Abstract
Description
Technical Field
[0001] This disclosure relates to the field of connector technology, and more particularly to a connector and an electronic device. Background Technology
[0002] Pogo pin connectors are widely used in consumer electronics and automotive electronics for electrical signal connections between different modules. Currently, the standard pogo pin connector in the industry uses a spring and a spring embedded within a metal sleeve. The spring provides the positive force for contact, and the surrounding metal sleeve acts as a medium for current flow. Because there is a gap between the spring and the sleeve, they are susceptible to external vibrations and other environmental factors during sliding, leading to poor contact. Therefore, this structure is prone to momentary disconnections due to vibration in certain environments. Utility Model Content

[0050] See Figure 1 As shown, the currently common pogo pin connectors in the industry use a spring 92 and a spring 91 built into a metal sleeve 90. The spring 92 provides the positive force for contact. The bottom of the sleeve 90 is sealed, and the surrounding metal sleeve 90 is used as a medium to achieve current flow. The current flow path is as follows: Figure 1 As indicated by the middle arrow, due to the gap between the projectile 91 and the sleeve 90, they are susceptible to external vibrations and other environmental factors during sliding, leading to poor contact. Furthermore, the small contact area between the projectile 91 and the sleeve 90, which does not perfectly fit, limits the flow capacity. In addition, a spring 92 needs to be assembled inside the sleeve 90 to provide elasticity, making the entire device complex to assemble and increasing the cost of individual unit manufacturing.
[0051] In view of the above-mentioned problems in related technologies, this disclosure provides a connector and an electronic device. The connector and electronic device of this disclosure will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.
[0052] Example 1
[0053] See Figures 2 to 4 As shown, an embodiment of this disclosure provides a connector, which may be a pogo pin spring connector, including a sleeve 10 and a conductive spring 20.
[0054] The sleeve 10 has a hollow portion 11 inside, which extends through both ends of the sleeve 10 along its axial direction (longitudinal direction in the figure). The conductive warhead 20 includes a first warhead conductor 21 and a deformable elastic conductor 22. The elastic conductor 22 is telescopingly disposed within the hollow portion 11 along the axial direction of the sleeve 10. One end of the first warhead conductor 21 is connected to the elastic conductor 22 from inside the hollow portion 11, and the other end of the first warhead conductor 21 extends out of the hollow portion 11 for connecting to a first external module, for example, for contacting and engaging with the first external module. Since the hollow portion 11 extends through both ends of the sleeve 10, the other end of the elastic conductor 22, away from the first warhead conductor 21, is located inside the hollow portion 11 and can be used to connect to a circuit board, realizing an electrical connection between the first warhead conductor 21 and the circuit board, thereby realizing an electrical connection between the first external module connected to the first warhead conductor 21 and the circuit board. The elastic conductor 22, while acting as a current-carrying conductor, also provides elasticity to the first warp conductor 21, ensuring stable contact between the first warp conductor 21 and the first external module. Optionally, the conductive warp 20 can be made of conductive metals such as copper or stainless steel, or it can also be made of conductive materials such as graphite. The sleeve 10 can be made of insulating material. Alternatively, the sleeve 10 can also be made of conductive material, and its inner wall can have an insulating layer or not.
