The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] Please refer to Figures 1 to 6. The present application provides a spring connector for connecting to an electronic device 3, including a shell 1 and a spring body 2. The shell 1 is provided with an opening 11 and a receiving cavity 12 that are interconnected. The shell 1 is used to connect to a circuit board 4. The spring body 2 includes a first elastic arm 21, a contact portion 22, and a second elastic arm 23. The first elastic arm 21, the contact portion 22, and the second elastic arm 23 are connected end to end in sequence. The end of the first elastic arm 21 away from the contact portion 22 extends out of the receiving cavity 12 and is connected to the shell 1. The end of the second elastic arm 23 away from the contact portion 22 extends into the receiving cavity 12 and is provided with a conducting portion 231. The contact portion 22 extends out of the opening 11.

[0030] As an example of the use of the above-mentioned spring connector, please refer to Figures 2 to 4. First, the housing 1 is fixed to the circuit board 4 and connected to the circuit board 4 by one of the following methods, including but not limited to welding, bonding, or plugging. Then, the contact portion 22 extends out of the opening 11 and contacts the external electronic device 3. The contact portion 22 is compressed and moved by the external electronic device 3, and drives the first elastic arm 21 and the second elastic arm 23 to be compressed and deformed and to move accordingly. Then, the second elastic arm 23 drives the conductive portion 231 to move to the bottom of the receiving cavity 12, and the conductive portion 231 slides along the bottom of the receiving cavity 12 and contacts the bottom of the receiving cavity 12 to form a first path. Finally, the first elastic arm 21 is connected to the housing 1 to form a second path, thereby forming a dual-path structure. Through the above-mentioned method, the area of ​​the conductive path can be increased, the stroke of the conductive path can be reduced, and the contact impedance can be reduced, thereby improving the conductive performance of the spring connector.

[0031] Regarding the aforementioned housing 1, referring to Figures 2 to 4 , in some embodiments, the housing 1 is a semi-enclosed housing 1, i.e., the housing 1 does not completely cover the spring body 2 except for the contact portion 22. The first elastic arm 21 is located outside the housing 1, and the second elastic arm 23 is located inside the housing 1. This approach can reduce the overall size and cost of the spring connector.

[0032] Regarding the aforementioned housing 1, in other embodiments, the housing 1 is a fully enclosed housing 1, that is, the housing 1 completely covers and wraps the spring body 2 except for the contact portion 22, wherein the first elastic arm 21 and the second elastic arm 23 are both located inside the housing 1. This approach can provide better protection for the spring body 2, effectively reducing damage to the spring body 2 caused by collision or compression.

[0033] Furthermore, referring to Figures 2 to 4 , the first elastic arm 21, the second elastic arm 23, and the contact portion 22 are integrally formed, and the first elastic arm 21 is integrally formed with the housing 1. Through the above-described approach, the entire spring connector can be formed into an integral structure, thereby improving the structural strength of the spring connector, reducing the risk of failure or breakage at each connection point of the spring connector, and avoiding unstable conduction caused by unstable connection at each connection point of the spring connector in a non-integrated structure, thereby improving the conductive performance of the spring connector.

[0034] Furthermore, referring to Figures 2 to 4 , the contact portion 22 is arranged at an angle relative to the opening 11. When the spring connector is connected to the external electronic device 3, the contact portion 22 makes contact with the external electronic device 3 at an angle and achieves conduction, thereby avoiding the uneven contact pressure caused by vertical contact between the contact portion 22 and the external electronic device 3. This allows for a uniform contact pressure between the contact portion 22 and the external electronic device 3, thereby strengthening the connection between the spring connector and the external electronic device 3 and ensuring stable conduction between the spring connector and the external electronic device 3.

[0035] Regarding the contact portion 22, please refer to Figures 2 to 4. In some embodiments, the contact portion 22 is arc-shaped. When the contact portion 22 is in contact with the external electronic device 3, as the external electronic device 3 applies pressure to the contact portion 22, the pressure on the contact portion 22 drives the first elastic arm 21 and the second elastic arm 23 to deform, thereby generating rolling friction between the arc-shaped surface of the contact portion 22 and the contact surface of the external electronic device 3. Over time, this can effectively remove dirt or oxides on the arc-shaped surface of the contact portion 22, helping to keep the arc-shaped surface of the contact portion 22 clean, reducing the contact impedance of the contact portion 22, and thus improving the conductivity of the contact portion 22, that is, improving the conductivity of the spring connector.

