Description

Technical Field

[0001] This utility model relates to the field of laptop keyboards, specifically an FPC resistor structure and a resistor structure applied to MiniLED backlighting of laptop keyboards. Background Technology

[0002] To ensure users can clearly identify keys in different lighting conditions and to enhance the product's aesthetics and technological feel, more and more laptop keyboards on the market today are adopting backlit designs. The backlighting function of these keyboards is usually achieved by setting MiniLED lights on the back of the keyboard. The connection and control of the LED lights require resistors of a certain resistance value to ensure a stable current supply.

[0003] Current laptop keyboard LED designs typically employ SMT (Surface Mount Technology) processes, controlling conductor resistance by adding resistor components between conductors. However, this method has significant drawbacks: existing resistor designs are not flexible enough to meet diverse current production needs. Once the resistor components are soldered together, changing the resistance value to accommodate different current requirements necessitates redesigning and manufacturing the resistor components and re-soldering the components, undoubtedly increasing production time and costs.

[0004] Therefore, it is necessary to develop an FPC resistor structure and a resistor structure for use in MiniLED backlighting of laptop keyboards, which can more easily change the resistance value. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an FPC resistor structure that facilitates the change of resistance value and a resistor structure for use in MiniLED backlighting of notebook keyboards.

[0007] An FPC resistor structure includes a resistor main line, the resistor main line having a first main line portion and a second main line portion, a dividing line being provided between the first main line portion and the second main line portion, and the dividing line being cut to form a first gap, the first gap being for inserting a resistor.

[0008] As described above, the FPC resistor structure has an adjustment area in the first main wire portion and / or the second main wire portion, which is used for laser cutting.

[0009] As described above, in the FPC resistor structure, the first main line portion and the second main line portion are both provided with connecting edges at the ends away from the dividing line. The resistor main line is also provided with a first edge line connecting the two connecting edges, and a boundary line intersecting the two connecting edges. The adjustment area is enclosed by the first edge line, the connecting edge, and the boundary line.

[0010] As described above, in the FPC resistor structure, the adjustment area is provided with a third side line and a fourth side line that intersect with the first side line, and a second side line that connects the third side line and the fourth side line. The second side line, the third side line, and the fourth side line form a cutting area.

[0011] In the FPC resistor structure described above, the maximum area of ​​the adjustment region occupies three-quarters of the main resistor line.

[0012] In the FPC resistor structure described above, the length of the third side line is between one-tenth and three-quarters of the length of the connecting side.

[0013] In the FPC resistor structure described above, the maximum length of the second side line is three-quarters of the length of the first side line.

[0014] As described above, in the FPC resistor structure, the main resistor line, the adjustment area, and the cutting area are all rectangular in cross-section.

[0015] In the FPC resistor structure described above, the dividing line is arranged parallel to the connecting edge.

[0016] The second technical solution adopted by this utility model to solve its technical problem is:

[0017] A resistor structure for MiniLED backlighting of a laptop keyboard includes the FPC resistor structure as described above, wherein the main resistor line is further provided with connection terminals at both ends, and the connection terminals are connected to the circuitry of an external circuit board.

[0018] The beneficial effects of this utility model are:

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figures 1 to 3 An FPC resistor structure includes a resistor main line 1, wherein the resistor main line 1 has a first main line portion 15 and a second main line portion 16, a dividing line 14 is provided between the first main line portion 15 and the second main line portion 16, and the dividing line 14 is cut to form a first gap 17, the first gap 17 being used for inserting a resistor.

[0027] A resistor is connected between the first main line section 15 and the second main line section 16 to increase the resistance value. This setting makes resistance adjustment more convenient and efficient, and can respond more quickly to changes in different current requirements without redesigning and manufacturing the entire resistor component, thus reducing production costs.

[0028] Specifically, a dividing line 14 is provided between the first main line portion 15 and the second main line portion 16, and the dividing line 14 is laser-cut to form the first gap 17.

[0029] Specifically, resistor main line 1 is an element with a predetermined resistance value inside, such as a fixed resistor.

[0030] In this embodiment, after the main resistor 1 is cut along the dividing line 14, the first main wire portion 15 and the second main wire portion 16 form a mating interface at the cut position. The dividing line 14 is parallel to the connecting edge 12. This arrangement makes the mating interfaces of the first main wire portion 15 and the second main wire portion 16 after the division parallel to each other, which facilitates the connection operation of the resistor. It ensures that the mating interfaces of the first main wire portion 15 and the second main wire portion 16 are stably connected by the resistor, thereby reducing the connection instability caused by the non-parallelism of the mating interfaces, ensuring stable current conduction, and improving the reliability of the circuit.