[0055] See Figure 5 As shown, the connector in this embodiment can be applied to electronic devices, including circuit boards 30, which have pads 31. In this application scenario, the end of the connector's elastic conductor 22 furthest from the first spring conductor 21 is soldered to the pads 31, thereby connecting the first spring conductor 21 to the circuit board 30 via the elastic conductor 22. Through the contact and engagement of the first spring conductor 21 with the first external module, in the working state, when the first spring conductor 21 is subjected to downward pressure from the first external module, it can slide within the hollow portion 11 of the sleeve 10 under the elastic action of the elastic conductor 22. The elastic force provided by the elastic conductor 22 ensures the reliability of the contact between the spring and the contact surface of the first external module, and the sleeve can guide the first spring conductor. The first spring conductor and the elastic conductor can act as current-carrying mediators, allowing current to be directly transferred from the first external module to the circuit board to achieve current flow (the current flow path is as follows). Figure 2 (As indicated by the middle arrow) By eliminating the need for a separate sleeve as a current-carrying medium, the transient interruption problem caused by poor contact between the projectile and the sleeve, as seen in conventional solutions, is avoided, resulting in more reliable electrical contact. Furthermore, by directly connecting the elastic conductor to the circuit board, the current-carrying capacity is only affected by its own resistance, eliminating the influence of contact resistance between the projectile and the metal sleeve in conventional solutions, thus enabling a larger current-carrying capacity. In addition, the elastic conductor's elasticity provides a positive contact force for the first projectile conductor, eliminating the need for an additional spring structure. This results in a compact and simple product structure, easier assembly, and reduced costs.
[0056] In some alternative embodiments, the elastic conductor 22 is a helical conductor. Along the axial direction of the sleeve 10, the end of the helical conductor is connected to the end of the first warp conductor 21. Optionally, the elastic conductor 22 can be made into a helical shape by a stamping process. The helical conductor can be a blade-type helix or a ribbon-type helix, which is beneficial for compression deformation. While acting as a current-carrying conductor, it can also provide elasticity to the first warp conductor 21, ensuring stable contact between the first warp conductor 21 and the first external module.
[0057] In some optional embodiments, the elastic conductor 22 and the first warp conductor 21 can be connected to each other by welding. Alternatively, the elastic conductor 22 and the first warp conductor 21 can be integrally formed. Optionally, the elastic conductor 22 and the first warp conductor 21 can be integrally formed by stamping, which is convenient for processing.
[0058] Combination Figure 3 As shown, in some optional embodiments, the first warhead conductor 21 includes a first body 211 and a first warhead 212. The first body 211 is connected to the elastic conductor 22, and the first warhead 212 is connected to the end of the first body 211 away from the elastic conductor 22. The first warhead 212 extends out of the hollow portion 11 for connection with the first external module, for example, for contact engagement with the first external module. Optionally, the first warhead 212 is pointed, arc-shaped, or blunt. In this embodiment, the first warhead 212 is arc-shaped to facilitate contact engagement with the first external module. Through the contact engagement between the first warhead 212 and the first external module, in the working state, when the first warhead 212 is subjected to the downward pressure of the first external module, the elasticity of the elastic conductor 22 can drive the first body 211 to slide within the hollow portion 11 of the sleeve 10. The elastic force provided by the elastic conductor 22 can ensure the contact reliability of the contact surface between the first warhead and the first external module.
[0059] Furthermore, the first body 211 and the first projectile 212 are integrally formed structures, and the elastic conductor 22, the first body 211, and the first projectile 212 are also integrally formed structures. Optionally, the first body 211 and the first projectile 212 can be integrally formed by a stamping process, and the elastic conductor 22, the first body 211, and the first projectile 212 can also be integrally formed by a stamping process, which facilitates processing.
[0060] In some optional embodiments, the first body 211 has a hollow structure, which can reduce weight. In this embodiment, the sleeve 10 is cylindrical, and the first body 211 is cylindrical to fit the sleeve 10, with the axial direction of the first body 211 coaxial with the axial direction of the sleeve 10. A first gap exists between the first body 211 and the sleeve 10 in a direction perpendicular to the axial direction of the sleeve 10 (transverse in the figure), the first gap ranging from 0.1mm to 0.5mm. Within this gap range, the guiding function of the sleeve on the first body is not affected, and the influence of friction between the sleeve and the first body on the sliding of the first body is reduced.
[0061] See Figure 5 As shown, this embodiment of the present disclosure provides an electronic device, including a circuit board 30 and the connector described in Embodiment 1 above. The circuit board 30 is provided with a pad 31, and the end of the elastic conductor 22 of the connector away from the first warp conductor 21 is connected to the pad 31, thereby realizing the electrical connection between the first warp conductor 21 and the circuit board 30.
