DETAILED DESCRIPTION

[0023] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: it includes a pen tube 6, a main bracket 7 and a sub-bracket 8 are arranged in the pen tube 6, a circuit board 11 is arranged between the main bracket 7 and the sub-bracket 8, and a power management module and a signal processing module are arranged on the circuit board 11. In the traditional active capacitive pen structure, two circuit boards are usually used, which leads to a longer overall capacitive pen, a larger volume, a higher production cost, and a more complicated assembly process;

[0024] A conical head 5 is provided at the front end of the pen tube 6, and a stylus pen head is provided at the front end of the conical head 5. The stylus pen head includes a plastic head 1 and a metal rod 2. The metal rod 2 is provided in the plastic head 1, and the rear end of the metal rod 2 passes through the conical head 5 and is electrically connected to the circuit board 11. Traditional active capacitive pen heads mostly adopt a threaded structure, and the pen head and the pen tube are assembled by threaded connection, which increases the difficulty of production and processing. Therefore, in this embodiment, a sleeve-type stylus pen head structure is adopted, and the metal rod is sleeved in the plastic head. The assembly of the stylus pen head is completed by connecting the metal rod and the conical head, which not only reduces the processing difficulty, but also improves the assembly speed, reduces the production cost, and can effectively reduce the overall volume.

[0025] To be more specific, an insulating seat 4 is provided inside the conical head 5, a connecting rod 3 is provided inside the insulating seat 4, the connecting rod 3 is sleeved with the metal rod 2, and the insulating seat is not only an insulating structure, but also a limiting and fixing structure of the pen tip.

[0026] To be more specific, a conductive spring is provided inside the connecting rod 3 and connected to the metal rod 2. Traditional capacitive pen tips are mostly connected by wires. If they are assembled incorrectly, poor contact may easily occur. In this embodiment, a conductive spring structure is used to connect the metal rod, which not only has a stable connection but also is easier to assemble.

[0027] To be more specific, the connecting rod 3 is connected to the circuit board 11 via a wire, and the wire is connected to the conductive spring.

[0028] More specifically, a battery 9 is disposed at the front end of the circuit board 11 , and the battery 9 is electrically connected to the circuit board 11 .

[0029] More specifically, magnets 10 are provided at the front and rear ends of the battery 9, and the magnets can be adsorbed with magnetic materials, so as to facilitate the storage and carrying of the capacitive stylus.

[0030] More specifically, a button is provided at the end of the circuit board 11, and a protective ring 13 is provided on the button cover. The button on the circuit board can control the start and stop of the capacitive pen, which can save the power of the capacitive pen and prevent misoperation.

[0031] To be more specific, a tail stock 16 is provided at the end of the pen tube 6, and the tail stock 16 is embedded in the end of the main bracket 7 through a groove. The tail stock 16 and the pen tube 6 cooperate in limiting to fix the main bracket 7. The tail stock can strengthen the fixation of the main bracket and also serves as a cover for the end of the pen tube.

[0032] More specifically, a tail cap 17 is movably provided at the end of the tail stock 16, and a fixing column of the tail cap 17 penetrates into the tail stock 16. The tail cap, as the end structure of the capacitive stylus, not only improves the overall aesthetics, but also serves as a press switch.

[0033] To be more specific, a fixing nail 14 is also provided at the end of the circuit board 11, and the nail body of the fixing nail 14 is sleeved with the fixing column of the tail cap 17. A spring 15 is provided on the fixing nail 14. One end of the spring 15 is against the fixing nail 14, and the other end is sleeved on the fixing column of the tail cap 17 and connected to the inner hole of the outer wall of the fixing column. The fixing nail is pushed against the button by the spring, and when the tail cap is pressed, the fixing nail can press the button to realize the switch.

[0034] To be more specific, a diffuser 12 is provided on one side of the circuit board 11, and a plurality of lamp holes are provided at the main bracket 7 corresponding to the diffuser 12. The signal lights provided on the circuit board 11 correspond to the lamp holes. The light emitted by the signal light on the circuit board passes through the diffuser to expand the light range, and the light is partitioned through the lamp holes on the main bracket and then transmitted to the pen tube for display.

[0035] The working principle of the utility model is as follows: the plastic head 1 is sleeved with the metal rod 2, and the end of the metal rod 2 passes through the plastic head 1 to become a contact end. The stylus pen head is assembled by sleeved with the metal rod 2 and the connecting rod 3. There is no need for a threaded connection like a traditional structure, which is not only inconvenient to connect, but also more complicated to produce and process. At the same time, only one circuit board 11 with integrated power management and signal processing chips is provided, which simplifies the circuit structure and reduces the overall volume of the capacitive pen. The end of the capacitive pen is connected to the button on the circuit board 11 through an elastically arranged tail cap 17, and the tail cap 17 can be conveniently pressed to start or turn off the capacitive pen.

[0036] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