[0036] Furthermore, referring to Figures 2 to 4 , the conductive portion 231 is formed by bending the end of the second elastic arm 23, and the conductive portion 231 is arranged in an arc shape. In this manner, when the spring connector is connected to the external electronic device 3, the second elastic arm 23 is pressed to drive the curved surface of the conductive portion 231 into contact and conduction with the bottom surface of the receiving cavity 12. This can ensure uniform contact pressure between the curved surface of the conductive portion 231 and the bottom surface of the receiving cavity 12, thereby improving the conductive stability between the conductive portion 231 and the housing 1, thereby further ensuring stable conductive connection between the spring connector and the external electronic device 3.

[0037] In addition, the second elastic arm 23 is pressed to drive the curved surface of the conductive part 231 and the bottom surface of the receiving cavity 12 to produce sliding friction. Over time, this can effectively remove dirt or oxides on the curved surface of the conductive part 231, help keep the curved surface of the conductive part 231 clean, reduce the contact resistance of the conductive part 231, and thus improve the conductive performance of the conductive part 231, that is, further improve the conductive performance of the spring connector.

[0038] Further, referring to Figures 5 and 6, the housing 1 is provided with an anti-hook portion 13, which is located at the periphery of the opening 11, and the second elastic arm 23 is provided with an anti-hook protrusion 233. The anti-hook portion 13 is used to block the anti-hook protrusion 233 from extending out of the opening 11 to prevent the second elastic arm 23 from being hooked and deformed.

[0039] Regarding the anti-hooking portion 13 and anti-hooking protrusion 233, please refer to Figures 5 and 6. In some embodiments, the anti-hooking portion 13 is formed by extending and bending a plate located at the periphery of the opening 11 and is integrally formed with the periphery of the opening 11, which effectively improves the structural strength of the anti-hooking portion 13. The anti-hooking protrusion 233 is formed by extending plates located on opposite sides of the second elastic arm 23 and is integrally formed with the second elastic arm 23, which also effectively improves the structural strength of the anti-hooking protrusion 233. When the spring body 2 is hooked out of the receiving cavity 12 by an external object, the anti-hooking protrusion 233 automatically abuts against the anti-hooking portion 13, so that the anti-hooking portion 13 forms a barrier against the anti-hooking protrusion 233, effectively preventing the spring body 2 from escaping the receiving cavity 12 and causing irreversible deformation and damage.

[0040] For the structure of the above-mentioned first elastic arm 21, please refer to Figures 4 to 6. The first elastic arm 21 includes a first connecting arm 211, a second connecting arm 212 and a third connecting arm 213. The first connecting arm 211 is connected to the shell 1, one end of the second connecting arm 212 is connected to the end of the first connecting arm 211 away from the shell 1, the other end of the second connecting arm 212 is connected to the third connecting arm 213, and the third connecting arm 213 is connected to the contact portion 22. The second connecting arm 212 is perpendicular to the first connecting arm 211, and the second connecting arm 212 and the third connecting arm 213 are inclined, and the third connecting arm 213 is inclined relative to the opening 11.

[0041] For the above-mentioned first connecting arm 211, second connecting arm 212 and third connecting arm 213, please refer to Figures 4 to 6. In some embodiments, the first connecting arm 211, the second connecting arm 212 and the third connecting arm 213 are all located outside the accommodating cavity 12, and a first bend is formed at the connection between the first connecting arm 211 and the shell 1, a second bend is formed at the connection between the first connecting arm 211 and the second connecting arm 212, and a third bend is formed at the connection between the second connecting arm 212 and the third connecting arm 213. Through the above-mentioned arrangement, the risk of breakage at the connection between the shell 1, the first connecting arm 211, the second connecting arm 212 and the third connecting arm 213 can be effectively reduced, thereby improving the reliability of the first elastic arm 21 and ensuring the conduction stability of the first elastic arm 21.