[0062] In this application scenario, the end of the connector's elastic conductor 22 furthest from the first spring conductor 21 is soldered to the pad 31, thereby connecting the first spring conductor 21 to the circuit board 30 via the elastic conductor 22. Through the contact and engagement between the first spring conductor 21 and the first external module, in the working state, when the first spring conductor 21 is subjected to downward pressure from the first external module, it can slide within the hollow portion 11 of the sleeve 10 under the elastic force of the elastic conductor 22. The elastic force provided by the elastic conductor 22 ensures the reliability of the contact between the spring and the contact surface of the first external module, and the sleeve can guide the first spring conductor. The first spring conductor and the elastic conductor can act as current-carrying mediators, allowing current to be directly transferred from the first external module to the circuit board to achieve current flow (the current flow path is as follows). Figure 2 As shown by the middle arrow, the sleeve is no longer used as a separate current-carrying medium, thus avoiding the problem of momentary interruption due to poor contact in conventional solutions and making electrical contact more reliable.
[0063] Example 2
[0064] See Figures 6 to 8 As shown, this disclosure also provides a connector, which may be a pogo pin spring connector, including a sleeve 10 and a conductive spring 20.
[0065] The sleeve 10 has a hollow portion 11 inside, which extends through both ends of the sleeve 10 along its axial direction (longitudinal direction in the figure). The conductive warhead 20 includes a first warhead conductor 21, a second warhead conductor 23, and a deformable elastic conductor 22. The elastic conductor 22 is telescopically disposed within the hollow portion 11 along the axial direction of the sleeve 10. One end of the first warhead conductor 21 is connected to the elastic conductor 22 from inside the hollow portion 11, and the other end of the first warhead conductor 21 extends out of the hollow portion 11 for connecting to a first external module, for example, for contacting and engaging with the first external module. One end of the second warhead conductor 23 is connected to the end of the elastic conductor 22 away from the first warhead conductor 21 from inside the hollow portion 11, and the other end of the second warhead conductor 23 extends out of the hollow portion 11 for connecting to a second external module, for example, for contacting and engaging with the second external module. That is, the first warhead conductor 21 and the second warhead conductor 23 are respectively connected to the two ends of the elastic conductor 22. Since the hollow portion 11 extends through both ends of the sleeve 10, the ends of the first warp conductor 21 and the second warp conductor 23 furthest from the elastic conductor 22 can both extend out of the hollow portion 11 for contact and engagement with two different external modules, thereby achieving electrical connection between the two different external modules. The elastic conductor 22, while acting as a current-carrying conductor, also provides elasticity to the first warp conductor 21 and the second warp conductor 23, ensuring stable contact between the first warp conductor 21 and the first external module, and stable contact between the second warp conductor 23 and the second external module. Optionally, the conductive warp 20 can be made of conductive metals such as copper or stainless steel, or it can also be made of conductive materials such as graphite. The sleeve 10 can be made of insulating material. Alternatively, the sleeve 10 can also be made of conductive material, and the inner wall of the sleeve 10 can have an insulating layer, or it can be without an insulating layer.
