Embodiment
The utility model provides a kind of smart card USB interface cover, is applied to have the smart card of usb circuit, and the smart card with usb circuit is effectively used, and realizes high-speed transmission advantage.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to Fig. 1, this figure is a kind of execution mode structural representation of the utility model.
The utility model smart card USB interface cover comprises the cutting ferrule 1 that is used to place described smart card, is fixedly mounted on the deck 3 on the cutting ferrule 1, on deck 3, be provided with and the corresponding contact 31 of smart card contact, and the USB that is electrically connected with the contact 31 of deck 32.
Smart card width with usb circuit can be standard intelligent card width 53.96mm, and the interior well width of cutting ferrule 1 is certain width value between the 53.5mm to 56.5mm, and need satisfy the condition of the interior well width of cutting ferrule 1 greater than this smart card width simultaneously.The smart card that has usb circuit like this could be put into cutting ferrule 1 smoothly.Deck 3 is fixedly mounted on the cutting ferrule 1, and 8 contacts 31 are set on the deck 3, divides two rows to arrange 4 contacts of every row.When smart card inserts cutting ferrule 1, the corresponding contact in 8 contacts on 8 contacts 31 of deck 3 and the smart card.USB 2 is connected with the contact 31 of deck 3, and when USB 2 links to each other with the computer USB interface, this smart card just can be realized the communication with computer.
Referring to Fig. 2, this figure is second kind of execution mode structural representation of the utility model.
The smart card USB interface cover of present embodiment is to shown in Figure 1 similar, and difference is that cutting ferrule 1 interior well width is certain width value between the 14.5mm to 17.5mm.This smart card USB interface cover is the small intelligent card that has usb circuit in order to adapt to, and the width of this small intelligent card is the width 15 ± 0.1mm of standard intelligent card.The interior well width of cutting ferrule 1 can be certain width value between the 14.5mm to 17.5mm, and need satisfy the condition of the interior well width of cutting ferrule 1 greater than this small intelligent card width simultaneously.This smart card just can be put into cutting ferrule 1 smoothly like this.
The interior well width of the utility model cutting ferrule 1 can also be other sizes, cooperates the use of the smart card of different in width.The interior well width of cutting ferrule 1 matches with the width dimensions of smart card, and size need satisfy smart card can insert condition in the cutting ferrule smoothly.Certainly also to satisfy be fixed on cutting ferrule 1 upper blocking seat 3 contact 31 will with the corresponding condition of inserting in the cutting ferrule 1 of smart card contact.Make like this deck 38 contacts 31 just with smart card on the corresponding contact in 8 contacts.
Referring to Fig. 3, this figure is the enlarged diagram of the utility model deck part.
