Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a card adapter 20 and a small card 10 attached to the card adapter 20 according to an embodiment of the present invention. The card adapter 20 has an outer shape and positions of terminals (connector-side terminals 27) that are substantially the same as those of a standard card, and the card adapter 20 is mounted with a small card 10 smaller than the standard card. Is attached to a connector (not shown) provided in a slot of a computer or the like to which a standard card is to be attached. A different small card 10 can be mounted, and each terminal of the small card 10 is electrically connected to a terminal of a connector having the same function as the terminal.

  That is, in FIG. 1, the card adapter 20 has an insertion port 22 into which the small card 10 is inserted at one end of the box-shaped housing 21, and the small card 10 inserted from the insertion port 22. A plurality of card-side terminals (card connection portions) 25 that come into contact with the plurality of terminals and a plurality of connector-side terminals (connector connection) arranged in accordance with the arrangement of the plurality of terminals of the connector to which the card adapter 20 is attached Part) 27 and a holding part 31 that cantilever-holds each card-side terminal 25 and each connector-side terminal 27 inside the casing 21. The card side terminal 25 and the connector side terminal 27 are formed in a flat plate shape by a metal plate. The holding part 31 is made of an insulator such as resin.

  The housing 21 has a substantially flat lower housing 35, an insertion guide portion 33 having an insertion port 22 formed at one end of the lower housing 35, and an upper housing 36 that covers the upper surface of the lower housing 35. It is constituted by. Frame portions 32a and 32b projecting upward along the side edges of the lower housing 35 are formed on the upper surface of the lower housing 35 so as to guide the edge of the small card 10 inserted from the insertion slot 22. Has been made. Further, a holding portion 31 is disposed between the frame portions 32 a and 32 b in the vicinity of the other end portion 35 b of the lower housing 35, and the connector side terminal 27 cantilevered by the holding portion 31 is connected to the lower housing 35. Are arranged along the other end 35b. A plurality of openings 38 are formed on the bottom surface of the other end 35 b of the lower housing 35 at positions facing the connector-side terminals 27, and the connector-side terminals 27 are connected via the openings 38. It is in a state exposed below the lower housing 35. This configuration is the same as that of the standard card, so that the card adapter 20 can be mounted in the same manner as the standard card with respect to a connector (not shown) for mounting the standard card. Yes.

  The holding portion 31 is made of a resin material, and is formed by molding so as to hold the card side terminal 25 and the connector side terminal 27. FIG. 2 is a perspective view showing the card side terminal 25 and the connector side terminal 27 before the holding portion 31 is formed. As shown in FIG. 2, the card side terminals 25 are formed with a terminal width corresponding to the terminal width of the terminals provided on the small card 10 and arranged at a pitch according to the arrangement pitch of the terminals of the small card 10. Has been. Thereby, when the small card 10 is mounted on the card adapter 20, the terminal of the small card 10 and the card side terminal 25 of the card adapter 20 come into contact with each other. The connector-side terminal 27 is formed with a terminal width corresponding to the terminal width of the connector that is the mounting target of the card adapter 20 (that is, the mounting target of the standard card), and according to the pitch of the terminal arrangement of the connector. Arranged at different pitches. As a result, when the card adapter 20 is attached to a connector of an electronic device such as a computer, the connector side terminal 27 of the card adapter 20 and the terminal of the connector come into contact with each other.

  The card side terminal 25 and the connector side terminal 27 have the same function based on the function assigned to each terminal of the small card 10 and the function assigned to each terminal of the connector to which the connector side terminal 27 is connected. The terminals are connected by a continuous forming part 41. The continuous forming portion 41 is a portion where the card side terminal 25 and the connector side terminal 27 are integrally connected to each other in the holding portion 31.

  In FIG. 2, for example, the function assigned to the terminal of the small card 10 (FIG. 1) that contacts the card-side terminal 25a and the function assigned to the connector terminal that contacts the connector-side terminal 27a are the same function. In this case, the card side terminal 25a and the connector side terminal 27a are formed to be connected by the continuous forming portion 41a. Thus, when the card adapter 20 is attached to the connector in a state where the small card 10 is attached to the card adapter 20, the terminals of the small card 10 and the connector assigned the same function as the function assigned to the terminal are assigned. The terminal is electrically connected.

