Portable electronic device

The invention relates to a portable electronic device, which belongs to the electronic field. The portable electronic device mainly comprises an electronic module, and a filling compound slidably arranged on the electronic module. At least one electronic module metal conductor group is arranged at one side of the electronic module, and comprises a first metal conductor group, a second metal conductor group, a third metal conductor group and a fourth metal conductor group. The filling compound is provided thereon with a fifth metal conductor group, a sixth metal conductor group, a seventh metal conductor group and an eighth metal conductor group corresponding to and matched with the first, second, third and fourth metal conductor groups. Therefore, when the filling compound horizontally slides on the electronic module, the first, second, third and fourth metal conductor groups form mutual friction with the fifth, sixth, seventh and eighth metal conductor groups to thereby conduct, namely, the metal conductor groups will not be oxidized through friction, and the metal conductor groups are electrically conducted without welding by adopting slidable assembly technique, so as to prevent generation of unqualified products.
