  The card connector according to the present invention includes a base portion and arm portions extending forward from both ends of the base portion, and an accommodation space for accommodating the card is formed by the base portion and the arm portion, and penetrates the base portion. An insulating body having a plurality of terminal grooves, a contact portion that contacts the card, a holding portion that extends from one end of the contact portion and is held by the terminal groove of the insulating body, and is connected to the circuit board In a card connector including a plurality of conductive terminals including a connecting portion, a plurality of convex ribs are formed to protrude rearward at the rear end of the base portion, and an accommodation groove is formed between the convex ribs. And at least one convex portion projecting into the receiving groove is formed on each side surface of the convex rib, and the conductive terminal includes a positioning portion that connects the holding portion and the connection portion, and the conductive terminal is In the insulation body When it is worn, and the positioning portion and the convex portion of the insulating body so as to abut against the positioning portion is provided a card connector, characterized in that it is accommodated in the accommodation groove.

  Compared with the prior art, the card connector of the present invention has the following advantages, and the positioning portion is received in the receiving groove so that the positioning portion of the conductive terminal and the convex portion of the insulating body are in contact with each other. Thus, the movement of the conductive terminal can be restricted, and the conductive terminal can be stably held in the insulating body.

It is an assembly perspective view of the card connector according to the present invention. It is the assembly perspective view which looked at the connector for cards shown in Drawing 1 from another angle. FIG. 3 is an enlarged view of a portion indicated by a broken line of the card connector shown in FIG. 2. 1 is an exploded perspective view of a card connector according to the present invention. It is the disassembled perspective view which looked at the connector for cards shown in FIG. 4 from another angle. It is an enlarged view of the part shown with the broken line of the connector for cards shown in FIG.

  A preferred embodiment of the card connector 100 of the present invention will be described below with reference to FIGS.

  A card connector 100 of the present invention is mounted on a circuit board (not shown) and used to receive a CF (Compact Flash) card (not shown, hereinafter referred to as a card). A plurality of conductive terminals 2 held by the insulating body 1 and a holding member 3 for mounting the insulating body 1 on a circuit board are included.

  The insulating body 1 includes a base portion 11 arranged in the longitudinal direction and both arm portions 12 extending forward from both ends of the base portion 11. The base portion 11 and the both arm portions 12 accommodate cards. A space 14 is formed. The base 11 is formed with terminal grooves 115 penetrating in the front-rear direction and arranged in two rows, and is arranged on the rear side of the base 11 so as to stand vertically from the rear side of the base 11. A plurality of convex ribs 112 are formed so as to protrude, and a housing groove 111 is formed between the convex ribs 112, and a plurality of convex parts projecting toward the housing groove 111 are formed on both side surfaces of each convex rib 112. 113 are formed. An opening groove 114 communicating with the housing groove 111 is formed at a location corresponding to the convex portion 113 of the base portion 11.

  The arm portion 12 is formed with a guide groove 13 that communicates with the accommodation space 14 and guides insertion of the card, and an engagement groove 125 that accommodates and holds the holding member 3.

   The conductive terminal 2 is formed by a contact portion 21 that contacts a card, a holding portion 22 that extends from the contact portion 21 and is held by the terminal groove 115 of the insulating body 1, and is bent downward from the holding portion 22. Positioning portion 23 and a connection portion 24 extending from the end of positioning portion 23 and connected to the circuit board. The contact portion 21 has a pin shape and protrudes into the accommodation space 14 and is arranged in two rows. Is done. The positioning portions 23 are accommodated in the accommodating grooves 111 of the insulating main body 1 so as to be arranged in a line, and both side edges of the positioning portions 23 and the convex portions 113 formed on the convex ribs 112 come into contact with each other. 2 is restricted, the conductive terminal 2 is stably held by the insulating body 1, and the operation of connecting the connecting portion 24 to the circuit board is facilitated.

  In addition, since an opening groove 114 communicating with the accommodation groove 111 is formed at a position corresponding to the convex portion 113 of the base portion 11, when the conductive terminal 2 is attached to the insulating body 1, the positioning portion 23 and the insulating body The plastic waste generated by coming into contact with the first protrusion 113 falls into the open groove 114.

  The holding member 3 includes a locking portion 31 that is engaged with the engaging groove 125 of the insulating body 1 and a fixing portion 32 that is bent and extends from the locking portion 31, and the fixing portion 32 is a circuit. Bonded to the substrate.

  When the side edge of the positioning portion 23 of the conductive terminal 2 and the convex portion 113 of the insulating main body 1 abut, the movement of the conductive terminal 2 is limited, and the conductive terminal 2 is stably held by the insulating main body 1. Furthermore, the flatness of the connecting portion 24 of the conductive terminal 2 is ensured, which is advantageous for soldering work for connecting the connecting portion 24 to the circuit board.

  Although the present invention has been described in detail with reference to the best embodiment, the embodiment is merely illustrative and is not limited thereto.
