Electronic device of board protection mechanism

An electronic device of a board protection mechanism, comprising:

• a substrate, comprising a first surface and a second surface, wherein the first surface comprises a substrate protection area, and the second surface comprises an electronic element area;
• a first shell, located at the first surface of the substrate;
• a first protection area, located between the first surface of the substrate and the first shell, comprising:
• an operation board, located at the first shell, wherein the operation board is in contact with the substrate protection area, and when the operation board is not in contact with the substrate protection area, a signal loop of a loop protection program is driven to be broken or short-circuited;
• a mesh board, located between the operation board and the substrate protection area, wherein the mesh board is in contact with the substrate protection area, and when the mesh board is not in contact with the substrate protection area, the signal loop of the loop protection program is driven to be broken or short-circuited;
• a detection contact, located at a surface of the mesh board and comprising a first contact, a second contact, and a third contact separated from each other;
• a contact portion, located at the other surface of the mesh board and comprising a fourth connection point, a fifth connection point, a sixth connection point, and a second ground connection point;
• and
• a plurality of contact through holes, located at the mesh board and connected to the first contact and the fifth connection point, the second contact and the sixth connection point, and the third contact and the second ground connection point;
• a second shell, located at the second surface of the substrate and combined with the first shell, wherein the second shell comprises a groove and a feed inlet that are connected, the groove corresponds to the electronic element area, and the feed inlet corresponds to an outer side of the electronic element area;
• a second protection area, located at the groove of the second shell, wherein the second protection area comprises a wire mesh, surrounding the electronic element area and electrically connected to the substrate;
• and
• an adhesive piece, filled into the feed inlet to cover the groove, wherein the adhesive piece is fixed to the first shell, the second shell, the wire mesh, and the electronic element area, and when the first shell or the second shell is intruded or damaged by an external force, the adhesive piece and the wire mesh are touched to drive the signal loop of the loop protection program to be broken or short-circuited.
