Abstract
The utility model provides an antenna for a non-contact interface of a plug-in intelligent card in the technical filed of wireless communication, which comprises the antenna, an interface/socket arranged on the antenna, and a connection wire connected with the interface/socket. Through the design of the detachable connection wire, the problems that the connection wire is easy to fracture and cannot be replaced, and the antenna and the connection wire are solidified into a whole and are not convenient to disassemble and use in the prior art can be effectively solved.
Description
Technical field
The utility model relates to a kind of device of wireless communication technology field, specifically is a kind of antenna for the use of plug-in type smart card noncontact interface.
Background technology
DI (Dual Interface) card is the abbreviation of double-interface IC card, and the DI card is that coil forms by the laminated chip of PVC (Polyvinyl chloride polymer, polyvinyl chloride), and based on single-chip, collection contact and non-contact interface are the card of one.The DI card has two operation interfaces, both can also can under situation separated by a distance, visit chip, carry out identical operations by the contact of the way of contact by RF-wise, the different standard of two basic points is followed in two cross sections respectively, and contact interface meets ISO/IEC7816; The noncontact interface meets ISO/IEC1443.
Find through retrieval prior art, Chinese patent literature CN2833904, open day 2006-11-01, put down in writing a kind of " being attached to the antenna module on plug-in type smart card surface ", antenna comprises base material, is fixed on aerial coil and first and second days wire pins on the base material first surface in this technology.Wherein base material comprises structure, first and second contacts on the second surface and first and second via holes that cooperate card module, the structural configuration of first and second contacts and cooperation card module is on the described base material position corresponding with the contact of plug-in type smart card, and wire pin was connected on first and second contacts by first and second via holes respectively in first and second days.A weak point of this technology is: aerial coil links to each other by connection handle with the structure that cooperates card module, and first and second days wire pins extend to first and second contacts on the second surface along described connection handle.In actual the use, cooperate card module to insert in the mobile phone draw-in groove and use, during taking-up attached to Subscriber Identity Modules such as SIM card, the user gets used to pinching described aerial coil portion Subscriber Identity Modules such as SIM card is extracted, connection handle is torn easily, causes the fracture of first and second connecting lines, and influence is used.
The utility model content
The utility model is at the prior art above shortcomings, a kind of antenna for the use of plug-in type smart card noncontact interface is provided, by the design of dismountable connecting line, solved effectively that antenna is solidified into an integral body with connecting line and then is inconvenient to dismantle the problem of use in the non-exchange and prior art of connecting line easy fracture.
The utility model is achieved through the following technical solutions, and the utility model comprises: antenna, be arranged at the plug receptacle on the antenna and be attached thereto the connecting line that connects.
Described antenna comprises: antenna loops, suction ripple layer and basalis, and wherein: antenna loops is encapsulated in inhales between ripple layer and the basalis, and antenna loops places the interior volume of inhaling ripple layer and basalis formation with the winding of square structure uniform ring.
One end of described connecting line and plug receptacle flexibly connect, and other end Pasting is on telecom intelligent card.
The utility model has solved the base material and the smart card that are loaded with antenna stack and has been solidified into an integral body, is inconvenient to dismantle the problem of using, and makes it not only to be convenient to connect but also be convenient to dismantle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional view of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As shown in Figure 1, the utility model comprises: antenna 1, be arranged at plug receptacle 2 and connecting line 3 on the antenna, wherein: an end of connecting line 3 and plug receptacle 2 flexibly connect, and the other end sticks on the telecom intelligent card.
As shown in Figure 2, described antenna 1 comprises: antenna loops 4, suction ripple layer 5 and basalis 6, wherein: antenna loops 4 is encapsulated in inhales between ripple layer 5 and the basalis 6, and antenna loops 4 places the interior volume of inhaling ripple layer 4 and basalis 5 formations with square structure or the winding of circular configuration uniform ring.
The thickness of described suction ripple layer 5 is 0.1～0.7mm, and this suction ripple layer 5 is made for anti-electromagnetic interference material, in order to filter extraneous interference signal.
Copper or the aluminum metal antenna of thin slice that described antenna loops 4 is square structure or circular configuration is in order to the induction outer signals.
Described connecting line 3 is for having the strip data wire of standard contact interface.