[0066] See Figure 9 As shown, the connector in this embodiment can be applied to electronic devices. The electronic device includes a frame 32, and optionally, it may also include a circuit board 30, which has the frame 32. The application scenario involves fixing the connector sleeve 10 to the frame 32. The first spring conductor 21 contacts and engages with the first external module, and the second spring conductor 23 contacts and engages with the second external module. In operation, when the first spring conductor 21 and the second spring conductor 23 are subjected to downward pressure from the first and second external modules respectively, they can slide within the hollow portion 11 of the sleeve 10 under the elastic action of the elastic conductor 22. The elastic force provided by the elastic conductor 22 ensures stable contact between the first spring conductor and the first external module, and stable contact between the second spring conductor and the second external module. The sleeve can guide the first and second spring conductors. The first spring conductor, the second spring conductor, and the elastic conductor can act as current-carrying mediators, allowing current to be directly transferred from the first external module to the second external module (current path as follows). Figure 6As indicated by the middle arrow, the sleeve is no longer used as a separate current-carrying medium, avoiding the momentary interruption problem caused by poor contact between the projectile and the sleeve in conventional solutions, thus making the electrical contact more reliable. Furthermore, the first and second external modules are directly connected through the first and second projectile conductors and the elastic conductor. The current-carrying capacity is only affected by its own resistance, eliminating the influence of contact resistance between the projectile and the metal sleeve in conventional solutions, enabling a larger current-carrying capacity. In addition, the elastic conductor provides a positive contact force for the first and second projectile conductors, eliminating the need for an additional spring structure. The entire product structure is compact and simple, easier to assemble, and reduces costs.
[0067] In some optional embodiments, the elastic conductor 22 is a helical conductor. Along the axial direction of the sleeve 10, the two ends of the helical conductor are respectively connected to the end of the first warp conductor 21 and the end of the second warp conductor 23. Optionally, the elastic conductor 22 can be made into a helical shape by a stamping process. The helical conductor is a blade-type helix or a ribbon-type helix, which is beneficial for compression deformation. While acting as a current-carrying conductor, it can also provide elasticity to the first warp conductor 21, ensuring stable contact between the first warp conductor 21 and the first external module.
[0068] In some optional embodiments, the elastic conductor 22, the first warp conductor 21, and the second warp conductor 23 can be connected to each other by welding. Alternatively, the elastic conductor 22, the first warp conductor 21, and the second warp conductor 23 can be integrally formed. Optionally, the elastic conductor 22, the first warp conductor 21, and the second warp conductor 23 can be integrally formed by stamping, which is convenient for processing.
[0069] Combination Figure 7 As shown, in some optional embodiments, the first warhead conductor 21 includes a first body 211 and a first warhead 212. The first body 211 is connected to the elastic conductor 22, and the first warhead 212 is connected to the end of the first body 211 away from the elastic conductor 22. The first warhead 212 extends out of the hollow portion 11 for connection with a first external module, such as for contact engagement with the first external module. Optionally, the first warhead 212 is pointed, arc-shaped, or blunt. In this embodiment, the first warhead 212 is arc-shaped to facilitate contact engagement with the first external module.
[0070] The second warhead conductor 23 includes a second body 231 and a second warhead 232. The second body 231 is connected to the elastic conductor 22, and the second warhead 232 is connected to the end of the second body 231 away from the elastic conductor 22. The second warhead 232 extends out of the hollow portion 11 for connection with a second external module, such as for contact and engagement with the second external module. Optionally, the second warhead 232 is pointed, arc-shaped, or blunt. In this embodiment, the second warhead 232 is arc-shaped to facilitate contact and engagement with the second external module.
[0071] The first warhead 212 contacts and engages with the first external module, and the second warhead 232 contacts and engages with the second external module. In operation, when the first warhead 212 and the second warhead 232 are subjected to downward pressure from the first and second external modules respectively, the elastic conductor 22 enables the first body 211 and the second body 231 to slide within the hollow portion 11 of the sleeve 10. The elastic force provided by the elastic conductor 22 ensures the reliability of contact between the first warhead and the first external module, as well as the reliability of contact between the second warhead and the second external module.
[0072] Furthermore, the first body 211 and the first projectile 212 are integrally formed structures, as are the elastic conductor 22, the first body 211, and the first projectile 212. Similarly, the second body 231 and the second projectile 232 are integrally formed structures, as are the elastic conductor 22, the second body 231, and the second projectile 232. All of these integrally formed structures can be achieved through a stamping process, facilitating manufacturing.
