Description

Technical Field

[0001] The present application relates to the field of keys, and in particular to a pluggable magnetic axis key. Background Art

[0002] Magnetic axis keys are an emerging key technology that mainly realizes key functions through the interaction between magnetic materials and Hall modules. Unlike traditional mechanical keys, magnetic axis keys use the principle of magnetic induction to not only provide accurate key response, but also bring a more stable and lasting user experience. At present, most magnetic axis keys on the market integrate the Hall module (Hall chip) used for magnetic sensing on the PCB board, while the magnetic axis key body only provides a magnetic axis or magnetic block close to the Hall module to achieve induction triggering.

[0003] However, with the development of the industry, integrated magnetic axis buttons have emerged, that is, the Hall module is integrated into the button module and connected to the PCB board through pin soldering. Although this design simplifies some structures, it also leads to a significant reduction in the overall reliability of the magnetic axis buttons. For ordinary consumers, they are unable to carry out repairs and replacements. Once a single button fails, the entire system basically needs to be disassembled, and special tools (such as a welding gun or a hot air gun) are used to separate the PCB board from the Hall module, and then the button is removed to install and weld the new button. This complexity and professionalism means that in actual applications, damage to a single magnetic axis button will cause the entire device to be scrapped. Utility Model Content

[0004] The purpose of this application is to overcome at least one of the shortcomings of the prior art and provide a plug-in magnetic axis key, which uses a plug-in connection structure, and the shaft can be easily plugged in and out. Even if a single shaft is damaged, the user can quickly replace it without welding. This not only extends the service life of the device and reduces the user's maintenance cost, but also improves the user experience.

[0005] To achieve the above-mentioned purpose, the present application discloses a pluggable magnetic axis button, including a button body and a pluggable connector cooperating with the button body, wherein the button body includes a base shell, a shaft body inserted into the base shell and capable of being reset, a magnetic block arranged on the shaft body, and a Hall device installed in the base shell and aligned with the magnetic block, and when the shaft body moves, it drives the magnetic block to approach or move away from the Hall device, thereby realizing the triggering of a magnetic induction signal; the Hall device has at least two pluggable pins extending downward from the base shell; the pluggable connector includes an insulating base with sockets corresponding to the number and positions of the pluggable pins, and a contact spring arranged in the insulating base and partially positioned in the sockets, wherein the contact spring has a connecting portion extending out of the insulating base, and when working, the pluggable pins of the button body are inserted into the sockets and contact the springs to realize electrical conduction.

[0006] In some embodiments, the pluggable connector is fixedly mounted on the PCB board, and the connection part is electrically connected to the circuit on the PCB board.

[0007] In some embodiments, each connection hole in the pluggable connector is provided with a pair of elastic pieces close to each other in cooperation, and the two elastic pieces form an elastic plugging position that cooperates with the plugging pin.

[0008] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0009] 1. Improve stability and reliability: The key body includes a base shell, a resetable shaft body, a magnetic block and a Hall device. The movement of the shaft body drives the magnetic block to approach or move away from the Hall device, realizing the triggering of the magnetic induction signal. The Hall device has plugging pins, which contact the contact elastic pieces in the pluggable connector to ensure electrical conduction, improving the functional stability and reliability of the key.

[0010] 2. Simplify maintenance and replacement: The pluggable connector is fixedly mounted on the PCB board. The plugging pins of the key body can be easily inserted into the jacks of the connector, realizing quick replacement and maintenance, solving the problem that traditional integrated magnetic shaft keys are difficult to maintain, extending the service life of the device, and reducing the maintenance cost of users.

[0011] The beneficial effects listed above do not exhaust all advantages. Other potential beneficial effects and detailed technical implementation manners will be further revealed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 4 As shown, this embodiment discloses an exemplary structure of a plug-in magnetic axis key, the overall structure of which includes a key body 1 and a plug-in connector 2 matched with the key body 1. Among them, the key body 1 includes a base shell 101, a shaft body 102 inserted into the base shell 101 and repositionable, a magnetic block arranged on the shaft body 102, and a Hall device installed in the base shell 101 and aligned with the magnetic block. The Hall device has at least two plug-in pins 103 extending downward from the base shell 101. The plug-in connector 2 includes an insulating base 201 with sockets corresponding to the number and position of the plug-in pins 103, and a contact spring 202 arranged in the insulating base 201 and partially located in the socket, and the contact spring 202 has a connecting portion 203 extending out of the insulating base 201.

[0022] Specifically, the base shell 101 of the key body 1 is made of wear-resistant and compression-resistant plastic material, and specifically, ABS or polycarbonate (PC) material can be selected. This material is not only lightweight and high-strength, but also has good durability and impact resistance, and can maintain structural integrity during frequent pressing and use. A guiding groove is designed inside the base shell 101 to limit the movement path of the shaft body 102 and ensure its vertical movement during pressing.

