Chip card connector

Abstract

The invention discloses a chip card connector, which is suitable for being arranged on a circuit board having a power supply terminal and a grounded terminal and the chip card is provided with a plurality of power supply pads and a plurality of signal pads. The chip card connector comprises a body, a metal cap body, a first power supply pin, a second power supply pin, a third power supply pin, a detection pin and a plurality of signal pins. The body is provided with an accommodating groove, and the metal cap body is electrically connected with the grounded terminal and covers the body. On end of the first power supply pin is electrically connected with the power supply terminal. One end of the second power supply pin is used for coming into contact with one of the power supply pads; and one end of the third power supply pin is used for coming into contact with another one of the power supply pads. The detection pin is respectively electrically connected with the second power supply pin and the third power supply pin, and the signal pins are respectively used for coming into contact with the signal pads.

Description

technical field [0001] The invention relates to a connector, and in particular to a chip card connector. Background technique [0002] With the continuous advancement of science and technology in recent years, human life has become inseparable from various electronic products. Taking portable communication devices such as mobile phones as an example, the penetration rate of mobile phones is quite high nowadays, and almost every general consumer has a mobile phone. Some mobile phone users will have two or more door numbers at the same time for the needs of life and work, and the relevant data of each door number will be stored in a chip card, such as a Subscriber Identity Card (Subscriber Identity Card). Module card, SIM card). If the user wants to change the door number to communicate, he must first change the SIM card installed in the mobile phone before using another door number. [0003] At present, the general mobile phones on the market do not support the hot swappin...

AI Technical Summary

Problems solved by technology

In this way, a current loop will be generated between the power pin 150a and the signal pin 160a or 160b, resulting in a short circuit between the power pin 150a and the signal pin 160a or 160b

Similarly, removing the chip card 50 when the mobile phone is turned on will also cause the above-mentioned short circuit phenomenon, and then damage the chip card connector 100

[0006] Therefore, the design of the traditional chip card connector 100 cannot support the hot plugging of the chip card 50

The user must first turn off the electronic device before replacing the chip card 50, otherwise a short circuit will be caused, the electronic device will be damaged, and the data stored in the chip card 50 will also be lost.
