Description

Technical Field

[0001] The utility model relates to an improved refill and pen head of a dual-system active capacitive pen, and relates to the field of active capacitive pen equipment. Background Art

[0002] Capacitive pen is a pen made of conductive material with conductive properties, used to touch the capacitive screen to complete human-computer interaction. Capacitive pen is an auxiliary device that imitates the human body to complete human-computer interaction through conductive material. With the development of APP, the current capacitive pen is no longer a simple replacement for finger operation. More and more professionals have tried to use active capacitive pens to work on mobile devices.

[0003] The pen tip of the existing dual-system active capacitive stylus is not reasonably constructed, so when the user needs to replace the pen tip after the pen tip is worn, two situations occur: one is that the secondary signal part must be disassembled to replace the pen tip, but the secondary signal part is very small and can be easily lost after being disassembled, and improper operation during disassembly will cause signal instability, affecting the use; the other is that the worn pen tip must be discarded together with the secondary signal part, resulting in unnecessary waste of resources, and the pen tip is integrated with the secondary signal part, making the cost of replacing the pen tip very high. For example, the patent technology with announcement number CN218782604U discloses a dual The utility model discloses a wireless active capacitive pen and a refill module of the system. The utility model can conveniently realize the function of switching systems through the pen tip inner core, the threaded seat, the first wire, the conductor tube, the refill seat, the spring, the conductor head, the second wire and the system switching button, thereby solving the problem that the capacitive pen usually only has one system and cannot make corresponding switches for tablets of different brands, resulting in a greatly reduced use effect, thereby improving the practicality of the capacitive pen. However, the technical solution has the above-mentioned problem that the pen tip inner core and the outer shell are an integrated structure. When the pen tip is worn and disassembled, the outer shell, the pen tip inner core and the conductor head need to be disassembled and replaced together, resulting in excessively high maintenance costs.

[0004] In order to solve the problems existing in the prior art, an improved refill and pen head of a dual-system active capacitive pen is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an improved refill pen tip for a system active capacitive stylus in view of the defects or shortcomings in the prior art. By providing a separate pen tip, primary and secondary signal terminals, when the pen tip is worn, only the pen tip part needs to be unscrewed and replaced, without the need to disassemble the internal signal parts, thereby ensuring the stability of the signal. The overall structure is simple and easy to assemble, which is conducive to reducing production and use costs.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a pen tip 1, a primary signal nail 2, a metal tube 3, and a secondary signal head 4.

The secondary signal head 4 is sleeved on the outside of the metal tube 3. The secondary signal head 4 is provided with an external thread, and the pen tip 1 is provided with an internal thread. The pen tip 1 is threadedly connected to the secondary signal head 4.

[0007] Furthermore, an insulating ring 5 is provided in the middle of the secondary signal head 4 , and the insulating ring 5 abuts against the bottom of the pen head 1 .

[0008] Furthermore, a fixing seat 6 is disposed at the tail of the secondary signal head 4 and is electrically connected to the fixing seat 6 . The fixing seat 6 abuts against the insulating ring 5 , and the fixing seat 6 exceeds the secondary signal head 4 .

[0009] Furthermore, an insulating tube 7 is sleeved on the tail of the metal tube 3 , the insulating tube 7 is flush with the outer edge of the fixing seat, and the insulating tube 7 is sleeved with the fixing seat 6 .

[0010] Furthermore, a pen core tail seat 8 is sleeved on the end of the metal tube 3. The pen core tail seat 8 is a hollow structure with a through hole opened on one side.

[0011] Furthermore, a spring 10 is provided at the end of the pen core tailstock 8 .

[0012] Furthermore, the primary signal pin 2 is electrically connected with a wire 11 , which passes through the metal tube 3 and comes out from the through hole on the side of the pen core tail seat 8 .

[0013] Furthermore, a groove is provided at the rear end of the fixing seat 6, and a ring lead 9 is provided in the groove.