[0023] Specifically, the shaft body 102 is made of high-strength engineering plastic or metal material, and common materials such as nylon or aluminum alloy. The design of the shaft body 102 includes a central cylinder and several auxiliary support structures to ensure that stress can be evenly dispersed when it is subjected to external force and prevent deformation. A key cap connection structure is provided at the top of the shaft body 102, which can be firmly connected to the key cap. A magnet mounting groove is provided in the middle of the shaft body 102 for fixing the magnet.

[0024] Specifically, the magnet is usually made of rare earth permanent magnet material, such as neodymium iron boron (NdFeB), which has strong and stable magnetism. The magnet is fixed at the bottom of the shaft body 102. When the shaft body 102 moves up and down in the base shell 101, the magnet approaches or moves away from the Hall device accordingly, realizing the triggering of the magnetic induction signal.

[0025] Specifically, the Hall device uses a high-sensitivity Hall sensor chip, which is usually made of silicon-based material and has the characteristics of fast response and high precision. The Hall device is installed at a specific position in the base shell 101 and is accurately aligned with the magnet. The Hall device detects the position change of the shaft body 102 through the change of the magnetic induction signal, thereby generating an electrical signal. The plug-in pins 103 of the Hall device are made of highly conductive metal material, such as copper or gold-plated copper, to ensure the stability of signal transmission and low resistance.

[0026] In this embodiment, the insulating base 201 in the plug-in connector 2 is made of engineering plastic with high temperature resistance and anti-aging properties, and specifically, PBT or LCP material can be selected. These materials can be used in a complex electrical environment for a long time and are not easily aged and deformed. Jacks adapted to the positions and numbers of the plug-in pins 103 are provided on the insulating base 201 to ensure that the plug-in pins 103 of the key body 1 can be accurately docked. Contact elastic pieces 202 are provided inside the jacks. The contact elastic pieces 202 are made of highly elastic metal material, such as phosphor bronze or stainless steel, and have good electrical conductivity and elasticity. When the key body 1 is inserted, the elastic pieces 202 are in close contact with the plug-in pins 103 to achieve stable electrical conduction.

[0027] Specifically, the design of the contact elastic piece 202 includes an arc-shaped elastic structure that can provide reliable mechanical support and electrical contact when the key body 1 is inserted, ensuring good conduction performance during repeated plugging and unplugging. The part of the elastic piece 202 extending outside the insulating base 201 is the connecting part 203, which is used for electrical conduction with the circuit on the PCB board 3.

[0028] In this embodiment, the PCB board 3 is the main circuit carrier component in the keyboard, on which various electronic components and key signal processing modules are installed and connected. In practical applications, to prevent position interference, the pluggable connector 2 is usually installed on the back of the PCB board 3, while the key body 1 is located on the front of the PCB board 3. To achieve the connection between the pluggable pin 103 and the pluggable connector 2, corresponding holes are opened on the PCB board 3 so that the pluggable pin 103 can pass through the PCB board 3 and be inserted into the jack of the pluggable connector 2.

[0029] In actual use, when the user presses the key body 1, the shaft body 102 moves downward in the base shell 101, driving the magnet close to the Hall device. The Hall device senses the change in the magnetic field and generates an electrical signal. This electrical signal is transmitted through the pluggable pin 103 of the Hall device to the contact elastic piece 202 in the pluggable connector 2 and is conducted to the circuit on the PCB board 3 through the connecting part 203, realizing signal input.

[0030] To increase the reliability and maintainability of the key, the pluggable connector 2 is fixedly installed on the back of the PCB board 3, and the connecting part 203 is electrically conducted with the circuit on the PCB board 3 to ensure the stability of signal transmission. In a specific use scenario, for example, when the mechanical structure or the Hall device of a certain key body 1 is damaged, the user can simply pull out the damaged key body 1 and insert a new key body 1. The entire replacement process does not require soldering or complex tools. Just align the pluggable pin 103 with the jack of the pluggable connector 2 and insert it to ensure contact with the contact elastic piece 202 for electrical conduction. In this way, even if a single key is damaged, the user can quickly replace it, avoiding the scrapping of the entire device and improving the service life of the device.

[0031] In specific implementation, when a certain key body 1 is damaged, the user gently pulls out the damaged key body 1 with his hand or an appropriate tool to separate the pluggable pin 103 from the pluggable connector 2. Subsequently, the user takes out a new key body 1, aligns it with the jack of the pluggable connector 2, and inserts the pluggable pin 103 into the jack to ensure contact with the contact elastic piece 202 for electrical conduction. The entire replacement process does not require professional skills and can be easily completed by ordinary consumers, significantly reducing the maintenance cost.

[0032] Although exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the scope of protection of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
