Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and more specifically, relates to a connector assembly, a circuit board assembly, and an electronic atomization device. Background Technology

[0002] With the continuous improvement of living standards, electronic atomization devices, especially portable electronic atomization devices, have rapidly entered thousands of households due to their convenience and practicality, gaining widespread popularity in the market and their usage scale continues to expand.

[0003] Currently, in the internal circuitry of portable e-cigarette devices, the electrical connection between two circuit boards relies on traditional pin header (bent pin) connectors. This connection method has revealed a series of problems in practical operation and application. Firstly, the installation of pin header connectors requires manual soldering. Because the pin spacing is generally small, typically 1mm or 1.27mm, the solder joints are densely packed during manual soldering, making it easy for operators to accidentally cause solder bridging. Solder bridging not only causes short circuits, rendering the e-cigarette device malfunction, but can also lead to equipment failure due to short circuits, and even pose certain safety hazards, seriously affecting product quality and user experience.

[0004] On the other hand, the pin header itself has a relatively delicate structure, making it prone to deformation and misalignment under external forces during assembly and use. Once the pin header deforms or misaligns, it not only leads to unstable electrical connections between circuit boards, affecting the performance of the electronic atomization device, but also interferes with the assembly between the circuit board and other structures within the device. During assembly, deformed or misaligned pin headers make it difficult to accurately align and install the circuit board, increasing assembly difficulty, reducing production efficiency, and also affecting the overall stability and compactness of the device's structure.

Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] As described in the background section, the electrical connection between two circuit boards in the internal circuitry of portable electronic atomizing devices relies on traditional pin header (bent pin) connectors. This connection method has revealed a series of problems in actual operation and application. Firstly, the installation of pin header connectors requires manual soldering. Because the pin spacing is generally small, typically 1mm or 1.27mm, the solder joints are densely packed during manual soldering, making it easy for operators to cause solder bridging if they are not careful. Solder bridging not only causes short circuits, preventing the electronic atomizing device from functioning properly, but can also lead to device malfunctions due to short circuits, and even poses certain safety hazards, seriously affecting product quality and user experience.

[0032] On the other hand, the pin header itself has a relatively delicate structure, making it prone to deformation and misalignment under external forces during assembly and use. Once the pin header deforms or misaligns, it not only leads to unstable electrical connections between circuit boards, affecting the performance of the electronic atomization device, but also interferes with the assembly between the circuit board and other structures within the device. During assembly, deformed or misaligned pin headers make it difficult to accurately align and install the circuit board, increasing assembly difficulty, reducing production efficiency, and also affecting the overall stability and compactness of the device's structure.

[0033] See Figures 1 to 5As shown, to solve the above problems, according to one aspect of this application, a connector assembly is provided for use in electronic atomization devices, particularly portable electronic atomization devices. The electronic atomization device includes a main body, a first circuit board 10 installed within the main body, and a second circuit board 20 positioned at a preset angle α to the first circuit board 10. The first circuit board 10 and the second circuit board 20 are the core circuit carriers within the electronic atomization device, integrating various electronic components such as chips, resistors, capacitors, and inductors to realize various functions of the electronic atomization device, such as controlling atomization power, monitoring battery power, and adjusting atomization temperature. The preset angle α between the first circuit board 10 and the second circuit board 20 can be adjusted according to the internal spatial layout and functional requirements of the electronic atomization device. For example, the preset angle α can be 90 degrees (vertical setting), aiming to rationally arrange the circuit structure within the limited device space and improve space utilization. The connector assembly includes a first electrical connection portion 31 and a second electrical connection portion 32. The first electrical connection portion 31 is mounted on the surface of the first circuit board 10, and the second electrical connection portion 32 is mounted on the end of the second circuit board 20. One of the first electrical connection portion 31 and the second electrical connection portion 32 includes a gold finger slot portion 311, and the other includes a gold finger plug portion 321. The second electrical connection portion 32 is detachably connected to the first electrical connection portion 31 through the insertion and engagement of the gold finger slot portion 311 and the gold finger plug portion 321. These are the parts of the connector assembly that are respectively connected to the first circuit board 10 and the second circuit board 20. The first electrical connection portion 31 securely mounts the gold finger slot portion 311 or the gold finger plug portion 321 onto the surface of the first circuit board 10, ensuring a reliable electrical connection between it and the circuitry on the first circuit board 10, for example, through soldering, crimping, or other methods. Similarly, the second electrical connection part 32 installs the corresponding gold finger slot part 311 or gold finger plug part 321 at the end of the second circuit board 20, so that the second circuit board 20 and the connector assembly form a reliable electrical connection.