[0031] In one embodiment, the first main wire portion 15 and / or the second main wire portion 16 are provided with an adjustment area 2, which is used for laser cutting. By laser cutting the adjustment area 2, the resistance value can be reduced.

[0032] It is understood that the main resistor 1 in this embodiment is a component with a predetermined resistance value. By setting the adjustment area 2 and the dividing line 14 on the main resistor 1, the resistance value of the main resistor 1 can be better adjusted to meet the specific requirements of different application scenarios. When it is necessary to reduce the resistance value, the adjustment area 2 can be laser-cut to reduce the resistance value. When it is necessary to increase the resistance value, the resistor can be inserted into the first gap 17 to increase the resistance value. With this setting, whether increasing or decreasing the resistance value, it is not necessary to redesign the entire circuit or remanufacture the resistor component, which greatly improves work efficiency. Furthermore, by laser-cutting the adjustment area 2 to reduce the resistance value, this setting reduces the cumbersome soldering process in traditional circuit design. It not only simplifies the operation steps, but also reduces the problems of poor contact or circuit damage that may be caused by repeated soldering, thereby improving the overall reliability and stability of the circuit and reducing production costs.

[0033] In one embodiment, the first main line portion 15 and the second main line portion 16 are each provided with a connecting edge 12 at the end away from the dividing line 14. The resistor main line 1 is also provided with a first side line 11 connecting the two connecting edges 12 and a boundary line 13 intersecting the two connecting edges 12. The adjustment area 2 is enclosed by the first side line 11, the connecting edge 12 and the boundary line 13.

[0034] In this embodiment, both the first side line 11 and the connecting side 12 are projections. In this embodiment, the adjustment area 2 is formed by the first side line 11, the connecting side 12 and the boundary line 13, and the laser is restricted to cutting only within the adjustment area 2. This setting can effectively prevent the laser from exceeding the predetermined range during the cutting process, that is, prevent the laser from cutting beyond the boundary line 13, thereby avoiding damage to the strength of the main resistor line 1 and affecting its service life, and effectively ensuring the integrity and stability of the main resistor line 1 structure.

[0035] More specifically, the dividing line 14 is arranged parallel to the connecting edge 12.

[0036] In one embodiment, the adjustment area 2 is provided with a third side line 22 and a fourth side line 24 that intersect with the first side line 11, and a second side line 21 that connects the third side line 22 and the fourth side line 24. The second side line 21, the third side line 22 and the fourth side line 24 form a cutting area 23.

[0037] In this embodiment, the second side line 21, the third side line 22, and the fourth side line 24 are all projections. In this embodiment, by setting a cutting area 23 in the adjustment area 2 and forming one or more cutting areas 23 by laser cutting according to the actual current requirements, the resistance value can be adjusted more accurately, thereby improving the flexibility of adjusting the resistance value and the circuit design, and meeting the diverse requirements for resistance values ​​in different application scenarios.

[0038] In one embodiment, the maximum area of ​​the adjustment region 2 occupies three-quarters of the main resistor line 1.

[0039] In this embodiment, the maximum area of ​​the adjustment area 2 is only three-quarters of the main resistor line 1, that is, the maximum distance from the boundary line 13 to the first side line 11 is three-quarters of the connecting side 12. This setting provides sufficient protection for the main resistor line 1, ensuring that the main conductive path of the current is not damaged after laser cutting, reducing potential risks in the cutting process, and improving the safety and reliability of the circuit.

[0040] In one embodiment, the length of the third side line 22 is between one-tenth and three-quarters of the length of the connecting side 12.

[0041] This setup ensures that the resistance can be effectively adjusted after cutting the main resistor line 1. Since there is a certain distance between the internal resistance portion of the main resistor line 1 and the first side line 11 (in this embodiment, this distance is one-tenth), the shortest length of the third side line 22 in the cutting area 23 should occupy one-tenth of the length of the connecting side 12 in order to change the resistance value of the main resistor line 1.

