Description

Technical Field

[0001] This application relates to the field of smart wearable technology, and in particular to an electrical connection structure and a smart wearable device. Background Technology

[0002] Smart wearable devices such as watches and earphones typically use conductive pins to connect their internal circuitry to external circuitry, enabling charging and / or data transmission between the wearable device and other electronic devices. Current smart wearable devices generally have a main circuit board placed parallel to the casing. The space enclosed by the main circuit board and the casing houses functional components such as batteries and heart rate sensors. The conductive pins pass through the bottom wall of the casing and connect electrically to the main circuit board via spring-loaded pins. The direction of the conductive pins is perpendicular to the mounting surface of the main circuit board. This means the conductive pins occupy space intended for functional components, potentially reducing the number of functional components and causing the wearable device to forgo some functions. Alternatively, the functional components (such as the battery) may be reduced in size, sacrificing battery energy density and resulting in insufficient battery life. Utility Model Content

[0030] Seal 50. Detailed Implementation

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] 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 at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] Smart wearable devices such as watches and earphones typically use conductive pins to connect their internal circuitry to external circuitry, enabling charging and / or data transmission between the wearable device and other electronic devices. In current designs, the internal circuitry of a smart wearable device usually includes a main circuit board placed parallel to the casing. This main circuit board and the casing form a storage space primarily for functional components such as batteries, heart rate sensors, gyroscopes, and microphones. These functional components are core to the specific functions of the smart wearable device; for example, the battery provides continuous power, the heart rate sensor monitors the user's health data, the gyroscope detects the device's posture and movement, and the microphone collects sound signals. However, in current designs, the conductive pin passes through the bottom wall of the casing and then connects to the main circuit board using a spring-loaded pin. Furthermore, the direction of the conductive pin's insertion is perpendicular to the mounting surface of the main circuit board. This design causes the conductive pin to occupy the storage space originally intended for functional components. Because the conductive pin requires space, manufacturers have to compromise on the layout of the functional components. Manufacturers either reduce the number of functional components, ultimately causing smart wearable devices to abandon some functions, such as the inability to simultaneously support heart rate monitoring and gyroscope functions, or the inability to achieve high-quality audio effects; or they reduce the size of functional components (such as batteries), resulting in insufficient battery life and affecting user experience. Therefore, how to improve the existing design of conductive pins penetrating the bottom wall of the housing to increase the storage space of smart wearable devices, allowing them to accommodate more or larger functional components, has become a pressing problem for those skilled in the art. To solve these problems, this application provides an electrical connection structure (such as...) Figure 1 (as shown) and smart wearable devices.

[0037] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The electrical connection structure 100 of this application includes a housing 10, a main circuit board 20, a conductive pin 30, and an electrical connector 40. The housing 10 includes a bottom wall 11 and a side wall 12. The side wall 12 extends from the periphery of the bottom wall 11 and forms a receiving cavity 13 with the bottom wall 11. The main circuit board 20 is housed within the receiving cavity 13 and includes a mounting surface 21 for mounting electrical devices. The conductive pin 30 passes through the side wall 12 of the housing 10. The conductive pin 30 includes a first end 31 and a second end 32. The first end 31 of the conductive pin 30 protrudes from the outside of the housing 10, and the second end 32 of the conductive pin 30 protrudes from the receiving cavity 13. The insertion direction of the conductive pin 30 is parallel to the mounting surface 21. Electrical connector 40 is located in the accommodating cavity 13. Electrical connector 40 is electrically connected to conductive pin 30 and main circuit board 20. Electrical connector 40 includes a third end 32 connected to conductive pin 30 and a fourth end 33 electrically connected to mounting surface 21. An angle A is provided between the orientation of the third end 32 and the orientation of conductive pin 30. The angle A is greater than 0° and less than 180°.