[0034] Unlike traditional pin header (bent pin) connectors that require manual soldering and are prone to solder bridging leading to short circuits, the connector assembly of this application uses a mating connection between the gold finger slot portion 311 and the gold finger plug portion 321. This eliminates the need for manual soldering of densely packed solder joints, fundamentally avoiding the possibility of solder bridging due to human error. This significantly reduces the risk of short circuits, improves the product quality and stability of electronic atomization devices, reduces equipment damage and safety hazards caused by short circuits, and enhances the user experience.

[0035] In this application embodiment, the gold finger slot portion 311 and the gold finger plug portion 321 can achieve a tight and precise mating. Compared with the traditional pin header structure, which is thin and easily deformed and displaced by external forces, affecting the stability of the electrical connection, the connector assembly of this application can better resist external interference during assembly and use, maintain the stability of the electrical connection, ensure that the electronic atomization device can operate stably in various usage environments, and reduce device performance fluctuations or failures caused by unstable connections.

[0036] Traditional pin header connectors are prone to pin deformation and misalignment during assembly, making precise alignment of the circuit board difficult and increasing assembly difficulty and time costs. However, the connector assembly of this application features a clearly defined positioning structure and insertion direction for its gold finger slot 311 and gold finger plug 321. During assembly, operators can quickly and accurately insert the second circuit board 20 into the first electrical connection 31 on the first circuit board 10 via the second electrical connection 32, improving assembly efficiency on the production line, reducing labor costs, and ultimately enhancing the production efficiency of electronic atomization equipment to meet the growing market demand.

[0037] Especially for portable atomizing devices (such as electronic aerosol generators), which are frequently moved and susceptible to impact during daily use, the connector assembly of this application achieves a tight fit between the gold finger slot portion 311 and the gold finger plug portion 321. This makes the connection between the first circuit board 10 and the second circuit board 20 more compact, effectively reducing the shaking caused by loose components inside the device and lowering the risk of damage to the circuit board connection due to impact. This greatly enhances the durability of the device in portable use scenarios, ensuring that the device can still work stably during frequent carrying and movement, thus meeting users' needs for the reliability of portable devices.

[0038] Compared to traditional pin header connectors, whose delicate structure is easily deformed upon impact, the connector assembly of this application is designed with full consideration of the usage environment of portable devices. The material and structural design of the gold finger slot 311 and the gold finger plug 321 give it better impact resistance, further improving the overall durability of the device and providing users with a longer and more reliable user experience.

[0039] In the event of a malfunction during the use of portable atomizing devices, the detachable design of the connector assembly in this application offers significant advantages. When the device is damaged and requires repair, maintenance personnel can easily pull the second circuit board 20, which has the second electrical connection part 32 installed, from the first electrical connection part 31 on the first circuit board 10, quickly locating the faulty circuit board. Whether the first circuit board 10 or the second circuit board 20 malfunctions, it can be repaired or replaced individually without requiring large-scale disassembly of the complex circuit connections of the entire device, greatly shortening repair time and reducing repair costs.

