[0030] The negative spring of the existing electronic stylus is welded on the PCB board. When it is installed into the pen tube together with the semi-finished internal bracket, the negative spring contacts the conductive part of the pen tube at a single point, and is connected to the pen tube to form a circuit, so that the whole pen can work. Since the negative spring of the electronic stylus is in single-point contact with the conductive part of the pen tube, when the electronic stylus is hit by external force, the contact will be unstable, resulting in the spring breaking, which will cause the electronic stylus to freeze.
[0031] To this end, the utility model proposes an anti-touch-off structure for an electronic touch pen, which is intended to enhance the reliability of the contact between the electrical spring and the conductive part of the pen tube 30 .
[0032] Reference Figures 1 to 6 , Figure 1 It is a structural schematic diagram of an embodiment of the anti-touch-off structure for an electronic touch pen of the utility model; Figure 2 This is a schematic diagram of the assembly of the inner mounting shell of the utility model in the plug-in portion 21; Figure 3 It is a schematic diagram of assembling the negative electrode connecting piece of the utility model on the inner mounting shell; Figure 4 This is a schematic structural diagram of the first half shell of the anti-touch-break structure for the electronic touch pen of the utility model; Figure 5 This is a schematic diagram of the structure of the anti-break structure electrical connection sheet for the electronic touch pen of the utility model; Figure 6 The utility model is a schematic diagram of the assembly of the electrical contacts of the anti-break structure for the electronic touch pen.
[0033] In the embodiment of the utility model, the electronic touch pen anti-touch structure includes a pen tip 20, an inner mounting shell 10 and a pen tube 30. Figures 1 to 6 As shown, the pen tip 20 includes an exposed portion 22 and a plug-in portion 21, an inner mounting shell 10 is inserted in the plug-in portion 21, a PCB board 13 is arranged in the inner mounting shell 10, an electric spring 14 connected to the PCB board 13 is attached to the outer periphery of the inner mounting shell 10, and a plurality of electric contacts 144 are protruded from the electric spring 14, a mounting opening for inserting the plug-in portion 21 is opened at one end of the pen tube 30, and a conductive portion is provided on the shell of the pen tube 30. When the inner mounting shell 10 is inserted into the plug-in portion 21, the pen tip 20 is inserted into the pen tube 30 from the mounting opening, so that the plurality of electric contacts 144 abut against the conductive portion.
[0034] In the present embodiment, the electrical contact 144 protrudes from the electrical spring 14, and the number of the electrical contact 144 is selected to be two, and they are integrally arranged with the electrical spring 14. The material of the electrical spring 14 is selected to be elastic nickel-plated stainless steel, and the shell of the pen tube 30 is made of aluminum alloy, so the conductive part is the pen tube 30 itself. Of course, in other embodiments, the shell of the pen tube 30 can also be made of insulating material, and a notch is penetrated through the outer periphery of the pen tube 30 for installing the conductive part. The conductive part is made of conductive material, so that only a small section of the conductive part is required to achieve connection with the electrical contact 144. When the inner mounting shell 10 with the PCB board 13 and the electrical spring 14 installed is installed to the end of the plug-in part 21 of the pen nozzle 20, the inner mounting shell 10 is inserted into the mounting opening of the pen tube 30 along with the plug-in part 21 of the pen nozzle 20, and the electrical contact 144 located on the inner mounting shell 10 abuts against the conductive part, so that the pen tube 30 and the PCB board 13 are electrically connected.
[0035] The technical solution of the utility model adopts a method of setting a plurality of power contact points 144 on the power spring piece 14. When the inner mounting shell 10 is first installed and fixed through the pen tip 20, and then the inner mounting shell 10 is installed to the pen tube 30 along with the pen tip 20, the plurality of power spring pieces 14 can be inserted into the pen tube 30 along with the inner mounting shell 10, and abut against the conductive part of the pen tube 30, and conduct with the pen tube 30 to form a power supply circuit. The power spring piece 14 is installed and fixed by inserting the inner mounting shell 10 fixed on the pen tip 20. After the pen tip 20 and the pen tube 30 are installed and fixed, the power spring piece 14 is less likely to shift than the pen tube 30. Compared with the traditional design of only setting a single power contact point 144, the reliability of contact with the conductive part of the pen tube 30 can be enhanced by using the plurality of power contact points 144. When the electronic touch pen is impacted by external force, the power spring piece 14 will not be disconnected from the conductive part.
