A plurality of positioning portions 242 projecting horizontally into the working groove 241 are staggered from the side of the working groove 241 away from the first side wall 21. Each of the conductive terminals 4 of the M328100 has an abutting portion 4A, a welded portion 4i, and a connecting portion 42 connecting the abutting portion 40 and the welded portion 41. Wherein, the connecting portion is formed integrally with the insulative housing 2; each abutting protrudes from the receiving space; the corresponding contact for connecting the inserted electronic card C is inside, and the soldering portion 4 is further outside the insulating body 2 and further Soldering to the corresponding circuit board p. In combination with Figures 3, 4, 5 (4), 5 (b), the detection switch 5 has a non-card state indicating that the card is not inserted and - a card status indicating that the card has been correctly inserted, and A first detecting terminal 50 and a second detecting terminal 51 are included. The first detecting terminal includes a connecting portion 5〇〇, and an extending end of the connecting portion 5 (10) extends toward the rear end 11 along the insertion end (7) toward the receiving space 7. The elastic arm 5〇1, an abutting portion 5〇2 extending from the other end of the elastic arm 5〇1 to the receiving space 7 is extended horizontally from the other end of the connecting portion 500 and the elastic arm 5〇1 The holding portion 503' and a soldering portion 504 extending from the other end of the holding portion 5〇3 to the outside of the insulating body 2. In the embodiment, the extending direction of the elastic arm 5〇1 is designed to be consistent with the card insertion direction. The top card problem is effectively avoided. In an embodiment, the holding portion 503 further includes a self. a connecting portion 5〇〇 extending a rod portion 5〇3&, and a holding plate portion 503b extending from the rod portion 503a. The holding plate portion 5 has a plurality of spurs 5031 on both sides of the horizontal plane, the holding plate portion 503b The spurs 31 interfere with the holding groove mo of the detecting switch receiving groove 24, and the rod portion 5〇3a, the connecting portion 5〇〇, the elastic arm 5〇1 are received in the working groove 241, and the rod portion The 503a is vertically positioned in the vertical direction by being sandwiched by the positioning portion 242 which is disposed on the side of the working groove 241 and which is vertically staggered and protruded into the working groove. Of course, in other embodiments, the elastic arm 501 does not necessarily extend horizontally. The second detecting terminal 51 includes a fixing portion 510 that is molded and molded into the insulative housing 2, a soldering portion 511 extending from the side of the fixing portion 510, and a fixed portion 511 from the fixing portion 51. a laterally extending base portion 5 12 having no elasticity or a slight elasticity, the abutting portion 5 14 of the lower surface of the base portion 5ΐ2 and abutting protrusion 513 protruding from the lower surface of the abutting portion 514 (see FIG. 5) (b), 6(b), 7(b)). The base 512 and the abutting portion 514 and the abutting bumps 513 thereon The base portion 512 of the second detecting terminal is located above the elastic arm 501 of the first detecting terminal 50 and the extending direction of the base portion 512 and the elastic arm are as shown in FIGS. 5(b) and 6(b). The extending direction of the 5〇1 is perpendicular to each other. In the non-plug-in state, the elastic arm 5〇1 elastically abuts against the abutting portion 51 of the base 512 and is in full contact with the abutting bump 513; As shown in Fig. 7(b), the elastic arm 5〇1 is separated from the abutting portion 514 and the abutting bump 513. As shown in Figs. 5(a) and 5(b), the detecting switch 5 is not inserted when the electronic card is inserted. In a non-plugged state. At this time, the two detecting terminals 5〇, 51 are in abutting state, and the elastic arm 501 of the first detecting terminal 51 elastically abuts against the abutting portion 514 of the second detecting terminal 51 and the abutting bump 513, and the detecting circuit The non-card signal is turned on. As shown in FIGS. 6(a) and 6(b), an electronic card C is inserted into the electronic card connector 1, and when it is not inserted, the elastic arm 501 of the first detecting terminal 5 is still abutting against the second The abutting portion 5 上 on the base 5丨2 of the terminal 5丨 is detected and is in full contact with the abutting bump 5 13 , and the detecting switch 5 is in a non-plugged state. As shown in FIGS. 7(a) and 7(b), as the advancement of the electronic card C is in place, the front end of the electronic card C gradually moves over the docking portion 502 of the first detecting terminal 50; the docking portion 502 is on the electronic card C. Under the pressure, the elastic arm 501 is driven by its own elasticity to lower the M328100. At this time, the base 512 of the second detecting terminal is not elastic due to the force of the electronic card, so it is stationary, and the elastic arm In the case of 501, the external force is made: the abutting bump 5 of the second detecting terminal 51 and the abutting portion are separated from each other. That is, the detection switch 5 is switched from the non-plugged state to the plugged state. The detection of the sub-card connection H of the present invention _, because it only needs to act on the elastic arm with the first detection terminal when the operation is performed, and the second detection end 2 needs 2 force action, so a relatively small space is required. And the elastic displacement of the month b is effective enough to prevent the elastic fatigue of the elastic arm of the first detecting terminal, and the guarantee is integrated with the insulating body and does not have the elastic arm, so the compact structure occupies a small work space and the production cost is low. Moreover, since the extending direction of the elastic arm and the holding portion of the first detecting terminal coincides with the insertion direction of the electronic card, the occurrence of the top card phenomenon during the card insertion process can be effectively prevented.