[0038] Specifically, the electrical connection structure 100 is an integrated component system in the smart wearable device 1000 used to realize the transmission of electrical signals between internal circuits and external circuits or devices. The core function of the electrical connection structure 100 is to ensure the efficient and stable flow of electrical energy or data signals between the internal parts of the device (such as the main circuit board 20) and external interfaces (such as chargers, data cables, or other devices) through physical connections and conductive paths. The electrical connection structure 100 is jointly composed of the housing 10, the main circuit board 20, the conductive pins 30, and the electrical connectors 40. The electrical connection structure 100 provided in this application can reduce the space occupied by the conductive pins 30 by optimizing the insertion direction of the conductive pins 30 (making the insertion direction of the conductive pins 30 parallel to the mounting surface 21 of the main circuit board 20 rather than perpendicular to it), thereby increasing the number and volume of functional devices that can be accommodated inside the smart wearable device 1000.

[0039] More specifically, the housing 10 is the outer protective structure of the smart wearable device 1000. The housing 10 consists of a bottom wall 11 and side walls 12, and serves to provide mechanical support, physical protection, and encapsulation of internal components. The bottom wall 11 is the basic planar portion of the housing 10, typically serving as a mounting base for the main circuit board 20 or other devices. The side walls 12 are walls extending vertically or obliquely from the periphery of the bottom wall 11. Together with the bottom wall 11, the side walls 12 form a cavity 13 (i.e., the internal space of the smart wearable device 1000), which houses the main circuit board 20, battery, sensors, and other core components. The housing 10 also provides waterproof, dustproof, and shock-resistant properties for the smart wearable device 1000, ensuring the stable operation of the internal components.

[0040] More specifically, the main circuit board 20 is the core circuit carrier inside the smart wearable device 1000. The main circuit board 20 is responsible for integrating and electrically connecting various electronic components (such as processors, memory, sensors, etc.) to realize the functional logic control and signal processing of the smart wearable device 1000. The main circuit board 20 has a mounting surface 21 for mounting electrical components. The mounting surface 21 is the surface on the main circuit board 20 used for soldering or fixing electronic components. The mounting surface 21 is placed parallel to the bottom wall 11 of the housing 10 to maximize the use of the vertical space of the accommodating cavity 13.

[0041] More specifically, the conductive pin 30 is a metal conductive device that penetrates the side wall 12 of the housing 10, used to establish a physical connection channel between the internal circuitry of the smart wearable device 1000 and external devices, enabling charging, data transmission, or signal interaction functions. The conductive pin 30 is horizontally inserted along the side wall 12 of the housing 10 (i.e., the insertion direction is parallel to the mounting surface 21 of the main circuit board 20). Compared with the traditional insertion direction perpendicular to the mounting surface 21 of the main circuit board 20, the insertion direction of the conductive pin 30 in this embodiment can reduce the vertical space occupied by the conductive pin 30 in the accommodating cavity 13.

[0042] Furthermore, the conductive pin 30 includes a first end 31 and a second end 32. The first end 31 is the interface end of the conductive pin 30 exposed to the outside of the housing 10, and is used to connect to external devices such as chargers and data cables. The second end 32 is the contact end of the conductive pin 30 extending into the accommodating cavity 13, and is electrically connected to the main circuit board 20 through the electrical connector 40. To ensure long-term stable electrical performance, in this application, the conductive pin 30 can be made of materials with high conductivity and corrosion resistance (such as copper alloys, copper-aluminum alloys, etc.).

[0043] More specifically, the electrical connector 40 is an intermediate conductive device located within the accommodating cavity 13, used to achieve a flexible or rigid electrical connection between the conductive pin 30 and the main circuit board 20, ensuring reliable transmission of signals or electrical energy. The electrical connector 40 can be an alloy spring or a wire, etc. The electrical connector 40 itself is bendable, thereby further compressing its own space and further reducing the space volume occupied by the electrical connection structure 100. The electrical connector 40 includes a third end 32 connected to the conductive pin 30 and a fourth end 33 electrically connected to the mounting surface 21. The orientation of the third end 32 and the orientation of the conductive pin 30 are provided at an angle A (e.g., ...). Figure 3 As shown, the X-axis indicates the orientation of the third end 32, and the Y-axis indicates the orientation of the conductive pin 30, with an included angle A greater than 0° and less than 180°. Because the included angle between the third end 32 and the conductive pin 30 can be set very flexibly, the electrical connection between the conductive pin 30 and the electrical connector 40 is very stable and not easily broken during user operation.

