  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an explanatory view showing a place where a card connector 10 which is a connector according to an embodiment of the present invention is combined with a mating connector 20. FIG. 2 is a plan view showing the card connector 10 shown in FIG. 3 is a cross-sectional view seen from the direction of arrows III-III in FIG.

  As shown in FIGS. 1 to 3, the card connector 10 according to the present embodiment includes a substrate 11, a metal card connector terminal 12, and an insulating member 13.

  The substrate 11 is formed including an insulator such as a resin. On the substrate 11, a metal strip-shaped card connector terminal 12 is provided. That is, the substrate 11 supports the card connector terminal 12. The card connector terminal 12 extends in one direction from the edge of the substrate 11 (substrate edge 11a). In the present embodiment, the board edge 11 a is an edge where the card connector 10 contacts the mating connector 20.

  The card connector terminal 12 is a member that contacts a metal member such as the mating connector terminal 21 in order to electrically connect the card connector 10 to the mating connector 20. The card connector terminal 12 may be formed of a solid metal, or may be formed of a solidified liquid metal such as solder.

  The insulating member 13 includes, for example, an insulator such as a liquid resin such as a solder resist. The insulating member 13 is applied so as to cover the edge (terminal edge 12a) extending in the extending direction of the card connector terminal 12 which is a metal terminal from the side and from above. That is, the insulating member 13 is applied on the substrate 11 and the card connector terminal 12 so that the contact portion 12b on the card connector terminal 12 that contacts the mating connector 20 is exposed.

  The insulating member 13 may cover both of the edge portions (terminal edges 12a) extending in the extending direction of the card connector terminal 12 from the side and from above. Moreover, the insulating member 13 may cover the edge (terminal edge 12a) of the card connector terminal 12 so that the width of the insulating member 13 on the upper surface of the card connector terminal 12 which is a metal terminal becomes constant. Of course, the insulating member 13 may be a solid insulator formed by including a resin having a shape for holding the card connector terminal 12.

  The insulating member 13 covers the edge (terminal edge 12a) extending in the extending direction of the card connector terminal 12 from the side and above, so that the convex portion 13a by the insulating member 13 is formed on the card connector terminal 12. Is formed. A concave portion 14 for inserting the mating connector 20 is formed in the card connector 10 by the side surface of the convex portion 13 a and the contact portion 12 b on the card connector terminal 12 that contacts the mating connector 20.

  As shown in FIG. 1, the mating connector 20 is inserted into the recess 14 of the card connector 10, and the mating connector terminal 21 made of metal and the card connector terminal 12 come into contact with each other at the contact portion 12b.

  Since the edge (terminal edge 12a) of the card connector terminal 12 is covered with the insulating member 13, the metal member such as the mating connector terminal 21 does not contact the edge (terminal edge 12a) of the card connector terminal 12. . Further, since the mating connector 20 is inserted into the recess 14, the recess 14 also serves as a guide for inserting the mating connector 20.

  Thus, when the card connector 10 according to the present embodiment comes into contact with a metal member such as the card connector terminal 12 included in the counterpart connector 20, a part of the edge of the card connector terminal 12 is difficult to drop off.

  The present invention is not limited to the above embodiment.

  FIG. 4 is a plan view showing a card connector 10 according to another embodiment of the present invention. FIG. 5 is a cross-sectional view as seen from the direction of arrows V-V in FIG.

  As shown in FIGS. 4 and 5, the card connector 10 according to the present embodiment includes a board 11 (first board 11-1 and second board 11-2), card connector terminals 12, and the like. And an insulating member 13.

  The first substrate 11-1 and the second substrate 11-2 are, for example, a prepreg, a base material of a printed board, and the like, and are formed including a resin or the like.

  The insulating member 13 includes, for example, an insulator such as a liquid resin such as a solder resist. The insulating member 13 is applied on the first substrate 11-1. Of course, the insulating member 13 may be solid.

  The card connector terminal 12 is formed by, for example, solidification of a liquid metal such as solder that has not been coated with an insulating member 13 such as a solder resist or has been poured into a region on the first substrate 11-1. . In this manner, the surface of the card connector terminal 12 (card connector terminal surface 12c) is substantially flush with the surface of the insulating member 13 (insulating member surface 13b). Thus, the first substrate 11-1 supports the card connector terminal 12. The card connector terminal 12 extends in one direction from the edge (substrate edge 11a) of the first substrate 11-1. The card connector terminal 12 is provided to contact a metal member such as the mating connector terminal 21 in order to electrically connect the mating connector 20 and the card connector 10.

  The second substrate 11-2 is mounted on a plane formed by the card connector terminal surface 12c and the insulating member surface 13b so as to cover the boundary line B1 between the card connector terminal surface 12c and the insulating member surface 13b. The The second substrate 11-2 may be integrally formed as a whole, but may be composed of a plurality of members. The terminal layer formed of the card connector terminal 12 and the insulating member 13 and the second substrate 11-2 are bonded with, for example, an adhesive.

  Thus, since the edge (terminal edge 12a) of the card connector terminal 12 is covered with the insulating member 13, the metal member such as the mating connector terminal 21 and the edge of the card connector terminal 12 (terminal edge 12a). Do not touch.

  Thus, also in the card connector 10 according to the present embodiment, a part of the edge of the card connector terminal 12 is difficult to drop off when contacting the metal member such as the mating connector terminal 21.

  The present invention is not limited to the above embodiment.

  For example, as shown in the plan view of FIG. 6, a notch 15 may be formed at the end of the insulating member 13. This makes it easier to insert the card connector 10 into the mating connector 20.

  Further, the substrate 11 and the insulating member 13 may be integrally formed. That is, the card connector 10 covers a metal card connector terminal 12 formed in a strip shape and a bottom surface of the card connector terminal 12, and covers an edge of the card connector terminal 12 in the long side direction from the side and from above. Insulating member 13 may be provided.

  Further, the present invention may be applied to the card connector 10 in which the terminal layers formed of the card connector terminals 12 and the insulating members 13 and the substrate 11 are alternately stacked in a plurality of layers.

  Further, the card connector 10 and the mating connector 20 may be in contact with each other through the plurality of contact portions 12b. Moreover, the contact part 12b may be formed in the some surface which the card connector 10 has.

  The present invention is also applicable to connectors other than the card connector 10 and electronic devices that are directly electrically connected to the counterpart connector 20.