[0036] Further, the electrical connection spring 14 includes a connection portion 141. Figure 3 , Figure 5 As shown, one end of the connecting portion 141 is bent along the outer circumference of the inner mounting shell 10 to form an electrical connection portion 142, and the electrical connection portion 142 is electrically connected to the PCB board 13. The other end of the connecting portion 141 is forked to form two contact portions 143 on both sides of the other end of the connecting portion 141, and two electrical contacts 144 are provided and are arranged one-to-one on the contact portion 143.
[0037] In this embodiment, the connecting portion 141 is bent along the outer circumference of the inner mounting shell 10 to form an end of the power connection portion 142 extending toward the PCB board 13. The PCB board 13 has a socket for inserting and positioning the extended end of the power connection portion 142. When welding the power connection spring piece 14 to the PCB board 13, the extended end of the power connection portion 142 can be inserted into the socket for positioning before welding. Therefore, when connecting the power connection spring piece 14 to the PCB board 13, the operating difficulty of installing and connecting the power connection spring piece 14 is reduced and the stability of the installation connection is improved.
[0038] Preferably, the inner mounting shell 10 comprises a first half shell 11 and a second half shell 12 which are engaged with each other. Figure 2 , Figure 4 As shown, a receiving cavity for receiving and fixing the PCB board 13 is provided in the first half shell 11 and the second half shell 12. Specifically, when the inner mounting shell 10 is configured as the first half shell 11 and the second half shell 12 that are mutually engaged, the convenience of disassembly and assembly of the built-in PCB board 13 can be increased, thereby facilitating maintenance of the PCB board 13 inside.
[0039] Preferably, a plug rod is provided on one side of the first half shell 11 facing the second half shell 12. Figure 4 As shown, a slot matching the insertion rod is provided on one side of the second half shell 12 facing the first half shell 11, and a positioning hole matching the insertion rod is penetrated by the PCB board 13 (not shown in the figure). In this embodiment, the first half shell 11 and the second half shell 12 can be snap-fitted and positioned in the form of the insertion rod and the slot, and a positioning hole matching the insertion rod can be preset on the PCB board 13, so that when the first half shell 11 and the second half shell 12 are covered to form the inner installation shell 10, the PCB board 13 can also be positioned at the same time to prevent the PCB board 13 from being deflected during installation, thereby increasing the convenience of installing and fixing the PCB board 13.

Figure 3 , Figure 4 As shown, the electrical connection spring 14 is embedded in the electrical connection piece installation groove 111. Specifically, the electrical connection spring 14 is embedded in the installation so that the portion of the electrical connection spring 14 other than the electrical connection contact 144 will not protrude from the outer periphery of the inner installation shell 10, so that interference will not occur during installation, resulting in the inability to install the pen tip 20 and the pen barrel 30.
[0041] In the present embodiment, the connection plate installation groove 111 is provided on the outer periphery of the first half shell 11, so the connection spring 14 is installed on the outer periphery of the first half shell 11. Of course, in other embodiments, the connection plate installation groove 111 can also be provided on the outer periphery of the second half shell 12, so that the connection spring 14 is installed on the outer periphery of the second half shell 12. In addition, the connection plate installation groove 111 can also be provided on the outer peripheries of the first half shell 11 and the second half shell 12 at the same time. In this way, when the connection spring 14 is installed, a part of the connection spring 14 is installed on the outer periphery of the first half shell 11, and the other part of the connection spring 14 is installed on the outer periphery of the second half shell 12. The specific opening position of the connection plate installation groove 111 is not limited here.

