Abstract
The invention discloses a drawer-type mobile phone SIM card inserting mechanism which comprises a metal bracket fixed on a circuit board and an SIM card holder connected with the metal bracket in an insertion manner. The SIM card holder includes a metal supporting plate and a plastic layer covered on the periphery of the metal supporting plate. Gaps are formed at positions, close to the metal bracket, of the plastic layer. After the SIM card holder is inserted into the metal bracket, portions, located at the gaps, of the metal supporting plate are in contact with the metal bracket. The drawer-type mobile phone SIM card inserting mechanism provided by the invention is high in solidity and low in production cost and can conduct the metal bracket to achieve an effect of PIN detection and solve the problem of hot plugging.
Description
Technical field
The present invention relates to a kind of SIM card plug-in unit, particularly relate to a kind of drawer type mobile phone SIM Ka Cha mechanism.
Background technology
Common common SIM card seat is generally placed on below battery of mobile phone, by the long muscle of structure, coordinates SIM card to take.And for the built-in equipment of battery, because battery cannot be taken, generally all select this SIM card seat of PUSH-PUSH, from equipment side perforate dress SIM card.But the SIM card seat reliability of PUSH-PUSH is all bad in the industry at present, and drop test is very easy to card.
Summary of the invention
The technical problem to be solved in the present invention is bad in order to overcome the SIM card seat reliability of mobile phone of internal battery plate in prior art, exists and falls the defect of easily falling card, and a kind of drawer type mobile phone SIM Ka Cha mechanism is provided.
The present invention solves above-mentioned technical problem by following technical proposals:
A Ka Cha mechanism, its feature is, it comprises: be fixed on the metallic support on a circuit board; The one SIM card holder of pegging graft with this metallic support, this SIM card holder comprises that a metal supporting plate and is coated on the plastic layer of this metal supporting plate periphery, this plastic layer all forms a breach near the position of described metallic support, when this SIM card holder is inserted after this metallic support, the part that this metal supporting plate is positioned at this indentation, there contacts with this metallic support.This SIM card holder is the structure of injection moulding scisse in film forming, since can reduce the thickness of complete machine, and work as SIM card holder while inserting metallic support, can this metallic support of conducting play the effect of detecting PIN, the problem of solution hot plug.
Wherein, this metallic support is provided with at least one reference column.Described reference column inserts this metallic support exactly for guiding and SIM card holder.
Wherein, the one end in this SIM card holder sensing mobile phone outside is provided with an end cap.Be convenient to push SIM card holder on the one hand, can improve on the other hand the contact area of SIM card holder and handset shell, improve SIM card holder and be arranged on the fastness on handset shell.
Wherein, drawer type mobile phone SIM Ka Cha mechanism also comprises that one for fixing the locked mechanism of the housing of this end cap and mobile phone.This locked mechanism can further improve the fastness that SIM card is inserted mechanism, prevents from falling the phenomenon of card.
Wherein, this locked mechanism comprises that correspondence is arranged at the screw on this end cap and this housing, and with the screw of this screw adaptation.
Wherein, this metallic support is installed on the back side of described circuit board.
Wherein, this metallic support comprises two metal sliding slots that are arranged in parallel, and is provided with a SIM card seat between described metal sliding slot.
In the present invention, above-mentioned optimum condition can combination in any on the basis that meets this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: drawer type mobile phone SIM Ka Cha of the present invention mechanism fastness is high, and production cost is low, can conducting metallic support play the effect of detecting PIN, solves the problem of hot plug.

Fig. 2 is the cutaway view that the drawer type mobile phone SIM Ka Cha mechanism in a preferred embodiment of the present invention is mounted to circuit board.
Fig. 3 is the vertical view that the drawer type mobile phone SIM Ka Cha mechanism in a preferred embodiment of the present invention is mounted to back of circuit board.
Fig. 4 is the cutaway view that the drawer type mobile phone SIM Ka Cha mechanism in a preferred embodiment of the present invention is assembled to mobile phone.
Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.
As shown in Fig. 1 ~ 4, mobile phone in the present embodiment comprises the back cover 100 of a mobile phone, one circuit board 200, this drawer type mobile phone SIM Ka Cha mechanism comprises the metallic support consisting of two metal sliding slots 1, is equipped with a reference column (not shown) on each metal sliding slot 1.Between metal sliding slot 1, be also provided with a SIM card seat 6 for reading SIM card internal information.Described metal sliding slot 1 and SIM card seat 6 are all arranged on the circuit board 200 back side, and the cell panel of mobile phone is positioned at the front of circuit board 200.
This drawer type mobile phone SIM Ka Cha mechanism also comprises a SIM card holder, and this SIM card holder comprises that one for placing the scisse 2 of SIM card, at the coated one deck plastic layer 3 in the periphery of scisse 2.The position of the upper surface of this plastic layer 3, close metal sliding slot 1 is all formed with a breach.When metal sliding slot 1 is inserted in SIM card holder, the part that scisse 2 is positioned at described indentation, there contacts with corresponding metal sliding slot 1.
One end of pointing to mobile phone outside in SIM card holder is provided with an end cap 4.In the present embodiment, this end cap 4 is formed in one with plastic layer 3.The fastness being connected with handset shell in order to improve end cap 4, this SIM card is inserted mechanism and is also comprised a locked mechanism, this locked mechanism comprises the screw being positioned on this end cap 4, and with the screw 5 of described screw adaptation.
During use, first SIM card is packed in SIM card holder, then SIM card support is entered in back cover 100, with screw 5, Kato is tightly locked on back cover 100.When SIM card holder is inserted or is extracted back cover 100, because metal sliding slot 1 and scisse 2 have the action of individual break-make, thus can play the function of detecting, thus hot plug problem solved.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection scope of the present invention.