  Here, when the card side terminal 25b and the connector side terminal 27b correspond to the terminals of the same function of the small card 10 and the connector, it is necessary to connect the card side terminal 25b and the connector side terminal 27b. In this case, a continuous forming portion 41x of other terminals (card side terminal 25c, connector side terminal 27c) is arranged between these terminals 25b and 27b, so that the holding portion 31 formed by molding is arranged. In order to form a new continuous forming portion by crossing the continuous forming portion 41x so as not to contact the continuous forming portion 41x, a complicated manufacturing process is required. In the case of this embodiment, as a configuration for crossing the portions to which the terminals are connected without contacting each other, the portion to which one of the terminals is connected is arranged on the surface of the holding portion 31.

  That is, the card side terminal 25b is bent from the inside of the holding part 31 to the upper surface side of the holding part 31 in the base part 25b1 which is molded and supported by the holding part 31 (FIG. 1), and the bent tip The portion 25b2 is formed so as to be substantially flush with the upper surface of the holding portion 31.

  Further, the connector side terminal 27b is bent from the inside of the holding portion 31 to the upper surface side of the holding portion 31 in the support portion 27b1 which is molded and held by the holding portion 31 (FIG. 1). The part 27b2 is formed so as to be substantially flush with the upper surface of the holding part 31.

  As a result, as shown in FIG. 3, the front end portion 25b2 of the card-side terminal 25b and the front end portion 27b2 of the connector-side terminal 27b are exposed on the upper surface of the molded holding portion 31. In this state, a conductive printed body (conducting conductive material) having a very low electrical resistance including silver powder as a conductor so as to include the exposed portions of the tips of the terminals on the upper surface of the holding portion 31. The thin conductive layer 50 is formed by printing the conductive paste. Here, silver is used as the conductor, but the present invention is not limited to this, and other materials having similar characteristics can be used. The conductive portion 50 formed in this way is thinner than the plate thickness of the card side terminal 25 and the connector side terminal 27. Here, although the conduction | electrical_connection part 50 is formed by printing, this invention is not restricted to this, The conductor which can be formed thin similarly to what was formed by printing, for example, a conductor like a thin conductive sheet For example, the conductive portion 50 can be used. As a result, the leading end portion 25 b 2 of the card side terminal 25 b and the leading end portion 27 b 2 of the connector side terminal 27 b are connected to the conductive state by the conductive portion 50 on the surface of the holding portion 31.

  Thus, the card side terminal 25b and the connector side terminal 27b are connected in a conductive state on the surface of the holding portion 31 made of an insulator. In this case, as shown in FIG. 4, a continuous forming portion 41x of the card side terminal 25c and the connector side terminal 27c is disposed inside the holding portion 31, but the card side terminal 25b and the connector side terminal 27b Are connected to each other by the conductive portion 50 on the upper surface of the holding portion 31, so that the two connected portions are insulated from each other by the insulator constituting the holding portion 31.

  In the card adapter 20 having the configuration described above, when the small card 10 is inserted from the insertion port 22 (FIG. 1) and the terminal of the small card 10 and the card side terminal 25 of the card adapter 20 are brought into contact, the small card 10 These terminals are electrically connected to the connector side terminal 27 connected to the card side terminal 25 through the card side terminal 25.

  When the card adapter 20 is inserted into the slot of a computer or the like to which the small card 10 is attached, the connector-side terminal 27 of the card adapter 20 and the connector terminal of the slot come into contact with each other, and these are electrically connected. Connected to.

  Here, in the connector to which the card adapter 20 is attached, the function of each terminal of the connector is assigned so as to match the arrangement of the function assigned to each terminal of the standard memory card. Accordingly, when the small card 10 having a functional arrangement different from the functional arrangement of the standard card is used, the card side terminal 25 and the connector side terminal 27 are connected according to the functional arrangement of the terminals of the small card 10. The card adapter 20 is used.

