Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

An embodiment of the present application provides a card holder. Please refer to FIG. 1 and FIG. 2 for details. FIG. 1 is a schematic structural diagram of the card holder provided by the embodiment of the present application, and FIG. 2 is an exploded schematic view of the card holder shown in FIG. 1 .

The card holder 100 can be used to accommodate a Subscriber Identity Module (SIM) card. The card holder 100 may include a bracket 120 , a connecting member 140 and a detection elastic piece 160 . The connecting piece 140 and the detecting elastic piece 160 are both disposed on the bracket 120 . When the SIM card is not inserted into the card holder 100 , the detecting elastic piece 160 is electrically connected to the connecting piece 140 , and when the SIM card is inserted into the card holder 100 , the detecting elastic piece 160 and the connecting piece are electrically connected. 140 interval settings. Whether there is a SIM card inserted into the card holder 100 can be determined by detecting the connection state between the elastic piece 160 and the connector 140 . The detection of the physical contact and separation of the elastic piece 160 and the connector 140 can accurately obtain whether the SIM card is inserted into the card holder 100 , thereby improving the accuracy of detecting whether the SIM card is inserted into the card holder 100 .

It should be noted that, in the related art, a detection circuit connected to the SIM is arranged in the card holder. When the SIM card is not inserted into the card holder, the detection circuit is disconnected. When the SIM card is inserted into the card holder, the detection circuit is electrically connected with the SIM card, thereby A loop is formed, and then it is detected that the SIM card is inserted into the card holder. However, if the SIM card is not inserted into the card holder or the SIM card is invalid, it cannot be effectively detected.

This embodiment detects whether a SIM card is inserted into the card holder 100 by detecting the physical connection between the elastic sheet 160 and the connector 140 . When the SIM card is not inserted into the card holder 100, the detection elastic piece 160 abuts against the connector 140 to realize electrical connection. When the SIM card is inserted into the card holder 100, the detection elastic piece 160 is squeezed by the SIM card to separate it from the connector 140, so that the detection The elastic piece 160 is arranged at intervals from the connecting piece 140 , and the detection level of the elastic piece 160 is no longer affected by the connecting piece 140 . For example, when the SIM card is not inserted into the card holder 100, the detection spring 160 is electrically connected to the connector 140, and the connector 140 will affect the level of the detection spring 160. For example, if the level of the detection spring 160 is low, when the SIM card When the card holder 100 is inserted, the detection spring 160 is squeezed by the SIM card to separate it from the connector 140, the level of the detection spring 160 is no longer pulled down by the connector 140, and the detection spring 160 changes from a low level to a high level. Therefore, whether a SIM card is inserted can be identified and determined by detecting the level change of the dome 160. The level change of the detecting dome 160 is determined by detecting the physical connection or physical separation of the dome 160 and the connector 140, even if the SIM card is not inserted into the card holder 100. Whether the SIM card is in place or the SIM is invalid will not affect the detection of the detection shrapnel 160 , and can accurately detect whether the SIM card is inserted into the card holder 100 .

It should be noted that the first level and the second level can be set as required.

The embodiment of the present application also provides a card holder. Please continue to refer to FIG. 1 , and in conjunction with FIGS. 10 and 11 , FIG. 10 is another structural schematic diagram of the bracket, the connector and the detection spring in the card holder shown in FIG. 1 , and FIG. 11 It is an enlarged schematic diagram of part C in the structure shown in FIG. 10 . The card holder 100 is used for accommodating the customer identification card. The card holder 100 includes a bracket 120 , a connecting piece 140 and a detection elastic piece 160 . The connecting piece 140 and the detection elastic piece 160 are both disposed on the bracket 120 . The main difference between the card holder 100 of this embodiment and the card holder 100 of the above-mentioned embodiments is that when the customer identification card is not inserted into the card holder 100 , the detection elastic piece 160 and the connecting piece 140 are arranged at intervals, and when the customer identification card is inserted into the card holder 100 , the detection elastic piece 160 is electrically connected with the connector 140 . Whether there is a SIM card inserted into the card holder 100 can be determined by detecting the connection state between the elastic piece 160 and the connector 140 . The detection of the physical contact and separation of the elastic piece 160 and the connector 140 can accurately obtain whether the SIM card is inserted into the card holder 100 , so that the accuracy of detecting whether the SIM card is inserted into the card holder 100 is high.

It should be noted that, in the related art, a detection circuit connected to the SIM is arranged in the card holder. When the SIM card is not inserted into the card holder, the detection circuit is disconnected.

However, if the SIM card is not inserted into the card holder 100 or the SIM card is invalid, it cannot be detected effectively. This embodiment detects whether a SIM card is inserted into the card holder 100 by detecting the physical connection between the elastic sheet 160 and the connector 140 . When the SIM card is not inserted into the card holder 100, the detection spring 160 and the connector 140 are spaced apart, and the level of the detection spring 160 is not affected by the connector 140. When the SIM card is inserted into the card holder 100, the detection spring 160 is squeezed by the SIM card The detection elastic piece 160 is electrically connected to the connection piece 140 , and the level of the detection elastic piece 160 is influenced by the connection piece 140 . For example, when the SIM card is not inserted into the card holder 100, the detection spring 160 is spaced from the connector 140, and the level of the detection spring 160 is low. When the SIM card is inserted into the card holder 100, the detection spring 160 is squeezed by the SIM card. It abuts and is electrically connected to the connector 140, and changes the level of the detection dome 160 from a low level to a high level. Therefore, whether a SIM card is inserted can be identified and determined by detecting the level change of the dome 160, and the dome can be detected. The level change of 160 is determined by the physical connection or physical separation of the detection shrapnel 160 and the connector 140.

When the customer identification card is not inserted into the card holder 100 , the blocking portion 144 is separated from the connecting member 140 . When the customer identification card is inserted into the card holder 100 , the detection elastic piece 160 abuts against the blocking portion 144 and is electrically connected. The blocking portion 144 protruding from the connecting portion 142 can abut the detection elastic piece 160 , so as to abut and electrically connect with the detection elastic piece 160 . It should be noted that, when the customer identification card is inserted into the card holder 100, the detection elastic piece 160 is elastically deformed by the SIM card and abuts against the blocking portion 144. When the customer identification card is pulled out from the card holder 100, the detection elastic piece 160 returns The bomb is separated from the blocking portion 144 .

When the customer identification card is not inserted into the card holder 100 , the elastic portion 164 is spaced from the blocking portion 144 . When the customer identification card is inserted into the card holder 100 , the elastic portion 164 is elastically deformed and abuts against the blocking portion 144 . The detection elastic piece 160 may be a metal elastic piece, the material of the elastic portion 164 is a metal material, and the elastic portion 164 of the metal material is both elastic and conductive. The elastic portion 164 is connected to the side plate 124 through the fixing portion 162. The elastic portion 164 is a free end, and the elastic portion 164 is easily squeezed by the SIM to be separated from the blocking portion 144. When the SIM card is pulled out, the elastic portion 164 can be easily restored due to its elastic restoring force. the rebound, so as to be separated from the blocking part 144 .
