Further, a closing surface 24A is formed between the closing surface 24A of the cover body 15A and the portion where the protective portion 23A is formed, and the card edge portion protrudes from the closing surface 24A.

  The protective portion 23A is formed integrally with the cover body 15A so that the end surface of the card edge portion 14 of the substrate 12 is covered, and the end surface of the card edge portion 14 protruding from the closing surface 24A, that is, the counterpart connector 31. It is formed so that the side to be inserted and the both side surfaces are covered and protected. That the end face of the card edge portion 14 is covered means that the protective portion 23A is formed and covered with the same thickness as the thickness of the substrate 12. Note that the thickness of the protective portion 23A may be slightly thicker than the thickness of the end surface. Further, the protective portion 23A is formed to have a thickness also in the horizontal direction with respect to the substrate surface. The outer side of the horizontal thickness may have a curved corner portion, or a gradually narrowed wedge shape. Also good. By doing in this way, since the card edge part 14 of the board | substrate 12 is covered with the protection part 23A, the impact by dropping can be relieved and the protection part 23A is provided in the card edge part 14 of the board | substrate 12. Thus, when the card edge terminal 13 and the counterpart connector 31 are connected, the substrate 12 can be prevented from being damaged due to contact with the contact 38 of the counterpart connector 31.

  Further, the protective portion 23A has an opening 26A so that the card edge terminal 13 is exposed, and comes into contact with the contact 38 of the mating connector 31 through the opening 26A. Further, a partition wall portion 27 </ b> A is formed so that the opening portion 26 </ b> A is positioned between each of the formed card edge terminals 13. The partition wall portion 27A extends from the protection portion 23A to the closing surface 24A. The opening 26A is partitioned by the closing surface 24A, the partition wall 27A, and the protection part 23A, and one opening 26A is provided at one place of the card edge terminal 13. By forming the partition wall portion 27A in this manner, the strength of the opening portion 26A can be increased, and a drop impact and damage during connection can be further suppressed. Furthermore, when the liquid has entered the opening 26A, the card edge terminals 13 are partitioned at each location, so that the liquid that has entered one section is prevented from coming into contact with the card edge terminals 13 in other sections, A short circuit of the substrate 12 can be suppressed.

  Further, the partition wall portion 27A is formed on the upper side and the lower side of the protection portion 23A, and the partition wall portion 27Aa formed on the upper side and the partition wall portion 27Ab formed on the lower side are provided alternately. (Hereinafter, the upper and lower partition walls 27Aa and 27Ab may be simply referred to as partition walls 27A). That is, the lower partition wall portion 27Ab is formed between the upper partition wall portion 27Aa and the partition wall portion 27Aa, and by forming the same, it is formed alternately. Therefore, the card edge terminals 13 are also formed alternately on the upper side and the lower side of the substrate 12. Since the partition wall portion 27A is formed in close contact with the substrate 12, no gap is formed between the partition wall portion 27A and the substrate surface. By doing in this way, the whisker that has been a problem when the surface of the card edge terminal 13 is formed by tin plating is formed so that the partition wall portion 27A is in close contact with other card edge terminals 13. The contact is suppressed, and a short circuit of the substrate 12 can be suppressed.

  As for the manufacture of the card member 11A, as shown in FIG. 12, the upper and lower molds 43 and 44 having the space S cut into the shape of the card member are formed, and this mold is formed. When the substrates 43 and 44 are combined, the substrate 12 is disposed, and an insulating material is injected into the space S of the molds 43 and 44 to perform molding. In addition, since it is well-known about molding, detailed description is abbreviate | omitted.

  As described above, according to the card member 11A of the second embodiment, in the substrate having the card edge terminal 13, the card edge portion 14 in which the card edge terminal 13 serving as a contact portion connected to the counterpart connector 31 is formed is exposed. Since the other portion of the substrate is molded integrally with the synthetic resin material, the liquid is prevented from coming into contact with the substrate surface of the card member 11A, and a high waterproof effect can be obtained.

  Further, the configuration of the counterpart connector 31 and the connection between the card member 11A and the counterpart connector 31 in the second embodiment are the same as those in the first embodiment, and thus the description thereof is omitted.

  According to the card edge connector 10A of Embodiment 2 assembled in this way, in addition to the waterproof property of the card member 11A, it is possible to obtain an excellent waterproof property by being liquid-tightly connected to the counterpart connector 31. become.