[0044] It is understood that this application provides an electrical connection structure 100, which includes a housing 10, a main circuit board 20, a conductive pin 30, and an electrical connector 40. The housing 10 includes a bottom wall 11 and a side wall 12. The side wall 12 extends from the periphery of the bottom wall 11 and, together with the bottom wall 11, forms a receiving cavity 13 that can accommodate internal components of an electronic device (such as the main circuit board 20). The main circuit board 20 includes a mounting surface 21 for mounting electrical components. The conductive pin 30 passes through the side wall 12 of the housing 10, thereby providing more space for other functional components. The conductive pin 30 includes a first end 31 and a second end 32. The first end 31 of the conductive pin 30 protrudes from the outside of the housing 10, and the second end 32 of the conductive pin 30 protrudes from the receiving cavity 13. The direction of penetration of the conductive pin 30 is parallel to the mounting surface 21. The electrical connector 40 is also located within the receiving cavity 13 and electrically connects the conductive pin 30 and the main circuit board 20. In this application, since the conductive needle 30 passes through the side wall 12 of the housing 10 and is connected to the main circuit board 20 through the electrical connector 40, the smart wearable device 1000 has a larger storage space. Therefore, the smart wearable device 1000 can be configured with larger functional devices (such as batteries), thereby improving the battery life of the smart wearable device 1000.

[0045] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the electrical connector 40 includes a conductive spring 41, which includes a first connecting portion 411, a second connecting portion 412, and a third connecting portion 413. The first connecting portion 411 abuts against the mounting surface 21 of the main circuit board 20 and is electrically connected to the main circuit board 20. The second connecting portion 412 is mechanically connected to the second end 32 of the conductive pin 30 and is electrically connected to the conductive pin 30. The opposite ends of the third connecting portion 413 are respectively connected to the first connecting portion 411 and the second connecting portion 412.

[0046] Specifically, the conductive spring 41 is a metal conductive device with elastic deformation capability. The conductive spring 41 is used to establish a flexible electrical connection path inside the smart wearable device 1000. The conductive spring 41 compensates for assembly tolerances or vibration effects through its own structural deformation, ensuring the stability of electrical conduction between the main circuit board 20 and the conductive pin 30. The conductive spring 41 adapts to the relative positional deviation between the main circuit board 20 and the conductive pin 30 through deformation, avoiding poor contact caused by rigid connections. The conductive spring 41 also achieves circuit interconnection in different directions (such as vertical and horizontal) through multiple connecting parts, thereby optimizing the internal spatial layout of the smart wearable device 1000.

[0047] Furthermore, the conductive spring 41 includes a first connecting portion 411, a second connecting portion 412, and a third connecting portion 413. The first connecting portion 411 abuts against the mounting surface 21 of the main circuit board 20 and is electrically connected to the main circuit board 20. The first connecting portion 411 is the end structure that directly contacts the conductive spring 41 and achieves electrical connection with the main circuit board 20, and is usually the bottom or planar extension of the spring. The first connecting portion 411 can be attached to the mounting surface 21 of the main circuit board 20 by planar contact or welding to ensure low resistance conduction, thereby transmitting the electrical energy or data signal of the main circuit board 20 to the conductive pin 30 through the spring, or transmitting the electrical energy or data signal of the conductive pin 30 to the main circuit board 20 through the spring. The second connecting portion 412 is the end structure that is mechanically fixed and electrically connected to the second end 32 (the inner end of the accommodating cavity 13) of the conductive spring 41. The second connecting portion 412 can be a lateral extension or clamping structure of the spring. The second connecting part 412 is physically connected to the second end 32 of the conductive pin 30 by clamping, welding, or snapping to prevent detachment. The second connecting part 412 serves as a conductive path between the conductive pin 30 and the spring sheet, transmitting externally input electrical energy or signals to the main circuit board 20. The third connecting part 413 is an intermediate transition structure in the conductive spring sheet 41 connecting the first connecting part 411 and the second connecting part 412. The third connecting part 413 can be a bent or folded portion of the spring sheet, responsible for transmitting deformation and maintaining overall mechanical strength. The third connecting part 413 absorbs positional deviations between the main circuit board 20 and the conductive pin 30 through its elastic bending or folding design, which can be used to avoid rigid stress concentration. The third connecting part 413 serves as a conductive path between the first connecting part 411 and the second connecting part 412, ensuring continuous transmission of electrical signals or current.

