Description
Technical field
The present invention relates to a kind of SIM card holder and mobile terminal, particularly relate to a kind of SIM card holder and the mobile terminal that adopt PUSH-PUSH (pressure people-ejection) principle.
Background technology
Current SIM (client identification module) card has three kinds: standard SIM card, micro-SIM card (a kind of SIM card) and nano-SIM card (a kind of SIM card), the size of nano-SIM card is less than the size of micro-SIM card, and the size of micro-SIM card is less than again the size of standard SIM card.SIM card holder is the parts for SIM card of planting in mobile terminal (as mobile phone etc.), the SIM card holder of present main flow is applicable to standard SIM card usually, so use the user of micro-SIM card or nano-SIM card before micro-SIM card or the insertion of nano-SIM card are applicable to the SIM card holder of standard SIM card, the outer cover at micro-SIM card or nano-SIM card is often needed to adopt the cutting ferrule of plastic material with one, to make the size of micro-SIM card or nano-SIM card identical with standard SIM card.
The structure of brief description once existing SIM card holder below: see the SIM card holder generalized section shown in Fig. 1, SIM card holder generally includes base 1 and a top cover 2, described top cover 2 is connected with described base 1, to form one for holding the draw-in groove of the SIM card 3 of insertion.When SIM card 3 inserts draw-in groove, the SIM card 3 of insertion moves on the first surface 101 of described base 1, and described first surface 101 is the upper surface of the base 1 shown in figure.Described base 1 is provided with 6 contact flat springs 4 (merely illustrating 2 in Fig. 1), when SIM card 3 is inserted completely time, those contact flat springs 4 and the metal chip electrical contact in SIM card 3.The shape and structure of described contact flat spring 4 as shown in Figure 1, comprise the lug boss 403 of stiff end 401, free end 402 and between described stiff end 401 and described free end 402, described stiff end 401 is compared to the card inserting mouth of described free end 402 closer to described draw-in groove, described stiff end 401 is fixed under described first surface 101, described free end 402 and described lug boss 403 all unsettled on described first surface 101.Insert in the process of described draw-in groove in SIM card 3, the first inclined-plane 4031 of described lug boss 403 is stressed to be pressed down, and whole contact flat spring 4 becomes flat along with the insertion of SIM card 3.Exit after described draw-in groove until SIM card 3, described contact flat spring 4 restores to the original state.
If the SIM card 3 inserted is As mentioned above, formed by micro-SIM card or nano-SIM card 301 and cutting ferrule 302 fit; so this kind of SIM card usually there will be following situation when exiting described draw-in groove: see the P portion enlarged drawing shown in Fig. 2; there are some gaps due to micro-SIM card or between nano-SIM card 301 and cutting ferrule 302; exiting in process; the free end 402 of described contact flat spring 4 is triggered by those gaps; outwards SIM card 3 is pulled if continue; whole contact flat spring 4 will be caused to be upturned distortion, and then to cause SIM card holder to damage.
In addition, existing SIM card holder, especially adopt the SIM card holder of PUSH-PUSH principle, its structure is known in those skilled in the art, below in conjunction with Fig. 3-6, brief description SIM card holder plug-in card and the process of moving back card is once described:
See Fig. 3, described base 1 is also provided with pull bar 103, slide block 104, spring 105 and coordinated with described cam structure 102 for the cam structure 102, limiting the position of SIM card 3 in described draw-in groove and detects shell fragment 106.State when inserting without SIM card, one end of described pull bar 103 is positioned at A place (as Fig. 3); When SIM card 3 is inserted, described slide block 104 moves along the direction of insertion of SIM card 3, described spring 105 compresses, and when SIM card 3 is inserted into the bottom of described draw-in groove, described detection shell fragment 106 is squeezed, one end of described pull bar 103 moves to B place (as Fig. 4) by A, then, SIM card is resilience a little, and one end of described pull bar 103 moves to C place (as Fig. 5) by B, SIM card is locked in SIM card holder, and plug-in card process terminates; When moving back card, SIM card 3 is gently pressed in the bottom to described draw-in groove, and described detection shell fragment 106 is squeezed, and one end of described pull bar 103 moves to D place (as Fig. 6) by C, and then SIM card 3 is ejected, and one end of described pull bar 103 moves back to A place by D.
As can be seen from Fig. 3-6, B, C, D tri-place's distances are very near, all need very accurate so the one end controlling described pull bar 103 moves to from B the power that C place moves to D place again, during as moved to C place from B, if the power controlled is excessive, one end of described pull bar 103 will slip over C place from B and arrive D place, and can not be parked in C place, and then directly ejected after causing SIM card to be inserted, can not be locked.