[0073] In some optional embodiments, the first body 211 and the second body 231 are hollow structures, which can reduce weight. In this embodiment, the sleeve 10 is cylindrical, the first body 211 is a cylindrical shape adapted to the sleeve 10, and the second body 231 is a cylindrical shape adapted to the sleeve 10. The axial direction of the first body 211 is coaxial with the axial direction of the sleeve 10, and the axial direction of the second body 231 is coaxial with the axial direction of the sleeve 10. A first gap exists between the first body 211 and the sleeve 10 in a direction perpendicular to the axial direction of the sleeve 10 (transverse direction in the figure), the first gap ranging from 0.1mm to 0.5mm. A second gap exists between the second body 231 and the sleeve 10, the second gap ranging from 0.1mm to 0.5mm. Within this gap range, the guiding function of the sleeve on the first and second bodies is not affected, and the influence of friction between the sleeve and the first and second bodies on the sliding of the first body is reduced.
[0074] See Figure 6 and Figure 7 As shown, in some optional embodiments, the inner wall of the sleeve 10 is provided with a first limiting part 12 and a second limiting part 13, and the first limiting part 12 and the second limiting part 13 are arranged along the axial direction of the sleeve 10.
[0075] The elastic conductor 22 is provided with a third limiting part 221 for limiting engagement with the first limiting part 12 and a fourth limiting part 222 for limiting engagement with the second limiting part 13. The third limiting part 221 and the fourth limiting part 222 are arranged along the axial direction of the sleeve 10. Along the axial direction of the sleeve 10, the third limiting part 221 and the fourth limiting part 222 are located between the first limiting part 12 and the second limiting part 13. Optionally, the first limiting part 12 and the second limiting part 13 can be arranged in a ring around the inner wall of the sleeve 10, or they can be arranged on the same straight line as the third limiting part 221 and the fourth limiting part 222, as long as it can be ensured that when the conductive bullet 20 slides to the limit position along the sleeve 10, the first limiting part 12 and the third limiting part 221 can abut against each other for limiting, and the second limiting part 13 and the fourth limiting part 222 can abut against each other for limiting.
[0076] With the aforementioned limiting mechanism, when the conductive projectile 20 slides upward along the sleeve 10, the limiting action of the first limiting part 12 and the third limiting part 221 prevents the metal projectile 20 from falling out of the hollow part 11 of the sleeve 10. When the conductive projectile 20 slides downward along the sleeve 10, the limiting action of the second limiting part 13 and the fourth limiting part 222 prevents the metal projectile 20 from falling out of the hollow part 11 of the sleeve 10.
[0077] See Figure 9 As shown, this disclosure also provides an electronic device, including a frame 32 and the connector described in Embodiment 2 above, wherein the sleeve 10 is fixedly assembled and connected to the frame 32. Optionally, the electronic device may further include a circuit board 30, which is provided with the frame 32.
[0078] The application scenario involves fixing and assembling the connector sleeve 10 to the frame 32. The first contact conductor 21 engages with the first external module, and the second contact conductor 23 engages with the second external module. In operation, when the first and second contact conductors 21 and 23 are subjected to downward pressure from the first and second external modules respectively, they can slide within the hollow portion 11 of the sleeve 10 under the elastic action of the elastic conductor 22. The elastic force provided by the elastic conductor 22 ensures the contact reliability of the first contact surface with the first external module and the second contact surface with the second external module. The sleeve guides the first and second contact conductors. The first contact conductor 21, the second contact conductor 23, and the elastic conductor 22 act as current-carrying media, allowing current to be directly transferred from the first external module to the second external module (current path as follows). Figure 6 As indicated by the middle arrow, the sleeve is no longer used as a separate current-carrying medium, thus avoiding the instantaneous interruption problem of poor contact between the projectile and the sleeve in conventional solutions, making the electrical contact more reliable.
[0079] Understandable. Figures 2 to 5 In Embodiment 1 shown, the conductive warhead is a single-warhead structure. Figures 6 to 9 In Embodiment 2 shown, the conductive warp head is a double warp head structure, which makes the connector disclosed herein adaptable to a wider range of application scenarios and has a broader applicability.
