Abstract
The utility model discloses a kind of composite card, it comprises a chip carrier, this chip carrier is provided with a card assembly, week edge along this card assembly on this chip carrier is provided with the cut channel of being convenient to this card assembly taking-up, this card assembly comprises a little sim card, along week of this little sim card along being arranged with successively the cutting ferrule of some different size sizes.Simple in structure, reasonable in design, can need to select the cutting ferrule of different size to coordinate the use of little sim card according to using, thereby not need extra cutting mobile phone sim card can be applied on different mobile phones.
Description
Technical field
The utility model relates to cellphone subscriber's identification card, particularly a kind of composite card.
Background technology
Sim card is also called Subscriber Identity Module, and it is actually an intelligent cards that includes large scale integrated circuit, is used for registered user's significant data and information.The most important function of sim card is to carry out authentication and encryption.When user moves to new region when dialing or receiving calls, switch all will carry out authentication to user, take and determines whether as validated user.At this moment, sim card and switch utilize authentication arithmetic simultaneously, and KI and 8 random digits are calculated, and result of calculation is identical, and sim card admitted, otherwise sim card is rejected, and user cannot call out.Sim card also can utilize cryptographic algorithm, and speech is encrypted, and prevents eavesdropping.
Fast development due to smart mobile phone, the extensive popularization and application of smart mobile phones such as iphone mobile phone, Samsung mobile phone, cause conventional standard specification sim card can not meet the needs of use, in the time of conventional criteria sim will being snapped fitted in the Samsung mobile phone of iphone mobile phone or certain model, to first standard specification sim card be cut out, otherwise install not enter.But standard sim card is cut out, needed the user of sim card additionally to increase again expense, and the words of careless manipulation easily damage sim card, and incured loss through delay the use of sim card.
Summary of the invention
The purpose of this utility model is, a kind of composite card is provided, simple in structure, reasonable in design, can need to select the cutting ferrule of different size to coordinate the use of little sim card according to using, thereby not need extra cutting mobile phone sim card can be applied on different mobile phones.
The technical scheme that the utility model adopted is for achieving the above object:
A kind of composite card, it comprises a chip carrier, this chip carrier is provided with a card assembly, week edge along this card assembly on this chip carrier is provided with the cut channel of being convenient to this card assembly taking-up, this card assembly comprises a little sim card, along week of this little sim card along being arranged with successively the cutting ferrule of some different size sizes.In use, can directly use little sim card, also can coordinate cutting ferrule to use on little sim card.
The length of described little sim card is 12.3mm, and width is 8.8mm.Can directly use this little sim card, not needing length is that the standard specification sim card that 25mm, width are 15mm carries out cutting.
Week edge along this little sim card is arranged with the cutting ferrule of two different size sizes successively, and these two cutting ferrules are respectively the first cutting ferrule and the second cutting ferrule.
The length of described the first cutting ferrule is 15mm, and width is 12mm.When putting the first cutting ferrule, be equivalent to the sim card that uses a length to be 12mm for 15mm, width.
The length of described the second cutting ferrule is 25mm, and width is 15mm.When packaging again place cutting ferrule on the first cutting ferrule, be equivalent to the sim card that uses a length to be 15mm for 25mm, width.
This little sim card, the first cutting ferrule corner corresponding with the second cutting ferrule are provided with inclined-plane, are convenient to be inserted in mobile phone.
Its excess-three corner of this little sim card, the first cutting ferrule and the second cutting ferrule is provided with fillet, is convenient to be inserted in mobile phone.
The beneficial effects of the utility model are: simple in structure, reasonable in design, and can need to select the cutting ferrule of different size to coordinate the use of little sim card according to using, thereby not need extra cutting mobile phone sim card can be applied on different mobile phones.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of composite card of the utility model, it comprises a chip carrier 1, this chip carrier 1 is provided with a card assembly 2, week edge along this card assembly 2 on this chip carrier 1 is provided with the cut channel of being convenient to 2 taking-ups of this card assembly, this card assembly 2 comprises a little sim card 21, along week of this little sim card 21 along being arranged with successively the cutting ferrule of some different size sizes.In use, can directly use little sim card 21, also can coordinate cutting ferrule to use on little sim card 21.
The length of described little sim card 21 is 12.3mm, and width is 8.8mm.Can directly use this little sim card 21, not needing length is that the standard specification sim card that 25mm, width are 15mm carries out cutting.
Week edge along this little sim card 21 is arranged with the cutting ferrule of two different size sizes successively, and these two cutting ferrules are respectively the first cutting ferrule 22 and the second cutting ferrule 23.
The length of described the first cutting ferrule 22 is 15mm, and width is 12mm.When putting the first cutting ferrule 22, be equivalent to the sim card that uses a length to be 12mm for 15mm, width.
The length of described the second cutting ferrule 23 is 25mm, and width is 15mm.When packaging again place cutting ferrule on the first cutting ferrule 22, be equivalent to the sim card that uses a length to be 15mm for 25mm, width.
This little sim card 21, the first cutting ferrule 22 and a corresponding corner of the second cutting ferrule 23 are provided with inclined-plane, are convenient to be inserted in mobile phone.
Its excess-three corner of this little sim card 21, the first cutting ferrule 22 and the second cutting ferrule 23 is provided with fillet, is convenient to be inserted in mobile phone.
Simple in structure, reasonable in design, can need to select the cutting ferrule of different size to coordinate the use of little sim card 21 according to using, thereby not need extra cutting mobile phone sim card can be applied on different mobile phones.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