[0048] Please see Figure 2 and Figure 3 In some embodiments, the first connecting portion 411 is in surface contact or line contact with the mounting surface 21.

[0049] It is understandable that the contact method between the first connecting part 411 and the mounting surface 21 can be surface contact or line contact.

[0050] Please see Figure 2 , Figure 3 and Figure 5In some embodiments, the second connecting portion 412 includes a first sub-portion 4121, a second sub-portion 4122, and a third sub-portion 4123. One end of the first sub-portion 4121 is connected to the third connecting portion 413; the second sub-portion 4122 is connected to the other end of the first sub-portion 4121; and the third sub-portion 4123 is connected to the other end of the first sub-portion 4121 and is spaced apart from the second sub-portion 4122 to form a clamping space 4124. The second end 32 of the conductive needle 30 passes through the clamping space 4124 and is clamped by the second sub-portion 4122 and the third sub-portion 4123.

[0051] Specifically, the first sub-part 4121 is the starting part of the second connecting part 412, connecting the third connecting part 413 and the second sub-part 4122, and the third sub-part 4123 (in Figure 5 (The middle part is blocked by the third connecting part 413). The first sub-part 4121 plays the role of signal and force transmission. The first sub-part 4121 transmits the signal from the third connecting part 413 to the second sub-part 4122 and the third sub-part 4123, ensuring the overall conductivity of the conductive spring 41. The first sub-part 4121 provides a stable connection base for the second sub-part 4122 and the third sub-part 4123, enhancing the mechanical strength of the entire conductive spring 41.

[0052] Specifically, the second sub-part 4122 is part of the second connecting part 412, connected to the other end of the first sub-part 4121, and spaced apart from the third sub-part 4123 to form a clamping space 4124. Together, the second sub-part 4122 and the third sub-part 4123 clamp the second end 32 of the conductive needle 30 through the space formed by their relative spacing, thereby ensuring a stable connection of the conductive needle 30. As part of the conductive path, the second sub-part 4122 is used to transmit electrical signals or current, thus ensuring the reliability of the electrical connection.

[0053] Specifically, the third sub-part 4123 is another part of the second connecting part 412, also connected to the other end of the first sub-part 4121, and spaced apart from the second sub-part 4122 to form a clamping space 4124. The third sub-part 4123 and the second sub-part 4122 work together to form the clamping space 4124, thereby ensuring that the second end 32 of the conductive needle 30 is stably clamped. As part of the conductive path, the third sub-part 4123 can transmit electrical signals or current, ensuring the reliability of the electrical connection.

[0054] Specifically, the clamping space 4124 is a space formed by the relative spacing between the second sub-part 4122 and the third sub-part 4123, used to clamp the second end 32 of the conductive pin 30. The clamping space 4124, through the relative spacing of the space, fixes the second end 32 of the conductive pin 30, preventing the conductive pin 30 from loosening or falling off. The clamping space 4124 allows the conductive pin 30 to move within a certain range to ensure that the conductive pin 30 can adapt to assembly tolerances or vibration environments, and to ensure that a stable electrical connection can be established between the conductive pin 30 and the main circuit board 20.

