Therefore, at above-mentioned technical problem, be necessary to provide a kind of structure improved electronic card coupler that has, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of electronic card coupler, and it can guarantee that conducting terminal closely is retained on the insulating body, improves the soldering reliability of conducting terminal.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of electronic card coupler, in order to the grafting electronic cards, it comprises insulating body and is located at plurality of conductive terminals on the insulating body, insulating body comprises base portion and the receiving space that can accommodate electronic cards, the base portion of insulating body is provided with the projection of some intervals setting and the location notch between adjacent projections, conducting terminal comprises the contact site that extends in the receiving space, be housed in the interior location division of location notch and the weld part of self-align extension, wherein, described projection is provided with in location notch projection and is pressed on convex closure on the conducting terminal location division.

Compared with prior art, the utlity model has following beneficial effect: the convex closure on the projection is pressed on the location division, can eliminate the location division is housed in behind the location notch and the gap that is produced between the projection, the location division that prevents conducting terminal takes place loosening, thereby can guarantee that conducting terminal closely is retained on the insulating body, improve the soldering reliability of conducting terminal weld part.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

[embodiment]

See also Fig. 1 and shown in Figure 4, the most preferred embodiment of the utility model electronic card coupler 100 is a kind of CF (Compact Flash) card connectors, it can be welded on the circuit board (not shown), and in order to grafting CF card (not shown), this electronic card coupler 100 comprises insulating body 1, be located at the conducting terminal 2 on the insulating body 1 and insulating body 1 is fixed on retaining piece 3 on the circuit board.

See also Fig. 1 to shown in Figure 6, insulating body 1 comprises base portion 11, pair of sidewalls 12 of extending forward from the left and right sides of base portion 11 that along continuous straight runs extends and the receiving space 14 that is surrounded by base portion 11 and this two side 12.Base portion 11 is provided with some terminal grooves 115 that run through base portion 11 front and back and be provided with for two rows, base portion 11 is provided with projection 112 and the location notch between adjacent projections 112 111 that some intervals are provided with in the rear end below the terminal groove 115, projection 112 and location notch 111 vertically extend and are arranged to a row along left and right directions, the projection in same location notch 111 of each projection 112 has a pair of convex closure 113, and corresponding convex closure 113 positions, the rear end of base portion 11 all are concaved with the fluting 114 that connects with location notch 111.Be equipped with slot 13 that inserts for the CF card and the draw-in groove 125 of accommodating retaining piece 3 on the sidewall 12.

Conducting terminal 2 comprises contact site 21, the holding parts 22 that extends back from contact site 21 rear ends, bend the location division 23 of extension and the weld part 24 that self-align 23 lower end bends extension backward downwards from holding parts 22 rear ends.The contact site 21 of conducting terminal 2 is a column structure, the holding parts 22 of conducting terminal 2 is retained in the terminal groove 115 of insulating body 1 base portion 11, contact site 21 extends terminal groove 115 forward and extends in the receiving space 14 to connect with the CF card, the location division 23 of conducting terminal 2 is housed in the location notch 111 of insulating body 1, the weld part 24 of conducting terminal 2 is welded on the circuit board, convex closure 113 on the projection 112 is pressed on the both sides of location division 23, can eliminate location division 23 and be housed in the gap that is produced between location notch 111 backs and the projection 112, prevent that conducting terminal 2 location divisions 23 from taking place loosening, thereby can guarantee that conducting terminal 2 closely is retained on the insulating body 1, improve the soldering reliability of conducting terminal 2 weld parts 24.When being assembled in conducting terminal 2 on the insulating body 1, the location division 23 of conducting terminal 2 will produce the plastic cement bits with convex closure 113 interferences on the projection 112, because corresponding convex closure 113 positions, base portion 11 rear ends are provided with fluting 114, the plastic cement that produced bits will be fallen in the fluting 114 and can not constitute influence to location division 23, thereby can guarantee the normotopia degree and the flatness of conducting terminal 2 weld parts 24.
