cDMA short message terminal is a kind of intelligent signal transmission and processing unit, generally comprises box body, surface-mounted integrated circuit, integrated chip, USB interface and SIM card fixture.SIM card fixture in existing product adopts hard connecting mode mostly, by cover plate, is directly pressed in SIM card, forces it to contact with the signalling contact in fixture, thereby reaches the object of connection.This structure tends to occur that SIM card contacts bad phenomenon in signalling contact after having grown service time, and cover plate is often directly pressed SIM card and also likely caused the damage of SIM card.In addition,, due to SIM card small volume, therefore, putting into and taking out of SIM is all comparatively inconvenient; If SIM card works long hours, also can bring the too high problems such as its normal work that affect of heating.
Utility model content
The purpose of this utility model is to provide the fixedly CDMA short message terminal of SIM card of a kind of convenience.
To achieve these goals, by the following technical solutions: a kind of CDMA short message terminal, comprise box body, in box body, be fixed with a circuit board, on circuit board, be provided with integrated chip, the USB interface being connected with the external world is also laid in circuit board one end, it is characterized in that: on described circuit board, be also provided with SIM card fixture; Described SIM card fixture comprises base plate, the both sides of base plate the first half are provided with draw-in groove, are provided with slide plate in draw-in groove, and the surface on slide plate top has the signalling contact matching with SIM card, in the middle of slide plate, be provided with bar shaped louvre, slide plate bottom is fixed with two spring leafs that upwards arch upward; On the surface of described base plate lower end, be provided with the first buckle; On base plate, by connecting axle, be also connected with a cover plate, described cover plate can move around connecting axle; On described cover inner surface, be fixed with five stage clips, in the middle of cover plate, be provided with fin, on cover plate free end, be also provided with through hole, in through hole, be inserted with bayonet lock; On described cover plate outer surface, be also provided with the second buckle.
Described bayonet lock is the spring leaf of a S type, and two ends are provided with the barb of opposite direction.
Stage clip on described cover plate has on four four angles that lay respectively at cover plate, and another one is positioned at the center of cover plate.
Described slide plate one side is also provided with driving lever, and the outside of draw-in groove is extended in this driving lever one end.
The utility model principle is simple, easy to use, by five stage clips on cover plate, presses SIM card, realizes cover plate and is connected with the elasticity of SIM, can promote greatly the effect that contacts of SIM card and signalling contact, can extend the useful life of SIM card simultaneously; In addition, can also be by the coordinating of draw-in groove and bayonet lock and the first buckle and the second buckle, realize being completely fixed of SIM card, and the heat radiation can guarantee that SIM works time of fin on cover plate and the bar shaped louvre on slide plate; User can operate slide plate by driving lever and slidably reciprocate and realize the function that SIM card is sent into draw-in groove or taken out draw-in groove, can automatically upspring when slide plate is extracted out one end of SIM of the spring leaf on slide plate, and person easy to use puts into or takes out SIM card.Of the present utility model cheap for manufacturing cost, there is stronger practical value.

Fig. 2 is the structural representation of SIM card fixture in Fig. 1;
Fig. 3 is that the A of Fig. 2 cover plate is to view;
Fig. 4 is the schematic diagram of bayonet lock in Fig. 2;
Fig. 5 is the outer surface view of Fig. 2 cover plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 5, a kind of CDMA short message terminal, comprises box body 1, in box body 1, be fixed with a circuit board 2, on circuit board 2, be provided with integrated chip 3, the USB interface 4 being connected with the external world is also laid in circuit board 2 one end, is also provided with SIM card fixture 5 on circuit board 2; Described SIM card fixture 5 comprises base plate 501, the both sides of base plate 501 the first half are provided with draw-in groove 502, in draw-in groove 502, be provided with slide plate 513, the surface on slide plate 513 tops has the signalling contact 503 matching with SIM card, in the middle of slide plate 513, be provided with bar shaped louvre 511, slide plate 513 bottoms are fixed with two spring leafs that upwards arch upward 512; On the surface of described base plate 502 lower ends, be provided with the first buckle 508; On base plate 501, by connecting axle 504, be also connected with a cover plate 505, described cover plate 505 can be around connecting axle 504 motions; On described cover plate 505 inner surfaces, be fixed with five stage clips 506, in the middle of cover plate 505, be provided with fin 514, on cover plate 505 free ends, be also provided with through hole 510, in through hole 510, be inserted with bayonet lock 507; On described cover plate 505 outer surfaces, be also provided with the second buckle 509.
