Embodiment
Fig. 2 is the vertical view of the chip card connector of one embodiment of the invention.Please refer to Fig. 2, the chip card connector 200 of present embodiment comprises that a body 210, a metal cap body 220, one first power pin 230, a second source pin 240, one the 3rd power pin 250, detect pin 260 and a plurality of signal pin 270a, 270b, 270c, 270d, 270e and 270f.Body 210 has a storage tank 210a, can hold chip card 280, and metal cap body 220 then is covered on the body 210.280 of chip cards have a plurality of power supply connection pad 280a and 280b, with a plurality of signal bonding pad 280c, 280d, 280e, 280f, 280g and 280h.First power pin 230, second source pin 240, the 3rd power pin 250 and detection pin 260 all are configured to body 210, and wherein an end of an end of second source pin 240 and the 3rd power pin 250 is given prominence to respectively at storage tank 210a.
When chip card 280 inserts storage tank 210a and is filled to the location, the power supply connection pad 280a of the pairing chip card 280 of an end in contact of second source pin 240, and another power supply connection pad of an end in contact of the 3rd power pin 250 280b.In addition, signal bonding pad 280c, 280d, 280e, 280f, 280g and the 280h on the chip card 280 then respectively with the end in contact of pairing signal pin 270d, 270a, 270c, 270b, 270f and 270e.Wherein, the main function of signal bonding pad 280c, 280d, 280e and 280f is respectively stored data-signal, ground signalling, clock signal and reset signal in the transmission chip card 280.
Fig. 3 is the circuit block diagram of the chip card connector of one embodiment of the invention.Please refer to Fig. 3, in the present embodiment, the chip card connector 200 of Fig. 1 is configurable in electronic installation 10.Electronic installation 10 for example is a mobile phone, and can comprise a circuit board 12.Circuit board 12 for example has a power end 12a and an earth terminal 12b, and chip card connector 200 then is arranged on the circuit board 12.First power pin, the 230 one ends of chip card connector 200 are electrically connected to power end 12a, and earth terminal 12b then electrically connects with the metal cap body 220 that covers on the chip card connector 200 simultaneously.Detect pin 260 and couple second source pin 240 and the 3rd power pin 250 respectively.
Fig. 4 is the generalized section of the chip card connector of one embodiment of the invention.Please be simultaneously with reference to Fig. 3 and Fig. 4, detect pin 260 and for example can be a metal clips, when chip card 280 was not mounted to storage tank 210a, the end normality ground that detects pin 260 was to metal cap body 220 bendings, and contacting metal lid 220, this moment, chip card connector 200 was the states that are in ground connection.When chip card 280 inserted storage tank 210a and is filled to the location, an end that detects pin 260 bendings toward pressing down and to 230 bendings of first power pin, and was contacted first power pin 230 by chip card 280.
Go out as shown in Figure 3, because first power pin 230 couples power end 12a, so under the state that electronic installation 10 is started shooting, when detecting pin 260 contacts first power pin 230, power end 12a just can also power to chip card 280 by conducting to second source pin 240 and the 3rd power pin 250.In addition, as long as chip card 280 1 leaves the location in the storage tank 210a, detect pin 260 and can disconnect, and power end 12a is connected to the circuit of second source pin 240 and the 3rd power pin 250 and also can interrupts, and stops the power supply supply of chip card 280 with being connected just of first power pin 230.In the case, detecting pin 260 can contact with metal cap body 220 once again, recovers the state of ground connection.
What deserves to be mentioned is that the electronic installation 10 of present embodiment also can comprise a judging unit 14, it is coupled to the other end that detects pin 260.Detect that pin 260 contacts with metal cap body 220 and during ground connection, the earth terminal 12b that couples with metal cap body 220 produces a ground signalling, and detection pin 260 just is passed to ground signalling judging unit 14.If chip card 280 inserts, detect pin 260 contacts first power pin 230, power end 12a then produces a high potential signal, and for example voltage is greater than the signal of 1.5V, and sees through the transmission that detects pin 260 high potential signal is passed to judging unit 14.Judging unit 14 can be ground signalling or high potential signal according to detecting the signal that pin 260 be transmitted, and judges whether chip card 280 is mounted to the location, and the decision subsequent action, for example transmits the data of chip card 280 or start etc. again.
Though whether the judging unit 14 of present embodiment is to have chip card 280 to insert chip card connectors 200 by judging that the signal that detection pin 260 is transmitted is ground signalling or high potential signal, detecting.But in another unshowned embodiment, whether judging unit 14 also can be only detects pin 260 high potential signal that transmits and detects whether chip card 280 insertion chip card connectors 200 are arranged according to receiving.That is to say, when chip card 280 does not insert chip card connector 200, detect pin 260 and can not need ground connection, and can be normally contacting metal lid 220 not.When chip card 280 inserted chip card connector 200, chip card 280 drive detection pins 260 pressed down and contact first power pin 230, make high potential signal be sent to judging unit 14 via detecting pin 260.After judging unit 14 received high potential signal, can judge had chip card 280 to insert among the chip card connector 200.Thus, judging unit 14 just can not need judge whether that ground signalling imports into.
In sum, chip card connector of the present invention is accepted under the state of electronic installation start after the chip card insertion, and the power end of the circuit board of electronic installation just can be supplied with the required power supply of chip card.Relatively, chip card is as long as a location of leaving chip card connector, and the circuit of power end and connector just can disconnect, and stops the power supply supply of chip card.Thus,, just can not cause the phenomenon of each short circuit between pins of connector, electronic installation is damaged in the moment that chip card is installed or shifted out, or the data in the loss chip card.Therefore, but the hot plug of chip card connector supporting chip card of the present invention.In other words, when changing the chip card of electronic installation, do not need earlier electronic installation to be shut down, also can improve the convenience that electronic installation uses.
Though the present invention with embodiment openly as above; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking claims person of defining.
