Description

Card connector with radiator

Technical Field

The present application relates to a card connector, and more particularly, to a card connector with a heat sink, which has a heat sink for dissipating heat generated by an insulating body, a shielding shell and a memory card inserted into the card connector. The waste heat generated by reading and writing the high-speed memory card in the card connector can be properly conducted to the outside of the card connector by the heat sink, thereby preventing the memory in the memory card from being damaged by high temperature.

Background

The memory card is a common detachable data storage device on portable electronic devices such as digital cameras, smart phones, notebook computers, tablet computers, and the like, and is mainly used for providing necessary or additional data storage space for the electronic devices. In order to read from and write to a memory card, the electronic device is usually provided with a card connector compatible with the memory card. In addition, there are also independent card connector devices in the market, which allow users to connect the card connector device to the electronic device through a connecting wire, so that the electronic device without the built-in card connector can connect to the memory card through the card connector device to access the internal data of the memory card.

Please refer to the new patent No. M405018 in taiwan, which discloses a card reader, comprising: a housing, wherein two ends of the housing are respectively provided with a first housing part and a second housing part, the first housing part provides a card insertion space, the first housing part is provided with a set of interfaces and a connection end at the outer edge of the set of interfaces, the second housing part is provided with a Universal Serial Bus (USB) socket; a card reader includes a supporting board and a card insertion head at one end of the supporting board, the card insertion head is provided with a first edge, a second edge and a card insertion opening located in the second edge and opened outward.

In order to meet the increasing demand, memory cards are being developed to increase capacity, increase access speed, and maintain their original size. However, as the capacity and access speed of memory cards have increased, a problem associated with the memory cards is the large amount of waste heat generated during operation. However, the card reader disclosed in the above-mentioned new patent No. M405018 does not have any heat dissipation device to dissipate heat of the card reader itself and the memory card therein, so that when the card reader is applied to the high-speed memory card, waste heat generated during the operation of the high-speed memory card will be accumulated in the memory card itself and the card reader, and the memory card itself will be damaged or destroyed due to high temperature, which results in the risk of losing the data stored therein.
