Description
Technical field
The present invention relates to a kind of SIM (SubscriberIdentity Module: subscriber identification module) card slot of mobile communication terminal, relate in particular to a kind of less installing space that on the circuit board of mobile communication terminal, occupies, can improve the accessory installation rate of circuit board, firmly support simultaneously SIM card, the SIM card slot of the stable mobile communication terminal that is connected of guarantee circuit board and SIM card.
Background technology
In the occupation mode of mobile communication terminal, at present realize that at European Region the occupation mode of commonly usedization is GSM (Global System for Mobile Communication: global system for mobile communications, the to call GSM in the following text) mode as time division multiple access way.
The mobile communication terminal that described GSM mode adopts uses SIM card, SIM card carries microprocessor and storage chip, storing the required nearly all information of terminal that starts, not only comprise userspersonal informations such as password, especially also storing the information of corresponding datas such as comprising telephone number, network number.
For the circuit board that makes described SIM card be connected to mobile communication terminal (to call terminal in the following text) is provided with the SIM card slot.Described SIM card slot forms terminal is combined in state in the housing, when a side that makes described terminal is connected to circuit board terminal, described housing is fixed on the circuit board of terminal.
Fig. 1 is the plane graph of an example of known SIM card slot, as shown in the figure, SIM card slot 100 is combined in the rectangular housing 110 a plurality of splicing ears 120, known SIM card slot 100 is welded on the circuit board 130 of terminal splicing ear 120, simultaneously housing 110 is fixed on the circuit board 130 of terminal.
But the situation of SIM card slot and SIM card bad connection often takes place in the structure of terminal in the splicing ear of known SIM card slot and the join dependency of SIM card.Promptly, SIM card realizes connecting when being pushed to SIM card slot direction, in this connecting moves under the effect that is incorporated into the battery on the terminal, the SIM card that is in the on-fixed state is moved, and its contact keeps the unstable possibility that is connected with the splicing ear of SIM card slot.
Owing to described reason, the SIM card slot 200 with the lid 230 that is used for supporting SIM card has as shown in Figure 2 been proposed.But this SIM card slot 200 is when keeping that SIM card is stable and connecting, and its size is 230 excessive because of covering, and takies than large tracts of land when being installed in circuit board terminal 240.Therefore, because the SIM card slot occupies excessive area with respect to circuit board terminal, hindered the installation of other accessory.
Summary of the invention
The present invention is just at defective that exists in the above-mentioned prior art and deficiency, and provide a kind of for circuit board for mobile communication terminal, need less installing space and the stable SIM card slot that connects the mobile communication terminal of SIM card.
For realizing described purpose, the invention provides a kind of SIM card slot of mobile communication terminal, comprising: socket body is arranged on terminal enclosure or the circuit board, comprise shaft-like connecting portion and pair of terminal joint portion, described shaft-like connecting portion is connected with described pair of terminal joint portion; Splicing ear is arranged on described terminal joint portion, and is connected with the circuit board of described terminal, is connected with the contact of SIM card with the circuit board with described terminal; The hook-type support member is arranged on the terminal joint portion of described socket body and outwards and protrudes, and supports the SIM card that is connected with described splicing ear.
The SIM card slot of mobile communication terminal of the present invention can be obtained following effect: the SIM card slot is under the prerequisite that keeps its function of performance, be arranged on circuit board terminal with minimal size, thereby the space that circuit board terminal is used to install accessory enlarges relatively, has improved accessory installation rate.In addition, the contact of SIM card is able to stable connection SIM card slot splicing ear by means of the hook-type support member, thereby has fundamentally prevented the bad connection between SIM card and SIM card slot.

Embodiment
With reference to the accompanying drawings, describe preferred embodiment of the present invention in detail.
Fig. 3 is the structural representation of an embodiment of SIM card slot of the present invention, Fig. 4 is the longitudinal sectional drawing of the splicing ear of SIM card slot of the present invention, Fig. 5 is the connection status longitudinal sectional drawing of SIM card slot of the present invention and SIM card, and Fig. 6 is the plane graph that SIM card slot of the present invention is arranged on the circuit board for mobile communication terminal state.
As shown in the figure, SIM card slot 1 of the present invention comprises socket body 10 and splicing ear 20.
Splicing ear 20 is arranged on the terminal joint portion 12 of socket body 10, and splicing ear 20 1 ends are connected in circuit board terminal 40, and the other end is connected with the contact 62 of SIM card 60.
Wherein, but splicing ear 20 insert the brachycephalic of socket body 10 and constitute the best to have elasticity.That is, compare with the employed banding pattern terminal of known SIM card slot, the installing space that the splicing ear of brachycephalic needs is littler, thereby reduces the size of socket body, and further enlarges the accessory installing space of circuit board terminal.
In the present embodiment, splicing ear 20 comprises round end housing 21 and terminal round end 23.Round end housing 21 is connected and is arranged on the terminal joint portion 12 of socket body 10 with circuit board terminal 40, and is provided with the spatial portion 25 towards SIM card 60 closures.And, spatial portion 25 inner faces of terminal round end 23 contact round end housings 21, flexible member 22 inserts and is arranged in the described spatial portion 25, and terminal round end 23 is connected with the contact 62 of SIM card 60.And round end housing 21 is provided with and connects pin 24, is arranged on the circuit board terminal 40 by the mode that connects the pin insertion.
Be provided with the hook-type support member 30 that is used to support SIM card in the terminal joint portion 12 of socket body 10, in socket body 10, keep stable installment state so that be connected and installed in the SIM card 60 of splicing ear 20.Support member 30 left and right symmetricallies are arranged on the both-side ends of terminal joint portion 12.Wherein, support member 30 all is arranged on the both sides of terminal joint portion as shown in this embodiment, but in other embodiments, two support member are arranged on the pair of terminal joint portion by diagonal, the set holding power to SIM card can be provided equally.
Wherein, it is good that support member 30 is set to apart from circuit board terminal 40 surperficial certain altitudes, keeps and circuit board terminal 40 contactless states, thereby guarantees the accessory installing space of circuit board 40 to greatest extent.
As mentioned above, SIM card slot 1 makes the installing space that takies circuit board 40 realize minimizing, so have the effect of relative expansion circuit board terminal 40 accessory installing spaces when connecting SIM card 60.
In addition, support member 30 keeps the contactless state with circuit board terminal 40, does not hinder the accessory of circuit board 40 to install.SIM card 60 is installed under the effect of support member 30, can makes that contact 62 is stable to be connected with splicing ear 20 SIM card slot 1.