[0055] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the second end 32 of the conductive needle 30 includes an installation section 321 and a limiting section 322. The installation section 321 passes through the clamping space 4124 and is clamped by the second sub-part 4122 and the third sub-part 4123. The limiting section 322 is connected to at least one end of the installation section 321. In a plane perpendicular to the insertion direction, the size of the limiting section 322 is larger than the size of the clamping space 4124 and larger than the size of the installation section 321.

[0056] Specifically, the mounting section 321 is part of the second end 32 of the conductive pin 30. The mounting section 321 is used to form a clamping connection with the second connecting portion 412 (i.e., the second sub-part 4122 and the third sub-part 4123) of the conductive spring 41 to ensure the stable installation and electrical conduction of the conductive pin 30 inside the smart wearable device 1000. The mounting section 321 passes through the clamping space 4124 of the conductive spring 41. The mounting section 321 achieves a reliable electrical connection with the main circuit board 20 through the elastic clamping force of the second sub-part 4122 and the third sub-part 4123. The shape and size design of the mounting section 321 ensures that the conductive pin 30 is not easily loosened when subjected to external force, while allowing the conductive pin 30 to be finely adjusted within a certain range to adapt to assembly tolerances.

[0057] Specifically, the limiting segment 322 is another part of the second end 32 of the conductive needle 30, located at one end of the mounting segment 321. It is used to limit the movement range of the conductive needle 30 in the vertical insertion direction, preventing it from slipping out of the clamping space 4124 due to external forces. The lateral dimension of the limiting segment 322 (in the plane perpendicular to the insertion direction) is larger than the size of the clamping space 4124 and also larger than the size of the mounting segment 321, thus forming a physical barrier to prevent the conductive needle 30 from sliding out in the vertical direction. The limiting segment 322 can be a structure with a certain degree of rigidity to withstand external forces and prevent displacement of the conductive needle 30 due to vibration or impact. During installation, the limiting segment 322 can also serve as a positioning reference to ensure the correct alignment of the conductive needle 30 with the conductive spring 41.

[0058] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the third connecting portion 413 includes a plurality of connected bent portions 4131, and in the direction of the vertical mounting surface 21, the distance between the lowest point of the third connecting portion 413 and the bottom wall 11 is greater than or equal to 0.5 mm.

[0059] Specifically, the bent portion 4131 is the part of the third connecting portion 413 that has undergone multiple bends. The bent portion 4131 is used to provide a flexible connection and adapt to space requirements. The third connecting portion 413 includes multiple interlocking bent portions 4131, each of which serves to connect and provide flexibility. The bent portion 4131 can be made of a material with good elasticity and conductivity, such as a beryllium copper alloy.

[0060] More specifically, in the direction of the vertical mounting surface 21, the distance between the lowest point of the third connecting portion 413 and the bottom wall 11 is greater than or equal to 0.5 mm. This design ensures that the bending portion 4131 provides a flexible connection without interfering with other components, guaranteeing the reliability and stability of the overall electrical connection structure 100. The bending portion 4131 plays a crucial role in the overall electrical connection structure 100. The bending portion 4131 not only needs to provide a reliable electrical connection but also needs to possess a certain degree of mechanical stability to withstand vibrations and impacts that the smart wearable device 1000 may experience during use. Through the elastic deformation capability of the bending portion 4131, it can compensate for minor positional deviations between the main circuit board 20 and the conductive pin 30, ensuring a stable electrical connection. Furthermore, the structural design of the bending portion 4131 needs to comprehensively consider both electrical and mechanical performance to ensure the reliability and durability of the entire electrical connection structure 100.

[0061] Please see Figure 2 , diagram, and Figure 4 In some embodiments, the conductive pin 30 is located at half the height of the sidewall 12 in the direction perpendicular to the mounting surface 21; and / or, the conductive pin 30 is at the same height as the circuit board in the direction perpendicular to the mounting surface 21; or, the conductive pin 30 is closer to the bottom wall 11 than the circuit board in the direction perpendicular to the mounting surface 21.