Figure 3 , Figure 4 , Figure 5 As shown, the outer periphery of the inner mounting shell 10 is provided with a second accommodating groove 113 for accommodating the first elastic abutting portion 145 and a first accommodating groove 112 for accommodating the second elastic abutting portion 146. Specifically, when the power-connecting spring piece 14 is installed into the pen tube 30 along with the inner mounting shell 10, when the power-connecting contact 144 of the power-connecting spring piece 14 abuts and conducts with the conductive portion of the pen tube 30, the contact portion 143 provided with the power-connecting contact 144 undergoes elastic deformation toward the inner mounting shell 10, at which time the first elastic abutting portion 145 abuts with the bottom wall of the second accommodating groove 113, and the second elastic abutting portion 146 abuts with the bottom wall of the first accommodating groove 112, limiting the elastic deformation of the contact portion 143, so that the contact portion 143 will not undergo excessive elastic deformation, thereby improving the contact firmness between the power-connecting contact 144 and the conductive portion of the pen tube 30.
[0043] Preferably, the second elastic abutting portion 146 and one end facing the installation opening form a guide notch (not shown in the figure). Specifically, the setting of the guide notch can make the end of the contact portion 143 facing the installation opening of the pen tube 30 be located on the inner side of the outer periphery of the inner installation shell 10, so that when the inner installation shell 10 is installed into the pen tube 30, it is easier to install the power-connecting spring piece 14.
[0044] Furthermore, a plurality of protrusions 15 are provided on the outer periphery of the inner mounting shell 10. Figure 2 , Figure 3 As shown, a plurality of bayonet holes 24 are formed on the outer periphery of the plug-in portion 21 and are matched with the bayonet protrusions 15 in a one-to-one bayonet manner.
[0045] In this embodiment, the latching protrusion 15 can be disposed on the outer periphery of the first half shell 11, or on the outer periphery of the second half shell 12, or on the outer peripheries of both the first half shell 11 and the second half shell 12, which is not limited here.
[0046] Specifically, when the inner mounting shell 10 is inserted into the inner opening of the inserting portion 21 , the latching protrusion 15 is latched into the corresponding latching opening 24 of the inserting portion 21 , so that the inner mounting shell 10 is latched and fixed to the pen tip 20 .
[0047] Furthermore, a plurality of positioning blocks 16 are provided on the outer periphery of the inner mounting shell 10. Figure 2 , Figure 3 As shown, the plug-in portion 21 is provided with a plurality of positioning grooves 23 along its end portion toward the exposed portion 22 for one-to-one plugging and positioning with the positioning block 16 .
[0048] In this embodiment, the positioning block 16 is arranged adjacent to the latch 15. The positioning block 16 can be arranged on the outer periphery of the first half shell 11, the outer periphery of the second half shell 12, or the outer periphery of both the first half shell 11 and the second half shell 12, which is not limited here.
[0049] Specifically, when the inner mounting shell 10 is inserted into the inner opening of the plug-in portion 21 and the inner mounting shell 10 is installed and fixed by the snap-fitting engagement between the latch 15 and the snap-fit 24, the positioning groove 23 can provide a certain elastic deformation for the wall shell of the plug-in portion 21 during the process of the latch 15 snapping into the snap-fit 24, thereby facilitating the snap-fitting of the latch 15 into the snap-fit 24 and providing installation positioning for the snap-fitting engagement between the latch 15 and the snap-fit 24.

Since the electronic stylus pen adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0051] The technical solution of the utility model adopts a method of forming a plurality of contact parts 143 on the power-connecting spring piece 14, and respectively setting a power-connecting contact 144 on each contact part 143. When the inner mounting shell 10 is first installed and fixed through the pen tip 20, and then the inner mounting shell 10 is installed to the pen tube 30 along with the pen tip 20, the power-connecting spring piece 14 is installed and fixed by inserting the inner mounting shell 10 fixed on the pen tip 20. After the pen tip 20 and the pen tube 30 are installed and fixed, the power-connecting spring piece 14 is less likely to shift than the pen tube 30.