[0040] For example, if the atomization function of the electronic aerosol generator malfunctions and the problem is determined to be with the second circuit board 20, maintenance personnel can directly detach it from the first circuit board 10 and perform separate testing and repair on the second circuit board 20. This convenient maintenance method helps improve the efficiency of after-sales maintenance, reduces downtime for user equipment, and enhances user satisfaction with after-sales service.

[0041] See Figure 2 and Figure 3 As shown, the second electrical connection portion 32 in this embodiment includes a gold finger plug portion 321, which includes a connector 3211 and a conductive contact group 3212 disposed on the connector 3211. The gold finger slot portion 311 includes a first body 3111 and a resilient contact group 3112. A slot 3113 is disposed inside the first body 3111, and the resilient contact group 3112 is installed in the slot 3113. The position of the resilient contact group 3112 corresponds to the position of the conductive contact group 3212. The connector 3211 serves as the carrier of the gold finger plug portion 321, providing stable support for the conductive contact group 3212, ensuring its positional stability during device operation and insertion / removal, and ensuring the reliability of signal transmission. The conductive contact group 3212 is regularly arranged on the connector 3211, which can accurately allocate signal lines according to the circuit function requirements, reduce signal interference and crosstalk, and enable each functional module of the device to accurately receive and process signals.

[0042] See Figure 2 and Figure 3 As shown, the internal slot 3113 of the first body 3111 of the gold finger slot portion 311 in this embodiment provides precise guidance for the insertion of the gold finger plug portion 321, facilitating installation and improving assembly efficiency. The elastic contact group 3112 is installed in the slot 3113 and corresponds strictly to the position of the conductive contact group 3212. During insertion, the elastic contacts tightly fit the conductive contacts using their own elasticity, which can provide a stable electrical connection, reduce signal interruption and current instability caused by poor contact, and buffer vibration and impact forces during equipment use, prevent contact damage or loosening, and extend the service life of the connector and equipment.

[0043] The elastic contact group 3112 in this embodiment includes a plurality of contact springs 31121, which are spaced apart along the width direction of the slot 3113; the conductive contact group 3212 includes a plurality of contact pieces 32121, which are spaced apart along the width direction of the connector 3211, and the plurality of contact pieces 32121 correspond one-to-one with the plurality of contact springs 31121. The slot 3113, as a key structure of the gold finger slot portion 311, is formed inside the first body 3111. The slot 3113 opening is considered rectangular, and its width direction refers to the direction perpendicular to the long side of the connector 3211 insertion direction, and is consistent with the arrangement direction of the metal springs (contact springs 31121) inside the slot 3113. In this direction, multiple contact springs 31121 are spaced apart. When the connector 3211 is inserted, the conductive contact pieces 32121 of the connector 3211 make contact with these contact springs 31121 one-to-one in the width direction, achieving electrical connection. The connector 3211, as the supporting component of the gold finger plug 321, also has its width direction perpendicular to the direction of its insertion into the slot 3113. Similar to the slot 3113, the connector 3211 can be considered a rectangular sheet structure. When the connector 3211 is inserted into the slot 3113, the long side perpendicular to the insertion direction is the width direction. In the width direction of the connector 3211, multiple contact pieces 32121 are arranged at regular intervals to form conductive contact groups 3212.

[0044] See Figure 2 and Figure 3 As shown, multiple contact springs 31121 are spaced apart along the width of the slot 3113, increasing the contact range with the conductive contact group 3212. When the connector 3211 is inserted into the slot 3113, each contact spring 31121 fits tightly with its corresponding contact piece 32121, forming a multi-point electrical connection. Even if some contacts experience temporary poor contact due to vibration, external force, or other factors, other contacts can still maintain circuit continuity, ensuring stable signal and current transmission and preventing power outages or signal interruptions during device operation. This provides a solid guarantee for the stable operation of electronic atomization devices, such as ensuring stable atomizer operation and preventing fluctuations in atomization power. The spaced distribution of multiple contact springs 31121 can disperse impact forces when the device is subjected to vibration, collision, or other external impacts. If individual contact springs 31121 are temporarily displaced or deformed due to external force, other contact springs 31121 can still maintain electrical connection, reducing the risk of electrical connection failure due to external force and extending the service life of connector assembly and electronic atomization device. It is especially suitable for portable electronic atomization devices that are frequently subjected to vibration and collision during daily use.

