Embodiment

Please refer to Fig. 2, shown in Figure 3, the utility model preferred embodiment provides a kind of buckling device of sim card connector, and this card connector includes a base 1, a loam cake 2, and a plurality of terminal 3.Wherein:

One end of this base 1 is notch part, respectively is formed with a lug 11 in the corresponding two side on base 1 non-notch part end limit, is provided with a chute 111 in the position of facing mutually of these lugs 11, and these chutes 111 are that the rotating shaft 21 with loam cake 2 snaps into rotating mechanism matchingly; On two corresponding sidewalls of base 1, be equipped with depressed part 12, and the end walls of these depressed parts 12 is inclined-plane 121 attitudes, with respect to being formed with protuberance 13 between two depressed parts 12, these protuberances 13 are and protrude in the depressed part 12 trapezoidally, and depressed part 12 is presented with the aspect that is divided into two; The first half in these depressed parts 12 also is respectively equipped with outstanding protuberance 122, and the below of a protuberance 122 therein is provided with a block piece 14; The protuberance 13, protuberance 122 and the block piece 14 that form on these depressed parts 12 and the depressed part 12 all are emphasis structures of the present utility model.

This loam cake 2, its corresponding two side 23 respectively is formed with a rotating shaft 21, and these rotating shafts 21 are that the chute 111 with above-mentioned base 1 is matching mechanism; Centre position at these sidewalls 23 then is provided with barrier sheet 22, and this barrier sheet 22 is tending towards parallel inwardly recessed than sidewall, and promptly the distance of barrier sheet 22 and opposite side barrier sheet 22 is less than the distance between sidewall and another sidewall; Each side establish a button mouthfuls 24 in barrier sheet 22, these button mouths 24 are to form the key that flexibly supports portion 25, also be to be shielded in these interior protuberances 122 by loam cake 2 when contacting at support division 25, then can be exposed to outer catch mechanism (as shown in Figure 6) by button mouth 24.

Described depressed part 12 is that base 1 fastens the matching mechanism that the back permission is slided before and after the work with loam cake 2 in its scope, protuberance 13 is then by stopping mutually by the support division 25 of loam cake 2, loam cake 2 after making base 1 and fastening can only operate in the scope of its depressed part 12 (please assist referring to Fig. 4,5 and shown in Figure 7), simultaneously, the loam cake 2 that slides can be by the protuberance 122 and the interaction that flexibly supports portion 25 by depressed part 12, make loam cake 2 under the state of locking, can't upwards raise (please assist) referring to shown in Figure 6, when the portion of flexibly supporting 25 slides in the scope of depressed part 12, its top tip part 251 with flexible support division 25 will contact at block piece 14 (as shown in Figure 5), when applying top tip part 251 that external force makes support division 25 and

cross block piece

14,2 barrier effects at top tip part 251 and block piece 14 of this mobilizable loam cake are issued to and hold stable effect (as shown in Figure 7), thereby make that this 2 of loam cake that are fastened on base 1 can be free movable.

After described barrier sheet 22 loam cakes 2 are fastened on base 1, this barrier sheet 22 can be close to depressed part 12 positions between protuberance 122 and the protuberance 13, this barrier sheet 22 is under the restriction of the wall between protuberance 122 and the protuberance 13 simultaneously, also can only in its corresponding depressed part 12 positions, operate (seeing also shown in Fig. 5, the figure figure) back and forth, by this, the excessive phenomenon that breaks away from base 1 that cause of the external force in the time of can preventing because of promotion loam cake 2 effectively takes place.

In sum; only be a kind of preferred embodiment, be not limited to protection range of the present utility model, every equivalent structure that utilizes this specification and accompanying drawing to carry out changes; do not breaking away under the spirit of the present utility model, all should be contained in the utility model claim in.
