Card connector

The present invention is a connector, especially a connector for a wafer card, which maintains the stability of electrical continuity of the switch terminals when the wafer card is used.

According to the ever-changing technology, the digitalization of technology and the rapid development of the information industry, the demand for various digital electronic products (mobile phones, digital cameras, etc.) is increasing day by day. Relatively, the various storage media are rapidly developing, according to different needs. Storage media also has a variety of different designs. In order to increase the storage energy or expand the performance of digital products, various electronic products usually have plug-and-play electronic cards, especially memory cards because of the fast reading and storage speed, and fast The advantages of extraction and replacement, and often used in a large number of mobile communication devices, digital audio and video equipment, digital cameras, etc., therefore, the connector for inserting the electronic card into the electronic product is widely used, through the card connector To achieve electrical connection and data transmission between the electronic card and the electronic product.

For example, it has become a general daily behavior to store image data taken by a digital camera or music data downloaded from a music distribution website on a memory card of a recording medium and apply it to various electronic machines. Memory cards sold on the market are available in a variety of sizes or configurations. The memory card used in some electronic devices is a memory card according to a specific specification, for example, only limited to the type of connector used for the electronic device. For this reason, sometimes different memory cards cannot be directly connected to an electronic device. So developed a card transfer The card adapter is an electronic device for connecting a memory card and an electronic device to use a memory card of a specific specification, and uses a memory card of a different specification.

Generally, an electrical connector for electrically connecting an electronic card is usually provided with a detecting switch to determine whether the electronic card is inserted. The existing detecting switch is usually composed of a fixed terminal and an elastic terminal. The fixed terminal and the elastic terminal are fixed to the insulating case, wherein the elastic terminal portion extends into the slot of the electrical connector, and is pushed by the electronic card into the slot. The elastic terminal changes the contact state between the elastic terminal and the fixed terminal, and can detect whether the electronic card is inserted into the slot. The elastic terminal and the fixed terminal may be in contact with each other when the electronic card is not inserted into the slot, and are called normally closed switches, or are separated from each other, and are called normally open switches. The normally closed switch separates the elastic terminal from the fixed terminal when the electronic card is inserted into the slot, and the normally open switch contacts the fixed terminal with the fixed terminal when the electronic card is inserted into the slot.