[0019] Explanation of the reference numerals: pen tip 1, primary signal pin 2, metal tube 3, secondary signal head 4, insulating ring 5, fixing seat 6, insulating tube 7, pen core tail seat 8, ring lead 9, spring 10, wire 11. DETAILED DESCRIPTION

[0020] See also Figure 1-3 As shown, the technical solution adopted in this specific implementation is: it includes a pen tip 1, a primary signal nail 2, a metal tube 3, and a secondary signal head 4. The primary signal nail 2 is insulated and arranged in the front end opening of the metal tube 3 and abuts against the inner wall of the front end of the pen tip 1, and the metal tube surface is provided with an insulating layer. The secondary signal head 4 is sleeved on the outside of the metal tube 3, and the secondary signal head 4 is provided with an external thread. The pen tip 1 is provided with an internal thread. The pen tip 1 is threadedly connected with the secondary signal head 4. In the traditional structure, since the pen tip is integrated with the secondary signal parts, when the pen tip is worn and needs to be replaced, the pen tip and the secondary signal parts need to be disassembled and replaced at the same time, or some non-integrated structures require the secondary signal parts to be disassembled before the pen tip can be replaced, which not only causes the disassembly and assembly to be difficult, but also causes the burrs to be difficult to disassemble and install. The pen tip is made of hollow insulating material, which can wrap the primary signal pin and the secondary signal head. At the same time, the secondary signal head has a large body volume, which is used not only as a signal end but also as a main body. It is not easy to lose during assembly or replacement and maintenance. The primary signal pin is tightly against the pen tip, and the signal reception is better during use. The primary signal pin is arranged in the metal tube, and no other connection method is required. After being installed in the front end of the metal tube, it is constrained by the pen tip when assembled with the pen tip. It is also easy to disassemble and assemble, which also reduces the production cost.

[0021] To be more specific, an insulating ring 5 is provided in the middle of the secondary signal head 4, and the insulating ring 5 is abutted against the bottom of the pen tip 1. A fixing seat 6 is provided at the tail of the secondary signal head 4 and is electrically connected to the fixing seat 6. The fixing seat 6 is abutted against the insulating ring 5, and the fixing seat 6 exceeds the secondary signal head 4. In this embodiment, the insulating ring plays a limiting role to prevent the pen tip from being damaged due to excessive rotation of the connection. The fixing seat tightens the secondary signal head and fixes the insulating ring, and a groove is provided at the tail end of the fixing seat 6, and a ring lead 9 is provided in the groove. The lead pin of the ring lead is electrically connected to the secondary signal end of the circuit board.

[0022] To be more specific, the tail of the metal tube 3 is sleeved with an insulating tube 7, which is flush with the outer edge of the fixing seat, and is sleeved with the fixing seat 6. The insulating tube is a sliding structure sleeved on the tail of the metal tube, and is sleeved in the fixing seat at the same time. It is constrained by the fixing seat to isolate the front and rear ends, and ensure that the metal tube does not contact the fixing seat, thereby preventing short circuit and increasing tightness.

[0023] To be more specific, a core tail seat 8 is sleeved on the end of the metal tube 3. The core tail seat 8 is a hollow structure with a through hole on one side. A spring 10 is provided at the end of the core tail seat 8. A wire 11 is electrically connected to the primary signal pin 2. The wire 11 passes through the metal tube 3 and comes out from the through hole on the side of the core tail seat 8, and is electrically connected to the primary signal end of the circuit board. At the same time, a spring is provided on the core tail seat to provide a retraction feeling during use.

[0024] The working principle of the utility model is as follows: during assembly, the primary signal nail 2 is sleeved in the metal tube 3, and the wire 11 is inserted into the metal tube 3, and then the secondary signal head 4 is sleeved with the metal tube 3, the pen head 1 and the secondary signal head 4 are screwed together from the front end, and then the insulating ring 5, the fixing seat 6 and the insulating tube 7 are sequentially inserted, and finally the wire 11 is inserted into the pen core tail seat 8, and the pen core tail seat 8 is connected to the metal tube 3, and the assembly of the entire pen head part is completed. If the pen head 1 is worn during use, it is only necessary to unscrew the pen head 1 to separate it from the secondary signal head 4, so as to replace it, and there is no need to disassemble the secondary signal head 4.

[0025] 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.