[0045] In this embodiment, there are two elastic contact groups 3112 and two conductive contact groups 3212. The two elastic contact groups 3112 are respectively disposed at opposite ends of the slot 3113, and the two conductive contact groups 3212 correspond to the two elastic contact groups 3112. In the connector assembly of the electronic atomizing device, having two elastic and two conductive contact groups 3212, respectively placed at both ends of the thickness direction of the slot 3113 (this direction is perpendicular to the insertion direction and width direction of the connector 3211), can reduce impedance from multiple aspects. Both groups of contacts conduct electricity simultaneously, widening the current path and increasing the conductive cross-sectional area. Based on the principle that resistance is inversely proportional to cross-sectional area, this reduces impedance, reduces power loss, and improves the energy utilization rate of the device. The distribution of contacts at both ends shortens the current conduction path; a shorter path results in lower impedance, which is beneficial for fast and stable signal transmission and reduces attenuation distortion. The distribution at both ends allows for more uniform and tight contact between the conductive and elastic contacts, increasing the contact area and reducing contact resistance. Even if one group of contacts is affected by external forces such as vibration, the other group can still maintain good contact, ensuring stable connection. Low impedance also optimizes electromagnetic compatibility, reduces electromagnetic radiation caused by current conduction and interference to other internal circuits, and improves the overall performance and stability of the equipment.

[0046] In today's world where electronic atomization devices are increasingly pursuing miniaturization and integration, the rational utilization of internal space is particularly crucial. In this embodiment, the first main body 3111 is mounted on the surface of the first circuit board 10, with a preset angle α of 90°. In some portable electronic atomization devices, internal space is extremely limited. Using a 90° mounting angle allows the circuit board to be stacked vertically with other components (such as batteries and atomizers), thus enabling miniaturized design, making the device lighter and more portable, and improving the user experience. Mounting the first main body 3111 on the surface of the first circuit board 10 at a preset angle α of 90° simplifies the assembly process. During assembly, workers can operate more intuitively, accurately installing and connecting various components, improving production efficiency. The 90° mounting angle also enhances the mechanical stability of the connector assembly. The vertical structure formed between the first main body 3111 and the first circuit board 10 allows them to support each other under stress, improving the vibration and impact resistance of the entire connection area.

[0047] See Figures 2 to 5As shown, according to another aspect of this application, a circuit board assembly is provided for an electronic atomizing device. The electronic atomizing device includes a housing, and the circuit board assembly includes a first circuit board 10 and a second circuit board 20 mounted within the housing. It also includes a connector assembly, which is the aforementioned connector assembly, thus possessing all the advantages of the aforementioned connector assembly. Furthermore, the connector 3211 is integrally formed with the second circuit board 20. As part of the circuit board material, the connector 3211 is integrated with the second circuit board 20, fundamentally eliminating the potential for loosening and poor connection issues that may occur with traditional spliced ​​connectors 3211. During daily use of the electronic atomizing device, neither frequent carrying causing shaking nor slight vibrations during use will affect the connection stability between the connector 3211 and the second circuit board 20. This ensures that the conductive contact group 3212 of the gold finger plug portion 321 and the elastic contact group 3112 of the gold finger slot portion 311 always maintain a tight and stable contact, ensuring continuous and stable transmission of electrical signals and current. Taking the core atomization function of electronic atomizing devices as an example, a stable connection can ensure precise control of atomization power, avoid fluctuations in atomization volume caused by unstable connection, and provide users with a consistently good user experience.

