The auxiliary copper leakage area 613 is arranged on the fourth surface 616, and is used to electrically connect the first circuit board 60 with the pen clip 30. When the first circuit board 60 is installed on the pen clip 30, the fourth surface 616 faces the inner wall 312 of the pen clip 30, and the auxiliary copper leakage area 613 faces the inner wall 312. When static electricity is generated in the pen clip 30, the current in the pen clip 30 can break through the air between the inner wall 312 and the auxiliary copper leakage area 613, so that the pen clip 30 is electrically connected with the auxiliary copper leakage area 613, thereby realizing direct transmission of the static electricity of the pen clip 30 to the first circuit board 60, so as to improve the static electricity transmission efficiency.

The first side surface 701, the second side surface 702, the third side surface 703, and the fourth side surface 704 are connected end to end and are connected between the first surface 705 and the second surface 706. The first side surface 701 and the third side surface 703 are parallel and oppositely arranged, the second side surface 702 and the fourth side surface 704 are parallel and oppositely arranged, and the second side surface 702 and the fourth side surface 704 are connected between the first side surface 701 and the third side surface 703.

[0085] The reinforcing plate 70 is laminated on the surface of the fixing portion 61 of the first circuit board 60 and is fixedly connected with the fixing portion 61.

In the embodiment, by arranging the fixing member in the first through hole 611 and the second through hole 72, the stability of the connection between the reinforcing plate 70 and the first circuit board 60 can be further improved.

[0087] It should be noted that, in some embodiments, the first through hole 611 and the second through hole 72 can also be unnecessary, especially when the conductive member 90 can provide sufficient bonding strength between the reinforcing plate 70 and the fixed portion 61 of the first circuit board 60, the first through hole 611 and the second through hole 72 can not be arranged.

[0088] As shown in Figure 7 , the conductive assembly 1 further comprises a conductive member 90. In the embodiment, the conductive member 90 is conductive glue. In other embodiments, the conductive member 90 can also be other conductive adhesives. The conductive member 90 is arranged between the reinforcing plate 70 and the fixed portion 61 of the first circuit board 60, and adheres the second surface 706 and the third surface 615, and the conductive member 90 is electrically connected with the reinforcing plate 70 and the first circuit board 60. In the embodiment, the conductive member 90 is in contact with and electrically connected with the copper-free area 614 arranged on the third surface 615. The current on the reinforcing plate 70 is first transmitted to the conductive member 90, and then transmitted to the copper-free area 614 of the first circuit board 60 by the conductive member 90, so as to realize the electrical connection between the reinforcing plate 70 and the first circuit board 60.

[0089] Please refer to Figures 8 to 10 , Figure 9 is Figure 3 the partial cross-sectional view of the hand-writing pen 100 shown in Figure 10 is Figure 8 the partial structure schematic view of the conductive assembly 1 from another perspective.

[0090] The conductive assembly 1 further comprises a connecting member 80. The conductive assembly 1 is installed in the shell 10, and the charging interface 50, the reinforcing plate 70 and the connecting member 80 are all located in the accommodating cavity 301 of the pen holder 30. The connecting member 80 is located between the reinforcing plate 70 and the mounting portion 31 of the pen holder 30, and is fixedly connected and electrically connected with the reinforcing plate 70 and the inner wall 312 of the mounting portion 31. The static electricity on the pen holder 30 can be transmitted to the reinforcing plate 70 through the connecting member 80, and then transmitted to the first circuit board 60, so as to realize the static electricity leading-out of the pen holder 30.

[0091] In this embodiment, the connector 80 is an "L"-shaped metal sheet. For example, the connector 80 can be a steel sheet, copper sheet, or iron sheet. The connector 80 includes a first connector 81 and a second connector 82. The first connector 81 and the second connector 82 are connected at an angle. In this embodiment, the angle between the first connector 81 and the second connector 82 is 90 degrees. Of course, the angle between the first connector 81 and the second connector 82 can also be slightly greater than 90 degrees or slightly less than 90 degrees, as long as the angle between the first connector 81 and the second connector 82 is substantially the same as the angle between the first side surface 701 and the second side surface 702.

[0092] The connector 80 is fixed to the reinforcing plate 70. A first connector 81 is fixed to the first side 701 of the reinforcing plate 70, and a second connector 82 is fixed to the second side 702. Both the first connector 81 and the second connector 82 are electrically connected to the reinforcing plate 70. In this embodiment, the width of the connector 80 is greater than the thickness of the reinforcing plate 70. That is, when the connector 80 is fixed to the reinforcing plate 70, the connector 80 protrudes from the reinforcing plate 70 in the thickness direction, and the dimension of the connector 80 along the Z-direction is greater than the dimension of the reinforcing plate 70 along the Z-direction. In this embodiment, by making the width of the connector 80 greater than the thickness of the reinforcing plate 70, the contact area between the connector 80 and the reinforcing plate 70 can be increased, improving the stability of the connection between the connector 80 and the reinforcing plate 70. In other embodiments, the width of the connector 80 may be the same as the thickness of the reinforcing plate 70, or slightly less than the thickness of the reinforcing plate 70.