[0062] Specifically, in the direction of the vertical mounting surface 21 (i.e., the height direction of the housing 10), the conductive pin 30 is positioned at the midpoint of the vertical height of the side wall 12 (i.e., the midpoint of the total height of the side wall 12). This embodiment centrally positions the conductive pin 30 to avoid it being too close to the bottom wall 11 or the opening of the housing 10, thereby balancing the space distribution within the accommodating cavity 13 and reducing interference from the conductive pin 30 to other functional devices. In the direction of the vertical mounting surface 21, the conductive pin 30 is positioned at the same horizontal level as the mounting surface 21 of the main circuit board 20 (i.e., the circuit board surface). The horizontal insertion direction of the conductive pin 30 is parallel to the circuit board plane, allowing the second end 32 of the conductive pin 30 (one end inside the accommodating cavity 13) to directly connect to the pads or interfaces on the edge of the circuit board via an electrical connector 40 (such as a conductive spring 41), without occupying additional vertical space, thus freeing up more area for functional devices such as batteries and sensors.

[0063] Specifically, in the direction of the vertical mounting surface 21, the conductive pin 30 is positioned below the mounting surface 21 of the main circuit board 20, and closer to the bottom wall 11 of the housing 10. This design is suitable for situations where the charging or data interface needs to be located at the bottom of the device (such as watch charging contacts), conforming to user plugging and unplugging habits. Moving the conductive pin 30 downwards also provides more layout space for components above the circuit board (such as displays and processors).

[0064] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the conductive needles 30 include multiple ones, and the electrical connectors 40 include multiple ones; the sidewall 12 is provided with multiple spacers 121 on the inner side of the receiving cavity 13, the multiple spacers 121 are arranged sequentially at intervals along the direction perpendicular to the insertion direction, and an installation space 122 is formed between adjacent spacers 121, each electrical connector 40 is housed in an installation space 122, and adjacent electrical connectors 40 are separated by spacers 121.

[0065] Specifically, the spacer 121 is a protrusion or partition structure located inside the side wall 12 of the housing 10. The spacers 121 are arranged sequentially at intervals along the direction of penetration of the conductive pins 30 (i.e., the horizontal direction), thereby forming multiple independent installation spaces 122. The core function of the spacers 121 is to ensure that each electrical connector 40 is installed independently and without interference through physical isolation.

[0066] Specifically, each installation space 122 accommodates only one electrical connector 40 to avoid short circuits or signal interference caused by multiple electrical connectors 40 coming into contact.

[0067] Please see Figure 2 , Figure 3 , Figure 4 and Figure 6In some embodiments, the sidewall 12 is provided with an insertion groove 123; the bottom of the insertion groove 123 is provided with a through hole 1231 communicating with the receiving cavity 13, and the second end 32 of the conductive needle 30 passes through the through hole 1231; the conductive needle 30 also includes a limiting part 33, the limiting part 33 is located between the first end 31 and the second end 32 of the conductive needle 30, the limiting part 33 is accommodated in the insertion groove 123 and abuts against the bottom of the insertion groove 123; and / or, the electrical connection structure 100 also includes a sealing member 50, the sealing member 50 is sleeved on the conductive needle 30 and located in the insertion groove 123.

[0068] Specifically, the insertion groove 123 is a recessed structure formed on the side wall 12 of the housing 10. The insertion groove 123 is used to accommodate the limiting part 33 and / or the sealing member 50 of the conductive needle 30, and to provide positioning and fixing space for the insertion of the conductive needle 30. The recessed structure of the insertion groove 123 can guide the insertion direction of the conductive needle 30, ensuring that the conductive needle 30 is aligned with the through hole 1231 and avoiding assembly misalignment of the conductive needle 30. The insertion groove 123 can also limit the range of motion of the limiting part 33 or the sealing member 50 of the conductive needle 30 through the space inside the groove, preventing the conductive needle 30 from moving axially.