[0048] The gold finger slot portion 311 of this application embodiment includes a first body 3111 and a resilient contact group 3112. A slot 3113 is provided inside the first body 3111, and the resilient contact group 3112 is installed within the slot 3113. Opening grooves 3213 are provided between the two sides of the gold finger plug portion 321 and the second circuit board 20. The openings of the opening grooves 3213 face the first body 3111, allowing space for the sidewalls of the first body 3111. The gold finger slot portion 311 is mainly composed of the first body 3111 and the resilient contact group 3112. The first body 3111 is the supporting frame for the entire slot 3113 portion and can be made of engineering plastics with certain strength and insulation properties, such as polycarbonate (PC) or polyphenylene sulfide (PPS). These materials ensure that the slot 3113 portion is both stable and durable in complex electronic environments and effectively isolates interference between circuits. Inside the first body 3111, a slot 3113 is carved out. The shape and size of the slot 3113 are precisely matched to the shape of the gold finger plug 321. It is generally rectangular, and its length, width, and depth are determined according to the actual electrical connection requirements and the specifications of the gold finger plug 321. The purpose is to provide precise guidance for the insertion of the gold finger plug 321 and ensure that the two can be perfectly connected. The elastic contact group 3112 is the core component for realizing the electrical connection of the slot 3113 and is installed inside the slot 3113. The elastic contact group 3112 consists of multiple elastic metal springs. The springs are made of highly conductive and elastic metal materials, such as beryllium bronze alloy, and the surface is often gold-plated to further improve conductivity and corrosion resistance. They are fixed in the slot 3113 according to a specific interval and arrangement. When the gold finger plug 321 is inserted, these elastic springs can make close contact with the conductive contact group 3212 on the gold finger plug 321 to achieve stable and reliable electrical signal and current transmission.

[0049] The gold finger connector 321 is mounted on the second circuit board 20, and openings 3213 are provided between its two sides and the second circuit board 20. These two openings 3213 are located on the left and right sides of the gold finger connector 321 near the second circuit board 20 (assuming the gold finger connector 321 is mounted horizontally in a long strip shape), and form a certain spatial area with the edge of the second circuit board 20. The shape of the openings 3213 is flexible; it can be rectangular, which is convenient for manufacturing and can fit well with the sidewall of the first body 3111. Of course, under some special design requirements, it can also be trapezoidal, U-shaped, or other shapes. The key is that the opening of the opening 3213 must face the first body 3111.

[0050] The width of the opening slot 3213 needs to be adjusted according to the thickness of the side wall of the first body 3111 to ensure that the side wall of the first body 3111 can smoothly enter the opening slot 3213, while not being too loose, so as not to affect the stability of the connection between the plug and the slot 3113. The depth needs to be determined based on the space allowance between the gold finger plug 321 and the second circuit board 20 and the actual assembly operation requirements. It is necessary to ensure that there is enough room for the side wall of the first body 3111, while not excessively weakening the structural strength between the gold finger plug 321 and the second circuit board 20.

[0051] In this embodiment, the second circuit board 20 has two positioning protrusions 3214 at one end near the first body 3111, a connector 3211 is located between the two positioning protrusions 3214, and an opening slot 3213 is located between the positioning protrusions 3214 and the connector 3211. The first body 3111 has two positioning grooves 3114, the positions of which correspond to the positions of the two positioning protrusions 3214. As a key component of the electronic atomization device circuit system, the second circuit board 20 has two positioning protrusions 3214 at one end near the first body 3111. The positioning protrusions 3214 are generally columnar or block-shaped, and their material is the same as the substrate of the second circuit board 20, which can be a copper-clad epoxy glass cloth laminate. They protrude vertically upwards from the surface of the second circuit board 20. The two positioning protrusions 3214 are distributed in parallel.

