Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the invention will be further described.
embodiment mono-
As shown in Figure 1, Figure 2 and Figure 3, a kind of interrupt switch structure of SIM card, comprises SIM card holder 1, also comprises the conductive pin of paired setting, and conductive pin, for interrupting pin shell fragment 3, interrupts the laminated structure of pin shell fragment 3 for bending.Interruption pin shell fragment 3 is provided with a pair of, and this is welded on cell phone mainboard 2 interrupting pin shell fragment 3, and an interruption pin shell fragment 3 is connected with interrupt signal circuit, and another interrupts pin shell fragment 3 and is connected with earth signal circuit.The back side of SIM card holder 1 is provided with conductive layer, and in the time that SIM card holder 1 is inserted into working position, two interruption pin shell fragments 3 are butted on respectively the both sides at SIM card holder 1 back side.
As shown in Figure 7, interrupt pin shell fragment 3 and be provided with projection 31, this projection 31 is arranged in interruption pin shell fragment 3 and is butted in the one side at SIM card holder 1 back side.The solder side 32 interrupting on pin shell fragment 1 is provided with Gold plated Layer, and interrupts pin shell fragment 3 and be provided with the through hole 33 that runs through solder side, and when welding, scolding tin can see through through hole 33 emit the back side for solder side 32, increases the reliability of welding.The making material that interrupts pin shell fragment 3 is superhard stainless steel, can guarantee to interrupt the lasting elastic force of pin shell fragment 3, occurs failure phenomenon after avoiding using a period of time.The material thickness that interrupts pin shell fragment 3 is 0.1mm to 0.2mm, can reduce the space between SIM card holder 1 and cell phone mainboard 2, is conducive to the lightening design of mobile phone.
When use, SIM card is put into SIM card holder 1, SIM card holder 1 is inserted in mobile phone, SIM card holder 1 is inserted while putting in place, two interruption pin shell fragments 3 are butted on respectively the both sides at SIM card holder 1 back side, now, interrupt signal circuit is by interrupting conductive layer and the earth signal circuit communication at pin shell fragment 3 and SIM card holder 1 back side, thus the information that formation SIM card is inserted.While taking out SIM card, first SIM card holder 1 is extracted from mobile phone, now SIM card holder 1 departs from interrupts pin shell fragment 3, and interrupt signal circuit and earth signal circuit are cut off, and mobile phone forms the information that SIM card is pulled out.
embodiment bis-
