Touch panel capable of efficiently blocking electromagnetic waves

Abstract

The invention relates to the technical field of touch panels, in particular to a touch panel capable of efficiently blocking electromagnetic waves. The touch panel includes a workbench, wherein a mounting groove is formed in the middle of the upper end surface of the workbench; a heat dissipation bottom plate is arranged in the middle of the lower end face of the workbench; and jacks are formed infour edge corners of the lower end surface of the workbench. The touch panel has the beneficial effects that the heat dissipation bottom plate and a cooling fan are arranged at the lower end of the workbench, and then an inner cavity of the mounting groove is cooled in time, so that smooth dissipation of internal heat is ensured, and the use environment of electrical parts is protected; accordingto the touch circuit board, the metal wire mesh of a rectangular frame structure in linear distribution is matched with the wave absorbing layer, so that the touch circuit board is blocked in all directions, and the electromagnetic wave blocking effect is enhanced, and the operation accuracy of the touch circuit is improved; through cooperation of the insertion rods and the conductive supportingrods, winding of the wires is used for replacing a shielding metal net, and rapid installation of the blocking device is achieved.
