[embodiment]

See also Fig. 1 to shown in Figure 6, be the first execution mode view of the utility model sim card connector; Comprise: the insulator 10 that is formed by insulating material, be immobilizated in 8 butts 30 on the insulator and be immobilizated in the outer metal shell 20 of insulator, this terminal and metal shell are to be made by the metallic conduction material.

Insulator 10 has diapire 11, connect the pair of sidewalls 12 of diapire both sides, be positioned at diapire reaches the cavity 14 that is made of this diapire and sidewall with sidewall one end and interconnective retaining wall 13, insert in this cavity for the SIM card module, diapire comprises the conduit 15 that is arranged side by side into two rows, to accommodate terminal in wherein, the convex closure 17 that the sidewall lateral surface is provided with groove 16 and outwards protrudes out, the lateral surface of retaining wall is provided with holddown groove 18.

Metal shell 20 comprises end face 21, is positioned at the side 22 of end face both sides and connects the side and be positioned at the bottom surface 23 of insulator diapire downside, this end face is provided with the through hole corresponding with the conduit of diapire 24, the side is provided with the through hole 25 of the convex closure that is retained on sidewall and is held in shell fragment 26 in the groove 16, this metal shell also is provided with the retaining sheet 27 in the holddown groove 18 that is retained on retaining wall simultaneously, by the structure of this metal shell and cooperatively interacting of insulator, so that being fixed on, metal shell is retained on the insulator.

Ginseng Fig. 4 and shown in Figure 5, terminal 30 comprises holding board 31, welding foot 32 and contact site 33, holding board 31 is provided with conduit 34, contact site 33 protrudes out in cavity from this conduit, this contact site is provided with the connecting portion 35 that connects holding board, extends and the main elastic arm 36, the hypoelasticity arm 37 that are arranged side by side and be positioned at contact on the primary and secondary elastic arm from connecting portion, vertical direction at vertical diapire, the contact of main elastic arm more protrudes into cavity than the contact of hypoelasticity arm, and the end of hypoelasticity arm more protrudes into cavity than the end of main elastic arm.The end of above-mentioned hypoelasticity arm is longer than the end of main elastic arm.
