Abstract

The utility model relates to a mobile phone protective shell with a built-in SIM (Subscriber Identity Module) card switching device. The mobile phone protective shell is characterized in that the mobile phone protective shell further comprises built-in SIM card slots, a switching switch and a flexible circuit board that are connected together. The mobile phone protective shell further comprises a pasted part of the flexible circuit board used for pasting and leading out pins of the SIM cards. With the adoption of the mobile phone protective shell, a mobile phone is externally connected with the other SIM card, a main used SIM card can be switched by the switch, thereby realizing the condition that one phone has double cards with one-standby; the double cards can execute call transfer mutually, thereby ensuring that two phone numbers can be connected.

Description

A kind of mobile phone protecting sheathing of realizing that the two cards of SIM are singly treated

Technical field

The utility model relates to the communications field, relates in particular to the mobile phone protecting sheathing.

Background technology

At present, all face the difficult selection of a plurality of common carriers when the cellphone subscriber networks, but many mobile phones has only a sim card slot.For the 3G mobile user, lose not open original phone number for various reasons, insert the 2G SIM of a commmunication company usually in the mobile phone, but wanted to use the 3G SIM that can bring into play 3G mobile high speed Internet access performance again simultaneously, but there is not solution.Therefore, need a kind of two card handoff technique to address this problem.

The utility model content

For addressing the above problem, the utility model provides a kind of mobile phone protecting sheathing, can realize that two cards singly treat, perhaps establishes calling transfer mutually through two cards and realizes two idle functions.

The utility model discloses a kind of mobile phone protecting sheathing, have the mobile phone protecting sheathing, comprise the built-in sim card slot that links together, diverter switch, flexible PCB.Said mobile phone protecting sheathing also comprises: the flexible PCB adhesive portion that is used to paste and draw the SIM pin.

The beneficial effect of the utility model is, can provide the cellphone subscriber when need not changing old number, enjoys the new function that new digit is brought.The cellphone subscriber just can be switched two telecom operators' SIMs flexibly through shutting down (or offline mode), stirring diverter switch, start (or line model), enjoys the communication service that heterogeneous networks brings.SIM can be usim card, less radio-frequency RF-SIM card, SIMpass card, micro SIM.

Description of drawings

Fig. 1 is the schematic diagram of the utility model mobile phone protecting sheathing;

Fig. 2 is the application sketch map in a kind of mobile phone protecting sheathing.Wherein left side SIM1 flexible circuit pad pasting can be attached on the regular handset SIM, inserts mobile phone; Also can be cut into lesser calorie, the lesser calorie of mobile phones such as adaptive iphone4 (micro SIM) along interior lines.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done further detailed description.

The principle of the mobile phone protecting sheathing of the utility model is shown in Figure 1.

External SIM2 draw-in groove 300 is arranged in the mobile phone protecting sheathing, pastes 200 through flexible PCB and film SIM and is connected.

It is double-sided flex circuit that the film SIM pastes 200, is attached to during use on the SIM1 card, is placed in mobile phone SIM 1 draw-in groove 100.This circuit except the 7th pin, the two-sided connection of 1,2,3,5 pin, 6 pin are not used.The film SIM pastes the end that 200 the 7th pin are connected with SIM1 draw-in groove 100 and goes into the public pin of switch, is convenient to the switch both sides and switches; The film SIM pastes the end that 200 the 7th pin are connected with SIM1 and goes into switch one end; The 7th pin of external SIM2 draw-in groove 300 connects the other end of switch.All the other 1,2,3,5 pin and film SIM paste 200 the corresponding connection of 1,2,3,5 pin.

In the use, push the lower end of switch 400, use the SIM1 card; Push the upper end of switch 400, use the SIM2 card.

In embodiment, the mobile phone protecting sheathing that external SIM2 draw-in groove 300 embeds can be different and different along with the concrete shape of mobile phone.

Those skilled in the art can also carry out various modifications to above content under the condition of spirit that does not break away from the definite the utility model of claims and scope.Therefore the scope of the utility model is not limited in above explanation, but confirm by the scope of claims.