  Thus, in the card adapter 20, the card side terminal 25 and the connector side terminal 27 are connected according to the arrangement of the functions assigned to the terminals of the small card 10, so that the card side terminal 25 and the connector side are connected. Between the terminals 27, there is a portion where the mutually connected parts intersect. In this intersecting portion, as described above, one of the intersecting connected portions is formed as the conductive portion 50 by printing the printed body (conductive paste) on the surface of the holding portion 31, and the inside of the holding portion 31. And the other connected part (continuous formation part 41x (FIG. 2, FIG. 4)) cross | intersects non-contactingly.

  In the card adapter 20 of the present embodiment, one of the connected parts is the surface of the holding part 31 in a configuration that avoids contact between two intersecting connected parts (continuous forming part 41x and conduction part 50). By being formed by printing, the connected portion (conducting portion 50) can be formed in a thinner layer. As a result, the card-side terminal 25 and the connector-side terminal 27 are connected as compared with the case where the conductive portion 50 is configured by attaching a thick part such as a jumper wire or a circuit board to the outside of the holding portion 31. The thickness at the portion to be removed can be further reduced. Thus, according to the above configuration, a much thinner card adapter 20 can be realized.

  In addition, according to the card adapter 20 of the present embodiment, a configuration in which a portion where the card side terminal 25b and the connector side terminal 27b are connected intersects a portion where the other terminals are connected (continuous forming portion 41). In this case, the conductive portion can be obtained by simply bending the front end portions 25b2 and 27b2 of the card-side terminal 25b and the connector-side terminal 27b that are part of one connected portion to the upper surface side of the holding portion 31. By printing 50, the card-side terminal 25b and the connector-side terminal 27b can be connected to each other in a conductive state so as to straddle the portion (continuous forming portion 41) to be connected between the other terminals. This eliminates the need for a complicated configuration such as a three-dimensional intersection of the portions to be connected by the metal plate inside the holding portion 31 formed by molding. Moreover, since the conduction | electrical_connection part 50 is thinner than the board thickness of the card | curd side terminal 25 or the connector side terminal 27, thickness can be made thinner than the thickness when two continuous formation parts are cross | intersected in three dimensions.

  Further, the holding part 31 is molded to hold the continuous forming part 41 x between the card side terminal 25 and the connector side terminal 27 in the holding part 31, and then the conduction part 50 is formed on the surface of the holding part 31. Thus, it is possible to avoid the manufacturing process of the molding from becoming complicated, and the card adapter 20 can be easily manufactured.

  In addition, by forming a plurality of conducting portions 50 on the surface of the holding portion 31 and connecting a plurality of sets of terminals, the degree of freedom in connection between the terminals can be ensured, and the degree of freedom in design is improved. be able to.

  In the above-described embodiment, the case where the portions where the card side terminal 25 and the connector side terminal 27 are connected to each other is crossed in a non-contact manner, but in addition to this, an electrical shield layer is formed. You may make it do. For example, as shown in FIG. 5, the shield layer 55 is formed by printing a conductive paste on the entire surface of the holding portion 31 where the conductive portion 50 is provided by printing. In this case, as shown in FIG. 6, an insulating layer 61 is formed at least between the shield layer 55 and the conductive portion 50, thereby making the conductive portion 50 and the shield layer 55 nonconductive. Thus, by making the conducting part 50 and the shield layer 55 non-conducting, the shield layer 55 can be formed on the entire surface on the upper surface side of the holding part 31 including the region where the conducting part 50 is formed. Incidentally, FIG. 6 and FIG. 7 to be described later schematically show cross sections of the holding part 31, the conduction part 50, and the shield layer 55, and the thickness of each layer is shown to be thicker than the actual thickness.

  On the surface of the holding portion 31 (FIG. 5), the leading end portion 25d2 of the grounding card side terminal 25d is exposed, and the leading end portion 27d2 of the grounding connector side terminal 27d is exposed. As a result, the grounding terminal and the shield layer 55 are connected in a conductive state, whereby the shield layer 55 is held at the ground potential, and electrical noise generated from each card side terminal 25 and connector side terminal 27 is reduced. Can be shielded. The grounding terminal connected to the shield layer 55 may be either the card side terminal 25d or the connector side terminal 27d.

