A case structure for an electronic device includes a first conductive layer, a conductive housing, and a surface treatment layer. The first conductive layer has a taper protrusion. The conductive housing is disposed at one side of the first conductive layer, and a narrow end of the taper protrusion faces the conductive housing. The surface treatment layer is disposed between the taper protrusion and the second conductive layer.

Case structure

An electronic device includes a case, a board module, and an electrostatic discharging module. The case has a conductive area. The board module is disposed in the case and has a ground end. The electrostatic discharging module is disposed on the case. Besides, the electrostatic discharging module includes a first discharging element and a second discharging element. The first discharging element is electrically connected to the ground end, and the second discharging element is electrically connected to the conductive area. There exists a gap between the first discharging element and the second discharging element, so that leak current generated by the board module can be prevented from being transmitted to the case, and that an electrostatic charge can be transmitted from the case to the ground end.

Power limitation transformer circuit structure of power supply

A heat-radiating structure co-usable with heat-radiating window of a housing of an electronic appliance, including a housing having a rigid wall defining an interior space. At least one side of the rigid wall is formed with an opening or a heat-radiating window and multiple fin units each having a free end and a connecting end connecting with an adjacent fin unit. The fin units are serially arranged to form a fin construction. The adjacent fin units define a pitch or exhaustion gap meeting the safety standard regulated by IEC. The heat-radiating structure further has a fan unit having a connecting section connected with the connecting ends of the fin construction. The fan unit is formed with a flow way for conducting the heat generated in the housing toward the fin construction and dissipated out from the opening or heat-radiating window through the pitch or exhaustion gap.
