[embodiment]

Shown in Fig. 2,3,4,5, the utility model electric connector 100 is used to electrically connect storage device (not shown) to printed circuit board (PCB) (not shown), and it comprises insulating body 1, plurality of conductive terminals 2 and a lid 3.

Insulating body 1 roughly is rectangular structure, and it comprises that diapire 10 reaches from the extended straight up sidewall 12 of diapire 10.In the present embodiment, sidewall 12 form by three sidewalls 12 and sidewall 12 forming a receiving space 101 is used to accommodate storage device jointly with diapire 10.Diapire 10 comprises that the plurality of terminals accepting groove 102 that is used to accept the upper surface 103 of storage device and run through upper surface 103 is used to accommodate conducting terminal 2, and upper surface 103 is provided with the protuberance 1031 that extends upward.In the present embodiment, protuberance 1031 is some projections that roughly are square, and it is provided with near terminal containing slot 102.Wherein relative two side 12 comprises near the medial surface 121 of receiving space 101 and and medial surface 121 opposite external side faces 122.Each lateral surface 122 is provided with a pair of hollow-out parts 1222 and a pair of holding part 1221.In the present embodiment, holding part 1221 is recessed to form for lateral surface 122 bottom-up parts.Lateral surface 122 is provided with a chute 1223 near terminal position.

Conducting terminal 2 is housed in the insulating body 1, it comprises that the holding parts 22 that is housed in the insulating body 1, the elastic portion 21 that extends upward from holding parts 22 1 ends reach from the extended weld part 23 of holding parts 22 other ends, and the end of elastic portion 21 is provided with contact site 211 and is used to be electrically connected to storage device.See also shown in Figure 4ly, the contact site 211 of conducting terminal 2 is with respect to the height of the upper surface 103 of insulating body 1 height greater than protuberance 1031, guarantees that effectively the contact site 211 of conducting terminal 2 realizes that with storage device excellent electrical property is connected.

Lid 3 movably is articulated on the insulating body 1, and it comprises and roughly is the relative side wall 32 of flat main board 31 and autonomous agent plate 31 extended straight down two.Each side wall 32 is provided with a make-up and holds sheet 321, and it comprises from the extended straight down connecting portion 3210 of side wall 32 and from the clamping part 3211 of connecting portion 3210 to another side wall 32 direction horizontal-extendings setting.Clamping part 3211 bends inwards and horizontal-extending from connecting portion 3210 root edges, and its end is provided with a guidance part that protrudes out 3212.Guidance part 3212 is to extend with respect to the direction that insulating body 1 slides along lid 3 from clamping part 3211, and cooperates the slip with guiding lid 3 with the bottom of holding part 1221.The end of side wall 32 is provided with a cylindrical pivot joint block 322.
