Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram of the handheld communication device of the present invention, and FIG. 2 is a side view of the motherboard assembly of the present invention. In this embodiment, the handheld communication device 10 is illustrated as a smart phone, but the handheld communication device 10 is not limited thereto.

The handheld communication device 10 includes a display 11 , a housing 12 , an input device 15 , and a motherboard assembly 16 . The display 11 can be used to display incoming calls, input or receive information, and can watch pictures and videos, which is the same function as a general mobile phone, and the display 11 can also have a touch function. The shell 12 is used to protect the entire handheld communication device 10, and the input device 15 can provide the functions of dialing and inputting text. The motherboard assembly 16 includes a motherboard 14 and a metal component 13. action. In this embodiment, the metal inner and outer frame 151 of the input device 15 is the metal member 13, but the metal member 13 is not limited to this, for example, the outer frame 111 of the metal material surrounding the display 11, the metal material itself The casing 12 can also be a metal component 13 , or other metal brackets provided in the handheld communication device 10 to strengthen the overall structure.

The handheld communication device 10 includes a motherboard assembly 16, the motherboard assembly 16 includes a motherboard 14 and a metal member 13, the motherboard 14 includes a board body 143, a metal shrapnel 142, a grounding point G, and a communication assembly 141, wherein the metal shrapnel 142 is fixed On the board body 143 , the ground point G is connected to the metal dome 142 , so that the motherboard 14 is grounded through the metal dome 142 , and the communication component 141 is electrically connected to the board body 143 . The metal member 13 includes a body 131 and an insulating member 132 with a hole, and the metal member 13 is disposed above the main board 14 with a distance D apart from each other. The insulating member 132 with a hole is coupled to the body 131 and contacts the metal dome 142 , so that the metal dome 142 is close to the metal member 13 in an insulated manner, and there is a gap I between the metal dome and the metal member 13, and the insulating member 132 with pores fills the gap I, so that the metal dome 142 can The insulator 132 is floating with the body 131 of the metal member 13 .

It should be noted that the distance between the gap I and the thickness T of the insulating member 132 with pores can be equal, or the distance of the gap I can be less than or equal to 0.08mm, and the insulating member 132 with pores can be hot melt adhesive or double-sided Glue, but not limited thereto, and in this embodiment, the communication component 141 is an antenna.

When the metal member 13 accumulates too much static electricity or any external static signal hits the metal member 13, when the static voltage exceeds the critical value, the static electricity on the metal member 13 will use the tip discharge method to make the static electricity skip the hole with pores After the insulator 132 , it is transmitted to the metal shrapnel 142 , and finally the static electricity will be introduced into the ground point G on the motherboard 14 to achieve the purpose of static electricity protection. It should be noted that the present invention must select the insulator 132 with pores as the intermediate medium. Since the insulator 132 has pores, static electricity can pass through the insulator 132 through the pores.