[0093] like Figure 9 As shown, the connector 80 and the extension 62 of the first circuit board 60 are offset in the Y direction. That is, the orthographic projection of the connector 80 along the X direction on the second side 702 and the orthographic projection of the extension 62 along the X direction on the second side 702 are offset and have no overlap, so as to avoid the connector 80 and the extension 62 from contacting each other and affecting the signal transmission performance of the first circuit board 60.

[0094] In the embodiment, the connecting piece 80 is fixedly connected and electrically connected with the reinforcing plate 70 by welding. In other embodiments, the connecting piece 80 can be fixedly connected and electrically connected with the reinforcing plate 70 by clamping, bonding or other manners. In the actual welding process, an auxiliary steel sheet (not shown in the figure) can be fixedly connected between the first connecting body 81 and the second connecting body 82, the auxiliary steel sheet extends away from the second connecting body 82, and the auxiliary steel sheet is arranged in parallel with the second connecting body 82. First, the reinforcing plate 70 is installed in the accommodating cavity 301 of the pen clip 30, and the pen clip 30 and the reinforcing plate 70 are fixed by using a clamp to position the pen clip 30 and the reinforcing plate 70. Then, the connecting piece 80 with the auxiliary steel sheet fixed thereon is moved towards the reinforcing plate 70, so that the first side surface 701 is in contact with the first connecting body 81, and the second side surface 702 is in contact with the second connecting body 82. Then, the auxiliary steel sheet is fixed on a mold to fix and position the connecting piece 80. Then, the first side surface 701 and the first connecting body 81 are welded to connect the first side surface 701 and the first connecting body 81 by welding material, and the second side surface 702 and the second connecting body 82 are welded to connect the second side surface 702 and the second connecting body 82 by welding material, so as to realize the fixed connection and electrical connection between the connecting body and the reinforcing plate 70. The first connecting body 81 and the inner wall 312 are welded, and the second connecting body 82 and the inner wall 312 are welded, so that the connecting piece 80 is fixedly connected and electrically connected with the inner wall 312 of the mounting portion 31 of the pen clip 30. After the welding is completed, the auxiliary steel sheet can be removed by cutting.

The first avoiding notch 612 and the second avoiding notch 71 limit the limiting step 323, which can prevent the pen clip 30 from being pulled out of the opening of the shell 10, thereby improving the stability of the installation of the pen clip 30, and improving the stability of the connection between the pen clip 30 and the connecting piece 80.

[0097] The static electricity generated by the pen clip 30 in use is transmitted to the connecting piece 80 through the inner wall 312 of the mounting part 31, and then transmitted to the reinforcing plate 70 by the first connecting body 81 and the second connecting body 82 at the same time, and then transmitted to the fixed part 61 of the first circuit board 60 by the reinforcing plate 70 through the conductive piece, and then transmitted to the second circuit board of the control module from the fixed part 61 and the extension part 62, and then transmitted to the grounding point of the second circuit board, so as to realize the discharge of the static electricity generated by the pen clip 30 to the outside through the first circuit board 60.

[0098] In the embodiment, by setting the connecting piece 80 and the reinforcing plate 70 of metal material, and making the pen clip 30 and the first circuit board 60 conductive through the connecting piece 80 and the reinforcing plate 70, the static electricity generated by the pen clip 30 can be discharged to the outside through the first circuit board 60, so that the signal disconnection between the stylus 100 and the electronic device 210 due to static electricity failure can be avoided, the stability of the signal connection between the stylus 100 and the electronic device 210 is improved, and then the smoothness of the stylus 100 in use is improved, and the user's use experience is improved.

The two elastic arms in the embodiment are a first elastic arm 74 and a second elastic arm 75. The main body 73 is a solid plate structure. The main body 73 includes a first side edge 731 and a second side edge 732, which are oppositely arranged. The first elastic arm 74 is substantially "L" shaped. The first elastic arm 74 includes a first connecting portion 741, a first elastic connecting portion 742, and a first protrusion 743. One end of the first connecting portion 741 is fixedly connected with the first side edge 731, and the other end is fixedly connected with the first elastic connecting portion 742. The first elastic connecting portion 742 is arranged in a spaced manner with the first side edge 731, and a gap is formed between the first elastic connecting portion 742 and the first side edge 731. The first protrusion 743 is fixed to one end of the first elastic connecting portion 742 away from the first connecting portion 741, and the first protrusion 743 protrudes towards the direction away from the first side edge 731. In a natural state, the first elastic connecting portion 742 is arranged in parallel with the X direction. When the first elastic connecting portion 742 is subjected to a force towards the first side edge 731, the first elastic connecting portion 742 inclines towards the first side edge 731 and deforms.

[0113] In the embodiment, the second elastic arm 75 has the same structure as the first elastic arm 74.

In the embodiment, the reinforcing plate 70 makes the pen clip 30 conductive with the first circuit board 60, the static electricity generated by the pen clip 30 can be conducted to the outside through the first circuit board 60, so that the signal connection between the stylus 100 and the electronic device 210 due to static electricity failure can be avoided, the stability of the signal connection between the stylus 100 and the electronic device 210 is improved, the smoothness of the stylus 100 in use is improved, and the user experience is improved.
