card connector

Abstract

The invention discloses a card connector. The card connector can be used for connecting at least two electronic cards in different size. The card connector comprises an insulating body which extends lengthwise, a plurality of conducting terminals which are fixed on the insulating body and a shielding casing which is fixed on the insulating body; the shielding casing and the insulating body form into insertion connection space; the card connector further comprises an elastic sheet which is fixed on the insulating body; the elastic sheet is provided with a guiding arm which extends into the insertion connection space in a protruding mode; the guiding arm can swing back and forth between a first position and a second position; the shielding casing is provided with an elastic arm; the guiding arm is ejected by a first protruding portion and small stable insertion connection space is provided when the guiding arm is arranged at the first position; when a large electronic card is inserted into the card connector, a second protruding portion of the elastic arm is ejected by the large electronic card, then the first protruding portion of the elastic arm and the guiding arm are separated, the guiding arm is in a free state, and large insertion connection space is provided. Compared with the existing card connector, the card connector is benefited to insertion connection of at least two electronic cards, the utilization is convenient, and manufacturing costs are reduced.

Description

【Technical field】 [0001] The invention relates to the electronic field, in particular to a card connector for inserting an electronic card. 【Background technique】 [0002] Mobile phones bring more convenience to people's lives. Usually, if a mobile phone wants to realize wireless signal transmission, it needs to install a SIM card on the mobile phone to realize the communication function. With the development of communication technology, the current SIM card has evolved to the second generation. MiniSIM card, third-generation MicroSIM card and fourth-generation NanoSIM card, the size of each electronic card is different, that is, the development trend towards miniaturization, for example, the length and width of MicroSIM card are 15x12mm, and the length and width of NanoSIM card are 12x9mm, nearly 30% area reduction. [0003] At present, mobile phones on the market can only insert one type of SIM card. If the manufacturer needs to change to the next type of SIM card, the el...

Problems solved by technology

[0003] At present, mobile phones on the market can only insert one type of SIM card. If the manufacturer needs to change to the next type of SIM card, the electronic card connector for inserting the SIM card needs to be changed at the same time. If the consumer updates to the next-generation electronic card, such as from Updating from 3G to 4G may require replacement of mobile phones, which will cause inconvenience to consumers

[0004] Furthermore, please refer to the Japanese patent patent No. 4536126 announced on June 25, 2010, which discloses a card connector with two different slots for different electronic cards to be plugged in, wherein one slot is for SIM Card plugging, another slot is for SD card plugging, and different slots are equipped with different conductive terminals, thus, the card connector of this existing structure has increased overall thickness, is unfavorable for the electronic card connector. Miniaturization is also not conducive to the ultra-thin development of electronic products. At the same time, different conductive terminals can only be plugged into one type of electronic card, which increases the manufacturing cost of electronic card connectors
