[0002] The electromagnetic pen is a contour pen, generally used to replace fingers to operate the screen of mobile phones, tablet computers and other products. It is an auxiliary writing tool for electromagnetic induction touch panels. The electromagnetic pen uses electromagnetic touch technology to record the electronic trajectory of the pen while writing on paper. The electronic trajectory can record the writing process and content. Electromagnetic pens can be divided into two types: rechargeable electromagnetic pens and passive electromagnetic pens. Rechargeable electromagnetic pens require battery power, while passive electromagnetic pens do not require battery power.

[0003] When the battery of the electromagnetic pen is exhausted, a DC power supply can be obtained from the interface to charge the internal battery. However, the interface of the traditional electromagnetic pen has no protection and is directly exposed to the outside world, which is prone to moisture infiltration due to human or external conditions.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a rechargeable electromagnetic pen with anti-interface water seepage is proposed. Utility Model Content
