Description

A kind of communication module expanding unit of integrated client identification module

Technical field

The utility model relates to electronics zero device, relates in particular to a kind of improvement of communication module expanding unit of integrated client identification module.

Background technology

Current 3G (3G (Third Generation) Moblie technology) module on the market generally all only provides UIM (UserIdentity Model subscriber identification module) interface, the UIM deck is not provided, this has just determined this class 3G module can only be applied on the subscriber equipment that the MINI PCI-E of UIM deck interface is provided, and has seriously limited the range of application of 3G module.

Generally be by on subscriber equipment, placing the UIM deck in the existing technology to realize that UIM links to each other with the 3G module, for the subscriber equipment that the UIM deck is not provided, perhaps the UIM deck is integrated on the 3G module, perhaps adopt the UIM connector, this connector comprises deck and flexible PCB, it places the UIM card on deck, deck is provided with interface, make deck be connected with flexible PCB one end, the other end of flexible PCB is provided with the expansion card interface, is connected with MINI PCI-E interface on the subscriber equipment realizing.

The subscriber equipment of the MINI PCI-E interface of UIM deck is not provided on current market, when employing is integrated into 3G module on the 3G module with the UIM deck, because this generic module is few, therefore alternative is not strong, and adopt this UIM connector, the flexible PCB of connector fractures easily, reliability is not high, the UIM deck also can't be fixed, and the UIM connector injects the junction of 3G module and MINI PCI-E interface by force by flexible PCB, oppresses the golden finger contact of MINI PCI-E interface for a long time, damage the golden finger contact easily, this in addition connected mode is unreliable, if flexible PCB is corresponding with contact position incorrect, also causes short circuit between each signal easily.

The utility model content

The purpose of this utility model is to overcome the defective of prior art, and the communication module expanding unit that a kind of reliability height, ease for use are strong, can simplify a kind of integrated client identification module of subscriber equipment is provided.

The utility model is to realize like this, a kind of communication module expanding unit of integrated client identification module, comprise that one is provided with the expansion board of peripheral circuit, described expansion board is provided with first deck and second deck, and described first deck is connected by the circuit on the described expansion board with described second deck.

Further, described first deck is a MINI PCI-E deck; Described second deck is the UIM deck.Further, described first deck is located at the front of described expansion board, and described second deck is located at the reverse side of described expansion board.

Further, described first deck, described second deck are located at the same one side of described expansion board.

Further, an end of described expansion board is provided with golden finger, and described first deck is connected with described golden finger by the lead-in wire on the described expansion board.

Further, also be provided with fixing hole on the described expansion board, most the corresponding respectively described fixing holes of screw are fixed on described expansion board on the subscriber equipment.

The utlity model has following technique effect:

1) owing to the type of modules of integrated described second deck in the prior art is fewer, alternative is not strong, and the utility model is integrated in first deck and second deck on the described expansion board, and be connected by the circuit on the expansion board, be fit to all and meet the 3G module of MINI PCI-E standard interface, therefore increased the selection that the user uses the 3G module greatly; Simultaneously also need not on subscriber equipment, to design the second deck circuit again, make the design simplification of subscriber equipment.

2) the communication module expanding unit of the communication module expanding unit of 3G module and a kind of integrated client identification module, a kind of integrated client identification module and the interface between the subscriber equipment all are standard MINI PCI-E interfaces in the utility model, connect reliably, can not cause short circuit between each signal.

3) the utility model provides fixing hole according to MINI PCI-E construction standard, and most the corresponding respectively described fixing holes of screw are fixed on the subscriber equipment described expansion board very convenient.

Description of drawings

Fig. 1 is the utility model embodiment communication module expanding unit structural representation;

Fig. 2 is another structural representation of the utility model embodiment communication module expanding unit.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to Fig. 1-Fig. 2, the utility model embodiment provides a kind of communication module expanding unit 1 of integrated client identification module, comprise that one is provided with the expansion board 11 of peripheral circuit, described expansion board 11 is provided with first deck 111 and second deck 112, and described first deck 111 is connected by the circuit on the described expansion board 11 with described second deck 112.Because the type of modules of integrated described second deck 112 is fewer in the prior art, alternative is not strong, and the utility model is integrated in first deck 111 and second deck 112 on the described expansion board 11, and be connected by the circuit on the expansion board 11, be fit to all and meet the 3G module of MINI PCI-E standard interface, therefore increased the selection that the user uses the 3G module greatly; Also need not simultaneously on subscriber equipment (figure does not show), to design the second deck circuit again, make the design simplification of subscriber equipment.

Further, in the utility model specific embodiment structure, described first deck 111 is the MINIPCI-E deck; Described second deck 112 is UIM (User Identity Model subscriber identification module) deck; Particularly, described first deck 111 is located at the front of described expansion board 11, described second deck 112 is located at the reverse side of described expansion board 11, need to prove described first deck 111, described second deck 112 also can be arranged on the same one side of described expansion board 11, here owing to also be provided with some peripheral circuits on the expansion board 11, peripheral circuit is some resistance, electric capacity zero devices such as (figure do not show), with described first deck 111, described second deck 112 is arranged on one side can seem more crowded, so most preferred embodiment is with described first deck 111, described second deck 112 is arranged on the two sides of described expansion board 11, to save the space.