[0042] Regarding the structure of the second elastic arm 23, please refer to Figures 4 to 6. The second elastic arm 23 includes a fourth connecting arm 232. One end of the fourth connecting arm 232 extends out of the opening 11 and is connected to the contact portion 22. The fourth connecting arm 232 is arranged at an angle relative to the opening 11. The conductive portion 231 is located at the other end of the fourth connecting arm 232. The conductive portion 231 is suspended in the receiving cavity 12.

[0043] Furthermore, since the second elastic arm 23 is arranged at an angle relative to the opening 11, when the second elastic arm 23 is compressed and deformed and produces corresponding tilting movement, in order to avoid the second elastic arm 23 from colliding with the shell 1 during the tilting movement, please refer to Figures 4 to 6. The shell 1 is also provided with a notch 14, which is connected to the opening 11, and the notch 14 is adjacent to the opening 11, and the notch 14 is connected to the accommodating cavity 12. The notch 14 is used for the second elastic arm 23 to pass through to prevent the second elastic arm 23 from colliding with the shell 1.

[0044] Due to the provision of the notch 14, in order to prevent the spring body 2 from being hooked out of the receiving cavity 12 by external objects and extending along the notch 14, thereby causing irreversible deformation and damage to the spring body 2, as shown in Figures 4 to 6, in some embodiments, the housing 1 is further provided with a blocking portion 18. The blocking portion 18 is located at the periphery of the notch 14 and is used to prevent the anti-hooking protrusion 233 from extending out of the notch 14. Specifically, the blocking portion 18 is formed by extending and bending a plate located at the periphery of the notch 14, and is integrally formed with the periphery of the notch 14, which can effectively improve the structural strength of the blocking portion 18.

[0045] Regarding the structure of the housing 1, please refer to FIG. 2 and other figures. The housing 1 includes a base plate 15, a first baffle 16, and a second baffle 17. The first baffle 16 and the second baffle 17 are connected to opposite sides of the base plate 15. The base plate 15, the first baffle 16, and the second baffle 17 collectively enclose a receiving cavity 12 and an opening 11. Through the above-described method, when the spring connector is connected to the external electronic device 3, the first elastic arm 21 and the second elastic arm 23 of the spring body 2 are compressed and deformed and simultaneously received in the receiving cavity 12. The housing 1 can protect the first elastic arm 21 and the second elastic arm 23, preventing external objects from colliding with the first elastic arm 21 and the second elastic arm 23, which may cause unstable conduction of the spring body 2.

[0046] Regarding the above-mentioned housing 1, please refer to Figure 2 and other figures. In some embodiments, the substrate 15, the first baffle 16 and the second baffle 17 are integrally formed, that is, the substrate 15, the first baffle 16 and the second baffle 17 are formed by a single plate through multiple bending actions.

[0047] The shrapnel connector of the present application is used to connect to an electronic device 3. The shrapnel connector includes a housing 1 and a shrapnel body 2. The housing 1 is provided with an opening 11 and a receiving cavity 12 that are interconnected. The housing 1 is used to connect to a circuit board 4. The shrapnel body 2 includes a first elastic arm 21, a contact portion 22, and a second elastic arm 23. The first elastic arm 21, the contact portion 22, and the second elastic arm 23 are connected end to end in sequence. The end of the first elastic arm 21 away from the contact portion 22 extends out of the receiving cavity 12 and is connected to the housing 1. The end of the second elastic arm 23 away from the contact portion 22 extends into the receiving cavity 12 and is provided with a conductive portion 231. The contact portion 22 extends out of the opening 11. When the contact portion 22 is connected to the electronic device 3, the contact portion 22 is compressed and drives the conductive portion 231 to contact and connect with the receiving cavity 12 to form a first path. The first elastic arm 21 is connected to the housing 1 to form a second path. The dual-path conductive structure formed by the first and second paths can increase the area of ​​the conductive path, reduce the stroke of the conductive path, and thus reduce the contact impedance, thereby improving the conductive performance.