[0069] Specifically, the through hole 1231 is a through hole formed at the bottom of the insertion groove 123, connecting the insertion groove 123 and the receiving cavity 13 of the housing 10, allowing the second end 32 of the conductive needle 30 to pass through and extend into the receiving cavity 13. The through hole 1231 serves as a passage for the conductive needle 30, ensuring stable contact between the second end 32 of the conductive needle 30 and the electrical connector 40 (such as a conductive spring 41) within the receiving cavity 13. The diameter of the through hole 1231 can be slightly larger than the outer diameter of the second end 32 of the conductive needle 30, allowing the conductive needle 30 to pass through while preventing excessive shaking of the conductive needle 30 during user operation.

[0070] Specifically, the limiting part 33 is a protrusion or step structure on the conductive needle 30 located between the first end 31 (exposed end) and the second end 32 (connecting end), used to limit the axial displacement of the conductive needle 30 within the insertion groove 123. The limiting part 33 abuts against the bottom of the insertion groove 123 to prevent the conductive needle 30 from penetrating excessively into the housing 10 in the insertion direction (e.g., pushing inward).

[0071] Specifically, the seal 50 is an annular elastic element (such as an O-ring or silicone sleeve) fitted over the conductive needle 30. The seal 50 is located within the insertion groove 123 and fills the gap between the conductive needle 30 and the insertion groove 123, thereby achieving a sealed protection. The seal 50 prevents external liquids, dust, or gases from entering the housing 10 by elastically compressing and filling the gap. The seal 50 also absorbs the vibration energy of the conductive needle 30 when subjected to external impact, protecting the stability of the internal electrical connection structure 100.

[0072] In summary, this application provides an electrical connection structure 100, which includes a housing 10, a main circuit board 20, a conductive pin 30, and an electrical connector 40. The housing 10 includes a bottom wall 11 and a side wall 12. The side wall 12 extends from the periphery of the bottom wall 11 and, together with the bottom wall 11, forms a receiving cavity 13 that can accommodate internal components of an electronic device (such as the main circuit board 20). The main circuit board 20 includes a mounting surface 21 for mounting electrical components. The conductive pin 30 passes through the side wall 12 of the housing 10, thereby providing more space for other functional components. The conductive pin 30 includes a first end 31 and a second end 32. The first end 31 of the conductive pin 30 protrudes from the outside of the housing 10, and the second end 32 of the conductive pin 30 protrudes from the receiving cavity 13. The direction of penetration of the conductive pin 30 is parallel to the mounting surface 21. The electrical connector 40 is also located within the receiving cavity 13 and electrically connects the conductive pin 30 and the main circuit board 20. In this application, since the conductive needle 30 passes through the side wall 12 of the housing 10 and is connected to the main circuit board 20 through the electrical connector 40, the smart wearable device 1000 has a larger storage space. Therefore, the smart wearable device 1000 can be configured with larger functional devices (such as batteries), thereby improving the battery life of the smart wearable device 1000.

[0073] In some embodiments, this application also provides a smart wearable device 1000, which includes the electrical connection structure 100 in any of the above embodiments.

The housing 10 includes a bottom wall 11 and a side wall 12. The side wall 12 extends from the periphery of the bottom wall 11 and forms a cavity 13 with the bottom wall 11 to accommodate internal components of an electronic device (such as the main circuit board 20). The main circuit board 20 includes a mounting surface 21 for mounting electrical components. The conductive pin 30 passes through the side wall 12 of the housing 10, thereby providing more space for other functional components.

The direction of penetration of the conductive pin 30 is parallel to the mounting surface 21. Electrical connector 40 is also located within the accommodating cavity 13, and electrically connects the conductive pin 30 and the main circuit board 20. In this application, since the conductive pin 30 passes through the side wall 12 of the housing 10 and is connected to the main circuit board 20 via the electrical connector 40, the smart wearable device 1000 has a larger accommodating space. Therefore, the smart wearable device 1000 can be configured with larger functional components (such as batteries), thereby improving the battery life of the smart wearable device 1000.
