Abstract

The embodiment of the invention discloses an anti-interference device, an SIM card connection device and electronic equipment, relates to the field of a mobile terminal and aims at solving the problemthat in the prior art, cost is relatively high and stability is relatively low in an SIM card anti-interference process. The anti-interference device comprises a grounding module and a filtering module. The grounding module is connected with a grounding terminal in an SIM card connector. The grounding module is connected with one end of the filtering module. The grounding module is used for transmitting a first interference signal to the filtering module when the first interference signal exists in the SIM card connector. The filtering module is used for receiving and filtering the first interference signal. The embodiment of the invention is used for realizing an SIM card anti-interference function in the mobile terminal.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of mobile terminals, in particular to an anti-interference device, a SIM card connection device and electronic equipment. Background technique [0002] With the continuous development of technology and the improvement of people's living standards, mobile terminals have become an important part of life. As the core of the mobile terminal, the working status of the SIM card will directly affect the user's operating experience. When the SIM card is interfered, there will be problems such as poor call signal or even call termination. Therefore, how to improve the signal interference between the SIM card and the mobile terminal has gradually received attention from people in the field. [0003] At present, in the prior art, in order to reduce the interference between the SIM card and the mobile terminal, a metal shielding sheet is usually set on the card slot of the SIM card connector to shiel...
