113c of the contact terminal 113a from being damaged.

  On the other hand, when the third card 30 is selectively inserted into the card connector device 100, the cam plate 130 is rotated in the direction of arrow a by the third card 30, as shown in FIGS. Then, the tip 112c of the contact terminal 112a of the second contact terminal group 112 retracts in the direction of arrow a (outward of the card insertion space). As a result, the leading end 112c is retracted outward from the terminal forming surface 30b of the third card 30, and the leading end 112c is prevented from being damaged by the inserted third card 30.

  The terminal forming surface 30b of the third card 30 is positioned below the terminal forming surface 20b of the second card 20, so that the third card 30 rotates the cam plate 130 within a certain range. When it is moved, it is pressed by one end 135a of the opening 135 of the cam plate 130 (FIG. 16), and when it is further rotated by a certain amount or more, it is contact terminal by the other end 135b of the opening 135. The base side of the curved portion 112b of 112a is held down (FIG. 17), thereby preventing the curved portion 112b of the contact terminal 112a from protruding from the cam plate 130 toward the card side (FIG. 18). As a result, the curved portion 112b of the contact terminal 112a can be prevented from contacting the third card 30.

  Further, in the contact terminal 113a of the third contact terminal group 113, the tip end portion 113c is arranged outside the card insertion space (lower in FIG. 16) than the terminal forming surface 30b of the inserted third card 30. In this state, when the third card 30 is inserted, the third card 30 does not hit the tip portion 113a but contacts the bending portion 113b, and then pushes down the bending portion 113b. Thereby, it is avoided that the front-end | tip part 113c hits the 3rd card | curd 30 and is damaged. Further, when the third card 30 is inserted, the portion of the bending portion 113b that protrudes toward the card comes into contact with the contact terminal 31a of the terminal forming surface 30b of the third card 30. In this case, in the contact portion, the bending portion 113b and the contact terminal 31a come into contact with each other with a force corresponding to the elasticity of the contact terminal 113a.

  Incidentally, as described above, the tip end portion 113c of the contact terminal 113a is protected by the protection portion 108 formed on the bottom surface portion 105 of the housing 104, so that when the third card 30 or the like is inserted, Even when the insertion position of the card is shifted downward in the figure, the card hits the protection portion 108, and it is possible to avoid the tip portion 113c of the contact terminal 113a from being damaged.

  On the other hand, when the fourth card 40 is selectively inserted into the card connector device 100, the cam plate 130 is rotated in the direction of arrow a by the fourth card 40 as shown in FIG. The tip 112c of the contact terminal 112a of the two-contact terminal group 112 retracts in the direction of arrow a (outside the card insertion space). As a result, the leading end 112c is retracted outward from the terminal forming surface 40b of the fourth card 40, and the leading end 112c is prevented from being damaged by the inserted fourth card 40.

  As described above, since each contact terminal 111a of the first contact terminal group 111 is not affected by the rotation operation of the cam plate 130, when the cam plate 130 rotates in the arrow a direction, The curved portion 111b of the contact terminal 111a protrudes relatively large toward the card side from the cam plate 130. In the housing 104, the fourth card 40 is inserted when the fourth card 40 is inserted into the card insertion space. The fourth card 40 is guided so that the terminal forming surface 40b does not contact the curved portion 111b of the contact terminal 111a of the first contact terminal group 111.

  Further, in the contact terminal 113a of the third contact terminal group 113, the tip end portion 113c is arranged outside the card insertion space (lower in FIG. 19) than the terminal forming surface 40b of the inserted fourth card 40. In this state, when the fourth card 40 is inserted, the fourth card 40 does not hit the tip portion 113a but abuts on the bending portion 113b, and then pushes down the bending portion 113b. Thereby, it is avoided that the front-end | tip part 113c hits the 4th card | curd 40 and is damaged.

  When the fourth card 40 is further inserted, the curved portion 114b of each contact terminal 114a of the fourth contact terminal group 114 comes into contact with the contact terminal 41a of the terminal forming surface 40b of the fourth card 40. In this case, in the contact portion, the curved portion 114b and the contact terminal 41a come into contact with each other with a force corresponding to the elasticity of the contact terminal 114a.

  The tip end portion 114c of the contact terminal 114a is protected by a protective member 151 fixed to the housing 104, so that when the fourth card 40 or the like is inserted, the insertion position of the card is downward in the figure. Even in the case of deviation, the card hits the protection member 151, and it is possible to avoid the tip portion 114c of the contact terminal 114a from being damaged.

  Thus, in the card connector device 100, the curved portion 111b (first contact portion) provided on the contact terminal 111a of the first contact terminal group 111 and the contact terminal 112a of the second contact terminal group 112 are provided. Even if the curved portion 112b (second contact portion) is disposed close to the curved portion 112b, the cam plate 130 is provided to selectively push down only the curved portion 112b of the second contact terminal group 112. be able to.