  Further, as shown in FIG. 6, the shield layer 55 may be covered with an insulating covering portion 62. In this way, the shield layer 50 is insulated, thereby preventing a short circuit between the metal material and the shield layer 55 even when the housing of the card adapter 20 is made of a metal material. can do.

  Further, the shield layer 55 shown in FIG. 5 is formed on the entire surface of the holding portion 31, but the present invention is not limited to this. For example, the shield layer 55 is provided so as to avoid the formation region of the conduction portion 50. Also good. In this way, it is not necessary to form an insulating layer between the conduction part 50 and the shield layer 55. In this case, for example, as shown in FIG. 7, the respective surfaces of the conducting portion 50 and the shield layer 55 are covered with an insulating covering portion 62, thereby preventing a short circuit by coming into contact with a metal part. Can do.

  In the configuration described with reference to FIGS. 5 and 6, the same printing process as the process of printing the conductive part 50 on the surface of the holding part 31 is used by forming the shield layer 55 on the surface of the holding part 31 by printing. Thus, the shield layer 55 can be formed.

  Further, in the above-described embodiment, the case where the card side terminal 25 and the connector side terminal 27 are connected by the conductive portion 50 printed on the surface of the holding portion 31 has been described, but the present invention is limited to this. Instead, the present invention can also be applied to a case where at least two of the plurality of card side terminals 25 are connected or a case where at least two of the plurality of connector side terminals 27 are connected. For example, as shown in FIG. 8, when a set of card side terminals including two of the plurality of card side terminals 25 (card side terminals 25d and 25e) is used as a ground terminal, a part of these terminals ( For example, the leading end portions 25d2 and 25e2) are exposed on the surface of the holding portion 31, and the conductive portion 50 is formed by printing a conductive paste in a region including these two exposed portions. By this conduction part 50, the ground terminals (card side terminals 25d and 25e) of the card side terminals 25 can be connected to other terminals without contact. Thereby, even when only one of the card-side terminals 25d and 25e set as the ground terminal is used as a ground terminal when the small card 10 is connected, the other terminal is set to the ground potential. Can keep.

  Similarly, in the case of the connector side terminal 27, for example, when a set of connector side terminals including two of the plurality of connector side terminals 27 (connector side terminals 27d and 27e) is used as a ground terminal, Part of the terminals (for example, the tip portions 27d2 and 27e2) are exposed on the surface of the holding portion 31, and the conductive portion 50 is formed by printing a conductive paste in a region including these two exposed portions. By this conducting portion 50, the ground terminal (connector side terminals 27d, 27e) of the connector side terminals 27 can be connected to other terminals without contact. In the example shown in FIG. 8, the case where the ground terminals are connected to each other has been described. However, the present invention is not limited to this, and the card side terminal 25 is provided with a plurality of power supply terminals or the connector side terminal 27. This can also be applied to the case where a plurality of power supply terminals are provided. Also, the present invention can be applied when connecting signal terminals to which the same function is assigned.

  Moreover, in the above-described embodiment, the case where the card side terminal 25b and the connector side terminal 27b that are not connected to other terminals in the holding unit 31 are connected by the conducting unit 50 on the surface of the holding unit 31 has been described. However, the present invention is not limited to this, and even in the terminal continuously formed with the other terminals in the holding portion 31, a part of the terminal is exposed on the surface of the holding portion 31 to form the conduction portion 50. The conductive portion 50 can be connected to another terminal different from other terminals connected inside.

  In the above-described embodiment, the configuration in which the card-side terminals 25 are arranged in a row with respect to the connector-side terminals 27 arranged in a row and these are held by one holding portion 31 has been described. The present invention is not limited to this. For example, the present invention can also be applied when the card-side terminals 25 are arranged in a plurality of rows. In this case, either a configuration in which the holding unit 31 is provided in common for each row of the plurality of rows of card-side terminals 25 or a configuration in which the holding portion 31 is provided separately for each row of the rows of card-side terminals 25 may be used.