[0052] The connector 3211 is located between two positioning protrusions 3214. The connector 3211 is integrally formed with the second circuit board 20 and made of the same circuit board material. Conductive contact groups 3212 are regularly arranged on the surface of the connector 3211 for electrical connection with the elastic contact groups 3112 within the slot 3113 of the first body 3111. The length and width of the connector 3211 are designed to fit snugly into the slot 3113, ensuring a tight fit during insertion.

[0053] The first body 3111 serves as the carrier of the gold finger slot 311, and two positioning grooves 3114 are provided at the part where it mates with the second circuit board 20. The positioning grooves 3114 correspond to the positioning protrusions 3214 and are matched in position. The positioning grooves 3114 are recessed inward on the surface of the first body 3111, and their shapes are complementary to the outer contour of the positioning protrusions 3214. If the positioning protrusions 3214 are cylindrical, the positioning grooves 3114 are circular recesses; if the positioning protrusions 3214 are cuboid blocks, the positioning grooves 3114 are rectangular grooves. The depth of the grooves is generally slightly greater than the height of the positioning protrusions 3214 to ensure that the positioning protrusions 3214 can fit tightly after insertion, thus playing a stable positioning role.

[0054] When connecting the second circuit board 20 to the first body 3111, the positioning protrusion 3214 of the second circuit board 20 can be aligned with the positioning groove 3114 of the first body 3111 and inserted in a specific direction. During insertion, the side wall of the first body 3111 is embedded in the opening groove 3213, providing space for the connector 3211 to smoothly enter the slot 3113 inside the first body 3111. The tight fit between the positioning protrusion 3214 and the positioning groove 3114 ensures precise alignment between the connector 3211 and the slot 3113, guaranteeing the accuracy and stability of the electrical connection, while also enhancing the mechanical stability of the entire connection structure and effectively resisting the influence of external forces such as vibration and impact during equipment use.

[0055] In this embodiment, a resilient engaging portion 31141 is provided on the side of the positioning groove 3114 near the slot 3113, and a engaging protrusion 32141 is provided on the side of the positioning protrusion 3214 near the connector 3211. The engaging protrusion 32141 engages with the resilient engaging portion 31141. The resilient engaging portion 31141 is provided on the side of the positioning groove 3114 near the slot 3113 and is made of a material with good elasticity and wear resistance, such as elastic plastic (e.g., polyoxymethylene POM) or metal elastic sheet (e.g., beryllium bronze). The structure of the resilient engaging portion 31141 can be a cantilever beam structure.

[0056] Taking the cantilever beam type elastic locking part 31141 as an example, one end of it is fixed to the side wall of the positioning groove 3114, and the other end is a free end, which can generate elastic deformation when subjected to external force. The free end is provided with a protrusion or a groove for locking with the locking protrusion 32141 on the positioning protrusion 3214.

[0057] A snap-fit ​​protrusion 32141 is located on the side of the positioning protrusion 3214 near the connector 3211. It engages with the protrusion or groove of the elastic snap-fit ​​portion 31141 to achieve the snap-fit ​​function. The snap-fit ​​protrusion 32141 can be a small protrusion. When the gold finger plug portion 321 is inserted into the gold finger slot portion 311, the positioning protrusion 3214 gradually inserts into the positioning groove 3114 as the connector 3211 moves. During insertion, the snap-fit ​​protrusion 32141 on the positioning protrusion 3214 contacts the elastic snap-fit ​​portion 31141 within the positioning groove 3114. Due to the elasticity of the elastic snap-fit ​​portion 31141, the snap-fit ​​protrusion 32141 compresses the free end of the elastic snap-fit ​​portion 31141, causing it to undergo elastic deformation. When the engaging protrusion 32141 moves to the protrusion or groove position of the elastic engaging portion 31141, the elastic engaging portion 31141 will return to its original shape, tightly locking the engaging protrusion 32141, thereby achieving the engagement between the positioning protrusion 3214 and the positioning groove 3114. This prevents loosening or detachment during use. Furthermore, when disassembly is required, simply apply a certain external force to deform the elastic engaging portion 31141 again, thus releasing the engagement and facilitating maintenance or component replacement.

