Description
[technical field]
The utility model relates to mobile communication equipment technical field, relates in particular to the smart mobile phone SIM card that is easy to test.
[background technology]
Along with developing rapidly of mobile communication cause, mobile phone has become the more and more indispensable instrument of many consumers daily life, and the Subscriber Identity Module (SIM card) being installed in mobile phone is the main part that realizes call.In the time that mobile phone is opened, mobile phone all will carry out data exchange with SIM card.While not having plug-in card, these signals can not be sent.SIM card is the abbreviation of (Subscriber Identity Module client identification module), and also referred to as subscriber identification card, smart card, GSM digital mobile telephone must be loaded onto this card and can use.It has stored digital mobile phone client's information on computer chip, and the contents such as the key of encryption and user's telephone directory can be differentiated for GSM network client identity, and voice messaging when client is conversed is encrypted.
SIM card is a chip card that microprocessor is housed, there are 5 modules its inside, and the corresponding function of each module: microprocessor CPU (8), program memory ROM (3～8kbit), working storage RAM (6～16kbit) data-carrier store EEPROM (128～256kbit) and serial communication unit, these 5 modules are identical with common IC-card packaged type after SIM card copper interface by rubber seal.
SIM card is dispatched from the factory before encapsulation, need to carry out sample testing to the performance of SIM card, ensure the quality of dispatching from the factory of SIM card, in traditional method of testing, because card body is less, need certain patience and gimmick that card is fit in corresponding tool, have inclination at plug-in card with in moving back card process, cause the scratch of FPC plate face, affect the quality of SIM card, be unfavorable for dispatching from the factory of product.
Therefore, be necessary to design a kind of SIM card that is easy to test.
[utility model content]
Fundamental purpose of the present utility model is to provide a kind of smart mobile phone SIM card that is easy to test, and it is a kind of smart mobile phone SIM card of convenient test.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of smart mobile phone SIM card that is easy to test, comprise the carrier of plasticizing plates structure, on described carrier, be fixed with master chip, its one end is provided with antenna storage tank, described antenna storage tank is embedded with LTCC antenna, described LTCC antenna is connected by a corresponding day wire pin with master chip, the other end of described carrier is connected with handle, described handle comprises integrated Handheld Division and the connecting portion being connected with described carrier, and the width of described Handheld Division is greater than the width of connecting portion.
Preferably, the length of described handle is 5cm.
Preferably, the width of described handle Handheld Division is 5mm, and the width of connecting portion is 2mm.
Preferably, the Handheld Division of described handle and connecting portion are rectangular-shaped.
Preferably, described LTCC antenna is the radio-frequency antenna of preparing based on LTCC technology.
Preferably, the frequency of operation of described master chip is 13.5MHz.
Compared with prior art, the beneficial effect that the utility model is easy to the smart mobile phone SIM card of test is: adopt LTCC technology integrated RF antenna, realized the miniaturization of antenna, improved the stability of antenna, strengthened the serviceable life of double-interface SIM card; Obviously improve the SIM card problem that sending and receiving signal is decayed after the mobile devices such as mobile phone under contactless state simultaneously; Adopt 13.5MHz, meet ISO14443 standard, with most rf terminal compatibility, without existing rf terminal is transformed; On card, handle is set, makes the plug-in card that staff can be freely in the process of test and move back card, effectively avoided the scratch of SIM card FPC plate face, ensured the quality of dispatching from the factory of SIM card; Its structural design is simple, easy to make, production cost is low, effectively reduces staff's test operation difficulty, has improved the accuracy of test.
[brief description of the drawings]
Fig. 1 is the structural representation that the utility model is easy to the smart mobile phone SIM card of test.
Fig. 2 is the structural representation of the utility model while being easy to the test of smart mobile phone SIM card of test.
[embodiment]
Please refer to shown in Fig. 1, a kind of smart mobile phone SIM card that is easy to test of the utility model, comprise the carrier 2 of plasticizing plates structure, on carrier, be fixed with master chip 3, its one end is provided with antenna storage tank 1, antenna storage tank 1 is embedded with LTCC (LTCC) antenna, LTCC (LTCC) antenna is connected by a corresponding day wire pin with master chip 3, the other end of carrier 2 is connected with handle 4, handle 4 comprises integrated Handheld Division 401 and the connecting portion 402 being connected with described carrier, the width of Handheld Division 401 is greater than the width of connecting portion 402.
The length of handle 4 is 5cm, neither can be oversize and easily fracture, can too shortly not cause the inconvenience of holding yet; The width of handle 4 Handheld Divisions is 5mm, and the width of connecting portion is 2mm, if the excessive material of easily wasting of the width of connecting portion, the too small requirement of strength that does not reach connection; Handheld Division 401 and the connecting portion 402 of handle 4 are rectangular-shaped; The radio-frequency antenna of LTCC (LTCC) antenna for preparing based on LTCC (LTCC) technology; The frequency of operation of master chip 3 is 13.5MHz.
When use, as shown in Figure 2, utilize in the direct card-inserted device 5 that the carrier part of SIM card is inserted into special fixture of handle 4 and test.
The utility model adopts LTCC (LTCC) technology integrated RF antenna, has realized the miniaturization of antenna, has improved the stability of antenna, has strengthened the serviceable life of double-interface SIM card; Obviously improve the SIM card problem that sending and receiving signal is decayed after the mobile devices such as mobile phone under contactless state simultaneously; Adopt 13.5MHz, meet ISO14443 standard, with most rf terminal compatibility, without existing rf terminal is transformed; On card, handle is set, makes the plug-in card that staff can be freely in the process of test and move back card, effectively avoided the scratch of SIM card FPC plate face, ensured the quality of dispatching from the factory of SIM card; Its structural design is simple, easy to make, production cost is low, effectively reduces staff's test operation difficulty, has improved the accuracy of test.
Below schematically the utility model and embodiment thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, in the situation that not departing from the utility model creation aim, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
