Embodiment
For ease of better understanding the utility model, now the utility model is further explained in conjunction with some embodiment of the present utility model.
As shown in Figure 2, the construction of switch that is used for intelligence card connector 10 according to the utility model one preferred embodiment comprises a first terminal 11 and one second terminal 12 that almost parallel extends.This first terminal 11 has the connecting portion 111 that one first extension 110, extends from 110 bendings of this first extension, and one by these connecting portion 111 bendings and with this first extension 110 arm 112 of extending of cocurrent and parallel roughly.This arm 112 comprises the postbrachium 1120 that extends from connecting portion 111 bending, the ancon 1121 that extends of these postbrachium 1120 bendings certainly downwards, this ancon 1121 upwardly extending forearms 1122 certainly, and the metacarpus 1123 that extends from these forearm 1122 bendings.This second terminal 12 has one first extension 120, and a butting section 121 from these first extension, 120 extensions.Metacarpus 1123 tops of the first terminal 11 and are located in the form of sheets in this butting section 121, and are convenient to contact with metacarpus 1123 under the state that closes.In addition, first extension 110,120 of two- terminal 11,12 all comprises the weld part 1100,1200 of being located at front end, so that respective terminal 11,12 is soldered on the circuit board (not shown).As Fig. 3, in the present embodiment, the normality of this construction of switch 10 is for opening, and promptly the metacarpus 1123 of the first terminal 11 does not contact with the butting section 121 of second terminal 12.
As Fig. 4, this construction of switch 10 is located at the opposite end 25 of the socket 20 of an intelligence card connector 1 chip cards 3 insertions.Please in conjunction with Fig. 5, this construction of switch 10 is aimed at the type zone 30 (being equally applicable to not have the corresponding region of the smart card of type) of the smart card 3 after inserting.When smart card 3 inserts, as be inserted into the tram, then the ancon 1121 of this first terminal 11 of upper surface 31 front ends of this smart card 3 meeting ejection.Whole arm 112 is lifted, and then make the butting section 121 (please in conjunction with Fig. 6) of its metacarpus 1123 these second terminals 12 of rising contact.Whether correctly this moment, this construction of switch 10 went to off status by the state of opening, and produced one and insert signal, detect smart card 3 purpose of insertion thereby reach.
As shown in Figure 7, this construction of switch 10 ' arm 112 ' can also be provided with the mode that arm among Fig. 3 112 turns over turnback.So, when smart card 3 inserts, by the first terminal 11 ' the guiding of ancon (not shown), the lower surface (not shown) of smart card 3 can be in contact with it ejection, and reach metacarpus 1123 ' with butting section 121 ' contact by not touching, promptly by opening the conversion of state to off status.Can reach equally and detect the purpose whether smart card 3 correctly inserts.
Please return Fig. 4, an intelligence card connector 1 that comprises construction of switch 10 of the present utility model comprises: a shielding casing 21, a terminal maintainance block 22, an insulating body 23, a construction of switch 10 and plurality of conductive terminals 24.This construction of switch 10 is together accommodated and remains in the terminal maintainance block 22 with this plurality of conductive terminals 24, and this construction of switch 10 is located at 30 the place aheads (being equally applicable to not have the smart card corresponding region in type zone), type zone of the smart card 3 of insertion, is conducting terminal 24 lefts (with reference to figure 5) that contact with smart card 3 upper contacts 32 among the figure.When smart card 3 inserted, this construction of switch 10 can detect whether it is correct insertion.As insert and correctly then produce a correct signal that inserts, reporting system is operated smart card 3; Otherwise, then produce and do not insert information by system, require the user to insert again, thereby avoided follow-up because of the incorrect issuable misoperation of smart card 3 insertions.
In addition, electronic card coupler can adopt the electronic card coupler of stacking mode and other function for the requirement of saving the space, combines as fast card (expresscard), PC RAM (random access memory) card (PCMCIA) connector etc.As shown in Figure 8, an electronic card coupler 4 has been integrated expresscard connector 41 and intelligence card connector 42, can use the construction of switch that the utility model discloses in this intelligence card connector 42.
In the practical application, the normality of this construction of switch can be off status, and promptly the metacarpus of the first terminal contacts (turning over turnback in metacarpus and the foregoing description can achieve the goal) with the butting section of second terminal.When smart card inserts, the butting section of the metacarpus of the first terminal and second terminal contact disconnection, open state and produce the insertion signal and be converted to one by an off status.
Technology contents of the present utility model and technical characterstic disclose as above, yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and done all replacement and modifications that does not deviate from the utility model spirit.Therefore, protection range of the present utility model should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present utility model and modifications, and is contained by the present patent application claim.
