Description

card reader

technical field

The invention relates to an electrical connector, in particular to a card reader.

Background technique

The progress of modern science and technology also leads many electronic products to continuously innovate and progress, and enter the digital age. Therefore, digital technology products are constantly being introduced, such as digital TVs, digital audio, MP3, digital cameras, electronic dictionaries, PDAs or other electronic products. products, etc. In many digital products, the memory card is usually used to store, access data, update memory data, etc., and then the card reader reads or stores the data inside the memory card. However, in pursuit of ease of use , Easy to carry, many electrical products are designed to be light, thin, short, and small, and the internal components must be reduced in size, so it is necessary to design a smaller memory card power supply product for use.

At present, the memory cards on the market are roughly multimedia cards (MMC, Multi Media Card), compressed flash memory cards (CF, Compact Flash Card), smart media cards (SMC, Smart MediaCard), memory sticks (MS, Memory Stick) , Secure Digital Memory Card SD (Secure Digital Memory Card) and other specifications, and many memory cards with smaller size and larger capacity have been launched successively, such as Mini SD, Mini Flash Card (Trans Flash), Micro Security Digital memory card (MIRCO SD), etc.

In addition, the card reader is an interface between the memory card and the host computer, through the USB jack of the host computer, the card reader can transmit data, so that the card reader can be quickly read by the host computer by hot plugging. However, the current card readers on the market are relatively large in size, occupy too much space, and are inconvenient to carry because of their large size, which also increases the overall weight of the card reader, so that the card reader cannot be directly inserted into the USB jack of the host computer. In general, only an additional USB cable can be purchased for connection before transmission can be performed, which increases the cost of use and leads to more and more cables around the computer host.

Furthermore, the opening method of the USB jack on the casing of the general computer host is to follow the upper and lower docking grooves of the stacked electrical connector in the casing to correspond to the arrangement, so that the USB jacks are adjacent to and close to each other up and down on the surface of the casing. The storage device (such as flash drive, card reader, etc.) of the USB connection part is inserted into it, and when the general storage device is plugged into the upper USB jack, the lower USB jack is blocked by the volume of the storage device, causing the lower USB plug The problem that another storage device cannot be plugged into the USB hole, so that only one storage device can be plugged into two USB jacks at a time.

Therefore, how to try to solve the above-mentioned existing defects, and develop a kind of card reader with a USB connection part, which can be inserted into an external memory card, and is thin, light and small, is the direction for those skilled in the art to study and improve.
