Description
Technical field
The utility model relates to a kind of communication cartridge.
Background technology
communication cartridge 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, is directly pressed in SIM card by cover plate, 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 the damage of SIM card often directly pressed SIM card and also likely cause by cover plate.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 communication cartridge of the fixing SIM card of a kind of convenience.
To achieve these goals, by the following technical solutions: a kind of communication cartridge, 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 circuit board, be also provided with SIM card fixture; 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 base plate lower end, be provided with the first buckle; On base plate, be also connected with a cover plate by connecting axle, cover plate can move around connecting axle; On cover inner surface, be fixed with five stage clips, in the middle of cover plate, be provided with fin, the free-ended surface of cover plate is provided with spring, and one end of bayonet lock is hinged on the second buckle of cover plate outer surface, and the middle part of bayonet lock is connected with spring; Bayonet lock is the spring leaf of a S type, and two ends are provided with the barb of opposite direction.
Stage clip on cover plate has on four four angles that lay respectively at cover plate, and another one is positioned at the center of cover plate.
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, presses SIM card by five stage clips on cover plate, 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 bar shaped louvre on fin and slide plate on cover plate; User can operate slide plate by driving lever and slidably reciprocate to realize SIM card is sent into draw-in groove or taken out the function of draw-in groove, can automatically upspring in the time that 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 communication cartridge, comprises box body 1, is fixed with a circuit board 2 in box body 1, is provided with integrated chip 3 on circuit board 2, and 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; 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 base plate 502 lower ends, be provided with the first buckle 508; On base plate 501, be also connected with a cover plate 505 by connecting axle 504, cover plate 505 can move around connecting axle 504; On cover plate 505 inner surfaces, be fixed with five stage clips 506, in the middle of cover plate 505, be provided with fin 514, the free-ended surface of cover plate is provided with spring 510, and one end of bayonet lock is hinged on the second buckle 509 of cover plate outer surface, and the middle part of bayonet lock is connected with spring; Bayonet lock is the spring leaf of a S type, and two ends are provided with the barb of opposite direction.
Stage clip 506 on cover plate 505 has on four four angles that lay respectively at cover plate 505, and another one is positioned at the center of cover plate 505.
Bayonet lock 507 is the spring leaf of a S type, and two ends are provided with the barb of opposite direction.
Slide plate 513 1 sides are also provided with driving lever 515, the outside that draw-in groove 502 is extended in these driving lever 515 one end.