[0042] Furthermore, the longest length of the third side line 22 is three-quarters of the length of the connecting side 12. This setting ensures that laser cutting is only performed within the adjustment area 2, thereby preserving the main conductive path of the current and ensuring that the current flow path after cutting is not affected, thus ensuring the conductivity of the circuit.

[0043] In one embodiment, the maximum length of the second edge 21 is three-quarters of the length of the first edge 11.

[0044] In this embodiment, the maximum length of the second side line 21 is three-quarters of the length of the first side line 11. This setting ensures that the cutting area 23 and the connecting side 12 maintain an appropriate distance, thereby reserving sufficient fixing positions for both ends of the main resistor line 1, ensuring the stable fixing of the main resistor line 1, avoiding the problem of unstable connection due to insufficient fixing positions, and thus ensuring reliable current conduction, improving the overall current stability and conductivity of the circuit, thereby enhancing the overall reliability of the circuit.

[0045] In one embodiment, the main resistor line 1, the adjustment area 2, and the cutting area 23 are all rectangular in cross-section.

[0046] This embodiment achieves a uniform cross-sectional area by setting the main resistor 1, adjustment area 2, and cutting area 23 into rectangular sections. This design reduces the resistance when current flows through the main resistor 1, thereby improving conductivity, effectively reducing the heat generated by the main resistor 1, and thus improving the overall circuit performance and stability. Furthermore, by laser-cutting the rectangular section of the cutting area 23, this design allows for more convenient and accurate calculation and prediction of the resistance change after cutting, making the resistance adjustment more precise and controllable, and providing fine resistance adjustment capability for different current requirements.

[0047] In one embodiment, the dividing line 14 is arranged parallel to the connecting edge 12.

[0048] A resistor structure for MiniLED backlighting of a laptop keyboard includes an FPC resistor structure as described in any of the above embodiments, wherein the main resistor line 1 is further provided with connection terminals at both ends, and the connection terminals are connected to the circuitry of an external circuit board.

[0049] In this embodiment, the resistor main line 1 is provided with connection ends at both ends, and the connection ends can be any form of contact point or interface. This setting provides the resistor main line 1 with diversified connection methods, which not only reduces the number of components, but also enables the resistor main line 1 to adapt to various installation environments, and makes the installation and maintenance process of the resistor main line 1 simpler, ensuring that the resistor main line 1 can be quickly connected to various external circuit boards, thereby improving installation and maintenance efficiency.

[0050] Furthermore, the width of the connection end can be greater than the length of the connection side 12. A larger connection end can provide a more stable electrical connection, reduce signal attenuation and noise interference, and effectively improve signal integrity and overall circuit reliability. Furthermore, the connection end can achieve a stable connection with an external circuit board, ensuring that the resistance value of the main resistor line 1 can be effectively transmitted to the external circuit, thereby achieving effective regulation and control of the external current. Through this setting, the main resistor line 1 can be better applied to the MiniLED backlight circuit of a laptop keyboard, effectively regulating the current intensity and improving the brightness and uniformity of the MiniLED backlight. Furthermore, by adjusting the length of the main resistor line 1, the resistance value can be adjusted. The main resistor line 1 can be designed in a wavy shape. This setting can increase the length of the main resistor line 1 within a limited space, thereby increasing the resistance value.

[0051] like Figure 1-4 As shown, the implementation method of this embodiment is as follows:

[0052] Select resistor main line 1 according to requirements. In this embodiment, the length of the connecting side 12 of resistor main line 1 is preferably 5mm.

[0053] After the main resistor line 1 is connected to the circuit board, if it is necessary to reduce the resistance value, it is only necessary to cut the adjustment area 2 on the main resistor line 1 with the same area according to the calculated value. After cutting, the third edge line 22 on the cutting area 23 can be as long as 3.75mm to ensure that the conductive path of the main resistor line 1 is not destroyed, and as short as 0.5mm to ensure that the resistance inside the main resistor line 1 can be effectively cut.

[0054] If an increase in resistance is required, the first main line portion 15 and the second main line portion 16 on the main resistor line 1 can be cut along the dividing line 14. A resistor with the same or slightly larger resistance value as the required value can be added between the first main line portion 15 and the second main line portion 16 via contact points or interfaces. If the overall resistance value is too high after adding the resistor, the resistance value can be adjusted by laser cutting in the adjustment area 2 on the first main line portion 15 and the second main line portion 16 until a suitable resistance value is achieved.

[0055] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