[0058] According to another aspect of this application, an electronic atomizing device is provided. The electronic atomizing device includes a housing, an atomizing component installed within the housing, and a circuit board assembly. The atomizing component is electrically connected to the circuit board assembly, which is the aforementioned circuit board assembly. The circuit board assembly includes a first circuit board 10 and a second circuit board 20. The first circuit board 10 is equipped with a main control chip and LED beads. It can analyze data fed back from various sensors and accurately control the device's operating status, such as adjusting the atomization power based on battery power and optimizing the atomization time and frequency according to user operating habits, while coordinating communication between various components. The LED beads are high-brightness, low-power light-emitting diodes (LEDs), which are the intuitive visual medium for interaction between the device and the user. They convey the device's status through different on / off modes and color changes, such as a blue light when powered on, a red breathing flashing light when charging, and a solid green light when fully charged.

[0059] The second circuit board 20 integrates a charging component and a switching component. The charging component includes a charging interface (such as a Type-C interface), a charging management chip, and related circuitry. The charging interface connects to an external power source, and the charging management chip precisely controls the charging current and voltage, providing high-current fast charging when the battery is low and reducing the current to prevent overcharging when near full charge, effectively extending battery life. The switching component uses a touch-sensitive button or toggle switch for convenient user operation. It is connected to the main control chip, and signals generated by user operations are transmitted to the main control chip, causing the device to perform corresponding actions.

[0060] When the user turns on the device using the switch, the main control chip receives the signal and sends a start command to the atomizing component, providing it with appropriate voltage and current via the circuit board. The heating wire inside the atomizing component heats up, atomizing the e-liquid into an aerosol for the user. During this process, the charging component continuously supplies power, the LEDs provide real-time status feedback, and all components work together to ensure stable and efficient operation of the device.

[0061] In summary, implementing the connector assembly, circuit board assembly, and electronic atomization device provided in this embodiment has at least the following beneficial technical effects:

[0062] Portable atomizing devices (such as electronic aerosol generators) are frequently moved and susceptible to impacts during daily use. The connector assembly of this application, through the tight mating of the gold finger slot and the gold finger plug, makes the connection between the first and second circuit boards more compact. This effectively reduces internal shaking caused by loose components, lowers the risk of damage to the circuit board connection points due to impacts, and greatly enhances the durability of the device in portable use scenarios. It ensures stable operation even during frequent carrying and movement, meeting users' reliability requirements for portable devices.

[0063] Compared to traditional pin header connectors, whose delicate structure is easily deformed upon impact, the connector assembly of this application is designed with the usage environment of portable devices in mind. The material and structural design of the gold finger slot and gold finger plug give it better impact resistance, further improving the overall durability of the device and providing users with a longer and more reliable user experience. The gold-plated contacts and contacts have extremely low contact resistance, ensuring minimal loss of current and signal during transmission, thus achieving efficient and stable electrical connections. They have high wear resistance, maintaining good contact performance even after repeated mating and unmating operations, preventing poor contact or wear that could cause signal interruption. They are not easily oxidized or corroded, thus maintaining good conductivity over a long period in harsh environments.

[0064] In the event of a malfunction during the use of portable atomizing devices, the detachable design of the connector assembly in this application offers significant advantages. When the device is damaged and requires repair, maintenance personnel can easily pull the second circuit board, which has a second electrical connection, from the first electrical connection on the first circuit board, quickly locating the faulty circuit board. Whether the first or second circuit board is faulty, it can be repaired or replaced individually without requiring large-scale disassembly of the complex circuit connections of the entire device, greatly shortening repair time and reducing repair costs. The flexible plug-and-play design ensures high assembly efficiency and enables automated assembly.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
