Description

Built-in card reader structure Technical Field The invention relates to the technical field of card readers, in particular to a built-in card reader structure. Background The card reader (CARDREADER) is a card reader device, and because of the large number of card types, the meaning coverage range of the card reader is relatively wide, the memory card is widely applied to smart phones and cameras, and in a broad sense, smart phones and cameras are also used as card readers, and the types of the stored cards are classified into CF card readers, SM card readers, PCMICA card readers, memory stick readers and the like, and also double-slot card readers can simultaneously use two or more kinds of cards, and along with the reverse development of electronic products such as mobile phones and the like towards non-detachable, the built-in card readers are also increasingly widely applied. At present, the card reader is used for fixing the card by using the elastic force generated by pressing and deforming the copper wire to fix the card, and the card can be quickly plugged in and pulled out by the fixing mode, but the copper sheet of the card and the copper wire of the card reader for fixing the card are worn along with the long-time plugging of the card, so that the service lives of the card reader and the card can be influenced.
