Abstract

The invention discloses a mobile communication device and a detecting method of subscriber identity module (SIM) card hotplug. The mobile communication device comprises a baseband chip, an SIM card connector and a clamping buckle, wherein the SIM card connector is in electric connection with the baseband chip, the clamping buckle is arranged on a position of an inlet of an SIM card inserting groove of the SIM card connector and used for being covered on the inlet of the SIM card inserting groove. The clamping buckle is provided with a first detecting assembly which is in electric connection with a first external interrupt pin and used for detecting opening and closing actions of the clamping buckle, and the SIM card connector is provided with a second detecting assembly which is in electric connection with a baseband chip second external interrupt pin and used for detecting plugging in and pulling out states of an SIM card. The mobile communication device and the detecting method of SIM card hotplug can effectively detect SIM card hotplug actions by a user, and timely protect the SIM card and the mobile communication device.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a mobile communication equipment and a detection method for hot plugging of a SIM card. Background technique [0002] At present, mobile communication devices are developing towards thinner and lighter, especially smart phones. Smartphones with large screens, large battery capacity, and thin and light bodies are easy to be welcomed by users. Among them, the thin and light mobile phones generally have the battery of the mobile phone designed to be non-removable. When the smart phone is working, if the user suddenly pulls out the SIM card, the SIM card may be damaged, thereby affecting the user's use. [0003] Therefore, it is necessary to provide a mobile communication device and a detection method for hot plugging of a SIM card to solve the above problems. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a detec...
